EFFECT ON THE CAPITAL STOCK OF THE CONSTITUENT CORPORATIONS

2.1 Conversion of Securities.

(a) Crosstex and Rangers Merger Sub. Immediately prior to the Crosstex Effective Time, Devon shall contribute or cause to be contributed to New Public Rangers $100,000,000 in cash to pay the aggregate Cash Consideration. At the Crosstex Effective Time, by virtue of the Crosstex Merger and without any action on the part of any party or the holders of any securities of Crosstex or Rangers Merger Sub:

(i) Generally. Each share of Crosstex Common Stock issued and outstanding immediately prior to the Crosstex Effective Time (other than any shares of Crosstex Common Stock to be cancelled pursuant to Section 2.1(a)(ii) or Section 2.1(a)(iv) and other than Dissenting Shares) shall be converted into the right to receive (A) an amount in cash equal to the quotient of (1) $100,000,000 divided by (2) the number of shares of Crosstex Common Stock issued and outstanding immediately prior to the Crosstex Effective Time (other than any shares of Crosstex Common Stock to be cancelled pursuant to Section 2.1(a)(ii) or Section 2.1(a)(iv)) (the “Cash Consideration”) and (B) one (1) validly issued, fully paid and nonassessable New Public Rangers Common Unit (the “Unit Consideration” and, together with the Cash Consideration, the “Crosstex Merger Consideration”). All such shares of Crosstex Common Stock that were issued and outstanding immediately prior to the Crosstex Effective Time shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist and each holder of a certificate or certificates which immediately prior to the Crosstex Effective Time represented any such shares of Crosstex Common Stock (“Crosstex Certificates”) or book-entry shares which immediately prior to the Crosstex Effective Time represented shares of Crosstex Common Stock (“Crosstex Book-Entry Shares”) shall thereafter cease to have any rights with respect to such shares of Crosstex Common Stock, except the right to receive the Crosstex Merger Consideration and as provided by Law.

(ii) Devon and New Acacia Owned Shares. Each share of Crosstex Common Stock owned by Devon or any of its wholly-owned Subsidiaries shall be cancelled and shall cease to exist and no Crosstex Merger Consideration or other consideration shall be delivered in exchange therefor.

(iii) Rangers Merger Sub Common Stock. Each share of common stock of Rangers Merger Sub, par value $0.01 per share, issued and outstanding immediately prior to the Crosstex Effective Time shall be converted into one share of common stock of Crosstex Surviving Corporation, par value $0.01 per share, which shall constitute the only outstanding shares of common stock of Crosstex Surviving Corporation.

(iv) Cancellation of Treasury Shares. Each share of Crosstex Common Stock held in the Crosstex treasury and each share of Crosstex Common Stock, if any, owned by any wholly-owned Subsidiary of Crosstex immediately prior to the Crosstex Effective Time shall be cancelled and shall cease to exist without any conversion thereof.

(b) New Acacia and Boomer Merger Sub. At the Devon Effective Time, by virtue of the Devon Merger and without any action on the part of any party or the holders of any securities of New Acacia or Boomer Merger Sub:

(i) Generally. The sole share of New Acacia Common Stock issued and outstanding immediately prior to the Devon Effective Time shall be converted into the right to receive 115,495,669 validly issued, fully paid and nonassessable New Public Rangers Class B Common Units (the “Devon Merger Consideration”). All such shares of New Acacia Common Stock that were issued and outstanding immediately prior to the Devon Effective Time shall no longer be outstanding and shall automatically be cancelled and shall cease to exist and each holder of a certificate or certificates which immediately prior to the Devon Effective Time represented any such shares of New Acacia Common Stock (“New Acacia Certificates”) shall thereafter cease to have any rights with respect to such shares of New Acacia Common Stock. Without any action on the part of holders of New Acacia Common Stock, all outstanding New Acacia Certificates shall, from and after the Devon Effective Time and upon surrender of the certificate or certificates for New Acacia Common Stock for cancellation to the Exchange Agent, represent the right to receive the Devon Merger Consideration with respect to each share of New Acacia Common Stock represented thereby immediately prior to the Devon Effective Time. Promptly following the Devon Effective Time, the parties shall cause the transfer agent of New Public Rangers to issue and deliver to the sole stockholder of New Acacia immediately prior to the Devon Effective Time, the Devon Merger Consideration (in the form of book-entry interests, unless such stockholder expressly requests that such interests be delivered in certificated form) in respect of such New Acacia Common Stock.

(ii) Boomer Merger Sub Common Stock. Each share of common stock of Boomer Merger Sub, par value $0.01 per share, issued and outstanding immediately prior to the Devon Effective Time shall be converted into one share of common stock of Devon Surviving Corporation, par value $0.01 per share, which shall constitute the only outstanding shares of common stock of Devon Surviving Corporation.

(iii) Cancellation of Treasury Shares. Each share of New Acacia Common Stock held in the New Acacia treasury and each share of New Acacia Common Stock, if any, owned by any Subsidiary of Devon immediately prior to the Devon Effective Time shall be cancelled and shall cease to exist without any conversion thereof.

2.2 Appraisal Rights. Notwithstanding anything in this Agreement to the contrary and to the extent available under the DGCL, shares of Crosstex Common Stock that are outstanding immediately prior to the Crosstex Effective Time and that are held by holders of shares of Crosstex Common Stock who shall have neither voted in favor of the Crosstex Merger nor consented thereto in writing and who shall have demanded properly in writing appraisal for such shares of Crosstex Common stock in accordance with Section 262 of the DGCL

(collectively, the “Dissenting Shares”) shall not be converted into, or represent the right to receive, the Crosstex Merger Consideration. Such Crosstex stockholders shall be entitled instead to receive payment of the fair value of such shares of Crosstex Common Stock in accordance with the provisions of Section 262 of the DGCL and at the Crosstex Effective Time, all Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and the holders of such shares shall cease to have any rights with respect thereto except as set forth in this Section 2.2, except that such Dissenting Shares held by holders of shares of Crosstex Common Stock who shall have failed to perfect or shall have effectively withdrawn or lost their rights to appraisal of such shares of Crosstex Common Stock under Section 262 of the DGCL shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Crosstex Effective Time, the right to receive the Crosstex Merger Consideration, without interest thereon, in accordance with Section 2.1(a). Crosstex shall deliver prompt notice to Devon of any demands for appraisal of any shares of Crosstex Common Stock, attempted withdrawals of such demands and any other instruments served pursuant to the DGCL that are received by Crosstex for appraisal of any shares of Crosstex Common Stock, and provide Devon with the opportunity to participate in and control all negotiations and proceedings with respect to demands for appraisal under the DGCL. Prior to the Crosstex Effective Time, Crosstex shall not, without the prior written consent of Devon, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

2.3 Exchange of Crosstex Certificates.

(a) Exchange Agent. Prior to the Crosstex Effective Time, Devon shall cause New Public Rangers to deposit with a commercial bank or trust company designated by Devon and reasonably satisfactory to Crosstex (the “Exchange Agent”), for the benefit of the holders of shares of Crosstex Common Stock, book-entry interests (which, to the extent subsequently requested, shall be exchanged for certificates) representing the total number of New Public Rangers Common Units issuable as Unit Consideration and an amount of cash sufficient to effect the delivery of the Cash Consideration pursuant to the Crosstex Merger. Following the Crosstex Effective Time, New Public Rangers agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any dividends or other distributions pursuant to Section 2.3(c) that may be payable following the Crosstex Effective Time (such amounts, together with the Unit Consideration and the Cash Consideration, the “Exchange Fund”).

(b) Exchange Procedures.

(i) Holders of Crosstex Certificates. New Public Rangers shall instruct the Exchange Agent to promptly (and in any event no more than five (5) Business Days) after the Crosstex Effective Time, mail to each holder of record of a Crosstex Certificate (A) a letter of transmittal (which shall be in customary form and shall specify that delivery shall be effected, and risk of loss and title to the Crosstex Certificates shall pass, only upon proper delivery of the Crosstex Certificates to the Exchange Agent) and (B) instructions for use in effecting the surrender of the Crosstex Certificates in exchange for the Crosstex Merger Consideration payable in respect of the shares of Crosstex Common Stock formerly represented by such Crosstex Certificates. Upon surrender of a Crosstex Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, properly completed and duly executed, and such other documents as may be

reasonably required pursuant to such instructions, the Exchange Agent shall issue and deliver to the holder of such Crosstex Certificate (1) the number of whole New Public Rangers Common Units (in the form of book-entry interests, unless the holder of such Crosstex Certificate expressly requests that such interests be delivered in certificated form) and (2) a check in an amount equal to the aggregate amount of Cash Consideration that such holder has the right to receive, in each case, in respect of the shares of Crosstex Common Stock formerly represented by such Crosstex Certificate, and the Crosstex Certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of shares of Crosstex Common Stock that is not registered in the transfer records of Crosstex, the Crosstex Merger Consideration payable in respect of such shares of Crosstex Common Stock may be paid to a transferee if the Crosstex Certificate formerly representing such shares of Crosstex Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer Taxes have been paid. Until surrendered as contemplated by this Section 2.3, each Crosstex Certificate shall be deemed at any time after the Crosstex Effective Time to represent only the right to receive upon such surrender the Crosstex Merger Consideration payable in respect of the shares of Crosstex Common Stock formerly represented by such Crosstex Certificate and any dividends or other distributions to which such holder is entitled pursuant to Section 2.3(c), in each case, without any interest thereon, except for Crosstex Certificates in respect of Dissenting Shares, which shall represent the right to receive the consideration due with respect to such Dissenting Shares in accordance with Section 2.2 and to the extent provided by Section 262 of the DGCL.

(ii) Holders of Crosstex Book-Entry Shares. Promptly (and in any event no more than two (2) Business Days) after the Crosstex Effective Time, the Exchange Agent shall issue and deliver to each holder of Crosstex Book-Entry Shares (x) the number of whole New Public Rangers Common Units (in the form of book-entry interests, unless the holder of such shares of Crosstex Common Stock expressly requests that such interests be delivered in certificated form) and (y) a check in an amount equal to the aggregate amount of Cash Consideration that such holder has the right to receive, in each case in respect of such shares of Crosstex Common Stock, without such holder being required to deliver a Crosstex Certificate or an executed letter of transmittal to the Exchange Agent.

(c) Distributions with Respect to Unexchanged Shares of Crosstex Common Stock. No dividends or other distributions declared or made in respect of New Public Rangers Common Units with a record date after the Crosstex Effective Time shall be paid to the holder of any unsurrendered Crosstex Certificate, unless and until the holder of such Crosstex Certificate shall surrender such Crosstex Certificate. Subject to the effect of abandoned property, escheat or other applicable Laws, following surrender of any such Crosstex Certificate, there shall be paid to the holder of whole New Public Rangers Common Units issuable in exchange therefor, without interest, (i) promptly, the amount of dividends or other distributions with a record date after the Crosstex Effective Time theretofore paid with respect to such whole New Public Rangers Common Units, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Crosstex Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such whole New Public Rangers Common Units.

(d) Further Rights in Crosstex Common Stock and New Acacia Common Stock. The Crosstex Merger Consideration issued and paid upon conversion of a share of Crosstex Common Stock in accordance with the terms of this Agreement shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to such share of Crosstex Common Stock (other than the right to receive dividends or other distributions, if any, in accordance with Section 2.3(c)). The Devon Merger Consideration issued upon conversion of a share of New Acacia Common Stock in accordance with the terms of this Agreement shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to such share of New Acacia Common Stock.

4.18 Regulatory Matters.

All natural gas pipeline systems and related facilities constituting the Midstream Business are “gathering facilities” or “intrastate pipelines” that are exempt from regulation by the FERC under the Natural Gas Act of 1938, as amended. None of the Midstream Group Entities is a “natural gas company” under the Natural Gas Act of 1938, as amended. No Midstream Group Entity has utilized its facilities to provide service as a common carrier subject to the jurisdiction of FERC under the Interstate Commerce Act as such statute is implemented by FERC pursuant to the Department of Energy Organization Act of 1977. None of the “intrastate pipelines” that are part of the Midstream Business provide transportation services pursuant to Section 311 of the Natural Gas Policy Act of 1978.

Except as would not reasonably be expected to have a Midstream Xxxxx Xxxxxxxx Adverse Effect and following the Devon Reorganization Transactions, (a) each insurance policy under which any Midstream Group Entity is an insured or otherwise the principal beneficiary of coverage related to the Midstream Business (collectively, the “Midstream Group Insurance Policies”) is in full force and effect, all premiums due thereon have been paid in full and such Midstream Group Entity is in compliance with the terms and conditions of such Midstream Group Insurance Policy; (b) no Midstream Group Entity is in breach or default under any Midstream Group Insurance Policy; and (c) no event has occurred which, with notice or lapse of time, would constitute such breach of default, or permit termination or modification, under any Midstream Group Insurance Policy.

4.20 Ownership of Crosstex Common Stock. As of the Execution Date, neither Devon nor any of its Subsidiaries beneficially owns (within the meaning of Section 13 of the Exchange Act) any of the outstanding shares of Crosstex Common Stock. No Devon Party nor any of their respective “affiliates” or “associates” (each as defined in Section 203 of the DGCL) is an “interested stockholder” (as defined in Section 203 of the DGCL) of Crosstex.

4.21 Brokers’ Fee. Except for the fee payable to Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated which shall be paid by Devon, no broker, investment banker, financial advisor or other Person is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of any Devon Party.

4.22 Information Supplied. None of the information supplied or to be supplied by the Devon Parties for inclusion or incorporation by reference in (a) the Registration Statement will, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and (b) the Proxy Statement and any amendment or supplement thereto will, at the date of mailing to stockholders and at the time of the Crosstex Stockholder Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which such statement was made, not misleading.

4.23 Matters Relating to Acquisition of the Devon Merger Consideration. Devon Gas Services has such knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risks of their investment in the Devon Merger Consideration and is capable of bearing the economic risk of such investment. Devon Gas Services is an “accredited investor” as that term is defined in Rule 501 of Regulation D (without regard to Rule 501(a)(4)) promulgated under the Securities Act. Devon Gas Services is acquiring the Devon Merger Consideration for investment for its own account and not with a view toward or for sale in connection with any distribution thereof, or with any present intention of distributing or selling the Devon Merger Consideration in violation of applicable state and federal securities laws. Devon Gas Services is not a party to any Contract or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to the Devon Merger Consideration. Devon Gas Services acknowledges and understands that (i) the acquisition of the Devon Merger Consideration has not been registered under the Securities Act in reliance on an exemption therefrom and (ii) the New Public Rangers Class B Common Units comprising the Devon Merger Consideration will, upon their sale by Devon Gas Services, unless such sale is registered under the Securities Act, be characterized as “restricted securities” under state and federal securities laws. Devon Gas Services agrees that the New Public Rangers Class B Common Units comprising the Devon Merger Consideration may not be sold, transferred, offered for sale, pledged, hypothecated or otherwise disposed of except pursuant to an effective registration statement under the Securities Act or pursuant to an available exemption from the registration requirements of the Securities Act, and in compliance with other applicable state and federal securities laws.

4.24 Investigation; No Other Representations or Warranties. Each Devon Party has undertaken such investigation as it has deemed necessary to enable it to make an informed and intelligent decision with respect to the execution, delivery and performance of this Agreement and the other Transaction Agreements to which it is a party. Devon Gas Services has had an opportunity to ask questions and receive answers from Crosstex regarding the terms and conditions of the offering of the Devon Merger Consideration and the business, properties, prospects, and financial condition of New Public Rangers. The foregoing investigation, however, does not modify the representations and warranties of Crosstex in Article III. Each of the Devon Parties acknowledges that such representations and warranties in this Agreement, the Crosstex Disclosure Letter or in the certificate referenced in Section 7.2(d) constitute the sole and exclusive representations and warranties of Crosstex to the Devon Parties in connection with the transactions contemplated by this Agreement and the other Transaction Agreements. Except for the representations and warranties contained in this Article IV, in the Devon Disclosure Letter or in the certificate referenced in Section 7.3(d), neither the Devon Parties nor any other Person makes any other express or implied representation or warranty, and Crosstex hereby disclaims reliance on any other representation or warranty, on behalf of or relating to the Devon Parties or any of their Affiliates, or their respective businesses, operations, assets, liabilities, condition (financial or otherwise) or prospects.

No amendment or supplement to the Registration Statement or the Proxy Statement shall be filed without the approval of Devon and Crosstex, which approval shall not be unreasonably withheld, conditioned or delayed; provided, however, that, with respect to documents filed by a party that are incorporated by reference in the Registration Statement or in the Proxy Statement, this right of approval shall apply only with respect to information relating to the other party and its Affiliates, their business, financial condition or results of operations or the transactions contemplated hereby; provided, further, that following a determination by the Crosstex Board to make a Crosstex Recommendation Change in accordance with Section 6.4(f), Crosstex may file an amendment or supplement to the Proxy Statement (and the related prospectus) or otherwise publicly disclose such Crosstex Recommendation Change and disseminate such information to the stockholders of Crosstex, in each case, without the consent of Devon (provided, however, that Crosstex will provide Devon a reasonable opportunity to review such amendment, supplement or public disclosure prior to filing or dissemination) in order to (i) effect a Crosstex Recommendation Change, (ii) describe the reasons for such Crosstex Recommendation Change and (iii) disclose any additional information reasonably related to the Crosstex Recommendation Change; provided, further that, in the case of clauses (ii) and (iii), if making any such disclosure would constitute a breach of the Confidentiality Agreement, Crosstex shall only be permitted to make such disclosure to the extent the Crosstex Board determines, after consultation with its outside legal advisor, that the failure to make such disclosure would result in a violation of any applicable federal securities Laws.

(b) Devon and Crosstex each agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in (i) the Registration Statement will, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and (ii) the Proxy Statement and any amendment or supplement thereto will, at the date of mailing to stockholders and at the time of the Crosstex Stockholder Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which such statement was made, not misleading.

(c) If at any time prior to the Devon Effective Time, any party discovers any information relating to Devon or Crosstex, or any of their respective Affiliates, directors or officers that should be set forth in an amendment or supplement to either the Registration Statement or the Proxy Statement so that 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 such statements were made, not misleading, the party that discovers such information shall promptly notify the other party and the parties will promptly file with the SEC an appropriate amendment or supplement describing such information and, to the extent required by Law, disseminate such information to the stockholders of Crosstex.

(d) The parties shall notify each other promptly of the receipt of any correspondence, communications or comments from the SEC or the staff of the SEC and of any request by the SEC or the staff of the SEC for amendments or supplements to the Proxy Statement or the Registration Statement or for additional information and shall supply each other with (i) copies of all correspondence and a description of all material oral discussions between it or any of its respective Representatives, on the one hand, and the SEC or the staff of the SEC, on the other hand, with respect to the Proxy Statement, the Registration Statement or the Crosstex Merger and (ii) copies of all orders of the SEC relating to the Proxy Statement or the Registration Statement.

Crosstex shall take, in accordance with the DGCL and the Organizational Documents of Crosstex, all actions reasonably necessary to call, give notice of, convene and hold a meeting of its stockholders (the “Crosstex Stockholder Meeting”) as soon as reasonably practicable after the Registration Statement is declared effective and the Proxy Statement is cleared by the SEC for the purpose of securing the Crosstex Stockholder Approval and, in any event (subject to the last sentence of this Section 6.2), within thirty (30) days of the date the Proxy Statement is mailed to the holders of Crosstex Common Stock, unless otherwise agreed by the parties; provided, however, that Crosstex shall have no obligation to hold the Crosstex Stockholder Meeting prior to sixty (60) days after the Execution Date. The Proxy Statement shall (i) state that the Crosstex Board has (x) approved this Agreement and the transactions contemplated hereby; and (y) determined that this Agreement and the transactions contemplated hereby are advisable, fair to and in the best interests of Crosstex and its stockholders; (ii) include the recommendation of the Crosstex Board that the holders of Crosstex Common Stock vote to adopt this Agreement (such recommendation

described in clause (ii), the “Crosstex Recommendation”) (except in the case of subclause (i)(y) and clause (ii) to the extent that Crosstex effects a Crosstex Recommendation Change in accordance with Section 6.4); and (iii) subject to the consent of the Crosstex Financial Advisors, include the written opinions of the Crosstex Financial Advisors, that, as of the Execution Date and based upon and subject to the assumptions, qualifications and limitations set forth in such opinion, the Crosstex Merger Consideration to be received by the holders (other than New Acacia and any direct or indirect subsidiary of New Acacia) of Crosstex Common Stock pursuant to this Agreement is fair, from a financial point of view, to such holders. Unless Crosstex effects a Crosstex Recommendation Change in accordance with Section 6.4, Crosstex shall use its reasonable best efforts to solicit from stockholders of Crosstex votes in favor of the Crosstex Stockholder Approval; provided, however, that if the Crosstex Board effects a Crosstex Recommendation Change in accordance with Section 6.4, Crosstex may cease to use such efforts. The Crosstex Board shall not effect a Crosstex Recommendation Change except pursuant to and solely as permitted by Section 6.4. Notwithstanding any Crosstex Recommendation Change, unless this Agreement has been terminated in accordance with the terms hereof, (x) this Agreement shall be submitted to the stockholders of Crosstex at the Crosstex Stockholder Meeting and nothing contained herein shall be deemed to relieve Crosstex of such obligation and (y) Crosstex shall not submit to the vote of its stockholders any Acquisition Proposal other than the Mergers. Notwithstanding anything to the contrary contained in this Agreement, Crosstex may adjourn or postpone the meeting of Crosstex’ stockholders to the extent necessary to ensure that any required supplement or amendment to the Proxy Statement is provided to Crosstex’ stockholders to provide any disclosure required by applicable Law to be provided to Crosstex’ stockholders, or, if as of the time for which the meeting of Crosstex’ stockholders is originally scheduled (as set forth in the Proxy Statement) there are insufficient shares of Crosstex Common Stock represented (either in person or by proxy) to (A) constitute a quorum necessary to conduct business at such meeting or (B) to approve the Crosstex Merger; provided, however, that, unless otherwise agreed to by the parties, no adjournment may be to a date on or after three (3) Business Days prior to the End Date.

6.3 Access to Information; Confidentiality.

(a) Subject to Section 6.3(b) and applicable Law, Crosstex will provide and will cause Crosstex’ Subsidiaries and its and their respective directors, officers, employees, accountants, consultants, legal counsel, investment bankers, advisors, and agents and other representatives (collectively, “Representatives”) to provide Devon and its authorized Representatives, during normal business hours and upon reasonable advance notice, such reasonable access to the offices, employees, customers, suppliers, properties, books and records of Crosstex and its Subsidiaries (so long as such access does not unreasonably interfere with the operations of Crosstex) as Devon may reasonably request. Subject to applicable Law, Devon will provide and will cause Devon’s Subsidiaries and its and their respective Representatives to provide Crosstex and its authorized Representatives, during normal business hours and upon reasonable advance notice, such reasonable access to the offices, employees, properties, books and records of the Midstream Group Entities (so long as such access does not unreasonably interfere with the operations of Devon or the Midstream Group Entities) as Crosstex may reasonably request. No party shall have access to personnel records of the other party or any of its Subsidiaries relating to individual performance or evaluation records, medical histories or other information that in such other party’s good faith opinion the disclosure of which could

subject such other party or any of its Subsidiaries to risk of liability. No party shall be permitted to conduct any sampling or analysis of any environmental media (including any soils, sediments, groundwater, surface water or atmosphere) or building materials at any facility of the other party or its Subsidiaries without the prior written consent of the other party, which may be granted or withheld in such other party’s sole discretion.

(b) With respect to any information disclosed pursuant to this Section 6.3, each of Devon and Crosstex shall comply with, and shall cause each of its Representatives to comply with, all of its obligations under the confidentiality agreement, dated July 19, 2013, previously executed by Devon, Crosstex and Crosstex MLP (the “Confidentiality Agreement”). No party shall be required to provide access to or disclose any information where such access or disclosure would jeopardize any attorney-client privilege of such party or any Subsidiary of such party or contravene any Contract or Law (it being agreed that the parties shall use their respective reasonable best efforts to cause such information to be provided in a manner that would not result in such jeopardy or contravention).

6.4 No Solicitation.

(a)

(i) Crosstex shall, and shall cause each of its Subsidiaries and its and their respective directors and officers, and shall use reasonable best efforts to cause its and their Representatives to, (A) immediately cease and terminate any solicitation, knowing encouragement or knowing facilitation, discussions, negotiations or other similar activities with any Persons other than Devon and its Affiliates and its and their Representatives that may be ongoing with respect to, or that may reasonably be expected to lead to, an Acquisition Proposal; and (B) immediately revoke or withdraw access of any Person other than Devon and its Affiliates and its and their Representatives to any data room (virtual or actual) containing any non-public information with respect to Crosstex or its Subsidiaries previously furnished in connection with any activities described in clause (A).

(ii) Devon shall, and shall cause each of its Subsidiaries and its and their respective directors and officers, and shall use reasonable best efforts to cause its and their Representatives to, (A) immediately cease and terminate any solicitation, knowing encouragement or knowing facilitation, discussions, negotiations or other similar activities with any Persons other than Crosstex and its Affiliates and its and their Representatives that may be ongoing with respect to, or that may reasonably be expected to lead to, a Midstream Acquisition Proposal; and (B) immediately revoke or withdraw access of any Person other than Crosstex and its Affiliates and its and their Representatives to any data room (virtual or actual) containing any non-public information with respect to the Midstream Business previously furnished in connection with any activities described in clause (A) with respect to the Midstream Business; provided, however, that in no event will Devon be required to withdraw the Midstream Registration Statement.

(b)

(i) Crosstex shall not, and shall cause each of its Subsidiaries and its and their respective directors and officers not to, and shall use reasonable best efforts to cause its and their respective Representatives not to, directly or indirectly (A) solicit, initiate, knowingly facilitate or knowingly encourage (including by way of furnishing information) any inquiries regarding, or the making or submission of any proposal or offer that constitutes, or would reasonably be expected to lead to, an Acquisition Proposal, (B) conduct or engage in any discussions or negotiations with, disclose any information or data relating to Crosstex or any of its Subsidiaries to, or afford access to the business, properties, assets, books or records of Crosstex or any of its Subsidiaries to, or knowingly take any other action to assist, facilitate or cooperate with any effort by any third party with respect to, or that is seeking to make or has made, any Acquisition Proposal, or (C) enter into any agreement, including any agreement in principle, letter of intent, term sheet, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other Contract relating to any Acquisition Proposal (other than an Acceptable Confidentiality Agreement in circumstances contemplated in Section 6.4(c)).

(ii) Devon shall not, and shall cause each of its Subsidiaries and its and their respective directors and officers not to, and shall use reasonable best efforts to cause its and their respective Representatives not to, directly or indirectly (A) solicit, initiate, knowingly facilitate or knowingly encourage (including by way of furnishing information) any inquiries regarding, or the making or submission of any proposal or offer that constitutes, or would reasonably be expected to lead to, a Midstream Acquisition Proposal, (B) conduct or engage in any discussions or negotiations with, disclose any information or data relating to the Midstream Business to, or afford access to the business, properties, assets, books or records of the Midstream Business to, or knowingly take any other action to assist, facilitate or cooperate with any effort by any third party with respect to, or that is seeking to make or has made, any Midstream Acquisition Proposal, or (C) enter into any agreement, including any agreement in principle, letter of intent, term sheet, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other Contract relating to any Midstream Acquisition Proposal.

(c) Notwithstanding anything in this Agreement to the contrary, Crosstex and its Subsidiaries and its and their Representatives may take the actions described in Section 6.4(b)(i)(B) with respect to a third party prior to, but not after, the receipt of the Crosstex Stockholder Approval, if (i) Crosstex (A) has not materially breached this Section 6.4, and (B) receives after the Execution Date a bona fide, written Acquisition Proposal from such third party that did not result from any breach of this Section 6.4 and (ii) before taking any such actions, the Crosstex Board (or the Special Committee thereof) determines in good faith, after consultation with its financial advisor and outside legal counsel, that (A) failure to take such action would be inconsistent with the fiduciary duties of Crosstex’ directors under applicable Law and (B) such Acquisition Proposal either constitutes a Superior Proposal or would be reasonably likely to lead to a Superior Proposal; provided; however, that (1) Crosstex shall not deliver any information or data to such third party or afford such third party any access prior to entering into an Acceptable

Confidentiality Agreement with such third party and (2) Crosstex shall, as promptly as practicable (and in any event within twenty-four (24) hours), provide to Devon a copy of such executed Acceptable Confidentiality Agreement. Crosstex agrees that it shall substantially concurrently with delivery to any third party provide to Devon any information concerning Crosstex or its Subsidiaries that is provided to any third party in connection with any Acquisition Proposal which information was not previously provided to Devon.

(d)

(i) Crosstex shall, as promptly as practicable (and in any event within twenty-four (24) hours after receipt), advise Devon orally and in writing of any Acquisition Proposal received by Crosstex, any of its Subsidiaries or any of its or their Representatives from any Person, or any inquiry, discussions or negotiations with respect to or that is related to any Acquisition Proposal or by any party under circumstances reasonably expected to be related to the evaluation or making of any Acquisition Proposal, and the material terms and conditions of such request, Acquisition Proposal, inquiry, discussions or negotiations, and Crosstex shall, as promptly as practicable (and in any event within twenty-four (24) hours after receipt), provide to Devon copies of any written materials received in connection with any of the foregoing, and the identity of the Person making any such request, Acquisition Proposal or inquiry or with whom any discussions or negotiations are taking place. Crosstex shall keep Devon reasonably informed of any material developments regarding the material terms and conditions of any Acquisition Proposal on a reasonably current basis (and in any event within twenty-four (24) hours). Crosstex agrees that it and its Subsidiaries will not enter into any confidentiality or other agreement with any Person subsequent to the Execution Date that prohibits Crosstex from providing any information to Devon in accordance with this Section 6.4.

(ii) Devon shall, as promptly as practicable (and in any event within twenty-four (24) hours after receipt), advise Crosstex orally and in writing of any Midstream Acquisition Proposal received by Devon, any of its Subsidiaries or any of its or their Representatives from any Person, or any inquiry, request for information, discussions or negotiations with respect to or that is related to any Midstream Acquisition Proposal or by any party under circumstances reasonably expected to be related to the evaluation or making of any Midstream Acquisition Proposal, and the material terms and conditions of such request, Midstream Acquisition Proposal, inquiry, discussions or negotiations and Crosstex shall, as promptly as practicable (and in any event within twenty-four (24) hours after receipt), provide to Crosstex copies of any written materials received in connection with any of the foregoing and the identity of the Person making such a request, Midstream Acquisition Proposal or inquiry or with whom any discussions or negotiations are taking place. Devon shall keep Crosstex reasonably informed of any material developments, discussions or negotiations regarding the material terms and conditions of any Midstream Acquisition Proposal on a reasonably current basis (and in any event within twenty-four (24) hours). Devon agrees that it and its Subsidiaries will not enter into any confidentiality or other agreement with any Person subsequent to the Execution Date that prohibits Devon from providing any information to Crosstex in accordance with this Section 6.4.

(e) Neither the Crosstex Board nor any committee thereof will (i) fail to make, change, qualify, withhold, withdraw or modify, or publicly propose to change, qualify, withhold, withdraw or modify the Crosstex Recommendation; (ii) fail to recommend against acceptance of any tender offer or exchange offer for the shares of Crosstex Common Stock within ten (10) Business Days after commencement of any such offer; (iii) adopt, approve or recommend, or publicly propose to approve or recommend an Acquisition Proposal; (iv) make any public statement that is materially inconsistent with the Crosstex Recommendation; or (v) publicly resolve or agree (whether or not publicly) to take any of the actions described in subclauses (i) through (v) above (actions described in subclauses (i) through (v) being referred to as a “Crosstex Recommendation Change”).

(f) Notwithstanding anything in this Agreement to the contrary, prior to, but not after, receipt of the Crosstex Stockholder Approval, the Crosstex Board (or the Special Committee thereof) may (A) make a Crosstex Recommendation Change in respect of an Acquisition Proposal or terminate this Agreement in accordance with Section 8.1(g) in order to enter into a definitive written agreement with respect to a Superior Proposal, in each case, if, prior to taking such action, the Crosstex Board (or the Special Committee thereof) has determined in good faith, after consultation with its financial advisor and outside legal counsel, that such Acquisition Proposal constitutes a Superior Proposal and the failure to make a Crosstex Recommendation Change or terminate this Agreement in accordance with Section 8.1(g) would be inconsistent with the fiduciary duties of the directors of Crosstex under applicable Law, or (B) make a Crosstex Recommendation Change if, prior to taking such action, the Crosstex Board (or the Special Committee thereof) has determined in good faith, after consultation with its financial advisor and outside legal counsel, that in response to an Intervening Event and in the absence of an Acquisition Proposal, failure to make a Crosstex Recommendation Change in response to such Intervening Event would be inconsistent with the fiduciary duties of the directors of Crosstex under applicable Law. The Crosstex Board (or the Special Committee thereof) shall not make a Crosstex Recommendation Change pursuant to Section 6.4(f)(A) or terminate this Agreement in accordance with Section 8.1(g) unless prior to taking such action (i) Crosstex has given Devon at least three (3) Business Days prior written notice of its intention to make a Crosstex Recommendation Change or terminate this Agreement in accordance with Section 8.1(g) (which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the Person making such Superior Proposal)) and has contemporaneously provided to Devon a copy of any proposed transaction agreements related to such Superior Proposal, (ii) Crosstex has negotiated, and has caused its Representatives to negotiate, in good faith with Devon during such notice period to enable Devon to revise the terms of this Agreement such that it would cause such Superior Proposal to no longer constitute a Superior Proposal, (iii) following the end of such notice period, the Crosstex Board shall have considered in good faith any changes to this Agreement proposed in writing by Devon, and shall have determined in good faith, after consultation with its financial advisor and outside legal counsel, that notwithstanding such proposed changes, the third-party proposal remains a Superior Proposal and failure to make a Crosstex Recommendation Change or terminate this Agreement in accordance with Section 8.1(g), as applicable, in response to the Superior Proposal would be inconsistent with the fiduciary duties of the Crosstex directors under applicable Law, and (iv) Crosstex has complied in all material respects with its obligations under this Section 6.4. Any amendment to the financial terms or other material terms of a Superior Proposal after delivery of a notice in respect of such Superior Proposal shall require delivery of another notice and shall

commence a new notice period in respect of such Superior Proposal pursuant to this Section 6.4(f) except that, commencing with the third notice period hereunder with respect to a Superior Proposal made by a particular Person, the notice period shall be one (1) Business Day (rather than the three (3) Business Days contemplated by clause (i) above). The Crosstex Board shall not make a Crosstex Recommendation Change pursuant to Section 6.4(f)(B) unless prior to taking such action, (w) Crosstex has given Devon at least three (3) Business Days prior written notice of its intention to make a Crosstex Recommendation Change (which notice shall provide a detailed description of the Intervening Event), (x) Crosstex has negotiated, and has caused its Representatives to negotiate, in good faith with Devon during such notice period to enable Devon to revise the terms of this Agreement in such a manner or take other actions that would obviate the need for taking such action as a result of such Intervening Event, (y) following the end of such notice period, the Crosstex Board shall have considered in good faith any changes to this Agreement or other actions proposed in writing by Devon, and shall have determined in good faith, after consultation with its financial advisor and outside legal counsel, that notwithstanding such proposed changes or other actions, failure to make a Crosstex Recommendation Change in response to an Intervening Event would be inconsistent with the directors’ fiduciary duties under applicable Law, and (z) Crosstex has complied in all material respects with its obligations under this Section 6.4. No Crosstex Recommendation Change shall change the approval of this Agreement for purposes of Section 251 of the DGCL, and no Crosstex Recommendation Change shall have the effect of causing any state (including Delaware) corporate Takeover Law or other similar statute to be applicable to the transactions contemplated by this Agreement (including the Mergers).

(g) Nothing in this Agreement shall prohibit the Crosstex Board or Devon from complying with its disclosure obligations under U.S. federal or state Law, including (i) taking and disclosing to Crosstex stockholders a position contemplated by Rule 14e-2(a) and Rule 14d-9 or Item 1012(a) of Regulation M-A under the Exchange Act, or (ii) making any “stop-look-and-listen” communication to the Crosstex stockholders or Devon stockholders, as applicable, pursuant to Rule 14d-9(f) under the Exchange Act; provided, however, that in no event shall any such requirement affect, eliminate or modify the obligations of Crosstex or Devon, as applicable, under, or the effect of any such actions under, this Section 6.4; and provided, further, that any such disclosure made by the Crosstex Board will be deemed to be a Crosstex Recommendation Change unless the Crosstex Board publicly reaffirms the Crosstex Recommendation in such statement or in connection with such action.

(h) Crosstex shall promptly inform its Representatives who have been engaged or are otherwise providing assistance in connection with the transactions contemplated by this Agreement of Crosstex’ obligations under this Section 6.4. Without limiting the generality of the foregoing, Crosstex acknowledges and agrees that any violation of the restrictions set forth in this Section 6.4 by any Representative of Crosstex or its Subsidiaries shall be deemed to be a breach of this Section 6.4 by Crosstex.

(i) Definitions of Acquisition Proposal, Intervening Event; Midstream Acquisition Proposal and Superior Proposal. For purposes of this Agreement:

“Acquisition Proposal” means any offer, proposal, inquiry or indication of interest relating to any transaction or series of related transactions (other than the transactions

contemplated by this Agreement) from any third party involving: (a) a merger, reorganization, share exchange, consolidation, business combination, recapitalization, dissolution, liquidation or similar transaction involving Crosstex or any of its Subsidiaries whose assets, taken together, constitute fifteen percent (15%) or more of Crosstex’ consolidated assets, (b) any purchase (including any lease, long term supply agreement, mortgage, pledge or other arrangement having similar economic effect), directly or indirectly, in any manner of any business or assets (including equity securities or other interest in one or more Subsidiaries) that constitute fifteen percent (15%) or more of the consolidated assets of Crosstex or that generate fifteen percent (15%) or more of Crosstex’ consolidated revenues or net income, or (c) the acquisition, directly or indirectly, of beneficial ownership or control of any securities of Crosstex after which any person or group would own securities representing fifteen percent (15%) or more of the total voting power of any class of Crosstex’ securities (or that are exchangeable for or convertible into voting securities having such voting power).

“Intervening Event” means a material Event that did not exist or was not known to the Crosstex Board or the Special Committee thereof on the Execution Date (or if known, the consequences of which were not known or reasonably foreseeable by the Crosstex Board or the Special Committee thereof as of the Execution Date), which Event, or any material consequences thereof, becomes known to the Crosstex Board or the Special Committee thereof prior to receipt of the Crosstex Stockholder Approval; provided; however, that in no event shall the receipt, existence, potential for or terms of an Acquisition Proposal or any matter relating thereto or consequence thereof constitute an Intervening Event.

“Midstream Acquisition Proposal” means any offer, proposal, inquiry or indication of interest relating to any transaction or series of related transactions (other than the transactions contemplated by this Agreement) from any third party involving: (a) a merger, reorganization, share exchange, consolidation, business combination, recapitalization, dissolution, liquidation or similar transaction involving any Devon Midstream Entity whose assets, taken together, constitute fifteen percent (15%) or more of the consolidated assets of the Devon Midstream Entities, (b) any purchase (including any lease, long term supply agreement, mortgage, pledge or other arrangement having similar economic effect), directly or indirectly, in any manner of any business or assets (including equity securities or other interest in one or more Subsidiaries) that constitute fifteen percent (15%) or more of the consolidated assets of the Devon Midstream Entities or that generate fifteen percent (15%) or more of the consolidated revenues or net income of the Devon Midstream Entities, or (c) the acquisition, directly or indirectly, of beneficial ownership or control of any securities of any Devon Midstream Entity after which any person or group would own securities representing fifteen percent (15%) or more of the total voting power of any class of securities of any Devon Midstream Entity (or that are exchangeable for or convertible into voting securities having such voting power). For purpose of this definition, “Devon Midstream Entity” means any Person that is or, upon consummation of the Devon Reorganization Transactions, will become, a Midstream Group Entity; provided, however, that a Midstream Acquisition Proposal shall not include any offer, proposal, inquiry, or indication of interest relating to any transaction described in clauses (a), (b) or (c) above on terms which do not materially interfere with the consummation of the transactions contemplated by this Agreement and the Contribution Agreement.

“Superior Proposal” means a bona fide written Acquisition Proposal, on its most recently amended or modified terms, if amended or modified (except that references in the definition of “Acquisition Proposal” to “15%” shall be replaced with 50%) made by a third party, that the Crosstex Board (or the Special Committee thereof) determines in good faith (after consultation with its financial advisor and outside legal counsel) (i) would be, if consummated, more favorable to Crosstex’ stockholders from a financial point of view than the Mergers (taking into account all of the terms and conditions of such proposal and this Agreement (including any changes to the terms of this Agreement proposed by Devon in response to such offer or otherwise) and relevant legal, financial and regulatory aspects of the proposal and the conditions for completion of such proposal; and (ii) is reasonably likely to be consummated, taking into account the financial, legal, regulatory and other aspects of such proposal.

6.5 Efforts to Consummate; Notification.

(a) Subject to the terms and conditions of this Agreement, each of Devon and Crosstex will use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable Law to consummate the Mergers and the other transactions contemplated by this Agreement including using reasonable best efforts to (i) cause the conditions precedent set forth in Article VII to be satisfied, (ii) obtain all necessary waivers, consents, approvals, permits, orders or authorizations (including the expiration or termination of any waiting periods) from Governmental Entities and the making of all necessary registrations, declarations and filings (including registrations, declarations and filings with Governmental Entities, if any) and take all steps as may be necessary to avoid, or to have terminated, if begun, any Proceeding by any Governmental Entity, (iii) obtain all necessary waivers, consents, approvals, permits, orders or authorizations from third parties, (iv) defend any Proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby, including seeking to avoid the entry of, or to have reversed, terminated, lifted or vacated, any stay, temporary restraining order or other injunctive relief or order entered by any Governmental Entity that could prevent or delay the Mergers or the consummation of the transactions contemplated hereby and (v) execute and deliver additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement. In furtherance and not in limitation of the foregoing, Crosstex agrees not to extend any waiting period under HSR Act or enter into any agreement with any Governmental Entity not to consummate the transaction contemplated by this Agreement, except with the prior written consent of Devon.

(b) In furtherance and not in limitation of the foregoing, Devon and Crosstex shall (i) make or cause to be made the registrations, declarations and filings required of such party under the U.S. Xxxx-Xxxxx-Xxxxxx Antitrust Improvements Act of 1976, as amended (the “HSR Act”) with respect to the transactions contemplated by this Agreement as promptly as reasonably practicable and advisable after the Execution Date and in no event later than fifteen (15) Business Days after the Execution Date, (ii) furnish to the other party as promptly as reasonably practicable all information required for any application or other filing to be made by the other

party pursuant to any applicable Law in connection with the transactions contemplated by this Agreement, (iii) respond as promptly as reasonably practicable to any inquiries received from, and supply as promptly as reasonably practicable any additional information or documentation that may be requested by, the Antitrust Division of the U.S. Department of Justice (the “DOJ”), the Federal Trade Commission (“FTC”) or by any other Governmental Entity in respect of such registrations, declarations and filings or such transactions, (iv) promptly notify the other party of any material communication between that party and the FTC, the DOJ, or any other Governmental Entity and of any material communication received or given in connection with any proceeding by a private party, in each case regarding any of the transactions contemplated hereby (including any communication relating to the antitrust merits, any potential remedies, commitments or undertakings, the timing of any waivers, consents, approvals, Permits, orders or authorizations (including the expiration or termination of any waiting periods), or any agreement regarding the timing of consummation of the Mergers), (v) subject to applicable Law, discuss with and permit the other party (and its counsel) to review in advance, and consider in good faith the other party’s reasonable comments in connection with, any proposed filing or communication to the FTC, the DOJ, or any other Governmental Entity or, in connection with any proceeding by a private party to any other Person, relating to any Regulatory Law or any investigation or other Proceeding pursuant to any Regulatory Law in connection with the Mergers or the other transactions contemplated by this Agreement, (vi) not initiate or participate or agree to participate in any substantive meeting, telephone call or discussion (including any meeting, telephone call or discussion relating to the antitrust merits, any potential remedies, commitments or undertakings, the timing of any waivers, consents, approvals, Permits, orders or authorizations (including the expiration or termination of any waiting periods), and any agreement regarding the timing of consummation of the Mergers) with the FTC, the DOJ or any other Governmental Entity in respect of any filings, investigation or inquiry relating to any Regulatory Law or any investigation or other Proceeding pursuant to any Regulatory Law in connection with this Agreement or the Mergers unless it consults with the other party in advance and, to the extent permitted by such Governmental Entity, gives the other party the opportunity to attend and participate in such meeting, telephone call or discussion, (vii) furnish the other party promptly with copies of all correspondence, filings and communications relating to any Regulatory Law or any investigation or other Proceeding pursuant to any Regulatory Law between them and their Affiliates and their respective Representatives on the one hand, and the FTC, the DOJ or any other Governmental Entity or members of their respective staffs on the other hand, with respect to this Agreement and the Mergers, and (viii) act in good faith and reasonably cooperate with the other party in connection with any such registrations, declarations and filings and in connection with resolving any investigation or other inquiry of any such agency or other Governmental Entity under the HSR Act or any other Regulatory Law with respect to any such registration, declaration and filing or any such transaction; provided, however, that in the event of any disagreement concerning any such filing, submission, investigation, Proceeding, communication or meeting, the determination of Devon shall be final and conclusive; provided, further, that nothing in this Agreement shall prevent a party from responding to or complying with a subpoena or other legal process required by Law or submitting documents or factual information in response therefor. Devon and Crosstex may, as each deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other under this Section 6.5(b) as “Antitrust Counsel Only Material.” Such materials and the information contained therein shall be given only to the outside antitrust counsel of the recipient and will not

be disclosed by such outside counsel to employees, officers or directors of the recipient unless express permission is obtained in advance from the source of the materials (Devon or Crosstex, as the case may be) or its legal counsel. Notwithstanding anything to the contrary in this Section 6.5(b), materials provided to the other party or its outside counsel may be redacted to remove references concerning the valuation of Crosstex and its Subsidiaries or New Acacia and its Subsidiaries.

(c) Devon shall have the right, but not the obligation, to agree to or take any action that would result in making or offering proposals, remedies, commitments or undertakings, executing or carrying out agreements (including consent decrees) or submitting to Laws (i) providing for the license, sale, divestiture or other disposition or holding separate (through the establishment of trust or otherwise) of any business, assets, categories of assets, or products of Devon, Crosstex or their respective Subsidiaries or the holding separate of the capital stock or other Equity Interests of a Subsidiary of Crosstex or Devon, (ii) otherwise imposing or seeking to impose any limitation on Devon, Crosstex or any of their respective Subsidiaries’ freedom of action with respect to, or their ability to retain, any of the businesses, assets, categories of assets, or products of Devon, Crosstex, New Public Rangers or any of their respective Subsidiaries or (iii) entering into, modifying or terminating any relationship, contract or arrangement between Devon, Crosstex, New Public Rangers or any of their respective Subsidiaries on the one hand and any third party on the other hand (any matter referenced in the foregoing clauses (i)–(iii) being a “Regulatory Divestiture”); provided, however that (A) the consummation of any such Regulatory Divestiture shall be contingent on the consummation of the Mergers, (B) Devon may not agree to or effect any Regulatory Divestiture that would be material to the Midstream Business and Crosstex, taken as a whole, without the prior written consent of Crosstex and (C) the net proceeds of any such Regulatory Divestiture with respect to the business, assets, categories of assets or products of the Midstream Business shall be contributed to the applicable Midstream Group Entity immediately prior to the Devon Effective Time.

6.6 Certain Notices. From and after the Execution Date until the earlier to occur of (a) the Closing Date and (b) the termination of this Agreement pursuant to Section 8.1, each of Devon and Crosstex shall promptly notify the other of (i) the occurrence, or non-occurrence, of any Event that would be likely to cause any condition to the obligations of either party to effect the Mergers and the other transactions contemplated by this Agreement not to be satisfied, or (ii) the failure of Devon or Crosstex to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it pursuant to this Agreement that would reasonably be expected to result in any condition to the obligations of either party to effect the Mergers and the other transactions contemplated by this Agreement not to be satisfied; provided, however, that the delivery of any notice pursuant to this Section 6.6 shall not cure the inaccuracy of any representation or warranty, the failure to comply with any covenant, the failure to meet any condition or otherwise limit or affect the remedies available hereunder to the party receiving such notice; provided, further, that the failure to comply with this Section 6.6 shall not result in the failure of any of the conditions to the Closing in Article VII to be satisfied, or give rise to any right to terminate this Agreement under Section 8.1, if the underlying Event would not in and of itself give rise to such failure or right.

6.7 Public Announcements. The initial press release with respect to this Agreement and the transactions contemplated hereby shall be a release mutually agreed upon by Devon and

Crosstex. Thereafter, except in connection with a Crosstex Recommendation Change in accordance with Section 6.4 (in which case Crosstex will, to the extent practicable, promptly inform Devon in advance of the substance and timing of the release or statement), Devon and Crosstex shall consult with and obtain the approval of the other party (such approval not to be unreasonably withheld, conditioned or delayed) before issuing any other press release or other public statements with respect to the Mergers or this Agreement, to the extent they have not been previously issued or disclosed and shall not issue any such other press release prior to such consultation, except as may be required by applicable Law or any listing agreement related to the trading of the shares of either party on any securities exchange, in which case the party proposing to issue such press release or make such public announcement shall use reasonable best efforts to consult in good faith with the other party before issuing any such press release or making any such public announcement. Notwithstanding the foregoing, the parties may respond to inquiries from securities analysts, and the news media and make such oral and written public statements, releases or announcements without complying with the preceding sentence if the substance of such statements, releases or announcements was in any prior press release or public statement made by a party in accordance with this Section 6.7; provided, however, that such responses shall be in compliance with applicable securities Laws.

6.8 Indemnification of Directors and Officers.

(a) From and after the Crosstex Effective Time, New Public Rangers shall indemnify and hold harmless (and advance funds in respect of each of the foregoing), in the same manner as provided by Crosstex or any Subsidiary of Crosstex immediately prior to the Execution Date, each present and former director, manager, officer and employee of Crosstex and its Subsidiaries and each person who served as a director, manager, officer, member, trustee or fiduciary of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise if such service was at the request of Crosstex or any of its Subsidiaries (such persons, in all of their capacities, together with their respective heirs, executors or administrators, collectively, the “Indemnified Parties”), against any costs or expenses (including reasonable attorneys’ fees and expenses and disbursements), judgments, fines, losses, claims, damages or liabilities incurred in connection with any Proceeding, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that such Indemnified Party is or was a director, manager, officer or employee of Crosstex or any of its Subsidiaries or a director, manager, officer, member, trustee or fiduciary of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise if such service was at the request of Crosstex or any of its Subsidiaries, whether asserted or claimed prior to, at or after the Crosstex Effective Time (including with respect to acts or omissions by directors, managers or officers of Crosstex or its Subsidiaries in their capacities as such arising in connection with the transactions contemplated by this Agreement), and shall provide advancement of expenses to the Indemnified Parties, in all such cases to the same extent that such persons are indemnified or have the right to advancement of expenses as of the Execution Date by Crosstex pursuant to Crosstex’ Organizational Documents and indemnification agreements, if any, or by any one of Crosstex’ Subsidiaries pursuant to such Subsidiary’s Organizational Documents and indemnification agreements of any Subsidiary of Crosstex, if any, in existence on the Execution Date.

(b) For six (6) years after the Crosstex Effective Time, New Public Rangers shall maintain in effect for the benefit of the Indemnified Parties an insurance and indemnification

policy with an insurer with the same or better credit rating as the current carrier for Crosstex that provides coverage for acts or omissions occurring prior to the Crosstex Effective Time (the “D&O Insurance”) covering each such person covered by the officers’ and directors’ liability insurance policy of Crosstex on terms with respect to coverage and in amounts no less favorable in the aggregate than those of Crosstex’ directors’ and officers’ insurance policy in effect on the Execution Date; provided, however, that New Public Rangers shall not be required to pay an annual premium for the D&O Insurance in excess of 250% of the annual premium currently paid by Crosstex for such coverage; and provided, further, however, that if any annual premium for such insurance coverage exceeds 250% of such annual premium, New Public Rangers shall obtain as much coverage as reasonably practicable for a cost not exceeding such amount. New Public Rangers’ obligations under this Section 6.8(b) may be satisfied by New Public Rangers, or, with the approval (such approval not to be unreasonably withheld) of Devon, Crosstex, purchasing a “tail” policy from an insurer with substantially the same or better credit rating as the current carrier for Crosstex’ existing directors’ and officers’ insurance policy, which (i) has an effective term of six (6) years from the Crosstex Effective Time, (ii) covers each person covered by Crosstex’ directors’ and officers’ insurance policy in effect on the Execution Date or at the Crosstex Effective Time for actions and omissions occurring prior to the Crosstex Effective Time, and (iii) contains terms that are no less favorable in the aggregate than those of Crosstex’ directors’ and officers’ insurance policy in effect on the Execution Date. If such “tail” policy has been obtained by Crosstex prior to the Crosstex Effective Time, New Public Rangers shall cause such policy to be maintained in full force and effect, for its full term, and cause all obligations thereunder to be honored by New Public Rangers.

(c) The provisions of this Section 6.8 are (i) intended to be for the benefit of, and will be enforceable by, each Indemnified Party and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by Contract or otherwise. New Public Rangers shall pay all reasonable out-of-pocket expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in enforcing the indemnity obligations provided in this Section 6.8 unless it is ultimately determined that such Indemnified Party is not entitled to such indemnity.

(d) If New Public Rangers, or any of its 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 each case, proper provision shall be made so that the successors and assigns of New Public Rangers honor the indemnification obligations set forth in this Section 6.8.

6.9 Employee Benefits.

(a) Post-closing Employment. On the Closing Date, Devon shall, or shall cause its Affiliates to, make available for hiring by New Public Rangers or its Subsidiaries all employees (other than corporate general and administrative personnel) who dedicate their full employment services to the Midstream Businesses as well as such additional employees as shall be mutually agreed by Devon and Crosstex between the Execution Date and the Closing Date (each such employee a “Transferring Employee”) and Crosstex shall, or shall cause its Affiliates to, make offers of at-will employment within a reasonable time prior to the Closing Date to each such

Transferring Employee with such employment to be effective as of the Closing Date (to the extent such offers of employment are accepted); provided, however, that no individual who is collecting payments under any long-term disability plan or short-term disability plan of Devon or its Affiliates as of the Closing Date (a “Disability Employee”) shall be a “Transferring Employee”. Each employment offer shall be for a position that has duties that are materially consistent with the current position held by such Transferring Employee immediately prior to the Closing Date and will be made on terms and conditions sufficient to avoid statutory, contractual, common law or other severance obligations. In connection with the foregoing offers of employment, Crosstex shall grant equity awards in the amounts and to such Transferring Employees as shall be mutually determined by Devon and Crosstex prior to the Closing Date. Notwithstanding any provision herein to the contrary, Crosstex and its Affiliates shall have no obligation to hire any Disability Employee who does not return to bona fide service with Devon or an Affiliate thereof prior to the first anniversary of the Closing Date, unless otherwise required by applicable Law. To the extent a Disability Employee returns to bona fide service with Devon or an Affiliate thereof prior to the first anniversary of the Closing Date, Devon or such Affiliate shall provide Crosstex with written notice thereof as soon as administratively practicable. Upon receipt of such notice, Crosstex or an Affiliate thereof shall promptly engage in employment offer and hiring procedures similar to those set forth in this Section 6.9(a) with respect to such Disability Employee.

(b) Employee Benefits. Crosstex shall, or shall cause its Affiliates to, provide to each Transferring Employee (i) for a period of twelve (12) months after such Transferring Employee commences employment with Crosstex or an Affiliate thereof under Section 6.9(a), a base salary or wages and bonus opportunities that are no less favorable than those provided by Devon or its Affiliates immediately prior to the Closing Date (or that would have reasonably been provided immediately prior to the Closing Date with respect to a Disability Employee who becomes a Transferring Employee) and (ii) other employee benefits, plans, programs and arrangements that are substantially comparable in the aggregate to those provided to similarly situated employees at Crosstex or its Affiliates under the Crosstex Benefit Plans as in effect on the Closing Date. Each Transferring Employee shall, effective as of the date the Transferring Employee commences employment with Crosstex or an Affiliate hereof under Section 6.9(a), cease to be employed by Devon and its Affiliates and shall cease all active participation in and accrual of benefits under the Midstream Group Benefit Plans, except as otherwise provided under the plan or agreement governing the applicable benefit or required by Law.

(i) Crosstex or its Affiliates shall bear any costs related to, and shall indemnify and hold harmless Devon or any of its Affiliates from and against, any claims made by any Midstream Group Employee for any statutory, contractual or common law severance or separation benefits and other legally mandated payment obligations (including the employer portion of any employment taxes, together with any compensation payable during any mandatory termination notice period related thereto) (collectively, the “Separation Benefits”), in each case, arising out of or in connection with the failure of Crosstex or its Affiliates to make offers of employment of any Midstream Group Employee in accordance with this Agreement and as required by applicable Law.

(ii) Section 6.9(c)(ii) of the Devon Disclosure Letter lists the plans and programs in which the Transferred Employees participate immediately prior to the Effective Date. The Crosstex Entities shall, or shall cause their Affiliates to, provide each Transferring Employee whose employment is terminated within twelve (12) months following the Closing Date with severance and other separation benefits substantially the same as the severance and other separation benefits, if any, available to such Transferring Employee by the Midstream Group Entities as in effect prior to the Closing Date.

(d) Allocation of Employment Liabilities. Except with respect to any liabilities that transfer to Crosstex or its Affiliates pursuant to applicable Law or as otherwise specifically provided in this Agreement, Devon or any of its Affiliates shall retain liability and responsibility for all employment and employee-benefit related liabilities, obligations, claims or losses that arise as a result of an event or events that relate to a Transferring Employee (or any dependent or beneficiary of any Transferring Employee) and that occur prior to the effective time of such Transferring Employee’s employment with Crosstex or an Affiliate thereof. Except with respect to any liabilities that transfer to Devon or its Affiliates pursuant to applicable Law or as otherwise specifically provided in this Agreement, Crosstex or any of its Affiliates shall retain liability and responsibility for all employment and employee-benefit related liabilities, obligations, claims or losses that arise as a result of an event or events that relate to the Transferring Employees (or any dependent or beneficiary of any Transferring Employee) and that occur on or after the effective time of such Transferring Employee’s employment with Crosstex or an Affiliate thereof.

(e) Credit for Prior Service. Crosstex and its Affiliates agree that from and after the Closing Date, the Transferring Employees shall be credited with their length of service with the Midstream Group Entities for purposes of vesting, eligibility and level of benefits under all employee benefit plans, equity or equity-based awards, bonus plans or agreements, or other programs and policies (other than employee pension plans subject to Title IV of ERISA) in which the Transferring Employees may participate in or be covered under from and after the Closing Date. Such pre-Closing Date service credit shall also be taken into account for purposes of benefit computation under all severance or unemployment compensation plans or policies that may apply to the Transferring Employees after the Closing Date.

(f) Vacation Time. Devon shall, or shall cause its Affiliates to, pay an amount to each Transferring Employee as soon as practical, but in no event later than sixty (60) days following the Closing Date or such earlier date as required by applicable Law, equal to the value of the unused paid time off accrued as of the Closing Date by each Transferring Employee under the paid time off programs of Devon or its Affiliates. As such, no vacation days, sick leave, or paid time off accrued under the plans or programs of Devon or its Affiliates prior to the Closing Date shall roll-over or be credited to the Transferring Employees under the paid time off plans of Crosstex or its Affiliates. Accruals of paid time off under the programs of Crosstex or its Affiliates shall begin following the Closing Date and professional service credit will be provided to both exempt and non-exempt employees under such plans.

(g) 401(k) Plans. In the event that a Transferring Employee makes a voluntary election pursuant to Section 401(a)(31) of the Code to roll over his or her account balance in a tax qualified defined contribution plan sponsored by Devon or its Affiliates to a tax-qualified

defined contribution plan sponsored by Crosstex or its Affiliates in which such Transferring Employee is eligible to participate, Crosstex agrees, or shall cause its Affiliates to agree, to take commercially reasonable steps to cause such tax-qualified defined contribution plan to accept such rollover in cash, but only to the extent permitted by applicable Law and the terms of such Crosstex Entity plan.

(h) Terms of Coverage. To the extent that any Transferring Employee becomes covered under a Crosstex Benefit Plan of Crosstex or its Affiliate, any restrictions on coverage for pre-existing conditions requirements for evidence of insurability or eligibility waiting periods under such plans will be waived for such Transferring Employee, to the extent such waiver is permitted under the applicable Crosstex Benefit Plan. Crosstex or its Affiliates shall use reasonable best efforts to provide that each Transferring Employee who becomes covered under a Crosstex Benefit Plan that is a group health plan (including a “group health plan” as defined in Section 5000(b)(1) of the Code) shall receive credit for those sums paid in the current year under the corresponding Midstream Group Benefit Plan as deductibles, coinsurance and co-payments, towards any deductible and/or out-of-pocket maximum that may apply under such Crosstex Benefit Plan.

(i) No Assumption of Midstream Group Benefit Plan. Crosstex and its Affiliates shall not assume any Midstream Group Benefit Plan or any similar arrangement of Devon or its Affiliates, and Devon and its Affiliates shall take all necessary actions to ensure that no such Midstream Group Benefit Plan or any similar arrangement is assumed by Crosstex or an Affiliate thereof.

(j) Additional Information. The parties agree to furnish each other with such information concerning employees and employee benefit plans, and to take all such other action, as is necessary and appropriate to effect the transactions contemplated by this Section 6.9, subject to any applicable restrictions under the Health Insurance Portability and Accountability Act of 1996, as amended, and other federal and state privacy Laws. Where any required information is in the possession of third parties controlled by Crosstex or Devon, such as insurers or trustees, Crosstex or Devon, as applicable, shall use reasonable efforts to cause those third parties to cooperate in providing any such information to the other party.

(k) No Third Party Beneficiaries. The provisions of this Section 6.9 are solely for the benefit of the respective Parties to this Agreement and nothing in this Section 6.9, express or implied, shall confer upon any Midstream Group Employee, or legal representative or beneficiary thereof, any rights or remedies, including any right to employment or continued employment for any specified period, or compensation or benefits of any nature or kind whatsoever under this Agreement. Nothing in this Section 6.9, express or implied, shall be (i) deemed an amendment of any plan providing benefits to any Midstream Group Employee, or (ii) construed to prevent Crosstex or its Affiliates from terminating or modifying to any extent or in any respect any benefit plan that they may establish or maintain.

(l) Waiver of Acceleration. Crosstex and its Affiliates shall use their reasonable best efforts to obtain executed and enforceable Change of Control Waivers from all executives of Crosstex set forth on Section 6.9(l) of the Crosstex Disclosure Letter.

6.10 Section 16(b) Matters. Prior to the Crosstex Effective Time, Devon and Crosstex shall take all such steps as may be required to cause any dispositions of equity securities of Crosstex (including derivative securities with respect thereto) or acquisitions of equity securities of New Public Rangers (including derivative securities with respect thereto) 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 Crosstex or who will become subject to such reporting requirements with respect to New Public Rangers to be exempt under Rule 16b-3 under the Exchange Act.

6.11 Takeover Laws. If any Takeover Laws or any anti-takeover provision or restriction on ownership in the Organizational Documents of Crosstex is or may become applicable to the Mergers or the other transactions contemplated by this Agreement, Crosstex and the Crosstex Board shall grant such approvals and take all such actions as are necessary or advisable so that such transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise act to eliminate or minimize the effects of such statute, regulation or provision in Crosstex’ Organizational Documents on such transactions.

6.12 Transaction Litigation. Subject to applicable Law, in the event that any Proceeding related to this Agreement, the Mergers or the other transactions contemplated by this Agreement (“Transaction Litigation”) is brought, or, to the Knowledge of Devon or Crosstex, threatened in writing, against a party and/or the members of the party’s Board of Directors prior to the Devon Effective Time, such party against which the Proceeding has been brought or which has Knowledge of such threat shall promptly notify the other party of such Transaction Litigation and shall keep the other party reasonably informed with respect to the status thereof. Each of Devon and Crosstex shall give the other party the opportunity to participate in the defense or settlement of any Transaction Litigation, but no party shall settle, compromise, come to an arrangement regarding or agree to settle, compromise or come to an arrangement regarding any Transaction Litigation, without the other party’s prior written consent (not to be unreasonably withheld, conditioned or delayed); provided, however, that a party may settle any Transaction Litigation without the prior written consent of the other party if such settlement provides (a) for a complete release of the claims, if any, related to or against such other party and (b) that the sole remedy shall be monetary damages, the cost of which is borne entirely by the settling party.

6.13 Exchange Listing. Each of Devon and Crosstex shall use their reasonable best efforts to cause the New Public Rangers Common Units issuable to stockholders of Crosstex in the Crosstex Merger, the New Public Rangers Common Units to be issued upon conversion of the New Public Rangers Class B Units in accordance with the New Public Rangers Limited Liability Company Agreement and such other New Public Rangers Common Units reserved for issuance upon exercise or settlement of options and other equity awards of Crosstex to be approved for listing on a national securities exchange agreed to in writing by Devon and Crosstex (the “Agreed Securities Exchange”), subject to official notice of issuance, prior to the Devon Effective Time.
