         by Company shall continue for ten (10) days from the date payment is
         due.

Termination of this U.S. Shippers Service Agreement shall not relieve Company

hereunder, or Shipper to pay money due hereunder to Company and shall be in
addition to any other remedies that Company may have.

ARTICLE 8 - APPLICABLE LAW AND SUBMISSION TO JURISDICTION

This Service Agreement and Company's Tariff, and the rights and obligations of
Company and Shipper thereunder are subject to all relevant United States lawful
statutes, rules, regulations and orders of duly constituted authorities having
jurisdiction. Subject to the foregoing, this Service Agreement shall be governed
by and interpreted in accordance with the laws of the State of Nebraska. For
purposes of legal proceedings, this Service Agreement shall be deemed to have
been made in the State of Nebraska and to be performed there, and the Courts of
that State shall have jurisdiction over all disputes which may arise under this
Service Agreement, provided always that nothing herein contained shall prevent
the Company from proceeding at its election against the Shipper in the Courts of
any other state, Province or country.

At the Company's request, the Shipper shall irrevocably appoint an agent in
Nebraska to receive, for it and on its behalf, service of process in connection
with any judicial proceeding in Nebraska relating to this Service Agreement.
Such service shall be deemed completed on delivery to such process agent (even
if not forwarded to and received by the Shipper). If said agent ceases to act as
a process agent within Nebraska on behalf of Shipper, the Shipper shall appoint
a substitute process agent within Nebraska and deliver to the Company a copy of
the new agent's acceptance of that appointment within 30 days.

ARTICLE 9 - SUCCESSORS AND ASSIGNS

Any person which shall succeed by purchase, amalgamation, merger or
consolidation to the properties, substantially as an entirety, of Shipper or of
Company, as the case may be, and which shall assume all obligations under
Shipper's Service Agreement of Shipper or Company, as the case may be, shall be
entitled to the rights, and shall be subject to the obligations, of its
predecessor under Shipper's Service Agreement. Either party to a Shipper's
Service Agreement may pledge or charge the same under the provisions of any
mortgage, deed of trust, indenture, security agreement or similar instrument
which it has executed, or assign such Service Agreement to any affiliated Person
(which for such purpose shall mean any person which controls, is under common
control with or is controlled by such party). Nothing contained in this Article
9 shall, however, operate to release predecessor Shipper from its obligation
under its Service Agreement unless Company shall, in its sole discretion,
consent in writing to such release, which it shall not do unless it concludes
that, on the basis of the facts available to it, such release is not likely to
have a substantial adverse effect upon other Shippers or other Persons who may
become liable to provide funds to Company to enable it to meet any of its
obligations. Company shall not release any Shipper from its obligations under
its Service Agreement without the written consent of the other Shippers unless:
(a) such release is effected pursuant to an assignment of obligations by such
Shipper, and the assumption thereof by the assignee, and the terms of such
assignment and assumption render the obligations being assigned and assumed no
more conditional and no less absolute than those at the time provided therein;
and (b) such release is not likely to have a substantial adverse effect upon
Company or the other Shippers. For the purposes hereof, and without limiting the
generality of the foregoing, any release of any Shipper from its obligations
under its Service Agreement shall be deemed likely to have a substantial adverse
effect upon Company or the other Shippers if the assignee of such obligations
has a credit standing which is not at least equal to the credit standing of the
assignor of such obligations (credit standings in each case as reflected by the
ratings on outstanding debt securities by Moody's Investors Service, Standard
and Poor's Corporation or another rating service acceptable to all Shippers to
the extent available or by other appropriate objective measures). Shipper shall,
at Company's request, execute such instruments and take such other action as may
be desirable to give effect to any such assignment of Company's rights under
such Shipper's Service Agreement or to give effect to the right of a Person whom
the Company has specified pursuant to Section 6 of the General Terms and
Conditions of Company's FERC Gas Tariff as the Person to whom payment of amounts
invoiced by Company shall be made; provided, however, that: (a) Shipper shall
not be required to execute any such instruments or take any such other action
the effect of which is to modify the respective rights and obligations of either
Shipper or Company under this Agreement; and (b) Shipper shall be under no
obligation at any time to determine the status or amount of any payments which
may be due from Company to any Person whom the Company has specified pursuant to
said Section 6 as the Person to whom payment of amounts invoiced by Company
shall be made.

ARTICLE 10 - LOSS OF GOVERNMENTAL AUTHORITY, GAS SUPPLY, TRANSPORTATION OR
MARKET

Without limiting its other responsibilities and obligations under this Service
Agreement, the Shipper acknowledges that it is responsible for obtaining and
assumes the risk of loss of the following: (1) gas removal permits, (2) export
and import licenses, (3) gas supply, (4) markets and (5) transportation upstream
and downstream of the Company's pipeline system. Notwithstanding the loss of one
of the items enumerated above, Shipper shall continue to be liable for payment
to the Company of the transportation charges as provided for in this Service
Agreement.

ARTICLE 11 - OTHER OPERATING PROVISIONS

(This Article to be utilized when necessary to specify other operating
provisions.)

ARTICLE 12 - EXHIBIT A OF SERVICE AGREEMENT, RATE SCHEDULES AND GENERAL TERMS
             AND CONDITIONS

Company's Rate Schedules and General Terms and Conditions, which are on file
with the Federal Energy Regulatory Commission and in effect, and Exhibit A
hereto are all applicable to this Service Agreement and are hereby incorporated
in, and made a part of, this Service Agreement. In the event that the terms and
conditions herein are in conflict with the General Terms and Conditions in
Company's FERC Gas Tariff, the terms and conditions of this Service Agreement
are controlling.

IN WITNESS WHEREOF, The parties hereto have caused this Agreement to be duly
executed as of the day and year first set forth above.
