RECITALS:

A.            Pursuant to that certain Credit Agreement dated January 16, 2004, and amended by the First Amendment to the Credit Agreement dated May 17, 2004 and the Second Amendment to the Credit Agreement dated January 30, 2006, (as amended, the “Credit Agreement”) between Mortgagor and Mortgagee, Mortgagee has provided Mortgagor a loan in the original principal amount of $33,500,000.00 as evidenced by two promissory notes dated as of January 16, 2004, given by Mortgagor in favor of Mortgagee (collectively, the “Notes”).

B.            Capitalized terms used herein and not otherwise defined herein have the meanings ascribed to such terms in the Credit Agreement.

C.            Mortgagor’s obligations under the Notes are secured by, among other things, the Mortgage.

D.            Mortgagee is willing to replace the Revolving Credit Note (“Revolving Credit Note”) and extend additional credit to Mortgagor pursuant to an Amended and Restated

Revolving Credit Note of even date hereof (the “Amended and Restated Note”) to permit the Mortgagor to borrow a sum totaling $38,500,000.00. As a condition of the Mortgagee’s agreement to replace the Revolving Credit Note and extend additional credit pursuant to the Amended and Restated Note, Mortgagor agrees to modify the Mortgage accordingly.

E.             The parties hereto desire to amend the Mortgage to incorporate the changes set forth in this First Amendment.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree to amend the Mortgage as of the date hereof as follows:

1.     The Mortgage is hereby amended to secure all Mortgagor’s obligations under the Amended and Restated Note, and the other agreements of the Mortgagor delivered pursuant thereto, including any and all amendments and supplements thereof.

2.     The Mortgage is amended to add the additional principal indebtedness due under the Amended and Restated Note, so that the amended maximum principal indebtedness secured by this Mortgage is $38,500,000. This Amendment secures, inter alia, the obligations which may provide for obligatory future advances, which when made, shall have the same priority as advances made on the date hereof whether or not (i) any advances were made on the date hereof and (ii) any indebtedness is outstanding at the time any advance is made.

3.     The Credit Agreement provides that Mortgagee may, in its sole discretion, in addition to any other authority to make loans and advances to Mortgagor, including protective advances, make additional loans to Mortgagor, make additional credit facilities available to Mortgagor, or renew, extend, or increase any credit facility. No amendment to this Mortgage, as amended by this First Amendment, will be required to the extent the aggregate principal amount outstanding under the Amended and Restated Note (including any amount outstanding under any future loan or credit facility) does not exceed $38,500,000.

4.     Except as modified herein, all of the terms and conditions of the Mortgage remain unchanged and in full force and effect as of the date hereof and are hereby ratified by the Mortgagee and Mortgagor.
