the business of the Partnership may be conducted under such other name or names (including the name of the Managing Partner) as the Managing Partner shall determine to be necessary or desirable. The Managing Partner shall cause to be filed on behalf
of the Partnership such partnership or assumed or fictitious name certificate or certificates or similar instruments as may from time to time be required by law. 
 Section 1.3 Business. The business of the Partnership shall be the following: (a) to become a party to the Program Agreement; (b) to acquire Leases from MOC and its Affiliates and
from third parties in accordance with the terms of the Program Agreement; (c) to explore, drill, develop, operate, and dispose of such Leases; (d) to produce, collect, store, treat, deliver, market, sell, or otherwise dispose of oil, gas,
and related minerals from such Leases; and (e) to take all such actions which may be incidental thereto as the Managing Partner may determine. The Partnership may also purchase or acquire equipment, processing facilities, and other property
associated with such Leases and acquire interests in and invest in joint ventures and other partnerships (including affiliated joint ventures or affiliated partnerships) or other entities (including corporations) that hold or are formed to acquire
Leases in Prospects if, in the judgment of the Managing Partner, such acquisitions or investments are necessary or desirable to the acquisition by the Partnership of Leases in Prospects or the drilling and completion of wells thereon. In addition,
the Partnership may participate in any other type of transaction relating to Leases or Prospects or the drilling and completion of wells thereon if the economic effect of such transactions is the same as the ownership of such Leases or Prospects by
the Partnership. 

  
 1 

 Section 1.4 Principal Office. The location of the principal place of business of
the Partnership shall be 3901 South Broadway, Tyler, Texas 75701. The Managing Partner, at any time and from time to time, may change the location of the Partnership’s principal place of business and may establish such additional place or
places of business of the Partnership as the Managing Partner shall determine to be necessary or desirable, provided notice thereof is given to the Investor Partners within 30 days of such change or establishment. The registered office of the
Partnership in the State of Delaware shall be at Corporation Trust Center, 1209 Orange Street, Wilmington, County of Newcastle, Delaware 19801, and its registered agent for service of process on the Partnership at such registered office shall be
Corporation Trust Corporation. 
 Section 1.5 Names and Addresses of Partners. MD is the sole Managing Partner of
the Partnership and its address is 3901 South Broadway, Tyler, Texas 75701. The Organizational Partner’s name is Curtis W. Mewbourne and his address is 3901 South Broadway, Tyler, Texas 75701. The name and business, residence, or mailing
address of each Investor Partner will be maintained in the Partnership records. The date upon which each such person became an Investor Partner shall be the date set forth in Partnership records. The address of each Investor Partner for the purpose
of receiving notices and all other communications hereunder shall be the address shown in the Subscription Agreement executed by such Investor Partner or such other address as may be supplied by such Investor Partner to the Managing Partner in the
manner specified in Section 11.1. 
 Section 1.6 Term. The Partnership shall commence upon the completion of
filing for record of an initial Certificate of Limited Partnership for the Partnership in accordance with the Delaware Act and shall continue until terminated in accordance with Article IX.

Section 1.7 Filings. Upon the request of the Managing Partner, the parties hereto shall immediately execute and deliver all
such certificates and other instruments conforming hereto as shall be necessary for the Managing Partner to accomplish all filing, recording, publishing, and other acts appropriate to comply with all requirements for the formation and operation of a
limited partnership under the laws of the State of Delaware and for the formation, qualification, and operation of a limited partnership (or a partnership in which the Investor Partners have limited liability) in all other jurisdictions where the
Partnership shall propose to conduct business. 
 Section 1.8 Title to Partnership Property. All property owned by
the Partnership, whether real or personal, tangible or intangible, shall be deemed to be owned by the Partnership as an entity, and no Partner, individually, shall have any ownership of such property. The Partnership shall hold its assets in its own
name, except that its interests in Leases may be held in the name of the Program Manager as contemplated by the Program Agreement. 

  
 2 

 Section 1.9 Conversion of General Partner Interests into Limited Partner
Interests. As soon as practicable after the completion of the Partnership’s drilling activities, the Interests held by the General Partners will be converted to Limited Partner Interests. In order to accomplish such conversion, the Managing
Partner will (a) file an amended certificate of limited partnership with the Secretary of State of the State of Delaware removing the General Partners as general partners of the Partnership and (b) take such other actions as are necessary
or appropriate to accomplish conversion of the General Partner Interests held by the General Partners to Limited Partner Interests. Notwithstanding the foregoing, the Managing Partner shall not be obligated to cause the conversion of the General
Partner Interests held by the General Partners to Limited Partner Interests, or may delay such conversion, if the Managing Partner determines that such conversion at that time would not be in the best interests of the Investor Partners or the
Partnership; provided that if the Managing Partner determines that such conversion would not be in the best interests of the Investor Partners or the Partnership, the insurance coverage limits, including umbrella policy limits, will not be reduced
unless such coverage becomes unobtainable or is only available at premiums which are prohibitively more expensive than the premiums now being paid for such policies. If conversion is so delayed, the Managing Partner will continue to have the power
and authority to cause such conversion at any time during the term of the Partnership if the Managing Partner determines that conversion is in the best interests of the General Partners and the Partnership. Upon filing the amended certificate of
limited partnership reflecting the conversion of the General Partner Interests held by General Partners to Limited Partner Interests, the conversion will be effective and thereafter each General Partner will have the rights and obligations of a
Limited Partner and will be entitled to limited liability to the extent provided by the Delaware Act; provided that those General Partners will remain liable to the Partnership for their proportionate shares of Partnership obligations and
liabilities arising prior to the conversion of their General Partner Interests to Limited Partner Interests.

 “Program Well” shall mean any oil and gas well in which the Participants
have an interest pursuant to the Program Agreement. 
 “Prospect” shall mean an area covering lands which, in the
opinion of the Program Manager, contains subsurface structural or stratigraphic conditions making it susceptible to the accumulation of oil or gas in commercially productive quantities at one or more Horizons. The area, which may be different for
different Horizons, shall be designated by the Program Manager and shall be enlarged or contracted from time to time on the basis of subsequently acquired information to define the anticipated limits of the associated oil and gas reserves and to
include all acreage encompassed therein. A “Prospect” with respect to a particular Horizon may be limited to the minimum area permitted by state law or local practice, whichever is applicable, to protect against drainage from adjacent
wells if the well to be drilled by the Partnership is to a Horizon containing Proved Reserves. 
 “Proved Reserves”
shall mean those quantities of crude oil, natural gas, and natural gas liquids which, upon analysis of geological and engineering data, appear with reasonable certainty to be recoverable in future years from known oil and gas reservoirs under
existing economic and operating conditions. Proved Reserves are limited to those quantities of oil and gas which can be expected, with little doubt, to be recoverable commercially at current prices and costs, under existing regulatory practices and
with existing conventional equipment and operating methods. Depending upon their status or development, Proved Reserves will be subdivided into the following classifications and have the following definitions. 

(a) “Proved Developed Reserves” shall mean Proved Reserves which can be expected to be recovered through existing wells with
existing equipment and operating methods. This classification shall include: 
 (i) “Proved Developed Producing
Reserves,” which are Proved Developed Reserves which are expected to be produced from existing completion intervals now open for production in existing wells; and 
 (ii) “Proved Developed Non-Producing Reserves,” which are Proved Developed Reserves which exist behind the casing of existing wells, or at minor depths below the present bottom of such wells,
which are expected to be produced through these wells in the predictable future, where the cost of making oil and gas available for production is relatively small compared to the cost of a new well. 

  
 8 

 Additional oil and gas expected to be obtained through the application of improved recovery
techniques are included as Proved Developed Reserves only after testing by a pilot project or after the operation of an installed program has confirmed through production that increased recovery will be achieved. 

(b) “Proved Undeveloped Reserves” shall mean all reserves which are expected to be recovered from additional wells on undrilled
acreage or from existing wells where a relatively major expenditure is required for recompletion. Such reserves on undrilled acreage are limited to those drilling units offsetting productive units which are reasonably certain of production when
drilled. Proved Reserves for other undrilled units are claimed only where it can be demonstrated with certainty, based on accepted geological, geophysical, and engineering studies and data, that there is continuity of reservoir from an existing
productive formation. No estimates for Proved Undeveloped Reserves are attributable to any improved recovery technique contemplated for any acreage, unless the techniques to be employed have been proved effective by actual tests in the same areas
and reservoir. 
 “Reconstituted Partnership” shall mean the Partnership, as reconstituted by a Majority in Interest
of the Investor Partners pursuant to Section 9.3. 
 “Reporting and Legal Expenses” shall mean all third party
accounting fees, costs, and expenses associated with obtaining audits of books and records, third party engineering fees, costs, and expenses associated with annual reserve reports, the cost of disseminating information to Investor Partners, and
third party attorney’s fees and other legal fees, costs, and expenses associated with matters that are attributable to the Drilling Program’s or the Partnership’s business. 

“Right of Presentment” shall mean the right of Investor Partners to request the Managing Partner to purchase for cash all of
that Investor Partner’s Interests, subject to certain conditions. 
 “Roll-Up” shall mean a transaction involving
the acquisition, merger, conversion, or consolidation, either directly or indirectly, of the Partnership and the issuance of securities of a Roll-Up Entity. Such term does not include a transaction involving securities of any Partnership that have
been listed for at least 12 months on a national exchange or traded through the National Association of Securities Dealers Automated Quotation National Market System or a transaction involving the conversion to corporate, trust, or association form

 CAPITALIZATION 

Section 3.1 Capital Contributions of Investor Partners. Each subscriber shall be accepted as an Investor Partner only after
(a) such subscriber has deposited or has had deposited on its behalf in a segregated escrow account at Southside Bank, Tyler, or another federally insured institution designated by MD, the full amount of the Capital Contribution of such
subscriber in cash and (b) the Managing Partner has approved and accepted the Subscription Agreement executed by such subscriber. By executing and delivering the Subscription Agreement, upon its acceptance, each Investor Partner shall be
irrevocably committed to contribute to the capital of the Partnership the amount stated in such Investor Partner’s Subscription Agreement as the Capital Contribution of such Investor Partner. If the sum of Subscription Agreements committed and
accepted at or prior to the end of the subscription period is at least $15,000,000, the Managing Partner may cause all subscribers who have been approved by the Managing Partner to be admitted to the Partnership as Limited Partners or General
Partners, and the Capital Contributions shall be paid to the Partnership. If less than $15,000,000 of Subscription Agreements shall have been committed by the Investor Partners and accepted at the end of the subscription period, the amount of the
subscriptions paid by each subscriber shall be returned with any interest earned thereon. 
 Section 3.2 Contributions
of Managing Partner. The Managing Partner shall not be required to make any contribution to the capital of the Partnership. Although the Managing Partner is personally liable under applicable laws for the debts and obligations of the
Partnership, all such debts and obligations shall be paid or discharged first with Partnership assets (including insurance proceeds) before the Managing Partner shall be obligated to pay or discharge any such debt or obligation with its personal
assets. 
 Section 3.3 Return of Contributions. Except as otherwise provided in this Agreement, no interest shall
accrue on any Capital Contributions to the Partnership. No Partner shall have the right to withdraw or to be repaid any capital contributed by such Partner except as otherwise specifically provided in this Agreement or required by law.

to the Partnership other than as provided in Section 3.1 hereof or (b) to lend any funds to the Partnership. The Interests are nonassessable; however, General Partners are liable, in addition to their Capital Contributions, for Partnership
obligations and liabilities represented by their ownership of interests as general partners, in accordance with the Delaware Act.

 ARTICLE IV 
 ALLOCATIONS AND DISTRIBUTIONS 
 Section 4.1 Allocation Among
Partners. Except as provided in Section 4.2 below, each Partner shall share Partnership items of costs, expenditures, deductions (other than depletion), credits, income, revenues, gain, loss, and distributions allocated, charged, or
credited to the Partners hereunder in accordance with the proportion that the Sharing Ratio of such Investor Partner bears to the aggregate Sharing Ratios of all Partners. 
 Section 4.2 Allocations. 
 (a) Except as provided in subsections
(b) through (f) below, all costs and revenues (including without limitation, revenues derived by the Partnership from, and distributed to the Partnership by, the Drilling Program) of the Partnership and all items of income, gain, amount
realized, loss, deduction, recapture, and credit for purposes of any applicable federal, state, or local income tax law, rule, or regulation shall be allocated to the Partners in accordance with their respective Sharing Ratio. 

(b) All costs incurred by the Partnership in connection with the performance of any special services requested by a Partner and any tax
deductions relating thereto shall be allocated 100% to the Partner requesting such services. 
 (c) All interest income directly
or indirectly resulting from the investment of the Investor Partners’ Capital Contributions following the payment thereof to the Partnership shall be allocated 100% to the Investor Partners, and shall be allocated among such Investor Partners
proportionately based on each Investor Partner’s respective cash contributions actually paid to the Partnership. 
 (d)
Cost and percentage depletion deductions and the gain or loss on the sale or other disposition of property the production from which is or would be (in the case of nonproducing properties) subject to depletion (herein sometimes called
“depletable property”) shall be computed separately by the Partners rather than the Partnership. For purposes of making such computations the Partnership’s adjusted basis in each depletable property shall be allocated under
Section 613A(c)(7)(D) of the Code to the Partners in accordance with their respective Sharing Ratio. The amount realized on the sale or other disposition of each such property shall be allocated to the Partners in proportion to each
Partner’s respective share of the revenues from the sale or other disposition of such property provided for in Section 4.2(a). For purposes of allocating amounts realized upon any such sale or disposition which are deemed to be received
for federal income tax purposes and which are attributable to Partnership indebtedness or indebtedness to which the depletable property is subject at the time of such sale or disposition, such amounts shall be allocated in the same manner as
Partnership revenues used for the repayment of such indebtedness would have been allocated under Section 4.2(f). 

  
 12 

 (e) Notwithstanding any other provision of this Section 4.2 to the contrary, if during
any taxable year of the Partnership the allocation of any loss or deduction (net of any income or gain) to any Partner (the “Deficit Partner”) would cause or increase a deficit balance in the Deficit Partner’s Adjusted Capital Account
as of the end of such taxable year, only the amount of such loss or deduction that reduces the balance to zero shall be allocated to the Deficit Partner and the remaining loss or deduction shall be allocated to the Partners whose Adjusted Capital
Accounts have positive balances remaining at such time in proportion to such positive balances. After any such allocation, any Partnership income or gain (or amount realized in excess of Simulated Basis) that would otherwise be allocated to the
Deficit Partner for any fiscal year under this Section 4.2 which is in excess of the cash distributions to the Deficit Partner for such fiscal year shall be allocated instead to the Partners to whom the Deficit Partner’s share of losses
and deductions were allocated under the preceding sentence until the amount of such income or gain (or amount realized) so allocated equals the amount of loss or deduction previously so allocated to such other Partner. 

(f) Notwithstanding the foregoing provisions of this Section 4.2, prior to making any other allocation under this Section 4.2,
the Partnership shall allocate the following items of income to the Partners: 
 (i) Pursuant to section 1.704-2(f) of the
Treasury Regulations (relating to minimum gain chargebacks), if there is a net decrease in Minimum Gain for such year (or if there was a net decrease in Minimum Gain for a prior fiscal year and the Partnership did not have sufficient amounts of
profit during prior years to allocate among the Partners under this Section 4.2(f)(1), then items of Partnership income or revenue shall be allocated, before any other allocation is made pursuant to the preceding provisions of this
Section 4.2 for such year, to each Partner in an amount equal to such Partner’s share of the net decrease in such minimum gain (as determined under section 1.704-2(g)(2) of the Treasury Regulations). 

(ii) Pursuant to section 1.704-1(b)(2)(ii)(d) of the Treasury Regulations (relating to “qualified income offsets”), items of
Partnership income or revenue shall be allocated, before any other allocation is made pursuant to the preceding provisions of this Section 4.2 for such year, among the Partners with deficit balances in their Adjusted Capital Accounts (as
determined, after giving effect to all adjustments attributable to the allocations provided for in Section 4.2(f)(1) hereof and as increased by any amounts which such Partner is deemed obligated to restore under sections 1.704-1 and 1.704-2 of
the Treasury Regulations but before giving effect to any adjustment attributable to other allocations provided for in succeeding provisions of this Section 4.2) in amounts and the manner sufficient to eliminate such deficit balances as quickly
as possible. 
 Section 4.3 Distributions. 
 (a) All interest earned by the Partnership as the result of the investment of the Partners’ Capital Contributions following the payment thereof to the Partnership shall be distributed periodically to
the Partners at such time or times as the Managing Partner shall in its discretion determine. 

  
 13 

 (b) At least quarterly, all cash funds of the Partnership (other than interest as described
in Section 4.3(a) above, borrowed funds, if any, and Capital Contributions) which the Managing Partner reasonably determines are not needed for the payment of existing or anticipated Partnership obligations and expenditures shall be distributed
to the Partners. All cash funds of the Partnership to be distributed to the Partners shall be distributed to the Partners in the same respective percentages as the revenues from which such cash funds are derived are allocated to such Partners
pursuant to Section 4.2 (after deducting therefrom the costs charged to such Partners pursuant to Section 4.2). In addition to restrictions set forth in Section 5.2(a), in no event, shall funds be advanced or borrowed for purposes of
distributions, if the amount of such distributions would exceed the Partnership’s accrued and received revenues for the previous four quarters, less paid and accrued operating costs with respect to such revenues. The determinations of such
revenues and costs shall be made in accordance with generally accepted accounting principles consistently applied. Cash distributions from the Partnership to the Managing Partner shall only be made in conjunction with distributions to Investor
Partners and only out of funds properly allocated to the Managing Partner’s account. 
 (c) Any distribution in liquidation
of a Partner’s interest in the Partnership other than pursuant to Section 8.3, Section 8.6, Section 9.3, or Section 9.4 shall be in an amount of cash or fair market value of property equal to the positive capital account
balance of such Partner at the time his interest is liquidated, after such capital account balance has been adjusted in accordance with Section 7.1(c) and the applicable Treasury Regulations under Section 704(b) of the Internal Revenue
Code and shall be made by the later of (i) the end of the Partnership taxable year in which such liquidation occurs or (ii) 90 days after the date of such liquidation. No Partner with a deficit balance in his or its capital account after a
distribution in liquidation of such Partner’s interest in the Partnership shall be liable to the Partnership for such deficit balance. 
 (d) In the event an amount of Partnership funds equal to the total Capital Contributions of the Partners has not been expended or committed for expenditure within 12 months after the admission of the
Investor Partners to the Partnership, the Managing Partner shall distribute, as a return of capital, to the Partners, proportionately in accordance with their respective Sharing Ratios as of the date of the Investor Partners’ admission to the
Partnership, the amount of such unexpended and uncommitted Partnership funds (together with a proportionate amount of the Management Fees), after deducting therefrom an amount that the Managing Partner reasonably determines will be equal to the
operating capital to be required by the Partnership that will not be provided by anticipated revenues from Partnership operations. 
 Section 4.4 Allocations on Transfers. In the event of an assignment of a Partner’s interest in the Partnership pursuant to Article VIII, deductions, credits, and income of the Partnership
for federal, state, and local income tax purposes shall, unless otherwise required by applicable Treasury Regulations, be allocated between the assignor and assignee based on the number of days of the year during which each party owned such
interest.

expenditure; 
 (b) Without having first received the prior consent of a Super Majority in Interest of the Investor Partners,
cause the Partnership to participate in a proposed Roll-Up transaction; provided, however, the participation of the Partnership in a proposed Roll-Up transaction shall be subject to the restrictions set forth in Section 5.10(j); 

(c) Except for a sale of all or substantially all of the assets of the Partnership by the Managing Partner acting in its capacity as

Section 5.3 Services of Managing Partner. During the existence of the Partnership, the Managing Partner shall devote such
time and effort to the Partnership business as may be necessary to promote adequately the interests of the Partnership and the mutual interests of the Partners; however, it is specifically understood and agreed that the Managing Partner shall not be
required to devote full time to Partnership business, and the Managing Partner and its Affiliates may at any time and from time to time engage in and possess interests in other business ventures of any and every type and description, independently
or with others, including without limitation, the acquisition, ownership, exploration, development, operation, and management of oil and gas properties for themselves and other persons and the organization and management of other partnerships and
joint ventures similar to the Partnership, and neither the Partnership nor any Investor Partner shall by virtue of this Agreement or the law of partnership opportunity have any right, title, or interest in or to such independent ventures. It is
specifically recognized that the Managing Partner and its Affiliates are currently engaged in the exploration for and production of oil and gas both for their account and for others, and nothing herein contained shall be deemed to prevent any of
them from continuing such activities, individually, jointly with others, or as a part of any other partnership or joint venture to which any of them is or may become a party, in any locale, and in fields or areas of operation in which the
Partnership may likewise be active, or from dealing with the Partnership as an independent party, nor as requiring any of them to permit the Partnership to participate in any such operations in which any of them may be interested and each Investor
Partner hereby waives, relinquishes, and renounces any such right or claim of participation. However, except as otherwise provided herein, the Managing Partner and any of its Affiliates may pursue business opportunities that are consistent with the
Partnership’s investment objectives for their own account only after they have determined that such opportunity either cannot be pursued by the Partnership because of insufficient funds or because it is not appropriate for the Partnership under
the existing circumstances. 

  
 19 

 Section 5.4 Liability of Managing Partner and Its Affiliates. Neither the
Managing Partner nor any of its Affiliates shall have any liability to the Partnership or to any Partner for any loss suffered by the Partnership which arises out of any action or inaction performed or omitted by the Managing Partner or such
Affiliate, if the Managing Partner in good faith has determined, as of the time of the conduct or omission, that the course of conduct or omission was in the best interests of the Partnership, the Managing Partner or such Affiliate was acting on
behalf of or performing services for the Partnership, and that such conduct or omission did not constitute negligence or misconduct. 
 Section 5.5 Indemnification of Managing Partner and Its Affiliates. 

(a) The Partnership shall indemnify the Managing Partner and its Affiliates against any losses, judgments, liabilities, expenses, and
settlements sustained or incurred by the Managing Partner or such Affiliate as a result of any threatened, pending, or completed claim, action, suit, or proceeding, whether civil, criminal, administrative, arbitrative, or investigative, any appeal
in such a claim, action, suit, or proceeding, and any inquiry or investigation that could lead to such a claim, action, suit, or proceeding and which in any such case relates or which otherwise arises from or is attributable to any acts, omissions,
or operations performed or omitted by the Managing Partner or its Affiliates acting on behalf of or performing services for the Partnership that are within the scope of its authority as set forth in this Agreement or the Program Agreement or which
otherwise relates to the activities and business affairs of the Partnership; provided that the Managing Partner has determined in good faith, as of the time of the conduct or omission, that the conduct or omission was in the best interests of the
Partnership and that the conduct or omission did not constitute negligence or misconduct. 
 (b) Notwithstanding anything to the
contrary contained in Sections 5.4 and 5.5(a), neither the Managing Partner, its Affiliates, nor any person acting as a broker-dealer shall be indemnified by the Partnership for any losses, liabilities, or expenses arising from or out of an alleged
violation of federal or state securities laws unless (i) there has been a successful adjudication on the merits of each count involving alleged securities laws violations as to the particular indemnitee and the court approves indemnification of
the litigation costs, (ii) such claims have been dismissed with prejudice on the merits by a court of competent jurisdiction as to the particular indemnitee and the court approves indemnification of the litigation costs, or (iii) a court
of competent jurisdiction approves a settlement of the claims against a particular indemnitee and finds that indemnification of the settlement and related costs should be made, and the court considering the request for indemnification has been
advised of the position of the Securities and Exchange Commission, and all state securities regulatory authorities in which Interests in the Partnership were offered or sold as to indemnification for violations of securities laws. 

  
 20 

 (c) The Partnership may purchase and maintain insurance on behalf of the Managing Partner
and its Affiliates against any liabilities asserted against or expenses incurred by the Managing Partner and its Affiliates in connection with Partnership or Drilling Program activities, provided that the Partnership shall not incur the cost of that
portion of any insurance, which insures the Managing Partner or its Affiliates against any liability with respect to which the Managing Partner and its Affiliates are denied indemnification under the provisions of Sections 5.4 and 5.5; provided,
however, that nothing contained herein shall preclude the Partnership from purchasing and paying for such types of insurance including extended coverage liability and casualty and workers’ compensation, as would be customary for any person
owning comparable assets and engaged in a similar business, or from naming the Managing Partner and its Affiliates as additional insured parties thereunder, provided, that the naming of such additional insured parties does not add to premiums
payable by the Partnership. 
 (d) The termination of any claim, action, suit, or proceeding by judgment, order, settlement,
conviction, or a plea of nolo contendere or its equivalent does not alone establish that a person seeking indemnification under this Section 5.5 is disqualified. Any person who is determined to be not entitled to indemnification under this
Section 5.5 may petition a court of competent jurisdiction for a determination that in view of all facts and circumstances that such person is fairly and equitably entitled to indemnity and the Partnership shall provide such indemnity as may be
determined proper by such court; provided, however, that the court has determined that such person has met the standard set forth in Section 5.5(a) above. 
 (e) Legal fees and expenses and other costs incurred as a result of a claim described in this Section 5.5(a) shall be paid by the Partnership from time to time in advance of the final disposition of
such claim if: (i) the claim relates to the performance or non-performance of duties or services by the Managing Partner or its Affiliates on behalf of the Partnership; (ii) the claim is initiated by a third party who is not an Investor
Partner, or the claim is initiated by an Investor Partner and a court of competent jurisdiction specifically approves such advancement; and (iii) the Managing Partner or such Affiliate undertakes to repay the advanced funds to the Partnership,
together with the applicable legal rate of interest thereon, in the event it is later determined that the Managing Partner or such Affiliate is not entitled to indemnification under the provisions of this Section 5.5(a). 

(f) To the extent that the Managing Partner or its Affiliates are successful on the merits or in defense of any claim, issue, or matter
therein, the Partnership shall indemnify the Managing Partner or its Affiliates, against the expenses, including attorneys’ fees, actually incurred by the Managing Partner or such Affiliate in connection therewith. 

(g) The indemnification provided by this Section 5.5 shall continue as to the Managing Partner and its Affiliates in the event it
ceases to be a managing partner of the Partnership with respect to claims relating to the period in which the Managing Partner was a managing partner of the Partnership and such indemnification shall inure to the benefit of the successors and
assigns of the Managing Partner and such Affiliates. 

  
 21 

 (h) The indemnification provided by this Section 5.5 shall be made, and shall be
recoverable by the Managing Partner or its Affiliates, only out of the tangible net assets of the Partnership and not from the Investor Partners. 
 Section 5.6 Reporting and Legal Expenses. The Partnership shall reimburse the Program Manager and the Managing Partner and its Affiliates for its share of the Reporting and Legal Expenses
incurred by the Program Manager, the Managing Partner, or any Affiliate thereof in managing and conducting the business and affairs of the Drilling Program or of the Partnership, as applicable. The Reporting and Legal Expenses reimbursed by the
Partnership shall be determined by the party seeking reimbursement in good faith and as being reasonable for such party. Such reimbursements shall be made periodically throughout the term of the Partnership. 

Section 5.7 Administrative Costs. The Partnership shall reimburse the Program Manager and the Managing Partner and its
Affiliates for all Administrative Costs and other costs and expenses incurred by the Program Manager, the Managing Partner, or any Affiliate thereof in managing and conducting the business and affairs relating to the Partnership’s interest in
the Drilling Program or of the Partnership, as applicable, including expenses incurred in providing or obtaining such professional, technical, administrative, and other services and advice as the Program Manager, the Managing Partner, or such
Affiliates may deem necessary or desirable. The general, administrative, and other costs reimbursed by the Partnership shall be determined by the party seeking reimbursement in good faith and as being reasonable for such party. The amount of
Administrative Costs that are to be reimbursed by the Partnership shall be determined and allocated to the Partnership and its Drilling Program consistent with applicable industry standards. Such reimbursements shall be made periodically throughout
the term of the Partnership. Such reimbursement obligation shall also apply to all Administrative Costs incurred by the Program Manager, the Managing Partner or any of its Affiliates on behalf of the Partnership or the Drilling Program from the
beginning of the calendar year in which the Partnership is formed to the date of the admission of the Investor Partners. Regardless of the actual amount of Administrative Costs incurred by the Managing Partner or Program Manager in connection with
the affairs of a Partnership, during any particular calendar year the total amount of Administrative Costs allocable to the Partnership shall not exceed the greater of (a) 3.5% of the Partnership’s gross revenues from the sale of oil and
natural gas production during such year (calculated without any deduction for Operating Costs or other costs and expenses) or (b) the sum of $50,000 plus .25% of the Capital Contributions of the Investor Partners to the Partnership. The above
limitation on Administrative Costs shall not be applicable to Administrative Costs otherwise allocable to the Partnership which are extraordinary and non-recurring or to the fixed overhead fee chargeable by an operator of Program Wells including the
fixed overhead fee chargeable under the Operating Agreement by MOC with respect to the Program Wells operated by the Program Manager or to costs categorized as Reporting and Legal Expenses. No portion of the salaries, benefits, compensation or
remuneration of the directors or of the executive officers of MOC or MD may be reimbursed as Administrative Costs. 
 An
independent certified public accountant shall provide annually to the Investor Partners, a written attestation to be included as part of the annual report required pursuant to Section 7.2 wherein such accountant shall verify that the method
used to make the allocations was consistent with the method described in this Agreement and that the total amount of costs allocated to the Investor Partners does not materially exceed amounts actually incurred by the Managing Partner. 

  
 22 

 Section 5.8 Management Fee. In consideration for services to be rendered by the
Managing Partner in managing the business of the Partnership during each of the initial three Partnership Years, the Partnership shall pay to the Managing Partner its share of a management fee in an amount equal to 1% of all Capital Contributions
initially made by the Investor Partners in exchange for their respective Interests as set forth in the Subscription Agreements (the “Management Fee”). The Management Fee payable during a particular Partnership Year shall not be deducted
from the Capital Contributions of the Investor Partners, but shall be paid by the Drilling Program in monthly or other periodic installments from funds which would otherwise be available for distribution to the Partners, and in such amounts as may
be determined in the discretion of the Managing Partner. To the extent that the Partnership has insufficient distributable funds during a particular Partnership Year to fully pay its share of the amount of the Management Fee payable during such
Partnership Year, then the amount of such unpaid Management Fee shall be carried forward and payable in the next succeeding Partnership Year. 
 Section 5.9 Gas Marketing Fee. In accordance with the terms of the Gas Marketing Agreement, in consideration for gas marketing services to be rendered by the Program Manager in connection with
the marketing of the Drilling Program’s natural gas, the Partnership shall pay its share of a gas marketing fee which is currently equal to $0.040 per MCF. This fee may be changed from time to time; provided, however, the Program Manager may
not charge the Partnership a gas marketing fee which is greater than other participants in a well. 
 Section 5.10
Restrictions on Certain Transactions. 
 (a) The Partnership may enter into contracts and agreements with the Managing
Partner and its Affiliates for the rendering of services and the sale, rental, or lease of supplies and equipment, provided that (i) such entity is engaged, independently of the Drilling Program and as an ordinary and ongoing business, in the
business of rendering such services or selling or leasing such equipment and supplies to a substantial extent to other persons in the industry in addition to programs in which the Managing Partner or its Affiliates have an interest and (ii) the
amount of the compensation, price, or rental that can be charged to the Partnership therefor must be no less favorable to the Partnership than that generally available (at the time the relevant contract or agreement was entered into) from unrelated
third parties in the area engaged in the business of rendering comparable services or selling, renting, or leasing comparable equipment and supplies which could reasonably be made available to the Partnership. If the Managing Partner or its
Affiliate is not engaged in the business as required by clause (i) of this Section 5.10(a) above, then such compensation, price, or rental shall be the cost of such services, equipment, or supplies to such entity, or the competitive rate
which could be obtained in the area, whichever is less. In addition, any drilling services rendered by the Managing Partner or its Affiliates to the Partnership shall be billed on a per foot, per day, or per hour rate, or some combination thereof.
All services for which the Managing Partner or its Affiliates are to receive compensation shall be embodied in written contracts which precisely describe the services to be rendered and all compensation to be paid. Advance payments to the Managing
Partner are prohibited, except where necessary to secure tax benefits of prepaid drilling costs. All contracts between the Partnership and the Managing Partner or its Affiliates shall be terminable by the Partnership (by a vote or written consent of
a Majority in Interest of the Investor Partners) without penalty upon 60 days’ written notice. 

  
 23 

 (b) The Partnership may borrow money on a non-recourse basis from the Managing Partner or
any of its Affiliates, provided that on any loans made available by the Managing Partner or any of its Affiliates to the Partnership, the Managing Partner or such Affiliate shall not receive interest in excess of the lesser of (i) the maximum
rate permitted by applicable law or (ii) the effective interest rate then being paid by the Managing Partner or such Affiliate for similar type borrowings. In no event shall any such loan bear interest in excess of the amount which would be
charged to the Partnership (without reference to the Managing Partner’s financial abilities or guaranties) by independent third parties for the same purpose. In connection with any loans to the Partnership by the Managing Partner or its
Affiliates, the Managing Partner or its Affiliates shall not receive points or other financing charges or fees, regardless of the amount. 
 (c) The Partnership shall acquire in certain instances interests in Prospects from the Managing Partner or its Affiliates on the terms and conditions set forth in the Program Agreement. 

(d) No Partnership Leases shall be farmed out by the Partnership unless the Managing Partner, exercising the standard of care of a normal
and prudent operator in the management of its own property, shall determine that either (i) the Partnership lacks sufficient funds for the drilling of a well on such Lease and cannot obtain suitable alternative financing for such drilling,
(ii) the Lease has been downgraded by events occurring after the acquisition thereof by the Partnership pursuant to the Program Agreement so that the drilling of a well on such Lease would no longer be desirable for the Partnership,
(iii) drilling on such Lease would result in an excessive concentration of Partnership funds, creating in the opinion of the Managing Partner undue risk to the Partnership and the Investor Partners, or (iv) the best interests of the
Partnership would be served by such farmout or other disposition. The Partnership may enter into a farmout agreement (in the capacity as either farmor or farmee) with the Managing Partner, any of its Affiliates, provided that the Managing Partner,
exercising the standards of a normal and prudent operator in the management of its own property, shall determine that the farmout is in the best interests of the Partnership and that the terms of any such farmout are consistent with and in any case
no less favorable to the Partnership than those utilized in the same geographic area for similar arrangements. The Partnership’s ability to enter into a farmout agreement with the Managing Partner or an Affiliate thereof is subject to the same
restrictions as its ability to purchase property from or sell property to the Managing Partner or an Affiliate thereof as provided in Section 5.10(c) and Section 5.10(f), respectively. 

(e) The Partnership shall make no loans to the Managing Partner or its Affiliates. 

  
 24 

 (f) The Partnership may sell or transfer its Leases to the Managing Partner or its
Affiliates, including Affiliated Programs, only pursuant to a transaction which is fair and reasonable to the Partnership and then subject to the following restrictions: 
 (i) A sale, transfer, or conveyance, including a farmout, of an undeveloped Lease (i.e., a Lease not having any Proved Developed Reserves attributable to it) from the Partnership to the Managing Partner
or any Affiliate thereof, other than an Affiliated Program, must be made at the higher of the Lease Acquisition Costs or fair market value. 
 (ii) A sale, transfer, or conveyance of a developed Lease (i.e., a property having Proved Developed Reserves attributable to it) from the Partnership to the Managing Partner or any Affiliate thereof,
other than an Affiliated Program in which the interest of the Managing General Partner or its Affiliate is substantially similar to or less than its interest in the Partnership, is not permitted except in connection with the liquidation of the
Partnership and then only at fair market value. 
 (iii) Except in connection with farmouts or joint ventures made in
compliance with the restrictions described in Section 5.10(d), a transfer of an undeveloped Lease from the Partnership to an Affiliated Program must be made at fair market value if the Lease has been held for more than two years; otherwise, if
the Managing Partner deems it to be in the best interests of the Partnership, the transfer may be made at the Lease Acquisition Costs. 
 (iv) Except in connection with farmouts or joint ventures made in compliance with the restrictions described in Section 5.10(d) above, a transfer of any Lease from the Partnership to an Affiliated
Production Purchase or Income Program must be made at fair market value if the Lease has been held for more than six months or there have been significant expenditures made in connection with the Lease; otherwise, if the Managing Partner deems it to
be in the best interests of the Partnership, the transfer may be made at the Lease Acquisition Costs as adjusted for intervening operations. 

A determination of fair market value as required by this paragraph (f) must be supported by an appraisal from an Independent Expert. Such opinion
and any associated supporting information will be maintained in the Partnership’s records for at least six years. 
 (g) No
rebates or give-ups may be received by the Managing Partner or any Affiliate, nor may the Managing Partner or any Affiliate participate in any reciprocal business arrangements which do not primarily benefit the Partnership. 

The Partnership will acquire only Leases that are reasonably required for the stated purpose of the Partnership, and no Leases will be
acquired for the purpose of subsequent sale or farmout, unless the acquisition of such property by the Partnership is made after a well has been drilled to a depth sufficient to indicate that such an acquisition is believed to be in the best
interests of the Partnership. 
 (h) Neither the Managing Partner, nor any Affiliate thereof, including an Affiliated Program,
shall be permitted to sell, transfer, or convey any Lease to the Partnership, directly or indirectly, except pursuant to a transaction which is fair and reasonable to the Partnership and in accordance with the following restrictions: 

(i) The Managing Partner and its Affiliates may only sell a Lease to the Partnership at a price equal to its Lease Acquisition Costs
unless the transferor has cause to believe that the Lease Acquisition Costs are materially more than the fair market value of such Lease, in which case such sale must be made at a price not in excess of its fair market value; provided, however, that
if the sale is from an Affiliated Program that has held the Lease for more than two years and in which Affiliated Program the interest of the Managing Partner or its Affiliate is substantially similar to, or less than, its interest in the
Partnership, the sale may be made at fair market value. 

  
 25 

 (ii) If the Managing Partner, or an Affiliate thereof, sells any Lease within a Prospect to
the Partnership, it must, at the same time, sell to the Partnership an equal proportionate interest in all other Leases that it owns in the same Prospect. 
 (iii) If at any time within a period of five years from the creation of the Partnership, the Managing Partner or an Affiliate thereof proposes to acquire an interest from a non-Affiliated person in a
Prospect in which the Partnership possesses an interest or in a Prospect in which the Partnership’s interest has been terminated without compensation within one year preceding such proposed acquisition, the following conditions will apply:
(A) if the Managing Partner or any Affiliate thereof does not currently own property in the Prospect separately from the Partnership, then neither the Managing Partner nor any Affiliate thereof will be permitted to purchase an interest in the
Prospect and (B) if the Managing Partner or any Affiliate thereof currently owns a proportionate interest in the Prospect separately from the Partnership, then the interest to be acquired will be divided between the Partnership and the Managing
Partner, or an Affiliate thereof in the same proportion as is the other property in the Prospect; provided, however, if cash or financing is not available to the Partnership to enable it to consummate a purchase of the additional interest to which
it is entitled, then the Managing Partner or any Affiliate thereof may purchase additional interest in the Prospect during such five year period. 
 (iv) If the area constituting a Partnership’s Prospect is subsequently enlarged to encompass any area wherein the Managing Partner or any Affiliate thereof owns a separate Lease, such separate Lease
or a portion thereof must be sold, transferred, or conveyed to the Partnership, in accordance with the provisions described in this Section 5.10(h), if the activities of the Partnership were material in establishing the existence of Proved
Undeveloped Reserves which are attributable to such Lease. 
 (v) Except for the carried interests created by the Program
Agreement, a sale, transfer, or conveyance to the Partnership of less than all of the ownership of the Managing Partner or any Affiliate thereof in any Lease is prohibited unless the interest retained by the Managing Partner or such Affiliate is a
proportionate Working Interest, the respective obligations of the Managing Partner, or such Affiliate and the Partnership are substantially the same after the sale of the interest by the Managing Partner or such Affiliate and its interest in
revenues does not exceed the amount proportionate to its retained Working Interest. Except for the carried interests created by the Program Agreement, neither the Managing Partner nor any Affiliate thereof may retain any Overriding Royalty Interest
or other burden on an interest conveyed to the Partnership. 
 (vi) For the purposes of the preceding four paragraphs, the term
“Affiliate” does not include an Affiliated Program in which the interest of the Managing Partner or an Affiliate thereof is substantially similar to or less than its interest in the Partnership. 

  
 26 

 (vii) If the Partnership acquires a Lease pursuant to a farmout or joint venture from an
Affiliated Program, the Managing Partner’s, and any Affiliate’s thereof aggregate compensation associated with the property and any direct or indirect ownership interest in the property may not exceed the lower of the compensation and
ownership interest the Managing Partner, and such Affiliates could receive if the property were separately owned or retained by either the Partnership or such other Affiliated Program. 
 A determination of fair market value as required by this paragraph (h) must be supported by an appraisal from an Independent Expert. Such opinion and any associated supporting information will be
maintained in the Partnership’s records for at least six years. 
 (i) If the Partnership participates in other
partnerships or joint ventures (multi-tier arrangements), the terms of any such arrangements shall not result in the circumvention of any of the requirements or prohibitions contained in this Partnership Agreement, including the following:

 (i) there will be no duplication or increase in the Managing Partner’s compensation, Partnership expenses, or other
fees and costs; 
 (ii) there will be no substantive alteration in the fiduciary and contractual relationship between the
Managing Partner and the Investor Partners; and 
 (iii) there will be no diminishment in the voting rights of the Investor
Partners. 
 (j) In connection with a proposed Roll-Up, the following shall apply: 

(i) An appraisal of all Partnership assets shall be obtained from a competent Independent Expert. If the appraisal will be included in a
prospectus used to offer the securities of a Roll-Up Entity, the appraisal shall be filed with the Securities and Exchange Commission as an exhibit to the registration statement for the offering. The appraisal shall be based on all relevant
information, including current reserve estimates prepared by an independent petroleum consultant, and shall indicate the value of the Partnership’s assets assuming an orderly liquidation as of a date immediately prior to the announcement of the
proposed Roll-Up transaction. The appraisal shall assume an orderly liquidation of Partnership assets over a 12-month period. The terms of the engagement of the Independent Expert shall clearly state that the engagement is for the benefit of the
Partnership and the Investor Partners. A summary of the independent appraisal, indicating all material assumptions underlying the appraisal, shall be included in a report to the Investor Partners in connection with a proposed Roll-Up. 

(ii) In connection with a proposed Roll-up, Investor Partners who vote “no” on the proposal shall be offered the choice of:

 (a) accepting the securities of the Roll-Up Entity; 

(b) either (A) remaining as Limited Partner or General Partner in the Partnership and preserving his or her interest
in the Partnership on the same terms and conditions as existed previously, or (B) receiving cash in an amount equal to his or her pro-rata share of the appraised value of the net assets of the Partnership. 

  
 27 

 (iii) The Partnership shall not participate in any proposed Roll-Up which, if approved,
would result in the diminishment of any Investor Partner’s voting rights under the Roll-Up Entity’s chartering agreement. In no event shall the democracy rights of Investor Partners in the Roll-Up Entity be less than those provided for
under Sections 6.4 and 6.5 of this Agreement. If the Roll-Up Entity is a corporation, the democracy rights of Investor Partners shall correspond to the democracy rights provided for in this Agreement to the greatest extent possible. 

(iv) The Partnership shall not participate in any proposed Roll-Up transaction which includes provisions which would operate to
materially impede or frustrate the accumulation of shares by any purchaser of the securities of the Roll-Up Entity (except to the minimum extent necessary to preserve the tax status of the Roll-Up Entity); nor shall the Partnership participate in
any proposed Roll-Up transaction which would limit the ability of an Investor Partner to exercise the voting rights of its securities of the Roll-Up Entity on the basis of the number of Partnership Interests held by that Investor Partner.

 (v) The Partnership shall not participate in a Roll-Up in which Investor Partners’ rights of access to the records of
the Roll-Up Entity will be less than those provided for under Section7.1(a) and (b) of this Agreement. 
 (vi) The
Partnership shall not participate in any proposed Roll-Up transaction in which any of the costs of the transaction would be borne by the Partnership if less than a Super Majority in Interest of the Investor Partners vote to approve the proposed
Roll-Up. 
 (vii) The Partnership shall not participate in a Roll-Up transaction unless the Roll-Up transaction is approved by
a Super Majority in Interest. 
 (k) Turnkey drilling contracts or other contracts with the Managing Partner or its Affiliates
that establish a fixed price for drilling services shall not be permitted. 
 (l) Neither the Managing Partner nor any Affiliate
thereof shall profit by causing the Partnership to engage in drilling in contravention of the Managing Partner’s fiduciary obligations to the Partnership. 
 To the extent the restrictions set forth above apply to the Managing Partner or its Affiliates and except as otherwise provided herein, the term “Affiliate” includes, but is not limited to, MOC
in its capacity as Program Manager. Except as otherwise set forth in this Section 5.10 of the Partnership Agreement, the Managing Partner and its Affiliates may pursue business opportunities that are consistent with the Partnership’s
investment objectives for their own account only after they have determined that such opportunity either cannot be pursued by the Partnership because of insufficient funds or because it is not appropriate for the Partnership under the existing
circumstances. 

  
 28 

 Section 5.11 Restriction on Voting Interests Held by Managing Partner. Interests
owned by the Managing Partner or its Affiliates shall have full voting rights under this Agreement. In addition, none of the Interests owned by the Managing Partner or its Affiliates shall be counted for voting purposes or for purposes of
determining a quorum or have any voting rights under this Agreement concerning the removal of the Managing Partner or any transaction between the Partnership and the Managing Partner or its Affiliates. 

Section 5.12 Tax Elections. The Managing Partner shall make the following elections on behalf of the Partnership: 

(a) to elect, in accordance with Section 263(c) of the Code and applicable regulations and comparable state law provisions, to
deduct as an expense all intangible drilling and development costs with respect to productive and nonproductive wells and the preparation of wells for the production of oil or gas; 

(b) to elect the calendar year as the Partnership’s fiscal year; 

(c) to elect the accrual method of accounting; 
 (d) to elect, in accordance with Section 709(b) of the Code and applicable regulations and comparable state law provisions, to amortize and deduct organization expenses (as such term is defined in
Section 709 of the Code) over a period of 60 months beginning with the month in which the Partnership begins business; and 

(e) to elect with respect to such other federal, state, and local tax matters as the Managing Partner deems advantageous to the
Partnership; provided that no election shall be made by the Partnership in accordance with Section 754 of the Code and applicable regulations and comparable state law provisions without the consent of the Managing Partner, the granting or
denying of which consent shall be in its sole and absolute discretion. 
 Section 5.13 Tax Matters Partner. The
Managing Partner shall be designated the tax matters partner (in this Section 5.13 called the “TMP”) as defined in Section 6231(a)(7) of the Code with respect to operations conducted by the Partners pursuant to this Agreement.
The TMP is authorized to take such actions and to execute and file all statements and forms on behalf of the Partnership which may be permitted or required by the applicable provisions of the Code or Treasury Regulations issued thereunder, and the
Investor Partners will take all other action that may be necessary or appropriate to effect the designation of the Managing Partner as the TMP. In the event of an audit of the Partnership’s income tax returns by the Internal Revenue Service,
the TMP may, at the expense of the Partnership, retain accountants and other professionals to participate in the audit. All expenses incurred by the TMP in its capacity as such shall be expenses of the Partnership and shall be paid by or reimbursed
to the TMP from Partnership funds. 
 ARTICLE VI 
 RIGHTS AND OBLIGATIONS OF INVESTOR PARTNERS 
 Section 6.1 Rights of
Investor Partners. In addition to any other rights specifically set forth herein, all Investor Partners shall have the right to: (a) have the Partnership books kept at the principal place of business of the Partnership and upon adequate
written notice at all reasonable times inspect and, at such Investor Partner’s expense, copy any of them personally or through a representative; (b) have on demand true and full information of all things affecting the Partnership and a

 29 

 Section 6.2 Access of Investor Partners to Geophysical Data. During the term of
the Partnership, the Partnership may acquire or have access to geophysical, geological, and other similar data and information. Each Investor Partner shall during the term of the Partnership have the right, after adequate notice, during normal
business hours at the offices of the Partnership to inspect and review all such data and information and studies, maps, evaluations, or reports derived therefrom and material related thereto which are attributable to the Partnership properties and
are in the actual custody of the Managing Partner; provided, however, that the Managing Partner may refuse for a reasonable period of time to grant a Investor Partner access to such data and information and studies, maps, evaluations, and reports
which the Managing Partner (a) has agreed to keep confidential or (b) determines in good faith should be kept confidential considering the interests of the Partnership and each of its Partners. 

Section 6.3 Return of Capital Contribution. No Investor Partner shall be entitled to (a) withdraw from the Partnership
except upon assignment by an Investor Partner of his Interests and the substitution of such Investor Partner’s assignee as a substituted Investor Partner of the Partnership in accordance with Section 8.1 or as required by law, or
(b) the return of his Capital Contribution except (i) as otherwise provided in this Agreement or as required by law, (ii) to the extent, if any, that distributions made pursuant to the express terms of this Agreement may be considered
as such by law or by unanimous agreement of the Partners, or (iii) upon dissolution of the Partnership, and then only to the extent expressly provided for in this Agreement and as permitted by law. 

Section 6.4 Meetings. Meetings of the Partners may be called by the Managing Partner at any time and from time to time or may
be called by Investor Partners whose combined Sharing Ratios equal at least 10%. The Managing Partner shall, within 15 days after its receipt of a written request for any such call by Investor Partners for a Partners’ meeting, give all Investor
Partners written notice of the time, place, and purpose of such meeting. The meeting shall be held at a reasonable time and place on a date not less than 30 nor more than 60 days after the date of the mailing of such notice; provided that the date
for notice of such a meeting may be extended for a period of up to 60 days, if in the opinion of the Managing Partner such additional time is necessary to permit preparation of proxy or information statements or other documents required to be
delivered in connection with such meeting by the Securities and Exchange Commission, state securities administrators or other regulatory authorities. The Partners may conduct any Partnership business at such meeting which is permitted under this
Agreement and is specified in such notice. Investor Partners may vote in person or by proxy at any such meeting, and the presence in person or by proxy of a Majority in Interest of the Investor Partners shall be necessary to constitute a quorum for
the transaction of business at such meeting. 
 Section 6.5 Voting Rights of Investor Partners. Except as otherwise
provided in Section 5.2(b) and 5.10(j), any vote, consent, approval, election, or other action by the Investor Partners on or with respect to any Partnership matter (including, without limitation, those matters set forth in Sections 5.2(c),
5.2(e), 8.6(a), 8.6(b), 9.1(b), 9.3(a) and 11.2) shall be duly and validly made only if made by a Majority in Interest of the Investor Partners (without the necessity for the concurrence by the Managing Partner), and in the event of any such vote,
consent, approval, or election, each Investor Partner that does not vote for, consent to, approve of, or elect with respect to such matter hereby agrees to be bound by the decision of a Majority in Interest of the Investor Partners and hereby
approves such matter to the extent such approval is required for such matter to be effective under the Delaware Act or any other applicable law, rule, or regulation. 

  
 30 

 Section 6.6 Conduct of Meeting. The Managing Partner shall have full power and

the requirements of Section 6.4, the conduct of voting, the validity and effect of any proxies, votes, or consents, and the determination of any controversies, votes, or challenges arising in connection with or during the meeting or voting. The
Managing Partner shall designate a person to serve as chairman of any meeting and shall further designate a person to take the minutes of any meeting, in either case, including without limitation, a partner or a director or an officer of the
Managing Partner. All minutes shall be kept with the records of the Partnership maintained by the Managing Partner. The Managing Partner may make such other regulations consistent with applicable law and this Agreement as it may deem advisable
concerning the conduct of any meeting of the Investor Partners or solicitation of consents in writing, including regulations in regard to the appointment of proxies, the appointment and duties of inspectors of votes and consents, the submission and
examination of proxies and other evidence of the right to vote, and the revocation of consents in writing. 
 Section 6.7
General Partners Not Agents. Pursuant to Section 5.1 the General Partners have elected to delegate to the Managing Partner authority to manage, control, and administer and operate the property, business, and affairs of the Partnership.
Each General Partner agrees that no General Partner or group of General Partners constituting less than a Majority in Interest may cause the Managing Partner on behalf of the Partnership to act as agent for the Partnership, execute documents on
behalf of the Partnership, convey Partnership property, or take any other action binding on the Partnership. Each General Partner further agrees that in no circumstance will a Partner other than the Managing Partner have the right to act as agent
for the Partnership, execute documents on behalf of the Partnership, convey Partnership property, or take any other action binding on the Partnership. Any General Partner who takes action contravening this Section 6.7 agrees to indemnify the
Partnership and all other Partners from any loss, liability, or expense caused by such action. 
 Section 6.8
Liabilities of Partners. 
 (a) Pursuant to the Delaware Act, the General Partners are liable jointly and severally for
all liabilities and obligations of the Partnership. Notwithstanding the foregoing, as among themselves, the General Partners hereby agree that each shall be solely and individually responsible only for his pro rata share (based on Capital
Contributions made) of the liabilities and obligations of the Partnership, and any General Partner who incurs liability in excess of his pro rata share shall be entitled to contribution from the other General Partners. Pursuant hereto, the Managing
Partner further agrees to indemnify each General Partner for any and all Partnership-related obligations and liabilities otherwise allocable to or paid by such General Partner which are in excess of such General Partner’s share of the
Partnership’s undistributed assets. Under no circumstances shall any Partner be required to indemnify the Managing Partner, except to the extent of such Partner’s (i) Capital Contribution and (ii) share of Partnership assets.

  
 31 

 (b) The Partnership may purchase and maintain insurance on behalf of all Partners against
any liabilities asserted against or expenses incurred by the Partners in connection with Partnership activities, provided that the Partnership shall not incur the costs of that portion of such insurance, if any, which insures the Managing Partner
for any liability with respect to which the Managing Partner is denied indemnification under the provisions of this Agreement. Such insurance may be in such amounts as the Managing Partner shall determine is sufficient to protect the Partners from
the maximum amount of such liabilities and expenses. 
 ARTICLE VII 

BOOKS, RECORDS, CAPITAL ACCOUNTS, REPORTS, AND BANK ACCOUNTS 

Section 7.1 Books, Records, and Capital Accounts. 
 (a) The Managing Partner shall keep just and true records and books of account with respect to the operations of the Partnership and shall maintain and preserve during the term of the Partnership and for
four years thereafter all such records, books of account, and other relevant Partnership documents. The Managing Partner shall maintain for at least six years all records necessary to substantiate the fact that Interests were sold only to purchasers
for whom such Interests were suitable. Such books shall be maintained at the principal place of business of the Partnership and shall be kept on the accrual method of accounting. 

(b) Any records maintained by the Partnership in the regular course of its business, including the names and addresses of Investor
Partners, books of account and records of Partnership proceedings, may be kept on or be in the form of magnetic tape, photographs, micrographics, or any other information storage device, provided that the records so kept are convertible into clearly
legible written form within a reasonable period of time. An alphabetical list of the names, addresses, and business telephone numbers of the Investor Partners of the Partnership along with the number of Interests held by each of them (the
“participant list”) shall be maintained as a part of the books and records of the Partnership and shall be available for the inspection by any Investor Partner or his designated agent at the principal office of the Partnership upon the
request of the Investor Partner. The participant list shall be updated at least quarterly to reflect changes in the information contained therein. It shall be a defense that the actual purpose and reason for the requests for inspection or for a copy
of the participant list is to secure the list of Investor Partners or other information for the purpose of selling such list or information or copies thereof, or of using the same for a commercial purpose other than in the interest of the applicant
as an Investor Partner relative to the affairs of the Partnership. The remedies provided hereunder to Investor Partners requesting copies of the participant list are in addition to, and shall not in any way limit, other remedies available to
Investor Partners under federal law or the laws of any state. 

  
 32 

 (c) An individual capital account shall be maintained by the Partnership for each Partner as
provided below: 
 (i) The capital account of each Partner shall, except as otherwise provided herein, be (A) credited by
such Partner’s Capital Contributions when made, (B) credited by the fair market value of any property contributed to the Partnership by such Partner (net of liabilities secured by such contributed property that the Partnership is
considered to assume or take subject to under Section 752 of the Code), (C) credited with the amount of any item of taxable income or gain and the amount of any item of income or gain exempt from tax allocated to such Partner,
(D) credited with the Partner’s share of Simulated Gain as provided in Section 7.1(c)(ii), (E) debited by the amount of any item of tax deduction or loss allocated to such Partner, (F) debited by the Partner’s share of
Simulated Depletion and Simulated Loss as provided in Section 7.1(c)(ii), (G) debited by such Partner’s allocable share of expenditures of the Partnership not deductible in computing the Partnership’s taxable income and not
properly chargeable as Capital Expenditures, including any non-deductible book amortizations of capitalized costs, and (H) debited by the amount of cash or the fair market value of any property distributed to such Partner (net of liabilities
secured by such distributed property that such Partner is considered to assume or take subject to under Section 752 of the Code). Immediately prior to any distribution of property by the Partnership that is not pursuant to a liquidation of the
Partnership, the Partners’ capital accounts shall be adjusted by (A) assuming that the distributed assets were sold by the Partnership for cash at their respective fair market values as of the date of distribution by the Partnership and
(B) crediting or debiting each Partner’s capital account with its respective share of the hypothetical gains or losses resulting from such assumed sales determined in the same manner as gains or losses provided for under Sections 4.2 and
7.1(c)(ii) for actual sales of such properties. 
 (ii) The allocation of basis prescribed by Section 613A(c)(7)(D) of the
Code and provided for in Section 4.2(g) and each Partner’s separately computed depletion deductions shall not reduce such Partner’s capital account, but such Partner’s capital account shall be decreased by an amount equal to the
product of the depletion deductions that would otherwise be allocable to the Partnership in the absence of Section 613A(c)(7)(D) of the Code (computed without regard to any limitations which theoretically could apply to any Partner) times such
Partner’s percentage share of the adjusted basis of the property with respect to which such depletion is claimed (herein called “Simulated Depletion”). The Partnership’s basis in any oil or gas property as adjusted from time to
time for the Simulated Depletion allocable to all Partners (and where the context requires, each Partner’s allocable share thereof) is herein called “Simulated Basis.” No Partner’s capital account shall be decreased, however, by
Simulated Depletion deductions attributable to any depletable property to the extent such deductions exceed such Partner’s remaining Simulated Basis in such property. Upon the sale or other disposition of an interest in a depletable property,
each Partner’s capital account shall be credited with the gain (“Simulated Gain”) or debited with the loss (“Simulated Loss”) determined by subtracting from his allocable share of the amount realized on such sale or
disposition his Simulated Basis, as adjusted by Simulated Depletion. 
 (iii) Adjustments of basis of Partnership property
provided for under Sections 734 and 743 of the Code and comparable provisions of state law (resulting from an election under Section 754 of the Code or comparable provisions of state law) and elections by individual Partners under
Section 59(e)(4) of the Code to capitalize and amortize such Partner’s share of intangible drilling and development costs shall not affect the capital accounts of the Partners, and the Partners’ capital accounts shall be debited or
credited pursuant to the terms of this Section 7.1 as if no such election had been made, unless otherwise required by applicable Treasury Regulations. 

  
 33 

 (iv) Capital accounts shall be adjusted, in a manner consistent with this Section 7.1,
to reflect any adjustments in items of Partnership income, gain, loss, or deduction that result from amended returns filed by the Partnership or pursuant to an agreement by the Partnership with the Internal Revenue Service or a final court decision.

 (v) In the case of property contributed to the Partnership by a Partner, the Partners’ capital accounts shall be
debited or credited for items of depreciation, cost recovery, Simulated Depletion, amortization, and gain or loss with respect to such property computed in the same manner as such items would be computed if the adjusted tax basis of such property
were equal to its fair market value on the date of its contribution to the Partnership, in lieu of the capital account adjustments provided above for such items, all in accordance with Treasury Regulation 1.704-1(b)(2)(iv)(g). 

(vi) It is the intention of the Partners that the capital account of each Partner be kept in the manner required under Treasury
Regulation 1.704-1(b)(2)(iv). To the extent any additional adjustment to the capital accounts is required by such regulation, the Managing Partner is hereby authorized to make such adjustment after notice to the General Partners. 

Section 7.2 Reports. The Managing Partner shall deliver to each Investor Partner the following financial statements and
reports at the times indicated below: 
 (a) Semiannually within 75 days after the end of the first six months of each fiscal
year and annually within 120 days after the end of each fiscal year, financial statements, including a balance sheet and statements of income, Partners’ equity, and cash flow, all of which shall be prepared in accordance with generally accepted
accounting principles. The annual financial statements shall be accompanied by a report of an independent certified public accountant designated by the Managing Partner, stating that an audit of such financial statements has been made in accordance
with generally accepted auditing standards and that in its opinion such financial statements present fairly the financial condition, results of operations, and cash flows of the Partnership in accordance with generally accepted accounting principles
consistently applied. 
 (b) Annually by March 15 of each year or as soon thereafter as is reasonably possible, a report
containing such information as may be needed to enable each Investor Partner to prepare and file his federal income tax return and any required state income tax return. 

  
 34 

 (c) Annually within 120 days after the end of each fiscal year beginning with the fiscal
year ended December 31 of the year following the year in which the Partnership commences operation, (i) a summary of the computations of the total estimated oil and gas Proved Reserves of the Partnership as of the end of such fiscal year
and the dollar value thereof at then existing prices and a computation of each Investor Partner’s interest in such value, such reserve computations to be based upon engineering reports prepared by qualified independent petroleum engineers,
(ii) an estimate of the time required for the extraction of such Proved Reserves and the present worth thereof (discounted at a rate generally accepted in the oil and gas industry and undiscounted), and (iii) a statement that because of
the time period required to extract such reserves the present value of revenues to be obtained in the future is less than if such revenues were immediately receivable. Each such report shall be prepared in accordance with customary and generally
accepted standards and practices for petroleum engineers and shall be prepared by a recognized independent petroleum engineer selected from time to time by the Managing Partner. No later than 90 days following the occurrence of an event resulting in
a reduction in an amount of 10% or more of the estimated value of the oil and gas Proved Reserves as last reported to the Investor Partners, other than a reduction resulting from normal production, sales of reserves or product price changes, a new
summary conforming to the requirements set forth above in this Section 7.2(c) shall be delivered to the Investor Partners. 

(d) Semiannually within 75 days after the end of the first six months of each fiscal year and annually within 120 days after the end of
each fiscal year, (i) a summary itemization, by type or classification, of any transaction of the Partnership since the date of the last such report with the Managing Partner or any Affiliate thereof and the total fees, compensation, and
reimbursement paid by the Partnership (or indirectly on behalf of the Partnership) to the Managing Partner and its Affiliates, including without limitation, the average price paid by any Affiliate of the Managing Partner during the two most recent
calendar quarters for oil and gas produced by Program Wells purchased by such Affiliate and the highest average price paid by any other substantial purchaser of comparable oil or gas produced in the field where such Program Wells are located, and
(ii) a schedule reflecting (A) the total costs of the Partnership (and, where applicable, the costs pertaining to each Prospect) and the costs paid by the Managing Partner and by the Investor Partners, (B) the total revenues of the
Partnership and the revenues received by or credited to the accounts of the Managing Partner and the Investor Partners, (C) a reconciliation of (x) the total costs of the Partnership paid by the Managing Partner and the Investor Partners
to (y) the allocation of such costs set forth in the Program Agreement and (D) a reconciliation of (x) the total revenues received by or credited to the accounts of the Managing Partner and the Investor Partners to (y) the
allocation of such revenues set forth in the Program Agreement. Each semi-annual report delivered by the Managing Partner may contain summary estimates of the information described in subdivision (i) of this Section 7.2(d). 

(e) Monthly within 30 days after the end of each calendar month while the Partnership is participating in the drilling and completion of
wells in which it has an interest until the end of such activity, and thereafter for a period of three years semiannually within 75 days after the end of the first six months of each fiscal year and annually within 120 days after the end of each
fiscal year, (i) a description of each Prospect or field in which the Partnership owns Leases (provided that after the initial description of each such Prospect or field has been provided to the Investor Partners only material changes, if any,
with respect to such Prospect or field need be described), (ii) a description of all farmouts entered into by the Partnership since the date of the last such report, including the reason therefor, the location and timing thereof, the parties to
the farmout and the terms thereof, and (iii) a summary of the wells drilled by the Partnership and the status thereof, indicating whether each of such wells is being drilled or has been completed or plugged and abandoned, a statement of the
cost of each well completed or abandoned, and the reason for abandoning any well after commencement of production. Each report delivered by the Managing Partner may contain summary estimates of the information described in clause (iii) of this
Section 7.2(e). 

  
 35 

 (f) Such other reports and financial statements as the Managing Partner shall determine from
time to time. 
 The cost of such reporting shall be paid by the Partnership as a Partnership expense. 

Section 7.3 Bank Accounts. The Managing Partner shall cause one or more accounts to be maintained in a state or federally
chartered bank or savings and loan association, which accounts shall be used for the payment of the expenditures incurred by the Managing Partner in connection with the business of the Partnership, and in which shall be deposited any and all
receipts of the Partnership. All such amounts shall be and remain the property of the Partnership and shall be received, held, and disbursed by the Managing Partner for the purposes specified in this Agreement. There shall not be deposited in any of
said accounts any funds other than funds belonging to the Partnership, and no other funds shall in any way be commingled with such funds. The Managing Partner may invest Partnership funds which they deem untimely or inappropriate to use or commit
for Partnership purposes or to distribute to the Partners in such United States Treasury Bills, other short-term governmental obligations or bank certificates of deposit or other certificates, securities or evidences of indebtedness on such terms
and for such security, if any, as they may deem necessary or desirable. The Managing Partner shall have a fiduciary responsibility for the safekeeping and use of all funds and assets of the Partnership, whether or not in the Managing Partner’s
possession or control, and shall not employ or permit another to employ such funds or assets in any manner except for the benefit of the Partnership. 
 ARTICLE VIII 
 ASSGNMENT AND PURCHASE OF INTERESTS; SUBSTITUTION

 Section 8.1 Assignments by Investor Partners. 

(a) The interest of any Investor Partner in the Partnership shall be assignable, in whole or in part, subject to the following:

 (i) No such assignment shall be made if, in the opinion of counsel to the Partnership, such assignment would cause the
termination of the Partnership for federal income tax purposes under Section 708 of the Code or might result in a change in the status of the Partnership to a “publicly traded partnership” within the meaning of Section 7704 of
the Code, unless the Managing Partner consents to such assignment, or if in the opinion of counsel to the Partnership such assignment may not be effected without registration under the Securities Act, or would result in the violation of any
applicable state securities laws; 
 (ii) The Partnership shall not be required to recognize any such assignment until the
instrument conveying such interest has been delivered to the Managing Partner for recordation on the books of the Partnership; 

(iii) Unless an assignee becomes a substituted Investor Partner in accordance with the provisions set forth below, such assignee shall
not be entitled to any of the rights granted to an Investor Partner hereunder, other than the right to receive all or part of the share of the profits, losses, cash distributions, or returns of capital to which his assignor would otherwise be
entitled; 

  
 36 

 (iv) Except as required by law or in unusual circumstances when consented to by the
Managing Partner, the assigning Investor Partner (A) may not assign less than its whole Interest to any person other than the Partnership, the Managing Partner, an Affiliate thereof, or a third person designated by the Managing Partner in its
sole discretion, and (B) must retain at least a whole Interest, in the event fewer than all such Investor Partner’s Interests are assigned to any person other than the Partnership, Managing Partner, an Affiliate thereof, or a third person
designated by the Managing Partner in its sole discretion; and 
 (v) The assignor shall notify the Managing Partner of such
assignment and provide the Managing Partner with such information regarding the transferee and the transfer (including without limitation, the name, address, and taxpayer identification number of the transferor and transferee and the date of the
transfer) as is required under Section 6050K of the Code (if the transfer is a sale or exchange described in Section 751(a) of the Code) and Section 6112 of the Code (relating to tax shelter investor lists) and Treasury Regulations
promulgated thereunder by the Internal Revenue Service in the manner and at the time prescribed by law. 
 An assignment by an Investor Partner
in violation of clause (i) or clause (ii) of this Section 8.1(a) shall be void and ineffectual and shall not bind the Partnership or any other Partner. The assignee of an Investor Partner’s interest in the Partnership shall pay
all costs and expenses incurred by the Partnership in connection with such assignment, which costs and expenses shall not be less than $50. In the discretion of the Managing Partner, such costs and expenses may be collected out of revenues otherwise
allocable to such assignee under this Agreement. 
 (b) An assignee of the interest of an Investor Partner, or any portion
thereof if permitted hereunder, shall become a substituted Investor Partner entitled to all the rights of an Investor Partner if, and only if: 
 (i) The assignor gives the assignee such right; 
 (ii) The Managing Partner
consents to such substitution, which consent may only be withheld to the extent legally necessary (as set forth in an opinion of counsel) to preserve the tax status of the Partnership or the classification of Partnership income for tax purposes;

 (iii) The assignee pays to the Partnership all costs and expenses incurred in connection with such substitution; including
without limitation, costs incurred in amending filings referred to in Section 1.7, which costs and expenses, in the discretion of the Managing Partner, may be collected out of revenues otherwise allocable to such substituted Investor Partner
under this Agreement; 
 (iv) The assignee executes and delivers such instruments, in form and substance satisfactory to the
Managing Partner, as the Managing Partner may deem necessary or desirable to effect such substitution and to confirm the agreement of the assignee to be bound by all of the terms and provisions of this Agreement; and 

  
 37 

 (v) The assignee delivers to the Managing Partner a written representation as to each of
the matters set forth in the Subscription Agreement. 
 The consent of the Investor Partners shall not be required for admission to the
Partnership of a substituted Investor Partner who meets the above requirements. The Partnership and the Managing Partner shall be entitled to treat the record owner of any Partnership interest as the absolute owner thereof in all respects, and shall
incur no liability for distributions of cash or other property made in good faith to such record owner until such time as a written assignment of such interest has been received and accepted by the Managing Partner and recorded on the books of the
Partnership. In no event shall any Partnership interest, or any portion thereof, be sold, transferred, or assigned to a minor or incompetent or any other person not qualified to become an Investor Partner hereunder, and any such attempted sale,
transfer, or assignment shall be void and ineffectual and shall not bind the Partnership or the Managing Partner. Unless an assignee becomes a substituted Investor Partner, any assignment by the assigning Investor Partner of the right to receive
Partnership distributions shall not release such Investor Partner of any obligations connected with the interest in the Partnership being assigned. In no event shall any purported transfer, by operation of law or otherwise, require the accounting by
the Managing Partner to more than one person with respect to the Partnership interest transferred unless the transfer is consented to by the Managing Partner in accordance with the foregoing and the Partnership interest transferred represents a
whole number of Interests owned by the Investor Partner. The effective date of any assignment shall be the date on which all of the prerequisites to the assignment specified in this Section 8.1 have been met. The Partnership will amend its
records at least once each calendar quarter to effect the substitution of substituted partners. In the case of assignments where the assignee does not become a substituted Investor Partner, the Partnership shall recognize the assignment not later
than the last day of the calendar month following receipt of the notice of assignment and the required documentation. 

Section 8.2 Assignment by Managing Partner. 
 (a) The interest of the Managing Partner in the Partnership shall not be assignable, in whole or in part, except in the event of the following assignments: 

(i) A disposition by the Managing Partner of all or any portion of its Partnership interest to one or more Affiliates of the Managing
Partner that agree to assume all or a proportionate part of the obligations of the Managing Partner with respect to such interest in the Partnership; 
 (ii) A disposition by the Managing Partner of all or any part of its Partnership interest to one or more persons that have as the result of a merger, consolidation, corporate reorganization, or other
transaction acquired all or substantially all of the assets of the Managing Partner and have assumed the obligations of the Managing Partner hereunder; or 
 (iii) An assignment or transfer by the Managing Partner of all or any portion of its Partnership interest by way of mortgage, pledge, or charge as security for an advance of monies to it, provided that
the mortgagee or pledgee shall hold such interest subject to all of the terms of this Agreement. 

  
 38 

 (b) In the event of a disposition, assignment, or transfer referred to in clause (i) or
clause (ii) of Section 8.2(a), such successor, assignee, or transferee shall be and become a substituted Managing Partner and shall continue the business of the Partnership without the occurrence of any dissolution and the assigning
Managing Partner shall be released from all of its obligations thereafter arising hereunder; and each Investor Partner (and any person who hereafter becomes a substituted Investor Partner by his execution, adoption, or acceptance of this Agreement)
does hereby consent to the admission of such successor, assignee, or transferee as a substituted Managing Partner to the extent required by the Delaware Act and to the continuance of the business of the Partnership by such substituted Managing
Partner, and authorizes the Managing Partner or substituted Managing Partner to ratify on his behalf pursuant to the power of attorney granted in Section 10.2 such Investor Partner’s consent to the admission of the new Managing Partner as
a Managing Partner of the Partnership. 
 (c) The Partnership shall take such actions as the Managing Partner in its sole
discretion deems necessary or appropriate to effect or facilitate a disposition, assignment, or transfer referred to in Section 8.2(a), including without limitation, providing notice thereof to the Investor Partners and entering into
appropriate escrow arrangements; provided, however, that no such disposition, assignment, or transfer (in the absence of the bankruptcy, withdrawal, removal, or dissolution of a Managing Partner) shall result in dissolution of the Partnership.

 (d) Except as otherwise provided in Section 8.2(b), Section 8.6 or Section 9.3, no assignee or transferee of a
Managing Partner shall become a substituted Managing Partner without the written consent of all of the Investor Partners. 

Section 8.3 Right of Presentment. During the first calendar quarter of each of the years 2014 through 2019, an Investor
Partner (other than the Managing Partner or an Affiliate thereof) may request in writing that the Managing Partner repurchase all, but not less than all, of his Interests (the “Right of Presentment”). The repurchase price to be paid upon
any repurchase of an Investor Partner’s Interests will be the pro rata share represented by his Interests of: 
 (a) 100%
of the sum of 
 (i) 65% of the unescalated (i.e., not increased by any interest rate or any other factor) value as of such
Valuation Date of the future net revenues attributable to the Partnership’s Proved Developed Producing Reserves, as estimated by the Independent Expert retained by the Managing Partner to prepare the most recent engineering report furnished to
the Investor Partners pursuant to Section 7.2(c); 
 (ii) 50% of the unescalated (i.e., not increased by any interest rate
or any other factor) value as of such Valuation Date of the future net revenues attributable to the Partnership’s Proved Developed Non-Producing Reserves, as estimated by the Independent Expert retained by the Managing Partner to prepare the
most recent engineering report furnished to the Investor Partners pursuant to Section 7.2(c); 
 provided that prior to the calculation of
the value of such future net revenues, that value (A) shall be adjusted by the Independent Expert to reflect the risks of production and development of such reserves and any other economic contingencies that would normally be considered by a
purchaser of Proved Reserves and (B) shall be discounted to present value at a rate equal to 10%; 

  
 39 

 MINUS 
 (b) the amount of all liabilities, indebtedness, expenses, and obligations of the Partnership as of the Valuation Date as shown on the Partnership’s most recent audited financial statements furnished
to the Investor Partners pursuant to Section 7.2(a) that were allocable as of the end of such fiscal year to the Investor Partners; and 
 (c) any distributions made to Investor Partners between the Valuation Date and the date of payment of the repurchase attributable to the Interests being repurchased shall be deducted from the repurchase
price. The effective date of any such sale for purposes of determining such deduction will be deemed to be the day on which payment of the repurchase price is transmitted. 
 Section 8.4 Notices of and Limitations on Right of Presentment. 
 (a)
Prior to May 31 of each year in which the Right of Presentment exists, the Managing Partner shall notify each Investor Partner requesting repurchase under Section 8.3 of the amount that will be paid to repurchase each Interest and the
method by which that repurchase price was calculated. Upon their receipt of such notification, the requesting Investor Partners who wish to present their Interests for repurchase shall do so by properly completing and executing the form of
assignment that will accompany the Managing Partner’s notification and returning it to the Managing Partner within 20 calendar days after the date of the notification. Such presentment by an Investor Partner shall constitute his acceptance of
the repurchase offer of the Managing Partner, subject to the terms of this Article 8. Payment for Interests presented for repurchase during a year will be made in cash not less than 60 nor more than 75 calendar days after receipt by the Managing
Partner of the assignments of the Interests so repurchased. 
 (b) The maximum number of Interests that the Managing Partner (or
an Affiliate thereof) shall be required to purchase during any calendar year in which the right to present Interests exists shall not exceed 5% of the total number of Interests outstanding at the beginning of such calendar year. 

(c) In addition to the limitation imposed by subsection (b) above, the obligation of the Managing Partner or Affiliates thereof, to
purchase Interests and to purchase interests in Affiliated Programs previously or subsequently organized by the Managing Partner or Affiliates thereof shall not exceed $500,000 in any calendar year, and such persons may elect not to purchase the
excess. If a greater number of Interests and interests in such previously or subsequently organized Affiliated Programs are presented for repurchase than are required to be accepted under this subsection (c), those Interests and interests will be
accepted for repurchase in the following manner: (i) all required repurchases will be allocated among the other affected partnerships (adjusted to reflect repurchases within the previous twelve months) pro rata based on their initial subscribed
capital, (ii) to the extent that the amount allocated to any partnership described in clause (i) exceeds the repurchase price of interests in that partnership presented for repurchase, such amount shall be allocated among the other of
those partnerships in the manner described in clause (i) until the entire $500,000 limitation (as adjusted) has been allocated, and (iii) interests in each partnership described in clause (i) shall be accepted for repurchase in
amounts equal to the portion of the $500,000 limitation allocated to each such partnership. 

  
 40 

 (d) In determining if the required number of the outstanding Interests pursuant to
subsection (c) above have been repurchased during any calendar year, all purchases by the Managing Partner or Affiliates thereof of Interests and interests in Affiliated Programs previously or subsequently organized by the Managing Partner or
Affiliates thereof, which purchases have been made at any time during the twelve-month period ending on the date on which such persons are to purchase Interests hereunder shall be included in the calculation of the Interests and other interests
repurchased. If a greater number of Interests are presented for repurchase than those persons are required to repurchase, the Interests to be repurchased will be selected by lot or by such other method as the Managing Partner deems reasonable.
Participation by Investor Partners in any such lottery shall be determined by calculating the proportion that the number of Interests presented for repurchase by each Investor Partner bears to the total number of Interests presented for repurchase
at that time. If any Interests presented for repurchase are not purchased, they will be returned to the record owners thereof and will be eligible for repurchase during succeeding years only if new repurchase requests are made and the Interests are
again presented for repurchase. Interests not repurchased in the year presented for repurchase will have no priority with respect to repurchase in subsequent years. 
 (e) If, prior to May 31 of the year in which the Right of Presentment exists, the price for either oil or gas received by the Partnership from its Program Wells decreases by 20% or more as compared
to the price being received as of the Valuation Date, the Managing Partner may, in its sole and absolute discretion, refuse to repurchase any Interests presented for repurchase. Further, if the Managing Partner or Affiliates thereof have purchased
the required number of Interests at any time during the twelve-month period ending on the date on which the Managing Partner is to purchase Interests from the Investor Partners pursuant to the Right of Presentment, the Managing Partner’s
obligation to purchase Interests is discharged. In such event, the Managing Partner shall notify the presenting Investor Partners of the Managing Partner’s election not to repurchase any of the Interests presented for repurchase and the basis
for such refusal and shall provide to any presenting Investor Partner who so requests access to such books and records of the Partnership as shall be reasonably necessary for such Investor Partner to verify the basis for such refusal. 

(f) For purposes of this Agreement, Interests repurchased and held by the Managing Partner or an Affiliate thereof shall continue to be
outstanding. 
 Section 8.5 Cessation of Right of Presentment. In the event the obligation of the Managing Partner
or any Affiliate thereof to repurchase Interests from Investor Partners pursuant to their Right of Presentment is determined by counsel to the Partnership to be in violation of any existing or future laws or to expose the Partnership or the Investor
Partners to material adverse federal income tax consequences, such obligation shall become null and void and of no further force or effect, but only to the extent necessary in the opinion of counsel to the Partnership to comply with such laws or to
avoid such consequences. 

  
 41 

 Section 8.6 Removal of Managing Partner. 

(a) A Majority in Interest of the Investor Partners shall have the right to remove the Managing Partner and to elect and substitute a new
Managing Partner. In such event, the removed Managing Partner shall be required to offer to sell a minimum of 20% of, and shall have the right to offer to sell up to the remaining 80% of, its interest in the Partnership to the new Managing Partner
at a price, Method of Payment (as determined pursuant to this section), and on such other terms and conditions as are mutually agreeable to the new Managing Partner. If after the new Managing Partner and the removed Managing Partner have agreed on
the amount of the removed Managing Partner’s Partnership interest that is to be sold to and purchased by the new Managing Partner (which agreement must be reached within 10 days of the removal of the Managing Partner), such parties are unable
to agree within 10 days on the purchase price of such interest, the new Managing Partner and the removed Managing Partner shall select a mutually agreeable Independent Expert to determine such purchase price. Such Independent Expert, in determining
such price, shall take into account appropriate discount factors in light of the risk of recovery of the oil and gas reserves attributable to the Partnership. The closing of the purchase of such Partnership interest shall take place at the office of
the removed Managing Partner within 15 days following the agreement upon or determination of the purchase price for the interest to be acquired by the new Managing Partner, or at such other time or place as the removed Managing Partner and the new
Managing Partner may agree upon in writing. In the event the new Managing Partner agrees to purchase less than all of the offered interest of the removed Managing Partner in the Partnership, the removed Managing Partner shall have the right to have
distributed to it in kind such Partnership assets and properties attributable to the Partnership interest not purchased by the new Managing Partner as it would have been entitled to receive if the Partnership were dissolved and terminated pursuant
to Section 9.4 at such time. The removed Managing Partner shall cause, to the extent legally possible, all of its contractual rights, obligations, and duties as Managing Partner of the Partnership to be assigned to the new Managing Partner, and
the new Managing Partner shall continue the business of the Partnership without the occurrence of any dissolution and shall accept all responsibilities of the removed Managing Partner and make arrangements satisfactory to the removed Managing
Partner to release it from and indemnify it against personal liability for any Partnership indebtedness and liabilities. This Agreement shall thereafter be duly amended to delete the removed Managing Partner and to name the new Managing Partner.
Each Investor Partner (and any person who hereafter becomes a substituted Investor Partner by his execution, adoption, or acceptance of this Agreement) hereby consents to the admission of the new Managing Partner as the substituted Managing Partner
and to the continuance of the business of the Partnership by such substituted Managing Partner, and authorizes such Managing Partner to certify on his behalf pursuant to the power of attorney granted in Section 10.2 such Investor Partner’s
consent to the admission of such new Managing Partner as the Managing Partner of the Partnership and to execute any amendments to this Agreement required for such purpose. If, under the laws of any jurisdiction to which the Partnership or this
Agreement is subject, the removal or withdrawal of the Managing Partner pursuant to this Section 8.6(a) results in the Partnership being dissolved, then the Partnership shall be deemed dissolved and reconstituted. Each Investor Partner (and any
person who hereafter becomes a substituted Investor Partner by his execution, adoption, or acceptance of this Agreement) hereby consents to the continuation or reconstitution of the Partnership pursuant to this Section 8.6(a) and authorizes the
substituted Managing Partner to certify on his behalf pursuant to the power of attorney granted in Section 10.2, such Investor Partner’s consent to the continuation or reconstitution of the Partnership and to execute any amendments to this
Agreement required for such purpose. 

  
 42 

 The “Method of Payment” by the new Managing Partner for the removed Managing
Partner’s interest must be fair and must protect the solvency and liquidity of the Partnership. Where the termination is voluntary, the method of payment will be deemed presumptively fair where it provides for a non-interest bearing unsecured
promissory note with principal payable, if at all, from distributions which the terminated Managing Partner otherwise would have received under the Partnership Agreement had the Managing Partner not been terminated. Where the termination is
involuntary, the method of payment will be deemed presumptively fair where it provides for an interest bearing promissory note coming due in no less than five years with equal installments each year. 

(b) The Partnership, acting in accordance with a vote or consent of a Majority in Interest of the Investor Partners, shall have the right
pursuant to Section 7 of the Program Agreement to remove MOC as Program Manager and substitute a successor to act in such capacity. 
 ARTICLE IX 
 DISSOLUTION, RECONSTITUTION, LIQUIDATION, AND TERMINATION

 Section 9.1 Dissolution. The Partnership shall be dissolved upon the occurrence of any of the following:

 (a) December 31, 2060; 
 (b) the vote at a duly held meeting or consent in writing of a Majority in Interest of the Investor Partners at any time; 
 (c) the sale, disposition, or termination of all or substantially all of the Leases then owned by the Partnership; 
 (d) the bankruptcy, insolvency, or dissolution (except dissolution as a consequence of merger, consolidation, recapitalization, or other reorganization effected in accordance with Section 8.2) of the
Managing Partner or the occurrence of any other event which would permit a trustee or receiver to acquire control of the property or affairs of the Managing Partner; provided that neither the Managing Partner’s filing of a voluntary petition or
answer seeking reorganization or similar relief under bankruptcy law, nor the Managing Partner’s reorganization or obtaining similar relief under such law shall cause the dissolution of the Partnership; 

(e) the adjudication of insolvency or bankruptcy of the Partnership, or an assignment by the Partnership for the benefit of creditors;

 (f) the withdrawal or retirement of the Managing Partner; or 

  
 43 

 (g) except as otherwise provided in this Section 9.1, the occurrence of any other event
which, under the laws of the State of Delaware, causes the dissolution of a limited partnership. 
 The death, retirement, insanity, legal
disability, insolvency, dissolution, or withdrawal of any Investor Partner will not result in the dissolution or termination of the Partnership, and, upon the occurrence of any such event, the estate, personal representative, guardian, or other
successor in interest of any such Investor Partner or the Investor Partner, as the case may be, (i) will continue to be liable for all of the debts and obligations of such Investor Partner pursuant to this Agreement, (ii) may become a
substituted Investor Partner only pursuant to the provisions of Section 8.1, (iii) may transfer the Partnership interest of such Investor Partner only pursuant to the provisions of Article VIII hereof, and (iv) will not have any right to
withdraw the Capital Contribution of such Investor Partner except as expressly set forth in Section 9.3 of this Agreement. 

Section 9.2 Covenant Not to Withdraw. Except as permitted by Section 9.3(c), each Partner covenants and agrees that it
shall not cause the dissolution of the Partnership by its voluntary withdrawal therefrom, either directly, by dissolution or by any other voluntary act, provided that the Managing Partner may withdraw upon the later to occur of (i) the
completion of a Partnership’s primary drilling activities under the Drilling Program and (ii) the fifth anniversary of the date that Investor Partners were admitted to the Partnership. In order to exercise its right of withdrawal, the
Managing Partner must give the Investor Partners at least 120 days’ advance written notice. In the event the Managing Partner assigns its interest in the Partnership to a person who becomes a substituted Managing Partner of the Partnership
pursuant to Section 8.2, the subsequent dissolution of the old Managing Partner shall not terminate the Partnership and shall not be deemed to constitute a breach or violation of the covenant contained in this Section 9.2. 

Section 9.3 Reconstitution. 
 (a) In addition to the other rights and remedies the Investor Partners may have hereunder or otherwise, in the event the Managing Partner withdraws or retires from the Partnership (directly or as a result
of the events causing dissolution under Section 9.1(e)) and such withdrawal or retirement causes dissolution of the Partnership, a Majority in Interest of the Investor Partners, acting at a meeting of the Investor Partners to be held within 90
days following receipt of written notice of such event from the Managing Partner, shall be entitled to reconstitute the Partnership (the Partnership, as reconstituted, is referred to herein as the “Reconstituted Partnership”) and elect and
substitute a new Managing Partner (which may be the retiring Managing Partner). Such new Managing Partner shall be entitled to acquire the Partnership interest of the retiring Managing Partner on the same basis and in the same manner as is set forth
in Section 8.6. In connection with such acquisition the actions described in Section 8.6 shall be taken by the new Managing Partner and the retiring Managing Partner, and each Investor Partner (and any person who hereafter becomes a
substituted Investor Partner by his execution, adoption, or acceptance of this Agreement) hereby consents to the admission of such new Managing Partner as a substituted Managing Partner of the Partnership in the same manner, and with the same
effect, as consent is provided by the Investor Partners in Section 8.6. The retiring Managing Partner will pay all expenses concerning the valuation of its Partnership Interest and expenses associated with transferring management control
incurred as a result of its withdrawal or retirement from the Partnership. 

  
 44 

 (b) In the event a Majority in Interest but less than all of the Investor Partners elect to
reconstitute the Partnership pursuant to this Section 9.3, the Partners’ capital accounts shall be adjusted by (i) assuming the sale of all assets of the Partnership for cash at their respective fair market values (as determined by an
appraiser selected by the new Managing Partner) and the payment of all Partnership debts and liabilities as of the date of the reconstitution of the Partnership and (ii) debiting or crediting each such capital account (other than the new
Managing Partner’s capital account, but including the retiring Managing Partner’s capital account (to the extent that the retiring Managing Partner’s Partnership interest was not purchased by the new Managing Partner pursuant to
subsection (a) above)) with its respective share of the hypothetical gains or losses resulting from such assumed sales and the hypothetical deductions or losses, if any, resulting from the assumed payment of such debts and liabilities in the
same manner as such capital account would be debited or credited on the actual sales of such assets and the actual payment of such debts and liabilities. 
 The new Managing Partner shall then sell for cash an amount of Partnership oil and gas properties having a fair market value (as determined by such appraiser) equal to the fair market value (so
determined) of all Partnership oil and gas properties times the ratio of the aggregate of the positive capital account balances, as so adjusted, of the Investor Partners that have not elected to reconstitute the Partnership and the retiring Managing
Partner (to the extent that the retiring Managing Partner’s Partnership interest was not purchased by the new Managing Partner pursuant to subsection (a) above) to the positive capital account balances, as so adjusted, of all Partners. The
new Managing Partner shall then distribute such cash to the Investor Partners that have elected not to reconstitute the Partnership and to the Managing Partner (to the extent provided above) in proportion to the positive balances of their respective
capital accounts, as so adjusted. Such distribution shall take place by the later of (i) the end of the Partnership taxable year in which the reconstitution occurs or (ii) 90 days after the date of such reconstitution. Neither the retiring
Managing Partner nor any Investor Partner that has elected not to reconstitute the Partnership shall be liable to the Partnership or any other Partner for the amount of any deficit balance in his or its capital account after a distribution in
liquidation of his or its interest in the Partnership. 
 Notwithstanding the foregoing, the retiring Managing Partner shall
have the right to elect to receive a distribution in kind of oil and gas properties having a fair market value (as determined by such appraiser) equal to the fair market value (so determined) of all Partnership oil and gas properties times the ratio
of the positive balance in its capital account, adjusted as provided above, to the positive capital account balances, as so adjusted, of all Partners, subject to an obligation to become a party to the Program Agreement and any operating agreements
to which such properties are subject. Any interest in Partnership properties distributed to the retiring Managing Partner shall be subject to such liens, encumbrances, and restrictions as affect the properties on the date of such distribution and
will be subject to and operated in accordance with the operating agreements then in effect. 

  
 45 

 All gain, loss, and amounts realized on the sale of Partnership oil and gas properties by
the new Managing Partner to provide cash for distribution to such Investor Partners and to the retiring Managing Partner shall be allocated to such Investor Partners and the retiring Managing Partner in the same proportions as the proceeds of such
sale are distributed; provided that if the retiring Managing Partner or any Investor Partner elects to receive a distribution of Partnership properties in kind, all gain, loss, and amounts realized on such sales shall be allocated solely to the
Partners receiving cash in the same proportions as the proceeds of such sale are distributed. 
 The new Managing Partner, on
behalf of the Investor Partners that have elected to form the Reconstituted Partnership, shall retain for the benefit of the Reconstituted Partnership all oil and gas properties of the Partnership remaining after the distribution provided for above,
and all other Partnership assets, and the Reconstituted Partnership shall assume all debts and liabilities of the Partnership. The Partnership oil and gas properties retained by the Reconstituted Partnership shall be subject to such liens,
encumbrances, and restrictions as affect such properties on the date of the reconstitution of the Partnership and will be subject to and operated in accordance with the operating agreements then in effect. If the amount of property as of the date of
the reconstitution of the Partnership is not sufficient to satisfy the positive balances in all of the Partners’ capital accounts, as so adjusted, Partnership property shall be sold (or distributed) and retained by the new Managing Partner in
the manner described above in proportion to the positive balances of the Partners’ respective capital accounts. 
 (c) In
the event an Investor Partner withdraws from the Partnership, the remaining Investor Partners hereby agree that the Partnership is to be reconstituted immediately. The remaining Investor Partners hereby authorize the Managing Partner to take such
action as the Managing Partner deems necessary or appropriate to effect such reconstitution and to continue the business of the Partnership without interruption, including use by the Managing Partner of the power of attorney granted by each
remaining Investor Partner pursuant to Section 10.2 to execute on behalf of each such remaining Investor Partner any amendments to this Agreement required for such purpose. The withdrawing Investor Partner will pay all expenses incurred as a
result of his withdrawal from the Partnership. The withdrawing General Partner shall remain subject as a General Partner with respect to any liabilities or obligations of the Partnership arising prior to such withdrawal. Upon withdrawal from the
Partnership, a General Partner is entitled to continue to receive any distributions to which he is otherwise entitled under this Agreement for the period prior to his withdrawal; however, such General Partner shall not be entitled to receive the
fair value of his interest in the Partnership as of the date of such withdrawal based upon his right to share in distributions from the Partnership, and neither the Partnership nor the Managing Partner has any obligation to repurchase any interest
in the Partnership from the withdrawing General Partner. The withdrawing General Partner will no longer be entitled to receive any distributions nor shall such General Partner have any rights as an Investor Partner under this Agreement. The Sharing
Ratios will be recalculated among the Investor Partners without regard to the withdrawing General Partner’s Capital Contribution. 
 (d) In the event the Partnership is reconstituted pursuant to subsection (c), the Partners’ capital accounts shall be adjusted by (i) assuming the sale of all assets of the Partnership for cash
at their respective fair market values (as determined by the Managing Partner or an appraiser selected by the Managing Partner) and the payment of all Partnership debts and liabilities as of the date of the reconstitution of the Partnership and
(ii) debiting or crediting each such capital account with its respective share of the hypothetical gains or losses resulting from such assumed sales and the hypothetical deductions or losses, if any, resulting from the assumed payment of such
debts and liabilities in the same manner as such capital account would be debited or credited on the actual sales of such assets and the actual payment of such debts and liabilities. 

  
 46 

 (e) The distribution of cash or property to the Investor Partners that have elected not to
reconstitute the Partnership in accordance with the provisions of this Section 9.3 shall constitute a complete return to each such Investor Partner of his Capital Contributions, to which each Investor Partner (and any person who hereafter
becomes a substituted Investor Partner by his execution, adoption or acceptance of this Agreement) hereby consents, and a complete distribution to such Investor Partner of his interest in the Partnership and all Partnership property, and no such
Investor Partner shall have any recourse against the new or the retiring Managing Partner, the Reconstituted Partnership or any other Investor Partner if the cash or property so distributed or received shall be insufficient to return in full his
Capital Contributions. 
 (f) In the event of the bankruptcy of a General Partner which pursuant to the Delaware Act results in
the dissolution of the Partnership, each of the remaining Partners hereby agrees that the Partnership shall be reconstituted immediately, and authorizes the Managing Partner to take the actions described in subsection (c) above. The trustee,
receiver, or other successor in interest of the bankrupt General Partner (i) will continue to be liable for all of the debts and obligations of such General Partner pursuant to this Agreement, (ii) may become a substituted General Partner
only pursuant to the provisions of Section 8.1, (iii) may transfer the Partnership interest of such General Partner only pursuant to the provisions of Article VIII hereof, and (iv) will not have any right to withdraw the Capital
Contribution of such General Partner except as expressly set forth in Section 9.4 of this Agreement. 
 Section 9.4
Liquidation and Termination. Upon dissolution of the Partnership (unless it is reconstituted in accordance with Section 9.3), no further business shall be conducted except for the taking of such action as shall be necessary for the
winding up of the affairs of the Partnership and the distribution of its assets to the Partners. The Managing Partner shall act as liquidator or may appoint in writing one or more liquidators who shall have full authority to wind up the affairs of
the Partnership and make final distribution as provided herein; provided, however, that, if the Managing Partner is not able to serve as liquidator and does not appoint a liquidator within a reasonable time after dissolution, the liquidator shall be
a person selected in writing by a Majority in Interest of the Investor Partners. The liquidator shall proceed diligently to wind up the affairs of the Partnership and make final distribution as provided herein. Until final distribution, the
liquidator shall continue to operate the Partnership properties with all of the power and authority of the Managing Partner. The liquidator is hereby authorized to take the following action without the further consent or joinder of any Partner:

 (a) As promptly as possible after dissolution and again after completion of the liquidation and termination of the
Partnership, the liquidator shall cause a proper accounting to be made of the Partnership’s assets, liabilities, and operations through the last day of the month in which the dissolution or termination occurs. 

  
 47 

 (b) The liquidator shall pay all of the debts and liabilities of the Partnership (including
all expenses incurred in liquidation) or otherwise make adequate provision therefor (including but not limited to the establishment of a cash escrow fund for contingent liabilities in such amount and for such term as the liquidator may determine).
To the extent cash required for this purpose is not otherwise available, the liquidator may sell assets of the Partnership for cash. 
 (c) After making payment or provision for all debts and liabilities of the Partnership, the liquidator shall sell all properties and assets of the Partnership for cash as promptly as is consistent with
obtaining the best price therefor. All gain, loss and amount realized on such sales shall be allocated to the Partners as provided in this Agreement, and the capital accounts of the Partners shall be adjusted accordingly. The liquidator shall then
distribute the proceeds of such sales to the Partners to satisfy any positive balances in their capital accounts, as so adjusted. 
 (d) Notwithstanding Section 9.4(c), in the event of a dissolution and liquidation of the Partnership pursuant to an exchange or tender offer, the liquidator may, after making provision for all debts
and liabilities of the Partnership, first adjust the capital account of each Partner by (i) assuming the sale of all remaining assets of the Partnership for cash at their respective fair market values (as determined by the liquidator in a
manner consistent with the terms of such exchange or tender offer) as of the date of the dissolution of the Partnership and (ii) debiting or crediting each such capital account with such Partner’s respective share of the hypothetical gains
or losses resulting from such assumed sales in the same manner as such capital account would be debited or credited on the actual sales of such assets. If such exchange or tender offer is conducted pursuant to a disposition of all or substantially
all of the assets of the Partnership or is otherwise binding on the Partners, the liquidator shall distribute all securities or other assets received from the disposition of the Partnership assets to the Partners proportionately based on the
Partners’ positive capital account balances, as so adjusted. 
 In the event of an exchange or tender offer that is not
binding upon all Partners, the liquidator shall then exchange for securities offered in the exchange or tender offer oil and gas properties having a fair market value (as determined by the liquidator as provided above) equal to the sum of the
positive balances in the capital accounts, as so adjusted, of the Partners who elect to accept the exchange or tender offer. The liquidator shall then distribute such securities to such accepting Partners on a basis reflecting the Partners’
respective positive balances, as so adjusted. The Managing Partner shall have, with respect to its Interests, the right to elect to receive a distribution in kind of Partnership oil and gas properties having a fair market value (as determined by the
liquidator as provided above) equal to the positive balance in its capital account, adjusted as provided above. The liquidator shall then sell the remaining property and distribute to the Investor Partners who elect not to accept the exchange or
tender offer all remaining cash in amounts proportionate to any positive balances in such Partners’ capital accounts, as so adjusted. All gain, loss and amount realized on the sale of Partnership oil and gas properties by the liquidator to
provide cash for distribution to such Investor Partners shall be allocated to such Investor Partners in the same proportions as the proceeds of such sale are distributed. 
 (e) Any distributions to the Partners in liquidation of the Partnership shall be made by the later of (i) the end of the taxable year in which the liquidation (as such term is defined in Treasury
Regulation 1.704-1(b)(2)(ii)(g)) occurs, or (ii) 90 days after the date of such liquidation. No Partner with a deficit balance in his or its capital account after such distribution shall be liable to the Partnership or any other Partner for the
amount of such deficit balance. 

  
 48 

 (f) Notwithstanding the foregoing, if upon dissolution of the Partnership any Partner shall
be indebted to the Partnership as a result of the failure to make a Capital Contribution required under this Agreement or otherwise, the liquidator shall retain such Partner’s share of cash or property that would otherwise be distributed and
apply such cash or property and the income therefrom to the liquidation of such indebtedness and the cost of the operation of such assets during the period of such liquidation; provided, if the amount of such indebtedness has not been liquidated
pursuant to the above procedure or otherwise paid by such Partner within six months of the dissolution of the Partnership, the liquidator may sell all or any portion of such property at a public or private sale for what is in the sole judgment of
the liquidator the best price obtainable. The proceeds of such sale shall be applied to the liquidation of the indebtedness then owing by such Partner, and the balance of such proceeds, if any, shall be distributed to such Partner. 

(g) The liquidator shall comply with any requirements of the Delaware Act and all other applicable laws pertaining to the winding up of
the affairs of the Partnership and the final distribution of its assets. The distribution of cash or property to the Partners in accordance with the provisions of this Section 9.4 shall constitute a complete return to the Partners of their
Capital Contributions and a complete distribution to the Partners of their interests in the Partnership and all Partnership property, and no Partner shall have any recourse against the Managing Partner or any other Partner if the cash so distributed
shall be insufficient to return in full his Capital Contributions.

Section 11.6 No Waiver. The failure of any Partner to insist upon strict performance of a covenant hereunder or of any

default in the performance of any obligation hereunder shall constitute a consent or waiver to or of any other breach or default in the performance of the same or any other obligation hereunder. 

Section 11.7 Evidence of Interest. At the sole option of the Managing Partner, an Interest may be evidenced by a certificate
in a form approved by the Managing Partner. The Managing Partner shall not be required to issue any such certificates, and, if such certificates are issued to any Investor Partner, the Managing Partner shall not be required to issue similar

NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained, the parties hereto do hereby agree as follows:

 Section 2. Acquisition of Interests in Prospects. 
 (a) Prospects Subject to
this Agreement. Subject to the terms and conditions hereof, the Participants shall acquire undivided interests in Leases within Prospects selected by the Program Manager in its sole discretion from time to time. At the time any Lease within a
Prospect is acquired, the Program Manager shall designate the area comprising the Prospect in the manner provided in the definition of such term (if the Prospect has not been previously so designated). Prospects may be limited to certain stated
depths and may include areas in which Leases may or may not have been acquired. The Program Manager shall maintain records showing the Prospects (and depths if limited by depth) so designated. In the case of certain Prospects, the designation of
Prospects may conform generally to the geographic limits of individual Leases. In some cases, where known reservoirs cover large geographic areas and subsequent drilling does not depend directly on results obtained by the Program Wells, Prospects
may be directly adjacent or in close proximity to other Prospects. Leases on lands which are contiguous or in the vicinity of each other may constitute more than one Prospect, and a zone or horizon under an area may constitute a Prospect separate
and apart from another zone or horizon which lies in whole or in part under the same area. With respect to any Prospect that is not limited to a particular zone or horizon and which is in any large continuous known stratigraphic trend or formation
which could be defined as a continuous reservoir, the Program Manager may reduce the areal extent included in such Prospect to that area which covers the spacing unit or proration unit prescribed by the appropriate regulatory authority on such
Prospect or permitted by local practice, whichever is applicable, and such additional area, if any, as the Program Manager determines reasonable. A Prospect which is limited to a particular zone or horizon may be limited to that area which covers
the spacing unit or proration unit prescribed by the appropriate regulatory authority on such Prospect or permitted by local practice, whichever is applicable, to protect against drainage from adjacent wells if the well to be drilled by the Program
is to a horizon containing Proved Reserves. The area of a Prospect may be enlarged or contracted from time to time by the Program Manager in the reasonable exercise of its judgment. 

  
 6 

 The amount of the undivided interest in Leases to be assigned to the Participants by the
Program Manager shall be determined solely by the Program Manager and the Managing Partner of the Partnership, taking into account the nature of the risks associated with the drilling of wells on such Leases, the estimated costs of such drilling,
the amount of funds available from the Partnership for such drilling and such other factors as the Program Manager and the Managing Partner shall in good faith determine. The Program shall have no right to acquire the entire interest in any such
Lease, and the Program Manager and Affiliates thereof shall have the right to acquire or retain a portion of such interest in their own name, for their own account, or for the account of others. Any such interest so acquired or retained by the
Program Manager or such Affiliate shall be held independently and not as a part of the Program and shall not be subject to the terms and provisions of this Agreement. 
 The undivided interests in all Leases acquired by the Program shall be acquired and held by the Program Manager for the benefit of the Participants hereto as follows: the Partnership 60% and MD 40%.
Following commencement of production from a Program Well, the Program Manager shall assign and convey to the Partnership and MD the above-described undivided interests in the Leases proportionally reduced as to the interest acquired by the Program
insofar as such Leases pertain to the spacing or proration unit prescribed by regulatory authority for such productive Program Well. 
 (b) Sales of Leases to the Program. Any sale, transfer, or conveyance of a Lease to the Program by the Managing Partner or any Affiliate thereof, including an Affiliated Program, shall be subject to the
restrictions contained in Section 5.10(h) of the Partnership Agreement. 
 (c) Acquisition Price. The price to be paid by
the Participants with respect to their acquisition of an interest in a Lease pursuant to this Section 2 shall be an amount equal to the Participants’ respective shares, as set forth in Section 3(a) of either (i) the Lease
Acquisition Costs with respect to such Lease or (ii) as provided in Section 5.10(h) of the Partnership Agreement, the fair market value of such Lease. 
 (d) Conveyance. With respect to the Leases within Prospects that are acquired by the Participants hereunder, the interests in such Leases so acquired shall cover all depths and horizons designated by the
Program Manager as comprising such Prospect and as contemplated in Section 2(a) such interests shall be assigned, conveyed and transferred by the Program Manager or an Affiliate thereof pursuant to a special warranty deed. Further, any such
assignment by the Program Manager or an Affiliate thereof shall be made with full substitution and subrogation in and to all rights and actions of warranty which the Program Manager or such Affiliate may have against all former owners. 

  
 7 

 (e) Assignments of Record. Following commencement of production from a Program Well, as
contemplated in Section 2(a) the Program Manager shall cause record title to the Participants’ respective interests in such Program Well to be placed in the names of MD and the Partnership (or its designated nominee), except (i) where
record title is held in the name of a third party (as in the case where pursuant to industry practice record title is held by a third party, such as a pooled operating interest), in which event the Program Manager shall place of record MD’s and
the Partnership’s interests promptly following the receipt by the Program Manager or an Affiliate thereof of an assignment from such third party, (ii) in the case of a federal, state, or other Lease where an approval to the transfer is
required, in which event the Program Manager shall take steps to obtain approval from appropriate authorities of the assignment of MD’s and the Partnership’s interests in any such Lease as promptly as possible following the time that such
assignment is to be made hereunder (iii) in the case where delays in the recording of assignments occur because of the practices of the recording office or officers, (iv) in the case of Indian or other Leases where the royalty interest or
other term of any such Lease is required to be renegotiated as a condition to the lessor’s consent to the assignment of MD’s and the Partnership’s interests, in which event MD’s and the Partnership’s interests in such Lease
shall be held in the name of the Program Manager as nominee for MD and the Partnership so long as any such arrangement does not jeopardize the validity or substance of such Lease or subject it to forfeiture or other penalty, or (v) where the
interests in the Lease to be assigned to MD and the Partnership cannot be exactly determined because of pooling or unitization laws, rules or regulations or agreements, the rights of third parties under area of mutual interest or other agreements,
or other similar circumstances, in which event the Program Manager shall promptly proceed to determine such interests and shall place them of record as promptly as possible. 
 (f) Title Examination. Prior to drilling a Program Well on a Prospect, the Program Manager shall cause to be done or be satisfied that there has been done such title examination and other title curative
work as the Program Manager, in its sole discretion, shall determine to be necessary or appropriate in accordance with general industry standards. 
 Section 3. Allocation of Costs. The costs of activities and operations conducted pursuant to this Agreement shall be allocated to and paid by the parties hereto as follows: 

(a) Organization and Offering Expenses. All Organization and Offering Expenses attributable to the Partnership shall be allocated to and
paid by MD and MD shall receive a contribution credit in respect of such Organization and Offering Expenses equal to 1.5% of the subscriptions to the Partnership made by the Partners. 

(b) Sales Commissions and Marketing Fees. An amount equal to all Sales Commissions and Marketing Fees shall be deducted from the proceeds
realized from the sale of interests in the Partnership and will not be available to the Partnership for the Partnership’s operations. 
 (c) Lease Acquisition Costs. MD shall contribute or cause to be contributed to the Program all Leases to be acquired by the Program and shall receive a contribution credit in respect of the contributed
Leases equal to the acquisition costs of the contributed Leases (which shall be determined in accordance with Section 2(c)) to the extent that such costs do not exceed 16.15% of the subscriptions by Partners to the Partnership. To the extent
that such costs exceed 16.15% of the subscriptions by investor partners to the Partnership, then such excess costs shall be allocated 25% to MD and 75% to the Partnership and capital contributions of the Partners to the Partnership shall be used to
reimburse MD for 75% of such excess. 
 (d) Intangible Drilling Costs. All Intangible Drilling Costs shall be allocated entirely
to the Partnership. 

  
 8 

 (e) Tangible Costs. All Tangible Costs shall be allocated entirely to the Partnership;
provided, however, that to the extent, if any, that the total costs allocated to MD pursuant to paragraphs (a) and (c) above are less than an amount equal to 17.65% of the subscriptions by Partners to the Partnership (“Deficit
Amount”), then MD shall be allocated an amount of Tangible Costs equal to the Deficit Amount. 
 (f) Operating Costs and
Reporting and Legal Expenses. All Operating Costs and Reporting and Legal Expenses incurred with respect to Program Wells shall be allocated 25% to MD and 75% to the Partnership. 

(g) Administrative Costs. All Administrative Costs incurred by the Program Manager or any of its Affiliates in managing and conducting
the business and affairs of the Partnership or the Program, including expenses incurred in providing or obtaining such professional, technical, administrative and other services and advice as the Program Manager may deem necessary or desirable shall
be allocated 25% to MD and 75% to the Partnership and shall be reimbursed by the Participants pursuant to Section 8. 
 (h)
Management Fee. In consideration for services to be rendered by MD in managing the business of the Partnership, the Program during each of the initial three years of the Partnership will pay to MD the Management Fee. The Management Fee will be
allocated 25% to MD and 75% to the Partnership. The portion of the Management Fee during a particular Partnership year allocated to the Partners will be paid by the Program in monthly or other periodic installments from funds which would otherwise
be available for distribution to the Partners during such Partnership year. To the extent that the Partnership has insufficient distributable funds during a particular Partnership year to fully pay its share of the Management Fee payable during the
Partnership year, then the amount of such unpaid Management Fee will be carried forward and payable in the next succeeding Partnership year. 
 (i) Other Costs. All other costs (including the Gas Marketing Fee) incurred shall be allocated 25% to MD and 75% to the Partnership. 

(j) The above costs that constitute Direct Costs shall be billed directly to and paid by the Program to the extent practicable.

 Section 4. Allocation of Revenues. Except as provided in Attachment A attached hereto, all revenues attributable to
the activities and operations conducted pursuant to this Agreement shall be allocated to and received by the parties hereto as follows: 
 (a) Revenues from Program Operations. Subject to subparagraph (b) below, all revenues from Program operations, including without limitation, all revenues directly or indirectly resulting from the
investment of revenues from Program operations, shall be allocated 25% to MD and 75% to the Partnership. 
 (b) Revenues from
Disposition of Program Assets. 

  
 9 

 (i) Revenues resulting from the sale or other taxable disposition of an oil
and gas property (as such term is defined in Section 614 of the Code) shall be allocated, (A) to the extent such revenues constitute a recovery of the Program’s simulated tax basis in such property, to the parties in the same
percentages as the simulated tax basis of the property sold was allocated up to an amount equal to the Program’s simulated tax basis in such property at the time of such sale, and (B) thereafter, to the parties in a manner which will cause
the aggregate of all revenues allocated to the parties from such sale or disposition and from all prior sales (to the extent possible) to equal the amounts which would have been allocated to the parties if all such revenues had been allocated 25% to
MD and 75% to the Partnership. For purposes of computing the simulated tax basis of any such property, depletion deductions shall be computed as provided in paragraph 4(c) of Attachment A without regard to depletion deductions actually
claimed by the parties under paragraph 6(d) of Attachment A. 
 (ii) All revenues resulting from the
rental, sale or other disposition of any item of depreciable property shall be allocated (A) to the extent such revenues constitute a recovery of the Program’s adjusted tax basis in such property, to the parties in the same percentages as
the adjusted tax basis of the property sold was allocated up to an amount equal to the Program’s adjusted tax basis in such property at the time of such sale, and (B) thereafter, to the parties in a manner which will cause the aggregate of
all revenues allocated to the parties from such rental, sale or other disposition and from all prior rentals or sales (to the extent possible) to equal the amounts which would have been allocated to the parties if all such revenues had been
allocated 25% to MD and 75% to the Partnership. 
 (iii) All revenues resulting from the disposition of any other
property shall be allocated 25% to MD and 75% to the Partnership. 
 (iv) All dry hole and bottom hole and
similar contributions shall not be considered to be revenues hereunder but shall be applied to reduce the Intangible Drilling Costs of the respective Program Wells to which they relate. 

Section 5. Ownership of Production. 
 Each Participant shall have the right to take in kind or separately dispose of its proportionate share of all oil and gas produced from any Lease subject to the Program pursuant to the terms of this
Agreement. Any extra expenditure incurred in the taking in kind or separate disposition by any party hereto of its proportionate share of production shall be borne by such party. Each party shall execute such division orders and contracts as may be
necessary for the sale of its interest in production from any such Lease. The proceeds from the sale of all production produced, saved, and sold from any Prospect herein shall be paid to MOC by all purchasing companies purchasing such production,
and by the execution of this Agreement, MOC and the Participants covenant and agree to hold harmless all purchasing companies from any and all liability by reason of paying any such proceeds to MOC. Further, the Participants authorize and direct MOC
to deduct from their proportionate share of such proceeds from such sales all Operating Costs and other expenses and costs of all types owed to MOC provided for under the terms of this Agreement and remit the balance from the sale to the
Participants. In the event any party shall fail to make the arrangements necessary to take in kind or separately dispose of its proportionate share of oil and gas produced from any such Lease, the Program Manager shall have the right, but not the
obligation, subject to the revocation at will by the party owning such production, to purchase such oil and gas or sell it to others at any time and from time to time for the account of such party at a price competitive with the best price
obtainable in the area for such production. Any such purchase or sale by the Program Manager shall be subject to the right of the owner of the production to exercise at any time its right to take in kind, or separately dispose of, its share of all
oil and gas not previously delivered to a purchaser. Any purchase or sale by the Program Manager of any other party’s share of oil and gas shall be only for such reasonable periods of time as are consistent with the minimum needs of the
industry under the particular circumstances. 

  
 10 

 Section 6. Management of Program. 

(a) Program Affairs. The Participants hereby designate MOC as the Program Manager who shall have the full and exclusive power and
authority to manage, control and administer the business and affairs of the Program and the properties of the parties subject to this Agreement, except to the extent otherwise set forth herein and in the Partnership Agreement. 

(b) Well Operations. The Participants, hereby designate MOC, and MOC agrees to act, as operator with respect to the drilling, testing,
and any attempted completion and equipping and operating (or plugging and abandoning, if necessary) of any Program Well to be drilled or developed hereunder, except in those instances in which (i) the Leases on which such Program Well is to be
drilled is already subject to an existing operating agreement under which a third party (not MOC) has already been designated as operator, (ii) the requisite number of third parties being joint working interest owners in such Program Well
decline to approve MOC as operator or (iii) a good faith determination is made by MOC that it is not in the best interests of the Participants and of MOC for it to act as operator. In conducting operations on a Prospect, MOC may use its own
personnel (including consultants retained by MOC), properties and equipment and may subcontract with any other Affiliate of MOC to perform such operations. The charge to MD and the Partnership for the use of MOC’s personnel (including
consultants retained by MOC), properties and equipment, the basis of pricing materials purchased by MD and the Partnership from MOC or any Affiliate thereof and the basis of pricing materials purchased by MOC or any Affiliate thereof from MD and the
Partnership shall be as provided in the Operating Agreement, subject to the terms of the Partnership Agreement. 
 (c) Operating
Agreement. With respect to each Program Well for which MOC is to serve as operator as contemplated in Section 6(b), all operations relating to such Program Well, including without limitation, all costs and expenditures of drilling, testing,
completing, and equipping and operating such Program Well shall be conducted pursuant to an Operating Agreement between MOC as operator, and the Participants as non-operator. In the event, at the time of acquisition of a Lease by the Participants,
such Lease is subject to another operating agreement or if MOC enters into an operating agreement with third parties that are joint operating interest owners in such Program Well, nevertheless, the Operating Agreement between MOC and the
Participants shall govern operations as between them, provided that MOC and the Managing Partner shall have the right to amend the Operating Agreement between MOC and the Participants covering certain of the Leases to conform to such other operating
agreement (provided, the Operating Agreement may not be amended as provided above in any manner that the Managing Partner determines will adversely affect the Partnership or the Partners in any material respect) and MOC shall have the right to
charge the Joint Account under the Operating Agreement between MOC and the Participants a share attributable to the Participants’ interest of any costs or expenses incurred by MOC under such other operating agreement which are not otherwise
provided for herein or in the Operating Agreement between MOC and the Participants. To the extent that the terms of this Agreement and the terms of the Operating Agreement attached hereto conflict, this Agreement governs and takes precedence over
the Operating Agreement. 

  
 11 

 (d) Program Funds; Distributions. Funds held by the Program Manager on behalf of the
Program, subsequent to their allocation to the Program, shall not be commingled with funds of any other entity. If the Program Manager elects at any time to distribute funds derived from revenues from Program operations or the disposition of Program
assets to any of the Participants, the Program Manager shall be obligated at the same time to make distributions of funds from such sources to the other Participants. All such distributions shall be made to the Participants in the same percentages
as the Participants are allocated revenues of the Program pursuant to Section 4. At no time shall the Program or the Program Manager on behalf of the Program retain in its accounts funds required to be distributed to the Participants pursuant
to the preceding sentence. At least quarterly, any cash funds of the Program which the Program Manager reasonably determines are not needed for the payment of existing or anticipated Program obligations and expenditures shall be distributed to the
Participants. 
 (e) Access to Records. Each Participant and the Partners thereof shall have access during normal business hours
to all books and records relating to the business and operations of the Program as provided in the Operating Agreement, provided that the Program Manager may refuse for a reasonable time to grant any Participant or any Partner thereof access to such
books and records as the Program Manager (i) has agreed shall be kept confidential or (ii) has determined in good faith should be kept confidential considering the interests of the Program and the Participants. 

(f) Liability and Indemnification of Program Manager. 

(i) Neither the Program Manager nor its Affiliates shall have any liability to the Participants for any loss suffered by a
Participant that arises out of any action or inaction performed or omitted relating to its duties or obligations or services rendered or to be rendered pursuant to this Agreement or the Operating Agreement, if the Managing Partner in good faith has
determined, as of the time of the conduct or omission, that the Program Manager’s or its Affiliate’s course of conduct or omission was in the best interest of the Participants, that the Program Manager or such Affiliate was acting on
behalf of or performing services for the Participants, and that such conduct or omission did not constitute negligence or misconduct. Termination of any action, suit or proceeding will not create a presumption that the Managing Partner or its
Affiliate did not act in the best interest of the Partnership. 

  
 12 

 (ii) The Partnership shall indemnify the Program Manager and its Affiliates
against any losses, judgments, liabilities, expenses, and settlements sustained or incurred by the Program Manager or such Affiliates as a result of any threatened, pending or completed claim, action, suit, or proceeding, whether civil, criminal,
administrative, arbitrative, or investigative, any appeal in such claim, action, suit, or proceeding, and any inquiry or investigation that could lead to such a claim, action, suit, or proceeding and which in any such case relates or which otherwise
arises from or is attributable to (a) the fact that the Program Manager is serving in such capacity or in the capacity as the operator under the Operating Agreement or (b) any acts, omissions or operations performed or omitted by the
Program Manager or such Affiliate on behalf of the Program or the Partnership or which otherwise relates to the activities and business affairs of the Program or the Partnership; provided that the Managing Partner has determined in good faith, as of
the time of the conduct or omission, that the conduct or omission was in the best interest of the Partnership and that the conduct or omission did not constitute negligence or misconduct. Any such indemnity will be satisfied only out of the assets
of the Partnership and in no event will the Investor Partners be liable therefor. 
 (iii) The Program Manager,
acting on behalf of the Program, may purchase and maintain insurance on behalf of the Program Manager and its Affiliates against any liabilities asserted against or expenses incurred by the Program Manager or its Affiliates in connection with
Program activities; provided, however, that the Participants (other than MD) shall not incur the cost of that portion of such insurance, if any, which insures the Program Manager or its Affiliates against any liability with respect to which the
Program Manager or its Affiliates are denied indemnification under the provisions of this Agreement; provided, however, that nothing contained herein shall preclude the Program Manager from purchasing and paying for such types of insurance including
without limitation, extended coverage liability and casualty and workers’ compensation, as would be customary for any person owning comparable assets and engaged in a similar business, or from naming the Program Manager and its Affiliates as
additional insured parties thereunder, provided, that the naming of such additional insured parties does not add to premiums payable by the Program. 
 (iv) The termination of any claim, action, suit, or proceeding by judgment, order, settlement, conviction, or a plea of nolo contendere or its equivalent does not alone establish that a person seeking
indemnification under this Section 6(f) is disqualified. Any person who is determined to be not entitled to indemnification under this Section 6(f) may petition a court of competent jurisdiction for a determination that in view of all
facts and circumstances that such person is fairly and equitably entitled to indemnity and the Partnership shall provide such indemnity as may be determined proper by such court; provided, however, that the court has determined that such person has
met the standard set forth in Section 6(f)(ii) above. 
 (v) Legal fees and expenses and other costs
incurred as a result of a claim described in this Section 6(f) shall be paid by the Partnership from time to time in advance of the final disposition of such claim if: (a) the claim relates to the performance or non-performance of duties
or services by the Program Manager or its Affiliates rendered on behalf of the Program and the Participants, (b) the claim is initiated by a third party who is not an Investor Partner, or the claim is initiated by an Investor Partner and a
court of competent jurisdiction specifically approves such advancement, and (c) the Program Manager or its Affiliate undertakes to repay the advanced funds to the Partnership in the event it is later determined that the Program Manager or such
Affiliate is not entitled to indemnification under the provisions of this Section 6(f). 

  
 13 

 (vi) To the extent that the Program Manager or its Affiliates are successful
on the merits or otherwise in defense of any claim, action, suit, or proceeding referred to in this Section 6(f) or in defense of any claim, issue, or matter therein, the Partnership shall indemnify the Program Manager or its Affiliates,
against the expenses, including attorneys’ fees, actually incurred by the Program Manager or such Affiliate in connection therewith. 
 (vii) The indemnification provided by this Section 6(f) shall continue as to the Program Manager and its Affiliates in the event the Program Manager ceases to act in the capacity of manager of the
Program or as operator under the Operating Agreement with respect to events occurring prior to the time such Program Manager or its Affiliate ceased to act in such capacity and shall inure to the benefit of the successors and assigns of the Program
Manager and such Affiliates. 
 Section 7. Removal of the Program Manager. 

The Partnership shall have the right to remove MOC as Program Manager and to elect and substitute a successor to act in the capacity as
Program Manager; provided, the Partnership shall not have the right to remove MOC as Program Manager and to elect and substitute a successor to act in such capacity during the term that MD or any of its Affiliates serve in the capacity of Managing
Partner. 
 Section 8. Reimbursement of the Program Manager. 

As may be requested by the Program Manager from time to time, the Program Manager shall be reimbursed by the Participants for their
respective share of all General and Administrative Expenses and other costs and expenses incurred by the Program Manager or any of its Affiliates in managing and conducting the business and affairs of the Program, including expenses incurred in
providing or obtaining such professional, technical, administrative, and other services and advice as the Program Manager may deem necessary or desirable. Reimbursements of General and Administrative Expenses made by the Partnership as a Participant
hereunder shall be made in accordance with Section 5.9 of the Partnership Agreement, including without limitation, the provisions contained in Section 5.9 of the Partnership Agreement which limit the amount of such reimbursement.

 Section 9. Tax Partnership. 
 This Agreement and Attachment A attached hereto are not intended and shall not be construed to create a joint venture, mining or other partnership (general, limited, or otherwise) or association or
to render the parties hereto liable as partners. The parties expressly agree that no party hereto shall be responsible for the obligations of the other parties, each party being severally responsible only for its obligations arising hereunder and
liable only for its allocable share of the costs and expenses incurred hereunder. Each of the Participants hereby agrees that this Agreement creates a partnership for federal and state income tax purposes only, which tax partnership shall function
and exist as set forth in Attachment A attached hereto.

 Section 10. Sales of Interests by MD. 

Subject to paragraph 7 of Attachment A, MD shall have the right to sell or otherwise dispose of the ownership interests in
Leases held by it as part of the Program and subject to this Agreement without obtaining the consent of the Partnership. MOC, MD, and their Affiliates shall have the right to sell or otherwise dispose of the ownership interests in Leases held by
them for their own account outside the Program and not subject to this Agreement on terms more or less favorable to the party or parties acquiring such interests than those terms contained in this Agreement with respect to the acquisition of
interests in such Leases by the Partnership, and the Partnership shall not have any claim or right to any consideration or benefits derived therefrom. 
 Section 11. Assignment. 
 Except as otherwise provided herein, no party hereto
shall have the right to assign its rights or obligations under this Agreement without the express written consent of the other parties, except in the event of the following assignments: 

(a) A disposition by MD of all or any portion of its rights or obligations hereunder to one or more Affiliates of MD; 

(b) A disposition by MD or any Affiliate thereof of all or any part of its rights or obligations hereunder to one or more persons that
have as a result of a merger, consolidation, corporate reorganization, or other transaction acquired all or substantially all of the assets of MD and have assumed the obligations of MD hereunder; or 

(c) A disposition by MD or any Affiliate thereof of all or any portion of its rights or obligations hereunder after the cessation of
substantially all drilling activities of the Program. 
 Any assignment shall be subject to paragraph 7 of
Attachment A. Notwithstanding anything in this Agreement to the contrary, MD shall have the right at any time to mortgage, pledge, or encumber the oil and gas properties and interests of MD under or subject to this Agreement to secure any debts
or obligations of MD or its Affiliates (whether or not such debts or obligations are related to the Program). If MD receives a bona fide offer from an unrelated third party to purchase an interest in any Lease in which the Partnership has interests
pursuant to this Agreement, MD shall request the offeror to make a similar offer available to the Partnership. 

Section 12. Term and Amendment of Agreement. 
 (a) This Agreement shall terminate upon the occurrence of any of the following: (i) the dissolution of the Partnership, or (ii) upon the election of MD after the cessation of substantially all
drilling activities of the Program, provided, in the case of clause (ii), that MD shall have given at least 120 days’ notice to the Investor Partners of the Partnership prior to such termination. Upon the occurrence of any of the foregoing
events, the provisions of paragraph 9 of Attachment A shall be applicable and the Participants shall be subject to the terms of the Operating Agreement or such other operating agreements as may then be in effect. 

  
 15 

 (b) This Agreement and Attachment A may only be amended, modified or changed by a
writing duly executed by MD, and the Partnership; provided that, to the extent required under the terms of the Partnership Agreement, the Partnership shall execute or have executed on its behalf such a writing only if the amendment, modification, or
change shall have been approved or consented to by a Majority in Interest of the Investor Partners thereof, to the extent required by the Partnership Agreement, and, provided further, the consent of the Partnership shall not be required if MD
determines that the amendment, modification, or change is necessary or advisable to ensure that the Program Agreement conforms with any changes in or modifications to the Code or does not adversely affect in a material manner the Investor Partners
of the Partnership. 
 Section 13. Insurance. 
 The Program Manager or Affiliates thereof shall carry for the benefit of the Participants insurance coverage in such amounts, with provisions for such deductible amounts and for such purposes as are
customarily carried by the Program Manager or such Affiliates in its operations. To the extent practical, all of the Participants shall be added as additional co-insureds under such coverage. The Program Manager shall notify the Participants of any
adverse material change in the insurance coverage of the Program as soon as possible after learning of such change. If possible, such notice shall be given 30 days in advance of the change in insurance coverage. In the event that the insurance
coverage carried for the benefit of the Participants is materially reduced, the Program, as soon as reasonably possible to do so, will halt all drilling activity until such time as comparable replacement insurance coverage is obtained. 

Section 14. Partnership Agreement. 
 In the event of conflict between the provisions of this Agreement and the provisions of the Partnership Agreement, the provisions of the Partnership Agreement shall control unless otherwise expressly
provided herein. This Agreement is subject to the provisions of the Partnership Agreement in all respects and all matters provided for herein shall also be governed by the provisions of the Partnership Agreement. 

Section 15. Entire Agreement. 
 This Agreement, together with Attachment A attached hereto, constitutes the entire agreement among the parties hereto with respect to the subject matter hereof, and supersedes all previous oral and
written and all contemporaneous oral negotiations, commitments, writings and understandings. 
 Section 16. Headings.

 The headings of the various sections, subsections, and other subdivisions of this Agreement have been inserted for convenient
reference only and shall not be construed to enlarge, diminish, or otherwise change the express provisions hereof. 

Section 17. Governing Law. 
 This Agreement shall be governed by and construed in accordance with the laws of the State of Texas, except that any laws of such state regarding choice or conflicts of law shall not be applied if the
result would be the application of a procedural or substantive law of another state or other jurisdiction.

purposes, and references to this Agreement shall also include such Attachments unless the context in which such references are used shall otherwise require.

counterparts, each of which shall be deemed an original, and all of which together shall constitute one and the same instrument.
