     any, in such form as Lessor may request.

7.   LESSOR'S OBLIGATIONS: Lessor's obligations under this

     one-quarter of one percent (1/4 of 1%) by which the Prime
     Interest Rate (as stated by Citibank N.A.) increases prior
     to the Commencement Date, or the date Lessor has received
     sufficient documentation so as to finance the Lease,
     whichever is later.  Lessee agrees that it shall confirm the
     amount of the rental payable hereunder after adjustment, if
     any, in such form as Lessor may request.

7.   LESSOR'S OBLIGATIONS: Lessor's obligations under this
     Equipment Schedule are subject to there being no tax
     legislation enacted prior to the Installation Date which
     would have an adverse effect on the rights or anticipated
     benefits to Lessor or any Assignee.

8.   SECURITY DEPOSIT: $  0.00  .
