Agent and Lenders hereby consent to the issuance of the New Subordinated Note by Parametric and agree that the obligations of Borrowers under the New Subordinated Note are Subordinated Debt so long as the New Subordinated Note is in form and substance previously delivered to and approved by Agent. In connection with such consent, Agent, Lenders and Borrowers hereby agree to amend the definition of TBC Note to read as follows:

The consent set forth above shall be effective only in this specific instance and for the specific purpose for which it is given, and this consent shall not entitle Borrowers to any other or further consent or waiver in any similar or other circumstances. The consent set forth above shall be limited precisely as written and shall not be deemed to (a) be a waiver or modification of any other term or condition of the Loan Agreement or any other Loan Document or (b) prejudice any right or remedy which Agent or any Lender may now have or may have in the future under or in connection with the Loan Agreement or any Loan Document.
