15
equity, or under this Agreement to collect the unpaid amount of such Capital
Contribution, and if such amount or any portion thereof shall remain unpaid for
ten days after the date due, such unpaid amount shall bear interest at a rate
equal to the Interest Rate from the date due until paid.

2.05 Return of Capital Contribution. No Partner shall be entitled
to a return of any cash or property contributed to the capital of the
Partnership except as provided in Section 4.09 or Articles VII and XI;
provided, however, that if the Limited Partner shall have agreed to make
Optional Contributions but shall not have received statements pursuant to
Section 2.03 calling for the actual contribution of such amounts within six
months following the date of such agreement (or such other time as the General
Partner and the Limited Partner may agree at the time of the Limited Partner's
agreement to make such Optional Contributions), or if any amount so contributed
shall not have been spent within such six-month (or other) period, the Limited
Partner shall not be required to contribute any amount not already contributed
and the amounts already contributed but not so spent shall constitute "revenues
received by the Partnership during the immediately preceding calendar month"
for purposes of Section 7.01, and any such reduction or return shall constitute
a compromise under Section 17-502(b) of the Act.

2.06 Interest. No Partner shall be entitled to be paid interest on
its capital account or on Capital Contributions.

2.07 Certain Borrowings. Lease Operating Costs and Cost Overruns
shall be funded out of Revenues generated by the Partnership's Leasehold
Interests, to the extent that such Revenues are available therefor; provided,
however, at any time the Partnership shall not have sufficient cash available
to fund Lease Operating Costs and Cost Overruns, the General Partner shall
notify the Limited Partner of the need for funds and the time by which they
shall be needed. Before the time such funds are so needed, the Limited Partner,
at its sole option, may lend funds to the Partnership, or propose to third
parties that they make loans to the Partnership, to cover such needs, but in
any such case, the interest rate shall be lower than the General Partner's
average short-term borrowing rate. If the Limited Partner shall not make or
arrange for such loans by the time the funds shall be needed to pay Lease
Operating Costs or Cost Overruns, the General Partner may (a) advance such
funds for or on behalf of the Partnership, and each such advance shall
constitute a loan from the General Partner to the Partnership and shall bear
interest (on the basis of a 365-day year) from the date of the advance until
the date of repayment at the average short-term borrowing rate then being paid
by the General Partner, or (b) cause the Partnership to borrow such funds from
one or more third parties that are not Affiliates but only if such loan is (i)
unsecured or (ii) nonrecourse except as to Leasehold Interests on

-11-
16
which such funds shall be spent; provided, however, that the aggregate of any
and all of such funds borrowed by the Partnership as described in clauses (a)
or (b) of this sentence, shall not exceed $200,000. Such advances shall not be
considered as Capital Contributions. All advances shall be repaid out of the
next available funds of the Partnership, including Capital Contributions
received; provided, however, that if such advance is from a partner, any
amounts so payable shall be applied to amounts then due to the Partnership from
such Partner. The partners acknowledge their intent that, from time to time the
General Partner may, with the contemporaneous written consent of the Limited
Partner, cause the Partnership to borrow additional funds needed to fund Cost
Overruns, provided that the aggregate of such additional borrowings and
Distributable Net Revenues retained by the General Partner pursuant to the last
sentence of Section 7.01 hereof shall not exceed $700,000 at any one time.

2.08 Capital Accounts. A capital account shall be established and
maintained for each Partner. Except as specified in clauses (A) through (G)
below, each Partner's capital account shall be (a) increased by (i) the amount
of cash and the fair market value of all property contributed by such Partner
to the Partnership (net of any liabilities assumed by the Partnership on
account thereof or to which such property is subject at the time of such
acquisition), (ii) that Partner's allocable share of income and gain for
federal income tax purposes, including income and gain (other than Simulated
Gain) described in Treasury Regulation Section 1.704-l(b)(2)(iv)(g), but
excluding income and gain described in Treasury Regulation Section
1.704-1(b)(4)(i), (iii) that Partner's allocable share of Simulated Gain, and
(iv) that Partner's allocable share (determined by reference to its share of
the related proceeds of such items under the terms of this Agreement) of income
exempt from tax described in Section 705 (a)(1)(B) of the Code, and (b)
decreased by (i) the amount of cash and the fair market value of property
distributed to such Partner (net of liabilities assumed by the Partner or to
which the property is subject), (ii) that Partner's allocable share of losses
and other items of deduction for federal income tax purposes, including loss
and deduction (other than Simulated Loss) described in Treasury Regulation
Section 1.704-l(b)(2)(iv)(g), but excluding loss and deduction described in
Treasury Regulation Section 1.704-1(b)(4)(i), (iii) that Partner's allocable
share of Simulated Loss and Simulated Depletion, (iv) that Partner's al1ocable
share of expenditures described in Section 705(a)(2)(B) of the Code (determined
by reference to such Partner's share of the cost of such related items), and
(v) the amount of windfall profit tax withheld on such Partner's proportionate
share of income resulting from sales of crude oil. The definitions and rules
governing the maintenance and operation of the capital accounts and the
computation of the amounts to be charged and credited thereto are as follows:

-12-
17
(A) If the Carrying Value of any property contributed to
the Partnership is different from its adjusted basis, upon a sale or other
taxable disposition of such property the gain or loss resulting from such sale
or disposition with respect to which gain or loss is recognized for federal
income tax purposes shall be computed by reference to the Carrying Value of
such property, notwithstanding that the adjusted tax basis of such property
differs from its Carrying Value. If the Carrying Value of any distributed
property is different from its then adjusted basis on the books and records of
the Partnership, the gain or loss (including Simulated Gain or Simulated Loss)
that would have been realized if such properties had been sold and the cash
proceeds distributed to such Partner or Partners shall be charged or credited
to the capital accounts of the Partners in accordance with the preceding
sentence. In lieu of the depreciation, amortization and other cost recovery
deduction taken into account for federal income tax purposes there shall be
taken into account Depreciation as defined in Section 1.07.

(B) The allocation of basis pursuant to Section 3.02(f)
and amounts realized pursuant to clause (D) below to a Partner shall have no
effect on that Partner's capital account except as specified in clause (C)
below. Further, neither the deduction for depletion nor the taxable gain or
loss resulting upon the sale, abandonment, or other taxable disposition of an
oil or gas property (all as computed pursuant to Section 3.02(f)), shall be
charged or credited to any Partner's capital account, except to the extent and
in the manner provided in clause (C) below.

(x) The Partnership shall establish and maintain
books and records containing asset accounts representing the aggregate
adjusted depletable basis credited to the capital accounts of all
Partners in each oil or gas property (as defined in Section 614 of the
Code) at the time the property first begomes a property of the
Partnership (the "Simulated Basis"). The Simulated Basis for each
property shall be adjusted from time to time in the same manner as if
the Simulated Basis were the Partnership's adjusted basis in such
property to reflect (1) additions to basis and (2) Simulated
Depletion, as provided in clause (y) below; and the Simulated Basis,
as adjusted, shall be utilized to determine Simulated Gain or
Simulated Loss, as provided in clause (z) below.

(y) The Partnership shall compute a depletion
allowance ("Simulated Depletion") on each oil or gas property for each
taxable year based on the Simu-

-13-
18
lated Basis, as theretofore adjusted, in accordance with the
provisions of Treasury Regulation Section 1.704-1(b)(2)(iv)(k)(2).
Such Simulated Depletion allowance with respect to each oil or gas
property shall be allocated to the Partners, and shall reduce each
Partner's capital account, in the same proportion that the Partners
were allocated the adjusted basis of such property as provided in
Section 3.02(f). However, in no event shall the Partnership's
aggregate Simulated Depletion allowance with respect to an oil or gas
property exceed the Partnership's Simulated Basis of such property.

(z) The Partnership shall compute simulated gain
or loss attributable to the sale, abandonment, or other taxable
disposition of an oil or gas property based on the difference between
the amount realized from the disposition and the Simulated Basis of
such property, as theretofore adjusted. Any resulting gain ("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 disposition in excess of Simulated Basis is allocated to the
Partners under Section 2.08(D). Any resulting loss ("Simulated Loss")
shall be allocated to the Partners and shall reduce their capital
accounts in the same proportion that such Partners (or their
predecessors in interest) shall have been allocated the adjusted basis
of such property as provided in Section 3.02(f).

(D) Subject to the provisions of Section 2.08(A), for
purposes of determining each Partner's allocable share of the amount realized
from the sale or other taxable disposition of oil or gas properties (other than
oil, gas, or other hydrocarbon substances), the following steps shall be taken:
First, the portion of the amount realized that represents a recovery of the
Partnership's Simulated Basis, as theretofore adjusted to date, in each
property sold or disposed of shall be allocated to the Partners in the same
proportion as the Partners (or their predecessors in interest) shall have been
allocated adjusted basis with respect to that property under Section 3.02(f).
Second, any remaining portion of the amount realized shall then be allocated to
the Partners in such a way as to cause, to the maximum extent possible, the
total amount realized allocated to that Partner under this clause (D) to equal
that Partner's Sharing Ratio of the proceeds derived from such sale or other
disposition (including such Partner's Sharing Ratio of any proceeds from the
sale or disposition of tangible property associated with such oil or gas
property).

-14-
19
(E) In the event the Carrying Value of the Partnership
assets is adjusted in accordance with the provisions of Subparagraph (ii) under
the definition of "Carrying Value" contained in Section 1.07 hereof, the
capital accounts of all Partners shall be adjusted simultaneously to reflect
the aggregate net adjustment as if the Partnership recognized gain or loss
equal to the amount of such aggregate net adjustment.

(F) In all events, and notwithstanding anything contained
in this Agreement which might otherwise produce a conflicting result, capital
accounts shall be maintained in accordance with the provisions of Treasury
Regulation Section 1.704-1(b)(2)(iv) and Section 1.704-1(b)(4)(iv).

(G) In the event any interest in the partnership is
transferred in accordance with the terms of this Agreement, the transferee
shall succeed to the capital account of the transferor to the extent it relates
to the transferred interest, and to the extent such succession is necessary to
maintain the capital accounts in compliance with applicable Treasury
Regulations.

ARTICLE III.

COSTS, REVENUES AND ALLOCATIONS

3.01 Sharing of Costs and Revenues. All costs and revenues of the
Partnership shall be shared between the Partners in proportion to their
respective sharing ratios ("Sharing Ratios"). The Partners' Sharing Ratios
shall be as follows:

(a) Prior to Payout, all costs (other than interest
payable pursuant to Section 7.02) and revenues shall be shared:

General Partner 1%
Limited Partner 99%

(b) Interest payable pursuant to Section 7.02:

General Partner 100%
Limited Partner 0%

General Partner 25%
Limited Partner 75%

3.02 Allocations. Except as provided in Section 11.04, for
accounting and income tax purposes all items of Part-

-15-
20
nership income, gain, loss, deduction, and credit shall be allocated to the
Partners as follows:

(a) All items of income arising from the sale of oil,
gas, or other hydrocarbon substances and all other items of income or gain
other than those items described in Section 3.02(b), (c), (h), (k), (l) and (m)
shall be allocated to the Partners in accordance with the allocation of the
revenues giving rise to such income or gain;

(b) Gain or loss realized upon the sale, abandonment, or
other taxable disposition of all or part of any oil or gas property shall be
computed separately by the Partners in the same manner as depletion pursuant to
Section 3.02(f) and shall not be charged or credited to any Partner's capital
account, except to the extent and in the manner provided in Section 2.08(C)(2);

(c) Gain or loss realized upon the sale, abandonment, or
other taxable disposition of tangible property shall be allocated to the
Partners in accordance with their contributions to the unadjusted cost basis of
such tangible property;

(d) Cost recovery deductions with respect to tangible
property shall be allocated to the Partners in accordance with their respective
contributions to the unadjusted cost basis of such tangible property;

(e) If any depreciation, cost recovery, or intangible
drilling and development costs shall be recaptured as a result of the
disposition of any Partnership property, the character of the gain allocated
under other provisions of this Agreement shall be determined and allocated to
the Partners in such manner and in the proportion (to the maximum extent
possible) that the Partners that originally received allocations of cost
recovery and intangible drilling and development cost deductions attributable
to the assets disposed of shall recognize the ordinary income element of any
such gain so recognized;

(f) The deduction for depletion with respect to each
separate Partnership property (as defined in Section 614 of the Code) shall be
computed separately for each Partner rather than by the Partnership and shall
not be charged to any Partner's capital account; and for purposes of such
computation, each Partner shall be considered to own, and shall be allocated,
its proportionate share of the adjusted basis in each Partnership oil and gas
property as follows: the proportionate share of each Partner in the adjusted
basis of each Partnership property shall be such Partner's interest in the
Partnership capital with respect to that property, which shall be determined in
accordance with its Sharing Ratio (i) in the Partnership capital used to
acquire or provide capitalized improvements to such property if

-16-
21
the property shall be acquired or improved by the Partnership, or (ii) in the
adjusted basis of property if such property shall be contributed to the
Partnership; provided, however, that if the fair market value of such property
differs from its adjusted basis to the contributor immediately preceding such
contribution, the basis of such property shall be shared between the Partners
to take account of such variance in accordance with the principles of Section
704(c) of the Code; and the General Partner shall maintain separate records for
each Partner's share of the adjusted basis in each Partnership oil and gas
property and adjust each Partner's share of the adjusted basis in each such
property for any cost or percentage depletion allowable on such property and
use such adjusted basis in the computation of gain or loss on the disposition
of such property; provided, however, that the Limited Partner shall advise the
General Partner upon request by the General Partner of the Limited Partner's
adjusted basis on each oil and gas property of the partnership as computed in
this Section 3.02(f); and the amount of gain or loss to be recognized by a
Partner for income tax purposes as a result of the sale or other taxable
disposition of an oil or gas property shall be equal to the difference between
the amount realized from such sale or disposition allocated to such Partner,
pursuant to Section 2.08(D) and such Partner's adjusted basis in such property,
computed in the manner described above;

(g) Deductions with respect to Lease Operating Costs and
intangible drilling and development costs shall be allocated to the Partners in
accordance with their respective contributions to such costs;

(h) The consequent decrease in deduction or increase in
income resulting from any dry-hole or bottom-hole contribution obtained from a
third person in connection with the drilling of a Partnership Well shall be
allocated in the same manner as the costs of drilling such Partnership Well are
charged to the parties under this Agreement;

(i) All other losses, deductions, and credits not falling
within the foregoing provisions of this Section 3.02 shall be allocated to and
accounted for by each Partner in accordance with its respective contributions
to the costs that gave rise to the loss, deduction, or credit;

(j) If not otherwise provided for herein, income arising
from the receipt of property other than money shall be allocated to the
Partners in the same proportions as the proceeds of sale would be shared if the
property were sold immediately after receipt thereof by the Partnership;

(k) Notwithstanding the foregoing provisions of this
Section 3.02, no allocation of loss or deduction (other than an allocation of
nonrecourse deductions described in paragraph

-17-
22
3.02(l) below) shall be made to a Limited Partner to the extent such allocation
would cause or increase a deficit balance in such Limited Partner's capital
account. Such loss or deduction shall be allocated to the General Partner.

(l) Notwithstanding the foregoing provisions of this
Section 3.02, in the event there is a net decrease in Partnership "Minimum
Gain" during a Partnership taxable year, all Partners with a deficit capital
account balance at the end of such year (excluding from each Partner's deficit
capital account balance any amount that such Partner is obligated to restore
under Treasury Regulation Section 1.704-1(b)(2)(ii)(c), as well as any addition
thereto pursuant to the next to last sentence of Treasury Regulation
Section 1.704-1(b)(4)(iv)(f) computed with respect to the amount of Partnership
minimum gain after such net decrease) will be allocated, before any other
allocation is made under this Agreement of Partnership items for such taxable
year, items of income and gain for such year (and, if necessary, subsequent
years) in the amount and in the proportions needed to eliminate such deficit as
quickly as possible. For purposes of this Section 3.02(l), a Partner's capital
account shall be reduced for the items described in Treasury Regulation Section
1.704-1(b)(2)(ii)(d)(4), (5) and (6). In addition, for purposes of this Section
3.02(l), the amount of the Partnership's "Minimum Gain", and a Partner's share
thereof, shall be as determined under Treasury Regulation Section
1.704-1(b)(4)(iv);

(m) In the event any Partner unexpectedly receives any
adjustment, allocation or distribution described in Treasury Regulation Section
1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership income and gain shall
be specially allocated to such Partner in an amount and manner sufficient to
eliminate the deficit balance in such Partner's capital account created by such
adjustments, allocations, or distributions as quickly as possible; and

(n) Notwithstanding anything else herein provided to the
contrary, all items of income, gain, loss and deduction with respect to
property contributed to the Partnership shall, solely for tax purposes, be
allocated among the Partners so as to take account of the variation between the
basis of the property to the Partnership and its fair market value at the time
of contribution, in such manner as the General Partner determines comports with
the requirements of Section 704(c) of the Code and the Treasury Regulations
issued thereunder.

3.03 Limitation on Deductions. Notwithstanding any provision of
this Agreement to the contrary, in no event shall (a) the aggregate deductions
that may be claimed by the Partners as their distributive shares of Partnership
losses during the first two years of operation of the Partnership exceed the
sum of the capital contributions of the Partners to the Partnership, or

-18-
23
(b) the interest of the General Partner in any item of Partnership income,
gain, loss, deduction, expense, or credit ever be less than 1% thereof.

3.04 Lender as Partner. Without limiting the provisions of Section
4.04(a), no creditor that makes a nonrecourse loan to the Partnership may have
or acquire at any time as a result of making the loan any direct or indirect
interest in the profits, capital, or property of the Partnership unless and to
the extent it is as a secured creditor.

3.05 Windfall Profit Taxes. For windfall profit tax purposes, the
Partnership's economic interest in any crude oil produced by it shall be
allocated between the Partners on the basis of each Partner's proportionate
share of income from such crude oil, and such Partner to whom such crude oil or
the income therefrom is allocated shall be treated as the producer of such
crude oil in accordance with the provisions of Section 4996(a)(1)(C) of the
Code. The capital account of each Partner shall be charged with the amount of
windfall profit tax withheld on such Partner's proportionate share of income
resulting from sales of such crude oil. The General Partner shall keep records
of all documents, material, and information necessary for the determination of
windfall profit taxes and shall provide such records to the Partners as are
necessary to enable each Partner timely to determine its windfall profit tax
liability and to prepare and file any windfall profit tax returns or claims for
credit or refund of windfall profit taxes due with respect to any Partnership
production.

ARTICLE IV.

taking such action and provided further that the General Partner shall not, and
shall not permit any Affiliate to, file or otherwise instigate, directly or
indirectly, proceedings leading to any such order;

(h) To execute and deliver all checks, drafts,

Persons dealing with the Partnership shall be entitled to rely conclusively on
the specific authority and express power of the General Partner as set forth in
this Agreement.

4.03 Operating Agreements. The General Partner may cause the
Partnership to enter into one or more Operating Agreements, which Operating
Agreements shall govern the exploration, development, and operation of the
Leasehold Interests in which the Partnership owns an interest. Except for
Operating Agreements applicable to Leasehold Interests at the time the General
Partner, an Affiliate, or the Partnership first shall acquire an interest
therein, each such Operating Agreement (a) shall be on terms usual and
customary in the oil and gas industry, (b) to the extent reasonably practicable
shall be on the A.A.P.L. Form 610 (1977 or 1982 version) Model Form Operating
Agreement, and (c) shall not include "non-consent penalties" exceeding 400% or
permission for the operator to make expenditures in excess of $25,000 without
the consent of the co-owners. The General Partner or an Affiliate may be the
operator under any Operating Agreement even though it owns no interest in the
Leasehold Interests governed thereby.

4.04 Limitations on General Partner's Powers. Notwithstanding any
other provisions of this Agreement to the contrary, the General Partner shall
not have the power or authority to, and shall not, do, perform, or authorize
any of the following for the Partnership without having first obtained the
consent in writing of all of the Partners:

(a) Borrow any money in the name or on behalf of the
Partnership except as provided in Section 2.07;

(b) Mortgage, pledge, assign in trust, or otherwise
encumber any Partnership property, or to assign any monies owing or to be owing

(c) Guarantee in the name or on behalf of the Partnership
the payment of money or the performance of any contract or other obligation of
any person, firm, or corporation, other than of the Partnership;

-21-
26
(d) Sell, assign, farm out, abandon, or otherwise dispose
of, or take any action that will lead to (or fail to take action that will
prevent) the release or disposition of, the Partnership's interest in any
Leasehold Interest on which a Partnership Well that is producing or capable of
producing oil or gas in paying quantities shall be located; provided, however,
that after a Partnership Well that previously shall have been producing shall
have ceased production, or shall have been plugged, the General Partner may
sell, assign, farm out, abandon, or otherwise dispose of, or take an action
that will lead to (or fail to take action that will prevent) the disposition
of, the Leasehold Interests in which the Partnership owns an interest with
respect to such well, but if the General Partner or an Affiliate owns an
interest for its own account in the same Leasehold Interests, the General
Partner shall have the right to make such disposition or to take (or fail to
take) such action for the Partnership if and only if it does so on the same
terms and conditions as the General Partner or such Affiliate shall dispose of,
or take action that will lead to (or fail to take action that will prevent) the
release or disposition of, such interest it owns for its own account; and
provided further that, if the same constitutes a permitted election under a
forced pooling, unitization, or communitization order of a governmental agency
having jurisdiction over such Leasehold Interest, the General Partner may cause
the Partnership to farm out such Leasehold Interest to a person other than the
General Partner or an Affiliate on terms usual and customary in the oil and gas
industry, following five Business Days' notice to the Limited Partner;

(e) Cause the Partnership to purchase any Leasehold
Interest unless the Limited Partner shall have agreed to contribute its Sharing
Ratio of the costs of such purchase pursuant to Sections 2.02 and 9.02;

(f) Cause the Partnership to participate in any Optional
Operation unless the Limited Partner shall have agreed to contribute its
Sharing Ratio of the costs thereof pursuant to Sections 2.02 and 9.01, except
as otherwise provided in the last sentence of Section 9.01;

(g) Take any action that would lead any third party
reasonably to believe that the Limited Partner is a general partner of the

4.05 Performance of Obligations as Operator. The General Partner as
operator under any Operating Agreement pursuant to which it is operator shall
perform all of its obligations and duties thereunder in accordance with all of
the terms and provisions thereof.

-22-
27
4.06 Insurance. The General Partner shall carry and maintain in
force and effect on behalf of the Partnership (either directly or through
Operating Agreements) the insurance coverages shown on Exhibit B from the date
hereof and as long hereafter as the Partnership remains in existence, or until
the Limited Partner shall notify the General Partner that it no longer desires
for the Partnership to be covered by such insurance. The General Partner shall
be free to change insurance carriers from time to time; provided, however, that
the coverages of the policies, their limits, and the financial standing of the
insurance carriers at all times shall not be diminished from the coverages and
limits of the policies and the financial standing of the insurance carriers
shown on Exhibit B. The Partnership and the Limited Partner shall be named as
additional insureds or loss payees on such policies, as the case may be. Each
such insurance policy shall include a provision requiring the issuer of such
insurance policy to give the Limited Partner 30 days' prior written notice of
any change, alteration, cancellation, or termination of any such policy. Upon
request by the Limited Partner, the General Partner shall cause the carrier of
any such insurance to provide the Limited Partner a certificate of insurance or
other evidence of such coverage satisfactory to the Limited Partner.

4.07 Fiduciary Relationship. The General Partner shall have a
fiduciary duty and obligation to the Limited Partner to conduct the affairs of
the Partnership in the best interests of the Partnership and the mutual best
interests of its Partners, including, without limitation, the safekeeping and
use of all Partnership funds and assets and the use thereof for the benefit of
the Partnership. The General Partner at all times shall act with integrity and
in good faith and utilize its best efforts in all activities relating to the
conduct of the business of the Partnership and in resolving conflicts of
interest. During the existence of the Partnership, the General Partner shall
devote such time and effort to the Partnership business and operations as shall
be necessary to promote fully the interests of the Partnership and the mutual
best interests of the Partners; however, it is specifically understood and
agreed that the General Partner shall not be required to devote full time to
Partnership business, and (subject to the other express provisions hereof) the
General Partner and Affiliates at any time and from time to time may engage in
and possess an interest in other business ventures of any and every type and
description, independently or with others, including, without limitation, the
ownership, acquisition, exploration, development, operation, and management of
oil and gas properties, oil and gas drilling programs, and partnerships similar
to this Partnership (but the General Partner promptly shall notify the Limited
Partner of any such action involving Leasehold Interests in which the
Partnership also owns an interest unless otherwise expressly provided herein);
and

-23-
28
(subject to the other express provisions hereof) neither the Partnership nor
the Limited Partner by virtue of this Agreement shall have any right, title, or
interest in or to such independent ventures. In addition to the Management Fee,

arrangement proposing any Optional Operation, or upon the General Partner's
giving such a notice (either for itself or for the Partnership) to third
parties on account of an interest in any Leasehold Interest in which the
Partnership owns an interest, the General Partner shall notify the Limited
Partner of the same; provided, however, that if the Election Period (as
hereinafter defined) shall be less than thirty days and if the General Partner
shall give such notice, the General Partner shall notify the Limited Partner of
the same at least 40 days prior to the expiration of such Election Period. Such
notice shall include a copy of any written notice from any third party or by
the

-32-
37
General Partner to any third party proposing such Optional Operation, a
statement of the time by which the Partnership shall be obliged contractually
to notify the operator of the applicable Leasehold Interest or other
appropriate person whether the Partnership elects to participate in such
operation (the "Election Period"), the consequences of failing to notify such
person within such period, a summary of the pertinent geological and
engineering data and financial projections regarding the proposed operation, a
statement (the "Statement") whether the General Partner recommends
participation in such Optional Operation and whether the General Partner has
agreed or intends to agree to participate with respect to any interest it owns
for its own account in the Leasehold Interests affected, such title information
as the Limited Partner reasonably may request, and a statement that the Limited
Partner's failure to respond at least 10 days prior to the expiration of the
Election Period shall be deemed to mean it elects not to make additional
contributions to the capital of the Partnership to fund such Optional
Operation, provided, if the Statement from the General Partner recommends that
the Partnership participate in the Optional Operation in question, such
Statement shall also include a cash purchase offer from the General Partner to
the Partnership for the Partnership's interest in the well bore, and well bore
only, of the Partnership Well (whether existing or to be drilled) which is the
subject of such Optional Operation setting forth the terms of such offer
including, without limitation, the amount which the General Partner offers to
pay for such interest.

If the Statement from the General Partner recommends that the
Partnership not participate in the Optional Operation in question, the
Partnership will not participate in such Optional Operation. Instead, the
Partnership will, subject to the other provisions of this Agreement including,
without limitation, Sections 4.04 and 6.01 hereof, follow the General Partner's
recommendation (which shall be contained in such Statement) to (i) farm-out to
a third party, which is not an Affiliate of the General Partner, the
Partnership's interest in the well bore, and well bore only, of the Partnership
Well (whether existing or to be drilled) which is the subject of the proposed
Optional Operation, (ii) sell such interest to a third party which is not an
Affiliate of the General Partner, or (iii) be subject to the non-consent
provisions of the applicable Operating Agreement.

If the Statement from the General Partner recommends that the
Partnership participate in the Optional Operation in question, the Limited
Partner shall have the right (but not the obligation), at its sole option, to
make additional contributions of capital to the Partnership to fund such
Optional Operation, which election may be exercised by the Limited Partners'
notifying the General Partner at least 10 days before the expiration of the
Election Period whether it elects to make such Optional Contributions;
provided, however, the Limited Partner's failure

-33-
38
to notify the General Partner of its election at least 10 days before the
expiration of the Election Period shall be deemed to mean it has elected not to
make such Optional Contributions. If the Limited Partner elects, or is deemed
to elect, not to make additional contributions to the capital of the
Partnership to fund the proposed Optional Operation, then the General Partner
shall not cause the Partnership to participate in such Optional Operation, and
shall either (i) cause the Partnership to give all notices, make such
elections, and take all such further actions as may be necessary to prevent the
Partnership from becoming obligated to so participate, or (ii) farm-out to a
third party, which is not an affiliate of the General Partner, the
Partnership's interest in the Partnership Well which is the subject of the
proposed Optional Operation; provided, however, if the Limited Partner consents
in writing at least 10 days before the expiration of the Election Period, the
Partnership may accept the General Partner's purchase offer and sell its
interest in the Partnership Well in question to the General Partner. Anything
to the contrary contained in this Section 9.01 notwithstanding, but subject to
the remainder of this sentence, the General Partner may cause the Partnership
to participate in an Optional Operation notwithstanding the Limited Partner's
election not to make Optional Contributions with respect thereto, to the extent
that Distributable Net Revenues retained by the Partnership pursuant to the
last sentence of Section 7.01 and borrowings made as contemplated by the last
sentence of Section 2.07 hereof, are sufficient therefor and for all other
expenses of the Partnership.

9.02 Acquisition of Leasehold Interests. Whenever the General
Partner receives a request or proposal under any agreement or arrangement to
which the Partnership is a party for the Partnership to acquire Leasehold
Interests that are covered by an Operating Agreement, or at any other time that
the General Partner desires to propose that the Partnership acquire additional
Leasehold Interests that are covered by an Operating Agreement, the General
Partner may (but shall not be obligated to) propose that the Partnership
acquire Leasehold Interests by giving notice thereof to the Limited Partner.
Such notice shall include copies of proposed acquisition documents, a statement
of the proposed Acquisition Amount therefor, a summary of the pertinent
geological, geophysical, and engineering data, financial projections regarding
the proposed acquisition, title information (if such Leasehold Interests then
shall be producing) a summary of any existing reserve report, if available, (if
such notice shall be from the General Partner), and a statement whether the
General Partner recommends such acquisition and whether the General Partner has
agreed or intends to agree to acquire an interest in such Leasehold Interest
for its own account. The Limited Partner shall have the right (but not the
obligation), at its sole option, to make additional contributions to the
capital of the Partnership therefor, and the Limited Partner shall notify

-34-
39
the General Partner whether it elects to make such contributions; provided,
however, that the Limited Partner's failure to notify the General Partner of
its election within 30 Business Days after its receipt of the General Partner's
notice shall be deemed to mean it has elected not to make such contributions.
If the Limited Partner elects not to make such contributions, or if the Limited
Partner has not made its election before the Partnership is required to notify
any party as to the Partnership's decision, or if the General Partner does not
give notice of the proposed acquisition to the Limited Partner, then the
General Partner shall not cause the Partnership to acquire such Leasehold
Interests, and shall cause the Partnership to give all notices, make such
elections and to take all such other actions as may be necessary to prevent the
Partnership from becoming obligated to so acquire same.

9.03 Limitation. Under no circumstances shall the Limited Partner
be obligated by this Article IX to contribute more to an acquisition and/or
operation, as applicable, than the maximum amount of such contributions, or
upon any schedule other than the schedule for such contributions, to which it
agrees in its notice to the General Partner of its election to make such
contributions pursuant to this Article IX.

11.02 Covenant Not to Withdraw. Except for causing a dissolution
pursuant to Section 11.01(c), the General Partner covenants and agrees not to
withdraw voluntarily from the Partnership, whether directly or by dissolution
or any other voluntary act. If the General Partner shall violate such covenant
and agreement, the withdrawal shall be effective for purposes of Section 11.01
to cause a dissolution of the Partnership, but the General Partner shall be
liable to the Limited Partner for all damages suffered or incurred by it as a
result of such withdrawal. For purposes of this Agreement, a "voluntary
withdrawal" by the General Partner shall consist of any of the applicable
events set forth in Section 17-402 of the Act other than those described in
subparagraphs (3) and (5) thereof.

11.03 Continuation and Reconstitution. Upon the occurrence of any
event that would cause a dissolution pursuant to Section 11.01 that also
constitutes an "event of withdrawal of a general partner" as defined in Section
17-101(3) of the Act, the Partnership shall, notwithstanding anything to the
contrary contained in Section 17-801(3) of the Act, be dissolved but shall not
be wound up by reason of such event if, within 90 days after such event, the
Limited Partner agrees in writing to continue the business of and reconstitute
the Partnership and to the appointment of, effective as of the date of such
event, a new general partner of the Partnership, which shall be admitted as the
general partner and shall succeed to the rights and duties of the General
Partner hereunder. In the event the Partnership shall be so continued and
reconstituted, the Partnership shall distribute to the General Partner an
amount equal to the amount that would have been distributed to the General
Partner pursuant to Section 11.04 had the Partnership been liquidated at that
time. The General Partner's consent shall not be required for any continuation
and reconstitution hereunder or for the designation of the new general partner
hereunder. The Limited Partner's right to elect to continue the business of and
reconstitute the Partnership may be exercised at its sole option, and its
failure to exercise such right shall not relieve the General Partner of any of
its obligations, including, without limitation, those arising pursuant to
Section 11.02.

11.04 Liquidation and Termination. Upon dissolution of the
Partnership, the General 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 Partnership shall be dissolved pursuant to the
provisions of Section 11.01(c), (e), or, to the extent such event affects the
General Partner only, (g) or Section 11.02, the liquidator shall be a person
selected in writing by the Limited Partner. The liquidator shall proceed
diligently to wind up the affairs of the Partnership and make final
distribution as provided herein. Once

-38-
43
liquidation shall be completed a final accounting shall be made of the affairs
of the Partnership and of each Partner from the date of the last accounting. In
the event the Partnership shall be dissolved and liquidated pursuant to the
provisions of Section 11.01(c), (e), or, to the extent such affects the General
Partner only, (g) or Section 11.02, all costs associated with liquidation of
the Partnership shall be borne by the General Partner; otherwise, the costs of
liquidation shall be borne as a Partnership expense. Until final distribution,
the liquidator shall continue to operate the Partnership properties with all of
the power and authority of the General Partner. The steps to be accomplished by
the liquidator are as follows:

(a) As promptly as possible after dissolution and again
after final liquidation, the liquidator shall cause a proper accounting to be
made by the Certified Public Accountants of the Partnership's assets,
liabilities, and operations through the last day of the calendar month in which
the dissolution shall occur or the final liquidation shall be completed, as
appropriate;

(b) The liquidator shall pay all of the debts and
liabilities of the Partnership (including all expenses incurred in liquidation
and any advances made by the Partners pursuant to Section 2.07) or otherwise
make adequate provision therefor (including, without limitation, the
establishment of a cash escrow fund for contingent liabilities in such amount
and for such term as the liquidator may reasonably determine); and

(i) If all Partners consent, selected Partnership
property may be sold, and any resulting gain or loss (including
Simulated Gain or Simulated Loss) from each sale shall be computed and
allocated to the capital accounts of the Partners as provided in
Sections 2.08 and 3.02; provided, however, that any interest in any
Leasehold Interest contributed by a Partner for which such Partner
shall not yet have received credit as required by Section 2.08, shall
be reassigned to such Partner;

(ii) With respect to any properties of the
Partnership not sold pursuant to clause (i) above, the fair market
value of such properties shall be determined and the unrealized gain
or loss (including unrealized Simulated Gain or Simulated Loss) that
would have been realized if the sale of all such properties at their
fair market values had occurred shall be charged or credited to the
capital accounts of the

-39-
44
Partners above as if such properties had been actually sold;

(iii) After the allocations of gain or loss
(including Simulated Gain or Simulated Loss) required by clauses (i)
and (ii) above shall have been credited or debited, as the case may
be, to the capital accounts of the Partners, the balances of the
capital accounts of the Partners shall be determined. If the General
Partner has a deficit balance in its capital account, it shall restore
the amount of such deficit balance to the Partnership within 90 days
and thereafter, the capital accounts of all Partners shall be
satisfied in full. In the event cash proceeds or property of
sufficient value are unavailable to satisfy the capital accounts of
the Partners, distribution shall be made to the Partners in proportion
to the ratio of their positive capital accounts.

All assignments made under the provisions of this Section 11.04 shall be made
in a form acceptable to the Partnership and assignee and shall be made subject
to the liability of each assignee for costs, expenses, and liabilities
theretofore incurred or for which the Partnership shall have committed prior to
the date of termination and such costs, expenses, and liabilities shall be
allocated to such assignee pursuant to this Section 11.04. The distribution of
cash and/or property to a Limited Partner in accordance with the provisions of
this Section 11.04 shall constitute a complete return to the Limited Partner of
its Capital Contributions and a complete distribution to the Limited Partner of
its interest in the Partnership and all the Partnership's property.

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