Hereinafter, the Loan Agreement, together with all other documents executed in connection therewith evidencing, securing or otherwise relating to the Obligations shall
be referred to as the Existing Loan Documents.

3. DESCRIPTION OF CHANGE IN TERMS.

A. Modifications to Loan Agreement.

Section 6.9(b) of the Loan Agreement is hereby deleted in its entirety and replaced with the following:

(b) Maximum
Loss/Profitability. Borrower shall not permit its Net Income in any three month period to be less than (i) ($200,000), from the Effective Date through May 31, 2006, (ii) ($50,000), from June 1, 2006 through July 31, 2006,

---

8. NO DEFENSES OF BORROWER. Borrower hereby acknowledges and agrees that Borrower has no offsets, defenses,
claims, or counterclaims against Bank with respect to the Obligations, or otherwise, and that if Borrower now has, or ever did have, any offsets, defenses, claims, or counterclaims against Bank, whether known or unknown, at law or in equity, all of
them are hereby expressly WAIVED and Borrower hereby RELEASES Bank from any liability thereunder.

9. CONTINUING VALIDITY. Borrower understands and
agrees that in modifying the existing Obligations, Bank is relying upon Borrowers representations, warranties, and agreements, as set forth in the Existing Loan Documents. Except as expressly modified pursuant to this Loan Modification
Agreement, the terms of the Existing Loan Documents remain unchanged and in full force and effect. Banks agreement to modifications to the existing Obligations pursuant to this Loan Modification Agreement in no way shall obligate Bank to make
any future modifications to the Obligations. Nothing in this Loan Modification Agreement shall constitute a satisfaction of the Obligations. It is the intention of Bank and Borrower to retain as liable parties all makers of Existing Loan Documents,
unless the party is expressly released by Bank in writing. No maker will be released by virtue of this Loan Modification Agreement.

10.
JURISDICTION/VENUE. Borrower accepts for itself and in connection with its properties, unconditionally, the exclusive jurisdiction of any state or federal court of competent jurisdiction in the Commonwealth of Massachusetts in any action,
suit, or proceeding of any kind against it which arises out of or by reason of this Loan Modification Agreement; provided, however, that if for any reason Bank cannot avail itself of the courts of the Commonwealth of Massachusetts, then venue shall
lie in Santa Clara County, California. NOTWITHSTANDING THE FOREGOING, THE BANK SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST THE BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH THE BANK DEEMS NECESSARY OR
APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE THE BANKS RIGHTS AGAINST THE BORROWER OR ITS PROPERTY.

11.
COUNTERSIGNATURE. This Loan Modification Agreement shall become effective only when it shall have been executed by Borrower and Bank.

This Loan Modification Agreement is executed as a sealed instrument under the laws of the Commonwealth of Massachusetts as of the date first written above.
