<PAGE>

        14.2 Conduct of the Arbitration, Authority of the Arbitrators, and
Choice of Law. Arbitration shall be conducted in accordance with the rules of
arbitration of the Federal Arbitration Act and, to the extent an issue is not
addressed by the federal law on arbitration, by the Commercial Arbitration Rules
of the American Arbitration Association. The validity, construction, and
interpretation of this agreement to arbitrate, and all procedural aspects of the
arbitration conducted pursuant hereto shall be decided by the arbitrators. In
deciding the substance of the Parties' Claims, the arbitrators shall refer to
the laws of the State of Texas as required by Section 15.8 hereof. It is agreed
that the arbitrators shall have no authority to award treble, exemplary or
punitive damages of any type under any circumstances whether or not such damages
may be available under state, or federal law, or under the Federal Arbitration
Act, or under the Commercial Arbitration Rules of the American Arbitration
Association, the Parties hereby waiving their right, if any, to recover any such
damages.

        14.3 Forum for the Arbitration and Selection of Arbitrators. The
arbitration proceeding shall be conducted in Houston, Texas. Within thirty (30)
Days of the notice of initiation of the arbitration procedure, each Party shall
select one arbitrator. The two arbitrators shall select a third arbitrator. The
third arbitrator shall be a person who has over eight (8) years professional
experience in the intrastate natural gas pipeline industry and who has not
previously been employed by either Party and does not have a direct or indirect
interest in either Party or the subject matter of the arbitration. While the
third arbitrator shall be neutral, the two Party-appointed arbitrators are not
required to be neutral, and it shall not be grounds for removal of either of the
two Party-appointed arbitrators or for vacating the arbitrators' award that
either of such arbitrators has past or present minimal relationships with the
Party that appointed such arbitrator.

         14.4 Confidentiality. To the fullest extent permitted by law, any
arbitration proceeding and the arbitrators award shall be maintained in
confidence by the Parties.

                            15. MISCELLANEOUS CLAUSES

         15.1 Transfer. This Agreement shall inure to and bind the permitted
successors and assigns of the Parties; provided, except as permitted herein,
neither Party shall transfer this Agreement without the prior written approval
of the other Party; provided further, either Party may transfer its interest to
an Affiliate by assignment, merger or otherwise without the prior approval of
the other Party, but no such transfer shall operate to relieve the assigning
Party of its obligations hereunder; provided further, if Provider assigns all or
any part of the Fee due Provider hereunder to a third party (which Customer
agrees it shall have the right so to do without Customer's prior consent),
Customer, upon receiving written notice of any such assignment, shall make all
payments hereunder as it may be therein directed. Any Party's transfer in
violation hereof shall be void.

         15.2 Warranties. EXCEPT AS MAY BE EXPRESSLY PROVIDED HEREIN OR AS

<PAGE>

THERE ARE NO EXPRESS, STATUTORY OR IMPLIED WARRANTIES WITH RESPECT TO THIS
AGREEMENT.

         15.3 Enforceability and Irrevocability. If any part of this Agreement
is contrary to, prohibited by or deemed invalid under applicable laws or
regulations of any jurisdiction, such provision shall be inapplicable and deemed
omitted but shall not invalidate the remaining provisions hereof. Each Party
admits the receipt of a counterpart of this Agreement.

         15.4 Confidentiality and Public Statement. Each Party shall not
disclose the terms of this Agreement, or any information concerning gas
throughput or the operations of either Party it receives or has knowledge of
incident to the performance of the obligations hereunder, to a third party
(other than its Affiliates' employees, lenders, direct and indirect owners,
shareholders, partners, and/or investors, and each of such person's respective
counsel, accountants and investment advisors and other advisors who have agreed
to keep such terms confidential) except in order to comply with any applicable
law, order, regulation or exchange rule; provided, each Party shall notify the
other Party of any proceeding of which it is aware which may result in
disclosure and use reasonable efforts to prevent or limit the disclosure.
Notwithstanding the foregoing, the Parties, upon mutual written approval of both
form and content, may release public communications concerning the transaction
contemplated by this Agreement.

         15.5 Modification and Waiver. No covenant or condition of this
Agreement may be modified by either Party except by the written consent of both
Parties. Forbearance or indulgence by either Party in any regard whatsoever
shall not constitute a waiver or change of the covenant or condition to be
performed by the other Party to which the same may apply, and, until the
complete performance of said covenant or condition has occurred. Each Party
shall be entitled to invoke any remedy at law or in equity available to it under
the provisions of this Agreement despite said forbearance or indulgence. Waiver
of any defaults shall not waive any other default.

         15.6 Entirety and Relationship. This Agreement constitutes the entire
agreement of the Parties related to the provision of the Services by Provider to
Customer. There are no prior or contemporaneous agreements or representations
(whether oral or written) involving the subject matter of this Agreement other

between the Parties.

deemed to be in exclusive control and possession



                                   Schedule I
<PAGE>

thereof and responsible for any injuries or damages caused thereby until the
same shall have been redelivered for the account of Customer at the Delivery
Points.

         15.8 Law. This Agreement shall be construed under and in accordance
with the laws of the State of Texas and Federal law as set forth in Section
14.2.

         15.9 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original and need not be
signed by more than one of the Parties and all of which shall constitute one and
the same agreement.

         15.10 Other. The headings used herein are for convenience and reference
purposes only. The Parties agree that the original executed version of this
Agreement, Service Operating Schedule, Exhibit or any Services Schedule may be
photocopied and stored on computer tapes and disks, with the Parties
specifically agreeing that if such items, if introduced as evidence on paper (or
if computer records, then introduced into evidence in printed format), in any
