|Principal Amount: $1,950,212.96 |  | Initial Rate: 8.250% |  | Date of Agreement: March 30, 2007

DESCRIPTION OF EXISTING INDEBTEDNESS. Obligor No.: 100333631.

Obligation No.: 50001.

Original (a) promissory note from Borrower to
Lender dated May 10, 2006 in the original principal amount of $1,835,071.55 and (b) promissory note from Borrower to Lender dated October 24, 2004 In the original principal amount of $400,000.

Effective March 30, 2007, Lender hereby (a) terminates all agreements with Borrower other than the agreements entered into on the date hereof and the Open-End
Mortgage dated May 10, 2006 in the principal amount of $1,835,071.55 (collectively, the 2007 Documents), (b) releases all of its security interests and liens on the assets of Borrower other than its lien on the Borrowers real
property and (c) acknowledges that all liabilities of Borrower to Lender have been paid and performed in full other than those evidenced by the 2007 Documents.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms of the original obligation or obligations, including all agreements evidenced or securing the obligation(s), remain unchanged and in
full force and effect. Consent by Lender to this Agreement does not waive Lenders right to strict performance of the obligation(s) as changed, nor obligate Lender to make any future change in terms. Nothing in this Agreement will constitute a
satisfaction of the obligation(s). It is the intention of Lender to retain as liable parties all makers and endorsers of the original obligation(s), including accommodation parties, unless a party is expressly released by Lender in writing. Any
maker or endorser, including accommodation makers, will not be released by virtue of this Agreement. If any person who signed the original obligation does not sign this Agreement below, then all persons signing below acknowledge that this Agreement
is given conditionally, based on the representation to Lender that the non-signing party consents to the changes and provisions of this Agreement or otherwise will not be released by it. This waiver applies not only to any initial extension,
modification or release, but also to all such subsequent actions.

CONFESSION OF JUDGEMENT. Borrower hereby irrevocably authorizes and empowers any
attorney-at-law, including an attorney hired by Lender, to appear in any court of record and to confess judgment against Borrower for the unpaid amount of this Note as evidenced by an affidavit signed by an officer of Lender setting forth the amount
due, attorneys fees plus costs of suit, and to release all errors, and waive all rights of appeal. If a copy of this Note, verified by an affidavit, shall have bean filed in the proceeding, it will not be necessary to file the original as a
warrant of the attorney. Borrower waives the right to any stay of execution and the benefit of all exemption laws now hereafter in effect. No single exercise of the foregoing warrant and power to confess judgment will be deemed to exhaust the power,
whether or not any such exercise shall be held by any court to be invalid, voidable, or void; but the power will continue undiminished and may be exercised from time to time as Lender may elect until all amounts owing on this Note have been paid in
full. Borrower waives any conflict of interest that an attorney hired by Lender may have in acting on behalf of Borrower in confessing judgment against Borrower while such attorney is retained by Lender. Borrower expressly consents to such attorney
acting for Borrower in confessing judgment and agrees that such attorney may receive a legal fee or other compensation from Lender.
