On February 1, 2016, Dominion held a conference call with analysts and investors during which information was provided regarding the proposed Merger (as defined below). Certain materials presented on the conference call are attached as Exhibit 99.3 hereto and are incorporated herein by reference.

On February 1, 2016, Thomas F. Farrell II, President, Chairman and CEO of Dominion, sent an email and video to Questar employees. The email is attached as Exhibit 99.4 hereto and the transcript of the video is attached as Exhibit 99.5 hereto, both of which are incorporated herein by reference.

Item 8.01 Other Events

On January 31, 2016, Dominion entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among Dominion, Diamond Beehive Corp., a Utah corporation and wholly-owned subsidiary of Dominion (“Merger Sub”), and Questar. The following description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which is attached as Exhibit 99.1 to this report and is incorporated by reference herein.

The Merger Agreement provides for Merger Sub to merge with and into Questar (the “Merger”), with Questar continuing as the surviving corporation and a wholly-owned subsidiary of Dominion. At the effective time of the Merger, each issued and outstanding share of common stock of Questar will be cancelled and converted into the right to receive $25.00 per share in cash, without interest.

The Merger Agreement contains customary representations, warranties, covenants and termination provisions. Consummation of the Merger is subject to the satisfaction or waiver of certain specified closing conditions, including (i) approval of the Merger and Merger Agreement by Questar’s shareholders, (ii) compliance with applicable state regulatory filing and approval requirements and (iii) other customary closing conditions. The Merger Agreement provides that as soon as practicable after the effective time of the Merger, Dominion intends that its board of directors will take all necessary action to appoint a mutually agreeable current member of the board of directors of Questar to serve on Dominion’s board of directors.

In connection with the Merger Agreement, Dominion entered into a Commitment Letter with Mizuho Bank, Ltd. (“Mizuho”) and Royal Bank of Canada (“RBC”) pursuant to which Mizuho and RBC have committed to provide debt financing consisting of a $3.9 billion senior unsecured bridge and term loan facility (which will be decreased at the time of certain offerings or transactions that occur prior to the consummation of the Merger). The obligations of Mizuho and RBC to provide this debt financing are subject to a number of customary conditions, including the execution and delivery of certain definitive documentation.

The representations and warranties contained in the Merger Agreement were made only for the purposes of the Merger Agreement as of the specific dates therein, and were solely for the benefit of the parties to the Merger Agreement. The representations and warranties contained in the Merger Agreement may be subject to limitations agreed upon by the parties to the Merger Agreement and are qualified by information in confidential disclosure schedules provided in connection with the signing of the Merger Agreement. These confidential disclosure schedules contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Merger Agreement. Moreover, certain representations and warranties in the Merger Agreement may be subject to a standard of materiality provided for in the Merger Agreement and have been used for the purpose of allocating risk among the parties, rather than establishing matters of fact. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Dominion’s public disclosures.

Forward Looking Statements

This report includes certain forward-looking information that is subject to various risks and uncertainties. Words such as “expect,” “target,” “would,” “will,” “anticipate,” “believe,” “estimate,” “intend,” “may,” “plan,” “predict,” “project,” “should” and similar terms and phrases are used to identify forward-looking statements. There are a number of factors that could cause actual results to differ from those in the forward-looking statements. For example, (i) Questar may not be able to obtain the required shareholder approval of the Merger, (ii) the parties may be unable to obtain necessary regulatory approvals for the Merger or required regulatory approvals may delay the Merger or cause the parties to abandon the Merger, (iii) conditions to the closing of the Merger or the committed debt financing may not be satisfied or (iv) an unsolicited offer for the assets or capital stock of Questar may interfere with the Merger. Accordingly, forward-looking statements are not guarantees or assurances of future outcomes and actual results could differ materially from those indicated by the forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and the company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which it is made.

ARTICLE II

EFFECT OF THE MERGER ON CAPITAL STOCK

Section 2.1 Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Parent or Merger Sub or any holder of any shares of common stock, without par value, of the Company (“Company Common Stock”) or any shares of capital stock of Merger Sub:

(a) Capital Stock of Merger Sub. Each issued and outstanding share of capital stock of Merger Sub shall be converted into and become one validly issued, fully paid and non-assessable share of common stock, no par value per share, of the Surviving Corporation.

(b) Cancellation of Parent-Owned Stock. Any shares of Company Common Stock that are owned by Parent or Merger Sub or any of their respective Subsidiaries, in each case immediately prior to the Effective Time, shall be automatically canceled and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(c) Conversion of Company Common Stock. Each issued and outstanding share of Company Common Stock (other than Dissenting Shareholder Shares and shares to be canceled in accordance with Section 2.1(b)) shall thereupon be converted automatically into and shall thereafter represent solely the right to receive an amount in cash equal to $25.00 without interest (the “Merger Consideration”). As of the Effective Time, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and the holders immediately prior to the Effective Time of shares of Company Common Stock not represented by certificates (“Book-Entry Shares”) and the holders of certificates that immediately prior to the Effective Time represented any such shares of Company Common Stock (each, a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration to be paid in consideration therefor upon surrender of such Book-Entry Share or Certificate in accordance with Section 2.2(b) (subject to any applicable withholding Tax).

4

(d) Dissenters’ Rights. Notwithstanding anything in this Agreement to the contrary, shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time which are held by a shareholder who did not vote in favor of the Merger (or consent thereto in writing) and who is entitled to demand and properly demands payment of the fair value of such shares pursuant to, and complies in all respects with, the provisions of Part 13 of the URBCA (the “Dissenting Shareholder Shares”, and each shareholder holding Dissenting Shareholder Shares, a “Dissenting Shareholder”) shall not be converted into or be exchangeable for the right to receive the Merger Consideration, but instead such Dissenting Shareholder shall be entitled to receive such consideration as may be determined to be due to such Dissenting Shareholder pursuant to Section 1302 of the URBCA (and as of the Effective Time, such Dissenting Shareholder Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and such Dissenting Shareholder shall cease to have any rights with respect thereto, except the rights set forth in Part 13 of the URBCA), unless and until such Dissenting Shareholder shall have failed to perfect or shall have effectively withdrawn or lost rights to payment under Part 13 of the URBCA. If any Dissenting Shareholder shall have failed to perfect or shall have effectively withdrawn or lost such right, such Dissenting Shareholder’s shares of Company Common Stock shall thereupon be treated as if they had been converted into and become exchangeable for the right to receive, as of the Effective Time, the Merger Consideration for each such share of Company Common Stock, in accordance with Section 2.1(a), subject to any applicable withholding Tax. The Company shall give Parent (i) prompt notice of any written demands for payment of the fair value of any shares of Company Common Stock, attempted withdrawals of such demands and any other instruments served pursuant to the URBCA and received by the Company relating to shareholders’ dissenters’ rights under Part 13 of the URBCA and (ii) the opportunity to participate in and direct all negotiations and proceedings with respect to demands for payment of fair value under the URBCA. The Company shall not, except with the prior written consent of Parent (not to be unreasonably withheld, conditioned or delayed), make any payment with respect to any such demands for payment or settle or offer to settle any such demands for payment.

Section 2.2 Exchange of Certificates.

(a) Paying Agent; Investment by Paying Agent of Funds. Prior to the Effective Time, Parent shall designate a bank or trust company reasonably acceptable to the Company (the “Paying Agent”) for the purpose of exchanging shares of Company Common Stock for the Merger Consideration and enter into an agreement reasonably acceptable to the Company with the Paying Agent relating to the services to be performed by the Paying Agent. Parent shall irrevocably deposit, or cause to be deposited, the aggregate Merger Consideration with respect to all shares of Company Common Stock (other than Dissenting Shareholder Shares and shares to be canceled in accordance with Section 2.1(b)) with the Paying Agent at or prior to the Effective Time. The aggregate Merger Consideration deposited with the Paying Agent shall, pending its disbursement to holders of shares of Company Common Stock and as reasonably directed by Parent, be invested by the Paying Agent in (i) short-term commercial paper obligations of issuers organized under the Laws of a state of the United States of America, rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Ratings Service, respectively, or in certificates of deposit, bank repurchase agreements or bankers’ acceptances of commercial banks with capital exceeding $10,000,000,000, or in mutual funds investing in such assets or (ii) short-term obligations for which the full faith and credit of the United States of

5

America is pledged to provide for the payment of principal and interest. Any interest and other income from such investments shall become part of the funds held by the Paying Agent for purposes of paying the Merger Consideration. No investment or investment losses resulting from such investment by the Paying Agent of the aggregate Merger Consideration shall relieve Parent, the Surviving Corporation or the Paying Agent from making the payments required by this Article II, and Parent shall promptly replace any funds deposited with the Paying Agent lost through any investment made pursuant to this Section 2.2(a). No investment by the Paying Agent of the aggregate Merger Consideration shall have maturities that could prevent or delay payments to be made pursuant to this Agreement. Following the Effective Time, Parent agrees to make available to the Paying Agent, from time to time as needed, additional cash to pay the Merger Consideration as contemplated by this Article II without interest.

(b) Payment Procedures. As promptly as practicable after the Effective Time (but in no event more than two (2) Business Days thereafter), the Surviving Corporation shall cause the Paying Agent to mail to each holder of record of shares of Company Common Stock (i) a letter of transmittal (which, in the case of shares of Company Common Stock represented by Certificates, shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent, and shall be in such form and have such other provisions as Parent and the Company may reasonably agree and shall be prepared prior to Closing) and (ii) instructions for use in effecting the surrender of the Certificates or Book-Entry Shares in exchange for payment of the Merger Consideration. Upon surrender of Certificates for cancellation to the Paying Agent or, in the case of Book-Entry Shares, receipt of an “agent’s message” by the Paying Agent (or such other evidence, if any, of transfer as the Paying Agent may reasonably request), together with such letter of transmittal, duly completed and validly executed in accordance with the instructions (and such other customary documents as may reasonably be required by the Paying Agent), the holder of such Certificates or Book-Entry Shares shall be entitled to receive in exchange therefor, subject to any required withholding Taxes, the Merger Consideration, for each share of Company Common Stock surrendered, and any Certificates surrendered shall forthwith be canceled. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate or Book-Entry Share in exchange therefor is registered, it shall be a condition of payment that (A) the Person requesting such exchange present proper evidence of transfer and (B) the Person requesting such payment shall have paid any transfer and other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of such Certificate or Book-Entry Share surrendered or shall have established to the reasonable satisfaction of the Surviving Corporation that such Tax either has been paid or is not applicable. Until surrendered as contemplated by this Section 2.2, each Certificate and Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration as contemplated by this Article II.

(c) Transfer Books; No Further Ownership Rights in Company Common Stock. The Merger Consideration paid in respect of shares of Company Common Stock upon the surrender for exchange in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock, and at the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock that were outstanding immediately prior

to the Effective Time. From and after the Effective Time, the holders of Certificates or Book-Entry Shares that evidenced ownership of shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares of Company Common Stock other than the right to receive the Merger Consideration, except as otherwise provided for herein or by applicable Law.

(e) Termination of Fund. At any time following the first (1st) anniversary of the Closing Date, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) that had been made available to the Paying Agent and which have not been disbursed in accordance with this Article II, and thereafter Persons entitled to receive payment pursuant to this Article II shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) as general creditors thereof with respect to the payment of any Merger Consideration that may be payable upon surrender of any Company Common Stock held by such holders, as determined pursuant to this Agreement, without any interest thereon. Any amounts remaining unclaimed by such holders at such time at which such amounts would otherwise escheat to or become property of any Governmental Authority shall become, to the extent permitted by applicable Law, the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.

(f) No Liability. Notwithstanding any other provision of this Agreement, none of Parent, the Merger Sub, the Surviving Corporation, the Company or the Paying Agent shall be liable to any Person for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

To the extent amounts are so withheld and timely paid over to the appropriate Taxing authority, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made. Parent, the Company, the Surviving Corporation, and the Paying Agent shall cooperate with such holders in all reasonable respects, and in compliance with applicable Law, to minimize the amount of any applicable withholding.

Such obligation shall be payable or distributable in accordance with the terms of the agreement, plan or arrangement relating to such Company Awards (or, if earlier, on the death of the holder thereof) and, prior to the time of distribution, such amounts shall be permitted to be deemed invested in a permitted investment option under the applicable agreement, plan or arrangement.

(f) Accumulated Dividends. Immediately prior to the Effective Time, the Company shall distribute all Accumulated Dividends to the applicable holders of Company RSUs and Company Awards.

(g) Withholding. The Surviving Corporation shall be entitled to deduct and withhold from the amounts otherwise payable pursuant to this Section 2.3 to any holder of Company RSUs, Company Performance Share Awards, Company Restricted Shares, Company Stock Options, Company Awards or Accumulated Dividends such amounts as the Surviving Corporation is required to deduct and withhold with respect to the making of such payment under the Code, or any applicable provision of state, or local Law related to Tax, and the Surviving Corporation shall timely make any required filings and payments to Tax authorities relating to any such deduction or withholding. To the extent that amounts are so deducted and withheld by the Surviving Corporation, such withheld amounts shall be treated for the purposes of this Agreement as having been paid to the holder of Company RSUs, Company Performance Share Awards, Company Restricted Shares, Company Stock Options, Company Awards or Accumulated Dividends in respect of which such deduction and withholding was made by the Surviving Corporation.

(h) Funding. No later than the Effective Time, Parent shall provide, or shall cause to be provided, to the Surviving Corporation all funds necessary to fulfill the obligations under this Section 2.3.

Each Reporting Company’s disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed by such Reporting Company in the reports that it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to such Reporting Company’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications required pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act.

14

complied, as of their respective dates, with all applicable requirements of the applicable Laws, except for Regulatory Filings the failure of which to make or the failure of which to make in compliance with all applicable requirements of the applicable Laws have not had and would not reasonably be expected to have a Company Material Adverse Effect.

(f) Between the date of this Agreement and the Effective Time, the Company shall, and shall cause its Subsidiaries to, use commercially reasonable efforts to ensure that its firm transportation and firm storage contracts are reviewed and renewed at levels that would maintain adequate peak-day gas supplies for customers.

(g) Between the date of this Agreement and the Effective Time, the Company shall, and shall cause its Subsidiaries to, use commercially reasonable efforts to cooperate and coordinate with Parent with respect to the transition matters set forth on Section 5.1(g) of the Company Disclosure Schedule.

Section 5.2 Preparation of the Proxy Statement; Shareholders Meeting.

(a) As promptly as reasonably practicable following the date of this Agreement, but in any event within thirty (30) Business Days, the Company shall prepare and file with the SEC the Proxy Statement, and Parent shall cooperate with the Company with the preparation of the foregoing. The Company, with Parent’s cooperation, shall use commercially reasonable efforts to respond as promptly as reasonably practicable to and resolve all comments received from the SEC or its staff concerning the Proxy Statement. The Company agrees that (i) except with respect to any information supplied in writing to the Company by Parent or Merger Sub for inclusion or incorporation by reference in the Proxy Statement, the Proxy Statement will comply in all material respects with the applicable provisions of the Exchange Act and the rules and regulations thereunder and (ii) none of the information supplied or to be supplied by the Company for inclusion or incorporation by reference in the Proxy Statement will, on the date it is first mailed to shareholders of the Company and at the time of the Company Shareholders Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The Company will cause the Proxy Statement to be mailed to the Company’s shareholders, as promptly as reasonably practicable after the SEC confirms that it has no further comments on the Proxy Statement. No filing of, or amendment or supplement to, or correspondence with the SEC with respect to, the Proxy Statement will be made by the Company without providing Parent a reasonable opportunity to review and comment thereon and with the Company considering in good faith such comments; provided, however, that the foregoing shall not apply with respect to a Takeover Proposal, a Superior Proposal, a Company Adverse Recommendation Change or any matters relating thereto. Each of Parent and Merger Sub shall cooperate with the Company in connection with the preparation and filing of the Proxy Statement, including promptly furnishing to the Company in writing upon request any and all information relating to it as may be required to be set forth in the Proxy Statement under applicable Law. Each of the Parent and Merger Sub agrees that such information supplied by it in writing for inclusion (or incorporation by reference) in the Proxy Statement will not, on the date it is first mailed to shareholders of the Company and at the time of the Company Shareholders Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. If, at any time prior to the Effective Time, any information relating to Parent or Merger Sub or any of their

29

respective Affiliates, officers or directors, should be discovered by Parent or Merger Sub which should be set forth in an amendment or supplement to the Proxy Statement so that the Proxy Statement would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, Parent (or Merger Sub, as the case may be) shall promptly notify the Company so that it may file with the SEC an appropriate amendment or supplement describing such information and, to the extent required by Law, disseminate such amendment or supplement to the shareholders of the Company. If, at any time prior to the Effective Time, any information relating to the Company or any of its respective Affiliates, officers or directors should be discovered by the Company which should be set forth in an amendment or supplement to the Proxy Statement so that the Proxy Statement would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Company shall promptly notify Parent and the Company shall file with the SEC an appropriate amendment or supplement describing such information and, to the extent required by Law, disseminate such amendment or supplement to the shareholders of the Company.

(b) The Company shall, as promptly as reasonably practicable after the date of the mailing of the definitive Proxy Statement to the Company’s shareholders, in accordance with applicable Law, the Company Charter Documents and the NYSE rules, duly give notice of, convene and hold a meeting of its shareholders to consider the approval of this Agreement, the plan of merger and such other matters as may be then reasonably required (including any adjournment or postponement thereof, the “Company Shareholders Meeting”); provided, however, that the Company shall be permitted to delay or postpone convening the Company Shareholders Meeting (i) with the consent of Parent, (ii) for the absence of a quorum, (iii) to allow reasonable additional time for any supplemental or amended disclosure which the Company has determined in good faith (after consultation with outside legal counsel) is necessary under applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by the Company’s shareholders prior to the Company Shareholders Meeting as necessary under applicable Law or (iv) to allow additional solicitation of votes in order to obtain the Company Shareholder Approval. Except if there has been a Company Adverse Recommendation Change in accordance with Section 5.3(d), the Company shall use its reasonable best efforts to solicit and secure the Company Shareholder Approval.

(c) Subject to Section 5.3 and the right of the Company Board to make a Company Adverse Recommendation Change pursuant thereto, unless and until there has been a Company Adverse Recommendation Change in accordance with Section 5.3, the Company shall include the Company Board Recommendation in the preliminary and definitive Proxy Statement. Subject to the Company’s right to terminate this Agreement under Section 7.1(d)(ii), the Company’s obligations under this Section 5.2 shall not be affected by the commencement, public proposal or communication to the Company of a Takeover Proposal, or by the withdrawal or modification by the Company Board of the Company Board Recommendation.

Section 5.3 No Solicitation; Change in Recommendation.

(a) The Company agrees that it shall, and shall cause its Subsidiaries and its and its Subsidiaries’ respective directors, officers and employees to, and shall use its reasonable

30

best efforts to cause its other Representatives to, immediately cease all existing discussions or negotiations with any Person conducted heretofore with respect to any Takeover Proposal. Except as otherwise provided in this Agreement, from the date of this Agreement until the earlier of the Effective Time or the date, if any, on which this Agreement is terminated pursuant to Section 7.1, the Company shall not, and shall cause its Subsidiaries and its and its Subsidiaries’ respective directors, officers and employees not to, and shall use its reasonable best efforts to cause its other Representatives not to, directly or indirectly, (i) solicit, initiate, knowingly encourage or knowingly facilitate any Takeover Proposal or the making or consummation thereof or (ii) enter into, or otherwise participate in any discussions (except to notify such Person of the existence of the provisions of this Section 5.3) or negotiations regarding, or furnish to any Person any non-public material information in connection with, any Takeover Proposal.

(b) Notwithstanding anything to the contrary contained in this Agreement, if the Company or any of its Subsidiaries, or any of its or their respective Representatives receives an unsolicited written Takeover Proposal made after the date of this Agreement and prior to receipt of the Company Shareholder Approval, the Company, the Company Board (or a duly authorized committee thereof) and the Company’s Representatives may engage in negotiations and discussions with, or furnish any information and other access to, any Person making such Takeover Proposal and any of its Representatives or potential sources of financing if the Company Board determines in good faith, after consultation with the Company’s outside legal and financial advisors, that such Takeover Proposal is or could reasonably be expected to lead to a Superior Proposal and that failure to take such actions would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law; provided that prior to engaging in any negotiations or discussions with, or furnishing any non-public information to, any such Person or its Representatives, the Company and the Person making such Takeover Proposal shall have entered into an Acceptable Confidentiality Agreement. The Company will promptly (and in any event within the later of twenty-four (24) hours and 5:00 p.m. Salt Lake City time on the next Business Day) notify Parent in writing of the receipt of such Takeover Proposal and the material terms and conditions of such Takeover Proposal, including the identity of the Person making such Takeover Proposal. The Company will keep Parent promptly informed (and in any event within the later of twenty-four (24) hours and 5:00 p.m. Salt Lake City time on the next Business Day) in all material respects of the status of and material communications relating to such Takeover Proposal (including any change in the price or other material terms thereof). The Company shall not terminate, amend, modify, waive or fail to enforce any provision of any “standstill” or similar obligation of any Person unless the Company Board (or a duly authorized committee thereof) determines in good faith, after consultation with its outside legal counsel, that the failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law.

(c) Except as otherwise provided in this Agreement, neither the Company Board nor any committee thereof shall (i)(A) withdraw, change, qualify, withhold or modify, or publicly propose to withdraw, change, qualify, withhold or modify, in a manner adverse to Parent, the Company Board Recommendation, (B) adopt, approve or recommend, or publicly propose to adopt, approve or recommend, any Takeover Proposal, (C) fail to include the Company Board Recommendation in the Proxy Statement or (D) fail to recommend against any Takeover Proposal subject to Regulation 14D under the Exchange Act in any solicitation or recommendation statement made on Schedule 14D-9 within ten (10) Business Days after Parent

31

so requests reaffirmation in writing (provided, that Parent shall be entitled to make such a written request for reaffirmation only once for each Takeover Proposal and once for each material amendment to such Takeover Proposal) (any action described in this clause (i) being referred to herein as a “Company Adverse Recommendation Change”) or (ii) cause or permit the Company or any of its Affiliates to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, agreement or commitment (other than an Acceptable Confidentiality Agreement) constituting, or that would reasonably be expected to lead to, any Takeover Proposal (a “Company Acquisition Agreement”).

(d) Notwithstanding anything to the contrary in this Agreement, at any time prior to obtaining the Company Shareholder Approval, the Company Board (or a duly authorized committee thereof) may make a Company Adverse Recommendation Change (and, solely with respect to a Superior Proposal, terminate this Agreement pursuant to Section 7.1(d)(ii)), if (i) (A) a Company Intervening Event has occurred or (B) the Company has received a Superior Proposal other than as a result of a breach of this Section 5.3 (other than immaterial breach), in each case, if the Company Board (or a duly authorized committee thereof) determines in good faith, after consultation with its outside legal counsel, that the failure to make a Company Adverse Recommendation Change as a result of the occurrence of such Company Intervening Event or in response to the receipt of such Superior Proposal, as the case may be, would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law and (ii) (A) the Company provides Parent prior written notice of its intent to make any Company Adverse Recommendation Change or terminate this Agreement pursuant to Section 7.1(d)(ii) at least four (4) Business Days prior to taking such action to the effect that, absent any modification to the terms and conditions of this Agreement, the Company Board has resolved to effect a Company Adverse Recommendation Change or to terminate this Agreement pursuant to Section 7.1(d)(ii), which notice shall specify the basis for such Company Adverse Recommendation Change or termination and attaching the most current draft of any Company Acquisition Agreement and any other material documents with respect to, the Superior Proposal (or, if no such draft exists, a summary of the material terms and conditions of such Superior Proposal), if applicable (a “Notice of Recommendation Change”) (it being understood that such Notice of Recommendation Change shall not in itself be deemed a Company Adverse Recommendation Change and that any change in price or material revision or amendment to the terms of a Superior Proposal, if applicable, shall require a new notice to which the provisions of clauses (ii)(A), (B) and (C) of this Section 5.3(d) shall apply mutatis mutandis except that, in the case of such a new notice, all references to four (4) Business Days in this Section 5.3(d) shall be deemed to be two (2) Business Days); (B) during such four (4) Business Day period, if requested by Parent, the Company shall make its Representatives reasonably available to negotiate in good faith with Parent and its Representatives regarding any modifications to the terms and conditions of this Agreement that Parent proposes to make; and (C) at the end of such four (4) Business Day period and taking into account any modifications to the terms of this Agreement proposed by Parent to the Company in a written, binding and irrevocable offer, the Company Board determines in good faith (after consultation with outside legal counsel) that the failure to make such a Company Adverse Recommendation Change would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law, and that, in the case of a Company Adverse Recommendation Change with respect to a Takeover Proposal, such Takeover Proposal still constitutes a Superior Proposal.

32

(e) Nothing contained in this Agreement shall prohibit the Company or the Company Board (or a duly authorized committee thereof) from (i) taking and disclosing to the shareholders of the Company a position contemplated by Rule 14e-2(a) under the Exchange Act or making a statement contemplated by Item 1012(a) of Regulation M-A or Rule 14d-9 under the Exchange Act, (ii) making any disclosure to the shareholders of the Company if the Company Board (or a duly authorized committee thereof) determines in good faith, after consultation with its outside legal counsel, that the failure to make such disclosure would be reasonably likely to be inconsistent with applicable Law, (iii) informing any Person of the existence of the provisions contained in this Section 5.3 or (iv) making any “stop, look and listen” communication to the shareholders of the Company pursuant to Rule 14d-9(f) under the Exchange Act (or any similar communication to the shareholders of the Company). No disclosures under this Section 5.3(e) shall be, in themselves, a breach of Section 5.3 or a basis for Parent to terminate this Agreement pursuant to Article VII.

(f) As used in this Agreement, “Takeover Proposal” shall mean any bona fide inquiry, proposal or offer from any Person (other than Parent, Merger Sub and any of its Affiliates thereof) to purchase or otherwise acquire, directly or indirectly, in a single transaction or series of related transactions, (a) assets of the Company and its Subsidiaries (including securities of Subsidiaries) that account for 15% or more of the Company’s consolidated assets or from which 15% or more of the Company’s revenues or earnings on a consolidated basis are derived or (b) 15% or more of the outstanding Company Common Stock pursuant to a merger, consolidation or other business combination, sale or issuance of shares of capital stock, tender offer, share exchange, recapitalization or similar transaction involving the Company, in each case other than the Merger.

(g) As used in this Agreement, “Superior Proposal” shall mean any unsolicited written Takeover Proposal on terms which the Company Board (or a duly authorized committee thereof) determines in good faith, after consultation with the Company’s outside legal counsel and independent financial advisors, to be more favorable to the holders of Company Common Stock than the Transactions (as may be revised pursuant to Section 5.3(d) of this Agreement), taking into account, to the extent applicable, the legal, financial, regulatory and other aspects of such proposal and this Agreement that the Company Board considers relevant; provided that for purposes of the definition of Superior Proposal, the references to “15%” in the definition of Takeover Proposal shall be deemed to be references to “50%.”

Section 5.4 Reasonable Best Efforts.

(a) Subject to the terms and conditions of this Agreement, each of the Company, Parent and Merger Sub shall use its respective reasonable best efforts to (i) cause the Transactions to be consummated as soon as practicable, (ii) make promptly any required submissions and filings under applicable Antitrust Laws or to Governmental Authorities with respect to the Transactions, (iii) promptly furnish information required in connection with such submissions and filing to such Governmental Authorities or under such Antitrust Laws, (iv) keep the other parties reasonably informed with respect to the status of any such submissions and filings to such Governmental Authorities or under Antitrust Laws and cooperate with each other, including with respect to: (A) the receipt of any non-action, action, clearance, consent, approval or waiver, (B) the expiration of any waiting period, (C) the commencement or proposed or

33

threatened commencement of any investigation, litigation or administrative or judicial action or proceeding under Antitrust Laws or other applicable Laws and (D) the nature and status of any objections raised or proposed or threatened to be raised under Antitrust Laws or other applicable Laws with respect to the Transactions and (v) obtain all actions or non-actions, approvals, consents, waivers, registrations, permits, authorizations and other confirmations from any Person necessary to consummate the Transactions as soon as practicable. For purposes hereof, “Antitrust Laws” means the Sherman Act, the Clayton Act, the HSR Act, the Federal Trade Commission Act, all applicable foreign Antitrust Laws and all other applicable Laws issued by a Governmental Authority that are designed or intended to prohibit, restrict or regulate actions having the purpose or effect of monopolization or restraint of trade or lessening of competition through merger or acquisition.

(b) In furtherance and not in limitation of the foregoing: (i) each party hereto agrees to (A) make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the Transactions as promptly as reasonably practicable following the date of this Agreement (and in any event within ten (10) Business Days after the date hereof (unless the parties otherwise agree)), (B) supply as soon as practicable any additional information and documentary material that may be requested pursuant to the HSR Act and (C) use its reasonable best efforts to take, or cause to be taken, all other actions consistent with this Section 5.4 necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act (including any extensions thereof) as soon as practicable and (ii) each party agrees to (A) make or cause to be made the appropriate filings (including notice filings) as soon as practicable (and in any event within twenty-one (21) Business Days after the date hereof (unless the parties otherwise agree)) with the PSCU, PSCW and PUCI relating to the Merger, (B) supply as soon as practical any additional information and documentary material that may be required or requested by the PSCU, PSCW and PUCI and any other applicable Governmental Authority and (C) use its reasonable best efforts to take or cause to be taken all other actions consistent with this Section 5.4 as necessary to obtain any necessary approvals, consents, waivers, permits, authorizations or other actions or non-actions from the PSCU, PSCW and PUCI as soon as practicable. Promptly after the date of this Agreement, at Parent’s reasonable request, the Company and Parent agree to meet and confer in good faith to discuss and consider combining or consolidating any outstanding or planned rate cases with respect to the Required Statutory Approvals and filings set forth in Section 5.4(b)(ii)(A).

(c) The Company, Parent and Merger Sub shall, subject to applicable Law relating to the exchange of information: (i) promptly notify the other parties hereto of (and if in writing, furnish the other parties with copies of) any communication to such Person from a third person or any Governmental Authority regarding the filings and submissions described in Section 5.4(a) and permit the others to review and discuss in advance (and to consider in good faith any comments made by the others in relation to) any proposed written response to any communication from a Governmental Authority regarding the filings and submissions described in Section 5.4(a), (ii) keep the others reasonably informed of any developments, meetings or discussions with any Governmental Authority in respect of any filings, investigation or inquiry concerning the Transactions and (iii) not independently participate in any meeting or discussions with a Governmental Authority in respect of any filings, investigation or inquiry concerning the Transactions without giving the other party prior notice of such meeting or discussions and, unless prohibited by such Governmental Authority, the opportunity to attend or participate;

34

provided, that the parties shall be permitted to redact any correspondence, filing, submission or communication to the extent such correspondence, filing, submission or communication contains competitively or commercially sensitive information, including information relating to the valuation of the Transactions.

(d) In furtherance and not in limitation of the foregoing, but subject to the other terms and conditions of this Section 5.4, Parent, Merger Sub and the Company agree to take promptly any and all steps necessary to avoid, eliminate or resolve each and every impediment and obtain all clearances, consents, approvals and waivers under Antitrust Laws or other applicable Laws that may be required by any Governmental Authority, so as to enable the parties to close the Transactions as soon as practicable (and in any event no later than three (3) Business Days prior to the End Date), including committing to and effecting, by consent decree, hold separate orders, trust, or otherwise, (i) the sale, license, holding separate or other disposition of assets or businesses of Parent or Company or any of their respective Subsidiaries, (ii) terminating, relinquishing, modifying, or waiving existing relationships, ventures, contractual rights, obligations or other arrangements of Parent or Company or their respective Subsidiaries and (iii) creating any relationships, ventures, contractual rights, obligations or other arrangements of Parent or Company or their respective Subsidiaries (each a “Remedial Action”); provided, however, that any Remedial Action may, at the discretion of the Company or Parent, be conditioned upon consummation of the Transactions.

(e) In furtherance and not in limitation of the foregoing, but subject to the other terms and conditions of this Section 5.4, in the event that any litigation or other administrative or judicial action or proceeding is commenced, threatened or is reasonably foreseeable challenging any of the Transactions and such litigation, action or proceeding seeks, or would reasonably be expected to seek, to prevent, materially impede or materially delay the consummation of the Transactions, Parent shall use reasonable best efforts to take any and all action, including a Remedial Action, to avoid or resolve any such litigation, action or proceeding as promptly as practicable (and in any event shall commence such action no later than three (3) Business Days prior to the End Date). In addition, each of the Company, Parent and Merger Sub shall cooperate with each other and use its respective reasonable best efforts to contest, defend and resist any such litigation, action or proceeding and to have vacated, lifted, reversed or overturned any ruling, decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents, delays, interferes with or restricts consummation of the Transactions as promptly as practicable and in any event no later than three (3) Business Days prior to the End Date.

(f) From the date hereof until the earlier of the Effective Time and the date this Agreement is terminated pursuant to Article VII, neither Parent, Merger Sub nor Company shall, nor shall they permit their respective Subsidiaries to, acquire or agree to acquire any rights, assets, business, Person or division thereof (through acquisition, license, joint venture, collaboration or otherwise), if such acquisition, would reasonably be expected to materially increase the risk of not obtaining any applicable clearance, consent, approval or waiver under Antitrust Laws or other applicable Laws with respect to the Transactions, or would reasonably be expected to materially prevent or prohibit or impede, interfere with or delay obtaining any applicable clearance, consent, approval or waiver under Antitrust Laws or other applicable laws with respect to the Transactions.

35

(g) Notwithstanding the obligations set forth in this Agreement, Parent and its Affiliates shall not be required to, and, without the prior written consent of Parent (which consent may be withheld at Parent’s sole discretion) the Company shall not, and shall cause its Subsidiaries not to, in connection with obtaining any consent or approval of any Governmental Authority in connection with this Agreement or the transactions contemplated hereby, offer or accept, or agree, commit to agree or consent to, any undertaking, term, condition, liability, obligation, commitment or sanction (including any Remedial Action), that constitutes a Burdensome Condition.

(h) Parent shall promptly notify the Company and the Company shall notify Parent of any notice or other communication from any Governmental Authority alleging that such Governmental Authority’s consent is or may be required in connection with or as a condition of the Merger.

Section 5.5 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 Parent and the Company. Following such initial press release, Parent and the Company shall consult with each other before issuing, and give each other the opportunity to review and comment upon, any press release or other public statements with respect to the Transactions and shall not issue any such press release or make any such public statement prior to such consultation, except as such party may reasonably conclude may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system (and then only after as much advance notice and consultation as is feasible); provided, however, that the restrictions set forth in this Section 5.5 shall not apply to any release or public statement (a) made or proposed to be made by the Company in connection with a Takeover Proposal, a Superior Proposal or a Company Adverse Recommendation Change or any action taken pursuant thereto, (b) in connection with any dispute between the parties regarding this Agreement or the Transactions or (c) that is not inconsistent in any material respects with the prior public disclosures regarding the Transactions.

Section 5.6 Access to Information; Confidentiality.

(a) Subject to applicable Laws relating to the exchange of information, from the date hereof until the earlier of the Effective Time or the date on which this Agreement is terminated in accordance with its terms, the Company shall afford to Parent and its Representatives reasonable access (at Parent’s sole cost and expense) during normal business hours and upon reasonable advance notice to the Company’s and its Subsidiaries’ properties and personnel (but excluding for the conduct of Phase I or Phase II environmental assessments or testing), books, Contracts and records and the Company and its Subsidiaries shall furnish promptly to Parent such information concerning its business and properties as Parent may reasonably request (other than any publicly available document filed by the Company and its Subsidiaries pursuant to the requirements of federal or state securities Laws); provided that Parent and its Representatives shall conduct any such activities in such a manner as not to interfere unreasonably with the business or operations of the other party; provided, further, (x) that the Company shall not be obligated to provide such access or information if the Company determines, in its reasonable judgment, that doing so would violate applicable Law or a Contract or obligation of confidentiality owing to a third party, jeopardize the protection of the attorney-

36

client privilege, or expose such party to risk of liability for disclosure of sensitive or personal information and (y) the conduct of such activities shall be subject to the rights and obligations of the Company referred to in the final proviso of the final sentence of Section 5.4(c) hereof. Without limiting the foregoing, the Company shall, and shall cause its Subsidiaries to, provide commercially reasonable assistance to Dominion Midstream Partners (including the Conflicts Committee of DMPGP) in connection with the preparation of financial statements that may be required in connection with any proposed contribution of Questar Pipeline or any of its assets to Dominion Midstream Partners. Until the Effective Time, the information provided will be subject to the terms of the confidentiality letter agreement, dated as of December 30, 2015, between Parent and the Company (as it may be amended from time to time, the “Confidentiality Agreement”), and, without limiting the generality of the foregoing, Parent and Company shall not, and Parent and Company shall cause their respective Representatives not to, use such information for any purpose unrelated to the consummation of the Transactions.

(b) If this Agreement is terminated pursuant to Section 7.1, the Confidentiality Agreement shall automatically be deemed to be amended and restated such that (i) the “Restricted Period” for all purposes of the Confidentiality Agreement shall be the period of eighteen (18) months from the date of such termination, as if the Parties had never entered into this Agreement, and (ii) the other provisions of the Confidentiality Agreement shall remain in force and effect for a period of two (2) years after such termination, as if the parties hereto had never entered into this Agreement.

Section 5.7 Takeover Laws. If any Takeover Statute becomes applicable to the Transactions, the Company and the Company Board will use reasonable best efforts to ensure that such Transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Transactions.

Section 5.8 Indemnification and Insurance.

(a) From and after the Effective Time, Parent shall, and shall cause the Surviving Corporation to, (i) indemnify, defend and hold harmless each current and former director, officer and employee of the Company and any of its Subsidiaries and each person who served as a director, officer, member, trustee or fiduciary of another corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise if such service was at the request or for the benefit of the Company or any of its Subsidiaries (each, an “Indemnitee” and, collectively, the “Indemnitees”) against all claims, liabilities, losses, damages, judgments, fines, penalties, costs (including amounts paid in settlement or compromise) and expenses (including fees and expenses of legal counsel) in connection with any actual or threatened claim, suit, action, proceeding or investigation (whether civil, criminal, administrative or investigative) (each, a “Claim”), whenever asserted, arising out of, relating to or in connection with any action or omission relating to their position with the Company or its Subsidiaries occurring or alleged to have occurred before or at the Effective Time (including any Claim relating in whole or in part to this Agreement or the Transactions), to the fullest extent permitted under applicable Law and (ii) assume all obligations of the Company and its Subsidiaries to the Indemnitees in respect of limitation of liability, exculpation, indemnification and advancement of expenses as provided in (A) the Company Charter Documents and the respective organizational documents of each of the

37

Company’s Subsidiaries as currently in effect and (B) any indemnification agreements with an Indemnitee listed on Section 5.8(a) of the Company Disclosure Schedule, which shall in each case survive the Transactions and continue in full force and effect to the extent permitted by applicable Law. Without limiting the foregoing, at the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, cause the articles of incorporation and bylaws of the Surviving Corporation to include provisions for limitation of liabilities of directors and officers, indemnification, advancement of expenses and exculpation of the Indemnitees no less favorable to the Indemnitees than as set forth in the Company Charter Documents in effect on the date of this Agreement, which provisions shall not be amended, repealed or otherwise modified in a manner that would adversely affect the rights thereunder of the Indemnitees except as required by applicable Law.

(b) From and after the Effective Time, Parent shall, and shall cause the Surviving Corporation to, pay and advance to an Indemnitee any expenses (including fees and expenses of legal counsel) in connection with any Claim relating to any acts or omissions covered under this Section 5.8 or the enforcement of an Indemnitee’s rights under this Section 5.8 as and when incurred to the fullest extent permitted under applicable Law, provided that the person to whom expenses are advanced provides an undertaking to repay such expenses if it is ultimately determined by a court of competent jurisdiction that such Indemnitee is not entitled to indemnification for such matter.

(c) For a period of six (6) years from the Effective Time, Parent shall cause to be maintained in effect coverage not materially less favorable than the coverage provided by the policies of directors’ and officers’ liability insurance and fiduciary liability insurance in effect as of the date hereof maintained by the Company and its Subsidiaries with respect to matters arising on or before the Effective Time either through the Company’s existing insurance provider or another provider reasonably selected by Parent; provided, however, that, after the Effective Time, Parent shall not be required to pay annual premiums in excess of 300% of the annual premium currently paid by the Company in respect of the coverages required to be obtained pursuant hereto, but in such case shall purchase as much coverage as reasonably practicable for such amount; provided, further, that in lieu of the foregoing insurance coverage, the Company may purchase “tail” insurance coverage, at a cost no greater than the aggregate amount which Parent would be required to spend during the six–year period provided for in this Section 5.8(c), that provides coverage not materially less favorable than the coverage described above to the insured persons than the directors’ and officers’ liability insurance and fiduciary liability insurance coverage currently maintained by the Company and its Subsidiaries as of the date hereof with respect to matters arising on or before the Effective Time.

(d) The provisions of this Section 5.8 are (i) intended to be for the benefit of, and shall be enforceable by, each Indemnitee, his or her heirs and his or her representatives from and after the Effective Time, and (ii) in addition to, and not in substitution for or limitation of, any other rights to indemnification or contribution that any such Person may have by contract or otherwise. The obligations of Parent and the Surviving Corporation under this Section 5.8 shall not be terminated or modified in such a manner as to adversely affect the rights of any Indemnitee to whom this Section 5.8 applies unless (A) such termination or modification is required by applicable Law or (B) the affected Indemnitee shall have consented in writing to such termination or modification (it being expressly agreed that the Indemnitees to whom this Section 5.8 applies shall be third party beneficiaries of this Section 5.8).

38

(e) In the event that Parent, the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of Parent and the Surviving Corporation shall assume all of the obligations thereof set forth in this Section 5.8.

Section 5.9 Transaction Litigation. Each of Parent and the Company shall notify the other promptly of the commencement of any shareholder litigation relating to this Agreement or the Transactions of which it has received notice or which, to the Knowledge of the Company, is threatened (“Transaction Litigation”). The Company shall give Parent the opportunity to participate in, but not control, the defense or settlement of any Transaction Litigation, and no such settlement of any Transaction Litigation shall be agreed to by the Company without Parent’s prior written consent, such consent not to be unreasonably withheld, conditioned or delayed.

Section 5.10 Section 16. Prior to the Effective Time, each of the Company, Parent and Merger Sub shall take all such steps reasonably necessary to cause any dispositions of Company Common Stock (including derivative securities with respect to Company Common Stock) directly resulting from the Merger by each individual who will be subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company immediately prior to the Effective Time to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 5.11 Employee Matters.

(a) Until the later of one (1) year following the Effective Time or December 31, 2017 (the “Continuation Period”), Parent shall provide, or shall cause to be provided, to each individual who is employed by the Company or any of its Subsidiaries (including the Surviving Corporation and its Subsidiaries) immediately prior to the Effective Time (each, a “Company Employee”) annual base salary and base wages, target annual cash bonuses (subject to the satisfaction of performance criteria determined by Parent, provided that such performance criteria shall be no less favorable than for other similarly situated employees of Parent and its Subsidiaries) and target long-term incentive compensation opportunities (which shall be in a form and subject in whole or in part to the satisfaction of performance criteria as determined by Parent, provided that the form of such awards and the performance criteria shall be no less favorable than for other similarly situated employees of Parent and its Subsidiaries) and employee benefits (excluding any voluntary elective deferral component of any nonqualified deferred compensation plan) that, in each case, are no less favorable in the aggregate than such annual base salary and base wages, target annual cash bonuses and target long-term incentive compensation opportunities and employee benefits provided to the Company Employees immediately prior to the Effective Time; provided, however, that annual cash bonus and any long-term incentive compensation opportunities shall not be required to be provided for performance periods commencing before January 1, 2017 and, if the Effective Time occurs in 2017, any annual cash bonus opportunity may be pro-rated based on days of service during such

39

performance period on and after the Closing Date. Notwithstanding any other provision of this Agreement to the contrary and without limiting the generality of the foregoing, Parent shall or shall cause the Surviving Corporation to provide any Company Employee whose employment terminates under circumstances entitling the Company Employee to severance under the applicable Parent severance plan, program or arrangement (or any successor thereto) (collectively, the “Parent Severance Programs”) during the Continuation Period (including, for avoidance of doubt, any Company Employee whose employment terminates under such circumstances in an individual or one-off termination and regardless of whether any other employee is affected) or, with respect to the Company Employees identified on Section 5.11(a) of the Company Disclosure Schedule, whose employment terminates for “Good Reason” (as defined in Section 5.11(a) of the Company Disclosure Schedule), and who signs a general release of claims on a form satisfactory to Parent, with severance benefits no less favorable than those provided to similarly situated employees of Parent and its Subsidiaries under the Parent Severance Programs, and, for the avoidance of doubt, taking into account all of the Company Employee’s service with the Company and its Subsidiaries (and their predecessors) for purposes of determining the levels of severance benefits to be provided to such Company Employee under the Parent Severance Programs; provided, however, that no Company Employee who is covered by the Company Executive Severance Compensation Plan or any other severance plan or arrangement with the Company or its Subsidiaries that provides for more favorable severance payments and benefits than the Parent Severance Program shall be eligible for coverage under the Parent Severance Program.

(b) For all purposes (including purposes of vesting, eligibility to participate and level of benefits but not for purposes of defined benefit pension accrual) under the employee benefit plans of Parent and its Subsidiaries providing benefits to any Company Employee after the Effective Time (including the Company Plans) (the “New Plans”), each Company Employee shall be credited with his or her years of service with the Company and its Subsidiaries and their respective predecessors before the Effective Time, to the same extent as such Company Employee was entitled, before the Effective Time, to credit for such service under any Company Plan in which such Company Employee participated or was eligible to participate immediately prior to the Effective Time; provided, however, that the foregoing shall not apply to the extent that its application would result in a duplication of benefits with respect to the same period of service and, provided further, that no Company Employee shall be entitled based on such prior credited service or otherwise to participate in any frozen or grandfathered plan or benefit formula of Parent or any of its Subsidiaries that would not be offered to employees first hired by Parent or its Subsidiaries after the Effective Time. Furthermore, to the extent a Company Employee or a “Company Retired Employee” (as defined below) becomes eligible to participate in Parent’s or its Subsidiaries’ retiree medical plan, for all purposes (including purposes of vesting, eligibility to participate and level of benefits) under the retiree medical plan of Parent and its Subsidiaries, each (x) Company Employee and (y) former employee of the Company or any of its Subsidiaries whose employment with the Company or any of its Subsidiaries ended as a result of such former employee’s retirement and who is eligible to participate in the Company’s retiree medical plan as of the Effective Time (the “Company Retired Employees”), shall be credited with his or her years of service with the Company and its Subsidiaries and their respective predecessors before the Effective Time, to the same extent as such Company Employee or Company Retired Employee was entitled, immediately before the Effective Time, to credit for such service under the Company’s retiree medical plan as of the Effective Time; provided that any individual who

40

waived participation in the Company’s retiree medical plan but is still eligible, pursuant to the terms of such retiree medical plan as in effect on the date hereof, to participate in such plan, shall remain eligible to participate in such plan but shall not be or become eligible to participate in any retiree medical plan of the Parent and its Subsidiaries (other than the Surviving Corporation) and provided further that the parties agree to the matters set forth on Section 5.11(c) of the Company Disclosure Schedule. Parent shall, or shall cause an Affiliate to, provide postretirement medical benefits to Eligible Retirees (as defined below) that (i) during the Continuation Period are no less favorable than those provided under the Company’s postretirement medical program in effect as of December 31, 2015 (the “Company Retiree Health Plan”) and (ii) following the Continuation Period are no less favorable than either (1) those provided under the Company Retiree Health Plan or (2) those provided to similarly situated, as applicable, employees and retirees who participate in the post-retirement programs of Parent or its Subsidiaries (other than the Surviving Corporation). “Eligible Retirees” means Company Retired Employees and Company Employees who are or become eligible to participate in the Company Retiree Health Plan as in effect on January 1, 2016. In addition, and without limiting the generality of the foregoing, (i) each Company Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan is replacing comparable coverage under a Company Plan in which such Company Employee participated immediately before the Effective Time (such plans, collectively, the “Old Plans”), and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Company Employee, Parent shall use commercially reasonable efforts to cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such Company Employee and his or her covered dependents, to the extent such conditions were inapplicable or waived under the comparable Old Plans of the Company or its Subsidiaries in which such Company Employee participated immediately prior to the Effective Time. Parent shall use commercially reasonable efforts to cause any eligible expenses incurred by any Company Employee and his or her covered dependents during the portion of the plan year of the Old Plan ending on the date such Company Employee’s participation in the corresponding New Plan begins to be taken into account under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Company Employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan.

(c) Without limiting the generality of Section 5.11(a), from and after the Effective Time, Parent shall cause the Surviving Corporation and its Subsidiaries to assume and honor and continue all obligations under the Company Plans and compensation and severance arrangements and agreements in accordance with their terms as in effect immediately before the Effective Time, and the Transactions shall be deemed to constitute a “change in control,” “change of control”, “corporate transaction” or similar words to such effect under such Company Plans, arrangements or agreements.

(d) To the extent that the Effective Time occurs (i) in 2016 or (ii) following the end of the 2016 performance period with respect to the Company’s Annual Incentive Plans or any other applicable annual bonus plan, but, in each case, prior to payment of the bonuses for such 2016 performance period, Parent shall cause the Surviving Corporation to pay to each Company Employee the greater of (i) the Company Employee’s target bonus for such 2016 performance period and (ii) the bonus to which the Company Employee would be entitled for

41

such 2016 performance period based on actual performance. In addition, in the event that the Effective Time occurs in 2017, at the Effective Time, Parent shall cause the Surviving Corporation to pay to each Company Employee a pro-rata portion of any bonus that such Company Employee would have been entitled to receive under the Company’s Annual Incentive Plans and any other applicable annual bonus plan for the 2017 performance period based on the Company Employee’s target bonus for such 2017 performance period.

(e) Notwithstanding anything to the contrary herein, the provisions of this Section 5.11 are solely for the benefit of the parties to this Agreement, and no provision of this Section 5.11 is intended to, or shall, constitute the establishment or adoption of or an amendment to any Company Plans or any employee benefit plan of Parent, Surviving Corporation or their respective Subsidiaries, and no Company Employee or any other individual associated therewith shall be regarded for any purpose as a third-party beneficiary of this Agreement or have the right to enforce the provisions hereof including in respect of continued employment (or resumed employment). Unless otherwise specifically provided in this Section 5.11, no provision of this Agreement shall constitute a limitation on Parent’s, the Surviving Corporation’s or their respective Subsidiaries’ right to amend, modify or terminate, after the Effective Time, any Company Plan or any employee benefit plan of Parent, Surviving Corporation or their respective Subsidiaries. Nothing contained herein shall alter the at-will employment relationship of any Company Employee.

Section 5.12 Merger Sub and Surviving Corporation. Parent shall take all actions necessary to (a) cause Merger Sub and the Surviving Corporation to perform promptly their respective obligations under this Agreement and (b) cause Merger Sub to consummate the Merger on the terms and conditions set forth in this Agreement. Prior to the Effective Time, Merger Sub shall not engage in any activity of any nature except for activities related to or in furtherance of the Transactions.

Section 5.13 No Control of Other Party’s Business. Nothing contained in this Agreement is intended to give Parent or Merger Sub, directly or indirectly, the right to control or direct the Company’s or its Subsidiaries’ operations prior to the Effective Time. Prior to the Effective Time, the Company shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

Section 5.14 Stock Exchange Delisting; Exchange Act Deregistration. Before the Effective Time, the Company shall cooperate with Parent and use its 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 Laws and rules and policies of the NYSE and SEC to enable the delisting by the Surviving Corporation of the Company Common Stock from the NYSE and the deregistration of the Company Common Stock under the Exchange Act as promptly as practicable after the Effective Time, and in any event no more than ten (10) days after the Closing Date.

Section 5.15 Advice of Changes. From and after the date of this Agreement until the Effective Time, each of Parent and the Company will, to the extent not in violation of any applicable Law, promptly notify the other of (a) any circumstance, development, change, event, occurrence or effect of which it has Knowledge that has had or that would reasonably be

42

expected to have a Parent Material Adverse Effect or a Company Material Adverse Effect, as the case may be, or (b) any material breach of any of its representations, warranties or covenants contained in this Agreement that would reasonably be expected to give rise to a failure of any condition to the obligations of the other party to effect the Merger set forth in Article VI to be satisfied, provided that (i) no such notification will affect the representations, warranties or covenants of the parties or the conditions to the obligations of the parties under this Agreement and (ii) in no event shall the failure to comply with this Section 5.15 give rise to a failure of any condition set forth in Article VI to be satisfied.

Section 5.16 Financing Cooperation

(a) The Company shall, and shall cause the Subsidiaries of the Company to, (i) provide commercially reasonable assistance with the preparation of and any discussions regarding the business, financial statements, and management discussion and analysis of the Company and the Subsidiaries of the Company, all for use in connection with any debt or equity financing to be obtained by Parent or any Subsidiary of the Parent, including any registration statement filed with the SEC in anticipation thereof (the “Financing”, which term shall include, without limitation, the Transaction Financing) where Parent determines that the inclusion of such information is required or desirable, and (ii) request that its independent accountants provide customary and reasonable assistance to Parent or any Subsidiary of Parent, as applicable, in connection with providing customary comfort letters in connection with the Financing; provided, further, that nothing in this Agreement shall require the Company to cause the delivery of (A) legal opinions or reliance letters or any certificate as to solvency or any other certificate necessary for the Financing, other than as allowed by the preceding clause (ii), (B) any audited financial information or any financial information prepared in accordance with Regulation S-K or Regulation S-X under the Securities Act or any financial information in a form not customarily prepared by the Company with respect to any period or (C) any financial information with respect to a month or fiscal period that has not yet ended or has ended less than forty-five (45) days prior to the date of such request.

(b) Notwithstanding anything to the contrary contained in this Agreement (including this Section 5.16): (i) nothing in this Agreement (including this Section 5.16) shall require any such cooperation to the extent that it would (A) require the Company to pay any commitment or other fees, reimburse any expenses or otherwise incur any liabilities or give any indemnities prior to the Closing, (B) unreasonably interfere with the ongoing business or operations of the Company or any of the Subsidiaries of the Company, (C) require the Company or any of the Subsidiaries of the Company to enter into or approve any agreement or other documentation effective prior to the Closing or agree to any change or modification of any existing agreement or other documentation that would be effective prior to the Closing, (D) require the Company to provide pro forma financial statements or pro forma adjustments reflecting the Financing or any description of all or any component of the Financing (it being understood that the Company shall use reasonable best efforts to assist in preparation of pro forma financial adjustments to the extent otherwise relating to the Company and required by the Financing), (E) require the Company or the Subsidiaries of the Company to provide pro forma financial statements or pro forma adjustments reflecting transactions contemplated or required hereunder (it being understood that the Company shall use reasonable best efforts to assist in preparation of pro forma financial adjustments to the extent otherwise relating to the Company

(c) Parent shall (i) promptly reimburse the Company for all reasonable and out-of-pocket costs or expenses (including reasonable and documented costs and expenses of counsel and accountants) incurred by the Company, the Subsidiaries of the Company and any of its or their Representatives in connection with any cooperation provided for in this Section 5.16 and (ii) indemnify and hold harmless the Company, the Subsidiaries of the Company or any of its and their Representatives against any claim, loss, damage, injury, liability, judgment, award, penalty, fine, Tax, cost (including cost of investigation), expense (including fees and expenses of counsel and accountants) or settlement payment incurred as a result of, or in connection with, any cooperation provided for in this Section 5.16 or the Financing and any information used in connection therewith, unless the Company acted in bad faith or with gross negligence and other than in the case of fraud.

(d) Without limiting the generality of the foregoing, promptly following Parent’s request, the Company shall deliver to each of the lenders under the Company’s and its Subsidiaries’ existing short and long-term Indebtedness (the “Existing Loan Lenders”) a notice (an “Existing Loan Notice”) prepared by Parent, in form and substance reasonably acceptable to the Company, notifying each of the Existing Loan Lenders of this Agreement and the contemplated Merger.

46

further, that neither the Company nor Parent may terminate this Agreement or extend the End Date pursuant to this Section 7.1(b)(i) if it (or, in the case of Parent, Merger Sub) is in breach of this Agreement and such breach has primarily caused or resulted in either (1) the failure to satisfy the conditions to its obligations to consummate the Closing set forth in Article VI prior to the End Date or (2) the failure of the Closing to have occurred prior to the End Date;

Exhibit 99.2

February 1, 2016

Dominion Resources, Questar Corporation to Combine

•  Premium addition to Dominion’s existing portfolio of high-performing,

regulated energy infrastructure assets

•    Transaction would be earnings accretive and supportive of Dominion’s credit ratings targets

•    Adds to Dominion’s inventory of top-quality, low-risk assets available for Dominion Midstream

•        Transaction to benefit Questar customers as focus remains on safe, efficient, reliable operations

•      Combined company would serve about 4.8 million electric & gas customer accounts in seven states

RICHMOND, Va. – Dominion Resources, Inc. (NYSE: D) and Questar Corporation (NYSE: STR) today announced an agreement for the companies to combine, in an all-cash transaction in which Dominion has agreed to pay Questar shareholders $25 per share – about $4.4 billion – and assume Questar’s outstanding debt.

The transaction would be accretive to Dominion upon closing – expected by year-end 2016 – with limited impact on the company’s balance sheet. Dominion intends to finance the transaction in a manner that supports the company’s existing credit ratings targets, using equity, mandatory convertibles and debt at Dominion, and equity at Dominion Midstream Partners, LP (NYSE: DM). The Dominion-Questar combination also is expected to support Dominion’s 2017 earnings growth rate and allow the company to reach the top of or exceed its 2018 growth targets.

Questar, headquartered in Salt Lake City, Utah, is a natural gas distribution, pipeline, storage and cost-of-service gas supply company. It serves nearly 1 million homes and businesses in Utah, Wyoming and Idaho, with approximately 97 percent of those customer accounts in Utah. Questar employs about 1,700 people and has about $4.2 billion in assets, including approximately 27,500 miles of gas distribution pipeline, 3,400 miles of gas transmission pipeline and 56 billion cubic feet of working gas storage. Its regional cost-of-service gas supply business has provided reliable supply and saved Questar Gas customers more than $1 billion over the past 35 years under a public service commission-approved framework.

Thomas F. Farrell II, chairman, president and chief executive officer of Dominion, said:

“Dominion is very pleased to join with Questar. Like Dominion, Questar has a history of safe and reliable operations, integrity and a firm commitment to its employees and the communities it serves. Questar’s customers can count on a continuation of the high-quality service they have enjoyed for years.

“This addition is well-aligned with Dominion’s existing strategic focus on core regulated energy infrastructure operations. Questar boasts best-in-sector customer growth in states with strong pro-business credentials and constructive regulatory environments. These high-performing regulated assets will improve Dominion’s balance between electric and gas operations and provide enhanced scale and diversification into Questar’s regulatory jurisdictions.

“Of note, Dominion Midstream investors will benefit from the addition of Questar, as it is expected to contribute more than $425 million of EBITDA to Dominion’s inventory of top-quality, low-risk MLP-eligible assets, supporting Dominion Midstream’s targeted annual cash distribution growth rate of 22 percent.

“Questar is the ideal mix for Dominion shareholders and Dominion Midstream unitholders alike.”

Ron Jibson, chairman, president and chief executive officer of Questar, said:

“Questar is excited to be joining the Dominion family of companies and serve as the hub of its Western operations. Our similar cultures and commitment to customers, shareholders, communities and employees make this a win-win transaction. Dominion’s reputation among its peers and analysts is unmatched. We’re proud to become part of America’s most-admired gas and electric utility.”

Adds geographic diversity to Dominion portfolio

Questar would provide enhanced geographic diversity to Dominion’s natural gas operations. Dominion’s existing operations lie in the heart of the mid-Atlantic, whereas Questar’s system is the “hub of the Rockies” and a principal source of gas supply to Western states. Dominion expects the value of the Questar pipeline system to rise over time as Utah and other Western states seek to comply with the requirements of the U.S. Environmental Protection Agency’s Clean Power Plan and meet state-mandated renewable standards, with increasing reliance on low-carbon, gas-fired electric generation.

The combined company would serve about 2.5 million electric utility customers and 2.3 million gas utility customers in seven states. It also would operate more than 15,500 miles of natural gas transmission, gathering and storage pipelines, one of the nation’s largest natural gas storage systems, and approximately 24,300 megawatts of generation.

Separate from this transaction, Dominion has committed about $1 billion for three solar generating facilities located in Beaver, Iron and Millard counties, Utah. These solar facilities are backed by long-term power purchase agreements with local electric utilities.

Terms of transaction & advisers

Upon transaction closing, Questar shareholders will receive $25 in cash for each share of Questar common stock. This represents an approximate 30 percent premium to the volume-weighted average stock price of Questar’s last 20 trading days ended Jan. 29, 2016.

Pending approvals, Questar will operate as a first-tier, wholly owned subsidiary of Dominion and maintain its significant presence, local management structure and headquarters in Salt Lake City.

Dominion has also agreed to increase community involvement and charitable investment in the communities currently served by Questar.

The transaction requires approval of Questar’s shareholders and clearance from the Federal Trade Commission under the Hart-Scott-Rodino Act. Questar and Dominion also will file for review and approval, if required, from the Utah Public Service Commission and the Wyoming Public Service Commission, and provide information regarding the transaction to the Idaho Public Utilities Commission.

RBC Capital Markets, LLC, and Mizuho Bank, Ltd., have provided committed financing and are acting in the role of financial advisers to Dominion. Goldman, Sachs & Co. served as the exclusive financial adviser to Questar.

McGuireWoods LLP served as legal counsel to Dominion and Kirkland & Ellis LLP served as legal counsel to Questar.

Email from Thomas F. Farrell II, President, Chairman and CEO of Dominion Resources, Inc., to Questar Corporation employees

February 1, 2016

Dear Questar employees,

On behalf of Dominion’s employees, I want to tell you how excited and pleased we are to join forces with the people of Questar. We see this as a natural fit, a combination of two companies with similar philosophies and ways of doing business that benefit employees, customers, communities and shareholders.

The first thing you should know about Dominion is our core values: Safety, Ethics, Excellence and One Dominion – our phrase for teamwork and knowing where you fit in the big picture. These values are very similar to the core beliefs and values you live by at Questar. With that as a common starting point, it should make joining our companies all the easier.

We also share a commitment to service. This includes providing safe and reliable energy to our customers, treating each other fairly and with respect, providing a fair return to our investors, and giving back to our communities. And we share a commitment to our employees. Forbes magazine recently recognized Dominion as America’s best employer in our industry.

In case you do not know Dominion, we are based in Richmond, Virginia. As one of the largest companies in the electric and natural gas industry, we deliver energy to about 3.8 million homes and businesses. We have been in the natural gas business for more than a century. Along with gas distribution operations in Ohio and West Virginia, Dominion owns a growing natural gas pipeline network that benefits from its position over the Marcellus and Utica shales. We also operate one of the nation’s largest natural gas storage systems and have an LNG export facility under construction.

We are no strangers to your part of the country. Dominion has about $1 billion invested in three solar farms in Utah. And, we were active for a number of years in the natural gas exploration and production business in the Rocky Mountains.

Joining with Dominion will enhance Questar’s ability to act on attractive growth opportunities. For example, we expect the value of the Questar pipeline system to rise over time as Utah and other nearby states seek to comply with the U.S. Environmental Protection Agency’s Clean Power Plan and meet state-mandated renewable standards. That will bring increasing reliance on low-carbon, gas-fired electric generation.

This is a tremendous opportunity for us all, as our combined companies open the door to even more growth through new investments and economies of scale. And as a unified company, we have the opportunity to share best practices. We have much we can learn from each other.

One other thing I want to address in today’s announcement is our expectation that some Questar assets would be prime candidates to be added to our Dominion Midstream master limited partnership (MLP). From an employee standpoint, moving certain assets into our MLP should be viewed as a non-event. Dominion employees operate assets placed in Dominion Midstream in virtually the same manner as they operate our other assets. It is really just a financing tool to maximize the value of the assets.

I and other Dominion leaders look forward to meeting many of you soon. We will be working with your Questar leadership team to keep you informed and up to date as we proceed through the approval and integration process. We look forward to working with you in the months and years ahead.

Sincerely,

Tom Farrell

Dominion Chairman, President & CEO

Transcript of video from Thomas F. Farrell II, President, Chairman and CEO of Dominion Resources, Inc., to Questar Corporation employees

Hello. I’m Tom Farrell, chairman and CEO of Dominion Resources.

By now you’ve heard the news that Questar and Dominion propose to join forces, and I hope you’ve learned a bit about who we are.

Let me take this opportunity to tell you personally how pleased Dominion is to be a part of this strategic combination.

Questar has long had an excellent reputation in the energy industry. However, the more we learned about your company the more impressed we became.

It’s not just your top spot in the Public Utilities Fortnightly and J.D. Power rankings. We also learned about a top-quality workforce with a strong personal commitment to safety, reliable operations, cost-effective service, and community involvement.

We found an experienced and well-respected management team with a focus on customers and employees. We witnessed a proactive approach to pipeline safety and integrity. And we were impressed with the third-party recognition for responsible environmental stewardship – just to name a few things.

We look forward to sharing best practices at both companies. By learning from each other, we can improve operations and benefit our customers.

I think you’ll find there are more similarities than differences where it matters most. Dominion’s four core values – Safety, Ethics, Excellence and One Dominion – drive us in the same direction. For that reason, Dominion and Questar leadership believe our two companies are a natural fit.

I know you have many questions about Dominion and your future with us. We will work together with Questar to tell you as much as we can, as soon as we can.

One question is sure to be top of mind: how will Questar be run after the combination? Given your strong operating record and distance from Richmond, we expect Questar to operate under a local management structure.

Now, that’s not to say nothing will change. There are still many details to be worked out, and change is a part of life. But I assure you, Dominion is deeply committed to the regions in which we operate – and the same will be true after our combination is completed.

We plan to keep Questar’s headquarters in Salt Lake City. We also plan to increase community involvement and charitable investment in the communities that are currently served by Questar.

We know you are a tight-knit organization. That sense of trust and teamwork is a valuable component of your success. I think you will find that being part of a bigger company can also have its advantages, without losing the personal touch. More colleagues and corporate resources to provide help and ideas. Broader career opportunities. Buying power and other economies of scale to name just a few.

You are joining one of the largest companies in our industry. We believe it’s the best in our industry. Together, we will provide natural gas and electricity to almost 5 million homes and businesses, and operate an infrastructure system that will be the envy of our peers. And the best is yet to come. It is up to all of us to make that happen.

We at Dominion look forward to working with you through the transition and welcoming you to the family later this year.

Thank you.
