Agreement, the other Ancillary Agreements, and the Exhibits and Schedules
attached hereto and thereto, constitute the entire agreement between the parties
with respect to the subject matter hereof and thereof and shall supersede all

understandings with respect to the subject matter hereof and thereof.

     Section 8.4. GOVERNING LAW. This Agreement shall be governed and construed

matters, regardless of the laws that might otherwise govern under the principles
of conflicts of laws applicable thereto.

Agreement unless otherwise indicated.

     Section 8.6. NOTICES. Any notice, demand, offer, request, or other

consent, and any attempted assignment or transfer without such prior written
consent shall be voidable at the sole option of UtiliCorp. This Agreement,
including the Schedules and the other documents referred to herein, shall be
binding upon and inure to the benefit of each party hereto and their respective
legal representatives and permitted successors and assigns, and nothing in this
Agreement, express or implied, is intended to confer upon any other Person any
rights or remedies of any nature whatsoever under or by reason of this
Agreement.

     Section 8.8. SEVERABILITY. If any term or other provision of this Agreement
is determined by a nonappealable decision by a court, administrative agency or
arbitrator to be invalid, illegal or incapable of being enforced by any rule of
law or public policy, all other conditions and provisions of this Agreement
shall nevertheless remain in full force and effect so long as the economic or
legal substance of the transactions contemplated hereby is not affected in any
manner materially adverse to either party. Upon such determination that any term
of other provision is invalid, illegal or incapable of being enforced, this
Agreement shall be deemed to be amended, and each party agrees to execute and
deliver such documents and instruments as are reasonably requested by the other
party to evidence such amendment, so as to effect the original intent of the
parties as closely as possible in an acceptable manner to the end that the
transactions contemplated hereby are fulfilled to the fullest extent possible.

     Section 8.9. FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE. No
failure or delay on the part of either party hereto in the exercise of any right
hereunder shall impair such right or be construed to be a waiver of, or
acquiescence in, any breach of any representation, warranty or agreement herein,
nor shall any single or partial exercise of any such right preclude any other or
further exercise thereof or of any other right. All rights and remedies existing
under this Agreement are cumulative to, and not exclusive of, any rights or
remedies otherwise available.

     Section 8.10. AMENDMENT. No change or amendment will be made to this
Agreement except by an instrument in writing signed on behalf of each of the
parties hereto.

member of the Aquila Group against any and all obligations of Aquila now or
hereafter arising under this Agreement, whether or not UtiliCorp shall have made
any demand therefor.
