Section 5.3 (Additional Lease Acquisition Costs), and (viii) cost overruns associated with any project or operation with respect to which the Limited Partner has previously agreed to make Capital
Contributions hereunder (Funded Cost Overruns). Each of the categories of expenditures described in clauses (i), (ii),(iii), (iv), (v), (vi), (vii), and
(viii) of this Section 3.3(a) may include such contingent amounts as the General Partner in good faith shall determine to be appropriate under the circumstances.

(b) Requests for additional Capital Contributions pursuant to this Section 3.3 shall be made by the General Partner and agreed to by the
Limited Partner separately with respect to each



---

operation or acquisition included in any given category of expenditures as specified in subsection (a) above. Requests pursuant to this
Section 3.3 shall not be made more often than quarterly each year unless approved by the Limited Partner (i) except for requests for Additional Lease Acquisition Costs or Funded Cost Overruns, (ii) except in the event the
request is attributable to a proposal from an unrelated third party, or (iii) unless an emergency or some other urgent need for funds exists outside of the reasonable control of the General Partner. Payments of any additional Capital
Contributions agreed to be made by the Limited Partner pursuant to this Section 3.3 shall be requested by the General Partner and made by the Limited Partner in the manner provided for in Section 3.5(f).

(c) Notice of any request for additional Capital Contributions made by the General Partner shall be made on the online reporting system selected by the
Limited Partner. With respect to Geophysical and Geological Costs, Well Costs, Well Plugging Costs, Excessive Reworking Costs, Producer or Injector Well Costs, or Facilities Construction Costs, each request shall cover all of the Capital Costs
intended to be incurred during the next three months (and with respect to any Partnership well or Enhanced Recovery Operation or facility, the costs estimated to be incurred in connection with such well or operation or facility). With respect to
Additional Lease Acquisition Costs, each request shall contain the information specified in Section 5.3. With respect to Funded Cost Overruns, each request shall cover the reasonably anticipated overruns associated with the subject
operation or project. Each such request shall set forth, in addition to any information requested by such online reporting system, (i) the date by which the Limited Partner must elect in writing to make the requested additional Capital
Contributions, which date shall not be less than 30 days from the date the General Partner mails or sends such request, unless a shorter period is provided to the General Partner under any applicable authority for expenditure submitted
by an operator other than the General Partner or an Affiliate, in which event such shorter period shall also be applicable to the election period of the Limited Partner (provided that in no event shall such shorter period be less than 15 days),
(ii) the purpose or purposes for which the proceeds of the requested additional Capital Contributions are to be used, (iii) a copy of the applicable authority for expenditure submitted in connection with the well or operation,
(iv) to the extent practicable, a summary of the pertinent geological data relating to each well or operation with respect to which the proceeds that are requested are to be expended and financial projections with respect to the expenditure of
such additional Capital Contributions and the revenue projected to be received therefrom, (v) with respect to any well or operation with respect to which the proceeds requested are to be expended, a statement as to whether or not the General
Partner recommends the Partnership participate therein, and (vi) a summary of the action that the General Partner anticipates it will take under Section 3.3(d) and any applicable operating agreement if the Limited Partner does not
elect to make such requested additional Capital Contributions. In connection with any request pertaining to an Enhanced Recovery Operation, the General Partner shall endeavor to confine such request to the extent possible in accordance with
generally accepted industry standards to those matters or items which should be conducted in conjunction with each other. Thereafter, the General Partner shall promptly furnish to the Limited Partner such additional information concerning the use
and application of the requested additional Capital Contributions as the Limited Partner shall reasonably request. In the event the Limited Partner does not elect to pay all of the categories of requested additional Capital Contributions (or
operations or acquisitions within a given category), it may elect to pay all of the Capital Contributions requested to be used for any of the remaining categories of costs designated in the General Partner's request as provided above (or, as to a
given category, the costs associated with any other operation or



---

acquisition within such category). The General Partner shall not use any Capital Contributions received from the Limited Partner pursuant to this
Section 3.3 and designated for payment of one category of costs to pay any other category of costs, except to the extent multiple categories of costs are included in the same approved additional Capital Contribution request, in which
case the total amount reflected in such request may be used to pay any of the category of costs included in that request.

(d) If the
Limited Partner declines to make any additional Capital Contributions requested by the General Partner or fails to give timely notice to the General Partner pursuant to a request for additional Capital Contributions made pursuant to
Section 3.3(a), the General Partner may elect to take any action specified in paragraphs (1) through (7) below with respect to each Lease, Partnership well, operation or project to which the request pertains, if
appropriate:

(1) With respect to the acquisition of Leases pursuant to Section 5.3, the General Partner or its
Affiliates may purchase or retain for its or their own account the Leases not acquired by the Partnership.

(2) The General
Partner may cause the Partnership (to the extent it can do so under any applicable operating agreement) to abandon the operation or project, in which event all costs (if any) thereafter incurred in abandoning the operation or project shall be borne
by the Partnership.

(3) The General Partner may cause the Partnership to sell, farm-out or otherwise dispose of the well or
Lease (or the applicable part thereof) to which such operation or project pertains to any person; provided, however, that no such sale, farm-out or other disposition may be made to the General Partner or any Affiliate thereof without the prior
written consent of the Limited Partner.

(4) In the event a well or Lease to which such proposed operation or project
pertains is subject to an operating agreement, the General Partner may cause the Partnership to elect not to participate in a proposed operation and to assume the status of a non-consenting party under such operating agreement; provided,
however, that neither the General Partner nor any of its Affiliates shall be permitted to pay or shall pay the Partnerships non-consenting share of costs or expenses or any part thereof with respect to such operation or project under such
operating agreement.

(5) The General Partner may (provided that it has recommended under Section 3.3(c) that
the Partnership participate in such proposed operation or project) pay the requested additional Capital Contributions the Limited Partner declined to pay, and the amount so paid by the General Partner with respect to such operation or project shall
be credited to a separate account, which separate account shall be charged and credited as follows:

(x) Subject to
subparagraph (y) of this Section 3.3(d)(5), all of the Limited Partners share of costs and expenses with respect to such operation or project shall be charged to such separate account, and such separate account shall be
credited with the Limited Partners share of revenues from such operation or project (after deducting all production, severance, excise and similar taxes relating



---

thereto). Until the total amount credited to such separate account equals the amount specified in subparagraph (y) of this
Section 3.3(d)(5) with respect to such operation or project, the General Partner shall be allocated all of the costs and expenses charged to such separate account, and the Limited Partner shall be deemed to have relinquished to the
General Partner, and the General Partner shall have allocated to it and be entitled to receive, all of the revenues credited to such separate account.

(y) If, as and when the total amount of revenues received by and credited and allocated to the General Partner under subparagraph (x) of this Section 3.3(d)(5) shall equal the sum of the
following to the extent they are appropriate:

a. 300% of the amount charged to such separate account for Capital Costs;
and

b. 100% of the amount charged to such separate account for Lease Operating and Production Costs;

no further amounts shall be charged or credited to such separate account, and the Limited Partners share of all revenues and costs and expenses
thereafter arising or accruing with respect to such operation or project shall be allocated, charged and credited to the Limited Partner.

(6) With respect to a request pertaining to Facilities Construction Costs, the General Partner shall take such action as shall be mutually agreed upon by the Partners.

(7) The General Partner may take such other actions as may be mutually agreed upon by the Partners.

Section 3.4. Reduced Capital Contributions of a Partner. In the event the Partnership or the General Partner properly retains a portion of
a Partners share of Partnership revenues in accordance with Section 4.4 for the purpose of paying any Acquisition Costs, Capital Costs, Hedge Costs, or Organization and Third Party Acquisition Costs allocated to such Partner
hereunder, the amount so retained and not distributed shall reduce pro tanto the amount of Capital Contributions such Partner is required to thereafter make for the purpose of paying such costs.

Section 3.5. Payments of Capital Contributions.

(a) The General Partner shall pay the Capital Contributions referenced in Section 3.1(a) and the Limited Partner shall pay the Capital Contributions referenced in Section 3.2(a) so that the
Partnership can comply with its obligations to pay the Performance Deposit in accordance with the terms of the Purchase Agreement and the Assignment Agreement.

(e) Except as otherwise provided in subsections (a), (b), (c), and (d) above, the Limited Partner shall pay its Capital Contributions monthly upon request by the General Partner
in such amounts as are required to pay its share of all costs and expenses properly allocated to it hereunder. The General Partner may request on a monthly basis additional payments of the Capital Contributions agreed to be made by the Limited
Partner for the Limited Partners share of (i) all costs and expenses estimated to have been and/or to be incurred by the Partnership during that calendar month except those for which advances have previously been made or for which payment
will be made from another source and (ii) those costs and expenses estimated to be incurred by the Partnership during the next succeeding calendar month. Each monthly request for payment shall be adjusted to the extent the Limited
Partners cumulative share of actual Partnership disbursements for the preceding calendar months costs and expenses is either greater or less than the amounts previously contributed by the Limited Partner for such purpose. Any request for
payment by the Limited Partner of Capital Contributions shall be in writing and shall set forth (1) the type, nature or items of Partnership costs or expenses for which such payment will be used by the Partnership, including a division of the
costs and expenses as contemplated in clauses (i) and (ii) of this Section 3.5(e) and the adjustment referred to in this Section 3.5(e), (2) the net amount of the Capital Contributions to be paid
by the Limited Partner, and (3) the date by which payment of such Capital Contributions shall be received, which shall not be less than five business days from the date the notice is received by the Limited Partner.

(f) Payments by the Limited Partner of its Capital Contributions shall be made by wire transfer of immediately available funds to the Partnerships

(g) Any additional
Capital Contributions agreed to be made by the Limited Partner pursuant to Section 3.3 may be requested only during the period commencing on the date they were originally requested by the General Partner under Section 3.3 and
ending three months thereafter with respect to Capital Contributions to be used to pay Acquisition Costs and six months thereafter with respect to Capital Contributions to be used to pay Capital Costs and shall only be requested for and expended on
the respective purposes for which they were agreed to be made.

Section 3.6. Non-Payment of Capital Contributions.

(a) Except as otherwise provided in the following sentence, the Partnership shall have the right to pursue the remedies described in
this Section 3.6 and any remedy existing at law or in equity for the collection of the unpaid amount of the Capital Contributions agreed to be made in Section 3.1 and Section 3.2 or hereafter agreed to be made in
accordance with Section 3.3, including the prosecution of a suit against a defaulting Partner. In the event of a default by the Limited Partner of its obligation to make Capital Contributions with respect to Hedge Costs, the



---

provisions of subsection (d) below and any guaranty of General Electric Capital Corporation under Section 5.7 shall be the exclusive
remedies of the Partnership and the General Partner.

(b) In the event that the Limited Partner fails or refuses to make when due its share
of Capital Contributions, the General Partner shall be entitled (but shall not be obligated) to make such Capital Contributions to the Partnership which the Limited Partner is obligated to make and the amount so advanced shall be treated as a loan
from the General Partner to the Limited Partner and shall bear interest from the date of such advance at a rate equal to the Agreed Rate. The General Partner shall notify the Limited Partner of any such advance and request payment by the Limited
Partner of the amount so advanced, together with interest thereon from the date of the advance. If the Limited Partner fails or refuses to pay to the General Partner the amount so advanced, together with interest thereon from the date of the
advance, and if such failure or refusal persists for a period of 30 days following notice from the General Partner to the Limited Partner, it shall be deemed an Event of Default) hereunder.

(c) Upon the occurrence of an Event of Default, the Partnership may retain any revenues otherwise distributable to the Limited Partner pursuant to this
Agreement in an amount equal to the amount the Limited Partner failed or refused to contribute as required pursuant to the terms of this Agreement, together with interest on such past-due amounts at a rate equal to the Agreed Rate. Any amount so
withheld shall be deemed, for all purposes of this Agreement, to have been distributed to the Limited Partner and, other than that portion of such amounts representing interest, be deemed to have been recontributed by the Limited Partner to the
capital of the Partnership for the purposes for which contributions were initially requested. To the extent that the General Partner has advanced funds to the Partnership as a result of the default of the Limited Partner, the General Partner shall
be entitled to be reimbursed and paid the amount of such advance plus interest at the Agreed Rate from the amounts so withheld from the Limited Partner. If any dispute as to whether an Event of Default existed is resolved in favor of the Limited
Partner, then the General Partner shall pay to the Partnership for distribution to the Limited Partner an amount equal to any amounts wrongly paid by the Limited Partner to the Partnership which should have instead been paid to the Partnership by
the General Partner, or any amounts distributed by the Partnership to the General Partner instead of the Limited Partner, in connection with such Event of Default together with interest thereon at a rate equal to the Agreed Rate, and all costs and
expenses of the Limited Partner in resolving such dispute, including all attorneys fees expended in connection therewith. The General Partner shall be free at any time also to proceed under this Section 3.6(c) in addition to any
other remedies hereunder or as provided by law.

(d) If a Partner (the Defaulting Partner) fails or
refuses to make Capital Contributions to the Partnership hereunder when due to pay its allocable share hereunder of Hedge Costs and the other Partner (the Contributing Partner) in the Defaulting Partners stead
makes such Capital Contributions to the Partnership, then the terms and provisions of this Section 3.6(d) shall be operative. Specifically, in the instance described above, the Contributing Partner may exercise either of the following
options:

(i) The Contributing Partner may treat the payment by it of the Defaulting Partners Capital Contributions as
a loan to the Defaulting Partner, which loan shall bear interest from the date the payment is made at a rate equal to the Agreed Rate. Further, as



---

between the Contributing Partner and the Defaulting Partner, the terms and provisions of Section 3.6(b) and Section 3.6(c) shall be
applicable, mutatis mutandis.

(ii) The Contributing Partner may treat the payment by it of the Defaulting
Partners Capital Contributions as Capital Contributions from the Contributing Partner, in which case the Contributing Partner shall be entitled to receive all of the distributions that would otherwise be paid to the Defaulting Partner
hereunder until that point in time at which the Contributing Partner has received from such distributions an amount equal to 300% of the amount of the Capital Contributions made by the Contributing Partner in the Defaulting Partners stead;
provided, however, that if this option is elected, the Defaulting Partners share of the Hedge Costs paid with such Capital Contributions, and any deductions or losses relating thereto for state or federal income tax purposes, shall be
allocated to the Contributing Partner; and provided further, that the Defaulting Partners share of Partnership revenues, and any income or gain relating thereto for state or federal income tax purposes, shall be allocated to the Contributing
Partner until the revenues so allocated equal the distributions to be made to the Contributing Partner under this paragraph (ii).

(iii) If the Contributing Partner borrows funds in order to make the payment required by the Defaulting Partner, the Contributing Partner may pledge its right to receive distributions under this
Section 3.6(d) which would have been made to the Defaulting Partner to secure such borrowings.

Section 3.7.
Interest on and Return of Capital Contributions.

(a) No interest shall accrue on any contributions to the capital of the
Partnership; however, all interest which accrues on Partnership funds shall be allocated and credited to the Partners in accordance with Section 4.2.

(b) No Partner shall have the right to withdraw or be repaid any capital contributed by such Partner except (a) as provided in Section 4.4(b), Section 10.2, and Section 10.3 or
(b) in the instance when the Partnership receives a return of cash funds under the Purchase Agreement due to a return of the Performance Deposit a post-closing adjustment to the Adjusted Purchase Price, as determined pursuant to the Purchase
Agreement (in which event the General Partner shall cause the Partnership to refund immediately to each of the Limited Partner and the General Partner its respective allocable share of such cash funds).

Section 3.8. Payments and Advances by General Partner. The General Partner shall have the right to pay any indebtedness or obligation
of the Partnership out of funds of the General Partner, and may bill the Partnership therefor. Further, if at any time the General Partner advances funds to or on behalf of the Partnership or the General Partner is required to pay any indebtedness
or obligation of the Partnership in excess of the Capital Contributions of the General Partner agreed to be made in this Article III, such advance or payment shall constitute a loan by the General Partner to the Partnership. If any such
advance or payment is outstanding for more than 30 days, such advance or payment shall bear interest from the date first made at a rate equal to the Agreed Rate. No such advance or payment by the General Partner shall be deemed to be a contribution
by the General Partner to the capital of the Partnership. Any loan made by the General Partner hereunder to pay any costs or expenses



---

allocated and charged to any Partner shall be repaid (with payments to be applied first to the payment of interest and then to the repayment of principal)
from the revenues that would otherwise be next distributed to such Partner hereunder.

ARTICLE IV

ALLOCATIONS AND DISTRIBUTIONS

Section 4.1. Allocation of Costs and Expenses. Except as provided in Section 3.3 and Section 3.6, all costs and expenses of the Partnership shall be allocated and charged to the Partners as
follows:

(a) All Catastrophe Costs incurred by the Partnership shall be allocated 100% to the General Partner.

(b) In the event the transactions contemplated by the Purchase Agreement are consummated, Organization and Third Party Acquisition Costs shall be
allocated two percent to the General Partner and 98% to the Limited Partner. In the event the transactions contemplated by the Purchase Agreement are not consummated, Organization and Third Party Acquisition Costs shall be allocated 100% to the
General Partner.

(c) Hedge Costs shall be allocated 100% to the Limited Partner.

(d) All other costs and expenses of the Partnership not specifically allocated above shall be allocated (i) to the General Partner in accordance
with its GP Sharing Percentage and (ii) to the Limited Partner in accordance with its LP Sharing Percentage.

Section 4.2.
Allocation of Revenues.

(a) Except as provided in Section 3.3 and Section 3.6, all revenues of the
Partnership (which shall not include Capital Contributions and loans to the Partnership) shall be allocated and credited to the Partners as follows:

(i) Insurance proceeds, to the extent not otherwise expended by the Partnership to preserve and protect Partnership property in the event of an accident or other occurrence or to pay Partnership liabilities or other
obligations arising from an accident or other occurrence, shall be allocated between the Partners in the same manner as the revenues from the sale of the property to which such insurance proceeds related would be allocated under this
Section 4.2.

(ii) All revenues used to repay any principal, interest or other amounts owing with respect to any
Partnership borrowings or indebtedness shall be allocated to the Partners in the same proportions as the costs and expenses paid with such borrowings or indebtedness were allocated to the Partners (and, with respect to any indebtedness to which any
property acquired by the Partnership is subject at the time of its acquisition, in the same proportions as costs are allocated under Section 4.1(b) at the time such property is acquired by the Partnership).

(iii) After making the allocation provided for in Section 4.2(a)(ii) and taking into account the revenues allocated therein,
all additional revenues resulting from the sale



---

or other disposition of Depletable Property (as defined in Section 4.3(b)) shall be allocated to the Partners in the same percentages as the
costs of the property sold were allocated, to the extent such revenues constitute a recovery of Simulated Basis of such Depletable Property, up to an amount equal to the Partnerships Simulated Basis in such property at the time of such sale or
disposition. Thereafter, revenues resulting from any such sale or disposition shall be allocated to the Partners in a manner which will cause the aggregate of all revenues allocated to the Partners from such sale or disposition (to the extent
possible) to equal the amounts which would have been allocated under Section 4.2(a)(v) in the absence of this Section 4.2(a)(iii).

(iv) Revenues attributable to any Hedging Transaction shall be allocated 100% to the Limited Partner.

(v) All other revenues of the Partnership not specifically allocated above shall be allocated (A) to the General Partner in accordance with its GP Sharing Percentage and (B) to the Limited Partner in
accordance with its LP Sharing Percentage.

(b) All dry hole and bottom hole and similar contributions shall not be considered to be
revenues hereunder but shall be applied to reduce the Capital Costs of the respective wells to which they relate.

Section 4.3.
Income Tax Allocations. Except as otherwise provided herein, for purposes of any applicable federal, state or local income tax law, rule or regulation items of income, gain, deduction, loss, credit and amount realized shall be allocated
to the Partners as follows:

(a) Income from the sale of oil or gas production shall be allocated in the same manner as revenue therefrom is
allocated and credited pursuant to Section 4.2.

(b) Cost and percentage depletion deductions and the gain or loss on the sale
or other disposition of property the production from which is subject to depletion (herein sometimes called Depletable Property) shall be computed separately by the Partners rather than the Partnership. For purposes of
Section 613A(c)(7)(D) of the Internal Revenue Code, the Partnerships adjusted basis in each Depletable Property acquired by the Partnership shall be allocated to each Partner in an amount equal to the portion of the costs and expenses
which entered into such basis actually paid by such Partner or paid by the Partnership with funds contributed by or allocated to such Partner. The amount realized on the sale or other disposition of each Depletable Property shall be allocated to the
Partners in proportion to each Partners respective share of the revenue from the sale or other disposition of such property provided for in Section 4.2(a)(iii) or Section 4.2(a)(v), as applicable. For purposes of
allocating amounts realized upon any such sale or disposition which are deemed to be received for federal income tax purposes and 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(a)(ii).

(c) Items of deduction, loss and credit not specifically provided for above (other than loss from the sale or other disposition of Partnership property),
including depreciation, cost



---

recovery and amortization deductions, shall be allocated to the Partners in the same manner that the costs and expenses of the Partnership that gave rise to
such items of deduction, loss and credit were allocated pursuant to Section 4.1.

(d) Gain from the sale or other disposition
of Partnership property that is not specifically provided for above shall be allocated to the Partners in a manner which reflects each Partners allocable share of the revenue from the sale of the Partnership property provided for in
Section 4.2, and loss from the sale or other disposition of Partnership property that is not specifically provided for above shall be allocated to the Partners in a manner which reflects each Partners allocable share of the costs
and expenses of the Partnership property provided for in Section 4.1.

(e) All recapture of income tax deductions resulting
from the sale or other disposition of Partnership property shall, to the maximum extent possible, be allocated to the Partner to whom the deduction that gave rise to such recapture was allocated hereunder to the extent that such Partner is allocated
any gain from the sale or other disposition of such property.

(f) Income resulting from the Partnerships receipt of dry hole, bottom
hole or similar contributions shall be allocated in the same manner as the costs to which they were applied were allocated.

(g) Any other
items of Partnership income or gain not specifically provided for above shall be allocated in the same manner as the revenue that resulted in such income or gain is allocated and credited pursuant to Section 4.2.

(h) Notwithstanding any of the foregoing provisions of this Section 4.3 to the contrary:

(i) If during any fiscal year of the Partnership there is a net increase in Minimum Gain attributable to a Partner Nonrecourse Debt that
gives rise to Partner Nonrecourse Deductions, each Partner bearing the economic risk of loss for such Partner Nonrecourse Debt shall be allocated items of Partnership deductions and losses for such year (consisting first of cost recovery or
depreciation deductions with respect to property that is subject to such Partner Nonrecourse Debt and then, if necessary, a pro rata portion of the Partnerships other items of deductions and losses, with any remainder being treated as an
increase in Minimum Gain attributable to Partner Nonrecourse Debt in the subsequent year) equal to such Partners share of Partner Nonrecourse Deductions, as determined in accordance with applicable Treasury Regulations.

(ii) If for any fiscal year of the Partnership there is a net decrease in Minimum Gain attributable to Partnership Nonrecourse
Liabilities, each Partner shall be allocated items of Partnership income and gain for such year (consisting first of gain recognized, including Simulated Gain, from the disposition of Partnership property subject to one or more Partnership
Nonrecourse Liabilities and then, if necessary, a pro rata portion of the Partnerships other items of income and gain, and if necessary, for subsequent years) equal to such Partners share of such net decrease (except to the extent such
Partners share of such net decrease is caused by a change in debt structure with such Partner commencing to bear the economic risk of loss as to all or part of any Partnership



---

Nonrecourse Liability or by such Partner contributing capital to the Partnership that the Partnership uses to repay a Partnership Nonrecourse Liability), as
determined in accordance with applicable Treasury Regulations.

(iii) If for any fiscal year of the Partnership there is a
net decrease in Minimum Gain attributable to a Partner Nonrecourse Debt, each Partner shall be allocated items of Partnership income and gain for such year (consisting first of gain recognized, including Simulated Gain, from the disposition of
Partnership property subject to Partner Nonrecourse Debt, and then, if necessary, a pro rata portion of the Partnerships other items of income and gain, and if necessary, for subsequent years) equal to such Partners share of such net
decrease (except to the extent such Partners share of such net decrease is caused by a change in debt structure or by the Partnerships use of capital contributed by such Partner to repay Partner Nonrecourse Debt) as determined in
accordance with applicable Treasury Regulations.

(i) The General Partner shall use all reasonable efforts to prevent any allocation or
distribution from causing a negative balance in the Limited Partners Adjusted Capital Account. Consistent therewith, and notwithstanding any of the foregoing provisions of this Section 4.3 to the contrary, if for any fiscal year of
the Partnership the allocation of any loss or deduction (net of any income or gain) to any Partner would cause or increase a negative balance in such Partners Adjusted Capital Account as of the end of such fiscal year (the Deficit
Partner) after taking into account the provisions of subsection (h) of this Section 4.3, only the amount of such loss or deduction that reduces the balance to zero shall be allocated to such Deficit Partner and the
remaining loss or deduction shall be allocated to the Partner whose Adjusted Capital Account has a positive balance remaining at such time (the Positive Partner). After any such allocation, any Partnership income or gain
(including Simulated Gain) that would otherwise be allocated to the Deficit Partner shall be allocated instead to the Positive Partner up to an amount equal to the Partnership loss or deduction allocated to the Positive Partner under the preceding
sentence; provided, however, that no allocation of income or gain realized shall be made under this sentence if the effect of such allocation would be to cause the Adjusted Capital Account of the Deficit Partner to be less than zero. If, after
taking into account the allocation in the first sentence of this Section 4.3(i), the Adjusted Capital Account balance of the Deficit Partner remains less than zero at the end of a fiscal year, a pro rata portion of each item of
Partnership income or gain (including Simulated Gain) otherwise allocable to the Positive Partners for such fiscal year (or if there is no such income or gain allocable to the Positive Partners for such fiscal year, all such income or gain
(including Simulated Gain) so allocable in the succeeding fiscal year or years) shall be allocated to the Deficit Partner in an amount necessary to cause its Adjusted Capital Account balance to equal zero; provided, that no allocation under this
sentence shall have the effect of causing the Positive Partners Adjusted Capital Account to be less than zero. After any such allocation, any Partnership gain (including Simulated Gain) resulting from the sale or other disposition of
Partnership property that would otherwise be allocated to the Deficit Partner for any fiscal year under this Section 4.3 shall be allocated instead to the Positive Partner until the amount of gain so allocated equals the amount of gain
(including Simulated Gain) previously allocated to such Deficit Partner under the preceding sentence of this Section 4.3(i); provided, however, that no allocation of gain (including Simulated Gain) shall be made under this sentence if
the effect of such allocation would be to cause the Adjusted Capital Account of a Deficit Partner to be less than zero.



---

(j) In accordance with Section 704(c) of the Internal Revenue Code and the Treasury Regulations
thereunder, income and deductions with respect to any property carried on the books of the Partnership at a value that differs from such propertys adjusted tax basis shall, solely for federal income tax purposes, be allocated among the
Partners in a manner to take into account any variation between the adjusted tax basis of such property to the Partnership and its fair market value at the time of contribution or its book value, as applicable. In making such allocations, the
General Partner shall use such method or methods permitted under applicable Treasury Regulations as may be approved by the Limited Partner in accordance with Section 6.9(a).

Section 4.4. Distributions.

(a) Within 30 days after the end of each month, the General Partner shall cause the Partnership to make a distribution (i) to the Limited Partner of its LP Monthly Cash Distribution for such month and (ii) to the General Partner
of its GP Monthly Cash Distribution for such month.

(b) The General Partner shall cause the Partnership to make a distribution to the
Partners of their allocable share (as determined under Section 4.2(a)) of the net proceeds of sale resulting from any permitted sale or disposition of Leases or other Partnership assets (other than in connection with the liquidation of
the Partnership) within two business days after the closing of such sale or disposition; provided, that the General Partner shall be entitled to reserve from such distribution such amount which is, or which the General Partner reasonably anticipates
will be, subject to any post-closing adjustment and which reserve shall be approved by the Limited Partner; provided, further, that the General Partner shall distribute such reserve or portions thereof at such times as it reasonably determines that
the contingencies for which such reserve has been established have been satisfied.

(c) Notwithstanding the foregoing or any other
provision contained in this Agreement, (i) unless the Limited Partner otherwise consents in writing or defaults in the payment of any Capital Contributions previously agreed to be made by it, the General Partner shall not be entitled to cause
the Partnership to retain any of the Limited Partners share of Partnership revenues for the purpose of paying (directly or indirectly) any Acquisition Costs, Capital Costs, Hedge Costs, or Organization and Third Party Acquisition Costs or
(ii) the Partnership may retain such insurance proceeds and other amounts as the General Partner shall reasonably determine are necessary to pay Partnership liabilities and expenses upon the occurrence of an accident (e.g., a blowout),
catastrophe or similar event (and, in connection therewith, to restore, preserve or protect Partnership property) or to comply with all applicable Environmental Laws, ordinances, rules and regulations.

(d) Payment of all distributions made by the Partnership to the Limited Partner shall be made by wire transfer of immediately available funds in
accordance with such written instructions to the General Partner as may be provided by the Limited Partner from time to time.

(e) Nothing
contained in this Section 4.4 shall relieve the General Partner from its obligation to bear 100% of Catastrophe Costs pursuant to Section 4.1(a).



---

(f) All distributions in liquidation of a Partners interest in the Partnership shall be made in
accordance with Section 10.3.

ARTICLE V

PARTNERSHIP PROPERTY

Section 5.1. 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 all of its assets in the name of the Partnership unless under the law of some jurisdiction in which the Partnership owns assets such assets must be held in another name. In such a case, such assets in such jurisdiction shall
be held under such other name or names (except the name of the General Partner, any Affiliate of the General Partner or the name of the Limited Partner) as the General Partner shall determine to be necessary so long as it does not affect adversely
the limited liability of the Limited Partner hereunder or jeopardize in any manner the title to or ownership of any Partnership Leases or other assets. The General Partner shall promptly take all such action as it shall deem necessary or
appropriate, or as may be required by law, to perfect and preserve the ownership interest of the Partnership in all Leases, and (if requested by the Limited Partner) upon recordation of title to a Lease shall promptly supply the Limited Partner with
a copy of such recorded title. In the event the Partnership acquires assets in a jurisdiction which prohibits the Partnership from holding such assets in the name of the Partnership and such assets are held in another name, the General Partner shall
obtain an opinion of reputable counsel in such jurisdiction addressed to the Limited Partner and satisfactory in all respects to the Limited Partner that the Partnership has taken all action necessary and appropriate, or required by law, to perfect
and preserve the ownership interest of the Partnership in all such assets.

Section 5.2. Acquisition of the Properties.

(a) Immediately after the execution and delivery of this Agreement by the parties hereto, the General Partner is authorized to, and shall,
execute and deliver on behalf of the Partnership the Assignment Agreement and that certain Purchase and Sale Agreement (the Purchase Agreement) by and between the Partnership, as buyer, and B&W Operating, L.L.C., et al., as
seller, provided the Purchase Agreement and the Assignment Agreement are substantially in the forms of the versions submitted to and approved by the Partners on or prior to the date hereof as the final draft in all material respects.

(b) If the Purchase Agreement and the Assignment Agreement are executed and delivered by the General Partner on behalf of the Partnership in accordance
with subsection (a) above, the General Partner shall cause the Partnership to consummate the acquisition of the Properties pursuant to the terms and conditions of the Purchase Agreement and the Assignment Agreement, provided that the
conditions set forth in Section 3.2(e) to the Limited Partners obligation to make the Capital Contribution referenced in Section 3.2(c)have been satisfied.

Section 5.3. Additional Acquisitions. If, during the term of this Agreement but after the Purchase Agreement Closing Date, the General
Partner or an Affiliate thereof acquires (or proposes to acquire) a Lease or Leases inside of the Area of Mutual Interest (in this Section called the Subject Leases), the terms and provisions of this Section 5.3 shall
be operative.



---

Specifically, upon the acquisition (or proposed acquisition) under the circumstances described above, the General Partner shall notify the Limited Partner,
which notice shall (a) specify the interest the General Partner or its Affiliates have acquired (or propose to acquire) in the Subject Leases, (b) specify the purchase price (or proposed purchase price), (c) describe the development
and/or Enhanced Recovery Operations, if any, the General Partner reasonably anticipates will be engaged in on the Subject Leases and the estimated costs associated therewith, (d) include a summary of the pertinent geological and geophysical
data relating to the Subject Leases or proposed development/Enhanced Recovery Operations, (e) include financial projections relating to the Subject Leases and any internally or externally prepared related engineering or reserve reports,
(f) describe the nature and extent of planned title examination and property related due diligence (including, without limitation, environmental due diligence), and (g) such other information as the General Partner deems material,
including the depths to be acquired and whether the Partnership or a third party presently owns such depths as covered by the Subject Leases in the Area of Mutual Interest. Thereafter, the General Partner shall promptly furnish to the Limited
Partner any additional information concerning the Subject Leases or the proposed development/Enhanced Recovery Operations as the Limited Partner may reasonably request (including, without limitation, the reports of consultants and outside
engineers). Subject to the Limited Partner agreeing to make additional Capital Contributions to the Partnership with respect to the Subject Leases pursuant to Section 3.3 or as otherwise provided below in this Section 5.3,
the Partnership shall acquire not less than all of the interest of the General Partner and its Affiliates in such Subject Leases (or, if applicable, which the General Partner or its Affiliates propose to acquire therein) pursuant to the terms set
forth in the notice. Prior to the acquisition by the Partnership of the Subject Leases, the General Partner shall notify the Limited Partner of any material change in the nature and extent of the title examination and property related due diligence
plan and the reason therefor and of any fact discovered in due diligence that materially adversely affects the economics or risks associated with the Subject Leases; provided that no such notice need be given to the Limited Partner if the Limited
Partner has elected not to make additional Capital Contributions with respect thereto. The Limited Partner may withdraw its election to make additional Capital Contributions with respect to the proposed acquisition and related activity, at any time
prior to the Partnership committing to acquire the Subject Leases, by so notifying the General Partner in writing if (i) there is discovered during due diligence a fact or facts not presented to the Limited Partner in the initial evaluation of
the proposed acquisition that materially adversely affects the economics or risks associated with the Subject Leases to be acquired and such material adverse effect cannot be remedied to the reasonable satisfaction of the Limited Partner prior to
the acquisition by the Partnership or (ii) more than three months have passed since the Limited Partner notified the General Partner of such Limited Partners election to make Capital Contributions with respect to such acquisition and
related activity. The interest in each Lease assigned by the General Partner and each Affiliate thereof to the Partnership pursuant to this Section 5.3 shall be assigned, conveyed and transferred without warranty of title, either express
or implied, except as to all persons claiming or to claim the same or any part thereof by, through and under the General Partner or such Affiliate but not otherwise and with a further warranty that the General Partner or such Affiliate has not
placed any lien, encumbrance, burden or other restriction on such Lease or, if the General Partner or such Affiliate has previously placed a lien, encumbrance, burden or other restriction on such Lease, that such lien, encumbrance, burden or other
restriction is being concurrently released or has been released. In connection with any acquisition of Leases by the Partnership pursuant to this Section 5.3, the General Partner or an Affiliate thereof shall not retain from or otherwise
burden



---

the interest in any Lease assigned to the Partnership with any overriding royalty, net profits interest, carried interest, reversionary interest, production
payment or other burden in favor of itself, its officers, managers, directors and employees or any other person, except in connection with an acquisition by the General Partner or such Affiliate pursuant to a transaction where an unrelated third
party transferring the Lease retains such an interest or burden with respect to all of the Lease acquired by the General Partner or Affiliate. With respect to each Lease acquired by the Partnership pursuant to this Section 5.3, such
acquisition shall include all rights to all horizons under such Lease which were available for purchase and considered appropriate for acquisition by the Partnership. Under no circumstances shall the General Partner or any Affiliate thereof acquire
rights to any separate horizon within or under a Lease in which the Partnership has an interest without first offering such rights to the Partnership under this Section 5.3.

Section 5.4. Lease Sales.

(a) Except as provided in this Section 5.4, in Section 6.2(d), and elsewhere herein, the General Partner may sell, farm-out, abandon or otherwise dispose of any Partnership Lease, on such terms as the General Partner
deems reasonable and in the best interests of the Partnership and the Limited Partner.

(b) Except as expressly permitted and recognized in
Section 5.3 and Section 10.3, neither the General Partner or any of its Affiliates nor any of their employees shall acquire, directly or indirectly, any Lease (or any interest therein) from the Partnership unless the Limited
Partner has previously approved in writing such acquisition.

Section 5.5. Sales of Production. The General Partner
shall have the right to cause the Partnership to sell any oil or gas produced by or for the account of the Partnership, including but not limited to crude oil, condensate, natural gas liquids and natural gas (including casinghead gas) which may be
produced from or allocated to the Oil and Gas Properties or any additional Leases acquired pursuant to the terms hereof, to such purchaser and on such terms and conditions as the General Partner shall determine to be in the best interest of the
Partnership; provided, however, that all such sales shall be upon terms and conditions which are the best terms and conditions available as determined in good faith by the General Partner taking into account all relevant circumstances, including but
not limited to, price, quality of production, access to markets, minimum purchase guarantees, identity of purchaser, and length of commitment and, in any event, on terms no less favorable to the Partnership than the General Partner or any Affiliate
thereof has recently obtained or is obtaining for arms length sales, exchanges or dispositions of the General Partners or such Affiliates production of similar quantity and quality in the same geographic area where the
Partnerships production is located.

Section 5.6. Operations on Partnership Leases.

(a) The General Partner or an Affiliate thereof, shall act as operator in connection with operations on each Partnership Lease and, subject to
subsection (b) below, receive compensation and reimbursement from the Partnership in connection therewith (regardless of whether there is an operating agreement) unless (i) another person is serving as operator under an agreement to
which a Lease is subject or (ii) any third party or third parties (not Affiliates of the General Partner) jointly owning such Lease and with a controlling interest will not agree. As to those Partnership Leases with respect to which the General
Partner is not the operator, the



---

General Partner shall take such actions and exercise such rights and remedies that are reasonably available to it to cause the actual operator to properly
develop, maintain and operate such Leases.

(b) In the event the Partnership and any third party jointly own any Lease and operations
thereon are conducted pursuant to an operating agreement, (i) if the third party is designated as operator thereunder, the Partnership shall pay the costs and expenses charged to it thereunder and (ii) if the General Partner or any of its
Affiliates is designated as operator, the General Partner or such Affiliate shall receive for its account from the third party such third partys share and from the Partnership the Partnerships share of all compensation and reimbursement
provided to the operator thereunder; provided, however, that the charges to the Partnership by the General Partner or any of its Affiliates when acting as the designated operator (regardless of whether there is an operating agreement or regardless
of whether or not a third party is also a party thereto) shall not exceed those set forth in or permitted by this Agreement or the Accounting Procedure (as herein called) attached hereto as Exhibit 5.6 (although the
operating agreement, if any, may otherwise provide), and in no event shall the terms of any such operating agreement vary or effect this Agreement or the Accounting Procedure or the duties and obligations of the General Partner hereunder (and in the
event of a conflict the terms and provisions of this Agreement shall prevail).

(c) Other than assignments among the General Partner and
entities which are Affiliates of the General Partner pursuant to clause (c) of the definition thereof, the General Partner, or any such Affiliate, shall not substitute another party as operator, resign as operator or assign its
obligations as operator with respect to any Partnership Lease where it acts as operator, unless the Limited Partner so requests in the event the General Partner is removed as such pursuant to Section 9.4 or the Limited Partner elects to
wind-up the Partnership pursuant to any of subsections (c), (e), (f), (g), or (i) of Section 10.1 (in which event the General Partner agrees that it or its Affiliates will immediately resign
as operator and use its reasonable best efforts to cause the person designated by the Limited Partner to be the successor operator and to act in good faith and cooperate in all respects with the Partnership, the Limited Partner, and the successor
operator in transferring operations and in effecting an efficient and successful transition).

Section 5.7. Hedge
Arrangement. Subject to the terms and conditions below, the General Partner will cause the Partnership, when and if requested by the Limited Partner either on or prior to or after the Purchase Agreement Closing Date to hedge up to the
product of 85% multiplied by the LP Sharing Percentage of the Partnerships forecast production from proved producing oil and gas reserves attributable to the Oil and Gas Properties and any additional Leases acquired pursuant to the terms
hereof as determined in the CGA Report for such period and on such terms and conditions as are satisfactory to the Limited Partner. Notwithstanding the foregoing, it is agreed that the General Partners obligation under the immediately
preceding two sentences shall be conditioned upon the General Partner having received from the Limited Partner reasonable assurance that the Limited Partner has the financial ability to fund Hedge Costs attributable to the subject Hedging
Transaction (it being agreed, however, that the guaranty by GE Capital Corporation of the Partnerships funding obligations in respect of such Hedging Transaction shall be deemed to satisfy this condition). Any Hedging Transaction contemplated
hereunder shall be a hedging transaction as described in Treasury Regulation §1.1221-2 to reduce the risk of price changes for oil and gas produced by the Partnership in volumes equal to the notional amounts provided in the
documents evidencing such Hedging Transaction. At the



---

time of the execution and delivery by the Partnership of the documents evidencing a Hedging Transaction, the General Partner shall take such additional steps
as may be necessary to identify the Hedging Transaction in the books and records of the Partnership as a hedging transaction in the manner and at the time prescribed by Treasury Regulation §1.1221-2(f).

Section 5.8. Production. Throughout the term of the Partnership, the General Partner shall instruct any operator of any Partnership
Lease to produce on behalf of the Partnership not less than the Partnerships entire working interest in the production attributable to such Lease; provided, however, the General Partner shall not be so obligated (a) in circumstances when
it is necessary to restrict production on such Lease for the purpose of performing general maintenance and workover activities thereon in connection with maintaining production; (b) if the Partnership is precluded from so doing by any
applicable state, local or federal law, order or regulation; (c) if the Production Sales Proceeds attributable to such Lease are inadequate to cover Lease Operating and Production Costs attributable thereto; or (d) if the General Partner
gives notice to the Limited Partner that due to a cause or causes beyond the reasonable control of the General Partner, including, for purposes of illustration, an act of God, strike, act of public enemy, war, blockade, public riot, lightening,
fire, violent storm, flood, explosion or governmental restraint, it is unable to do so.

Section 5.9. Environmental, Health and
Safety Program. The General Partner, at the cost and expense of the Partnership, shall implement, and maintain a formal, comprehensive written environmental health and safety program (in this Section, the EH&S
Program), including regular review and evaluations, aimed at ensuring that the Partnerships operations on the Oil and Gas Properties or any additional Leases acquired pursuant to the terms hereof are conducted in compliance with all
applicable Environmental Laws. At a minimum, the EH&S Program shall include: (a) identification of environmental concerns associated with any environmental regulations applicable to the Partnerships operations; (b) adoption and
implementation of an environmental management system to assess and control the environmental impact of the Partnerships operations; and (c) implementation of periodic EH&S audits conducted either internally or by independent
consultants with documented corrective action responding to such audits. The EH&S Program shall involve senior management of the General Partner, include a formal written corporate environmental policy, and identify by name or position the

administrative adjustment, file suit concerning any tax refund or deficiency relating to any Partnership administrative adjustment or enter into any settlement agreement relating to any Partnership item of income, gain, loss, deduction or credit for
any fiscal year of the Partnership.

Section 6.11. Appointment of Trustee to Receive Payments. The Limited Partner may
cause the Partnership at the Partnerships expense to assign the Partnerships right to receive revenues to a trustee named by the Limited Partner (a) if the General Partner has committed fraud, willful or intentional misconduct or

warranty made by the General Partner herein or by the General Partner or any of its officers in any writing furnished in connection with or pursuant to this Agreement shall be false in material respect on the date as of which made, or (d) upon

event under or with respect to the bankruptcy law is completely dismissed or eliminated, the General Partner and the Limited Partner shall, at the request of either the General Partner or the Limited Partner, cause the trustee to be discharged at
the Partnerships expense; provided that in the reasonable judgment of the Limited Partner, its interest under this Agreement will not be adversely affected by any such discharge.

the filing of a Texas margin tax combined group report, the parties agree that the Partnership shall promptly reimburse the Limited Partner for the margin tax paid on behalf of the Partnership as a combined group member. The margin tax paid on
behalf of the Partnership shall be equal to the margin tax that the Partnership would have paid if it had computed its margin tax liability for the report period on a separate entity basis rather than as a member of the combined group. The parties
agree that the Limited Partner may deduct for federal income tax purposes 100% of the Texas margin tax attributable to the Partnership and paid by the Limited Partner and that the Partnerships reimbursement obligation shall be limited to the
after-tax cost of the Texas margin tax attributable to the Partnership and paid by the Limited Partner, computed based on the highest marginal federal tax rate applicable to corporations.

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 Internal Revenue Code). Immediately prior to any distribution of assets
by the Partnership that is not pursuant to a liquidation of the Partnership or all or any portion of a Partners interest therein, the Partners capital accounts shall be adjusted by (X) 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 (Y) crediting or debiting each Partners capital account with its respective share of the hypothetical gains or
losses, including Simulated Gains and Simulated Losses, resulting from such assumed sales in the same manner as each such capital account would be debited or credited for gains or losses on actual sales of such assets. Notwithstanding the foregoing
sentence, the Partnership shall not distribute any property in kind to any Partner except as provided in Section 10.3.

(ii) The allocation of basis prescribed by Section 613A(c)(7)(D) of the Internal Revenue Code and provided for in Section 4.3(b) 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 Internal Revenue 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 (determined under
Section 4.3(b)) with respect to which such depletion is claimed (herein called Simulated Depletion). The Partnerships basis in any Depletable 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, which share shall be determined in the same manner as



---

the allocation of basis prescribed in Section 4.3(b)) 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 allocable share of the Partnerships remaining Simulated Basis in such property. The
Partnership shall compute simulated gain (Simulated Gain) or simulated loss (Simulated Loss) attributable to the sale or other disposition of a Depletable Property based on the difference between the amount
realized from such sale or other disposition and the Simulated Basis of such property, as theretofore adjusted. Any Simulated Gain shall be allocated to the Partners and shall increase their respective capital accounts in the same manner as the
amount realized from such sale or other disposition in excess of Simulated Basis shall have been allocated pursuant to Section 4.3(b). Any Simulated Loss shall be allocated to the Partners and shall reduce their respective capital
accounts in the same percentages as the costs of the property sold were allocated up to an amount equal to each Partners share of the Partnerships Simulated Basis in such property at the time of such sale.

(iii) Any adjustments of basis of Partnership property provided for under Sections 734 and 743 of the Internal Revenue Code and
comparable provisions of state law (resulting from an election under Section 754 of the Internal Revenue Code or comparable provisions of state law) and any election by an individual Partner under Section 59(e)(4) of the Internal Revenue
Code to amortize such Partners share of intangible drilling and development costs shall not affect the capital accounts of the Partners (unless otherwise required by applicable Treasury Regulations), and the Partners capital accounts
shall be debited or credited pursuant to the terms of this Section 8.1 as if no such election had been made.

(iv) Capital accounts shall be adjusted, in a manner consistent with this Section 8.1, 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 carried on the books of the Partnership at an amount which differs from its adjusted basis, the Partners capital accounts shall be debited or credited for items of depreciation, cost recovery, Simulated Depletion, amortization and
gain or loss (including Simulated Gain or Simulated 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 such book value, 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 accounts 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 General Partner is hereby authorized to make such adjustment after notice to the Limited Partner.

Partnership and the costs charged to the General Partner and the costs charged to the Limited Partner, the total revenues of the Partnership and the revenues credited to the account of the General Partner and to the account of the Limited Partner,

have agreed in writing to accept the responsibilities of a General Partner; and (ii) this Agreement and the Certificate of Formation of the Partnership shall have been duly amended to name the new General Partner hereunder and under the laws of

Transfer Notice) describing the interest (or portion thereof) that is the subject of such proposed disposition (in this Section 9.6, the Offered Interest) and requesting that the General Partner
submit an offer to purchase the Offered Interest. The General Partner shall thereupon have 30 days after receipt of the Transfer Notice to submit an offer in writing to the Limited Partner to purchase the Offered Interest, which offer shall be in
reasonable detail. Failure of the General Partner to submit an offer in writing to the Limited Partner to purchase the Offered Interest within such 30-day period shall be deemed an election by the General Partner not to submit an offer. If the
General Partner submits an offer in writing to purchase the Offered Interest in accordance with this Section, the Limited Partner shall have the option to accept such offer, to decline the offer and retain the Offered Interest, or to sell the
Offered Interest to a third party, provided that (i) any sale to a third party is consummated within 120 days after the expiration of the above 30-day period and is on terms and conditions no less favorable to the Limited Partner than those
contained in the offer submitted by the General Partner and (ii) the terms of Section 9.1 are complied with. If the General Partner elects not to, or fails to, deliver any such offer in writing to the Limited Partner within such
30-day period, the Limited Partner shall have the option to sell the Offered Interest to a third party on such terms and conditions as agreed upon between them, provided that any such sale is consummated within 120 days after the expiration of the
above 30-day period and the terms of Section 9.1 are complied with.

(b) If the Limited Partner elects to accept an offer of
the General Partner to purchase the Offered Interest as provided in subsection (a) above, the closing of the purchase and sale of an Offered Interest shall take place on the 45th day following the date of delivery to the General Partner
of the Limited Partners election to accept such offer (or if such day is a Saturday, Sunday, or legal holiday in the State of Connecticut, the first day thereafter that is not a Saturday, Sunday, or legal holiday) at 10:00 a.m., local time, in
the offices of the Limited Partner set forth on the Limited Partners signature page of this Agreement, or on such other date and at such other time and place as may be agreed to by both Partners. At the closing, the Limited Partner shall take
all action necessary to convey the Offered Interest to the General Partner, free of all liens and encumbrances, against receipt of the purchase price therefor.

(a) The liquidator shall continue to operate the Partnership properties with all of the power and authority of the General Partner, and, as soon as
reasonably possible, unless directed otherwise by the Limited Partner, shall take all steps reasonably necessary to market and sell the Partnership or its assets to a bona fide third-party purchaser on the best terms and conditions available to the

(b) As promptly as possible, and, in any event, within 45 days after winding-up and again after final liquidation (unless, in either instance, waived by
the Limited Partner), the liquidator shall cause a proper accounting to be made by the Partnerships independent accountants of the Partnerships assets, liabilities and operations through the last day of the month in which the winding-up
occurs or the final liquidation is completed, as appropriate.

(c) The liquidator shall pay all of the debts and liabilities of the
Partnership or otherwise make adequate provision therefor (including the establishment of a cash escrow fund



---

for contingent liabilities in such amount and for such term as the liquidator may reasonably determine and as the Limited Partner shall approve).

(d) If the Limited Partner elects to have the liquidating distributions of the Partnership made in kind, after making payment or provision for all
debts and liabilities of the Partnership, the Partners capital accounts shall then be adjusted by (i) assuming the sale of all remaining assets of the Partnership for cash at their respective fair market values (as determined by an
appraiser selected by the Limited Partner within 30 days after receipt by the Limited Partner of notice that the liquidator has paid or made provision for all debts and liabilities of the Partnership or as of the date of termination of the
Partnership, (ii) assuming the distribution of such cash at such time in the percentages required under Section 4.2 and Section 4.4, taking into account whether Cumulative Payout has occurred or would occur as a result
of such distribution, and (iii) debiting or crediting each Partners capital account with its respective share of the hypothetical gains or losses resulting from such assumed sales in the same manner as each such capital account would be
debited or credited for gains or losses on actual sales of such assets. In the event that the Limited Partner fails to notify the General Partner of its selection of an appraiser pursuant to the preceding sentence within the time period specified
therein, the General Partner shall be entitled to select such appraiser. The liquidator shall then by payment of property (valued as of the date of termination of the Partnership at its fair market value by the appraiser selected in the manner
provided above) distribute to the Partners such amounts as are required to pay the positive balances of their respective capital accounts. In making distributions of property in satisfaction of such capital account balances, the liquidator shall
distribute, to the extent possible, undivided interests in each Lease in the same percentages as the Partners share revenues from such Lease. Each Partner shall have the right to designate another person to receive any property which otherwise would
be distributed in kind to that Partner pursuant to this Section 10.3 and Section 10.2 if that Section is applicable. Any distributions to the Partners in liquidation of the Partnership shall be made by the later of the end of
the taxable year in which the liquidation occurs, or 90 days after the date of such liquidation. For purposes of the preceding sentence, the term liquidation shall have the same meaning as set forth in Treasury Regulation
§1.704-1(b)(2)(ii)(g) as in effect at such time.

(e) If the Limited Partner does not elect to have the liquidating distributions of
the Partnership made in kind, after making payment or provision for all debts and liabilities of the Partnership, the Partners capital accounts shall then be adjusted by debiting or crediting each Partners capital account with its
respective share of the gains or losses resulting from the actual sale of Partnership assets in connection with the liquidation under Section 10.3(a) and, for purposes of determining the applicable GP Sharing Percentage and LP Sharing
Percentages, assuming the distribution of all cash available after the sale of the assets of the Partnership in the percentage required under Section 4.2 and Section 4.4 taking into account whether Cumulative Payout has
occurred or would occur as a result of such distribution. The liquidator shall then, by payment of cash, distribute to the Partners such amounts as are required to pay the positive balances of their respective capital accounts. Any distributions to
the Partners in liquidation of the Partnership shall be made by the later of the end of the taxable year in which the liquidation occurs, or 90 days after the date of such liquidation. For purposes of the preceding sentence, the term
liquidation shall have the same meaning as set forth in Treasury Regulation §1.704-1(b)(2)(ii)(g) as in effect at such time.



---

(f) The provisions of subsection (d) and subsection (e) of this
Section 10.3 shall be subject to the effect of Section 10.2 if that Section is applicable.

(g) Except as expressly
provided herein, the liquidator shall comply with any applicable requirements of the TLPL and all other applicable laws pertaining to the winding up of the affairs of the Partnership and the final distribution of its assets.

(h) The distribution of cash to the Limited Partners in accordance with the provisions of this Section 10.3 shall constitute a complete
return to the Limited Partner of its Capital Contributions and a complete distribution to the Limited Partner of its interests in the Partnership and all Partnership property.

(i) No Partner with a negative balance in its capital account shall be liable to the Partnership or any other Partner for the amount of such negative
balance upon winding-up and liquidation.

Section 10.4. Cancellation of Certificate. Upon the completion of the
distribution of Partnership assets as provided herein, the Partnership shall be terminated, and the liquidator (or the Partners if necessary) shall cause the cancellation of the Certificate of Formation of the Partnership and shall take such other
actions as may be necessary to terminate the Partnership.

EXHIBIT 8.2(j)(iii)

EXAMPLE OF FAS 133 HEDGE DOCUMENTATION

Oil Hedge

Hedge Execution Date

Overview

[l]([l] or the Company) is a private limited
partnership which owns mineral interests in more than  producing oil and gas wells and 
non-producing oil and gas wells and locations in . EFS O&G, LLC, a wholly owned subsidiary of GE Energy Financial Services, Inc. (EFS or LP)
acquired a % interest in [l] for $MM, and
is the limited partner of [l]. [l] (GP) owns a % interest in
[l], and is the general partner of [l].

[l] uses a series of annual floating-to-fixed rate commodity swaps to hedge the price risk associated with changes in the price of the oil production allocated to EFS. NYMEX Crude Oil West Texas Intermediate
(WTI) is the proxy for [l]s selling price of the oil production allocated to EFS. GECC is guarantor to the swaps.

This program documentation is divided into six sections:



| |  |  | Risk Objective and Strategy
| | - |  | ---------------------------



| |  |  | Nature of the Hedging Relationship (FAS133 Designation)
| | - |  | -------------------------------------------------------

| | - |  | --------------------------------------------------

How This Documentation Will Be Used

Readers of financial statements can reference this document to understand hedge program fundamentals
(objectives, approved hedging instruments, effectiveness tests, etc.). Individual hedges will be executed, however this document will serve as FAS 133 hedge documentation for the program and will be filed within the Finance department of the GP
contemporaneously at the time of hedge election. Any incremental hedges executed over and above the initial hedges for a given month will be referenced by way of updating the table attached below.

Identification of the hedged item & hedging instrument, effectiveness testing method and OCI relief instructions will be based on the information contained in
this document and are specific to the [l] hedge.

Risk Objective and Strategy

Annual volatility in the WTI can exceed 50%, thereby posing significant earnings and cash flow risks. The risk being hedged is the fluctuation in cash flows for
forecasted PDP production due to the WTI volatility. An independent engineering consultant forecasted the PDP volumes to be produced by [l] and allocated to EFS at the acquisition date. The objective
of [l] in executing



---

the hedge is to mitigate the WTI volatility that could adversely affect forecasted cash flows and earnings related to such production.

Nature of the Hedging Relationship (FAS 133 Designation)

Cash flow hedge  forecasted purchases of oil

Identification of
Hedged Item

Identification of Hedged ItemPrice

The
hedged item will be the sale of monthly oil production allocated to EFS at [l]s spot price equal to the notional amount in bbls as outlined in Table A. As previously noted the monthly WTI
prices are the primary proxies for pricing [l]s physical sales of oil in this region. [l]s physical supply contracts are with third parties
and are based on the WTI prices adjusted for basis differentials for quality and transportation. Where contracts are being aggregated for hedging purposes under the program, [l] has performed and documented the
results of similarity tests performed on the various contracts being aggregated for hedging purposes under the program to meet the aggregation of similar risk exposures criteria under FAS 133.

Identification of Hedged ItemVolume

The sales volumes represent the
first sales of oil for the relevant period. Specific monthly volumes under hedge, as outlined in the swap confirmation, were based on 85% of forecasted monthly PDP oil production as per the original engineering report. Past experience has
shown that these forecasts are accurate, and therefore, we deem the production amounts included in these forecasts to be highly probable.

Credit Risk
Exposure

Exposure limits with financial institutions are approved by name and dollar exposure. Although a change in counterparty creditworthiness would not
necessarily indicate that the counterparty would default on its obligations, such a change would warrant further investigation.

Identification of
Hedging Instrument

Approved Derivatives

The financial
instrument identified below will be used to hedge the cash flow exposure for [l].



| |  |  | Over the Counter (OTC) swaps settled against NYMEX: Crude Oil West Texas Intermediate (WTI) settlement price.
| | - |  | -------------------------------------------------------------------------------------------------------------



---

Trade Details

The notional
amounts by term (volumes hedged), variable floating rate index price, fixed price, and forecasted PDP volumes along with description of hedge settlement will be designated for each hedge by [l]. These
terms will also be identified in each individual trade confirmation to be maintained by GECC.

Measuring Hedge Effectiveness

In order to qualify for hedge accounting both at inception of the hedge and on an ongoing basis, prospective and retrospective effectiveness assessment tests (see below)
will be performed to prove that the hedging relationship will be highly effective in achieving offsetting cash flows attributable to the hedged risk during the term of the hedge.

Prospective (Upon Inception) Effectiveness Test

It includes performing (upon hedge inception) a regression analysis of
actual monthly weighted average oil price realized by [l] for its oil sales to its customers versus the actual WTI settlement price. Actual monthly weighted average oil price realized by [l] is calculated by adding up the total revenues received by [l] for oil sales to its customers and dividing it by the total monthly quantity of oil sold by
[l] to its customers. Upon hedge inception the test will be performed utilizing at least 15 monthly historical data points. Subsequently, it will be performed quarterly (during the last month of the
fiscal quarter). In order to qualify for hedge accounting, the regression analysis should reflect the following results:

The results of the tests performed upon inception are maintained by GECC and supplied to the GP for [l]s records.

Retrospective (Quarterly) Effectiveness Test

The tests will be performed on a quarterly basis for the purpose of determination of the continuance of Cash Flow Hedge Accounting designation and application or potential de-designation due to test failure. The test
will include performing regression analysis detailed above in the Prospective Effectiveness Test.

Actual Ineffectiveness

Hypothetical derivative method (Per DIG Issue G7) will be utilized to measure the portion of the hedge results deemed to be effective and ineffective. A hypothetical
forward curve (for each hedging relationship) will initially be created with a strike price calculated based on the actual WTI forward curve at hedge inception.

Accumulated other comprehensive income associated with the hedged transaction shall be adjusted to a balance that reflects the lesser of the following (in absolute amounts):



|(1) | The cumulative gain or loss on the derivative from inception of the hedge less the derivatives gains or losses previously reclassified from accumulated other comprehensive
income into earnings.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

|(2) | The portion of the cumulative gain or loss on the derivative necessary to offset the cumulative change in expected future cash flows on the hedged transaction from inception of the
hedge less the derivatives gains or losses previously reclassified from accumulated other comprehensive income into earnings.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

A gain
or loss shall be recognized in earnings, as necessary, for any remaining gain or loss on the hedging derivative or to adjust other comprehensive income to the balance specified above. The ineffective portion would be the amount of change in fair
value of the hedge that is greater than the change in fair value of the hypothetical derivative on an absolute basis.

Relief of Other Comprehensive
Income Account (OCI)

OCI will be released into P&L as and when the hedged oil sales occur and the monthly contract settles. Amounts will be cleared
to the Income Statement utilizing a revenue account.

Natural Gas Hedge

Hedge Execution Date

Overview

[l] ([l] or the Company) is a private limited partnership which owns mineral interests in more than
 producing oil and gas wells and  non-producing oil and gas wells and locations in
. EFS O&G, LLC, a wholly owned subsidiary of GE Energy Financial Services, Inc. (EFS or LP) acquired a
% interest in [l] for $MM, and is the
limited partner of [l]. [l] (GP) owns a % interest in
[l], and is the general partner of [l].

[l] uses a series of annual floating-to-fixed rate commodity swaps to hedge the price risk associated with changes in the price of the natural gas production allocated to EFS. The NYMEX Houston Ship Channel
Natural Gas Index (NG) is the proxy for [l]s selling price of the natural gas production allocated to EFS. GECC is guarantor to the swaps.

How This Documentation Will Be Used

Readers of financial statements can reference this document to understand hedge program fundamentals
(objectives, approved hedging instruments, effectiveness tests, etc.). Individual hedges will be executed, however this document will serve as FAS 133 hedge documentation for the program and will be filed within the Finance department of the GP
contemporaneously at the time of hedge election. Any incremental hedges executed over and above the initial hedges for a given month will be referenced by way of updating the table attached below.

Identification of the hedged item & hedging instrument, effectiveness testing method and OCI relief instructions will be based on the information contained in
this document and are specific to the [l] hedge.

Risk Objective and Strategy

Annual volatility in the NG can exceed 50%, thereby posing significant earnings and cash flow risks. The risk being hedged is the fluctuation in cash flows for forecasted
PDP production due to the NG volatility. An independent engineering consultant forecasted the PDP volumes to be produced by [l] and allocated to EFS at the acquisition date. The objective of [l] in executing the hedge is to mitigate the NG volatility that could adversely affect forecasted cash flows and earnings related to such production.

Nature of the Hedging Relationship (FAS 133 Designation)

Cash flow hedge  forecasted purchases of natural gas

Identification of Hedged Item

Identification of Hedged ItemPrice

The hedged item will be the sale of monthly natural gas production allocated to EFS at [l]s spot price equal to the notional amount in mmbtu as outlined in
Table A. As previously noted the monthly NG prices are the primary proxies for pricing [l]s physical sales of natural gas in this region. [l]s physical supply contracts are with third parties and are based on the NG prices adjusted for basis differentials for quality and transportation. Where contracts are being aggregated for hedging
purposes under the program, [l] has performed and documented the results of similarity tests performed on the various contracts being aggregated for hedging purposes under the program to meet the aggregation
of similar risk exposures criteria under FAS 133.

Identification of Hedged ItemVolume

The sales volumes represent the first sales of natural gas for the relevant period. Specific monthly volumes under hedge, as outlined in the swap confirmation,
were based on 85% of forecasted monthly PDP natural gas production as per the original engineering report. Past experience has shown that these forecasts are accurate, and therefore, we deem the production amounts included in these forecasts to be
highly probable.

Credit Risk Exposure

Exposure limits with
financial institutions are approved by name and dollar exposure. Although a change in counterparty creditworthiness would not necessarily indicate that the counterparty would default on its obligations, such a change would warrant further
investigation.

Identification of Hedging Instrument

Approved Derivatives

The financial instrument identified below will be used to hedge the cash flow exposure for [l].



| |  |  | Over the Counter (OTC) swaps settled against NYMEX: Houston Ship Channel Natural Gas (NG) settlement price.
| | - |  | -----------------------------------------------------------------------------------------------------------

Trade Details

The notional
amounts by term (volumes hedged), variable floating rate index price, fixed price, and forecasted PDP volumes along with description of hedge settlement will be designated for each hedge by [l]. These
terms will also be identified in each individual trade confirmation to be maintained by GECC.

Measuring Hedge Effectiveness

In order to qualify for hedge accounting both at inception of the hedge and on an ongoing basis, prospective and retrospective effectiveness assessment tests (see below)
will be performed to prove that the hedging relationship will be highly effective in achieving offsetting cash flows attributable to the hedged risk during the term of the hedge.

Prospective (Upon Inception) Effectiveness Test

It includes performing (upon hedge inception) a regression analysis of
actual monthly weighted average natural gas price realized by [l] for its natural gas sales to its customers versus the actual NG settlement price. Actual monthly weighted average natural gas price
realized by [l] is calculated by adding up the total revenues received by [l] for natural gas sales to its customers and dividing it by the total
monthly quantity of natural gas sold by [l] to its customers. Upon hedge inception the test will be performed utilizing at least 15 monthly historical data points. Subsequently, it will be performed
quarterly (during the last month of the fiscal quarter). In order to qualify for hedge accounting, the regression analysis should reflect the following results:



| |  |  | 1 >= R-square >= 0.80, Slope is 0.80  1.25 and F stat passes at 95% confidence level, is required for prospective Cash Flow Designation.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------

The results of the tests performed upon inception are maintained by GECC and supplied to the GP for [l]s records.

Retrospective (Quarterly) Effectiveness Test

The tests will be performed on a quarterly basis for the purpose of determination of the continuance of Cash Flow Hedge Accounting designation and application or potential de-designation due to test failure. The test
will include performing regression analysis detailed above in the Prospective Effectiveness Test.

Actual Ineffectiveness

Hypothetical derivative method (Per DIG Issue G7) will be utilized to measure the portion of the hedge results deemed to be effective and ineffective. A hypothetical
forward curve (for each hedging relationship) will initially be created with a strike price calculated based on the actual NG forward curve at hedge inception.

Accumulated other comprehensive income associated with the hedged transaction shall be adjusted to a balance that reflects the lesser of the following (in absolute amounts):



|(1) | The cumulative gain or loss on the derivative from inception of the hedge less the derivatives gains or losses previously reclassified from accumulated other comprehensive
income into earnings.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

|(2) | The portion of the cumulative gain or loss on the derivative necessary to offset the cumulative change in expected future cash flows on the hedged transaction from inception of the
hedge less the derivatives gains or losses previously reclassified from accumulated other comprehensive income into earnings.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

A gain
or loss shall be recognized in earnings, as necessary, for any remaining gain or loss on the hedging derivative or to adjust other comprehensive income to the balance specified above. The ineffective portion would be the amount of change in fair
value of the hedge that is greater than the change in fair value of the hypothetical derivative on an absolute basis.

Relief of Other Comprehensive
Income Account (OCI)

OCI will be released into P&L as and when the hedged natural gas sales occur and the monthly contract settles. Amounts will be
cleared to the Income Statement utilizing a revenue account.
