whole (but not in part without the prior written consent of the holder), on

Bonds are subject to optional redemption under the Indenture, upon payment of 
an amount equal to 100% of the principal amount to be prepaid, together with 
interest accrued thereon to the first day of the month following the date of 
such prepayment and any other sums due Lender at the time of such prepayment; 
provided, however, that as a prerequisite to the right to make any such 
voluntary prepayment, Borrower shall give written notice to Lender and to the 
Trustee at least sixty (60) days prior to such prepayment, which notice shall 
state the date of such prepayment, the amount of principal to be prepaid, the 
amount of interest accrued and the amount of other sums due Lender at the 
time of such prepayment; and provided, further, that, as a condition to its 
acceptance of the prepayment, Lender shall have been provided with a 
certificate of the Trustee to the effect that the Trustee holds on deposit 
Eligible Funds (as defined in the Indenture) that are both sufficient and 
available under the terms of the Indenture for payment of any premium, costs 
and expenses required to be paid in connection with the redemption of the 
Bonds to be redeemed as a result of the prepayment hereunder.

provisions, Borrower must satisfy the applicable conditions set forth in 
Section 4.3 of the Reimbursement Agreement with respect to release of the 
Property from the lien of the Instrument in connection with any full 
prepayment of the Note.

C.       PARTIAL PREPAYMENTS

         Any partial prepayments of principal of the Note (following the last
Business Day of June, 2006 or from condemnation awards or insurance proceeds)
shall be applied against the outstanding principal balance of the Note and shall
not extend or postpone the due date of any subsequent monthly installments,
except as hereinafter provided.  The amount of any

                                         -3-




such subsequent monthly installments shall be decreased as necessary to amortize
the remaining principal balance hereof at the interest rate then in effect
hereunder over a period equal to 360 months minus the number of months in which
regularly scheduled monthly installments of principal and interest shall have
previously become due from and including the amortization commencement date;
provided, however, that all indebtedness evidenced by the Note shall be due and
payable on the maturity date set forth in the Note, if not sooner paid.

D.       CROSS-DEFAULT

         The failure by Borrower to pay when due any amount payable under the
Note, the Instrument or any other Loan Document or the failure (beyond
applicable cure periods, if any) by the Borrower to perform or observe any other
covenant or obligation of the Borrower contained in (a) the Note, the Instrument
or any other Loan Document, (b) any of the documentation relating to the Bonds,
including without limitation the Financing Agreement, (c) any subordinate
financing, (d) the Regulatory Agreement, (e) the Reimbursement Agreement, or (f)
any form of public, quasi-public, public/private or private debt and/or equity
infusion, grant, subsidy, tax relief or abatement plan, program or other form of
assistance shall, at Lender's option, in its discretion, constitute a default
under the Note, the Instrument and each of the other Loan Documents. Any such
default shall: (i) entitle Lender, at its option and in its discretion, to
invoke any of the remedies set forth in paragraph 27 of the Instrument or as
otherwise afforded by law or in equity; and (ii) at Fannie Mae's option, in its
discretion, constitute an "Event of Default" under and in accordance with the
terms of the Reimbursement Agreement. Notwithstanding anything herein to the
contrary, the provisions of clause(e) and/or clause (ii) above of this Paragraph
D shall become null and void and of no further force or effect upon: (i) a
transfer of the Property and assumption of the Note pursuant to Section 4.5 of
the Reimbursement Agreement; and (ii) written notice from Fannie Mae to the
Borrower and the "Permitted Transferee" (as defined in the Reimbursement
Agreement) confirming that such provisions are of no further force or effect.

E.       ASSIGNMENT TO FANNIE MAE

         In the event the Note is assigned to Fannie Mae on a day other than
the first day of a month, Borrower shall nevertheless pay to Fannie Mae, in
full, the next installment of principal, if any, and interest on the first day
of the succeeding month, including an amount equal to one full month's interest,
without regard to any payment which Borrower may have made to any other party
with respect to the month within which the assignment occurs.

F.       CHOICE OF LAW; CONSENT TO JURISDICTION. The provisions of Section 7.8
and Section 7.9 of the Reimbursement Agreement are hereby incorporated by
reference herein as if fully set forth herein.
