Item 1.01. Entry into a Material Definitive Agreement.

Merger Agreement

On September 15, 2019, SemGroup Corporation (“SemGroup” or the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Nautilus Merger Sub LLC, a Delaware limited liability company and a newly formed, wholly owned subsidiary of ET (“Merger Sub”) and Energy Transfer LP , a Delaware limited partnership (“ET”). On September 15, 2019, the board of directors of SemGroup, and the board of directors of ET’s general partner unanimously approved the Merger Agreement.

The Merger Agreement provides that, subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will merge with and into SemGroup (the “Merger”), with SemGroup continuing as the surviving company and a direct wholly owned subsidiary of ET. At the effective time of the Merger (the “Effective Time”), (a) each share of Class A Common Stock of SemGroup, par value of $0.01 per share, issued and outstanding immediately prior to the Effective Time (other than shares held by SemGroup in treasury and shares held directly by ET or Merger Sub, other than shares held by subsidiaries of the parties and other than shares held by any holder who properly exercises and perfects appraisal rights in respect of such shares) (such issued and outstanding shares, collectively, “Company Common Stock,” and each, a “Share”) will be converted into the right to receive (i) $6.80 in cash, without interest (the “Per Share Cash Amount”), and (ii) 0.7275 (the “Exchange Ratio”) common units representing limited partner interests in ET (the “ET Common Units,” and together with the Per Share Cash Amount, the “Merger Consideration”), and (b) each share of SemGroup Series A Cumulative Perpetual Convertible Preferred Stock, par value of $0.01 per share (the “Company Preferred Stock”), outstanding immediately prior to the Effective Time will, at the election of the holders of a majority of such shares of Company Preferred Stock in accordance with the Certificate of Designations of Series A Cumulative Perpetual Convertible Preferred Stock of the Company, filed with the Secretary of State of the State of Delaware on January 19, 2018 (the “Certificate of Designations”), either (i) convert into Shares immediately prior to the Effective Time pursuant to Section 8(c)(i) of the Certificate of Designations, (ii) be exchanged for a “Substantially Equivalent Security” (as defined in the Certificate of Designations) pursuant to Section 8(c)(ii) of the Certificate of Designations or (iii) be redeemed by the Company for cash at a price per Share equal to 101% of the Liquidation Preference (as defined in the Certificate of Designations) pursuant to Section 8(c)(iv) of the Certificate of Designations. Each holder of Shares issued upon conversion of shares of Company Preferred Stock will receive the Merger Consideration in exchange for such Shares.

Treatment of Company Equity Awards

Each SemGroup restricted share unit award outstanding immediately prior to the Effective Time will, whether vested or unvested, be assumed by ET as of the Effective Time and converted into a restricted share unit award on the same terms and conditions with respect to a number of ET Common Units equal to the product obtained by multiplying the number of Shares subject to such Company restricted share unit award immediately prior to the Merger by a ratio equal to the Per Share Cash Amount divided by the closing price of one ET Common Unit on the NYSE on the day prior to the Merger closing plus the Exchange Ratio (the “Equity Exchange Ratio”). Each converted restricted share unit award will fully accelerate upon the holder’s termination without cause, for good reason, or as a result of death or disability following closing of the Merger.

Each SemGroup restricted share award outstanding immediately prior to the Effective Time, whether vested or unvested, will be assumed by ET as of the Effective time and converted into a restricted unit award on the same terms and conditions with respect to a certain number of ET Common Units equal to the product obtained by multiplying the number of Shares subject to such Company restricted share award immediately prior to the Merger by the Equity Exchange Ratio. Each converted restricted unit award will fully accelerate upon the holder’s termination without cause, for good reason, or as a result of death or disability following closing of the Merger.

Notwithstanding the foregoing, each SemGroup restricted share unit or restricted share award held by a non-employee director will fully vest upon the Effective Time, and be cancelled in exchange for Merger Consideration.

2

Each SemGroup performance share unit award that is unvested as of immediately prior the Effective Time will be cancelled without consideration at the Effective Time, and each SemGroup performance share unit award that is vested as of immediately prior to the Effective Time, will be cancelled in exchange for the Merger Consideration at the Effective Time. The Compensation Committee of the Board of Directors of the Company has determined to vest all performance share unit awards outstanding on the date hereof as of immediately prior to the Effective Time at target performance levels.

Conditions to the Merger

The completion of the Merger is subject to various customary closing conditions, including, among other things, (i) the adoption of the Merger Agreement by holders of a majority of the outstanding shares of Company Common Stock and Company Preferred Stock (on an as-converted basis), voting as a single class, entitled to vote thereon, (ii) absence of any court order or regulatory injunction prohibiting completion of the Merger, (iii) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (iv) the effectiveness of the registration statement on Form S-4 that ET is obligated to file with the Securities and Exchange Commission (“SEC”) in connection with the issuance of ET Common Units in the Merger, (v) the authorization for listing of ET Common Units to be issued in the Merger on the New York Stock Exchange, and (vi) the accuracy of each party’s representations and warranties (subject to certain materiality qualifiers) and compliance by each party with its covenants under the Merger Agreement in all material respects.

Termination Rights

The Merger Agreement contains certain termination rights for both SemGroup and ET including, among other things: (i) by SemGroup or ET, if SemGroup fails to obtain the requisite approval of its stockholders necessary for the Merger; (ii) by SemGroup or ET, if the other party breaches or fails to perform any of its representations, warranties or covenants in the Merger Agreement that cannot be or is not cured in accordance with the terms of the Merger Agreement; (iii) by ET, in the event that the SemGroup board of directors makes a Change of Recommendation (as defined in the Merger Agreement); (iv) by ET, upon any willful breach by SemGroup of the non-solicitation covenant (as discussed further below under “—No Solicitation”); (v) by SemGroup if, prior to obtaining the requisite approval of its stockholders, SemGroup concurrently enters into a definitive agreement with respect to a Superior Offer (as defined in the Merger Agreement). If the Merger Agreement is terminated (A) by ET in accordance with clause (ii) due to SemGroup’s failure to hold the special stockholders’ meeting to approve the Merger, (B) pursuant to clause (iv), (C) pursuant to clause (iii) if an Acquisition Proposal (as defined in the Merger Agreement) has been made public or if SemGroup enters into an Acquisition Transaction (as defined in the Merger Agreement) within 12 months, or (D) pursuant to clause (v), then SemGroup will be required to pay ET a termination fee of $54,500,000 (the “Breakup Fee”) and if the Merger Agreement is terminated in accordance with clause (i) or clause (iv) where a Breakup Fee is not then payable, then SemGroup will be required to pay ET up to $27,250,000 for costs fees and expenses incurred by ET in connection with the Merger.

In addition to the foregoing termination rights, either party may terminate the Merger Agreement on or prior to June 30, 2020 if the Merger has not been consummated, or on or prior to September 30, 2020 if a governmental entity of competent jurisdiction prohibits or prevents the consummation of the Merger or all waiting periods under applicable competition laws have not expired, terminated or been approved, in which case either party may terminate. The parties may also mutually agree to terminate the Merger Agreement.

No Solicitation

SemGroup nor any of its affiliates is permitted, among other things, to solicit, initiate or knowingly encourage or facilitate, among other things, any inquiries, proposals or offers from any person which constitutes or may reasonably be expected to result in an Acquisition Proposal or engage in or participate in any discussions or negotiations regarding any such Acquisition Proposal. Notwithstanding this limitation, prior to receipt of the approval of the Company’s stockholders, the Company may, under certain circumstances, provide non-public information to and participate in discussions or negotiations with third parties with respect to certain unsolicited Acquisition Proposals if the SemGroup board of directors has determined in good faith, after consultation with its outside financial advisors and legal counsel, that the failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties. SemGroup’s board of directors may change its recommendation to its

3

shareholders (subject to ET’s right to terminate the Merger Agreement following such change in recommendation) in response to an Acquisition Proposal that it has determined, after consultation with its outside financial advisors and legal counsel, constitutes a superior proposal or in response to an intervening event if, in either case, the board of directors determines in good faith that the failure to take such action would be reasonably be expected to be inconsistent with its fiduciary duties.

Other Terms of the Merger Agreement

The Merger Agreement contains customary representations, warranties and covenants for a transaction of this nature. The Merger Agreement also contains customary pre-closing covenants, including the obligation of SemGroup and ET to conduct their respective businesses in the ordinary course of practice consistent with past practice and to refrain from taking certain specified actions without the consent of the other party.

The foregoing summary of the Merger Agreement and the transactions contemplated by the Merger Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, which is filed as Exhibit 2.1 to this Form 8-K and incorporated herein by reference.

They are not intended to provide any other factual information about SemGroup, ET or their respective subsidiaries or affiliates or equityholders. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of those agreements and as of specific dates; were solely for the benefit of the parties to the Merger Agreement; and may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made by each contracting party to the other for the purposes of allocating contractual risk between them that differ from those applicable to investors. Investors should be aware that the representations, warranties and covenants or any description thereof may not reflect the actual state of facts or condition of SemGroup, ET, Merger Sub or any of their respective subsidiaries, affiliates, businesses, or equityholders. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures by SemGroup or ET. Accordingly, investors should read the representations and warranties in the Merger Agreement not in isolation but only in conjunction with the other information about SemGroup or ET and their respective subsidiaries that the respective companies include in reports, statements and other filings they make with the SEC.

Support Agreement

Contemporaneously with the execution of the Merger Agreement, SemGroup, ET, Merger Sub, and WP SemGroup Holdco, LLC, a holder of approximately 85.72% of the issued and outstanding shares of SemGroup Preferred Stock (the “Stockholder”), entered into a support agreement (the “Support Agreement”). Pursuant to the Support Agreement, the Stockholder agreed to, among other things, vote all of its shares in SemGroup that it owns as of the record date for the SemGroup stockholder meeting (i) in favor of the adoption of the Merger Agreement, (ii) against any acquisition proposal, and (iii) against any action, agreement, transaction or proposal that is intended, would reasonably be expected or the result of which would reasonably be expected, to materially impede, interfere with, delay, postpone, discourage, frustrate the purposes of or adversely affect the Merger or the other transactions contemplated by the Merger Agreement. In addition, the Stockholder and SemGroup agreed to amend the Certificate of Designations related to the Company Preferred Stock (the “Amendment”) to provide for the redemption in cash of all of the shares of Company Preferred Stock in connection with the closing of the Merger at a price of 101% of the Liquidation Preference (as defined in the Certificate of Designations), and the Stockholder has agreed to make an election to have the shares of Company Preferred Stock redeemed at such price.

A copy of the Support Agreement is filed as Exhibit 10.1 to this report and is incorporated herein by reference. The foregoing description of the Support Agreement does not purport to be complete and is qualified in its entirety by reference to the Support Agreement. It is not intended to provide any other factual information about the parties or their respective subsidiaries and affiliates. The Support Agreement contains representations and warranties by each of the parties to the Support Agreement, which were made only for purposes of the Support Agreement and as of a specified date. The representations, warranties and covenants in the Support Agreement were

4

made solely for the benefit of the parties to the Support Agreement; may be subject to limitations agreed upon by the contracting parties; and may be subject to standards of materiality, applicable to the contracting parties that differ from those applicable to investors. 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, warranties and covenants may change after the date of the Support Agreement, which subsequent information may or may not be fully reflected in SemGroup’s or ET’s public disclosures.

Until surrendered as contemplated by this Section 2.2(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration (and any amounts to be paid pursuant to Section 2.1(e) or Section 2.2(c)) upon such surrender. No interest shall be paid or shall accrue on any amount payable pursuant to Section 2.1(e) or Section 2.2(c).

If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II.

(e)    Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments thereof) that remains undistributed to the former holders of Shares for one year after the Effective Time shall be delivered to Parent upon demand, and any holders of Shares who have not theretofore complied with this Article II shall thereafter look only to Parent for payment of their claim for the Merger Consideration, any cash in lieu of fractional Common Units pursuant to Section 2.1(e) and any distributions pursuant to Section 2.2(c).

If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration to be paid in respect of the Share represented by such Certificate as contemplated by this Article II.

To the extent that amounts are so withheld and paid over to the applicable Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of whom such deduction and withholding was made. If withholding is taken in Common Units, Parent, Merger Sub or the Exchange Agent (as applicable) shall be treated as having sold such Common Units for an amount of cash equal to the fair market value of such Common Units at the time of such deemed sale.

Parent has established and maintains disclosure controls and procedures and internal control over financial reporting (as such terms are defined in paragraphs (e) and (f), respectively, of Rule 13a-15 under the Exchange Act) as required by Rule 13a-15 under the Exchange Act. Parent’s disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed by Parent 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 the management of Parent GP 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. Management of Parent GP has completed an assessment of the effectiveness of Parent’s internal control over financial reporting in compliance with the requirements of Section 404 of the Sarbanes-Oxley Act for the year ended December 31, 2018, and such assessment concluded that such controls were effective. Based on its most recent evaluation of internal controls over financial reporting prior to the date hereof, management of Parent GP has disclosed to Parent’s auditors and the audit committee of the Board of Directors of Parent GP (i) any significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting that are reasonably likely to adversely affect in any material respect Parent’s ability to report financial information and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in Parent’s internal control over financial reporting, and each such deficiency, weakness and fraud so disclosed to auditors, if any, has been disclosed to the Company prior to the date hereof.

Section 4.7    Compliance with Law; Permits. (a) Parent and its Subsidiaries are in compliance with, and are not in default under or in violation of, any applicable Law, except where such non-compliance, default or violation would not have, individually or in the aggregate, a Parent Material Adverse Effect.

Parent shall also take any action required to be taken under any applicable state or provincial securities laws in connection with the issuance and reservation of Common Units in the Merger, and the Company shall furnish all information concerning the Company and the holders of Company Common Stock and Company Preferred Stock, or holders of a beneficial interest therein, as may be reasonably requested in connection with any such action. No filing of, or amendment or supplement to, the Form S-4 or the Proxy Statement/Prospectus will be made by Parent or the Company, as applicable, without the other’s prior consent (which shall not be unreasonably withheld, conditioned or delayed) and without providing the other party a

- 53 -

reasonable opportunity to review and comment thereon. Parent or the Company, as applicable, will advise the other promptly after it receives oral or written notice of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order, the suspension of the qualification of the Common Units issuable in connection with the Merger for offering or sale in any jurisdiction, or any oral or written request by the SEC for amendment of the Proxy Statement/Prospectus or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information, and will promptly provide the other with copies of any written communication from the SEC or any state securities commission. If at any time prior to the Effective Time any information relating to Parent or the Company, or any of their respective affiliates, officers or directors, is discovered by Parent or the Company which should be set forth in an amendment or supplement to any of the Form S-4 or the Proxy Statement/Prospectus, so that any of such documents 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 party that discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by law, disseminated to the stockholders of the Company.

(b)    The Company shall take all action necessary in accordance with applicable Laws and the Company Organizational Documents to duly give notice of, convene and hold a meeting of its stockholders, to be held as promptly as practicable after the Form S-4 is declared effective under the Securities Act, to consider the adoption of this Agreement (the “Company Stockholders’ Meeting”). The Company will, except in the case of a Change of Recommendation, through its Board of Directors, recommend that its stockholders adopt this Agreement and will use reasonable best efforts to solicit from its stockholders proxies in favor of the adoption of this Agreement and to take all other action necessary or advisable to secure the vote or consent of its stockholders required by the rules of the NYSE or applicable Laws to obtain such approvals.

(c)    Notwithstanding anything in this Agreement to the contrary, the Company may, in consultation with Parent, postpone or adjourn the Company Stockholders’ Meeting (i) to solicit additional proxies for the purpose of obtaining the Company Stockholder Approval, (ii) if there are insufficient shares of Company Common Stock and Company Preferred Stock present to constitute a quorum to conduct business at such meeting, (iii) to allow reasonable additional time for the filing and/or mailing of any supplemental or amended disclosure that the Company has determined 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 stockholders of the Company prior to the Company Stockholders’ Meeting or (iv) if the Company has delivered any notice contemplated by Section 5.4(e) and the time periods contemplated by Section 5.4(e) have not expired.

Section 5.6    Equity-Based Awards.

(a)    Each award of restricted share units that corresponds to Shares and vests solely based on the passage of time (each, a “Company RSU Award”), whether vested or unvested, that is outstanding immediately prior to the Effective Time, shall, as of the Effective Time, shall be assumed by Parent and converted into a restricted unit award with respect to

- 54 -

Common Units (each an “Assumed RSU Award”). Each Assumed RSU Award shall be converted into a restricted unit award to receive a number of Common Units equal to the product obtained by multiplying (x) the number of Shares subject to such Company RSU Award immediately prior to the Effective Time by (y) a ratio equal to (A)(1) the Per Share Cash Amount divided by (2) the closing price of one Common Unit on the NYSE on the day prior to the Closing Date plus (B) the Exchange Ratio (such ratio, the “Equity Exchange Ratio”), rounded up or down to the nearest whole Common Unit. Each Assumed RSU Award shall (i) otherwise be subject to the same terms and conditions (including as to vesting and issuance) as were applicable to the Company RSU Award immediately prior to the Effective Time and (ii) fully accelerate upon a termination without “cause,” for “good reason” or a result of the holder’s death or disability (as such terms are defined in Section 5.6(a) of the Company Disclosure Schedule).

(b)    Each award of performance share units that corresponds to Shares (each, a “Company PSU Award”), that is outstanding and vested as of the Effective Time, shall, as of the Effective Time, be cancelled in exchange for the payment of the Merger Consideration with respect to the number of Shares equal to the total number of Shares with respect to which such Company PSU Award has vested prior to the Effective Time. The Surviving Corporation shall issue to the holders of Company PSU Awards the Merger Consideration in respect of the applicable number of Shares described in the immediately preceding sentence, less such amounts as are required to be withheld or deducted under the Code or any provision of state, local or foreign Tax Law with respect to the making of such payment, within five business days following the Effective Time. Each Company PSU Award that is outstanding and unvested as of the Effective Time shall automatically, and without any required action of the holder thereof, be cancelled without consideration.

(c)    Each award of restricted Company Common Stock that is outstanding immediately prior to the Effective Time (the “Company Restricted Shares,” together with the Company RSU Awards and the Company PSU Awards, the “Company Equity Awards”) shall be assumed by Parent and converted into a restricted unit award with respect to Common Units (each an “Assumed Restricted Stock Award”). Each Assumed Restricted Stock Award shall be converted into a restricted unit award representing a contractual right upon vesting to receive a number of Common Units equal to the product obtained by multiplying (x) the number of Shares subject to such Assumed Restricted Stock Award immediately prior to the Effective Time by (y) the Equity Exchange Ratio, rounded up or down to the nearest whole Common Unit. Each Assumed Restricted Stock Award shall otherwise be subject to the same terms and conditions (including as to vesting and issuance) as were applicable to the Company Restricted Shares immediately prior to the Effective Time. Each Assumed Restricted Stock Award shall (i) otherwise be subject to the same terms and conditions (including as to vesting and issuance) as were applicable to the Company Restricted Shares immediately prior to the Effective Time, (ii) have distribution equivalent rights, and (iii) fully accelerate upon a termination without “cause,” for “good reason” or a result of the holder’s death or disability (as such terms are defined in Section 5.6(a) of the Company Disclosure Schedule).

(d)    Notwithstanding the foregoing, each Company Restricted Share and Company RSU Award that is outstanding immediately prior to the Effective Time that is held by a non-employee director of the Board of Directors (a “Director Restricted Share Award”) shall,

- 55 -

as of the Effective Time, become fully vested and shall be cancelled in exchange for the payment of the Merger Consideration with respect to the total number of Shares subject to such Director Restricted Share Award. The Surviving Corporation shall issue to the holders of Director Restricted Share Awards the Merger Consideration in respect of the applicable number of Shares described in the immediately preceding sentence, less such amounts as are required to be withheld or deducted under the Code or any provision of state, local or foreign Tax Law with respect to the making of such payment, within five (5) business days following the Effective Time.

(e)    Prior to the Effective Time, the Company shall take all actions (including obtaining any necessary determinations and/or resolutions of the Board of Directors of the Company or a duly authorized committee thereof, and, if appropriate, amending the terms of the ESPP) that may be necessary or required under the ESPP and applicable Laws to ensure that (i) no new offering period under the ESPP shall begin after September 30, 2019; (ii) with respect to the current offering period set to end on September 30, 2019 any remaining contributions held in the participant accounts under the ESPP after the purchase of shares of Company Common Stock at the end of such offering period shall be returned to the participant (without interest) after the last business day of the offering, (iii) the ESPP shall terminate in its entirety immediately prior to the Closing and no further rights shall be granted or exercised under the ESPP thereafter. Notwithstanding any restrictions on transfer of stock in the ESPP, all shares of Company Common Stock purchased under the ESPP shall be treated in accordance with Section 2.1(a).

(f)    The Company shall take any and all actions reasonably necessary to effectuate the transactions contemplated by this Section 5.6.

Section 5.7    Employee Matters.

(a)    Following the Effective Time and until the first anniversary of the Closing Date, Parent shall, or shall cause one of its Subsidiaries to, provide the individuals who are employed by the Company or any of its Subsidiaries immediately before the Effective Time (the “Current Employees”) and who continue employment during such time period with (i) annual base salary or wages (as applicable) that are no less favorable than the annual base salary or wages (as applicable) provided to such Current Employees immediately prior to the Effective Time, (ii) severance benefits that are no less favorable than the severance benefits in effect for such Current Employees as immediately prior to the Effective Time, as set forth on Section 5.7(a)(ii) of the Company Disclosure Schedule, and (iii) other compensation and employee benefits that are substantially comparable in the aggregate to either, at Parent’s election, (A) the other compensation and employee benefits provided to similarly situated employees of Parent and its Subsidiaries, or (B) the other compensation and employee benefits provided to such Current Employees immediately prior to the Effective Time (excluding equity compensation, defined benefit and supplemental pensions and retiree medical benefits).

(b)    For purposes of vesting, eligibility to participate and, solely for vacation and paid time off policies, severance plans and policies, and disability plans and policies, determining levels of benefits (but not, for the avoidance of doubt, for purposes of benefit accrual under any defined benefit pension plan) under the employee benefit plans of Parent and its Subsidiaries providing benefits to any Current Employees after the Effective Time (the “New

- 56 -

Plans”), each Current 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 Current Employee was entitled, before the Effective Time, to credit for such service under any similar Company Benefit Plan in which such Current Employee participated or was eligible to participate immediately prior to the Effective Time, provided 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. In addition, and without limiting the generality of the foregoing, (i) each Current 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 comparable to a Company Benefit Plan in which such Current Employee participated immediately before the Effective Time (such plans, collectively, the “Old Plans”), (ii) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Current 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 employee and his or her covered dependents, unless and to the extent the individual, immediately prior to entry in the New Plans, was subject to the same such conditions under the comparable Old Plans, and (iii) credit amounts paid under any Old Plan providing medical, dental, pharmaceutical and/or vision benefits under any corresponding New Plan for purposes of applying deductibles, co-payments and out-of-pocket maximums as though such amounts had been paid in accordance with the terms and conditions of the New Plan with respect to the plan year in which the Effective Time occurs. For purposes of this Agreement, “Benefit Plans” means any (i) “employee benefit plan” (within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)), (ii) bonus, incentive or deferred compensation or equity or equity-based compensation plan, program, policy or arrangement, including employer stock and incentive plans, (iii) severance, change in control, employment, consulting, retirement, retention or termination plan, program, agreement, policy or arrangement or (iv) other compensation or benefit plan, program, agreement, policy, practice, contract, arrangement or other obligation, whether or not in writing and whether or not subject to ERISA, including all bonus, cash or equity-based incentive, deferred compensation, stock purchase, health, medical, dental, disability, accident, life insurance, or vacation, paid time off, perquisite, fringe benefit, severance, change of control, retention, employment, separation, retirement, pension, or savings, plans, programs, policies, agreements or arrangements.

(c)    Each Current Employee who as of immediately prior to the Effective Time is eligible for an annual bonus under a Company Benefit Plan for 2019, is employed by the Surviving Corporation or its affiliates on December 31, 2019 and is not terminated for cause (as defined in Section 5.7(c) of the Company Disclosure Schedule) shall receive an annual bonus for 2019 (to the extent such bonus is not otherwise paid prior to the Effective Time) in an amount equal to not less than 100% of the target amount of such bonus (the “2019 Annual Bonuses”); provided that if such Current Employee is terminated without cause (as such term is defined in Section 5.7(c) of the Company Disclosure Schedule) prior to December 31, 2019, such Current Employee shall remain entitled to receive a pro-rated portion of his or her 2019 Annual Bonus based on the number of days such Current Employee was employed during the 2019 calendar year. The 2019 Annual Bonuses shall be payable no later than date annual bonuses are paid to Parent’s other similarly situated employees, but in any event before March 15, 2020.

- 57 -

(d)    Parent hereby acknowledges that a “change of control” (or similar phrase) within the meaning of the Company Benefit Plans will occur at or prior to the Effective Time, as applicable.

(e)    If requested by Parent, subject to the terms of any such Company Benefit Plan and applicable Law, the Company shall both (i) terminate any Company Benefit Plan qualified under Section 401(a) of the Code and containing a Code Section 401(k) cash or deferred arrangement (a “Company 401(k) Plan”) and (ii) fully vest each Current Employee in his or her account balance in such Company 401(k) Plan, in each case, effective at least one day prior to the Closing Date (the “ERISA Effective Date”). Prior to the ERISA Effective Date, the Company shall provide Parent with executed resolutions of its or, as applicable, its Subsidiary’s Board of Directors authorizing such termination and amending any such Company 401(k) Plan commensurate with its termination to the extent necessary to comply with all applicable Laws. The Company shall also take and/or cause its Subsidiaries to take such other actions in furtherance of the termination of each Company 401(k) Plan as Parent may reasonably require, including such actions as Parent may require prior to the Effective Time to support Parent obtaining a determination letter with respect to the termination of each Company 401(k) Plan following the ERISA Effective Date.

(f)    In the event of the termination, pursuant to Section 5.7(d), of any Company 401(k) Plan (each such terminated Company 401(k) Plan, a “Terminated Company 401(k) Plan”), Parent or its applicable Subsidiary shall cause a defined contribution plan that is qualified under Section 401(a) of the Code, that includes a cash or deferred arrangement within the meaning of Section 401(k) of the Code and that is established or maintained by Parent or its applicable Subsidiary (a “Parent 401(k) Plan”) to immediately accept eligible rollover distributions (as defined in Section 402(c)(4) of the Code) from current and former employees of the Company and its Subsidiaries with respect to such individuals’ account balances (including loans) under such Terminated Company 401(k) Plan, if elected by any such individuals. The rollovers described herein shall comply with applicable Law, and Parent and its Subsidiaries shall make all filings and take any actions required of such party under applicable Law in connection therewith. Current and former employees of the Company and its Subsidiaries who are participants in a Terminated Company 401(k) Plan immediately prior to the Effective Time shall be eligible immediately as of the Effective Time to participate in a Parent 401(k) Plan.

(g)    Prior to the Closing Date, the Company shall take all actions necessary to amend the Key Employee Severance Plan and the Severance Pay Plan as set forth on Section 5.7(g) of the Company Disclosure Schedule.

(h)    Nothing in this Section 5.7 shall be construed as an amendment of, or undertaking to amend, any Benefit Plan or to prevent the amendment or termination of any Benefit Plan in accordance with its terms. Nothing in this Section 5.7 shall limit the right of Parent, the Surviving Corporation or any of their Subsidiaries to terminate the employment of any Current Employee at any time, subject to any rights to severance or other separation benefits accrued as of the applicable termination date under a Company Benefit Plan. Without limiting the generality of Section 8.13, the provisions of this Section 5.7 are solely for the benefit of the parties to this Agreement, and no current or former director, officer, employee, other service provider or independent contractor or any other person shall be a third-party beneficiary of this

- 58 -

Agreement, and nothing herein shall be construed as an amendment to any Company Benefit Plan or other compensation or benefit plan or arrangement (including any Benefit Plan of Parent or its Subsidiaries) for any purpose.

Section 5.8    Regulatory Approvals; Efforts.

(a)    Subject to the terms and conditions set forth in this Agreement, each of the parties hereto shall use (and shall cause its Subsidiaries and Affiliates to use) its reasonable best efforts to take, or cause to be taken, promptly all actions, and to do, or cause to be done, promptly and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable under applicable Laws to consummate and make effective the Merger and the other transactions contemplated by this Agreement, including using reasonable best efforts to: (i) obtain all necessary actions or nonactions, waivers, clearances, consents and approvals, including the Company Approvals and the Parent Approvals, from Governmental Entities and make all necessary registrations, notifications and filings and take other steps as may be necessary to obtain an action or nonaction, waiver, clearance, consent or approval from, or to avoid an action or proceeding by, any Governmental Entity, in each case as promptly as practicable, (ii) obtain all necessary consents, approvals or waivers from third parties other than any Governmental Entity, in each case as promptly as reasonably practicable, (iii) defend any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated by this Agreement, including seeking to have any stay or temporary restraining order entered by any Governmental Entity vacated or reversed, and (iv) execute and deliver any additional instruments necessary to consummate the transactions contemplated by this Agreement. In the event that any litigation, administrative or judicial action or other proceeding is commenced challenging the Merger or any of the proposed transactions, each of the Company, Parent, and Merger Sub shall cooperate with each other and use its respective reasonable best efforts to contest and resist any such litigation, action or proceeding and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the transactions contemplated by this Agreement.

For a period of six years from the Effective Time, Parent and the Surviving Corporation shall maintain in effect any and all exculpation, indemnification and advancement of expenses provisions of the Company’s and any of its Subsidiaries’ certificates of incorporation and bylaws or similar organizational documents in effect immediately prior to the Effective Time or in any indemnification agreements of the Company or its Subsidiaries with any of their respective current or former directors, officers or employees in effect immediately prior to the Effective Time, and shall not amend, repeal or otherwise modify any such provisions or the exculpation, indemnification or advancement of expenses provisions of the Surviving Corporation’s certificate of incorporation and bylaws in any manner that would adversely affect the rights thereunder of any individuals who immediately before the Effective Time were current or former directors, officers or employees of the Company or any of its Subsidiaries; provided, however, that all rights to indemnification in respect of any Action pending or asserted or any

- 61 -

claim made within such period shall continue until the disposition of such Action or resolution of such claim. From and after the Effective Time, Parent shall assume, be jointly and severally liable for, and honor, guaranty and stand surety for, and shall cause the Surviving Corporation and its Subsidiaries to honor and perform, in accordance with their respective terms, each of the covenants contained in this Section 5.11 without limit as to time.

In the event of any such Action, the Surviving Corporation shall cooperate with the Indemnified Party in the defense of any such Action.

(c)    For a period of six years from the Effective Time, Parent shall cause to be maintained in effect the coverage provided by the policies of directors’ and officers’ liability insurance and fiduciary liability insurance in effect as of the date hereof by the Company and its Subsidiaries with respect to matters existing or arising on or before the Effective Time; provided, however, that Parent shall not be required to pay annual premiums in excess of 300% of the last annual premium paid by the Company prior to the date hereof in respect of the coverages (the “Maximum Amount”) required to be obtained pursuant hereto, but in such case shall purchase as much coverage as reasonably practicable for such amount. If the Company in its sole discretion elects, then the Company may, prior to the Effective Time, purchase a “tail policy” with respect to acts or omissions occurring or alleged to have occurred prior to the Effective Time that were committed or alleged to have been committed by such Indemnified Parties in their capacity as such; provided that in no event shall the cost of such policy exceed six (6) times the Maximum Amount and, if such a “tail policy” is purchased, Parent shall have no further obligations under this Section 5.11(c). If a “tail policy” is purchased, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, maintain such policies in full force and effect, and continue to honor the obligations thereunder.

(d)    Parent shall pay all reasonable expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in enforcing the indemnity and other obligations provided in this Section 5.11.

(f)    In the event Parent, the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then, and in either such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations of such party set forth in this Section 5.11. Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or any of its Subsidiaries or their respective officers, directors and employees, it being understood and agreed that the indemnification provided for in this Section 5.11 is not prior to, or in substitution for, any such claims under any such policies.

(g)    The obligations of Parent and the Surviving Corporation under this Section 5.11 shall not be terminated, amended or modified in any manner so as to adversely affect any Indemnified Party (including their successors, heirs and legal representatives) to whom this Section 5.11 applies without the consent of such Indemnified Party. It is expressly agreed that, notwithstanding any other provision of this Agreement that may be to the contrary, (i) the Indemnified Parties to whom this Section 5.11 applies shall be third-party beneficiaries of this Section 5.11, and (ii) this Section 5.11 shall survive consummation of the Merger and shall be enforceable by such Indemnified Parties and their respective successors, heirs and legal representatives against Parent and the Surviving Corporation and their respective successors and assigns.

Section 5.12    Control of Operations. Without in any way limiting any party’s rights or obligations under this Agreement, the parties understand and agree that (a) nothing contained in this Agreement shall give Parent or the Company, directly or indirectly, the right to control or direct the other party’s operations prior to the Effective Time and (b) prior to the Effective Time, each of the Company and Parent shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its operations.

Section 5.14    Intended Tax Treatment. Parent and the Company each acknowledges and agrees that, for U.S. federal income and applicable state and local tax purposes and pursuant to the Merger, each holder of Company Common Stock will be deemed to contribute its Company Common Stock to Parent in exchange for Merger Consideration and the deemed assumption of each such holder’s share of the liabilities of Parent pursuant to Section 752 of the Code. Parent and Company each acknowledges and agrees that, for U.S. federal income and applicable state and local tax purposes, such deemed transaction is intended to qualify for non-recognition of gain or loss pursuant to Section 721 of the Code but will be characterized as a disguised sale transaction described in section 707(a)(2)(B) of the Code with respect to any amounts treated as a transfer of consideration pursuant to Treasury Regulation Section 1.707-3(a)(1) (such treatment, the “Intended Tax Treatment”). Unless required to do so as a result of a “determination” as defined in Section 1313 of the Code, each of Parent and Company agrees not to make any tax filings or otherwise take any position inconsistent with the Intended Tax Treatment and to cooperate with the other party to make any filings, statements, or reports required to effect, disclose or report the Intended Tax Treatment.

Without limiting the generality of the foregoing, the Company shall, and shall cause its Subsidiaries and their respective Representatives to, upon reasonable request, (i) furnish the report of the Company’s auditor on the three most recently available audited consolidated financial statements of the Company and its Subsidiaries and use its reasonable best efforts to obtain the consent of such auditor to the use of such reports, including in documents filed with the SEC under the Securities Act, in accordance with normal custom and practice and use reasonable best efforts to cause such auditor to provide customary comfort letters to the arrangers, underwriters, initial purchasers or placement agents, as applicable, in connection with any such financing; (ii) furnish any additional financial statements, schedules, business or other financial data relating to the Company and its Subsidiaries as may be reasonably necessary to consummate any such financing; it being understood that Parent shall be responsible for the preparation of any pro forma financial information or pro forma financial statements required pursuant to the Securities Act or as may be customary in connection with any such financing; (iii) provide direct contact between (x) senior management and advisors, including auditors, of the Company and (y) the proposed arrangers, lenders, underwriters, initial purchasers or placement agents, as applicable, and/or Parent’s auditors, as applicable, in connection with any

- 64 -

such financing, at reasonable times and upon reasonable advance notice; (iv) make available the employees and advisors of the Company and its Subsidiaries to provide reasonable assistance with Parent’s or its Subsidiaries’ preparation of business projections, financing documents and offer materials; (v) obtain the cooperation and assistance of counsel to the Company and its Subsidiaries in providing customary legal opinions and other services; (vi) assist in the preparation of (but not entering into or executing) documents, opinions and certificates, and other agreements (including indentures or supplemental indentures) and take other actions that are or may be customary in connection with any such financing or necessary or desirable to permit Parent or its Subsidiaries to fulfill conditions or obligations under the financing documents, provided that such agreements shall be conditioned upon, and shall not take effect until, the Effective Time; (vii) assist in the preparation of one or more confidential information memoranda, prospectuses, offering memoranda and other marketing and syndication materials reasonably requested by Parent; (viii) permit Parent or its Subsidiaries’ reasonable use of the Company’s and its Subsidiaries’ logos for syndication and underwriting, as applicable, in connection with any such financing (subject to advance review of and consultation with respect to such use), (ix) participate in a reasonable number of meetings and presentations with arrangers and prospective lenders and investors, as applicable (including the participation in such meetings of the Company’s senior management), in each case at times and locations to be mutually agreed, and (x) use commercially reasonable efforts to assist in procuring any necessary rating agency ratings or approvals.

(b)    Notwithstanding anything in this Section 5.16 to the contrary, in fulfilling its obligations pursuant to this Section 5.16, (i) none of the Company, its Subsidiaries or its Representatives shall be required to (x) pay any commitment or other fee, provide any security or incur any other liability in connection with any financing prior to the Effective Time, (y) enter into any definitive agreement the effectiveness of which is not conditioned upon the Closing; or (z) give any indemnities that are effective prior to the Effective Time, (ii) any requested cooperation shall not unreasonably interfere with the ongoing operations of the Company and its Subsidiaries, and (iii) Parent shall, promptly upon request by the Company, reimburse the Company for all reasonable and documented out-of-pocket costs incurred by the Company or any of its Subsidiaries in connection with such cooperation. Parent shall indemnify and hold harmless the Company and its Subsidiaries from and against any and all losses or damages actually suffered or incurred by them directly in connection with the arrangement of any such financing (other than to the extent related to information provided by the Company, its Subsidiaries or their respective Representatives). In addition, no action, liability or obligation of the Company, any of its Subsidiaries or any of their respective Representatives pursuant to any certificate, agreement, arrangement, document or instrument relating to any financing will be effective until the Effective Time, and neither the Company nor any of its Subsidiaries will be required to take any action pursuant to any certificate, agreement, arrangement, document or instrument that is not contingent on the occurrence of the Closing or that must be effective prior to the Effective Time. Nothing in this Section 5.16 will require the Company, its Subsidiaries or their respective Representatives to execute, deliver or enter into, or perform any agreement, document or instrument, including any definitive financing document, with respect to any financing or adopt resolutions approving the agreements, documents and/or instruments pursuant to which any financing is obtained or pledge any collateral with respect to any financing prior to the Closing. Nothing in this Section 5.16 shall require (A) any officer or Representative of the Company or any of its Subsidiaries to deliver any certificate or take any other action under this

- 65 -

Section 5.16 that could reasonably be expected to result in personal liability to such officer or Representative; or (B) the Board of Directors of the Company to approve any financing or contracts related thereto prior to the Effective Time (it being understood and agreed that all such certificates, opinions or resolutions shall be delivered by any officer or board members of the Surviving Corporation immediately after the Effective Time). The Company and its Subsidiaries and Representatives shall not be required to deliver any legal opinions or solvency certificates.

(c)    At the request of Parent, the Company shall deliver to Parent at least two business days prior to the Closing Date payoff letters from any third-party lenders (or agents therefor), trustees, or other holders of indebtedness of the Company or its Subsidiaries (or representatives therefor), as applicable, in the customary forms of such lenders, trustees or other holder of indebtedness or otherwise in form reasonably satisfactory to Parent, with respect to the indebtedness or obligations of the Company and its Subsidiaries set forth in Section 5.16(c) of the Company Disclosure Schedule. At the sole cost and expense of Parent, the Company shall reasonably cooperate with Parent in replacing any letters of credit issued pursuant to the facilities evidencing the above referenced indebtedness or obligations.

(d)    The Company shall, at the request of Parent, (i) call for prepayment or redemption, or prepay or redeem, (ii) attempt to renegotiate the terms of, (iii) commence an offer to purchase and/or consent solicitation or (iv) satisfy and discharge or defease any then-existing indebtedness for borrowed money of the Company or any of its Subsidiaries; provided, however, that the Company and its Subsidiaries shall not be obligated to make or cause to become effective any such action (nor shall the Company or any of its Subsidiaries be required to incur any cost or liability in respect thereof) prior to the Effective Time. For the avoidance of doubt, any redemption, prepayment or other payment made to satisfy and discharge or defease such portion of the Company Indebtedness prior to or at the Closing shall be the obligation of Parent. Parent shall prepare all necessary and appropriate documentation in connection with any action described above, and provide the Company with a reasonable opportunity to comment on such documents. Parent and the Company shall, and shall cause their respective Subsidiaries and Representatives to, reasonably cooperate with each other in the preparation of such documents.

Section 5.17    Tulsa Office. At the Effective Time and for no less than two (2) years thereafter, Parent and the Surviving Corporation shall maintain an office in the Tulsa, Oklahoma metropolitan area.

ARTICLE VII.

TERMINATION

Section 7.1    Termination or Abandonment. Notwithstanding anything in this Agreement to the contrary, this Agreement may be terminated and abandoned at any time prior to the Effective Time, whether before or after Company Stockholder Approval has been obtained:

(a)    by the mutual written consent of the Company and Parent;

- 68 -

Section 6.1(c), shall have been satisfied or shall be capable of being satisfied at such time, the End Date shall automatically be extended to September 30, 2020, which date shall thereafter be deemed to be the End Date; provided, further, that the right to terminate this Agreement pursuant to this Section 7.1(b) shall not be available to a party if the failure of the Closing to occur by such date shall be due to the material breach by such party of any representation, warranty, covenant or other agreement of such party set forth in this Agreement;

(c)    by either the Company or Parent, if an injunction or other Law shall have been entered, enacted or become effective permanently restraining, enjoining or otherwise prohibiting the consummation of the Merger and such injunction or other Law has become final and nonappealable; provided, however, that the right to terminate this Agreement under this Section 7.1(c) shall not be available to a party if such injunction was due to the failure of such party to perform any of its obligations under this Agreement;

(e)    by the Company, if Parent or Merger Sub shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (i) if it occurred or was continuing to occur on the Closing Date, would result in a failure of a condition set forth in Section 6.2(a) or Section 6.2(b) and (ii) by its nature, cannot be cured prior to the End Date or, if such breach or failure is capable of being cured by the End Date, Parent does not diligently attempt or ceases to diligently attempt to cure such breach or failure after receiving written notice from the Company describing such breach or failure in reasonable detail (provided that the Company is not then in material breach of any representation, warranty, covenant or other agreement contained herein);

(f)    by Parent, if the Company shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (i) if it occurred or was continuing to occur on the Closing Date, would result in a failure of a condition set forth in Section 6.3(a) or Section 6.3(b) and (ii) by its nature, cannot be cured prior to the End Date or, if such breach or failure is capable of being cured by the End Date, the Company does not diligently attempt, or ceases to diligently attempt, to cure such breach or failure in such a manner that would make it reasonably likely that such breach or failure will be cured prior to the End Date, in each case after receiving written notice from Parent describing such breach or failure in reasonable detail (provided that Parent is not then in material breach of any representation, warranty, covenant or other agreement contained herein);

- 69 -

(c)    If this Agreement is terminated by Parent pursuant to (i) Section 7.1(g)(i) [Change of Recommendation] or (ii) Section 7.1(f) [Breach of Representation or Failure to Perform Covenant], so long as the breach giving rise to the right to terminate this Agreement pursuant to Section 7.1(f) was the Company’s failure to call and hold a Company Stockholders’ Meeting in violation of its obligations under Section 5.5(b), and, in each of cases (i) or (ii), prior to such termination and after the date of this Agreement, any person (other than Parent, Merger Sub or any of their respective affiliates) shall have made an Acquisition Proposal, which shall have been publicly announced or disclosed or otherwise communicated to the Board of Directors of the Company and not have been withdrawn prior to such termination, then the Company shall pay to Parent, within three (3) business days after the date of termination, the Breakup Fee, by wire transfer of same day federal funds to the account specified by Parent.

(e)    If this Agreement is terminated by Parent pursuant to Section 7.1(g)(i) [Change of Recommendation] in circumstances where the Breakup Fee is not payable pursuant to Section 7.3(c), then the Company shall pay to Parent the Parent Expenses, by wire transfer of same day federal funds to the account specified by Parent within three (3) business days following termination of this Agreement, and, if within twelve months after such termination of this Agreement, the Company shall have consummated, or shall have entered into an agreement to consummate (which may be consummated after such twelve-month period), an Acquisition Transaction, then the Company shall pay to Parent an amount equal to the Breakup Fee minus the Parent Expenses previously paid or reimbursed by the Company, by wire transfer of same day federal funds to the account specified by Parent, on the earlier of the public announcement of the Company’s entry into such agreement or the consummation of any such Acquisition Transaction.

(f)    Solely for purposes of this Section 7.3, “Acquisition Transaction” shall have the meaning ascribed thereto in Section 5.4, except that all references to twenty-five percent (25%) shall be changed to seventy-five percent (75%).

- 71 -

nothing herein shall release any party from liability arising out of or the result of fraud. The parties acknowledge and agree that in no event shall the Company be required to pay the Breakup Fee, as applicable, on more than one occasion. In addition, the parties acknowledge that the agreements contained in this Section 7.3 are an integral part of the transactions contemplated by this Agreement and are not a penalty, and that, without these agreements, neither party would enter into this Agreement. If the Company fails to pay promptly the amounts due pursuant to this Section 7.3, the Company will also pay to Parent interest on the unpaid amount under this Section 7.3, accruing from its due date, at an interest rate per annum equal to two percentage points in excess of the prime commercial lending rate quoted by The Wall Street Journal and the reasonable out-of-pocket expenses (including legal fees) in connection with any action taken to collect payment. Any change in the interest rate hereunder resulting from a change in such prime rate will be effective at the beginning of the date of such change in such prime rate.

EX-99.1

Exhibit 99.1

SEMGROUP TO BE ACQUIRED BY ENERGY TRANSFER IN $5 BILLION TRANSACTION

SemGroup to merge with one of the largest, diversified midstream energy companies in North America

Benefits of scale will strengthen and accelerate growth opportunities for SemGroup assets and improve access to capital markets

SemGroup shareholders to benefit from significant, immediate premium and future upside of combined company

Tulsa, Okla. – September 16, 2019 – SemGroup^® Corporation (NYSE: SEMG) today announced it has entered into a definitive merger agreement whereby SemGroup will be acquired by Energy Transfer LP (NYSE: ET) (“ET” or “Energy Transfer”) in a unit and cash transaction valued at approximately $5.1 billion, including the assumption of debt and other liabilities.

Under the terms of the agreement, which has been unanimously approved by the Boards of Directors of both companies, SemGroup shareholders will receive $6.80 per share in cash and 0.7275 of an ET common unit for each SemGroup share, or approximately 40% cash and 60% equity. The equity consideration received is expected to be treated as a tax-free transaction. The transaction values SemGroup at $17.00 per share, and represents a 65% premium to SemGroup’s closing share price of $10.28 on September 13, 2019, and an 87% premium to SemGroup’s 20 day volume weighted average price (VWAP) as of the same date. Upon closing, SemGroup shareholders are expected to own approximately 2.2% of ET’s outstanding common units.

SemGroup Chief Executive Officer, Carlin Conner, said, “This strategically and financially compelling combination will result in SemGroup joining one of the largest midstream energy companies in the country, with a strong footprint in all major U.S. production basins. The combined entity’s size, scale and financial profile will ensure that SemGroup’s assets, including our Gulf Coast terminal, mid-continent footprint and our Canadian joint venture SemCAMS Midstream, benefit from significant growth well into the future. We look forward to leveraging the increased pipeline connectivity and expanded terminalling infrastructure that the combined entity provides.

Conner continued, “SemGroup has been exploring a range of strategic alternatives aimed at increasing shareholder value, and determined that this combination with ET is in the best interests of shareholders — providing immediate value, a significant premium, and opportunity to participate in the future upside of the combined business. Our transaction with ET underscores the strength of SemGroup’s assets, and is a testament to our employees’ dedication, hard work and focus on providing safe, efficient and reliable service while creating an asset portfolio that is highly desired.”

The transaction is expected to close by late 2019 or early 2020, subject to obtaining regulatory approvals, SemGroup shareholder approval and other customary closing conditions.

Exhibit 99.4

Dear Team,

This morning we announced that SemGroup has entered into a definitive merger agreement with Energy Transfer. This strategic transaction will further strengthen and accelerate growth for our assets, while creating significant value for our shareholders. A link to the press release we issued this morning can be found here: [LINK].

The merger will result in SemGroup combining with one of the largest diversified midstream energy companies in North America, with a strategic footprint in all major U.S. production basins. The combined entity’s size, scale and financial capacity will strengthen and accelerate the growth opportunities for our U.S. businesses and our SemCAMS Midstream JV in Canada well into the future.

The decision to enter into this merger came following an in-depth assessment of numerous strategic options. After significant review and contemplation, we concluded that it was in the best interests of our shareholders to accept this proposal. The last several years have been difficult for the energy industry, but together we have persevered through the ups and downs while building a highly valued company with desired assets. Because of those efforts, Energy Transfer identified SemGroup as a company that they wanted as part of their organization and was willing to pay a premium to secure the merger.

I know that you will have many questions about the merger and what it will mean to you personally. We will be holding an all-employee meeting this morning at 10:00 AM CT to discuss the transaction further. Our commitment to you is to keep you informed throughout this process and to do our best to answer your questions as quickly as possible.

We expect this transaction to close in the first quarter of 2020, subject to SemGroup shareholder approval and obtaining certain other customary regulatory approvals. Until it closes it will be business as usual at SemGroup. We will continue to operate as separate companies, and it is critical that we all stay focused on our day-to-day responsibilities and continue to deliver the safe and reliable service our customers have come to expect.

I would encourage you to review the press release we posted on semgroup.com and Inside SemGroup, as well as the Employee FAQ on Inside SemGroup. For any other questions, please reach out to your team leader and, as always, you can submit questions anonymously on Inside SemGroup.

Today’s announcement wouldn’t be possible without your continued dedication, hard work and focus on providing safe, efficient and reliable service to our customers. Thank you. I look forward to speaking with you later this morning and in the coming weeks.

Exhibit 99.6

Employee FAQ

1. Who is Energy Transfer?

• Since being founded in 1996, Energy Transfer has grown to be one of the largest diversified midstream energy companies in the United States, with a strategic footprint in all the major U.S. production basins. They operate more than 86,000 miles of pipelines traversing 38 states and are responsible for moving around 30% of our nation’s natural gas and crude oil on their pipelines. They employ over 10,000 people and have a culture founded on integrity, community, excellence and responsibility.

2. What is the reason for doing this transaction?

• Recent market conditions have been challenging for energy businesses, and as a result, SemGroup’s board has been exploring opportunities that will further strengthen and accelerate growth for our assets, while creating significant value for our shareholders.

• The merger will result in SemGroup combining with one of the largest diversified midstream energy companies in North America, with a strategic footprint in all the major U.S. production basins.

• The combined entity’s size, scale and financial capacity will strengthen and accelerate the growth opportunities for our U.S. businesses and our SemCAMS Midstream JV in Canada well into the future.

3. Did the board look at other options?

• The decision to enter into this merger came following an in-depth assessment of numerous strategic options. After significant review and contemplation, the board of directors unanimously determined that the combination with Energy Transfer is in the best interests of our shareholders.

4. What does this news mean for me? Is my job safe?

• In the near term, there is no change at all – it is business as usual.

• We are committed to communicating openly and honestly throughout this process.

• In the meantime, it is critical that we all stay focused on our day-to-day responsibilities and continue to deliver the safe and reliable service our customers have come to expect.

5. Why couldn’t we continue to do what we were doing?

• Recent market conditions have been challenging for energy businesses. A lack of capital inflows into our markets has made it difficult to raise money to fund future growth through ordinary capital markets.

• We, as a company, have persevered through the ups and downs while building a highly valued business with desired assets. Because of those efforts, Energy Transfer has identified SemGroup as a company that they wanted as part of their organization and was willing to pay a premium to secure the merger.

6. Do you anticipate any reductions in staff?

• It’s too soon to know what this will mean for each of our employees in the long term, and it would be inappropriate to speculate.

• In the near term, there is no change at all – it is business as usual.

• We expect that Energy Transfer will outline specific integration plans following closing, which is expected in the first quarter 2020.

7. When will I know if I have a position at Energy Transfer?

• We don’t have all the answers today, but we’ll tell you what we do know, and are committed to keeping you informed along the way as decisions are made.

• It’s important to remember that nothing changes immediately. The transaction is expected to close in the first quarter 2020. Until then, it is business as usual at SemGroup and we will continue to operate as a separate company.

8. How has the current environment in energy markets impacted your decision to sell the business?

• It’s no secret that the last several years have been difficult for the energy industry. A lack of capital inflows into our markets has made it difficult to raise money to fund future growth through ordinary capital markets.

• SemGroup responded to these challenges by executing on joint ventures and other projects that capitalized on the strength of our premium asset portfolio.

• We expect that energy markets will continue to be volatile in the medium term, so the merger with Energy Transfer is in the best interests of shareholders and will help ensure our assets can continue to grow well into the future.

9. Will SemGroup operate as a separate company or will the assets and operations be fully integrated with Energy Transfer’s existing portfolio?

• Energy Transfer has one of the largest and most diversified energy portfolios in North America, with more than 86,000 miles of pipelines traversing 38 states.

• We expect that Energy Transfer will outline specific integration plans following closing, and until then, it’s business as usual and we will continue to operate as separate companies.

• Energy Transfer has indicated that following the closing SEMG assets will be contributed to Energy Transfer Operating (ETO).

10. What will happen to SemGroup’s Tulsa HQ?

• First, it is important to say that nothing at all is changing in the near term – it is business as usual at SemGroup and both businesses will continue to operate as separate entities until the close of the transaction.

• The Merger Agreement stipulates that Energy Transfer will maintain an office in Tulsa for no less than two years.

11. What will happen to my pay and benefits?

• Both businesses will continue to operate as separate entities until the close of the transaction so there will be no immediate changes.

• There will be no change to your annual base pay during the first year. The integration team will review other compensation and benefits plans to provide a package substantially comparable in the aggregate to either the employee’s current benefits program or ET’s benefits plan.

12. Do SemGroup and Energy Transfer share similar cultures?

• While SemGroup and Energy Transfer may differ in size, they are closely aligned on company values, in particular a commitment to safety, quality, integrity and community.

• Both companies have talented and highly engaged workforces that support well-balanced and complementary portfolios of midstream assets.

13. Should I reach out to employees at Energy Transfer?

• No. Until the transaction closes, the two businesses will continue to operate as separate entities.

• It is critical that we all stay focused on our day-to-day responsibilities and continue to deliver the safe and reliable service our customers have come to expect.

14. What should I say to customers or third parties who ask me about this news?

• As with any transaction involving two public companies, it is highly sensitive and best not to be drawn in to a conversation.

• Please direct all customer inquiries to Shaun Revere at srevere@semgroup.com

• Please direct all media inquiries to Tom Droege at tdroege@semgroup.com

• Please direct all investor inquiries to Kevin Greenwell at kgreenwell@semgroup.com

15. Who should I speak to if I have questions?

• We encourage you to talk with your department leader or Kay Kittleman in HR at kkittleman@semgroup.com.
