INCLUDING THE NEGLIGENCE OF ANY PARTY, WHETHER SUCH NEGLIGENCE BE SOLE, JOINT OR

13.
            Force
      Majeure.





13.1           In
the event that either Party is rendered unable, by reason of an event of force
majeure, to perform, wholly or in part, any obligation or commitment set forth
in this Agreement, then upon such Party's giving notice and full particulars of
such event of force majeure, this Agreement shall be suspended, except for the
payment of monies owed hereunder, to the extent and for the period that such

condition.  Initial notice may be given orally; however, written

otherwise, not reasonably within the control of the Party claiming force
majeure.




14.
            Events of Default;
      Termination.





14.1           It
shall be an “Event of Default” if:




(a)
            Either
      Party becomes insolvent, makes an assignment for the benefit of creditors,
      or a receiver or trustee is appointed for the benefit of such Party’s
      creditors, or a Party makes a filing for protection from creditors under
      any bankruptcy or insolvency laws, or such filing is made against a
      Party;




(b)
            Buyer
      fails to make any payment when due and such nonpayment shall
      have













continued for ten (10) Days or
more after written notice of same from Seller; or




(c)
            Either
      Party fails to perform any of its material obligations hereunder and such
      nonperformance shall have continued for thirty (30) Days or more after
      notice of same from the other
Party.




14.2           If
an Event of Default occurs and is continuing, the non-defaulting Party may, by
written notice to the defaulting Party, designate a day no earlier than the day
such notice is effective as an early termination date ("Early Termination
Date").  On the Early Termination Date, all obligations due on or
after the Early Termination Date under the Agreement shall be terminated except
as provided herein.  If an Early Termination Date has been designated,
the non-defaulting Party shall in good faith calculate the amount due between
the parties as of the Early Termination Date. The non-defaulting party shall
notify the defaulting Party in writing of the amount due and whether it is owed
to or from the defaulting Party (the “Termination Payment”).  The
party owing the Termination Payment shall pay it to the other party within two
(2) Business Days after the effective date of such notice, with interest at the
Base Rate from the Early Termination Date until paid.




In
addition, the defaulting Party hereunder shall reimburse the non-defaulting
Party, on demand, for actual, reasonable out-of-pocket expenses (with interest
at a rate equal to the lower of (i) the then-effective prime rate of interest
published under “Money Rate” by The Wall Street Journal, plus two percent per
annum; or (ii) the maximum applicable lawful interest rate), including, without
limitation, reasonable legal fees and expenses incurred by the other Party in
connection with the enforcement of the Agreement.




If an
Early Termination Date is designated, the non-defaulting party shall be
entitled, in its sole discretion, to set-off any amount payable by the
non-defaulting Party to the defaulting Party under the Agreement or otherwise,
against any amounts payable by the defaulting Party to the non-defaulting Party
under this Agreement or otherwise.  This provision shall be in
addition to any right of setoff or other right and remedies to which any party
is otherwise entitled (whether by operation of law, contract or
otherwise).  If an obligation is unascertained, the non-defaulting
party may in good faith estimate that obligation and set-off in respect of the
estimate, subject to the non-defaulting party accounting to the defaulting Party
when the obligation is ascertained.




15.
            Miscellaneous.




15.1           This
Agreement shall be binding upon and inure to the benefit of the successors and
assigns of the respective Parties hereto, and the covenants, conditions, rights
and obligations of this Agreement shall run for the full term of this
Agreement.  No assignment of this Agreement, in whole or in part, will
be made without the prior written consent of the non-assigning Party, which
consent will not be unreasonably withheld or delayed; provided, either Party may
(i) transfer, sell, pledge, encumber, or assign this Agreement or the accounts,
revenues, or proceeds hereof in connection with any financing or other financial
arrangements, or (ii) transfer its interest to any parent or Affiliate by
assignment, merger or otherwise without the prior approval of the other
Party.  Upon any such assignment, transfer and assumption, the
transferor shall remain principally liable for and shall not be relieved of or
discharged from any obligations hereunder.




15.2           The
invalidity of any one or more covenants or provisions of this Agreement shall
not affect the validity of any other provisions hereof or this Agreement as a
whole, and in case of any such invalidity, this Agreement shall be construed to
the maximum extent possible as if







such
invalid provision had not been included herein.  No waiver of any
breach of this Agreement shall be held to be a waiver of any other or subsequent
breach.




15.3           This
Agreement sets forth all understandings between the Parties respecting each
transaction subject hereto, and any prior Agreements, understandings and
representations, whether oral or written, relating to such transactions are
merged into and superseded by this Agreement and any effective
transaction(s).  This Agreement may be amended only by a writing
executed by both Parties.  Each Party shall take such acts and execute
and deliver such documents as may be reasonably required to effectuate the
purposes of this Agreement.




15.4           The
interpretation and performance of this Agreement shall be governed by the laws
of the State of Texas, excluding, however, any conflict of laws rule which would
apply the law of another jurisdiction.  This Agreement and all
provisions herein will be subject to all applicable and valid statutes, rules,
orders and regulations of any governmental authority having jurisdiction over
the Parties, their facilities, Gas supply, this Agreement or transaction or any
provisions thereof.  The Parties shall comply with all applicable laws
in the performance of their respective obligations under this
Agreement.




15.5           Each
Party to this Agreement represents and warrants that it has full and complete
authority to enter into and perform this Agreement.  Each person who
executes this Agreement on behalf of either Party represents and warrants that
it has full and complete authority to do so and that such Party will be bound
thereby.




15.6           The
provisions of Section 14.2 and Article 12, shall survive any expiration or
termination of this Agreement.




15.7           Nothing
in this Agreement shall entitle any person other than Seller or Buyer, or their
successors or assigns, to any claim, cause of action, remedy or right of any
kind relating to the transaction(s) contemplated by this Agreement.




15.8           In
construing this Agreement, the following principles shall be followed: (i) no
consideration shall be given to the fact or presumption that one Party had a
greater or lesser hand in drafting this Agreement; (ii) examples shall not be
construed to limit, expressly or by implication, the matter they illustrate;
(iii) the word “includes” and its syntactical variants mean “includes, but is
not limited to” and corresponding syntactical variant expressions; (iv) the
plural shall be deemed to include the singular and vice versa, as applicable,
and (v) unless the context otherwise requires, any reference to a statutory
provision (including those contained in subordinate legislation) is a reference
to the provision as amended or re-enacted, or as modified by other statutory
provisions from time to time, and includes subsequent legislation made under the
relevant statute.
