the shareholders of Borrower which shall be held in escrow by the Lender

     "Collateral Coverage Ratio" shall equal (at any particular time of
determination) the ratio of (a) the Collateral Value to (b) the outstanding
principal and accrued and unpaid interest on the Term Loan(s)(s).

     "Collateral Value" shall mean, when calculated for the Properties, the sum
of (a) + (b) + (c); where:

(a) the present value (calculated using the "discount rate" of 10% per annum)
of the future net operating cash flow from proved developed producing reserves
with the annual quantity of those reserves risked (reduced) by a percentage set
forth in the Schedule, provided however, those proved developed producing
reserves that have been producing for less than six months shall be risked
(reduced) by a different percentage as set forth in the Schedule;

(b) the present value (calculated using the "discount rate" of 10% per annum)
of the future net operating cash flow from proved developed non-producing
reserves with the annual quantity of those reserves risked (reduced) by a
percentage set forth in the Schedule; and

(c) the present value (calculated using the "discount rate" of 10% per annum)
of the future net operating cash flow from proved undeveloped reserves with the
annual quantity of those reserves risked (reduced) by a percentage set forth in
the Schedule.  Proved developed non-producing and proved undeveloped reserves
shall contribute no more to the Collateral Value than the percentage specified
in the Schedule.

     The above calculation shall be based on the following assumptions:

          (i) Reserves shall be adjusted for cumulative production since the
effective date of the most recent Reserve Report or the most recent
determination of the Collateral Value, whichever is applicable.





                                    Page 3

          (ii) (A) For all Crude Oil and Natural Gas to be sold by Borrower on
a fixed price basis pursuant to any bona fide contract or with respect to which
the price has been hedged pursuant to any New York Mercantile Exchange contract
or bona fide price swap agreement or arrangement, including any Price
Protection Agreement (such contract, agreement or hedging arrangement
acceptable to Lender), the price applied to such reserves shall be such fixed
price (as adjusted for appropriate quality, transportation and location
differentials) for such volumes as indicated in such contract, agreement or
arrangement.

               (B) The price applied to all Crude Oil and Natural Gas which is
not subject to any hedging agreement shall be the Market Price (as defined 
below) less the Basis Differential. Market Price for each year in which NYMEX
future prices are quoted for every month of such years shall mean the price
calculated by taking the average of the NYMEX settlement prices on the Pricing
Date for each year or partial year (provided that if the first year of the
Reserve Report is a partial year, the NYMEX prices for months which are not
included in the Reserve Report will not be included in the average price
calculation for that year). For years in which NYMEX future prices are quoted
for some, but not all, of the months in the year, the Market Price shall be
calculated by first calculating interpolated prices for the months not quoted
and then averaging the NYMEX prices with those interpolated prices. For each
year in which NYMEX future prices are not quoted for any month, the Market
Price shall be calculated by taking the average of NYMEX settlement prices on
the Pricing Date for the last year for which NYMEX prices are quoted. An
example of Market Price calculations is attached as Exhibit 14.

          (iii) Reserves shall be adjusted to reflect revisions to volume 
estimates of reserves since the effective date of the last Reserve Report.

          (iv) Projected operating expenses shall be adjusted to reflect (i) 
actual expense levels incurred since the effective date of the last Reserve 
Report and (ii) projected increases or decreases in anticipated operating 
expense levels. Operating expenses will not be risked (reduced) when 
calculating Collateral Value.

          (v) Although the Reserve Report may include probable and possible
reserves, in calculating the Collateral Value, no value shall be given to such
probable and possible reserves, acreage or production equipment.

          (vi) Collateral Value shall be calculated net of  Lender's Interest.

     "Contract Operating Agreement" shall have the meaning assigned to such
term in the Schedule.

     "COPAS" shall mean The Accounting Procedure Joint Operations Recommended
by the Council of Petroleum Accountants.

relating to the maintenance, development and operation of such Property in an
amount not greater than the Working Interest of Borrower for the productive
life of such Property, as indicated on Exhibit 1 annexed hereto; and

interest which is not paid as a result of the limitation referred to in the
preceding sentence shall be carried forward and paid by Borrower to Lender on

     Closing Date.

9.   Borrower is not engaged in any joint venture or partnership with any other
     Person.

10.  No broker's or finder's fees or commissions have been paid or will be
     payable by Borrower or any Affiliate thereof to any Person in connection
     with the transactions contemplated by this Master Agreement. Borrower will
     indemnify Lender and its Affiliates and their respective officers,
     directors, employees and agents from and against, and hold each of such
     parties harmless on demand from, all liabilities, costs, damages and
     expenses, including, but not limited to, attorneys' fees and disbursements
     relating to any third parties concerning finder's, brokerage, financing or
     similar fees arising in connection with the transactions contemplated
     under this Master Agreement.

11.  Each of Borrower and Borrower's Parent has filed all tax returns (Federal,
     State or local) required to be filed and paid all taxes shown thereon to
     be due including interest and penalties or has provided adequate reserves
     (in accordance with GAAP) therefor. No assessments have been made against
     either Borrower or Borrower's Parent by any taxing authority nor has any
     penalty or deficiency been made by any such authority. No Federal or other
     income tax return of either Borrower or Borrower's Parent is presently
     being examined by the Internal Revenue Service or any State or local tax
     authority nor are the results of any prior examination by the Internal
     Revenue Service or any State or local tax authority being contested by
     either Borrower or Borrower's Parent. All ad valorem, property,
     production, excise, severance, windfall profit and similar taxes and
     assessments based on or measured by the ownership of property or the
     production or removal of Hydrocarbons or the receipt of proceeds therefrom
     from the Properties have been and will be timely paid. Borrower,
     Borrower's Parent and all predecessors in interest to any of the
     Properties have paid all taxes required to be paid by them such that no
     taxing authority has any right to assert any lien over or other interest
     in the Properties.

12.  No action or proceeding is now pending or is threatened against either
     Borrower or Borrower's Parent or any Named Operator with respect to the
     Properties, at law, in equity or otherwise, before any court, board,
     commission, agency or instrumentality of the Federal or State government
     or of any municipal government or any agency or subdivision thereof, or
     before any arbitrator or panel of arbitrators and neither Borrower nor
     Borrower's Parent nor any Named Operator has accepted liability for any
     such action or proceeding. There is no proceeding pending before any
     governmental agency (Federal, State or local) and, to the knowledge of
     each of Borrower and Borrower's Parent, no investigation has been
     commenced before any such government agency the effect of which, if
     adversely decided, would materially adversely affect or impair Borrower's,
     Borrower's Parent's or any Named Operator's respective business or
     financial condition.

13.  The Collateral is or will be owned by Borrower, and the Lender's Interest
     will be conveyed to Lender by Borrower, free and clear of any security
     interest, lien, encumbrance, mortgages, security agreement or other charge
     other than the Permitted Encumbrances and liens, mortgages and security
     interests and property interests which





                                     Page 21
   26
     are in favor of Lender and its Affiliates or are permitted hereunder.
     Borrower has Defensible Title to Borrower's Working Interest and/or Net
     Revenue Interest, and, if applicable, any Royalty Interest owned by
     Borrower, in the Properties, including each Lease related thereto. Except
     for Permitted Encumbrances, Borrower's Interest is not subject to any
     mineral reservations or top leases. Except for Permitted Encumbrances, and
     except for this Master Agreement and the Security Documents, there are no
     unrecorded documents or agreements which may result in impairment or loss
     of Borrower's or Lender's ability to convey the Property. Subject to the
     Permitted Encumbrances, Borrower has all beneficial right, title and
     interest in and to the Net Revenue Interest in all production from or
     allocable to Borrower's interest in the Properties (including each Lease)
     and has the exclusive right to sell the same subject to any right in the
     owners of Royalty Interests to take their royalty interest in kind.

14.  Upon consummation of the transactions contemplated hereunder and under the
     Security Documents, Borrower will have outstanding no Indebtedness in
     excess of the amount stated in the Schedule, other than the Term Loan,
     that is not specifically identified and disclosed to the Lender in the
     list of Permitted Encumbrances or the balance sheet referred to in Section
     4.6 above or Indebtedness incurred in the usual course of business since
     the date of such balance sheet.

15.  Borrower possesses, or will possess prior to the date on which each
     Property is fully operational, all trademarks, trade names, trade styles,
     copyrights and patents necessary to conduct its business relating to each
     of the Properties as it is presently conducted or as Borrower intends to
     conduct it hereafter without any infringement or conflict with the rights
     of any other Person.

16.  Borrower is not the lessor or lessee under any leases other than Leases
     included in the Properties and the lease on its principal executive office
     and except for any leases that are Permitted Encumbrances.

17.  Borrower (i) has not committed to make any Investment other than in
     connection with the Acquisition Agreements and/or Development Program,
     (ii) is not a party to any indenture, agreement, contract, instrument or
     lease or subject to any charter, by-law or other corporate restriction or
     any injunction, order, restriction or decree, which would materially and
     adversely affect its business, operations, properties or assets; (iii) is
     not a party to any "take or pay" contract or settlement or any other
     contract or agreement; or (iv) has no material contingent or long term
     liability or commitment which would materially affect its business that
     has not been disclosed to Lender in writing.

18.  On and after the Closing Date, Borrower and the applicable Operator will
     have all permits, licenses and other authorizations which are required
     under Environmental and Safety Regulations with respect to safety,
     pollution or protection of the environment relating to each Property,
     including laws relating to actual or threatened emissions,





                                    Page 22
   27
     discharges or releases of pollutants, raw materials, products,
     contaminants or hazardous or toxic materials or wastes into ambient air,
     surface water, groundwater or land, or otherwise relating to the
     manufacture, processing, distribution, use, treatment, storage, disposal,
     transport or handling of pollutants, contaminants or hazardous or toxic
     materials or wastes, the failure of which to obtain would materially and
     adversely affect the value, use or operation of any portion of the
     Property. Borrower is, and shall be and shall cause any Operator or agent
     with respect to any of the Properties to be, in compliance, in all
     material respects with all terms and conditions of such Environmental and
     Safety Regulations, and such permits, licenses and authorizations, and
     also in compliance in all material respects with all other limitations,
     restrictions, conditions, standards, prohibitions, requirements,
     obligations, schedules and timetables contained in such laws or contained
     in any regulation, code, plan, order, decree, judgment, notice or demand
     letter issued, entered, promulgated or approved thereunder relating to the
     Collateral, the failure to comply with which would materially affect the
     value, use or operation of any of the Properties. Borrower has not
     received notice of any violation of or investigation relating to any
     Environmental and Safety Regulations relating to any Property.

19.  All licenses, permits, operating authorities and other authorizations
     necessary to operate each of the Properties have been obtained and
     maintained. All such licenses, permits and authorizations are valid and in
     full force and effect. There are no pending fees, assessments or penalties
     relating to such permits, licenses and operating authorities. The
     continuation, validity and effectiveness of each such license, permit and
     other authorization are not and will in no way be adversely affected by
     the transactions contemplated by this Master Agreement, the Security
     Documents, the Lender's Interest Conveyance or the agreements as specified
     in the Schedule. Neither Borrower nor any Operator is in breach of, or in
     default under the terms of, and has not engaged in any activity which
     would cause revocation or suspension of, any such licenses, permits or
     authorizations and no action or proceeding looking to or contemplating the
     revocation or suspension of any thereof is pending or threatened against
     Borrower or any Operator. Neither Borrower nor any Operator is in
     violation of any law, ordinance, administrative or governmental rule or
     regulation or court decree relating to any of the Properties or otherwise
     applicable to Borrower.

20.  Neither Borrower nor any Operator is in violation of, or in default under,
     any material agreement in respect of any lease or any other contract or
     agreement to which it is a party or is bound.

21.  Borrower has not assumed, guaranteed or endorsed, or otherwise become
     directly or contingently liable in connection with, any liability of any
     other Person, except for the endorsement of checks and other negotiable
     instruments for collection in the ordinary course of business.

22.  The Security Documents and this Master Agreement constitute and will
     continue to





                                    Page 23
   28
     constitute a valid security interest in, and mortgage lien on, the
     Collateral and other assets covered thereby in accordance with Article III
     hereof, enforceable against Borrower and its successors and assigns, and
     securing the payment of all Obligations, purported to be secured thereby,
     and all filings and other actions necessary to perfect and protect such
     liens and security interests have been or will be duly taken.

23.  Except for the Permitted Encumbrances, there is no restriction or other
     limitation on Lender's right to obtain or exercise its security interests
     in the Equipment, including, without limitation, the right to foreclose on
     and sell such Equipment or to exercise all other rights and remedies of a
     secured party under the laws of each jurisdiction applicable to the
     Collateral other than Debtor Relief Laws, laws related to the rights of
     co-owners of property and laws related to the enforcement of security
     interests on personal property.

24.  Borrower has and, to Borrower's knowledge after diligent investigation,
     each Seller has, no unpaid bills for improvements to the Collateral that
     may give rise to mechanics', materialmen's or other similar liens arising
     by operation of applicable law should any such bills remain unpaid.

25.  Borrower is not engaged principally, or as one of its important
     activities, in the business of extending credit for the purpose of
     purchasing or carrying margin stock (within the meaning of Regulations G,
     U, or X of the Board of Governors of the Federal Reserve System). Neither
     Borrower nor any of its Affiliates or any person or entity acting on their
     behalf has taken any action which might cause this Master Agreement or the
     Term Notes to violate any of such Regulations G, T, U, or X, or any other
     regulation of the Board of Governors of the Federal Reserve System or to
     violate the Securities Exchange Act of 1934, in each case as now in effect
     or as the same may hereafter be in effect.

26.  Neither Borrower nor any Affiliate is a "holding company" or a "subsidiary
     company" of a "holding company" or an "affiliate" of a "holding company"
     or a "public utility" within the meaning of the Public Utility Holding
     Company Act of 1935, as amended.

27.  Neither Borrower nor any Affiliate is an "investment company" within the
     meaning of the Investment Company Act of 1940, as amended.

28.  There is no agreement in force and effect (including, without limitation,
     letters of intent), whether written or oral, between Borrower or any of
     its Affiliates with any Person regarding the acquisition or financing of
     any of the Properties and the purchase and sale of production from or
     allocable to the Properties, and no Person has any call upon, option to
     purchase or similar rights under any agreement with respect to Borrower's
     Working Interest and/or Net Revenue Interest in the Properties or to the
     production therefrom.

29.  No suit or other proceeding by any third party is pending or, to
     Borrower's knowledge after diligent investigation, threatened before any
     court or governmental agency seeking





                                    Page 24
   29
     to restrain, enjoin or prohibit or declare illegal, or seeking substantial
     damages from Borrower in connection with, the transactions contemplated by
     this Master Agreement.

30.  No approvals, filings or any other action is required under or pursuant to
     the H-S-R Act in connection with the transactions contemplated by this
     Master Agreement.

31.  Borrower has no employees on account of whom the Borrower or any Affiliate
     thereof (i) is required to comply in any respect with ERISA or (ii) could
     have any liability to any party under or in connection with ERISA.
     Borrower maintains no employee pension benefit plans or similar
     arrangements for any employees.

32.  All Wells are, in all respects, operated in compliance with all applicable
     rules, regulations, permits, judgments, orders and decrees of any court or
     the federal and state regulatory authorities having jurisdiction thereof.
     All of the Wells have been drilled and completed or are being drilled
     within the boundaries of the Lease or Leases for such Wells or within the
     limits otherwise permitted by contract, pooling or unit agreement and by
     law.

33.  With respect to the Properties, unit agreements, pooling agreements,
     commutization agreements, and other Basic Documents creating interests
     constituting the Properties, (i) Borrower has, and each Operator has, in
     all respects fulfilled all requirements including but not limited to, all
     filings, certificates, disclosures to parties in interest, and other
     similar matters contained in such leases, contracts or other documents (or
     otherwise applicable thereto by law, rule or regulation) granting or
     governing the operation or maintenance of the Properties, and Borrower is
     and will be fully qualified to own, hold and exercise such rights under
     such Property or other documents; (ii) except as set forth in the Schedule
     and Exhibit 12 hereto, there are no obligations to drill additional wells
     or to engage in other development operations, except for obligations
     arising under offset well provisions, obligations arising under provisions
     of Operating Agreements which allow the parties thereto to elect whether
     or not they will participate and obligations hereunder; provided, however,
     to Borrower's knowledge, there is no current proposal to drill any such
     wells or engage in other development operations; (iii) there are no
     limitations as to the depths covered or substances to which such interests
     purport to apply; (iv) there are no royalty provisions (other than those
     allowing a lessor the right to take in kind) requiring the payment of
     royalties on any basis other than as specified in the Lease or disclosed
     as a Permitted Encumbrance in Exhibit 1 hereto; and (v) the Leases and
     other interests will not expire on a date certain, nor after a specific
     number of years from some starting date.

34.  With respect to the joint, unit or other Operating Agreements relating to
     Borrower's Working Interest and/or Net Revenue Interest in the Properties
     there are no outstanding calls for payments under authorities for
     expenditures or payments which are due or which Borrower or any
     predecessor of Borrower has committed to make which have not been





                                    Page 25
   30
     paid, and there are no operations under the Operating Agreements with
     respect to which Borrower has become a non- consenting party nor are there
     any non-consenting penalties not reflected in the Net Revenue Interest or
     Working Interest of Borrower as indicated in Exhibit 1 hereto.

35.  All agreements applicable to Borrower's Working Interest and/or Net
     Revenue Interest in the Properties are of the type generally found in the
     oil and gas industry, do not (individually or in the aggregate) contain
     unusual provisions which may operate in an adverse manner with respect to
     Borrower's Working Interest in the Properties and/or Net Revenue Interest,
     and are in form and substance considered conventional within the oil and
     gas industry.

36.  Except as disclosed by Borrower to Lender in writing prior to execution of
     this Master Agreement, as of the Closing Date, none of the proceeds from
     the sale of Hydrocarbons produced from Borrower's Working Interest in the
     Properties and/or Net Revenue Interest are (i) subject to refund, (ii)
     subject to a "take or pay" contract in which the gas purchaser may take
     gas previously paid for or (iii) subject to balancing rights of third
     parties. Except as disclosed by Borrower to Lender in writing prior to
     execution of this Master Agreement, as of the Closing Date, all proceeds
     from the sale of Hydrocarbons from Borrower's Working Interest in the
     Properties and/or Net Revenue Interest are being received in all respects
     in a timely manner and are not being held in suspense for any reason.

37.  The proceeds of the Term Loan will be used only for the purposes set forth
     in Section 2.2 of the Schedule.

     4.38 The Lender's Interest Conveyance is enforceable against the Borrower
and its successors and assigns.

     4.39 With respect to the Basic Documents: (i) all are in full force and
effect in accordance with their terms and are valid and binding obligations;
(ii) all payments (including, without limitation, royalties, delay rentals,
shut-in royalties, and joint interest or other billings under unit or Operating
Agreements) due by Borrower thereunder have been made by Borrower; (iii) no
other party to any Basic Document (or any successor in interest thereto) is in
breach or default to Borrower's knowledge with respect to any of its
obligations thereunder; (iv) no party to any Basic Document has given or has
threatened to give notice of any action to terminate, cancel, rescind or
procure a judicial reformation of any Basic Document or any provision thereof;
and (v) the execution and delivery of this Master Agreement and the
consummation of the transactions contemplated hereby will not result in a
breach of, constitute a default under, or result in a violation of the
provisions of any Basic Document.

the Schedule.

to all leases subject thereto.

     4.42 Borrower has Defensible Title in the Property, free and clear of any
lien, claim or encumbrance except Permitted Encumbrances or arising under this
Master Agreement or the Security Documents.

in the ordinary course of business and otherwise in accordance with any
applicable Lease.

and outstanding shares of common stock, par value per share as listed in such
Exhibit 9 (the "Common Stock"), of Borrower, which constitute 100% of the
issued and outstanding shares of capital stock of Borrower. The Common Stock
have been duly and validly authorized and are fully paid and non-assessable.

     4.45 All representations and warranties of Borrower hereunder shall
survive any investigation by or on behalf of Lender until all Obligations to
Lender have been fulfilled by Borrower.

     deemed reasonably necessary of each Seller under each such Acquisition
     Agreement. Any other conditions necessary to the consummation of the
     transactions contemplated by the Acquisition Agreements (including,
     without limitation, the consent of any other Person) have been or will be
     satisfied or obtained.

2.   The Acquisition Agreements, annexed hereto as Exhibit 6 have not and will
     not be amended, terminated, rescinded or withdrawn, and no provisions
     thereof have been, or will be, waived by Borrower, without the written
     consent of Lender.

3.   Borrower has paid and will pay and perform all of its remaining
     obligations, if any, to the Sellers under the Acquisition Agreements.

4.   Insofar as it may have any rights against any Seller under the Acquisition
     Agreements or under any agreement or instrument constituting a part
     thereof, Borrower has used and will use prudent business judgment
     concerning its preservation of, and decisions whether to enforce, the same
     against such Seller.

5.   The Acquisition Agreements do not and will not grant any Seller or any
     other party a security interest, lien or other encumbrance on or in any
     Collateral, the Lender's Interest Conveyance, if any, or stock of
     Borrower.

6.   To Borrower's knowledge, neither the execution and delivery of the
     Acquisition Agreements nor the consummation of any of the transactions
     contemplated thereby constitute a breach of, or an event of default under,
     any contract or agreement to which any Seller is a party or by which they
     or their respective assets are bound, or constitute the happening of an
     event or condition upon which any other party to such a contract or
     agreement may exercise any right or option which will materially adversely
     affect any of Borrower's Working Interest and/or Net Revenue Interest in
     the Properties or the transfer

perform certain obligations to ensure compliance with these covenants, Borrower
shall, exercising all rights and remedies available to it under the terms of
the applicable Operating Agreements, cause such Operators to perform such

     Borrower's business. All Equipment shall be used in accordance with law
     and the manufacturer's instructions. Equipment shall not be removed from
     the applicable Property without Lender's prior written consent except in
     the ordinary course of





                                    Page 31

     Borrower's business.

3.   Where Borrower is permitted to dispose of any Equipment under this Master
     Agreement or by any consent thereto hereafter given by Lender, it shall do
     so, or shall cause any Operator to do so, at arm's-length, in good faith
     and by obtaining the maximum amount of recovery practicable therefor and
     without impairing the operating integrity of the remaining Equipment.


                                   ARTICLE 8.

that requires the Borrower to cause Operators that are not Affiliates of
Borrower to perform certain obligations to ensure compliance with these
covenants, Borrower shall, exercising all rights and remedies available to it
under the terms of the applicable Operating Agreements, cause such Operators to
perform such obligations and shall, to the extent such rights and remedies
available under the terms of the applicable Operating Agreements are
insufficient, use its best efforts in good faith to do each and every act and

     and rights, privileges and franchises in connection therewith and remain
     qualified to do business in every jurisdiction where the nature of its

     assets. Borrower will transact business in its own name;

2.   conduct transactions with any of its Affiliates on an arm's-length basis;

3.   pay and discharge, and cause any Operator to pay or discharge, all ad

     its business or to declare any substance contained in any product used,
     sold or distributed by Borrower to be dangerous;

7.   give Lender prompt written notice of any destruction or substantial damage
     to any of the Collateral causing a loss in excess of the amount specified

8.   maintain, and cause any Operator of any of the Properties to maintain, all
     authorizations, licenses, permits, charters and registrations necessary to

     Regulations;

10.  operate, and/or cause each Operator to so operate, any property owned by
     Borrower (whether or not such property constitutes a "facility" as defined

     CERCLA or other applicable Federal law or under any state, local or
     municipal law, statute (including, without limitation, Hazardous Substance
     Laws), ordinance, rule or regulation designed to protect the environment
     or relating to the disposition, generation or transportation of hazardous
     waste, which would constitute a lien or charge on any property of Borrower

     should nevertheless arise hereafter, Borrower will, at its own expense,
     immediately cure or cause a third party to immediately cure the same and
     indemnify and hold harmless Lender and its officers, directors, agents and
     employees from any liability, responsibility or obligation in respect





                                    Page 33
   38

     the Release of Hazardous Materials on, or from, any or all of the
     Properties, Borrower shall give and shall cause any Operator or agent to
     give prompt written notice thereof to Lender (and, in any event, prior to
     the expiration of any period in which to respond to such notice under any
     applicable Environmental and Safety Regulation);

12.  continuously keep, all of the Property insured by insurance companies
     licensed or approved to do business in the State of New York and the
     States where the Properties are located with a Best's rating of A or

     policy or policies of such insurance or certificates of insurance to
     Lender if Lender so requests and whether or not so delivered such policies
     and all proceeds thereof shall be security for all Obligations. All
     insurance proceeds received by Lender shall be retained by Lender at its

   40
     8.   The amounts of insurance required in this Section 8.12 may be
          satisfied by the purchase of separate Primary and Umbrella (or
          Excess) Liability policies which when combined together provide the
          total limits of insurance specified.

     9.   To the extent that any Operator has arranged for and bound insurance
          on behalf of Borrower to cover Borrower's Working Interest and Net

          Borrower is appropriately named as loss payee of such insurance, with
          standard Additional Insured Working Interest Owner endorsement and
          such insurance is acceptable to Lender; provided however Borrower
          shall be required to bind coverage under Sections (a), (b) and (d)

     force and effect in accordance with the provisions of this Master
     Agreement, (ii) such insurance is non-cancelable without at least thirty
     (30) days' prior written notice to Lender sent by United States registered

     authorities or others, including, without limitation, owners or holders of
     overriding royalty interests, net profit interests, production payments,
     or any other liens or burdens from or relating to the Property, where such
     non-payment would create any lien rights against any item of Collateral or
     otherwise interfere with or jeopardize performance by Borrower under this
     Master Agreement. In such case, Lender may, in its sole discretion, but
     need not, make such payments or agree to pay such persons as are required
     to enable Borrower to complete performance under this Master Agreement





                                    Page 36

     reasonable efforts as a prudent operator to timely perform the development
     and operation schedule as described in the Development Program attached as

     estimate of work to be done, each of which shall be supported by an AFE on
     material operations prior to the commencement thereof. Immediate notice
     shall be given by Borrower to Lender of any problem which may result in a
     significant diminution in, or cessation of, production or involve a
     significant risk of loss to the Net Revenue Interests in the Properties;

18.  so long as any Obligation remains unfulfilled or any Collateral remains
     located at any of the Properties or other facilities owned, leased, or
     used by Borrower, (i) accord, and cause each of the Operators to accord,
     Lender or its agent or consultants, including without limitation, the
     Engineers, full and unrestricted access to the Properties and such other
     facilities, to the financial and operational records of Borrower and each
     of the Operators and to any other facilities including pipelines, so as to

     business hours with such notice to Borrower as is reasonable under the
     circumstances, and in case (i) subject to reasonable safety restrictions
     and in accordance with custom in the industry and the applicable Operating
     Agreement. Borrower shall give Lender due notice of workovers and other
     field activities to permit Lender to exercise its rights under clause (i)
     above. Borrower will allow the Lender access to appropriate officers,
     employees and agents of Borrower to discuss the affairs, finances and
     accounts of Borrower at such reasonable times and as often as Lender may
     request, and will allow Lender to discuss with Borrower's officers,
     independent consultants, and Operators, and other Persons, and such
     Persons are hereby authorized to discuss with Lender, Borrower's business,

     Properties is in compliance with all applicable laws and requirements;

20.  in the event of a failure by any Operator to perform its obligations under

     the rights set forth in Section 10.6 hereof, immediately upon the request
     of Lender, remove such Operator or commence such proceedings as may be
     necessary under the applicable Operating Agreement to remove such Operator
     or assign to Lender or any of its Affiliates its right to remove any
     Operator with respect to the Properties, seek indemnification or damages
     from such party and its successors or assigns for any loss or liability
     incurred by Borrower and/or pay the owners of royalty interests directly
     and deliver and cause such Operator to deliver to any successor Operator
     all books, agreements, contracts, papers, records (including but not

     such Operator to take all steps, necessary to ensure such results as may
     be directed by such successor Operator; Borrower shall promptly reimburse
     Lender for all payments made, if any, pursuant to this Section 8.20 upon
     the occurrence of any non- performance under an Operating Agreement;

     not creditworthy, upon the request of Lender, Borrower shall (i) cause the
     relevant Operator to cause such Purchaser of Hydrocarbons to provide one
     or more letters of credit, in form, substance and from a bank satisfactory
     to Lender in connection with its purchase of Hydrocarbons from the
     Properties, (ii) cause the relevant Operator to sell Hydrocarbons only to
     Purchasers who are creditworthy in Lender's judgment, or (iii) exercise
     its right to take the Hydrocarbons in kind and sell to Purchasers of
     Hydrocarbons who are creditworthy in Lender's judgment;

22.  if the Forecast delivered by Borrower pursuant to section 5.9 indicates
     that the anticipated production attributable to the Properties is less
     than the Fixed Price Obligations for one or more months, but Borrower and
     Lender believe that the production allocable to the Properties will
     otherwise be equal to or greater than the aggregate Fixed Price
     Obligations, Borrower shall agree, if so requested by Lender, to adjust
     the schedule of the Fixed Price Obligations accordingly. Any gain or loss
     resulting from such adjustment shall be for the Borrower's account.


                                   ARTICLE 9.

                                  ARTICLE 10.

                            Further Rights of Lender

1.   Until the Loan Termination Date, Borrower, at its own expense, shall do
     all things and shall deliver all instruments requested by Lender to
     protect or perfect any security interest, mortgage or lien given hereunder
     or under any Security Documents, including, without limitation, financing
     statements under the Uniform Commercial Code. Borrower authorizes Lender
     to execute alone any financing statement or other documents or instruments
     that Lender may require to perfect, protect or establish any lien or
     security interest hereunder or under any Security Documents and further
     authorizes Lender to sign Borrower's name on the same. Borrower hereby
     authorizes Lender to appoint such Person or Persons as Lender may
     designate as its agent and attorney-in-fact to endorse the name of
     Borrower on any checks, notes, drafts or other forms of payment or
     security that may come into the possession of either Lender or any
     Affiliate of Lender, to sign Borrower's name on invoices or bills of
     lading, drafts against customers, notices of assignment, verifications and
     schedules and, generally, to do all things necessary to carry out this
     Master Agreement and the Security Documents. Upon the occurrence of an
     Event of Default, such agent and attorney-in-fact may also notify the Post
     Office authorities to change the address of delivery of mail to an address
     designated by Lender, and open and dispose of mail addressed to Borrower.
     The powers granted herein, being coupled with an interest, are
     irrevocable. Neither Lender nor the agent and attorney-in-fact shall be
     liable for any act or omission, error in judgment or mistake of law so
     long as the same is not malicious or grossly negligent. Upon payment and
     performance of all Obligations of Borrower to Lender, such power of
     attorney will become null and void.

2.   In the event that Borrower fails to purchase or maintain insurance (where
     applicable) in accordance with the requirements of this Master Agreement,
     or to pay any tax,





                                    Page 42
   47
     assessment, government charge or levy, except as the same may be otherwise
     permitted hereunder, or in the event that any lien, encumbrance or
     security interest prohibited hereby shall not be paid in full or
     discharged, or in the event that Borrower shall fail to perform or comply
     with any other covenant, promise or Obligation to Lender hereunder or
     under any related document, Lender may, but shall not be required to,
     perform, pay, satisfy, discharge or bond the same for the account of
     Borrower, and all monies so paid by Lender, including reasonable
     attorneys' fees and disbursements, shall be treated as an additional
     Obligation of Borrower to Lender hereunder or under any of the Security
     Documents.

3.   Borrower will pay all costs to be paid on taxes, assessments, governmental
     charges or private encumbrances levied, assessed, imposed or payable upon
     or with respect to the Collateral or any part thereof.

4.   Upon the occurrence of an Event of Default, Lender may (i) enter
     Borrower's premises or any other premises of the Borrower at which any
     books or records relating to the Borrower or the Properties are maintained
     at any time; and (ii) until it completes the enforcement of its rights in
     the Equipment or other Collateral subject to its security interest or lien
     hereunder and the sale or other disposition of any property subject
     thereto, take possession of such premises without charge, rent or payment
     therefor, or place custodians in control thereof, remain on such premises
     and use the same and any of Borrower's Equipment and other Collateral for
     the purpose of completing any work in process, preparing any Collateral
     for disposing of or collecting any Collateral.

5.   Borrower will indemnify Lender and its officers, directors, employees and
     authorized agents and hold each respective party harmless from and against
     any and all injuries, claims, damages, judgments, liabilities, costs and
     expenses (including, without limitation, fees and disbursements of
     counsel), charges and encumbrances which may be incurred by or asserted
     against Lender or any of its officers, directors, employees or authorized
     agents in connection with or arising out of any assertion, declaration or
     defense of Lender's rights or security interests under the provisions of
     this Master Agreement or any Security Document or in connection with (i)
     the acquisition or operation of the Collateral; (ii) the realization,
     repossession, safeguarding, insuring or other protection of the
     Collateral; (iii) the collecting, perfecting or protecting of Lender's
     liens and security interests hereunder; or (iv) any investigation,
     litigation, or proceeding related to any present or future acquisition
     (including, without limitation, the acquisition of the Properties from the
     respective Sellers) or proposed acquisition by Borrower. Borrower waives
     any right it might have in connection with any suit or action against
     Lender to claim special, indirect, consequential (unless due to Lender's
     sole and not concurrent gross negligence or willful misconduct), or
     punitive damages to it, its business or its prospects. Borrower has
     consulted with its counsel with respect to the provisions of this Section
     10.5 and understands that it is to be interpreted broadly against
     Borrower. Notwithstanding any other provision in this Master Agreement,
     the provisions of this Section 10.5 shall





                                    Page 43
   48
     continue in full force and effect and shall survive any cancellation,
     prepayment or payment in full of all of the Obligations hereunder.

6.   To the extent permissible under the Operating Agreements, Lender shall
     have the right to approve or disapprove any action taken by Borrower to
     appoint, remove or replace any Operator of any of the Properties.


                                  ARTICLE 11.

                               Remedies of Lender

1.   Upon the occurrence of any Event of Default, Lender may terminate this
     Master Agreement without prior notice or demand to Borrower or may demand
     payment of all Obligations (whether otherwise then payable on demand or
     not) without terminating this





                                    Page 49
   54
     Master Agreement and shall, in any event, be under no further
     responsibility to extend any credit or afford any financial accommodation
     to Borrower, whether under this Master Agreement or otherwise. The
     occurrence of an Event of Default shall constitute the Loan Termination
     Date, provided that Lender elects to terminate the Agreement or demand
     payment of all Obligations. Upon such termination of this Master Agreement
     following an Event of Default, Lender shall have, in addition to all of
     its other rights under this Master Agreement, any Security Document, by
     operation of law or otherwise (which rights shall be cumulative), all of
     the rights and remedies of a secured party under the Uniform Commercial
     Code and shall have the right to enter upon any premises where the
     Collateral is kept and peacefully retake possession thereof.

2.   Lender shall not have any obligation to preserve rights to any Collateral
     against prior parties or to proceed first against any Collateral or to
     marshal any Collateral of any kind for the benefit of any other creditor
     of Borrower or any other Person. Lender is hereby granted a license or
     other right to use, without charge, Borrower's labels, patents,
     copyrights, rights of use of any name, trade secrets, trade names,
     trademarks and advertising matter, or any property of a similar nature, as
     it pertains to the Collateral, in completing production of, advertising
     for sale, and selling any Collateral and Borrower's rights under all
     licenses and any franchise, sales or distribution agreements shall inure
     to Lender's benefit.

3.   Borrower shall pay all costs and expenses of amending, administering,
     implementing, perfecting, collecting, defending, declaring and enforcing
     Lender's rights, security interests in the Collateral hereunder or under
     any Security Document or other instrument or agreement delivered in
     connection herewith, including, without limitation, searches and filings
     at all times, and Lender's attorneys' fees (regardless of whether any
     litigation is commenced, whether default is declared hereunder, and
     regardless of tribunal or jurisdiction).

4.   Upon the occurrence of an Event of Default, Lender shall have the right to
     set-off and apply against the Obligations in such manner as Lender may
     determine, at any time to Borrower, any and all deposits (general or
     special, time or demand, provisional or final, other than deposits held by
     Borrower for the account of third parties and designated as such) or other
     sums at any time credited by or owing from Lender or any depositary to
     Borrower whether or not the Obligations are then due. Lender shall provide
     notice to Borrower not later than five days following any application of
     such funds. As further security for the Obligations, Borrower hereby
     grants to Lender a security interest in all money, instruments, and other
     property of Borrower now or hereafter held by Lender, including, without
     limitation, property held in safekeeping. In addition to Lender's right of
     set-off and as further security for the Obligations, Borrower hereby
     grants to Lender a security interest and lien in all deposits (general or
     special, time or demand, provisional or final) and other accounts of
     Borrower now or hereafter on deposit with or held by Lender or any
     depositary and all other sums at any time credited by or owing from Lender





                                    Page 50
   55
     or any depositary to Borrower. The rights and remedies of Lender hereunder
     are in addition to other rights and remedies (including, without
     limitation, other rights of set-off) which Lender may have.

5.   Upon the occurrence of an Event of Default, Lender shall have the right to
     exercise Borrower's rights under the Operating Agreements.


                                  ARTICLE 14.

                               General Provisions

1.   Lender's rights and remedies under this Master Agreement shall be
     cumulative and non-exclusive of any other rights or remedies which it may
     have under any other agreement or instrument, by operation of law or
     otherwise.

2.   This Master Agreement is entered into for the benefit of the parties
     hereto and their respective successors and assigns. It shall be binding
     upon and shall inure to the benefit of such parties and their respective
     successors and assigns.

3.   Borrower hereby agrees that in connection with any additional development
     work on the Properties, Lender shall have the right as outlined in the
     Schedule, but not the obligation, to extend credit to Borrower (such
     extension of credit being defined as an "Additional Loan") pursuant to the
     same terms and conditions as those contained in this Master Agreement and
     the related documents. In connection with such Additional Loan, Borrower
     will execute such documents and agreements in form and substance
     satisfactory to Lender as are necessary to evidence the Additional Loan
     and security therefor.

4.   Borrower will pay all of Lender's Closing Expenses and Lender's Post-
     Closing Expenses during the pendency of this Master Agreement, including
     the reasonable fees and out-of-pocket expenses of Lender's counsel(s) and
     any other consultant engaged by Lender in connection with the
     administration or enforcement of, or any amendments, modifications or
     waivers with respect to, this Master Agreement or any other agreement or
     instrument delivered in connection herewith, including but not limited to
     costs of search, recording taxes or fees, filing fees, and any other
     out-of-pocket expenses incurred by Lender.

5.   Any notice, demand or document which either party is required or may
     desire to give hereunder shall be in writing and, except to the extent
     provided in the other provisions of this Master Agreement, given by
     messenger, telex, telecopy or other electronic transmission, or United
     States registered or certified mail, postage prepaid, return receipt
     requested, addressed to such party at its address, telex and telecopy
     number shown in the Schedule, or at such other address as either party
     shall have furnished to the other by





                                    Page 51
   56
     notice given in accordance with this provision. Any notice delivered or
     made by messenger, telex, telecopy, or United States mail shall be deemed
     to be given on the date of actual delivery as shown by messenger receipt,
     the addressee's telex confirmation, the addressor's telecopy machine
     confirmation or other verifiable electronic receipt, or the registry or
     certification receipt. Lender need not delay action on notice transmitted
     orally until receipt of written confirmation of such notice. In the event
     that a discrepancy exists between the notice received by Lender orally and
     the written confirmation, or in the absence of a written confirmation, the
     oral notice, as understood by Lender will be deemed the controlling and
     proper notice.

6.   Neither the failure nor any delay on the part of any party hereto to
     exercise any right, remedy, power, privilege or option under this Master
     Agreement shall operate as a waiver of such or any other right, remedy,
     power, privilege or option. No single or partial exercise of any right,
     remedy, power, privilege or option under this Master Agreement shall
     preclude any other or further exercise thereof or the exercise of any
     other right, remedy, power, privilege or option. No waiver of any right,
     remedy, power, privilege or option with respect to any occurrence shall be
     construed as a waiver of such right, remedy, power, privilege or option
     with respect to any subsequent or other occurrence. No waiver whatever
     shall be valid unless in writing and signed by an officer of the party to
     whom such waiver applies and then only to the extent therein set forth.

7.   Except as may be required by law, rule or regulation or in response to
     legal process, and such filings as are necessary or appropriate to create,
     maintain and perfect liens and security interests contemplated hereby,
     Borrower shall not release this Master Agreement or any other document,
     agreement or instrument relating to or executed in conjunction with this
     Master Agreement, or disclose the substantive terms hereof or thereof,
     except to its attorneys, accountants or engineers on a need-to-know basis,
     without the prior express written consent of Lender. Without limitation of
     the foregoing, neither party or any of their respective Affiliates shall
     issue any press release or make any other public announcement relating to
     this Master Agreement without the written approval of the other party.

8.   This Master Agreement, including the Schedule, together with all exhibits
     annexed hereto, and the other agreements to which this Master Agreement
     refers, constitute the final, entire agreement among the parties hereto
     and supersede any and all prior oral or written and any and all
     contemporaneous oral proposals, commitments, promises, agreements and
     understandings between the parties with respect to the subject matter
     hereof and thereof, all of which are merged herein or therein and replaced
     hereby or thereby. It is expressly understood and agreed that this Master
     Agreement and the Security Documents to which Borrower is a party may not
     be terminated, waived, altered, amended, modified or otherwise changed in
     any respect or particular whatsoever except in writing duly executed by
     authorized representatives of the party to be charged.

     protest upon any instrument on which it may be liable to Lender as maker,
     endorser, guarantor or otherwise.

     DOCUMENTS GOVERNED BY THE LAWS OF THE STATE WHERE THE COLLATERAL IS
     LOCATED) . THE VALIDITY OF THIS MASTER AGREEMENT, THE TERM NOTES AND EACH
     OF THE SECURITY DOCUMENTS AND OF ALL TRANSACTIONS PROVIDED FOR HEREIN OR

     CONTROVERSY ARISES OUT OF OR RELATING TO THE MASTER AGREEMENT,
     REPRESENTATIVES OF THE BORROWER AND LENDER SHALL FIRST MEET IN NEW YORK,
     NEW YORK AND ATTEMPT TO NEGOTIATE A RESOLUTION OF THEIR DISPUTE. IN THE

     HAVE NO AUTHORITY TO AWARD PUNITIVE OR OTHER DAMAGES NOT MEASURED BY THE
     PREVAILING PARTY'S ACTUAL DAMAGES AND MAY NOT, IN ANY EVENT, MAKE ANY
     RULING, FINDING, OR AWARD THAT DOES NOT CONFORM TO THE TERMS AND
     CONDITIONS OF THE MASTER AGREEMENT. THE PARTIES SHALL FAITHFULLY OBSERVE
     THIS AGREEMENT AND SUCH RULES, AND WILL ABIDE BY AND PERFORM ANY AWARD
     RENDERED BY THE ARBITRATORS, AND A JUDGMENT OF ANY COURT HAVING
     JURISDICTION MAY BE ENTERED ON THE AWARD. THE PROVISIONS OF THIS SECTION
     RELATING TO ARBITRATION OF DISPUTES SHALL NOT APPLY TO THE ENFORCEMENT OF
     ANY RIGHTS OR OBLIGATIONS OR THE SETTLEMENT OF DISPUTES IN CONNECTION WITH
     THE SECURITY DOCUMENTS, AS TO WHICH THE DISPUTE RESOLUTION PROCEDURES WILL
     BE SUCH AS ARE SET FORTH IN SUCH SECURITY DOCUMENTS. IN ANY ACTION WHICH
     MAY BE INSTITUTED AGAINST BORROWER ARISING OUT OF OR RELATING TO THIS
     MASTER AGREEMENT, THE TERM NOTES, THE LENDER'S INTEREST CONVEYANCE, OR ANY
     OTHER SECURITY DOCUMENT, BORROWER HEREBY CONSENTS TO THE SERVICE OF
     PROCESS IN CONNECTION WITH ANY ACTION BY THE MAILING THEREOF BY REGISTERED
     OR CERTIFIED MAIL AT THE ADDRESS SET FORTH IN SECTION 14.5 OF THE
     SCHEDULE.

11.  Subject to Section 14.2 hereof, the benefits of this Master Agreement
     shall not inure to any third party. Notwithstanding anything contained in
     the Security Documents, or any conduct or course of conduct by the parties
     hereto, before or after signing the Security Documents, this Master
     Agreement shall not be construed as creating any rights, claims or causes
     of action against Lender, or any of its officers, directors, agents or
     employees by any Person other than Borrower.

     thereof of this Master Agreement held by a court of competent jurisdiction

     nullify the remainder of this Master Agreement, but the effect thereof
     shall be confined to the section, clause, subsection, sentence, paragraph
     or provision, or portion thereof so held to be invalid, illegal or
     ineffective.

13.  The headings, captions and arrangements contained in this Master Agreement
     have been inserted for convenience only and shall not be deemed in any
     manner to modify, explain, enlarge or restrict any of the provisions
     hereof.

14.  Borrower and Lender acknowledge that each of them has had the benefit of
     legal counsel of its own choice and has been afforded an opportunity to
     review this Master Agreement, the Term Notes and the other Security
     Documents with its legal counsel and that this Master Agreement and the
     other Security Documents shall be construed as if jointly drafted by
     Borrower and Lender.

     to execute and deliver or cause to be executed and delivered, such
     reasonable documents and instruments, and take such other reasonable and
     lawful action as the other party shall deem necessary or desirable to
     perfect or evidence perfection of its security interest, to enforce its
     obligations hereunder or to otherwise effectuate the purposes of this
     Master Agreement.

16.  Lender may assign, transfer or otherwise dispose of any of its rights or
     obligations hereunder without the prior written consent of Borrower
     provided that Borrower continues to deal only with Lender in regard to
     funding and reporting requirements hereunder and no assignment shall
     relieve Lender of its obligations hereunder. Borrower may not assign any
     of its rights or obligations hereunder without the prior written approval
     of Lender.

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

ARTICLE XIV  General Provisions

Section 14.3      Additional terms and conditions pursuant to Section 14.3 of 
                  the Master Agreement:

                  Until the earlier of (i) the date on which all amounts under
                  Tranche A and Tranche B have been drawn, or (ii) the date on
                  which all amounts drawn under Tranche A and Tranche B have
                  been repaid in full, Lender shall have the right of first
                  refusal to finance any future acquisition and/or development
                  of the Properties on the same terms and conditions set forth
                  herein so long as such development meets the criteria of
                  Tranche B herein. If Lender does not exercise its right to
                  finance any particular acquisition and/or development, then
                  Borrower may seek to obtain alternate financing, and Lender
                  agrees (A) to reconvey its Lender's Interest with respect to
                  additional Wells attributable to such future development and
                  (B) to release any mortgage it holds on such Wells (or
                  portions of the Properties) where such future development
                  will occur, in each case if and as necessary to permit
                  another financial institution or industry participant to
                  finance or fund such future development.

Section 14.4      It is understood in this Section 14.4 that Borrower is 
                  obligated to pay only up to $100,000 of Lender's Closing
                  Expenses.

Section 14.5      The last two sentences of Section 14.5 of the Master 
                  Agreement are deleted and replaced in their entirety with the
                  following:

                  "Lender need not delay action on notice transmitted orally by
                  Borrower until receipt of written confirmation of such
                  notice. In the event that a discrepancy exists between the
                  notice received by Lender orally and the written
                  confirmation, or in the absence of a written confirmation,
                  the oral notice, as understood by Lender will be deemed the
                  controlling and proper notice until written confirmation is
                  received."
