Section 2.1 Petro-Technical Services.

(a) During the Term, except as terminated earlier pursuant to Section 6.1, (i) Atlas agrees to provide the Petro-Technical Services for the Petro-Technical Wells, and (ii) AHD agrees to pay the applicable Petro-Technical Services Fee for each such Petro-Technical Service provided.

(b) The Petro-Technical Services may be directly provided by Atlas or may be provided through any of its Affiliates or subcontractors, and the Petro-Technical Services shall be provided to such AHD Group member as may be designated from time-to-time by AHD.

(c) Subject to Section 2.6, all Petro-Technical Services provided by Atlas and its Affiliates and subcontractors hereunder shall be performed using commercially reasonable efforts, skill and judgment. Without limiting the foregoing, all Petro-Technical Services shall be provided in a timely and professional workmanlike manner, consistent with applicable Law and standards or principles governing the Petro-Technical Services.

(d) Atlas shall be entitled to a fee for the Petro-Technical Services it performs under this Agreement (the “Petro-Technical Services Fee”) representing the actual costs (both direct and incidental) incurred by Atlas, its Affiliates or subcontractors, in the performance of the Petro-Technical Services, but in no event shall such costs exceed market-based rates in the following geographic and surrounding areas: Pittsburgh, Pennsylvania, as to the Petro-Technical Wells located in Pennsylvania; and Traverse City, Michigan, as to the Petro-Technical Wells located outside of Pennsylvania, in each case for the provision of the same or similar services.

Section 2.2 Monthly Invoices. Atlas shall invoice AHD on a monthly basis for all Petro-Technical Services provided during the prior month. Such invoices shall identify the applicable Petro-Technical Services provided for such month, on a work-order basis as set forth in Schedule 2.1, and the Petro-Technical Services Fees payable for each such Petro-Technical Service. All invoices shall be due and payable thirty (30) days from the date AHD receives the applicable invoice (the “Due Date”).

Section 2.3 Payment Disputes. Payment of any invoice shall not prejudice the right of AHD to protest or question the correctness thereof; provided however, all invoices rendered to AHD by Atlas during any calendar year shall conclusively be presumed to be true and correct after six (6) months following the end of any such calendar year, unless within said six (6) month period AHD disputes any invoice or portion thereof, by providing Atlas written notice of the disputed amounts, together with a statement of the particulars of the dispute, including the calculations with respect to any errors or inaccuracies claimed. No adjustments favorable to AHD shall be made unless the foregoing time requirements have been satisfied. AHD shall not be entitled to withhold any such disputed amounts. The forgoing payment dispute and adjustment process shall be the exclusive remedy for addressing payment disputes between the Parties.

Section 2.4 Changes; Termination Of Services.

(a) The Parties may, at any time during the Term, mutually agree in writing to change the nature, extent or duration of performance of any or all Petro-Technical Services hereunder.

(b) If AHD should in its sole discretion, at any time during the Term, cease to require Atlas or any of its Affiliates or subcontractors to undertake any part of the Petro-Technical Services (the “Cancelled Services”), AHD may give written notice to such effect to Atlas. Atlas and its Affiliates and subcontractors shall, as soon as reasonably practicable following the receipt of such notice, cease to provide the Cancelled Services.

Section 2.5 Project Managers. Atlas and AHD shall each appoint an individual to act as its project manager to deal with issues arising out of the performance of this Agreement, and such individuals shall discuss such issues as often as reasonably necessary in order to facilitate the orderly provision of the Petro-Technical Services by Atlas. The initial project managers are set forth on Schedule 2.5.

Section 2.6 Compliance with Laws and Governmental Requirements. Notwithstanding anything to the contrary in this Agreement, Atlas shall comply (and cause each Affiliate or subcontractor providing any of the Petro-Technical Services to comply) with (i) all Laws applicable to the provision by it (or such Affiliate or subcontractor) of the Petro-Technical Services hereunder; and (ii) the accounting and reporting requirements of any Governmental Entity having jurisdiction over it or its Affiliates or subcontractors with respect to their respective activities related to Atlas’ or its Affiliates’ or subcontractors’ performance of the Petro-Technical Services.

Section 2.7 Third-Party Limitations. Each Party acknowledges and agrees that the Petro-Technical Services provided by Atlas through third parties or using third party Intellectual Property are subject to the terms and conditions of any applicable agreements between Atlas and such third parties. Atlas shall use commercially reasonable efforts to (i) obtain any necessary consents from such third parties in order to provide such Petro-Technical Services or (ii) if any such consent is not obtained, provide acceptable alternative arrangements to provide the relevant Petro-Technical Services sufficient for AHD’s and Resource’s purposes. All costs associated with (i) and (ii) above shall be borne by AHD or Resources, as applicable; provided that such costs shall not be incurred without the prior written consent (which may be provided by electronic mail) of AHD or Resources, as applicable. If any such acceptable alternative arrangement is not reasonably available or AHD or Resources, as applicable, does not consent in writing to pay such additional costs, the Parties shall negotiate in good faith reasonable modifications of the Petro-Technical Services such that such consents are not required for the performance of such affected Petro-Technical Services or, if after such good-faith negotiation the Parties are unable to agree upon such modifications, Atlas shall not be required to provide such Petro-Technical Service.

ARTICLE III

OPERATOR’S INSURANCE

Section 3.1 Atlas’ Insurance. So long as Atlas is providing Petro-Technical Services under this Agreement, Atlas shall obtain and maintain at its own expense (a) all required workmen’s compensation insurance and comprehensive general public liability insurance in amounts and coverage not less than $1,000,000 per person per occurrence for personal injury or death and $1,000,000 for property damage per occurrence. Subject to the above limits, Atlas’ general public liability insurance shall be in all respects comparable to that generally maintained in the industry with respect to services of the type to be rendered and activities of the type to be conducted under this Agreement. The insurance required to be provided by Atlas pursuant to this Section 3.1 shall, if permitted by such entity’s insurance carrier:

(a) name AHD and the applicable AHD Group member as additional insureds; and

(b) provide that at least thirty (30) days’ prior notice of cancellation and any other adverse material change in the policy shall be given to AHD and the applicable AHD Group member.

However, AHD shall, or shall cause the applicable AHD Group member to, reimburse Atlas for the additional cost, if any, of including it as an additional insured party under Atlas’ insurance. Current copies of all policies or certificates of Atlas’ insurance coverage shall be delivered to AHD on request. It is understood and agreed that Atlas’ insurance coverage may not adequately protect the interests of AHD and that AHD shall carry at its expense the excess or additional general public liability, property damage, and other insurance, if any, as it deems appropriate.

NOTWITHSTANDING THE FOREGOING, and without limitation of the provisions set forth in Article IV herein, Atlas may provide AHD with certification of self-insurance for the insurance and endorsements required under this Section 3.1; provided, that none of AHD, or any applicable AHD Group entity shall be entitled to file claims under this Agreement against Atlas’ self-insurance for any reason whatsoever.

Section 3.2 Subcontractors’ Insurance. Atlas shall require all of its subcontractors to carry all required insurance that is otherwise required of Atlas pursuant to Section 3.1 with respect to the Services such subcontractor is solicited to provide.

Section 6.10 Subcontractors. Atlas may hire or engage one or more subcontractors to perform any or all of its obligations under this Agreement; provided, however, that (i) Atlas shall use the same degree of care in selecting any such subcontractor as it would if such contractor was being retained to provide similar services to Atlas and (ii) Atlas shall in all cases remain primarily responsible for all of its obligations under this Agreement with respect to the scope of the Petro-Technical Services, the standard for services as set forth in Article II and the content of the Petro-Technical Services provided under this Agreement.

Section 6.11 Severability. If any term or other provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. The Parties further agree that if any provision contained herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing this Agreement, they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by applicable Law and, to the extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the Parties to the greatest extent legally permissible.

In the event of any conflict between this Agreement and the Transaction Agreement, the terms of this Agreement shall control.

Section 6.15 Amendments. No provision of this Agreement, including any Schedules to this Agreement, may be amended, supplemented or modified except by a written instrument making specific reference to this Agreement or any such Schedules to this Agreement, as applicable, signed by all the Parties.

Except for the provisions of Article IV, which are intended to be enforceable by the Persons respectively referred to therein, this Agreement is for the sole benefit of the Parties and their permitted successors and assigns and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person, including any union or any employee or former employee of Atlas or AHD, any legal or equitable right, benefit or remedy of any nature whatsoever, including any rights of employment for any specified period, under or by reason of this Agreement.

Section 6.17 Governing Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Pennsylvania, without regard to any conflicts of law rules (whether of the Commonwealth of Pennsylvania or of any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the Commonwealth of Pennsylvania. 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 (whether brought by any Party or any of its Affiliates or against any Party or any of its Affiliates) shall be brought only in the Pennsylvania Court of Common Pleas or, if such court shall not have jurisdiction, any federal court located in the Commonwealth of Pennsylvania or other Pennsylvania 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 6.7 shall be deemed effective service of process on such Party.

12

Section 6.18 Dispute Resolution.
