Subject to Section 3.1(c), Section 3.3(d) and Section 3.5, each Common Unit (other than any Common Units owned by Parent and its Subsidiaries immediately prior to the Effective Time) issued and outstanding as of immediately prior to the Effective Time (each, a “Public Common Unit”) shall be converted into, and shall thereafter represent only, the right to receive 0.113 of a Parent Share (the “Merger Consideration” and such ratio, the “Exchange Ratio”), subject to adjustment in accordance with Section 3.5, which Parent Shares will be duly authorized, validly issued, fully paid and non-assessable in accordance with applicable Laws.

(b) Equity of Merger Sub.

(c) Treatment of Partnership Interests Owned by the Partnership, Parent or their Subsidiaries.

(i) Any Partnership Interests that are owned immediately prior to the Effective Time by the Partnership or any Subsidiary of the Partnership shall be automatically canceled at the Effective Time and shall cease to exist. No consideration will be delivered in exchange for such canceled Partnership Interests.

(ii) Any Partnership Interests that are owned immediately prior to the Effective Time by Parent or any Subsidiary of Parent (excluding the General Partner Interest (discussed in clause (iii) below)), shall not be canceled, shall not be converted into the Merger Consideration and shall remain outstanding as Partnership Interests in the Surviving Entity.

Section 3.2 Rights as Partnership Unitholders; Common Unit Transfers. All Public Common Units converted into the right to receive the Merger Consideration pursuant to Section 3.1(a) will cease to be Outstanding (as such term is defined in the Partnership Agreement) and will automatically be canceled and will cease to exist when converted into the right to receive the Merger Consideration as a result of and pursuant to the Merger. At the Effective Time, each holder of a certificate that immediately prior to the Effective Time represented Public Common Units (a “Certificate”) and each holder of non-certificated Public Common Units represented by book-entry immediately prior to the Effective Time (“Book-Entry Units”) will cease to have any rights with respect thereto or thereunder, except the right to receive (a) the Merger Consideration, (b) any dividend or distribution in accordance with Section 3.3(c), in each case to be issued or paid, without interest, in consideration therefor upon surrender of such Certificate or Book-Entry Units in accordance with Section 3.3 and (c) any distribution in respect of the Common Units with a record date occurring prior to the Effective Time that may have been declared by the Partnership on the Common Units in accordance with the terms of this Agreement and the Partnership Agreement and which remains unpaid at the Effective Time. At the Effective Time, the transfer books of the Partnership will be closed immediately and there will be no further registration of transfers on the transfer books of the Partnership with respect to the Public Common Units.

Section 3.3 Exchange of Certificates and Book-Entry Units.

(a) Exchange Agent. Prior to the Effective Time, Parent will appoint Computershare Trust Company, N.A. to act as exchange and payment agent hereunder for the purpose of exchanging Public Common Units for the Merger Consideration as required by this Article III (the “Exchange Agent”). Promptly after the Effective Time, but on the Closing Date, Parent will deposit, or cause to be deposited, with the Exchange Agent for the benefit of the holders of the applicable Public Common Units, for exchange in accordance with this Article III, through the Exchange Agent, Parent Shares as required by this Article III in exchange for Public Common Units. Parent agrees to make available, or cause to be made available, to the Exchange Agent, from time to time as needed, cash sufficient to pay any dividends or other distributions pursuant to Section 3.3(c) or cash in lieu of fractional Parent Shares pursuant to Section 3.3(d), in each case, without interest. Any dividends with respect to Parent Shares pursuant to Section 3.3(c), Parent Shares for payment of the Merger Consideration deposited with the Exchange Agent and cash in lieu of fractional Parent Shares pursuant to Section 3.3(d) are hereinafter referred to as the “Exchange Fund.” The Exchange Agent will, pursuant to irrevocable instructions from Parent and the Partnership, deliver the Merger Consideration contemplated to be issued or paid pursuant to this Agreement out of the Exchange Fund. Except as contemplated by Section 3.3(b) and Section 3.3(c), the Exchange Fund will not be used for any other purpose.

(b) Exchange Procedures. Promptly after the Effective Time, Parent will instruct the Exchange Agent to mail to each record holder of Public Common Units as of the Effective Time (i) a letter of transmittal (specifying that in respect of certificated Public Common Units, delivery will be effected, and risk of loss and title to the Certificates will pass, only upon proper delivery of the Certificates to the Exchange Agent, and which will be in customary form and agreed to by Parent and the Partnership prior to the Effective Time) and (ii) instructions (in customary form and agreed to by Parent and the Partnership prior to the Effective Time) for use in effecting the surrender of the Certificates or Book-Entry Units in exchange for the Merger Consideration payable in respect of Public Common Units represented by such Certificates or

16

Book-Entry Units, as applicable. Promptly after the Effective Time, upon surrender of Certificates, if any, for cancellation to the Exchange Agent together with such letters of transmittal, properly completed and duly executed, and such other documents (including in respect of Book-Entry Units) as may be reasonably required pursuant to such instructions, each holder who held Public Common Units immediately prior to the Effective Time will be entitled to receive upon surrender of the Certificates or Book-Entry Units therefor (subject to any applicable withholding Tax) (A) Parent Shares representing, in the aggregate, the whole number of Parent Shares that such holder has the right to receive pursuant to this Article III (after taking into account all Public Common Units then held by such holder) and (B) a check in an amount equal to the aggregate amount of cash that such holder has the right to receive pursuant to this Article III, including dividends or other distributions pursuant to Section 3.3(c), if any. No interest will be paid or accrued on any dividends or other distributions payable pursuant to Section 3.3(c). In the event of a transfer of ownership of Public Common Units that is not registered in the transfer records of the Partnership, the Merger Consideration payable in respect of such Public Common Units may be paid to a transferee if the Certificate representing such Public Common Units or evidence of ownership of the Book-Entry Units is presented to the Exchange Agent, and in the case of both certificated and book-entry Public Common Units, accompanied by all documents reasonably required to evidence and effect such transfer, and the Person requesting such exchange will pay to the Exchange Agent in advance any transfer or other Taxes required by reason of the delivery of the Merger Consideration in any name other than that of the record holder of such Public Common Units, or will establish to the satisfaction of the Exchange Agent that such Taxes have been paid or are not payable. Until all such required documentation has been delivered and Certificates, if any, have been surrendered as contemplated by this Section 3.3(b), each Certificate or Book-Entry Unit will be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration upon such delivery and surrender, any cash or dividends or other distributions to which such holder is entitled pursuant to Section 3.3(c) or Section 3.3(d) and any distribution in respect of the Common Units with a record date occurring prior to the Effective Time that may have been declared by the Partnership on the Common Units in accordance with the terms of this Agreement and the Partnership Agreement and remains unpaid at the Effective Time.

(c) Dividends with Respect to Unexchanged Public Common Units. No dividends or other distributions with respect to Parent Shares issued in the Merger shall be paid to the holder of any unsurrendered Certificates or Book-Entry Units until such Certificates or Book-Entry Units are surrendered as provided in this Section 3.3. Following such surrender, subject to the effect of escheat, Tax or other applicable Laws, there shall be paid, without interest, to the record holder of the Parent Shares issued in exchange therefor (i) at the time of such surrender, all dividends or other distributions payable in respect of any such Parent Shares with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such Parent Shares with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of dividends or other distributions in respect of Parent Shares, all Parent Shares to be issued pursuant to the Merger shall be entitled to dividends or other distributions pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time.

17

(d) No Fractional Parent Shares. No certificates or scrip for Parent Shares representing fractional Parent Shares or book entry credit of the same will be issued upon the surrender of Public Common Units outstanding immediately prior to the Effective Time in accordance with Section 3.3(b), and such fractional interests will not entitle the owner thereof to vote, receive dividends or to have any other rights as a holder of any Parent Shares. Notwithstanding any other provision of this Agreement, in lieu of receiving any fraction of a Parent Share, all fractions of Parent Shares to which a holder of Public Common Units converted into the right to receive the Merger Consideration in the Merger would otherwise have been entitled shall be aggregated and rounded to three decimal places. Any holder of Public Common Units otherwise entitled to receive a fractional Parent Share but for this Section 3.3(d) shall be entitled to receive a cash payment, without interest, rounded to the nearest cent, equal to the product of (i) the aggregated amount of the fractional interest in Parent Shares to which such holder would, but for this Section 3.3(d), be entitled and (ii) an amount equal to the average of the volume weighted average price per Parent Share on the Nasdaq (as reported by Bloomberg L.P., or, if not reported therein, in another authoritative source mutually selected by Parent and the General Partner) on each of the ten (10) consecutive trading days ending with the complete trading day immediately prior to the Closing Date.

(e) No Further Rights in Public Common Units. The Merger Consideration issued upon conversion of a Public Common Unit in accordance with the terms hereof will be deemed to have been issued and paid in full satisfaction of all rights pertaining to such Public Common Unit (other than any distribution in respect of the Common Units with a record date occurring prior to the Effective Time that may have been declared by the Partnership on the Common Units in accordance with the terms of this Agreement and the Partnership Agreement and which remains unpaid at the Effective Time).

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Public Common Units on the one year anniversary of the Effective Time will be delivered to Parent upon demand by Parent and, from and after such delivery, any former holders of Public Common Units who have not theretofore complied with this Article III will thereafter look only to Parent for the Merger Consideration payable in respect of such Public Common Units, any cash in lieu of fractional Parent Shares or any dividends or other distributions with respect to Parent Shares to which they are entitled pursuant to Section 3.1 or Section 3.3(c), respectively, in each case, without any interest thereon. Any amounts remaining unclaimed by holders of Public Common Units immediately prior to such time as such amounts would otherwise escheat to or become the property of any Governmental Authority will, to the extent permitted by applicable Law, become the property of Parent. Without limitation of the foregoing, after the date that is the one-year anniversary of the Effective Time, any amounts remaining unclaimed by holders of Public Common Units will become the property of Parent, subject to the legitimate claims of any Person previously entitled thereto hereunder or under abandoned property, escheat or similar Laws. Notwithstanding anything in this Agreement to the contrary, none of the Parent Parties, the Partnership, the Surviving Entity, the General Partner, the Exchange Agent, or any other Person shall be liable to any former holder of Public Common Units for any amount properly delivered to a public official pursuant to any abandoned property, escheat or similar Law.

18

(g) Lost, Stolen or Destroyed Certificates. If any Certificate is 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 an indemnity agreement or a bond, in a customary amount, 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 and affidavit the Merger Consideration payable in respect of Public Common Units represented by such Certificate as contemplated by this Article III and pay any dividends or other distributions pursuant to Section 3.3(c) and any cash payable in lieu of fractional Parent Shares.

(h) Withholding Taxes. Each of the Parent Parties, the Surviving Entity and the Exchange Agent, as applicable, are entitled to deduct and withhold from any amounts, including the Merger Consideration, payable pursuant to this Agreement to any Person such amounts as the Parent Parties, the Surviving Entity or the Exchange Agent, as applicable, reasonably deems it is required to deduct and withhold under the Code or any provision of state, local, or foreign Tax Law, with respect to the making of such payment. Such deduction and withholding may be taken in securities, in which case the Parent Parties, the Surviving Entity or the Exchange Agent, as applicable, shall be treated as having sold such securities for an amount of cash equal to the fair market value of such securities at the time of such deemed sale. To the extent that deducted and withheld amounts (including deemed proceeds from the deemed sale of securities) are paid over to the appropriate Governmental Authority, such amounts (including securities) will be treated for all purposes of this Agreement as having been paid or issued to the Person in respect of whom such deduction and withholding was made.

(i) Book Entry Shares. All Parent Shares to be issued in the Merger will be issued in book-entry form, without physical certificates.

(j) Investment of Exchange Fund. Parent may cause the Exchange Agent to invest the cash in the Exchange Fund as directed by Parent on a daily basis, in Parent’s sole discretion; provided, however, that no such investment or loss thereon shall affect the amounts payable or timing of the amounts payable to the holders of Public Common Units pursuant to the other provisions of this Article III. Any interest and other income resulting from such investments shall be paid promptly to Parent.

Section 3.4 No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other transactions contemplated by this Agreement.

Section 3.5 Anti-Dilution Provisions. Notwithstanding any provision of this Article III to the contrary, if between the date of this Agreement and the Effective Time the number of outstanding Common Units or Parent Shares shall have been changed into a different number of units or shares or a different class or series by reason of any subdivisions, reclassifications, splits, share distributions, combinations or exchanges of Common Units or Parent Shares, as applicable, then the Merger Consideration, the Exchange Ratio and any other similar dependent item, as applicable, will be correspondingly adjusted to provide to the holders of Public Common Units the same economic effect as contemplated by this Agreement prior to such event; provided, however, that nothing in this Section 3.5 shall be deemed to permit or authorize any party hereto to effect any such change that it is not otherwise authorized or permitted to be undertaken pursuant to this Agreement.

19

Section 3.6 Treatment of Awards. Prior to the Effective Time, Parent, the General Partner and the Partnership shall take all action as may be necessary or required in accordance with applicable Law and each of the Partnership Long-Term Incentive Plans and the Parent Equity Plan (including the award agreements in respect of awards granted thereunder) to give effect to this Section 3.6 as follows: as of the Effective Time, (i) each Partnership Phantom Unit (other than the Director Phantom Units) that is outstanding immediately prior to the Effective Time, shall cease to relate to or represent any right to receive Common Units and shall be converted at the Effective Time into an award of restricted stock units relating to a number of Parent Shares (“Parent RSUs”) equal to the product of (A) the number of Common Units subject to the corresponding Partnership Phantom Unit as of immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio, such product rounded up to the nearest whole share, and with such Parent RSU otherwise on the same terms and conditions as were applicable to the corresponding Partnership Phantom Units, including any applicable payment timing provisions and distribution equivalent rights, as applicable (and, if applicable, dividend equivalent rights relating to dividends declared with respect to Parent Common Stock during the period beginning at the Effective Time and ending on the date of settlement of such Parent RSU), and (ii) each Partnership Phantom Unit held by a non-employee director whose service to the Partnership or its Affiliates will terminate upon the consummation of the Merger (each a “Director Phantom Unit”) shall become fully vested and shall be automatically converted into the right to receive, with respect to each Common Unit subject thereto, the Merger Consideration, plus any accrued but unpaid amounts in relation to distribution equivalent rights, in accordance with the applicable payment timing provisions set forth in the award agreement evidencing such Director Phantom Unit (and, if applicable, dividend equivalent rights relating to dividends declared with respect to Parent Common Stock during the period beginning at the Effective Time and ending on the date of settlement of such Director Phantom Unit). The conversion of a Director Phantom Unit as provided in clause (ii) of the immediately preceding sentence shall be deemed a release of any and all rights the holder thereof had or may have had in respect of such Director Phantom Unit other than, from and after the Effective Time, the right to receive the Merger Consideration, plus any accrued but unpaid amounts in relation to distribution equivalent rights (and dividend equivalent rights as described in such clause if applicable) in respect of each Common Unit subject to such converted Director Phantom Unit. From and after the Effective Time, the former holder of any Partnership Phantom Unit (other than the Director Phantom Units) shall only be entitled to receive Parent RSUs in respect of such Partnership Phantom Unit, which Parent RSUs will include a right to receive payment of any amounts with respect to accrued distribution equivalent right payments as of the Closing (and dividend equivalent rights beginning at the Effective Time if applicable) in accordance with and subject to the same vesting, forfeiture, payment timing and other provisions as applied under the corresponding Partnership Phantom Unit. Except as otherwise provided in this Section 3.6, each such Parent RSU shall continue to have and be subject to the same vesting and other terms and conditions as applied to the corresponding Partnership Phantom Unit immediately before the Effective Time. If, as of the Effective Time, Parent does not have reserved for issuance a sufficient number of shares of Parent Common Stock for delivery with respect to the Parent RSUs issued by it in accordance with this Section 3.6, Parent shall take all corporate action necessary to reserve for issuance such number of shares of Parent Common Stock. As of the Effective Time, Parent shall have on file a registration statement on Form S-8 (or any successor

20

or other appropriate form) with respect to shares of Parent Common Stock subject to such Parent RSUs and shall maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such Parent RSUs remain outstanding.

(a) From and after the Effective Time, to the fullest extent permitted under applicable Laws, Parent shall, and shall cause the Surviving Entity to, (i) indemnify and hold harmless each Indemnified Person against any reasonable costs or expenses (including reasonable attorneys’ fees and all other reasonable costs, expenses and obligations (including experts’ fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Proceeding, including any Proceeding relating to a claim for indemnification or advancement brought by an Indemnified Person), judgments, fines, losses, claims, damages or liabilities, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of any thereof) in connection with any actual or threatened Proceeding, and, upon receipt by Parent of an undertaking by or on behalf of the Indemnified Person to repay such amount if it shall be determined in a final and non-appealable judgment entered by a court of competent jurisdiction that the Indemnified Person is not entitled to be indemnified, provide advancement of

45

expenses with respect to each of the foregoing to, all Indemnified Persons; and (ii) honor the provisions regarding elimination of liability of officers and directors, indemnification of officers, directors and employees and advancement of expenses contained in the Organizational Documents of the Partnership and the General Partner immediately prior to the Effective Time, and ensure that the Organizational Documents of the Partnership and the General Partner or any of their respective successors or assigns, if applicable, shall, for a period of six years following the Effective Time, contain provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors, officers and employees of the Partnership and the General Partner than are presently set forth in such Organizational Documents. Any right of an Indemnified Person pursuant to this Section 6.6(a) shall not be amended, repealed, terminated or otherwise modified at any time in a manner that would adversely affect the rights of such Indemnified Person as provided herein, and shall be enforceable by such Indemnified Person and their respective heirs and Representatives against Parent, the Partnership and the General Partner and their respective successors and assigns.

(b) The Surviving Entity, or Parent on behalf of the Surviving Entity if Parent, in its sole discretion, so elects, shall maintain in effect for a period of six years following the Effective Time the Partnership’s current directors’ and officers’ liability insurance policies covering acts or omissions occurring at or prior to the Effective Time with respect to Indemnified Persons (provided, that the Surviving Entity, or Parent on behalf of the Surviving Entity if Parent so elects, may substitute therefor policies with reputable carriers of at least the same coverage containing terms and conditions that are no less favorable to the Indemnified Persons); provided, however, that in no event shall the Surviving Entity or Parent, as applicable, be required to expend pursuant to this Section 6.6(b) more than an amount per year equal to 300% of current annual premiums paid by the Partnership for such insurance (the “Maximum Amount”). In the event that, but for the proviso to the immediately preceding sentence, the Surviving Entity would be required to expend more than the Maximum Amount, the Surviving Entity, or Parent on behalf of the Surviving Entity if Parent had so elected to provide such insurance, shall obtain the maximum amount of such insurance as is available for the Maximum Amount. If Parent, in its sole discretion, elects, then, in lieu of the obligations of the Surviving Entity under this Section 6.6(b), the Partnership or Parent may (but shall be under no obligation to), prior to the Effective Time, purchase a prepaid “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 Persons in their capacity as such; provided, that in no event shall the cost of such policy exceed six times the Maximum Amount.

(c) The rights of any Indemnified Person under this Section 6.6 shall be in addition to any other rights such Indemnified Person may have under the Parent Organizational Documents, the Organizational Documents of each of the Partnership, the General Partner, the Surviving Entity or any Subsidiary of Parent or the Partnership, any indemnification agreements, or the DLLCA or DRULPA. The provisions of this Section 6.6 shall survive the consummation of the transactions contemplated by this Agreement and are expressly intended to benefit each of the Indemnified Persons and their respective heirs and Representatives. If Parent, the Surviving Entity and/or the General Partner, or any of their respective successors or assigns (i) consolidates with or merges into any other Person or (ii) transfers or conveys all or substantially all of their businesses or assets to any other Person, then, in each such case, to the extent necessary, a proper provision shall be made so that the successors and assigns of Parent, the Surviving Entity and/or the General Partner shall assume the obligations of Parent, the Surviving Entity and the General Partner set forth in this Section 6.6.

46

Section 6.7 Fees and Expenses. Except as otherwise provided in Section 8.2 and Section 8.3, all fees and expenses incurred in connection with the transactions contemplated by this Agreement including all legal, accounting, financial advisory, consulting and all other fees and expenses of third parties incurred by a party in connection with the negotiation and effectuation of the terms and conditions of this Agreement and the transactions contemplated by this Agreement, shall be the obligation of the respective party incurring such fees and expenses, except (a) Parent and the Partnership shall each bear and pay one half of the expenses incurred in connection with the filing, printing and mailing of the Registration Statement and the Information Statement and (b) Parent shall pay all costs and fees of the Exchange Agent and all expenses associated with the exchange process.

Section 6.8 Section 16 Matters. Prior to the Effective Time, the Partnership shall take all such steps as may be required (to the extent permitted under applicable Laws) to cause any dispositions of Common Units (including derivative securities with respect to Common Units) or acquisitions of Parent Common Stock (including derivative securities with respect to Parent Common Stock) resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Partnership, or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 6.9 Stock Exchange Listing, Delisting and Deregistration.

(a) Parent shall use its reasonable best efforts to cause the Parent Shares to be issued in connection with the Merger to be authorized for listing on the Nasdaq (subject to official notice of issuance) prior to the Effective Time. Prior to the Closing, Parent shall submit a listing of additional shares notification form to the Nasdaq with respect to such Parent Shares in accordance with the requirements of the Nasdaq.

(b) Prior to the Closing, the Partnership will cooperate and use its reasonable best efforts to cause the delisting of Common Units from the Nasdaq and the deregistration of such securities under the Exchange Act as promptly as practicable following the Closing in compliance with applicable Law.

Section 6.10 Dividends and Distributions. Subject to Section 6.2(a), after the date of this Agreement and until the Effective Time, each of Parent and the Partnership shall coordinate with the other regarding the timing of the Closing, as well as the timing of any declaration of any dividends or distributions in respect of Parent Common Stock and Common Units and the record dates and payment dates relating thereto, it being the intention of the parties that holders of Common Units shall not receive, for any quarter, distributions both in respect of Common Units and also dividends in respect of Parent Common Stock that they receive in exchange therefor in the Merger, but that they shall receive for any such quarter either: (i) only distributions in respect of Common Units or (ii) only dividends in respect of Parent Common Stock that they receive in exchange therefor in the Merger.

47

Section 6.11 Conflicts Committee. Prior to the earlier of the Effective Time and the termination of this Agreement, Parent shall not, and it shall not permit any of its Subsidiaries to, take any action intended to cause the General Partner to, without the consent of a majority of the then existing members of the Conflicts Committee, eliminate the Conflicts Committee, revoke or diminish the authority of the Conflicts Committee, increase the size of the Conflicts Committee, or remove or cause the removal of any director of the General Partner who is a member of the Conflicts Committee either as a director or as a member of such committee. For the avoidance of doubt, this Section 6.11 shall not apply to the removal of any director for Cause or the filling, in accordance with the provisions of the General Partner Company Agreement, of any vacancies in the Conflicts Committee caused by the resignation, death or incapacity of any such director or any such removal of a director for Cause.

Section 6.12 Performance by the General Partner. Subject to Section 9.3 and Section 9.4, Parent will cause the General Partner, the Partnership and their respective Subsidiaries to comply with the provisions of this Agreement. Notwithstanding the foregoing, it is understood and agreed that actions or inactions by the Partnership and the General Partner and their respective Subsidiaries shall not be deemed to be breaches or violations or failures to perform by Parent of any of the provisions of this Agreement unless such action or inaction was or was not taken, in either case, at the direction of Parent. In no event shall the General Partner or the Partnership have any liability for, or be deemed to breach, violate or fail to perform any of the provisions of this Agreement by reason of, any action taken or omitted to be taken by the General Partner, the Partnership, any of their respective Subsidiaries or any of their respective Representatives at the direction of Parent, any of its Subsidiaries or any of their respective Representatives.

Section 6.13 Tax Matters. For U.S. federal income tax purposes (and for purposes of any applicable state, local or foreign Tax that follows the U.S. federal income tax treatment), the parties intend for the Merger to qualify as a reorganization within the meaning of Section 368(a) of the Code and shall not take any action reasonably likely to cause the Merger not to so qualify. This Agreement is intended to constitute a “plan of reorganization” within the meaning of the Treasury Regulations Section 1.368-2(g). The parties will prepare and file all Tax Returns consistent with the foregoing and will not take any inconsistent position on any Tax Return except as otherwise required by applicable Law.

Section 6.14 Takeover Statutes. Parent shall not, and shall cause its Subsidiaries not to, take any action that would, or would reasonably be expected to, cause any Takeover Law to become applicable to this Agreement, the Merger, the Parent Stock Issuance or the other transactions contemplated by this Agreement or related thereto. If any Takeover Law shall become applicable to this Agreement, the Merger or the other transactions contemplated by this Agreement or related thereto, Parent, the Parent Board, the General Partner, the GP Board and the Conflicts Committee shall use reasonable best efforts to take such actions so that the transactions contemplated by this Agreement, including the Merger and the Parent Stock Issuance, may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise use reasonable best efforts to eliminate or minimize the effects of such statute or regulation on the transactions contemplated by this Agreement, including the Merger and the Parent Stock Issuance.

48

Section 6.15 Securityholder Litigation. The Partnership and the General Partner shall give Parent prompt notice and the opportunity to participate in the defense or settlement of any securityholder litigation against the Partnership and the General Partner and/or their directors (as applicable) relating to the transactions contemplated by this Agreement and no such settlement shall be agreed to without the prior written consent of Parent, which consent shall not be unreasonably withheld, conditioned or delayed; provided, that the Partnership and the General Partner shall in any event control such defense and/or settlement and shall not be required to provide information if doing so would be reasonably expected to violate the confidentiality obligations of such party or threaten the loss of any attorney-client privilege or other applicable legal privilege.

Section 6.16 Treatment of Partnership Indebtedness.

(a) Credit Agreement. Upon written request of Parent, the Partnership shall, and shall cause all applicable Group Members to, deliver all notices and take all other actions reasonably requested by Parent that are required to facilitate in accordance with the terms thereof the termination of all commitments outstanding under the Partnership Revolving Credit Facility, the repayment in full of all obligations, if any, outstanding thereunder, the release of all Liens, if any, securing such obligations, and the release of guarantees in connection therewith on the Closing Date as of the Effective Time (such termination, repayment and releases, the “Credit Facility Terminations”). In furtherance and not in limitation of the foregoing, upon written request of Parent made at least five Business Days prior to the Closing Date, the Partnership shall, and shall cause all applicable Group Members to, use commercially reasonable efforts to deliver to Parent at least two Business Days prior to the Closing Date (with drafts being delivered in advance as reasonably requested by Parent), (i) an executed payoff letter, in each case, with respect to the Partnership Revolving Credit Facility (the “Payoff Letter”), and (ii) to the extent allowed by the applicable agent under such Indebtedness to be delivered prior to the payment of all amounts under the Payoff Letter, to deliver in escrow subject to the payoff of the amounts under the Payoff Letter all related release documentation, in each case, in form and substance customary for transactions of this type, from the applicable agent on behalf of the Persons to whom such Indebtedness is owed, which Payoff Letter together with any related release documentation shall, among other things, include the payoff amount and provide that Liens (and guarantees), if any, granted in connection therewith relating to the assets, rights and properties of the Partnership and the Group Members securing such Indebtedness and any other obligations secured thereby, shall, upon the payment of the amount set forth in the applicable Payoff Letter on the Closing Date as of the Effective Time, be released and terminated. Notwithstanding anything herein to the contrary, in no event shall this Section 6.16(a) require the Partnership or any of the Group Members to cause the Credit Facility Terminations to be effective unless and until the Effective Time has occurred.

(b) Senior Notes. Upon written request of Parent, the Partnership shall, and shall cause all applicable Group Members to, and shall use commercially reasonable efforts to cause its and their Representatives to, as applicable, (i) deliver to the trustee under the Senior Notes Indenture at or prior to the Effective Time, a notice of optional redemption for up to all of the outstanding aggregate principal amount of the Senior Notes, pursuant to the redemption provisions of the Senior Notes Indenture and the Senior Notes, which notice shall be subject to the occurrence of the Effective Time, and (ii) provide assistance reasonably requested by the Parent to facilitate the redemption of the Senior Notes Indenture identified by the Parent and the satisfaction and

49

discharge of the Senior Notes identified by the Parent at the Effective Time pursuant to the redemption and satisfaction and discharge provisions, respectively, and other applicable provisions of the Senior Notes Indenture (each, a “Discharge”) and, in each case, take any other actions reasonably requested by Parent that are customary or necessary in connection therewith, including the execution and delivery by the Partnership, all applicable Group Members or their Representatives (as applicable) of customary officers’ certificates and legal opinions, respectively, to the trustee under the Senior Notes Indenture, to the extent such certificates and opinions are required thereby or reasonably requested by the Trustee. Notwithstanding anything herein to the contrary, in no event shall this Section 6.16(b) require the Partnership or any of the Group Members to cause any redemption or Discharge to be effective unless and until the Effective Time has occurred and Parent has provided or caused to be provided to the Trustee under the Senior Notes Indenture funds (or Parent has directed the Partnership or any of the Partnership’s Subsidiaries to use funds on their balance sheet) sufficient to effect any such redemption or Discharge in compliance with the provisions of the Senior Notes Indenture.

(a) by the mutual written consent of Parent and the Partnership duly authorized by the Parent Board and the Conflicts Committee, respectively;

(b) by either of Parent or the Partnership:

(i) if the Closing shall not have been consummated on or before December 31, 2022 (the “Outside Date”); provided, however, that the right to terminate this Agreement under this Section 8.1(b)(i) shall not be available (A) to Parent or the Partnership if the failure of the Closing to occur by the Outside Date was due to the failure of, in the case of Parent, a Parent Party, or, in the case of the Partnership, the Partnership or the General Partner, to perform and comply in all material respects with the covenants and agreements to be performed or complied with by it prior to the Closing or (B) to Parent or the Partnership if, in the case of Parent, the Partnership or the General Partner, or, in the case of the Partnership, a Parent Party, has filed (and is then pursuing) an action seeking specific performance as permitted by Section 9.9; or

52

(ii) if any Restraint having the effect set forth in Section 7.1(b) shall be in effect and shall have become final and nonappealable; provided, however, that the right to terminate this Agreement under this Section 8.1(b)(ii) shall not be available to Parent or the Partnership if such Restraint was due to the failure of, in the case of Parent, a Parent Party, or, in the case of the Partnership, the Partnership or the General Partner, to perform any of its obligations under this Agreement in any material respect;

(c) by Parent if the Partnership or the General Partner shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement (or if any of the representations or warranties of the Partnership or the General Partner set forth in this Agreement shall fail to be true), which breach or failure (i) would (if it occurred or was continuing as of the Closing Date) give rise to the failure of a condition set forth in Section 7.2(a)(i) or Section 7.2(b) and (ii) is incapable of being cured, or is not cured, by the Partnership or the General Partner within 30 days following receipt of written notice from Parent of such breach or failure; provided, however, that Parent shall not have the right to terminate this Agreement pursuant to this Section 8.1(c) if a Parent Party is then in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement; or

(d) by the Partnership (which termination may be effected for the Partnership by the Conflicts Committee without the consent, authorization or approval of the GP Board) if Parent shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement (or if any of the representations or warranties of Parent set forth in this Agreement shall fail to be true), which breach or failure (i) would (if it occurred or was continuing as of the Closing Date) give rise to the failure of a condition set forth in Section 7.3(a)(i) or Section 7.3(b) and (ii) is incapable of being cured, or is not cured, by Parent within 30 days following receipt of written notice from the Partnership of such breach or failure; provided, that the Partnership shall not have the right to terminate this Agreement pursuant to this Section 8.1(d) if the Partnership or the General Partner is then in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement.

Section 8.2 Effect of Termination. In the event of the termination of this Agreement as provided in Section 8.1, written notice thereof shall be given to the other party or parties, specifying the provision of this Agreement pursuant to which such termination is made, and this Agreement shall forthwith become null and void (other than the provisions in Section 6.7, this Section 8.2, Section 8.3 and Article IX, all of which shall survive termination of this Agreement), and, except as otherwise provided in this Section 8.2, there shall be no liability on the part of any of any Parent Party, the Partnership or the General Partner or their respective Representatives, directors, officers and Affiliates; provided, however, that no such termination shall relieve any party hereto from (a) its obligation to pay the Parent Expense Reimbursement or the Partnership Expense Reimbursement, as applicable, if, as and when required pursuant to Section 8.3, (b) any liability for any failure to consummate the Merger and the other transactions contemplated by this Agreement when required pursuant to this Agreement or (c) any liability for intentional fraud or a Willful Breach of any covenant or other agreement contained in this Agreement. Notwithstanding the foregoing, in no event shall the General Partner or the Partnership have any liability for any matter set forth in the proviso of the preceding sentence for any action taken or omitted to be taken by the General Partner, the Partnership, any of their respective Subsidiaries or any of their respective Representatives at the direction of Parent, any of its Subsidiaries or any of their respective Representatives. For purposes of this Agreement, “Willful Breach” shall mean a material breach of this Agreement that is a consequence of a deliberate act or a deliberate failure to act by the breaching party with the knowledge that the taking of such act (or the failure to take such act) would (i) cause a material breach of this Agreement and (ii) prevent or materially delay the Closing.

53

Section 8.3 Expenses.

(a) In the event of termination of this Agreement by Parent pursuant to Section 8.1(c) (Partnership Uncured Breach), then the Partnership shall promptly, but in no event later than five Business Days after receipt of an invoice (with supporting documentation) therefor from Parent, pay Parent’s designee all of the reasonably documented out-of-pocket expenses (including all fees and expenses of counsel, accountants, investment bankers, financing sources, hedging counterparties, experts and consultants) incurred by Parent and its Affiliates in connection with this Agreement and the transactions contemplated by this Agreement up to a maximum amount of $3,500,000 (the “Parent Expense Reimbursement”).

(b) In the event of termination of this Agreement by the Partnership pursuant to Section 8.1(d) (Parent Uncured Breach), then Parent shall promptly, but in no event later than five Business Days after receipt of an invoice (with supporting documentation) therefor from the Partnership, pay the Partnership’s designee all of the reasonably documented out-of-pocket expenses (including all fees and expenses of counsel, accountants, investment bankers, financing sources, hedging counterparties, experts and consultants) incurred by the Partnership and its Affiliates in connection with this Agreement and the transactions contemplated by this Agreement up to a maximum amount of $3,500,000 (the “Partnership Expense Reimbursement”).

(c) Each of the parties hereto acknowledges that the Parent Expense Reimbursement and Partnership Expense Reimbursement are not intended to be a penalty, but rather are liquidated damages in a reasonable amount that will compensate the other party, as applicable, in the circumstances in which such amounts are due and payable and which do not involve intentional fraud or Willful Breach, for the efforts and resources expended and opportunities forgone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated by this Agreement, which amount would otherwise be impossible to calculate with precision. In no event shall a party be entitled to more than one payment of the Parent Expense Reimbursement and Partnership Expense Reimbursement, as applicable, in connection with a termination of this Agreement pursuant to which such amounts are payable.

At any time prior to the Effective Time, this Agreement may be amended or supplemented in any and all respects by written agreement of the parties, by action taken or authorized by the Parent Board and the GP Board; provided, however, that the GP Board may not take or authorize any such action unless it has been approved by the Conflicts Committee; provided, further, that there shall be no amendment or change to the provisions of this Agreement that by applicable Laws, the Partnership Agreement or stock exchange rule would require further approval by Limited Partners without obtaining the requisite approval by the Limited Partners.

Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

Section 9.8 Governing Law; Jurisdiction; Waiver of Jury Trial.

(a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, applicable to contracts executed in and to be performed entirely within that State.

(b) Each of the parties hereto irrevocably agrees that any legal action or Proceeding with respect to this Agreement and the rights and obligations arising hereunder, shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware). Each of the parties hereto consents to service being made through the notice procedures set forth in Section 9.10, irrevocably submits with regard to any such action or Proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts. Each of the parties hereto irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any action or Proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in accordance with this Section 9.8, (ii) any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by the applicable Laws, any claim that (A) the suit, action or Proceeding in such court is brought in an inconvenient forum, (B) the venue of such suit, action or Proceeding is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. Each party hereto expressly acknowledges that the foregoing waiver is intended to be irrevocable under the Law of the State of Delaware and of the United States of America; provided, however, that each such party’s consent to jurisdiction and service contained in this Section 9.8(b) is solely for the purpose referred to in this Section 9.8(b) and shall not be deemed to be a general submission to such courts or in the State of Delaware other than for such purpose.

56

(c) EACH PARTY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

Section 9.9 Specific Performance. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and it is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, in accordance with this Section 9.9 in the Delaware Court of Chancery or any other state or federal court sitting in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief as provided herein on the basis that (a) either party has an adequate remedy at law or (b) an award of specific performance is not an appropriate remedy for any reason at law or equity (it being understood that nothing in this sentence shall prohibit the parties hereto from raising other defenses to a claim for specific performance or other equitable relief under this Agreement). Each party further agrees that no party shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 9.9, and each party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

Exhibit 99.1

Diamondback Energy, Inc. Announces Agreement to Acquire Publicly Held Units of Rattler Midstream LP

MIDLAND, Texas, May 16, 2022 (GLOBE NEWSWIRE) — Diamondback Energy, Inc. (NASDAQ: FANG) (“Diamondback”) and Rattler Midstream LP (NASDAQ: RTLR) (“Rattler”) today announced that, on May 15, 2022, they entered into a definitive agreement for Diamondback to acquire all of the publicly held common units representing the limited partner interests in Rattler not already owned by Diamondback and its subsidiaries. The agreement provides for an all-stock transaction whereby each public unitholder of Rattler would receive 0.113 of a share of common stock in Diamondback in exchange for each Rattler common unit owned, an exchange ratio that implies a premium of 17.3% for Rattler common units based on the closing prices of Rattler’s common units and Diamondback’s common stock as of May 13, 2022, and a premium of 9.3% based on Rattler’s and Diamondback’s 30 day volume-weighted average trading price as of the same date.

“The energy landscape has transformed dramatically since Rattler was taken public in 2019, and we believe this agreement to merge companies is in the best interests of both Diamondback and Rattler stakeholders,” stated Travis Stice, Chief Executive Officer of Diamondback and of the general partner of Rattler. “This merger will allow both companies to benefit from the simplicity and scale of the combined entity going forward.”

The Conflicts Committee of the board of directors of Rattler’s general partner, composed of independent directors, unanimously approved the merger agreement after consultation with its independent legal and financial advisors. The merger agreement was subsequently unanimously approved by the board of directors of Rattler’s general partner. Diamondback E&P LLC, a wholly owned subsidiary of Diamondback and the holder of a majority of the outstanding units of Rattler, has voted its units to approve the transaction. The transaction is expected to close in the third quarter of 2022, subject to customary closing conditions.

Forward-Looking Statements

This news release contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, which involve risks, uncertainties, and assumptions. All statements, other than statements of historical fact, including statements regarding Diamondback’s and Rattler’s: future performance; business strategy; future operations; estimates and projections of revenues, losses, costs, expenses, returns, cash flow, and financial position; anticipated benefits of strategic transactions (including acquisitions and divestitures); and plans and objectives of management (including plans for future cash flow from operations) are forward- looking statements. These statements also include, but are not limited to, statements regarding: the expected benefits of the proposed transaction to Diamondback and Rattler and their shareholders and unitholders, respectively, the anticipated completion of the proposed transaction and the timing thereof. When used in this news release, the words “aim,” “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “future,” “guidance,” “intend,” “may,” “model,” “outlook,” “plan,” “positioned,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” “would,” and similar expressions (including the negative of such terms) as they relate to Diamondback and Rattler are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. Although Diamondback and Rattler each believes that the expectations and assumptions reflected in its forward-looking statements are reasonable as and when made, they involve risks and uncertainties that are difficult to predict and, in many cases, beyond Diamondback’s and Rattler’s control. Accordingly, forward-looking statements are not guarantees of future performance and Diamondback and Rattler’s actual outcomes could differ materially from what Diamondback and Rattler have expressed in their forward-looking statements.

Factors that could cause the outcomes to differ materially include (but are not limited to) the following: changes in supply and demand levels for oil, natural gas, and natural gas liquids, and the resulting impact on the price for those commodities; the impact of public health crises, including epidemic or pandemic diseases such as the COVID-19 pandemic, and any related company or government policies or actions; actions taken by the members of OPEC and Russia affecting the production and pricing of oil, as well as other domestic and global political, economic, or diplomatic developments, including any impact of the ongoing Russian-Ukrainian conflict on the global energy markets and geopolitical stability; regional supply and demand factors, including delays, curtailment delays or interruptions of production, or governmental orders, rules or regulations that impose production limits; federal and state legislative and regulatory initiatives relating to hydraulic fracturing, including the effect of existing and future laws and governmental regulations; and the risks and other factors disclosed in Diamondback’s and Rattler’s filings with the Securities and Exchange Commission, including their respective Forms 10-K, 10-Q and 8-K, which can be obtained free of charge on the Securities and Exchange Commission’s web site at http://www.sec.gov.

In light of these factors, the events anticipated by Diamondback’s and Rattler’s forward-looking statements may not occur at the time anticipated or at all. Moreover, Diamondback and Rattler each operates in a very competitive and rapidly changing environment and new risks emerge from time to time. Neither Diamondback nor Rattler can predict all risks, nor can they assess the impact of all factors on their respective businesses or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those anticipated by any forward-looking statements they may make. Accordingly, you should not place undue reliance on any forward-looking statements made in this news release. All forward-looking statements speak only as of the date of this news release or, if earlier, as of the date they were made. Neither Diamondback nor Rattler intends to, and each disclaims any obligation to, update or revise any forward- looking statements unless required by applicable law.
