2.4      Deposit

         Purchaser has paid to Sellers a performance guarantee deposit (the
         "Deposit") in an amount equal to One Million Dollars ($1,000,000),
         which Deposit has been deposited contemporaneously herewith in an
         interest-bearing escrow account with Bank of Oklahoma, N.A. (the
         "Deposit Escrow") pursuant to an escrow agreement in the form attached
         hereto as Exhibit J (the "Deposit Escrow Agreement"). If Closing
         occurs, (i) the Deposit Escrow shall be terminated, and (ii) the
         Deposit, together with interest earned thereon, shall be delivered into
         a separate escrow account with Bank of Oklahoma, N.A. pursuant to
         Section 2.6 below to serve as the Holdback Amount. If this Agreement is

                  equity. The parties agree that the damages that would be
                  suffered by Sellers as a result of Purchaser's breach would be
                  difficult to estimate and that the liquidated damages
                  described herein represent a reasonable estimation of such
                  damages and do not constitute a penalty.

         (b)      If Closing does not occur for any reason or circumstance other
                  than that described in Section 2.5(a), the Deposit together
                  with all interest earned thereon shall be returned to the
                  Purchaser.

         (c)      At Closing, Purchaser shall pay to Sellers or as directed by
                  Sellers by wire transfer the Purchase Price, adjusted as
                  provided in Article 4 below and less and except the Deposit
                  (together with interest earned thereon) to the account or
                  accounts designated by Sellers.

2.6      Holdback

         At Closing, the Deposit Escrow shall be terminated and the Deposit,
         together with interest earned thereon (the "Holdback Amount"), shall be
         deposited into an escrow account with Bank of Oklahoma, N.A. (the
         "Holdback Escrow Account") and held pursuant to an escrow agreement in
         the form attached hereto as Exhibit K to be executed at Closing
         ("Holdback Escrow Agreement") for a period expiring ninety (90) days
         after the Closing Date (unless extended pursuant to Sections 10.1
         and/or 10.2 below), for the purpose of securing (i) Purchaser's rights
         post-Closing to seek a Due Diligence Reduction pursuant to Section 10.3
         below, and (ii) the limited indemnity obligations of Sellers as set
         forth in Section 7.1 below. All portions of the Holdback Amount with
         respect to which no claim has been made by Purchaser on or before the
         Final Settlement Date (or such later date, if the escrow is extended
         pursuant to Sections 10.1 and/or 10.2 below) shall be promptly released
         to Sellers pursuant to the Holdback Escrow Agreement.

                  (v)      revenues from the sale of Petroleum Substances will
                           be deemed to accrue when the Petroleum Substances are
                           produced;

                  (vi)     all rentals and similar payments in respect of the

4.2      Imbalances, Prepayments and Refunds

         The Parties recognize that as of the Effective Time there may be (i)
         gas imbalances ("Imbalances") with respect to production from or
         attributable to certain of the Assets, whether such Imbalances be
         instances of overproduction ("Imbalance Obligations") or
         underproduction ("Imbalance Entitlements"), and including, without
         limitation, the imbalances set forth in Schedule G), (ii) prepayment
         obligations due to monies received by Sellers under production sales
         contracts or similar agreements containing "take-or-pay" clauses (or
         similar arrangements), whereby Sellers are obligated to deliver oil or
         gas produced after the Effective Time with respect to an Asset without
         receiving payment therefor in the ordinary course of business
         ("Prepayment Obligations"), or (iii) refund obligations arising from
         Sellers' sale of oil or gas produced from an Asset prior to the
         Effective Time at prices exceeding the applicable maximum lawful prices
         ("Refund Obligations"). The Parties agree that, from and after the date
         of this Agreement, they shall jointly attempt to ascertain prior to
         Closing all Imbalances, Prepayment Obligations and Refund Obligations
         affecting the Assets as of the Effective Time. The Parties further
         agree that they shall adjust the Purchase Price at Closing for all
         discovered Imbalances, Prepayment Obligations and Refund Obligations in
         accordance with the following procedures:

         (a)      Imbalances. The value of discovered Imbalances (including,
                  without limitation, those set forth in Schedule G existing as
                  of the Effective Time shall be calculated by multiplying the
                  overproduced or underproduced volumes by $1.05 per Mcf. At
                  Closing or on the Final Settlement Date, as the case may be,
                  the Purchase Price shall be adjusted upward for the aggregate
                  value of all Imbalance Entitlements and downward for the
                  aggregate value of all Imbalance Obligations. Respecting
                  Imbalances discovered after the Final Settlement Date,
                  Purchaser shall bear all obligations with respect to any
                  overproduction liability and shall receive the benefit of and
                  be credited with any underproduction credit, including
                  overproduction and underproduction attributable to periods of
                  time prior to the Effective Time.

         (b)      Prepayment Obligations. At Closing or on the Final Settlement
                  Date, as the case may be, the Purchase Price shall be adjusted
                  downward by all amounts received by Sellers prior to the
                  Closing with respect to Prepayment Obligations.

         (c)      Refund Obligations. At Closing or on the Final Settlement
                  Date, as the case may be, the Purchase Price shall be adjusted
                  downward by all amounts received by Sellers prior to the
                  Closing with respect to Refund Obligations.



                                       14


4.3      Suspense Accounts

         The parties agree that all suspended royalties and other proceeds which
         are held by Sellers (or by a third-party designee on behalf of Sellers)
         in suspense for third parties attributable to production from the
         Assets shall be transferred to Purchaser at the Closing. As of February
         28, 2004, the aggregate amount of such suspended royalties is
         $124,766.00. Purchaser shall and does hereby assume responsibility for
         the payment of all suspended revenues to third parties entitled to the
         same and shall and does hereby hold Sellers harmless from and against
         any loss, liability, cost or expense (other than those that may be
         attributed to Sellers' improper placement of such revenues in suspense)
         which might arise from claims of third parties asserted following
         Sellers' transfer to Purchaser of the suspended revenues pursuant to
         this Section 4.3.

4.4      Adjustments to Account

         (a)      An interim accounting of the adjustments pursuant to Sections
                  4.1 and 4.2 shall be made at Closing, based on (i) Sellers'
                  good faith estimate and Purchaser's verification of the costs
                  and expenses paid by Sellers prior to Closing and the revenues
                  received by Sellers prior to Closing, and (ii) the
                  quantification of Imbalances, Prepayments and Refunds existing
                  as of the Effective Time and confirmed by the Parties pursuant
                  to Section 4.2 above. Sellers shall provide a statement
                  setting forth the adjustments to be made at Closing not later
                  than three (3) Business Days prior to Closing and shall assist
                  Purchaser in verifying the amounts set forth in such
                  statement. A further accounting of the adjustments pursuant to
                  Sections 4.1 and 4.2 shall be conducted on or before the Final
                  Settlement Date. Any adjustment due from a Party for which
                  such Party has received written notice not later than the
                  Final Settlement Date, shall be settled by payment by such
                  Party required to make payment hereunder within 15 days of
                  being notified of the determination of the amount owing.

         (b)      During the 90 day period following the Closing Date, Purchaser
                  may audit the books, records and accounts of Sellers
                  respecting the Assets, for the purpose of effecting
                  adjustments pursuant to this Article. Such audit shall be
                  conducted upon reasonable notice to Sellers at Sellers'
                  offices during Sellers' normal business hours, and shall be
                  conducted at the sole expense of Purchaser; provided, that
                  Sellers shall supply such documentation as Purchaser
                  reasonably requests to support Sellers' proposed final
                  accounting.

(c)               All adjustments provided for in this Article 4 shall be
                  adjustments to the Base Price.

4.5      Limitation on Adjustments

         NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, NEITHER PARTY
         SHALL BE ENTITLED TO, OR LIABLE FOR, ANY ADJUSTMENTS PURSUANT TO THIS
         AGREEMENT (INCLUDING THIS ARTICLE 4) UNLESS WRITTEN NOTICE OF SUCH
         ADJUSTMENT HAS BEEN RECEIVED BY THE PARTY LIABLE TO MAKE PAYMENT (OR
         NET PAYMENT) IN RESPECT OF SUCH ADJUSTMENT(S) NOT LATER THAN THE FINAL
         SETTLEMENT DATE.

                  assumed by Purchaser that cannot be terminated without penalty
                  on notice from Sellers of 30 days or less. Sellers have
                  entered no hedging arrangements for the sale of Petroleum
                  Substances which would affect the Properties (or the sale or

                  respects, and (ii) there are no Assets which are subject to
                  gas balancing agreements containing a provision that would
                  require cash balancing upon the transfer of the affected Lease
                  or Well through a transaction of the nature contemplated in
                  this Agreement. There are no Take or Pay Obligations related
                  to the Assets;

         (n)      Environmental Matters. To Sellers' knowledge, Sellers have
                  given Purchaser access to all written information in its
                  possession relating to Environmental Liabilities and
                  Abandonment and Reclamation Obligations and, except as
                  otherwise disclosed in writing to the Purchaser prior to the
                  execution of this Agreement, Sellers have not received actual
                  notice, written or oral, received by any officer of the
                  Sellers, of:

                  (i)      any material non-compliance in relation to the Assets
                           of which Sellers is the operator with any law
                           intended to protect the environment which has not
                           been remedied in all material respects; or

                  (ii)     any claim in relation to the Assets by any Party of
                           material Environmental Liabilities (including
                           pollution) (or material Abandonment and Reclamation
                           Obligations).

         (o)      Affiliate Agreements. Sellers are not subject to any agreement
                  (other than agreements relating to assets that are unrelated
                  to the Assets purchased herein) with an Affiliate of any of
                  the Sellers that cannot be terminated by Purchaser after
                  Closing without penalty, cost or liability. For purposes
                  hereof, "Affiliate" shall mean (i) any person directly or
                  indirectly owning, controlling or holding with power to vote

                  shareholder of any Seller, (iii) any person directly or
                  indirectly controlling, controlled by or under common control
                  with any Seller or shareholder of any Seller, (iv) any

         which such Preferential Purchase Right exercised shall be excluded from
         the sale and the Base Price shall be reduced by the Allocated Value for
         such excluded Asset. An Asset which is excluded from the Assets as the
         result of this Section 9.2 shall not be used in calculating the
         Termination Amount and the Termination Amount shall be calculated
         utilizing such reduced Base Price. In the event a Person elects to
         exercise its Preferential Purchase Right to purchase a Asset but such
         sale has not been consummated prior to the Closing under this
         Agreement, Purchaser shall pay Sellers the Allocated Value of such
         Asset and Seller shall assign to Purchaser the Asset and Purchaser
         shall take the Asset subject to the Preferential Purchase Right and
         will have the right to receive the proceeds from the Preferential
         Purchase Right sale.

                      TITLE REVIEW AND ENVIRONMENTAL REVIEW

10.1     Title Review

         Between the execution of this Agreement and the Closing, subject to
         contractual and fiduciary obligations and limits, Sellers shall make
         available to Purchaser and its representatives all title documents
         (including contracts, correspondence, files and prior title opinions)
         in its possession pertaining to the Assets for purposes of permitting
         Purchaser to review Seller's title to the Assets. Purchaser shall
         conduct its review of Seller's title to the Assets with reasonable
         diligence. If there are Title Defects affecting the Assets, Purchaser
         shall give written notice of such Title Defects to Sellers and Sellers
         shall use reasonable efforts to cure such Title Defects prior to
         Closing. Such notice shall specify such Title Defects in reasonable
         detail, the Assets directly affected thereby and Purchaser's reasonable
         requirements for rectification or curing thereof, including the
         proposed adjustment to the Base Price based, in large part, upon the
         Allocated Value for each such Asset. In no event shall the adjustment
         to the Base Price for any particular Asset resulting from a Title
         Defect exceed the Allocated Value for such Asset. Purchaser's title
         review shall continue after Closing and Purchaser shall have a
         continuing right to assert Title Defects until the Final




                                       25




         Settlement Date, provided that (i) Title Defects asserted by Purchaser
         after Closing and agreed to by Sellers shall be handled between the
         Parties through the post-Closing accounting pursuant to Section 4.4(a)
         above, (ii) Title Defects asserted by Purchaser prior to the Final
         Settlement Date, but not agreed to by Sellers, will be subject to
         arbitration pursuant to Article 11 below, and (iii) the Holdback Escrow
         will be extended beyond the Final Settlement Date to the extent
         necessary to accommodate any arbitration initiated by a Party, except
         that those portions of the Holdback Amount remaining in escrow on the
         Final Settlement Date which are not at issue in the arbitration shall
         be released to Sellers. For all purposes, Purchaser shall be deemed to
         have asserted Title Defects as to any and all Pending Claims that have
         not been finally settled or otherwise resolved by Sellers prior to
         Closing.

10.2     Environmental Review

         Between the execution of this Agreement and the Closing, subject to
         contractual and fiduciary obligations and limits, Sellers shall make
         available to Purchaser and its representatives all documents (including
         contracts, correspondence and files) in its possession relating to the
         Assets and will allow Purchaser site access reasonably necessary for
         purposes of permitting Purchaser to evaluate the potential for
         existence of any Environmental Liabilities. Purchaser shall conduct its
         environmental review with reasonable diligence. If there are potential
         Environmental Liabilities, Purchaser shall give written notice of such
         potential Environmental Liabilities to Sellers. Such notice shall
         specify the Asset and the potential Environmental Liabilities in
         reasonable detail. Purchaser shall have the right to continue its
         environmental review after Closing and until the Final Settlement Date,
         provided that (i) Environmental Liabilities asserted by Purchaser after
         Closing and agreed to by Sellers shall be handled between the Parties
         through the post-Closing accounting pursuant to Section 4.4(a) above,
         (ii) Environmental Liabilities asserted by Purchaser prior to the Final
         Settlement Date, but not agreed to by Sellers, will be subject to
         arbitration pursuant to Article 11 below, and (iii) the Holdback Escrow
         will be extended beyond the Final Settlement Date to the extent
         necessary to accommodate any arbitration initiated by a Party, except
         that those portions of the Holdback Amount remaining in escrow on the
         Final Settlement Date which are not at issue in the arbitration shall
         be released to Sellers.

10.3     Valuation Resulting from Review

         (a)      Purchaser shall, acting reasonably, make a valuation of:

                  (i)      the amount by which the value of the Assets is
                           reduced by Title Defects identified in the notice
                           contemplated in Section 10.1 that have not been cured
                           to Purchaser's reasonable satisfaction; and

                  (ii)     the estimated reduction in the value of the Assets
                           associated with the Environmental Liabilities in
                           Section 10.2, provided that, when determining the
                           value impact of Environmental Liabilities:

                           (A)      the costs associated with ordinary course
                                    Abandonment and Reclamation Obligations
                                    relating to the Wells and the Tangibles
                                    shall not be considered except, and only to
                                    the extent that, such costs are forecast to
                                    be materially higher than a prudent
                                    purchaser would have expected them to be
                                    prior to conducting its due diligence; and



                                       26


                           (B)      where the particular Environmental
                                    Liabilities relate to matters which a
                                    prudent operator in the United States
                                    upstream oil and gas industry would, if
                                    aware of such Environmental Liabilities, not
                                    be legally required to commence remediation
                                    operations in respect thereof within twelve
                                    (12) months of the Closing Date, such
                                    Environmental Liabilities shall be deemed to
                                    have no adverse impact on the value of the
                                    Assets.

         and shall provide notice of such valuation to Sellers not later than
         ten (7) days before the Closing Date, or Final Settlement Date, as
         applicable. If Sellers do not agree with the Purchaser's valuations of
         the amounts contemplated in paragraphs 10.3(a)(i) and (ii), Sellers may
         submit the matter to arbitration in accordance with Article 11. The
         arbitration amount shall be the differential amount between the
         valuation determined by the Sellers and the valuation determined by the
         Purchaser. The aggregate amount ultimately agreed by the Parties or
         determined by arbitration shall be referred to herein as the "Due
         Diligence Reduction". If the Parties cannot agree on the value of the
         Due Diligence Reduction prior to Closing but both of them agree (acting
         reasonably) that it is less than ten percent (10%) of the Base Price,
         and all other conditions precedent to Closing have been satisfied, then
         the Purchase Price payable by Purchaser to Sellers at Closing shall
         reflect the Due Diligence Reduction as calculated by Sellers; and,
         after Closing, the Holdback Amount held in escrow shall serve to secure
         Purchaser's potential entitlement to the difference between Purchaser's
         valuation of the Due Diligence Reduction and Sellers' valuation of the
         Due Diligence Reduction. The Parties' respective entitlements to such
         disputed funds shall be resolved by arbitration pursuant to Article 11,
         and the escrowed funds comprising the Holdback Amount shall be paid
         from the escrow account as directed by the arbitrator or as otherwise
         agreed by the Parties.

         (b)      If the Due Diligence Reduction is, in the aggregate, less than
                  one and one-half percent (1.5%) of the Base Price, Purchaser
                  shall be deemed to have waived such Title Defects and accepted
                  such Environmental Liabilities; provided, however, that such
                  1.5% monetary threshold shall not be applicable to Title
                  Defects that are Pending Claims.

         (c)      If the Due Diligence Reduction is equal to or greater than one
                  and one-half percent (1.5%) of the Base Price but less than
                  ten percent (10%) of the Base Price, the Base Price shall be
                  reduced by the amount of such Due Diligence Reduction.

         If the Due Diligence Reduction is (i) quantified and sought by
         Purchaser prior to Closing, and (ii) equal to or greater than ten
         percent (10%) of the Base Price, the Base Price shall be reduced by the
         amount of such Due Diligence Reduction, provided that either Sellers or
         Purchaser will then have the right to terminate this Agreement such
         that Closing shall not occur. If both Parties nevertheless agree to
         proceed to Closing, the Base Price shall be



                                       27




         reduced by the amount of such Due Diligence Reduction. If the Parties
         cannot agree on the value of the Due Diligence Reduction and at least
         one of them values it (acting reasonably) at ten percent (10%) of the
         Base Price or more and the Parties agree to proceed to Closing, the
         Purchase Price payable to by Purchaser to Sellers at Closing shall
         reflect the Due Diligence Reduction as calculated by Sellers; and,
         after Closing, the Holdback Amount held in escrow shall serve to secure
         Purchaser's potential entitlement to the difference between Purchaser's
         valuation of the Due Diligence Reduction and Sellers' valuation of the
         Due Diligence Reduction. The Parties' respective entitlements to such
         disputed funds shall be resolved by arbitration pursuant to Article 11,
         and the escrowed funds comprising the Holdback Amount (and any interest
         that has accrued thereon) shall be paid as directed by the arbitrator
         or as otherwise agreed by the Parties. Absent agreement of the Parties
         to proceed to Closing as a result of only one of them valuing the Due
         Diligence Reduction at an amount equal to or greater than ten percent
         (10%) of the Base Price, the other Party may refer the matter of the
         value of the Due Diligence Reduction to arbitration pursuant to Article
         11.

         (d)      For the avoidance of doubt, any Due Diligence Reduction on the
                  Final Settlement Date is expressly limited to the lesser of
                  (i) the Holdback Amount, or (ii) the amount which, when
                  combined with the sum of the Due Diligence Reductions made at
                  Closing, is equal to the Termination Amount.

10.4     Inspection and Testing

         Purchaser waives and releases all claims against Sellers, and each of
         their respective directors, officers, employees, agents and other
         representatives and their successor and assigns for injury to or death
         of persons, or damage to property, arising in any way from the exercise
         of rights granted to Purchaser hereby or the activities of Purchaser or
         its employees, agents or contractors on the Assets. PURCHASER SHALL
         INDEMNIFY THE SELLERS AND EACH OF THEIR RESPECTIVE DIRECTORS, OFFICER,
         EMPLOYEES, AGENTS AND OTHER REPRESENTATIVES AND THEIR SUCCESSORS AND
         ASSIGNS AGAINST AND HOLD EACH AND ALL OF SAID INDEMNITEES HARMLESS FROM
         ANY AND ALL LOSSES WHATSOEVER ARISING OUT OF (I) ANY AND ALL STATUTORY
         OR COMMON LAW LIENS OR OTHER ENCUMBRANCES FOR LABOR OR MATERIALS
         FURNISHED IN CONNECTION WITH SUCH TESTS, SAMPLINGS, STUDIES OR SURVEYS
         AS BUYER MAY CONDUCT WITH RESPECT TO THE ASSETS; AND (II) ANY INJURY TO
         OR DEATH OF PERSONS OR DAMAGE TO PROPERTY OCCURRING IN, ON OR ABOUT THE
         ASSETS AS A RESULT OF SUCH EXERCISE OR ACTIVITIES.

                                   ARBITRATION

11.1     Selection

         Any disagreement, difference or dispute between Sellers and Purchaser
         under this Agreement shall be resolved by arbitration in accordance
         with this Article 11. In the event arbitration to resolve a dispute is
         necessary, Sellers and Purchaser agree to jointly select, an individual
         who (i) is acknowledged by the Parties as being an expert with respect
         to the oil and gas, land and legal issues and/or environmental issues,
         as applicable, (ii) who has at least ten (10) years experience in the
         oil and gas industry, and (iii) is independent of the Parties and/or
         their counsel, which individual shall be the sole arbitrator to hear
         and decide all matters that are subject to arbitration pursuant to this
         Article 11. If Sellers and Purchaser are unable to mutually agree on
         such individual, then the Sellers and Purchaser shall each select an
         individual who qualifies as an arbitrator and who will in turn select
         an individual to act as arbitrator.



                                       28


11.2     Location.

         Any arbitration hearing shall be held in Houston, Texas or at such
         other location as mutually agreed by the Parties.

11.3     Rules.

         The arbitrator shall settle all disputes in accordance with the Rules
         of the American Arbitration Association. The decision of the arbitrator
         shall be final and binding on the Parties, and, if necessary, enforced
         in any court of competent jurisdiction. Sellers and Purchaser,
         respectively, shall bear their own legal fees and other costs incurred
         in presenting their respective cases to the arbitrator. The charges and
         expenses of the arbitrator shall be shared equally by Sellers and
         Purchaser.

11.4     Time.

         The arbitration shall commence within ten (10) days after selection of
         the arbitrator. In the case of a dispute over a Due Diligence Reduction
         the arbitrator shall be selected in accordance with Section 11.1 within
         five (5) days after Closing or the Final Settlement Date, as
         applicable. Each Party shall have five (5) days to present its position
         on the issues being arbitrated. In fulfilling his duties, the
         arbitrator shall be bound by the terms and provisions contained herein
         but may consider such other matters as in the opinion of the arbitrator
         are necessary or helpful to make a proper determination. Additionally,
         the arbitrator may consult with and engage disinterested Party experts
         to advise the arbitrator, including without limitation, petroleum
         engineers and consultants. The arbitrator shall issue its final
         determination of all issues on or before thirty (30) days after the
         Parties have completed their presentation of the issues.

11.5     Replacement.

         If any arbitrator selected hereunder should die, resign or otherwise be
         unable to perform his or her duties hereunder, the procedure set forth
         in this Article 11 shall be used to select a replacement arbitrator.

                                  OPERATORSHIP

12.1     Transfer of Operatorship

         Purchaser acknowledges that Sellers may not be able to transfer
         operatorship of some or all of the Assets to Purchaser at or after
         Closing. Sellers covenants with Purchaser that Sellers shall do such
         reasonable things as Purchaser may request in order to obtain the
         appropriate consents and approvals for the assignment and transfer to
         Purchaser of operatorship of those of the Assets which Sellers
         currently operates.

12.2     Removal of Signs

         From and after Closing and upon written notice to Purchaser, Sellers
         may remove any signs which indicate its ownership or operation of the
         Assets. Purchaser will be responsible to erect or install signs
         required by governmental agencies to indicate that Purchaser is the
         operator of the Assets and to notify other working interest owners, gas
         purchasers, suppliers, contractors, governmental agencies and other
         Third Parties of Purchaser's interest in the Assets on and after
         Closing.

                                   TERMINATION

13.1     Causes of Termination

This Agreement and the transactions contemplated herein may be terminated:

         (a) At any time by mutual consent of the Parties;

         (b) By Purchaser and Sellers, if the Closing shall not have occurred by
April 30, 2004, despite the good faith reasonable efforts of the Parties, and if
the Party desiring to terminate is not in breach of this Agreement;

         (c) By either Party, if the Due Diligence Reduction quantifiable by
Closing is equal to or exceeds ten percent (10%) of the Base Price (the
"Termination Amount");

         (d) By Buyer if, on the Closing Date, any of the conditions set forth
in Section 5.1 shall not have been satisfied or waived; or

         (e) By Seller if, on the Closing Date, any of the conditions set forth
in Section 5.2 shall not have been satisfied or waived.

         In the event of the termination of this Agreement pursuant to the
provisions of this Article 13 or elsewhere in this Agreement, this Agreement
shall become void and have no further force and effect and, except for the
indemnities provided for in Section 10.4, any breach of this Agreement prior to
such termination and any continuing confidentiality requirement, no Party shall
have any further right, duty or liability to the other hereunder. Upon
termination, Purchaser agrees to use its best efforts to return to Seller or
destroy, all materials, documents and copies thereof provided, obtained or
discovered in the course of any due diligence investigations.

         hereby waived.

                    Pending or Threatened Lawsuits and Claims


1.   BIA-BLM Roye #1, Roye #2, Burge #1. Sections 30 and 31, Township 8 North,
     Range 21 East, Haskell County, Oklahoma. Wilshire had not paid gas
     royalties or had underpaid them on these wells from July 1993 through 2003.
     The principal already paid is $17,315.33. Penalty and interest will
     eventually be demanded by the MMS. MC5253A

2.   ONEOK Energy Resources. Wilhite #1-35. Section 35-23N-26W, Ellis County,
     Oklahoma. There was an allocation problem on a central point meter into
     which the Wilhite and an offsetting well were producing. The problem
     related back to January of 1999. ONEOK has stated that Wilshire was
     overpaid for 123,705 mcf. Settlement talks are ongoing. No lawsuit has been
     filed to date. 0.2.939.5

3.   Greka Energy. Richfield East Dome Unit, Orange County, California. Greka
     has failed and refused to pay Wilshire (San Francisco Oil Company) for oil
     and gas production from January of 2000 through September of 2002. Average
     monthly revenue received from October of 2002 through May of 2002 was
     approximately $750.00 per month. 0.2.583.1

4.   W. Plack Carr. Dunagan "A" #1. Ongoing claim for cash balancing by
     underproduced royalty owner. Wilshire offered interim cash balancing in

     since mid- 2003 to see if Wilshire has been sold. 0.2.431

5.   Coowners. Cestos Prospect, Dewey County, Oklahoma. Wilshire needs to
     provide updated over-and-short reports on the Blaine #1-29, the Blaine

on behalf of itself and the other Sellers. CCE, each of the Sellers and Escrow
Agent sometimes individually may be referred to as a "Party" and collectively
may be referred to as the "Parties."


                                    RECITALS

         A. CCE and the Sellers have entered into a Purchase and Sale Agreement
dated as of March 17, 2004, but effective for all purposes as of March 1, 2004
(the "Purchase Agreement").

         B. Pursuant to the Purchase Agreement, CCE will place One Million
Dollars ($1,000,000.00) in escrow (the "Escrow Amount") with Escrow Agent.

         C. Each of CCE and the Sellers desire to establish an escrow with
Escrow Agent to provide for the retention, administration and controlled access
of the Escrow Amount.

                                    AGREEMENT

         NOW, THEREFORE, in consideration of the premises and mutual agreements
and covenants contained in this Agreement, and including to be legally bound
hereby, the Parties agree as follows:

                                   ARTICLE 1.
                             ESTABLISHMENT OF ESCROW

         1.1 Appointment of Escrow Agent. Each of CCE and the Sellers hereby
appoint and direct Escrow Agent to act as escrow agent in accordance with the
terms of this Agreement, and the Escrow Agent hereby accepts such appointment.

         1.2 Deposit of Escrow Amount.

            (a) Upon the execution of this Agreement, CCE has deposited or
caused to be deposited the Escrow Amount into an account established by Escrow
Agent. The Escrow Amount shall be held and disposed of by Escrow Agent in
accordance with the terms and conditions of this Agreement.






            (b) Each of CCE and the Sellers hereby authorize and direct the
Escrow Agent to keep and preserve the Escrow Amount in its possession, free and
clear of any and all claims, liens and encumbrances whatsoever, subject to the
terms of this Agreement regarding the disbursement of all or part of such Escrow
Amount.

         1.3 Investment of Escrow Amount. Escrow Agent shall be permitted, and
is hereby authorized to deposit, transfer, hold and invest the Escrow Amount,
including principal and interest, in a money market fund managed by Escrow
Agent, during the period of this escrow in accordance with such instructions and
directions as may from time to time be provided to Escrow Agent in writing and
signed by CCE and WEI (on behalf of the Sellers). Any interest received by
Escrow Agent with respect to the Escrow Amount, including reinvested interest
("Interest"), shall become part of the Escrow Amount. The Interest earned on the
Escrow Amount shall be distributed in accordance with the terms of this
Agreement.

         1.4 Tax Related Terms.

            (a) Tax Reporting. CCE and the Sellers agree that, for tax reporting
purposes, all Interest or other taxable income earned from the investment of the
Escrow Amount in any tax year shall be taxable to the Party who receives such
Interest under this Agreement or under the escrow agreement with Bank of
Oklahoma, N.A. established pursuant to Section 2.1(c) below.

            (b) Certification of Tax Identification Number. CCE within 30 days
after the date hereof, shall provide Escrow Agent with certified tax
identification numbers by furnishing appropriate forms and documents that the
Escrow Agent may reasonably request. CCE understands that if such tax reporting
documentation is not so certified to Escrow Agent, then Escrow Agent may be
required by the Internal Revenue Code of 1986, as amended, to withhold a portion
of any Interest or other income earned on the investment of the Escrow Amount
pursuant to this Agreement.

            (c) Tax Allocation. To the extent that the Escrow Agent becomes
liable for the payment of any taxes in respect of income derived from the
investment of the Escrow Amount, Escrow Agent shall satisfy such liability to
the extent possible from the Escrow Amount and the Interest. Each of CCE and the
Sellers agree to indemnify and hold the Escrow Agent harmless from and against
any taxes, additions for late payment, interest, penalties and other expenses
that may be assessed against the Escrow Agent on or with respect to any payment
or other activities under this Agreement unless any such tax, addition for late
payment, interest, penalties and other expenses shall arise out of or be caused
by the actions of, or failure to act by, the Escrow Agent.

                                   ARTICLE 2.
                            RELEASE OF ESCROW AMOUNT

Purchase Agreement along with evidence that a copy of such certificate has been
delivered to CCE in accordance with Section 6.2 of this Agreement.

            (c) Escrow Agent shall, pursuant to Section 2.4 of the Purchase
Agreement, retain the Escrow Amount, together with Interest thereon as the
Holdback Amount (as defined in the Purchase Agreement) upon receipt of joint
written instructions signed by each of CCE and WEI (on behalf of the Sellers)
certifying that Closing (as defined in the Purchase Agreement) has occurred and
specifying that the Holdback Escrow Agreement (as defined in the Purchase
Agreement) has been executed by CCE and the Sellers.

            (d) Notwithstanding anything herein to the contrary, upon the
receipt of joint written instructions signed by each of CCE and WEI (on behalf
of the Sellers), Escrow Agent shall deliver the Escrow Amount, or portions
thereof and inclusive of Interest thereon, in accordance with such instructions.

                                   ARTICLE 3.
                              TERM AND TERMINATION

terminated by joint instructions in writing from CCE and WEI (on behalf of the
Sellers).

         3.2 Termination for Nonpayment. In the event of the nonpayment of fees
owed to Escrow Agent, Escrow Agent shall provide written notice of delinquency
to CCE and WEI (on behalf of the Sellers). Any Party to this Agreement shall
have the right to make the payment to Escrow Agent to cure the default. If the
past due payment is not received in full by Escrow Agent within 30 days of the
date of such notice, then Escrow Agent shall have the right either to (a)
terminate this Agreement at any time thereafter by sending written notice of
termination to CCE and WEI (on behalf of the Sellers), or (b) cure the default
by deducting the unpaid and owing fees from (i) the Interest and (ii) if the
amount of Interest is insufficient, by deducting the remainder from the Escrow
Amount. Escrow Agent shall have no obligation to take any action under this
Agreement so long as any payment due to Escrow Agent remains unpaid.

survive the termination or expiration of this Agreement.

                                   ARTICLE 4.
                               ESCROW AGENT'S FEES

         4.1 Fee Schedule. Escrow Agent is entitled to be paid its standard fees
and expenses applicable to the services provided. Escrow Agent shall notify CCE
and WEI (on behalf of the Sellers) for payment of Escrow Agent's fees at least
sixty (60) days prior to any increase in fees. For any service not listed on
Escrow Agent's standard fee schedule, Escrow Agent will provide a quote prior to
rendering the service, if requested.

         4.2 Payment Terms. Escrow Agent shall not be required to perform any
service unless the payment for such service and any outstanding balances owed to
Escrow Agent are paid in full. All invoiced fees shall be payable out of
Interest; provided, that any fees in excess of accrued Interest shall be paid
one-half (1/2) by CCE and one-half (1/2) by the Sellers. Late fees on past due
amounts shall accrue at the rate of __________ percent per month (__% per annum)
from the date of the invoice.

                                   ARTICLE 5.
                             LIABILITY AND DISPUTES

         5.1 Right to Rely on Instructions. Escrow Agent may act in reliance
upon any instruction, instrument, certificate or signature reasonably believed
by Escrow Agent to be genuine. Escrow Agent shall only act upon written notice,
request or instruction given by the designated contacts of a Party to this
Agreement. Escrow Agent shall not be responsible for failure to act as a result
of causes beyond the reasonable control of Escrow Agent.

         5.2 Indemnification. Escrow Agent shall be responsible to perform its
obligations under this Agreement and to act in a reasonable and prudent manner
with regard to this escrow arrangement. Provided Escrow Agent has acted in the
manner stated in the preceding sentence, CCE and the Sellers each agree to
indemnify, defend and hold harmless Escrow Agent from any and all claims,
actions, damages, arbitration fees and expenses, costs, attorney's fees and
other liabilities incurred by Escrow Agent relating in any way to this
Agreement.

         5.3 Disputes. If any disagreement or dispute arises between the Parties
to this Agreement concerning the meaning or validity of any provision hereunder
or concerning any other matter relating to this Agreement, the Escrow Agent
shall be under no obligation to act, except under process or order of court, or
until it has been adequately indemnified to its full satisfaction, and shall
sustain no liability for its failure to act pending such process, court order or
indemnification; and may, in its sole discretion, interplead the Escrow Amount
or that portion of the Escrow Amount it then holds with the District Court of
Harris County, Texas, and name the Parties in such action. Upon filing the
interpleader action, the Escrow Agent shall be relieved of all liability as to
the Escrow Amount and shall be entitled to recover from the Parties, its
reasonable attorneys fees and other costs incurred in commencing and maintaining
such action. In no event shall the institution of such interpleader action
impair the rights of the Escrow Agent set forth in Section 5.3 above.

                            HOLDBACK ESCROW AGREEMENT


         THIS ESCROW AGREEMENT (the "Agreement"), is made and entered into as of

ENTERPRISES, INC., a Delaware corporation ("WEI"), SAN FRANCISCO OIL COMPANY, a
California corporation ("SFO"), ROCKLAND RESOURCES, CO., an Oklahoma corporation
("RRC"), BRITALTA VENEZOLANO, LTD., an Alberta private corporation ("BV",
together with WEI, SFO and RRC, the "Sellers"), and BANK OF OKLAHOMA, N.A.
("Escrow Agent"). For all purposes herein, WEI shall act on behalf of itself and
the other Sellers. CCE, each of the Sellers and Escrow Agent sometimes
individually may be referred to as a "Party" and collectively may be referred to
as the "Parties."

                                    RECITALS

         A. Purchaser and Sellers have entered into a Purchase and Sale
Agreement dated as of March __, 2004, but effective for all purposes as of March
1, 2004 (the "Purchase Agreement");

         B. The Purchase Agreement provides for, among other things, a Sellers'
limited indemnity, indemnifying Purchaser from and against certain claims and
losses that may be asserted against or incurred by Purchaser as well as setting
forth procedures after Closing for addressing title defects and environmental
liabilities.

         C. As security for the limited indemnity obligation of Sellers and the
rights of Purchaser after Closing to address title defects and environmental
liabilities under the Purchase Agreement, the Parties have agreed that a
holdback amount equal to the earnest money (together with interest thereon),
previously escrowed under the Purchase Agreement, remain in an escrow fund (as
defined below); and

         D. The Escrow Agent has agreed to hold such funds pursuant to the terms
of this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements and covenants hereinafter set forth, the parties hereby agree as
follow

         1. Holdback Escrow Fund.

                  (a) On the date hereof, Purchaser and Sellers, by written
         instructions to the Escrow Agent, have directed that the Deposit (as
         defined in the Purchase Agreement) (together with interest thereon), in
         the amount of $1,000,000 plus accrued interest (the "Holdback Amount")
         in immediately available funds (as increased by any earnings thereon
         and as reduced by any disbursements or losses on investments, the
         ("Holdback Escrow Fund"), remain in escrow in accordance with this
         Agreement. The Escrow Agent hereby acknowledges receipt thereof.




                  (b) The Escrow Agent hereby agrees to act as escrow agent and
         to hold, safeguard and disburse the Holdback Escrow Fund pursuant to
         the terms and conditions hereof. Subject to and in accordance with the
         terms and conditions hereof, Escrow Agent agrees that it shall receive,
         hold in escrow, invest and reinvest and release or distribute the
         Holdback Escrow Fund. It is hereby expressly stipulated and agreed that
         all interest and other earnings on the Holdback Escrow Fund shall
         become a part of the Holdback Escrow Fund for all purposes, and that
         all losses resulting from the investment or reinvestment thereof from
         time to time and all amounts charged thereto to compensate or reimburse
         the Escrow Agent from time to time for amounts owing to it hereunder
         shall from the time of such loss or charge no longer constitute part of
         the Holdback Escrow Fund.

         2. Investment of the Holdback Escrow Fund. Escrow Agent shall invest
and reinvest the Holdback Escrow Fund, including principal and interest, in a
money market fund managed by Escrow Agent, during the period of this escrow and
unless otherwise instructed in writing by Purchaser and Sellers. Such written
instructions, if any, shall specify the type and identity of the investments to
be purchased and/or sold and shall also include the name of the broker-dealer,
if any, any particular settlement procedures required, if any (which settlement
procedures shall be consistent with industry standards and practices), and such
other information as Escrow Agent may require. Escrow Agent shall not be liable
for failure to invest or reinvest funds absent sufficient written direction.
Unless Escrow Agent is otherwise directed in such written instructions, Escrow
Agent may use a broker-dealer of its own selection, including a broker-dealer
owned by or affiliated with Escrow Agent or any of its affiliates. The Escrow
Agent or any of its affiliates may receive compensation with respect to any
investment directed hereunder. Escrow Agent shall not be liable for losses on
any investments, including, but not limited to, losses from market risks due to
premature liquidation or resulting from other actions taken pursuant to this
Escrow Agreement.

         3. Release of Holdback Escrow Funds. The Escrow Agent shall release the
Holdback Escrow Fund as follows:

                  (a) The Escrow Agent shall release the Holdback Escrow Fund in
         accordance with the written instructions of both Purchaser and Sellers
         (written instructions by either Purchaser or the Sellers acting
         independently shall not be sufficient to release the Holdback Escrow
         Fund).




                  (b) Purchaser may, from time to time, submit a demand to
         Sellers, with a copy to the Escrow Agent, specifying any claim (a
         "Claim") against Sellers made pursuant to Section 7.1 or Article 10 of
         the Purchase Agreement, and if known, the amount of the Claim, and
         certifying that Purchaser is entitled to payment from Sellers with
         respect to such Claim pursuant to the terms of Section 7.1 or Article
         10, as applicable, of the Purchase Agreement (a "Notice of Claim").
         Upon agreement among Purchaser and Sellers as to the validity and value
         of a Claim or upon a final determination by the Arbitrator as set forth
         in Article 11 of the Purchase Agreement as to the validity and amount
         of a Claim, Purchaser and Sellers shall submit a notice in writing
         signed by both Purchaser and Sellers (a "Payment Notice") to the Escrow
         Agent, setting forth the amount of payment due from Sellers that
         Purchaser is entitled to pursuant to the Purchase Agreement (the
         "Payment Amount"), with a copy of the Payment Notice to Sellers. The
         Escrow Agent shall release the Payment Amount to Purchaser pursuant to
         the terms of the Payment Notice.

                  (c) Unless the Escrow Agent shall have received a Notice of
         Claim from Purchaser that has not been paid or otherwise resolved on or
         before the Final Settlement Date (as defined in the Purchase
         Agreement), the Escrow Agent shall distribute the Holdback Escrow Fund
         (or, if pending Notice(s) of Claim specify a maximum Claim, and the
         Holdback Escrow Fund exceeds the amount of such Claim, the Escrow Agent
         shall distribute such excess) to Sellers.

                  (d) On or after the Final Settlement Date (as defined in the
         Purchase Agreement) and for each outstanding Claim that is resolved, to
         the extent the Holdback Escrow Fund exceeds the Payment Amount for such
         resolved Claim plus the maximum amount of Claims subject to any
         unresolved Notice of a Claim, the Escrow Agent shall distribute such
         excess to Sellers.

                  (e) Upon resolution and payment (if necessary) after the Final
         Settlement Date (as defined in the Purchase Agreement) of all
         outstanding Notices of Claim, the Escrow Agent shall distribute the
         Holdback Escrow Fund to Sellers.

                  (f) The Escrow Agent shall release the Holdback Escrow Fund in
         accordance with the terms of an order, judgment or decree of a court or
         administrative agency of competent jurisdiction ordering the release of
         the Holdback Escrow Fund or any portion thereof, accompanied by an
         opinion of counsel of the party requesting release of the Holdback
         Escrow Fund to the effect that such order, judgment or decree
         represents a final adjudication of the rights of the parties hereto by
         a court of competent jurisdiction, and that the time for appeal from
         such order, judgment or decree has expired without an appeal having
         been perfected.

         4.       Matters Relating to the Escrow Agent.

                  (a) Indemnification of Escrow Agent. Purchaser and Sellers,
         jointly and severally, agree to hold the Escrow Agent harmless and to
         indemnify the Escrow Agent against any loss, liability, expense
         (including reasonable attorney's fees and expenses), claim, or demand
         arising out of or in connection with the performance of its obligations
         in accordance with the provisions of this Agreement, except for gross
         negligence or willful misconduct of the Escrow Agent. The foregoing
         indemnities in this paragraph shall survive the resignation of the
         Escrow Agent or the termination of this Agreement.




                  (b) Specific Duties: No Liability. The Escrow Agent's duties
         are only such as are specifically provided herein, and the Escrow Agent
         shall incur no liability whatsoever to Purchaser or Sellers, except for
         gross negligence or willful misconduct. The Escrow Agent shall have no
         responsibility hereunder other than to follow faithfully the
         instructions herein contained. The Escrow Agent may consult with
         counsel and shall be fully protected in any action taken in good faith
         in accordance with such advice. The Escrow Agent shall be fully
         protected in acting in accordance with any written instructions given
         to it hereunder and believed by it to have been executed by the proper
         parties.

                  (c) Fees. The Escrow Agent shall be entitled to a fee of
         _______________________ Dollars ($______________) for the services
         rendered under this Agreement, which fee shall be paid from interest
         and other earnings on the Holdback Amount; provided that any fees in
         excess of accrued interest and earnings shall be paid by Sellers and
         Purchaser in equal shares. The Escrow Agent shall have a lien on the
         Holdback Escrow Fund for all expenses and fees incurred by it pursuant
         to this Agreement and shall have the right to reimbursement for all
         such expenses and fees from the Holdback Escrow Fund. If the Escrow
         Agent believes it to be reasonably necessary to consult with counsel
         concerning any of its duties hereunder, or if the Escrow Agent becomes
         involved in litigation as a result of acting as Escrow Agent hereunder,
         then in either case, the costs, expenses, and reasonable attorneys fees
         of the Escrow Agent shall be borne equally by the Purchaser and the
         Sellers.

                  (d) Disputes. It is understood and agreed that should any
         dispute arise with respect to the payment, ownership, or right of
         possession of the Holdback Escrow Fund, the Escrow Agent is authorized
         and directed to retain in its possession, without liability to anyone,
         all or any part of such funds until such dispute shall have been
         settled either by mutual agreement by the parties concerned or by the
         making of a final written arbitration award rendered in an arbitration
         proceeding conducted pursuant to Article 11 of the Purchase Agreement,
         but the Escrow Agent shall be under no duty whatsoever to institute or
         defend any such proceedings.

                  (e) Resignation. The Escrow Agent may resign at any time by
         giving written notice thereof to the other Parties, but such
         resignation shall not become effective until a successor escrow agent
         shall have been appointed and shall have accepted such assignment in
         writing. If an instrument of acceptance by a successor escrow agent
         shall not have been delivered to the Escrow Agent within 30 days after
         the giving of such notice of resignation, the resigning Escrow Agent
         may at the expense of the other parties hereto petition any court of
         competent jurisdiction for the appointment of a successor escrow agent.
