WITNESSETH:

WHEREAS, on April 4, 2007, Trans Energy and RP6 entered into that certain Farm-Out and Area of Joint Development Agreement (the “Original AJDA”).

WHEREAS, on July 16, 2010, pursuant to a Purchase and Sale Agreement (the “2010 PSA”), Trans Energy sold to REV a 50% interest in certain acreage in Marion and Tyler Counties, West Virginia. REV has since asserted that certain of the properties sold to it pursuant to the 2010 PSA have title defects resulting in a diminution in value for which REV is entitled to compensation from Trans Energy.

WHEREAS, on March 31, 2011, Trans Energy entered into a Purchase and Sale Agreement (the “2011 PSA”) with REV, pursuant to which Trans Energy sold to REV certain oil and gas leases and interests located in Marion, Marshall, Tyler and Wetzel Counties, West Virginia. REV has since asserted that certain of the properties sold to it pursuant to the 2011 PSA have title defects resulting in a diminution in value for which REV is entitled to compensation from Trans Energy.

WHEREAS, on April 26, 2012, Trans Energy and RP6 amended and restated the Original AJDA (the “Restated AJDA”) to, among other things, supersede the Original AJDA and add American Shale, REV and RP8, and for certain limited purposes therein, RP7, REO and Sancho Oil and Gas Corporation, a West Virginia corporation, as parties under the Restated AJDA.

WHEREAS, on May 21, 2014, American Shale entered into a Purchase and Sale Agreement (the “2014 PSA”) with REV, pursuant to which American Shale sold to REV (i) an undivided interest across all of its undeveloped leasehold, (ii) an over-riding royalty interest of 1.5% in all of its leasehold in Wetzel County, West Virginia, and (iii) an over-riding royalty interest of 1.0% in six wells in Marshall County, West Virginia. In connection with the 2014

PSA, REV, RP6 and American Shale amended the Restated AJDA pursuant to that certain First Amendment to Amended and Restated Farm-Out and Area of Joint Development Agreement dated May 20, 2014 (the “First Amendment,” and the Restated AJDA, as amended by the First Amendment, the “AJDA”). Under the AJDA, among other things, (a) REV agreed to fund all costs associated with certain leasehold acquisitions made pursuant to the AJDA subsequent to April 1, 2014 (such leasehold acquisitions, the “Subject Properties”), and (b) in the event that REV sold its interest in any such Subject Properties, American Shale was granted the right to buy a 25% interest in any Subject Property at REV’s cost, plus interest accrued thereon at the rate of 12% per annum (the “Purchase Option”), simultaneously with the consummation of such sale by REV.

WHEREAS, pursuant to the AJDA, each party thereto has certain rights, including a pre-emptive right and a tag-along right, upon a sale or farm-out by any other party thereto of its interests under the AJDA, each as more fully set forth in Section 9 of the AJDA (the “AJDA Rights”).

WHEREAS, Trans Energy, American Shale and the members of the Republic Group previously entered into that certain Joint Operating Agreement, dated as of April 4, 2007, as amended on June 17, 2011 and April 26, 2012 (as amended, the “JOA”). Under the JOA, each of Trans Energy, American Shale and the members of the Republic Group have a right of first refusal, tag-along right and certain other rights upon a sale or farm-out of an interest covered by the JOA by any other party thereto or such other party’s affiliate assignee, each as more fully set forth in Section XV.F thereof (the “JOA Rights”).

WHEREAS, on April 26, 2012, REO and Trans Energy entered into that certain Contract Operator Agreement (the “Contract Operator Agreement”) pursuant to which Trans Energy was subcontracted to perform certain functions as the operator of the properties and assets subject to and covered by the AJDA and the JOA.

WHEREAS, on April 26, 2012, pursuant to the AJDA and the JOA, REO was appointed as Operator (as such term is defined in the JOA) under the JOA and operator under the AJDA (in each such capacity, the “Operator”) of the properties subject to the JOA and AJDA, as applicable, and subject to Trans Energy’s right to re-assume its position as Operator under the AJDA and the JOA in certain circumstances. On May 20, 2014, as set forth in the First Amendment, Trans Energy relinquished its right to re-assume its position as Operator.

WHEREAS, on the date hereof, the Republic Group and Production entered into a Purchase and Sale Agreement (the “Republic PSA”) pursuant to which the Republic Group will sell substantially all of its oil and gas properties, including the Subject Properties, to Production (collectively, the “Republic/EQT Transaction”), which such sale shall trigger the Purchase Option with respect to the Subject Properties and, in respect of Trans Energy and American Shale, the AJDA Rights and the JOA Rights.

WHEREAS, on the date hereof, Trans Energy entered into an Agreement and Plan of Merger (the “TE Merger Agreement”) with EQT and Merger Sub pursuant to which Merger Sub will make a tender offer for all of the outstanding shares of common stock of Trans Energy and, if such tender offer is successfully consummated, following such consummation, Merger

2

Sub will be merged with and into Trans Energy, with Trans Energy surviving as a wholly owned subsidiary of EQT (such transactions referred to together as the “TE/EQT Transaction” and, collectively with the Republic/EQT Transaction, the “Transactions”).

WHEREAS, if each of the Transactions is successfully consummated, as a result of the consummation of each Transaction (each, a “Closing,” and together, the “Closings”), the EQT Group will, either directly or indirectly, own all of the outstanding properties and assets currently covered by the AJDA.

WHEREAS, the Republic Group contemplates that concurrently with the Closings it will offer employment on a temporary basis to each member of the land department at Trans Energy (the “Land Group”) as of the date hereof.

WHEREAS, the TE Group and the Republic Group desire to settle finally and forever any and all claims between them of any nature whatsoever from any and all liability or damages of any kind, known or unknown, in contract or in tort, arising out of their dealings with each other prior to the Closings, including the transactions described in the Recitals above.
