REASONABLY SATISFACTORY TO THE ISSUER) TO THE EFFECT THAT REGISTRATION IS NOT REQUIRED UNDER SUCH ACT AND LAWS OR AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE.

ii.

Independent Investigation. SES is (or its advisor is) experienced and knowledgeable in the oil and gas business and aware of the risks of that business, including the risks relating to an investment in Common Stock of MHR. SES has conducted its own independent review and analysis of MHR and such Common Stock and acknowledges that SES has satisfactory access to information about MHR. In entering into this Agreement, SES has relied solely upon its own investigation and analysis and the representations, warranties and covenants of MHR as set forth in this Agreement, and SES:

	1)		acknowledges and agrees that SES has not been induced by and has not relied upon any representations, warranties or statements, whether express or implied, made by MHR or any of its directors, officers, shareholders, employees, affiliates, controlling persons, agents, advisors or representatives that are not expressly set forth in this Agreement or the Applicable Agreements, whether or not any such representations, warranties or statements were made in writing or orally; and

	2)		acknowledges and agrees that neither MHR nor any of its directors, officers, shareholders, employees, affiliates, controlling persons, agents, advisors or representatives make or have made any representation or warranty, either express or implied, as to the accuracy or completeness of any of the information provided to SES or its directors, officers, employees, affiliates, controlling persons, agents or representatives.

Note Receivable.

Subject to receipt of the consent of the NGAS Lender Group (the “Lender Consent”), which NGAS shall use commercially reasonable efforts to obtain, but at no cost or expense to NGAS, NPC shall defer all payments of principal and interest due under the Note with respect to the period between January 1, 2011 through the earlier of the (i) Closing Date or (ii) Termination Event (as defined in Section 10 herein) (the “Deferral Period”) (such deferred principal and interest being referred to herein as the “Deferred Amount”). In the event the Lender Consent is not obtained prior to Closing, then within one (1) business day following the Closing Date, NPC shall reimburse SES, by wire transfer of immediately available funds, for all amounts paid by SES under the Note during the Deferral Period. At and subject to the occurrence of Closing, NPC shall cancel, and forgive any and all outstanding amounts under, the Note.

If a Termination Event occurs, then the entire Deferred Amount shall be paid by SES to NPC by wire transfer of immediately available funds within two (2) business days after such event.

Drilling Commitment.

	a.		Subject to the occurrence of Closing, MHR and NGAS agree that they shall cause MHR, NPC and their respective Affiliates, to spend, in the aggregate, a minimum of $20 million (net of general, administrative, and supervision costs) during the remainder of calendar year 2011 subsequent to Closing and a minimum of $20 million (net of general, administrative, and supervision costs) during calendar year 2012 on commencing drilling and the actual completing of new horizontal gas xxxxx during each such calendar year, on the Committed Reserve Area, as defined in the NAESB Purchase Agreement (including operations to rework, sidetrack, deepen, recomplete or plug back such new horizontal gas xxxxx) (“*New Well Drilling Expenditures*”). In the event drilling commences on a new horizontal gas well in either calendar year 2011 or calendar year 2012 and such well is actually completed in the first sixty (60) days of calendar year 2012 or the first forty-five (45) days of calendar year 2013, the costs of the actual drilling and completing of such well shall be credited to the minimum of the applicable calendar year and captured in the applicable Annual Statement described below. Further, credit against the 2011 minimum will also be provided for the cost of the actual drilling and completing of new horizontal gas xxxxx by MHR, NPC and their respective Affiliates during calendar year 2011, but prior to Closing, where the drilling activity on a well commenced on or after January 1, 2011 and where prior to Closing SES receives a schedule and supporting documentation (including, but not limited to third party invoices), together with a certification by an authorized officer, of the actual out of pocket costs for drilling and completing of such new horizontal gas as of Closing. For the avoidance of doubt and notwithstanding the completion date, in no event shall such new horizontal gas xxxxx be considered “Existing Xxxxx” as such term defined in the Gathering Agreement.

	b.		Within ninety (90) days after the end of calendar year 2011 and seventy-five (75) days after the end of calendar year 2012, MHR shall provide SES with a statement of the total New Well Drilling Expenditures by MHR, NPC and its Affiliates during such year (“*Annual Statement*”). For each year in which such New Well Drilling Expenditures are less than $20 million, within ninety (90) days after the end of calendar year 2011 and seventy-five (75) days after the end of calendar year 2012, MHR shall pay to SES, by wire transfer of immediately available funds, as the Seminole Parties’ sole and exclusive remedy, an amount equal to the product of (i) the difference between $20 million and actual New Well Drilling Expenditures during such year and (ii) fifteen percent (15.0%).

	c.		MHR shall, for two (2) years after the end of each such calendar year, maintain records and other evidence sufficient to accurately and properly reflect the New Well Drilling Expenditures. Upon not less than five (5) business days’ prior

notice to MHR, SES and its representative shall have access to such records in the applicable offices of MHR or its affiliates during MHR’s normal business hours, including the right to make copies thereof at SES’s expense, for the purpose of auditing and verifying the accuracy of any Annual Statement. Any such audits performed by or on behalf of SES shall be at SES’s sole cost and expense.

No less than five (5) business days prior to the Option Termination Date, MHR shall deliver to SES a draft settlement statement setting out the fee (the “Option Fee”) which shall be an amount equal to 50% of the actual out of pocket costs and expenses incurred by MHR or its Affiliates as of that date, directly relating to the acquisition, construction, design and installation of the Marcellus Gas Processing Plant, including, without limitation, land acquisition costs, associated equipment costs, broker’s fees, consultant fees, design costs, and engineering, procurement, installation and construction costs (collectively, “Plant Costs*”); provided, that in no event, shall the foregoing actual out of pocket costs and expenses, including, but not limited to land acquisition costs, include any costs associated with the acquisition of any mineral interests. Within five (5) business day following execution of this Agreement, MHR shall provide SES a preliminary draft settlement statement setting forth the estimated Option Fee, including the Plant Costs incurred as of the execution of this Agreement. In the event SES elects, in its sole discretion, not to exercise the Option, then MHR shall pay to SES $300,000.00 by wire transfer in immediately available funds within ten (10) business days following the earlier of (i) receipt by MHR of written notice of such election or (ii) the Option Termination Date; provided, however, MHR shall not be obligated to make such $300,000.00 payment unless and until either (a) the Closing Date or (b) a Termination Event (as defined in Section 10 hereof) shall have occurred due to a material breach of MHR’s representations and warranties or covenants under the Arrangement Agreement.

	c.		Option Exercise. SES may exercise the Option (i) if SES and MHR have agreed in writing on the principal terms of an operating and ownership agreement, which will address the parties’ respective rights, obligations, liabilities and duties with

MHR shall warrant title to the assigned interest to be free of liens, claims and encumbrances arising by, through or under MHR, but not otherwise, but SES shall have full rights of substitution and subrogation into fifty percent (50%) of all warranties previously given to MHR with respect to the Marcellus Gas Processing Plant. The Joint Plant Agreement shall (i) designate MHR or one of its Affiliates as operator of the Marcellus Gas Processing Plant (ii) provide that MHR shall have sole discretion in making decisions concerning all material matters related to the Marcellus Gas Processing Plant, including but not limited to selecting the site location, plant design, natural gas liquids storage and logistics, and downstream pipeline interconnections, although MHR will consider SES’s input in making decisions on such matters, and (iii) provide that SES shall bear 50% of the Plant Costs incurred after the Option Closing.

	d.		Due Diligence.

If SES does not exercise the Option for any reason, it shall return all Plant Records to MHR within three (3) days of the Option Termination Date. In addition, subject to MHR’s access rights, MHR shall grant SES, to the extent permitted, access to the Marcellus Gas Processing Plant in order that SES may conduct an in-person inspection thereof. SES may not, without the prior written consent of MHR,

			conduct any borings or any other invasive tests or examinations with respect to the Marcellus Gas Processing Plant. SES shall provide MHR at least forty-eight (48) hours’ prior notice of any such inspection, and MHR’s representative(s) shall have the right to witness all such inspections.

Non-Economic Conditions; Termination. For purposes of this Agreement, a “Non-Economic Condition” shall be deemed to exist if over any one year period after the Effective Date the actual and documented operating expenses (excluding overhead, except for overhead to SES by NPC charged under the NPC Operating Agreement) incurred by the Gathering Asset Owners in connection with the operation of the Gathering Assets, insofar and only insofar as such expenses are allocable to NPC and its Affiliates, exceeds the sum of all Gathering Fees, other fees and expense reimbursements received by the Gathering Asset Owners under the Applicable Agreements. In the event of a Non-Economic Condition and the Seminole Parties’ belief that such Non-Economic Condition shall continue, the Seminole Parties may notify the other Parties of the Non-Economic Condition (such notice being referred to herein as a “Notice of Non-Economic Condition”) and request amendments of the Applicable Agreements in order to eliminate the Non-Economic Condition. The Seminole Parties may not deliver more than one (1) Notice of Non-Economic Condition per year. Within thirty (30) days after receipt of a Notice of Non-Economic Condition, MHR Parties may request, and upon receipt of such request, the Seminole Parties shall provide the MHR Parties such information as may be reasonably requested by the MHR Parties so that such MHR Parties may evaluate the Seminole Parties’ claim of Non-Economic Condition (the “Information”). MHR shall have thirty (30) days after receipt of the Information to provide to SES a written notice of MHR’s objection to the Seminole Parties’ determination of a Non-Economic Condition (the “Notice of Objection”). If MHR timely submits a Notice of Objection, the Parties shall proceed under Section 8(a) below, and if MHR fails to timely submit a Notice of Objection, the Parties shall proceed under Section 8(b) below.

During the thirty (30) day period following SES’s receipt of the Notice of Objection, the Parties shall attempt in good faith to resolve any differences with respect to the Seminole Parties’ determination of a Non-Economic Condition, including, to the extent applicable, good faith negotiations to amend any of the Applicable Agreements. If the Parties are unable to fully resolve such differences within such time period, the Parties shall submit the dispute to Xxxxx Xxxxxxxx LLP or such other independent accounting firm upon which the Parties mutually agree, for resolution. Promptly, but not less than twenty (20) days after submission to it of the dispute, the independent accounting firm will determine

			those matters in dispute and will render a written report as to the disputed matters and the resulting conclusion supporting or rejecting the Seminole Parties’ determination of a Non-Economic Condition (the “*Report”), which Report shall be conclusive and binding upon the Parties. The fees and expenses of the independent accounting firm shall be paid one-half by SES and one-half by MHR. The Parties shall fully cooperate with the independent accounting firm, including the prompt submission of any information and documents reasonably requested by such firm to render the Report. If the Report supports the Seminole Parties’ determination of a Non-Economic Condition, for a period of thirty (30) days following receipt thereof, the Parties shall negotiate in good faith to reach agreement regarding amendments of the Applicable Agreements to address the Non-Economic Condition (the “Disputed Renegotiation Period*”).

	b.		During the thirty (30) day period following receipt of the Information, the Parties shall negotiate in good faith to reach agreement regarding amendments of the Applicable Agreements to address the Non-Economic Condition (the “*Renegotiation Period*”).

	c.		If, as applicable, the Parties do not enter into written amendments of one or more of the Applicable Agreements during the Renegotiation Period under Section 8(b) or the Disputed Renegotiation Period under Section 8(a) to address the Non-Economic Condition then, notwithstanding any provision of any of the Applicable Agreements, the Seminole Parties may, upon thirty (30) days’ prior written notice to the other Parties (such notice to be delivered no later than within thirty (30) days after the end of the Renegotiation Period or Disputed Renegotiation Period), terminate all (but not less than all) of the Applicable Agreements (the “*Non-Economic Termination*”). To the extent applicable, if the Report rejects the Seminole Parties’ determination of a Non-Economic Condition under Section 8(a), the Applicable Agreements shall continue in full force and effect. In the event of a Non-Economic Termination any of the MHR Entities’ obligations under Section 6 of this Agreement shall immediately terminate.

9.		Indemnity. MHR shall indemnify, defend and hold each of the Seminole Parties and their respective shareholders, members, officers, directors, managers, employees, agents, representatives, contractors, successors, and assigns, harmless from and against all Claims asserted by third parties arising from or related to the Arrangement Agreement or any of the MHR Entities’ operations or activities after the Effective Date under, or relating to, any of the Applicable Agreements. Notwithstanding the foregoing, if any of the Applicable Agreements provide that the Seminole Parties shall indemnify any of the MHR Entities for any reason such provision shall not be deemed to be superseded by any provision of this Agreement.

10.		Termination. In the event (a) the Arrangement Agreement is terminated prior to Closing, or (b) Closing has not occurred by April 30, 2011 (each, a *“Termination Event*”), then, except for the provisions of Section 5, Section 7(d) and Section 11 hereof, which shall survive the Termination Event, this Agreement and each of the Amendments shall be void and of no force and effect, and no Party shall have any obligation or liability hereunder.

		In the event a Termination Event occurs due to a material breach by MHR of its representations and warranties or covenants under the Arrangement Agreement, then, in consideration of the investment of time, effort and expense by the Seminole Parties in the negotiation of, and due diligence in connection with, this Agreement and the Amendments, MHR shall pay to SES its reasonable, properly documented out of pocket costs and expenses, including legal fees, incurred in connection with the negotiation, preparation and execution of this Agreement and the Amendments (the “*Transaction Expenses*”). The Seminole Parties agree that upon receipt of the Transaction Expenses, MHR shall have no further obligation or liability hereunder and the Seminole Parties shall not be entitled to any additional legal or equitable remedy under this Agreement as a result of such Termination Event or otherwise.

11.		Confidentiality. To the extent not already in the public domain through no fault or breach of the terms of this Agreement by the Seminole Parties, all information furnished by MHR to SES in connection with this Agreement and in the course of its due diligence examination of the Marcellus Gas Processing Plant, including without limitation the Plant Records and the results of SES’s due diligence with respect to environmental matters (collectively, the “*Confidential Information*”) shall be confidential property of MHR and shall not be shared, exhibited or divulged to third parties without MHR’s prior written consent, except to the extent disclosure is required by law. The Confidential Information may be disclosed to SES’s affiliates and SES’s and its affiliates’ respective consultants, attorneys, lenders and other representatives, only to the extent such disclosure is reasonably necessary in order to consummate the transactions contemplated by this Agreement, provided that such persons and entities are bound by this provision.

12.		Press Releases; Announcements. The initial press release with respect to the execution of this Agreement shall be issued by MHR in a form to be reasonably agreed upon by MHR and the Seminole Parties. Thereafter, neither Party shall issue or cause the publication of any press release or other public announcement or make any other disclosure with respect to this Agreement, the terms hereof or the transactions contemplated hereby without the prior consent of the other Party (which consent shall not be unreasonably withheld or delayed), except (i) as contemplated by the terms of this Agreement and to perform any actions permitted hereunder, or (ii) as may be required by Law or by any applicable listing agreement with a national securities exchange as determined in the good faith judgment of the Party proposing to make such release (in which case, such Party shall not issue or cause the publication of such press release or other public announcement without prior consultation with the other Party, to the extent practicable). Notwithstanding anything contained herein to the contrary, any of the MHR Entities may disclose the terms of this Agreement and the transactions contemplated thereby in connection with any required filing under the Securities and Exchange Act of 1934, as amended, and in the proxy statement to be distributed to the NGAS shareholders as contemplated by the Arrangement Agreement. MHR shall be responsible for any breach of this Section 12 by any of the MHR Entities.
