The Partnership and/or such Subsidiaries shall be responsible for all Transferred Liabilities, regardless of when or where such Transferred Liabilities arose or arise, or whether the facts on which they are based occurred prior to or subsequent to the Distribution Date, regardless of where or against whom such Transferred Liabilities are asserted or determined, or whether asserted or determined prior to the date hereof, and regardless of whether arising from or alleged to arise from negligence, recklessness, violation of Law, fraud or misrepresentation by any member of the Atlas Energy Group or the Partnership Group, or any of their respective directors, officers, employees, agents, Subsidiaries or Affiliates.

In the event that any Transferred Entity shall hold any Excluded Asset, the Partnership agrees that it shall, or shall cause its applicable Subsidiaries to, assign, transfer, convey and deliver to Atlas Energy or its designated Subsidiary all of such Transferred Entity’s right, title and interest in and to such Excluded Asset, and Atlas Energy agrees to assume and be responsible for any Excluded Liability related to such Excluded Asset.

Section 2.2 Transfer Procedures.

(a) In furtherance of the assignment, transfer, conveyance and delivery of the Transferred Assets and the assumption of the Transferred Liabilities in accordance with Section 2.1, on the date that such Transferred Assets are assigned, transferred, conveyed or delivered or such Transferred Liabilities are assumed, (i) Atlas Energy shall execute and deliver, and shall cause its Subsidiaries to execute and deliver, such bills of sale, quitclaim deeds, stock powers, certificates of title, assignments of contracts and other instruments of transfer, conveyance and assignment as and to the extent necessary to evidence the transfer, conveyance and assignment of all of the right, title and interest of Atlas Energy and its Subsidiaries (other than the Partnership and its Subsidiaries) in and to the Transferred Assets to the Partnership and its Subsidiaries, and (ii) the Partnership shall execute and deliver, and shall cause its Subsidiaries to execute and deliver, such assumptions of contracts and other instruments of assumption as and to the extent necessary to evidence the valid and effective assumption of the Transferred Liabilities by the Partnership and its Subsidiaries.

(b) In the event that at any time or from time to time (whether prior to or after the Distribution Date), any party hereto (or any member of such party’s respective Group), shall receive or otherwise possess any Asset that is allocated to any other Person pursuant to this Agreement, such party shall promptly transfer, or cause to be transferred, such Asset to the Person so entitled thereto. Prior to any such transfer, the Person receiving or possessing such Asset shall hold such Asset in trust for any such other Person.

(c) The parties hereby waive compliance with the requirements and provisions of any “bulk-sale” or “bulk-transfer” Laws of any jurisdiction that may otherwise be applicable with respect to the transfer or sale of any or all of the Assets.

Section 2.3 Approvals and Notifications.

(a) To the extent that the transfer or assignment of any Transferred Asset or Excluded Asset, the assumption of any Transferred Liability or Excluded Liability, the Separation or the Distribution requires any Approvals or Notifications, the parties will use their commercially reasonable efforts to obtain or make such Approvals or Notifications as soon as reasonably practicable; provided, however, that, except to the extent expressly provided in this Agreement, none of Atlas Energy, Atlas Energy GP, the Partnership or the General Partner shall be obligated to contribute capital or pay any consideration in any form (including providing any letter of credit, guaranty or other financial accommodation) to any Person in order to obtain or make such Approvals or Notifications.

(b) If and to the extent that the valid, complete and perfected transfer or assignment of any Transferred Assets or Excluded Asset or assumption of any Transferred Liabilities or Excluded Liability as contemplated by this Agreement would be a violation of applicable Law or require any Approvals or Notifications that has not been obtained or made by the Distribution Date then, unless the parties hereto mutually shall otherwise determine, such transfer, assignment or assumption, as the case may be, shall be automatically deemed deferred and any such purported transfer, assignment or assumption shall be null and void until such time as all legal impediments are removed or such Approvals or Notifications have been obtained or made. Notwithstanding the foregoing, any such Transferred Assets, Excluded Asset, Transferred Liabilities or Excluded Liability shall continue to constitute Transferred Assets, Excluded Asset, Transferred Liabilities or Excluded Liability, respectively, for all other purposes of this Agreement.

(c) If any transfer or assignment of any Transferred Asset or Excluded Asset or any assumption of any Transferred Liabilities or Excluded Liability intended to be transferred, assigned or assumed hereunder, as the case may be, is not consummated on or prior to the Distribution Date, whether as a result of the provisions of Section 2.3(b) or for any other reason, then, insofar as reasonably possible, the Person retaining such Asset or Liability intended to be so transferred or assumed shall thereafter hold such Asset or Liability, as the case may be, for the use and benefit of the Person entitled to receive such Asset or Liability (at the expense of the Person entitled to receive such Asset or Liability). In addition, the Person retaining such Asset or Liability intended to be so transferred or assumed shall, insofar as reasonably possible and to the extent permitted by applicable Law, treat such Asset or Liability in the ordinary course of business in accordance with past practice and take such other actions as may be reasonably requested by the Person entitled to receive such Asset or Liability in order to place such Person entitled to receive such Asset or Liability in a substantially similar position as if such Asset or Liability had been transferred, assigned or assumed as contemplated hereby and so that all the benefits and burdens relating to such Asset or Liability, as the case may be, including use, risk of loss, potential for gain, and dominion, control and command over such Asset or Liability, as the case may be, is to inure from and after the Distribution Date to the Person entitled to receive such Asset or Liability.

(d) If and when the Approvals or Notifications, the absence of which caused the deferral of transfer or assignment of any Asset or the deferral of assumption of any Liability pursuant to Section 2.3(b), are obtained or made, and, if and when any other legal impediments for the transfer or assignment of any Asset or the assumption of any Liability have been removed, the transfer or assignment of the applicable Asset or the assumption of the applicable Liability, as the case may be, shall be effected in accordance with the terms of this Agreement.

Section 2.4 Novation of Transferred Liabilities.

(a) Each of Atlas Energy and the Partnership, at the request of the other, shall use its commercially reasonable efforts to obtain, or to cause to be obtained, as soon as reasonably practicable, any consent, substitution, approval or amendment required to novate or assign all obligations under agreements, leases, licenses and other obligations or Liabilities of any nature whatsoever that constitute Transferred Liabilities, or to obtain in writing the unconditional release of all parties to such arrangements other than any member of the Partnership Group, so

that, in any such case, the members of the Partnership Group will be solely responsible for such Liabilities; provided, however, that, neither Atlas Energy nor the Partnership shall be obligated to contribute any capital or pay any consideration in any form (including providing any letter of credit, guaranty or other financial accommodation) to any third Person from whom any such consent, substitution, approval, amendment or release is requested.

(b) If Atlas Energy or the Partnership is unable to obtain, or to cause to be obtained, any such required consent, substitution, approval, amendment or release and the applicable member of the Atlas Energy Group continues to be bound by such agreement, lease, license or other obligation or Liability (each, an “Unreleased Partnership Liability”), the Partnership shall, to the extent not prohibited by Law, as indemnitor, guarantor, agent or subcontractor for such member of the Atlas Energy Group, as the case may be, (i) pay, perform and discharge fully all the obligations or other Liabilities of such member of the Atlas Energy Group that constitute Unreleased Partnership Liabilities from and after the Distribution Date and (ii) use its commercially reasonable efforts to effect such payment, performance, or discharge prior to any demand for such payment, performance, or discharge is permitted to be made by the obligee thereunder on any member of the Atlas Energy Group. If and when any such consent, substitution, approval, amendment or release shall be obtained or the Unreleased Partnership Liabilities shall otherwise become assignable or able to be novated, Atlas Energy shall promptly assign, or cause to be assigned, and the Partnership shall assume, such Unreleased Partnership Liabilities without exchange of further consideration.

None of Atlas Energy, the Partnership, the General Partner, Atlas Energy GP nor the Partnership Transfer Agent will be required to guarantee any minimum sale price for the fractional Partnership Common Units. None of Atlas Energy, the Partnership, the General Partner, Atlas Energy GP nor the Partnership Transfer Agent will be required to pay any interest on the proceeds from the sale of fractional units.

(d) Until such Partnership Common Units are duly transferred in accordance with applicable law, the Partnership will regard the Persons entitled to receive such Partnership Common Units as record holders of Partnership Common Units in accordance with the terms of the Distribution without requiring any action on the part of such Persons. The Partnership agrees that, subject to any transfers of such units, (i) each such holder will be entitled to receive all distributions payable on, and exercise voting rights and all other rights and privileges with respect to, the Partnership Common Units then held by such holder, and (ii) each such holder will be entitled, without any action on the part of such holder, to receive evidence of ownership of the Partnership Common Units then held by such holder.

ARTICLE 5

INDEMNIFICATION

Section 5.1 Indemnification by the Partnership Group. Subject to the provisions hereof, effective at and after the Distribution Date, the Partnership will, and the Partnership will cause the other members of the Partnership Group to, jointly and severally indemnify, defend and hold harmless Atlas Energy, each member of the Atlas Energy Group, each of their respective past and present officers, directors and employees, each of their respective heirs, executors, successors and assigns, and, solely with respect to clause (d) below, each Person, if any, who controls any of the foregoing parties within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively, the “Atlas Energy Indemnified Parties”) from and against any and all Damages incurred or suffered by the Atlas Energy Indemnified Parties arising out of or in connection with the following, whether such Damages arise or accrue prior to, on or following the Distribution Date:

(a) the Transferred Business or any Transferred Liability;

(b) any breach by the Partnership or any member of the Partnership Group of this Agreement; and

(c) any untrue statement or alleged untrue statement of a material fact contained in the Form 10 or any amendment thereof or the Information Statement (as amended or supplemented if the Partnership will have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading other than any such statement or omission in the Form 10 or Information Statement furnished by Atlas Energy solely in respect of the Atlas Energy Group.

Section 5.2 Indemnification by Atlas Energy Group. Subject to the provisions hereof, effective at and after the Distribution, Atlas Energy will indemnify, defend and hold harmless each member of the Partnership Group, each of their respective past and present officers, directors and employees, and each of their respective heirs, executors, successors and assigns (collectively, the “Partnership Indemnified Parties”) from and against any and all Damages incurred or suffered by the Partnership Indemnified Parties arising out of or in connection with the following, whether such Damages arise or accrue prior to, on or following the Distribution Date:

(a) the Excluded Liabilities; and

(b) any breach by Atlas Energy or any member of the Atlas Energy Group of this Agreement.

provided that nothing in this Agreement shall limit the full rights and benefits intended to be provided to Atlas Energy and its Affiliates (including any rights and benefits to indemnification) pursuant to the terms and conditions of the Amended and Restated LPA or the Amended and Restated LLC Agreement.

Section 5.3 Claim Procedure.

(a) Claim Notice. A party that seeks indemnity under this Article 5 (an “Indemnified Party”) will give written notice (a “Claim Notice”) to the party from whom indemnification is sought (an “Indemnifying Party”), whether the Damages sought arise from matters solely between the parties or from Third Party Claims. The Claim Notice must contain (i) a description and, if known, estimated amount (the “Claimed Amount”) of any Damages incurred or reasonably expected to be incurred by the Indemnified Party, (ii) a reasonable explanation of the basis for the Claim Notice to the extent of facts then known by the Indemnified Party, and (iii) a demand for payment of those Damages. No delay or deficiency on the part of the Indemnified Party in so notifying the Indemnifying Party will relieve the Indemnifying Party of any Liability or obligation hereunder except to the extent of any Damages caused by or arising out of such failure.

(b) Response to Notice of Claim. Within 30 days after delivery of a Claim Notice, the Indemnifying Party will deliver to the Indemnified Party a written response in which the Indemnifying Party will either: (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount and, in which case, the Indemnifying Party will pay the Claimed Amount in accordance with a payment and distribution method reasonably acceptable to the Indemnified Party; or (ii) dispute that the Indemnified Party is entitled to receive all or any portion of the Claimed Amount.

(c) Contested Claims. In the event that the Indemnifying Party disputes the Claimed Amount, as soon as practicable, the parties will begin the process to resolve the matter. Upon ultimate resolution thereof, the parties will take such actions as are reasonably necessary to comply with such terms of resolution.

(d) Third Party Claims.

(i) In the event that the Indemnified Party receives written notice or otherwise learns of the assertion by a Person who is not a member of either Group of any claim or the commencement of any Action (collectively, a “Third-Party Claim”) with respect to which the Indemnifying Party may be obligated to provide indemnification under this Article 5, the Indemnified Party will give written notice to the Indemnifying Party of the Third-Party Claim. Such notification will be given as soon as practicable after receipt by the Indemnified Party of notice of such Third-Party Claim, will be accompanied by reasonable supporting documentation submitted by such third Person (to the extent then in the possession of the Indemnified Party) and will describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such Third-Party Claim and the amount of the claimed Damages; provided, however, that no delay or deficiency on the part of the Indemnified Party in so notifying the Indemnifying Party will relieve the Indemnifying Party of any Liability or obligation hereunder except to the extent of any Damages caused by or arising out of such failure. Within 30 calendar days after delivery of such written notice, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third-Party Claim with counsel reasonably satisfactory to the Indemnified Party. During any period in which the Indemnifying Party has not so assumed control of such defense, the Indemnified Party will control such defense.

(ii) The party not controlling such defense (the “Non-controlling Party”) may participate therein at its own expense; provided, however, that if the Indemnifying Party assumes control of such defense and the Indemnified Party concludes, upon the written opinion of counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such Third-Party Claim, the reasonable fees and expenses of counsel to the Indemnified Party will be considered “Damages” for purposes of this Agreement. The party controlling such defense (the “Controlling Party”) will keep the Non-controlling Party reasonably advised of the status of such Third-Party Claim and the defense thereof and will consider in good faith recommendations made by the Non-controlling Party with respect thereto. The Non-controlling Party will furnish the Controlling Party with such information as it may

have with respect to such Third-Party Claim (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and will otherwise cooperate with and assist the Controlling Party in the defense of such Third-Party Claim.

(iii) The Indemnifying Party will not agree to any settlement of, or the entry of any judgment arising from, any such Third-Party Claim without the prior written consent of the Indemnified Party, which consent will not be unreasonably withheld or delayed; provided, however, that the consent of the Indemnified Party will not be required if (A) the Indemnifying Party agrees in writing to pay any amounts payable pursuant to such settlement or judgment, and (B) such settlement or judgment includes a full, complete and unconditional release of the Indemnified Party from further Liability. The Indemnified Party will not agree to any settlement of, or the entry of any judgment arising from, any such Third-Party Claim without the prior written consent of the Indemnifying Party, which consent will not be unreasonably withheld or delayed.

Section 5.4 Survival; Limitations.

(a) All covenants and agreements of the parties contained in this Agreement will survive each of the Separation and the Distribution. The rights and obligations of Atlas Energy, the Partnership and each of their respective Indemnified Parties under this Agreement will survive the sale, assignment or other transfer by (i) in the case of the Partnership, any Transferred Assets or Transferred Liabilities or (ii) in the case of Atlas Energy, any Excluded Assets or Excluded Liabilities.

(b) The amount of any Damages for which indemnification is provided under this Agreement will be net of any amounts actually recovered by the Indemnified Party from any third Person (including, without limitation, amounts actually recovered under insurance policies) with respect to such Damages. Any Indemnifying Party hereunder will be subrogated to the rights of the Indemnified Party upon payment in full of the amount of the relevant indemnifiable Damages. An insurer who would otherwise be obligated to pay any claim will not be relieved of the responsibility with respect thereto or, solely by virtue of the indemnification provision hereof, have any subrogation rights with respect thereto. If any Indemnified Party recovers an amount from a third Person in respect of Damages for which indemnification is provided in this Agreement after the full amount of such indemnifiable Damages has been paid by an Indemnifying Party or after an Indemnifying Party has made a partial payment of such indemnifiable Damages and the amount received from the third Person exceeds the remaining unpaid balance of such indemnifiable Damages, then the Indemnified Party will promptly remit to the Indemnifying Party the excess (if any) of (X) the sum of the amount theretofore paid by such Indemnifying Party in respect of such indemnifiable Damages plus the amount received from the third Person in respect thereof, less (Y) the full amount of such indemnifiable Damages.

(c) Any indemnification payment made under this Agreement will be characterized for tax purposes as a contribution or distribution or payment of a Transferred Liability or an Excluded Liability, as applicable.

Section 6.9 Amendment. The parties may amend this Agreement only by a written agreement signed by each party to be bound by the amendment and that identifies itself as an amendment to this Agreement.

Section 6.10 Waiver. The parties may waive a provision of this Agreement only by a writing signed by the party intended to be bound by the waiver. A party is not prevented from

enforcing any right, remedy or condition in the party’s favor because of any failure or delay in exercising any right or remedy or in requiring satisfaction of any condition, except to the extent that the party specifically waives the same in writing. A written waiver given for one matter or occasion is effective only in that instance and only for the purpose stated. A waiver once given is not to be construed as a waiver for any other matter or occasion. Any enumeration of a party’s rights and remedies in this Agreement is not intended to be exclusive, and a party’s rights and remedies are intended to be cumulative to the extent permitted by law and include any rights and remedies authorized in law or in equity.

Section 6.11 Construction of Agreement.

(a) Where this Agreement states that a party “will” or “shall” perform in some manner or otherwise act or omit to act, it means that the party is legally obligated to do so in accordance with this Agreement.

(b) The captions, titles and headings, and table of contents, included in this Agreement are for convenience only, and do not affect this Agreement’s construction or interpretation. When a reference is made in this Agreement to an Article or a Section, exhibit or schedule, such reference will be to an Article or Section of, or an exhibit or schedule to, this Agreement unless otherwise indicated.

(e) This Agreement is not to be construed for or against any party based on which party drafted any of the provisions of this Agreement. The language used in this Agreement is the language chosen by the parties to express their mutual intent, and no provision of this Agreement will be interpreted for or against any party because that party or its attorney drafted the provision.

Indemnified Parties and the Partnership Indemnified Parties under this Agreement do not, and are not intended to, confer any rights or remedies in favor of any Person (including any employee or unitholder of Atlas Energy or the Partnership) other than the parties signing this Agreement and their respective Group members.

Section 6.12 Termination.

(a) This Agreement may be terminated and the Distribution abandoned at any time prior to the Distribution Date by and in the sole discretion of the board of directors of Atlas Energy GP without the approval of any Person, including the Partnership or the General Partner, in which case no party will have any liability of any kind to any other party by reason of this Agreement. After the Distribution Date, this Agreement may not be terminated except by an agreement in writing signed by each of the parties to this Agreement.

(b) The obligations of the parties under Article 3 (including the obligation to pursue or effect the Distribution) may be terminated by Atlas Energy if, at any time, Atlas Energy GP determines, in its sole discretion, that the Distribution would not be in the best interests of Atlas Energy or its unitholders.
