Section 2.1    Loans

         (a)   Amount. Lender agrees, upon the terms and conditions herein set
forth, to make a loan or loans to Borrower from time to time and from the
Closing Date until ten (10) days after Borrower has notice that no further
advances of loan proceeds are available under the Key Credit Agreement, each in

not exceed Ten Million Dollars ($10,000,000) (the "Commitment") (each such loan
is herein referred to as the "Loan," all such loans are herein referred to as
"Loans," and the aggregate amount of all such Loans outstanding from time to
time, the "Loan Amount").

         (b)   Borrowings. In the event that Borrower shall elect to borrow
pursuant hereto, the Borrower shall give written notice to the Lender not later
than three (3) Business Days prior to the proposed date of such borrowing. Each
such notice of borrowing shall be by telecopy, promptly confirmed by letter, and
shall specify therein: (i) the date of such proposed borrowing, which shall be a
Business Day; (ii) the amount of such proposed borrowing which, when aggregated
together with the amount of all Loans then outstanding, shall not exceed the
Commitment; and (iii) the bank account or accounts to which the proceeds of such
Loan should be paid by Lender. The obligations of Borrower to repay the Loans
shall be evidenced by Borrower's promissory note in the form attached hereto as
Exhibit A, dated the Closing Date and payable to the order of Lender for the
principal sum of $10,000,000 or such Loan Amount as shall be outstanding
hereunder from time to time, with interest as therein provided.

         (c)   Payments. Unless payment of the Loans are accelerated upon
occurrence of an Event of Default pursuant to Section 7.2 hereof, i) the
aggregate outstanding principal amount of the Loans relating to a Project,
together with all accrued and unpaid interest thereon, shall be due and payable
in full on the maturity date of the Key Project Loan for such Project, and ii)
accrued interest on Loans relating to a Project shall be payable quarterly;
provided that, while the Intercreditor Agreement is in effect, no such principal
and interest shall be payable to the extent and for the period that the
Intercreditor Agreement prohibits such payment. However, if the Intercreditor
Agreement's payment prohibition is not due to the default of the Lender under
the Guaranty or to the breach of the Lender under any Management Agreement or
Development Agreement, then such amounts due and payable but so prohibited shall
be deemed paid on the date due with proceeds of, and shall be deemed advances
under the Convertible Subordinated Loan Agreement dated the date of this

Agreement between the Lender and the Borrower.

         (d)  Interest Rate. The Loans shall bear interest, during the period
from and including the date of funding to (but not including) the date the Loans
are paid in full, at the per annum rate set forth in the Note.

Section 2.2   Prepayment.

         The principal amount of the Loans may be repaid or prepaid in full or
in part at any time prior to the date payments of principal are due, without
premium or penalty.

Section 2.3   Manner of Payment.

         (a)  Each payment (including prepayments) by Borrower on account of
the principal or interest on the Loans shall be made on the dates specified for
payment under this Agreement (or, as to prepayments, any date specified by
Borrower) to the Lender in lawful money of the United States of America in
immediately available funds.

         (b)  If any payment under this Agreement shall be specified to be made
upon a day which is not a Business Day, it shall be made on the next succeeding
day which is a Business Day, and such extension of time shall in such case be
included in computing interest, if any, in connection with such payment.

         (c)  Amounts received by Lender with respect to Loans shall be applied
in the following order of priority: (i) to the payment of all amounts then due
and payable under this Agreement other than interest or principal; (ii) to the
payment of interest then due and payable on the Loans; and (iii) to the
repayment or prepayment of the principal balance of the Loans.

Section 2.4   Basis of Calculation of Interest.

         All interest payable hereunder shall be calculated on the basis of the
360/365 method, which computes a daily amount of interest for a hypothetical
year of 360 days, then multiplies such amount by the actual number of days
elapsed in an interest calculation period.

Section 2.5   Maximum Interest Rate.

         In no event shall the amount of interest due or payable under the Note
exceed the maximum rate of interest allowed by applicable law, and in the event
that any such payment is inadvertently paid by Borrower or inadvertently
received by Lender, then such excess sum shall be credited as a payment of
principal, unless Borrower shall notify Lender, in writing, that Borrower elects
to have such excess sum returned to it forthwith. It is the express intent
hereof that Borrower not pay, and that Lender not receive, directly or
indirectly, in any manner whatsoever, interest in excess of that which would
lawfully be paid by Borrower under applicable law.

or right, and no course of dealing between Borrower and Lender, shall operate as

power or right preclude other or further exercise thereof or the exercise of any
other power or right. Remedies provided for herein are cumulative and not
exclusive of any remedies which may be available to the Lender at law or in
equity. No notice to or demand on the Borrower required hereunder or under the
Note shall in any event entitle Borrower to any other or further notice or
demand in similar or other circumstances or constitute a waiver of the right of
Lender to any other or further action and any circumstances without notice or
demand. No amendment, modification or waiver of, or consent with respect to, any
provision of this Agreement or the Note shall in any event be effective unless
the same shall be in writing and signed and delivered by the party affected by
such amendment or modification or making the waiver. Any waiver of any provision
of this Agreement or the Note, and any consent to any departure by Borrower from
the terms of any provision of this Agreement or the Note, shall be effective
