<PAGE>

     1.   All of Westtide's right, title and interest (including but not
     limited to working interests, royalty interests and overriding royalty
     interests) in and to the oil and gas leases and mineral interests described
     in Exhibit "A," attached hereto and made a part hereof for all purposes,
     and the wells described in Exhibit "B," attached hereto and made a part
     hereof for all purposes (the above described interest in such leases and

     restrictions, exceptions, reservations, conditions, limitations, burdens,
     contracts, agreements and other matters applicable to the Leases and the
     Wells;

     2.   All of Westtide's right, title and interest in and to, or derived
     from, the following insofar and only insofar as same are attributable to

          (a)  All presently existing and valid oil, gas or mineral unitization,
     pooling, operating and communitization agreements, declarations and orders
     affecting the Leases and Wells, with respect to the properties covered and
     the units created thereby (the "Units");

          (b)  The personal property and fixtures that are appurtenant to the
     Leases, the Wells and the Units, including all wells, casing, tubing,

II.  Payment and Closing
     -------------------

     1.   Penalty Payments. Paragraph 1.a. of each of the Options establishes
     certain penalty payments to exercise the Options prior to January 1, 2003
     (the "Penalty Payments"). Upon the execution of this Agreement and the
     conclusion of the Closing contemplated hereunder, HSR shall have no further
     obligation to Westtide for the Penalty Payments.

                                       4
<PAGE>

     2.   Option Price. Paragraph 5 of each of the Options establishes the
     Option Price to exercise the Option. The Option Price is the estimated
     current fair market value of Westtide's interest in the Interests
     (post-Westtide Production Payment tail net of the Reversion Interest) to be
     purchased. The parties agree that the current fair market value of
     Westtide's interest in the Interests as of the Option Effective Date plus
     the Penalty Payments is equal to the sum of the value of (i) the Option
     Exercise Production Payment, and (ii) the Option Exercise Price Payment(as
     defined below).

     3.   Option Exercise Production Payment. HSR hereby grants to Westtide a
     production payment interest in and to the production of Subject
     Hydrocrabons (including, but not limited to, any Subject Hydrocarbons
     resulting from hydraulic fracture restimulation of the Wells) from the
     Leases, such that, commencing with the calendar quarter which includes the
     Option Effective Date, HSR shall make payments to Westtide within sixty
     (60) days following the end of each calendar quarter in an amount equal to
     $0.8385 of each dollar of tax credits available to HSR under Section 29 of
     the Internal Revenue Code of 1986, as amended (the "Code) as a result of
     the sale of Subject Hydrocarbons produced from the Wells during such
     calendar quarter (determined without regard to limitations on HSR's use of
     the credits imposed by Section 29(b)(6) of the Code and without regard to
     whether HSR has sufficient income to actually use such credits or in fact
     utilizes such credits), through that calendar quarter which ends on
     December 31, 2002 (the "Option Exercise Production Payment"). Payments from
     HSR to Westtide under the Option Exercise Production Payment shall be
     limited to and made only from the proceeds of production from the Subject
     Hydrocarbons. HSR shall have no obligation to make payments to Westtide on
     any tax credits which may be available to HSR after December 31, 2002, even
     if the provisions of Section 29 of the Code are extended beyond December
     31, 2002. Payments on the Option Exercise Production Payment shall be
     computed and made by HSR to Westtide in the same manner that Westtide was
     required to make payments to HSR under the Purchase Agreements. Any
     outstanding payment under the Option Exercise Production Payment which is
     due and owing shall bear interest at the rate of eighteen percent (18%) per
     annum, compounded daily, from the date the payment is due until the date
     the payment is received by Westtide. The obligation to make payments on the
     Option Exercise Production Payment shall survive the Closing of this
     Agreement and shall continue until all of the payments due with respect to
     the production of Subject Hydrocarbons from the Option Effective Date
     through and until December 31, 2002 have been paid to and received by
     Westtide. Upon receipt of all payments due under the Option Exercise
     Production Payment, Westtide shall execute and deliver to HSR a recordable
     instrument evidencing satisfaction and termination of the Option Exercise
     Production Payment.

     4.   Closing and Assignment. The closing of the purchase of the
     Interests pursuant to the exercise of the Options shall occur at the
     offices of HSR on April 3, 2001 (the "Closing"). Upon full execution and
     delivery of this Agreement, HSR will deliver by wire transfer a payment to
     Westtide (the "Option Exercise Price Payment") in the amount of
     $8,816,176.00. For the convenience of the parties hereto, this Agreement
     and all related documents may be signed and transmitted to Davis Graham &
     Stubbs LLP prior to April 3, 2001, but shall be held in escrow and deemed
     not delivered until the Closing occurs on April 3, 2001.

III. Cancellation of Recourse Notes
     ------------------------------

     HSR hereby cancels and terminates as of the Option Effective Date the
Recourse Notes. HSR delivers herewith to Westtide the originals of each of the
Recourse Notes, each marked "CANCELED, PAID IN FULL," evidencing the full and
complete satisfaction of the obligations thereunder by Westtide, and the waiver
and release hereunder by HSR of any unsatisfied obligations therein of Westtide.

IV.  Termination of Westtide Production Payment Obligations
     ------------------------------------------------------

     HSR hereby releases Westtide of all liability with respect to the Westtide
Production Payments due on the production of Subject Hydrocarbons occurring
after the Option Effective Date.

V.   Termination of FMR Guaranties
     -----------------------------

     HSR hereby releases FMR Corp. of all liability for its obligations under
the FMR Guaranties, and HSR and Westtide hereby terminate the FMR Guaranties as
of the Option Effective Date.

VI.  Termination of Management Agreements
     ------------------------------------

     Westtide and HSR hereby terminate the Management Agreements; provided,
however, that all obligations of HSR to maintain insurance which identifies
Westtide as an additional insured shall continue through the Option Effective
Date, and provided further, that the obligation of HSR for indemnification of
Westtide under the Management Agreements shall survive the termination of the
Management Agreements. HSR hereby waives any and all claims and causes of action
it has or may have against Westtide under the Management Agreements and
acknowledges that its authority as Attorney-in-Fact of Westtide with respect to
the Interests under the respective Management Agreements is hereby extinguished.

VII. Representations and Covenants.
     -----------------------------

     1.   HSR hereby ratifies and confirms all of its representations and
     warranties under each Purchase Agreement regarding the qualification of the
     Subject Hydrocarbons for the tax credits available under Section 29 of the
     Code . The rights of Westtide under the Purchase Agreements shall survive
     the Closing, and Westtide shall be entitled to enforce all of the remedies
     under the Purchase Agreements for any failure of any of the Subject
     Hydrocarbons to satisfy any such qualification requirements.

     2.   Notwithstanding the termination of the Management Agreements, HSR
     covenants that for all Subject Hydrocarbons produced during the period from
     the Option Effective Date until December 31, 2002, HSR will provide
     Westtide with reports at the same time payments are made on the Option
     Exercise Production Payment, and such reports shall be sufficient to
     support the computation of the payment and the underlying tax credits
     available to HSR during such quarter. Westtide shall have the right to
     audit the books

                                       6
<PAGE>

     and records (including federal income tax returns) of HSR with respect to
     the production and sales of Subject Hydrocarbons from the Wells and Leases
     and the tax credits associated therewith from the effective date of the
     respective Purchase Agreement until December 31, 2004.

     3.   Within sixty (60) days after the Option Effective Date, HSR and
     Westtide shall reconcile and set off the outstanding amounts due between
     them on any and all (i) Prepaid Credit Amounts, (ii) Credit Payment Amounts
     which have accrued and are due and owing based on sales of Subject
     Hydrocarbons through March 31, 2001, and (iii) overpayments of Credit
     Payment Amounts with respect to the Subject Hydrocarbons produced prior to
     the Option Effective Date. The reconciliation of such amounts shall be
     documented by a written statement signed by both parties, and the resulting
     net payment after set off shall occur by wire transfer of immediately
     available funds to the party to whom such net payment is due.

     4.   If at any time following the execution and delivery of this
     Agreement but prior to July 1, 2002, HSR determines that it cannot utilize
     the tax credits available under Section 29 of the Code with respect to the
     sale of Subject Hydrocarbons, HSR and Westtide covenant to enter into good
     faith negotiations for a period of thirty (30) days following HSR's written
     notification to Westtide of such determination in an effort to monetize the
     value of the tax credits available through December 31, 2002 on terms
     substantially similar to those under the Purchase Agreements. Neither HSR
     nor Westtide shall be bound to enter into any such agreement.

     5.   HSR represents and warrants that the Interests are not subject to
     any preferential right, consent to assignment, or similar limitation on
     transfer, except to the extent previously disclosed by HSR to Westtide
     pursuant to the Purchase Agreements. HSR shall indemnify, defend, save and
     hold harmless Westtide and its affiliates, officers, directors, successors
     and assigns from any claim or cause of action related to or arising from
     any preferential right, consent to assignment or similar limitation on
     transfer affecting this Agreement and HSR further waives any claim or cause
     of action it might have against Westtide in any way related to such
     preferential right, consent to assignment, or similar limitation on
     transfer.

VIII. Miscellaneous.
      -------------

     1.   The Credit Payment Amount overpayment provisions set forth in each
     Purchase Agreement shall not be amended, waived or limited in any way by
     the terms of this Agreement and the rights of Westtide under the Purchase
     Agreements shall survive the Closing.
