CERTAIN AMENDMENTS 
 2.1 Extension to March 31, 2012. Notwithstanding anything to the contrary in the Existing Agreement, the Commitment Period under Section 1.2 and the Maturity Date under Section 1.4
is hereby extended to March 31, 2012. Each reference to “March 31, 2011” set forth in Sections 1.2 and 1.4 of the Existing Agreement (as amended by the First and Second Amendment thereto) and in the Form of Note attached as Exhibit
A thereto is hereby replaced with “March 31, 2012.” 
 2.2 Warrant Coverage. In consideration of the
extension of the Commitment Period under Section 1.2 and the Maturity Date under Section 1.4 pursuant to Section 2.1 above, additional Warrants (together, the “2012 Extension Warrants”) to purchase an aggregate of
800,000 shares of Common Stock shall be issued to the Lenders, with each Lender entitled to receive a pro rata number of such 2012 Extension Warrants based on the portion of the Committed Funds to be loaned by each such Lender. Such 2012 Extension

 2.4 Guaranty; Reduction of Guaranty and Committed Funds. (a) The parties acknowledge that Sanderling Venture
Partners VI Co-Investment Fund, L.P. and Alafi Capital Company LLC have each entered into an Unconditional Limited Guaranty dated as of March 4, 2009 and March 3, 2009, and in each case, as affirmed by the respective guarantor in December
2009, respectively, in favor of Silicon Valley Bank, guarantying repayment of amounts set forth therein, but each having a maximum liability of $5,000,000 of principal amount under the Amended Revolver. The parties agree that the Company may agree
to extend the maturity date of the Amended Revolver to a date no later than March 31, 2012, and that in such event, the Lenders shall each cause their respective Unconditional Limited Guaranty agreements to be extended to such March 31,

March 31, 2012 in a private placement, registered direct offering, or any other offering for which the Company receives the offering proceeds, the amount of such Lender’s obligation under its Unconditional Limited Guaranty in favor of
Silicon Valley Bank shall be reduced, on a dollar-for-dollar basis, by the gross proceeds invested by such Lender, up to 100% of such Lender’s maximum liability under such Unconditional Limited Guaranty. In such event, a corresponding reduction
shall be made for such Lender in the Schedule of Committed Funds under the Agreement relating to such Lender’s obligation thereunder. The Company acknowledges that any investment by a Lender pursuant to this Section 2.4(b) may be
conditioned upon such Lender’s receipt of documentation of Silicon Valley Bank’s acknowledgement of such arrangement, in form 

  
 2 

 
satisfactory to such Lender in its sole discretion. This Section replaces and supersedes Section 2.4(b) of the Second Amendment.

statement) with respect to the maximum number of Warrant Shares issuable upon exercise of the 2012 Extension Warrants (and any other previously unregistered Warrants) on or prior to April 30, 2011, unless the Lenders agree to delay such

 2.7 CERTAIN
REPRESENTATIONS BY MANAGEMENT LLC. Trigon and CEU Eagle Ford LLC (“CEU”) have been acquiring leases in Atascosa, McMullen, Gonzales and Fayette counties in Texas in accordance with

attached hereto as Exhibit A (“Exhibit A”) and in accordance with the LADA has a right to acquire a 10% undivided interest in those leases show as “Pending” and “Possible” on Exhibit A if, as and
when such leases are acquired by CEU and Trigon. All such leases are referred to collectively as “Leases”. Management LLC further represents that CEU owns an undivided 90% interest in approximately 9,761 net mineral acres (8/8ths) and
in accordance with the LADA has a right to acquire a 90% undivided interest in those leases shown as “Pending” and “Possible” on Exhibit A if, as and when such leases are acquired by CEU and Trigon. Further Management LLC
represents that Trigon has a right to acquire no less than a 65% (of 8/8’s) interest in all such Leases acquired by Trigon and CEU on or before the Relevant Interest Notice Date (as defined in Section 3.4(c) below) provided it pays that
amount to CEU (if that is the interest acquired) in accordance with the terms of the LADA. Thereafter, subject to an election made by CEU under the LADA, Leases will be acquired by CEU in an amount equal to CEU’s AMI Interest, if at all, and

 5 

 
CEU is contractually required to assign the acquired interest in the Leases owned as of the Relevant Interest Notice Date to Trigon promptly after receipt of payment. 

ARTICLE 3 

CAPITAL AND CAPITAL ACCOUNTS 
 3.1 CAPITAL STRUCTURE. The ownership interests in the Company shall be evidenced by Membership Interests, with each Membership Interest evidencing a specific
percentage interest in the Company during its existence and in its assets upon its dissolution. 
 3.2 CAPITAL
CONTRIBUTIONS. As of the next business day following the Relevant Interest Notice Date, Management LLC (or its predecessors) shall have made cumulative Capital Contributions to the Company equal to 10% of the Funded Capital (as
defined in the LADA). Subsequent Capital Contributions shall be made as set forth below. If Management LLC has funded more than 10% of the Funded Capital as of such date, Management LLC shall be entitled to a return of such excess. 

3.3 MEMBERS. Subject to Section 15.16, the Members of the Company are GeoResources and Management LLC. Each
Member’s Membership Interest in the Company will be determined as follows: 
 (a) Management LLC’s Membership Interest
shall be a percentage interest determined by dividing (i) ten percent (10%) by (ii) the difference between one hundred percent (100%) and CEU’s AMI Interest; and 

(b) GeoResources’ Membership Interest shall be a percentage interest determined by dividing (i) the difference between ninety
percent (90%) and CEU’s AMI Interest, by (ii) the difference between one hundred percent (100%) and CEU’s AMI Interest. 
 Subject to Section 6.8(b), Persons may be admitted to the Company as Members as determined by the Managers. The terms of admission or issuance may provide for the creation of different classes or
groups of Members having different rights, powers and duties. The Managers may reflect the creation of any new class or group in an amendment to this Agreement indicating the different rights, powers and duties, and subject to such amendment being
approved by the unanimous consent of the Members. Any such admission is effective only after such new Member has executed and delivered to the Members and the Company an instrument containing the notice address of the new Member, the Member’s
ratification of this Agreement and agreement to be bound by it. 
 3.4 SUBSEQUENT CAPITAL
CONTRIBUTIONS. No Member shall be required to make any Subsequent Capital Contribution to the Company, except as may be required under the provisions of this Section 3.4, or as required by applicable law. With respect to
Subsequent Capital Contributions, the following provisions shall apply: 
 (a) LADA. The Members acknowledge that the
Company is subject to the terms of the LADA. Terms used in this Section 3.4 that are defined in the LADA shall have the meanings given in the LADA. 

  
 6 

 (b) Further Subsequent Capital Contributions. GeoResources agrees to make Subsequent
Capital Contributions to the Company in an amount sufficient to fund the reacquisition of CEU interests, the acquisition of additional leases, and fund certain drilling obligations either through Subsequent Capital Contributions or directly, both as
specified below, equal to the “Required Funder Commitment” under the LADA, but not to exceed $60,000,000, without the express approval of Geo Resources, for the purposes set forth in this Section 3.4. 

(c) Reacquisition of CEU Interests. Upon the execution of this Agreement, CEU will have the right to specify CEU’s AMI
Interest under the LADA, and upon receipt of the Relevant Interest Notice from CEU by the Company (the date of such receipt being referred to herein as the “Relevant Interest Notice Date”) will be required to pay CEU the CEU
Returned Capital. GeoResources shall contribute to the Company the funds necessary for the Company to pay the CEU Returned Capital to CEU within the time periods set forth in the LADA. The funding of these Subsequent Capital Contributions for lease
acquisitions will occur in stages with the initial funding sufficient to make the acquisition from CEU for leases shown as “Closed” on Exhibit A and for leases that are shown as “Pending” or “Possible” and that
are funded by CEU and Trigon on or before the Relevant Interest Notice Date. 
 (d) Acquisition of Additional Leases under
the LADA. Each Member of the Company will make Subsequent Capital Contributions in proportion to their respective Membership Interests as from time to time required for the Company to fund its requisite portion of the costs for the acquisition
of all subsequent leases under the LADA. 
 (e) Drilling Obligations. In addition to the foregoing capital contributions,
GeoResources will drill or cause the drilling of (i) at least 10 gross wells (the “Carry Wells”) on the acreage held by Company (such that Management LLC is carried on 1 net well (subject to reduction as set forth below) to the
tanks, with Management LLC being deemed to own for these purposes an interest in each Carry Well equal to Trigon’s working interest in each such well multiplied by Management LLC’s ownership interest in the Company), with one hundred
percent (100%) of the drilling and completion costs (related to the Company’s interest in the Carry Wells) to be funded by GeoResources, and (ii) after the Carry Wells, 10 additional gross wells (“Subsequent Wells”).
For all Subsequent Wells, the Company’s share of drilling and completion costs shall be funded by Subsequent Capital Contributions made by the Members in proportion to their Membership Interests, or at the direction of GeoResources may be
funded directly to the operator of the drilling unit, if such operator is GeoResources or an affiliate of Management LLC. Further, to the extent that a third party is the operator and the Company is a non-operating participant, GeoResources will
request the operator to recognize the interests of GeoResources and Management LLC directly for purpose of joint interest billings under the relevant joint operating account; provided, that in the event such non-operated well is a Carry Well,
GeoResources will be responsible for all of the drilling and completion costs associated with such well. The Carry Wells may be reduced by a percentage equal to one minus the Acreage Shortfall Percentage, as defined below, if the Acreage Shortfall
Percentage is less than 100%. All wells drilled by the Company, whether in operated or non-operated drilling units, will be subject to the GeoResources’ approval (based on anticipated economic results satisfactory to GeoResources) and a failure
to drill or participate shall not subject GeoResources to any penalties or damages under this Agreement or otherwise. 

  
 7 

 (f) As used herein, “Acreage Shortfall Percentage” shall mean that percentage
determined by dividing the net mineral acres (on 8/8ths basis) for the Leases that are acquired by the Company by 14,000. The Members acknowledge that the leases shown as “Possible” on Exhibit A are not subject to an existing
agreement between the landowner and the Company and in the event that the Company is not able to acquire any of the leases shown as “Possible” on Exhibit A, the Members will use their reasonable best efforts to agree on replacement
acreage that is acceptable from a land (based on the bonus payment, landowner royalty, term and lease provision) and geologic perspective to be acquired in lieu of such “Possible” leases. 

(g) To the extent that the Company has insufficient cash to fund its ongoing administrative expenses, including, without limitation,
accounting expenses under Article 13 and tax report preparation under Article 11, each Member shall make a capital contribution in proportion to its Membership Interest in such amounts as from time to time requested by the Managers for such
expenses. 
 (h) All Subsequent Capital Contributions required hereunder shall be paid to the Company within ten business days
or, in the case of payments made pursuant to the LADA, within the time specified in the LADA, following written notice from the Managers specifying in reasonable detail the expenditures to which such capital contribution relates. 

(i) In addition to the foregoing obligations of GeoResources, GeoResources shall pay to Management LLC a fee of $1,000,000 in
consideration of general and administrative expenses incurred by Management LLC prior to the date hereof; provided, however, that such fee shall be reduced in the event the Acreage Shortfall Percentage is less than 100%, in which case the total fee
due to Management LLC shall not exceed $1,000,000 times the Acreage Shortfall Percentage. The fee due to Management LLC shall be paid in increments proportional to the incremental payments by GeoResources for the leases as set forth on
Exhibit A. 
 (j) Under no circumstances shall Management LLC be required to make any Subsequent Capital
Contribution hereunder if GeoResources is not also making its prorata share of such Subsequent Capital Contribution due to the limitations set forth in Section 3.4(b). 
 3.5 FAILURE TO CONTRIBUTE. 
 (a) If a Member (the “Delinquent Member”) does not contribute by the time required all or any portion of an additional Capital Contribution that such Member is required to make under
Sections 3.4 (the “Default Amount”), then the Company, at the direction of the other members (the “Non-Defaulting Members”) holding a majority of the Membership Interests of the Non-Defaulting Members, may take any
or all of the following actions: 
 (i) pursue any remedies at law to collect the Default Amount and any interest
accrued thereon, and recover the costs of collection; or 
 (ii) require the Non-Defaulting Members to make a
Capital Contribution to the Company in an amount equal to the Default Amount, in the proportion that their Membership Interests bear to each other, which shall be treated as a recourse loan from the Non-Defaulting Members to the Delinquent Member,
secured by the Delinquent Member’s Membership Interest (the “Default

Loan”), and as a Capital Contribution of that same amount to the Company by the Delinquent Member. The principal balance of the Default Loan shall be equal to the aggregate amount of
the Capital Contribution made by the Non-Defaulting Members pursuant to this Section 3.5(a), and shall bear interest at a rate equal to the Default Interest Rate. The Non-Defaulting Members are hereby authorized to take all actions and sign all
documents they deem required or necessary to perfect their security interest in the Delinquent Member’s Membership Interest. While any Default Loan is outstanding and unrepaid, the Company shall pay directly to the Non-Defaulting Members (in
the same proportions that the Non-Defaulting Members made the Capital Contribution to the Company) any distributions to which the Delinquent Member is entitled pursuant to Article 4 until such Default Loan with interest has been repaid in full.
The principal and accrued but unpaid interest under the Default Loan shall be due and payable in full on the third anniversary of the date on which the Default Loan was made. If any Default Loan and accrued but unpaid interest thereon is not paid
when due, the Non-Defaulting Members shall, without forfeiting other remedies, be entitled to continue to receive all amounts that would otherwise be distributed by the Company to the Delinquent Member until such Default Loan with all accrued but
unpaid interest (plus any costs of collection) is paid in full. 
 (b) THE MEMBERS AGREE THAT THE LIQUIDATED DAMAGES DESCRIBED
IN THIS SECTION 3.5 ARE A FAIR AND ADEQUATE MEASURE OF THE DAMAGES THAT WILL BE SUFFERED BY THE NON-DEFAULTING MEMBERS AS A RESULT OF A BREACH BY A MEMBER OF ITS OBLIGATION TO MAKE CAPITAL CONTRIBUTIONS UNDER SECTIONS 3.4 AND NOT A PENALTY.

 3.6 NO THIRD PARTY RIGHT TO
ENFORCE. No Person other than a Member shall have the right to enforce any obligation of a Member to contribute capital hereunder and specifically no lender or other third party shall have any such rights.

 3.7 LOANS TO THE COMPANY. Any Member, directly or through
an Affiliate, may at any time or from time to time lend funds to the Company with the consent of the Managers. Any such loan shall be repayable by the Company to the Member (or its Affiliate, if applicable) at such date or dates as they may agree,
and shall bear interest and carry such other terms as they may agree at a fair market interest rate and terms for similar loans between unaffiliated parties. The Members expressly agree and acknowledge that nothing in this Section 3.8 shall be
deemed to require or otherwise obligate any Member to make any such loan to the Company. A loan by a Member to the Company shall not increase the interest of the lending Member in the capital of the Company and shall not entitle such Member to any
increased share in the Company’s capital, Profits or Losses. 
 3.8 CAPITAL ACCOUNTS.

 (a) A Capital Account shall be established for each Member and shall be determined and maintained in accordance with the
provisions of Code Section 704 and the Regulations thereunder. A Member that has more than one class or series of Membership Interests shall have a single Capital Account that reflects all such class, classes or series of

  
 9 

 
Membership Interests and regardless of time or manner in which such Membership Interests were acquired. In addition to such other adjustments as may be required under this Agreement or pursuant
to such Regulations, each Member’s Capital Account shall be (a) increased by (i) such Member’s Capital Contribution to the Company, plus (ii) the amount of any Profits and Liquidating Gains allocated to such Member and items
of Capital Account Gross Income specially allocated to such Member pursuant to Article 5, and (b) decreased by (i) the amount of any Losses and Liquidating Losses allocated to such Member and items of Capital Account Deduction
specially allocated to such Member pursuant to Article 5, (ii) the amount of any cash or other assets distributed to such Member by the Company, and (iii) the fair market value, as determined by the Managers, of any property
distributed, or deemed hereunder to be distributed, to such Member by the Company (net of any liabilities that such Member is considered to assume or take subject to under Code Section 752 upon any such distribution of property). 

(b) In accordance with Regulations Section 1.704-1(b)(2)(iv)(e), immediately prior to the actual or deemed distribution of any
Company asset in kind, the Capital Accounts of all Members and the Company’s book carrying value of such Company asset shall be adjusted upward or downward to reflect any unrealized gain or unrealized loss attributable to such Company asset as
if such unrealized gain or unrealized loss had been recognized upon an actual sale of such Company asset immediately prior to such distribution and had been allocated to the Members at such time pursuant to Article 5. For purposes of
determining such unrealized gain or unrealized loss, the fair market value, as determined by the Managers, of Company assets shall be used. 
 (c) Upon any event described in Regulation Section 1.704-1(b)(2)(iv)(f)(5), the Capital Accounts may, at the Discretion of the Managers, be restated to reflect a revaluation of the assets of the
Company in order to reflect the manner in which the unrealized income, gain, loss, or deduction inherent in such property (that has not been reflected in the Capital Accounts previously) would be allocated among the Members if there were a taxable
sale of such assets for their fair market value as determined by the Managers. 
 (d) Upon any Transfer of Membership Interests,
the Transferee shall be credited on the Company’s books with the portion of the Transferor’s Capital Account that corresponds to the Transferred Membership Interests. 

3.9 GENERAL PROVISIONS REGARDING CAPITAL
CONTRIBUTIONS. Except as otherwise expressly provided in this Agreement (a) no Member shall have the right to demand or receive a return of its Capital Contribution, (b) under circumstances requiring
hereunder a return of any Capital Contribution, no Member shall have the right to demand or receive property other than cash, and (c) no Member shall receive any interest, salary or draw with respect to its Capital Contribution or its Capital
Account. An unrepaid Capital Contribution is not a liability of the Company or of any Member. A Member shall not be required to contribute or to lend any cash or property to the Company to enable the Company to return any Member’s Capital
Contribution. 
 3.10 LIMITATION ON LIABILITY. Except as
otherwise required under the Act, the debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and no Member

  
 10 

 
shall be personally liable for or otherwise obligated with respect to any such debt, obligation or liability of the Company by reason of being a Member of the Company. The Members agree that the
rights, duties and obligations of the Members in their capacities as members of the Company are only as set forth in this Agreement and as otherwise arise under the Act. Furthermore, the Members agree that the existence of any rights of a Member, or
the exercise or forbearance from exercise of any such rights shall not create any duties or obligations of the Member in their capacities as members of the Company, nor shall such rights be construed to enlarge or otherwise alter in any manner the
duties and obligations of the Members. 
 ARTICLE 4 

DISTRIBUTION OF COMPANY FUNDS 
 4.1 DISTRIBUTIONS GENERALLY. Except as provided in Section 3.5, above, and Section 4.4, below, distributions to the Members shall be made only to all Members

rate equal to the sum of the highest marginal federal and Colorado income tax rates applicable to an individual, and (y) the amount of distributions to such Member previously made for such tax year. Distributions under this Section 4.3
shall be made equally to the Members in proportion to their Membership Interests. 
 4.4 DISTRIBUTIONS
ON DISSOLUTION AND WINDING UP. Upon the dissolution and winding up of the Company, the proceeds of liquidation after the payment of creditors as specified in

	 	(i)	40% to GeoResources; and 

  

	 	(ii)	60% to Management LLC. 

 (b) For
all wells thereafter, the CEU Spud Fee shall be distributed to the Members in proportion to their respective Membership Interests in the Company; or if the Company has been dissolved in accordance with Article 14, the in proportion to their
respective interests in the leases attributable to the well for which such spud fee was received. 
 (c) The Members agree to
use reasonable good faith efforts to negotiate compensation for the Operator of the wells drilled under the LADA, in accordance with industry practices, in the event that an affiliate of Management LLC acts as Operator, or in the event that
GeoResources or an affiliate of Management LLC is operating multiple drilling rigs on the lands covered by the LADA. In no case, shall an affiliate of Management LLC be required to serve as operator without being reasonably compensated for
out-of-pocket expenses incurred in connection with operations and for other expenses mutually determined by the parties. 
 (d)
If GeoResources or an affiliate of Management LLC serves as Operator and therefore bills and collects the CEU Spud Fee, it shall promptly upon receipt distribute such CEU Spud Fee, as specified above. 

4.6 LIMITATION ON DISTRIBUTIONS. Notwithstanding any other provision to the contrary
in this Agreement, the Company shall not make a distribution to any Member if such distribution would violate the Act or other applicable law. 
 4.7 WITHHOLDING OF TAXES. The Company will withhold taxes from distributions to the extent required to do so by applicable law. Any amounts so withheld

 INDEMNIFICATION 

9.1 LIABILITY, EXCULPATION AND INDEMNIFICATION.

 (a) To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, all Covered
Persons shall be indemnified and held harmless by the Company from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or
other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Covered Person may be involved, or is threatened to be involved, as a party or otherwise,
by reason of its status as a Covered Person; provided, that in each case the Covered Person acted in good faith and in a manner that such Covered Person reasonably believed to be in, or (in the case of a Person other than the Managers) not opposed
to, the best interests of the Company and, with respect to any criminal proceeding, had no reasonable cause to believe its conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a
plea of nolo contendere, or its equivalent, shall not create a presumption that the Covered Person acted in a manner contrary to that specified above. Any indemnification pursuant to this Section shall be made only out of the assets of the Company,
it being agreed that the Members, Managers and officers shall not be personally liable for such indemnification and shall have no 

  
 17 

 
obligation to contribute or loan any monies or property to the Company to enable it to effectuate such indemnification. 
 (b) To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by a Covered Person who is indemnified pursuant to Section 9.1(a) in defending any claim, demand,
action, suit or proceeding shall, from time to time, be advanced by the Company prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Company of any undertaking by or on behalf of the Covered Person to
repay such amount if it shall be determined that the Covered Person is not entitled to be indemnified as authorized in this Section 9.1. 
 (c) The indemnification provided by this Section 9.1 shall be in addition to any other rights to which a Covered Person may be entitled under any agreement, pursuant to any vote of the Members, as a
matter of law or otherwise, both as to actions in the Covered Person’s capacity as a Covered Person and as to actions in any other capacity, and shall continue as to a Covered Person who has ceased to serve in such capacity and shall inure to
the benefit of the heirs, successors, assigns and administrators of the Covered Person. 
 (d) The Company may purchase and
maintain insurance, on behalf of the Managers, officers and Members and such other Persons as the Managers shall determine, against any liability that may be asserted against or expense that may be incurred by such Person in connection with the
Company’s activities or such Person’s activities on behalf of the Company, regardless of whether the Company would have the power to indemnify such Person against such liability under the provisions of this Agreement. 

(e) For purposes of this Section 9.1, the Company shall be deemed to have requested a Covered Person to serve as fiduciary of an
employee benefit plan whenever the performance by it of its duties to the Company also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on a Covered Person with
respect to an employee benefit plan pursuant to applicable law shall constitute “fines” within the meaning of Section 9.1(a); and action taken or omitted by it with respect to any employee benefit plan in the performance of its duties
for a purpose reasonably believed by it to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is in, or not opposed to, the best interests of the Company. 

(f) In no event may a Covered Person subject the Members to personal liability by reason of the indemnification provisions set forth in
this Agreement. 
 (g) A Covered Person shall not be denied indemnification in whole or in part under this Section 9.1
because the Covered Person had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement. 

(h) The provisions of this Section 9.1 are for the benefit of the Covered Persons, their heirs, successors, assigns and
administrators and shall not be deemed to create any rights for the benefit of any other Persons. 

  
 18 

 (i) No amendment, modification or repeal of this Section 9.1 or any provision hereof
shall in any manner terminate, reduce or impair the right of any past, present or future Covered Person to be indemnified by the Company, nor the obligations of the Company to indemnify any such Covered Person under and in accordance with the
provisions of this Section 9.1 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal,
regardless of when such claims may arise or be asserted.

 (b) The Tax Matters Member shall take no action without the authorization of the Managers, other than such action as may be required by applicable law. Any cost or expense incurred by the Tax Matters
Member in connection with its duties, including the preparation for or pursuance of administrative or judicial proceedings, shall be paid by the Company. 
 (c) The Tax Matters Member shall not enter into any extension of the period of limitations for making assessments on behalf of the Members without first obtaining the consent of the Managers. The Tax
Matters Member shall not bind any Member to a settlement agreement without obtaining the consent of such Member. Any Member that enters into a settlement agreement with respect to any Company item (as described in Section 6231(a)(3) of

  
 20 

 
the Code) shall notify the other Members of such settlement agreement and its terms within 90 days from the date of the settlement. 

(d) No Member shall file a request pursuant to Section 6227 of the Code for an administrative adjustment of Company items for any
taxable year without first notifying the other Members. If the Managers consent to the requested adjustment, the Tax Matters Member shall file the request for the administrative adjustment on behalf of the Members. If such consent is not obtained
within 30 days from such notice, or within the period required to timely file the request for administrative adjustment, if shorter, any Member may, subject to Section 5.5 hereof, file a request for administrative adjustment on its own behalf.
Any Member intending to file a petition under Sections 6226, 6228 or other Section of the Code with respect to any item involving the Company shall notify the other Members of such intention and the nature of the contemplated proceeding. In the case
where the Tax Matters Member is intending to file such petition on behalf of the Company, such notice shall be given within a reasonable period of time to allow the Members to participate in the choosing of the forum in which such petition will be
filed. 
 (e) If any Member intends to file a notice of inconsistent treatment under Section 6222(b) of the Code, such
Member shall give reasonable notice under the circumstances to the other Members of such intent and the manner in which the Member’s intended treatment of an item is (or may be) inconsistent with the treatment of that item by the other Members.

 (f) The Members acknowledge that the tax provisions set forth in this Agreement may, from time to time, not result in the
economic consequences anticipated by the Members. Accordingly, from time to time, the Members agree that they shall approve amendments to this Agreement as are reasonably requested by a Member to reflect tax considerations consistent with the
economic provisions of this Agreement. 
 ARTICLE 12 

TRANSFER OF MEMBERS’ INTERESTS; 
 ADMISSION OF ADDITIONAL MEMBERS 
 12.1 RESTRICTIONS
ON TRANSFERS OF MEMBERSHIP INTERESTS.  
 (a) No
Member may Transfer all or any portion of its Membership Interests, to any Person other than to a Person who at the time is already a Member of the Company without obtaining the approval of a majority of the Board of Directors. 

(b) The approval by the Board of Directors of a Transfer shall also act as an approval to admit the Transferee as a Substitute Member.

 (c) It is understood that GeoResources shall have the right, without any required approval from the Board of Directors or
otherwise, to Transfer up to 50% of its Membership Interests in the Company to a third party and will promptly notify Management LLC in writing of such transaction, and the relevant terms and provisions thereof, after the completion thereof. It is
provided however, that no such Transfer may dilute the economic benefits hereunder of Management LLC. Further, to the extent that GeoResources (directly or indirectly) realizes incremental economic benefits from the Transfer in excess of the total

  
 21 

 
contributions and costs of GeoResources attributable to the Transferred Membership Interests, GeoResources shall promptly pay or assign to Management LLC one-third of such incremental economic
benefits. 
 12.2 FURTHER ADMISSIONS OF ADDITIONAL
MEMBERS. The Company may authorize the issuance of additional Membership Interests to any Person at any time for such consideration as the Company deems appropriate even if such admission causes a dilution of the amount of
Membership Interests then owned by Members of the Company. The issuance of additional Membership Interests to any Person who is not then a Member shall be subject to the approval provisions of Section 6.8. 

12.3 TAG ALONG. If GeoResources, proposes to Transfer, directly or indirectly, other
than a Transfer to a Person who is then a Member of the Company, or as otherwise permitted under Section 12.1(c), its Membership Interests, or if the leases held by the Company have been distributed to the Members as provided in Article 14,
such that after such Transfer GeoResources will have transferred in the aggregate more than 50% of its Membership Interests or leasehold interests, then GeoResources shall give written notice (the “Sale Notice”) to Management LLC at
least 30 calendar days prior to the closing of such Transfer. The Sale Notice shall describe in reasonable detail the proposed Transfer including, without limitation, the amount of interests to be transferred, the nature of such Transfer, the
consideration to be paid, whether such consideration is to be paid in one lump sum or installments, the name and address of each prospective transferee, and the other material terms of the Transfer (the “Sale Terms”). Upon such Sale
Notice: 
 (a) The consummation of such Transfer shall be subject to the right (the “Co-Sale Right”) of
Management LLC to, upon written notice to GeoResources within 10 calendar days after receipt of the Sale Notice, participate in such Transfer by transferring a percentage of its Membership Interests or leasehold interests, as applicable, equal to
the percentage being Transferred by GeoResources on the same terms and conditions specified in the Sale Notice. 
 12.4
GEORESOURCES RIGHT OF FIRST OFFER. 
 (a) If at any time or times Management LLC proposes to Transfer, directly or indirectly, other than a Transfer to a Person who is then a Member of the Company, its Membership Interests, or if the leases
held by the Company have been distributed to the Members as provided in Article 14, then Management LLC shall deliver written notice (the “ROFO Notice”) to GeoResources of such intent to sell specifically identifying the
Membership Interest or leases to be sold (the “Subject Properties”). 
 (b) For thirty (30) days following
the receipt of the ROFO Offer by GeoResources, GeoResources shall have the right, at its option, to negotiate with Management LLC regarding the purchase of the Subject Properties and to submit an offer to purchase all (but not less than all) of the
Subject Properties, which option may be exercised by delivering a written binding purchase offer (the “Purchase Offer”) to Management LLC within such 30-day period. 

(c) To the extent that Management LLC does not elect to sell to GeoResources pursuant to the Purchase Offer, Management LLC shall be free
to pursue a transaction and to 

  
 22 

 
enter into a purchase and sale agreement (“PSA”) with a third party during the one hundred fifty (150) days after receipt of the Offer Period. Any sale by Management LLC to
a third party in accordance with the terms hereof shall be at a price and on terms no more favorable to the purchaser than those specified in the Purchase Offer (if GeoResources submitted a Purchase Offer for the Subject Properties), or Management
LLC shall be required to again offer the Subject Properties to GeoResources on the terms specified in the PSA and GeoResources shall have fifteen days in which to elect to purchase on such terms by executing an agreement substantially similar to the
PSA within such 15-day period. 
 (d) The rights of GeoResources under this Section 12.4 shall terminate on the earlier of
(i) a change in control of GeoResources, (ii) December 31, 2013, or (iii) the failure of GeoResources to complete any purchase pursuant to a Purchase Offer. 
 ARTICLE 13 
 BOOKS OF ACCOUNT, RECORDS AND REPORTS 

13.1 PREPARATION AND MAINTENANCE OF BOOKS

the Company determines is permissible and would be in the best interests of the Company.

activities necessary for the preparation of each Members’ federal and state income tax returns, and upon the written request of a Member, the Company shall send or cause to be sent such information relevant for such Member to each requesting
Member within 90 days after the end of each taxable year, unless the Company reasonably determines there is good reason to defer the sending of such information, but in no event shall such information be sent to such Member later than 180 days
after the end of the taxable year. If the Company deems it required or desirable, a copy of the Company’s federal, state and/or local income tax or information returns for that year shall also be sent to such Member along with such information.

 24 

 (b) At any time, on or before June 30, 2011, Management LLC will have the right to

Company’s total costs incurred in acquiring those leasehold interests. 
 (c) Except as otherwise provided herein, no
Member may compel a distribution in kind by the Company or may be compelled to accept a distribution of any asset in kind from the Company unless such Member is receiving an undivided interest in such asset equal to its Membership Interest. Subject
to the foregoing, the Board of Directors may cause the Company to distribute assets in kind to the Members from time to time. 

14.2 DISSOLUTION. The death, dissolution, bankruptcy, expulsion or removal of a Member shall not cause the
dissolution of the Company, and upon any such event the business of the Company shall continue to be conducted pursuant to the terms of this Agreement. The Company shall be dissolved and its affairs wound up on the happening of any of the following
events (herein each a “Dissolution Event”):

Membership Interests shall continue to share distributions, profits, losses and allocations during the period of liquidation in accordance with Articles 3, 4 and 5.

 EXHIBIT B 
 ADDITIONAL ALLOCATIONS 
 The following Items
are hereby incorporated into the Agreement: 
 1. Solely for purposes of determining a Member’s Capital Account in applying
the provisions of Items 1 through 7 of this Exhibit B, the anticipated adjustments, allocations and distributions described in Regulations Section 1.704-l(b)(2)(ii)(d)(4)-(6) shall be taken into account, and each Member shall be
deemed obligated to restore any deficit in its Capital Account to the extent of the sum of its share of the “Minimum Gain”, as determined pursuant to Regulations Section 1.704-2(g)(1), and its share of the “Partner
Nonrecourse Debt Minimum Gain”, as determined pursuant to Regulations Section 1.704-2(i)(5). 
 2. Notwithstanding
any other provision of this Exhibit B or of Section 3.4 or Article 5, no allocation of Loss or Liquidating Loss (or items thereof) shall be made to any Member if such allocation would result in such Member having a negative balance
in its Capital Account at the close of such year in excess of the amount it would be required to restore, or is deemed to be obligated to restore on a liquidation of the Company at the close of such year. Any Loss or Liquidating Loss (or items
thereof) that cannot be allocated to a Member pursuant to the restrictions contained in this Item 2 of Exhibit B shall be allocated to the other Members of the Company (to the extent not inconsistent with the restrictions of this
Item 2 of Exhibit B) in accordance with the ratio of their then respective Capital Account balances. 
 3.
Notwithstanding any other provision of this Exhibit B or of Section 3.4 or Article 5, in the event any Member unexpectedly receives an adjustment, allocation or distribution described in clause (4), (5) or (6) of
Regulations Section 1.704-1(b)(2)(ii)(d) that results in such Member having a negative balance in its Capital Account at the close of such year in excess of the amount that it is obligated to restore or deemed obligated to restore on a
liquidation of the Company at the close of such year, or for any other reason has a deficit Capital Account balance in excess of such amount, such Member shall be allocated Profit or Liquidating Gain (or items thereof), prior to the allocations
pursuant to Sections 3.4, 5.1 or 5.2, in an amount and manner sufficient to eliminate such excess as promptly as possible. 

4. In accordance with and pursuant to Regulations Section 1.704-2(i)(1), all “Partner Nonrecourse Deductions”, as
defined in that Regulation, shall be allocated to the Member that bears the economic risk of loss on the “Partner Nonrecourse Debt”, as defined in Regulation Section 1.704-2(b)(4), giving rise to such deductions as determined
under that Regulation. 
 5. In accordance with and pursuant to Regulation Sections 1.704-2(f) and 1.704-2(i)(4) (and
subject to the exceptions set forth therein), if there is a net decrease in either Minimum Gain or Partner Nonrecourse Debt Minimum Gain or both during any taxable year, all Members shall be allocated, before any other allocation is made of Profit
or Liquidating Gain (and other income and gain) and Loss or Liquidating Loss (or other loss or deduction) for such taxable year, items of Profit and Liquidating Gain for such year (and, if necessary, subsequent years) in an amount equal to the
Member’s share in the decrease in Minimum Gain or Partner 

 
Nonrecourse Debt Minimum Gain, as determined pursuant to Regulation Sections l.704-2(g)(2) and 1.704-2(i)(4). 
 6. To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Regulation Sections 1.704-1(b)(2)(iv)(m)(2) or
1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts, the amount of such adjustment to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment
decreases such basis), and such gain or loss shall be specially allocated to the Member or Members to whom such adjustment relates as determined in accordance with such Regulations. 
 7. It is the intent of the parties to this Agreement that allocation required by Items 1 through 5 of this Exhibit B (the “Regulatory Allocations”) satisfy the requirements of
certain Regulations under Section 704(b) of the Code. It is further intended that the allocations under this Exhibit B and under Section 3.4 and Article 5 shall effect an allocation for Federal income tax purposes in a manner
consistent with Section 704(b) of the Code and comply with any limitations or restrictions therein and, to the extent possible, that any allocations pursuant to Items 1 through 5 of Exhibit B shall be offset with other special
allocations of Profits, Losses, Liquidating Gains and Liquidating Losses (or items thereof) in whatever manner the Managers reasonably and in good faith determine so that, after such offsetting allocations are made, each Member’s Capital
Account balance is (to the extent possible) equal to the Capital Account balance such Member would have had if the Regulatory Allocations were not part of this Agreement and all items of income, gain, loss and deduction were allocated pursuant to
Sections 3.4, 5.1 and 5.2. In exercising its Discretion under this Item 7 of Exhibit B, the Managers shall take into account future Regulatory Allocations that, although not yet made, are likely to offset other Regulatory
Allocations previously made. If for any reason the allocations contained in this Agreement conflict with the Regulations promulgated under Section 704 of the Code, the Members acknowledge that such Regulations shall control. 

8. For federal income tax purposes, except as otherwise provided in Items 8, 9 or 10 of this Exhibit B, items of income, gain,
loss and deduction shall be allocated in accordance with the allocation of the corresponding item of Profits, Losses, Liquidating Gains and Liquidating Losses for purposes of maintaining Capital Accounts. 

9. For tax purposes, recapture of tax deductions arising out of a disposition of property shall, to the extent consistent with the
allocations for tax purposes of the gain or amount realized giving rise to such recapture, be allocated to the Members in the same proportions as the recaptured deduction was originally allocated. 

10. For tax purposes, income, gain, loss, and deduction with respect to property reflected in the Capital Accounts at a book value other
than its adjusted basis shall be shared among the Members so as to take account of the variation between the basis of the property to the Company and its fair market value at the time of the contribution. The preceding sentence shall be administered
in any manner determined by the Managers that is consistent with Treasury Regulations under Code Sections 704(c) and 704(b).
