royalties, division orders, reversionary interests, and similar burdens.

set forth in Section 6.2 or in the Assignment, and matters arising out of or

or objections that relate to the Interests and shall have no right to seek
reimbursement or indemnification from Seller for such Title Defects or
objections.

subsidiaries, affiliates, and parents, and its and their employees,
representatives, officers, directors, attorneys and agents from and against:

            (a) any and all Losses suffered or incurred by any of them by reason
of any breached or untrue representation or warranty of Seller contained in this
Agreement, but only if a claim is initiated by Buyer by written notice to Seller
that is received within the Claims Period, unless the claim is attributable to a
breach by Seller of Section 6.2 (Title);

            (b) any and all Losses suffered or incurred by any of them by reason
of the non-fulfillment of any covenant or agreement by Seller contained in this
Agreement; and

<PAGE>

            (a) any and all Losses suffered or incurred by any of them by reason

            (b) any and all Losses suffered or incurred by any of them by reason

      7.5 Notification and Defense of Claims or Actions.

            (a) As used in this Article 7, any party seeking indemnification
pursuant to this Article 7 is referred to as an "indemnified party" and any
party from whom indemnification is sought pursuant to this Article 7 is referred
to as an "indemnifying party." An indemnified party which proposes to assert the
right to be indemnified under this Article 7 shall submit a written demand for
indemnification within fifteen (15) business days of becoming aware of such
potential claim setting forth in summary form the facts as then known which form
the basis for the claim for indemnification; provided, however, that the failure
to give such notice will not affect such claim of indemnification except to the
extent of actual prejudice to the indemnifying party. With respect to claims
based on actions by third parties, an indemnified party shall, within fifteen
(15) business days after the receipt of notice of the commencement of any
Proceeding against it in respect of which a claim for indemnification is to be
made against an indemnifying party, notify the indemnifying party in writing of
the commencement of such Proceeding, enclosing a copy of all papers served;
provided, however, that the failure to so notify the indemnifying party of any
such Proceeding shall not relieve the indemnifying party from any liability
which it may have to the indemnified party, except to the extent that the
indemnifying party is prejudiced thereby. Thereafter, the indemnified party
shall deliver to the indemnifying party, within fifteen (15) days after receipt
by the indemnified party, copies of all further notices relating to such claim.

            (b) If an indemnified party gives notice to the indemnifying party
pursuant to Section 7.5(a) of the assertion of a third-party claim, the
indemnifying party shall be entitled to participate in the defense of such
third-party claim and, to the extent that it wishes, to assume the defense of
such third-party claim with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such third-party claim, the indemnifying party
shall not, so long as it diligently conducts such defense, be liable to the
indemnified party under this Article 7 for any fees of other counsel or any
other expenses with respect to the defense of such third-party claim, in each
case subsequently incurred by the indemnified party in connection with the
defense of such third-party claim, other than reasonable costs of investigation.
If the indemnifying party assumes the defense of a third-party claim, (i) such
assumption will conclusively establish for purposes of this Agreement that the
claims made in that third-party claim are within the scope of and subject to
indemnification, and (ii) no compromise or settlement of such third-party claims
may be effected by the indemnifying party without the indemnified party's
consent unless (A) there is no finding or admission of any violation of law or
governmental rule or regulation or any violation of the rights of any person or
entity; (B) the sole relief provided is monetary damages that are paid in full
by the indemnifying party; and (C) the indemnified party shall have no liability
with respect to any compromise or settlement of such third-party claims effected
without its consent. If notice is given to an indemnifying party of the


                                      -11-
<PAGE>

assertion of any third-party claim and the indemnifying party does not, within
ten (10) days after the indemnified party's notice is given, give notice to the
indemnified party of its election to assume the defense of such third-party
claim, the indemnifying party will be bound by any determination made in such
third-party claim or any compromise or settlement effected by the indemnified
party. Any control of the defense of a third-party claim given to an
indemnifying party pursuant to this Section 7.5(b) shall, upon notice from the
indemnified party, be reversed and given back to the indemnified party if, at
any point during the course of such third-party claim the conditions necessary
to have been met to allow such indemnifying party to so control such defense are
no longer true whether because all unsatisfied claims increase in amount or
because any other factors arise.

            (c) In the event that any claim for indemnification is made with
respect to any third-party claim pursuant to this Article 7, (i) the party
assuming primary responsibility for the defense of such claim shall at all times
keep the other party reasonably informed as to the status of such claim and (ii)
the party not primarily responsible for the defense of such claim shall
cooperate fully with the other party in connection with such defense.

      7.6 Sole Remedy. The sole remedy of the Parties for any and all claims
against the other Party with respect to this Agreement shall be a claim for
indemnification under this Article 7 on the terms and subject to the conditions
of this Agreement, except for claims of willful or intentional misconduct or
fraud.

      7.7 General Liability Limitation. Notwithstanding anything contained in
this Agreement to the contrary, Seller shall not be required to indemnify or
otherwise compensate Buyer for aggregate Losses in excess of the Purchase Price;
provided, however, that such limitation of Seller's liability shall not apply to
claims resulting from Seller's gross negligence, willful misconduct or fraud.

                                    ARTICLE 8
                                  MISCELLANEOUS

      8.1 Fees and Taxes. Except as otherwise specifically provided, all fees,
costs and expense incurred by Buyer or Seller in negotiating this Agreement or
in consummating the transactions contemplated by this Agreement shall be paid by
the Party incurring the same, including, without limitation, legal and
accounting fees, costs and expenses. All required documentary, filing and
recording fees for the assignments, conveyance or other instruments required to
convey title to the Interests to Buyer shall be borne by Buyer. In addition, the
liability for any sales, use, transfer or similar tax associated with the sale
and/or transfer of the Interests shall be the liability of, and for the account
of, the Buyer.

      8.2 Notices. Unless otherwise provided in this Agreement, any agreement,
notice, request, instruction or other communication to be given hereunder by any

<PAGE>

good faith attempt to make reasonable accommodations, either Party may make any

or "belief" shall mean (except as otherwise provided in this sentence) the
actual knowledge, information or belief, as appropriate to the context of the
statement in which the term is used, of any principal shareholder or of any
officer or director of the relevant Party, or the knowledge, information or

      9.1 Selection of Arbitrators. Any controversy between the Parties hereto
arising under this Agreement, and not resolved by negotiation and agreement,
shall be determined by a board of arbitration upon notice of submission given by
either Party to the other, which notice shall name a qualified, independent
arbitrator. Within ten (10) days after the receipt of such notice, the other
Party shall name a qualified, independent arbitrator, or failing to do so, the
Party giving notice shall name the second. The two arbitrators so appointed
shall name the third qualified, independent arbitrator. Any board of arbitration
called pursuant to this section shall take place in Houston, Texas.

      9.2 Determination. The arbitrators selected to act hereunder shall be
qualified by education and experience to pass on the particular question in
dispute. The arbitrators shall promptly hear and determine (after due notice of
hearing and giving the parties a reasonable opportunity to be heard) the
questions submitted, and shall render their decision within sixty (60) days
after appointment of the third arbitrator. If within said period a decision is
not rendered by the board, or majority thereof, new arbitrators may be named and
shall act hereunder at the election of either Buyer or Seller in like manner as
if none had been previously named.

      9.3 Decision Binding. The decision of the arbitrators, or the majority
thereof, made in writing shall be final and binding upon the Parties hereto as


                                      -15-
