EARLY TERMINATION:                                   In the event that any item of Equipment is (i) damaged or
                                                     destroyed to such extent that it cannot be reasonably restored to
                                                     normal operating condition or (ii) seized or condemned by
                                                     governmental authorities (i.e. eminent domain) or (iii) lost due
                                                     to theft or disappearance for a period in excess of 45 days, the

                                                     thereto.

NET LEASE:                                           The Lease will be a net lease in that the Lessee will be
                                                     responsible for any and all costs and expenses in connection with
                                                     the Equipment, including sales and use taxes, and any other taxes
                                                     with the exception of federal and state net income taxes on the
                                                     net income of the Lessor.  The Lessee is also responsible for
                                                     maintaining and insuring the Equipment and for all fees;
                                                     insurance premiums; cost of installation, operations,
                                                     maintenance, repair, and rebuilding; and other charges related to
                                                     the use or possession of the Equipment.

FEDERAL TAX INDEMNIFICATIONS:                        The Lessee will indemnify the Lessor for any loss or deduction in
                                                     federal tax benefits based on the tax assumptions outlined above
                                                     if such loss or reduction is caused by (i) any breach, inaccuracy
                                                     or incorrectness of any representation, warranty or covenant made
                                                     by the Lessee, (ii) the acts or omissions (not including the
                                                     execution of documents contemplated hereby or any act or omission
                                                     expressly required or expressly permitted by such documents) of
                                                     the Lessee, or (iii) any change in federal  law with an effective
                                                     date that precedes the date of acceptance of the Equipment for
                                                     lease by the Lessee.  If an Investment Tax Credit provision is
                                                     passed, benefit will flow to Lessee at the same lease rate as
                                                     indicated in this proposal.

MAINTENANCE:                                         Lessee will maintain the Equipment leased by it so that it remains
                                                     in good operating condition (ordinary wear and tear excepted) and
                                                     in compliance with any and all applicable laws, regulations, and
                                                     state inspections.

END OF TERM OPTIONS:                                 At the end of the Basic Term, the Lessee shall have the option of
                                                     purchasing the Equipment or returning the Equipment to the Lessor
                                                     in accordance with the terms described below.

TERMINATION:                                          At the satisfactory conclusion of the Basic Term, the Lessee shall
                                                      have the option to purchase all, but not less than all, of the
                                                      equipment on a Lease Schedule. In this event, the Lessee will have
                                                      a purchase price as follows:

                                                      Forty Percent (40%) of the Equipment Cost

                                                      In the event the Lessee chooses to return the Equipment, the
                                                      Lessor will sell the Equipment. If the Net Proceeds of the sale
                                                      (after expenses) are greater than the Purchase Price, the excess
                                                      proceeds will be returned to the Lessee. If the Net Proceeds are
                                                      less than the Purchase Price, the difference between the proceeds
                                                      and the Purchase Price will be paid by the Lessee to the Lessor as
                                                      a final Rental Payment then due.

DOCUMENTATION:                                        This Proposal is not intended to address all the final legal and
                                                      documentation matters pertaining to this lease. The lease
                                                      documentation will represent the final legal agreement. The lease
                                                      documentation will be furnished by the Lessor.
