         1.3.3 PURCHASE PRICE ADJUSTMENT CERTIFICATE. As soon as reasonably
practicable, and in any event within sixty (60) days following the Closing Date,
Seller shall deliver to Purchaser the Purchase Price Adjustment Certificate.
Within thirty (30) days after delivery of the Purchase Price Adjustment
Certificate, Purchaser shall notify Seller on behalf of Seller, whether
Purchaser agrees or disagrees with the determination of the Purchase Price
Adjustment Amount set forth in the Purchase Price Adjustment Certificate. If
Purchaser disagrees with such determination, representatives of Purchaser and
Seller shall meet and endeavor to resolve their differences regarding the
determination of the Purchase Price Adjustment Amount. If the representatives of
Purchaser and Seller are unable to agree upon such determination of the Purchase
Price Adjustment Amount within twenty (20) business days after Purchaser's
receipt of such notification, Seller shall select an independent accounting firm
from a list of three (3) such firms provided by Purchaser, which firm shall
audit the Purchase Price Adjustment Certificate and determine the Purchase Price
Adjustment Amount. The decision of such independent accounting firm shall be
binding on Seller and Purchaser, and the fees and expenses of such independent
accounting firm shall be borne one-half by Seller and one-half by Purchaser.

         1.3.4 PAYMENT OF PURCHASE PRICE ADJUSTMENT AMOUNT. If the Purchase
Price Adjustment Amount as finally determined pursuant to Section 1.3.3 is a
smaller upward adjustment or a larger downward adjustment than that estimated
pursuant to Section 1.3.2, Seller shall pay to Purchaser the amount of such
excess plus interest thereon at the Agreed Interest Rate from (and including)
the Closing Date to (but excluding) the date of payment. If the Purchase Price
Adjustment Amount as finally determined pursuant to Section 1.3.3 is a larger
upward adjustment or a smaller downward adjustment than that estimated pursuant
to Section 1.3.2, Purchaser shall pay to Seller the amount of such deficiency
plus interest thereon at the Agreed Interest Rate from (and including) the
Closing Date to (but excluding) the date of payment. Any payments contemplated
by this Section 1.3.4 shall be made by wire transfer in federal or other
immediately available funds on or before the fifth business day following the
final determination of the amount thereof.

         1.4 RETAINED RIGHTS AND CLAIMS. Notwithstanding any provision herein to
the contrary, Transferred Assets shall not include any rights or claims of

   10

                  (iv) there has not occurred any event, fact or circumstance
         which with the lapse of time or the giving of notice, or both, would

                  expiration of the Environmental Indemnity Period shall be
                  extended as to any bona fide claim with respect to the breach
                  of such representation or warranty, solely to the extent that
                  Purchaser asserted such claim according to the procedures
                  provided in Section 10.5 and Section 10.6, if the Purchaser
                  shall have transmitted the Claim Notice with respect to such
                  claim to the Seller prior to the expiration of such
                  Environmental Indemnity Period.

Article III, in any schedule or exhibit to this Agreement, or in any certificate
or document furnished or to be furnished by Seller on the Closing Date, contains

                           INSPECTION OF TITLE MATTERS

         6.1      TITLE DEFECTS.

                  (a) Any Encumbrances that individually or in the aggregate
         with other defects could cause the title of Seller in any Property
         described in Exhibit A to be less than Defensible Title shall be a
         title defect ("Title Defect"). Purchaser shall be entitled to the
         remedies set forth in Section 6.3 for any matter that constitutes a
         Title Defect even though Purchaser could but for this provision, after
         Closing obtain indemnification for such matter pursuant to Section
         10.2.

                  (b) Any circumstances or condition that could operate to cause
         (i) the Net Revenue Interest of Seller to increase above that set forth
         on Exhibit A without an increase in the Working Interest of Seller, or
         (ii) the Working Interest of Seller to decrease below that set forth on
         Exhibit A without a decrease in the Net Revenue Interest of Seller,
         shall be a title benefit ("Title Benefit").

         6.2 NOTICE OF TITLE DEFECTS AND TITLE BENEFITS.

                  (a) From time to time during the period from the date of
         execution of this Agreement until seven (7) days prior to the Closing
         Date (the "Title Examination Period"), Purchaser shall have the right
         (but not the obligation) to notify Seller of any Title Defect of which
         Purchaser becomes aware, providing in such notice a reasonably detailed
         description of such Title Defect. If the Closing Date is extended
         beyond the Closing Date stated herein in accordance with the provisions
         hereof, then the Title Examination Period shall be extended for a
         similar and parallel length of time. With respect to each notice of a
         Title Defect given during such period, Seller may, but shall have no
         obligation to, attempt to cure such Title Defect prior to Closing.
         Purchaser's failure to give notice of a Title Defect shall not impair
         Purchaser's rights under any express warranty or indemnification made
         by Seller under this Agreement or the Instruments of Transfer.

                  (b) From time to time during the Title Examination Period,
         Purchaser shall notify Seller of any Title Benefits of which Purchaser
         becomes aware and Seller shall have the right (but not the obligation)
         to notify Purchaser of any Title Benefit of which they become aware.
         The value of any such Title Benefits shall be mutually agreed upon by
         Purchaser and Seller, taking into consideration the allocated value of
         the Property (as set forth on allocation of the Purchase Price) subject
         to the Title Benefit, the portion of the Property subject to the Title
         Benefit, the legal effect of the Title Benefit and the anticipated
         economic effect of the Title Benefit over the life of the Property
         subject to such Title Benefit.

         6.3 REMEDIES FOR TITLE DEFECTS. In the event that any Title Defects is
not cured on or before Closing, Purchaser may. at its own election, (a) waive
such Title Defect, (b) elect to terminate this Agreement pursuant to Section
9.1, or (c) reduce the Purchase Price by an amount mutually agreed upon by
Purchaser and Seller as being the value of such Title Defect, taking into
consideration the allocated value of the Property subject to the Title Defect,
the portion of the Property subject to the Title Defect, the legal effect of the
Title Defect on the Property and the liability of Purchaser relative to the
allocated liabilities related to the Property and/or whether the Title Defect is
applicable to a portion of the Property that is not encumbered by the allocated
liability, and the anticipated economic effect of the Title Defect 


                                       15
   17

over the life of the Property subject to the Title Defect (including the
potential amount of reduction of discounted present net worth of net future cash
flow on account of such Title Defect), subject to offset for the value of Title
Benefits. If the parties are unable to agree as to the amount of any adjustment
under Section 6.3 (c), either party may terminate this Agreement.
Notwithstanding anything to the contrary in this Section 6.3, in no event shall
the reduction in the Purchase Price for all Title Defects affecting any Property
exceed the allocated value of such Property.

         6.4 SELLER'S WARRANTY OF TITLE. The Conveyances shall contain a special
warranty of title whereby Seller binds and obligates itself, its successors and
assigns, to warrant and forever defend unto Purchaser, its successors and
assigns, title to the Properties and other tangible Transferred Assets against

it has had full access to the records of Seller and the information contained
in, or made available or provided with respect to materials contained in, the
records of Seller, and that Purchaser has made its own independent
investigation, analysis and evaluation of the Transferred Assets, (including its
own estimate and appraisal of the extent and value of Seller's Hydrocarbon
reserves). Notwithstanding the foregoing, to the Knowledge of Seller, the
information contained in the records of Seller and information otherwise made
available or furnished in writing to Purchaser by Seller with respect to the
Transferred Assets does not contain any untrue 


                                       20
   22

statement of a material fact or omit to state any material fact that would make
such information not false or misleading.

fulfill and discharge all costs, expenses and liabilities incurred in connection
with the Transferred Assets prior to the Closing Date with respect to the

all claims, losses, damages, costs, expenses, causes of action and judgments of
any kind or character with respect to all liabilities, including the Retained
Liabilities, arising out of or in connection with the ownership or operation of
the Transferred Assets prior to the Closing Date, including, without limitation,
any interest, penalty and other costs and expenses incurred in connection
therewith or the defense thereof (provided that any loss, damage or expense
sustained by Purchaser arising out of or resulting from any breach or violation
of Section 3.10 shall be governed by Section 10.4); provided, however, that
Purchaser shall not be entitled to assert rights of indemnification under this
Section 10.2 or Section 10.4 unless and until the aggregate of all such losses
exceeds $25,000 (it being understood that such losses shall accumulate until
such time or times as the aggregate of all such losses exceeds $25,000,
whereupon Purchaser shall be entitled to indemnification under this Section 10.2
or Section 10.4 for any such losses); and provided, further, that the maximum
aggregate of all losses for which Purchaser shall be entitled to indemnification
by any Seller, whether under this Section 10.2, Section 10.4 or otherwise, shall
not exceed such Seller's share of the Purchase Price.

         10.3 INDEMNIFICATION OF SELLER. Purchaser agrees (i) to indemnify
Seller against, and hold Seller harmless from, any loss, damage or expense
(including reasonable attorneys' fees) sustained by Seller arising out of or

character with respect to all liabilities to third parties arising out of or in
connection with the ownership or operation of the Transferred Assets from and
after the Closing Date, including, without limitation, any interest, penalty and
other costs and expenses incurred in connection therewith or the defense thereof
(provided that any loss, damage or expense sustained by Seller arising out of or
resulting from any breach or violation of Article VIII shall be governed by
those provisions); provided. however, that Seller shall not be entitled to
assert rights of indemnification under this Section 10.3 unless and until the
aggregate of all such losses exceeds $25,000 (it being understood that such
losses shall accumulate until such time or times as the aggregate of all such
losses exceeds $25,000, whereupon Seller shall be entitled to indemnification
under this Section 10.3 for any such losses).

         10.4     ENVIRONMENTAL INDEMNITY.

                  (a) Subject to the financial limitations regarding the
         indemnity of Seller described in Section 10.2, Seller agrees, during
         the Environmental Indemnity Period, to indemnify and save Purchaser
         harmless from and against, and to reimburse Purchaser with respect to,
         any and all claims, demands, losses, damages, liabilities, causes of
         action, judgments, penalties, costs and 


                                       21
   23

         expenses (including, without limitation, reasonable legal fees and
         expenses, clean-up costs and disbursements) accrued or incurred by
         Purchaser at any time and from time to time, during the Environmental
         Indemnity Period by reason of (i) the breach of any representation or
         warranty of Seller as set forth in Section 3.10, (ii) any violation
         with respect to or affecting the Transferred Assets on or before the
         Closing Date of any Environmental Laws in effect on or before the
         Closing Date, (iii) the clean-up of the Transferred Assets required
         under Environmental Laws for any activities prior to the Closing Date,
         (iv) any act, omission, event or circumstance existing or occurring on
         or prior to the Closing Date (including without limitation, the
         presence on the Properties of Hazardous Substances or the presence off
         site of Hazardous Substances generated on the Properties, on or prior
         to the Closing Date) that result from or that are in connection with
         the ownership, construction, occupancy, operation, use and/or
         maintenance of the Properties, regardless of whether the act, omission,
         event or circumstance constituted a violation of any Environmental Laws
         at the time of its existence or occurrence, and (v) any and all claims
         or proceedings (whether brought by private party or Governmental
         Authority) for bodily injury, property damage, abatement or
         remediation, environmental damage or impairment or any other injury or
         damage resulting from or relating to any Hazardous Substances located
         upon the Properties prior to the Closing Date. Seller shall also
         indemnify and hold Purchaser harmless from and against any liability,
         loss, cost or expense, including reasonable attorneys' fees and
         expenses, arising from or relating to the imposition or recording of a
         lien on the Properties in connection with any contamination of the
         Properties or pursuant to any Environmental Laws in the event only that
         such contamination occurred prior to the Closing Date. Seller shall
         also hold harmless, and indemnify Purchaser from any liability incurred
         by Purchaser arising out of regulatory action or third-party, claims
         with respect to contamination of the Properties or offsite locations
         that occurred prior to the Closing Date.

                  (b) Notwithstanding anything contained in this Agreement to
         the contrary, the indemnities in this Section 10.4 shall survive the
         Closing Date only until the end of the Environmental Indemnity Period,
         and shall be limited in scope only to any activities discovered after
         the Closing Date but before the end of the Environmental Indemnity
         Period that occurred before the Closing Date. For all purposes with
         respect to the Transferred Assets, Purchaser agrees that it shall have
         the burden of proof that any alleged activities, violations, events or
         conditions occurred before the Closing Date.

                  (c) Seller shall have the right to control any action for
         which indemnity is required under this Section 10.4 through counsel of
         its choice, subject to Purchaser's consent, which shall not be
         unreasonably withheld or delayed, provided, however, at Purchaser's
         option, Purchaser may participate in such action and appoint its own
         counsel. If Seller does not notify Purchaser in writing of its intent
         to control such action within thirty (30) days (or five (5) days less
         than such lesser time as may be required to respond to such claims)
         after receipt by Seller of written notice of such claims, Purchaser
         shall have the right to undertake the control, conduct or settlement of
         such claims through its own counsel at Seller's expense and may settle
         such matter without Seller's consent at its sole expense. In the event
         any proposed settlement includes non-monetary relief, including
         clean-up, Purchaser may agree to such clean-up and settle such matter
         only with the consent of Seller, which consent shall not be
         unreasonably withheld or delayed; provided, however, if Seller fails to
         respond to such a notification by Purchaser regarding such non-monetary
         relief within ten (10) days after Purchaser's notification to Seller,
         Seller shall be deemed to have consented to such non-monetary relief.

   24


                  (d) Purchaser agrees that the rights and remedies provided in
         this Section 10.4 shall be the exclusive rights and remedies available
         to it for any matter within the scope of Section 10.4 and that the
         general indemnification provisions of Section 10.2 and any other rights
         or remedies of Purchaser with respect to the Seller for any matter
         within the scope of Section 10.4, whether provided in this Agreement,
         at law or in equity, shall not be applicable and are hereby waived.
         Nothing in this Section 10.4 or elsewhere in this Agreement shall limit
         or impair any rights or remedies of Purchaser against any third party
         under any Environmental Laws, including, without limitation, any rights
         of contribution or indemnification available hereunder.

                  (e) Any indemnification provided in this Section 10.4 shall
         terminate at the end of the Environmental Indemnity Period, following
         which the Purchaser agrees not to institute any action or claim for
         indemnification or other recovery with respect to the matter within the
         scope of Section 10.4; provided, however, that the expiration of the
         Environmental Indemnity Period shall be extended as to any bona fide
         claim for indemnification within the scope or Section 10.4, solely to
         the extent that Purchaser asserted such claim according to the
         procedures provided in Section 10.5 and Section 10.6, if the Purchaser
         shall have transmitted the Claim Notice with respect to such claim to
         the Seller prior to the expiration of such Environmental Indemnity
         Period.

         10.5 SURVIVAL. The representations and warranties set forth in this
Agreement (other than those set forth in Article VIII) shall survive until the
second anniversary of the Closing Date, following which date none of the parties
may bring any action or present any claim for a breach of such representations
and warranties; provided, however, that there shall be no termination of any
representation or warranty as to which a bona fide claim has been asserted if
the Indemnified Party shall have transmitted the Claim Notice with respect
thereto prior to the anniversary of the Closing Date. The representations and
warranties set forth in 3.8.2 shall remain terminate in accordance with the
terms of Article VIII shall terminate in accordance with the terms of Article
VIII.

         10.6 INDEMNIFICATION PROCEDURES. All claims for indemnification under
this Agreement (other than claims for indemnification under Article VIII) shall
be asserted and resolved as follows:

         10.6.1 NOTICE. An Indemnified Party shall promptly (i) notify an
Indemnifying Party of any Third-Party Claim asserted against the Indemnified
Party and (ii) transmit to the Indemnifying Party a Claim Notice relating to
such Third-Party Claim, a copy of all papers served with respect to such claim
(if any), an estimate of the amount of damages attributable to the Third-Party
Claim and the basis of the Indemnified Party's request for indemnification under
this Agreement. During the Election Period, an Indemnifying Party shall notify
an Indemnified Party (a) whether the Indemnifying Party disputes its potential
liability to the Indemnified Party under this Article X with respect to such
Third-Party Claim and (b) whether an Indemnifying Party desires, at the sole
cost and expense of such Indemnifying Party, to defend the Indemnified Party
against such Third-Party Claim.

         10.6.2 DEFENSE BY INDEMNIFYING PARTY. If an Indemnifying Party notifies
an Indemnified Party within the Election Period that the Indemnifying Party does
not dispute its potential liability to the Indemnified Party under this Article
X and that the Indemnifying Party elects to assume the defense of the
Third-Party Claim, then the Indemnifying Party shall have the right to defend,
at its sole cost and expense, such Third-Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 10.6.2. The Indemnifying
Party shall have full control of such 



                                       23
   25

defense and proceedings, including any compromise or settlement thereof;
provided, however, that any settlement entailing non-monetary consideration must
be approved, in advance, by the Indemnified Party, which approval shall not be
unreasonably delayed or withheld. The Indemnified Party is hereby authorized, at
the sole cost and expense of the Indemnifying Party (but only if the Indemnified
Party is actually entitled to indemnification hereunder or if the Indemnifying
Party assumes the defense with respect to the Third-Party Claim), to file,
during the Election Period, any motion, answer or other pleadings which the
Indemnified Party shall deem necessary or appropriate to protect its interests
or those of the Indemnifying Party and not prejudicial to the Indemnifying Party
(it being understood and agreed that if an Indemnified Party takes any such
action that is prejudicial and conclusively causes a final adjudication adverse
to the Indemnifying Party, the Indemnifying Party shall be relieved of its
obligations hereunder with respect to such Third-Party Claim). If requested by
the Indemnifying Party, the Indemnified Party agrees, at the sole cost and
expense of the Indemnifying Party, to cooperate with the Indemnifying Party and
its counsel in contesting any Third-Party Claim that the Indemnifying Party
elects to contest, including, without limitation, the making of any related
counterclaim against the person asserting the Third-Party Claim or any
cross-complaint against any person. The Indemnified Party may participate in,
but not control, any defense or settlement of any Third-Party Claim controlled
by the Indemnifying Party pursuant to this Section 10.6, and shall bear its own
costs and expenses with respect to any such participation.

         10.6.3 DEFENSE BY INDEMNIFIED PARTY. If an Indemnifying Party fails to
notify an Indemnified Party within the Election Period that the Indemnifying
Party elects to defend the Indemnified Party pursuant to Section 10.6.2, or if
the Indemnifying Party elects to defend the Indemnified Party pursuant to
Section 10.2 but fails diligently and promptly to prosecute or settle the
Third-Party Claim, then the Indemnified Party shall have the right to defend, at
the sole cost and expense of the Indemnifying Party, the Third-Party Claim by
all appropriate proceedings, which proceedings shall be diligently prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings; and provided, however,
that without the Indemnifying Party's consent, which consent shall not be
unreasonably delayed or withheld, the Indemnified Party shall not be authorized
by the Indemnifying Party to enter into any compromise or settlement of such
Third Party Claim on any non-monetary basis; and provided further, however, that
if requested by the Indemnified Party, the Indemnifying Party shall, at the sole
cost and expense of the Indemnifying Party, cooperate with the Indemnified Party
and its counsel in contesting any Third-Party Claim that the Indemnified Party
is contesting, or, if appropriate and related to the Third-Party Claim in
question, in making any counterclaim against the person asserting the
Third-Party Claim or any cross-complaint against any person. Notwithstanding the
foregoing, if the Indemnifying Party has delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Party disputes its
potential liability to the Indemnified Party under this Article X and if such
dispute is resolved in favor of the Indemnifying Party by a final, nonappealable
order of a court of competent jurisdiction, the Indemnifying Party shall not be
required to bear the costs and expenses of the Indemnified Party's defense
pursuant to this Section 10.6 or of the Indemnifying Party's participation
therein at the Indemnified Party's request, and the Indemnified Party shall
reimburse the Indemnifying Party in full for all costs and expenses of such
litigation. The Indemnifying Party may participate in, but not control, any
defense or settlement controlled by the Indemnified Party pursuant to this
Section 10.6, and the Indemnifying Party shall bear its own costs and expenses
with respect to any such participation.

         10.6.4 OTHER CLAIMS. In the event any Indemnified Party should have a
claim against any Indemnifying Party hereunder that does not involve a
Third-Party Claim, the Indemnified Party shall transmit to the Indemnifying
Party an Indemnity Notice with respect to such claim. If the Indemnifying 


                                       24
   26

Party does not notify the Indemnified Party in writing within sixty (60) days
from its receipt of the Indemnity Notice that the Indemnifying Party disputes
such claim, the claim specified by the Indemnified Party in the Indemnity Notice
shall be deemed a liability of the Indemnifying Party hereunder. If the
Indemnifying Party has timely disputed such claim, as provided above, such
dispute shall be resolved by binding arbitration.

         10.7 TAX BENEFITS, INSURANCE PROCEEDS AND INDEMNIFICATION PAYMENTS. In
determining the amount of any loss, liability or expense for which an
Indemnified Party is entitled to indemnification under this Article X, the gross
amount thereof will be reduced by any correlative insurance proceeds, if any,
realized or to be realized by such Indemnified Party, and such correlative
insurance benefit shall be net of any insurance premium that becomes due as a
result of such claim.

         10.8 TAX ON INDEMNIFICATION PAYMENTS. After taking into account any
adjustment required by Section 10.6, the amount of each payment by an
Indemnifying Party under Section 10.2 and Section 10.3 shall include any
additional amount necessary to indemnify the Indemnified Party against any taxes
imposed in connection with such payment.

                                   ARTICLE XI
                                     BROKERS

or indirectly, employed any broker, finder or intermediary in connection with
such transactions that might be entitled to a fee or commission for which the
other party shall have any obligation or responsibility upon the execution of
this Agreement or the consummation of such transactions.

the terms of the agreement between the parties with respect to the transactions
contemplated herein.

         13.2.2 CHOICE OF LAW; CHOICE OF FORUM; AMENDMENTS; HEADINGS. This
Agreement shall be governed by the internal laws of the State of Texas, without
giving effect to principles of conflicts of laws. This Agreement may not be
changed or terminated orally. The headings contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. Terms such as "herein," "hereby," "hereto" and
