APL shall file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes and, if required by applicable Law, the Parties hereto shall, and shall cause their respective Affiliates to, join in the execution of any such Tax Returns and other documentation; provided, however, that to the extent that Atlas or any of its Affiliates is required to join in the execution of any such Tax Return or documentation, (i) APL shall prepare and deliver to Atlas or such Affiliate a copy of such Tax Return at least ten (10) days before the due date thereof and (ii) APL shall not file such Tax Return without the consent of Atlas, which consent shall not be unreasonably withheld, conditioned or delayed. APL will indemnify and hold harmless Atlas from and against, and will reimburse Atlas upon demand and proof of payment for, any amounts paid by Atlas or the Atlas Group for which APL is responsible under this Section 5.8. Atlas will indemnify and hold harmless APL from and against, and will reimburse APL upon demand and proof of payment for, any amounts paid by APL or the APL Group for which Atlas is responsible under this Section 5.8.

(b) Cooperation. Atlas and APL shall provide each other with such assistance as reasonably may be requested by either of them in connection with (i) the preparation of any Tax Return, or (ii) any audit or other examination by any taxing authority, or any judicial or administrative proceedings relating to liability for Taxes. The Party requesting assistance hereunder shall reimburse the other Party for reasonable out-of-pocket expenses incurred in providing such assistance.

(c) Survival of Obligations. Notwithstanding any other provisions of the Agreement, the obligations of the Parties set forth in this Section 5.8 shall be unconditional and absolute, shall not be subject to any limitation contained in Article VIII and shall remain in effect until ninety (90) days after the expiration of the applicable statutes of limitations (including extensions thereof).

(d) Exclusive Remedy. Notwithstanding anything to the contrary in this Agreement, the rights and obligations of the Parties with respect to indemnification for Transfer Taxes shall be governed by this Section 5.8 and shall not be governed by Article VIII.

(e) Post-Closing Matters. The Parties acknowledge that for federal and applicable state and local income tax purposes, any adjustment to the income or loss of Laurel Mountain for periods prior to Closing will, and any such adjustment for periods that include the Closing may, result in adjustments to the income or loss of APL. Accordingly, each of Atlas and

ATN agrees and covenants that in the event of any tax audit or controversy concerning income Taxes for any periods that end on or before the Closing, it (i) will exercise all rights under the LMM Agreement with respect to such audit or controversy to the extent related to such periods as reasonably instructed by APL, including immediately forwarding to APL any communications from the Tax Matters Member (as defined in the LMM Agreement) relating in whole or in part to income Taxes for such periods and immediately requesting any information from the Tax Matters Member that APL specifies in writing, (ii) will use commercially reasonable efforts to cause the Tax Matters Member and the applicable taxing authority to deal directly with APL with respect to income Taxes for such periods, and (iii) will not settle or compromise (or purport to settle or compromise) any issue with respect to such periods or that affects income Taxes for such periods without the prior written consent of APL; provided, however, that APL shall not settle or compromise (or purport to settle or compromise) any issue with respect to such periods that results in a Tax Detriment to Atlas without the consent of Atlas. To the extent any tax audit or controversy concerns both income Taxes for periods that end on or before the Closing and income Taxes for periods that begin after the Closing, the Parties will cooperate to permit the views and interests of both APL and Atlas to be reflected and for both Parties to be kept informed. Each Party shall bear any expenses incurred by it in undertaking any actions pursuant to this Section 5.8(e). The Parties acknowledge that for the taxable year of Laurel Mountain that includes the Closing, both APL Sub and ATN should be viewed as “partners” for income Tax purposes and thus would be expected to be able to independently exercise rights in any such audit or contest, both as to rights against the Tax Matters Member and as to rights before the relevant tax authority.

5.9

Specified Agreements.

Atlas and ATN hereby agree to furnish to APL and APL Sub, concurrently with the execution and delivery thereof, copies of any amendments, supplements and restatements of, and any waivers of any of the terms or conditions of, any Specified Agreement.

5.10

Pipeline Surface Rights.

No later than forty-five (45) days following execution and delivery of this Agreement, Atlas shall, and shall cause its Subsidiaries to, (a) execute and deliver to Laurel Mountain Midstream Operating LLC (“LMO”) a blanket assignment with special warranty containing such terms as are reasonably necessary to convey to LMO in the manner contemplated by the Formation Agreement, all easements, rights of way and surface and related rights (collectively, the “Pipeline Surface Rights”) shown on Schedule 4.6(d) to the Formation Agreement, in each case to the extent any such Pipeline Surface Rights relate to the pipeline system and related assets conveyed or purported to be conveyed pursuant to the Formation Agreement and where such Pipeline Surface Rights were not conveyed as a consequence of a failure of Atlas or any Affiliate of Atlas to previously convey, in whole or in part, such Pipeline Surface Rights to APL or any Affiliate of APL, it being expressly understood and agreed that the foregoing blanket assignment shall contain no covenant of seisin or other representation or warranty of Atlas’ ownership of any easements, rights of way and surface and related rights except the aforementioned special warranty, and (b) reasonably cooperate with APL to include in such blanket assignment all other Pipeline Surface Rights arising under oil and gas leases that are not shown on Schedule 4.6(d) to the Formation Agreement to the extent not prohibited under the

terms and conditions of such oil and gas leases and further to the extent such Pipeline Surface Rights relate to the pipeline system and related assets conveyed or purported to be conveyed pursuant to the Formation Agreement but such Pipeline Surface Rights were not so conveyed. Thereafter, Atlas will, and will cause its Subsidiaries to, execute and deliver one or more memoranda of assignment memorializing the blanket assignment of the Pipeline Surface Rights described above that are suitable for recording.

ARTICLE VIII

SURVIVAL AND INDEMNIFICATION; REIMBURSEMENT OF EXPENSES

8.1

Survival Periods.

All representations and warranties, and all covenants that contemplate or may involve actions to be taken or obligations in effect prior to the Closing, in each case contained in this Agreement or in any Schedule to this Agreement, and the right to commence any claim with respect thereto under Section 8.2(a) or 8.3(a), shall terminate and cease to be of further force and effect as of the date that is 12 months after the Closing Date; provided that the representations and warranties set forth in Sections 3.2(a), (b) and (d), 3.8 and 4.4 shall survive indefinitely. Those covenants that contemplate or may involve actions to be taken or obligations in effect at or after the Closing shall survive in accordance with their terms. Notwithstanding the foregoing, any covenant, agreement, representation, warranty or other matter in respect of which indemnity may be sought under this Agreement shall survive the time at which it would otherwise terminate pursuant to this Section 8.1, if notice of the inaccuracy or breach thereof or other matter giving rise to such right of indemnity shall have been given to the Party against whom such indemnity may be sought prior to such time.

8.2

Indemnification by APL.

Subject to Section 8.5, from and after the Closing Date, APL and APL Sub, jointly and severally, shall indemnify and hold harmless Atlas and each other member of the Atlas Group, each of their respective directors, officers, employees and agents, and each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “Atlas Indemnified Parties”) from and against any and all Losses to the extent resulting from or arising out of:

(a) any breach or inaccuracy of any representation or warranty of APL or APL Sub contained in this Agreement;

(b) any breach of any covenant or agreement contained in this Agreement to be performed by APL or APL Sub; or

8.3

Indemnification by Atlas.

Subject to Section 8.5, from and after the Closing Date, Atlas and ATN, jointly and severally, shall indemnify and hold harmless APL and each other member of the APL Group, each of their respective directors, officers, employees and agents, and each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “APL Indemnified Parties” and together with Atlas Indemnified Parties the “Indemnified Parties”) from and against any and all Losses resulting from or arising out of:

(a) any breach or inaccuracy of any representation or warranty of Atlas contained in this Agreement; or

(b) any breach of any covenant or agreement contained in this Agreement to be performed by Atlas or ATN.

8.4

Third-Party Claims.

If a claim by a third party is made against an Indemnified Party, and if such Indemnified Party intends to seek indemnity with respect thereto under this Article VIII, such Indemnified Party, shall promptly notify Atlas, if an APL Indemnified Party, or APL, if an Atlas Indemnified Party (Atlas or APL, as the case may be, the “Indemnifying Party”), of such claims. The failure to provide such notice shall not result in a waiver of any right to indemnification hereunder except to the extent that the Indemnifying Party is actually materially prejudiced by such failure. The Indemnifying Party shall have 30 days after receipt of such notice to elect to undertake, conduct and control, through counsel of its own choosing and at its own expense, the settlement or defense thereof (provided that the Indemnifying Party acknowledges in writing its obligation to indemnify the Indemnified Party in respect of such claim), and the Indemnified Party shall cooperate with it in connection therewith. Notwithstanding the foregoing, an Indemnified Party shall have the right to employ separate counsel at the Indemnifying Party’s expense if the named parties to any such proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and the reasonable expenses of such counsel shall be at the expense of the Indemnifying Party). Notwithstanding the foregoing, in no event shall an Indemnifying Party be required to pay the expenses of more than one (1) separate counsel. The Indemnified Party shall not pay or settle any claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed). Notwithstanding the foregoing, the Indemnified Party shall have the right to pay or settle any such claim; provided that, in such event, it shall waive any right to indemnity therefor by the Indemnifying Party. The Indemnifying Party shall not, except with the consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed), enter into any settlement unless (i) such settlement includes as an unconditional term thereof the giving by the Person or Persons asserting such claim to all Indemnified Parties an unconditional release from all liability with respect to such claim and (ii) the only relief imposed against such Indemnified Party is the payment of monetary damages which are paid by the Indemnifying Party.

8.5

Limitations.

(a) No indemnity shall be payable to the Atlas Indemnified Parties under Section 8.2(a) with respect to any claim resulting from any breach or inaccuracy of any representation or warranty, unless and until the aggregate of all Losses due from APL exceeds $8,040,000, in which event all Losses so due in excess of such amount shall be paid in full by APL; provided that the aggregate amount payable by APL under Section 8.2(a), with respect to

claims resulting from any breach or inaccuracy of a representation or warranty, shall not exceed $40,200,000. Notwithstanding anything to the contrary contained in this Agreement, APL shall not be required to indemnify any Atlas Indemnified Party with respect to any Loss (or series of related Losses) incurred by or asserted by reason of any breach of any representation, warranty or covenant contained in this Agreement if the Loss (or series of related Losses) from such breach is less than $50,000, nor shall any such Losses be included in the calculation of the amounts specified in this Section 8.5(a). The limitations set forth in this Section 8.5(a) shall not apply with respect to the representations and warranties set forth in Sections 3.2 and 3.8.

(b) No indemnity shall be payable to the APL Indemnified Parties under Section 8.3(a) with respect to any claim resulting from any breach or inaccuracy of any representation or warranty, unless and until the aggregate of all Losses due from Atlas exceeds $8,040,000, in which event all Losses so due in excess of such amount shall be paid in full by Atlas; provided that the aggregate amount payable by Atlas under Section 8.3(a), with respect to claims resulting from any breach or inaccuracy of a representation or warranty, shall not exceed $40,200,000. Notwithstanding anything to the contrary contained in this Agreement, Atlas shall not be required to indemnify any APL Indemnified Party with respect to any Loss (or series of related Losses) incurred by or asserted by reason of any breach of any representation, warranty or covenant contained in this Agreement if the Loss (or series of related Losses) from such breach is less than $50,000, nor shall any such Losses be included in the calculation of the amounts specified in this Section 8.5(b). The limitations set forth in this Section 8.5(b) shall not apply with respect to the representations and warranties set forth in Section 4.4.

8.6

Mitigation; Additional Indemnification Provisions.

Each Indemnified Party shall use commercially reasonable efforts to mitigate any claim or liability that an Indemnified Party asserts under this Article VIII, and such Indemnified Party shall be entitled to recover from the Indemnifying Party any costs or expenses incurred to mitigate such claim or liability. For purposes of this Agreement, Losses shall be net of any Tax Benefit actually realized (either by cash refund or actual reduction of Taxes otherwise payable) and net of any Tax Detriment actually realized (either by a reduction in cash refund or increase in Taxes otherwise payable) by the Indemnified Party or its Affiliates during or prior to the Tax period in which the indemnification payment is made arising in connection with the accrual, incurrence or payment of any such Losses. The Indemnified Party shall use commercially reasonable efforts (exercising its reasonable discretion in relation to the availability of such Tax Benefit and ability not to suffer such Tax Detriment) to claim such Tax Benefit and not suffer such Tax Detriment. Any Indemnified Party having a claim under these indemnification provisions shall make a good-faith effort to recover all losses, costs, damages and expenses from insurers of such Indemnified Party under applicable insurance policies so as to reduce the amount of any Losses hereunder; provided that actual recovery of any insurance shall not be a condition to the Indemnifying Party’s obligation to make indemnification payments to the Indemnified Party in accordance with the terms of this Agreement. If the Indemnifying Party receives any amounts under applicable insurance policies, or from any other Person alleged to be responsible for Loss, after an indemnification payment by the Indemnifying Party has been made for such Loss, then the Indemnified Party shall promptly reimburse the Indemnifying Party for such indemnification payment up to the amount so received or realized (on an after-tax basis) by the Indemnified Party. No Indemnified Party will, in any event, be entitled to any incidental,

indirect, consequential, special, exemplary or punitive damages, including damages for lost profits or opportunity costs or damages based upon a multiple of earnings or other financial measure, except for those of the foregoing paid to third parties in an otherwise indemnifiable matter.

8.7

Exclusive Remedies.

(a) Except with respect to the matters covered by Sections 5.8 and 10.12, the Parties acknowledge and agree that, following the Closing, the indemnification provisions of Article VIII shall be the sole and exclusive monetary remedies of the Parties (other than in the case of fraud or willful misconduct), respectively, for any Losses (including any Losses from claims for breach of contract, warranty or otherwise and whether predicated on common law, statute, strict liability, or otherwise) that each Party may at any time suffer or incur, or become subject to, as a result of, or in connection with, any breach of any representation or warranty in this Agreement by another Party or any failure by such other Party to perform or comply with any covenant or agreement that, by its terms, was to have been performed, or complied with, by such other Party prior to the Closing or, in the case of Article IX, after the Closing, or any other matter in respect of which such Party may be entitled to indemnification pursuant to Section 8.2. Without limiting the generality of the foregoing, the Parties to this Agreement hereby irrevocably waive any right of rescission they may otherwise have or to which they may become entitled.

(b) Notwithstanding anything herein to the contrary, in the event APL or APL Sub is in breach of Section 3.2(a), or fails to comply with Sections 5.3(b)(v) because its compliance therewith would result in a default under the APL Credit Agreement or any APL Indenture, the ability to terminate this Agreement pursuant to Section 7.1(c)(i) shall be the sole and exclusive remedy of Atlas and ATN, which remedy must be exercised within (30) days written notice to Atlas and ATN of APL’s or APL Sub’s breach or failure to comply with the applicable terms hereof.

8.8

Reimbursement of Expenses.

Atlas and ATN agree to pay, upon the termination of this Agreement prior to the Closing (other than a termination of this Agreement by Atlas pursuant to Section 7.1(c)(i)), to APL or its designee, by wire transfer of immediately available funds to an account or accounts designated in writing by APL, an amount equal to the sum of all reasonable out-of-pocket fees and expenses (including (i) fees and expenses of (A) the directors of APL GP, (B) the APL Special Committee, and (C) legal counsel and financial advisors to APL and the APL Special Committee, and (ii) fees paid by any APL Group member to any third party in connection with obtaining the consent from any such third party, including the consent contemplated under Section 6.1(b) in respect of the APL Credit Agreement) incurred by any APL Group member in connection with the Sale, whether incurred before, on or after the date of this Agreement; provided that in no event shall the aggregate payment obligation under this sentence exceed $3,000,000. The obligations of Atlas and ATN under this Section 8.8 shall be joint and several, and shall survive termination of this Agreement. Except as set forth in this Section 8.8, whether or not the Sale is consummated, all costs and expenses incurred in connection with the Sale, this Agreement and the transactions contemplated hereby shall be paid by the Party incurring or required to incur such expenses.

ARTICLE IX

POST-CLOSING OBLIGATIONS

9.1

Subsequent Transfers.

(a) If (i) the Closing occurs but the Merger is not consummated promptly thereafter, and (ii) there is a Subsequent Transfer on or before the one-year anniversary of the Closing where the Sale Value for such Subsequent Transfer exceeds the Subsequent Transfer Value for such Subsequent Transfer, then Atlas shall pay to APL in accordance with the following provisions of this Section 9.1 an amount (the “Subsequent Transfer Amount”) equal to 50% of the amount by which the Sale Value exceeds the Subsequent Transfer Value.

(b) Promptly after the completion of any Subsequent Transfer pursuant to which Atlas would be required to pay a Subsequent Transfer Amount, Atlas and ATN shall provide written notice (a “Subsequent Transfer Notice”) to APL thereof, and shall furnish together with such notice a complete and correct copy of the binding agreement or commitment for such Subsequent Transfer, and Atlas and ATN shall promptly provide such other information with respect thereto as may reasonably be requested by APL. The Subsequent Transfer Amount shall be payable to APL in same form of consideration as Atlas or ATN shall have received in the Subsequent Transfer; provided that, at the option of Atlas and ATN, Atlas and ATN, as the case may be, may substitute cash for all or a portion of any non-cash consideration, with such non-cash consideration valued in accordance with Section 9.1(c).

(c) In the event that Atlas or ATN determines to substitute cash for any non-cash consideration pursuant to Section 9.1(b), any non-cash consideration shall be deemed have a fair market value of: (i) in the case of any publicly traded securities, the most recent closing price preceding the closing of the Subsequent Transfer of such securities on the national securities exchange on which such securities are listed, and (ii) in the case of any other non-cash consideration, as determined by an investment banking firm of recognized national standing not associated with APL, Atlas or any of their respective Affiliates (the “Appraiser”), which shall be jointly selected by APL and Atlas (it being understood and agreed that if APL and Atlas are unable to agree upon an Appraiser to conduct such an appraisal within ten (10) days of the date of the Subsequent Transfer Notice, either of them may request that the American Arbitration Association, or any organization successor thereto, select an appropriate Appraiser). If any property (the “Other Assets”) other than the Acquired LMM Interests in, or assets of, any Atlas Group member, are proposed to be transferred in connection with any Subsequent Transfer, then, for purposes of determining the Subsequent Transfer Amount (if any) payable to APL pursuant to Section 9.1(a), the consideration in the Subsequent Transfer shall be deemed not to include any portion thereof allocable to such Other Assets. Atlas or ATN shall provide an allocation of such consideration within ten (10) Business Days following the closing date of the Subsequent Transfer by the Appraiser. Each Party shall have a reasonable opportunity to provide evidence to the Appraiser with respect to such allocation (which evidence shall be provided simultaneously to the other Party), and the Appraiser’s determination shall be set forth in writing in reasonable detail. All fees, costs and other expenses of the Appraiser pursuant to this Section 9.1(c) shall be borne equally by any applicable Atlas Group member, on the one hand, and APL, on the other hand.

9.2

Agreement for Exchange of Information; Archives.

(a) After the Closing and until the fifth anniversary of the Closing Date, each of Atlas, ATN and APL agrees to provide, or cause to be provided, to the other, as soon as reasonably practicable after written request therefor, any Information in the possession or under the control of such Party which the requesting Party reasonably needs (i) to comply with reporting, disclosure, filing or other requirements imposed on the requesting Party (including under applicable securities Laws) by a Governmental Entity having jurisdiction over the requesting Party, (ii) in order to satisfy audit, accounting or other similar requirements, (iii) to comply with its obligations under this Agreement, the LMM Agreement, the Formation Agreement or any other agreement related to Laurel Mountain or its business or assets, and (iv) in connection with the matters described in Section 3.10 of the APL Disclosure Letter or for other matters for which indemnity is sought by LMM or its members pursuant to the Formation Agreement; provided, however, that, in the case of clauses (i), (ii) and (iii), in the event that any Party determines that any such provision of Information could be commercially detrimental, violate any Law or agreement, or waive any attorney-client privilege, the Parties shall take all reasonable measures to permit the compliance with such obligations in a manner that avoids any such harm or consequence.

(b) After the Closing and until the fifth anniversary of the Closing Date, APL and its authorized accountants, counsel and other designated representatives shall have access during regular business hours (as in effect from time to time) to the documents that relate to the Acquired LMM Interest that are located in archives retained or maintained by any member of the Atlas Group.

9.3

Record Retention.

(a) To facilitate the possible exchange of Information pursuant to Section 9.2 and other provisions of this Agreement after the Closing, Atlas and APL each agree to use their commercially reasonable efforts to retain, and to cause their respective Subsidiaries to retain, all Information in their respective possession or control (including, with respect to Atlas, any books, records and files transferred by APL Sub to Atlas pursuant to Section 5.7) in accordance with the policies or ordinary course practices of Atlas or APL, as applicable, in effect on the Closing Date or such other policies or practices as may be reasonably adopted by the applicable Party after the Closing.

(b) Except in accordance with its policies and ordinary course practices, no Party will destroy, or permit any of its Subsidiaries to destroy, any Information that would, in accordance with such policies or ordinary course practices, be archived or otherwise filed in a centralized filing system by such Party or its applicable Subsidiaries; provided, however, that no Party will destroy, or permit any of its Subsidiaries to destroy, any Information required to be retained by applicable Law.

(c) In the event of any Party’s inadvertent failure to comply with its applicable document retention policies as required under this Section 9.3, such Party shall be liable to the other Party solely for the amount of any monetary fines or penalties imposed or levied against such other Party by a Governmental Entity (which fines or penalties shall not

include any Liabilities asserted in connection with the claims underlying the applicable Action, other than fines or penalties resulting from any claim of spoliation) as a result of such other Party’s inability to produce Information caused by such inadvertent failure and shall not otherwise be liable hereunder to such other Party for such inadvertent failure.

9.4

Production of Witnesses; Records; Cooperation.

(a) After the Closing, except in the case of an adversarial Action by one Party against another Party, each Party hereto shall use its commercially reasonable efforts to make available to each other Party, upon written request, the former, current and future directors, officers, employees, other personnel and agents of the members of the Atlas Group or the APL Group, as applicable, as witnesses and any books, records or other documents within its control or which it otherwise has the ability to make available, to the extent that any such Person (giving consideration to business demands of such directors, officers, employees, other personnel and agents) or books, records or other documents may reasonably be required in connection with any Action in which the requesting Party may from time to time be involved. The requesting Party shall bear all out-of-pocket costs and expenses in connection therewith.

(b) The obligation of the Parties to provide witnesses pursuant to this Section 9.4 is intended to be interpreted in a manner so as to facilitate cooperation and shall include the obligation to provide as witnesses the persons specified therein without regard to whether the witness or the employer of the witness could assert a possible business conflict (subject to the exception set forth in the first sentence of Section 9.4(a)).

10.2

Interpretation.

When a reference is made in this Agreement to Sections, Articles, or Exhibits, such reference shall be to a Section or Article of or Exhibit to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement or in any Exhibit are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Any capitalized terms used in any Exhibit but not otherwise defined therein shall have the meaning set forth in this Agreement. All Exhibits annexed hereto or referred to herein are hereby incorporated in and made a part of this Agreement as if set forth herein. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation,” unless otherwise specified. The words “hereby,” “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The words “date hereof” shall refer to the date of this Agreement. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” The term “or” shall not be deemed to be exclusive. The phrase “transactions contemplated by this Agreement” and similar phrases shall mean the Sale, and shall not include the transactions to be consummated under the Merger Agreement or the AHD Transaction Agreement. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined therein. The words describing the singular number shall include the plural and vice versa and words denoting any gender shall include all genders. References to a Person are also to its successors and permitted assigns. Reference to any agreement (including this Agreement), document or instrument shall mean such agreement, document or instrument as amended, modified or supplemented (including by waiver or consent) and in effect from time to

time in accordance with the terms thereof and, if applicable, the terms hereof. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provisions of this Agreement.

10.3

Amendment.

Any provision of this Agreement may be amended or supplemented if such amendment or supplement is in writing and signed by the Parties hereto. This Agreement may not be amended or supplemented in any manner, whether by course of conduct or otherwise, except by an instrument in writing specifically designated as an amendment hereto, signed on behalf of each of the Parties in interest at the time of the amendment.

10.4

Extension; Waiver.

The Parties may, to the extent permitted by applicable Law, (a) extend the time for the performance of any of the obligations or other acts of the Parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto or (c) waive compliance with any of the agreements or conditions contained herein of the other Party or Parties contained herein. Any agreement on the part of a Party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party. No failure or delay by any Party in exercising any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder. Except as otherwise provided herein, the rights and remedies of the Parties hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder.

10.5

Counterparts.

This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which shall constitute one and the same instrument. This Agreement shall become effective when each Party hereto shall have received counterparts thereof signed and delivered (by confirmed facsimile transmission or electronic mail or otherwise) by the other Parties hereto.

10.6

Entire Agreement; Third-Party Beneficiaries.

(a) This Agreement (including the Exhibits and the Parties’ disclosure schedules hereto) constitutes the entire agreement, and supersedes all prior agreements and understandings, both written and oral, between the Parties with respect to the transactions contemplated hereby.

(b) Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person other than the Parties and their respective successors and permitted assigns any right or remedy hereunder, other than (i) with respect to the provisions of Article VIII, which shall inure to the benefit of the Indemnified Parties, who are hereby intended to be third-party beneficiaries thereof, and the provisions of Section 10.13, which shall inure to

the benefit of AHD and AHD GP, who are hereby intended to be third-party beneficiaries thereof and (ii) prior to the Merger, the provisions of Section 10.12 applicable to Atlas’s and/or ATN’s right to specific performance to require APL and APL Sub to comply with their obligations under this Agreement shall be enforceable by Chevron and its successors and assigns.

10.7

Severability.

Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable Law, but if any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect. Notwithstanding the foregoing, upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

10.8

Assignment.

Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the Parties without the prior written consent of the other Parties, and any attempted assignment of this Agreement or any of such rights, interests or obligations without such consent shall be void and of no effect; provided that, upon written notice to APL and APL Sub, (a) Atlas or ATN may, without the consent of APL, assign any or all of its rights, interests and obligations hereunder to a direct or indirect wholly owned Subsidiary of Atlas, but no such assignment shall relieve Atlas or ATN of any of its obligations hereunder; and (b) ATN may, without the consent of APL, any or all of its rights, interests and obligations hereunder to Atlas. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the Parties and their respective successors and permitted assigns.

10.9

Governing Law.

This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware, without regard to any conflicts of Law rules (whether of the State of Delaware or of any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware.

10.10

Exclusive Jurisdiction for Disputes.

The Parties hereto agree that any Action seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby (whether brought by any Party or any of its Affiliates or against any Party or any of its Affiliates) shall only be brought in the Delaware Chancery Court or, if such court shall not have jurisdiction, any federal court located in the State of Delaware or other Delaware state court, and each of the Parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such Action and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such Action in any such court or that any such Action brought in any such

court has been brought in an inconvenient forum. Process in any such Action may be served on any Party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each Party agrees that service of process on such Party as provided in Section 10.1 shall be deemed effective service of process on such Party.

10.11

WAIVER OF JURY TRIAL.

EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

10.12

Specific Performance.

The Parties hereto agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached. Subject to Section 8.7(b), it is accordingly agreed that the Parties and, to the extent set forth in Section 10.6(b), Chevron, shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to specific performance of the terms and provisions hereof in any court of competent jurisdiction, this being in addition to any other remedy to which they are entitled at Law or in equity, including provisions contained herein relating to reimbursement of expenses or termination fees.

10.13

APL Acknowledgment.

APL hereby waives any rights that APL may have pursuant to Section 2.1 of the Omnibus Agreement dated, as of July 26, 2006, by and among AHD, AHD GP and APL in respect of any of the transactions contemplated by the AHD Transaction Agreement or in respect of the operation of any of the businesses or assets acquired thereby.

10.14

ATN Acknowledgement.

ATN hereby waives any rights that ATN may have pursuant to Section 2 of the ATN Option Agreement, dated as of June 1, 2009, by and among ATN, Atlas Pipeline Operating Partnership, L.P. and APL Sub in respect of any of the transactions contemplated by this Agreement, including the transfer of the Acquired LMM Interest by APL Sub contemplated hereby.

10.15

Alternative Structure.

Notwithstanding anything to the contrary contained in this Agreement, before the Closing, if requested by Atlas, the Parties will cooperate in good faith to revise the structure of the Sale to provide for the immediate contribution of the Acquired LMM Interest to a newly-formed, wholly-owned Subsidiary of APL Sub (“Newco”) and the acquisition of Newco by ATN at the Closing contemplated hereunder; provided, however, that (1) such revision does not alter or change the kind or amount of consideration to be delivered to APL Sub, (2) such revised structure or method does not materially delay consummation of the transactions contemplated by this Agreement in relation to the structure contemplated herein, (3) such revision does not, and is

not reasonably likely to, otherwise cause any of the conditions set forth in Article VI not to be capable of being fulfilled (unless duly waived by the Party entitled to the benefits thereof) and (4) such revision does not diminish or otherwise adversely affect any rights or benefits accruing, or expected to accrue, to, or increase or expand or otherwise adversely affect any costs, liabilities, burdens or obligations (including any tax obligations) of, APL or APL Sub under this Agreement. The Parties agree to cooperate in good faith to appropriately amend this Agreement and any related documents in order to reflect any such revised structure or method.
