(“Eastgate Borrower”) each a Delaware limited liability company (Centennial
Borrower and Eastgate Borrower each individually a “Borrower”, and collectively

and assigns, “Lender”). Ladies and Gentlemen: Reference is hereby made to the
Loan Agreement. Capitalized terms not defined herein shall have the meanings
ascribed to such terms in the Loan Agreement. This letter agreement (this
“Agreement”) shall confirm our agreement as follows: Borrowers have requested
Lender to fund the Loan, notwithstanding Borrowers’ failure to deliver certain
documents, evidences and showings relating thereto. Lender, subject to the
satisfaction of the other conditions precedent to the making of the Loan, is
willing to proceed with the funding of the Loan, subject to Borrowers’
compliance with the terms of this Agreement. Accordingly, to induce Lender to
make the Loan, Borrowers agree to satisfy all of the post-closing requirements
set forth on Exhibit A attached hereto and made a part hereof (collectively the
“Post-Closing Requirements”). All acts of Borrowers to be performed hereunder
shall be at Borrowers’ sole cost and expense and shall be satisfactory to Lender
in all respects. Borrowers hereby agree to pay all of Lender’s reasonable costs
and expenses incurred in connection with its review and approval of the items
set forth herein, including, without limitation, reasonable attorney’s fees.
Failure by Borrowers to comply with any of the Post-Closing Requirements shall,
at Lender’s option, constitute an Event of Default (as defined in the Loan
Agreement) and Lender shall be entitled to exercise any and all rights and
remedies it may have under the Note, the Loan Agreement, the Mortgage and the
other Loan Documents. Nothing in this paragraph shall be deemed to (i) be a
waiver by Lender of any of its rights or remedies under the Note, the Loan
Agreement, the Mortgage or the other Loan Documents, or this Agreement upon a
default by

provisions of the Loan Agreement, the Mortgage or the other Loan Documents. This
