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

arbitrators shall issue a written opinion setting forth their findings of fact,
conclusions of law and decision. The arbitrators' decision may be reduced to

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
