                  3.3(f).2. Deliverables. Borrower shall deliver to Lender the
following items, all to be satisfactory to Lender, in its sole discretion, and

occupancy, and commencement of paying rent, by tenants pursuant to lease(s) (the
"Lease(s)") approved by Lender demising those buildings known as: [insert
description of premises of Leases that expired in 2005 and were not renewed];
provided, however, the Lease(s) must meet the following conditions: (i) have a
minimum term of three (3) years; (ii) are of market acceptable credit worthiness
as approved by Lender which approval shall not be unreasonably withheld; (iii)
provide for a market rent, but the minimum of which (when combined with other

commencing on the date on which the last of such Lease(s) meet the conditions
above) not less than 1.30:1.00.

         3. Presentment of Letter of Credit. Lender may present the Letter of
Credit for payment, in full or in part, upon the occurrence and during the
continuation of an Event of Default (as defined in the Loan Agreement). Any such
occurrence of an Event of Default as set forth in this paragraph is hereinafter
referred to as a "Presentment Event." Borrower expressly covenants and agrees
that Lender has the unconditional right to present the Letter of Credit upon the
occurrence of a Presentment Event, by clean sight draft and without other
documentation, certification or statement. Any failure or delay of Lender to
present the Letter of Credit shall not act as a waiver of Lender's right to do
so at any time during the continuation of such Presentment Event or constitute a
waiver of any default hereunder.

         4. Application of Proceeds. Upon receipt of the proceeds of the Letter
of Credit (the "Proceeds"), Lender shall apply such Proceeds, at its option,
either to cure Borrower's default or, upon notice to Borrower if no notice is
otherwise required under the Loan Documents, to payment of the outstanding
principal balance of the Loan plus accrued unpaid interest and costs thereon.

         5. Interference with Payment; Indemnification. Borrower agrees not to
interfere in any way with payment by Bank to Lender of the Proceeds of the
Letter of Credit, either prior to or following presentment by Lender of the
Letter of Credit, regardless of whether any dispute exists between Borrower and
Lender as to Lender's right to present the Letter of Credit; provided, however,
that such agreement shall not be a waiver of any other right or claim Borrower
may have against Lender. Borrower shall be liable to Lender for any loss, cost
or expense suffered by Lender as a result of such interference, including,
without limitation, any reasonable attorneys' and paralegals' fees and costs.
Without limiting the duty to return the Letter of Credit as set forth in Section
2 hereof, no condition or term of this Agreement shall be deemed to render the
Letter of Credit conditional upon this Agreement or to justify the issuer of any
Letter of Credit in failing to honor a draw upon the Letter of Credit in a
timely manner.

         6. Security for Borrower's Obligation. Borrower acknowledges and agrees
that it is intended that the Letter of Credit is given as security for the
performance of the obligations of Borrower under the Loan Documents and the
performance of the obligations of Borrower under this Agreement.
