             receipt of such production or the proceeds thereof.

       46.   "Prospect" shall mean an area covering lands which are believed by
             the Managing General Partner to contain subsurface structural or
             stratigraphic conditions making it susceptible to the
             accumulations of hydrocarbons in commercially productive
             quantities at one or more Horizons. The area, which may be
             different for different Horizons, shall be designated by the
             Managing General Partner in writing prior to the conduct of
             Partnership operations and shall be enlarged or contracted from
             time to time on the basis of subsequently acquired information to
             define the anticipated limits of the associated hydrocarbon
             reserves and to include all acreage encompassed therein. A
             "Prospect" with respect to a particular Horizon may be limited to
             the minimum area permitted by state law or local practice,
             whichever is applicable, to protect against drainage from adjacent
             wells if the well to be drilled by the Partnership is to a Horizon
             containing Proved Reserves. Subject to the foregoing sentence,
             with respect to the Clinton/Medina geological formation in Ohio
             and Pennsylvania "Prospect" shall be deemed the drilling or
             spacing unit.

       47.   "Proved Developed Oil and Gas Reserves" shall mean reserves that
             can be expected to be recovered through existing wells with
             existing equipment and operating methods. Additional oil and gas
             expected to be obtained through the application of fluid injection
             or other improved recovery techniques for supplementing the
             natural forces and mechanisms of primary recovery should be
             included as "proved developed reserves" only after testing by a
             pilot project or after the operation of an installed program has
             confirmed through production response that increased recovery will
             be achieved.

       48.   "Proved Reserves" shall mean the estimated quantities of crude
             oil, natural gas, and natural gas liquids which geological and
             engineering data demonstrate with reasonable certainty to be
             recoverable in future years from known reservoirs under existing
             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
             arrangements, but not on escalations based upon future conditions.

             (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:

                                       6

<PAGE>

                    (a)    that portion delineated by drilling and defined by
                           gas-oil and/or oil-water contacts, if any; and

                    (b)    the immediately adjoining portions not yet 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.

       49.   "Proved Undeveloped Reserves" shall mean reserves that are
             expected to be recovered from new wells on undrilled acreage, or
             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.

       50.   "Roll-Up" shall mean a transaction involving the acquisition,
             merger, conversion or consolidation, either directly or
             indirectly, of the Partnership and the issuance of securities of a
             Roll-Up Entity. Such term does not include:

             (i)    a transaction involving securities of the Partnership that
                    have been listed for at least twelve months on a national
                    exchange or traded through the National 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: voting
                    rights; the term of existence of the Partnership; the
                    Managing General Partner's compensation; and the
                    Partnership's investment objectives.

       51.   "Roll-Up Entity" shall mean a partnership, trust, corporation or
             other entity that would be created or survive after the successful
             completion of a proposed roll-up transaction.

       52.   "Sales Commissions" shall mean all underwriting and brokerage
             discounts and commissions incurred in the sale of Units in the
             Partnership payable to registered broker-dealers, but excluding

       54.   "Sponsor" shall mean any person directly or indirectly
             instrumental in organizing, wholly or in part, a program or any
             person who will manage or is entitled to manage or participate in
             the management or control of a program. "Sponsor" includes the
             managing and controlling general partner(s) and any other person
             who actually controls or selects the person who controls 25% or
             more of the exploratory, development or producing activities of
             the program, or any segment thereof, even if that person has not
             entered into a contract at the time of formation of the program.
             "Sponsor" does not include wholly independent third parties such
             as attorneys, accountants, and underwriters whose only
             compensation is for professional services rendered in connection
             with the offering of units. Whenever the context so requires, the

<PAGE>

       (i)   its Capital Contribution pursuant to Section 3.03(b); and

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

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 interests pursuant to
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 pursuant to this
section results in his personal liability to the other Investor General
Partners for the amount in default. The remaining Investor General Partners,
pro rata, 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;

                                      12

       (ii)  shall be entitled to receive 100% of the defaulting Investor
             General Partner's cash distributions directly from the Partnership
             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(a). FIDUCIARY DUTY. The Managing General Partner shall have a fiduciary
responsibility for the safekeeping and use of all funds and assets of the
Partnership, whether or not in the Managing 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. Neither this Agreement nor any other agreement between the
Managing General Partner and the Partnership shall contractually limit any
fiduciary duty owed to the Participants by the Managing General Partner under

       (iv)  investments involving less than 5% of the Partnership Subscription
             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, in such instances
             duplicative fees and expenses shall be prohibited.

3.06(c)(2). PERMISSIBLE INVESTMENTS PRIOR TO INVESTMENT IN PARTNERSHIP
ACTIVITIES. After the Offering Termination 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.

assign or cause to have assigned to the Partnership full or partial interests
in Leases, by any method customary in the oil and gas industry, subject to the
terms and conditions set forth below.

The Partnership shall acquire only Leases reasonably expected to meet the
stated purposes of the Partnership. No Leases shall be acquired for the
purpose of a subsequent sale unless the acquisition is made after a well has
been drilled to a depth sufficient to indicate that such an acquisition would
be in the Partnership's best interest.

4.01(a)(2). FEDERAL AND STATE LEASES. The Partnership is authorized to acquire
Leases on federal and state lands.

4.01(a)(3). MANAGING GENERAL PARTNER'S DISCRETION AS TO TERMS AND BURDENS OF

the acquisitions of Leases or other property may be made under any terms and
obligations,

                                      14

<PAGE>

including any limitations as to the Horizons to be assigned to the
Partnership, and subject to any burdens, as the Managing General Partner deems
necessary in its sole discretion.

4.01(a)(4). COST OF LEASES. All Leases shall be acquired from the Managing
General Partner or its Affiliates and shall be credited towards the Managing
General Partner's required Capital Contribution set forth in Section
3.03(b)(1) at the Cost of the Lease, unless the Managing General Partner shall
have cause to believe that Cost is materially more than the fair market value
of the property, in which case the credit for the contribution will be made at
a price not in excess of the fair market value.

A determination of fair market value must be supported by an appraisal from an
Independent Expert. This opinion and any associated supporting information
must be maintained in the Partnership's records for six years.

4.01(a)(5). THE MANAGING GENERAL PARTNER, OPERATOR OR THEIR AFFILIATES' RIGHTS
IN THE REMAINDER INTERESTS. To the extent the Partnership does not acquire a
full interest in a Lease from the Managing General Partner or its Affiliates,

Partner or its Affiliates which may either retain and exploit it for its own
account or sell or otherwise dispose of all or a part of the remaining
interest.

Profits from the exploitation and/or disposition of their retained interests
in the Leases shall be for the benefit of the Managing General Partner or its
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 the Managing General Partner, the Operator or their
Affiliates to the Partnership or the Participants.

4.01(b). NO OVERRIDING ROYALTY INTERESTS. Neither the Managing General
Partner, the Operator nor any Affiliate shall retain any Overriding Royalty
Interest on the Lease interests acquired by the Partnership.

4.01(c). TITLE AND NOMINEE ARRANGEMENTS.

4.01(c)(1). LEGAL TITLE. Legal title to all Leases acquired by the Partnership
shall be held on a permanent basis in the name of the Partnership. However,
Partnership properties may be held temporarily in the name of the Managing
General Partner, the Operator, their Affiliates, or in the name of any nominee
designated by the Managing General Partner to facilitate the acquisition of
the properties.

4.01(c)(2). MANAGING GENERAL PARTNER'S DISCRETION. The Managing General
Partner shall take the steps which are necessary in its best judgment to
render title to the Leases to be acquired by the Partnership acceptable for
the purposes of the Partnership. The Managing General Partner shall be free,
however, to use its own best judgment in waiving title requirements. The
Managing General Partner shall not be liable to the Partnership or to the
other parties for any mistakes of judgment; nor shall the Managing General
Partner be deemed to be making any warranties or representations, express or
implied, as to the validity or merchantability of the title to the Leases
assigned to the Partnership or the extent of the interest covered thereby
except as otherwise provided in the Drilling and Operating Agreement.

4.01(c)(3). COMMENCEMENT OF OPERATIONS. No operation shall be commenced on the
Leases acquired by the Partnership unless the Managing General Partner is
satisfied that necessary title requirements have been satisfied.

4.02. CONDUCT OF OPERATIONS.

4.02(a). IN GENERAL. The Managing General Partner shall establish a program of
operations for the Partnership. Subject to the limitations contained in
Article III of this Agreement concerning the maximum Capital Contribution
which can be required of a Limited Partner, the Managing General Partner, the
Limited Partners, and the Investor General Partners agree to participate in
the program so established by the Managing General Partner.

4.02(b). MANAGEMENT. Subject to any restrictions contained in this Agreement,
the Managing General Partner shall exercise full control over all operations
of the Partnership.

             supplies and material, services, and personnel and the exercise of
             any options, elections, or decisions under any such agreements;

       (iii) the exercise, on behalf of the Partnership or the parties, in such
             manner as the Managing General Partner in its sole judgment deems
             best, of all rights, elections and options granted or imposed by
             any agreement, statute, rule, regulation, or order;

       (iv)  the making of all decisions concerning the desirability of
             payment, and the payment or supervision of the payment, of all

                    property damage in any one accident or occurrence and in
                    the aggregate; and

             (c)    such excess liability insurance as to bodily injury and
                    property damage with combined limits of $50,000,000, during
                    drilling operations and $10,000,000 thereafter, per
                    occurrence or accident and in the aggregate, which includes
                    $250,000 of seepage, pollution and contamination insurance
                    which protects and defends the insured against property
                    damage or bodily injury claims from third parties (other
                    than a co-owner of the Working Interest) alleging seepage,
                    pollution or contamination damage resulting from an
                    accident. The excess liability insurance shall be in place
                    and effective no later than the Initial Closing Date and

             limitation the conduct or financing, in whole or in part, of the
             drilling and other activities of the Partnership or the conduct of
             additional operations, and the repayment of any such borrowings or
             loans used initially to finance such operations or activities;

                                      17

      (viii) the disposition, hypothecation, sale, exchange, release,
             surrender, reassignment or abandonment of any or all assets of the
             Partnership (including, without limitation, the Leases, wells,
             equipment and production therefrom) provided that the sale of all
             or substantially all of the assets of the Partnership shall only
             be made as provided in Section 4.03(d)(6);

        (ix) the formation of any further limited or general partnership, tax
             partnership, joint venture, or other relationship which it deems
             desirable with any parties who it, in its sole and absolute
             discretion, selects, including any of its Affiliates;

         (x) the control of any matters affecting the rights and obligations of
             the Partnership, including the employment of attorneys to advise

4.02(c)(3)(a). IN GENERAL. The Managing General Partner may subcontract and
delegate all or any part of its duties hereunder to any entity chosen by it,

responsibilities hereunder.

4.02(c)(3)(b). DELEGATION TO OPERATOR. The Managing General Partner is
specifically authorized to delegate any or all of its duties to the Operator
by executing the Drilling and Operating Agreement. This delegation shall not
relieve the Managing General Partner of its responsibilities hereunder.

In no event shall any consideration received for operator services be in
excess of the competitive rates or duplicative of any consideration or

Partner may not benefit by interpositioning itself between the Partnership and
the actual provider of operator services.

4.02(c)(4). RELATED PARTY TRANSACTIONS. Subject to the provisions of Section
4.03 and its subsections, any transaction which the Managing General Partner
is authorized to enter into on behalf of the Partnership under the authority

or its Affiliates based on $37.81 per foot or, with respect to a well which
the Partnership elects not to complete, $20.60 per foot.

Partnership Wells in other areas of the United States shall be drilled at
competitive rates and in no event shall the Managing General Partner or its
Affiliates, as drilling contractor, receive a per foot rate which is not
competitive with the rates charged by unaffiliated contractors in the same
geographic region. No turnkey drilling contracts shall be made between the
Managing

                                      18

<PAGE>

General Partner or its Affiliates and the Partnership.

Neither the Managing General Partner nor its Affiliates shall profit by
drilling in contravention of its fiduciary obligations to the Partnership. The

             endorse and record any and all documents, certificates or other
             instruments required or necessary to amend this Agreement as
             authorized under the terms of this Agreement, or to qualify the
             Partnership as a limited partnership or partnership in commendam
             and to conduct business under the laws of any jurisdiction in
             which the Managing General Partner elects to qualify the
             Partnership or conduct business; and

       (ii)  to create, prepare, complete, execute, file, swear to, deliver,
             endorse and record any and all instruments, assignments, security
             agreements, financing statements, certificates and other documents

attorney-in-fact to take any further action which such attorney-in-fact shall
consider necessary or advisable in connection with any of the foregoing. Each
party acknowledges that the power of attorney granted under this section is a
special power of attorney coupled with an interest and is irrevocable and
shall survive the assignment by a party of the whole or a portion of his
interest in the Partnership; except when the assignment is of such party's
entire interest in the Partnership and the purchaser, transferee or assignee
thereof, with the consent of the Managing General Partner, is admitted as a
successor Participant, the power of attorney shall survive the delivery of the
assignment for the sole purpose of enabling such attorney-in-fact to execute,
acknowledge and file any agreement, certificate, instrument or document
necessary to effect the substitution.

             by the Partnership, or indirectly on behalf of the Partnership, to
             the Managing General Partner, the Operator and their Affiliates.
             In addition, Participants shall be provided the percentage that
             the annual unaccountable, fixed fee reimbursement for
             Administrative Costs bears to annual Partnership revenues.

      (iii)  A description of each Prospect in which the Partnership owns an
             interest, including the cost, location, number of acres under
             lease and the Working Interest owned therein by the Partnership,
             except succeeding reports need contain only material changes, if
             any, regarding the Prospects.

       (iv)  A list of the wells drilled or abandoned by the Partnership during
             the period of the report (indicating whether each of the wells has
             or has not been completed), and a statement of the cost of each
             well completed or abandoned. Justification shall be included for
             wells abandoned after production has commenced.

       (v)   A description of all farmins and joint ventures, made during the

             (e)    a reconciliation of the expenses and revenues in accordance
                    with the provisions of Article V.

4.03(b)(2). TAX INFORMATION. The Partnership shall, by March 15 of each year,
prepare, or supervise the preparation of, and transmit to each Participant the
information needed for the Participant to file his federal income tax return,
any required state income tax return, and any other reporting or filing
requirements imposed by any governmental agency or authority.

4.03(b)(3). RESERVE REPORT. Annually, beginning January 1, 2001, a computation
of the total oil and gas Proved Reserves of the Partnership and the present
worth of the reserves determined using a discount rate of 10%, a constant
price for the oil and basing the price of gas upon the existing gas contracts
shall be provided to each Participant along with each Participant's interest
therein. The reserve computations shall be based upon engineering reports
prepared by the Managing General Partner and reviewed by an Independent
Expert. There shall also be included an estimate of the time required for the
extraction of the reserves and a statement that because of the time period
required to extract the reserves the present value of revenues to be obtained
in the future is less than if immediately receivable.

In addition to the foregoing computation and required estimate, as soon as
possible, and in no event more than 90 days after the occurrence of an event
leading to reduction of the reserves of the Partnership of 10% or more,
excluding reduction as a result of normal production, sales of reserves or
product price changes, a computation and estimate shall be sent to each
Participant.

4.03(b)(4). COST OF REPORTS. The cost of all reports described herein shall be
paid by the Partnership as Direct Costs.

4.03(b)(5). PARTICIPANT ACCESS TO RECORDS. The Participants and/or their
representatives shall be permitted access to all records of the Partnership.
The Participant may inspect and copy any of the records after giving adequate
notice at any reasonable time.

Notwithstanding the foregoing, the Managing General Partner may keep logs,
well reports and other drilling and operating data confidential for reasonable
periods of time. The Managing General Partner may release information
concerning the operations

                                      21

<PAGE>

of the Partnership to the sources that are customary in the industry or
required by rule, regulation, or order of any regulatory body.

4.03(b)(6). REQUIRED LENGTH OF TIME TO HOLD RECORDS. The Managing General
Partner shall maintain and preserve during the term of the Partnership and for
six years thereafter all accounts, books and other relevant documents. This
includes a record that a Participant meets the suitability standards
established in connection with an investment in the Partnership and of fair
market value as set forth in Section 4.01(a)(4).

4.03(b)(7). PARTICIPANT LISTS. The following provisions apply regarding access
to the list of Participants:

       (i)   an alphabetical list of the names, addresses and business
             telephone numbers of the Participants along with the number of
             Units held by each of them (the "Participant List") shall be
             maintained as a part of the books and records of the Partnership
             and shall be available for inspection by any Participant or its
             designated agent at the home office of the Partnership upon the
             request of the Participant;

       (ii)  the Participant List shall be updated at least quarterly to
             reflect changes in the information contained therein;

      (iii)  a copy of the Participant List shall be mailed to any Participant
             requesting the Participant List within 10 days of the written
             request. The copy of the Participant List shall be printed in
             alphabetical order, on white paper, and in a readily readable type
             size (in no event smaller than 10-point type). A reasonable charge
             for copy work shall be charged by the Partnership;

      (iv)   the purposes for which a Participant may request a copy of the
             Participant List include, without limitation, matters relating to
             Participant's voting rights under this Agreement and the exercise
             of Participant's rights under the federal proxy laws; and

      (v)    if the Managing General Partner neglects or refuses to exhibit,
             produce, or mail a copy of the Participant List as requested, the
             Managing General Partner shall be liable to any Participant
             requesting the list for the costs, including attorneys fees,
             incurred by that Participant for compelling the production of the
             Participant List, and for actual damages suffered by any
             Participant by reason of such refusal or neglect. It shall be a
             defense that the actual purpose and reason for the requests for
             inspection or for a copy of the Participant List is to secure the
             list of Participants or other information for the purpose of
             selling such list or information or copies thereof, or of using
             the same for a commercial purpose other than in the interest of
             the applicant as a Participant relative to the affairs of the
             Partnership. The Managing General Partner shall require the
             Participant requesting the Participant List to represent in
             writing that the list was not requested for a commercial purpose
             unrelated to the Participant's interest in the Partnership. The
             remedies provided hereunder to Participants requesting copies of
             the Participant List are in addition to, and shall not in any way
             limit, other remedies available to Participants under federal law,
             or the laws of any state.

4.03(b)(8). STATE FILINGS. Concurrently with their transmittal to
Participants, and as required, the Managing General Partner shall file a copy
of each report provided for in this Section 4.03(b) with the California
Commissioner of Corporations and with the securities commissions of other
states which request the report.

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 by the Managing
General Partner.

Also, meetings of the Participants may be called by Participants whose Agreed
Subscriptions equal 10% or more of the Partnership Subscription for any
matters for which Participants may vote. The call for a meeting by
Participants shall be deemed to have been made upon receipt by the Managing
General Partner of a written request from holders of the requisite percentage
of Agreed Subscriptions stating the purpose(s) of the meeting.

                                      22

<PAGE>

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 Securities and Exchange Commission or other
regulatory authorities.

                                      23

<PAGE>

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 Agreed
Subscriptions equal 10% or more of the Partnership Subscription, 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 Agreed Subscriptions equal a majority of the Partnership
Subscription may, without the concurrence of the Managing General Partner or
its Affiliates, vote to:

       (i)    amend this Agreement; provided however, 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 Participant
              or the Managing General Partner without the approval of the
              Participant or the Managing General Partner. Furthermore, any
              amendment may not affect the classification of Partnership income
              and loss for federal income tax purposes without the unanimous
              approval of all Participants;

       (ii)   dissolve the Partnership;

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

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

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

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

       (vii)  cancel any contract for services with the Managing General
              Partner, the Operator, or their Affiliates without penalty upon
              60 days notice.

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 those matters set forth in Section 4.03(c)(2)(iii) and (v) above,
or regarding any transaction between the Partnership and the Managing General
Partner or its Affiliates.

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
Pennsylvania 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 upon the vote of Limited Partners whose
              Agreed Subscriptions equal a majority of the Agreed Subscriptions
              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

                                      24

<PAGE>

participate in the vote if the Investor General Partners represent the
requisite percentage of the Participants 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 oil, gas 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. Notwithstanding, a Prospect shall be deemed to consist of the
drilling or spacing unit on which the well will be drilled by the Partnership:

       (i)    if the geological feature to which the well will be drilled
              contains Proved Reserves; and

       (ii)   the drilling or spacing unit protects against drainage.

With respect to an oil and gas Prospect located in Ohio and Pennsylvania on
which a well will be drilled by the Partnership to test the Clinton/Medina
geologic formation, a Prospect shall be deemed to consist of the drilling and
spacing unit if it meets the test in the preceding sentence. Neither the
Managing General Partner nor its Affiliates may drill any well within 1,650
feet of an existing Partnership Well in the Clinton/Medina formation in
Pennsylvania, or within 1,100 feet of an existing Partnership Well in Ohio,
within five years of the drilling of the Partnership Well. If the Partnership
abandons its interest in a well, then this restriction will continue for one
year following the abandonment.

If the area constituting the Partnership's Prospect is subsequently enlarged
to encompass any area wherein 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) owns a separate property interest and the
activities of the Partnership were material in establishing the existence of
Proved Undeveloped Reserves which are attributable to the separate property
interest, then the separate property interest or a portion thereof shall be
sold, transferred or conveyed to the Partnership as set forth in Sections
4.01(a)(4), 4.03(d)(1) and 4.03(d)(2).

Notwithstanding the foregoing, Prospects in the Clinton/Medina geological
formation shall not be enlarged or contracted if the Prospect was limited to
the drilling or spacing unit because the well was being drilled to Proved
Reserves in the Clinton/Medina geological formation and the drilling or
spacing unit protected against drainage.

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 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.

Neither the Managing General Partner nor any Affiliate shall retain any
Overriding Royalty Interests or other burdens on an interest sold or
transferred by it to the Partnership.

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.

                                      25

<PAGE>

4.03(d)(3). NO SALE OF LEASES TO THE MANAGING GENERAL PARTNER. The Managing
General Partner and its Affiliates shall not purchase any producing or
non-producing oil and gas properties from the Partnership.

4.03(d)(4). LIMITATIONS ON ACTIVITIES OF THE MANAGING GENERAL PARTNER AND ITS
AFFILIATES ON LEASES ACQUIRED BY THE PARTNERSHIP. During a period of five
years from the Offering Termination Date of the Partnership, if the Managing
General Partner or any of its Affiliates (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)
proposes to acquire an interest from an unaffiliated person in a Prospect in
which the Partnership possesses an interest or in a Prospect in which the
Partnership's interest has been terminated without compensation within one
year preceding such proposed acquisition, the following conditions shall apply:

       (i)   if the Managing General Partner or the 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) does not currently own property
             in the Prospect separately from the Partnership, then neither the
             Managing General Partner nor the Affiliate shall be permitted to
             purchase an interest in the Prospect; and

       (ii)  if the Managing General Partner or the 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) currently owns a proportionate
             interest in the Prospect separately from the Partnership, then the
             interest to be acquired shall be divided between the Partnership
             and the Managing General Partner or the Affiliate in the same
             proportion as is the other property in the Prospect. Provided,
             however, if cash or financing is not available to the Partnership
             to enable it to consummate a purchase of the additional interest
             to which it is entitled, then neither the Managing General Partner
             nor the Affiliate shall be permitted to purchase any additional
             interest in the Prospect.

4.03(d)(5). TRANSFER OF LEASES BETWEEN AFFILIATED LIMITED PARTNERSHIPS. The
Partnership shall not purchase properties from or sell properties to any other
Affiliated partnership. This prohibition, however, shall not apply to joint
ventures among Affiliated partnerships, provided that:

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

       (ii)  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 Agreed Subscriptions equal a majority of the Partnership
Subscription.

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:

       (i)   the person is engaged, independently of the Partnership and as an
             ordinary and ongoing business, in the business of rendering the
             services or selling or leasing the equipment and supplies to a
             substantial extent to other persons in the oil and gas industry in
             addition to the partnerships in which the Managing General Partner
             or an Affiliate has an interest; and

       (ii)  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.

                                      26

<PAGE>

If the person is not engaged in such a business, then the compensation, price
or rental shall be the Cost of the services, equipment or supplies to the
person or the competitive rate which could be obtained in the area, whichever
is less.

4.03(d)(7)(b). IF NOT DISCLOSED IN THE PROSPECTUS OR THIS AGREEMENT THEN
SERVICES BY THE MANAGING GENERAL PARTNER MUST BE DESCRIBED IN A SEPARATE
CONTRACT AND CANCELLABLE. Any services for which the Managing General Partner
or an Affiliate is to receive compensation other than those described in this
Agreement or the Prospectus shall be set forth in a written contract which
precisely describes the services to be rendered and all compensation to be
paid. These contracts are cancellable without penalty upon 60 days written
notice by Participants whose Agreed Subscriptions equal a majority of the
Partnership Subscription.

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 the Managing General Partner's or the Affiliate's interest
cost, or if the interest to be charged exceeds 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). NO FARMOUTS. The Partnership shall not Farmout its Leases.

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. 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 gas will be sold and to
whom and at what price the gas of other oil and gas Programs which the
Managing General Partner has sponsored or will sponsor will be sold. The
Managing General Partner calculates a weighted average selling price for all
the gas sold in a geographic area by taking all money received from the sale
of all the gas sold to its customers in a geographic area and dividing by the
volume of all gas sold from the wells in that geographic area.

Notwithstanding, the Managing General Partner and its Affiliates are parties
to, and contract for, the sale of natural gas with industrial end-users and
will continue to enter into such contracts on their own behalf, and the
Partnership will not be a party to such contracts. The Managing General
Partner and its Affiliates also have a substantial interest in pipeline
facilities and compression facilities, which it is anticipated will be used to
transport the Partnership's gas production as well as Affiliated partnership
and third-party gas production, and the Partnership will not receive any
interest in the Managing General Partner's and its Affiliates' pipeline or
gathering system or compression facilities.

4.03(d)(13). ADVANCE PAYMENTS. Advance payments by the Partnership to the
Managing General Partner and its Affiliates are prohibited except when advance
payments are required to secure the tax benefits of prepaid drilling costs and
for a business purpose. These advance payments, if any, shall not include
nonrefundable payments for completion costs before the time a decision is made
that the well or wells warrant a completion attempt.

                                      27

<PAGE>

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 such 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 expenses, 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 Securities and Exchange Commission and
the Administrator as an exhibit to the registration statement for the
offering. Accordingly, 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.

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;

       (ii)   remaining as Participants in the Partnership and preserving their
              interests therein on the same terms and conditions as existed
              previously; or

       (iii)  receiving cash in an amount equal to the Participants' pro rata
              share of the appraised value of the net assets of the
              Partnership.

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

                                      28
<PAGE>

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 will be less than those
provided for under Sections 4.03(b)(5), 4.03(b)(6) and 4.03(b)(7) of this
Agreement.

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 Agreed Subscriptions
equal 75% of the Partnership Subscription 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 Agreed Subscriptions equal 75% of the Partnership Subscription.

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

4.03(d)(18). TRANSACTIONS MUST BE FAIR AND REASONABLE. Neither the Managing
General Partner nor any Affiliate will sell, transfer, or convey any property
to or purchase any property from the Partnership, directly or indirectly,
except pursuant to 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.

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

4.04(a). MANAGING GENERAL PARTNER.

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 thereof; and

       (ii)   the reasonableness of the amount charged.

All actual and necessary expenses incurred by the Partnership may be paid out
of the Partnership Subscription and out of Partnership revenues.

4.04(a)(2)(b). DIRECT COSTS. The Managing General Partner 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, which shall be proportionately reduced to the
extent the Partnership acquires less than 100% of the Working Interest in the
well. The unaccountable, fixed payment reimbursement of $75 per well per month
shall not be increased in amount during the term of the Partnership. Further,
the Managing General Partner shall not be reimbursed for any additional
Partnership Administrative Costs and the unaccountable, fixed payment
reimbursement of $75 per well per month shall be the entire payment to
reimburse the Managing General Partner for the Partnership's Administrative
Costs. Finally, the Managing General Partner shall not receive the
unaccountable, fixed payment reimbursement of $75 per well per month for
plugged or abandoned wells.

                                      29

transporting the Partnership's gas.

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

       (i)    a 2.5% Dealer-Manager fee;

       (ii)   a 7% Sales Commission;

       (iii)  a .5% reimbursement of marketing expenses; and

       (iv)   a .5% reimbursement of the Selling Agent's bona fide accountable
              due diligence expenses.

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

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 upon 60 days advance
written notice to the outgoing Managing General Partner, by the affirmative
vote of Participants whose Agreed Subscriptions equal a majority of the
Partnership Subscription. If Participants vote to remove the Managing General
Partner from the Partnership, then Participants must elect by an affirmative
vote of Participants whose Agreed Subscriptions equal a majority of the
Partnership Subscription either:

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

       (ii)   to 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
Agreed Subscriptions equal a majority of the Partnership Subscription 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 the Managing
General Partner's 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 oil and gas reserves, but not
less than that utilized 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 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 must 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

                                      30
<PAGE>

              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.

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 be a party to any gas purchase
agreement that the Managing General Partner or its Affiliates enters into with
a third party and shall not have any rights pursuant to such gas purchase
agreement. Further, the Partnership or the successor Managing General Partner
shall not 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 of the
Partnership and the Partnership's primary drilling activities, the Managing
General Partner may voluntarily withdraw as Managing General Partner upon
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 pursuant to the conditions set forth in Section
6.03.

The Managing General Partner shall fully indemnify the Partnership against any
additional expenses which may result from a partial withdrawal of its
interests and the withdrawal may not result in a greater amount of Direct
Costs or Administrative Costs being allocated to the Participants. The
expenses of withdrawing shall be borne by the withdrawing Managing General
Partner.

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

The Operator shall not be removed until a substituted Operator has been
selected by an affirmative vote of Participants whose Agreed Subscriptions
equal a majority of the Partnership Subscription 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:

                                      31

<PAGE>

       (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 tangible net assets of the
Partnership, including 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 Securities and Exchange
             Commission, the Massachusetts Securities Division, and the
             position of any state securities regulatory authority in which
             plaintiffs claim they were offered or sold Partnership Units, 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:

       (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

                                      32

<PAGE>

       (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 the Managing General Partner, the Operator, or their
Affiliates could not be indemnified pursuant to Sections 4.05(a)(1) and
4.05(a)(2).

4.05(b). LIABILITY OF PARTNERS. Pursuant to the Pennsylvania 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 hereby agree that each shall be solely and individually responsible
only for his pro rata share of the liabilities and obligations of the
Partnership.

In addition, the Managing General Partner agrees to use its corporate assets
and not the assets of the Partnership 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.

                                      33

<PAGE>

If the Managing General Partner provides indemnification, then each Investor
General Partner who has been indemnified shall and does hereby 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 the assets and revenues of the Partnership; 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, or 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 to be entered into or taken with such party 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 OIL AND GAS 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 oil and gas business. This includes without limitation, the
evaluation, acquisition and sale of producing and nonproducing Leases, and the
exploration for and production of oil, gas, 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)   may continue its 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)  may reserve partial interests in Leases being assigned to the
             Partnership or any other interests not expressly prohibited by
             this Agreement;

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

       (iv)  may conduct business with the Partnership as set forth herein; and

       (v)   may 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 such
operations in which they may be interested or share in any profits or other
benefits therefrom. However, except as otherwise provided herein, the Managing
General Partner and any of its Affiliates may pursue business opportunities
that are consistent with the Partnership's investment objectives for their own
account only after they have determined that such opportunity either cannot be
pursued by the Partnership because of insufficient funds or because it is not
appropriate for the

                                      34

<PAGE>

Partnership under the existing circumstances.

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 GAS CONTRACTS OR PIPELINES AND
GATHERING SYSTEMS. Notwithstanding any other provision in this Agreement, the
Partnership shall not be a party to any gas supply agreement that the Managing
General Partner, the Operator, or their Affiliates enter into with a third
party and shall not have any rights pursuant to such gas supply agreement.
Further, the Partnership shall not 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
5.01 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, pursuant to Section 5.01(b)(4), the Managing General Partner
shall be credited with Organization and Offering Costs up to and including 15%
of the Partnership Subscription which were paid by the Managing General
Partner. Any Organization and Offering Costs in excess of 15% of the
Partnership Subscription shall be charged 100% to the Managing General Partner
without recourse to the Partnership and the Managing General Partner shall not
be credited with these amounts towards its required Capital Contribution.

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

5.01(a)(3). TANGIBLE COSTS. Tangible Costs shall be charged 43.75% to the
Managing General Partner and 56.25% to the Participants.

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, each Participant will pay the same amount
of the costs regardless of when he subscribes.

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

5.01(b). REVENUES. Revenues of the Partnership from all sources and wells
shall be commingled and credited as set forth below.

5.01(b)(1). ALLOCATION OF REVENUES UPON DISPOSITION OF PROPERTY. If the
Partners' Capital Accounts are adjusted to reflect the simulated depletion of
an oil or gas property of the Partnership, then the portion of the total
amount realized by the Partnership upon the taxable disposition of such
property that represents recovery of its simulated tax basis therein shall be
allocated to the Partners in the same proportion as the aggregate adjusted tax
basis of such property was allocated to such Partners (or their predecessors
in interest). If the Partners' Capital Accounts are adjusted to reflect the
actual depletion of an oil or gas property of the Partnership, then the
portion of the total amount realized by the Partnership upon the taxable

                                      35

<PAGE>

disposition of such property that equals the Partners' aggregate remaining
adjusted tax basis therein shall be allocated to the Partners in proportion to
their respective remaining adjusted tax bases in such 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 such time. Finally, any excess shall be credited to the parties in
accordance with the sharing ratios provided in Section 5.01(b)(4), below.

In the event of a sale of developed oil and gas properties with equipment
thereon, 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 Agreed Subscriptions before the
Offering Termination Date pursuant to Section 3.05(b)(1) shall be credited to
the accounts of the respective subscribers who paid the subscriptions to the
Partnership and paid approximately eight weeks after the Offering Termination
Date.

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

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 such equipment in the ratio in which such costs were charged.

5.01(b)(4). OTHER REVENUES. All other revenues of the Partnership shall be
credited 71% to the Participants and 29% to the Managing General Partner
subject to Sections 5.01(b)(4)(a).

5.01(b)(4)(a). SUBORDINATION. The Managing General Partner shall subordinate
up to 40% of its 29% share of Partnership Net Production Revenues (i.e. up to
11.6% of the Partnership Net Production Revenues), to the receipt by
Participants of cash distributions from the Partnership equal to 10% of their
Agreed Subscriptions in each of the first five 12-month periods of Partnership
operations. The subordination shall begin with the first distribution of
revenues to the Participants. The Managing General Partner, however, shall not
subordinate an amount greater than 40% of its 29% share of Partnership Net
Production Revenues (I.E., net of the related costs as provided in Section
5.01(a)(4)) in any such distribution 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)    10% of Participants' Agreed Subscriptions in the first
                     12-month period;

              (b)    20% of Participants' Agreed Subscriptions in the second
                     12-month period;

              (c)    30% of Participants' Agreed Subscriptions in the third
                     12-month period; or

              (d)    40% of Participants' Agreed Subscriptions in the fourth
                     12-month period (no carry forward is required if such
                     distributions are less than 50% of Participants' Agreed
                     Subscriptions in the fifth 12-month period because the
                     Managing General Partner's subordination obligation
                     terminates upon 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)    10% of Participants' Agreed Subscriptions in the first
                     12-month period;

              (b)    20% of Participants' Agreed Subscriptions in the second
                     12-month period;

                                      36

<PAGE>

              (c)    30% of Participants' Agreed Subscriptions in the third
                     12-month period;

              (d)    40% of Participants' Agreed Subscriptions in the fourth
                     12-month period; or

              (e)    50% of Participants' Agreed Subscriptions in the fifth
                     12-month period.

The Managing General Partner's subordination obligation shall be determined
and paid at the time of each Partnership distribution during the subordination
period, and may be prorated in the Managing General Partner's discretion (e.g.
in the case of a quarterly distribution, the Managing General Partner will not
have any subordination obligation if the distributions to Participants equal
2.5% or more of their Agreed Subscriptions assuming there is no subordination
owed for any preceding periods).

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. Also, no subordination payments to
Participants or reimbursements to the Managing General Partner shall be made
after the expiration of the fifth 12-month subordination period.

Subject to the foregoing provisions of this Section 5.01(b)(4)(a), 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, such distributions to the Participants and reimbursements
to 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 and revenues charged or credited to the Participants as
a group shall be allocated among the Participants (including the Managing
General Partner to the extent of any optional subscription pursuant to Section
3.03(b)(2)) in the ratio of their respective Agreed Subscriptions.

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 such 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
hereunder, 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 such
allocations is required for such 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
herein.

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 to this Agreement,
regardless of the number of interests owned by such party, the class of the
interests and the time

                                      37
<PAGE>

or manner in which such 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 Partners 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
             Partners; 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 such 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 such rules, regulations and
interpretations relating thereto as may exist from time to time.

5.02(e). REVALUATIONS OF PROPERTY. In the discretion of the Managing General
Partner the Capital Accounts of the Partners 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).

                                      38
<PAGE>

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 such 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 upon 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 hereto 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 oil and gas 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. If a Partnership expenditure (whether or not deductible)
that gives rise to a tax credit in 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 Partners' interests in the
Partnership with respect to the credit (or the cost giving rise thereto) shall
be in the same proportion as the Partners' respective distributive shares of
the loss or deduction (and adjustments). Identical principles shall apply in
determining the Partners' interests in the Partnership with respect to tax
credits that arise from receipts of the Partnership (whether or not taxable).

                                      39

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 Participant having a deficit Capital Account
balance as of the end of the taxable year to which the allocation relates, if
charged to the Participant, (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 Participant's Capital Account for
              depletion allowances with respect to the Partnership's oil and
              gas properties;

       (ii)   allocations of loss and deduction that, as of the end of such
              year, reasonably are expected to be made to the Participant
              pursuant to 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 such year, reasonably are
              expected to be made to the Participant to the extent they exceed
              offsetting increases to the Participant'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 such loss or deduction as quickly as
possible (to the extent such chargeback does not cause or increase deficit
balances in the Participants' Capital Accounts which are not required to be
restored to the Partnership).

Notwithstanding any provisions of this Agreement to the contrary, if a
Participant 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 Participant's Capital Account
which is not required to be restored to the Partnership, the Participant 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 such
year) in an amount and manner sufficient to eliminate such 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 such debt at the beginning of such 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 Partner'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 Partners in the Partnership during the
taxable year. In the absence of such regulations or guidelines, except as
otherwise provided in this Agreement, such 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 Partner'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 provisions of Subchapter K of the Code.

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 such 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 such party.

5.04(d). SECTION 754 ELECTION. In the event of the transfer of an interest in
the Partnership, or upon the death of an individual party hereto, or in the

<PAGE>

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). QUARTERLY REVIEW OF ACCOUNTS. The Managing General Partner shall
review the accounts of the Partnership at least quarterly 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.

                                      41

<PAGE>

5.05(a)(3). NO BORROWINGS. In no event, however, shall funds be advanced or
borrowed for purposes of distributions, if the amount of such distributions
would exceed the Partnership's accrued and received revenues for the previous
four quarters, less paid and accrued Operating Costs with respect to such
revenues. The 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 in
conjunction with distributions to Participants and only out of funds properly
allocated to the Managing General Partner's account.

5.05(a)(5). RESERVE. At any time after three years 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 such 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 such 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 of the Partnership, except necessary operating capital, shall
be distributed pro rata to the Participants in the ratio of their Agreed
Subscriptions to the Partnership, as a return of capital. The Managing General
Partner shall reimburse the Participants for the selling or other offering
expenses allocable to the 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. Upon the winding up of the Partnership
distributions shall be made as provided in Section 7.02.

5.05(d). INTEREST AND RETURN OF CAPITAL. It is agreed among the parties hereto
that 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.

                                   ARTICLE VI
                              TRANSFER OF INTERESTS

6.01. TRANSFERABILITY.

6.01(a). IN GENERAL.

6.01(a)(1). CONSENT REQUIRED. In addition to other restrictions on
transferability provided in this Agreement, Units in the Partnership (and any
rights to income or other attributes of Units in the Partnership) shall be
nontransferable except transfers to or with the written consent of the
Managing General Partner.

6.01(a)(2). RIGHTS OF ASSIGNEE. Unless an assignee becomes a substituted
Participant in accordance with the provisions set forth below, he shall not be
entitled to any of the rights granted to a Participant hereunder, other than
the right to receive all or part of the share of the 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
INTERESTS.

6.01(b)(1). AUTOMATIC CONVERSION. After substantially all of the Partnership
Wells have been drilled and completed the

                                      42

<PAGE>

Managing General Partner shall file an amended certificate of limited
partnership with the Secretary of State of the Commonwealth of Pennsylvania
for the purpose of converting the Investor General Partner Units to Limited
Partner interests.

6.01(b)(2). INVESTOR GENERAL PARTNERS SHALL HAVE CONTINGENT LIABILITY. Upon
conversion the Investor General Partners shall be Limited Partners entitled to
limited liability; however, they shall remain liable to the Partnership for
any 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 oil and gas
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
Partnership's insurance coverage. If the insurance coverage is to be
materially reduced, then the Investor General Partners shall have the right to
convert their Units into Limited Partner interests before the reduction by
giving written notice to the Managing General Partner.

6.02. SPECIAL RESTRICTIONS ON TRANSFERS.

6.02(a). IN GENERAL. Only whole Units may be assigned unless the Participant
owns less than a whole Unit, in which case his entire fractional interest must
be assigned. The costs and expenses associated with the assignment must be
paid by the assignor Participant and the assignment must be in a form
satisfactory to the Managing General Partner. The terms of the assignment must
not contravene those of this Agreement. Transfers of interest in the
Partnership are subject to the following additional restrictions set forth in
Sections 6.02(a)(1) and 6.02(a)(2).

6.02(a)(1). SECURITIES LAWS RESTRICTION. Subject to transfers permitted by
Section 6.04 and transfers by operation of law, no interest in the Partnership
shall be sold, assigned, pledged, hypothecated or transferred in the absence
of an effective registration of the Units under the Securities Act of 1933, as
amended and qualification under applicable state securities laws or an opinion
of counsel acceptable to the Managing General Partner that such registration
and qualification are not required. Transfers are also subject to any
conditions contained in the Subscription Agreement and Exhibit (B) to the
Prospectus.

6.02(a)(2). TAX LAW RESTRICTIONS. Subject to transfers permitted by Section
6.04 and transfers by operation of law, no sale, exchange, transfer or
assignment shall be made which, in the opinion of counsel to the Partnership,
would result in:

       (i)    the Partnership being considered to have been terminated for
              purposes of Section 708 of the Code; or

       (ii)   the Partnership being treated as a "publicly-traded" partnership
              for purposes of Section 469(k) of the Code.

6.02(a)(3). SUBSTITUTE PARTICIPANT.

6.02(a)(3)(a). PROCEDURE TO BECOME SUBSTITUTE PARTICIPANT. An assignee of a
Participant's interest in the Partnership shall become a substituted
Participant entitled to all the rights of a Participant if, and only if:

       (i)    the assignor of the Unit gives the assignee the right;

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

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

                                      43

<PAGE>

      (iv)   the assignee of the Unit executes and delivers the instruments (in
             form and substance satisfactory to the Managing General Partner)
             necessary or desirable to effect the substitution and to confirm
             the agreement of the assignee to be bound by all of the terms and
             provisions of this Agreement.

                                      44
<PAGE>

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 hereunder when the assignee does not become a
substituted Participant shall be effective as of midnight of the last day of
the calendar month in which it is made, or, 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 party's rights hereunder or the
transfer of rights hereunder to more than one party) shall relieve the
transferor of its responsibility for its proportionate part of any expenses,
obligations and liabilities hereunder related to the interest so transferred,
whether arising before or after the transfer.

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 hereunder (including the exercise of any elections) as
between the transferring parties and the remaining parties hereto to more than
one party unanimously designated by the transferees and, if he should have
retained an interest hereunder, the transferor.

6.02(b)(4). NOTICE. Until the Managing General Partner receives a proper
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. That party shall continue to
exercise all rights applicable to the entire interest 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 hereunder), to hypothecate, pledge, or otherwise
encumber, on any terms it sees fit, its Partnership interest (or an undivided
interest in the assets of the Partnership equal to or less than its respective
interest in the revenues of the Partnership) to obtain funds for use by it for
its own general purposes.

All repayments of such borrowings and costs and interest or other charges
related thereto 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 Subscription, the Managing General Partner may 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 if:

       (i)    the withdrawal is necessary to satisfy the bona fide request of
              its creditors; or

       (ii)   the withdrawal is approved by Participants whose Agreed
              Subscriptions equal a majority of the Partnership Subscription.

6.04. PRESENTMENT.

6.04(a). IN GENERAL. Participants shall have the right to present their
interests to the Managing General Partner subject to the conditions and
limitations set forth in this section. A Participant, however, is not
obligated to present his Units for repurchase.

The Managing General Partner shall not be obligated to purchase more than 5%
of the Units in any calendar year and shall not purchase less than one Unit of
a Participant's interests in the Partnership unless such lesser amount
represents the entire amount of the Participant's interest. The Managing
General Partner may waive these limitations in its sole discretion other than
the limitation that it shall not purchase more than 5% of the Units in any
calendar year.

                                      45

<PAGE>

A Participant may present his Units in writing to the Managing General Partner
every year beginning in 2004. The presentment must be made within 120 days of
the reserve report set forth in Section 4.03(b)(3). No repurchase shall be
considered effective until the payment has been made to the Participant in
cash.

In addition, in accordance with Treas. Reg. Section 1.7704-1(f), no repurchase
shall occur until at least 60 calendar days after the Participant notifies the
Partnership in writing of the Participant's intention to exercise the
repurchase right.

6.04(b). REQUIREMENT FOR INDEPENDENT PETROLEUM CONSULTANT EVERY OTHER YEAR.
The amount attributable to Partnership reserves shall be determined based upon
the last reserve report of the Partnership prepared by the Managing General
Partner and reviewed by an Independent Expert. 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 a discount rate equal to 10% and a constant
price for the oil; and base the price of gas upon the existing gas contracts
at the time of the repurchase.

The calculation of the repurchase price shall be as set forth in Section
6.04(c).

6.04(c). CALCULATION OF PRESENTMENT PRICE. The presentment price shall be
based upon the Participant's share of the net assets and liabilities of the
Partnership and allocated pro rata to each Participant based upon his Agreed
Subscription. The presentment price shall include the sum of the following
items:

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

       (ii)  Partnership cash on hand;

       (iii) prepaid expenses and accounts receivable of the Partnership, less
             a reasonable amount for doubtful accounts; and

       (iv)  the estimated market value of all assets of the Partnership, 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 Partnership 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, subsequent to the request, of oil, gas
             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 such report to the date of payment of the presentment price
to the Participants:

       (i)   by reason of 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 repurchase; and

       (ii)  by reason of any of the following occurring before payment of the
             presentment price to the selling Participants: changes in well
             performance, increases or decreases in the market price of oil,
             gas, or other minerals, revision of regulations relating to the
             importing of hydrocarbons, changes in income, ad valorem, and
             other tax laws (e.g. material variations in the provisions for
             depletion) and similar matters.

                                      46

<PAGE>

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

The Managing General Partner's obligation to purchase interests presented may
be discharged for its benefit by a third party or an Affiliate. The interests
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
interest, together with such 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:

       (i)    it does not have sufficient cash flow; or

       (ii)   it is unable to borrow funds for such 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 such transfers will not cause the Partnership to
be treated as a "publicly traded partnership" under the Code.

The Managing General Partner shall hold such repurchased Units for its own
account and not for resale.

                                   ARTICLE VII

              a limited partnership.

7.01(c). CONTINUANCE OF PARTNERSHIP EXCEPT UPON FINAL TERMINATING EVENT.
Except upon 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. Such successor
limited partnership shall succeed to all of the assets of the Partnership. As
used throughout this Agreement, the term "Partnership" shall include such
successor limited partnerships and the parties thereto.

7.02. DISSOLUTION AND WINDING UP.

7.02(a). FINAL TERMINATING EVENT. Upon the occurrence of a Final Terminating
Event, the affairs of the Partnership shall be wound up and there shall be
distributed to each of the parties its Distribution Interest in the remaining
assets of the Partnership.

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 the end of the
taxable year in which liquidation occurs (determined without regard to Section
706(c)(2)(A) of the Code) or, if later, within 90 days after the date of such

                                      47

<PAGE>

liquidation.

Notwithstanding, the following amounts need not be distributed within the
foregoing time periods so long as such withheld amounts are distributed as
soon as practical:

       (i)    amounts withheld for reserves reasonably required for liabilities
              of the Partnership; and

       (ii)   installment obligations owed to the Partnership.

7.02(c). IN-KIND DISTRIBUTIONS. 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 shall offer 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 such 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.

It shall be presumed that a Participant has refused his consent if the
Managing General Partner has not received the consent within 30 days after the
Managing General Partner mailed the request for 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.

                                  ARTICLE VIII
                            MISCELLANEOUS PROVISIONS

8.01(a). METHOD. Any notice required hereunder shall be in writing, and given
by mail or wire addressed to the party to receive the notice at the address

notice to any such transferee shall be required, nor shall such transferee
have any rights hereunder, until notice thereof shall have been given to the
Managing General Partner.

Any transfer of rights hereunder shall not increase the duty to give notice.
If there is a transfer of rights hereunder to more than one party, then notice
to any owner of any interest in such rights shall be notice to all owners
thereof.

8.01(b). CHANGE IN ADDRESS. The address of any party hereto may be changed by:

              address by the Managing General Partner; or

given and any applicable time shall run from the date the notice is received.

8.01(d). EFFECTIVENESS OF NOTICE. Any notice to a party other than the
Managing General Partner, including a notice requiring concurrence or
nonconcurrence, shall be effective, and any failure to respond binding,

venue or mandatory arbitration of any or all claims by Participants against
the Sponsor.

8.04. AGREEMENT IN COUNTERPARTS. This Agreement may be executed in counterpart
and shall be binding upon all parties executing this or similar agreements
from and after the date of execution by each party.

for Atlas-Energy for the Nineties-Public #8 Ltd. (as supplemented or amended

In order to induce the Managing General Partner to accept this subscription,

INVESTOR'S INITIALS

_____       The undersigned has received the Prospectus.

_____       The undersigned (other than Minnesota residents) recognizes that
            before this offering there has been no public market for the Units
            and it is unlikely that after the offering there will be any such
            market. In addition, the undersigned understands that the
            transferability of the Units is restricted and that he cannot
            expect to be able to readily liquidate his investment in the Units
            in case of emergency or other change in circumstances.

_____       The undersigned is purchasing the Units for his own account, for
            investment purposes and not for the account of others and he is not
            purchasing the Units with the present intention of reselling them.

_____       The undersigned, if he is an individual, is a citizen of the United
            States of America and is at least twenty-one years of age, or, if a
            partnership, corporation or trust, the members, stockholders or
            beneficiaries thereof are citizens of the United States and each is
            at least twenty-one years of age.

_____       The undersigned, if he is not an individual, is empowered and duly
            authorized under a governing document, trust instrument, pension
            plan, charter, certificate of incorporation, by-law provision or
            the like to enter into this Subscription Agreement and to perform
            the transactions contemplated by the Prospectus, including the
            exhibits thereto.

_____       (a)    The undersigned has:

                   -    a net worth of at least $225,000 (exclusive of home,
                        furnishings and automobiles); or

                   -    a net worth (exclusive of home, furnishings and
                        automobiles) of at least $60,000 and had during the
                        last tax year, or estimates that he will have during
                        the current tax year, "taxable income" as defined in
                        Section 63 of the Code of at least $60,000, without
                        regard to an investment in the Partnership.

            (b)    IN ADDITION, IF A RESIDENT OF ALABAMA, ARIZONA, CALIFORNIA,
                   INDIANA, IOWA, KANSAS, KENTUCKY, MAINE, MASSACHUSETTS,
                   MICHIGAN, MINNESOTA, MISSISSIPPI, MISSOURI, NEW HAMPSHIRE,
                   NEW MEXICO, NORTH CAROLINA, OHIO, OKLAHOMA, OREGON,
                   PENNSYLVANIA, SOUTH DAKOTA, TENNESSEE, TEXAS, VERMONT OR
                   WASHINGTON, THEN THE UNDERSIGNED REPRESENTS THAT HE IS AWARE
                   OF AND MEETS THAT STATE'S QUALIFICATIONS AND SUITABILITY
                   STANDARDS SET FORTH IN EXHIBIT (B) TO THE PROSPECTUS.

            (c)    If the undersigned is a fiduciary, then he is purchasing for
                   a person or entity having the appropriate income and/or net
                   worth specified in (a) or (b) above.

INVESTOR'S INITIALS

_____        An Investor General Partner will have unlimited joint and several
             liability for Partnership obligations and liabilities including
             amounts in excess of his Agreed Subscription to the extent the
             obligations and liabilities exceed the Partnership's insurance
             proceeds, the Partnership's assets and indemnification by the
             Managing General Partner. Insurance may be inadequate to cover
             these liabilities and there is no insurance coverage for certain
             claims.

_____        Partnership losses allocable to a Limited Partner generally may be
             used only to the extent of his net passive income from passive
             activities in such year, with any excess losses being deferred.

THE ABOVE REPRESENTATIONS DO NOT CONSTITUTE A WAIVER OF ANY RIGHTS THAT THE
UNDERSIGNED MAY HAVE UNDER THE ACTS ADMINISTERED BY THE SECURITIES AND
EXCHANGE COMMISSION OR BY ANY STATE REGULATORY AGENCY ADMINISTERING STATUTES
BEARING ON THE SALE OF SECURITIES.

No state or federal governmental authority has made any finding or
determination relating to the fairness for public investment of the Units and
no state or federal governmental authority has recommended or endorsed or will
recommend or endorse the Units.

The Selling Agent or registered representative is required to inform potential
investors of all pertinent facts relating to the Units, including the
following:

          -   the risks involved in the offering, including the speculative
              nature of the investment and the speculative nature of drilling
              for oil and gas;
          -   the financial hazards involved in the offering, including the
              risk of losing the entire investment;
          -   the lack of liquidity of this investment;
          -   the restrictions on transferability of the Units;
          -   the background of the Managing General Partner and the Operator;
          -   the tax consequences of the investment; and
          -   the unlimited joint and several liability of the Investor General
              Partners.

You are required to execute your own Subscription Agreement. The Managing
General Partner will not accept any Subscription Agreement that has been
executed by someone other than you unless the person has been given the legal
power of attorney to sign on your behalf and you meet all of the conditions
herein. In the case of sales to fiduciary accounts, the minimum standards set
forth herein must be met by the beneficiary, the fiduciary account, or by the
donor or grantor who directly or indirectly supplies the funds to purchase the
Partnership interests if the donor or grantor is the fiduciary.

Your execution of the Subscription Agreement constitutes your binding offer to
buy Units in the Partnership. Once you subscribe you may withdraw your
subscription only by providing the Managing General Partner with written
notice of your withdrawal before your subscription is accepted by the Managing
General Partner. The Managing General Partner has the discretion to refuse to
accept your Agreed Subscription without liability to you. Agreed Subscriptions
will be accepted or rejected by the Partnership within 30 days of their
receipt. If your Agreed Subscription is rejected, then all of your funds will
be returned to you immediately.

If your Agreed Subscription is accepted before the first closing, then you
will be admitted as a Participant not later than 15 days after the release
from escrow of the investors' funds to the Partnership. If your Agreed
Subscription is accepted after the first closing, then you will be admitted
into the Partnership not later than the last day of the calendar month in
which your Agreed Subscription was accepted by the Partnership.

The Managing General Partner may not complete a sale of Units to you until at
least five business days after the date you receive a final Prospectus. In
addition, the Managing General Partner will send you a confirmation of
purchase.

NOTICE TO CALIFORNIA RESIDENTS: This offering deviates in certain respects
from various requirements of Title 10 of the California Administrative Code.
These deviations include, but are not limited to the following: the definition
of Prospect in the Prospectus, unlike Rule 260.140.127.2(b) and Rule
260.140.121(1) does not require enlarging or contracting of the size of the
area on the basis of geological data in all cases.

If a resident of California the undersigned acknowledges the receipt of
California Rule 260.141.11 set forth in Exhibit (B) to the Prospectus.
