of its duties under this Agreement shall occupy the position of an independent
contractor with respect to the Company. Nothing contained herein shall be

Price Index, All Urban Consumers (CPI-U), U.S. City Average (All Items Category)
with a standard reference base period of 1982-84 =100 (The "CPI"). The
Management Fee shall be calculated for each subsequent year by first determining

of each fiscal trimester. In the final trimester of each fiscal year, a final
payment will be made following the annual audit and within one hundred five
(105) days of the end of the fiscal year. This final payment, when added to the
trimester Incentive Bonus payments, will adjust the Annual Incentive Bonus to

income taxes for the fiscal year.

arbitrators shall issue a written opinion setting forth their findings of fact,
conclusions of law and decision. The arbitrators' decision may be reduced to
judgment in a court of law. The arbitrators so chosen shall conduct the

in their determinations hereunder, by the intention of the parties as evidenced
by the terms of this Agreement. After signing this Agreement, each party
understands that it will not be able to bring a lawsuit concerning any dispute
that may arise that is covered by this arbitration provision, unless it involves
a question of constitutional law or civil rights. Instead, each party agrees to
submit disputes to binding impartial arbitration as provided herein.

         This Agreement shall be assignable by either party upon mutual written

events over which Manager and Manager's Price Risk Consultant have no control.

by Company for any losses related to the trading activities of Manager and
Manager's Price Risk Consultant relating to this Agreement so long as Manager

they reasonably believed to be in the best interests of the business of the
Plant. The parties acknowledge that the price risk management services to be
rendered pursuant to this Agreement may affect the profitability of the Plant,
