1.             In order to extend the maturity date set forth in the Loan Agreement, Section 1.3(a) is hereby amended by deleting such section in its entirety and by substituting the following section therefor:

“1.3(a)                    The Borrower will make monthly interest and principal payments under the Loan as set forth in the Note.  The Loan shall mature on December 15, 2014 upon which date the entire remaining balance of the Loan, if any, shall be immediately due and payable.”

The above-referenced documents, together with this Agreement, shall be referred to herein as the “Modification Documents”.  The definition of Loan Documents in this Agreement shall include the Modification Documents.

3.             Borrower hereby represents and warrants that (i)  its representations and warranties set forth in the Loan Agreement are true on and as of the date hereof as if made on such date (except to the extent that the same expressly relate to an earlier date or are affected by the consummation of transactions permitted hereby or by the Agreement); (ii) it is in compliance in all material respects with all of the terms and provisions set forth in the Loan Agreement on its part to be observed or performed; (iii) after giving effect to any extension of credit to be made on the date hereof, no Event of Default (as defined in the Loan Agreement) or event which, with the giving of notice or expiration of any applicable grace period or both would constitute an Event of Default, has occurred and is continuing; (iv) since the date of the financial statements most recently provided to Lender by Borrower, there has occurred no material adverse change in the assets or liabilities or the financial or other condition of Borrower; (v) it has full power to execute, deliver and perform its obligations under the Modification Documents and the execution, delivery and performance of the Modification Documents has been authorized and directed by the appropriate parties; (vi) this Agreement constitutes the legal, valid and binding obligation of Borrower, enforceable in accordance with its terms; (vii) the execution, delivery and performance hereof will not violate any provision of any existing law or regulation applicable to Borrower or other governing documents or of any order or decree of any court, arbitrator or governmental authority or of any contractual undertaking to which it is a party or by which it may be bound; and (viii) no consents, licenses, approvals or authorizations of, exemptions by or registrations or filings with, any governmental authority are required with respect to this Agreement.

4.             If Borrower fails to comply with all the terms and conditions of this Agreement within applicable cure periods, if any, it shall constitute a default under this Agreement and under the other Loan Documents for which default Lender shall be entitled to pursue any or all of its rights and remedies under the Loan Documents.

5.             No other changes shall be made to the Loan Agreement and Borrower reaffirms its obligations under the Loan Documents in their entirety.  This Agreement is not intended to extinguish or affect any of the debt evidenced by the Note, except as set forth herein, or to otherwise modify any of the obligations under any of the Loan Documents.  Borrower hereby reaffirms that Borrower remains indebted to Lender without defense, counterclaim or offset.

6.             This Agreement is made in The Commonwealth of Massachusetts and shall be construed in accordance with its laws.  If any provision hereof is in conflict with any statute or rule of law of The Commonwealth of Massachusetts or any other statute or rule of law of any other applicable jurisdiction or is otherwise unenforceable, such provisions shall be deemed null and void only to the extent of such conflict or unenforceability and shall be deemed separate from and shall not invalidate any other provision of this Agreement.

7.             This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, and no other parties shall be a beneficiary hereunder.  Neither this Agreement nor any of the provisions hereof can be changed, waived, discharged or terminated except by an instrument in writing signed by the party against whom enforcement of the change, waiver, discharge or termination is sought.

8.             This Agreement and any amendment hereof may be executed by the different parties hereto on any number of separate counterparts, each of which, when so executed and delivered, shall be an original, and all such counterparts shall together constitute one and the same instrument.
