(b) Within a reasonable time after the date of this Contribution Agreement, and without any further consideration, Atlas America agrees to cause to be delivered to Atlas Energy true and complete executed copies of (i) all the agreements of limited partnership of the Investment Programs, (ii) all the drilling operating agreements of the Investment Programs and (iii) any other material agreements to which any of the Investment Programs is a party (collectively, the “Investment Program Documents”), in the case of each of clauses (i) through (iii), that were not executed or made available to Atlas Energy as of the date of this Contribution Agreement.

Section 6.2 Other Assurances. From time to time after the date of this Contribution Agreement, and without any further consideration, each of the Parties shall execute, acknowledged and deliver all such additional instruments, notices and other documents, and will do all such other acts and things, all in accordance with applicable law, as may be necessary or appropriate to more fully and effectively carry out the purposes and intent of this Contribution Agreement. Without limiting the generality of the foregoing, the Parties acknowledge that the Parties have used their good faith efforts to identify all the assets being contributed to the Atlas Energy Group as required in connection with the Offering. However, due to the age of some of those assets or the difficulties in locating appropriate data with respect to some of the assets, it is possible that assets intended to be contributed to the Atlas Energy Group were not identified and therefore are not included in the Assets. It is the express intent of the Parties that the Atlas Energy Group will own all assets of the Business as of the Closing Date and as described in the Registration Statement. To the extent any assets were not identified but are necessary to the operation of assets that were identified, then the intent of the Parties is that all such unidentified assets are intended to be conveyed to the appropriate members of the Atlas Energy Group. To the extent such assets are identified at a later date, the Parties shall take the appropriate actions required in order to convey all such assets to the appropriate members of the Atlas Energy Group. Likewise, to the extent that assets are identified at a later date that were not intended by the Parties to be conveyed as reflected in the Registration Statement, the Parties shall take the appropriate actions required in order to convey all such assets to the appropriate party.

(a) any violation or correction of violation of Environmental Laws associated with the ownership or operation of the Atlas Energy Assets, or

(b) any event or condition associated with ownership or operation of the Transferred Assets (including the presence of Hazardous Substances on, under, about or migrating to or from the Atlas Energy Assets or the disposal or release of Hazardous Substances generated by operation of the Atlas Energy Assets at non-Atlas Energy Asset locations) including (i) the cost and expense of any investigation, assessment, evaluation, monitoring, containment, cleanup, repair, restoration, remediation, or other corrective action required or necessary under Environmental Laws, (ii) the cost or expense of the preparation and implementation of any closure, remedial, corrective action, or other plans required or necessary under Environmental Laws, and (iii) the cost and expense for any environmental or Toxic Tort pre-trial, trial, or appellate legal or litigation support work;

but only to the extent that such violation complained of under Section 7.2(a) or such events or conditions included under Section 7.2 (b) occurred or existed before the Closing Date (collectively, “Covered Environmental Losses”).

Section 7.3 Limitations Regarding Environmental Indemnification. The aggregate liability of Atlas America in respect of all Covered Environmental Losses under Section 7.2 shall not exceed $25,000,000 and Atlas America will not have any obligation under Section 7.2 until the Covered Environmental Losses of the Atlas Energy Group exceed $500,000.

Section 7.4 Indemnification by Atlas America. In addition to and not in limitation of the indemnification provided under Sections 7.2, Atlas America shall indemnify, defend and hold harmless each member of the Atlas Energy Group and such member’s directors, officers, members, employees and representatives from and against any losses, damages, liabilities, claims, demands, causes of action, judgments, settlements, fines, penalties, costs and expenses (including court costs and reasonable attorney’s fees and expert’s fees) of any and every kind and character, known or unknown, fixed or contingent, suffered or incurred by the Atlas Energy Group (“Losses”), insofar as such Losses arise out of or are based upon:

(a) a breach of the representations and warranties of Atlas America set forth in Section 5.1 hereof;

(b) the failure of Atlas America to perform its obligations under Section 3.1 after the Closing Date;

(d) all federal, state and local income tax liabilities attributable to the operation of the Transferred Assets prior to the Closing Date, including any such income tax liabilities of Atlas America and its subsidiaries that may result from the consummation of the formation transactions for the Atlas Energy Group and Atlas Management; or

(e) the failure of Atlas America and its subsidiaries to execute, deliver and provide to Atlas Energy the Investment Program Documents.

Section 7.6 Indemnification by Atlas Energy. Atlas Energy and Energy Operating, jointly and severally, shall indemnify, defend and hold harmless Atlas America and such entity’s directors, officers, members, employees and representatives from and against all Losses (including court costs and reasonable attorney’s and expert’s fees) of any and every kind or character, known or unknown, fixed or contingent, suffered or incurred by Atlas America insofar as such Losses arise out of or are based upon:

(a) the Assumed Liabilities, unless such indemnification would not be permitted under the Operating Agreement; or

(b) the failure of Atlas Energy to perform its obligations under Section 3.2 after the Closing Date.

Section 7.7 Indemnification Procedure.

(a) The indemnified party agrees that within a reasonable period of time after it becomes aware of facts giving rise to a claim for indemnification under this Article VII, it will provide notice thereof in writing to the indemnifying party, specifying the nature of and specific basis for such claim.

(b) The indemnifying party shall have the right to control, at its sole cost and expense, all aspects of the defense of (and any counterclaims with respect to) any claims brought against the indemnified party that are covered by the indemnification under this Article VII, including the selection of counsel, determination of whether to appeal any decision of any Authority and the settling of any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent of the indemnified party (which consent shall not be unreasonably withheld), with the concurrence of the Conflicts Committee of Atlas Energy in the case of the Atlas Energy Group, unless it includes a full release of the indemnified party from such matter or issues, as the case may be.

(c) The indemnified party agrees to cooperate fully with the indemnifying party, with respect to (i) its pursuit of insurance coverage or recoveries with respect to the claims covered by the indemnification and (ii) all aspects of the defense of any claims covered by the indemnification, including the prompt furnishing to the indemnifying party of any correspondence or other notice relating thereto that the indemnified party may receive, permitting the name of the indemnified party to be utilized in connection with such defense, the making available to the indemnifying party of any files, records or other information of the indemnified party that the indemnifying party considers relevant to such defense and the making available to the indemnifying party of any employees, representatives or agents of the indemnified party; provided, however, that in connection therewith the indemnifying party agrees to use reasonable efforts to minimize the impact thereof on the operations of the indemnified party and further agrees to maintain the confidentiality of all files, records, and other information furnished by the indemnified party. In no event shall the obligation of the indemnified party to cooperate with the indemnifying party as set forth in the immediately preceding sentence be construed as imposing upon the indemnified party an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification; provided, however, that the indemnified party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense. The indemnifying party agrees to keep any such counsel hired by the indemnified party informed as to the status of any such defense, but the indemnifying party shall have the right to retain sole control over such defense.

(d) The date on which written notification of a claim for indemnification is received by the indemnifying party shall determine whether such claim is timely made.

(e) In determining the amount of any loss, cost, damage or expense for which a Person is entitled to indemnification under this Contribution Agreement, the gross amount of any such indemnification will be reduced by (i) any insurance proceeds realized by the indemnified Person, and such correlative insurance benefit shall be net of any incremental insurance premiums that become due and payable by the indemnified Person as a result of such claim and (ii) all amounts recovered by the indemnified Person under contractual indemnities from third Persons.

ARTICLE VIII

All personal pronouns used in this Contribution Agreement, whether used in the masculine, feminine or neuter gender, shall include all other genders, and the singular shall include the plural and vice versa. The use herein of the word “including” following any general statement, term or matter shall not be construed to limit such statement, term or matter to the specific items or matters set forth immediately following such word or to similar items or matters, whether or not non-limiting language (such as “without limitation”, “but not limited to”, or words of similar import) is used with reference thereto, but rather shall be deemed to refer to all other items or matters that could reasonably fall within the broadest possible scope of such general statement, term or matter.

Section 8.7 Severability. If any of the provisions of this Contribution Agreement are held by any court of competent jurisdiction to contravene, or to be invalid under, the laws of any political body having jurisdiction over the subject matter hereof, such contravention or invalidity shall not invalidate the entire Contribution Agreement. Instead, this Contribution Agreement shall be construed as if it did not contain the particular provision or provisions held to be invalid and an equitable adjustment shall be made and necessary provision added so as to give effect to the intention of the Parties as expressed in this Contribution Agreement at the time of execution of this Contribution Agreement.

Section 8.8 Amendment or Modification. This Contribution Agreement may be amended or modified from time to time only by the written agreement of all the Parties; provided, however, that Atlas Energy may not, without the prior approval of the Atlas Energy conflicts committee, agree to any amendment or modification that, in the reasonable discretion of Atlas Energy, will adversely affect the holders of Atlas Energy common units. Each such instrument shall be reduced to writing and shall be designated on its face as an Amendment to this Contribution Agreement.
