                economic and operating conditions, i.e., prices and costs as of
                the date the estimate is made. Prices include consideration of
                changes in existing prices provided only by contractual

                (i)     Reservoirs are considered proved if economic
                        producibility is supported by either actual production
                        or conclusive formation test. The area of a reservoir
                        considered proved includes:

                                drilled, but which can be reasonably judged as
                                economically productive on the basis of
                                available geological and engineering data.

                        In the absence of information on fluid contacts, the
                        lowest known structural occurrence of hydrocarbons
                        controls the lower proved limit of the reservoir.

                (ii)    Reserves which can be produced economically through
                        application of improved recovery techniques (such as
                        fluid injection) are included in the "proved"
                        classification when successful testing by a pilot
                        project, or the operation of an installed program in the
                        reservoir, provides support for the engineering analysis
                        on which the project or program was based.

                (iii)   Estimates of proved reserves do not include the
                        following:

                        (a)     oil that may become available from known
                                reservoirs but is classified separately as
                                "indicated additional reserves";

                        (b)     crude oil, natural gas, and natural gas liquids,
                                the recovery of which is subject to reasonable
                                doubt because of uncertainty as to geology,
                                reservoir characteristics, or economic factors;

                        (c)     crude oil, natural gas, and natural gas liquids,
                                that may occur in undrilled prospects; and

                        (d)     crude oil, natural gas, and natural gas liquids,
                                that may be recovered from oil shales, coal,
                                gilsonite and other such sources.

        52.     "Proved Undeveloped Reserves" means reserves that are expected
                to be recovered from either:

                (i)     new wells on undrilled acreage; or

                (ii)    from existing wells where a relatively major expenditure
                        is required for recompletion.

                Reserves on undrilled acreage shall be limited to those drilling
                units offsetting productive units that are reasonably certain of
                production when drilled. Proved reserves for other undrilled
                units can be claimed only where it can be demonstrated with
                certainty that there is continuity of production from the
                existing productive formation. Under no circumstances should
                estimates for proved undeveloped reserves be attributable to any
                acreage for which an application of fluid injection or other
                improved recovery technique is contemplated, unless such
                techniques have been proved effective by actual tests in the
                area and in the same reservoir.

        53.     "Roll-Up" means a transaction involving the acquisition, merger,
                conversion or consolidation, either directly or indirectly, of

                        Association of Securities Dealers Automated Quotation
                        National Market System; or

                (ii)    a transaction involving the conversion to corporate,
                        trust or association form of only the Partnership if, as
                        a consequence of the transaction, there will be no
                        significant adverse change in any of the following:

                (ii)    whenever the context so requires, the term "sponsor"

                natural gas and oil wells which are generally accepted as
                capital expenditures under the Code. This includes all of the
                following:

                                       10

serve as an agreement by the Participant to be bound by each and every term of
this Agreement.

General Partner, as a general partner and not as a Participant, shall:

later than December 31, 2004.

3.03(b)(2). MANAGING GENERAL PARTNER'S OPTIONAL ADDITIONAL SUBSCRIPTION. In

provisions of Section 3.03(a) and its subsections up to the minimum
subscriptions which are required under Section 3.03(c)(2) for the Partnership to
begin operations, and, subject to the limitations on voting rights set forth in
Section 4.03(c)(3), to that extent shall be deemed a Participant in the
Partnership for all purposes under this Agreement.

3.03(b)(3). EFFECT OF AND EVIDENCING SUBSCRIPTION. The Managing General Partner

        (i)     evidences the Managing General Partner's required subscription
                under Section 3.03(b)(1); and

        (ii)    may be amended to reflect the amount of any optional
                subscription under Section 3.03(b)(2).

Execution of the Managing General Partner Signature Page serves as an agreement
by the Managing General Partner to be bound by each and every term of this
Agreement.

3.03(c). MAXIMUM AND MINIMUM NUMBER OF UNITS.

3.03(c)(1). MAXIMUM NUMBER OF UNITS. The maximum number of Units may not exceed

the subscription discounts permitted under Section 3.03(a)(1). Notwithstanding
the foregoing, the maximum number of Units in both Atlas America Series
25-2004(A) L.P. and Atlas America Series 25-2004(B) L.P., in the aggregate,
shall not exceed 2,400 Units.

3.03(c)(2). MINIMUM NUMBER OF UNITS. The minimum number of Units shall equal at
least 40 Units, but in any event not less than that number of Units which
provides the Partnership with cash subscription proceeds of $1,000,000,
excluding the subscription discounts permitted under Section 3.03(a)(1).
Pursuant to Section 3.03(b)(2), the Managing General Partner, its officers,
directors, and Affiliates may purchase the number of Units required to satisfy
the minimum subscription proceeds required under Section 3.03(c)(1) to the
extent paid in cash and after the discounts permitted under Section 3.03(a)(1).

If at the Offering Termination Date the minimum number of Units has not been
received and accepted, then all monies deposited by subscribers shall be
promptly returned to them. They shall receive interest earned on their
subscription proceeds from the date the monies were deposited in escrow through
the date of refund.

The Partnership may break escrow and begin its drilling activities in the
Managing General Partner's sole discretion on receipt of the minimum
subscription proceeds. If a subscription is received before the distribution of
a Supplement to the Private Placement Memorandum which describes the proposed
prospects as discussed in "Terms of the Offering" and "Proposed Activities" in
the Private Placement Memorandum, then the subscriber must reaffirm his
subscription before his subscription is accepted or his subscription proceeds
are included in the minimum subscription proceeds required to break escrow.

3.03(d). ACCEPTANCE OF SUBSCRIPTIONS.

                less than 25% of all Capital Contributions to the Partnership;
                and

        (ii)    maintain a minimum Capital Account balance equal to not less
                than 1% of total positive Capital Account balances for the

        (ii)    the liquidation of the Managing General Partner's interest in
                the Partnership.

This shall be determined after taking into account all adjustments for the
Partnership's taxable year during which the liquidation occurs, other than
adjustments made pursuant to this requirement, by the end of the taxable year in
which its interest in the Partnership is liquidated or, if later, within 90 days
after the date of the liquidation.

                                       13


3.04(c). INTEREST FOR CONTRIBUTIONS. The interest of the Managing General
Partner, as Managing General Partner and not as a Participant in the capital and

account after the minimum number of Units have been received as provided in
Section 3.06(b), up until the Offering Termination Date at a rate of the greater
of 6% per annum or the market rate paid by National City Bank of Philadelphia.

If the amount of interest paid by National City Bank of Pennsylvania is less
than 6% per annum, then the difference shall be paid by the Managing General
Partner.

3.05(b)(2). ADDITIONAL REQUIRED CAPITAL CONTRIBUTIONS OF THE INVESTOR GENERAL
PARTNERS. Investor General Partners must make Capital Contributions to the
Partnership when called by the Managing General Partner, in addition to their
subscriptions, for their pro rata share of any Partnership obligations and
liabilities which are recourse to the Investor General Partners and are
represented by their ownership of Units before the conversion of Investor
General Units to Limited Partner Units under Section 6.01(b).

3.05(b)(3). DEFAULT PROVISIONS. The failure of an Investor General Partner to
timely make a required additional Capital Contribution under this section
results in his personal liability to the other Investor General Partners for the
amount in default. The remaining Investor General Partners, in proportion to
their respective number of Units, must pay the defaulting Investor General
Partner's share of Partnership liabilities and obligations. In that event, the
remaining Investor General Partners:

        (i)     shall have a first and preferred lien on the defaulting Investor
                General Partner's interest in the Partnership to secure payment
                of the amount in default plus interest at the legal rate;

        (ii)    shall be entitled to receive 100% of the defaulting Investor
                General Partner's cash distributions, in proportion to their
                respective number of Units, until the amount in default is
                recovered in full plus interest at the legal rate; and

        (iii)   may commence legal action to collect the amount due plus
                interest at the legal rate.

3.06. PARTNERSHIP FUNDS.

3.06(a). FIDUCIARY DUTY. The Managing General Partner has a fiduciary
responsibility for the safekeeping and use of all funds and assets of the
Partnership, whether or not in the Managing General Partner's possession or
control. The Managing General Partner shall not employ, or permit another to
employ, the funds and assets in any manner except for the exclusive benefit of
the Partnership.

3.06(b). SPECIAL ACCOUNT AFTER THE RECEIPT OF THE MINIMUM PARTNERSHIP
SUBSCRIPTIONS. Following the receipt of the minimum number of Units and breaking
escrow, the funds of the Partnership shall be held in a separate
interest-bearing account maintained for the Partnership and shall not be
commingled with funds of any other entity.

                subscription proceeds which are a necessary and incidental part
                of a property acquisition transaction; and

        (v)     investments in entities established solely to limit the
                Partnership's liabilities associated with the ownership or
                operation of property or equipment, provided that duplicative
                fees and expenses shall be prohibited.

3.06(c)(2). PERMISSIBLE INVESTMENTS BEFORE INVESTMENT IN PARTNERSHIP ACTIVITIES.
After the Initial Closing Date and until proceeds from the offering are invested
in the Partnership's operations, the proceeds may be temporarily invested in
income producing short-term, highly liquid investments, in which there is
appropriate safety of principal, such as U.S. Treasury Bills.

                Contribution set forth in Section 3.03(b)(1) at the Cost of the
                Lease, unless the Managing General Partner has cause to believe
                that Cost is materially more than

                                       15


        the fair market value of the property, in which case the credit for the
        contribution must be made at a price not in excess of the fair market
        value.

A determination of fair market value must be:

        (i)     supported by an appraisal from an Independent Expert; and

IN THE REMAINDER INTERESTS. Subject to the provisions of Section 4.03(d) and its

interest in the Lease may be held by the Managing General Partner or its
Affiliates. They may either:

                or

Affiliates to the exclusion of the Partnership.

4.01(a)(6). NO BREACH OF DUTY. Subject to the provisions of Section 4.03 and its
subsections, acquisition of Leases from the Managing General Partner, the
Operator or their Affiliates shall not be considered a breach of any obligation
owed by them to the Partnership or the Participants.

4.03(b)(6). REQUIRED LENGTH OF TIME TO HOLD RECORDS. The Managing General
Partner must maintain and preserve during the term of the Partnership and for
six years thereafter all accounts, books and other relevant documents which
include:

        (i)     a record that a Participant meets the suitability standards
                established in connection with an investment in the Partnership;
                and

        (ii)    any appraisal of the fair market value of the Leases as set
                forth in Section 4.01(a)(4) or fair market value of any
                producing property as set forth in Section 4.03(d)(3).

                                       21


4.03(c). MEETINGS OF PARTICIPANTS.

4.03(c)(1). PROCEDURE FOR A PARTICIPANT MEETING.

4.03(c)(1)(a). MEETINGS MAY BE CALLED BY MANAGING GENERAL PARTNER OR
PARTICIPANTS. Meetings of the Participants may be called as follows:

        (i)     by the Managing General Partner; or

        (ii)    by Participants whose Units equal 10% or more of the total Units
                for any matters for which Participants may vote.

The call for a meeting by Participants shall be deemed to have been made on
receipt by the Managing General Partner of a written request from holders of the
requisite percentage of Units stating the purpose(s) of the meeting.

4.03(c)(1)(b). NOTICE REQUIREMENT. The Managing General Partner shall deposit in
the United States mail within 15 days after the receipt of the request, written
notice to all Participants of the meeting and the purpose of the meeting. The
meeting shall be held on a date not less than 30 days nor more than 60 days
after the date of the mailing of the notice, at a reasonable time and place.

Notwithstanding the foregoing, the date for notice of the meeting may be
extended for a period of up to 60 days if, in the opinion of the Managing
General Partner, the additional time is necessary to permit preparation of proxy
or information statements or other documents required to be delivered in
connection with the meeting by the SEC or other regulatory authorities.

4.03(c)(1)(c). MAY VOTE BY PROXY. Participants shall have the right to vote at
any Participant meeting either:

        (i)     in person; or

        (ii)    by proxy.

4.03(c)(2). SPECIAL VOTING RIGHTS. At the request of Participants whose Units
equal 10% or more of the total Units, the Managing General Partner shall call
for a vote by Participants. Each Unit is entitled to one vote on all matters,
and each fractional Unit is entitled to that fraction of one vote equal to the
fractional interest in the Unit. Participants whose Units equal a majority of
the total Units may, without the concurrence of the Managing General Partner or
its Affiliates, vote to:

        (i)     dissolve the Partnership;

        (ii)    remove the Managing General Partner and elect a new Managing
                General Partner;

        (iii)   elect a new Managing General Partner if the Managing General
                Partner elects to withdraw from the Partnership;

        (iv)    remove the Operator and elect a new Operator;

        (v)     approve or disapprove the sale of all or substantially all of
                the assets of the Partnership;

        (vi)    cancel any contract for services with the Managing General
                Partner, the Operator, or their Affiliates that is not described
                in the Private Placement Memorandum or this Agreement without
                penalty on 60 days notice; and

        (vii)   amend this Agreement; provided however:

                (a)     any amendment may not increase the duties or liabilities
                        of any Participant or the Managing General Partner or
                        increase or decrease the profit or loss sharing or
                        required Capital Contribution of any

                                       22


                        Participant or the Managing General Partner without the
                        approval of the Participant or the Managing General
                        Partner; and

                (b)     any amendment may not affect the classification of
                        Partnership income and loss for federal income tax
                        purposes without the unanimous approval of all
                        Participants.

4.03(c)(3). RESTRICTIONS ON MANAGING GENERAL PARTNER'S VOTING RIGHTS. With
respect to Units owned by the Managing General Partner or its Affiliates, the
Managing General Partner and its Affiliates may vote or consent on all matters
other than the matters set forth in Section 4.03(c)(2)(ii) and (iv) above.

In determining the requisite percentage in interest of Units necessary to
approve any Partnership matter on which the Managing General Partner and its
Affiliates may not vote or consent, any Units owned by the Managing General
Partner and its Affiliates shall not be included.

4.03(c)(4). RESTRICTIONS ON LIMITED PARTNER VOTING RIGHTS. The exercise by the
Limited Partners of the rights granted Participants under Section 4.03(c),
except for the special voting rights granted Participants under Section
4.03(c)(2), shall be subject to the prior legal determination that the grant or
exercise of the powers will not adversely affect the limited liability of
Limited Partners. Notwithstanding the foregoing, if in the opinion of counsel to
the Partnership the legal determination is not necessary under Delaware law to
maintain the limited liability of the Limited Partners, then it shall not be
required. A legal determination under this paragraph may be made either pursuant
to:

        (i)     an opinion of counsel, the counsel being independent of the
                Partnership and selected on the vote of Limited Partners whose
                Units equal a majority of the total Units held by Limited
                Partners; or

        (ii)    a declaratory judgment issued by a court of competent
                jurisdiction.

The Investor General Partners may exercise the rights granted to the
Participants whether or not the Limited Partners can participate in the vote if
the Investor General Partners represent the requisite percentage of Units
necessary to take the action.

4.03(d). TRANSACTIONS WITH THE MANAGING GENERAL PARTNER.

4.03(d)(1). TRANSFER OF EQUAL PROPORTIONATE INTEREST. When the Managing General
Partner or an Affiliate (excluding another Program in which the interest of the
Managing General Partner or its Affiliates is substantially similar to or less
than their interest in the Partnership) sells, transfers or conveys any natural
gas, oil or other mineral interests or property to the Partnership, it must, at
the same time, sell, transfer or convey to the Partnership an equal
proportionate interest in all its other property in the same Prospect. Each
Prospect shall consist of the drilling or spacing unit on which the well will be
drilled by the Partnership, which is the minimum area permitted by state law or
local practice on which one well may be drilled.

Additionally, for a period of five years after the drilling of the Partnership
Well neither the Managing General Partner nor its Affiliates may drill any well:

        (i)     in the Clinton/Medina geological formation within 1,650 feet of
                an existing Partnership Well in Pennsylvania or within 1,000
                feet of an existing Partnership Well in Ohio; or

        (ii)    in the Mississippian/Upper Devonian Sandstone reservoirs in
                Fayette County and Greene County, Pennsylvania within at least
                1,000 feet from a producing well, although a partnership may
                drill a new well or re-enter an existing well which is closer
                than 1,000 feet to a plugged and abandoned well.

If the Partnership abandons its interest in a well, then this restriction will
continue for one year following the abandonment.

4.03(d)(2). TRANSFER OF LESS THAN THE MANAGING GENERAL PARTNER'S AND ITS
AFFILIATES' ENTIRE INTEREST. A sale, transfer or a conveyance to the Partnership
of less than all of the ownership of the Managing General Partner or an
Affiliate (excluding

                                       23


another Program in which the interest of the Managing General Partner or its
Affiliates is substantially similar to or less than their interest in the
Partnership) in any Prospect shall not be made unless:

        (i)     the interest retained by the Managing General Partner or the
                Affiliate is a proportionate Working Interest;

        (ii)    the respective obligations of the Managing General Partner or
                its Affiliates and the Partnership are substantially the same
                after the sale of the interest by the Managing General Partner
                or its Affiliates; and

        (iii)   the Managing General Partner's interest in revenues does not
                exceed the amount proportionate to its retained Working
                Interest.

With respect to its retained interest the Managing General Partner shall not
Farmout a Lease for the primary purpose of avoiding payment of its costs
relating to drilling the Lease. This section does not prevent the Managing
General Partner or its Affiliates from subsequently dealing with their retained
interest as they may choose with unaffiliated parties or Affiliated
partnerships.

4.03(d)(3). LIMITATIONS ON SALE OF UNDEVELOPED AND DEVELOPED LEASES TO THE
MANAGING GENERAL PARTNER. Other than another Program managed by the Managing
General Partner and its Affiliates as set forth in Section 4.03(d)(5), the
Managing General Partner and its Affiliates shall not purchase any undeveloped
Leases from the Partnership other than at the higher of Cost or fair market
value. Farmouts to the Managing General Partner and its affiliates may be made
as set forth in Section 4.03(d)(9).

The Managing General Partner and its Affiliates, other than an Affiliated Income
Program, may not purchase any producing natural gas or oil property from the
Partnership unless:

        (i)     the sale is in connection with the liquidation of the
                Partnership; or

        (ii)    the Managing General Partner's well supervision fees under the
                Drilling and Operating Agreement for the well have exceeded the
                net revenues of the well, determined without regard to the
                Managing General Partner's well supervision fees for the well,
                for a period of at least three consecutive months.

In both (i) and (ii), the sale must be at fair market value supported by an
appraisal of an Independent Expert selected by the Managing General Partner.

4.03(d)(4). TRANSACTIONS MUST BE FAIR AND REASONABLE. Neither the Managing
General Partner nor any Affiliate shall sell, transfer, or convey any property
to, or purchase any property from, the Partnership, directly or indirectly,
except under transactions that are fair and reasonable, nor take any action with
respect to the assets or property of the Partnership which does not primarily
benefit the Partnership.

4.03(d)(5). TRANSFER OF LEASES BETWEEN AFFILIATED LIMITED PARTNERSHIPS. The
transfer of an undeveloped Lease from the Partnership to an Affiliated Drilling
Program must be made at fair market value if the undeveloped Lease has been held
for more than two years. Otherwise, if the Managing General Partner deems it to
be in the best interest of the Partnership, the transfer may be made at Cost.

An Affiliated Income Program may purchase a producing natural gas and oil
property from the Partnership at any time at:

        (i)     fair market value as supported by an appraisal from an
                Independent Expert if the property has been held by the
                Partnership for more than six months or significant expenditures
                have been made in connection with the property; or

        (ii)    Cost as adjusted for intervening operations if the Managing
                General Partner deems it to be in the best interest of the
                Partnership.

However, these prohibitions shall not apply to joint ventures or Farmouts among
Affiliated partnerships, provided that:

                                       24


        (i)     the respective obligations and revenue sharing of all parties to
                the transaction are substantially the same; and

        (ii)    the compensation arrangement or any other interest or right of
                either the Managing General Partner or its Affiliates is the
                same in each Affiliated partnership or, if different, the
                aggregate compensation of the Managing General Partner or the
                Affiliate is reduced to reflect the lower compensation
                arrangement.

4.03(d)(6). SALE OF ALL ASSETS. The sale of all or substantially all of the
assets of the Partnership, including without limitation, Leases, wells,
equipment and production therefrom, shall be made only with the consent of
Participants whose Units equal a majority of the total Units.

4.03(d)(7). SERVICES.

4.03(d)(7)(a). COMPETITIVE RATES. The Managing General Partner and any Affiliate
shall not render to the Partnership any oil field, equipage, or other services
nor sell or lease to the Partnership any equipment or related supplies unless
the compensation, price, or rental therefor is competitive with the
compensation, price, or rental of other persons in the area engaged in the
business of rendering comparable services or selling or leasing comparable
equipment and supplies which could reasonably be made available to the
Partnership.

4.03(d)(7)(b). IF NOT DISCLOSED IN THE PRIVATE PLACEMENT MEMORANDUM OR THIS
AGREEMENT THEN SERVICES BY THE MANAGING GENERAL PARTNER MUST BE DESCRIBED IN A
SEPARATE CONTRACT AND CANCELABLE. Any services for which the Managing General
Partner or an Affiliate is to receive compensation other than those described in
this Agreement or the Private Placement Memorandum shall be set forth in a
written contract which precisely describes the services to be rendered and all
compensation to be paid. These contracts shall be cancelable without penalty on
60 days written notice by Participants whose Units equal a majority of the total
Units.

4.03(d)(8). LOANS.

4.03(d)(8)(a). NO LOANS FROM THE PARTNERSHIP. No loans or advances shall be made
by the Partnership to the Managing General Partner or any Affiliate.

4.03(d)(8)(b). LOANS TO THE PARTNERSHIP. Neither the Managing General Partner
nor any Affiliate shall loan money to the Partnership if the interest to be
charged exceeds either:

        (i)     the Managing General Partner's or the Affiliate's interest cost;
                or

        (ii)    that which would be charged to the Partnership, without
                reference to the Managing General Partner's or the Affiliate's
                financial abilities or guarantees, by unrelated lenders, on
                comparable loans for the same purpose.

Neither the Managing General Partner nor any Affiliate shall receive points or
other financing charges or fees, regardless of the amount, although the actual
amount of the charges incurred from third-party lenders may be reimbursed to the
Managing General Partner or the Affiliate.

4.03(d)(9). FARMOUTS. The Managing General Partner shall not enter into a
Farmout to avoid its paying its share of costs related to drilling an
undeveloped Lease. The Partnership may Farmout an undeveloped lease or well
activity to the Managing General Partner, its Affiliates, or unaffiliated
third-parties only if the Managing General Partner, exercising the standard of a
prudent operator, determines that:

        (i)     the Partnership lacks the funds to complete the oil and gas
                operations on the Lease or well and cannot obtain suitable
                financing;

        (ii)    drilling on the Lease or the intended well activity would
                concentrate excessive funds in one location, creating undue
                risks to the Partnership;

                                       25


        (iii)   the Leases or well activity have been downgraded by events
                occurring after assignment to the Partnership so that
                development of the Leases or well activity would not be
                desirable; or

        (iv)    the best interests of the Partnership would be served.

If the Partnership Farmouts a Lease or well activity, the Managing General
Partner must retain on behalf of the Partnership the economic interests and
concessions as a reasonably prudent oil and gas operator would or could retain
under the circumstances prevailing at the time, consistent with industry
practices.

4.03(d)(10). NO COMPENSATING BALANCES. Neither the Managing General Partner nor
any Affiliate shall use the Partnership's funds as compensating balances for its
own benefit.

4.03(d)(11). FUTURE PRODUCTION. Neither the Managing General Partner nor any
Affiliate shall commit the future production of a well developed by the
Partnership exclusively for its own benefit.

4.03(d)(12). MARKETING ARRANGEMENTS. Subject to Section 4.06(c), all benefits
from marketing arrangements or other relationships affecting the property of the
Managing General Partner or its Affiliates and the Partnership shall be fairly
and equitably apportioned according to the respective interests of each in the
property. The Managing General Partner shall treat all wells in a geographic
area equally concerning to whom and at what price the Partnership's natural gas
and oil will be sold and to whom and at what price the natural gas and oil of
other natural gas and oil Programs which the Managing General Partner has
sponsored or will sponsor will be sold. For example, the Managing General
Partner calculates a weighted average selling price for all the natural gas and
oil sold in a geographic area by taking all the money received from the sale of
all the natural gas and oil sold to its customers in the geographic area and
dividing by the volume of all natural gas and oil sold from the wells in that
geographic area. The Managing General Partner, in its sole discretion, shall
determine what constitutes a geographic area.

4.03(d)(13). ADVANCE PAYMENTS. Advance payments by the Partnership to the
Managing General Partner and its Affiliates are prohibited except with respect
to the drilling contracts.

4.03(d)(14). NO REBATES. No rebates or give-ups may be received by the Managing
General Partner or any Affiliate nor may the Managing General Partner or any
Affiliate participate in any reciprocal business arrangements which would
circumvent these guidelines.

4.03(d)(15). PARTICIPATION IN OTHER PARTNERSHIPS. If the Partnership
participates in other partnerships or joint ventures (multi-tier arrangements),
then the terms of any of these arrangements shall not result in the
circumvention of any of the requirements or prohibitions contained in this
Agreement, including the following:

        (i)     there shall be no duplication or increase in Organization and
                Offering Costs, the Managing General Partner's compensation,
                Partnership expenses or other fees and costs;

        (ii)    there shall be no substantive alteration in the fiduciary and
                contractual relationship between the Managing General Partner
                and the Participants; and

        (iii)   there shall be no diminishment in the voting rights of the
                Participants.

4.03(d)(16). ROLL-UP LIMITATIONS.

4.03(d)(16)(a). REQUIREMENT FOR APPRAISAL AND ITS ASSUMPTIONS. In connection
with a proposed Roll-Up, an appraisal of all Partnership assets shall be
obtained from a competent Independent Expert. If the appraisal will be included
in a prospectus used to offer securities of a Roll-Up Entity, then the appraisal
shall be filed with the SEC and the Administrator as an exhibit to the
registration statement for the offering. Thus, an issuer using the appraisal
shall be subject to liability for violation of Section 11 of the Securities Act
of 1933 and comparable provisions under state law for any material
misrepresentations or material omissions in the appraisal.

                                       26


Partnership assets shall be appraised on a consistent basis. The appraisal shall
be based on all relevant information, including current reserve estimates
prepared by an independent petroleum consultant, and shall indicate the value of
the Partnership's assets as of a date immediately before the announcement of the
proposed Roll-Up transaction. The appraisal shall assume an orderly liquidation
of the Partnership's assets over a 12-month period.

The terms of the engagement of the Independent Expert shall clearly state that
the engagement is for the benefit of the Partnership and the Participants. A
summary of the independent appraisal, indicating all material assumptions
underlying the appraisal, shall be included in a report to the Participants in
connection with a proposed Roll-Up.

4.03(d)(16)(b). RIGHTS OF PARTICIPANTS WHO VOTE AGAINST PROPOSAL. In connection
with a proposed Roll-Up, Participants who vote "no" on the proposal shall be
offered the choice of:

        (i)     accepting the securities of the Roll-Up Entity offered in the
                proposed Roll-Up; or

        (ii)    one of the following:

                (a)     remaining as Participants in the Partnership and
                        preserving their Units in the Partnership on the same
                        terms and conditions as existed previously; or

                (b)     receiving cash in an amount equal to the Participants'
                        pro rata share of the appraised value of the net assets
                        of the Partnership based on their respective number of
                        Units.

4.03(d)(16)(c). NO ROLL-UP IF DIMINISHMENT OF VOTING RIGHTS. The Partnership
shall not participate in any proposed Roll-Up which, if approved, would result
in the diminishment of any Participant's voting rights under the Roll-Up
Entity's chartering agreement.

In no event shall the democracy rights of Participants in the Roll-Up Entity be
less than those provided for under Sections 4.03(c)(1) and 4.03(c)(2) of this
Agreement. If the Roll-Up Entity is a corporation, then the democracy rights of
Participants shall correspond to the democracy rights provided for in this
Agreement to the greatest extent possible.

4.03(d)(16)(d). NO ROLL-UP IF ACCUMULATION OF SHARES WOULD BE IMPEDED. The
Partnership shall not participate in any proposed Roll-Up transaction which
includes provisions which would operate to materially impede or frustrate the
accumulation of shares by any purchaser of the securities of the Roll-Up Entity,
except to the minimum extent necessary to preserve the tax status of the Roll-Up
Entity.

The Partnership shall not participate in any proposed Roll-Up transaction which
would limit the ability of a Participant to exercise the voting rights of its
securities of the Roll-Up Entity on the basis of the number of Units held by
that Participant.

4.03(d)(16)(e). NO ROLL-UP IF ACCESS TO RECORDS WOULD BE LIMITED. The
Partnership shall not participate in a Roll-Up in which Participants' rights of
access to the records of the Roll-Up Entity would be less than those provided
for under Sections 4.03(b)(5) and 4.03(b)(6).

4.03(d)(16)(f). COST OF ROLL-UP. The Partnership shall not participate in any
proposed Roll-Up transaction in which any of the costs of the transaction would
be borne by the Partnership if Participants whose Units equal a majority of the
total Units do not vote to approve the proposed Roll-Up.

4.03(d)(16)(g). ROLL-UP APPROVAL. The Partnership shall not participate in a
Roll-Up transaction unless the Roll-Up transaction is approved by Participants
whose Units equal a majority of the total Units.

4.03(d)(17). DISCLOSURE OF BINDING AGREEMENTS. Any agreement or arrangement
which binds the Partnership must be disclosed in the Private Placement
Memorandum.

                                       27


4.04. DESIGNATION, COMPENSATION AND REMOVAL OF MANAGING GENERAL PARTNER AND
REMOVAL OF OPERATOR.

4.04(a). MANAGING GENERAL PARTNER.

4.04(a)(1). TERM OF SERVICE. Atlas shall serve as the Managing General Partner
of the Partnership until either it:

        (i)     is removed pursuant to Section 4.04(a)(3); or

        (ii)    withdraws pursuant to Section 4.04(a)(3)(f).

4.04(a)(2). COMPENSATION OF MANAGING GENERAL PARTNER. In addition to the
compensation set forth in Sections 4.01(a)(4) and 4.02(d)(1), the Managing
General Partner shall receive the compensation set forth in Sections
4.04(a)(2)(b) through 4.04(a)(2)(g).

4.04(a)(2)(a). CHARGES MUST BE NECESSARY AND REASONABLE. Charges by the Managing
General Partner for goods and services must be fully supportable as to:

        (i)     the necessity of the goods and services; and

        (ii)    the reasonableness of the amount charged.

All actual and necessary expenses incurred by the Partnership may be paid out of
the Partnership's subscription proceeds and revenues.

4.04(a)(2)(b). DIRECT COSTS. The Managing General Partner and its Affiliates
shall be reimbursed for all Direct Costs. Direct Costs, however, shall be billed
directly to and paid by the Partnership to the extent practicable.

4.04(a)(2)(c). ADMINISTRATIVE COSTS. The Managing General Partner shall receive
an unaccountable, fixed payment reimbursement for its Administrative Costs of
$75 per well per month. The unaccountable, fixed payment reimbursement of $75
per well per month shall be subject to the following:

        (i)     it shall be proportionately reduced to the extent the
                Partnership acquires less than 100% of the Working Interest in
                the well; and

        (ii)    it shall not be received for plugged or abandoned wells.

4.04(a)(2)(d). GAS GATHERING. The Managing General Partner shall be responsible
for gathering and transporting the natural gas produced by the Partnership to
interstate pipeline systems, local distribution companies and/or end-users in
the area and shall receive a gathering fee at a competitive rate for gathering
and transporting the Partnership's gas. If the Partnership's gas production is
gathered and transported through the gathering system owned by Atlas Pipeline
Partners, then the Managing General Partner shall apply its gathering fee
towards the agreement between Atlas Pipeline Partners and Atlas America, Inc.,
Resource Energy, Inc., and Viking Resources Corporation. If the Partnership's
gas production is gathered and transferred through a gathering system owned by a
third-party, then the Managing General Partner shall pay a portion or all of its
gathering fee to the third-party gathering the natural gas.

4.04(a)(2)(e). DEALER-MANAGER FEE. Subject to Section 3.03(a)(1), the
Dealer-Manager shall receive on each Unit sold:

        (i)     a 3.5% Dealer-Manager fee;

        (ii)    an 8% Sales Commission;

        (iii)   a 1.5% nonaccountable marketing expense fee; and

        (iv)    a .5% nonaccountable due diligence fee.

Finally, as an additional incentive, to the extent permitted by applicable law,
all Selling Agents and the Dealer-Manager that have one or more registered
representatives and/or principals who sell at least six Units each in the
Partnership and/or the other partnership in Atlas America Series 25-2004
Program, shall share in payments from the Managing General Partner in an amount

                                       28


equal to 1% of the Partnership Net Production Revenues in the Partnership and
the other partnership in Atlas America Series 25-2004 Program. A qualifying
broker/dealer's participation in these payments shall be in the ratio which the
total amount of Units sold by all of its registered representatives and/or
principals who sell at least six Units each bears to the total amount of Units
sold by all registered representatives and/or principals who sell at least six
Units each.

4.04(a)(2)(f). DRILLING AND OPERATING AGREEMENT. The Managing General Partner
and its Affiliates shall receive compensation as set forth in the Drilling and
Operating Agreement.

4.04(a)(2)(g). OTHER TRANSACTIONS. The Managing General Partner and its
Affiliates may enter into transactions pursuant to Section 4.03(d)(7) with the
Partnership and shall be entitled to compensation under that section.

4.04(a)(3). REMOVAL OF MANAGING GENERAL PARTNER.

4.04(a)(3)(a). MAJORITY VOTE REQUIRED TO REMOVE THE MANAGING GENERAL PARTNER.
The Managing General Partner may be removed at any time on 60 days' advance
written notice to the outgoing Managing General Partner by the affirmative vote
of Participants whose Units equal a majority of the total Units. If the
Participants vote to remove the Managing General Partner from the Partnership,
then Participants must elect by an affirmative vote of Participants whose Units
equal a majority of the total Units either to:

        (i)     terminate, dissolve, and wind up the Partnership; or

        (ii)    continue as a successor limited partnership under all the terms
                of this Partnership Agreement as provided in Section 7.01(c).

If the Participants elect to continue as a successor limited partnership, then
the Managing General Partner shall not be removed until a substituted Managing
General Partner has been selected by an affirmative vote of Participants whose
Units equal a majority of the total Units and installed as such.

4.04(a)(3)(b). VALUATION OF MANAGING GENERAL PARTNER'S INTEREST IN THE
PARTNERSHIP. If the Managing General Partner is removed, then its interest in
the Partnership shall be determined by appraisal by a qualified Independent
Expert. The Independent Expert shall be selected by mutual agreement between the
removed Managing General Partner and the incoming Managing General Partner. The
appraisal shall take into account an appropriate discount, to reflect the risk
of recovery of natural gas and oil reserves, but not less than that used in the
most recent presentment offer, if any.

The cost of the appraisal shall be borne equally by the removed Managing General
Partner and the Partnership.

4.04(a)(3)(c). INCOMING MANAGING GENERAL PARTNER'S OPTION TO PURCHASE. The
incoming Managing General Partner shall have the option to purchase 20% of the
removed Managing General Partner's interest in the Partnership as Managing
General Partner and not as a Participant for the value determined by the
Independent Expert.

4.04(a)(3)(d). METHOD OF PAYMENT. The method of payment for the removed Managing
General Partner's interest must be fair and protect the solvency and liquidity
of the Partnership. The method of payment shall be as follows:

        (i)     when the termination is voluntary, the method of payment shall
                be a non-interest bearing unsecured promissory note with
                principal payable, if at all, from distributions which the
                Managing General Partner otherwise would have received under the
                Partnership Agreement had the Managing General Partner not been
                terminated; and

        (ii)    when the termination is involuntary, the method of payment shall
                be an interest bearing promissory note coming due in no less
                than five years with equal installments each year. The interest
                rate shall be that charged on comparable loans.

                                       29


4.04(a)(3)(e). TERMINATION OF CONTRACTS. The removed Managing General Partner,
at the time of its removal shall cause, to the extent it is legally possible,
its successor to be transferred or assigned all its rights, obligations and
interests as Managing General Partner of the Partnership in contracts entered
into by it on behalf of the Partnership. In any event, the removed Managing
General Partner shall cause its rights, obligations and interests as Managing
General Partner of the Partnership in any such contract to terminate at the time
of its removal.

Notwithstanding any other provision in this Agreement, the Partnership or the
successor Managing General Partner shall not:

        (i)     be a party to any natural gas supply agreement that the Managing
                General Partner or its Affiliates enters into with a
                third-party;

        (ii)    have any rights pursuant to such natural gas supply agreement;
                or

        (iii)   receive any interest in the Managing General Partner's and its
                Affiliates' pipeline or gathering system or compression
                facilities.

4.04(a)(3)(f). THE MANAGING GENERAL PARTNER'S RIGHT TO VOLUNTARILY WITHDRAW. At
any time beginning 10 years after the Offering Termination Date and the
Partnership's primary drilling activities, the Managing General Partner may
voluntarily withdraw as Managing General Partner on giving 120 days' written
notice of withdrawal to the Participants. If the Managing General Partner
withdraws, then the following conditions shall apply:

        (i)     the Managing General Partner's interest in the Partnership shall
                be determined as described in Section 4.04(a)(3)(b) above with
                respect to removal; and

        (ii)    the interest shall be distributed to the Managing General
                Partner as described in Section 4.04(a)(3)(d)(i) above.

Any successor Managing General Partner shall have the option to purchase 20% of
the withdrawing Managing General Partner's interest in the Partnership at the
value determined as described above with respect to removal.

4.04(a)(3)(g). THE MANAGING GENERAL PARTNER'S RIGHT TO WITHDRAW PROPERTY
INTEREST. The Managing General Partner has the right at any time to withdraw a
property interest held by the Partnership in the form of a Working Interest in
the Partnership Wells equal to or less than its respective interest in the
revenues of the Partnership under the conditions set forth in Section 6.03. If
the Managing General Partner withdraws an interest, then the Managing General
Partner shall:

        (i)     pay the expenses of withdrawing; and

        (ii)    fully indemnify the Partnership against any additional expenses
                which may result from a partial withdrawal of its interests
                including insuring that a greater amount of Direct Costs or
                Administrative Costs is not allocated to the Participants.

4.04(a)(4). REMOVAL OF OPERATOR. The Operator may be removed and a new Operator
may be substituted at any time on 60 days advance written notice to the outgoing
Operator by the Managing General Partner acting on behalf of the Partnership on
the affirmative vote of Participants whose Units equal a majority of the total
Units.

The Operator shall not be removed until a substituted Operator has been selected
by an affirmative vote of Participants whose Units equal a majority of the total
Units and installed as such.

4.05. INDEMNIFICATION AND EXONERATION.

4.05(a)(1). STANDARDS FOR THE MANAGING GENERAL PARTNER NOT INCURRING LIABILITY
TO THE PARTNERSHIP OR PARTICIPANTS. The Managing General Partner, the Operator,
and their Affiliates shall not have any liability whatsoever to the Partnership
or to any Participant for any loss suffered by the Partnership or Participants
which arises out of any action or inaction of the Managing General Partner, the
Operator, or their Affiliates if:

                                       30


        (i)     the Managing General Partner, the Operator, and their Affiliates
                determined in good faith that the course of conduct was in the
                best interest of the Partnership;

        (ii)    the Managing General Partner, the Operator, and their Affiliates
                were acting on behalf of, or performing services for, the
                Partnership; and

        (iii)   the course of conduct did not constitute negligence or
                misconduct of the Managing General Partner, the Operator, or
                their Affiliates.

4.05(a)(2). STANDARDS FOR MANAGING GENERAL PARTNER INDEMNIFICATION. The Managing
General Partner, the Operator, and their Affiliates shall be indemnified by the
Partnership against any losses, judgments, liabilities, expenses, and amounts
paid in settlement of any claims sustained by them in connection with the
Partnership, provided that:

        (i)     the Managing General Partner, the Operator, and their Affiliates
                determined in good faith that the course of conduct which caused
                the loss or liability was in the best interest of the
                Partnership;

        (ii)    the Managing General Partner, the Operator, and their Affiliates
                were acting on behalf of, or performing services for, the
                Partnership; and

        (iii)   the course of conduct was not the result of negligence or
                misconduct of the Managing General Partner, the Operator, or
                their Affiliates.

Provided, however, payments arising from such indemnification or agreement to
hold harmless are recoverable only out of the following:

        (i)     tangible net assets;

        (ii)    revenues from operations; and

        (iii)   any insurance proceeds.

4.05(a)(3). STANDARDS FOR SECURITIES LAW INDEMNIFICATION. Notwithstanding
anything to the contrary contained in the above, the Managing General Partner,
the Operator, and their Affiliates and any person acting as a broker/dealer
shall not be indemnified for any losses, liabilities or expenses arising from or
out of an alleged violation of federal or state securities laws by such party
unless:

        (i)     there has been a successful adjudication on the merits of each
                count involving alleged securities law violations as to the
                particular indemnitee;

        (ii)    the claims have been dismissed with prejudice on the merits by a
                court of competent jurisdiction as to the particular indemnitee;
                or

        (iii)   a court of competent jurisdiction approves a settlement of the
                claims against a particular indemnitee and finds that
                indemnification of the settlement and the related costs should
                be made, and the court considering the request for
                indemnification has been advised of the position of the SEC with
                respect to the issue of indemnification for violation of
                securities laws.

4.05(a)(4). STANDARDS FOR ADVANCEMENT OF FUNDS TO THE MANAGING GENERAL PARTNER
AND INSURANCE. The advancement of Partnership funds to the Managing General
Partner, the Operator, or their Affiliates for legal expenses and other costs
incurred as a result of any legal action for which indemnification is being
sought is permissible only if the Partnership has adequate funds available and
the following conditions are satisfied:

                                       31


        (i)     the legal action relates to acts or omissions with respect to
                the performance of duties or services on behalf of the
                Partnership;

        (ii)    the legal action is initiated by a third-party who is not a
                Participant, or the legal action is initiated by a Participant
                and a court of competent jurisdiction specifically approves the
                advancement; and

        (iii)   the Managing General Partner or its Affiliates undertake to
                repay the advanced funds to the Partnership, together with the
                applicable legal rate of interest thereon, in cases in which
                such party is found not to be entitled to indemnification.

The Partnership shall not bear the cost of that portion of insurance which
insures the Managing General Partner, the Operator, or their Affiliates for any
liability for which they could not be indemnified pursuant to Sections
4.05(a)(1) and 4.05(a)(2).

4.05(b). LIABILITY OF PARTNERS. Under the Delaware Revised Uniform Limited
Partnership Act, the Investor General Partners are liable jointly and severally
for all liabilities and obligations of the Partnership. Notwithstanding the
foregoing, as among themselves, the Investor General Partners agree that each
shall be solely and individually responsible only for his pro rata share of the
liabilities and obligations of the Partnership based on his respective number of
Units.

In addition, the Managing General Partner agrees to use its corporate assets to
indemnify each of the Investor General Partners against all Partnership related
liabilities which exceed the Investor General Partner's interest in the
undistributed net assets of the Partnership and insurance proceeds, if any.
Further, the Managing General Partner agrees to indemnify each Investor General
Partner against any personal liability as a result of the unauthorized acts of
another Investor General Partner.

If the Managing General Partner provides indemnification, then each Investor
General Partner who has been indemnified shall transfer and subrogate his rights
for contribution from or against any other Investor General Partner to the
Managing General Partner.

4.05(c). ORDER OF PAYMENT OF CLAIMS. Claims shall be paid as follows:

        (i)     first, out of any insurance proceeds;

        (ii)    second, out of Partnership assets and revenues; and

        (iii)   last, by the Managing General Partner as provided in Sections
                3.05(b)(2) and (3) and 4.05(b).

No Limited Partner shall be required to reimburse the Managing General Partner,
the Operator, their Affiliates or the Investor General Partners for any
liability in excess of his agreed Capital Contribution, except:

        (i)     for a liability resulting from the Limited Partner's
                unauthorized participation in Partnership management; or

        (ii)    from some other breach by the Limited Partner of this Agreement.

4.05(d). AUTHORIZED TRANSACTIONS ARE NOT DEEMED TO BE A BREACH. No transaction
entered into or action taken by the Partnership, or the Managing General
Partner, the Operator, or their Affiliates, which is authorized by this
Agreement shall be deemed a breach of any obligation owed by the Managing
General Partner, the Operator, or their Affiliates to the Partnership or the
Participants.

4.06. OTHER ACTIVITIES.

4.06(a). THE MANAGING GENERAL PARTNER MAY PURSUE OTHER NATURAL GAS AND OIL
ACTIVITIES FOR ITS OWN ACCOUNT. The Managing General Partner, the Operator, and
their Affiliates are now engaged, and will engage in the future, for their own
account and for the account of others, including other investors, in all aspects
of the natural gas and oil business. This includes

                                       32


without limitation, the evaluation, acquisition, and sale of producing and
nonproducing Leases, and the exploration for and production of natural gas, oil
and other minerals.

The Managing General Partner is required to devote only so much of its time as
is necessary to manage the affairs of the Partnership. Except as expressly
provided to the contrary in this Agreement, and subject to fiduciary duties, the
Managing General Partner, the Operator, and their Affiliates may do the
following:

        (i)     continue their activities, or initiate further such activities,
                individually, jointly with others, or as a part of any other
                limited or general partnership, tax partnership, joint venture,
                or other entity or activity to which they are or may become a
                party, in any locale and in the same fields, areas of operation
                or prospects in which the Partnership may likewise be active;

        (ii)    reserve partial interests in Leases being assigned to the
                Partnership or any other interests not expressly prohibited by
                this Agreement;

        (iii)   deal with the Partnership as independent parties or through any
                other entity in which they may be interested;

        (iv)    conduct business with the Partnership as set forth in this
                Agreement; and

        (v)     participate in such other investor operations, as investors or
                otherwise.

The Managing General Partner and its Affiliates shall not be required to permit
the Partnership or the Participants to participate in any of the operations in
which the Managing General Partner and its Affiliates may be interested or share
in any profits or other benefits from the operations.

4.06(b). MANAGING GENERAL PARTNER MAY MANAGE MULTIPLE PARTNERSHIPS. The Managing
General Partner or its Affiliates may manage multiple Programs simultaneously.

4.06(c). PARTNERSHIP HAS NO INTEREST IN NATURAL GAS CONTRACTS OR PIPELINES AND
GATHERING SYSTEMS. Notwithstanding any other provision in this Agreement, the
Partnership shall not:

        (i)     be a party to any natural gas supply agreement that the Managing
                General Partner, the Operator, or their Affiliates enter into
                with a third-party or have any rights pursuant to such natural
                gas supply agreement; or

        (ii)    receive any interest in the Managing General Partner's, the
                Operator's, and their Affiliates' pipeline or gathering system
                or compression facilities.

                                    ARTICLE V
                      PARTICIPATION IN COSTS AND REVENUES,
                  CAPITAL ACCOUNTS, ELECTIONS AND DISTRIBUTIONS

5.01. PARTICIPATION IN COSTS AND REVENUES. Except as otherwise provided in this
Agreement, costs and revenues shall be charged and credited to the Managing
General Partner and the Participants as set forth in this section and its
subsections.

5.01(a). COSTS. Costs shall be charged as set forth below.

5.01(a)(1). ORGANIZATION AND OFFERING COSTS. Organization and Offering Costs
shall be charged 100% to the Managing General Partner. For purposes of sharing
in revenues under Section 5.01(b)(4), the Managing General Partner shall be
credited with Organization and Offering Costs paid by it and for services
provided by it as Organization Costs up to and including 15% of the
Partnership's subscription proceeds. Any Organization and Offering Costs paid
and/or provided in services by the Managing General Partner in excess of this
amount shall not be credited towards the Managing General Partner's required
Capital Contribution or revenue share set forth in Section 5.01(b)(4). The
Managing General Partner's credit for services provided to the Partnership as
Organization Costs shall be determined based on generally accepted accounting
principles.

5.01(a)(2). INTANGIBLE DRILLING COSTS. Intangible Drilling Costs shall be
charged 100% to the Participants.

                                       33


5.01(a)(3). TANGIBLE COSTS. Tangible Costs shall be charged 66% to the Managing
General Partner and 34% to the Participants. However, if the total Tangible
Costs for all of the Partnership's wells that would be charged to the
Participants exceeds an amount equal to 10% of the Partnership's subscription
proceeds, then the excess shall be charged to the Managing General Partner.

5.01(a)(4). OPERATING COSTS, DIRECT COSTS, ADMINISTRATIVE COSTS AND ALL OTHER
COSTS. Operating Costs, Direct Costs, Administrative Costs, and all other
Partnership costs not specifically allocated shall be charged to the parties in
the same ratio as the related production revenues are being credited.

5.01(a)(5). ALLOCATION OF INTANGIBLE DRILLING COSTS AND TANGIBLE COSTS AT
PARTNERSHIP CLOSINGS. Intangible Drilling Costs and the Participants' share of
Tangible Costs of a well or wells to be drilled and completed with the proceeds
of a Partnership closing shall be charged 100% to the Participants who are
admitted to the Partnership in that closing and shall not be reallocated to take
into account other Partnership closings.

Although the proceeds of each Partnership closing will be used to pay the costs
of drilling different wells, not less than 90% of each Participant's
subscription proceeds shall be applied to Intangible Drilling Costs and not more
than 10% of each Participant's subscription proceeds shall be applied to
Tangible Costs regardless of when he subscribes.

5.01(a)(6). LEASE COSTS. The Leases shall be contributed to the Partnership by
the Managing General Partner as set forth in Section 4.01(a)(4).

5.01(b). REVENUES. Revenues shall be credited as set forth below.

5.01(b)(1). ALLOCATION OF REVENUES ON DISPOSITION OF PROPERTY. If the parties'
Capital Accounts are adjusted to reflect the simulated depletion of a natural
gas or oil property of the Partnership, then the portion of the total amount
realized by the Partnership on the taxable disposition of the property that
represents recovery of its simulated tax basis in the property shall be
allocated to the parties in the same proportion as the aggregate adjusted tax
basis of the property was allocated to the parties or their predecessors in
interest. If the parties' Capital Accounts are adjusted to reflect the actual
depletion of a natural gas or oil property of the Partnership, then the portion
of the total amount realized by the Partnership on the taxable disposition of
the property that equals the parties' aggregate remaining adjusted tax basis in
the property shall be allocated to the parties in proportion to their respective
remaining adjusted tax bases in the property. Thereafter, any excess shall be
allocated to the Managing General Partner in an amount equal to the difference
between the fair market value of the Lease at the time it was contributed to the
Partnership and its simulated or actual adjusted tax basis at that time.
Finally, any excess shall be credited as provided in Section 5.01(b)(4), below.

In the event of a sale of developed natural gas and oil properties with
equipment on the properties, the Managing General Partner may make any
reasonable allocation of proceeds between the equipment and the Leases.

5.01(b)(2). INTEREST. Interest earned on each Participant's subscription
proceeds before the Offering Termination Date under Section 3.05(b)(1) shall be
credited to the accounts of the respective subscribers who paid the subscription
proceeds to the Partnership. The interest shall be paid to the Participant not
later than the Partnership's first cash distribution from operations.

After the Offering Termination Date and until proceeds from the offering are
invested in the Partnership's natural gas and oil operations, any interest
income from temporary investments shall be allocated pro rata to the
Participants providing the subscription proceeds.

All other interest income, including interest earned on the deposit of
production revenues, shall be credited as provided in Section 5.01(b)(4), below.

5.01(b)(3). SALE OR DISPOSITION OF EQUIPMENT. Proceeds from the sale or
disposition of equipment shall be credited to the parties charged with the costs
of the equipment in the ratio in which the costs were charged.

5.01(b)(4). OTHER REVENUES. Subject to Section 5.01(b)(4)(a), the Managing
General Partner and the Participants shall share in all other Partnership
revenues in the same percentage as their respective Capital Contribution bears
to the total Partnership Capital

                                       34


Contributions, except that the Managing General Partner shall receive an
additional 7% of Partnership revenues. However, the Managing General Partner's
total revenue share may not exceed 35% of Partnership revenues. For example, if
the Managing General Partner contributes 25% of the total Partnership Capital
Contributions and the Participants contribute 75% of the total Partnership
Capital Contributions, then the Managing General Partner shall receive 32% of
the Partnership revenues and the Participants shall receive 68% of the
Partnership revenues. On the other hand, if the Managing General Partner
contributes 30% of the total Partnership Capital Contributions and the
Participants contribute 70% of the total Partnership Capital Contributions, then
the Managing General Partner shall receive 35% of the Partnership revenues, not
37%, because its revenue share cannot exceed 35% of Partnership revenues, and
the Participants shall receive 65% of Partnership revenues.

5.01(b)(4)(a). SUBORDINATION. The Managing General Partner shall subordinate up
to 50% of its share of Partnership Net Production Revenues (after deducting the
1% broker/dealer participation) to the receipt by Participants of cash
distributions from the Partnership equal to $2,500 per Unit (which is 10% per
Unit) regardless of their actual subscription price of the Units, in each of the
first five 12-month periods beginning with the Partnership's first cash
distributions from operations. In this regard:

        (i)     the 60-month subordination period shall begin with the first
                cash distribution from operations to the Participants, but no
                subordination distributions to the Participants shall be
                required until the Partnership's first cash distribution to the
                Participants after substantially all Partnership wells have been
                drilled, completed, and placed in production in a sales line;

        (ii)    subsequent subordination distributions, if any, shall be
                determined and made at the time of each subsequent distribution
                of revenues to the Participants; and

        (iii)   the Managing General Partner shall not subordinate more than 50%
                of its share of Partnership Net Production Revenues in any
                subordination period.

The subordination shall be determined by:

        (i)     carrying forward to subsequent 12-month periods the amount, if
                any, by which cumulative cash distributions to Participants,
                including any subordination payments, are less than:

                (a)     $2,500 per Unit (10% per Unit) in the first 12-month
                        period;

                (b)     $5,000 per Unit (20% per Unit) in the second 12-month
                        period;

                (c)     $7,500 per Unit (30% per Unit) in the third 12-month
                        period; or

                (d)     $10,000 per Unit (40% per Unit) in the fourth 12-month
                        period (no carry forward is required if such
                        distributions are less than $12,500 per Unit (50% per
                        Unit) in the fifth 12-month period because the Managing
                        General Partner's subordination obligation terminates on
                        the expiration of the fifth 12-month period); and

        (ii)    reimbursing the Managing General Partner for any previous
                subordination payments to the extent cumulative cash
                distributions to Participants, including any subordination
                payments, would exceed:

                (a)     $2,500 per Unit (10% per Unit) in the first 12-month
                        period;

                (b)     $5,000 per Unit (20% per Unit) in the second 12-month
                        period;

                (c)     $7,500 per Unit (30% per Unit) in the third 12-month
                        period;

                (d)     $10,000 per Unit (40% per Unit) in the fourth 12-month
                        period; or

                (e)     $12,500 per Unit (50% per Unit) in the fifth 12-month
                        period.

                                       35


The Managing General Partner's subordination obligation shall be further subject
to the following conditions:

        (i)     the subordination obligation may be prorated in the Managing
                General Partner's discretion (e.g. in the case of a monthly
                distribution, the Managing General Partner will not have any
                subordination obligation if the distributions to Participants
                equal $208.33 per Unit (8.33% of $2,500 per Unit per year) or
                more assuming there is no subordination owed for any preceding
                period);

        (ii)    the Managing General Partner shall not be required to return
                Partnership distributions previously received by it, even though
                a subordination obligation arises after the distributions;

        (iii)   subject to the foregoing provisions of this section, only
                Partnership revenues in the current distribution period shall be
                debited or credited to the Managing General Partner as may be
                necessary to provide, to the extent possible, subordination
                distributions to the Participants and reimbursements to the
                Managing General Partner;

        (iv)    no subordination payments to the Participants or reimbursements
                to the Managing General Partner shall be made after the
                expiration of the fifth 12-month subordination period; and

        (v)     subordination payments to the Participants shall be subject to
                any lien or priority required by the Managing General Partner's
                lenders pursuant to agreements previously entered into or
                subsequently entered into or renewed by the Managing General
                Partner.

5.01(b)(5). COMMINGLING OF REVENUES FROM ALL PARTNERSHIP WELLS. The revenues
from all Partnership wells will be commingled, so regardless of when a
Participant subscribes he will share in the revenues from all wells on the same
basis as the other Participants.

5.01(c). ALLOCATIONS.

5.01(c)(1). ALLOCATIONS AMONG PARTICIPANTS. Except as provided otherwise in this
Agreement, costs (other than Intangible Drilling Costs and Tangible Costs) and
revenues charged or credited to the Participants as a group, which includes all
revenue credited to the Participants under Section 5.01(b)(4), shall be
allocated among the Participants, including the Managing General Partner to the
extent of any optional subscription under Section 3.03(b)(2), in the ratio of
their respective Units based on $25,000 per Unit regardless of the actual
subscription price for a Participant's Units.

Intangible Drilling Costs and Tangible Costs charged to the Participants as a
group shall be allocated among the Participants, including the Managing General
Partner to the extent of any optional subscription under Section 3.03(b)(2), in
the ratio of the subscription price designated on their respective Subscription
Agreements rather than the number of their respective Units.

5.01(c)(2). COSTS AND REVENUES NOT DIRECTLY ALLOCABLE TO A PARTNERSHIP WELL.
Costs and revenues not directly allocable to a particular Partnership Well or
additional operation shall be allocated among the Partnership Wells or
additional operations in any manner the Managing General Partner in its
reasonable discretion, shall select, and shall then be charged or credited in
the same manner as costs or revenues directly applicable to the Partnership Well
or additional operation are being charged or credited.

5.01(c)(3). MANAGING GENERAL PARTNER'S DISCRETION IN MAKING ALLOCATIONS FOR
FEDERAL INCOME TAX PURPOSES. In determining the proper method of allocating
charges or credits among the parties, or in making any other allocations under
this Agreement, the Managing General Partner may adopt any method of allocation
which it, in its reasonable discretion, selects, if, in its sole discretion
based on advice from its legal counsel or accountants, a revision to the
allocations is required for the allocations to be recognized for federal income
tax purposes either because of the promulgation of Treasury Regulations or other
developments in the tax law. Any new allocation provisions shall be provided by
an amendment to this Agreement and shall be made in a manner that would result
in the most favorable aggregate consequences to the Participants as nearly as
possible consistent with the original allocations described in this Agreement.

                                       36


5.02. CAPITAL ACCOUNTS AND ALLOCATIONS THERETO.

5.02(a). CAPITAL ACCOUNTS FOR EACH PARTY TO THE AGREEMENT. A single, separate
Capital Account shall be established for each party, regardless of the number of
interests owned by the party, the class of the interests and the time or manner
in which the interests were acquired.

5.02(b). CHARGES AND CREDITS.

5.02(b)(1). GENERAL STANDARD. Except as otherwise provided in this Agreement,
the Capital Account of each party shall be determined and maintained in
accordance with Treas. Reg. Section 1.704-l(b)(2)(iv) and shall be increased by:

        (i)     the amount of money contributed by him to the Partnership;

        (ii)    the fair market value of property contributed by him, without
                regard to Section 7701(g) of the Code, to the Partnership, net
                of liabilities secured by the contributed property that the
                Partnership is considered to assume or take subject to under
                Section 752 of the Code; and

        (iii)   allocations to him of Partnership income and gain, or items
                thereof, including income and gain exempt from tax and income
                and gain described in Treas. Reg. Section 1.704-l(b)(2)(iv)(g),
                but excluding income and gain described in Treas. Reg. Section
                1.704-l(b)(4)(i);

and shall be decreased by:

        (iv)    the amount of money distributed to him by the Partnership;

        (v)     the fair market value of property distributed to him, without
                regard to Section 7701(g) of the Code, by the Partnership, net
                of liabilities secured by the distributed property that he is
                considered to assume or take subject to under Section 752 of the
                Code;

        (vi)    allocations to him of Partnership expenditures described in
                Section 705(a)(2)(B) of the Code; and

        (vii)   allocations to him of Partnership loss and deduction, or items
                thereof, including loss and deduction described in Treas. Reg.
                Section 1.704-l(b)(2)(iv)(g), but excluding items described in
                (vi) above, and loss or deduction described in Treas. Reg.
                Section 1.704-l(b)(4)(i) or (iii).

5.02(b)(2). EXCEPTION. If Treas. Reg. Section 1.704-l(b)(2)(iv) fails to provide
guidance, Capital Account adjustments shall be made in a manner that:

        (i)     maintains equality between the aggregate governing Capital
                Accounts of the parties and the amount of Partnership capital
                reflected on the Partnership's balance sheet, as computed for
                book purposes;

        (ii)    is consistent with the underlying economic arrangement of the
                parties; and

        (iii)   is based, wherever practicable, on federal tax accounting
                principles.

5.02(c). PAYMENTS TO THE MANAGING GENERAL PARTNER. The Capital Account of the
Managing General Partner shall be reduced by payments to it pursuant to Section
4.04(a)(2) only to the extent of the Managing General Partner's distributive
share of any Partnership deduction, loss, or other downward Capital Account
adjustment resulting from the payments.

5.02(d). DISCRETION OF MANAGING GENERAL PARTNER IN THE METHOD OF MAINTAINING
CAPITAL ACCOUNTS. Notwithstanding any other provisions of this Agreement, the
method of maintaining Capital Accounts may be changed from time to time, in the
discretion of the Managing General Partner, to take into consideration Section
704 and other provisions of the Code and the related rules, regulations and
interpretations as may exist from time to time.

                                       37


5.02(e). REVALUATIONS OF PROPERTY. In the discretion of the Managing General
Partner the Capital Accounts of the parties may be increased or decreased to
reflect a revaluation of Partnership property, including intangible assets such
as goodwill, on a property-by-property basis except as otherwise permitted under
Section 704(c) of the Code and the regulations thereunder, on the Partnership's
books, in accordance with Treas. Reg. Section 1.704-l(b)(2)(iv)(f).

5.02(f). AMOUNT OF BOOK ITEMS. In cases where Section 704(c) of the Code or
Section 5.02(e) applies, Capital Accounts shall be adjusted in accordance with
Treas. Reg. Section 1.704-l(b)(2)(iv)(g) for allocations of depreciation,
depletion, amortization and gain and loss, as computed for book purposes, with
respect to the property.

5.03. ALLOCATION OF INCOME, DEDUCTIONS AND CREDITS.

5.03(a). IN GENERAL.

5.03(a)(1). DEDUCTIONS ARE ALLOCATED TO PARTY CHARGED WITH EXPENDITURE. To the
extent permitted by law and except as otherwise provided in this Agreement, all
deductions and credits, including, but not limited to, intangible drilling and
development costs and depreciation, shall be allocated to the party who has been
charged with the expenditure giving rise to the deductions and credits; and to
the extent permitted by law, these parties shall be entitled to the deductions
and credits in computing taxable income or tax liabilities to the exclusion of
any other party. Also, any Partnership deductions that would be nonrecourse
deductions if they were not attributable to a loan made or guaranteed by the
Managing General Partner or its Affiliates shall be allocated to the Managing
General Partner to the extent required by law.

5.03(a)(2). INCOME AND GAIN ALLOCATED IN ACCORDANCE WITH REVENUES. Except as
otherwise provided in this Agreement, all items of income and gain, including
gain on disposition of assets, shall be allocated in accordance with the related
revenue allocations set forth in Section 5.01(b) and its subsections.

5.03(b). TAX BASIS OF EACH PROPERTY. Subject to Section 704(c) of the Code, the
tax basis of each oil and gas property for computation of cost depletion and
gain or loss on disposition shall be allocated and reallocated when necessary
based on the capital interest in the Partnership as to the property and the
capital interest in the Partnership for this purpose as to each property shall
be considered to be owned by the parties in the ratio in which the expenditure
giving rise to the tax basis of the property has been charged as of the end of
the year.

5.03(c). GAIN OR LOSS ON OIL AND GAS PROPERTIES. Each party shall separately
compute its gain or loss on the disposition of each natural gas and oil property
in accordance with the provisions of Section 613A(c)(7)D) of the Code, and the
calculation of the gain or loss shall consider the party's adjusted basis in his
property interest computed as provided in Section 5.03(b) and the party's
allocable share of the amount realized from the disposition of the property.

5.03(d). GAIN ON DEPRECIABLE PROPERTY. Gain from each sale or other disposition
of depreciable property shall be allocated to each party whose share of the
proceeds from the sale or other disposition exceeds its contribution to the
adjusted basis of the property in the ratio that the excess bears to the sum of
the excesses of all parties having an excess.

5.03(e). LOSS ON DEPRECIABLE PROPERTY. Loss from each sale, abandonment or other
disposition of depreciable property shall be allocated to each party whose
contribution to the adjusted basis of the property exceeds its share of the
proceeds from the sale, abandonment or other disposition in the proportion that
the excess bears to the sum of the excesses of all parties having an excess.

5.03(f). ALLOCATION IF RECAPTURE TREATED AS ORDINARY INCOME. Any recapture
treated as an increase in ordinary income by reason of Sections 1245, 1250, or
1254 of the Code shall be allocated to the parties in the amounts in which the
recaptured items were previously allocated to them; provided that to the extent
recapture allocated to any party is in excess of the party's gain from the
disposition of the property, the excess shall be allocated to the other parties
but only to the extent of the other parties' gain from the disposition of the
property.

5.03(g). TAX CREDITS. As of the date of the Private Placement Memorandum, tax
credits are not available to the Partnership. If this changes in the future,
however, and if a Partnership expenditure, whether or not deductible, that gives
rise to a tax credit in

                                       38


a Partnership taxable year also gives rise to valid allocations of Partnership
loss or deduction, or other downward Capital Account adjustments, for the year,
then the parties' interests in the Partnership with respect to the credit, or
the cost giving rise thereto, shall be in the same proportion as the parties'
respective distributive shares of the loss or deduction, and adjustments.
Identical principles shall apply in determining the parties' interests in the
Partnership with respect to tax credits that arise from receipts of the
Partnership, whether or not taxable.

5.03(h). DEFICIT CAPITAL ACCOUNTS AND QUALIFIED INCOME OFFSET. Notwithstanding
any provisions of this Agreement to the contrary, an allocation of loss or
deduction which would result in a party having a deficit Capital Account balance
as of the end of the taxable year to which the allocation relates, if charged to
the party, to the extent the Participant is not required to restore the deficit
to the Partnership, taking into account:

        (i)     adjustments that, as of the end of the year, reasonably are
                expected to be made to the party's Capital Account for depletion
                allowances with respect to the Partnership's natural gas and oil
                properties;

        (ii)    allocations of loss and deduction that, as of the end of the
                year, reasonably are expected to be made to the party under
                Sections 704(e)(2) and 706(d) of the Code and Treas. Reg.
                Section 1.751-1(b)(2)(ii); and

        (iii)   distributions that, as of the end of the year, reasonably are
                expected to be made to the party to the extent they exceed
                offsetting increases to the party's Capital Account, assuming
                for this purpose that the fair market value of Partnership
                property equals its adjusted tax basis, that reasonably are
                expected to occur during or prior to the Partnership taxable
                years in which the distributions reasonably are expected to be
                made;

shall be charged to the Managing General Partner. Further, the Managing General
Partner shall be credited with an additional amount of Partnership income or
gain equal to the amount of the loss or deduction as quickly as possible to the
extent such chargeback does not cause or increase deficit balances in the
parties' Capital Accounts which are not required to be restored to the
Partnership.

Notwithstanding any provisions of this Agreement to the contrary, if a party
unexpectedly receives an adjustment, allocation, or distribution described in
(i), (ii), or (iii) above, or any other distribution, which causes or increases
a deficit balance in the party's Capital Account which is not required to be
restored to the Partnership, the party shall be allocated items of income and
gain, consisting of a pro rata portion of each item of Partnership income,
including gross income, and gain for the year, in an amount and manner
sufficient to eliminate the deficit balance as quickly as possible.

5.03(i). MINIMUM GAIN CHARGEBACK. To the extent there is a net decrease during a
Partnership taxable year in the minimum gain attributable to a Partner
nonrecourse debt, then any Partner with a share of the minimum gain attributable
to the debt at the beginning of the year shall be allocated items of Partnership
income and gain in accordance with Treas. Reg. Section 1.704-2(i).

5.03(j). PARTNERS' ALLOCABLE SHARES. Except as otherwise provided in this
Agreement, each party's allocable share of Partnership income, gain, loss,
deductions and credits shall be determined by the use of any method prescribed
or permitted by the Secretary of the Treasury by regulations or other guidelines
and selected by the Managing General Partner which takes into account the
varying interests of the parties in the Partnership during the taxable year. In
the absence of such regulations or guidelines, except as otherwise provided in
this Agreement, the allocable share shall be based on actual income, gain, loss,
deductions and credits economically accrued each day during the taxable year in
proportion to each party's varying interest in the Partnership on each day
during the taxable year.

5.04. ELECTIONS.

5.04(a). ELECTION TO DEDUCT INTANGIBLE COSTS. The Partnership's federal income
tax return shall be made in accordance with an election under the option granted
by the Code to deduct intangible drilling and development costs.

5.04(b). NO ELECTION OUT OF SUBCHAPTER K. No election shall be made by the
Partnership, any Partner, or the Operator for the Partnership to be excluded
from the application of the partnership provisions of Subchapter K of the Code.

                                       39


5.04(c). CONTINGENT INCOME. If it is determined that any taxable income results
to any party by reason of its entitlement to a share of profits or revenues of
the Partnership before the profit or revenue has been realized by the
Partnership, the resulting deduction as well as any resulting gain, shall not
enter into Partnership net income or loss but shall be separately allocated to
the party.

5.04(d). SECTION 754 ELECTION. In the event of the transfer of an interest in
the Partnership, or on the death of an individual party hereto, or in the event
of the distribution of property to any party, the Managing General Partner may
choose for the Partnership to file an election in accordance with the applicable
Treasury Regulations to cause the basis of the Partnership's assets to be
adjusted for federal income tax purposes as provided by Sections 734 and 743 of
the Code.

5.05. DISTRIBUTIONS.

5.05(a). IN GENERAL.

5.05(a)(1). MONTHLY REVIEW OF ACCOUNTS. The Managing General Partner shall
review the accounts of the Partnership at least monthly to determine whether
cash distributions are appropriate and the amount to be distributed, if any.

5.05(a)(2). DISTRIBUTIONS. The Partnership shall distribute funds to the
Managing General Partner and the Participants allocated to their accounts which
the Managing General Partner deems unnecessary to retain by the Partnership.

5.05(a)(3). NO BORROWINGS. In no event, however, shall funds be advanced or
borrowed for distributions if the amount of the distributions would exceed the
Partnership's accrued and received revenues for the previous four quarters, less
paid and accrued Operating Costs with respect to the revenues. The determination
of revenues and costs shall be made in accordance with generally accepted
accounting principles, consistently applied.

5.05(a)(4). DISTRIBUTIONS TO THE MANAGING GENERAL PARTNER. Cash distributions
from the Partnership to the Managing General Partner shall only be made as
follows:

        (a)     in conjunction with distributions to Participants; and

        (b)     out of funds properly allocated to the Managing General
                Partner's account.

5.05(a)(5). RESERVE. At any time after one year from the date each Partnership
Well is placed into production, the Managing General Partner shall have the
right to deduct each month from the Partnership's proceeds of the sale of the
production from the well up to $200 for the purpose of establishing a fund to
cover the estimated costs of plugging and abandoning the well. All of these
funds shall be deposited in a separate interest bearing account for the benefit
of the Partnership, and the total amount so retained and deposited shall not
exceed the Managing General Partner's reasonable estimate of the costs.

5.05(b). DISTRIBUTION OF UNCOMMITTED SUBSCRIPTION PROCEEDS. Any net subscription
proceeds not expended or committed for expenditure, as evidenced by a written
agreement, by the Partnership within 12 months of the Offering Termination Date,
except necessary operating capital, shall be distributed to the Participants in
the ratio that the subscription price designated on each Participant's
Subscription Agreement bears to the total subscription prices designated on all
of the Participants' Subscription Agreements, as a return of capital.

For purposes of this subsection, "committed for expenditure" shall mean
contracted for, actually earmarked for or allocated by the Managing General
Partner to the Partnership's drilling operations, and "necessary operating
capital" shall mean those funds which, in the opinion of the Managing General
Partner, should remain on hand to assure continuing operation of the
Partnership.

5.05(c). DISTRIBUTIONS ON WINDING UP. On the winding up of the Partnership
distributions shall be made as provided in Section 7.02.

5.05(d). INTEREST AND RETURN OF CAPITAL. No party shall under any circumstances
be entitled to any interest on amounts retained by the Partnership. Each
Participant shall look only to his share of distributions, if any, from the
Partnership for a return of his Capital Contribution.

                                       40

profits, losses, income, gain, credits and cash distributions or returns of
capital to which his assignor would otherwise be entitled.

6.01(b). CONVERSION OF INVESTOR GENERAL PARTNER UNITS TO LIMITED PARTNER UNITS.

6.01(b)(1). AUTOMATIC CONVERSION. After all of the Partnership Wells have been
drilled and completed, as determined by the Managing General Partner, the
Managing General Partner shall file an amended certificate of limited
partnership with the Secretary of State of the State of Delaware for the purpose
of converting the Investor General Partner Units to Limited Partner Units.

6.01(b)(2). INVESTOR GENERAL PARTNERS SHALL HAVE CONTINGENT LIABILITY. On
conversion the Investor General Partners shall be Limited Partners entitled to

additional Capital Contribution required for their proportionate share of any
Partnership obligation or liability arising before the conversion of their Units
as provided in Section 3.05(b)(2).

6.01(b)(3). CONVERSION SHALL NOT AFFECT ALLOCATIONS. The conversion shall not
affect the allocation to any Participant of any item of Partnership income,
gain, loss, deduction or credit or other item of special tax significance other
than Partnership liabilities, if any. Further, the conversion shall not affect
any Participant's interest in the Partnership's natural gas and oil properties
and unrealized receivables.

6.01(b)(4). RIGHT TO CONVERT IF REDUCTION OF INSURANCE. Notwithstanding the
foregoing, the Managing General Partner shall notify all Participants at least
30 days before the effective date of any adverse material change in the

pledged, hypothecated, or transferred unless there is either:

        (i)     an effective registration of the Unit under the Securities Act
                of 1933, as amended, and qualification under applicable state
                securities laws; or

        (ii)    an opinion of counsel acceptable to the Managing General Partner
                that the registration and qualification of the Unit is not
                required.

Transfers are also subject to any conditions contained in the Subscription
Agreement and Annex A to the Subscription Agreement.

6.02(a)(3). SUBSTITUTE PARTICIPANT.

6.02(a)(3)(a). PROCEDURE TO BECOME SUBSTITUTE PARTICIPANT. Subject to Sections
6.02(a)(1) and 6.02(a)(2), an assignee of a Participant's Unit shall become a
substituted Participant entitled to all the rights of a Participant if, and only
if:

        (i)     the assignor gives the assignee the right;

        (ii)    the Managing General Partner consents to the substitution, which
                shall be in the Managing General Partner's absolute discretion;

        (iii)   the assignee pays to the Partnership all costs and expenses
                incurred in connection with the substitution; and

        (iv)    the assignee executes and delivers the instruments necessary to
                establish that a legal transfer has taken place and to confirm
                the agreement of the assignee to be bound by all of the terms of
                this Agreement.

6.02(a)(3)(b). RIGHTS OF SUBSTITUTE PARTICIPANT. A substitute Participant is
entitled to all of the rights attributable to full ownership of the assigned
Units including the right to vote.

6.02(b). EFFECT OF TRANSFER.

6.02(b)(1). AMENDMENT OF RECORDS. The Partnership shall amend its records at
least once each calendar quarter to effect the substitution of substituted
Participants.

Any transfer permitted under this Agreement when the assignee does not become a
substituted Participant shall be effective as follows:

        (i)     midnight of the last day of the calendar month in which it is
                made; or

        (ii)    at the Managing General Partner's election, 7:00 A.M. of the
                following day.

6.02(b)(2). TRANSFER DOES NOT RELIEVE TRANSFEROR OF CERTAIN COSTS. No transfer,
including a transfer of less than all of a Participant's Units or the transfer
of Units to more than one party, shall relieve the transferor of its
responsibility for its proportionate part of any expenses, obligations and
liabilities under this Agreement related to the Units so transferred, whether
arising before or after the transfer.

                                       42


6.02(b)(3). TRANSFER DOES NOT REQUIRE AN ACCOUNTING. No transfer of a Unit shall
require an accounting by the Managing General Partner. Also, no transfer shall
grant rights under this Agreement, including the exercise of any elections, as
between the transferring parties and the remaining parties to this Agreement to
more than one party unanimously designated by the transferees and, if he should
have retained an interest under this Agreement, the transferor.

6.02(b)(4). NOTICE. Until the Managing General Partner receives a proper notice
of designation acceptable to it, the Managing General Partner shall continue to
account only to the person to whom it was furnishing notices before the time
pursuant to Section 8.01 and its subsections. This party shall continue to
exercise all rights applicable to the Units previously owned by the transferor.

6.03. RIGHT OF MANAGING GENERAL PARTNER TO HYPOTHECATE AND/OR WITHDRAW ITS
INTERESTS. The Managing General Partner shall have the authority without the
consent of the Participants and without affecting the allocation of costs and
revenues received or incurred under this Agreement, to hypothecate, pledge, or
otherwise encumber, on any terms it chooses for its own general purposes either:

        (i)     its Partnership interest; or

        (ii)    an undivided interest in the assets of the Partnership equal to
                or less than its respective interest in the revenues of the
                Partnership.

All repayments of these borrowings and costs, interest or other charges related
to the borrowings shall be borne and paid separately by the Managing General
Partner. In no event shall the repayments, costs, interest, or other charges
related to the borrowing be charged to the account of the Participants.

In addition, subject to a required participation of not less than 1% of the
Partnership's subscription proceeds, the Managing General Partner may withdraw a
property interest in the form of a Working Interest in the Partnership's wells
equal to or less than its revenue interest without the consent of the
Participants.

6.04. PRESENTMENT.

6.04(a). IN GENERAL. Participants shall have the right to present their Units to
the Managing General Partner for purchase subject to the conditions and
limitations set forth in this section. A Participant, however, is not obligated
to present his Units for purchase. If a Participant elects to present his Units
to the Managing General Partner for purchase, the Managing General Partner is
not required to pay the presentment price in cash. The Managing General Partner,
in its discretion, may offer the Participant other consideration which the
Participant has the option of accepting in exchange for his Units or rejecting
and keeping his Units.

The Managing General Partner shall not be obligated to purchase more than 10% of
the Units in any calendar year and this 10% limit may not be waived. The
Managing General Partner shall not purchase less than one Unit unless the lesser
amount represents the Participant's entire interest in the Partnership, however,
the Managing General Partner may waive this limitation.

A Participant may present his Units in writing to the Managing General Partner
every year beginning in 2009 subject to the following conditions:

        (i)     the presentment must be made within 120 days of the reserve
                report set forth in Section 4.03(b)(3), a summary of which shall
                be provided to a Participant, but only in connection with the
                presentment as set forth in Section 6.04(b);

        (ii)    in accordance with Treas. Reg. Section 1.7704-1(f), the purchase
                may not be made until at least 60 calendar days after the
                Participant notifies the Partnership in writing of the
                Participant's intention to exercise the presentment right; and

        (iii)   the purchase shall not be considered effective until the
                Participant:

                                       43


                (a)     receives the information concerning his interest in the
                        net revenues;

                (b)     agrees to the presentment price; and

                (c)     has been paid in cash or other consideration.

6.04(b). REQUIREMENT FOR INDEPENDENT PETROLEUM CONSULTANT. The amount of the
presentment price attributable to Partnership reserves shall be determined based
on the last reserve report of the Partnership prepared by the Managing General
Partner. Beginning in 2007 and every other year thereafter, the reserve
computations shall be reviewed by an Independent Expert.

However, until the Participant requests the Managing General Partner to purchase
his Units, the Managing General Partner shall not provide a Participant
information concerning the Partnership's Proved Reserves, the present worth of
future net revenues attributable to the Partnership's Proved Reserves, and the
Participant's interest in the present worth of the Partnership's future net
revenues. The calculation of the presentment price shall be as set forth in
Section 6.04(c).

At the time of the presentment, but not before, the Managing General Partner
shall estimate the present worth of future net revenues attributable to the
Partnership's interest in the Proved Reserves. In making this estimate, the
Managing General Partner shall use the following terms:

        (i)     a discount rate equal to 10%;

        (ii)    a constant price for the oil; and

        (iii)   base the price of natural gas on the existing natural gas
                contracts at the time of the purchase.

6.04(c). CALCULATION OF PRESENTMENT PRICE. The presentment price shall be based
on the Participant's share of the net assets and liabilities of the Partnership
and allocated pro rata to each Participant in the ratio that his number of Units
bears to the total number of Units. The presentment price shall include the sum
of the following Partnership items:

        (i)     an amount based on 70% of the present worth of future net
                revenues from the Proved Reserves determined as described in
                Section 6.04(b);

        (ii)    cash on hand;

        (iii)   prepaid expenses and accounts receivable less a reasonable
                amount for doubtful accounts; and

        (iv)    the estimated market value of all assets, not separately
                specified above, determined in accordance with standard industry
                valuation procedures.

There shall be deducted from the foregoing sum the following items:

        (i)     an amount equal to all debts, obligations, and other
                liabilities, including accrued expenses; and

        (ii)    any distributions made to the Participants between the date of
                the request and the actual payment. However, if any cash
                distributed was derived from the sale, after the presentment
                request, of natural gas, oil or other mineral production, or of
                a producing property owned by the Partnership, for purposes of
                determining the reduction of the presentment price, the
                distributions shall be discounted at the same rate used to take
                into account the risk factors employed to determine the present
                worth of the Partnership's Proved Reserves.

6.04(d). FURTHER ADJUSTMENT MAY BE ALLOWED. The presentment price may be further
adjusted by the Managing General Partner for estimated changes therein from the
date of the report to the date of payment of the presentment price to the
Participants because of the following:

                                       44


        (i)     the production or sales of, or additions to, reserves and lease
                and well equipment, sale or abandonment of Leases, and similar
                matters occurring before the request for purchase; and

        (ii)    any of the following occurring before payment of the presentment
                price to the selling Participants:

                (a)     changes in well performance;

                (b)     increases or decreases in the market price of natural
                        gas, oil or other minerals;

                (c)     revision of regulations relating to the importing of
                        hydrocarbons;

                (d)     changes in income, ad valorem, and other tax laws such
                        as material variations in the provisions for depletion;
                        and

                (e)     similar matters.

6.04(e). SELECTION BY LOT. If less than all Units presented at any time are to
be purchased, then the Participants whose Units are to be purchased will be
selected by lot.

The Managing General Partner's obligation to purchase Units presented may be
discharged for its benefit by a third-party or an Affiliate. The Units of the
selling Participant will be transferred to the party who pays for it. A selling
Participant will be required to deliver an executed assignment of his Units,
together with any other documentation as the Managing General Partner may
reasonably request.

6.04(f). NO OBLIGATION OF THE MANAGING GENERAL PARTNER TO ESTABLISH A RESERVE.
The Managing General Partner shall have no obligation to establish any reserve
to satisfy the presentment obligations under this section.

6.04(g). SUSPENSION OF PRESENTMENT FEATURE. The Managing General Partner may
suspend this presentment feature by so notifying Participants at any time if it:

        (i)     does not have sufficient cash flow; or

        (ii)    is unable to arrange financing or other consideration for this
                purpose on terms it deems reasonable.

In addition, the presentment feature may be conditioned, in the Managing General
Partner's sole discretion, on the Managing General Partner's receipt of an
opinion of counsel that the transfers will not cause the Partnership to be
treated as a "publicly traded partnership" under the Code.

The Managing General Partner shall hold the purchased Units for its own account
and not for resale.

                                   ARTICLE VII

        (ii)    any event which under the Delaware Revised Uniform Limited
                Partnership Act causes the dissolution of a limited partnership.

7.01(c). CONTINUANCE OF PARTNERSHIP EXCEPT ON FINAL TERMINATING EVENT. Other
than the occurrence of a Final Terminating Event, the Partnership or any
successor limited partnership shall not be wound up, but shall be continued by
the parties and their respective successors as a successor limited partnership
under all the terms of this Agreement. The successor limited partnership shall
succeed to all of the assets of the Partnership. As used throughout this
Agreement, the term "Partnership" shall include the successor limited
partnerships and the parties to the successor limited partnerships.

7.02. DISSOLUTION AND WINDING UP.

7.02(a). FINAL TERMINATING EVENT. On the occurrence of a Final Terminating Event
the affairs of the Partnership shall be wound up and there shall be distributed

7.02(b). TIME OF LIQUIDATING DISTRIBUTION. To the extent practicable and in
accordance with sound business practices in the judgment of the Managing General
Partner, liquidating distributions shall be made by:

        (i)     the end of the taxable year in which liquidation occurs,
                determined without regard to Section 706(c)(2)(A) of the Code;
                or

        (ii)    if later, within 90 days after the date of the liquidation.

        (ii)    installment obligations owed to the Partnership.

7.02(c). IN-KIND DISTRIBUTIONS. The Managing General Partner shall not be
obligated to offer in-kind property distributions to the Participants, but may
do so, in its discretion. Any in-kind property distributions to the Participants
shall be made to a liquidating trust or similar entity for the benefit of the
Participants, unless at the time of the distribution:

        (i)     the Managing General Partner offers the individual Participants
                the election of receiving in-kind property distributions and the
                Participants accept the offer after being advised of the risks
                associated with direct ownership; or

        (ii)    there are alternative arrangements in place which assure the
                Participants that they will not, at any time, be responsible for
                the operation or disposition of Partnership properties.

If the Managing General Partner has not received a Participant's consent within
30 days after the Managing General Partner mailed the request for consent, then
it shall be presumed that the Participant has refused his consent.

7.02(d). SALE IF NO CONSENT. Any Partnership asset which would otherwise be
distributed in-kind to a Participant, except for the failure or refusal of the
Participant to give his written consent to the distribution, may instead be sold
by the Managing General Partner at the best price reasonably obtainable from an
independent third-party, who is not an Affiliate of the Managing General Partner
or to itself or its Affiliates, including an Affiliated Income Program, at fair
market value as determined by an Independent Expert selected by the Managing
General Partner.

                                  ARTICLE VIII

General Partner, including a notice requiring concurrence or nonconcurrence,
shall be effective, and any failure to respond binding, irrespective of the
following:

        (i)     whether or not the notice is actually received; or

        (ii)    any disability or death on the part of the noticee, even if the
                disability or death is known to the party giving the notice.

concurrence in a proposed action shall be conclusively deemed to have approved
the action. The Managing General Partner shall send the first request and the

                more of the total Units and approved by an affirmative vote of
                Participants whose Units equal a majority of the total Units.

8.05(b). CIRCUMSTANCES UNDER WHICH THE MANAGING GENERAL PARTNER ALONE MAY AMEND.
