performance of this Agreement. Further, in the event that Buyer is requested or
required (by deposition, interrogatory, request for documents, subpoena, civil
investigative demand or similar process) to disclose any of the information,
Buyer shall provide Seller with prompt written notice of such request or
requirement, so that Seller may seek such protective order or other appropriate
remedy as it may desire. Buyer shall further take whatever reasonable steps
which may be necessary to ensure that Buyer's employees, consultants and agents
comply with the provisions of this Section 6.3.

      6.4. Inspections.

      Promptly after the execution of this Agreement and until Closing, Seller,
subject to any necessary third-party operator approval, shall permit Buyer and
its representatives at reasonable times and at their sole risk, cost and
expense, to conduct reasonable inspections of the Assets.

      6.5. No Warranty or Representation on Seller's Information.

      EXCEPT AS EXPRESSLY PROVIDED IN THIS AGREEMENT, SELLER MAKES NO WARRANTY
OR REPRESENTATION, EXPRESS OR IMPLIED, WITH RESPECT TO THE ACCURACY,
COMPLETENESS, OR MATERIALITY OF THE INFORMATION, RECORDS, AND DATA NOW,
HERETOFORE, OR HEREAFTER MADE AVAILABLE TO BUYER IN CONNECTION WITH THE ASSETS
OR THIS AGREEMENT, INCLUDING, WITHOUT LIMITATION, ANY DESCRIPTION OF THE ASSETS,
QUALITY OR QUANTITY OF HYDROCARBON RESERVES, IF ANY, PRODUCTION RATES,
RECOMPLETION OPPORTUNITIES, DECLINE RATES, GAS BALANCING INFORMATION, ALLOWABLES
OR OTHER REGULATORY MATTERS, POTENTIAL FOR PRODUCTION OF HYDROCARBONS FROM THE
ASSETS, OR ANY OTHER MATTERS CONTAINED IN OR OMITTED FROM ANY OTHER MATERIAL
FURNISHED TO BUYER BY SELLER. ANY AND ALL SUCH DATA, INFORMATION AND MATERIAL
FURNISHED BY SELLER IS PROVIDED AS A CONVENIENCE ONLY AND ANY RELIANCE ON OR USE
OF SAME IS AT BUYER'S SOLE RISK.

                                                                              10

                ARTICLE 7. ENVIRONMENTAL MATTERS AND ADJUSTMENTS

      7.1. Upon execution of and pursuant to the terms of this Agreement, Buyer
shall have the right, at reasonable times during normal business hours, to
conduct its investigation into the status of the physical and environmental
condition of the Assets. If, in the course of conducting such investigation,
Buyer discovers that any Asset is subject to a material Environmental Defect,
Buyer may raise such Environmental Defect in the manner set forth hereafter. For
purposes hereof, the term "material" shall mean that the cost of remediating any
single defect exceeds $100,000.00, the parties agreeing that such amount will be
a per Asset deductible rather than a threshold; in this context each separately
designated asset described on Exhibit "B" hereto will constitute a separate
"Asset". No later than 5:00 p.m., C.D.T., on November 1, 2005 (the
"Environmental Defect Notice Date"), Buyer shall notify Seller in writing
specifying such Environmental Defects, if any, the Assets affected thereby, and
Buyer's good faith estimate of the net reduction in value of the Assets affected
by such defects (the "Environmental Defect Value"). Prior to Closing, Buyer and
Seller shall treat all information regarding any environmental conditions as
confidential, whether material or not, and shall not make any contact with any
governmental authority or third party regarding same without the written consent
of the other party unless required by law.

      7.2. If Buyer fails to notify Seller prior to or on the Environmental
Defect Notice Date, of any Environmental Defects, all Environmental Defects not
timely noticed to Seller pursuant to Section 7.1 will be deemed waived, Seller
shall be released from any liability therefor, the Parties shall proceed with
Closing, Seller shall be under no obligation to correct the defects, and Buyer
shall assume the risks, liability and obligations associated with such defects.
Seller may, but shall be under no obligation to, correct at its own cost and
expense such defects on or before the Closing Date.

      7.3. In the event that Buyer provides Seller with an Environmental Defect
Notice, Seller, at its sole option, shall, (i) agree to cure or remediate any
Environmental Defect within a reasonable time after Closing as provided in
Section 7.4; or, (ii) reduce the Purchase Price by the amount of the
Environmental Defect Value; provided, however, if an Environmental Defect poses
a material risk of any claims by third parties for damages, injunctive relief or
any other remedy other than the remediation contemplated in determining the
Environmental Defect Value, or if the estimated Environmental Defect Value
exceeds 20% of the Allocated Value of the affected Asset, then Buyer shall have
the right to delete the affected Asset from the Assets to be conveyed under this
Agreement, and receive a reduction of the Purchase Price in the amount of the
Allocated Value of such Asset, in which event 100% of the Allocated Value of
such Asset shall be included in the calculation of total defects for purposes of
Article 9. Regardless of Seller's intention to cure or remediate an
Environmental Defect after Closing, the value of all Environmental Defects not
cured or remediated by Closing shall be included in the calculation of total
defects for purposes of Article 9.

      7.4 If Seller elects to proceed under Section 7.3(i) with respect to an
Environmental Defect, Seller shall remediate such Environmental Defect as soon
as reasonably practicable after Closing in accordance with applicable law, in
which case the following provisions will govern the remediation:

                                                                              11

<PAGE>

      (a) An amount equal to the Environmental Defect Value of such
Environmental Defect shall be placed in escrow by Buyer, with an escrow agent
and pursuant to an escrow agreement mutually acceptable to the Parties, and the
Purchase Price shall be reduced by such amount.

      (b) Buyer will grant access to the Assets after Closing to Seller, and
third parties conducting assessments or remediation, to the extent and as long
as necessary to conduct and complete the assessment or remediation work, to
remove equipment and facilities, and to perform any other activities reasonably
necessary in connection with assessment or remediation. Buyer will use its
commercially reasonable efforts not to interfere with Seller's ingress and
egress or assessment or remediation activities. Seller will make reasonable
efforts to perform the work so as to minimize disruption to Buyer's business
activities and to the Assets.

      (c) Seller shall retain the liability for, and shall indemnify, defend and
hold harmless Buyer from any Claims with respect to the Environmental Defect,
until such time as the remediation has been completed and accepted by Buyer, and
upon such acceptance by Buyer (which acceptance shall not be unreasonably
withheld or delayed), the amount escrowed on account of such Environmental
Defect shall be released to Seller (together with all interest earned thereon
..in the escrow account), and Seller shall have no further liability or
indemnification obligation with respect to such Environmental Defect.

      (d) Until Seller completes remediation of an Environmental Defect, Seller
and Buyer will each notify the other of any pending or threatened claim, action,
or proceeding by any authority or private party that relates to or would affect
the Environmental Defect or the remediation of the Assets affected by the
Environmental Defect.

      (e) If Seller undertakes remediation as to any Asset in which Seller's
ownership is less than 100%, Buyer will bill the other working interest owners
for their share of the remediation expenses in advance of Seller beginning such
remediation to the extent permitted under the applicable operating agreement and
will pay over to Seller any amount so received provided that Buyer shall have no
obligation to initiate any legal proceeding to collect such amounts and shall be
entitled to deduct any reasonable costs of collection from the amount received
to be paid to Seller.

      7.5 Notwithstanding anything contained herein to the contrary, there shall
be no adjustments to the Non-Producing Leasehold (as described in Exhibit B
hereto) pursuant to Articles 7 and 9 hereof.

                    ARTICLE 8. TITLE DEFECTS AND ADJUSTMENTS

      8.1. Definitions.

      For purposes hereof, the terms set forth below shall have the meanings
assigned thereto.

      (a) "Allocated Value" shall mean the dollar amount allocated to each Asset
as set forth on Exhibit B.

                                                                              12

<PAGE>

      (b) "Defensible Title", subject to and except for the Permitted
Encumbrances (as hereinafter defined), means: As to the Leases, such title held
by Seller and reflected by appropriate documentation properly filed in the
official records of the jurisdiction in which the Lease or Leases are located
that (a) entitles Seller and will entitle Buyer, after Closing, to own and
receive and retain, without suspension, reduction or termination, payment of
revenues for not less than the net revenue interest shown on Exhibit B of all
oil and gas produced, saved and marketed from or attributable to the well or
unit indicated through the plugging, abandonment and salvage of such wells; (b)
obligates Seller, and will obligate Buyer after Closing, to bear the costs and
expenses relating to the maintenance, development and operation of such well or
unit through the plugging, abandonment and salvage of such wells in an amount
not greater than the expense interest of Seller set forth in Exhibit B (unless
Seller's net revenue interest therein is proportionately increased); and (c) the
Assets are free and clear of any liens, burdens or encumbrances of any kind or
character.

      (c) "Title Defect" shall mean any matter which (i) causes Seller to have
less than Defensible Title to any of the Assets as of the Closing Date, or (ii)
causes any of the following to be untrue:

            (A) Leases. The Leases are in full force and effect, are valid and
subsisting. Except for the matters described in Schedule 8.1(c)(A), within the
last two years Seller has not been notified by any lessor under any Lease or by
any other party of a default under any Lease that has not been resolved or of
any requirements or demands to drill additional wells on any of the Leases.
Further, all contracts affecting the Assets are of the type generally found in
the oil and gas industry in the geological area in which the Assets in question
are located, do not (individually or in the aggregate) contain unusual or unduly
burdensome provisions which may operate in a materially adverse manner with
respect to the Assets or to the Buyer, and are in form and substance considered
conventional within the oil and gas industry in the geographical area in which
the Assets are located.

            (B) Material Contracts; Required Capital Expenditures. Seller is not
in default, and within the last two years has not received any written notice
from any person alleging that Seller is in default, in any material respect
under any material contract or agreement pertaining to the Assets except for
those alleged defaults described in Schedule 8.1(c).

            (C) Proration. The production from the wells has not been prorated.

            (D) Tax Partnerships. Except as set forth on the attached Schedule
8.1(c) (D), , no portion of the Assets (1) has been contributed to and is
currently owned by a tax partnership; (2) is subject to any form of agreement
(whether formal or informal, written or oral) deemed by any federal tax statute,
rule or regulation to be or to have created a tax partnership; or (3) otherwise
constitutes "partnership property" (as that term is used throughout Subchapter K
of Chapter 1 of Subtitle A of the Code) of a tax partnership. For purposes of
this Section 8.1(c)(D) a "tax partnership" is any entity, organization or group
deemed to be a partnership within the meaning of section 761 of the Code or any
similar federal statute, rule or regulation, and that is not excluded from the
application of the partnership provisions of Subchapter K of Chapter 1 of
Subtitle A of the Code by reasons of elections made, pursuant to section 761 (a)
of the Code and all such similar federal statutes, rules and regulations, to be
excluded from the application of all such partnership provisions.

                                                                              13

<PAGE>

      (d) "Title Defect Property" shall mean any Lease or portion thereof
burdened by a Title Defect.

      (e) "Permitted Encumbrances" shall mean any of the following matters:

            (i) defects in the early chain of title consisting of failure to
recite marital status or the omission of succession or heirship proceedings;

            (ii) defects or irregularities arising out of prior oil and gas
leases which, on their face, expired more than ten (10) years prior to the
Effective Time, and which have not been released of record;

            (iii) tax liens and mechanic's liens for amounts not yet due and
payable, or those that are being contested in good faith by Seller in the
ordinary course of business (which contests and contested amounts are described
in Schedule 8.1 (e)(iii) hereto);

            (iv) to the extent any of the following do not materially diminish
the value of, or impair the conduct of operations on, any of the Assets and do
not impair Seller's right to receive the revenues attributable thereto: (x)
easements, rights-of-way, servitudes, permits, surface leases and other rights
in respect of surface operations, pipelines, grazing, hunting, fishing, logging,
canals, ditches, reservoirs or the like, and (y) easements for streets, alleys,
highways, pipelines, telephone lines, power lines, railways and other similar
rights-of-way, on, over or in respect of property owned or leased by Seller or
over which Seller owns rights of way, easements, permits or licenses;

            (v) all lessors' royalties, overriding royalties, net profits
interests, carried interest, production payments, reversionary interests and
other burdens on or deductions from the proceeds of production if the net
cumulative effect of such burdens or deductions does not reduce the net revenue
interest of Seller in any well affected thereby to a percentage less than that
percentage reflected in Exhibit B or impair the right to receive revenues
attributable thereto;

            (vi) preferential rights to purchase and required third party
consents to assignments and similar agreements with respect to which waivers or
consents are obtained from the appropriate parties prior to the Closing Date, or
the appropriate time period for asserting the rights has expired without an
exercise of the rights prior to the Closing Date;

            (vii) all rights to consent by, required notices to, filings with,
or other actions by governmental entities and tribal authorities in connection
with the sale or conveyance of oil and gas leases or interests if they are
customarily obtained subsequent to the sale or conveyance;

            (viii) defects or irregularities of title arising out of events or
transactions which have been barred by limitations;

            (ix) any encumbrance or other matter (other than liens securing
indebtedness originated by or expressly assumed by Seller or its affiliates,
which shall not be subject to any deductible) having an aggregate adverse effect
on the value of the

                                                                              14

<PAGE>

Assets of less than $100,000.00, the parties agreeing that such amount will be a
per Asset deductible rather than a threshold; and

            (x) any encumbrance or other matter (whether or not constituting a
"Title Defect") expressly waived in writing by Buyer.

      8.2. Notice of Title Defects.

      No later than 5:00 p.m., C.S.T., on November 1, 2005 (the "Title Defect
Notice Date"), Buyer may provide Seller written notice of any Title Defect along
with a description of those matters which, in Buyer's reasonable opinion,
constitute Title Defects and setting forth in detail Buyer's calculation of the
value for each Defect. Seller may elect, at its sole cost and expense, but
without obligation, to cure all or any portion of such Title Defects. Buyer's
failure to deliver to Seller such notice on or before the Defect Notice Date
shall be deemed a waiver by Buyer of all Title Defects that Seller does not have
notice of on such date. Any defect or deficiency concerning Seller's title to
the Assets not asserted by Buyer prior to the Title Defect Notice Date shall be
deemed waived by Buyer for all purposes.

      8.3. Title Defect Adjustment.

      (a) Seller shall have the opportunity to cure, until sixty (60) days after
Closing ("Cure Period"), any Title Defect, or, alternatively, Seller may elect
to cure such Title Defect by indemnifying Buyer against any damages, claims or
expenses that may arise out of such Title Defect, subject to the provisions of
Section 8.3(b) below. If Seller elects to attempt to cure a Title Defect after
Closing, Closing with respect to the portion of the Assets affected by such
Title Defect will be deferred (the "Closing Deferred Property"). Closing with
respect to all other Assets will proceed as provided in this Agreement (subject
to Article 9 and the other provisions of this Agreement), but the Base Purchase
Price delivered to Seller at such initial Closing will be reduced by the
Allocated Value of all Closing Deferred Properties. If Seller cures any Title
Defect within the Cure Period, then the Closing with respect to the Closing
Deferred Property for which such Title Defect has been cured will proceed and
will be finalized within seven (7) days following the end of the Cure Period. If
Seller fails or refuses to cure any Title Defect prior to the expiration of the
Cure Period, Buyer may separately elect with respect to each affected Closing
Deferred Property, by notice to Seller delivered within seven (7) days after
receipt by Buyer of Notice from Seller of such failure or refusal to cure any
such Title Defect, to waive all of the Title Defects applicable to such Closing
Deferred Property (which waived Title Defects shall be deemed Permitted
Encumbrances) and proceed to Closing on such Closing Deferred Property. If Buyer
does not elect to waive an existing Title Defect, Seller shall retain the
affected Closing Deferred Property and the Parties shall have no further
obligation with respect thereto. In the event that any such property is retained
by Seller and such property has been receiving revenue, without complaint, for a
period in excess of two years, then Buyer agrees (i) not to take any action to
interfere with such revenue stream, and (ii) to the extent that Buyer becomes
payor of such revenue, to pay Seller such revenue upon receipt of an indemnity
agreement from Seller.

      (b) The following provisions shall apply to an election by Seller under
the first sentence of Section 8.3(a) to cure a Title Defect by indemnifying
Buyer with regard to such Title Defect, notwithstanding any other provisions of
this Agreement:

                                                                              15

<PAGE>

            (i) Seller's indemnity shall be of unlimited duration;

            (ii) Seller's indemnity shall be freely transferable by Buyer to its
successors and assigns to the Assets affected by such Title Defect, including
without limitation, any lender to Buyer and any purchaser of such Assets,
whether directly from Buyer or through any foreclosure proceeding; and

            (iii) If the Title Defect Value, individually or in the aggregate,
for one or more Title Defects to be covered by the Seller's indemnity exceeds
$500,000.00, Seller shall not have the right under the first sentence of Section
8.3(a) to indemnify Buyer with regard to such Title Defects without Buyer's
consent, and if such consent is not obtained, then either Seller or Buyer shall
have the option to terminate this Agreement as provided in Article 9 below.

      8.4. Title Defect Values.

      In determining the value of a Title Defect, it is the intent of the
Parties to include, to the extent possible, only that portion of the lands,
leases and wells, whether an undivided interest, separate interest or otherwise,
materially and adversely affected by the defect. The Title Defect value shall in
no event exceed the Allocated Value of the affected Asset. Subject to such
limitation; the "Title Defect Value" shall be determined by the parties in good
faith taking into account all relevant factors, including, but not limited to,
the following:

            (i) the Allocated Value of the leases, lands and well affected by
the Title Defect;

            (ii) the reduction in the warranted NRI of the Title Defect
Property, or the amount by which the cost sharing percentage for such property
is greater than the warranted WI;

            (iii) the productive status of the Title Defect Property (i.e.,
proved developed producing, etc.) and the present value of the future income
expected to be produced therefrom;

            (iv) if the Title Defect represents only a possibility of title
failure, the probability that such failure will occur;

            (v) the legal effect of the Title Defect; and

            (vi) if the Title Defect is a lien or encumbrance on the leases,
lands or wells, the cost of removing such lien or encumbrance.

      Notwithstanding anything to the contrary that may be contained in this
Article VIII, (i) Buyer understands and agrees that the Allocated Values set
forth in Exhibit B are for currently producing zones and that any loss of depth
rights or acreage will not have a Title Defect Value unless such loss causes a
decrease in expense or net revenue interest in the currently producing zone; and
(ii) notwithstanding anything contained herein to the contrary, there shall be
no adjustments to the Non-Producing Leasehold (as described in Exhibit B hereto)
pursuant to Articles 7 and 9 hereof.

                                                                              16

<PAGE>

      8.5. Title Warranty.

      SELLER SHALL CONVEY SELLER'S INTERESTS IN AND TO THE ASSETS TO BUYER
SUBJECT TO ALL ROYALTIES, OVERRIDING ROYALTIES, BURDENS, AND ENCUMBRANCES,
WITHOUT WARRANTY OF TITLE, AS PROVIDED IN THE FORM OF ASSIGNMENT, BILL OF SALE
AND CONVEYANCE ATTACHED AS EXHIBIT C HERETO EXCEPT THAT SELLER SHALL WARRANT
TITLE TO THE ASSETS AGAINST ALL CLAIMS, LIENS, BURDENS AND ENCUMBRANCES ARISING
BY, THROUGH OR UNDER SELLER, BUT NOT OTHERWISE. IMBALANCES WITH RESPECT TO OIL
OR NATURAL GAS ARE GOVERNED BY ARTICLE 18 HEREOF. THE PARTIES AGREE THAT THE
EXISTENCE OF ANY SUCH IMBALANCES SHALL NOT BE DEEMED A TITLE DEFECT.

                         ARTICLE 9. OPTION TO TERMINATE

      If the aggregate of the values attributable to all Title Defects
determined pursuant to Article 8 plus the value of all Environmental Defects
determined pursuant to Article 7 plus the aggregate value of a reduction to the
Purchase Price pursuant to Article 10 exceeds Four Million Eight Hundred Fifty
Thousand and no/100 Dollars ($4,850,000.00), then either Buyer or Seller may, at
its sole option, terminate this Agreement without any further obligation by
giving written notice of termination. In the event of such termination, Seller
shall return the Performance Deposit to Buyer, without interest, within five (5)
days of receipt of the notice of termination and neither party shall have any
further obligation or liability hereunder.

              ARTICLE 10. PREFERENTIAL PURCHASE RIGHTS AND CONSENTS

      10.1. Actions and Consents.

      (a) Seller and Buyer agree that each shall use all reasonable efforts to
take or cause to be taken all such action as may be necessary to consummate and
make effective the transaction provided in this Agreement and to assure that it
will not be under any material corporate, legal, or contractual restriction that
could prohibit or delay the timely consummation of such transaction.

      (b) Seller shall notify all holders of (i) preferential rights to purchase
the Assets ("Preferential Purchase Rights"), (ii) rights of consent to the
assignment, or (iii) rights of approval to the assignment of the Assets, and of
such terms and conditions of this Agreement to which the holders of such rights
are entitled. Seller shall promptly notify Buyer if any Preferential Purchase
Rights are exercised, any consents or approvals denied, or if the requisite
period has elapsed without said rights having been exercised or consents or
approvals having been received. If prior to Closing, any such Preferential
Purchase Rights are timely and properly exercised, or Seller is unable to obtain
a necessary consent or approval prior to Closing, the interest or part thereof
so affected shall be eliminated from the Assets and the Purchase Price reduced
by the portion of the Purchase Price allocated to such interest or part thereof
as provided in Exhibit B. If any additional Preferential Purchase Rights are
discovered after Closing, or if a third party Preferential Purchase Rights
holder alleges improper notice, then Buyer agrees to cooperate with Seller in
giving effect to any such valid third party Preferential Purchase Rights. In the
event any such valid third party preferential purchase rights are validly
exercised after Closing, Buyer's sole remedy against Seller shall be return by
Seller to Buyer of that portion of the Purchase Price

                                                                              17

<PAGE>

allocated under Exhibit B to the portion of the assets on which such rights are
exercised and lost by Buyer to such third party. The parties agree that the
Allocated Values for properties subject to Preferential Purchase Rights shall be
the sole responsibility of Buyer, and Buyer agrees to indemnify and hold Seller
harmless from all liability and claims related to the reasonableness of such
values.

      (c) With respect to any portion of the Assets for which a Preferential
Purchase Right has not been asserted prior to Closing or a consent or other
approval to assign has not been granted and for which the time for election to
exercise such Preferential Purchase Right or to grant such consent has not
expired, Closing with respect to the portion of the Assets subject to such
outstanding obligations will be deferred (the "Third Party Interests"). Closing
with respect to all other Assets will proceed as provided in this Agreement, but
the Base Purchase Price delivered to Seller at Closing will be reduced by the
allocated value of the Third Party Interests. In the event that within ninety
(90) days after Closing any such Preferential Purchase Right is waived or
consent or approval is obtained or the time for election to purchase or to
deliver a consent or approval passes (such that under the applicable documents,
Seller may sell the affected Third Party Interest to Buyer), then the Closing
with respect to the applicable portion of the Third Party Interests will proceed
promptly. If such waivers, consents or approvals as are necessary are not
received by Seller within the applicable ninety (90) day period, Seller shall
retain such Third Party Interests and the parties shall have no further
obligation to each other with respect thereto.

                         ARTICLE 11. COVENANTS OF SELLER

      11.1. Covenants of Seller Pending Closing.

      (a) From and after the date of execution of this Agreement and until the
Closing, and subject to Section 11.2 and the constraints of applicable operating
and other agreements, Seller shall operate, manage, and administer the Assets in
a good and workmanlike manner consistent with its past practices, and shall
carry on its business with respect to the Assets in substantially the same
manner as before execution of this Agreement. Seller shall use all reasonable
efforts to preserve in full force and effect all Leases, operating agreements,
easements, rights-of-way, permits, licenses, and agreements which relate to the
Assets in which Seller owns an interest, and shall perform all obligations of
Seller in or under all such agreements relating to the Assets; provided,
however, Buyer's sole remedy for Seller's breach of its obligations under this
Section 10.1(a) shall be limited to the amount of that portion of the Purchase
Price allocated in Exhibit B to that portion of the Assets affected by such
breach. Seller shall, except for emergency action taken in the face of serious
risk to life, property, or the environment (1) submit to Buyer, for prior
written approval, all requests for operating or capital expenditures and all
proposed contracts and agreements relating to the Assets which involve
individual commitments of more than $25,000.00; (2) consult with, inform, and
advise Buyer regarding all material matters concerning the operation,
management, and administration of the Assets; (3) obtain Buyer's written
approval prior to voting under any operating, unit, joint venture, partnership
or similar agreement; and (4) not approve or elect to go nonconsent as to any
proposed well or plug and abandon or agree to plug and abandon any well without
Buyer's prior written approval. On any matter requiring Buyer's approval under
this Section 10.1(a), Buyer shall respond within five (5) days to Seller's
request for approval and failure of Buyer to respond to Seller's request for
approval within such time shall

                                                                              18
<PAGE>

release Seller from the obligation to obtain Buyer's approval before proceeding
on such matter.

      (b) Seller shall promptly notify Buyer of any suit, lessor demand action,
or other proceeding before any court, arbitrator, or governmental agency and any
cause of action which relates to the Assets or which might result in impairment
or loss of Seller's interest in any portion of the Assets or which might hinder
or impede the operation of the Assets.

      11.2. Limitations on Seller's Covenants Pending Closing.

      To the extent Seller is not the operator of any of the Assets, the
obligations of Seller in Section 11.1 concerning operations or activities which
normally or pursuant to existing contracts are carried out or performed by the
operator, shall be construed to require only that Seller use all reasonable
efforts (without being obligated to incur any expense or institute any cause of
action) to cause the operator of such Assets to take such actions or render such
performance within the constraints of the applicable operating agreements and
other applicable agreements.

                         ARTICLE 12. CLOSING CONDITIONS

                   ARTICLE 15. CASUALTY LOSS AND CONDEMNATION

      If, prior to the Closing, all or any portion of the Assets is destroyed by

Assets which is subject to the Casualty Loss from the Assets, and the Purchase
Price shall be reduced by the value allocated to the deleted interest as set out
in Exhibit B, or (ii) for Buyer to proceed with the purchase of such Assets,
notwithstanding any such destruction or taking (without reduction of the
Purchase Price) in which case Seller shall pay, at the Closing, to Buyer all

other than Section 6.3 shall be to retain the Performance Deposit as a
liquidated damage and not as a penalty, and terminate this Agreement, all other
remedies being expressly waived by Seller. Notwithstanding any provision hereof
to the contrary Seller may retain the Deposit as a liquidated damage only in the

the breach hereof by Buyer in the absence of any material breach hereof by
Seller. If the transaction contemplated by this Agreement fails to close or is
terminated for any other reason, the Performance Deposit shall be returned to
Buyer.

                                                                              22

terminate this Agreement as set forth above, Seller shall immediately return the
Performance Deposit to Buyer.

      16.3. Other Remedies.

      Notwithstanding the foregoing, termination of this Agreement shall not
prejudice or impair Buyer's obligations under Section 6.3 (and the
confidentiality agreements referenced therein). The prevailing party in any
legal proceeding brought under or to enforce this Agreement shall be
additionally entitled to recover court costs and reasonable attorneys' fees from
the non-prevailing party.

      16.4. Effect of Termination.

In the event of termination of this Agreement under this Article 16, the
transaction shall not close and neither Buyer nor Seller shall have any further

      17.4. Negligence.

      Seller and Buyer will use their best efforts to update (to the Effective
Time) the gas imbalance volume amounts listed on Exhibit F. If, prior to the
Final Settlement Date, either party hereto notifies the other party hereto that
the volumes set forth in Exhibit F are incorrect, then Buyer or Seller will pay
the other at the Final Settlement, as appropriate, an amount equal to $10.00 per
net mmbtu variance from the net imbalance shown on Exhibit F. Subject to such
adjustment on the Final Settlement Date, as of the Closing Buyer agrees to
assume any liability and obligation for gas production imbalances (whether over
or under) attributable to the Assets. Except as set forth in this Article 18, in
assuming this liability at Closing, Buyer shall not be obligated to make any
additional payment over the Purchase Price to Seller, and Seller shall not be
obligated to refund any of said price to reimburse Buyer for any over-balances
existing at the time of sale.

      (d) To the extent not obtained or satisfied as of Closing, Seller agrees
to continue to use all reasonable efforts, but without any obligation to incur
any cost or expense in connection therewith, and to cooperate with Buyer's

costs and expenses.

      19.6. Waiver.

      Any of the terms, provisions, covenants, representations, warranties or
conditions hereof may be waived only by a written instrument executed by the
party waiving compliance. Except as otherwise expressly provided in this
Agreement, the failure of any party at any time or times to require performance

The rights of each party under this Agreement are personal to that party and may
not be assigned or transferred to any other party, firm, corporation or other
entity, without the prior, express and written consent of the other party, and
such consent may be withheld for any reason, including convenience. Any attempt
to assign this Agreement over the objection or without the express written
consent of the other party shall be absolutely void. Seller may condition its
consent to assign this Agreement on Buyer providing Seller with an appropriate
guarantee of its assignee's performance. In the event Buyer sells or assigns all
or a portion of the Assets, this Agreement shall remain in effect between Buyer
and Seller as to all the Assets regardless of such assignment.

      19.8. Taxes.

      (a) Seller and Buyer agree that this transaction is not subject to the
reporting requirement of Section 1060 of the Internal Revenue Code of 1986, as
amended, and that, therefore, IRS Form 8594, Asset Acquisition Statement, is not
required to be and will not be filed for this transaction. In the event the
parties mutually agree that a filing of Form 8594 is required, the parties will
confer and cooperate in the preparation and filing of their respective forms to
reflect a consistent reporting of the agreed upon allocation.

      (b) Seller shall be responsible for and shall pay all taxes attributable
to or arising from the ownership or operation of the Assets prior to the
Effective Time.

                                                                              27

<PAGE>

Buyer shall be responsible for and shall pay all taxes attributable to or
arising from the ownership or operation of the Assets after the Effective Time.
Any party which pays such taxes for the other party shall be entitled to prompt
reimbursement upon evidence of such payment.

      Each party shall be responsible for its own federal income taxes, if any,
as may result from this transaction.

      (c) If this transaction is determined to result in state sales or transfer
taxes, Buyer shall be solely responsible for any and all such taxes due on the
Assets acquired by Buyer by virtue of this transaction. If Buyer is assessed
such taxes, Buyer shall promptly remit same to the taxing authority. If Seller
is assessed such taxes, Buyer shall reimburse Seller for any such taxes paid by
Seller to the taxing authority.

      19.9. Confidentiality of Agreement.

      This Agreement and the terms and provisions thereof, including the
Purchase Price, shall be maintained confidential by Buyer and Seller until
Closing; provided, however, that this Agreement and the terms and provisions
thereof may be disclosed to Buyer's lenders, if any, and their consultants, who
shall be required to keep such information confidential.

      19.10. Audits.

      It is expressly understood and agreed that Seller retains its right to
receive its proportionate share of the proceeds from any audits relating to
activities prior to the Effective Time, except to the extent such proceeds are
directly related to the Assumed Obligations. However, Buyer shall have the right
to audit the books and records of Seller in order to fulfill any and all SEC and
other governmental requirements to which Buyer is subject.

      19.11. Like-Kind Exchanges.

      Each party consents to the other party's assignment of its rights and
obligations under this Agreement to its Qualified Intermediary (as that term is
defined in Section 1. 1031 (k)-I(g)(4)(v) of the Treasury Regulations) in
connection with effectuation of a like-kind exchange. However, Seller and Buyer
acknowledge and agree that any assignment of this Agreement to a Qualified
Intermediary does not release either party from any of their respective
liabilities and obligations to each other under this Agreement. Each party
agrees to cooperate with the other to attempt to structure the transaction as a
like-kind exchange.

      19.12. Governing Law.

      THIS AGREEMENT SHALL BE GOVERNED, CONSTRUED AND ENFORCED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS
OF LAWS OTHERWISE APPLICABLE TO SUCH DETERMINATIONS.

related to the subject matter hereof, whether written or oral. No other
agreement, statement, or promise made by any party, or to any employee, officer
or agent of any party, which is not contained in this Agreement shall be binding

      The Assets set out in Section 1.14(d) shall be provided by Seller to Buyer
as soon as reasonably possible after the Closing Date at a location to be
specified by Seller. Any transportation, postage, or delivery costs from
Seller's offices shall be at Buyer's sole cost, risk and expense.

      19.16. Survival.

      All of the representations, warranties, indemnities, covenants and
agreements of or by the parties hereto shall survive the execution and delivery
of the Assignment and Conveyance indefinitely.

      19.17. Subsequent Adjustments.

      Regardless of the date set for the Final Settlement, Buyer and Seller
agree that their intent is to allow for the earliest practical forwarding of
revenue and reimbursement of expenses between them, and Seller and Buyer
recognize that either may receive funds or pay expenses after the Final
Settlement Date which are properly the property or obligation of the other.
Therefore, upon receipt of net proceeds or payment of net expenses due to or
payable by the other party hereto, whichever occurs first, Seller or Buyer, as
the case may be, shall submit a statement to the other party hereto showing the
relevant items of income and expense. Payment of any net amount due by Seller or
Buyer, as the case may be, on the basis thereof shall be made within ten days of
receipt of the statement.

                                                                              29

This release contains forward-looking statements subject to various risks and
uncertainties that could cause the company's future plans, objectives and
performance to differ materially from those in the forward-looking statements.
Forward-looking statements can be identified by the use of forward-looking
