As a result of the increase, the quarterly principal payments due under the Loan Agreement increased from $750,000 to $937,500, and the weighted-average interest rate changed to 3.92% as of May 31, 2011.

The Barton Note is due and payable in June 2011. Pursuant to the terms of the Purchase Agreement, until the expiration of the put-options, no payment will be made on the Barton Note and payment of the amounts owing under the Barton Note will be subordinate to any amounts owing Prime upon the exercise of a put option.</font></font></font></div>
