PROPOSED ARRANGEMENT – YOUR VOTE IS VERY IMPORTANT

Dear Stockholders,

I am pleased to inform you that Chord Energy Corporation, a Delaware corporation (“Chord”), Spark Acquisition ULC, an unlimited liability company organized and existing under the laws of the Province of Alberta, Canada and a wholly owned subsidiary of Chord (“Canadian Sub”), and Enerplus Corporation, a corporation existing under the laws of the Province of Alberta, Canada (“Enerplus”), have agreed to a strategic business combination transaction whereby Chord (through Canadian Sub) will acquire all of the issued and outstanding Enerplus common shares (each, an “Enerplus common share”) pursuant to a plan of arrangement (as defined below) (the “arrangement”) with Enerplus becoming a wholly-owned subsidiary of Chord. Upon completion of the arrangement, Enerplus shareholders will receive 0.10125 of a share of Chord common stock, par value $0.01 per share (“Chord common stock”), and $1.84 in cash, in exchange for each Enerplus common share held (other than Enerplus common shares held by dissenting Enerplus shareholders), subject to adjustment if applicable, pursuant to the terms of an arrangement agreement entered into by Chord, Canadian Sub and Enerplus on February 21, 2024 (as may be amended from time to time, the “arrangement agreement”).

The arrangement will be implemented by way of a Canadian plan of arrangement (the “plan of arrangement”) in accordance with the Business Corporations Act (Alberta) and is subject to the approval by the Court of King’s Bench of Alberta (the “Court”), Chord stockholders and Enerplus shareholders and regulatory approvals in Canada and the U.S. and certain other customary conditions precedent. Upon completion of the arrangement, it is expected that Chord stockholders will own approximately 67% and Enerplus shareholders will own approximately 33% of the combined company on a fully diluted basis.

We are sending you the accompanying proxy statement to cordially invite you to attend a special meeting of the stockholders of Chord (the “special meeting”), which will be held entirely online at the following website: www.virtualshareholdermeeting.com/CHRD2024SM, at 9:00 AM, Central Time, on May 14, 2024, or such other date, time and place to which the special meeting may be adjourned or postponed, for the purpose of considering and voting upon the following proposals in connection with the arrangement:

(a) Proposal No. 1 – The Stock Issuance Proposal – to approve the issuance of shares of Chord common stock to Enerplus shareholders in connection with the arrangement (the “stock issuance proposal”);

(b) Proposal No. 2 – The Charter Amendment Proposal – to approve the amendment to the Amended and Restated Certificate of Incorporation of Chord, as amended (the “Charter Amendment”), to increase the number of authorized shares of Chord common stock from 120,000,000 shares to 240,000,000 shares (the “charter amendment proposal”); and

(b) Proposal No. 3 – The Adjournment Proposal – to approve the adjournment or postponement of the special meeting, if necessary or appropriate, including to solicit additional proxies if there are not sufficient votes to approve the stock issuance proposal, subject to the provisions of the arrangement agreement.

After careful consideration, the Chord board of directors has unanimously determined that it is advisable and in the best interests of Chord and its stockholders to consummate the arrangement with Enerplus as contemplated by the arrangement agreement and adopt the Charter Amendment, conditioned upon the closing of the arrangement (the “Closing”). The Chord board of directors unanimously recommends that you vote “FOR” each of the proposals described above.

The accompanying proxy statement provides you with information about the arrangement, the Charter Amendment and the special meeting. Chord encourages you to read the proxy statement carefully and in its entirety, including the arrangement agreement and the Charter Amendment, which are attached thereto as Annex A and Annex B, respectively. Before deciding how to vote, you should consider the risk factors discussed in the “Risk Factors” section of the proxy statement. You may also obtain more information about Chord and Enerplus from the documents each of them has filed with the Securities and Exchange Commission (the “SEC”) as described under the “Where You Can Find More Information” section of the proxy statement.

YOUR VOTE IS VERY IMPORTANT, NO MATTER HOW MANY SHARES YOU OWN.

The arrangement cannot be completed unless the stock issuance proposal is approved. Approval of the stock issuance proposal and the adjournment proposal requires the affirmative vote of a majority of the voting power of shares of Chord common stock present in person (online) or represented by proxy and entitled to vote thereon at the special meeting. Approval of the charter amendment proposal is not a condition to consummating the arrangement, however, adoption of the Charter Amendment is conditioned upon the Closing. Approval of the charter amendment proposal requires the affirmative vote of the holders of a majority of the voting power of shares of Chord common stock entitled to vote. An abstention from voting at the special meeting will have the same effect as a vote “AGAINST” the stock issuance proposal, the charter amendment proposal and the adjournment proposal. Abstentions are counted for purposes of determining whether a quorum is present at the special meeting. The failure of a Chord stockholder to submit a proxy or vote at the special meeting will have no effect on the outcome of the stock issuance proposal and the adjournment proposal and will have the same effect as a vote “AGAINST” the charter amendment proposal. Banks, brokers and other nominees that hold their customers’ shares in street name may not vote their customers’ shares on “non-routine” matters without instructions from their customers. As the stock issuance proposal and the adjournment proposal to be voted upon at the special meeting are considered “non-routine,” such organizations do not have discretion to vote on any proposal for which they do not receive instructions from their customers (this is referred to in this context as a “broker non-vote”). Therefore, if you fail to provide your bank, broker or other nominee with any instructions regarding how to vote your shares with respect to the stock issuance proposal and the adjournment proposal, your shares will not be considered present at the special meeting, will not be counted for purposes of determining the presence of a quorum and will not be voted on the stock issuance proposal and the adjournment proposal. Because the charter amendment proposal is considered a “routine” proposal, brokers, banks, and other nominees have discretionary authority to vote on the charter amendment proposal. Accordingly, we do not expect broker non-votes in connection with the charter amendment proposal.

Whether or not you plan to attend the special meeting in person (online), you are requested to promptly vote your shares by completing, signing and dating the enclosed proxy card or voting instruction form and returning it in the postage-paid envelope provided, or by voting over the telephone or via the internet as instructed in these materials. If you sign, date and mail your proxy card without indicating how you wish to vote, your vote will be counted as a vote “FOR” each of the proposals described above. If your shares are held in the name of a bank, broker or other nominee, please follow the instructions provided by that institution to vote your shares.

I strongly support the proposed arrangement of Chord with Enerplus and the Charter Amendment and join with our board of directors in unanimously recommending that you vote “FOR” each of the proposals described in this proxy statement.

Thank you for your continued support of Chord.

By Order of the Board of Directors,

Daniel E. Brown

However, the absence of these words does not mean that the statements are not forward-looking.

Chord cautions investors that any forward-looking statements are subject to known and unknown risks and uncertainties, many of which are outside of Chord’s control, and which may cause actual results and future trends to differ materially from those matters expressed in, or implied or projected by, such forward-looking statements, which speak only as of the date of this proxy statement.

• Enerplus may have liabilities that are not known to Chord;

• the uncertainty of the value of the stock consideration due to the fixed exchange ratio and potential fluctuation in the market price of Chord common stock;

• the arrangement agreement contains restrictions on Chord’s ability to pursue alternative transactions during the pendency of the arrangement without Enerplus consent;

• if the arrangement is terminated under certain circumstances Chord may be obligated to pay a termination fee to Enerplus, the cost of which could require Chord to draw on its credit facilities or use cash on hand that would have otherwise been available for operations, distributions or other general corporate purposes; and

Chord does not assume any obligation to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements were made or to reflect the occurrence of unanticipated events except as required by federal securities laws.

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING

The following questions and answers briefly address some commonly asked questions about the arrangement and other matters being considered at the special meeting. The following questions and answers do not include all the information that is important to our stockholders with respect to the arrangement. We urge our stockholders to carefully read this entire proxy statement, including its annexes and other documents incorporated by reference into this proxy statement.

Q: Why am I receiving this proxy statement?

A: Chord has agreed to acquire Enerplus pursuant to the terms and conditions of the arrangement agreement and the plan of arrangement that are described in this proxy statement. If completed, the arrangement will result in Canadian Sub, a wholly-owned subsidiary of Chord, acquiring all of the issued and outstanding Enerplus common shares in exchange for newly issued shares of Chord common stock and cash pursuant to the plan of arrangement. As a result, Enerplus will become a wholly-owned subsidiary of Chord. Chord common stock representing approximately 49% of Chord’s outstanding common stock will be issued to Enerplus shareholders in the arrangement. Immediately after the completion of the arrangement, it is expected that Chord’s former stockholders will own approximately 67% and Enerplus shareholders will own approximately 33% of the combined company on a fully diluted basis. A portion of the consideration to Enerplus shareholders will be paid in cash; based on the number of outstanding Enerplus common shares as of March 15, 2024, the aggregate cash consideration to be paid to Enerplus shareholders is estimated to be approximately $376 million. A copy of the arrangement agreement is attached to this proxy statement as Annex A.

You are receiving this proxy statement because you have been identified as a holder of Chord common stock on the record date. This proxy statement is being used to solicit proxies on behalf of the Chord board of directors for the special meeting to obtain the required approval of Chord stockholders. This proxy statement contains important information about the arrangement and related transactions, the Charter Amendment and the special meeting, and you should read it carefully.

In order to complete the arrangement, Chord stockholders must approve the issuance of Chord common stock, Enerplus shareholders must approve the arrangement, Enerplus must obtain a final order from the Court approving the arrangement and all other conditions to the arrangement, including receipt of certain Regulatory Approvals, must be satisfied or waived. Enerplus will hold a separate shareholder meeting to obtain the required approval of its shareholders.

Q: What will I receive under the arrangement?

A: Chord stockholders will not receive any consideration in the arrangement. Chord stockholders will continue to own their existing shares of Chord common stock after the arrangement. Immediately after the completion of the arrangement, it is expected that Chord stockholders will own approximately 67% and Enerplus shareholders will own approximately 33% of the combined company on a fully diluted basis.

Q: When and where is the special meeting?

A: The special meeting will be held entirely online at the following website: www.virtualshareholdermeeting.com/CHRD2024SM, on May 14, 2024 at 9:00 AM, Central Time.

Q: How do I attend the special meeting?

A: Chord stockholders will only be able to attend the Chord special meeting virtually via live audio webcast, which can be accessed by visiting www.virtualshareholdermeeting.com/CHRD2024SM. A Chord stockholder may participate, vote and examine Chord’s stockholder list at the Chord special meeting by

visiting www.virtualshareholdermeeting.com/CHRD2024SM and using the control number found on such stockholder’s proxy card or in the instructions that accompanied your proxy materials. For additional information on attending the special meeting, please see “Special Meeting.”

Q: What will the Chord stockholders be asked to vote on at the special meeting?

A: At the special meeting, Chord stockholders will be asked to consider and vote on the following proposals:

1. Proposal No. 1 – The Stock Issuance Proposal – to approve the issuance of shares of Chord common stock to Enerplus shareholders in connection with the arrangement;

2. Proposal No. 2 – The Charter Amendment Proposal – to approve the Charter Amendment to increase the number of authorized shares of Chord common stock from 120,000,000 shares to 240,000,000 shares; and

3. Proposal No. 3 – The Adjournment Proposal – to approve the adjournment or postponement of the special meeting, if necessary or appropriate, including to solicit additional proxies if there are not sufficient votes to approve the stock issuance proposal, subject to the provisions of the arrangement agreement.

Q: What will the Enerplus shareholders be asked to vote on?

A: Enerplus shareholders will not be asked to vote on any of the proposals to be considered and voted upon at the special meeting. Rather, pursuant to the arrangement agreement, Enerplus shareholders will be asked to vote on the arrangement resolution at the Enerplus shareholder meeting.

The Enerplus shareholder meeting is expected to be held on May 24, 2024. Among other things, the Closing is conditional on the approval of the arrangement resolution by the affirmative vote of at least two-thirds of the votes cast on the arrangement resolution by Enerplus shareholders present in person (online) or represented by proxy and entitled to vote at the Enerplus shareholder meeting.

Q: Who is eligible to vote at the special meeting?

A: Holders of Chord common stock as of the record date are eligible to vote at the special meeting.

Q: How many votes do Chord stockholders have?

A: Holders of Chord common stock are entitled to cast one vote on each proposal properly brought before the special meeting for each share of Chord common stock that such holder owned at the record date.

Q: What constitutes a quorum for the special meeting?

A: The holders of a majority of the shares of Chord common stock issued and outstanding and entitled to vote at the special meeting must be present in person (online) or represented by proxy in order to constitute a quorum for all matters to come before the special meeting. Abstentions are counted for purposes of determining whether a quorum is present at the special meeting. Banks, brokers and other nominees that hold their customers’ shares in street name may not vote their customers’ shares on “non-routine” matters without instructions from their customers. As the share issuance proposal and the adjournment proposal to be voted upon at the special meeting are considered “non-routine,” such organizations do not have discretion to vote on any proposal for which they do not receive instructions from their customers (this is referred to in this context as a “broker non-vote”). Therefore, if you fail to provide your bank, broker or other nominee with any instructions regarding how to vote your shares with respect to the stock issuance proposal and the adjournment proposal, your shares will not be considered present at the special meeting, will not be counted for purposes of determining the presence of a quorum and will not be voted with respect

7

to the stock issuance proposal and the adjournment proposal. If you provide instructions to your bank, broker or other nominee which indicate how to vote your shares with respect to one proposal but not with respect to the other proposal, your shares will be considered present at the special meeting and be counted for purposes of determining the presence of a quorum and voted, as instructed, with respect to the appropriate proposal, but will not be voted with respect to the other proposal. Because the charter amendment proposal is considered a “routine” proposal, brokers, banks and other nominees have discretionary authority to vote on the charter amendment proposal. Accordingly, we do not expect broker non-votes in connection with the charter amendment proposal.

If a quorum is not present at the special meeting, Chord’s chair of the board of directors, or the person presiding as chairman of the special meeting, may adjourn the special meeting to continue to solicit proxies. Regardless of whether a quorum is present at the special meeting, Chord’s chair of the board or the person presiding as chairman of the special meeting may adjourn the special meeting to a later date, without notice other than announcement at the special meeting. If an adjournment is for more than 30 days, or if after the adjournment a new record date is fixed for the adjourned special meeting, Chord will provide notice of the adjourned special meeting to each Chord stockholder of record entitled to vote at that special meeting scheduled to a later date.

Q: What vote by the Chord stockholders is required to approve the stock issuance proposal?

A: Pursuant to the Nasdaq Listing Rule 5635(a) and the Chord Bylaws, approval of the stock issuance proposal will require the affirmative vote of a majority of the voting power of shares of Chord common stock present in person (online) or represented by proxy and entitled to vote thereon at the special meeting.

Q: What vote by the Chord stockholders is required to approve the charter amendment proposal?

A: Pursuant to the Chord Certificate of Incorporation, approval of the charter amendment proposal will require the affirmative vote of a majority of the voting power of shares of Chord common stock entitled to vote thereon at the special meeting.

Q: Why is my vote important?

A: In order to complete the arrangement, Chord stockholders must approve the stock issuance proposal. Approval of the charter amendment proposal is not a condition to consummating the arrangement, however, adoption of the Charter Amendment is conditioned upon the Closing. An abstention from voting at the special meeting will have the same effect as a vote “AGAINST” the stock issuance proposal and the charter amendment proposal. Abstentions are counted for purposes of determining whether a quorum is present at the special meeting. The failure of a Chord stockholder to submit a proxy or vote at the special meeting will have no effect on the outcome of the stock issuance proposal and will have the same effect as a vote “AGAINST” the charter amendment proposal. Banks, brokers and other nominees that hold their customers’ shares in street name may not vote their customers’ shares on “non-routine” matters without instructions from their customers. As the stock issuance proposal and the adjournment proposal to be voted upon at the special meeting are considered “non-routine,” such organizations do not have discretion to vote on the stock issuance proposal and the adjournment proposal with a broker non-vote. Therefore, if you fail to provide your banks, broker or other nominee with any instructions regarding how to vote your shares with respect to the stock issuance proposal and the adjournment proposal, your shares will not be considered present at the special meeting, will not be counted for purposes of determining the presence of a quorum and will not be voted on the stock issuance proposal and the adjournment proposal. Because the charter amendment proposal is considered a “routine” proposal, brokers, banks, and other nominees have discretionary authority to vote on the charter amendment proposal. Accordingly, we do not expect broker non-votes in connection with the charter amendment proposal.

Q: Why am I being asked to consider and vote on the stock issuance proposal?

A: As Chord common stock is listed for trading on the Nasdaq, issuances of shares of Chord common stock are subject to the Nasdaq Listing Rules. Pursuant to Nasdaq Listing Rule 5635(a), stockholder approval is required prior to the issuance of securities in connection with the acquisition of stock or assets of another company that would result in (i) the issuance, or potential issuance, of shares of common stock (including upon the conversion or exercise of securities into common stock) (a) having voting power equal to or in excess of 20% of the voting power of the common stock outstanding prior to the issuance of the common stock or securities convertible into or exercisable for common stock or (b) in excess of 20% of the number of shares of common stock outstanding prior to the issuance of the common stock or securities convertible into or exercisable for common stock. The number of shares of Chord common stock to be issued to Enerplus shareholders as consideration for the arrangement will exceed 20% of the number of shares of Chord common stock outstanding before the issuance. Therefore, under Nasdaq Listing Rule 5635(a), stockholder approval of the stock issuance proposal is required.

Q: Why am I being asked to consider and vote on the charter amendment proposal?

A: Given that the stock consideration would result in the issuance of a significant number of shares of Chord common stock, the Chord board of directors believes that the increased number of authorized shares of Chord common stock contemplated by the charter amendment proposal is important to the combined company in order for additional shares to be available for issuance from time to time if needed for such corporate purposes as may be determined by the Chord board of directors, without further action or authorization by Chord stockholders (except as required by applicable law or Nasdaq rules). The additional 120,000,000 shares of common stock authorized would be a part of the existing class of Chord common stock and, if issued, would have the same rights and privileges as the shares of Chord common stock presently issued and outstanding.

Q: Will the newly issued shares of Chord common stock be traded on an exchange?

A: It is a condition to the completion of the arrangement that the shares of Chord common stock to be issued to Enerplus shareholders in exchange for their Enerplus common shares pursuant to the arrangement be approved for listing on the Nasdaq, subject to official notice of issuance. Accordingly, Chord has agreed to use reasonable best efforts to obtain approval of the listing of the stock consideration for trading on the Nasdaq. Chord will provide the required notice to the Nasdaq of the listing of the shares of Chord common stock to be issued in connection with the arrangement prior to the Closing.

Q: What are Chord’s reasons for proposing the arrangement and entering into the arrangement agreement?

A: The Chord board of directors concluded that the arrangement provides significant potential benefits to Chord, including, among other things, a material increase in Chord’s scale and meaningful increase in Chord’s total inventory, strong free cash flow and attractive reinvestment rates and increased financial strength and flexibility, that outweigh the uncertainties, risks and potentially negative factors relevant to the arrangement. For a more detailed discussion of the reasoning of the Chord board of directors, see “The Arrangement—Chord’s Reasons for the Arrangement” and “The Arrangement—Recommendations of the Chord Board of Directors” sections of this proxy statement.

Q: What is an arrangement?

A: An arrangement is a statutory procedure under Canadian corporate law that allows companies to carry out transactions upon receiving shareholder and court approval that then becomes binding on all other shareholders by operation of law. The arrangement that is being proposed by Enerplus, a corporation

9

existing under the ABCA, will allow Canadian Sub, a wholly-owned subsidiary of Chord, to acquire all of the outstanding Enerplus common shares pursuant to a plan of arrangement under the ABCA in exchange for applicable stock consideration and cash consideration.

Q: How does the Chord board of directors recommend that I vote?

A: The Chord board of directors unanimously recommends that you vote “FOR” each of the proposals to be considered and voted upon at the special meeting.

Q: What do I need to do now?

A: After you have carefully read and considered the information contained in or incorporated by reference into this proxy statement, please submit your proxy in accordance with the instructions set forth on the applicable enclosed proxy card, or complete, sign, date, and return the applicable enclosed proxy card in the self-addressed, stamped envelope provided as soon as possible so that your shares will be represented and voted at the special meeting. For additional information on voting procedures, please see “The Special Meeting.”

Q: How do I vote?

A: You may vote by any of the four methods listed below. If your Chord common stock is held in “street name” by your bank, broker or other nominee, please see “How do I vote if my Chord common stock is held in “street name” by my bank, broker or other nominee?” below.

 Internet. You may vote on the Internet at http://www.proxyvote.com. This website also allows electronic proxy voting using smartphones, tablets and other web-connected mobile devices (additional charges may apply pursuant to your service provider plan). Simply follow the instructions that accompanied your proxy materials. If you vote on the Internet, you can request electronic delivery of future proxy materials. Internet voting facilities for Chord stockholders of record will be available 24 hours a day and will close at 11:59 p.m. (Eastern Time) on May 13, 2024.

 Telephone. You may vote by telephone by following the instructions that accompanied your proxy materials. Easy-to-follow voice prompts allow you to vote your stock and confirm that your vote has been properly recorded. Telephone voting facilities for Chord stockholders of record will be available 24 hours a day and will close at 11:59 p.m. (Eastern Time) on May 13, 2024.

 Mail. If you received a proxy card by mail, you may vote by mail by completing, signing, dating and returning your proxy card in the pre-addressed, postage-paid envelope provided.

If mailed, your completed and signed proxy card must be received by May 13, 2024.

 Meeting. You may attend and vote electronically at the special meeting.

The Chord board of directors recommends that you vote using one of the first three methods discussed above, as it is not practical for most Chord stockholders to attend and vote at the special meeting. Using one of the first three methods discussed above to vote will not limit your right to vote at the special meeting if you later decide to attend in person (online).

10

Q: How do I vote if my Chord common stock is held in street name by my bank, broker or other nominee?

A: If your shares are held in “street name” by your bank, broker or other nominee, you are considered the beneficial owner of shares held in street name, and the proxy materials will be forwarded to you by your bank, broker or nominee. The bank, broker or nominee is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your bank, broker or nominee how to vote. Beneficial owners that receive the proxy materials by mail from the stockholder of record should follow the instructions included in those materials (usually a voting instruction card) to transmit voting instructions.

Q: Who will count the votes?

A: The votes at the special meeting will be tabulated and certified by the inspector of elections appointed by the Chord board of directors.

Q: What should I do if I receive more than one set of materials?

A: You may receive more than one set of voting materials for the special meeting, including multiple copies of this proxy statement and multiple proxy cards or voting instruction forms. For example, if you hold your shares of Chord common stock in more than one brokerage account, you will receive a separate voting instruction form for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered in more than one name, you will receive more than one proxy card. Please submit each separate proxy or voting instruction form that you receive by following the instructions set forth in each separate proxy or voting instruction form. If you fail to submit each separate proxy or voting instruction form that you receive, not all of your shares will be voted.

Q: What happens if I sell my shares of Chord common stock before the special meeting?

A: The record date for Chord stockholders entitled to vote at the special meeting is earlier than the date of the special meeting. If you transfer your shares of Chord common stock after the record date, but before the date of the special meeting, you will retain your right to vote at the special meeting unless special arrangements are made between you and the person to whom you transfer your shares. If you sold your shares after the record date you are encouraged to still vote the shares you owned on the record date.

Q: Do any of the officers or directors of Chord have interests in the arrangement that may differ from or be in addition to my interests as a Chord stockholder?

A: In considering the recommendation of the Chord board of directors that Chord stockholders vote to approve the stock issuance proposal, the charter amendment proposal and the adjournment proposal, Chord stockholders should be aware that, aside from their interests as Chord stockholders, Chord’s directors and executive officers have interests in the arrangement that may be different from, or in addition to, the interests of Chord stockholders generally. These interests are described in more detail in the section entitled “The Arrangement — Interests of Chord Directors and Executive Officers in the Arrangement.” The Chord board of directors was aware of and considered these potential interests, among other matters, in evaluating and negotiating the arrangement agreement and the arrangement, in approving the arrangement and in recommending the approval of the stock issuance proposal, the charter amendment proposal and the adjournment proposal. See “The Arrangement — Background of the Arrangement,” “The Arrangement — Recommendation of the Chord Board of Directors” and “The Arrangement — Chord’s Reasons for the Arrangement.”

Q: May I vote at the special meeting?

A: Yes. If you are a Chord stockholder of record on the record date, you may attend the special meeting and vote your shares electronically, in lieu of submitting your proxy by internet, by telephone, or by completing,

11

signing, dating, and returning the enclosed proxy card. Please note that attendance alone at the special meeting will not cause the voting of your shares; you must affirmatively vote the proxy card or meeting ballot provided.

If you are a beneficial owner of shares of Chord common stock, you are also invited to attend the special meeting. However, because you are not the Chord stockholder of record, you may not vote your shares in person (online) at the special meeting unless you request and obtain a “legal proxy” issued in your own name from your bank, broker or other nominee.

If you appoint a non-management proxy holder, please make sure he or she is aware and ensure he or she will attend and submit a vote on your behalf at the special meeting, with the proper authority from you, for your vote to count.

Q: How can I change or revoke my vote?

A: You may revoke your proxy before the voting polls are closed at the special meeting by (i) voting at a later time by Internet or telephone until 11:59 p.m. (Eastern Time) on May 13, 2024, (ii) voting in person (online) at the special meeting, (iii) delivering to Chord’s Corporate Secretary a proxy with a later date or a written revocation of your most recent proxy, or (iv) giving notice to the inspector of elections at the special meeting.

If your Chord common stock is held in street name by a bank, broker or other nominee, and you vote by proxy, you may later revoke your proxy by informing the holder of record in accordance with that entity’s procedures.

Q: Am I entitled to appraisal rights?

A: No. Under the DGCL, holders of shares of Chord common stock are not entitled to appraisal rights in connection with the arrangement or any of the matters to be acted on at the special meeting.

Q: I own warrants to acquire shares of Chord common stock. Can I vote at the special meeting? What will happened to my warrants in the arrangement?

A: No. No holders of any series of our warrants (whether legacy Oasis Petroleum Inc. or legacy Whiting Petroleum Corporation warrants) will have any right to vote at the special meeting on account of such warrant until, and only to the extent, such holders become holders of record of shares of Chord common stock issued upon settlement of the warrants by the record date. The arrangement will not impact the terms of any of our outstanding warrants.

Q: What is the size of the cash consideration?

A: Based on the number of outstanding Enerplus common shares as of March 15, 2024, the aggregate cash consideration to be paid to Enerplus shareholders would be equal to approximately $376 million.

Q: Is completion of the arrangement subject to any conditions?

A: Yes. Chord and Enerplus cannot complete the arrangement unless a number of conditions are satisfied or waived, including receipt of the required approvals from Chord stockholders, Enerplus shareholders and the Court, in addition to the Regulatory Approvals. See “The Arrangement Agreement and the Plan of Arrangement—Conditions to Completion of the Arrangement” section of this proxy statement for a more complete summary of the conditions that must be satisfied or waived prior to completion of the arrangement.

12

Q: What happens if the arrangement is terminated?

A: If the arrangement is terminated, Enerplus will not be combined with Chord, and Chord and Enerplus will continue to operate as separate entities as they did before. The arrangement agreement contains certain termination rights for both Chord and Enerplus, including, among others, (i) mutual consent by Chord and Enerplus, (ii) by either Chord or Enerplus if (A) the arrangement shall not have been consummated on or prior to the termination date, or (B) a final non-appealable governmental order has been issued prohibiting the arrangement, (iii) by either Chord or Enerplus if either the Enerplus shareholder approval of the arrangement resolution or Chord stockholder approval of the stock issuance proposal shall not have been obtained, (iv) by a party if the other party breaches any of its representations, warranties or covenants in the arrangement agreement in a manner that would cause the corresponding condition to not be satisfied, subject to certain conditions, (v) by a party if the other party’s board of directors changes its recommendation with respect to the arrangement, (vi) by a party if there is a willful and material breach by the other party of the applicable restrictions with respect to soliciting competing business combination transactions and (vii) by a party in order for such party to enter into a definitive agreement with respect to a superior proposal (provided that such party has not materially breached the applicable non-solicitation restrictions).

The arrangement agreement further provides that, upon termination of the arrangement agreement under certain circumstances, Enerplus will be required to pay to Chord a termination fee of $127 million in connection with such termination, or Chord will be required to pay to Enerplus a termination fee of $240 million in connection with such termination. See “The Arrangement Agreement and the Plan of Arrangement—Termination of the Arrangement Agreement” section of this proxy statement for a more complete summary of the termination provisions under the arrangement agreement.

Q: When does Chord expect the arrangement to become effective?

A: The arrangement is currently expected to close by mid-year 2024. The Closing is conditional on Enerplus shareholders approving the arrangement resolution, the approval of Chord stockholders of the stock issuance proposal, and the satisfaction of other closing conditions. See “The Arrangement Agreement and the Plan of Arrangement—Conditions to Completion of the Arrangement” section of this proxy statement.

Q: What will happen if the arrangement is completed?

A: If the arrangement is completed, Canadian Sub will acquire all of the issued and outstanding Enerplus common shares and Enerplus will become a wholly-owned subsidiary of Chord. Chord intends to have the Enerplus common shares delisted from the TSX and the NYSE as promptly as possible following completion of the arrangement. In addition, it is expected that Chord will, subject to applicable law, apply to have Enerplus cease to be a reporting issuer in all jurisdictions in which it is a reporting issuer and thus will terminate Enerplus’ reporting obligations in Canada and the United States following completion of the arrangement.

In addition, Chord will become a reporting issuer in each of the provinces and territories of Canada by virtue of the completion of the arrangement. Subject to certain exceptions, Chord will be generally exempt from Canadian statutory financial and other continuous and timely reporting requirements, including the requirement for insiders of Chord to file reports with respect to trades of Chord securities, provided Chord complies with the requirements of applicable U.S. securities laws and U.S. market requirements in respect of all financial and other continuous and timely reporting matters, and Chord files with the relevant Canadian securities regulatory authorities copies of its documents filed with the SEC under the Exchange Act.

Q: Who will be the directors and executive officers of the combined company following the arrangement?

A: The arrangement agreement provides that at the effective time, the Chord board of directors will consist of up to eleven members, of whom (i) seven directors will be designated by Chord, which designees will consist of

13

Daniel E. Brown, Chord’s President and Chief Executive Officer, and the following six independent directors: Susan M. Cunningham, Douglas E. Brooks, Samantha F. Holroyd, Kevin S. McCarthy, Anne Taylor and Marguerite N. Woung-Chapman, and (ii) up to four directors will be designated by Enerplus, which designees will consist of Hilary Foulkes, Chair of the Enerplus board of directors, Ian C. Dundas, Enerplus’ President and Chief Executive Officer, and the following two independent directors: Ward Polzin and Jeffrey Sheets. Susan M. Cunningham will continue as the chair of the Chord board of directors. See “The Arrangement—Board of Directors Following the Arrangement” section of this proxy statement.

Chord anticipates that Mr. Brown will serve as Director, President and Chief Executive Officer of the combined company. The remainder of Chord’s leadership team will include Michael Lou, Chord’s Executive Vice President, Chief Strategy Officer and Chief Commercial Officer, Richard Robuck, Chord’s Executive Vice President and Chief Financial Officer, Darrin Henke, Chord’s Executive Vice President and Chief Operating Officer and Shannon Kinney, Chord’s Executive Vice President, Chief Administrative Officer and General Counsel, who will continue to serve in the respective capacities in the combined company.

Mr. Dundas, effective as of immediately following the effective time, will serve as an advisor to the Chief Executive Officer of Chord pursuant to a letter agreement between Chord and Mr. Dundas, dated February 21, 2024 (the “Letter Agreement”). It is expected that Mr. Dundas will serve in such role for twelve months following the effective time (such period, the “Term”). In his role as an advisor to the Chief Executive Officer, Mr. Dundas will be eligible to receive an annual base salary of $500,000, less applicable withholdings and deductions. During the Term, Mr. Dundas will also serve as a member of the Chord board of directors. Mr. Dundas will not receive any additional compensation for his service as a member of the Chord board of directors. As soon as reasonably practicable following the effective time, Mr. Dundas will receive a one-time restricted stock unit award (the “Dundas RSU Award”), pursuant to the equity compensation plan of Chord, with a grant date fair market value of $2,000,000. The Dundas RSU Award will fully vest on the last day of the Term, subject to Mr. Dundas’s continued employment through such date. For the duration of the Term, Mr. Dundas is required to maintain a minimum ownership of 25,000 shares of Chord common stock (in addition to the shares subject to the Dundas RSU Award). Under the Letter Agreement, Mr. Dundas may participate in outside business activities during the Term, so long as (i) after giving effect to the arrangement, such business activities are not in competition with Chord, Enerplus or any of their respective subsidiaries within the state of North Dakota during the Term, and (ii) Mr. Dundas does not disclose any confidential, competitively valuable, non-public or proprietary information to any person or entity, and does not use any such information except for the benefit of Chord and its subsidiaries. For additional information, see “The Arrangement—Management Following the Arrangement” section of this proxy statement.

Q: Are there any risks I should consider in connection with the arrangement?

A: Yes. There are a number of risk factors relating to Chord’s business and operations, the arrangement and the combined company’s business and operations, all of which should be carefully considered. See the “Risk Factors” section of this proxy statement.

Q: Is this Chord’s annual meeting? Will I be voting on the election of directors at the special meeting?

A: No. This is not Chord’s annual meeting and you will not be asked to elect directors at the special meeting. The special meeting will be held entirely online at the following website: www.virtualshareholdermeeting.com/CHRD2024SM, at 9:00 AM, Central Time, on May 14, 2024, unless adjourned or postponed to a later date.

In connection with this recommendation, the Chord board of directors has determined that it is advisable and in the best interests of Chord and its stockholders to issue the Chord common stock in connection with the arrangement and adopt the Charter Amendment, conditioned upon the Closing. See “The Arrangement—Chord’s Reasons for the Arrangement” and “The Arrangement—Recommendations of the Chord Board of Directors” sections of this proxy statement for more information about the factors considered by the Chord board of directors.

Required Vote

Each share of Chord common stock is entitled to one vote at the special meeting. The holders of a majority of the shares of Chord common stock issued and outstanding and entitled to vote at the special meeting must be present in person (online) or represented by proxy in order to constitute a quorum for all matters to come before the special meeting. Abstentions are counted for purposes of determining whether a quorum is present at the special meeting. Banks, brokers and other nominees that hold their customers’ shares in street name may not vote their customers’ shares on “non-routine” matters without instructions from their customers. As the stock issuance proposal and the adjournment proposal to be voted upon at the special meeting are considered “non-routine,” such organizations do not have discretion to vote on the stock issuance proposal and the adjournment proposal with a broker non-vote. Therefore, if you fail to provide your bank, broker or other nominee with any instructions regarding how to vote your shares with respect to the stock issuance proposal and the adjournment proposal, your shares will not be considered present at the special meeting, will not be counted for purposes of determining the presence of a quorum and will not be voted on the stock issuance proposal and the adjournment proposal. If you provide instructions to your bank, broker or other nominee which indicate how to vote your shares with respect to one proposal but not with respect to the other proposal, your shares will be considered present at the special meeting and will be counted for purposes of determining the presence of a quorum and voted, as instructed, with respect to the appropriate proposal, but will not be voted with respect to the other proposal. Because the charter amendment proposal is considered a “routine” proposal, brokers, banks, and other nominees have discretionary authority to vote on the charter amendment proposal. Accordingly, we do not expect broker non-votes in connection with the charter amendment proposal.

Approval of the stock issuance proposal and the adjournment proposal presented at the special meeting will require the affirmative vote of a majority of the voting power of shares of Chord common stock present in person (online) or represented by proxy and entitled to vote thereon at the special meeting. Approval of the charter

17

amendment proposal presented at the special meeting will require the affirmative vote of a majority of the voting power of shares of Chord common stock entitled to vote thereon. An abstention from voting at the special meeting will have the same effect as a vote “AGAINST” the stock issuance proposal, the charter amendment proposal and the adjournment proposal, respectively. The failure of a Chord stockholder to submit a proxy or vote at the special meeting will have no effect on the outcome of the stock issuance proposal and the adjournment proposal and will have the same effect as a vote “AGAINST” the charter amendment proposal. A broker non-vote will not be voted on the stock issuance proposal or the adjournment proposal.

Security Ownership of Certain Beneficial Owners and Management

As of the close of business on April 8, 2024, the current directors and executive officers of Chord were deemed to beneficially own 289,230 shares of Chord common stock, constituting, in the aggregate, less than one percent of the shares of Chord common stock outstanding on that date. Beneficial ownership is determined in accordance with SEC rules as described under “The Special Meeting—Security Ownership of Certain Beneficial Owners and Management” section of this proxy statement.

The Arrangement

The arrangement agreement provides that, at the effective time, Canadian Sub will acquire all of the issued and outstanding Enerplus common shares with Enerplus continuing as a wholly-owned subsidiary of Chord. The arrangement will be implemented under the ABCA and requires, among others, approval of (a) at least two-thirds of the votes cast by Enerplus shareholders who vote in person (online) or by proxy at the Enerplus shareholder meeting and (b) the Court. After giving effect to the arrangement, Canadian Sub will own all of the outstanding Enerplus common shares.

A copy of the arrangement agreement and the plan of arrangement are attached as Annex A to this proxy statement. You are urged to read the arrangement agreement and the plan of arrangement in their entirety because they are the legal documents that govern the arrangement. For more information on the arrangement, the arrangement agreement and the plan of arrangement, see “The Arrangement Agreement and the Plan of Arrangement” section of this proxy statement.

Consideration Received Pursuant to the Arrangement

If the arrangement is completed, Canadian Sub will acquire all of the Enerplus common shares, and each Enerplus shareholder (other than Enerplus common shares held by dissenting Enerplus shareholders) will receive (i) 0.10125 of a share of Chord common stock, and (ii) $1.84 in cash, in exchange for each Enerplus common share they hold, subject to adjustment as set forth in the arrangement agreement, if applicable. Upon completion of the arrangement, it is expected that Chord stockholders will own approximately 67%, and Enerplus shareholders will own approximately 33% of the combined company on a fully diluted basis. Based on the number of Enerplus common shares as of March 15, 2024, the aggregate cash consideration is estimated to be approximately $376 million.

Non-Solicitation of Alternative Transactions and Change in Recommendation

Chord and Enerplus each have agreed that, except as contemplated by the arrangement agreement, neither they nor any of their respective subsidiaries will (and Chord and Enerplus will, and will cause each of their respective subsidiaries to, use reasonable best efforts to cause its and their respective representatives not to):

• directly or indirectly initiate or solicit, or knowingly encourage or knowingly facilitate (including by way of furnishing non-public information relating to Chord or Enerplus or any of their respective

18

subsidiaries) any inquiries or the making or submission of any proposal that constitutes, or would reasonably be expected to lead to, an acquisition proposal, except as expressly permitted in the arrangement agreement;

• participate or engage in discussions or negotiations with, or disclose any non-public information or data relating to Chord or Enerplus or any of their subsidiaries or afford access to the properties, books or records of Chord or Enerplus or any of their respective subsidiaries with respect to, relating to, or in furtherance of, an acquisition proposal or any inquiry, proposal or offer that would reasonably be expected to lead to an acquisition proposal, unless (i) notice is provided to the other party, (ii) its board of directors determines such proposal could reasonably lead to a superior proposal and (iii) its board of directors determines in good faith that failure to participate in such discussions would be reasonably likely to be inconsistent with its fiduciary duties;

• accept an acquisition proposal or enter into any agreement, including any letter of intent, memorandum of understanding, agreement in principle, merger agreement, arrangement agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement, arrangement or understanding, (i) constituting or related to, or that would reasonably be expected to lead to, any acquisition proposal (other than an acceptable confidentiality agreement permitted pursuant to the arrangement agreement) or (ii) requiring or which would reasonably be expected to cause Chord or Enerplus to abandon, terminate or fail to consummate the arrangement; or

• (i) withhold, withdraw or qualify (or amend or modify in a manner adverse to the other party), or publicly propose to withhold, withdraw or qualify (or amend or modify in a manner adverse to the other party), the approval or recommendation or declaration of advisability, as applicable, by its board of directors or any such committee thereof of the arrangement agreement, the arrangement, the stock issuance proposal or the arrangement resolution of Enerplus, as applicable, (ii) endorse or recommend, adopt or approve, or propose publicly to endorse or recommend, adopt or approve any other acquisition proposal, (iii) fail to include the board of directors recommendation in its proxy statement or circular, as applicable, (iv) (x) as to Chord, in response to an acquisition proposal that is structured as a tender offer or exchange offer pursuant to Rule 14d-2 under the Exchange Act for outstanding shares of Chord common stock (other than by Enerplus or an affiliate of Enerplus), fail to recommend, in a solicitation/recommendation statement on Schedule 14D-9, against acceptance of such tender offer or exchange offer by the Chord stockholders on or prior to the earlier of (1) three (3) business days prior to the date of the special meeting or (2) ten (10) business days (as such term is used in Rule 14d-9 of the Exchange Act) after commencement of such tender offer or exchange offer, or (y) as to Enerplus, in response to an acquisition proposal that is structured as a takeover bid, fail to recommend, in a directors’ circular prepared by Enerplus, against acceptance of such takeover bid on or prior to the earlier of (1) three (3) business days prior to the date of the Enerplus shareholder meeting or (2) fifteen (15) days after the formal commencement of such takeover bid, (v) if an acquisition proposal has been publicly announced or disclosed (other than pursuant to the foregoing clause (iv)), fail to publicly reaffirm its board of directors recommendation on or prior to the earlier of five (5) business days following the written request of the other party or three (3) business days prior to the date of its meeting or (vii) make any other public statement that is inconsistent in any material respect with its board of directors recommendation.

Prior to receipt of the approval of its stockholders or shareholders, as applicable, in response to a bona fide written acquisition proposal that did not result from a breach of the arrangement agreement, and that its board of directors determines in good faith, after consultation with its financial advisor(s) and outside legal counsel, is a superior proposal and the failure to make an adverse recommendation change or terminate the arrangement agreement would be reasonably likely to be inconsistent with its fiduciary duties under applicable law, Chord or Enerplus board of directors, as applicable, may make an adverse recommendation change or terminate the

19

arrangement agreement pursuant to its terms; provided, however, that it will not be entitled to exercise its right to make an adverse recommendation change in response to a superior proposal (x) until four (4) business days after it provides written notice to the other party advising the other party that it has received an acquisition proposal that its board of directors has determined in good faith, after consultation with its financial advisor(s) and outside legal counsel, constitutes a superior proposal, including a copy of such superior proposal specifying the material terms and conditions thereof and any applicable transaction and financing documents, and identifying the person or group making such superior proposal, (y) if during such four (4) business day period, the other party proposes any alternative transaction (including any modifications to the terms of the arrangement agreement), unless its board of directors determines in good faith (after consultation with its financial advisor(s) and outside legal counsel, and taking into account all financial, legal, and regulatory terms and conditions of such alternative transaction proposal) that such previous superior proposal remains a superior proposal, and (z) unless its board of directors, after consultation with outside legal counsel, determines that the failure to make an adverse recommendation change would be reasonably likely to be inconsistent with its fiduciary duties under applicable law.

Notwithstanding the foregoing, other than in connection with a superior proposal, at any time prior to receipt of the approval of its stockholders or shareholders, as applicable, in response to an intervening event that is not related to any acquisition proposal, each of the Chord and Enerplus board of directors may make an adverse recommendation change if it:

• determines in good faith, after consultation with its outside legal counsel and any other advisor it chooses to consult, that the failure to make such adverse recommendation change would be reasonably likely to be inconsistent with its fiduciary duties under applicable law; and

• provides written notice to the other party advising the other party that it is contemplating making an adverse recommendation change and specifying the material facts and information constituting the basis for such contemplated determination; provided, however, that (x) it may not make an adverse recommendation change until the fourth business day after receipt by the other party of the notice of change and (y) during such four (4) business day period, at the request of the other party, it will negotiate in good faith with respect to any changes or modifications to the arrangement agreement which would allow it not to make such adverse recommendation change in response thereto.

Chord’s Reasons for the Arrangement

In evaluating the arrangement, including the issuance of Chord common stock to Enerplus shareholders in connection with the arrangement, the Chord board of directors consulted with Chord’s senior management, outside legal counsel and independent financial advisor. In recommending that Chord stockholders vote in favor of each of the proposals, the Chord board of directors also considered a number of factors that it believed supported its determination. For a more detailed discussion of the reasoning of the Chord board of directors, see

23

“The Arrangement—Chord’s Reasons for the Arrangement” and “The Arrangement—Recommendations of the Chord Board of Directors” sections of this proxy statement.

Recommendation of the Chord Board of Directors

After careful consideration, the Chord board of directors has determined that it is advisable and in the best interests of Chord and its stockholders to consummate the arrangement as contemplated by the arrangement agreement and adopt the Charter Amendment, conditioned upon the Closing. Accordingly, the Chord board of directors unanimously recommends that Chord stockholders vote:

• “FOR” the stock issuance proposal;

• “FOR” the charter amendment proposal; and

• “FOR” the adjournment proposal.

Opinion of Financial Advisor to Chord

Chord has engaged Citi as Chord’s financial advisor in connection with the arrangement. In connection with this engagement, Citi delivered a written opinion, dated February 21, 2024, to the Chord board of directors as to the fairness, from a financial point of view and as of the date of the opinion, to Chord of the consideration to be paid by Chord pursuant to the arrangement agreement. The full text of Citi’s written opinion, dated February 21, 2024, which describes the assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken, is attached as Annex C to this proxy statement and is incorporated into this proxy statement by reference. The description of Citi’s opinion set forth below is qualified in its entirety by reference to the full text of Citi’s opinion. Citi’s opinion was provided for the information of the Chord board of directors (in its capacity as such) in connection with its evaluation of the consideration from a financial point of view to Chord and did not address any other terms, aspects or implications of the arrangement. Citi expressed no view as to, and its opinion did not address, the underlying business decision of Chord to effect or enter into the arrangement, the relative merits of the arrangement as compared to any alternative business strategies that might exist for Chord or the effect of any other transaction that Chord might engage in or consider. Citi’s opinion was not intended to be and did not constitute a recommendation as to how the Chord board of directors, and is not intended to be and does not constitute a recommendation as to how any securityholder, should vote or act on any matters relating to the proposed arrangement or otherwise. For additional information, see “The Arrangement—Opinion of Financial Advisor to Chord” section of this proxy statement.

Board of Directors Following the Arrangement

Chord has agreed with Enerplus that it will take all actions necessary to ensure that, as of the effective time, the Chord board of directors will consist of up to eleven members, of whom: (i) seven directors will be designated by Chord, which designees will consist of Daniel E. Brown, Chord’s President and Chief Executive Officer, and the following six independent directors: Susan M. Cunningham, Douglas E. Brooks, Samantha F. Holroyd, Kevin S. McCarthy, Anne Taylor and Marguerite N. Woung-Chapman, and (ii) up to four directors will be designated by Enerplus, which designees will consist of Hilary Foulkes, Chair of the Enerplus board of directors, Ian C. Dundas, Enerplus’ President and Chief Executive Officer, and the following two independent directors: Ward Polzin and Jeffrey Sheets. Susan M. Cunningham will continue as the chair of the Chord board of directors.

Mr. Dundas, effective as of immediately following the effective time, will serve as an advisor to the Chief Executive Officer of Chord pursuant to the Letter Agreement. It is expected that Mr. Dundas will serve in such role for the Term. In his role as an advisor to the Chief Executive Officer, Mr. Dundas will be eligible to receive an annual base salary of $500,000, less applicable withholdings and deductions. During the Term, Mr. Dundas

24

will also serve as a member of the Chord board of directors. Mr. Dundas will not receive any additional compensation for his service as a member of the Chord board of directors. As soon as reasonably practicable following the effective time, Mr. Dundas will receive the Dundas RSU Award, pursuant to the equity compensation plan of Chord, with a grant date fair market value of $2,000,000. The Dundas RSU Award will fully vest on the last day of the Term, subject to Mr. Dundas’s continued employment through such date. For the duration of the Term, Mr. Dundas is required to maintain a minimum ownership of 25,000 shares of Chord common stock (in addition to the shares subject to the Dundas RSU Award). Under the Letter Agreement, Mr. Dundas may participate in outside business activities during the Term, so long as (i) after giving effect to the arrangement, such business activities are not in competition with Chord, Enerplus or any of their respective subsidiaries within the state of North Dakota during the Term, and (ii) Mr. Dundas does not disclose any confidential, competitively valuable, non-public or proprietary information to any person or entity, and does not use any such information except for the benefit of Chord and its subsidiaries. For additional information, see “The Arrangement—Management Following the Arrangement” section of this proxy statement.

Management Following the Arrangement

Chord anticipates that Mr. Brown will serve as Director, President and Chief Executive Officer of the combined company. The remainder of Chord’s leadership team will include Michael Lou, Executive Vice President, Chief Strategy Officer and Chief Commercial Officer, Richard Robuck, Chord’s Executive Vice President and Chief Financial Officer, Darrin Henke, Chord’s Executive Vice President and Chief Operating Officer and Shannon Kinney, Chord’s Executive Vice President, Chief Administrative Officer and General Counsel, who will continue to serve in the respective capacities in the combined company.

Interests of Chord Directors and Executive Officers in the Arrangement

In considering the recommendation of the Chord board of directors that you vote “FOR” each of the proposals, you should be aware that certain of Chord’s directors and executive officers have interests in the arrangement that may be different from, or in addition to, those of Chord stockholders generally. The Chord board of directors was aware of and considered these interests when it approved the arrangement agreement and the transactions contemplated thereby and recommended that Chord stockholders vote “FOR” each of the proposals. Such interests include that certain current directors and executive officers of Chord are expected to continue as directors and executive officers of Chord following the consummation of the arrangement.

Accounting Treatment

Chord and Enerplus prepare their respective financial statements in accordance with U.S. GAAP. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations, Chord will be treated as the acquirer for accounting purposes and will account for the arrangement as an acquisition of a business, which requires the determination of the acquirer, the purchase price, the acquisition date, the fair value of assets and liabilities of the acquiree and the measurement of goodwill, if any.

Court Approvals

The arrangement requires approval by the Court under Section 193 of the ABCA. Enerplus must first obtain the interim order which will, among other things, authorize and direct Enerplus to call, hold and conduct the Enerplus shareholder meeting and submit the arrangement to Enerplus shareholders for approval. Enerplus has scheduled an interim order hearing for April 23, 2024. Under the arrangement agreement, Enerplus is required to seek the final order as soon as reasonably practicable, but in any event not later than five business days following the later of the approval of the arrangement resolution by Enerplus shareholders at the Enerplus shareholder meeting and the approval of the stock issuance proposal, subject to the availability of the Court.

25

Regulatory Approvals

Antitrust Clearance

The completion of the arrangement is subject to antitrust review in the United States. Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and the rules promulgated thereunder, the transaction cannot be completed until the parties to the arrangement agreement have given notification and furnished information to the Federal Trade Commission (the “FTC”) and the United States Department of Justice (the “DOJ”), and until the applicable waiting period has expired or has been terminated.

On March 6, 2024, Chord and Enerplus each filed a premerger notification and report form under the HSR Act. The waiting period with respect to the notification and report forms filed under the HSR Act expired at 11:59 p.m., Eastern Time, on April 5, 2024.

At any time before or after consummation of the transaction, the FTC or the DOJ, or any state, could take such action under antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the transaction or seeking the divestiture of substantial assets of Chord or Enerplus or their respective subsidiaries. Private parties may also seek to take legal action under antitrust laws under certain circumstances.

Investment Canada Act Approval

Under the Investment Canada Act (Canada) (“Investment Canada Act”), certain transactions involving the “acquisition of control” of a Canadian business by a non-Canadian are subject to review and cannot be implemented unless the responsible minister or ministers under the Investment Canada Act is satisfied or deemed to be satisfied that the transaction is likely to be of “net benefit” to Canada (a “reviewable transaction”). The transactions contemplated by the arrangement agreement constitute a reviewable transaction under the Investment Canada Act. Pursuant to the arrangement agreement, Chord submitted its application for review with the Foreign Investment Review and Economic Security Branch of Innovation, Science and Economic Development Canada on March 6, 2024. As of the date of this proxy statement, the review of the transactions contemplated by the arrangement agreement under the Investment Canada Act is ongoing, and the Investment Canada Act approval required pursuant to the arrangement agreement has not been obtained.

Canadian Antitrust Approval

Part IX of the Competition Act (Canada) (“Competition Act”) requires that parties to certain prescribed classes of transactions provide notifications to the Commissioner of Competition (the “commissioner”) where the applicable thresholds set out in Sections 109 and 110 of the Competition Act are exceeded and no exemption applies (“notifiable transactions”). Subject to certain limited exceptions, a notifiable transaction cannot be completed until the parties to the transaction have each submitted the information prescribed pursuant to Subsection 114(1) of the Competition Act (a “notification”) to the commissioner and the applicable waiting period has expired or has been terminated or waived by the commissioner. The parties have jointly determined that none of the transactions contemplated by the arrangement agreement constitute a notifiable transaction, and as such no obligation to file notifications arises pursuant to Part IX of the Competition Act.

No Appraisal Rights

Under the DGCL, holders of shares of Chord common stock are not entitled to appraisal rights in connection with the arrangement or any of the matters to be acted on at the special meeting.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

On February 21, 2024, Chord entered into an arrangement agreement with Enerplus, pursuant to which, among other things, the Company has agreed to acquire Enerplus in a stock-and-cash transaction, subject to satisfaction of certain closing conditions. The transaction will be effected by way of a Canadian plan of arrangement under the ABCA. Under the terms of the arrangement agreement, Enerplus shareholders (other than dissenting Enerplus shareholders), will receive 0.10125 shares of Chord common stock and $1.84 in cash, in exchange for each Enerplus common share held at the Closing. The Closing is subject to certain conditions, including, among others, (i) the approval of the arrangement by at least two-thirds of the votes cast by Enerplus shareholders at the Enerplus shareholder meeting, (ii) the approval of the stock issuance proposal by a majority of the votes cast by Chord stockholders at the Chord special meeting, (iii) the approval of the arrangement by the Court on terms consistent with the arrangement agreement and otherwise reasonably satisfactory to the parties, (iv) the authorization for listing of Chord common stock issuable pursuant to the arrangement agreement on the Nasdaq, (v) the absence of any law or order prohibiting the consummation of the arrangement and (vi) the receipt of all requisite regulatory clearances or approvals. These closing conditions may not be fulfilled in a timely manner or at all, and, accordingly, the arrangement may not be completed.

Chord and Enerplus prepare their respective financial statements in accordance with U.S. GAAP. In accordance with FASB ASC 805, Business Combinations, Chord will be treated as the acquirer for accounting purposes and will account for the arrangement as an acquisition of a business.

The unaudited pro forma condensed combined balance sheet at December 31, 2023 was prepared as if the arrangement had occurred on December 31, 2023. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2023 was prepared as if the arrangement had occurred on January 1, 2023. The unaudited pro forma condensed combined financial statements have been derived from the historical consolidated financial statements of the Company and Enerplus.

The unaudited pro forma condensed combined financial statements and underlying pro forma adjustments are based upon currently available information and include certain estimates and assumptions made by the Company’s management; accordingly, actual results could differ materially from the pro forma information. Significant estimates and assumptions include, but are not limited to, the timing of close of the arrangement, the preliminary purchase price allocation and Chord’s stock price at Closing. Management believes that the assumptions used to prepare the unaudited pro forma condensed combined financial statements and accompanying notes provide a reasonable and supportable basis for presenting the significant estimated effects of the arrangement. The following unaudited pro forma condensed combined statement of operations does not purport to represent what the Company’s results of operations would have been if the arrangement had occurred on January 1, 2023. The unaudited pro forma condensed combined balance sheet does not purport to represent what the Company’s financial position would have been if the arrangement had occurred on December 31, 2023. The unaudited pro forma condensed combined financial statements should be read together with the Company’s audited historical consolidated financial statements and related notes included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on February 26, 2024, and Enerplus’ audited historical consolidated financial statements and related notes filed with SEDAR+ on February 21, 2024 and included in its Annual Report on Form 40-F for the fiscal year ended December 31, 2023, filed with the SEC on February 21, 2024.

The unaudited pro forma condensed combined financial statements have been prepared in accordance with Article 11 as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses,” using assumptions set forth in the notes herein. Article 11 permits presentation of reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). The Company has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial statements.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

1. Basis of Presentation

The unaudited pro forma condensed combined financial statements have been prepared in accordance with Article 11 using assumptions set forth in the notes herein. Article 11 permits presentation of reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur, otherwise known as Management’s Adjustments. The Company has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial statements.

On February 21, 2024, the Company entered into the arrangement agreement with Enerplus, pursuant to which, among other things, the Company has agreed to acquire Enerplus in a stock-and-cash transaction, subject to satisfaction of certain closing conditions. The transaction will be effected by way of a plan of arrangement under the ABCA. Under the terms of the arrangement agreement, Enerplus shareholders (other than dissenting Enerplus shareholders) will receive 0.10125 shares of Chord common stock and $1.84 in cash in exchange for each Enerplus common share held at the Closing. The arrangement will be accounted for using the acquisition method of accounting using the accounting guidance in FASB ASC 805, Business Combinations, with Chord treated as the accounting acquirer. The acquisition method of accounting is dependent upon certain valuations and other studies that have yet to progress to a stage where there is sufficient information for a definitive measure. Accordingly, the pro forma adjustments are preliminary, have been made solely for the purpose of providing pro forma financial information and are subject to revision based on a final determination of fair value as of the closing date of the arrangement. Differences between preliminary estimates and the final allocation of the consideration to be paid may have a material impact on the accompanying unaudited pro forma condensed combined financial statements.

The unaudited pro forma condensed combined balance sheet at December 31, 2023 was prepared as if the arrangement had occurred on December 31, 2023. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2023 was prepared as if the arrangement had occurred on January 1, 2023. The unaudited pro forma condensed combined financial statements have been derived from the historical consolidated financial statements of the Company and Enerplus.

The unaudited pro forma condensed combined financial statements and underlying pro forma adjustments are based upon currently available information and include certain estimates and assumptions made by management; accordingly, actual results could differ materially from the pro forma information. Management believes the assumptions provide a reasonable and supportable basis for presenting the estimated significant effects of the transactions described above. These unaudited pro forma condensed combined financial statements are provided for illustrative purposes only and may or may not provide an indication of results in the future.

3. Arrangement Preliminary Acquisition Accounting and Pro Forma Adjustments and Assumptions

Balance Sheet

The unaudited pro forma condensed combined balance sheet at December 31, 2023 reflects the following adjustments:

(a) As the accounting acquirer, Chord will account for the arrangement using the acquisition method of accounting for business combinations in accordance with ASC 805. Chord’s allocation of the preliminary estimated purchase price with respect to the arrangement is based on estimates of, and assumptions related to, the fair value of assets to be acquired and liabilities to be assumed as of December 31, 2023, using currently available information. Because the unaudited pro forma condensed combined financial statements have been prepared based on these preliminary estimates, the final purchase price allocation and the resulting effect on the financial position and results of operations of the combined company may be materially different from the pro forma amounts included herein. Chord expects to finalize the purchase price allocation as soon as reasonably practical after completing the arrangement, which will not extend beyond the one-year measurement period provided under ASC 805.

The preliminary purchase price allocation is subject to change due to several factors, including, but not limiting to, the following:

• Changes in the estimated fair value of the Chord common stock consideration issued to Enerplus shareholders, based on the Chord common stock closing price and the number of Enerplus common shares outstanding and the number of validly exercised dissent rights by the Enerplus shareholders;

• Changes in the estimated fair value of Enerplus’ identifiable assets acquired and liabilities assumed as of the closing date of the arrangement, which could result from changes in oil and natural gas commodity prices, reserve estimates, discount rates and other factors;

• The tax basis of Enerplus’ assets and liabilities as of the closing date of the arrangement; and

• The factors described in the section entitled “Risk Factors” beginning on page 43.

34

The tables below represent the preliminary value of the consideration and its allocation to the net assets acquired (in thousands, except exchange ratio and per share amounts).

	Enerplus Shares Outstanding(1)		Exchange Ratio			Chord Converted Shares		Per Share Price(2)		Purchase Price Consideration
Legacy Enerplus common shares issued and outstanding		204,246		x 0.10125	=		20,680	$	164.10	$	3,393,573
Plus: Cash consideration per eligible share of legacy Enerplus common shares issued and outstanding		204,246							1.84		375,813
Plus: Cash consideration to settle legacy Enerplus awards											92,775
Plus: Cash consideration to payoff legacy Enerplus debt contemporaneously with close											65,741
Plus: Cash consideration to pay a retention bonus to legacy Enerplus employees											6,000
Preliminary arrangement consideration										$	3,933,902

(1) The Enerplus shares outstanding consist of Enerplus common shares issued and outstanding as of March 1, 2024.

(2) The per share price applied to Enerplus common shares issued and outstanding reflects the closing price per share of Chord common stock as of March 14, 2024. The per share price attributable to the cash consideration is the cash consideration per share amount as stipulated in the arrangement agreement.

Accrued liabilities		166,128
Current portion of long-term debt		80,600
Current operating lease liabilities		12,087
Long-term debt		34,800
Deferred tax liabilities		937,817
Asset retirement obligations		93,018
Operating lease liabilities		14,333
Total liabilities assumed		1,576,659
Net Assets Acquired	$	3,140,316
Goodwill Acquired		793,586
Purchase price consideration	$	3,933,902

The final value of the consideration will be determined based on the actual number of Enerplus common shares issued and outstanding and the market price of Chord common stock at the Closing. A 20% change in the closing price of Chord common stock, as compared to the March 14, 2024 closing price of $164.10, would increase or decrease the consideration by approximately $678.7 million, assuming all other factors are held constant. Chord anticipates that a change in the closing price of Chord common stock will primarily impact the value of oil and gas properties and could result in the recognition of goodwill or a bargain purchase gain in the purchase price allocation as of the closing date of the arrangement.

(b) Represents the incremental borrowings of $155.6 million used to finance the Closing using Chord’s existing revolving credit facility.

The amount of incremental borrowings reflected in the unaudited pro forma condensed combined financial statements represents the total cash necessary to effectuate the arrangement less the sum of (i) the historical cash balance at Chord as of December 31, 2023 and (ii) the historical cash balance at Enerplus as of December 31, 2023. Depending upon the actual cash balances at Chord and Enerplus on the closing date of the arrangement, the actual amount of cash that Chord borrows will differ from the amount presented in the unaudited pro forma condensed combined financial statements as of December 31, 2023.

36

(c) Represents the adjustment to align Enerplus’ historical treatment of capital project prepayments with Chord’s accounting policy. The impact to Oil and gas properties (successful efforts method) is recorded through the preliminary fair value measurement of Enerplus’ oil and gas properties acquired by Chord in tickmark (a).

(d) Represents the adjustment to deferred income taxes to record the acquisition of a net deferred tax liability. This is primarily the result of the purchase price allocated to the acquired oil and gas properties in excess of their acquired tax basis. Additionally, represents the elimination of Enerplus’ Canadian entities’ historical deferred tax asset. The deferred tax adjustment assumes a forecasted blended statutory rate of 24.0%. Because the tax rates used for these unaudited pro forma condensed combined financial statements are an estimate, the blended rate will likely vary from the actual effective rate in periods subsequent to the completion of the arrangement.

(e) Represents the accrual of $40.0 million of estimated transaction costs expected to be incurred by Chord subsequent to December 31, 2023. These transaction costs are preliminary estimates; the final amounts and the resulting effect on Chord’s financial position may differ significantly.

(f) Represents the accrual of $13.1 million in estimated severance costs expected to be incurred by Chord subsequent to December 31, 2023 payable to certain Enerplus officers whom will be terminated pursuant to the arrangement.

(g) Represents the accrual of $4.5 million of estimated employee bonuses payable to Chord employees. These bonuses are preliminary estimates; the final amounts and the resulting effect on Chord’s financial position may differ significantly.

Statement of Operations

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2023 reflects the following adjustments:

(a) Represents the incremental depreciation, depletion and amortization expense related to the assets acquired in the arrangement, which is based on the preliminary purchase price allocation. Depletion was calculated using the unit-of-production method under the successful efforts method of accounting. The depletion expense was adjusted for (i) the revision to the depletion rate reflecting the acquisition costs and the reserve volumes attributable to the acquired oil and gas properties and (ii) the difference in depletion methodology under the successful efforts method of accounting applied by Chord compared to the full cost method of accounting applied by Enerplus. The pro forma depletion rate attributable to the arrangement was $17.53 per barrel of oil equivalent. This adjustment also includes an increase in accretion expense attributable to asset retirement obligations of $2.0 million due to Chord’s higher credit-adjusted risk-free rate relative to Enerplus.

(b) Represents the adjustment to expense certain historical costs originally capitalized by Enerplus under the full cost method of accounting to align with Chord’s accounting policy under the successful efforts method of accounting.

(c) Represents $40.0 million of estimated transaction costs expected to be incurred by Chord subsequent to December 31, 2023. These transaction costs are preliminary estimates; the final amounts and the resulting effect on Chord’s results of operations may differ significantly. These costs are nonrecurring and will not affect Chord’s statement of operations beyond 12 months after the Closing.

(d) Represents $13.1 million in estimated severance costs expected to be incurred by Chord subsequent to December 31, 2023 payable to certain Enerplus officers whom will be terminated pursuant to the arrangement. These costs are nonrecurring and will not affect Chord’s statement of operations beyond 12 months after the Closing.

(e) Represents $4.5 million of estimated employee bonuses payable to Chord employees. These bonuses are preliminary estimates; the final amounts and the remaining effect on Chord’s results of operations may differ significantly. These costs are nonrecurring and will not affect Chord’s statement of operations beyond 12 months after the Closing.

37

(f) Represents the net increase to interest expense resulting from the (i) elimination of interest expense on Enerplus’ bank credit facilities, (ii) incremental interest expense for the amortization of the fair value adjustment to Enerplus’ senior notes assumed by Chord, (iii) reduction of interest expense to align with Chord’s capitalized interest accounting policy, and (iv) incremental interest expense for borrowings on Chord’s existing credit facility to finance the Closing, as follows:

	Year Ended December 31, 2023 (In thousands)
Elimination of interest expense on Enerplus’ bank credit facilities	$	10,078
Incremental interest expense for amortization of remeasurement of legacy Enerplus’ senior notes		(3,237	)
Reduction of interest expense related to capitalized interest to align with Chord’s accounting policy		2,168
Incremental interest expense for borrowings on Chord’s revolving credit facility		(11,048	)
Net transaction accounting adjustments to interest expense	$	(2,039	)

A 0.125% change in the variable interest rate of Chord’s revolving credit facility or a $10 million change in the amount financed would increase or decrease interest expense presented in the unaudited pro forma condensed combined statement of operations for the year ended December 31, 2023 by $0.2 million and $0.7 million, respectively.

(g) Represents the estimated income tax impact of the pro forma adjustments from the arrangement at the estimated blended federal and state statutory rate of approximately 24.0% for the year ended December 31, 2023. Because the tax rates used for these unaudited pro forma condensed combined financial statements are an estimate, the blended rate will likely vary from the actual effective rate in periods subsequent to the completion of the arrangement.

(h) The table below represents the calculation of the weighted average shares outstanding and earnings per share included in the unaudited pro forma condensed combined statement of operations for the year ended December 31, 2023. As the arrangement is being reflected in the unaudited pro forma condensed combined statement of operations for the year ended December 31, 2023 as if it had occurred on January 1, 2023, the calculation of weighted average shares outstanding for basic and diluted earnings per share assumes that the shares issuable related to the arrangement have been outstanding for the entire year.

	Year Ended December 31, 2023
	(In thousands, except per share data)
Pro forma net income	$	1,208,066
Basic shares:
Chord shares outstanding (weighted average per statement of operations)		41,490
Chord shares issued in exchange for legacy Enerplus shares as part of consideration transferred		20,680
Pro forma weighted average common shares outstanding, basic		62,170
Diluted shares:

4. Supplemental Pro Forma Crude Oil, Natural Gas and Natural Gas Liquids Reserves Information

The following tables present the estimated pro forma combined net proved developed and undeveloped crude oil, natural gas and natural gas liquids (“NGLs”) reserves prepared as of December 31, 2023, along with a summary of changes in the quantities of net remaining proved reserves during the year ended December 31, 2023. The pro forma combined standardized measure of discounted future net cash flows relating to proved reserves as of December 31, 2023, as well as changes to the standardized measure for the year ended December 31, 2023, are also presented.

The pro forma combined reserve, production and standardized measure have been prepared in accordance with FASB ASC Topic 932 – Extractive Activities – Oil and Gas. Further, this pro forma combined reserves, production and standardized measure information gives effect to the arrangement as if it had been completed on January 1, 2023; however, the proved reserves and standardized measures presented below represent the respective estimates made as of December 31, 2023, by the Company and Enerplus while they were separate companies. These estimates have not been updated for changes in development plans or other factors, which have occurred or may occur subsequent to December 31, 2023, or subsequent to the completion of the arrangement. This pro forma information has been prepared for illustrative purposes and is not intended to be a projection of future results of the combined company. With respect to the disclosures below, the amounts were determined by referencing the “Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Natural Gas Reserves” reported in the Company’s Annual Report on Form 10-K and the “Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Crude Oil and Natural Gas Reserves Quantities” reported in Enerplus’ Annual Report on Form 40-F for the year ended December 31, 2023; an explanation of the underlying methodology applied, as required by SEC regulations, can be found within the Annual Report on Form 10-K for the Company and the Annual Report on Form 40-F for Enerplus.

RISK FACTORS

In deciding how to vote, Chord stockholders should carefully consider the following risk factors and all of the information contained in or incorporated by reference herein, including, but not limited to, the matters addressed in “Cautionary Statement Regarding Forward-Looking Statements” as well as Chord’ and Enerplus’ other filings with the SEC incorporated herein by reference. Please see “Where You Can Find More Information.”

Risk Factors Relating to the Arrangement

Chord stockholders and Enerplus shareholders, in each case as of immediately prior to the arrangement, will have significantly reduced ownership in the combined company.

Chord anticipates issuing 0.10125 shares of Chord common stock to Enerplus shareholders in exchange for each Enerplus common share (other than Enerplus common shares held by dissenting Enerplus shareholders), pursuant to the arrangement agreement. Following the completion of the arrangement, it is anticipated that persons who were shareholders of Chord and Enerplus immediately prior to the arrangement will own approximately 67% and 33% of the combined company, respectively, on a fully diluted basis. As a result, Chord’s current shareholders and Enerplus’ current shareholders will have less influence on the policies of the combined company than they currently have on Chord’s policies and Enerplus’ policies, respectively.

The exchange ratio will not be adjusted in the event of any change in either Chord’s or Enerplus’ share price.

Upon completion of the arrangement, each Enerplus common share (other than Enerplus common shares held by dissenting Enerplus shareholders) will be converted into the right to receive 0.10125 of a share of Chord common stock and $1.84 in cash. This exchange ratio was generally fixed in the arrangement agreement and will not be adjusted to reflect changes in the market price of either Enerplus common shares or Chord common stock before the arrangement is completed. Stock price changes may result from a variety of factors (many of which are beyond Chord’s and Enerplus’ control), including the following:

• changes in Chord’s and Enerplus’ respective businesses, operations and prospects;

• investor behavior and strategies, including market assessments of the likelihood that the arrangement will be completed, including related considerations regarding court approval and regulatory clearance or approval, if any, of the arrangement;

• interest rates, general market and economic conditions and other factors generally affecting the price of Chord’s and Enerplus’ shares; and

• foreign, federal, state, provincial and local legislation, governmental regulation and legal developments in the businesses in which Chord and Enerplus operate.

The price of Chord common stock at the completion of the arrangement will vary from its price on the date the arrangement agreement was executed, the date of this proxy statement, the date of the special meeting and the effective date. As a result, the market value represented by the exchange ratio will also vary. For example, based on the range of closing prices of Chord common stock during the period from February 20, 2024, the trading day before the date of the public announcement of the arrangement, through April 5, 2024, the latest practicable date before the date of this proxy statement, the exchange ratio represented a market value ranging from a low of $17.71 to a high of $20.55 for each Enerplus common share.

The arrangement is subject to a number of conditions which may delay the arrangement and could result in additional expenditures of money and resources or reduce the anticipated benefits, or result in termination of the arrangement agreement and Chord having to pay a termination fee.

Chord’s obligations and the obligations of Enerplus to consummate the arrangement are subject to the satisfaction (or waiver by all parties, to the extent permissible under applicable laws) of a number of conditions

43

described in the arrangement agreement, including the approval by Chord stockholders of the stock issuance proposal, the approval and adoption of the arrangement resolution by the Enerplus shareholders, the approval of the arrangement by the Court of King’s Bench of Alberta on terms consistent with the arrangement agreement and otherwise reasonably satisfactory to the parties and receipt of certain regulatory clearances and approvals. Many of the conditions to completion of the arrangement are not within Chord’s control and Chord cannot predict when, or if, these conditions will be satisfied. If any of these conditions are not satisfied or waived prior to the termination date, it is possible that the arrangement agreement may be terminated. The arrangement agreement provides that, upon termination of the arrangement agreement under certain circumstances, Chord or Enerplus would be required to pay the other party a termination fee of $240 million and $127 million, respectively. See “The Arrangement Agreement — Conditions to Completion of the Arrangement.”

Although the parties have agreed to use reasonable best efforts, subject to certain limitations, to complete the arrangement promptly, these and other conditions may fail to be satisfied. In addition, completion of the arrangement may take longer and could cost more than we expect. The requirements for obtaining the required Regulatory Approvals and clearances could delay the completion of the arrangement for a significant period of time or prevent them from occurring. Any delay in completing the arrangement may adversely affect the synergies and other benefits that Chord expects to achieve if the arrangement and the integration of businesses were to be completed within the expected timeframe.

If a governmental authority asserts objections to the arrangement, Chord may be unable to complete the arrangement or, in order to do so, Chord or Enerplus may be required to comply with material restrictions or satisfy material conditions.

Closing is subject to the condition that there is no order preventing the consummation of the arrangement and no law applicable to the arrangement that makes consummation of the arrangement illegal. Pursuant to the arrangement agreement, Chord and Enerplus have agreed to use reasonable best efforts, subject to certain limitations, to complete the arrangement promptly.

There can be no assurance as to the cost, scope or impact of the actions that may be required to address any governmental authority objections to the arrangement. If Chord or Enerplus takes such actions, it may be detrimental to them or to the combined company following the consummation of the arrangement. Furthermore, these actions may have the effect of delaying or preventing consummation of the arrangement or imposing additional costs on or limiting the revenue or cash available for distribution of the combined company following the consummation of the arrangement. There are also limitations in the arrangement agreement on the actions Chord is required to take in order to address any governmental authority objections to the arrangements; so, depending on the nature of the governmental authority objections to the arrangement, Chord may decline to agree to take such actions resulting in the failure of the arrangement to be completed.

Chord or Enerplus may waive one or more of the closing conditions without re-soliciting approval by Chord stockholders.

Chord or Enerplus may determine to waive, in whole or part, one or more of the conditions to closing prior to Chord or Enerplus, as the case may be, being obligated to consummate the arrangement. Chord expects to evaluate the materiality of any proposed waiver and its effect on Chord stockholders in light of the facts and circumstances at the time, to determine whether any amendment of this proxy statement or any re-solicitation of proxies is required in light of such waiver. Any determination whether to waive any condition to closing or to re-solicit stockholder approval or amending or supplementing this proxy statement as a result of a waiver will be made by Chord at the time of such waiver based on the facts and circumstances as they exist at that time.

44

Uncertainties associated with the arrangement may cause a loss of management personnel and other key employees of Chord and Enerplus, which could adversely affect the future business and operations of the combined company following the arrangement.

Chord and Enerplus are dependent on the experience and industry knowledge of their respective officers and other key employees to execute their business plans. The combined company’s success after the arrangement will depend in part upon its ability to retain key management personnel and other key employees of both Chord and Enerplus. Current and prospective employees of Chord and Enerplus may experience uncertainty about their roles within the combined company following the arrangement or other concerns regarding the timing and completion of the arrangement or the operations of the combined company following the arrangement, any of which may have an adverse effect on the ability of Chord and Enerplus to retain or attract key management and other key personnel. If Chord is unable to retain personnel, including key management, who are critical to the future operations of Chord, Chord could face disruptions in its operations, loss of existing customers, loss of key information, expertise or know-how and unanticipated additional recruitment and training costs. In addition, the loss of key personnel could diminish the anticipated benefits of the arrangement. No assurance can be given that the combined company, following the arrangement, will be able to retain or attract key management personnel and other key employees to the same extent that Chord and Enerplus have previously been able to retain or attract their own employees.

The business relationships of Chord and Enerplus, as applicable, may be subject to disruption due to uncertainty associated with the arrangement, which could have a material adverse effect on the results of operations, cash flows and financial position of Chord pending and following the arrangement.

Parties with which Chord and Enerplus, as applicable, does business may experience uncertainty associated with the arrangement, including with respect to current or future business relationships with Chord following the arrangement. Chord and Enerplus’ business relationships may be subject to disruption as customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners may attempt to delay or defer entering into new business relationships, negotiate changes in existing business relationships or consider entering into business relationships with parties other than Chord or Enerplus, as applicable, following the arrangement. These disruptions could have a material and adverse effect on the results of operations, cash flows and financial position of Chord, regardless of whether the arrangement is completed, as well as a material and adverse effect on Chord’s ability to realize the expected synergies and other benefits of the arrangement. The risk, and adverse effect, of any disruption could be exacerbated by a delay in completion of the arrangement or termination of the arrangement agreement.

The arrangement agreement subjects Chord to restrictions on its business activities prior to the Closing, limits its ability to pursue alternatives to the arrangement and may discourage other companies from making a favorable alternative transaction proposal.

The arrangement agreement subjects Chord to restrictions on its business activities prior to the Closing. The arrangement agreement obligates Chord to generally conduct its businesses in the ordinary course until the Closing and to, among other things, use its reasonable best efforts to (i) preserve substantially intact its present business organization, goodwill and assets, (ii) keep available the services of its current officers and employees and (iii) preserve its existing relationships with governmental entities and significant customers, suppliers, licensors, licensees, distributors, lessors and others having significant business dealings with Chord. These restrictions could prevent Chord from pursuing certain business opportunities that arise prior to the Closing and are outside the ordinary course of business. See “The Arrangement Agreement — Conduct of Business” for additional details.

Chord is subject to customary restrictions on its ability to solicit alternative acquisition proposals and to provide information to, or engage in discussions with, third parties regarding such proposals, except that Chord is permitted in limited circumstances prior to receiving approval from Chord stockholders of the issuance of new

45

shares of Chord common stock in the arrangement to provide information to, and engage in discussions with, a party which has made an unsolicited acquisition proposal that the Chord board of directors has determined constitutes or would reasonably be expected to constitute a superior proposal. Furthermore, in limited circumstances prior to receiving stockholder approval, the Chord board of directors may effect a change of its recommendation in response to an applicable intervening event if the Chord board of directors determines in good faith that a failure to effect a change in recommendation would be reasonably likely to be inconsistent with the Chord board of director’s fiduciary duties.

Chord directors and executive officers have interests in the arrangement that may be different from, or in addition to, the interests of the Chord stockholders generally.

In considering the recommendation of the Chord board of directors that Chord stockholders vote in favor of each of the proposals, Chord stockholders should be aware of and take into account the fact that certain Chord directors and executive officers have interests in the arrangement that may be different from, or in addition to, the interests of Chord stockholders generally. See “The Arrangement — Interests of Chord Directors and Executive Officers in the Arrangement” for a more detailed description of these interests. The Chord board of directors was aware of and carefully considered these interests, among other matters, in evaluating the terms and structure, and overseeing the negotiation, of the arrangement, in approving the arrangement agreement and the arrangement, and in recommending that the Chord stockholders adopt the arrangement agreement and the charter amendment. Such interests include that certain current directors and executive officers of Chord are expected to continue as directors and executive officers of Chord following the consummation of the arrangement.

Chord does not currently control Enerplus and its subsidiaries.

Chord will not control Enerplus and its subsidiaries until completion of the arrangement and the business and results of operations of Enerplus may be adversely affected by events that are outside of Chord’s control during the intervening period. The performance of Enerplus may be influenced by, among other factors, economic downturns, changes in commodity prices, political instability in the countries in which Enerplus operates, changes in applicable laws, expropriation, increased environmental regulation, volatility in the financial markets, unfavorable regulatory decisions, litigation, rising costs, civic and labor unrest, disagreements with joint venture partners, delays in ongoing exploration and development projects and other factors beyond Chord’s control. As a result of any one or more of these factors, among others, the operations and financial performance of Enerplus may be negatively affected, which may adversely affect the future financial results of the combined company.

Failure to complete the arrangement could negatively impact Chord’s stock price and have a material adverse effect on its results of operations, cash flows and financial position.

If the arrangement is not completed for any reason, including as a result of failure to obtain all requisite Regulatory Approvals or if the Chord stockholders or Enerplus shareholders fail to approve the stock issuance proposal and the arrangement resolution, respectively, the ongoing businesses of Chord may be materially adversely affected and, without realizing any of the benefits of having completed the arrangement, Chord would be subject to a number of risks, including the following:

• Chord may experience negative reactions from the financial markets, including negative impacts on its stock price;

• Chord and its subsidiaries may experience negative reactions from their customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners;

• Chord will still be required to pay certain significant costs relating to the arrangement, such as legal, accounting, financial advisor and printing fees;

• Chord may be required to pay a termination fee as required by the arrangement agreement;

46

• the arrangement agreement places certain restrictions on the conduct of the Chord’s business prior to the completion of the arrangement agreement, which may delay or prevent Chord from undertaking business opportunities that, absent the arrangement agreement, may have been pursued;

• matters relating to the arrangement (including integration planning) require substantial commitments of time and resources by Chord’s management, which may have resulted in the distraction of Chord’s management from ongoing business operations and pursuing other opportunities that could have been beneficial to the companies; and

• litigation related to any failure to complete the arrangement or related to any enforcement proceeding commenced against Chord to perform its obligations pursuant to the arrangement agreement.

If the arrangement is not completed, the risks described above may materialize and they may have a material adverse effect on Chord’s results of operations, cash flows, financial position and stock price.

Completion of the arrangement may trigger change in control or other provisions in certain agreements to which Chord or Enerplus is a party.

The completion of the arrangement may trigger change in control or other provisions in certain agreements to which Chord or Enerplus is a party. If Chord and Enerplus are unable to negotiate waivers of those provisions, the counterparties may exercise their rights and remedies under such agreements, potentially terminating such agreements, or seeking monetary damages. Even if Chord and Enerplus are able to negotiate waivers, the counterparties may require a fee for such waivers or seek to renegotiate such agreements on terms less favorable to Chord or Enerplus.

Chord and Enerplus are expected to incur significant transaction costs in connection with the arrangement, which may be in excess of those anticipated by them.

Chord and Enerplus have incurred and are expected to continue to incur a number of non-recurring costs associated with negotiating and completing the arrangement, combining the operations of the two companies and achieving desired synergies. These costs have been, and will continue to be, substantial and, in many cases, will be borne by Chord whether or not the arrangement is completed. A substantial majority of non-recurring expenses will consist of transaction costs and include, among others, fees paid to financial, legal, accounting and other advisors, employee retention, severance and benefit costs, and filing fees. Chord will also incur costs related to formulating and implementing integration plans, including facilities and systems consolidation costs and other employment-related costs. Chord and Enerplus will continue to assess the magnitude of these costs, and additional unanticipated costs may be incurred in connection with the arrangement and the integration of the two companies’ businesses. While Chord and Enerplus have assumed that a certain level of expenses would be incurred, there are many factors beyond their control that could affect the total amount or the timing of the expenses. The elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, may not offset integration-related costs and achieve a net benefit in the near term, or at all. The costs described above and any unanticipated costs and expenses, many of which will be borne by Chord even if the arrangement is not completed, could have an adverse effect on Chord’s financial condition and operating results.

Litigation relating to the arrangement could result in an injunction preventing the completion of the arrangement and/or substantial costs to Chord and Enerplus.

Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into acquisitions, mergers or other business combination agreements. Even if such a lawsuit is without merit, defending against these claims can result in substantial costs and divert management time and resources. An adverse judgment could result in monetary damages, which could have a negative impact on Chord’s and Enerplus’ respective liquidity and financial condition.

47

Lawsuits that may be brought against Chord, Enerplus or their respective directors which could seek, among other things, injunctive relief or other equitable relief, including a request to rescind parts of the arrangement agreement already implemented and to otherwise enjoin the parties from consummating the arrangement. One of the conditions to the Closing is that no injunction by any court or other tribunal of competent jurisdiction has been entered and continues to be in effect and no law has been adopted or is effective, in either case that prohibits or makes illegal the Closing. Consequently, if a plaintiff is successful in obtaining an injunction prohibiting completion of the arrangement, that injunction may delay or prevent the arrangement from being completed within the expected timeframe or at all, which may adversely affect Chord’s and Enerplus’ respective business, financial position, results of operations and cash flows.

There can be no assurance that any of the defendants will be successful in the outcome of any pending or any potential future lawsuits. The defense or settlement of any lawsuit or claim that remains unresolved at the time the arrangement is completed may adversely affect Chord’s or Enerplus’ business, financial condition, results of operations and cash flows.

Enerplus may have liabilities that are not known to Chord.

Enerplus may have liabilities that Chord failed, or was unable, to discover in the course of performing its due diligence investigations. Other than publicly available information, all historical information relating to Enerplus has been provided in exclusive reliance on the information made available to us by Enerplus and its representatives. Through the completion of the arrangement, Enerplus continues to be obligated to file its current and annual reports with the SEC. Additionally, pursuant to the arrangement agreement, during the period from the date of the arrangement agreement until the earlier of the effective time and the termination thereof, Enerplus is required to notify us in writing of any material change in the business, operations, results of operations, properties, assets, liabilities (whether absolute, accrued, contingent or otherwise), or financial condition of it and its subsidiaries on a consolidated basis or any change in any representation or warranty it has provided in the arrangement agreement that may render any representation or warranty misleading or untrue in any material respect. Chord may learn additional information about the other party that materially adversely affects it, such as unknown or contingent liabilities and liabilities related to compliance with applicable laws. As a result of these factors, the combined company may incur additional costs and expenses and may be forced to later write-down or write-off assets, restructure operations or incur impairment or other charges that could result in the combined company reporting losses. Even if Chord’s due diligence has identified certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with its preliminary risk analysis. If any of these risks materialize, this could have a material adverse effect on the combined company’s financial condition and results of operations and could contribute to negative market perceptions about Chord common stock.

The combined company may record goodwill and other intangible assets that could become impaired and result in material non-cash charges to the results of operations of the combined company in the future.

The combined company will account for the arrangement as an acquisition of a business in accordance with U.S. GAAP. Under the acquisition method of accounting, the assets and liabilities of Enerplus and its subsidiaries will be recorded, as of completion, at their respective fair values and added to those of Chord. The reported financial condition and results of operations of Chord for periods after completion of the arrangement will reflect Enerplus’ balances and results after completion of the arrangement, but will not be restated retroactively to reflect the historical financial position or results of operations of Enerplus and its subsidiaries for periods prior to the arrangement.

Under the acquisition method of accounting, the total purchase price will be allocated to Enerplus’ identifiable tangible and intangible assets acquired and liabilities assumed based on their respective fair values as of the completion date of the arrangement, with any excess purchase price over those fair values recorded as goodwill. To the extent the value of goodwill or intangibles, if any, becomes impaired in the future, the combined company

48

may be required to incur material non-cash charges relating to such impairment. The combined company’s operating results may be significantly impacted from both the impairment and the underlying trends in the business that triggered the impairment.

Potential payments to Enerplus shareholders who exercise dissent rights could have an adverse effect on the combined company’s financial condition.

Enerplus shareholders have the right to exercise dissent rights and demand payment equal to the fair value of their Enerplus common shares. If dissent rights are properly exercised in respect of a significant number of Enerplus common shares, a substantial payment may be required to be made to such Enerplus shareholders, which could have an adverse effect on the combined company’s financial condition and cash flows. Such payment, however, shall be reduced by the portion of the additional dividend that an Enerplus shareholder has received (or is entitled to receive), if any.

Risk Factors Relating to the Combined Company Following the Arrangement

The combined company may be unable to integrate the businesses of Chord and Enerplus successfully or realize the anticipated benefits of the arrangement.

The arrangement involves the combination of two companies that currently operate as independent public companies. The combination of two independent businesses is complex, costly and time consuming, and each of Chord and Enerplus will be required to devote significant management attention and resources to integrating the business practices and operations of Enerplus into Chord. Potential difficulties that Chord and Enerplus may encounter as part of the integration process include the following:

• the inability to successfully combine the business of Chord and Enerplus in a manner that permits the combined company to achieve, on a timely basis, or at all, the enhanced revenue opportunities and cost savings and other benefits anticipated to result from the arrangement;

• complexities associated with managing the combined businesses, including difficulty addressing possible differences in operational philosophies and the challenge of integrating complex systems, technology, networks and other assets of each of the companies in a seamless manner that minimizes any adverse impact on customers, suppliers, employees and other constituencies;

• the assumption of contractual obligations with less favorable or more restrictive terms; and

• potential unknown liabilities and unforeseen increased expenses or delays associated with the arrangement.

In addition, Chord and Enerplus have operated and, until the completion of the arrangement, will continue to operate, independently. It is possible that the integration process could result in:

• diversion of the attention of each company’s management; and

• the disruption of, or the loss of momentum in, each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies.

Any of these issues could adversely affect each company’s ability to maintain relationships with customers, suppliers, employees and other constituencies or achieve the anticipated benefits of the arrangement, or could reduce each company’s earnings or otherwise adversely affect the business and financial results of the combined company following the arrangement.

Declaration, payment and amounts of dividends, if any, distributed to stockholders of the combined company will be uncertain.

Although Chord has paid cash dividends on Chord common stock in the past, Chord stockholders have no contractual or other legal right to dividends that have not been declared and Chord may determine not to declare

49

dividends in the future or may reduce the amount of dividends in the future. The combined company board, therefore, may also determine not to declare dividends in the future or may reduce the amount of dividends paid in the future. Any payment of future dividends will be at the discretion of the combined company board and will depend on combined company’s results of operations, financial condition, cash requirements, future prospects and other considerations that the combined company board deems relevant, including, but not limited to:

• the combined company may not have enough cash to pay such dividends or to repurchase shares due to its cash requirements, capital spending plans, cash flow or financial position;

• decisions on whether, when and in which amounts to make any future distributions will remain at all times entirely at the discretion of the combined company board, which could change its dividend practices at any time and for any reason;

• the combined company’s desire to maintain or improve the credit ratings on its debt;

• the amount of dividends that the combined company may distribute to its stockholders or shares that it may repurchase from its stockholders is subject to restrictions under Delaware law; and

• the agreements governing the combined company’s indebtedness.

The trading price and volume of the combined company common stock may be volatile following the arrangement.

The trading price and volume of the combined company common stock may be volatile following completion of the arrangement. The stock markets in general have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of the combined company common stock. As a result, you may suffer a loss on your investment. Many factors may impair the market for the combined company common stock and the ability of investors to sell shares at an attractive price, and could also cause the market price and demand for the combined company common stock to fluctuate substantially, which may negatively affect the price and liquidity of the combined company common stock. Many of these factors and conditions are beyond the control of the combined company or the combined company stockholders.

The market price of Chord common stock may decline if large amounts of Chord common stock are sold following the arrangement and may be affected by factors different from those that historically have affected or currently affect the market price of Chord common stock.

The market price of Chord common stock may fluctuate significantly following completion of the arrangement and holders of Chord common stock could lose some or all of the value of their investment. If the arrangement is consummated, Chord will issue shares of Chord common stock to former Enerplus shareholders. The arrangement agreement contains no restrictions on the ability of former Enerplus shareholders to sell or otherwise dispose of such shares following completion of the arrangement. Former Enerplus shareholders may decide not to hold the shares of Chord common stock that they receive in the arrangement, and Chord’s historic stockholders may decide to reduce their investment in Chord as a result of the changes to Chord’s investment profile as a result of the arrangement. These sales of Chord common stock (or the perception that these sales may occur) could have the effect of depressing the market price for Chord common stock. In addition, Chord’s financial position after completion of the arrangement may differ from its financial position before the completion of the arrangement, and the results of Chord’s operations and cash flows after the completion of the arrangement may be affected by factors different from those currently affecting its financial position or results of operations and cash flows, all of which could adversely affect the market price of Chord common stock. Accordingly, the market price and performance of Chord common stock is likely to be different from the performance of Chord common stock prior to the arrangement. Furthermore, the stock market has experienced significant price and volume fluctuations in recent times which, if they continue to occur, could have a material adverse effect on the market for, or liquidity of, Chord common stock, regardless of our actual operating performance.

50

Enerplus’ public filings are subject to Canadian disclosure standards, which differ from SEC disclosure requirements.

Chord’s reserve estimates have been prepared in accordance with FASB ASC Topic 932 – Extractive Activities – Oil and Natural Gas under U.S. GAAP and subpart 1200 of Regulation S-K promulgated by the SEC (the “U.S. Standards”). Chord has not been involved in the preparation of Enerplus’ historical oil and natural gas reserves estimates. Enerplus’ historical oil and natural gas reserves estimates were prepared in accordance with the standards set forth in the COGE Handbook and the reserves definitions contained in NI 51-101 and the COGE Handbook, which differ from the requirements of United States securities laws, and certain reserves information are presented in accordance with U.S. Standards. In addition to being a reporting issuer in all provinces of Canada, Enerplus is a registrant with the SEC but is permitted to present disclosure of its reserves information in accordance with the standards set out in the COGE Handbook and the reserves definitions contained in NI 51-101 and the COGE Handbook.

Estimates of reserves made in accordance with NI 51-101 will differ from corresponding U.S. GAAP standardized measure prepared in accordance with U.S. Standards and those differences may be material. For example, the U.S. standards require United States oil and gas reporting companies, in their filings with the SEC, to disclose only proved reserves after the deduction of royalties and production due to others but permits the optional disclosure of probable and possible reserves in accordance with SEC’s definitions. However, NI 51-101 requires Canadian oil and gas reporting companies, in their filings with Canadian securities regulatory authorities, to disclose proved, probable and proved plus probable reserves. In addition, the COGE Handbook and NI 51-101 permit the presentation of reserves estimates on a “gross” basis, representing Enerplus’ working interest share before deduction of royalties, whereas the U.S. Standards require the presentation of net reserve estimates after the deduction of royalties and similar payments. There are also differences in the technical reserves estimation standards applicable under NI 51-101 and, pursuant thereto, the COGE Handbook, and those applicable under the U.S. Standards. NI 51-101 requires that proved undeveloped reserves be reviewed annually for retention or reclassification if development has not proceeded as previously planned, while the U.S. Standards specify a five-year limit after initial booking for the development of proved undeveloped reserves. Finally, the SEC prohibits disclosure of oil and gas resources in SEC filings, including contingent resources, whereas Canadian securities regulatory authorities allow disclosure of oil and gas resources. Resources are different than, and should not be construed as, reserves. The foregoing is not an exhaustive summary of Canadian or U.S. reserves reporting requirements.

The unaudited pro forma condensed combined financial statements and the unaudited prospective financial and operating information prepared by Chord included in this proxy statement are based on a number of preliminary estimates and assumptions and the actual results of operations, cash flows and financial position of the combined company after the arrangement may differ materially.

The unaudited pro forma condensed combined financial statements and the unaudited prospective financial information and operating information in this proxy statement is presented for illustrative purposes only, has been prepared based on available information and certain assumptions and estimates that Chord believes are reasonable, and is not necessarily indicative of what Chord’s actual financial position or results of operations would have been had the pro forma events been completed on the dates indicated. Further, the combined company’s actual results and financial position after the pro forma events occur may differ materially and adversely from the unaudited pro forma information included in this proxy statement. The unaudited pro forma condensed combined financial statements have been prepared with Chord as the accounting acquirer under U.S. GAAP and reflect adjustments based on estimates of, and assumptions related to, the fair value of assets to be acquired and liabilities to be assumed.

The financial forecasts are based on various assumptions that may not be realized.

The financial estimates set forth in the forecasts included under the sections “The Arrangement — Certain Unaudited Prospective Financial and Operating Information” were based on assumptions of, and information

51

available to, Chord management when prepared, and these estimates and assumptions are subject to uncertainties, many of which are beyond Chord’s control and may not be realized. Many factors mentioned in this proxy statement, including the risks outlined in this “Risk Factors” section and the events or circumstances described under “Cautionary Statement Regarding Forward-Looking Statements,” will be important in determining the combined company’s future results. As a result of these contingencies, actual future results may vary materially from Chord’s estimates. In view of these uncertainties, the inclusion of financial estimates in this proxy statement is not and should not be viewed as a representation that the forecasted results will necessarily reflect actual future results.

Chord’s financial estimates were not prepared with a view toward public disclosure, and such financial estimates were not prepared with a view toward compliance with published guidelines of any regulatory or professional body. Further, any forward-looking statement speaks only as of the date on which it is made, and Chord does not undertake any obligation, other than as required by applicable law, to update the financial estimates herein to reflect events or circumstances after the date those financial estimates were prepared or to reflect the occurrence of anticipated or unanticipated events or circumstances. The Forecasted Financial Information (as defined below) included in this proxy statement has been prepared by, and is the responsibility of, Chord management. Neither Chord’s independent registered public accounting firm, PricewaterhouseCoopers LLP (“PricewaterhouseCoopers”), nor any other independent registered public accounting firm, including Enerplus’ independent registered public accounting firm, KPMG LLP (“KPMG”), have audited, reviewed, examined, compiled or applied agreed-upon procedures with respect to the accompanying Forecasted Financial Information and, accordingly, PricewaterhouseCoopers and KPMG do not express an opinion or any other form of assurance with respect thereto nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the prospective financial information. See “The Arrangement — Certain Unaudited Prospective Financial and Operating Information” for more information.

The synergies and other anticipated benefits attributable to the arrangement may vary from expectations.

The combined company may fail to realize the anticipated benefits and synergies expected from the arrangement, which could adversely affect the combined company’s business, financial condition and operating results. The success of the arrangement will depend, in significant part, on the combined company’s ability to successfully integrate the acquired business, grow the revenue of the combined company and realize the anticipated strategic benefits and synergies from the combination. Chord and Enerplus believe that the combination of the companies will provide operational and financial scale, increase free cash flow, and generate meaningful stockholder return. However, achieving these goals requires, among other things, realization of the targeted cost synergies expected from the arrangement. This growth and the anticipated benefits of the transaction may not be realized fully or at all, or may take longer to realize than expected. Actual operating, technological, strategic and revenue opportunities, if achieved at all, may be less significant than expected or may take longer to achieve than anticipated. If the combined company is not able to achieve these objectives and realize the anticipated benefits and synergies expected from the arrangement within the anticipated timing or at all, the combined company’s business, financial condition and operating results may be adversely affected.

The future results of the combined company following the arrangement will suffer if the combined company does not effectively manage its expanded operations.

Following the arrangement, the size of the business of the combined company will increase significantly. The combined company’s future success will depend, in part, upon its ability to manage this expanded business, which will pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. The combined company may also face increased scrutiny from governmental authorities as a result of the significant increase in the size of its business. There can be no assurances that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings, revenue enhancements or other benefits currently anticipated from the arrangement.

52

The arrangement may result in a loss of customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners and may result in the termination of existing contracts.

Following the arrangement, some of the customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners of Chord or Enerplus may terminate or scale back their current or prospective business relationships with the combined company. Some customers may not wish to source a larger percentage of their needs from a single company or may feel that the combined company is too closely allied with one of their competitors. In addition, Chord and Enerplus have contracts with customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners that may require Chord or Enerplus to obtain consents from these other parties in connection with the arrangement, which may not be obtained on favorable terms or at all. If relationships with customers, distributors, suppliers, vendors, landlords, joint venture partners and other business partners are adversely affected by the arrangement, or if the combined company, following the arrangement, loses the benefits of the contracts of Chord or Enerplus, the combined company’s business and financial performance could suffer.

The Chord Certificate of Incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by Chord stockholders, which could limit Chord stockholders’ ability to obtain a favorable judicial forum for disputes with Chord or its directors, officers or other employees.

The Chord Certificate of Incorporation provides that, unless Chord consents in writing to the selection of an alternative forum, and subject to applicable jurisdictional requirements, the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of Chord, (ii) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, employee, agent or stockholder of Chord to Chord or the Chord stockholders, (iii) any action asserting a claim against Chord arising pursuant to any provision of the DGCL, the Chord Certificate of Incorporation or the Chord Bylaws, (iv) any action to interpret, apply, enforce or determine the validity of the Chord Certificate of Incorporation or the Chord Bylaws, (v) any action asserting a claim against Chord governed by the internal affairs doctrine or (vi) any action asserting an “internal corporate claim” as that term is defined in Section 115 of the DGCL, shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the State of Delaware lacks jurisdiction over such actions or proceeding, then another court of the State of Delaware or, if no court of the State of Delaware has jurisdiction, then the United States District Court for the District of Delaware).

Chord’s exclusive forum provision is not intended to apply to claims arising under the Securities Act or the Exchange Act. To the extent the provision could be construed to apply to such claims, there is uncertainty as to whether a court would enforce the forum selection provision with respect to such claims, and in any event, the Chord stockholders would not be deemed to have waived Chord’s compliance with federal securities laws and the rules and regulations thereunder.

Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of Chord is deemed to have received notice of and consented to the foregoing forum selection provision. This provision may limit Chord stockholders’ ability to bring a claim in a judicial forum that they find favorable for disputes with Chord or its directors, officers or other employees, which may discourage such lawsuits. Alternatively, if a court were to find this choice of forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, Chord may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect its business, financial condition, prospects or results of operations.

53

Other Risk Factors Relating to Chord and Enerplus

As a result of entering into the arrangement agreement, Chord’s and Enerplus’ businesses are and will be subject to the risks described above. In addition, Chord and Enerplus are, and following completion of the arrangement, Chord will be, subject to the risks described in Chord’s most recent Annual Report on Form 10-K as updated by subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and Enerplus’ most recent Annual Report on Form 40-F as updated by subsequent Current Reports on Form 6-K, which are filed with the SEC and incorporated by reference into this proxy statement. See “Where You Can Find More Information” for the location of information incorporated by reference into this proxy statement.

THE SPECIAL MEETING

General

This proxy statement is being provided to Chord stockholders as part of a solicitation of proxies by the Chord board of directors for use at the special meeting and at any adjournments or postponements of such special meeting. This proxy statement provides Chord stockholders with important information about the special meeting and should be read carefully in its entirety.

Date, Time and Place of the Special Meeting

The special meeting will be held entirely online at the following website: www.virtualshareholdermeeting.com/CHRD2024SM, on May 14, 2024 at 9:00 AM, Central Time.

Purpose of the Special Meeting

At the special meeting, Chord is asking holders of shares of Chord common stock to vote on the following proposals:

(a) Proposal No. 1 – The Stock Issuance Proposal – to approve the issuance of shares of Chord common stock to Enerplus shareholders in connection with the arrangement;

(b) Proposal No. 2 – The Charter Amendment Proposal – to approve the Charter Amendment to increase the number of authorized shares of Chord common stock from 120,000,000 shares to 240,000,000 shares; and

(c) Proposal No. 3 – The Adjournment Proposal – to approve the adjournment or postponement of the special meeting, if necessary or appropriate, including to solicit additional proxies if there are not sufficient votes to approve the stock issuance proposal, subject to the provisions of the arrangement agreement.

Board Recommendation

After determining that it is advisable and in the best interests of Chord and Chord stockholders to consummate the arrangement as contemplated by the arrangement agreement and adopt the Charter Amendment, conditioned upon the Closing, the Chord board of directors unanimously authorized, approved, and declared advisable the issuance of shares of Chord common stock. Accordingly, the Chord board of directors unanimously recommends that Chord stockholders vote “FOR” each of the proposals to be considered and voted upon at the special meeting.

Chord stockholders can cast separate votes on each proposal.

There are certain risks associated with the arrangement. See the “Risk Factors” section of this proxy statement for more information regarding such risks. Chord stockholders should carefully read this proxy statement in its entirety for more detailed information concerning the arrangement. In particular, Chord stockholders are directed to the arrangement agreement, which is attached as Annex A to this proxy statement.

Record Date; Outstanding Shares; Shares Entitled to Vote

The Chord board of directors has fixed the close of business on April 8, 2024 as the record date for determination of Chord stockholders entitled to notice of, and to vote at, the special meeting. Only Chord stockholders of record holding shares of Chord common stock as of the record date will receive notice of, and be entitled to vote at, the special meeting and any adjournments, postponements or continuations of the special meeting.

55

As of the record date for the special meeting, there were 41,563,092 shares of Chord common stock outstanding and held by approximately 280 Chord stockholders of record. Each Chord stockholder is entitled to one vote at the special meeting for each share of Chord common stock held by that stockholder at the record date. Chord common stock is the only security the holders of which are entitled to notice of, and to vote at, the special meeting.

If you own shares that are registered in the name of someone else, such as a bank, broker or other nominee, you need to direct that organization to vote those shares or vote the shares yourself at the special meeting.

Quorum

The holders of a majority of the shares of Chord common stock issued and outstanding and entitled to vote at the special meeting must be present in person (online) or represented by proxy in order to constitute a quorum for all matters to come before the special meeting. A quorum must be present in order for there to be a vote on each of the proposals to be considered at the special meeting. It is important that Chord stockholders vote promptly so that their shares are counted toward the quorum.

Abstentions are counted for purposes of determining whether a quorum is present at the special meeting. Banks, brokers and other nominees that hold their customers’ shares in street name may not vote their customers’ shares on “non-routine” matters without instructions from their customers. As the stock issuance proposal and the adjournment proposal to be voted upon at the special meeting are considered “non-routine,” such organizations do not have discretion to vote on the stock issuance proposal and the adjournment proposal with a broker non-vote. Therefore, if you fail to provide your bank, broker or other nominee with any instructions regarding how to vote your shares with respect to the stock issuance proposal and the adjournment proposal, your shares will not be considered present at the special meeting, will not be counted for purposes of determining the presence of a quorum and will not be voted on the stock issuance proposal and the adjournment proposal. If you provide instructions to your bank, broker or other nominee which indicate how to vote your shares with respect to one proposal but not with respect to the other proposal, your shares will be considered present at the special meeting and be counted for purposes of determining the presence of a quorum and voted, as instructed, with respect to the appropriate proposal, but will not be voted with respect to the other proposal. Because the charter amendment proposal is considered a “routine” proposal, brokers, banks, and other nominees have discretionary authority to vote on the charter amendment proposal. Accordingly, we do not expect broker non-votes in connection with the charter amendment proposal.

Chord may adjourn the special meeting if a quorum is not present at the special meeting. Regardless of whether a quorum is present at the special meeting, Chord’s chair of the board or the person presiding as chairman of the special meeting may adjourn the special meeting to a later date, without notice other than announcement at the special meeting. If an adjournment is for more than 30 days, or if after the adjournment a new record date is fixed for the adjourned special meeting, Chord will provide notice of the adjourned special meeting to each Chord stockholder of record entitled to vote at that special meeting scheduled to a later date.

Beneficial Ownership of Securities

To Chord’s knowledge, the following table sets forth certain information regarding the beneficial ownership of Chord common stock as of April 8, 2024 by (i) each person who is known by Chord to own beneficially more than five percent of the outstanding shares of Chord common stock, (ii) each named executive officer of Chord, (iii) each director of Chord and (iv) all directors and executive officers as a group. It is expected that each Chord’s directors and executive officers will vote “FOR” each of the proposals.

Chord has determined beneficial ownership in accordance with the rules of the SEC. Information set forth in the tables below with respect to beneficial ownership of Chord common stock has been obtained from filings made by the named beneficial ownership with the SEC as of April 8, 2024 or, in the case of Chord’s current

56

executive officers and directors, has been provided to us by such individuals.

Required Vote

Assuming a quorum is present at the special meeting, approval of the stock issuance proposal and the adjournment proposal will each require the affirmative vote of a majority of the voting power of shares of Chord common stock present in person (online) or represented by proxy and entitled to vote thereon at the special meeting. Approval of the charter amendment proposal is not a condition to consummating the arrangement, however, adoption of the Charter Amendment is conditioned upon the Closing. Approval of the charter amendment proposal requires the affirmative vote of the holders of a majority of the voting power of shares of Chord common stock entitled to vote. An abstention from voting at the special meeting will have the same effect as a vote “AGAINST” the stock issuance proposal, the charter amendment proposal and the adjournment proposal, respectively. The failure of a Chord stockholder to submit a proxy or vote at the special meeting will have no effect on the outcome of the stock issuance proposal and the adjournment proposal and will have the same effect as a vote “AGAINST” the charter amendment proposal. A broker non-vote will not be voted on the stock issuance proposal or the adjournment proposal.

Voting by Proxy

This proxy statement is being sent to you on behalf of the Chord board of directors for the purpose of requesting that you allow your shares of Chord common stock to be represented at the special meeting by the persons named in the enclosed proxy card. All shares of Chord common stock represented at the special meeting by properly executed proxy cards, voted over the telephone or voted over the internet will be voted in accordance with the instructions indicated on those proxies. If you sign and return a proxy card without giving voting instructions, your shares will be voted as follows:

• “FOR” Proposal No. 1 – The Stock Issuance Proposal – to approve the issuance of shares of Chord common stock to Enerplus shareholders in connection with the arrangement;

• “FOR” Proposal No. 2 – The Charter Amendment Proposal – to approve the Charter Amendment to increase the number of authorized shares of Chord common stock from 120,000,000 shares to 240,000,000 shares; and

• “FOR” Proposal No. 3 – The Adjournment Proposal – to approve the adjournment or postponement of the special meeting, if necessary or appropriate, including to solicit additional proxies if there are not sufficient votes to approve the stock issuance proposal, subject to the provisions of the arrangement agreement.

How to Vote

You may vote by any of the four methods listed below. If your Chord common stock is held in “street name” by your bank, broker or other nominee, please see “How do I vote if my Chord common stock is held in “street name” by my bank, broker or other nominee?” below.

 Internet. You may vote on the Internet at http://www.proxyvote.com. This website also allows electronic proxy voting using smartphones, tablets and other web-connected mobile devices (additional charges may apply pursuant to your service provider plan). Simply follow the instructions that accompanied your proxy materials. If you vote on the Internet, you can request electronic delivery of future proxy materials. Internet voting facilities for Chord stockholders of record will be available 24 hours a day and will close at 11:59 p.m. (Eastern Time) May 13, 2024.

 Telephone. You may vote by telephone by following the instructions on the instructions that accompanied your proxy materials. Easy-to-follow voice prompts allow you to vote your stock and confirm that your vote has been properly recorded. Telephone voting facilities for Chord stockholders of record will be available 24 hours a day and will close at 11:59 p.m. (Eastern Time) on May 13, 2024.

58

 Mail. If you received a proxy card by mail, you may vote by mail by completing, signing, dating and returning your proxy card in the pre-addressed, postage-paid envelope provided. If you vote by mail and your proxy card is returned unsigned, then your vote cannot be counted. If you vote by mail and the returned proxy card is signed without indicating how you want to vote, then your proxy will be voted as recommended by the Board. If mailed, your completed and signed proxy card must be received by May 13, 2024.

 Meeting. You may attend and vote electronically at the special meeting.

The Chord board of directors recommends that you vote using one of the first three methods discussed above, as it is not practical for most Chord stockholders to attend and vote at the special meeting. Using one of the first three methods discussed above to vote will not limit your right to vote at the special meeting if you later decide to attend in person (online).

If your shares are held in “street name” by your bank, broker or other nominee, you are considered the beneficial owner of shares held in street name, and the proxy materials will be forwarded to you by your bank, broker or nominee. The bank, broker or nominee is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your bank, broker or nominee how to vote. Beneficial owners that receive the proxy materials by mail from the stockholder of record should follow the instructions included in those materials (usually a voting instruction card) to transmit voting instructions.

Revoking Your Proxy

You may revoke your proxy before the voting polls are closed at the special meeting, by the following methods:

• voting at a later time by Internet or telephone until 11:59 p.m. (Eastern Time) on May 13, 2024;

• voting in person (online) at the special meeting;

• delivering to our Corporate Secretary a proxy with a later date or a written revocation of your most recent proxy; or

• giving notice to the inspector of elections at the special meeting.

If your Chord common stock is held in street name by a bank, broker or other nominee, and you vote by proxy, you may later revoke your proxy by informing the holder of record in accordance with that entity’s procedures.

Adjournments and Postponements

Although it is not currently expected, the special meeting may be adjourned or postponed to a later date. Regardless of whether a quorum is present at the special meeting, Chord’s chair of the board or the person presiding as chairman of the special meeting may adjourn the special meeting to a later date, without notice other than announcement at the special meeting. If an adjournment is for more than 30 days, or if after the adjournment a new record date is fixed for the adjourned special meeting, Chord will provide notice of the adjourned special meeting to each Chord stockholder of record entitled to vote at that special meeting scheduled to a later date. Any adjournment of the special meeting for the purpose of soliciting additional proxies will allow Chord stockholders who have already sent in their proxies to revoke them at any time before voting occurs at the rescheduled special meeting.

Householding

One copy of this proxy statement and notice will be sent to Chord stockholders that share an address, unless they have notified Chord that they want to continue receiving multiple packages. Each Chord stockholder in the

59

household will continue to receive a separate proxy card. This process, known as “householding,” reduces the volume of duplicate information received at a household and helps to reduce Chord’s expenses. A copy will also be sent upon written or oral request to any Chord stockholder of a shared address to which a single copy was delivered. If two or more Chord stockholders with a shared address are currently receiving only one copy, then they may request to receive multiple packages in the future, or if a Chord stockholder is currently receiving multiple packages, then the Chord stockholder may request to receive a single copy in the future. Such requests may be made by writing to Investor Relations, Chord Energy Corporation, 1001 Fannin Street, Suite 1500, Houston, Texas 77002 or by calling (281) 404-9500.

Solicitation of Proxies

Chord will bear all costs of solicitation related to the special meeting. In addition to sending and making available these materials, some of Chord’s directors, officers and other employees may solicit proxies by contacting Chord stockholders via the Internet, by mail, personal interview or telephone. None of Chord’s officers or employees will receive any extra compensation for soliciting Chord stockholders. Chord may also request banking institutions, brokerage firms, custodians, nominees and fiduciaries to forward solicitation material to the beneficial owners of the common stock that those companies or persons hold of record, and Chord will reimburse the forwarding expenses. In addition, Chord has retained Alliance Advisors, LLC, to assist in the solicitation of proxies. For these proxy solicitation services, we will pay Alliance Advisors, LLC and estimated fee of approximately $28,000, plus reasonable out-of-pocket expenses and fees for any additional services.

Other Business

Chord does not expect that any matter other than the proposals listed above will be brought before the special meeting. If, however, other matters are properly brought before the special meeting, or any adjournment or postponement of the special meeting, the persons named as proxies will vote in accordance with their judgment.

THE ARRANGEMENT

This section of the proxy statement describes the material aspects of the proposed arrangement. This section may not contain all of the information that is important to you. You should carefully read this entire proxy statement and the documents incorporated by reference into this proxy statement, including the full text of the arrangement agreement, a copy of which is attached to this proxy statement as Annex A, for a more complete understanding of the proposed arrangement. In addition, important business and financial information about each of Enerplus and Chord is included in, or incorporated by reference into, this proxy statement. See the “Where You Can Find More Information” section of this proxy statement.

Structure of the Arrangement

On February 21, 2024, Chord and Canadian Sub entered into the arrangement agreement with Enerplus, pursuant to which, among other things, Canadian Sub will acquire all of the issued and outstanding Enerplus

60

common shares in exchange for stock consideration and cash consideration, with Enerplus becoming a wholly-owned subsidiary of Chord. The arrangement will be implemented by way of a Canadian plan of arrangement pursuant to the ABCA and is subject to the approval by the Court, Chord stockholders and Enerplus shareholders and certain other customary conditions precedent. The parties intend to rely upon the exemption from the registration requirements of the Securities Act pursuant to Section 3(a)(10) thereof with respect to the issuance of the Chord common stock under the arrangement.

If the arrangement is completed, Enerplus shareholders (other than Enerplus common shares held by dissenting Enerplus shareholders) will receive (i) 0.10125 of a share of Chord common stock and (ii) $1.84 in cash, in exchange for each Enerplus common share they hold, subject to adjustment as set forth in the arrangement agreement, if applicable. Any shares in respect of which dissent rights have been properly exercised and not withdrawn, pursuant to Section 191 of the ABCA, will be deemed to be transferred and assigned to Canadian Sub, but will not be entitled to receive the stock consideration or cash consideration and will, instead, be subject to dissent rights under the ABCA, as modified by the plan of arrangement and the interim order of the Court. The payment made to an Enerplus shareholder validly exercising and not withdrawing dissent rights will be reduced by the portion of the additional dividend that the Enerplus shareholder has received (or is entitled to receive), if any. Chord stockholders will continue to own their existing shares, and the Chord common stock will not be affected by the arrangement. Upon completion of the arrangement, it is expected that Chord stockholders will own approximately 67%, and Enerplus shareholders will own approximately 33% of the combined company on a fully diluted basis.

Background of the Arrangement

In the ordinary course, the Chord board of directors, consistent with its fiduciary duties, and management continually evaluate Chord’s operations, performance, strategy, financial position and future business prospects and risks in light of current business and economic conditions with a focus on generating long-term value by leveraging assets to create efficiencies, increasing free cash flow and returning cash to stockholders. In connection with such evaluation, the Chord board of directors and the Chord management team also review and assess potential strategic alternatives available to Chord, including mergers and acquisition transactions. As part of such assessments, Chord has from time to time engaged Citi, Wells Fargo Securities, LLC, J.P. Morgan Securities LLC and/or other financial advisors to assist the Chord board of directors and management in connection with such assessments, Vinson & Elkins L.L.P. (“Vinson & Elkins”) and/or Wachtell Lipton Rosen & Katz (“Wachtell Lipton”) to serve as legal counsel in connection with potential transactions and other corporate matters and, with respect to matters of Canadian law, Goodmans LLP (“Goodmans”).

Chord and Enerplus are generally familiar with one another as each has long-standing positions in the E&P industry. Representatives of each of Chord and Enerplus have discussed a strategic transaction from time to time over the past two years. The terms of the arrangement are the result of arm’s-length negotiations between Chord and Enerplus. The following is a summary of the events leading up to the signing of the arrangement agreement and key meetings, negotiations, discussions and actions involving Chord, Enerplus and their respective representatives that preceded the public announcement of the arrangement.

On May 3, 2023, Mr. Daniel Brown, Chord President, Chief Executive Officer and board member, and Mr. Ian Dundas, Enerplus President, Chief Executive Officer and board member, held a telephone call during which they discussed the challenges facing the upstream oil and gas industry as well as the relative strategic merits of a combination of Chord and Enerplus.

On May 22, 2023, the Chord board of directors convened a meeting with certain members of the Chord management team and representatives of Citi in attendance to discuss, among other things, a potential strategic transaction with Enerplus, including potential benefits and drawbacks of pursuing such a transaction relative to other strategic alternatives (including maintaining the status quo). After discussion, the Chord board of directors authorized Mr. Brown to make a non-binding proposal to acquire Enerplus at a fixed exchange ratio of 0.1090 of a share of Chord common stock for each outstanding Enerplus common share, comprised of 80% stock and 20%

61

cash consideration equating to 0.0872 of a share of Chord common stock and cash consideration equal in value to 0.0218 of a share of Chord common stock per Enerplus common share, subject to the completion of due diligence and negotiation of definitive documentation (the “First Chord Proposal”). The First Chord Proposal implied a total value of $16.37 per Enerplus common share based on closing share prices on May 23, 2023 and would have resulted in Chord stockholders and Enerplus shareholders owning approximately 70% and 30% of the combined company, respectively. The First Chord Proposal implied a 10.4% premium to the closing price of Enerplus common shares on the NYSE on May 23, 2023.

On May 30, 2023, Mr. Brown and Mr. Dundas had a telephone call to discuss the First Chord Proposal. Mr. Dundas expressed to Mr. Brown that Enerplus was not interested in pursuing a combination at that time.

On June 6, 2023, Mr. Lynn Peterson, the Chair of the Chord board of directors at the time, called Ms. Hilary Foulkes, the Chair of the Enerplus board of directors, to follow up on the First Chord Proposal and Enerplus’ reaction thereto. Mr. Peterson advised Ms. Foulkes that Chord remained interested in pursuing a business combination between the parties and would remain available for future discussions.

Between early June 2023 and late November 2023, the Chord board of directors, with the assistance of Chord management and Chord’s external advisors, continued to evaluate strategic alternatives and business development opportunities, including a potential business combination with Enerplus.

On August 2, 2023, Chord issued its earnings release for the second quarter of 2023 announcing, among other things, that Chord had consummated $31.0 million in share repurchases during the second quarter of 2023 at a weighted average price of $147.59 per share of Chord common stock and that the Chord board of directors had declared a base-plus-variable cash dividend of $1.36 per share of Chord common stock with respect to the second quarter of 2023.

On November 1, 2023, the closing price of Chord common stock on the Nasdaq was $165.35 per share and the closing price of Enerplus common shares on the NYSE was $16.93 per share.

On November 2, 2023 Enerplus issued its earnings release for the third quarter of 2023 which announced, among other things, that Enerplus had consummated approximately $55.1 million in share repurchases during the third quarter of 2023 at a weighted average price of $16.85 per Enerplus common share. Additionally, the Enerplus board of directors had declared a cash dividend of $0.06 per Enerplus common share.

On November 17, 2023, the Chord board of directors convened a meeting attended by members of Chord management and representatives of Citi to discuss potential strategic alternatives and business development opportunities, including a potential transaction with Enerplus. After discussion and consideration of various

62

alternatives the Chord board of directors had evaluated over the past several months, the Chord board of directors authorized and instructed Mr. Brown to initiate discussions with Mr. Dundas regarding a potential business combination between Chord and Enerplus and provide to Enerplus a non-binding proposal for an all-stock combination in which Enerplus shareholders would receive a fixed exchange ratio of 0.1155 of a share of Chord common stock for each outstanding Enerplus common share, subject to the completion of due diligence and negotiation of definitive documentation (the “Second Chord Proposal”).

On November 20, 2023, Mr. Brown had a telephone call with Mr. Dundas. Mr. Brown expressed that Chord remained interested in pursuing a potential business combination with Enerplus and shared Chord’s view of the potential benefits of such a combination. Following this call and on the same date, Chord sent Enerplus the Second Chord Proposal. The proposed all-stock exchange ratio in the Second Chord Proposal represented an implied a value of $18.78 per Enerplus common share based on closing share prices on November 17, 2023. The combination would have resulted in Chord stockholders and Enerplus shareholders owning approximately 64% and 36% of the pro forma company, respectively. The Second Chord Proposal implied a 15.5% premium to the closing price of Enerplus common shares on the NYSE on November 17, 2023. On November 17, 2023, the closing price of Chord common stock on the Nasdaq was $162.59 per share and the closing price of Enerplus common shares on the NYSE was $16.26 per share.

On November 30, 2023, Mr. Brown had a telephone call with Mr. Dundas, in which Mr. Dundas informed Mr. Brown that the Enerplus board of directors would be holding a meeting the following week to discuss, among other things, the Second Chord Proposal. Mr. Dundas informed Mr. Brown that Enerplus would reach out following the meeting.

On December 5, 2023, Mr. Dundas contacted Mr. Brown to advise him that Enerplus was continuing to evaluate the Second Chord Proposal and was interested in pursuing discussions in respect of a potential business combination with Chord, including proceeding to an exchange of information to facilitate reciprocal due diligence and evaluation of the merits of a business combination transaction between the parties. Mr. Brown and Mr. Dundas discussed certain preliminary matters regarding the terms of the Second Chord Proposal, including, among other things, the proposed consideration (including the amount and type), preliminary due diligence matters, process and expected timeline to reach a definitive agreement. Mr. Brown and Mr. Dundas agreed that, as an immediate next step, the parties should sign a non-disclosure agreement to further progress discussions and facilitate the exchange of non-public information, and Mr. Brown stated that Chord would provide a draft non-disclosure agreement to Enerplus for review.

On December 6, 2023, representatives of Chord sent representatives of Enerplus an initial draft of a mutual non-disclosure agreement.

On December 7, 2023, the Chord board of directors convened a meeting with certain members of the Chord management team to discuss, among other things, the status of the review and evaluation of a potential business combination with Enerplus. At the meeting, Mr. Brown updated the Chord board of directors on his subsequent conversations with Mr. Dundas regarding the Second Chord Proposal. After discussion, the Chord board of directors authorized management (together with Chord’s advisors) to continue its evaluation and negotiation of a business combination with Enerplus.

During the week of December 11, 2023, Mr. Brown had multiple telephone discussions with Mr. Dundas concerning the terms of the non-disclosure agreement and a proposed timeline for pursuing a potential transaction, including the proposed due diligence process. On December 12, 2023, Chord and Enerplus entered into a mutual non-disclosure agreement, which contained, among other things, mutual standstill obligations in favor of each party. On December 13, 2023, Mr. Brown and Mr. Dundas discussed via email next steps, timing and logistics, as well as the exchange of relevant due diligence materials via virtual data rooms.

63

On December 18, 2023, Mr. Brown and Mr. Dundas held a virtual meeting during which they discussed process, logistics and timing, including Chord’s anticipated timing for circulating an initial draft of an arrangement agreement and plan of arrangement.

On December 22, 2023, Chord delivered initial drafts of an arrangement agreement and plan of arrangement to representatives of Enerplus contemplating a transaction in which a wholly owned subsidiary of Chord would acquire Enerplus in an all-stock transaction. The draft arrangement agreement included, among other things, (i) limited representations and warranties and covenants of Chord relative to those applicable to Enerplus, (ii) mutual non-solicitation covenants with customary exceptions, (iii) provisions prohibiting each party from terminating the arrangement agreement in order to accept a “superior proposal” unless such party’s stockholders or shareholders, as applicable, had voted on and failed to approve the transaction (a “force the vote provision”), (iv) amounts payable by either party if its stockholders or shareholders, as applicable, voted on and failed to approve the transaction (“naked no-vote termination fees”) and (v) a six-month “outside date,” subject to a six-month extension exercisable by either party in certain circumstances.

On December 27, 2023, the Chord board of directors appointed Susan Cunningham to serve as the Chair of the Chord board of directors, effective January 1, 2024, in connection with the conclusion of Lynn A. Peterson’s service as Executive Chair of the Chord board of directors on December 31, 2023. Mr. Brown sent a message to Mr. Dundas informing him of the appointment.

After discussion, the Chord board of directors authorized Mr. Brown to deliver to Enerplus a revised non-binding proposal pursuant to which Enerplus shareholders would receive a fixed exchange ratio of 0.1090 of a share of Chord common stock for each outstanding Enerplus common share, comprised of 80% stock and 20% cash consideration equating to 0.0872 of a share of Chord common stock and cash consideration of $3.37, which was equal in value to 0.0218 of a share of Chord common stock per Enerplus common share (the “Third Chord Proposal”).

Mr. Dundas indicated to Mr. Brown that Enerplus was also discussing a potential strategic transaction with other counterparties and requested that Chord submit a revised proposal by February 10, 2024 to enable the Enerplus board of directors to make a final decision regarding the different proposals it was evaluating.

On the morning of February 8, 2024, a third-party media source publicly reported that Enerplus had been approached with an acquisition proposal from Devon Energy Corporation, following which there was an increase in the trading price of Enerplus’ shares. Also on February 8, 2024, Mr. Brown and Mr. Dundas held a telephone call during which they discussed the post-transaction governance structure, timing and employee matters.

On February 9, 2024, the Chord board of directors convened a meeting with certain members of the Chord management team and representatives of Citi in attendance to discuss, among other things, the status of the review and evaluation of a potential business combination with Enerplus. At the meeting, Mr. Brown and other members of Chord management provided an update on the status of due diligence and negotiations with Enerplus, including his February 8, 2024 discussion with Mr. Dundas. After discussion, the Chord board of directors authorized Mr. Brown to make a revised non-binding proposal to acquire Enerplus in a cash-and-stock acquisition in which Enerplus shareholders would receive a fixed exchange ratio of 0.1110 of a share of Chord common stock for each outstanding Enerplus common share, comprised of 90% stock and 10% cash consideration equating to 0.0999 of a share of Chord common stock and cash consideration of $1.73, which was in value to 0.0111 of a share of Chord common stock per Enerplus common share (the “Fourth Chord Proposal”).

On February 10, 2024, representatives of Chord sent representatives of Enerplus the Fourth Chord Proposal, along with a revised draft investor presentation. The proposed consideration in the Fourth Chord Proposal implied a value of $17.32 per Enerplus common share based on closing share prices on February 9, 2024 and would have resulted in Chord stockholders and Enerplus shareholders owning approximately 67% and 33% of the pro forma company, respectively. In addition, Chord provided Enerplus with an overview of key considerations reflected in the Fourth Chord Proposal in the form of an issues list, which was prepared by Chord’s outside legal advisors and discussed with the Chord management team. Mr. Brown and Mr. Dundas had a telephone call to discuss the Fourth Chord Proposal, including valuation, composition of cash and equity consideration, and overall timing. The Fourth Chord Proposal implied an 11.4% premium to the closing price of Enerplus common shares on the NYSE on February 9, 2024. On February 9, 2024, the closing price of Chord common stock on the Nasdaq was $156.02 per share and the closing price of Enerplus common shares on the NYSE was $15.55 per share.

On February 14, 2024, Mr. Brown and Mr. Dundas had a telephone call to discuss the Fourth Chord Proposal, during which Mr. Dundas requested an increase in the proposed exchange ratio to 0.1125 of a share of Chord common stock for each outstanding Enerplus common share (inclusive of the implied exchange ratio by the cash portion of the proposal). Mr. Brown and Mr. Dundas also continued their discussions of continuing Enerplus employees, post-closing compensation, allocation of workstreams, expected synergies and return of capital strategy to be included in any deal announcement, the proportionality of the Chord dividend for Enerplus shareholders, and certain post-closing governance matters, including the number of board members of the combined company to be designated by Enerplus.

Additionally, on February 14, 2024, the Chord board of directors held its regularly scheduled meeting, at which certain members of the Chord management team were present, during which they discussed certain open points regarding post-closing governance, including the post-closing board composition and Mr. Dundas’s position with the combined company. Following discussion of Enerplus’ position regarding the Fourth Chord Proposal, the Chord board of directors determined to revise Chord’s non-binding proposal to acquire Enerplus to provide terms pursuant to which Enerplus shareholders would receive a fixed exchange ratio of 0.1125 of a share of Chord common stock for each outstanding Enerplus common share, comprised of 90% stock and 10% cash consideration equating to 0.10125 of a share of Chord common stock and cash consideration of $1.84, which was equal in value to 0.01125 of a share of Chord common stock per Enerplus common share (the “Fifth Chord Proposal”). The Fifth Chord Proposal also provided that, in connection with the Closing, Enerplus would be entitled to declare an additional dividend in an amount intended to equalize dividends declared to Enerplus shareholders with dividends declared to Chord stockholders during the period between execution of the arrangement agreement and the closing date, other than the dividends paid in March 2024 to the companies’ respective shareholders with respect to the fourth quarter of 2023.

Also on February 14, 2024, Mr. Brown and Mr. Dundas had a subsequent telephone call during which Mr. Brown informed Mr. Dundas that, subject to final approvals, the Chord board of directors had agreed to the matters raised during their previous telephone call, including Enerplus’ right to designate three independent board members and one non-independent board member to the pro forma board of directors which, relative to Chord’s right to designate six independent board members and one non-independent board member, would result in Enerplus and Chord each having the right to designate a number of independent board members approximately proportionate to their respective shareholders’ pro forma ownership of the combined company.

On February 15, 2024, Ms. Cunningham and Ms. Foulkes, held two telephone calls during which they discussed a potential transaction between Chord and Enerplus and certain post-closing governance matters, including the composition of the board of directors of the combined company. Thereafter, the Chord board of directors reconvened and discussed the conversation between Ms. Cunningham and Ms. Foulkes.

On February 16, 2024, representatives of Chord shared a revised draft of the arrangement agreement with representatives of Enerplus and conveyed the terms of the Fifth Chord Proposal. The Fifth Chord Proposal implied a value of $18.42 per Enerplus common share based on closing share prices on February 16, 2024. Among other things, the revised draft also proposed that the combined company would have seven directors designated by Chord and four designated by Enerplus. The Fifth Chord Proposal implied a 12.9% premium, and an 11.1% dividend-adjusted premium, to the closing price of Enerplus common shares on the NYSE on February 16, 2024 and would have resulted in Chord stockholders and Enerplus shareholders owning approximately 67% and 33% of the pro forma company, respectively. On February 16, 2024, the closing price of Chord common stock on the Nasdaq was $163.71 per share and the closing price of Enerplus common shares on the NYSE was $16.32 per share.

On February 17, 2024, Blake, Cassels & Graydon LLP (“Blakes”) and Latham & Watkins LLP (“Latham”), Enerplus’ legal counsel, shared revised drafts of the arrangement agreement and plan of arrangement with Vinson & Elkins, Wachtell Lipton and Goodmans.

On February 19, 2024, Mr. Brown and Mr. Dundas held discussions regarding certain arrangement agreement terms relating to post-closing governance, including the composition of the combined company board, and employee compensation matters. Vinson & Elkins shared a revised draft of the arrangement agreement reflecting these conversations with Blakes and Latham.

Early in the morning on February 20, 2024, Blakes and Latham shared a revised draft of the arrangement agreement with Vinson & Elkins, Wachtell Lipton and Goodmans. Later on February 20, 2024, the Chord board of directors convened a meeting in which certain members of the Chord management team and representatives of Citi, Vinson & Elkins, Wachtell Lipton and Goodmans were present. At the meeting, Citi reviewed its preliminary financial analysis of the proposed consideration payable by Chord in the arrangement with the Chord board of directors and Vinson & Elkins, Wachtell Lipton and Goodmans presented on the terms of the arrangement agreement and the plan of arrangement and answered questions from the Chord board of directors with respect thereto. Prior to this meeting, Citi provided to the Chord board of directors certain information regarding Citi’s material investment banking relationships with Chord and Enerplus during the approximate prior two-year period. A further discussion then ensued regarding, among other things, the terms of the arrangement agreement and the plan of arrangement, including the exchange ratio, cash consideration, implied post-closing ownership and governance of the combined company, the internal and external transaction rollout plan, and pro forma and other financial matters.

Also on February 20, 2024, Mr. Brown and Mr. Dundas had a telephone call during which they discussed the treatment of director, officer and other employee compensation, and post-closing governance matters. Later that night and into February 21, 2024, Vinson & Elkins, Wachtell Lipton, Goodmans, Blakes and Latham worked to finalize the arrangement agreement and the plan of arrangement and all ancillary documentation, and including defining the cash component of the consideration to be paid in the arrangement as $1.84 per Enerplus common share.

At the meeting, Citi reviewed its financial analysis of the consideration provided for in the arrangement with the Chord board of directors and rendered an oral opinion, confirmed by delivery of a written opinion dated February 21, 2024, to the Chord board of directors to the effect, that, as of such date and based on and subject to various assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken by Citi, the consideration to be paid by Chord pursuant to the arrangement agreement was fair, from a financial point of view, to Chord. Representatives of Vinson & Elkins, Wachtell Lipton and Goodmans discussed with the Chord board of directors the final terms of the arrangement agreement, following which the Chord board of directors unanimously (i) determined that the arrangement agreement, the plan of arrangement and the transactions contemplated thereby are fair to, and in the best interests of, Chord and its stockholders, (ii) approved and declared advisable the arrangement agreement, the plan of arrangement and the transactions contemplated thereby, including the issuance of shares of Chord common stock in connection with the arrangement, and (iii) resolved to recommend that Chord stockholders approve such stock issuance.

Chord’s Reasons for the Arrangement

In evaluating the arrangement agreement and the transactions contemplated thereby, the Chord board of directors consulted with Chord’s management and legal and financial advisors. The Chord board of directors considered a number of factors when evaluating the arrangement, many of which, support the Chord board of director’s determination that the transactions contemplated by the arrangement agreement are advisable and in the best interests of Chord and its stockholders. The Chord board of directors considered these factors as a whole and without assigning relative weight to each such factor, and overall considered the relevant factors to be favorable to, and supportive of, its determinations and recommendations. These factors (which are not necessarily presented in order of relative importance and are not exhaustive) included:

• the belief that the arrangement will materially increase Chord’s scale with a leasehold position of approximately 1.3 million net acres, 98% of which is in the Williston Basin, and fourth quarter 2023 net production of 287 MBoe/day, over 90% of which is from the Williston Basin, which increased scale is expected to drive efficiencies and improved investor relevance;

• the belief that the addition of Enerplus’ inventory will meaningfully increase Chord’s total inventory that is capable of achieving breakeven at oil prices below $60/Bbl WTI by 60%, and that the combined company’s inventory could support approximately ten years of development at the current pace;

68

• the belief that the arrangement is accretive to key financial metrics, including cash flow per share, free cash flow per share, net asset value and return of capital;

• the belief that the arrangement will provide up to $150.0 million per year in administrative, capital and operating synergies, including administrative synergies of up to $40.0 million by the end of 2025, capital synergies of up to $55.0 million by the end of 2026 and operating synergies of up to $55.0 million by the end of 2026, resulting in enhanced free cash flow and uplift in equity value;

• the belief that the combined company will generate free cash flow of $1.2 billion in 2024 (assuming $79/Bbl WTI and $2.50/Mcf Henry Hub);

• the belief that the arrangement will provide strong free cash flow and attractive reinvestment rates that further enhance Chord’s current return of capital program, as the combined company is expected to distribute 75% of free cash flow in the second half of 2024;

• the belief that the material increase in Chord’s market capitalization increases the potential upside in the total value of Chord’s equity, moves Chord into a new peer group, and provides greater trading liquidity to Chord stockholders;

• the belief that the combined company will have an improved credit profile and lower cost of capital, positioning Chord for additional index inclusion, stronger credit ratings, and lower cost future financings, as compared to Chord on a standalone basis;

• the belief that the combined company will have increased financial strength and flexibility, with an expected pro forma leverage ratio of approximately 0.2x net debt to annualized EBITDA at Closing (assuming $79/Bbl WTI and $2.50/Mcf Henry Hub);

• the ability of Chord to continue to pay dividends pursuant to its previously announced return of capital plan during the pendency of the arrangement;

• the belief that Chord will continue to be led by a strong, experienced management team, with the current Enerplus President and Chief Executive Officer joining the Chord board of directors as well as serving as an advisor to the Chief Executive Officer of Chord, which will add further valuable expertise and in-depth familiarity with Enerplus to the Chord board of directors and management team, enhancing the likelihood of realizing the integration and strategic benefits that Chord expects to derive from the arrangement;

• the belief that the combined company will continue to progress key environmental, safety and governance initiatives, building on prior success realized by both Chord and Enerplus;

• the terms of the arrangement agreement, including the structure of the transaction, the conditions to each party’s obligation to complete the arrangement, the ability of the Chord board of directors to engage with third parties regarding alternative proposals in certain circumstances, the ability of the Chord board of directors to change its recommendation with respect to the transactions contemplated by the arrangement agreement under certain circumstances and that the arrangement agreement provides that, in certain circumstances, Enerplus could be required to pay a termination fee of $127.0 million to Chord;

• the belief that the restrictions imposed on Chord’s business and operations during the pendency of the arrangement are reasonable and not unduly burdensome;

• that the exchange ratio to Enerplus shareholders is fixed and will not fluctuate in the event that the market price of Enerplus common shares increases relative to the market price of Chord common stock between the date of the arrangement agreement and the Closing;

• the likelihood of consummation of the arrangement and the Chord board of directors’ evaluation of the likely timeframe necessary to close the arrangement;

• that Chord stockholders will have the opportunity to vote on the stock issuance proposal, which is a condition precedent to the arrangement;

69

• the Chord board of directors’ knowledge of, and discussions with, Chord senior management and its advisors regarding Chord’s and Enerplus’ business operations, financial condition, results of operations and prospects, taking into account Chord’s due diligence investigation of Enerplus;

• the Chord senior management team’s recommendation in support of the arrangement; and

• the opinion, dated February 21, 2024, of Citi to the Chord board of directors as to the fairness, from a financial point of view and as of the date of the opinion, to Chord of the consideration to be paid by Chord pursuant to the arrangement agreement, which opinion was based on and subject to various assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken by Citi, as more fully described in the section titled “The Arrangement — Opinion of Financial Advisor to Chord.”

The Chord board of directors also considered a variety of risks and other potentially negative factors associated with the arrangement agreement and the transactions contemplated thereby. These factors (which are not necessarily presented in order of relative importance and are not exhaustive) included:

• the possibility that the arrangement may not be completed or that completion may be unduly delayed for reasons beyond the control of Chord or Enerplus, including the failure to receive necessary Regulatory Approvals or Chord stockholder approval of the stock issuance proposal or Enerplus shareholder approval of the arrangement resolution;

• that the exchange ratio in the arrangement agreement is fixed and, as a result, Chord stockholders cannot be certain at the time of the special meeting of the total market value of the consideration to be paid, and the possibility that Chord stockholders could be adversely affected in the event that the market price of Chord common stock increases relative to the market price of Enerplus common shares between the date of the arrangement agreement and the Closing;

• that there are significant risks inherent in integrating the operations of Enerplus into Chord, including that expected synergies may not be realized, and that successful integration will require the dedication of significant management resources, which will temporarily detract attention from the day-to-day businesses of the combined company;

• that the arrangement agreement provides that, in certain circumstances, Chord could be required to pay a termination fee of $240.0 million to Enerplus;

• the negative effect that the length of time from announcement of the arrangement until completion of the arrangement could have on the market price of Chord common stock, Chord’s operating results and Chord’s relationship with its employees, stockholders and industry contacts and others who do business with Chord;

• that the restrictions on the conduct of Chord’s business prior to the consummation of the arrangement, although believed to be reasonable and not unduly burdensome, may delay or prevent Chord from undertaking business opportunities that may arise or other actions it would otherwise take with respect to the operations of Chord pending the consummation of the arrangement;

• that while the arrangement agreement only permits the Enerplus board of directors to change its recommendation in certain circumstances, the arrangement agreement permits Enerplus to terminate the arrangement agreement in certain circumstances in order to enter into a definitive agreement with respect to a superior proposal;

• that the arrangement agreement restricts Chord’s ability to entertain alternative transactions unless certain conditions are satisfied;

• the substantial costs to be incurred in connection with the arrangement, including cash consideration and stock consideration, integrating the businesses of Chord and Enerplus, and advisor and other transaction costs to be incurred in connection with the arrangement;

70

• the possibility of losing key employees and skilled workers as a result of the expected consolidation of Chord’s and Enerplus’ personnel when the arrangement is completed;

• the potential for litigation relating to the arrangement and the associated costs, burden and inconvenience involved in defending those proceedings;

• the potential that Chord’s management team will need to expend a significant amount of its time and attention to implementing the arrangement, including making arrangements for the integration of Enerplus’ and Chord’s operations, assets and employees following the arrangement;

• the risks associated with the occurrence of events that may materially and adversely affect the financial condition, properties, assets, liabilities, business or results of operations of Enerplus and its subsidiaries but that may not entitle Chord to terminate the arrangement agreement;

• that Enerplus shareholders are entitled to dissent rights in accordance with the plan of arrangement, and that there is no condition in the arrangement allowing for termination of the arrangement agreement if Enerplus shareholders exercise such rights in respect of a significant number of Enerplus common shares, which will result in a higher than estimated cash outlay in relation to the arrangement; and

• other risks of the type and nature described in the section titled “Risk Factors.”

After taking into account the factors set forth above, among others, the Chord board of directors concluded that the risks, uncertainties, restrictions and potentially negative factors associated with the arrangement were outweighed by the potential benefits of the arrangement to Chord stockholders.

This foregoing discussion of the information and factors considered by the Chord board of directors as a whole in reaching its conclusion and recommendations includes the principal factors considered by the Chord board of directors with respect to the arrangement but is not intended to be exhaustive and is not provided in any specific order or ranking. In view of the wide variety of factors considered by the Chord board of directors in evaluating the arrangement agreement and the transactions contemplated thereby, and the complexity of these matters, the Chord board of directors did not find it practicable to, and did not attempt to, quantify, rank or otherwise assign relative weight to those factors. In addition, different members of the Chord board of directors may have given different weight to different factors. The Chord board of directors did not reach any specific conclusion with respect to any of the factors considered and instead conducted an overall analysis of such factors and determined that, in the aggregate, the potential benefits considered outweighed the potential risks or possible negative consequences of approving the arrangement agreement and the issuance of Chord common stock pursuant to the arrangement agreement.

In considering the recommendation of the Chord board of directors to approve each of the proposals, Chord stockholders should be aware that Chord directors and executive officers may have interests in the arrangement that are different from, or in addition to, the interests of Chord stockholders generally, as further described in the section titled “The Arrangement—Interests of Chord Directors and Executive Officers in the Arrangement.”

It should be noted that this explanation of the reasoning of the Chord board of directors and certain information presented in this section is forward-looking in nature and should be read in light of the factors set forth in “Cautionary Statement Regarding Forward-Looking Statements.”

Recommendation of the Chord Board of Directors

After careful consideration, the Chord board of directors has determined that it is advisable and in the best interests of Chord and its stockholders to consummate the arrangement as contemplated by the arrangement agreement and adopt the Charter Amendment, conditioned upon the Closing. Accordingly, the Chord board of directors unanimously recommends that Chord stockholders vote:

71

• “FOR” the stock issuance proposal;

• “FOR” the charter amendment proposal; and

• “FOR” the adjournment proposal.

Opinion of Financial Advisor to Chord

Chord has engaged Citi as Chord’s financial advisor in connection with the proposed arrangement. In connection with Citi’s engagement, the Chord board of directors requested that Citi evaluate the fairness, from a financial point of view, to Chord of the consideration to be paid by Chord pursuant to the arrangement agreement. On February 21, 2024, at a meeting of the Chord board of directors held to evaluate the proposed arrangement, Citi rendered an oral opinion, confirmed by delivery of a written opinion dated February 21, 2024, to the Chord board of directors to the effect that, as of such date and based on and subject to various assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken by Citi, the consideration to be paid by Chord pursuant to the arrangement agreement was fair, from a financial point of view, to Chord.

The full text of Citi’s written opinion, dated February 21, 2024, which describes the assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken, is attached as Annex C to this proxy statement and is incorporated into this proxy statement by reference. The description of Citi’s opinion set forth below is qualified in its entirety by reference to the full text of Citi’s opinion. Citi’s opinion was provided for the information of the Chord board of directors (in its capacity as such) in connection with its evaluation of the consideration from a financial point of view to Chord and did not address any other terms, aspects or implications of the arrangement. Citi expressed no view as to, and its opinion did not address, the underlying business decision of Chord to effect or enter into the arrangement, the relative merits of the arrangement as compared to any alternative business strategies that might exist for Chord or the effect of any other transaction that Chord might engage in or consider. Citi’s opinion was not intended to be and did not constitute a recommendation as to how the Chord board of directors, and is not intended to be and does not constitute a recommendation as to how any securityholder, should vote or act on any matters relating to the proposed arrangement or otherwise.

In arriving at its opinion, Citi:

• reviewed a draft, dated February 21, 2024, of the arrangement agreement;

• held discussions with certain senior officers, directors and other representatives of Chord and certain senior officers and other representatives of Enerplus concerning the businesses, operations and prospects of Chord and Enerplus;

• reviewed certain publicly available and other business and financial information relating to Chord and Enerplus provided to or discussed with Citi by the managements of Chord and Enerplus, including certain financial forecasts and other information and data relating to Chord and Enerplus, and future commodity price estimates and assumptions, prepared by the management of Chord;

• reviewed certain information and data provided to or discussed with Citi by the management of Chord relating to the potential strategic implications and financial and operational benefits (including the amount, timing and achievability thereof) anticipated by such management to result from the arrangement;

• reviewed the financial terms of the arrangement as set forth in the arrangement agreement in relation to, among other things, current and historical market prices of Chord common stock and Enerplus common shares, the financial condition and certain historical and projected financial and operating data of Chord and Enerplus, and the capitalization of Chord and Enerplus;

• reviewed certain financial, stock market and other publicly available information relating to the businesses of certain other companies whose operations Citi considered relevant in evaluating those of Chord and Enerplus;

72

In rendering its opinion, Citi assumed and relied, without independent verification, upon the accuracy and completeness of all financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with Citi and upon the assurances of the managements and other representatives of Chord and Enerplus that they were not aware of any relevant information that was omitted or that remained undisclosed to Citi. With respect to the financial forecasts and other information and data, including future commodity price estimates and assumptions, that Citi was directed to utilize in its analyses, Citi was advised by the management of Chord and Citi assumed, with Chord’s consent, that they were reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of Chord as to, and were a reasonable basis upon which to evaluate, the future financial performance of Chord and Enerplus, the potential strategic implications and financial and operational benefits (including the amount, timing and achievability thereof) anticipated by such management to result from, and other potential pro forma financial effects of, the arrangement and the other matters covered thereby. Citi expressed no view or opinion as to any financial forecasts and other information or data (or underlying assumptions on which they were based) provided to or otherwise reviewed by or discussed with Citi and Citi assumed, with Chord’s consent, that the financial results, including with respect to the potential strategic implications and financial and operational benefits anticipated to result from the arrangement, reflected in such financial forecasts and other information and data would be realized in the amounts and at the times projected.

Citi relied, at Chord’s direction, upon the assessments of the managements of Chord and Enerplus, as the case may be, as to, among other things, (i) the oil, natural gas and natural gas liquids reserves, reservoir characteristics, undeveloped well inventory, drilling and well development, gathering and transportation and other exploration, development and production activities, as applicable, of Chord and Enerplus, including related costs and expenditures and capital funding requirements, (ii) the potential impact on Chord and Enerplus of macroeconomic, geopolitical, market, competitive, seasonal and other conditions, trends and developments in and prospects for, and governmental, regulatory and legislative matters relating to or otherwise affecting, the oil, natural gas and natural gas liquids industry, including with respect to the geographic regions and basins in which Chord and Enerplus operate, environmental regulations and commodity pricing and supply and demand for oil, natural gas and natural gas liquids, which are subject to significant volatility and which, if different than as assumed, could have a material impact on our analyses or opinion, (iii) existing and future agreements and other arrangements involving, and the ability to attract, retain and/or replace, key employees, customers, service providers, derivatives counterparties and other commercial relationships of Chord and Enerplus, and (iv) the ability of Chord to integrate the operations of Chord and Enerplus and to realize the potential strategic implications and financial and operational benefits as contemplated and as to tax matters relating to Chord and Enerplus both on a standalone and pro forma basis. Citi assumed, with Chord’s consent, that there would be no developments with respect to any such matters, any pre-closing restructurings or entity dissolutions involving Enerplus or adjustments to the consideration that would have an adverse effect on Chord, Enerplus or the arrangement (including the contemplated benefits thereof) or that otherwise would be meaningful in any respect to Citi’s analyses or opinion.

Citi did not make and, except for certain reserve reports relating to Chord and Enerplus, was not provided with an independent evaluation or appraisal of the assets or liabilities (contingent, accrued, derivative, off-balance sheet or otherwise) of Chord, Enerplus or any other entity nor did Citi make any physical inspection of the properties or assets of Chord, Enerplus or any other entity. Citi expressed no view or opinion as to reserve

Citi did not evaluate the solvency or fair value of Chord, Enerplus or any other entity under any state, federal, provincial or other laws relating to bankruptcy, insolvency or similar matters. Citi expressed no view or opinion as to any actual or potential litigation, claims or governmental, regulatory or other proceedings, enforcement actions, consent decrees or other orders, audits or investigations or the potential impact thereof on Chord, Enerplus or any other entity or the arrangement.

Citi assumed, with Chord’s consent, that the arrangement would be consummated in accordance with its terms and in compliance with all applicable laws, documents and other requirements, without waiver, modification or amendment of any material term, condition or agreement, and that, in the course of obtaining the necessary governmental, regulatory or third party approvals, consents, releases, waivers and agreements for the arrangement or otherwise, no delay, limitation, restriction, condition or other action, including any divestiture or other requirements, amendments or modifications, would be imposed or occur that would have an adverse effect on Chord, Enerplus or the arrangement (including the contemplated benefits thereof) or that otherwise would be meaningful in any respect to Citi’s analyses or opinion. Representatives of Chord advised Citi, and Citi also assumed, that the final terms of the arrangement agreement would not vary materially from those set forth in the draft reviewed by Citi. Citi’s opinion, as set forth therein, related to the relative values of Chord and Enerplus (after taking into account the cash consideration). Citi did not express any view or opinion as to the actual value of Chord common stock when issued in connection with the arrangement or the prices at which Chord common stock, Enerplus common shares or any other securities of Chord or Enerplus may trade or otherwise be transferable at any time, including following the announcement or consummation of the arrangement. Citi also did not express any view or opinion with respect to accounting, tax, regulatory, legal or similar matters, including, without limitation, as to tax or other consequences of the arrangement or otherwise or changes in, or the impact of, accounting standards or tax and other laws, regulations and governmental and legislative policies affecting Chord, Enerplus or the arrangement (including the contemplated benefits thereof), and Citi relied, with Chord’s consent, upon the assessments of representatives of Chord as to such matters.

Citi’s opinion addressed only the fairness, from a financial point of view and as of the date of such opinion, to Chord of the consideration (to the extent expressly specified herein), and did not address any terms, aspects or implications of the arrangement, including, without limitation, the form or structure of the arrangement, any regular or additional dividends contemplated by the arrangement agreement, adjustments to the consideration, pre-closing restructurings or entity dissolutions or any other terms, aspects or implications of any agreement, arrangement or understanding to be entered into in connection with or contemplated by the arrangement or otherwise. Citi expressed no view as to, and its opinion did not address, the underlying business decision of Chord to effect or enter into the arrangement, the relative merits of the arrangement as compared to any alternative business strategies that might exist for Chord or the effect of any other transaction that Chord might engage in or consider. Citi also expressed no view as to, and its opinion did not address, the fairness (financial or otherwise) of the amount or nature or any other aspect of any compensation or other consideration to any officers, directors or employees of any parties to the arrangement, or any class of such persons, relative to the consideration or otherwise. Citi’s opinion was necessarily based upon information available, and financial, stock market and other conditions and circumstances existing and disclosed, to Citi as of the date of its opinion. Although subsequent developments may affect its opinion, Citi has no obligation to update, revise or reaffirm its opinion. As the Chord board of directors was aware, the industries in which Chord and Enerplus operate (including commodity prices related to such industries) and the securities of Chord and Enerplus have experienced and may continue to experience volatility and disruptions, and Citi expressed no view or opinion as to any potential effects of such volatility or disruptions on Chord, Enerplus or the arrangement (including the contemplated benefits thereof). The issuance of Citi’s opinion was authorized by Citi’s fairness opinion committee.

In preparing its opinion, Citi performed a variety of financial and comparative analyses, including those described below. The summary of the analyses below is not a complete description of Citi’s opinion or the

74

analyses underlying, and factors considered in connection with, Citi’s opinion. The preparation of a financial opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a financial opinion is not readily susceptible to summary description. Citi arrived at its ultimate opinion based on the results of all analyses and factors assessed as a whole, and it did not draw, in isolation, conclusions from or with regard to any one factor or method of analysis. Accordingly, Citi believes that the analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying such analyses and its opinion.

In its analyses, Citi considered industry performance, general business, economic, market and financial conditions and other matters existing as of the date of its opinion, many of which are beyond the control of Chord and Enerplus. No company, business or transaction reviewed is identical or directly comparable to Chord, Enerplus or the arrangement and an evaluation of these analyses is not entirely mathematical; rather, the analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the public trading, acquisition or other values of the companies, businesses or transactions reviewed or the results of any particular analysis.

The estimates contained in Citi’s analyses and the ranges resulting from any particular analysis are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by such analyses. In addition, analyses relating to the value of businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold or acquired. Accordingly, the estimates used in, and the results derived from, Citi’s analyses are inherently subject to substantial uncertainty.

Citi was not requested to, and it did not, recommend or determine the specific consideration payable in the arrangement. The type and amount of consideration payable in the arrangement were determined through negotiations between Chord and Enerplus and the decision to enter into the arrangement agreement was solely that of the Chord board of directors. Citi’s opinion was only one of many factors considered by the Chord board of directors in its evaluation of the arrangement and should not be viewed as determinative of the views of the Chord board of directors or Chord management with respect to the arrangement or the consideration.

Financial Analyses

The summary of the financial analyses described below under this heading “—Financial Analyses” is a summary of the material financial analyses reviewed with the Chord board of directors and performed by Citi in connection with Citi’s opinion, dated February 21, 2024. The summary set forth below does not purport to be a complete description of the financial analyses performed by, and underlying the opinion of, Citi, nor does the order of the financial analyses described represent the relative importance or weight given to those financial analyses by Citi. Certain financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses, the tables must be read together with the text of each summary as the tables alone do not constitute a complete description of the financial analyses. Considering the data in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the financial analyses, could create a misleading or incomplete view of such financial analyses. Future results may be different from those described and such differences may be material. Approximate implied per share equity value reference ranges derived from the financial analyses described below were rounded to the nearest $0.05. For purposes of the financial analyses described below, (i) median adjusted EBITDA multiples and free cash flow yields observed in the selected public companies analyses excluded Chord and Enerplus, as applicable, (ii) the term “adjusted EBITDA” generally refers to earnings before interest, taxes, depreciation, depletion and amortization, adjusted for certain non-recurring and non-cash items and (iii) the term “Wall Street commodity pricing” refers to Wall Street consensus commodity pricing, and the term “NYMEX commodity pricing” refers

75

to New York Mercantile Exchange strip commodity pricing, in each case as of February 13, 2024, and extrapolated commodity pricing per the management of Chord.

In calculating implied exchange ratio reference ranges as reflected in the financial analyses and certain additional information described below, other than the exchange ratio reference ranges implied by historical trading prices and Wall Street research analysts’ price targets for Chord common stock and Enerplus common shares, Citi divided the low-ends (or high-ends, as the case may be) of the approximate implied per share equity value reference ranges derived for Enerplus from such analyses and additional information, adjusted to account for the cash consideration, by the high-ends (or low-ends, as the case may be) of the approximate implied per share equity value reference ranges derived for Chord from such analyses and additional information in order to calculate the low-ends (or high-ends) of the implied exchange ratio reference ranges.

Selected Public Companies Analyses. Citi performed separate selected public companies analyses of Enerplus and Chord in which Citi reviewed certain financial and stock market information relating to Enerplus, Chord and the selected publicly traded companies listed below.

Enerplus. In its selected public companies analysis of Enerplus, Citi reviewed certain financial and stock market information relating to Enerplus and the following six selected companies that Citi considered generally relevant for purposes of analysis as publicly traded liquids-weighted oil and gas exploration and production companies with public market capitalizations of less than $10 billion (collectively, the “Enerplus selected companies”):

• Chord Energy Corporation

• Civitas Resources, Inc.

• Magnolia Oil & Gas Corporation

• Matador Resources Company

• Permian Resources Corporation

• SM Energy Company

Citi reviewed, among other information, (i) enterprise values, calculated as implied equity values based on closing stock prices on February 20, 2024 plus total debt, preferred equity and non-controlling interests (as applicable) and less cash, cash equivalents and investments in unconsolidated affiliates (as applicable), as a multiple of calendar year 2024 estimated adjusted EBITDA, and (ii) calendar year 2024 estimated free cash flow as a percentage of implied equity values based on closing stock prices on February 20, 2024 (“free cash flow yields”). Financial data of the Enerplus selected companies were based on publicly available Wall Street research analysts’ estimates, public filings and other publicly available information. Financial data of Enerplus was based on publicly available Wall Street research analysts’ estimates, financial forecasts and other information and data, including future commodity price estimates and assumptions utilizing NYMEX commodity pricing, provided by the management of Chord, public filings and other publicly available information.

The overall low to high calendar year 2024 estimated adjusted EBITDA multiples and calendar year 2024 estimated free cash flow yields observed for the Enerplus selected companies were 3.1x to 4.8x (with a median of 4.2x) and 19.3% to 7.2% (with a median of 9.5%), respectively. Citi noted that the calendar year 2024 estimated adjusted EBITDA multiple and the calendar year 2024 estimated free cash flow yield observed for Enerplus were 3.7x and 9.5%, respectively, based on Wall Street research analysts’ estimates. Citi then applied a selected range of calendar year 2024 estimated adjusted EBITDA multiples derived from the Enerplus selected companies of 3.4x to 4.4x, and a selected range of calendar year 2024 estimated free cash flow yields derived from the Enerplus selected companies of 11.6% to 9.4%, to corresponding data of Enerplus, in each case based on the financial forecasts and other information and data relating to Enerplus, including the future commodity price estimates, provided by the management of Chord. This analysis indicated approximate implied equity value reference ranges for Enerplus of $15.30 to $20.05 per share based on calendar year 2024 estimated adjusted EBITDA multiples and $16.25 to $20.00 per share based on calendar year 2024 estimated free cash flow yields.

76

Chord. In its selected public companies analysis of Chord, Citi reviewed certain financial and stock market information relating to Chord and the following six selected companies that Citi considered generally relevant for purposes of analysis as publicly traded liquids-weighted oil and gas exploration and production companies with public market capitalizations of less than $10 billion (collectively, the “Chord selected companies”):

• Civitas Resources, Inc.

• Enerplus Corporation

• Magnolia Oil & Gas Corporation

• Matador Resources Company

• Permian Resources Corporation

• SM Energy Company

Citi reviewed the same information referred to above under “—Selected Public Companies Analyses—Enerplus.” Financial data of the Chord selected companies were based on publicly available Wall Street research analysts’ estimates, public filings and other publicly available information. Financial data of Chord was based on publicly available Wall Street research analysts’ estimates, financial forecasts and other information and data, including future commodity price estimates and assumptions utilizing NYMEX commodity pricing, provided by the management of Chord, public filings and other publicly available information.

The overall low to high calendar year 2024 estimated adjusted EBITDA multiples and calendar year 2024 estimated free cash flow yields observed for the Chord selected companies were the same as described above for the Enerplus selected companies under “—Selected Public Companies Analyses—Enerplus.” Citi noted that the calendar year 2024 estimated adjusted EBITDA multiple and calendar year 2024 estimated free cash flow yield observed for Chord were 3.8x and 11.6%, respectively, based on Wall Street research analysts’ estimates. Citi then applied the same selected range of calendar year 2024 estimated adjusted EBITDA multiples and the selected range of calendar year 2024 estimated free cash flow yields described above under “—Selected Public Companies Analyses—Enerplus” to corresponding data of Chord, in each case based on the financial forecasts and other information and data relating to Chord, including the future commodity price estimates, provided by the management of Chord. This analysis indicated approximate implied equity value reference ranges for Chord of $151.00 to $196.75 per share based on calendar year 2024 estimated adjusted EBITDA multiples and $164.25 to $202.05 per share based on calendar year 2024 estimated free cash flow yields.

Utilizing the approximate implied per share equity value reference ranges derived for Enerplus and Chord as described above, Citi calculated the following approximate implied exchange ratio reference ranges, as compared to the exchange ratio:

Implied Exchange Ratio Reference Ranges Based On:		Exchange Ratio
CY2024E Adjusted EBITDA	CY2024E Free Cash Flow
0.0684x – 0.1206x	0.0713x – 0.1105x	0.10125x

77

Selected Precedent Transactions Analysis. Using publicly available information, Citi reviewed financial data relating to the following 13 selected transactions that Citi considered generally relevant for purposes of analysis as transactions involving publicly traded liquids-weighted oil and gas exploration and production target companies and transaction values of less than $10 billion (collectively, the “selected transactions”):

Citi reviewed, among other information, transaction values of the selected transactions, calculated as implied equity values for the target companies involved in the selected transactions based on the consideration paid in the applicable selected transaction plus total debt, preferred equity and non-controlling interests (as applicable) and less cash, cash equivalents and investments in unconsolidated affiliates (as applicable), as a multiple of the target company’s next 12 months estimated adjusted EBITDA. Financial data of the selected transactions were based on public filings and other publicly available information. Financial data of Enerplus was based on financial forecasts and other information and data, including future commodity price estimates and assumptions utilizing NYMEX commodity pricing, provided by the management of Chord, public filings and other publicly available information.

The overall low to high next 12 months estimated adjusted EBITDA multiples observed for the selected transactions was 2.7x to 5.7x (with a 25^th percentile of 3.2x, a 75^th percentile of 4.0x and a median of 3.5x). Citi then applied a selected range of next 12 months estimated adjusted EBITDA multiples of 3.2x to 4.0x derived from the selected transactions to the calendar year 2024 estimated adjusted EBITDA of Enerplus based on the financial forecasts and other information and data relating to Chord, including the future commodity price estimates, provided by the management of Chord. This analysis indicated an approximate implied equity value reference range for Enerplus of $14.35 to $18.30 per share, as compared to the implied value of the consideration of $18.42 per share based on the cash consideration of $1.84 per share and, for the stock consideration, the exchange ratio of 0.10125x and the closing price of Chord common stock on February 20, 2024 of $163.75 per share.

Discounted Cash Flow Analyses. Citi performed separate discounted cash flow analyses of Enerplus and Chord.

Enerplus. Citi performed a discounted cash flow analysis of Enerplus by calculating the estimated present value of the standalone unlevered, after-tax free cash flows that Enerplus was forecasted to generate during the fiscal years ending December 31, 2024 through December 31, 2028 based on financial forecasts and other information and data, including future commodity price estimates and assumptions utilizing NYMEX commodity pricing and Wall Street commodity pricing, provided by the management of Chord both before and after taking into account potential net synergies anticipated by the management of Chord to result from the arrangement. For purposes of this analysis, stock-based compensation was treated as a cash expense. Citi

78

calculated terminal values for Enerplus by applying to Enerplus’ fiscal year 2028 estimated adjusted EBITDA a selected range of adjusted EBITDA multiples of 2.75x to 3.5x. The present values (as of December 31, 2023) of the cash flows and terminal values and, as applicable, potential net synergies anticipated by the management of Chord to result from the arrangement were then calculated using a selected range of discount rates of 10.0% to 11.4%. This analysis indicated the following approximate implied equity value reference ranges for Enerplus based on future commodity price estimates and assumptions utilizing NYMEX commodity pricing and Wall Street commodity pricing, both before and after taking into account potential net synergies anticipated by the management of Chord to result from the arrangement:

• NYMEX commodity pricing: $15.50 to $18.85 per share (excluding potential net synergies) and $17.85 to $21.35 per share (including potential net synergies)

• Wall Street commodity pricing: $18.55 to $22.50 per share (excluding potential net synergies) and $20.90 to $25.05 per share (including potential net synergies)

Chord. Citi performed a discounted cash flow analysis of Chord by calculating the estimated present value of the standalone unlevered, after-tax free cash flows that Chord was forecasted to generate during the fiscal years ending December 31, 2024 through December 31, 2028 based on financial forecasts and other information and data, including future commodity price estimates and assumptions utilizing NYMEX commodity pricing and Wall Street commodity pricing, provided by the management of Chord. For purposes of this analysis, stock-based compensation was treated as a cash expense. Citi calculated terminal values for Chord by applying to Chord’s fiscal year 2028 estimated adjusted EBITDA a selected range of adjusted EBITDA multiples of 2.75x to 3.5x. The present values (as of December 31, 2023) of the cash flows and terminal values were then calculated using a selected range of discount rates of 10.0% to 11.4%. This analysis indicated approximate implied equity value reference ranges for Chord based on future commodity price estimates and assumptions utilizing NYMEX commodity pricing and Wall Street commodity pricing of $141.00 to $168.55 per share and $168.65 to $200.35 per share, respectively.

Utilizing the approximate implied per share equity value reference ranges derived for Enerplus and Chord as described above, Citi calculated the following implied exchange ratio reference ranges, as compared to the exchange ratio:

Implied Exchange Ratio Reference Ranges Based On:				Exchange Ratio
NYMEX Commodity Pricing (Excluding Potential Net Synergies)	NYMEX Commodity Pricing (Including Potential Net Synergies)	Wall Street Commodity Pricing (Excluding Potential Net Synergies)	Wall Street Commodity Pricing (Including Potential Net Synergies)
0.0810x – 0.1206x	0.0950x – 0.1384x	0.0834x – 0.1225x	0.0951x – 0.1376x	0.10125x

Net Asset Value Analyses. Citi performed separate net asset value analyses of Enerplus and Chord.

Enerplus. Citi performed a net asset value analysis of Enerplus by calculating the estimated present value of the standalone unlevered, after-tax free cash flows that Enerplus was forecasted to generate over the life of the oil and gas assets of Enerplus based on estimated oil and gas reserves and financial forecasts and other information and data, including future commodity price estimates and assumptions utilizing NYMEX commodity pricing and Wall Street commodity pricing, provided by the management of Chord both before and after taking into account potential net synergies anticipated by the management of Chord to result from the arrangement. The present values (as of December 31, 2023) of the cash flows and, as applicable, potential net synergies anticipated by the management of Chord to result from the arrangement were then calculated using a selected range of discount rates of 10.0% to 11.4%. This analysis indicated the following approximate implied equity value reference ranges

79

for Enerplus based on future commodity price estimates and assumptions utilizing NYMEX commodity pricing and Wall Street commodity pricing, both before and after taking into account potential net synergies anticipated by the management of Chord to result from the arrangement:

• NYMEX commodity pricing: $13.95 to $15.05 per share (excluding potential net synergies) and $16.15 to $17.40 per share (including potential net synergies)

0.0853x – 0.1001x	0.1008x – 0.1179x	0.0896x – 0.1048x	0.1026x – 0.1200x	0.10125x

Certain Additional Information

Citi also observed certain additional information that was not considered part of its financial analyses with respect to its opinion but was noted for informational purposes, including the following:

Illustrative Accretion (Dilution). Citi observed the illustrative potential pro forma financial effect of the arrangement on Chord’s fiscal years 2025, 2026 and 2027 estimated cash flow per share and estimated free cash flow per share, based on financial forecasts and other information and data relating to Chord and Enerplus, including future commodity price estimates and assumptions utilizing NYMEX commodity pricing and Wall Street commodity pricing, provided by the management of Chord, public filings and other publicly available information and after taking into account potential net synergies and transaction-related expenses anticipated by the management of Chord to result from the arrangement, which indicated that the arrangement could be accretive to Chord’s fiscal years 2025, 2026 and 2027 estimated cash flow per share and estimated free cash flow per share relative to Chord on a standalone basis. Actual results achieved by Chord may vary from forecasted results and variations may be material.

Illustrative Has/Gets. Citi compared the approximate implied per share equity value reference ranges derived for Chord on a standalone basis as described above under “—Discounted Cash Flow Analyses—Chord” and “—Net Asset Value Analyses—Chord” relative to illustrative approximate implied per share equity value reference ranges for Chord pro forma for the arrangement, utilizing the same selected ranges of adjusted EBITDA multiples and discount rates described above under “—Discounted Cash Flow Analyses” and after taking into account potential net synergies and transaction-related expenses anticipated by the management of Chord to result from the

80

arrangement. Citi observed that the arrangement could result in a potential uplift in the approximate implied equity value reference ranges for Chord relative to Chord on a standalone basis of (i) in the case of the discounted cash flow analyses, $146.60 to $174.55 per share (relative to $141.00 to $168.55 per share for Chord on a standalone basis) utilizing NYMEX commodity pricing and $173.25 to $208.05 per share (relative to $168.65 to $200.35 per share for Chord on a standalone basis) utilizing Wall Street commodity pricing and (ii) in the case of the net asset value analyses, $133.10 to $144.00 per share (relative to $131.95 to $141.90 per share for Chord on a standalone basis) utilizing NYMEX commodity pricing and $164.80 to $178.30 per share (relative to $161.30 to $173.65 per share for Chord on a standalone basis) utilizing Wall Street commodity pricing. Actual results achieved by Chord may vary from forecasted results and variations may be material.

Miscellaneous

Chord has agreed to pay Citi for its services in connection with the proposed arrangement an aggregate fee of $10 million, of which $2 million was payable upon delivery of Citi’s opinion and $8 million is payable contingent upon consummation of the arrangement. Citi also may be entitled to an additional fee of $1 million for its services payable at the sole discretion of Chord. In addition, Chord agreed to reimburse Citi for Citi’s expenses, including fees and expenses of counsel, and to indemnify Citi and related parties against certain liabilities, including liabilities under federal securities laws, arising out of Citi’s engagement.

As the Chord board of directors was aware, Citi and its affiliates in the past have provided, currently are providing and in the future may provide investment banking, commercial banking and other similar financial services to Chord and/or certain of its affiliates unrelated to the proposed arrangement, for which services Citi and its affiliates received and expect to receive compensation, including, during the approximate two-year period prior to the date of Citi’s opinion, having acted or acting as a lender under a credit facility of an affiliate of Chord, for which lending services Citi and its affiliates received no fees during such approximate two-year period. Although Citi and its affiliates did not provide investment banking, commercial banking or other similar financial services to Enerplus during the two-year period prior to the date of Citi’s opinion for which services Citi or its affiliates received or expect to receive compensation, Citi and its affiliates in the future may provide such services to Enerplus and/or its affiliates for which services Citi and its affiliates would expect to receive compensation. In the ordinary course of business, Citi and its affiliates may actively trade or hold the securities or financial instruments (including loans and other obligations) of Chord, Enerplus and their respective affiliates for their own account or for the account of customers and, accordingly, may at any time hold a long or short position or otherwise effect transactions in such securities or financial instruments. In addition, Citi and its affiliates (including Citigroup Inc. and its affiliates) may maintain relationships with Chord, Enerplus and their respective affiliates.

Chord selected Citi to act as Chord’s financial advisor in connection with the proposed arrangement based on Citi’s reputation, experience and familiarity with Chord, Enerplus and their respective businesses. Citi is an internationally recognized investment banking firm that regularly engages in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes.

Certain Unaudited Prospective Financial and Operating Information

Chord does not, as a matter of course, make public long-term forecasts or projections as to future performance, revenues, production, earnings or other results given, among other reasons, the uncertainty of the underlying assumptions and estimates. However, in connection with the arrangement, Chord management prepared and provided to the Chord board of directors and Chord’s financial advisors (i) certain unaudited internal financial forecasts with respect to Chord on a stand-alone basis and (ii) certain unaudited financial forecasts with respect to Enerplus on a stand-alone basis utilizing information provided by Enerplus management and Chord management assumptions (collectively, the “Forecasted Financial Information”). Certain financial information underlying the Forecasted Financial Information was provided to Enerplus and its financial advisors.

81

The Forecasted Financial Information was not prepared with a view toward compliance with published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation or presentation of prospective financial information. The Forecasted Financial Information was provided by Chord to the Chord board of directors in connection with its evaluation of the arrangement and to Chord’s financial advisor, Citi, for its use and reliance in connection with its financial analyses and opinion as described in the section entitled “The Arrangement—Opinion of Financial Advisor to Chord.” The inclusion of this Forecasted Financial Information should not be regarded as an indication that Chord or its affiliates, officers, directors, advisors or other representatives or any other recipient of this Forecasted Financial Information considered, or now considers, it to be necessarily predictive of actual future performance or events, or that it should be construed as financial guidance, and such summary projections set forth below should not be relied on as such.

The Forecasted Financial Information includes non-GAAP financial measures, including Adjusted EBITDA (as defined below) and free cash flow. Please see the tables below for a description of how Chord defines these non-GAAP financial measures. Chord believes that Adjusted EBITDA provides information useful in assessing operating and financial performance across periods, while free cash flow provides a useful measure of available cash generated by operating activities for investing, to reduce leverage or make distributions. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in accordance with GAAP, and non-GAAP financial measures used by Chord may not be comparable to similarly titled measures used by other companies.

This Forecasted Financial Information was prepared for internal use and is subjective in many respects. While presented with numerical specificity, the Forecasted Financial Information reflects numerous estimates and assumptions that are inherently uncertain and may be beyond the control of the Chord management team, including, among others, Chord’s and/or Enerplus’ future results, oil and gas industry activity, commodity prices, demand for oil and natural gas, the availability of sufficient cash flow or financing to fund the exploration and development costs associated with their respective projected drilling programs, takeaway capacity and the availability of services in the areas in which Chord and Enerplus operate, general economic and regulatory conditions and other matters described in the sections entitled “Cautionary Statement Regarding Forward-Looking Statements,” “Where You Can Find More Information” and “Risk Factors.” The Forecasted Financial Information reflects both assumptions as to certain business decisions that are subject to change and, in many respects, subjective judgment, and thus is susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. None of Chord nor its affiliates, officers, directors, advisors or other representatives can give assurance that the Forecasted Financial Information and the underlying estimates and assumptions will be realized. This Forecasted Financial Information constitutes “forward-looking statements” and actual results may differ materially and adversely from those set forth below.

The Forecasted Financial Information included in this proxy statement has been prepared by, and is the responsibility of, Chord management. Neither Chord’s independent registered public accounting firm, PricewaterhouseCoopers, nor any other independent registered public accounting firm, including Enerplus’ independent registered public accounting firm, KPMG, have audited, reviewed, examined, compiled or applied agreed-upon procedures with respect to the accompanying Forecasted Financial Information and, accordingly, PricewaterhouseCoopers and KPMG do not express an opinion or any other form of assurance with respect thereto nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the prospective financial information.

The Forecasted Financial Information does not take into account any circumstances or events occurring after the date on which it was prepared. Chord cannot give assurance that, had the Forecasted Financial Information been prepared either as of the date of the arrangement agreement or as of the date of this proxy statement, similar estimates and assumptions would be used. Except as required by applicable securities laws, Chord does not intend to, and disclaims any obligation to, make publicly available any update or other revision to the Forecasted Financial Information to reflect circumstances existing since its preparation or to reflect the occurrence of unanticipated events, even if any or all of the underlying assumptions are shown to be inappropriate, including

82

with respect to the accounting treatment of the arrangement under U.S. GAAP, or to reflect changes in general economic or industry conditions. The Forecasted Financial Information does not take into account all of the possible financial and other effects of the arrangement on Chord or Enerplus, the effect on Chord or Enerplus of any business or strategic decision or action that has been or will be taken as a result of the arrangement agreement having been executed, or the effect of any business or strategic decisions or actions that would likely have been taken if the arrangement agreement had not been executed, but which were instead altered, accelerated, postponed or not taken in anticipation of the arrangement. Further, the Forecasted Financial Information does not take into account the effect on Chord or Enerplus of any possible failure of the arrangement to occur. None of Chord, Enerplus or their respective affiliates, officers, directors, advisors or other representatives has made, makes or is authorized in the future to make any representation to any Chord stockholder or Enerplus shareholder or other person regarding Chord’s or Enerplus’ ultimate performance compared to the information contained in the Forecasted Financial Information or that the Forecasted Financial Information will be achieved. The inclusion of the Forecasted Financial Information herein should not be deemed an admission or representation by Chord, Enerplus or their respective affiliates, officers, directors, advisors or other representatives or any other person that it is viewed as material information of Chord or Enerplus, particularly in light of the inherent risks and uncertainties associated with such forecasts. The summary of the Forecasted Financial Information included below is not included in this proxy statement in order to influence any Chord stockholder’s decision or to induce any stockholder to vote in favor of any of the proposals at the Chord special meeting, but is provided solely because it was made available to the Chord board of directors and Chord’s financial advisors in connection with the arrangement.

In light of the foregoing, and considering that the Chord special meeting will be held several months after the Forecasted Financial Information was prepared, and the uncertainties inherent in any forecasted information, Chord stockholders are cautioned not to place undue reliance on such information, and Chord urges you to review Chord’s and Enerplus’ most recent SEC filings for a description of Chord’s and Enerplus’ reported financial results included therein. See the section entitled “Where You Can Find More Information.”

In preparing the prospective financial and operating information described below, Chord management used the following oil and natural gas price assumptions, which were based on (1) New York Mercantile Exchange strip pricing (“NYMEX Strip”) and (2) Wall Street consensus pricing (“Wall Street Consensus”), as of February 13, 2024, with the exception of WTI Oil in the NYMEX Strip case for the fiscal year 2026 and onward, which were based on Chord management assumptions:

	2024E		2025E		2026E+
NYMEX Strip
WTI Oil ($/Bbl)	$	75.76	$	71.43	$	71.50
Henry Hub Gas ($/MMBtu)	$	2.33	$	3.42	$	3.76

WTI Oil ($/Bbl)	$	79.00	$	75.60	$	78.00
Henry Hub Gas ($/MMBtu)	$	3.00	$	3.70	$	4.00

The following tables set forth certain summarized prospective financial and operating information of Chord and Enerplus for the fiscal years 2024 through 2028 each on a stand-alone basis. In addition to different pricing scenarios based on the two oil and natural gas price assumptions indicated above, Chord management prepared the following forecasts for each of Enerplus and Chord.

Board of Directors Following the Arrangement

Chord has agreed with Enerplus that it will take all actions necessary to ensure that, as of the effective time, the Chord board of directors will consist of up to eleven members, of whom: (i) seven directors will be designated by Chord, which designees will consist of Daniel E. Brown, Chord’s President and Chief Executive Officer, and the following six independent directors: Susan M. Cunningham, Douglas E. Brooks, Samantha F. Holroyd, Kevin S. McCarthy, Anne Taylor and Marguerite N. Woung-Chapman, and (ii) up to four directors will be designated by Enerplus, which designees will consist of Hilary Foulkes, Chair of the Enerplus board of directors, Ian C. Dundas, Enerplus’ President and Chief Executive Officer, and the following two independent directors: Ward Polzin and Jeffrey Sheets. Susan M. Cunningham will continue as the chair of the Chord board of directors.

Mr. Dundas, effective as of immediately following the effective time, will serve as an advisor to the Chief Executive Officer of Chord pursuant to the Letter Agreement. It is expected that Mr. Dundas will serve in such role for the Term. In his role as an advisor to the Chief Executive Officer, Mr. Dundas will be eligible to receive an annual base salary of $500,000, less applicable withholdings and deductions. During the Term, Mr. Dundas will also serve as a member of the Chord board of directors. Mr. Dundas will not receive any additional compensation for his service as a member of the Chord board of directors. As soon as reasonably practicable following the effective time, Mr. Dundas will receive the Dundas RSU Award, pursuant to the equity compensation plan of Chord, with a grant date fair market value of $2,000,000. The Dundas RSU Award will fully vest on the last day of the Term, subject to Mr. Dundas’s continued employment through such date. For the duration of the Term, Mr. Dundas is required to maintain a minimum ownership of 25,000 shares of Chord common stock (in addition to the shares subject to the Dundas RSU Award). Under the Letter Agreement, Mr. Dundas may participate in outside business activities during the Term, so long as (i) after giving effect to the arrangement, such business activities are not in competition with Chord, Enerplus or any of their respective subsidiaries within the state of North Dakota during the Term, and (ii) Mr. Dundas does not disclose any confidential, competitively valuable, non-public or proprietary information to any person or entity, and does not use any such information except for the benefit of Chord and its subsidiaries.

Management Following the Arrangement

Chord anticipates that Mr. Brown will serve as Director, President and Chief Executive Officer of the combined company. The remainder of Chord’s leadership team will include Michael Lou, Executive Vice President, Chief Strategy Officer and Chief Commercial Officer, Richard Robuck, Chord’s Executive Vice President and Chief Financial Officer, Darrin Henke, Chord’s Executive Vice President and Chief Operating Officer and Shannon Kinney, Chord’s Executive Vice President, Chief Administrative Officer and General Counsel, who will continue to serve in the respective capacities in the combined company.

Interests of Chord Directors and Executive Officers in the Arrangement

In considering the recommendation of the Chord board of directors that you vote “FOR” each of the proposals, you should be aware that certain of Chord’s directors and executive officers have interests in the

85

arrangement that may be different from, or in addition to, those of Chord stockholders generally. The Chord board of directors was aware of and considered these interests when it approved the arrangement agreement and the transactions contemplated thereby and recommended that Chord stockholders vote “FOR” each of the proposals. Such interests include that certain current directors and executive officers of Chord are expected to continue as directors and executive officers of Chord following the consummation of the arrangement.

Accounting Treatment

Chord and Enerplus prepare their respective financial statements in accordance with U.S. GAAP. In accordance with FASB ASC 805, Business Combinations, Chord will be treated as the acquirer for accounting purposes and will account for the arrangement as an acquisition of a business, which requires the determination of the acquirer, the purchase price, the acquisition date, the fair value of assets and liabilities of the acquiree and the measurement of goodwill, if any.

Federal Securities Laws Consequences; Stock Transfer Restrictions

Exemption from the Registration Requirements of the Securities Act

The stock consideration pursuant to the arrangement, will not be registered under the Securities Act or the U.S. securities laws of any state of the United States and will be issued and exchanged in reliance upon the exemption from the registration requirements of the Securities Act pursuant to Section 3(a)(10) thereof. Section 3(a)(10) of the Securities Act exempts from the registration requirements under the Securities Act the issuance of securities which have been approved, after a hearing upon the substantive and procedural fairness of the terms and conditions of the relevant transaction, at which all persons to whom it is proposed the securities will be issued shall have the right to appear, by any court expressly authorized by law to grant such approval. Under the arrangement agreement, Enerplus will apply to the Court for an interim order in connection with the arrangement after informing the Court of the intention to rely upon the exemption from the registration requirements of the Securities Act pursuant to Section 3(a)(10) thereof, and permitting notice to all persons to which the stock consideration will be issuable. Following Enerplus’ receipt of the interim order, the Enerplus shareholder approval of the arrangement and a hearing at which such persons will have the right to appear and assuming the requisite approval of the stock issuance proposal is obtained at the meeting, Enerplus will seek a final order from the Court as to the substantive and procedural fairness of the plan of arrangement. Notwithstanding such final order, the arrangement does not become effective until filing of the articles of arrangement by Enerplus and the issuance of the stock consideration by Chord. Chord therefore anticipates that, if the plan of arrangement becomes effective under the terms and conditions described in the arrangement agreement (including the receipt of such final order from the Court), the issuance of the stock consideration to the Enerplus shareholders will be exempt from the registration requirements under the Securities Act pursuant to Section 3(a)(10) thereof.

Resales of Chord Common Stock After the Effective Time

The shares to be received by Enerplus shareholders in exchange for their Enerplus common shares pursuant to the arrangement will be freely transferable under U.S. securities laws, except by persons who are “affiliates” (as defined in Rule 144) of Chord after the effective time, or were “affiliates” of Chord within 90 days prior to the effective time. Persons who may be deemed to be “affiliates” of an issuer include individuals or entities that control, are controlled by, or are under common control with, the issuer, whether through the ownership of voting securities, by contract, or otherwise, and generally include executive officers and directors of the issuer as well as principal shareholders of the issuer.

Any resale of Chord common stock by such an “affiliate” or former “affiliate” may be subject to the registration requirements of the Securities Act, absent an exemption therefrom, such as the exemption contained in Rule 144.

86

Court Approvals

The arrangement requires approval by the Court under Section 193 of the ABCA. Enerplus must first obtain the interim order which will, among other things, authorize and direct Enerplus to call, hold and conduct the Enerplus shareholder meeting and submit the arrangement to the Enerplus shareholders for approval. Enerplus has scheduled an interim order hearing for April 23, 2024. Under the arrangement agreement, Enerplus is required to seek the final order as soon as reasonably practicable, but in any event not later than five business days following the later of the approval of the arrangement resolution by Enerplus shareholders at the Enerplus shareholder meeting and the approval of the stock issuance proposal, subject to the availability of the Court.

The plan of arrangement will be implemented pursuant to Section 193 of the ABCA, which provides that, where it is impractical to effect a transaction under any other provision of the ABCA, a corporation may apply to the Court for an order approving the arrangement proposed by such corporation. Pursuant to this section of the ABCA, such an application will be made by Enerplus for approval of the arrangement. The Court has broad discretion under the ABCA when making orders with respect to plans of arrangement and the Court will consider, among other things, the fairness and reasonableness of the arrangement, both from a substantive and a procedural point of view. The Court may approve the arrangement either as proposed or as amended in any manner the Court may direct, subject to compliance with such terms and conditions, if any, as the Court thinks fit. Depending upon the nature of any required amendments, Enerplus and/or Chord, each acting reasonably, may determine not to proceed with the transactions contemplated in the arrangement agreement. Prior to the hearing on the final order, the Court will be informed that the parties intend to rely on the exemption from the registration requirements under the Securities Act for the issuance of the stock consideration pursuant to the arrangement, provided by Section 3(a)(10) thereof on the basis of the final order. There can be no assurance that the Court will approve the arrangement.

Regulatory Approvals

Antitrust Clearance

The completion of the arrangement is subject to antitrust review in the United States. Under the HSR Act, and the rules promulgated thereunder, the arrangement cannot be completed until the parties to the arrangement agreement have given notification and furnished information to the FTC and the DOJ, and until the applicable waiting period has expired or has been terminated.

On March 6, 2024, Chord and Enerplus each filed a premerger notification and report form under the HSR Act. The waiting period with respect to the notification and report forms filed under the HSR Act expired at 11:59 p.m., Eastern Time, on April 5, 2024.

At any time before or after consummation of the transaction, the FTC or the DOJ, or any state, could take such action under antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the transaction or seeking the divestiture of substantial assets of Chord or Enerplus or their respective subsidiaries. Private parties may also seek to take legal action under antitrust laws under certain circumstances.

Investment Canada Act Approval

Under the Investment Canada Act, certain transactions involving the “acquisition of control” of a Canadian business by a non-Canadian are subject to review and cannot be implemented unless the responsible minister or ministers is satisfied or deemed to be satisfied a reviewable transaction.

The transactions contemplated by the arrangement agreement constitute a reviewable transaction under the Investment Canada Act.

87

Under the Investment Canada Act there is an initial 45-day review period (during which the reviewable transaction cannot be completed) which may be unilaterally extended by the minister for an additional 30 days, after which further extensions can only be made on the mutual agreement of the minister and the investor.

The prescribed factors to be considered by the minister in determining whether a reviewable transaction is likely to be of “net benefit” to Canada include, among other things, (i) the effect of the investment on the level and nature of economic activity in Canada (including the effect on employment, capital investment, resource processing, utilization of Canadian products and services and exports); (ii) the degree and significance of participation by Canadians in the acquired business and the industry in which the Canadian business forms a part; (iii) the effect of the investment on productivity, industrial efficiency, technological development, product innovation and product variety in Canada; (iv) the effect of the investment on competition within any industry in Canada; (v) the compatibility of the investment with national and provincial industrial, economic and cultural policies; and (vi) the contribution of the investment to Canada’s ability to compete in world markets. The minister will also consider, among other things, any binding written undertakings offered to His Majesty in right of Canada in determining whether a reviewable transaction is likely to be of “net benefit” to Canada.

If, following review, the minister is satisfied that a reviewable transaction is likely to be of “net benefit” to Canada, the minister is required to send a notice to that effect. If the minister does not send notice of approval within the initial 45-day period or the extended period, as the case may be, the minister is deemed to be satisfied that the reviewable transaction is likely to be of “net benefit” to Canada and shall send a notice to that effect.

If, following review, the minister is not satisfied that a reviewable transaction is likely to be of “net benefit” to Canada, the minister is required to send a notice to that effect, advising of the right to make further representations and submit (additional) undertakings within 30 days from the date of such notice or any further period that may be agreed to by the minister and investor.

Within a reasonable time after the expiry of the period for making representations and submitting undertakings, as described above, the minister shall send notice to the applicant that either the minister is satisfied that the investment is likely to be of “net benefit” to Canada or confirmation that the minister is not satisfied that the investment is likely to be of “net benefit” to Canada. In the latter case, the reviewable transaction may not be implemented. Pursuant to terms of the arrangement agreement, Investment Canada Act Approval will be obtained if the minister has sent a notice stating that the minister is satisfied that the transactions contemplated by the arrangement agreement are likely to be of net benefit to Canada, or the minister has been deemed, in accordance with the Investment Canada Act, to be satisfied that the transactions contemplated by the arrangement agreement are likely to be of “net benefit” to Canada.

Pursuant to the arrangement agreement, Chord submitted its application for review with the Foreign Investment Review and Economic Security Branch of Innovation, Science and Economic Development Canada on March 6, 2024. As of the date of this proxy statement, the review of the transactions contemplated by the arrangement agreement under the Investment Canada Act is ongoing, and the Investment Canada Act Approval required under the arrangement agreement has not been obtained.

Canadian Competition Act Approval

Part IX of the Competition Act requires that parties to notifiable transactions provide notifications to the commissioner where the applicable thresholds set out in Sections 109 and 110 of the Competition Act are met and no exemption applies. Subject to certain limited exceptions, a notifiable transaction cannot be completed until the Parties to the transaction have each submitted a notification to the commissioner and the applicable waiting period has expired, or has been terminated or waived by the commissioner.

The parties have jointly determined that none of the transactions contemplated by the arrangement agreement constitute a notifiable transaction, and as such no obligation to file notifications arises pursuant to Part IX of the Competition Act.

88

NYSE and TSX Delisting

The Enerplus common shares are listed and posted for trading on the NYSE and the TSX under the symbol “ERF.” Following the completion of the arrangement, the Enerplus common shares will be delisted from the NYSE and TSX as promptly as practicable.

Chord common stock is currently listed for trading on the Nasdaq under the trading symbol “CHRD.” It is a condition to the completion of the arrangement that the shares of Chord common stock to be issued to Enerplus shareholders in exchange for their Enerplus common shares pursuant to the arrangement be approved for listing on the Nasdaq. Accordingly, Chord has agreed to use commercially reasonable efforts to obtain approval of the listing of the stock consideration for trading on the Nasdaq. Chord will provide the required notice to the Nasdaq of the listing of the shares of Chord common stock to be issued in connection with the arrangement prior to the Closing.

Fees, Costs and Expenses

All fees, costs and expenses incurred in connection with the arrangement and the plan of arrangement will be paid by the party incurring those fees, costs or expenses. Pursuant to the arrangement agreement, however, certain termination fees or expense reimbursements are payable by Chord or Enerplus if the arrangement agreement is terminated under certain circumstances.

NO APPRAISAL RIGHTS

Under the DGCL, holders of shares of Chord common stock are not entitled to appraisal rights in connection with the arrangement or any of the matters to be acted on at the special meeting.

THE ARRANGEMENT AGREEMENT AND THE PLAN OF ARRANGEMENT

The summary of the material provisions of the arrangement agreement and the plan of arrangement below and elsewhere in this proxy statement is qualified in its entirety by reference to the arrangement agreement, a copy of which is attached to this proxy statement as Annex A, and the plan of arrangement which is attached as Exhibit A to the arrangement agreement. This summary may not contain all of the information about the arrangement agreement and the plan of arrangement that is important to you. We urge you to carefully read the arrangement agreement in its entirety, including all of its schedules, as it is the legal document governing the arrangement. The arrangement agreement contains representations and warranties that the parties have made to each other as of specific dates. The assertions embodied in the representations and warranties in the arrangement agreement were made solely for purposes of the arrangement agreement and the arrangement and agreements contemplated thereby among the parties thereto, and may be subject to important qualifications and limitations agreed to by the parties thereto in connection with negotiating the terms thereof. The representations and warranties may also be subject to a contractual standard of materiality different from those generally applicable to stockholders and reports and documents filed with the SEC, and the assertions embodied in the representations and warranties contained in the arrangement agreement (and summarized below) are qualified by information in disclosure letters provided by Enerplus to Chord and by Chord to Enerplus in connection with the signing of the arrangement agreement and by certain information contained in certain of Chord’s and Enerplus’ filings with the SEC. The disclosure letters and SEC filings contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the arrangement agreement. In addition, information concerning the subject matter of the representations and warranties may have changed or may change after February 21, 2024 and subsequent developments or new information qualifying a representation or warranty may have been included in this proxy statement. In addition, if specific material facts arise that contradict the representations and warranties in the arrangement agreement, Chord or Enerplus, as applicable, will disclose those material facts in the public filings that it makes with the SEC in accordance with, and to the extent required by, applicable law. Accordingly, the representations and warranties in the arrangement agreement, the plan of arrangement and their descriptions in this proxy statement should not be read alone, but instead should be read in conjunction with the other information contained in the reports, statements and filings Chord and Enerplus publicly file with the SEC. For more information, see the “Where You Can Find More Information” section of this proxy statement.

The Arrangement

The arrangement agreement provides that at the effective time, Canadian Sub will acquire all of the issued and outstanding Enerplus common shares in exchange for stock consideration and cash consideration, with Enerplus continuing as a wholly-owned subsidiary of Chord. The arrangement will be implemented under the ABCA and requires approval of (a) at least two-thirds of the votes cast by Enerplus shareholders who vote in person (online) or by proxy at the meeting of Enerplus shareholders and (b) the Court.

The arrangement will become effective at the effective time on the date shown in the certificate of arrangement. If the final order is granted, and all other conditions to completion of the arrangement as set out in the arrangement agreement are satisfied or waived (to the extent that such conditions are capable of being satisfied prior to the effective date and, if waived, are not prohibited from being waived), the parties will send to the registrar, for filing, the articles of arrangement and such other documents as may be required pursuant to the ABCA to give effect to the arrangement.

Consideration Received Pursuant to the Arrangement

At the effective time, each Enerplus shareholder (other than Enerplus common shares held by dissenting Enerplus shareholders) will receive (i) 0.10125 of a share of Chord common stock and (ii) $1.84 in cash, in exchange for each Enerplus common share they hold, subject to adjustment as set forth in the arrangement agreement and plan of arrangement, if applicable.

91

If certain changes to the Enerplus common shares or Chord common stock occur between the date of the arrangement agreement and prior to the effective time, the stock consideration and the cash consideration will be adjusted to reflect the economic effect of such changes, including (i) if the outstanding Enerplus common shares or shares of Chord common stock increase, decrease, change into or exchange for a different number of shares or different class of shares, in each case, by reason of any reclassification, recapitalization, stock split, combination or exchange of the issued and outstanding Enerplus common shares or shares of Chord common stock, as applicable, (ii) if any stock dividend or dividend payable in any other securities of Enerplus or Chord is declared with a record date for the payment of such dividend or (iii) if any cash dividend or other distribution is declared, set aside or paid to Enerplus shareholders or Chord stockholders of record as of a time prior to the effective time (except for regular quarterly dividends and any additional dividend made in accordance with the arrangement agreement).

Pursuant to the arrangement agreement, Enerplus may also declare, in addition to its regular quarterly dividends, an additional dividend prior to the Closing in an amount intended to equalize dividend payments to Enerplus shareholders on a per-share basis with dividends that holders of Chord common stock receive during the pendency of the arrangement, if any. To the extent the Enerplus common share dividends require a downward adjustment of the stock consideration and the cash consideration, such dividends will first reduce the cash consideration until such cash consideration is reduced to zero (0), with any remaining downward adjustments reducing the stock consideration.

No fractional shares of Chord common stock will be issued as part of the arrangement. Where the aggregate number of shares of Chord common stock to be issued to an Enerplus shareholder as stock consideration would result in a fraction of securities of Chord being issuable, the number of Chord common stock to be received by such Enerplus shareholder will be rounded to the nearest whole number of Chord common stock. Any fractional cash consideration payable to an Enerplus shareholder will be rounded down to the nearest whole cent.

At the effective time, on the terms and subject to the conditions of the arrangement agreement and the applicable equity incentive plan of Enerplus, each (i) restricted share unit granted pursuant to Share Award Incentive Plan, originally effective as of February 1, 2014 and subsequently amended and restated effective as of November 1, 2023 (the “share award incentive plan”); (ii) performance share unit granted pursuant to the share award incentive plan; (iii) restricted share unit granted to non-employee directors pursuant to the Restricted Share Unit Plan for Directors, originally effective as of November 6, 2019 and subsequently amended effective as of March 1, 2023 (the “restricted share unit plan for directors”); and (iv) deferred share unit granted to non-employee directors pursuant to the Deferred Share Unit Plan for Directors, originally effective as of December 31, 2010 and subsequently amended effective as of January 14, 2014, May 9, 2019 and March 1, 2023 (the “deferred share unit plan for directors”), in each case, will become fully vested and the holder thereof will receive a cash payment equal to the fair market value of such award. For employee held awards, the fair market value is determined by either (i) the volume weighted average trading price (“VWAP”) of Enerplus common shares on the TSX for the five trading days ending on the second trading day prior to the Effective Date; (ii) the VWAP of Enerplus common shares on the TSX for the five trading days immediately following the announcement of the arrangement; or (iii) a combination thereof, depending on the title of such employee. For director held awards, the fair market value is determined by the VWAP of Enerplus common shares on the TSX for the ten trading days immediately preceding the effective date.

Treatment of Enerplus Equity Awards in the Arrangement

Enerplus equity-based awards that are outstanding immediately prior to the effective time will be treated in accordance with the arrangement agreement and the applicable Enerplus equity incentive plan.

92

Enerplus Restricted Share Unit Awards

Each outstanding restricted share unit award granted pursuant to the share award incentive plan will become fully vested upon the effective time and the holder thereof will receive from Enerplus, at the effective time, a cash payment as follows:

• With respect to Ian C. Dundas, the current Chief Executive Officer of Enerplus, the amount of such cash payment will be equal to the number of restricted share units subject to such award, adjusted for certain dividends declared since the date of grant (excluding the additional dividend), multiplied by the volume weighted average trading price of Enerplus common shares on the TSX for the five trading days ending on the second trading day prior to the effective date (provided that, if such period includes any trading days that are “ex-dividend” with respect to an additional dividend that may be declared by Enerplus, then the relevant five-day trading period shall be the five (5) trading days immediately prior to such ex-dividend date).

• With respect to employees who are not named executive officers, the amount of such cash payment will be equal to the number of restricted share units subject to such award, adjusted for certain dividends declared since the date of grant (excluding the additional dividend), multiplied by the fair market value of the underlying Enerplus common share. The fair market value will be determined by the greater of (i) the VWAP of Enerplus common shares on the TSX for the five trading days ending on the second trading day prior to the effective date (provided that, if such period includes any trading days that are “ex-dividend” with respect to an additional dividend that may be declared by Enerplus, then the relevant five-day trading period shall be the five (5) trading days immediately prior to such ex-dividend date); and (ii) the VWAP of Enerplus common shares on the TSX for the five trading days immediately following the announcement of the arrangement (in the case of clause (ii), excluding dividends declared following the announcement).

• With respect to named executive officers other than Ian C. Dundas, the amount of such cash payment will be equal to the sum of (i) 50% of the number of restricted share units subject to such award, adjusted for dividends declared between the date of grant and the announcement of the arrangement (excluding the additional dividend), multiplied by the VWAP of Enerplus common shares on the TSX for the five trading days immediately following the announcement of the arrangement and (ii) 50% of the number of restricted share units subject to such award, adjusted for certain dividends declared since the date of grant and the announcement of the arrangement (excluding the additional dividend), multiplied by the VWAP of Enerplus common shares on the TSX for the five trading days ending on the second trading day prior to the effective date (provided that, if such period includes any trading days that are “ex-dividend” with respect to an additional dividend that may be declared by Enerplus, then the relevant five-day trading period shall be the five (5) trading days immediately prior to such ex-dividend date).

Enerplus Performance Share Unit Awards

Each outstanding performance share unit granted pursuant to the share award incentive plan will become fully vested upon the effective time and the holder thereof will receive from Enerplus, at the effective time, a cash payment as follows:

• With respect to Ian C. Dundas, the current Chief Executive Officer of Enerplus, the amount of such cash payment will be equal to the number of performance share units subject to such award, adjusted for certain dividends declared since the date of grant (excluding the additional dividend), multiplied by the VWAP of Enerplus common shares on the TSX for the five trading days ending on the second trading day prior to the effective date (provided that, if such period includes any trading days that are “ex-dividend” with respect to an additional dividend that may be declared by Enerplus, then the relevant five-day trading period shall be the five trading days immediately prior to such ex-dividend date), multiplied by two.

93

• With respect to employees who are not named executive officers, the amount of such cash payment will be equal to the number of performance share units subject to such award, adjusted for certain dividends declared since the date of grant (excluding the additional dividend), multiplied by the fair market value of the underlying Enerplus common share, multiplied by two. The fair market value will be determined by the greater of (i) the VWAP of Enerplus common shares on the TSX for the five trading days ending on the second trading day prior to the effective date (provided that, if such period includes any trading days that are “ex-dividend” with respect to an additional dividend that may be declared by Enerplus, then the relevant five-day trading period shall be the five trading days immediately prior to such ex-dividend date); or (ii) the VWAP of Enerplus common shares on the TSX for the five trading days immediately following the announcement of the arrangement (in the case of clause (ii), excluding dividends declared following the announcement).

• With respect to named executive officers other than Ian C. Dundas, the amount of such cash payment will be equal to the sum of (i) (a) 50% of the number of performance share units subject to such award, adjusted for dividends declared between the date of grant and the announcement of the arrangement (excluding the additional dividend), multiplied by (b) a “Payout Multiplier” of 2.0, multiplied by (c) the VWAP of Enerplus common share on the TSX for the five trading days immediately following the announcement of the arrangement and (ii) (a) 50% of the number of performance share units subject to such award, adjusted for certain dividends declared since the date of grant (excluding the additional dividend), multiplied by (b) a “Payout Multiplier” of 2.0, multiplied by (c) the VWAP of Enerplus common share on the TSX for the five trading days ending on the second trading day prior to the effective date (provided that, if such period includes any trading days that are “ex-dividend” with respect to an additional dividend that may be declared by Enerplus, then the relevant five-day trading period shall be the five trading days immediately prior to such ex-dividend date).

Enerplus Director Restricted Share Unit Awards

Each restricted share unit award granted to a non-employee director of Enerplus pursuant to the restricted share unit plan for directors subject to time-based vesting that is outstanding as of immediately prior to the effective time, whether vested or unvested, will as of the effective time, become fully vested and the holder thereof will receive from Enerplus, at the effective time, a cash payment. Such cash payment will be equal to the number of restricted share units subject to such restricted share unit award, adjusted for certain dividends declared since the date of grant (excluding the additional dividend), multiplied by the VWAP of Enerplus common shares on the TSX for the ten trading days immediately preceding the effective date (provided that, if such period includes any trading days that are “ex-dividend” with respect to an additional dividend that may be declared by Enerplus, then the relevant ten-day trading period shall be the ten trading days immediately prior to such ex-dividend date).

Enerplus Director Deferred Share Unit Awards

Each deferred share unit award granted pursuant to the deferred share unit plan for directors that is outstanding as of immediately prior to the effective time will, as of the effective time, become eligible for settlement and the holder thereof will receive from Enerplus, at the effective time, a cash payment. Such cash payment will be equal to the number of deferred share units subject to such deferred share unit award, adjusted for certain dividends declared since the date of grant (excluding the additional dividend), multiplied by the VWAP of Enerplus common shares on the TSX for the ten trading days immediately preceding the effective date (provided that, if such period includes any trading days that are “ex dividend” with respect to an additional dividend that may be declared by Enerplus, then the relevant ten-day trading period shall be the ten trading days immediately prior to such ex-dividend date).

Dissent Rights of Enerplus Shareholders

Registered Enerplus shareholders may exercise rights of dissent with respect to the Enerplus common shares held by such Enerplus shareholders pursuant to Section 191 of the ABCA, as modified by the Court’s interim

94

order, final order and the plan of arrangement. The payment made to an Enerplus shareholder exercising dissent rights will be reduced by the portion of the additional dividend that the Enerplus shareholder has received (or is entitled to receive), if any.

None of the following will be entitled to exercise dissent rights: (i) a person who is not a registered holder of Enerplus common shares, (ii) Enerplus shareholders who vote or have instructed a proxyholder to vote their Enerplus common shares in favor of the arrangement resolution or (iii) an Enerplus shareholder who has not complied with the dissent right procedures or who withdrew such exercise prior to the effective time.

Deposit of Consideration

Chord and Enerplus expect to appoint TSX Trust Company to act as depositary to handle the payment of the cash consideration and the exchange of Enerplus common shares for shares of Chord common stock. Following receipt by Enerplus of the Court’s final order and prior to the effective time, Enerplus and Canadian Sub will deliver or cause to be delivered to the depositary such number of shares of Chord common stock and such cash to satisfy the aggregate consideration payable to Enerplus shareholders in accordance with the plan of arrangement which shares of Chord common stock and which cash will be held by the depositary as agent and nominee for such former Enerplus shareholders for distribution to them in accordance with the plan of arrangement.

Upon surrender to the depositary for cancellation of a certificate or DRS Advice which immediately prior to the effective time represented outstanding Enerplus common shares that were transferred pursuant to the plan of arrangement, together with a duly completed and executed letter of transmittal and any such additional documents and instruments as the depositary may reasonably require, the registered holder of such Enerplus common shares represented by such surrendered certificate or DRS Advice will be entitled to receive the corresponding stock consideration and cash consideration, less any amounts withheld pursuant to the plan of arrangement and any certificate or DRS Advice so surrendered will be cancelled.

After the effective time and until surrendered for cancellation, each certificate or DRS Advice that immediately prior to the effective time represented one or more outstanding Enerplus common shares (other than Enerplus common shares held by dissenting Enerplus shareholders) will be deemed at all times to represent only the right to receive in exchange therefor the consideration that the holder of such certificate or DRS Advice is entitled to receive in accordance with the plan of arrangement.

Efforts to Obtain Required Enerplus Shareholder Approval

Enerplus is required to take all action necessary in accordance with applicable laws and its organizational documents to duly give notice of, convene and hold a meeting of its shareholders for the purpose of obtaining the requisite approval of its shareholders relating to the arrangement, to be held as promptly as reasonably practicable following the clearance of this proxy statement by the SEC (and in any event will use reasonable best efforts to convene such meeting within 45 days thereof).

Notwithstanding the forgoing, Enerplus will be required to adjourn or postpone its shareholder meeting if required by applicable law or as required for quorum purposes and may adjourn or postpone its shareholder meeting (i) if there are insufficient shares of Enerplus common shares represented (in person (online) or by proxy) at the time of such meeting to obtain the requisite approval of Enerplus shareholders relating to the arrangement or (ii) if Enerplus determines that additional information needs to be added to the applicable proxy statement or circular with Chord’s prior written consent or as necessary to comply with applicable securities laws.

Unless the Enerplus board of directors has modified its recommendation regarding the arrangement as permitted under the arrangement agreement, Enerplus will include in its circular the unanimous recommendation of the Enerplus board of directors to the Enerplus shareholders that they vote in favor of the arrangement resolution.

95

Efforts to Obtain Required Chord Stockholder Approval

Chord is required to take all action necessary in accordance with applicable laws and its organizational documents to schedule the special meeting for the purpose of obtaining the requisite approval of its stockholders relating to the stock issuance proposal, to be held as promptly as reasonably practicable following the clearance of this proxy statement by the SEC (and in any event will use reasonable best efforts to convene such meeting within 45 days thereof).

Notwithstanding the forgoing, Chord will be required to adjourn or postpone the special meeting if required by applicable law or as required for quorum purposes and may adjourn or postpone the special meeting (i) if there are insufficient shares of Chord common stock represented (in person (online) or by proxy) at the time of such meeting to obtain the requisite approval of Chord stockholders relating to the arrangement or (ii) if Chord determines that additional information needs to be added to the applicable proxy statement or circular either with Enerplus’ prior written consent or as necessary to comply with applicable securities laws.

Unless the Chord board of directors has modified its recommendation regarding the arrangement as permitted under the arrangement agreement, Chord will include in its proxy statement the unanimous recommendation of the Chord board of directors to the Chord stockholders that they vote in favor of the stock issuance proposal.

Final Court Approval

After the interim order of the Court has been obtained, the Enerplus shareholders have approved the arrangement and the Chord stockholders have approved the stock issuance proposal, Enerplus is required to puruse an application for the final order pursuant to Section 193(a) of the ABCA as soon as reasonably practicable, but in any event not later than five business days thereafter, subject to the availability of the Court. The Court will consider, among other things, the procedural and substantive fairness of the terms and conditions of the arrangement to the Enerplus shareholders.

Corporate Governance

Pursuant to the arrangement agreement, Chord is required to take all actions necessary or appropriate, including by causing the resignation of the directors effective immediately prior to, but conditioned on, the effective time, who will not be continuing as Chord designees, to ensure that as of the effective time the Chord board of directors will consist of: (i) the seven members designated by Chord: Daniel E. Brown, Susan M. Cunningham, Douglas E. Brooks, Samantha F. Holroyd, Kevin S. McCarthy, Anne Taylor and Marguerite N. Woung-Chapman; and (ii) four members designated by Enerplus: Ian C.

Non-Solicitation of Alternative Transactions and Change in Recommendation

Chord and Enerplus each have agreed that, except as contemplated by the arrangement agreement, neither they nor any of their subsidiaries will (and Chord and Enerplus will, and will cause each of their respective subsidiaries to, use reasonable best efforts to cause its and their respective representatives not to):

• directly or indirectly initiate or solicit, or knowingly encourage or knowingly facilitate (including by way of furnishing non-public information relating to Chord or Enerplus or any of their respective subsidiaries) any inquiries or the making or submission of any proposal that constitutes, or would reasonably be expected to lead to, an acquisition proposal, except as expressly permitted in the arrangement agreement;

• participate or engage in discussions or negotiations with, or disclose any non-public information or data relating to Chord or Enerplus or any of their subsidiaries or afford access to the properties, books or records of Chord or Enerplus or any of their respective subsidiaries with respect to, relating to, or in furtherance of, an acquisition proposal or any inquiry, proposal or offer that would reasonably be expected to lead to an acquisition proposal, unless (i) notice is provided to the other party, (ii) its board determines in good faith (after consultation with its financial advisor(s) and outside legal counsel) that such proposal could reasonably lead to a superior proposal and (iii) its board determines in good faith (after consultation with its outside legal counsel) that failure to participate in such discussions would be reasonably likely to be inconsistent with its fiduciary duties under applicable laws;

• accept an acquisition proposal or enter into any agreement, including any letter of intent, memorandum of understanding, agreement in principle, merger agreement, arrangement agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement, arrangement or understanding, (i) constituting or related to, or that would reasonably be expected to lead to, any acquisition proposal (other than an acceptable confidentiality agreement

107

permitted pursuant to the arrangement agreement) or (ii) requiring or which would reasonably be expected to cause Chord or Enerplus to abandon, terminate or fail to consummate the arrangement; or

• (i) withhold, withdraw or qualify (or amend or modify in a manner adverse to the other party), or publicly propose to withhold, withdraw or qualify (or amend or modify in a manner adverse to the other party), the approval or recommendation or declaration of advisability, as applicable, by its board of directors or any such committee thereof of the arrangement agreement, the arrangement, this stock issuance proposal of Chord or the arrangement resolution of Enerplus, as applicable, (ii) endorse or recommend, adopt or approve, or propose publicly to endorse or recommend, adopt or approve any other acquisition proposal, (iii) fail to include the board recommendation in its proxy statement or circular, as applicable, (iv) (x) as to Chord, in response to an acquisition proposal that is structured as a tender offer or exchange offer pursuant to Rule 14d-2 under the Exchange Act for outstanding shares of Chord common stock (other than by Enerplus or an affiliate of Enerplus), fail to recommend, in a solicitation/recommendation statement on Schedule 14D-9, against acceptance of such tender offer or exchange offer by the Chord stockholders on or prior to the earlier of (1) three (3) business days prior to the date of the special meeting or (2) ten (10) business days (as such term is used in Rule 14d-9 of the Exchange Act) after commencement of such tender offer or exchange offer, or (y) as to Enerplus, in response to an acquisition proposal that is structured as a takeover bid, fail to recommend, in a directors’ circular prepared by Enerplus, against acceptance of such takeover bid on or prior to the earlier of (1) three (3) business days prior to the date of the Enerplus shareholder meeting or (2) fifteen (15) days after the formal commencement of such takeover bid, (v) if an acquisition proposal has been publicly announced or disclosed (other than pursuant to the foregoing clause (iv)), fail to publicly reaffirm its board of director recommendation on or prior to the earlier of five (5) business days following the written request of the other party or three (3) business days prior to the date of its meeting or (vii) make any other public statement that is inconsistent in any material respect with its board of directors recommendation.

Prior to receipt of the approval of its stockholders or shareholders, as applicable, in response to a bona fide written acquisition proposal that did not result from a breach of its non-solicitation obligations under the arrangement agreement, and that its board of directors determines in good faith, after consultation with its financial advisor(s) and outside legal counsel, is a superior proposal and the failure to make an adverse recommendation change or terminate the arrangement agreement would be reasonably likely to be inconsistent with its fiduciary duties under applicable law, Chord or Enerplus board of directors, as applicable, may make an adverse recommendation change or terminate the arrangement agreement pursuant to its terms; provided, however, that it will not be entitled to exercise its right to make an adverse recommendation change in response to a superior proposal (x) until four (4) business days after it provides written notice to the other party advising the other party that it has received an acquisition proposal that its board of directors has determined in good faith, after consultation with its financial advisor(s) and outside legal counsel, constitutes a superior proposal, including a copy of such superior proposal specifying the material terms and conditions thereof and any applicable transaction and financing documents, and identifying the person or group making such superior proposal, (y) if during such four (4) business day period, the other party proposes any alternative transaction (including any modifications to the terms of the arrangement agreement), unless its board of directors determines in good faith (after consultation with its financial advisor(s) and outside legal counsel, and taking into account all financial, legal, and regulatory terms and conditions of such alternative transaction proposal) that such previous superior proposal remains a superior proposal, and (z) unless its board of directors, after consultation with outside legal counsel, determines that the failure to make an adverse recommendation change would be reasonably likely to be inconsistent with its fiduciary duties under applicable law.

108

Notwithstanding the foregoing, other than in connection with a superior proposal, at any time prior to receipt of the approval of its stockholders or shareholders, as applicable, in response to an intervening event that is not related to any acquisition proposal, each of the Chord and Enerplus board of directors may make an adverse recommendation change if it:

• determines in good faith, after consultation with its outside legal counsel and any other advisor it chooses to consult, that the failure to make such adverse recommendation change would be reasonably likely to be inconsistent with its fiduciary duties under applicable law; and

• provides written notice to the other party advising the other party that it is contemplating making an adverse recommendation change and specifying the material facts and information constituting the basis for such contemplated determination; provided, however, that (x) it may not make an adverse recommendation change until the fourth business day after receipt by the other party of the notice of change and (y) during such four (4) business day period, at the request of the other party, it will negotiate in good faith with respect to any changes or modifications to the arrangement agreement which would allow it not to make such adverse recommendation change in response thereto.

Pursuant to the arrangement agreement, each party agreed that in addition to the obligations of Enerplus and Chord set forth above, as promptly as practicable (and in any event within 24 hours) after receipt thereof, Enerplus or Chord, as applicable, will advise Chord or Enerplus, respectively, in writing of any request for information or any Enerplus acquisition proposal or Enerplus acquisition proposal (as applicable) received from any person, or any inquiry, discussions or negotiations with respect to any Enerplus acquisition proposal or Chord acquisition proposal (as applicable) and the terms and conditions of such request, Enerplus acquisition proposal or Chord acquisition proposal (as applicable), inquiry, discussions or negotiations, and Enerplus or Chord (as applicable) will promptly provide to Enerplus or Chord, respectively, copies of any written materials received by Enerplus or Chord, as applicable, in connection with any of the foregoing, and the identity of the person or group making any such request, Enerplus acquisition proposal or Chord acquisition proposal (as applicable) or inquiry or with whom any discussions or negotiations are taking place. Each of Enerplus and Chord agreed that it will simultaneously provide to the other any non-public information concerning itself or its subsidiaries provided to any other person or group in connection with any Enerplus acquisition proposal or Chord acquisition proposal (as applicable) which was not previously provided to the other. Enerplus and Chord will promptly as practicable (and in any event within 24 hours) keep Enerplus and Chord, respectively, fully informed of the status of any Enerplus acquisition proposals or Chord acquisition proposals (as applicable) (including the identity of the parties and price involved and any changes to any material terms and conditions thereof). Each of Enerplus and Chord agreed not to release any third party from, or waive any provisions of, any confidentiality or standstill agreement to which it is a party with respect to a Enerplus acquisition proposal or Chord acquisition proposal (as applicable).

Enerplus and Chord further agreed that each will (and will cause its subsidiaries and use all reasonable best efforts to cause their respective representatives to) cease and terminate any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any possible Enerplus acquisition proposal or Chord acquisition proposal, as applicable. Each of Enerplus and Chord agreed that it will (i) take the necessary steps to promptly inform its representatives involved in the transactions contemplated by the arrangement agreement of the obligations undertaken with respect to the foregoing and (ii) promptly request each person who has heretofore executed a confidentiality agreement in connection with such person’s consideration of a Enerplus acquisition proposal or Chord acquisition proposal, as applicable, to acquire such party or any material portion thereof to return or destroy (and request that any such destruction will be confirmed in writing by an officer of such person) all confidential information heretofore furnished to such person by or on its behalf.

Subject to the paragraph below, Enerplus has agreed that, upon the request of Chord, Enerplus will, and will cause its subsidiaries to, use reasonable best efforts to: (i) implement such reorganizations of their corporate structure, capital structure, business, operations and assets or such other transactions as Chord may request, acting reasonably, including amalgamations, liquidations, reorganizations, continuances (including commencing a continuance process), or share transfers or asset transfers (each a “pre-acquisition reorganization”), (ii) reasonably cooperate with Chord and its advisors to determine the nature of the pre-acquisition reorganizations that might be undertaken and the manner in which they would most effectively be undertaken; and (iii) reasonably cooperate with Chord and its advisors to seek to obtain any material consents, approvals, waivers

111

or similar authorizations, if any, which are reasonably required in connection with the pre-acquisition reorganization, provided that any out-of-pocket costs, fees or expenses (including taxes) of Enerplus or any of its subsidiaries associated therewith will be at Chord’s sole expense. In addition, following the entry into the arrangement agreement, Enerplus will keep Chord apprised of, and consult with Chord in advance of implementing, any reorganizations of the corporate structure of Enerplus and its subsidiaries or any reorganizations, restructurings, transactions or other actions by or among Enerplus and/or any of its subsidiaries.

Enerplus will not be obligated to implement any pre-acquisition reorganization unless such pre-acquisition reorganization:

• is not prejudicial to Enerplus or shareholders of Enerplus;

• does not impair the ability of Enerplus or Chord to consummate, and will not materially delay the consummation of, the arrangement, including to prevent the satisfaction of any conditions to Closing;

• does not reduce the stock consideration or cash consideration or change the form of stock consideration or cash consideration to be received by Enerplus shareholders (other than Enerplus shareholders exercising dissent rights), as applicable;

• can be effected as close as reasonably practicable to but prior or as of the Closing;

• does not require Enerplus or any of its subsidiaries to take any action that could reasonably be expected to result in any adverse tax or other adverse consequences to Enerplus shareholders (including any taxes being imposed on such persons) that are incrementally greater (by more than a de minimis amount) than the taxes or other consequences that would be imposed on such persons in connection with the arrangement in the absence of any action being taken pursuant to the foregoing paragraph;

• does not become effective unless Chord has waived or confirmed in writing the satisfaction of all conditions to closing in its favor, and has confirmed in writing that it is prepared to promptly and without condition proceed to effect the arrangement;

• does not require Enerplus to obtain the approval of any Enerplus shareholders or the Court; and

• would not result in the breach or violation of any contract to which Enerplus or any of its subsidiaries is a party (including Enerplus’ existing credit facilities or Enerplus’ definitive agreements providing for the issuance of its existing senior unsecured notes) where the necessary consents, waivers, approvals or similar authorizations have not been or cannot reasonably be obtained prior to the effective date.

Chord must provide written notice to Enerplus of any proposed pre-acquisition reorganization at least twenty (20) business days prior to the effective date (unless providing such notice less than twenty (20) business days prior to the effective date is not prejudicial to Enerplus, acting reasonably). Upon receipt of such notice, Enerplus and Chord will work cooperatively and use their reasonable best efforts, to prepare prior to the effective time all documentation necessary and do such other acts and things as are necessary to give effect to such pre-acquisition reorganization, including any amendment to the arrangement agreement or the plan of arrangement (provided that such amendments do not require Enerplus to obtain approval of the Court or the Enerplus shareholders).

Chord agrees that the implementation of any pre-acquisition reorganization upon request of Chord, by itself, will not be considered in determining whether a representation or warranty or covenant or agreement of Enerplus under the arrangement agreement has been breached (including where any such pre-acquisition reorganization requires the consent of any third party under a contract).

If the arrangement is not completed and the arrangement agreement is terminated, Chord will indemnify Enerplus or any of its subsidiaries undertaking such pre-acquisition reorganization forthwith for all losses and reasonable costs and expenses (including any professional fees and expenses and taxes) incurred by Enerplus or any of its subsidiaries in considering or effecting all or any pre-acquisition reorganization, and in connection with reversing or unwinding any pre-acquisition reorganization.

112

Other Covenants and Agreements

The arrangement agreement contains certain other covenants and agreements, including covenants relating to:

• the prepayment of Enerplus’ existing credit facility, assumption or redemption of Enerplus’ existing senior unsecured notes, matters relating to Enerplus’ derivative contracts and hedging activities and the treatment of Chord’s existing credit facility;

• cooperation between Enerplus and Chord in connection with public announcements and communications;

• cooperation between Enerplus and Chord in the preparation and filing of the circular and this proxy statement;

• cooperation between Enerplus and Chord in listing the stock consideration on the Nasdaq prior to the effective time;

• access by each party to certain information about the other party during the period prior to the effective time and the parties’ agreement to keep information exchanged confidential; and

• indemnification of directors and officers of Enerplus and Chord, as applicable, and its respective subsidiaries in respect of claims arising from facts or events which occurred on or prior to the effective time.

Certain Employee Matters

The arrangement agreement sets forth certain provisions relating to compensation and benefits of Enerplus employees that generally apply following the effective time. As used below, “continuing employee” refers to an Enerplus employee who is employed as of immediately prior to the effective time and who remains employed by Chord immediately following the effective time while “non-continuing employee” refers to an Enerplus employee who is employed as of immediately prior to the effective time and who is notified by Chord or Enerplus that such employee will not continue employment following the effective time or who elects to not continue employment following the effective time.

Enerplus Employment Agreements. Enerplus has entered into employment agreements with certain executive officers. The arrangement agreement provides that any payments under such employment agreements will be made in accordance with the terms thereof and Chord and Enerplus have acknowledged that the completion of the arrangement will constitute a change of control within the meaning of such employment agreements.

Compensation of Continuing Employees. Following the effective time, and for at least twelve (12) months thereafter (or, if earlier, the date of termination of employment of an applicable continuing employee), Chord shall provide each continuing employee (and each non-continuing employee who provides services to Chord following the effective time) with (i) annual base salaries or wage levels, as applicable, that are substantially the same or greater than that which such continuing employee was entitled immediately prior to the effective time and (ii) cash incentive opportunities (subject to the description set forth under “—Annual Cash Bonuses” below), target equity incentive and other employee benefits (excluding any defined benefit pension plan, or retiree or post-termination health or welfare benefits) that are substantially the same in the aggregate to that which other similarly-situated employees of Chord receive.

Annual Cash Bonuses. With respect to Enerplus’ annual cash bonus plan for calendar year 2024, all participants shall be entitled to receive an amount equal to 150% of the amount that otherwise would have been payable to each such participant in respect of target performance for calendar year 2024; provided that, notwithstanding the foregoing, any non-continuing employee shall only be entitled to receive an annual cash

113

bonus for calendar year 2024 equal to 150% of the amount that otherwise would have been payable to each such non-continuing employee in respect of target performance for calendar year 2024, prorated to reflect his or her partial year of service. To the extent the effective time occurs on or prior to September 30, 2024, such amount shall be paid by Chord to each such participant at the time it pays 2024 annual cash bonuses in the ordinary course of business. To the extent the effective time occurs on or after October 1, 2024, two-thirds of such amount shall be paid by Chord to each such participant at the time it pays 2024 annual cash bonuses in the ordinary course of business, and one-third of such amount shall be paid by Chord to each such participant on the date that is six (6) months following the effective time. Notwithstanding the foregoing, any amount that becomes payable to a non-continuing employee shall be paid as soon as practicable following such non-continuing employee’s date of termination but in no event later than 30 days thereafter.

Termination of Continuing Employees. If a continuing employee’s employment with Chord is terminated during the period commencing at the effective time and ending twelve (12) months following the effective time (the “Transition Period”) by Chord without cause, or if a continuing employee terminates his or her employment with Chord for good reason during the Transition Period, then such continuing employee shall be paid by Chord a lump sum cash severance payment in an amount equal to the greatest of: (A) an amount applicable to such continuing employee calculated with reference to Enerplus’ severance matrix provided to Chord, (B) nine (9) months of base salary or base wages, as applicable, and (C) the amount payable to such continuing employee pursuant to any employment, severance, change in control, retention and/or other agreement, if any, between Enerplus and a continuing employee. Any non-continuing employee who is employed by Chord during any portion of 2025 shall also receive an additional cash payment equal to 150% of the amount that otherwise would have been payable to each such non-continuing employee in respect of target performance for calendar year 2025, prorated to reflect his or her partial year of service.

Chord Benefit Plans. Chord shall provide service credit to each continuing employee under each Chord benefit plan for purposes of vesting, eligibility and entitlement benefits accrual (other than with respect to defined benefit pension benefits, retiree medical benefits or disability benefits or nonqualified deferred compensation plans) for such continuing employee’s service with Enerplus prior to the effective time.

Chord Medical Plans. Chord shall use reasonable best efforts to (i) waive any limitation on health coverage of any continuing employees or their dependents due to pre-existing conditions or waiting periods, active employment requirements and requirements to show evidence of good health under Chord benefit plans (or other post-effective time benefit plans, if applicable) to the extent such continuing employees or eligible dependents are covered under an analogous Enerplus benefit plan and (ii) give each continuing employee credit for the plan year in which the effective time occurs towards applicable deductibles or annual out-of-pocket limits for medical expenses incurred prior to the effective time for which payment has been made.

Enerplus 401(k) Plans. Prior to the effective time, if requested in writing by Chord, Enerplus shall cause any Enerplus plan intended to be qualified under Section 401(a) of the U.S. Internal Revenue Code of 1986, as amended, to be terminated. If such termination occurs, Chord shall take any and all reasonable actions to cause a Chord plan intended to be qualified under Section 401(a) of the U.S. Internal Revenue Code of 1986, as amended, to accept any eligible rollover distribution from such Enerplus plan to such Chord plan and cause each continuing employee to become a participant in such Chord plan (subject to applicable eligibility requirements, but after giving effect to the service crediting described in “—Chord Benefit Plans” above).

Conditions to Completion of the Arrangement

The respective obligations of Chord and Enerplus to consummate the arrangement are subject to the satisfaction of the following conditions at or prior to the effective time, any or all of which may be waived jointly by Chord and Enerplus, to the extent permitted by applicable law:

115

Termination of the Arrangement Agreement

Right to Terminate

The arrangement agreement may be terminated prior to the effective time, whether before or after receipt of the approval of Enerplus shareholders or Chord stockholders, as applicable, (i) by mutual written agreement of Chord and Enerplus or (ii) by either Chord or Enerplus if:

• at any time prior to the receipt of the requisite Enerplus shareholder vote or approval of the stock issuance proposal by the Chord stockholders, as applicable, the Enerplus or Chord board of directors, as applicable, or any committee thereof, will have made an adverse recommendation change;

• at any time prior to the receipt of the requisite Enerplus shareholder vote or approval of the stock issuance proposal by the Chord stockholders, there is a willful and material breach of the other party’s non-solicitation obligation other than in the case where (i) such breach is a result of an isolated action by a person that is a representative of such party (other than a director or officer of such party) who was not acting at the direction of such party, (ii) the breaching party promptly remedies such breach and (iii) the consummation of the arrangement is not materially impeded, interfered with or prevented as a result of such breach; or

116

Except as otherwise provided in the arrangement agreement, all fees, costs and expenses incurred by a party in connection with the arrangement and the plan of arrangement, including all costs, expenses and fees of the parties incurred prior to or after the effective date in connection with, or incidental to, the plan of arrangement, will be paid by the party incurring such fees, costs and expenses, whether or not the arrangement is completed.

At any time before the effective time, any party may extend the time for performance of any obligations, waive inaccuracies of the representations or warranties or compliance with the covenants or conditions, in each case, of any other party if set forth in writing.

118

PROPOSAL NO. 1 – THE STOCK ISSUANCE PROPOSAL

The Chord board of directors has unanimously adopted a resolution authorizing, approving, declaring advisable and recommending to Chord stockholders for their approval the issuance of shares of Chord common stock to Enerplus shareholders in connection with the arrangement.

Nasdaq Listing Rule 5635(a) requires stockholder approval prior to the issuance of securities in connection with the acquisition of stock or assets of another company that would result in (i) the issuance, or potential issuance, of shares of common stock (including upon the conversion or exercise of securities into common stock) (a) having voting power equal to or in excess of 20% of the voting power of the common stock outstanding prior to the issuance of the common stock or securities convertible into or exercisable for common stock or (b) in excess of 20% of the number of shares of common stock outstanding prior to the issuance of the common stock or securities convertible into or exercisable for common stock. The number of shares of Chord common stock to be issued to Enerplus shareholders as consideration for the arrangement will exceed 20% of the number of shares of Chord common stock outstanding before the issuance. Therefore, Nasdaq Listing Rule 5635(a) requires stockholder approval of the stock issuance proposal.

As of April 8, 2024, approximately 41,563,092 shares of Chord common stock were issued and outstanding. Upon the consummation of the arrangement, Enerplus shareholders would acquire an aggregate of up to approximately 20.7 million shares of Chord common stock, which represents approximately 49% of the shares of Chord common stock issued and outstanding prior to the consummation of the arrangement. Upon the consummation of the arrangement, Enerplus shareholders would represent approximately 33% of the shares of the combined company on a fully diluted basis. In the event the stock issuance proposal is approved by Chord stockholders but the arrangement agreement is terminated (without the arrangement being completed) prior to the issuance of shares of Chord common stock pursuant to the arrangement agreement, Chord will not issue any shares of Chord common stock as a result of the approval of the stock issuance proposal.

Approval by Chord stockholders of the issuance of shares of Chord common stock to Enerplus shareholders is a condition to the Closing and is necessary for Chord to issue the common stock to Enerplus at the Closing. Accordingly, if this Proposal No. 1 – The Stock Issuance Proposal is not approved at the special meeting, a condition to the Closing will not be satisfied and the arrangement will not be completed.

Required Vote

Assuming the presence of a quorum, approval of this proposal requires the affirmative vote of a majority of the voting power of shares of Chord common stock present in person (online) or represented by proxy and entitled to vote thereon at the special meeting. An abstention from voting on the stock issuance proposal will have the same effect as a vote “AGAINST” this stock issuance proposal. A broker non-vote will not be voted on the stock issuance proposal. The failure of a Chord stockholder to submit a proxy or vote at the special meeting will have no effect on the outcome of the stock issuance proposal.

The stock issuance proposal is not conditioned on the approval of any other proposals at the special meeting.

Board Recommendation

The Chord board of directors unanimously recommends that you vote “FOR” this stock issuance proposal.

119

PROPOSAL NO. 2 – THE CHARTER AMENDMENT PROPOSAL

The Chord board of directors has unanimously adopted a resolution authorizing, approving, declaring advisable and recommending to Chord stockholders for their approval Charter Amendment to increase the number of authorized shares of Chord common stock from 120,000,000 shares to 240,000,000 shares.

The Charter currently authorizes 120,000,000 shares of Chord common stock. The Chord board of directors believes that the increased number of authorized shares of Chord common stock contemplated by the Charter Amendment is important to the combined company in order for additional shares to be available for issuance from time to time, without further action or authorization by Chord stockholders (except as required by applicable law or the Nasdaq rules), if needed for such corporate purposes as may be determined by the Chord board of directors. The additional shares of Chord common stock authorized would be part of the existing class of Chord common stock and, if issued, would have the same rights and privileges as the shares of Chord common stock presently issued and outstanding.

As of April 8, 2024, Chord had an aggregate of 41,563,092 shares of Chord common stock issued and outstanding. Upon the consummation of the arrangement, Chord anticipates issuing up to 20,679,910 shares of Chord common stock, resulting in 62,243,002 shares of Chord common stock issued and outstanding, which represents approximately 52% of Chord’s authorized shares of Chord common stock. If the Chord stockholders do not approve the charter amendment proposal, the combined company would have 57,756,998 authorized shares of Chord common stock available for issuance following the consummation of the arrangement and would be limited in its ability to raise equity by issuing additional shares of Chord common stock among other things, unless it first obtains approval from its stockholders to amend the Charter to increase the number of authorized shares of Chord common stock. No assurance can be given that the combined company’s stockholders will approve an increase in the number of authorized shares of Chord common stock and, even if they approve such an increase, that the combined company will be able to raise equity by issuing additional shares of Chord common stock. If the combined company is unable to raise equity by issuing additional shares of Chord common stock, it could have a material adverse effect on the combined company’s business, financial condition, results of operations, cash flows and liquidity. In the event the charter amendment proposal is approved by Chord stockholders but the arrangement agreement is terminated (without the arrangement being completed), Chord will not adopt the Charter Amendment.

The Chord board of directors desires to increase the number of shares available for issuance in order to provide the combined company with flexibility for business and financial purposes. The additional shares may be used for various purposes without further stockholder approval. These purposes may include: (1) raising capital, if Chord has an appropriate opportunity, through offerings of Chord common stock or securities that are convertible into or exchangeable for shares of Chord common stock; (2) exchanges of Chord common stock or securities that are convertible into or exchangeable for shares of Chord common stock for other outstanding securities; (3) providing equity incentives to employees, officers, directors, consultants or advisors; (4) expanding Chord’s business through the acquisition of other businesses or assets; (5) stock splits, dividends, and similar transactions; and (6) other purposes.

Required Vote

Assuming the presence of a quorum, approval of this proposal requires the affirmative vote of a majority of the voting power of shares of Chord common stock entitled to vote thereon at the special meeting. An abstention from voting at the special meeting will have the same effect as a vote “AGAINST” this charter amendment proposal. Because brokers, banks, and other nominees have discretionary authority to vote on the charter amendment proposal, we do not expect broker non-votes in connection with the charter amendment proposal. The failure of a Chord stockholder to submit a proxy or vote at the special meeting will have the same effect as a vote “AGAINST” the charter amendment proposal.

120

The charter amendment proposal is not conditioned on the approval of any other proposals at the special meeting. However, adoption of the Charter Amendment is conditioned upon the Closing.

Board Recommendation

The Chord board of directors unanimously recommends that you vote “FOR” this charter amendment proposal.

121

PROPOSAL NO. 3 – THE ADJOURNMENT PROPOSAL

The Chord board of directors has unanimously adopted a resolution authorizing, approving, declaring advisable and recommending to Chord stockholders for their approval the adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes to approve the stock issuance proposal.

If the number of shares of Chord common stock present in person (online) or represented by proxy at the special meeting voting in favor of the stock issuance proposal is insufficient to approve the stock issuance proposal at the time of the special meeting, then Chord may move to adjourn the special meeting in order to enable the Chord board of directors to solicit additional proxies in respect of the stock issuance proposal. In that event, Chord stockholders will be asked to vote only upon the adjournment proposal, and not on the stock issuance proposal.

In this proposal, you are being asked to authorize the holder of any proxy solicited by the Chord board of directors to vote in favor of granting discretionary authority to the proxy or attorney-in-fact to adjourn the special meeting one or more times for the purpose of soliciting additional proxies. If Chord stockholders approve the adjournment proposal, Chord could adjourn the special meeting and any adjourned session of the special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from Chord stockholders that have previously returned properly executed proxies or authorized a proxy by using the Internet or telephone. Among other things, approval of the adjournment proposal could mean that, even if Chord has received proxies representing a sufficient number of votes against the stock issuance proposal such that the stock issuance proposal would be defeated, Chord could adjourn the special meeting without a vote on the stock issuance proposal and seek to obtain sufficient votes in favor of the stock issuance proposal to obtain approval of the stock issuance proposal.

Approval by Chord stockholders of the adjournment proposal is not a condition to the Closing.

Required Vote

Assuming the presence of a quorum, approval of this proposal requires the affirmative vote of a majority of the voting power of shares of Chord common stock present in person (online) or represented by proxy and entitled to vote thereon at the special meeting. An abstention from voting on the adjournment proposal will have the same effect as a vote “AGAINST” this adjournment proposal. A broker non-vote will not be voted on the adjournment proposal.

The adjournment proposal is not conditioned on the approval of any other proposals at the special meeting.

Board Recommendation

The Chord board of directors unanimously recommends that you vote “FOR” this adjournment proposal. The failure of a Chord stockholder to submit a proxy or vote at the special meeting will have no effect on the outcome of the adjournment proposal.

122

OTHER MATTERS

Other Matters For Action at the Special Meeting

As of the date of this proxy statement, the Chord board of directors knows of no matters that will be presented for consideration at the special meeting other than as described in this proxy statement.

Section 1.5 Certain Adjustments.

(a) Without limiting Section 4.1 or Section 4.2, if between the entry into this Agreement and the Effective Time, (i) the outstanding Company Common Shares or Parent Common Stock shall have been increased, decreased, changed into or exchanged for a different number of shares or different class, in each case, by reason of any reclassification, recapitalization, stock split, split-up, combination or exchange of shares, (ii) a stock dividend or dividend payable in any other securities of Company or Parent shall have been declared with a record date for the payment of such dividend within such period or (iii) any similar event shall have occurred, then the Share Exchange Ratio and the Cash Consideration shall be appropriately adjusted to provide the holders of Company Common Shares the same economic effect as contemplated by this Agreement prior to such event.

(b) Without limiting Section 4.1 or Section 4.2, except to the extent expressly permitted, contemplated or required by this Agreement (including pursuant to Section 4.2(b)(i) or this Section 1.5(b)), if, between the entry into this Agreement and the Effective Time, Company declares, sets aside or pays any dividend or other distribution to Company shareholders of record as of a time prior to the Effective Time, except for:

(i) stock dividends or dividends payable in other securities of the Company, which shall be subject to Section 1.5(a),

(ii) regular quarterly dividends per Company Common Share in an amount not exceeding $0.065 and otherwise paid in accordance with Section 4.24; and

(iii) an additional dividend which may be declared by Company in an amount (if there is any such positive amount) equal to, on a per share basis, (x) the product of (A) the aggregate amount of cash dividends declared by Parent per share of Parent Common Stock with a record date after the Parent First Quarter Dividends Record Date but prior to the Effective Time multiplied by (B) the Share Exchange Ratio, minus (y) the aggregate amount of cash dividends declared by Company per Company Common Share with a record date after the Company First Quarter Dividend Record Date but prior to the Effective Time (the “Additional Dividend”),

then the Consideration to be paid per Company Common Share shall be appropriately decreased to provide to Company shareholders the same economic effect as contemplated by this Agreement and the Arrangement prior to such action and as so decreased shall, from and after the date of such event, be the Consideration to be paid per Company Common Share. For greater certainty, and without limiting Section 4.1, if, after the entry into this Agreement but prior to the Effective Time, Company declares any dividend(s) (other than a dividend described in clause (i)) in excess of those described in clauses (ii) and (iii), (A) to the extent that the aggregate amount of such excess does not exceed the Cash Consideration, the Cash Consideration to be paid by Parent Canadian Sub shall be decreased by an amount equal to such excess, and (B) to the extent that such excess exceeds the Cash Consideration, the Cash Consideration shall be reduced to zero (0) and the Stock Consideration shall be decreased by the amount by which such excess exceeds the Cash Consideration (and, by extension, the Share Exchange Ratio shall be proportionately adjusted). For purposes of the foregoing calculation, the value of the Stock Consideration will be calculated based on the closing price of the Parent Common Stock on the NASDAQ on the last trading day prior to the Closing Date.

Section 1.6 Dissenting Shares. Prior to the Company Meeting, Company shall provide Parent with prompt (and in no event later than two Business Days after receipt of notice) written notice of any purported exercise or

(b) Prior to the Effective Time, Parent shall take all actions necessary or appropriate to cause the resignation of the directors serving on the Parent Board who are not Parent Designees (it being understood that such resignation shall not constitute a voluntary termination with respect to any director of Parent or its Subsidiaries) to become effective immediately prior to, but conditioned on, the Effective Time such that, after giving effect to such resignations, the Parent Board shall consist of the Parent Designees and the Company Designees.

A-31

Interim Order and the Final Order, contravene, conflict with or result in a breach or violation of any Law applicable to Parent or any of its Subsidiaries or any of their respective properties or assets, other than, in the case of clause (iii), any such contraventions, conflicts, violations, defaults, acceleration, losses, or Encumbrances that would not reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect.

As of their respective dates, each of the Parent SEC Documents, as amended, complied, or if not yet filed or furnished, will comply, as to form in all material respects with Applicable Securities Laws applicable to such Parent SEC Documents, and none of the Parent SEC Documents contained, when filed (or, if amended prior to the date of this Agreement, as of the date of such amendment with respect to those disclosures that are amended), or if filed with or furnished to the SEC subsequent to the entry into this Agreement, will contain any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(c) Parent has established and maintains a system of internal control over financial reporting and disclosure controls and procedures (as such terms are defined in Applicable Securities Laws); such disclosure controls and procedures are designed to ensure that material information relating to Parent, including its consolidated Subsidiaries, required to be disclosed by Parent in the reports that it files or submits under Applicable Securities Laws is accumulated and communicated to Parent’s principal executive officer and its principal financial officer to allow timely decisions regarding required disclosure; and such disclosure controls and procedures are effective to ensure that information required to be disclosed by Parent in the reports that it files or submits under Applicable Securities Laws is recorded, processed, summarized and reported within the time periods specified in Applicable Securities Laws, and further designed and maintained to provide reasonable assurance regarding the reliability of Parent’s financial reporting and the preparation of Parent financial statements for external purposes in accordance with GAAP. There is no significant deficiency or material

A-32

weakness in the design or operation of internal controls of financial reporting (as defined in Applicable Securities Laws) utilized by Parent or its Subsidiaries, and, since January 1, 2022, there has not been, any illegal act or fraud, whether or not material, that involves management or other employees who have a significant role in Parent’s internal controls.

A-51

respective Representatives in violation of this Section 4.3, shall be deemed to be a breach of this Agreement by Company. Notwithstanding anything to the contrary in this Agreement, prior to obtaining the Company Requisite Shareholder Vote, Company and its Representatives may, in response to a request therefor by a Person who has made an unsolicited bona fide written Company Acquisition Proposal after the date hereof that did not result from a breach of this Section 4.3 by Company or any of Company’s Subsidiaries or any of their respective Representatives, take any actions described in clause (ii) in the first sentence of this Section 4.3(a) with respect to a third party if (x) Company provides Parent the notice required by Section 4.3(b) with respect to such Company Acquisition Proposal, (y) the Company Board determines in good faith (after consultation with Company’s financial advisor(s) and outside legal counsel) that such proposal constitutes or could reasonably be expected to lead to a Company Superior Proposal (disregarding, for the purposes of such determination, any due diligence or access condition to which such Company Acquisition Proposal is subject) and (z) the Company Board determines in good faith (after consultation with Company’s outside legal counsel) that the failure to participate in such discussions or negotiations or to disclose such information or data to such third party would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law; provided that Company shall not deliver any information to such third party without first entering into an Acceptable Confidentiality Agreement with such third party.

(b) Except as otherwise provided in this Section 4.3(b) and Section 4.3(c), neither the Company Board nor any committee thereof shall directly or indirectly (A) withhold, withdraw or qualify (or amend or modify in a manner adverse to Parent or Parent Canadian Sub), or publicly propose to withhold, withdraw or qualify (or amend or modify in a manner adverse to Parent or Parent Canadian Sub), the approval or recommendation by the Company Board or any such committee thereof of this Agreement, the Arrangement or the Arrangement Resolution, (B) endorse or recommend, adopt or approve, or propose publicly to endorse or recommend, adopt or approve any Company Acquisition Proposal, (C) fail to include the Company Board Recommendation in the Company Circular, (D) in the case of a Company Acquisition Proposal that is structured as a takeover bid, fail to recommend, in a directors’ circular prepared by the Company, against acceptance of such takeover bid on or prior to the earlier of (1) three (3) Business Days prior to the date of the Company Meeting or (2) fifteen (15) days after the formal commencement of such takeover bid, (E) if a Company Acquisition Proposal shall been publicly announced or disclosed (other than pursuant to the foregoing clause (D)), fail to publicly reaffirm the Company Board Recommendation on or prior to the earlier of five (5) Business Days after Parent so requests in writing or three (3) Business Days prior to the date of the Company Meeting or (F) make any other public statement that is inconsistent in any material respect with the Company Board Recommendation (any action described in these clauses (A) to (F) being referred to as a “Company Adverse Recommendation Change”). Notwithstanding the foregoing, at any time prior to obtaining the Company Requisite Shareholder Vote, and subject to Company’s compliance in all material respects at all times with the provisions of this Section 4.3 and Section 4.6, in response to a bona fide written Company Acquisition Proposal submitted after the date hereof that did not result from a breach of this Section 4.3 by Company or any of Company’s Subsidiaries or any of their respective Representatives, and that the Company Board determines in good faith, after consultation with Company’s financial advisor(s) and outside legal counsel, is a Company Superior Proposal and the failure to make a Company Adverse Recommendation Change or terminate this Agreement would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law, the Company Board may make a Company Adverse Recommendation Change or terminate this Agreement pursuant to Section 6.1(d)(iv); provided, however, that Company shall not be entitled to exercise its right to make a Company Adverse Recommendation Change in response to a Company Superior Proposal (x) until four (4) Business Days after Company provides written notice to Parent (a “Company Notice”) advising Parent that the Company Board has received a Company Acquisition Proposal that the Company Board has determined in good faith, after consultation with Company’s financial advisor(s) and outside legal counsel, constitutes a Company Superior Proposal, including a copy of the proposed Company Superior Proposal specifying the material terms and conditions of such Company Superior Proposal and any applicable transaction and financing documents, and identifying the Person or group making such Company Superior Proposal, (y) if during such four (4) Business Day period, Parent proposes any alternative transaction (including any modifications to the terms of this Agreement), unless the Company Board determines in good faith (after consultation with Company’s financial advisor(s) and outside legal counsel, and

taking into account all financial, legal, and regulatory terms and conditions of such alternative transaction proposal) that such previous Company Superior Proposal remains a Company Superior Proposal (it being understood that any change in the financial or other material terms of such Company Superior Proposal shall require a new Company Notice and a new four (4) Business Day period under this Section 4.3(b), and (z) unless the Company Board, after consultation with outside legal counsel, determines that the failure to make a Company Adverse Recommendation Change would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law.

(c) Other than in connection with a Company Superior Proposal (which shall be subject to Section 4.3(b) and shall not be subject to this Section 4.3(c)), notwithstanding the first sentence of Section 4.3(b), at any time prior to obtaining the Company Requisite Shareholder Vote, and subject to Company’s compliance in all material respects at all times with the provisions of this Section 4.3 and Section 4.6, in response to a Company Intervening Event that is not related to any Company Acquisition Proposal, the Company Board may make a Company Adverse Recommendation Change described in clause (A) of the definition thereof if the Company Board (i) determines in good faith, after consultation with Company’s outside legal counsel and any other advisor it chooses to consult, that the failure to make such Company Adverse Recommendation Change would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law and (ii) provides written notice to Parent (a “Company Notice of Change”) advising Parent that the Company Board is contemplating making a Company Adverse Recommendation Change and specifying the material facts and information constituting the basis for such contemplated determination; provided, however, that (x) the Company Board may not make such a Company Adverse Recommendation Change until the fourth Business Day after receipt by Parent of the Company Notice of Change and (y) during such four (4) Business Day period, at the request of Parent, Company shall negotiate in good faith with respect to any changes or modifications to this Agreement which would allow the Company Board not to make such Company Adverse Recommendation Change in response thereto.

(d) Parent agrees that, except as expressly contemplated by this Agreement, neither it nor any of Parent’s Subsidiaries shall (and Parent shall, and shall cause each of Parent’s Subsidiaries to, use reasonable best efforts to cause its and their respective Representatives not to), (i) directly or indirectly initiate or solicit, or knowingly encourage or knowingly facilitate (including by way of furnishing non-public information relating to Parent or any of Parent’s Subsidiaries) any inquiries or the making or submission of any proposal that constitutes, or would reasonably be expected to lead to, a Parent Acquisition Proposal, (ii) participate or engage in discussions or negotiations with, or disclose any non-public information or data relating to Parent or any of Parent’s Subsidiaries or afford access to the properties, books or records of Parent or any of Parent’s Subsidiaries with respect to, relating to, or in furtherance of, a Parent Acquisition Proposal or any inquiry, proposal or offer that would reasonably be expected to lead to a Parent Acquisition Proposal, or (iii) accept a Parent Acquisition Proposal or enter into any agreement, including any letter of intent, memorandum of understanding, agreement in principle, merger agreement, arrangement agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement, arrangement or understanding, (A) constituting or related to, or that would reasonably be expected to lead to, any Parent Acquisition Proposal (other than an Acceptable Confidentiality Agreement permitted pursuant to this Section 4.3) or (B) requiring or which would reasonably be expected to cause Parent to abandon, terminate or fail to consummate the Arrangement. Any action, or failure to take action, that is taken at the request of or on the behalf of Parent or any of Parent’s Subsidiaries or by their respective Representatives in violation of this Section 4.3, shall be deemed to be a breach of this Agreement by Parent. Notwithstanding anything to the contrary in this Agreement, prior to obtaining Parent Stockholder Approval, Parent and its Representatives may, in response to a request therefor by a Person who has made an unsolicited bona fide written Parent Acquisition Proposal after the date hereof that did not result from a breach of this Section 4.3 by Parent or any of, Parent’s Subsidiaries or any of their respective Representatives may take any actions described in clause (ii) in the first sentence of this Section 4.3(d) with respect to a third party if (x) Parent provides Company the notice required by Section 4.3(e) with respect to such Parent Acquisition Proposal, (y) the Parent Board determines in good faith (after consultation with Parent’s financial advisor(s) and Parent’s outside legal counsel) that such proposal constitutes or could reasonably be expected to lead to a Parent Superior Proposal (disregarding, for the purposes of such determination, any due

A-53

diligence or access condition to which such Company Acquisition Proposal is subject) and (z) the Parent Board determines in good faith (after consultation with Parent’s outside legal counsel) that the failure to participate in such discussions or negotiations or to disclose such information or data to such third party would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law; provided that Parent shall not deliver any information to such third party without first entering into an Acceptable Confidentiality Agreement with such third party.

(e) Except as otherwise provided in this Section 4.3(e) and Section 4.3(f), neither the Parent Board nor any committee thereof shall directly or indirectly (A) withhold, withdraw or qualify (or amend or modify in a manner adverse to Company), or publicly propose to withhold, withdraw or qualify (or amend or modify in a manner adverse to Company), the approval, recommendation or declaration of advisability by the Parent Board or any such committee thereof of this Agreement or the Stock Issuance, (B) endorse or recommend, adopt or approve, or propose publicly to endorse or recommend, adopt or approve any Parent Acquisition Proposal, (C) fail to include the Parent Board Recommendation in the Parent Proxy Statement, (D) in the case of a Parent Acquisition Proposal that is structured as a tender offer or exchange offer pursuant to Rule 14d-2 under the Exchange Act for outstanding shares of Parent Common Stock (other than by Company or an Affiliate of Company), fail to recommend, in a Solicitation/Recommendation Statement on Schedule 14D-9, against acceptance of such tender offer or exchange offer by the Parent stockholders on or prior to the earlier of (1) three (3) Business Days prior to the date of the Parent Meeting or (2) ten (10) Business Days (as such term is used in Rule 14d-9 of the Exchange Act) after commencement of such tender offer or exchange offer, (E) if a Parent Acquisition Proposal shall been publicly announced or disclosed (other than pursuant to the foregoing clause (D)), fail to publicly reaffirm the Parent Board Recommendation on or prior to the earlier of five (5) Business Days after Company so requests in writing or three (3) Business Days prior to the date of the Parent Meeting or (F) make any other public statement that is inconsistent in any material respect with the Parent Board Recommendation (any action described in these clauses (A) to (F) being referred to as a “Parent Adverse Recommendation Change”). Notwithstanding the foregoing, at any time prior to obtaining the Parent Stockholder Approval, and subject to Parent’s compliance in all material respects at all times with the provisions of this Section 4.3 and Section 4.6, in response to a bona fide written Parent Acquisition Proposal submitted after the date hereof that did not result from a breach of this Section 4.3 by Parent or any of Parent’s Subsidiaries or any of their respective Representatives, and that the Parent Board determines in good faith, after consultation with Parent’s financial advisor(s) and outside legal counsel, is a Parent Superior Proposal and, after consultation with Parent’s outside legal counsel, the failure to make a Parent Adverse Recommendation Change or terminate this Agreement would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law, the Parent Board may make a Parent Adverse Recommendation Change or terminate this Agreement pursuant to Section 6.1(c)(iv); provided, however, that Parent shall not be entitled to exercise its right to make a Parent Adverse Recommendation Change in response to a Parent Superior Proposal (x) until four (4) Business Days after Parent provides written notice to Company (a “Parent Notice”) advising Company that the Parent Board has received a Parent Acquisition Proposal that the Parent Board has determined in good faith, after consultation with Parent’s financial advisor(s) and outside legal counsel, constitutes a Parent Superior Proposal, including a copy of the proposed Parent Superior Proposal specifying the material terms and conditions of such Parent Superior Proposal and any applicable transaction and financing documents, and identifying the Person or group making such Parent Superior Proposal, (y) if during such four (4) Business Day period, Company proposes any alternative transaction (including any modifications to the terms of this Agreement), unless the Parent Board determines in good faith (after consultation with Parent’s financial advisor(s) and outside legal counsel, and taking into account all financial, legal, and regulatory terms and conditions of such alternative transaction proposal) that such previous Parent Superior Proposal remains a Parent Superior Proposal (it being understood that any change in the financial or other material terms of such Parent Superior Proposal shall require a new Parent Notice and a new four (4) Business Day period under this Section 4.3(e), and (z) unless the Parent Board, after consultation with outside legal counsel, determines that the failure to make a Parent Adverse Recommendation Change would be reasonably likely to be inconsistent with its fiduciary duties under applicable Law.

Each of Parent and Company shall, as soon as practicable, (i) supply the other with any information which may be required in order to effectuate such filings and (ii) supply any additional information, documents and testimony which is required or requested by a Governmental Entity of any jurisdiction in connection with the Transactions. No Party shall, nor shall it permit its Subsidiaries or Affiliates to, independently participate in any substantive meeting or discussion, or engage in any meeting or discussion, with any Governmental Entity in respect to the Transactions without giving the other Party reasonable prior notice of the meeting or discussion and, unless prohibited by such Governmental Entity, the opportunity to attend and participate. The Parties will, and will cause their and Subsidiaries and Affiliates to, consult and cooperate with one another and permit the other Party or its counsel to review in advance any proposed oral or written communication (including emails) by such Party or its Subsidiaries or Affiliates to any Governmental Entity, including but not limited to communications in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or

A-61

submitted by or on behalf of any Party in connection with proceedings under or relating to the HSR Act, the Investment Canada Act, the Competition Act, other Regulatory Laws or any applicable state Laws in connection with the Arrangement, and consider in good faith any suggestions made by the other Party and its counsel. The Parties shall discuss in advance the strategy for obtaining any clearances required under any applicable Law in connection with this Agreement or the Transactions; provided, however, that Parent shall determine and direct such strategy and timing for obtaining any clearances required under antitrust or competition Laws after reasonably consulting with and considering in good faith all comments and advice of Company (and its counsel) and Parent shall take the lead in all meetings and communications with any Governmental Entity in connection with obtaining such clearances required under antitrust or competition Laws.

(f) Each of Company and Parent shall, and shall cause its Subsidiaries and Affiliates to, (i) give the other Party prompt notice of the commencement or threat of commencement of any Proceeding by or before any Governmental Entity with respect to the Arrangement or any of the other Transactions, (ii) keep the other Party informed as to the status of any such legal Proceeding or threat, (iii) promptly inform the other Party and provide the other Party copies of any communication to or from any Governmental Entity regarding the Transactions and (iv) use reasonable best efforts to (A) avoid, and if necessary, vigorously resist, defend against and contest (including through all available appeals), any threatened or pending Proceeding by or before any Governmental Entity seeking to prohibit, restrain, enjoin, delay or make illegal the consummation of any of the Transactions or challenging the Transactions as violative of any Regulatory Law and (B) have vacated, lifted, reversed or overturned any Order, whether temporary, preliminary or permanent, that is in effect and that prohibits, restrains, enjoins, delays or makes illegal the consummation of any of the Transactions.

(g) Each of Parent and Company shall, and shall cause their Subsidiaries and Affiliates to, take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to obtain as soon as reasonably possible, and in any event prior to the Termination Date, all consents, clearances, approvals and waiting period expirations or terminations from any Governmental Entity (other than the Net Benefit Approval, which is addressed in Section 4.8(h)) that are necessary, proper or advisable to consummate the Transactions, including by offering, proposing, negotiating, agreeing to, consenting to and effecting (i) the sale, transfer, divestiture or other disposal of any assets or businesses of Parent, Company and their respective Subsidiaries, (ii) the termination of existing relationships, contractual rights or obligations of Parent, Company and their respective Subsidiaries, (iii) the termination, amendment or modification of any venture or other arrangement of Parent, Company and their respective Subsidiaries, (iv) the creation of any relationships, contractual rights or obligations of Parent, Company and their respective Subsidiaries, (v) the effectuation of any other change or restructuring of Parent, Company and their respective Subsidiaries or (vi) any other remedy, condition or commitment of any kind (any of the actions described in the foregoing clauses (i) through (vi), a “Remedy Action”); provided, however, that Parent and its Subsidiaries shall not be required to, and Company and its Subsidiaries shall not, without the prior written consent of Parent, be permitted to offer to any Person to, take any Remedy Action that would or would reasonably be expected to have, individually or in the aggregate, a material adverse effect on the business, assets, financial condition or results of operations of Parent, Company and their respective Subsidiaries, taken as a whole, provided, further, that for this purpose, Parent, Company and their respective Subsidiaries, taken as a whole, shall be deemed a consolidated group of entities of the size and scale of a hypothetical company that is 100% of the size of Company and its Subsidiaries, taken as a whole, as of the date of this Agreement. Any Remedy Action shall be conditioned upon the consummation of the Transactions. Without limiting the generality of the foregoing, Company shall, and shall cause its Subsidiaries to, (i) reasonably cooperate with Parent, execute and deliver such further documents, certificates, agreements and instruments and take such other actions as may be reasonably requested by Parent to evidence or reflect the Transactions (including the execution and delivery of all documents, certificates, agreements and instruments reasonably necessary for all filings hereunder); (ii) give all notices (if any) required to be made and given in connection with the Arrangement and the other Transactions; and (iii) obtain each approval, consent, clearance, ratification, permission, waiver of authorization (including any authorization of a Governmental Entity) required to be obtained from parties to any material Contracts (if any) or required to be obtained (pursuant to any applicable Law or Contract, or otherwise) in connection with the Arrangement (provided, however, that

A-62

Company shall not be required to pay any fees or make any other payments to any such Person in order to obtain any such approval, consent, clearance, ratification, permission, waiver or authorization (other than normal filing fees imposed by Law)).

(h) With respect to the Net Benefit Approval, Parent shall, and shall cause its Subsidiaries and Affiliates to, use reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable, as soon as reasonably possible, to obtain the Net Benefit Approval in order to consummate the transactions prior to Termination Date. For the purposes of this Section 4.8(h). Parent’s reasonable best efforts means, if necessary to obtain the Net Benefit Approval, proposing and negotiating in good faith and agreeing to such customary undertakings to the Minister as are required to obtain the Net Benefit Approval, including, if necessary, taking account of the reasonable comments and recommendations provided by the Minister in revised undertakings that are proposed to the Minister. Notwithstanding any other term of this Agreement, Parent shall determine and direct all strategy related to obtaining the Net Benefit Approval after reasonably consulting with and considering in good faith all comments and advice of Company (and its counsel).

(i) Each of Parent and Company shall not, and shall cause their respective Subsidiaries and Affiliates not to, acquire or agree to acquire (by merging or consolidating with, or by purchasing a substantial portion of the assets of or equity in, or by any other manner) any Person or portion thereof, or otherwise acquire or agree to acquire any assets or business, if such agreement, acquisition or other transaction would reasonably be expected to materially delay or impede the receipt of any required approval, consent, clearance or authorization or the consummation of the Transactions or prevent the ability of the Parties to consummate the Transactions by the Termination Date.

Section 4.9 Employee Matters.

(a) Company Employment Agreements. The Parties agree that any payments under the Company Employment Agreements (whether to be made before or after Closing) will be made in accordance with the terms thereof, and Company has disclosed in Schedule 4.9(a) of the Company Disclosure Letter its best estimate of the amounts of any payments that would be made upon a termination of employment of the officers of Company party to the Company Employment Agreements (the “Company Officers”) based on the assumptions contained therein. The Parties acknowledge and agree that completion of the Arrangement will constitute a “Change of Control” (as defined in the Company Employment Agreements), and that, unless agreed to otherwise in writing by a particular Company Officer with respect to his or her employment, the employment of each of the Company Officers will, or will be deemed to, be terminated other than for “Just Cause” (as defined in the Company Employment Agreements) immediately following the Effective Time, such that each Company Officer shall be entitled to payment of the amounts payable to such Company Officer immediately following the Effective Time in the manner set forth in his or her Company Employment Agreement as a result of such termination, subject to all applicable deductions and withholdings and subject to the execution and delivery of a release provided by the Company Officers, substantially in the form of the release attached as a schedule to the Company Employment Agreements. Notwithstanding anything contained herein to the contrary, in the event that a Company Officer receives any payments described in this Section 4.9(a), such Company Officer shall not be entitled to receive any payments pursuant to Section 4.9(e).

(b) Assumption of Continuing Employees. Following the Effective Time, Parent shall be responsible for, or shall cause the applicable Subsidiary or Affiliate of Parent, including the Company and its Subsidiaries, to be responsible for, all liabilities and obligations relating to the employment, or termination of employment, of each employee of Company or any of its Subsidiaries who is employed as of immediately prior to the Effective Time and who remains employed by Parent or any of its Subsidiaries or Affiliates immediately following the Effective Time (including, for the avoidance of doubt, employees of Company or any of its Subsidiaries and any Company Officers not terminated on the Effective Date as contemplated in Section 4.9(a)) (collectively, “Continuing Employees”), including liabilities with respect to notice of termination (or pay in lieu thereof) and severance and other obligations set forth in this Agreement. Continuing Employees shall exclude any

A-63

Non-Continuing Employees. As used herein, “Non-Continuing Employee” shall mean any employee of Company or any of its Subsidiaries who is employed as of immediately prior to the Effective Time and who is either notified by Parent, the Company or any of their respective Affiliates that such employee will be a Non-Continuing Employee pursuant to Section 4.9(f)(i)(A) or who elects to become a Non-Continuing Employee pursuant to Section 4.9(f)(i)(B). Following the Effective Date, subject to Section 4.9(e)(ii), Parent covenants and agrees, or shall cause the applicable Subsidiary or Affiliate of Parent to covenant and agree, to recognize pursuant to the requirements of any applicable Law or contract all past service of any Continuing Employee with Company or any of its Subsidiaries, and any previously recognized service with any predecessor of Company or any of its Subsidiaries (including EnerMark Inc., Enerplus Global Energy Management Company and their respective predecessors), including for the purposes of determining any entitlements to salary, bonus, vacation, notice of termination (or pay in lieu thereof), severance, benefit plans, retirement plans and pensions plans. Prior to the Effective Time, Company shall provide each Continuing Employee (including for greater certainty any Non-Continuing Employee who provides services to Parent at any time during the Transition Period) with a letter of employment confirming the title, base salary, annual bonus and incentive awards targets and entitlements, credited years of past service, minimum severance commitments and post-Effective Time arrangements, in each case, as set forth in this Section 4.9.

(c) Compensation of Continuing Employees. Without limiting the generality of Section 4.9(b), following the Effective Time, and for at least twelve (12) months thereafter (or, if earlier, the date of termination of employment of an applicable Continuing Employee), Parent shall or shall cause the applicable Subsidiary of Parent, including the Company and its Subsidiaries, to provide each Continuing Employee (and any Non-Continuing Employee who provides services to Parent at any time during the Transition Period), with (i) annual base salaries or wage levels, as applicable, that are substantially the same or greater than that which such Continuing Employee was entitled immediately prior to the Effective Time and (ii) cash incentive opportunities (subject to Section 4.9(d) below), target equity incentive (subject to Section 4.9(f)(i)(D) below) and other employee benefits (excluding any defined benefit pension plan, or retiree or post-termination health or welfare benefits) that are substantially the same in the aggregate to that which other similarly-situated employees of Parent or the applicable Subsidiary of Parent receive; provided, however, that nothing in this Section 4.9(c) or elsewhere in this Agreement shall limit the right of Parent or the Company to (x) impair in any way the right of Parent or the applicable Subsidiary of Parent to terminate the employment of any Continuing Employee or give any Continuing Employees any right to continued employment, (y) except with respect to annual base salaries as described in clause (i) above, make such adjustments that are determined by Parent or the Company in good faith to be appropriate in order to create uniform compensation practices for Continuing Employees across all organizations of Parent and its Subsidiaries (including the Company), or (z) integrate the Company Benefit Plans with the Parent Benefit Plans or any other employee benefit plans, programs, or arrangements.

(d) Annual Cash Bonuses. With respect to the annual cash bonus plan for calendar year 2024, all participants shall be entitled to receive an amount equal to 150% of the amount that otherwise would have been payable to each such participant in respect of target performance for calendar year 2024 as made available by Company to Parent in the Company Data Room; provided that, notwithstanding the foregoing, any Non-Continuing Employee shall only be entitled to receive an annual cash bonus for calendar year 2024 equal to 150% of the amount that otherwise would have been payable to each such Non-Continuing Employee in respect of target performance for calendar year 2024, prorated to reflect his or her partial year of service. To the extent the Effective Time occurs on or prior to September 30, 2024, such amount shall be paid by Parent or its applicable Subsidiary to each such participant at the time it pays 2024 annual cash bonuses in the ordinary course of business. To the extent the Effective Time occurs on or after October 1, 2024, two-thirds of such amount shall be paid by Parent or its applicable Subsidiary to each such participant at the time it pays 2024 annual cash bonuses in the ordinary course of business, and one-third of such amount shall be paid by Parent or its applicable Subsidiary to each such participant on the date that is six (6) months following the Effective Date. Notwithstanding the foregoing, any amount that becomes payable to a Non-Continuing Employee under this Section 4.9(d) shall be paid as soon as practicable following such Non-Continuing Employee’s date of termination but in no event later than 30 days thereafter.

A-64

(e) Termination of Continuing Employees.

(i) If a Continuing Employee’s employment with Parent or any of its Subsidiaries or Affiliates (including Company or any of its Subsidiaries) is terminated during the period commencing at the Effective Time and ending twelve (12) months following the Effective Time (the “Transition Period”) by Parent or any of its Subsidiaries or Affiliates (including the Company and its Subsidiaries) without Cause, or if a Continuing Employee terminates his or her employment with Parent or any of its Subsidiaries or Affiliates (including the Company and its Subsidiaries) for Good Reason during the Transition Period, then such Continuing Employee shall be paid by Parent (or Parent shall cause to be paid) a lump sum cash severance payment in an amount equal to the greatest of: (A) an amount applicable to such Continuing Employee calculated with reference to the Company’s severance matrix set forth in Schedule 4.9(e) of the Company Disclosure Letter, (B) nine (9) months of base salary or base wages, as applicable, and (C) the amount payable to such Continuing Employee pursuant to any employment, severance, change in control, retention and/or other agreement that is a Company Benefit Plan (including a Company Employment Agreement), if any, between Company (or a Subsidiary thereof) and a Continuing Employee (the amount of such foregoing payment being the “Company Employee Termination Payment”). Any Non-Continuing Employee who is employed by the Company or Parent, or any of their respective Affiliates, during any portion of 2025 shall also receive an additional cash payment equal to 150% of the amount that otherwise would have been payable to each such Non-Continuing Employee in respect of target performance for calendar year 2025, prorated to reflect his or her partial year of service. Notwithstanding the foregoing or anything else in this Agreement to the contrary, this Section 4.9(e) shall not apply to any employee of Company or any of its Subsidiaries who commenced employment with the Company and its Subsidiaries on or following the date of this Agreement (the “New Hires”) and, for greater certainty, the Parent shall retain the discretion to determine the severance payments payable to such New Hires consistent with the severance practices of the Parent.

(ii) In order to facilitate the foregoing provisions of this Section 4.9(e), Company has disclosed in Schedule 4.9(e) of the Company Disclosure Letter the information to be used and applied by Parent (and Parent agrees to so use and apply such information) to determine the amount of any termination, severance, separation, change of control or similar payments which would be payable to all employees of Company and its Subsidiaries for such events (including for the purposes of the Company Employee Termination Payments), assuming the relevant conditions to the payment of such amounts pursuant to such obligations are satisfied (whether or not such conditions are actually met). Payment of any such severance amount required pursuant to this Section 4.9(e) shall be subject to such Continuing Employee’s execution (and non-revocation, if applicable) of a customary and reasonable waiver and release of claims in favor of Parent and its Subsidiaries and Affiliates (including the Company) in a form to be provided by Parent or its Subsidiaries.

(f) Continuing Employee Agreements.

(i) Within sixty (60) days following the Effective Date, Parent shall, or shall cause the Company and its Subsidiaries, to provide letters to each employee of Company or any of its Subsidiaries who is employed as of immediately prior to the Effective Time setting forth:

(A) Whether such employee will be a Continuing Employee or a Non-Continuing Employee;

(B) For Continuing Employees, the ability to choose whether to remain a Continuing Employee or opt to become a Non-Continuing Employee, provided that such choice must be irrevocably made during the ten (10)-day period following the delivery of such letter and provided further that any individual other than a New Hire who is either designated as a Non-Continuing Employee or chooses to become a Non-Continuing Employee shall be entitled to receive a Company Employee Termination Payment and any individual other than a New Hire who chooses to become a Continuing Employee will only be entitled to receive a Company Employee Termination Payment to the extent his or her employment with Parent or its Subsidiary is terminated by Parent or its applicable

A-65

Subsidiary without Cause or due to his or her resignation for Good Reason, in each case, within twelve (12) months following the Effective Date;

(C) For Non-Continuing Employees, including those who elect to become a Non-Continuing Employee, an estimated date of termination of employment (which, for the avoidance of doubt, shall not exceed twelve (12) months following the Effective Date); and

(D) Each Continuing Employee who elects to remain a Continuing Employee shall receive an equity award pursuant to Parent’s stock plan with a target value equal to sixty percent (60%) of the target value of an annual equity award granted to a similarly-situated employee of Parent.

(g) Parent shall, or shall cause the Company and its Subsidiaries, to honor and comply with their (including Company’s current) respective obligations under all employment, severance, change in control, retention and other agreements or other Company Benefit Plans, if any, between Company (or a Subsidiary thereof) and a Continuing Employee (including any severance provisions contained therein), including any Company Employment Agreements, it being understood that the foregoing shall not be construed to limit any amendments or terminations otherwise permitted by the terms of the applicable agreements.

(h) Parent Benefit Plans. Without limiting the final sentence of Section 4.9(b), following the Effective Time, Parent shall, or shall cause the Company and its Subsidiaries, to credit each Continuing Employee under each Parent Benefit Plan in which Continuing Employees may be eligible to participate after the Closing Date (the “Post-Closing Plans”), credit for purposes of vesting, eligibility and entitlement benefits accrual (other than for any purposes with respect to any defined benefit pension benefits, retiree medical benefits or disability benefits, or nonqualified deferred compensation plans) for such Continuing Employees’ full or partial years of service with Company or any of its Affiliates (including any predecessors) performed at any time prior to the Closing Date to the extent such service was taken into account under the analogous Company Benefit Plan in effect immediately prior to the Closing Date; provided, however, that no such prior service shall be taken into account to the extent it would result in the duplication of benefits to any Continuing Employee.

(i) Parent Medical Plans. Parent shall, or shall cause the Company and its Subsidiaries, to use reasonable best efforts to (i) waive any limitation on health coverage of any Continuing Employees or any of their covered, eligible dependents due to pre-existing conditions and/or waiting periods, active employment requirements and requirements to show evidence of good health under the applicable Post-Closing Plan to the extent such Continuing Employee or eligible dependents are covered under an analogous Company Benefit Plan immediately prior to the Closing Date, and such conditions, periods or requirements are satisfied or waived under such Company Benefit Plan and (ii) give each Continuing Employee credit for the plan year in which the Closing Date occurs towards applicable deductibles and annual out-of-pocket limits for medical expenses incurred prior to the Closing Date for which payment has been made, in each case, to the extent permitted by the applicable insurance plan provider and only to the extent such deductibles or limits for medical expenses were satisfied or did not apply under the analogous Company Benefit Plan in effect immediately prior to the Closing Date.

(j) Company 401(k) Plans. Prior to the Closing Date, if requested by Parent in writing at least three (3) days before the Closing, Company shall cause Company and its Subsidiaries to take all necessary and appropriate actions to cause (i) each Company Benefit Plan intended to be qualified under Section 401(a) of the Code (the “Company 401(k) Plan”) to be terminated and (ii) all participants to cease participating under the Company 401(k) Plan, in each case, effective no later than the Business Day preceding the Closing Date; provided, however, that such actions may be contingent upon Closing. Company shall provide Parent with an advance copy of all documentation necessary to effect this Section 4.9(j) and a reasonable opportunity to comment thereon prior to the adoption or execution thereof. In the event the Company 401(k) Plan is terminated as set forth in the preceding sentence, as soon as administratively practicable following the Effective Time, Parent shall take any and all reasonable actions as may be reasonably required, including amendments to a defined contribution retirement plan intended to be qualified under Section 401(a) of the Code designated by Parent (the “Parent 401(k) Plan”) to (A) cause the Parent 401(k) Plan to accept any “eligible rollover

A-66

distributions” (within the meaning of Section 402(c)(4) of the Code) in the form of cash in an amount equal to the full account balance distributed or distributable to such employee from the Company 401(k) Plan to the Parent 401(k) Plan, including any outstanding loans and (B) cause each Continuing Employee to become a participant in the Parent 401(k) Plan as of the Closing Date (subject to any applicable eligibility requirements, but giving effect to the service crediting provisions of Section 4.9(h)).

(k) General. Nothing in this Agreement shall constitute an establishment or termination of, or an amendment to, or be construed as establishing, terminating or amending, any Parent Benefit Plan, Company Benefit Plan, Post-Closing Plan or other Employee Benefit Plan sponsored, maintained or contributed to by Company, Parent or any of their respective Subsidiaries. The provisions of this Section 4.9 are for the sole benefit of the Parties and nothing herein, expressed or implied, is intended or will be construed to confer upon or give to any Person (including, for the avoidance of doubt, any current or former employee of Company, Parent or any of their respective Affiliates), other than the Parties and their respective permitted successors and assigns, any third party beneficiary, legal or equitable or other rights or remedies (including with respect to the matters provided for in this Section 4.9) under or by reason of any provision of this Section 4.9. Nothing in this Section 4.9 is intended to (i) prevent Parent, Company or any of their Affiliates from terminating the employment or service of any Person, including a Continuing Employee, at any time and for any reason, subject to compliance with the terms hereof, (ii) provide any Person any right to employment or service or continued employment or service with Parent or any of its Subsidiaries (including following the Effective Time, the Company and following the consummation of the Arrangement) or any particular term or condition of employment or service, or (iii) prevent Parent, Company or any of their Affiliates from terminating, revising or amending any Parent Benefit Plan, Company Benefit Plan, Post-Closing Plan or other Employee Benefit Plan sponsored, maintained or contributed to by Company, Parent or any of their respective Subsidiaries.

Section 4.10 Indemnification; Directors’ and Officers’ Insurance.

(a) Without limiting any other rights that any Indemnified Person may have pursuant to any employment agreement, indemnification agreement or Organizational Documents in effect on the date hereof or otherwise, from the Effective Time, Parent and the Company shall, jointly and severally, indemnify, defend and hold harmless, in the same manner as provided by Parent or Company, as applicable, immediately prior to the date of this Agreement, each Person who is now, or has been at any time prior to the date of this Agreement or who becomes prior to the Effective Time, a director or officer of Parent, Company or any of their respective Subsidiaries or who acts as a fiduciary under any Parent Benefit Plan or Company Benefit Plan or is or was serving at the request of Parent, Company or any of their respective Subsidiaries as a director, officer or fiduciary of another corporation, partnership, limited liability company, joint venture, Employee Benefit Plan, trust or other enterprise, in each case, when acting in such capacity (the “Indemnified Persons”) against all losses, claims, damages, costs, fines, penalties, expenses (including attorneys’ and other professionals’ fees and expenses), liabilities or judgments or amounts that are paid in settlement, of or incurred in connection with any threatened or actual Proceeding to which such Indemnified Person is a party or is otherwise involved (including as a witness) based, in whole or in part, on or arising, in whole or in part, out of the fact that such Person is or was a director or officer of Parent, Company or any of their respective Subsidiaries, a fiduciary under any Parent Benefit Plan or Company Benefit Plan or is or was serving at the request of Parent, Company or any of their respective Subsidiaries as a director, officer or fiduciary of another corporation, partnership, limited liability company, joint venture, Employee Benefit Plan, trust or other enterprise, as applicable, or by reason of anything done or not done by such Person in any such capacity, whether pertaining to any act or omission occurring or existing at or prior to, but not after, the Effective Time and whether asserted or claimed prior to, at or after the Effective Time (“Indemnified Liabilities”), including all Indemnified Liabilities based in whole or in part on, or arising in whole or in part out of, or pertaining to, this Agreement or the Transactions, in each case to the fullest extent permitted under applicable Law (and Parent and the Company shall, jointly and severally, pay expenses incurred in connection therewith, including but not limited to expenses for the retention of Company’s regularly engaged legal counsel or other counsel satisfactory to them, in advance of the final disposition of any such Proceeding to each Indemnified Person to the fullest extent permitted under applicable Law). Without limiting the foregoing, in

A-67

the event any such Proceeding is brought or threatened to be brought against any Indemnified Persons (whether arising before, at or after the Effective Time), (i) Parent and the Company shall pay all reasonable fees and expenses of one counsel for the Indemnified Persons as promptly as statements therefor are received, and (ii) Parent and the Company shall use their reasonable best efforts to assist in the defense of any such matter. Any Indemnified Person wishing to claim indemnification or advancement of expenses under this Section 4.10, upon learning of any such Proceeding, shall notify Parent and the Company (but the failure so to notify shall not relieve a Party from any obligations that it may have under this Section 4.10 except to the extent such failure materially prejudices such Party’s position with respect to such claims). With respect to any determination of whether any Indemnified Person is entitled to indemnification by Parent or Company under this Section 4.10, such Indemnified Person shall have the right, as contemplated by applicable Law, to require that such determination be made by special, independent legal counsel selected by the Indemnified Person and approved by Parent or Company, as applicable (which approval shall not be unreasonably withheld, conditioned or delayed), and who has not otherwise performed material services for Parent, Company or the Indemnified Person within the last three (3) years.

(b) Parent and the Company agree that, until the six (6) year anniversary date of the Effective Time, that none of Parent nor the Company shall amend, repeal or otherwise modify any provision in the Organizational Documents of Company or its Subsidiaries in any manner that would affect adversely the rights thereunder or under the Organizational Documents of Company or any of its Subsidiaries of any Indemnified Person to indemnification, exculpation and advancement except to the extent required by applicable Law. Parent shall, and shall cause the Company and its Subsidiaries to, fulfill and honor any indemnification, expense advancement or exculpation agreements between Parent, Company or any of their respective Subsidiaries and any of their respective directors or officers existing and in effect immediately prior to the Effective Time.

(c) Parent and the Company shall indemnify any Indemnified Person against all reasonable costs and expenses (including reasonable attorneys’ fees and expenses), such amounts to be payable in advance upon request as provided in Section 4.10(a), relating to the enforcement of such Indemnified Person’s rights under this Section 4.10 or under any charter, bylaw or Contract regardless of whether such Indemnified Person is ultimately determined to be entitled to indemnification hereunder or thereunder.

(d) Company will cause to be put in place, and Company shall fully prepay immediately prior to the Effective Time, “tail” insurance policies with a claims reporting or discovery period of at least six (6) years from the Effective Time (the “Tail Period”) from an insurance carrier with the same or better credit rating as Company’s current insurance carrier with respect to directors’ and officers’ liability insurance (“D&O Insurance”) in an amount and scope at least as favorable as Company’s existing policies with respect to matters, acts or omissions existing or occurring at, prior to, or after, the Effective Time; provided, however, that in no event shall the aggregate cost of the D&O Insurance exceed during the Tail Period 300% of the current aggregate annual premium paid by Company, for such purpose; and provided, further, that if the cost of such insurance coverage exceeds such amount, the Company shall obtain a policy with the greatest coverage available for a cost not exceeding such amount.

(e) In the event that Parent, Company or any of their Subsidiaries or any of their respective successors or assignees (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, in each such case, proper provisions shall be made so that the successors and assigns of Parent or the Company, as the case may be, shall assume the obligations set forth in this Section 4.10. The provisions of this Section 4.10 are intended to be for the benefit of, and shall be enforceable by, the Parties and each Person entitled to indemnification or insurance coverage or expense advancement pursuant to this Section 4.10, and his heirs and Representatives. The rights of the Indemnified Persons under this Section 4.10 are in addition to any rights such Indemnified Persons may have under the Organizational Documents of Parent, Company or any of their respective Subsidiaries, or under any applicable Contracts or Law. Parent and the Company shall pay all expenses, including reasonable and documented attorneys’ fees, that may be incurred by any Indemnified Person in enforcing the indemnity and other obligations provided in this Section 4.10.

A-68

Section 4.11 Transaction Litigation. Notwithstanding anything to the contrary contained in this Agreement, in the event any stockholder or shareholder litigation is commenced or, to the knowledge of Company or Parent, as applicable, threatened, that questions the validity or legality of the Transactions or seeks damages or an injunction in connection therewith, including stockholder or shareholder litigation, as applicable (“Transaction Litigation”), Company or Parent, as applicable, shall promptly notify the other Party of such Transaction Litigation and shall keep the other Party reasonably informed with respect to the status thereof. Each Party shall give the other Party a reasonable opportunity to participate in the defense or settlement of any Transaction Litigation (at such Party’s cost) and shall consider in good faith, acting reasonably, the other Party’s advice with respect to such Transaction Litigation; provided that neither Party shall offer or agree to settle any Transaction Litigation without the prior written consent of the other Party.

Section 4.12 Public Announcements. The initial press release with respect to the execution of this Agreement shall be a joint press release to be reasonably agreed upon by the Parties and the investor presentations given to investors on the morning of announcement of the Arrangement shall be reasonably agreed to by each of the Parties. No Party shall, and each will cause its Representatives not to, issue any public announcements or make other public disclosures regarding this Agreement or the Transactions, without the prior written approval of the other Party. Notwithstanding the foregoing, a Party, its Subsidiaries or their Representatives may issue a public announcement or other public disclosures (a) required by applicable Law, (b) required by the rules of any stock exchange upon which such Party’s or its Subsidiary’s capital stock is traded, (c) consistent with the final form of the joint press release announcing the Arrangement and the investor presentations given to investors on the morning of announcement of the Arrangement and (d) subject to Section 4.4, with respect to filings in connection with the Company Circular or Parent Proxy Statement; provided, in the case of clauses (a) and (b), such Party uses reasonable best efforts to afford the other Party a timely opportunity to first review the content of the proposed disclosure and provide reasonable comments thereon; and provided, however, that no provision in this Agreement shall be deemed to restrict in any manner a Party’s ability to communicate with its employees and that neither Party shall be required by any provision of this Agreement to consult with or obtain any approval from any other Party with respect to a public announcement or press release issued in connection with the receipt and existence of a Company Acquisition Proposal or a Parent Acquisition Proposal, as applicable, and matters related thereto or a Company Adverse Recommendation Change or a Parent Adverse Recommendation Change, other than as set forth in Section 4.3.

Section 4.13 Control of Business. Without limiting in any way any Party’s rights or obligations under this Agreement, nothing contained in this Agreement shall give any Party, directly or indirectly, the right to control or direct the other Party and its Subsidiaries’ operations prior to the Effective Time. Prior to the Effective Time, each of the Parties shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

Section 4.14 Pre-Acquisition Reorganization.

(a) Subject to Section 4.14(b), Company agrees that, upon the request of Parent, Company shall, and shall cause its Subsidiaries to, use reasonable best efforts to: (i) implement such reorganizations of their corporate structure, capital structure, business, operations and assets or such other transactions as Parent may request, acting reasonably, including amalgamations, liquidations, reorganizations, continuances (including commencing a continuance process), or share transfers or asset transfers (each a “Pre-Acquisition Reorganization”), (ii) reasonably cooperate with Parent and its advisors to determine the nature of the Pre-Acquisition Reorganizations that might be undertaken and the manner in which they would most effectively be undertaken; and (iii) reasonably cooperate with Parent and its advisors to seek to obtain any material consents, approvals, waivers or similar authorizations, if any, which are reasonably required in connection with the Pre-Acquisition Reorganization, provided that any out-of-pocket costs, fees or expenses (including Taxes) of Company or any of its Subsidiaries associated therewith shall be at Parent’s sole expense. In addition, without limiting Section 4.1, following the entry into this Agreement, Company shall keep Parent apprised of, and consult with Parent in advance of implementing, any reorganizations of the corporate structure of Company and

A-69

its Subsidiaries or any reorganizations, restructurings, transactions or other actions by or among Company and/or any of its Subsidiaries.

(b) Notwithstanding the foregoing, Company will not be obligated to implement any Pre-Acquisition Reorganization under Section 4.14(a) unless such Pre-Acquisition Reorganization:

(i) is not prejudicial to Company or shareholders of Company;

(ii) does not impair the ability of Company or Parent to consummate, and will not materially delay the consummation of, the Arrangement, including to prevent the satisfaction of any conditions set forth in Article 5;

(iii) does not reduce the Consideration or change the form of Consideration to be received by Company shareholders (other than Company shareholders exercising Dissent Rights), as applicable;

(iv) can be effected as close as reasonably practicable to but prior or as of the Closing;

(v) does not require Company or any of its Subsidiaries to take any action that could reasonably be expected to result in any adverse Tax or other adverse consequences to Company shareholders (including any Taxes being imposed on such Persons) that are incrementally greater (by more than a de minimis amount) than the Taxes or other consequences that would be imposed on such Persons in connection with the Transactions in the absence of any action being taken pursuant to Section 4.14(a);

(vi) does not become effective unless Parent has waived or confirmed in writing the satisfaction of all conditions in its favor under Article 5, and has confirmed in writing that it is prepared to promptly and without condition (other than compliance with Section 4.14(a)) proceed to effect the Arrangement;

(vii) does not require Company to obtain the approval of any Company shareholders or the Court; and

(viii) would not result in the breach or violation of any contract to which Company or any of its Subsidiaries is a party (including the Company Credit Facilities or the Company Senior Note Agreements) where the necessary consents, waivers, approvals or similar authorizations have not been or cannot reasonably be obtained prior to the Effective Date.

(c) Parent must provide written notice to Company of any proposed Pre-Acquisition Reorganization at least twenty (20) Business Days prior to the Effective Date (unless providing such notice less than twenty (20) Business Days prior to the Effective Date is not prejudicial to Company, acting reasonably). Upon receipt of such notice, Company and Parent shall work cooperatively and use their reasonable best efforts, to prepare prior to the Effective Time all documentation necessary and do such other acts and things as are necessary to give effect to such Pre-Acquisition Reorganization, including any amendment to this Agreement or the Plan of Arrangement (provided that such amendments do not require Company to obtain approval of the Court or the Company shareholders).

(d) Parent agrees that the implementation of any Pre-Acquisition Reorganization upon request of Parent, by itself, will not be considered in determining whether a representation or warranty or covenant or agreement of Company under this Agreement has been breached (including where any such Pre-Acquisition Reorganization requires the consent of any third party under a Contract).

(e) If the Arrangement is not completed and this Agreement is terminated, Parent will indemnify Company or any of its Subsidiaries undertaking such Pre-Acquisition Reorganization forthwith for all losses and reasonable costs and expenses (including any professional fees and expenses and Taxes) incurred by Company or any of its Subsidiaries in considering or effecting all or any Pre-Acquisition Reorganization, and in connection with reversing or unwinding any Pre-Acquisition Reorganization.

Section 4.15 Dissolution of Enerplus NS. Company agrees that, upon request of Parent, Company shall, and shall cause its Subsidiaries to wind-up and dissolve Enerplus NS as close as practicable prior to the Closing;

A-70

provided that any reasonable and documented out-of-pocket costs, fees or expenses (including Taxes) of Company or any of its Subsidiaries associated therewith shall be at Parent’s sole expense. For greater certainty, such dissolution shall not constitute a Pre-Acquisition Reorganization, provided, however, that Section 4.14(c), Section 4.14(d) and Section 4.14(e) shall apply to such winding up and dissolution, mutatis mutandis.

Section 4.16 Filings. The Parties will cooperate reasonably and in good faith to determine whether the transactions set out in this Agreement and any related transactions are required to be reported to any applicable Taxing Authority pursuant to section 237.3 or 237.4 of the Tax Act (or any provisions of similar effect) and, if so, the Parties shall cooperate to make such reporting in a comprehensive and timely manner, in the form required by applicable Law. The Parties may request reasonable representations and warranties from each other to the extent necessary to establish any factual matters relevant to the determination of whether reporting is required and the content of such reporting.

Section 4.17 Transfer Taxes. The Parties shall cooperate, in good faith, in the filing of any Tax Returns with respect to any transfer, sales, use, stamp, registration or other similar Taxes of any Party or any of its Subsidiaries in respect of the Transactions, and in the minimization, to the extent reasonably permissible under applicable Law, of the amount of any such Taxes.

Section 4.18 Section 16 Matters. Prior to the Effective Time, Parent, Parent Canadian Sub and Company shall take all such steps as may be required to cause any dispositions of equity securities of Company (including derivative securities) or acquisitions of equity securities of Parent (including derivative securities) in connection with this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the U.S. Exchange Act with respect to Company, or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 under the U.S. Exchange Act.

Section 4.19 Registration Status, Stock Exchange Listing and Deregistration.

(a) Until the Closing, Company shall use its reasonable best efforts to (i) maintain its status as a reporting issuer (where such concept exists) not in default (or the equivalent thereof) in each of the provinces and territories of Canada and remain in material compliance with all applicable Canadian Securities Laws in each of the provinces and territories of Canada, (ii) maintain its registration with the SEC under Section 12 of the U.S. Exchange Act and file all reports to be filed under the U.S. Exchange Act and remain in material compliance with all applicable U.S. Securities Laws, and (iii) maintain the listing of the Company Common Shares on the TSX and NYSE and remain in material compliance with the rules of the TSX and NYSE.

(b) Until the Closing, Parent shall use its reasonable best efforts to (i) maintain its registration with the SEC under Section 12 of the U.S. Exchange Act and file all reports required to be filed under the U.S. Exchange Act and remain in material compliance with all applicable U.S. Securities Laws, and (ii) maintain the listing of the shares of Parent Common Stock on NASDAQ and remain in material compliance with the rules of NASDAQ.

(c) Parent shall use reasonable best efforts to take all action necessary to cause the Parent Common Stock to be issued in the Arrangement to be approved for listing on the NASDAQ prior to the Effective Time, subject to official notice of issuance. Prior to the Closing Date, Company shall cooperate with Parent and use reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable Law and rules and policies of each of the TSX and the NYSE to enable the delisting by the Company of the Company Common Shares from each of the TSX and the NYSE and the deregistration of the Company Common Shares under the U.S. Exchange Act promptly after the Effective Time, and in any event no more than ten (10) days after the Effective Time. If the Company is required to file any quarterly or annual report pursuant to the U.S. Exchange Act by a filing deadline that is imposed by the U.S. Exchange Act and which falls on a date within the fifteen (15) days following the Closing Date, the Parties shall reasonably cooperate prior to the Closing Date in preparing any such annual or quarterly report

A-71

reasonably likely to be required to be filed during such period. From and after entry into this Agreement until the earlier of the Closing or the termination of this Agreement, Parent shall promptly notify Company of any material communications or correspondence received by Parent from the NASDAQ with respect to the listing of Parent Common Stock to be issued in the Arrangement or other securities of Parent, compliance with the rules and regulations of the NASDAQ, and any potential suspension or delisting action contemplated or threatened by the NASDAQ.

Section 4.20 Tax Matters.

(a) Company and its Subsidiaries will not without the express written consent of Parent make any “investments” (as defined for purposes of section 212.3 of the Tax Act) in any corporation that is a “foreign affiliate” (as defined in the Tax Act) of Company and/or any of its Subsidiaries (including, for greater certainty, an indirect investment described in paragraph 212.3(10)(f) of the Tax Act), other than (i) in the ordinary course of business, or (ii) by way of a loan that can qualify as a “pertinent loan or indebtedness” (as defined in section 212.3(11) of the Tax Act) and that is evidenced by a promissory note issued by such foreign affiliate.

(b) It is the intent of the Parties that the exchange of Company Common Shares for the Consideration pursuant to this Agreement and the Plan of Arrangement be treated as a taxable transaction for U.S. federal (and applicable state and local) income Tax purposes. The Parties shall (and shall cause their respective Affiliates to) file all applicable Tax Returns on a basis consistent with such intended tax treatment, and take no Tax position inconsistent therewith, except, in each case, as otherwise required by a “determination” within the meaning of Section 1313(a) of the Code (or similar applicable provision).

Section 4.21 Obligations of Parent Canadian Sub and Parent. Parent shall take all action necessary to cause Parent Canadian Sub to perform its obligations under this Agreement and to consummate the transactions contemplated hereby, including the Arrangement, upon the terms and subject to the conditions set forth in this Agreement. Parent unconditionally and irrevocably guarantees the performance by Parent Canadian Sub of all of Parent Canadian Sub’s covenants, agreements and obligations under this Agreement, the Plan of Arrangement and the Transactions, including the Arrangement, and Parent hereby agrees that Company will not be required to first proceed against Parent Canadian Sub before exercising any of it its rights against Parent.

(a) Company and its Subsidiaries shall deliver to Parent at least two (2) Business Days prior to the Closing Date a duly executed payoff letter in form reasonably satisfactory to Parent, setting forth the total amounts payable pursuant to the Company Credit Facilities to fully satisfy all principal, interest, fees, costs, and expenses owed to each holder of Indebtedness under each Company Credit Facility (including to fully cash collateralize all outstanding letters of credit and bankers’ acceptances under the Company Credit Facilities) as of the anticipated Closing Date (and the daily accrual thereafter), together with appropriate wire instructions, and the agreement from the respective administrative agent or sole lender, as applicable, under the applicable Company Credit Facility that upon payment in full of all such amounts owed to such holder, all Indebtedness under such Company Credit Facility shall be discharged and satisfied in full (other than contingent obligations not then due, obligations which survive the termination of the Company Credit Facilities and obligations in respect of letters of credit, bankers’ acceptances and hedging arrangements with respect to which arrangements will be made to the satisfaction of the applicable issuing banks and hedge counterparties, respectively, and Parent and Company), all loan documents entered into in connection with the Company Credit Facilities shall be terminated with respect to Company and its Subsidiaries that are borrowers or guarantors thereof (or the assets of which secure such Indebtedness, if applicable) and all liens on Company and its Subsidiaries and their respective assets (other than liens securing obligations in respect of letters of credit, bankers’ acceptances and hedging arrangements that may survive pursuant to the terms of such payoff letter) shall be released and terminated, together with any applicable documents necessary to evidence the release and termination of all liens on

A-72

Company and its Subsidiaries and their respective assets securing, and any guarantees by Company and its Subsidiaries in respect of, such Company Credit Facility.

(b) Parent shall make adequate arrangements, and Company shall cooperate with Parent in making such arrangements, such that, in connection with the Closing, all outstanding Indebtedness under the Company Credit Facilities, as described above in Section 4.22(a), shall be repaid in full to the appropriate lenders so as to permit the full repayment and termination of the Company Credit Facilities as contemplated therein immediately prior to or concurrent with the Effective Time.

(c) To the extent the Company Senior Notes remain outstanding at the Effective Time, Parent shall (i) comply in all material respects with all requirements under the Company Senior Note Agreements to make all required “change of control” offers to purchase the Company Senior Notes following the Effective Time or (ii) otherwise redeem or repurchase the entire aggregate amount of the Company Senior Notes, in each case in accordance with the terms of the applicable Company Senior Note Agreement. Company shall reasonably cooperate with Parent in connection with Parent fulfilling its obligations hereunder with respect to the Company Senior Notes and compliance with the Company Senior Note Agreements, including in respect of any offer to redeem or otherwise repurchase the Company Senior Notes.

(d) To the extent the Parent Credit Facility remains in effect, Parent shall use reasonable best efforts to make adequate arrangements, at its sole cost and expense (notwithstanding any provision in this Agreement to the contrary), to obtain all necessary waivers, consents or amendments to the Parent Credit Facility to give effect to the Transactions contemplated by this Agreement and the Plan of Arrangement such that there shall be no default or event of default (however denominated) under the Parent Credit Facility through the Effective Time.

Section 4.23 Derivative Contracts; Hedging Matters.

(a) Company shall use reasonable best efforts to assist Parent, its Subsidiaries and its and their Representatives in obtaining any required consent or in the amendment, assignment or novation of any Derivative Transaction (including any commodity hedging arrangement or related Contract) of Company or any of its Subsidiaries, in each case, on terms that are reasonably requested by Parent and effective at and conditioned upon the Closing. If any termination or similar payment is required in respect of any Derivative Transactions, Parent shall pay all such amounts the due and payable.

(b) Between the date hereof and the Effective Time, (i) Company and its Subsidiaries shall not unwind or otherwise modify existing hedges or enter into any Derivative Transactions, other than in the ordinary course of business and in accordance with Company’s Risk Management Policy (provided that Company has reasonably consulted with Parent in advance of making such modifications or entering into any Derivative Transactions, and has considered any such discussions in good faith), and (ii) subject to applicable Law and limitation upon the advice of Company’s counsel, Company shall notify Parent promptly following any changes to Company’s or any of its Subsidiaries’ hedge positions.

Section 4.24 Dividends. Parent agrees to fix the record date for its first quarter 2024 dividends (the “Parent First Quarter Dividends”) as March 5, 2024 (the “Parent First Quarter Dividends Record Date”). Company has advised that the Company Board has declared Company’s first quarter 2024 dividend (the “Company First Quarter Dividend”) in the amount of $0.065 per Company Common Share with a record date of March 4, 2024 (the “Company First Quarter Dividend Record Date”). For all quarterly dividends declared by Parent and Company following the Parent First Quarter Dividend and the Company First Quarter Dividend and until the Effective Time, each of Parent and Company shall coordinate with each other regarding the declaration and payment of dividends in respect of shares of Parent Common Stock and Company Common Shares and the record and payment dates relating thereto, in order to effect the matters contemplated by Section 1.5(b), Section 4.2(b)(i)(A) and this Section 4.24, including that Company shall amend its record dates for quarterly dividends on the Company Common Shares to match the corresponding record dates set by Parent for quarterly

A-73

dividends on the shares of Parent Common Stock, such that neither Parent stockholders nor Company shareholders receive more than one, or no, regular quarterly dividend payments in respect of their share of Parent Common Stock or Company Common Shares, as applicable, in a fiscal quarter, unless the Parties mutually agree that no dividend shall be paid by either Party with respect to a given quarter.

Section 4.25 Parent Cash Available. Parent shall ensure that at Closing it will have available funds (whether pursuant to the Parent Credit Facility, cash on hand or otherwise) to: (a) satisfy the payment of the Cash Consideration payable in accordance with the terms of the Plan of Arrangement, (b) make, within the time periods contemplated herein, the payment of any amount that may become payable by it under Article 6; (c) repay all Indebtedness outstanding under the Company Credit Facilities at or immediately prior to the Effective Time as contemplated in Section 4.22, (d) make and pay all amounts that may become payable under the required “change of control” offers to acquire the Company Senior Notes in accordance with the Company Senior Note Agreements, and (e) make any termination payments in respect of any Derivative Transactions as required in Section 4.23, in each case having regard to Parent’s other liabilities and obligations, and shall take all such actions as may be necessary to ensure that it maintains such availability to ensure that it is able to pay any such amount if and when required.

Section 7.5 Entire Agreement; No Third Party Beneficiaries.

(a) This Agreement, the Company Disclosure Letter, the Parent Disclosure Letter and the Confidentiality Agreement constitute the entire agreement, and supersede all prior understandings, agreements or representations, between the Parties with respect to the subject matter hereof; provided, however, the provisions of this Agreement shall supersede any conflicting provisions of the Confidentiality Agreement.

(b) This Agreement, except for the provisions of Section 4.10 [Indemnification and Insurance], and Section 7.13 [No Recourse] shall not confer any rights or remedies upon any Person other than the Parties and their respective successors and permitted assigns. The provisions of Section 4.10 are intended for the irrevocable benefit of the Persons referenced therein, as and to the extent applicable in accordance with their terms, and shall be enforceable by each of such Persons.

Section 7.6 Assignment; Binding Effect. No Party may assign this Agreement or any of its rights, interests or obligations hereunder (whether by operation of Law or otherwise, including a merger or amalgamation) without the prior written approval of the other Party, and any attempted assignment without such prior written approval shall be void and without legal effect. Subject to the preceding sentence, this Agreement shall be binding upon and inure to the benefit of the Parties and their respective permitted successors and permitted assigns.

Section 7.8 Severability. If the term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, then all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner so that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

Each Party further agrees that no other Party or any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 7.14, and each Party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

Any agreement on the part of any Party to any such extension or waiver shall be valid as against such Party only if set forth in a written instrument signed on behalf of such Party.

Following the receipt of the Final Order and in accordance with Section 1.11 of the Arrangement Agreement, prior to the sending of the Articles of Arrangement to the Registrar, Parent shall deposit, or cause to be deposited, in escrow with the Depositary (i) the aggregate Cash Consideration payable to former Company Shareholders pursuant to the Arrangement, and (ii) the aggregate Share Consideration in certificated or DRS Advice form required to be issued to former Company Shareholders pursuant to the Arrangement, which Consideration shall be held by the Depositary as agent and nominee for such former Company Shareholders for delivery to such former Company Shareholders in accordance with the provisions of this Article 5.

5.2 No Fractional Parent Shares; Rounding

In no event shall any holder of Company Common Shares be entitled to fractional Parent Shares. Where the aggregate number of Parent Shares to be issued to a Company Shareholder as Share Consideration pursuant to the Arrangement would result in a fraction of a Parent Share being issuable, such Company Shareholder shall receive the nearest whole number of Parent Shares. For greater certainty, where such fractional interest is greater than or equal to 0.5, the number of Parent Shares to be issued will be rounded up to the nearest whole number, and where such fractional interest is less than 0.5, the number of Parent Shares to be issued will be rounded down to the nearest whole number. In calculating such fractional interests all Company Common Shares and/or Parent Shares (as applicable) registered in the name of or beneficially held by such holder thereof or their nominee shall be aggregated. In any case where the aggregate Cash Consideration payable to a Company Shareholder under the Arrangement would, but for this provision, include a fraction of a cent, the Cash Consideration payable shall be rounded down to the nearest whole cent.

5.3 Delivery of Consideration

(a) Upon return of a properly completed Letter of Transmittal by a registered former Company Shareholder together with the surrender to the Depositary for cancellation of a certificate or DRS Advice evidencing the surrender of such shares, that immediately before the Effective Time represented one or more outstanding Company Common Shares that were transferred to Parent Canadian Sub in exchange for the Consideration in accordance with Sections 3.2(b) and 4.1(c)(ii) hereof, as applicable, together with such additional documents and instruments as the Depositary may reasonably require, the holder of such surrendered Company Common Shares shall be entitled to receive in exchange therefore, and the Depositary shall deliver to such holder following the Effective Time, (i) the Cash Consideration that such holder is entitled to receive pursuant to the Arrangement, and (ii) a certificate or DRS Advice representing that number of Parent Shares that such holder is entitled to receive as Share Consideration pursuant to the Arrangement, less any amounts deducted or withheld therefrom in accordance with Section 5.6.

(b) After the Effective Time and until surrendered for cancellation as contemplated by Section 5.3(a) but subject to Section 5.7, each Company Common Share shall be deemed at all times to represent only the right to receive in exchange therefor the Consideration that the holder is entitled to receive pursuant to the Arrangement and, for greater certainty, no such

A-110

holder will be entitled to receive any interest, dividends, premium or other payment or distribution in connection therewith (other than as contemplated by Section 5.5).

5.4 Lost Certificates

If any certificate, that immediately prior to the Effective Time represented one or more outstanding Company Common Shares that were transferred to Parent Canadian Sub in exchange for the Consideration in accordance with Section 3.2, shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the holder claiming such certificate to be lost, stolen or destroyed, the Depositary shall deliver in exchange for such lost, stolen or destroyed certificate, the Consideration that such holder is entitled to receive pursuant to the Arrangement. When authorizing such delivery of Consideration that such holder is entitled to receive in exchange for such lost, stolen or destroyed certificate, the holder to whom such Consideration is to be delivered shall, as a condition precedent to the delivery of such Consideration, give a bond satisfactory to Parent and the Depositary in such amount as Parent and the Depositary may direct, or otherwise indemnify Parent and the Depositary in a manner satisfactory to Parent and the Depositary, against any claim that may be made against Parent or the Depositary with respect to the certificate alleged to have been lost, stolen or destroyed.

5.5 Distributions with Respect to Unsurrendered Company Common Shares

No dividend or other distribution declared or made after the Effective Time with respect to Parent Shares with a record date after the Effective Time shall be delivered to any Company Shareholder unless and until the holder shall have complied with the provisions of Section 5.3 or Section 5.4 hereof. All such dividends shall be paid or delivered to the Depositary to be held in trust for the former holder of such Company Common Shares and, subject to applicable Law, at the time of compliance with the provisions of Section 5.3 or Section 5.4 hereof, there shall, in addition to the delivery of Consideration to which such holder is thereby entitled, be delivered to such holder, without interest, the amount of the dividend or other distribution with a record date after the Effective Time theretofore paid with respect to such Parent Shares, net of any amount deducted or withheld therefrom in accordance with Section 5.6 hereof.

5.6 Withholding Rights

Parent, Parent Canadian Sub, Company and the Depositary and their respective affiliates and agents shall be entitled to deduct and withhold from all distributions or payments otherwise payable to any former Company Shareholder, former holder of Company Compensatory Awards or other person (an “Affected Person”) such amounts as any of them is required to deduct and withhold with respect to such payment under the Tax Act, the Code or any provision of any applicable federal, provincial, state, local or foreign Tax Law or treaty, in each case, as amended (a “Withholding Obligation”). To the extent that amounts are so deducted and withheld, such deducted and withheld amounts shall be treated for all purposes hereof as having been paid or delivered to the Affected Person in respect of which such deduction and withholding was made, provided that such deducted and withheld amounts are actually and reasonably timely remitted to the appropriate Taxing Authority. Parent, Parent Canadian Sub, Company and the Depositary and their respective affiliates and agents shall cooperate in good faith with one another and use their respective commercially reasonable efforts to obtain, upon request, a permitted reduction of or relief from any Withholding Obligation. Parent, Parent Canadian Sub, Company, the Depositary and their respective affiliates and agents shall also have the right to:

(a) withhold and sell, on their own account or through a broker (the “Broker”), and on behalf of any Affected Person; or

(b) require the Affected Person to irrevocably direct the sale through a Broker and irrevocably direct the Broker to pay the proceeds of such sale to Company, the Depositary, Parent Canadian Sub or Parent as appropriate (and, in the absence of such irrevocable direction, the Affected Person shall be deemed to have provided such irrevocable direction);

A-111

such number of Parent Shares issued or issuable to such Affected Person pursuant to the Arrangement Agreement as is necessary to produce sale proceeds (after deducting commissions payable to the Broker and other reasonable costs and expenses) sufficient to fund any Withholding Obligation. Any such sale of Parent Shares shall be effected in good faith at prevailing market prices employing commercially reasonable practices on a public market and as soon as practicable following the Effective Date. None of Parent, Parent Canadian Sub, Company, the Depositary, the Broker or their respective affiliates and agents will be liable for any loss arising out of any sale of such Parent Shares if such sale is made in accordance with this Section 5.6.

5.7 Outstanding Certificates and Cheques

To the extent that a former Company Shareholder shall not have complied with the provisions of Section 5.3 or Section 5.4 hereof on or before the day prior to the third anniversary of the Effective Date, such holder and all certificates or DRS Advice representing such Company Common Shares shall cease to have or represent any right or claim of any kind or nature against Parent, Parent Canadian Sub or Company to the Consideration. The Consideration to which such former Company Shareholder was entitled (together with any distributions paid in trust to the Depositary pursuant to Section 5.5), shall be paid or delivered by the Depositary to or as directed by Parent and certificates representing Parent Shares forming the Share Consideration shall be cancelled by Parent. Any payment made by way of cheque by the Depositary pursuant to this Plan of Arrangement that has not been deposited or has been returned to the Depositary or that otherwise remains unclaimed, in each case, on or after the third anniversary of the Effective Date, and any right or claim to payment hereunder that remains outstanding on the third anniversary of the Effective Date shall cease to represent a right or claim of any kind or nature and the right of the holder to receive the applicable consideration pursuant to this Plan of Arrangement shall terminate and be deemed to be surrendered and forfeited to Parent or Parent Canadian Sub, as applicable, for no consideration.

5.8 Paramountcy

From and after the Effective Time: (i) this Plan of Arrangement shall take precedence and priority over any and all Company Common Shares issued and outstanding immediately prior to the Effective Time; (ii) the rights and obligations of the registered holders of Company Common Shares, and Company, Parent, Parent Canadian Sub, the Depositary and any transfer agent or other depositary in relation thereto, shall be solely as provided for in this Plan of Arrangement; and (iii) all actions, causes of action, claims or proceedings (actual or contingent and whether or not previously asserted) based on or in any way relating to any Company Common Shares; shall be deemed to have been settled, compromised, released and determined without liability except as set forth herein.

ARTICLE 6

Opinion of Citigroup Global Markets Inc.

February 21, 2024

The Board of Directors

Chord Energy Corporation

1001 Fannin Street, Suite 1500

Houston, Texas 77002

The Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to Chord Energy Corporation (“Chord”) of the Consideration (defined below) to be paid by Chord pursuant to the terms and subject to the conditions set forth in an Arrangement Agreement (the “Agreement”) proposed to be entered into among Chord, Spark Acquisition ULC, a wholly owned subsidiary of Chord (“Merger Sub”), and Enerplus Corporation (“Enerplus”). As more fully described in the Agreement, Merger Sub will acquire the outstanding common shares in the capital of Enerplus (“Enerplus Common Shares”) in a business combination by way of a plan of arrangement under the Business Corporations Act (Alberta) (the “Arrangement”) for per share consideration consisting of (i) 0.10125 of a share of the common stock, par value $0.01 per share, of Chord (“Chord Common Stock” and, such fraction of a share of Chord Common Stock, the “Stock Consideration”) and (ii) $1.84 in cash (such cash amount, the “Cash Consideration” and, together with the Stock Consideration, the “Consideration”), subject to certain adjustments (as to which adjustments we express no opinion) as set forth in the Agreement. The terms and conditions of the Arrangement are more fully set forth in the Agreement.

In arriving at our opinion, we reviewed a draft, dated February 21, 2024, of the Agreement and held discussions with certain senior officers, directors and other representatives of Chord and certain senior officers and other representatives of Enerplus concerning the businesses, operations and prospects of Chord and Enerplus. We reviewed certain publicly available and other business and financial information relating to Chord and Enerplus provided to or discussed with us by the managements of Chord and Enerplus, including certain financial forecasts and other information and data relating to Chord and Enerplus, and future commodity price estimates and assumptions, prepared by the management of Chord. We also reviewed certain information and data provided to or discussed with us by the management of Chord relating to potential strategic implications and financial and operational benefits (including the amount, timing and achievability thereof) anticipated by such management to result from the Arrangement. We reviewed the financial terms of the Arrangement as set forth in the Agreement in relation to, among other things: current and historical market prices of Chord Common Stock and Enerplus Common Shares; the financial condition and certain historical and projected financial and operating data of Chord and Enerplus; and the capitalization of Chord and Enerplus. We also reviewed certain financial, stock market and other publicly available information relating to the businesses of certain other companies whose operations we considered relevant in evaluating those of Chord and Enerplus and we further reviewed, to the extent publicly available, financial terms of certain other transactions which we considered relevant in evaluating the Arrangement. We further reviewed certain potential pro forma financial effects of the Arrangement utilizing the financial forecasts and other information and data and potential strategic implications and financial and operational benefits referred to above. In addition to the foregoing, we conducted such other analyses and examinations and considered such other information and financial, economic and market criteria as we deemed appropriate in arriving at our opinion. The issuance of our opinion has been authorized by our fairness opinion committee. 

In rendering our opinion, we have assumed and relied, without independent verification, upon the accuracy and completeness of all financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with us and upon the assurances of the managements and other representatives of Chord and Enerplus that they are not aware of any relevant information that has been omitted or that remains undisclosed to us. With respect to the financial forecasts and other information and data, including future commodity price estimates and assumptions, that we have been directed to utilize in our analyses, we have been advised by the management of Chord and we have assumed, with your consent, that they have been reasonably

prepared on bases reflecting the best currently available estimates and judgments of the management of Chord as to, and are a reasonable basis upon which to evaluate, the future financial performance of Chord and Enerplus, the potential strategic implications and financial and operational benefits (including the amount, timing and achievability thereof) anticipated by such management to result from, and other potential pro forma financial effects of, the Arrangement and the other matters covered thereby. We express no view or opinion as to any financial forecasts and other information or data (or underlying assumptions on which they are based) provided to or otherwise reviewed by or discussed with us and we have assumed, with your consent, that the financial results, including with respect to the potential strategic implications and financial and operational benefits anticipated to result from the Arrangement, reflected in such financial forecasts and other information and data will be realized in the amounts and at the times projected.

We have relied, at your direction, upon the assessments of the managements of Chord and Enerplus, as the case may be, as to, among other things, (i) the oil, natural gas and natural gas liquids reserves, reservoir characteristics, undeveloped well inventory, drilling and well development, gathering and transportation and other exploration, development and production activities, as applicable, of Chord and Enerplus, including related costs and expenditures and capital funding requirements, (ii) the potential impact on Chord and Enerplus of macroeconomic, geopolitical, market, competitive, seasonal and other conditions, trends and developments in and prospects for, and governmental, regulatory and legislative matters relating to or otherwise affecting, the oil, natural gas and natural gas liquids industry, including with respect to the geographic regions and basins in which Chord and Enerplus operate, environmental regulations and commodity pricing and supply and demand for oil, natural gas and natural gas liquids, which are subject to significant volatility and which, if different than as assumed, could have a material impact on our analyses or opinion, (iii) existing and future agreements and other arrangements involving, and the ability to attract, retain and/or replace, key employees, customers, service providers, derivatives counterparties and other commercial relationships of Chord and Enerplus, and (iv) the ability of Chord to integrate the operations of Chord and Enerplus and to realize the potential strategic implications and financial and operational benefits as contemplated and as to tax matters relating to Chord and Enerplus both on a standalone and pro forma basis. We have assumed, with your consent, that there will be no developments with respect to any such matters, any pre-closing restructurings or entity dissolutions involving Enerplus or adjustments to the Consideration that would have an adverse effect on Chord, Enerplus or the Arrangement (including the contemplated benefits thereof) or that otherwise would be meaningful in any respect to our analyses or opinion.

We have not made or, except for certain reserve reports relating to Chord and Enerplus, been provided with an independent evaluation or appraisal of the assets or liabilities (contingent, accrued, derivative, off-balance sheet or otherwise) of Chord, Enerplus or any other entity nor have we made any physical inspection of the properties or assets of Chord, Enerplus or any other entity. We express no view or opinion as to reserve quantities, or the exploration, development or production (including, without limitation, as to the feasibility or timing thereof and associated expenditures), of any properties of Chord, Enerplus or any other entity. We have not evaluated the solvency or fair value of Chord, Enerplus or any other entity under any state, federal, provincial or other laws relating to bankruptcy, insolvency or similar matters. We also express no view or opinion as to any actual or potential litigation, claims or governmental, regulatory or other proceedings, enforcement actions, consent decrees or other orders, audits or investigations or the potential impact thereof on Chord, Enerplus or any other entity or the Arrangement.

We have assumed, with your consent, that the Arrangement will be consummated in accordance with its terms and in compliance with all applicable laws, documents and other requirements, without waiver, modification or

amendment of any material term, condition or agreement, and that, in the course of obtaining the necessary governmental, regulatory or third party approvals, consents, releases, waivers and agreements for the Arrangement or otherwise, no delay, limitation, restriction, condition or other action, including any divestiture or other requirements, amendments or modifications, will be imposed or occur that would have an adverse effect on Chord, Enerplus or the Arrangement (including the contemplated benefits thereof) or that otherwise would be meaningful in any respect to our analyses or opinion. Representatives of Chord have advised us, and we also have assumed, that the final terms of the Agreement will not vary materially from those set forth in the draft reviewed by us. Our opinion, as set forth herein, relates to the relative values of Chord and Enerplus (taking into account the Cash Consideration). We are not expressing any view or opinion as to the actual value of Chord Common Stock when issued in connection with the Arrangement or the prices at which Chord Common Stock, Enerplus Common Shares or any other securities Chord or Enerplus may trade or otherwise be transferable at any time, including following the announcement or consummation of the Arrangement. We also are not expressing any view or opinion with respect to accounting, tax, regulatory, legal or similar matters, including, without limitation, as to tax or other consequences of the Arrangement or otherwise or changes in, or the impact of, accounting standards or tax and other laws, regulations and governmental and legislative policies affecting Chord, Enerplus or the Arrangement (including the contemplated benefits thereof), and we have relied, with your consent, upon the assessments of representatives of Chord as to such matters.

Our opinion addresses only the fairness, from a financial point of view and as of the date hereof, to Chord of the Consideration (to the extent expressly specified herein), and does not address any other terms, aspects or implications of the Arrangement, including, without limitation, the form or structure of the Arrangement, any regular or additional dividends contemplated by the Agreement, adjustments to the Consideration, pre-closing restructurings or entity dissolutions or any other terms, aspects or implications of any agreement, arrangement or understanding to be entered into in connection with or contemplated by the Arrangement or otherwise. We express no view as to, and our opinion does not address, the underlying business decision of Chord to effect or enter into the Arrangement, the relative merits of the Arrangement as compared to any alternative business strategies that might exist for Chord or the effect of any other transaction that Chord might engage in or consider. We also express no view as to, and our opinion does not address, the fairness (financial or otherwise) of the amount or nature or any other aspect of any compensation or other consideration to any officers, directors or employees of any parties to the Arrangement, or any class of such persons, relative to the Consideration or otherwise. Our opinion is necessarily based upon information available, and financial, stock market and other conditions and circumstances existing and disclosed, to us as of the date hereof. Although subsequent developments may affect our opinion, we have no obligation to update, revise or reaffirm our opinion. As you are aware, the industries in which Chord and Enerplus operate (including commodity prices related to such industries) and the securities of Chord and Enerplus have experienced and may continue to experience volatility and disruptions, and we express no view or opinion as to any potential effects of such volatility or disruptions on Chord, Enerplus or the Arrangement (including the contemplated benefits thereof).

Citigroup Global Markets Inc. has acted as financial advisor to Chord in connection with the proposed Arrangement and will receive a fee for such services, of which a portion is payable upon the delivery of this opinion and the principal portion is contingent upon consummation of the Arrangement. We also may be entitled to an additional fee for such services payable at the discretion of Chord. In addition, Chord has agreed to reimburse our expenses and to indemnify us against certain liabilities arising from our engagement. 

As you are aware, we and our affiliates in the past have provided, currently are providing and in the future may provide investment banking, commercial banking and other similar financial services to Chord and/or certain of

its affiliates unrelated to the proposed Arrangement, for which services we and our affiliates have received and expect to receive compensation, including, during the past approximately two years, having acted or acting as a lender under a credit facility of an affiliate of Chord. Although we and our affiliates have not provided investment banking, commercial banking or other similar financial services during the past two years to Enerplus for which services we or our affiliates have received or expect to receive compensation, we and our affiliates in the future may provide such services to Enerplus and/or its affiliates for which services we and our affiliates would expect to receive compensation. In the ordinary course of business, we and our affiliates may actively trade or hold the securities or financial instruments (including loans and other obligations) of Chord, Enerplus and their respective affiliates for our own account or for the account of our customers and, accordingly, may at any time hold a long or short position or otherwise effect transactions in such securities or financial instruments. In addition, we and our affiliates (including Citigroup Inc. and its affiliates) may maintain relationships with Chord, Enerplus and their respective affiliates.

Our advisory services and the opinion expressed herein are provided for the information of the Board of Directors of Chord (in its capacity as such) in its evaluation of the proposed Arrangement. Our opinion is not intended to be and does not constitute a recommendation as to how the Board of Directors of Chord or any securityholder should vote or act on any matters relating to the proposed Arrangement or otherwise.

Based upon and subject to the foregoing, our experience as investment bankers, our work as described above and other factors we deemed relevant, we are of the opinion that, as of the date hereof, the Consideration to be paid by Chord pursuant to the Agreement is fair, from a financial point of view, to Chord.

Very truly yours,
