Item 1.01. Entry into a Material Definitive Agreement

On February 13, 2014, ARP Mountaineer Production, LLC (“ARP Mountaineer”), a wholly owned subsidiary of Atlas Resource Partners, L.P. (the “Partnership”), entered into a definitive Asset Purchase Agreement (the “Purchase Agreement”) with GeoMet, Inc. (“GeoMet”), GeoMet Operating Company, Inc. (“Operator”), and GeoMet Gathering Company, LLC (“Gathering” and, together with GeoMet and Operator, the “Sellers”).

The Purchase Agreement provides for the acquisition (the “Acquisition”) of all of Sellers’ coalbed methane assets in the Appalachian Basin in Virginia and West Virginia (the “Assets”). The Acquisition constitutes a sale of substantially all of the Sellers’ assets, and, therefore, a vote of the GeoMet stockholders is required to approve the Acquisition. Subject to the terms and conditions of the Purchase Agreement, ARP Mountaineer will acquire the Assets for $107 million, with an effective date of January 1, 2014. The purchase price will be reduced by the amount of proceeds received by Sellers with respect to the Assets from the period beginning on January 1, 2014 through the closing, and increased by the amount of operating and certain other expenses incurred by Sellers with respect to the Assets during that period. The purchase price is also subject to other adjustments, including, among others, reductions for, subject to certain exceptions and limitations: the allocated value of certain Assets with respect to which third-party consents are not received prior to closing; the allocated value of certain Assets with respect to which preferential purchase rights are exercised prior to closing; and the value of title defects and environmental defects with respect to the Assets. The Partnership has provided an irrevocable guaranty of ARP Mountaineer’s performance of its obligations under the Purchase Agreement.

The Purchase Agreement contains customary representations and warranties of the parties and covenants of the Sellers to operate the Assets in the ordinary course until the Acquisition is completed, as well as covenants relating to employee matters, among other things. The closing of the Acquisition is subject to certain closing conditions, including the GeoMet stockholder vote, execution of a services agreement and all documentation required to assign the Assets to ARP Mountaineer. The Purchase Agreement also provides for the parties to indemnify each other with respect to certain matters, subject to certain temporal and financial limitations. The Purchase Agreement includes certain termination rights, including, among others, the right of either party to terminate: if the reduction in the purchase price for title and environmental defects exceeds 15% of the base purchase price; if the reduction in the purchase price for casualty losses exceeds 15% of the base purchase price; or if the closing has not occurred by September 30, 2014. In addition, the Purchase Agreement may be terminated (i) by ARP Mountaineer, if the GeoMet board of directors makes a change in recommendation regarding the Acquisition, (ii) by GeoMet, if the GeoMet board of directors elects to pursue a superior proposal, or (iii) by either ARP Mountaineer or GeoMet, if the GeoMet stockholders do not approve the Acquisition. Under certain circumstances, the termination of the Purchase Agreement will result in the payment of a termination fee to ARP Mountaineer.

The foregoing description of the Purchase Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of such agreement, attached hereto as Exhibit 2.1 to this Current Report, which is incorporated herein by this reference.

Item 7.01. Regulation FD Disclosure

On February 14, 2014, the Partnership issued a press release related to the foregoing. A copy of the press release is attached as Exhibit 99.1 to this Current Report. The information under this item in this Current Report, including the exhibit hereto, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section.

Item 8.01. Other Events.

In connection with the execution of the Purchase Agreement, certain stockholders of GeoMet entered into a Voting Agreement for the benefit of ARP Mountaineer and the Partnership (the “Voting Agreement”). The stockholders that are party to the Voting Agreement own approximately 48.9% of the combined voting power of the common stock and preferred stock (on an as converted basis) treated as a single class and approximately 59.6% of the preferred stock voting power of GeoMet in the aggregate. The Voting Agreement generally requires that the stockholders party thereto vote all of their shares of GeoMet common stock and preferred stock, as applicable, in favor of the Acquisition and against alternative transactions, and generally prohibits them from transferring their shares. The Voting Agreement automatically terminates upon the earliest to occur of (1) the termination of the Purchase Agreement, (2) a change of recommendation by the GeoMet board of directors and (3) the closing of the transactions contemplated by the Purchase Agreement.

The foregoing summary of the Voting Agreement is subject to, and qualified in its entirety by, the full text of the document filed as Exhibit 99.2, which is incorporated herein by reference.

6.5 Defects; Consents; Preferential Rights.

(a) Environmental or Title Defect. In the event between the execution hereof and the end of the Due Diligence Period, Buyer discovers an Environmental Defect or a Title Defect, Buyer shall deliver a written notice of same to Sellers (the “Defect Notice”). The Defect Notice shall clearly indicate the nature of the Environmental Defect or Title Defect and the Assets to which it relates. Sellers shall have the right, but not the obligation, to attempt to cure any Environmental Defect or Title Defect prior to Closing. In the event Sellers do not cure a Title Defect or Environmental Defect prior to Closing, or Sellers dispute the Title Defect or Environmental Defect or the associated Defect Value asserted by Buyer and such dispute has not been finally determined by the Title Consultant or the Environmental Consultant pursuant to Section 6.5(b), Sellers shall have the option of (i) removing the defective Assets from the definition of the “Assets” and the Purchase Price shall be adjusted downward in an amount equal to the Allocated Value of the defective Assets or (ii) delivering such affected Assets to Buyer and proposing a Purchase Price adjustment equal to the Defect Value and if the parties do not agree upon the Defect Value by Closing such dispute shall be resolved as provided in Section 6.5(b) and the sum of the disputed Defect Values shall be paid into an Escrow Account pending resolution thereof under Section 6.5(b). Notwithstanding anything to the contrary, any Title Defect or Environmental Defect with a Defect Value of less than $100,000 shall be deemed waived by Buyer, and in no event shall there be any remedies under this Agreement (pursuant to the special warranty or otherwise) with respect to any Title Defect or Environmental Defect less than such threshold. The reduction to the Purchase Price with respect to all Title Defects affecting Assets Sellers elects to deliver to Buyer pursuant to Section 6.5(a)(ii) shall be subject to a deductible of $2,000,000 and the Purchase Price shall be reduced only by the amount of such Defect Values in excess of such deductible. The reduction to the Purchase Price with respect to all Environmental Defects affecting Assets Sellers elect to deliver to Buyer pursuant to Section 6.5(a)(ii) shall be subject to a deductible of $2,000,000 and the Purchase Price shall be reduced only by the amount of such Defect Values in excess of such deductible.

(b) Failure to agree on Title Defect or Defect Value. If, with respect to Assets affected by a Title Defect or Environmental Defect with respect to which Buyer elects to proceed under Section 6.5(a)(ii), the Parties cannot reach agreement concerning the existence of a Title Defect or Environmental Defect, Sellers’ proposed cure of a Title Defect, a Defect Value, or a Casualty Defect, within twenty (20) Business Days after Closing, then upon either Party’s request, (i) an attorney mutually acceptable to the Parties having at least twenty (20) years of experience in mineral and land title matters (the “Title Consultant”) shall resolve all points of disagreement relating to Title Defects, proposed and actual cures and Defect Values applying standards customarily applied by reasonable and prudent operators of oil and gas properties in the areas where the Assets are located and (ii) an attorney mutually acceptable to the Parties having at least twenty (20) years of experience in environmental matters (the “Environmental Consultant”) shall resolve all points of disagreement relating to Environmental Defects, proposed and actual cures and Defect Values. Each Party shall present a written statement of its position on the Title Defect or Environmental Defect, proposed cure and/or Defect Value in question to the Title Consultant or Environmental Consultant, as applicable, promptly, and the Title Consultant or

23

Environmental Consultant, as applicable, shall make a determination of all points of disagreement in accordance with the terms and conditions of this Agreement within fifteen (15) days of receipt of such position statements. The determination by the Title Consultant or Environmental Consultant, as applicable, shall be conclusive and binding on the Parties with respect solely to disputes between the Parties, and shall be enforceable against any Party in any court of competent jurisdiction; provided that, in no event shall the determination of the Title Consultant or Environmental Consultant exceed the Allocated Value of the assets affected by such Title Defect or Environmental Defect.

Once the Title Consultant’s or Environmental Consultant’s, as applicable, determination has been expressed to both Parties, the Parties shall give joint instructions to the Escrow Agent to disburse the funds deposited in an Escrow Account with respect to the applicable Defect Values in a manner consistent with the determinations of the Title Consultant and the Environmental Consultant. The cost of any such Title Consultant or Environmental Consultant shall be paid one-half by Sellers and one-half by Buyer. If at any time the Title Consultant or Environmental Consultant fails or refuses to perform hereunder, a new Title Consultant or Environmental Consultant shall be promptly chosen by the Parties.

(c) Consents. Sellers shall use their reasonable commercial efforts to obtain all required consents relating to a transfer of the Assets to Buyer. If the failure to obtain such consent would cause (A) the assignment of the Assets affected thereby to the Buyer to be void or (B) the termination of a Lease, or Contract under the express terms thereof or would be reasonably likely to subject Buyer to material damages (a “Hard Consent”), and any such Hard Consents to assign any Asset have not been obtained as of the Closing (other than governmental consents that are customarily obtained after Closing), then (i) the portion of the Assets for which such Hard Consent has not been obtained shall be excluded from the Assets at the Closing and the Purchase Price shall be reduced by the Allocated Value thereof, (ii) Sellers shall use their reasonable commercial efforts to obtain such Hard Consent as promptly as possible following Closing, and (iii) if such Hard Consent is obtained prior to the determination of the Final Adjusted Purchase Price, the Allocated Value of that portion of the Assets, adjusted as provided in Section 3.2, shall be an upward adjustment to the Purchase Price on the Final Settlement Statement, and Sellers shall assign such Asset to Buyer, effective as of the Effective Date, using an assignment substantially in the form of Exhibit A. Buyer shall reasonably cooperate with Sellers in obtaining any required consent.

(d) Preferential Rights. Sellers shall comply with all preferential right to purchase provisions relative to their interest in the Assets by sending notice of this Agreement, within three (3) Business Days after execution of this Agreement, to all persons holding preferential rights, offering to sell to each such person that portion of the Assets for which such a preferential right is held for an amount equal to the Allocated Values of such Assets and subject to all other terms and conditions of this Agreement. If Buyer discovers any additional preferential rights, Buyer shall promptly notify Sellers. If, prior to Closing, any of such persons asserting a preferential purchase right notifies Sellers that it intends to consummate the purchase of that portion of the Assets to which it holds a preferential purchase right pursuant to the terms and conditions of such notice and this Agreement, then such Assets shall be excluded from the Assets identified in this Agreement and the Purchase Price shall be reduced by the Allocated Values of such Assets; provided, however, that if the holder of such preferential right is required to but fails to consummate the purchase of such Assets on or prior to the Closing Date, then Sellers shall notify Buyer, and Sellers shall sell to Buyer, and Buyer shall purchase from Sellers, the Assets to which the preferential purchase right was asserted for the Allocated Values of such Assets. All Assets for which a preferential purchase right has not been asserted prior to Closing, or with respect to which Closing does not occur on or before the Closing Date following the assertion of a preferential purchase right, shall be sold to Buyer at Closing pursuant to the provisions of this Agreement. If one or more of the holders of any preferential purchase rights notifies Sellers subsequent to Closing that it intends to assert its preferential purchase right, Sellers shall give notice thereof to Buyer, whereupon Buyer shall perform all valid preferential

24

purchase right obligations of Sellers to such holders and Buyer shall be entitled to receive (and Sellers hereby assign to Buyer all of Sellers’ rights to) all proceeds received from such holders in connection with such preferential purchase rights.

6.6 Transfer of Books and Records. Not later than thirty (30) days after Closing, Sellers will transfer, convey and deliver to Buyer (to the extent not previously delivered at Closing) originals (or copies if originals are not available) of all of the Sellers’ Books and Records, whether in manual or electronic form, subject to any contractual restrictions with third parties. To each Seller’s Knowledge, such Seller is not a party to any document and none of the Books and Records is subject to any contract which would restrict or otherwise prevent the transfer of all Books and Records in such Seller’s possession, or the possession of such Seller’s agents or representatives, to Buyer. Sellers shall have reasonable access for a period of six (6) months following the Closing during normal business hours for litigation, tax or other legitimate business purpose to the files delivered to Buyer hereunder and in Buyer’s possession (Sellers shall promptly reimburse Buyer for any reasonable out of pocket expenses incurred by Buyer in connection with Sellers’ inspection or review of such files); provided, however, Buyer shall have no obligation to keep or maintain the files or any other records or documents beyond five (5) years after the Closing Date. Except for Well files and Lease files kept in the Ordinary Course of Business, Sellers shall not be obligated to make or deliver any geological or engineering interpretations or explanation of information in the Books and Records. Sellers may make and retain such copies of the Books and Records as Sellers deem necessary for the conduct of their business, and shall after the Closing be permitted to make copies of the Books and Records at their own expense. Sellers agree to allow Buyer access to Sellers’ financial records pertaining to the Assets for the purpose of conducting a financial audit for the prior two (2) year period ending on the Effective Date. Any such audit shall be conducted at Buyer’s sole cost and expense and Sellers agrees to cooperate with Buyer to conduct such audit.

6.7 Taxes. All Taxes shall be pro-rated between Sellers and Buyer as of the Effective Date. Sellers shall be charged for all such Taxes based on ownership of or Production from the Assets prior to the Effective Date. Buyer shall be charged for all such Taxes based on ownership of the Assets from and after the Effective Date. Buyer shall pay all documentary, filing and recording fees for the Assignment required in connection with the transaction contemplated by this Agreement. Additionally, Buyer will bear and pay all state and local government sales taxes incident to the transfer of the Assets, if any are chargeable.

6.8 Purchase Price Allocation. Sellers and Buyer recognize that reporting requirements of §1060(b) of the Code, and the regulations promulgated thereunder, may apply to the transaction contemplated by this Agreement. If so, Sellers and Buyer agree that the Purchase Price shall be allocated among the Assets as mutually agreed by Sellers and Buyer to comply with and satisfy the requirements of §1060(b) and applicable regulations. Sellers and Buyer agree that no Asset shall be allocated a negative value.

6.9 Seller’s Actions Prior to Closing.

(a) No Seller shall, nor shall such Seller authorize or permit any of its Affiliates to, and such Seller shall cause its and its Affiliate’s respective Representatives not to, directly or indirectly (i) initiate, solicit or knowingly encourage (including by way of furnishing information or assistance), or knowingly induce, or take any other action designed to, or that would reasonably be expected to, result in the making, submission or announcement of, any proposal or offer that constitutes an Acquisition Proposal, (ii) enter into any Alternative Acquisition Agreement, (iii) other than informing Persons of the provisions contained in this Section 6.13, enter into, continue or otherwise participate in any discussions or negotiations regarding, furnish to any Person any information or data or access to its properties with respect to, or otherwise cooperate with or take any other action to facilitate, (A) any Acquisition Proposal or (B) or any proposal that by its terms requires Sellers to abandon, terminate or fail to consummate the transactions contemplated by this Agreement or (iv) submit to the GeoMet Stockholders for their approval any Acquisition Proposal, or agree or publicly announce an intention to take any of the foregoing actions.

27

(b) Each Seller shall, and shall cause its Affiliates and its and its Affiliates’ Representatives to, immediately cease and cause to be terminated all existing solicitation, discussions or negotiations conducted by any Seller, such Seller’s Affiliates or any of its or such Seller’s Affiliates’ Representatives with any Persons or their Representatives with respect to any Acquisition Proposal and will request the return or destruction of all confidential information about the Sellers provided by or on behalf of the Sellers that was previously furnished to such Persons since November 14, 2013 in connection with their consideration of any Acquisition Proposal to the extent Sellers are entitled to have such confidential information be returned or destroyed. Sellers shall promptly inform each of their and their Affiliates’ respective Representatives of the obligations undertaken in this Section 6.13. Each Seller agrees not to, and to cause its Affiliates not to, release any third party from the standstill provisions of any agreement (or terminate, amend, modify or waive any such standstill provision of any such agreement) to which such Seller or its Affiliates is or may become a party, shall enforce, to the fullest extent permitted under applicable Legal Requirements, the provisions of any such agreement, including by seeking to obtain injunctions to prevent any breaches of such agreements and to enforce specifically the terms and provisions thereof in any court of the United States of America or any state having jurisdiction, except, in each case, if the GeoMet Board has determined in good faith, after consultation with its outside counsel and financial advisors, that any of the foregoing would be reasonably likely to violate the directors’ fiduciary duties under applicable Legal Requirements.

(c) Notwithstanding anything to the contrary in Section 6.13(a) or Section 6.13(b), prior to the receipt of the Requisite Stockholder Vote the GeoMet Board may, following receipt of and on account of a bona fide written unsolicited Acquisition Proposal (so long as the GeoMet Board, in receiving such Acquisition Proposal, has otherwise complied in all material respects with the terms of Section 6.13(a) and Section 6.13(d) with respect to such Acquisition Proposal):

(i) furnish information with respect to Sellers to the Person making such Acquisition Proposal and its Representatives pursuant to and in accordance with an Acceptable Confidentiality Agreement (a copy of which shall be provided to Buyer promptly after its execution) containing confidentiality restrictions that are no less restrictive to such Person than those contained in the Confidentiality Agreement are to Buyer, provided that such Acceptable Confidentiality Agreement shall not contain any provisions that would prevent Sellers from complying with its obligation to provide the required disclosure to Buyer pursuant to Section 6.13(d) and Section 6.13(e), and Sellers shall promptly provide Buyer with any non-public information concerning the Sellers’ business, present or future performance, financial condition, or results of operations provided to any third party, to the extent such information has not been previously provided to Buyer; and

(ii) participate in discussions or negotiations with such Person or its Representatives regarding such Acquisition Proposal;

provided, in each case, prior to taking such actions referred to in Section 6.13(c)(i) or Section 6.13(c)(ii) the GeoMet Board determines in good faith, after consultation with outside legal counsel and financial advisors, that (A) the failure to take such action would be inconsistent with its fiduciary duties under applicable Legal Requirements and (B) such Acquisition Proposal constitutes a Superior Proposal.

(d) Sellers shall promptly (and in any event within twenty-four (24) hours) provide (i) written notice to Buyer of receipt or delivery of any Acquisition Proposal, which notice shall identify the name of the Person making such Acquisition Proposal, and (ii) a copy of any such Acquisition Proposal, if made in writing, or a written summary of the material terms and conditions of such Acquisition Proposal, if not made in writing. Sellers shall (i) promptly keep Buyer reasonably informed of the status and material terms and conditions of any such Acquisition Proposal (including any changes

28

to such material terms and conditions), and (ii) promptly (and in any event within twenty-four (24) hours) upon receipt or delivery thereof, provide Buyer with copies of (A) all written materials provided to Sellers or any of their Representatives by the Person making such Acquisition Proposal or any of its Representatives that describe any material terms and conditions of such Acquisition Proposal (or that describe any subsequent changes to such material terms and conditions) and (B) all drafts and final versions of agreements (including schedules and exhibits thereto) relating to any Acquisition Proposal exchanged between any Seller or such Seller’s Representative, on the one hand, and the Person making such Acquisition Proposal or any of its Representatives, on the other hand.

(e) Except as permitted by this Section 6.13(e), neither the GeoMet Board nor any committee thereof shall (i) withdraw (or modify or qualify in any manner adverse to Buyer), or resolve to or publicly propose to withdraw (or modify or qualify in a manner adverse to Buyer), the GeoMet Board Recommendation or otherwise take any action or make any public statement in connection with the transactions contemplated by this Agreement that is inconsistent with the GeoMet Board Recommendation, (ii) adopt, approve, endorse or recommend, or resolve to or publicly propose to adopt, approve, endorse or recommend, any Acquisition Proposal (any of the foregoing actions in clauses (i) and (ii), a “Change of Recommendation”) (it being agreed that a “stop, look and listen” communication by GeoMet Board to the GeoMet Stockholder pursuant to Rule 14d-9(f) of the Exchange Act shall not constitute a Change of Recommendation) or (iii) adopt, approve, endorse or recommend, or resolve to or publicly propose to adopt, approve, endorse or recommend, or allow any Seller or such Seller’s Affiliates to execute or enter into, any binding or non-binding letter of intent, option, joint venture, partnership or other arrangement or understanding in connection with any Acquisition Proposal (other than confidentiality agreements permitted under Section 6.3(c) pursuant to and in accordance with the limitations set forth therein). Notwithstanding the foregoing, the GeoMet Board may, prior to the receipt of the Requisite Stockholder Vote, make a Change of Recommendation (I) if an event, fact, development or occurrence that is unknown to the GeoMet Board as of the date of this Agreement becomes known to the GeoMet Board and if the GeoMet Board determines in good faith, after consultation with outside legal counsel and financial advisors, that the failure to make a Change of Recommendation would be reasonably likely to be inconsistent with its fiduciary duties under applicable Legal Requirements or (II) in response to a Superior Proposal received by any Seller after the date of this Agreement that was not provided as a result of any violation by any Seller of its obligations under this Section 6.13 and, in response to such Superior Proposal, if the GeoMet Board determines to accept such Superior Proposal, cause this Agreement to be terminated pursuant to Section 6.4(b)(ii) and, immediately after such termination, enter into a definitive agreement with respect to such Superior Proposal, subject to satisfaction of its obligations under Section 6.4(d); provided, however, that the GeoMet Board shall not be entitled to effect a Change of Recommendation or exercise its right to terminate this Agreement pursuant to Section 6.4(b)(ii) until 11:59 p.m., Houston time, on the fourth Business Day following delivery of written notice to Buyer (“Notice Period”) from Sellers advising Buyer that the GeoMet Board intends to take such action, including, in the event that the GeoMet Board shall be effecting a Change of Recommendation or exercising its right to terminate this Agreement as a result of a Superior Proposal, a description of the material terms and conditions of any Superior Proposal and a copy of the proposed transaction agreement for any such Superior Proposal in the form to be entered into (it being understood and agreed that, in the event of an amendment to the financial terms or other material terms of such Superior Proposal, the GeoMet Board shall not be entitled to exercise such right based on such Superior Proposal, as so amended, until 11:59 p.m., Houston time, on the second Business Day following the expiration of the Notice Period with respect to such Superior Proposal as so amended). In determining whether to terminate this Agreement in response to a Superior Proposal or to make a Change of Recommendation, the GeoMet Board shall take into account any proposals made by Buyer to amend the terms of this Agreement, and Sellers shall, and shall cause their financial advisor and legal counsel to negotiate with Buyer in good faith regarding any such proposals.

29

(f) Nothing contained in this Agreement shall prohibit Sellers or the GeoMet Board from disclosing to the GeoMet Stockholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making a statement contemplated by Item 1012(a) of Regulation M-A or Rule 14d-9 promulgated under the Exchange Act, or from issuing a “stop, look and listen” statement pending disclosure of its position thereunder; provided, however, that (i) in no event shall this Section 6.13(f) (I) affect the obligations of Sellers specified in Section 6.13(a)(ii) and Section 6.13(d) or (II) permit the GeoMet Board to make a Change of Recommendation without complying with Section 6.3(e) and (ii) any such disclosure that addresses or relates to the approval, recommendation or declaration of advisability by the GeoMet Board with respect to this Agreement or an Acquisition Proposal shall be deemed to be a Change of Recommendation unless the GeoMet Board in connection with such communication publicly states that its recommendation with respect to this Agreement has not changed or refers to the prior recommendation of the GeoMet Board, without disclosing any Change of Recommendation.

6.14 GeoMet Proxy Statement; GeoMet Stockholders Meeting.

(a) As promptly as reasonably practicable following the date of this Agreement (and in no event later than twenty (20) Business Days after the date of this Agreement), the Sellers shall, with the cooperation of Buyer, prepare and file the preliminary GeoMet Proxy Statement with the SEC. Buyer shall reasonably cooperate with the Sellers in the preparation of the GeoMet Proxy Statement, including by providing the Sellers with any information regarding Buyer (or its Affiliates) that is reasonably required to be included in the GeoMet Proxy Statement. The Sellers shall use their reasonable best efforts to respond to any comments of the SEC or its staff, to clear the preliminary GeoMet Proxy Statement with the SEC as promptly as practicable after filing and to cause the GeoMet Proxy Statement to be mailed to the GeoMet Stockholders as promptly as practicable after responding to all such comments to the satisfaction of the SEC. The Sellers will advise Buyer, promptly after they receive notice thereof, of any request by the SEC or its staff for amendments or supplements to the GeoMet Proxy Statement or comments thereon and responses thereto or requests by the SEC or its staff for additional information. The Sellers will promptly provide Buyer with copies of all correspondence between the Sellers (or their Representatives) and the SEC (or its staff) regarding the GeoMet Proxy Statement or the transactions contemplated by this Agreement. No filing of, or amendment or supplement to, or correspondence to the SEC or its staff with respect to, the GeoMet Proxy Statement will be made by the Sellers, without providing Buyer and its outside legal counsel a reasonable opportunity to review and comment thereon (and the Sellers shall give reasonable consideration to all reasonable comments suggested by Buyer or its counsel). If at any time prior to the GeoMet Stockholders Meeting there shall occur any event that is required to be set forth in an amendment or supplement to the GeoMet Proxy Statement, the Sellers shall as promptly as reasonably practicable prepare and mail to the GeoMet Stockholders such an amendment or supplement.

(b) As promptly as reasonably practicable following the clearance of the GeoMet Proxy Statement by the SEC, the Sellers, acting through the GeoMet Board, shall (i) take all lawful action necessary to duly call, give notice of, convene and hold a GeoMet Stockholders Meeting for the purpose of obtaining the Requisite Stockholder Vote and not postpone or adjourn the GeoMet Stockholders Meeting except to the extent required by applicable Legal Requirements or to the extent the GeoMet Board or any committee thereof reasonably believes that such postponement or adjournment is consistent with its fiduciary duties under applicable Legal Requirements and (ii) subject to the right of the GeoMet Board to effect a Change in Recommendation pursuant to Section 6.13, use its reasonable best efforts to solicit from the GeoMet Stockholders proxies in favor of the approval of this Agreement and the transactions contemplated hereby.

7.14 Casualty Loss. If, prior to Closing, any of the Assets are materially damaged or destroyed by fire, blowout or other casualty (“Casualty Defect”), each Seller shall notify Buyer promptly after such Seller learns of such event. Sellers shall have the right, but not the obligation, to cure any such Casualty Defect by repairing such damage or, in the case of personal property or fixtures, replacing the Assets affected thereby with equivalent items, no later than the date of Closing. If the Defect Value of such affected Assets is determined to be less than 15% of the Purchase Price, Buyer shall proceed to purchase the Assets and, at the option of Buyer, either (a) the Purchase Price will be reduced by the Defect Value of the Assets attributable to the Casualty Defects and Sellers shall retain all insurance proceeds and claims against third parties in respect of any such Casualty Defect, or (b) Sellers shall assign to Buyer all of their rights to receive insurance proceeds, and all claims against third parties, in each case in respect of any such Casualty Defect, and the Purchase Price will be reduced by an amount equal to the sum of Sellers’ retention or deductible under Sellers’ insurance policies, plus the amount by which such aggregate reduction in value exceeds Sellers’ insurance policies limits.

Buyer’s offer of employment to any employee may be conditioned upon Buyer’s usual hiring procedures and standards, including but not limited to successful completion of a background check, drug test and driving record check, and also upon the occurrence of the Closing. Buyer’s offer of employment to any employee also will be conditioned upon such employee resigning their employment with Sellers and executing a resignation letter substantially in the form of Exhibit F. Sellers shall have the right to review the documents evidencing Buyer’s offers of employment described in the preceding sentence for compliance with the terms of this Agreement at least five (5) days prior to any distribution of such documents to the applicable employee. No later than five (5) days prior to the Closing Date, Buyer shall notify the Sellers as to each employee who has accepted employment with Buyer, which acceptance may be conditioned upon the occurrence of the Closing, and each employee who has rejected Buyer’s offer of employment. Buyer shall indemnify and hold harmless the Sellers and each of their officers, agents, employees and Affiliates with respect to all liabilities caused by Buyer’s conduct in regards to the employment offer process described in this Section 7.15 (including any claim of discrimination or other illegality in such selection and offer process). For the avoidance of doubt, nothing in this Section 7.15 shall affect the right of the Sellers (or any of their Affiliates) to terminate the employment of an employee for any reason or at any time.

We have had a good start to this year and we expect to pursue further opportunities to increase distributable cash flow and enhance our assets.”

ARP expects to benefit from the mature, low-decline production from the acquired assets, which will complement the company’s existing oil and gas base. Additional details on the acquired assets are as follows:

• Approximately 70 Bcfe of proved reserves in West Virginia and Virginia; 100% natural gas and proved developed

• Current net production of approximately 22 million cubic feet equivalents per day (“Mmcfe/d”) from over 400 active wells; current expected decline rate of approximately 10-12%

• Current production costs: lease operating costs of approximately $1.20/mcf; production and ad valorem taxes of approximately 10%; transportation and gathering of approximately $0.40/mcf

Wells Fargo acted as financial advisor, and Paul Hastings LLP acted as legal advisor on the transaction.

(b) EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

4.7 Counterparts; Effectiveness. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which shall constitute the same agreement. This Agreement shall become effective when each party hereto shall have received counterparts thereof signed and delivered (by telecopy or otherwise) by the other parties hereto.

4.8 Entire Agreement; Third Party Beneficiaries. This Agreement constitutes the entire agreement, and supersedes all prior agreements and understandings, both written and oral, between the parties with respect to the subject matter hereof. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person other than the parties and their respective successors and permitted assigns any right, benefit or remedy hereunder.

4.9 Severability. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect. Notwithstanding the foregoing, upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

4.10 Specific Performance. The parties hereto agree that each of Buyer and Parent would be irreparably damaged in the event that any Stockholder fails to perform any of his, her or its obligations under this Agreement. Accordingly, each of Buyer and Parent shall be entitled to an injunction or injunctions to prevent breaches of this Agreement by any Stockholder and to specific performance of the terms and provisions hereof in any court of competent jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.

4.11 Capacity as Stockholder; No Agreement as a Director or Officer. Notwithstanding anything in this Agreement to the contrary (including Section 1.6), each Stockholder signs this Agreement and makes the representations, warranties, covenants and agreements and undertakes the obligations and agreements set forth herein solely in such Stockholder’s capacity as a Stockholder of GeoMet and not in such Stockholder’s capacity (directly or through its officers, employees, agents or representatives) as a director, officer or employee of GeoMet or any of its subsidiaries or in such Stockholder’s capacity as a trustee or fiduciary of any employee benefit plan or trust. Notwithstanding anything in this Agreement to the contrary, nothing herein shall in any way restrict a director or officer of GeoMet or of any of its subsidiaries in the exercise of his or her fiduciary duties as a director or officer of GeoMet or of any of its subsidiaries or in his or her capacity as a trustee or fiduciary of any employee benefit plan or trust or prevent any director or officer of GeoMet or of any of its subsidiaries or any

trustee or fiduciary of any employee benefit plan or trust from taking or omitting to take, or be construed to create any obligation on the part of such Person to take or omit to take, any action in his or her capacity as such director, officer, trustee or fiduciary for an employee benefit plan or trust, and no such action or omission shall constitute a breach of this Agreement or otherwise result in any liability on the part of such Stockholder.

4.12 No Ownership Interest. All rights, ownership and economic benefits of and relating to the Subject Shares shall remain vested in and belong to such Stockholder, and Parent shall have no authority to exercise any power or authority to direct such Stockholder in the voting of any of the Subject Shares, except as otherwise specifically provided herein.

4.13 Interpretation. When a reference is made in this Agreement to a Section or Annex, such reference shall be to a Section of or Annex to this Agreement unless otherwise indicated. The headings contained in this Agreement or in an Annex are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Any Annex annexed hereto or referred to herein are hereby incorporated in and made a part of this Agreement as if set forth herein.

The words describing the singular number shall include the plural and vice versa and words denoting any gender shall include all genders.
