---

6. RATIFICATION OF REPRESENTATIONS AND WARRANTIES. Borrower hereby ratifies, confirms and reaffirms,
all and singular, the terms and disclosures contained in a certain Representations and Warranties dated as of January 9, 2007, between Borrower and Bank (the Representations and Warranties), and acknowledges, confirms and agrees the

corporation, (b) that Borrowers chief executive address is 894 Ross Drive, Sunnyvale, California 94089, and (c) as set forth on Annex A of the Seventh Amendment.

7. AUTHORIZATION TO FILE. Borrower hereby authorizes Bank to file UCC financing statements without notice to Borrower, with all appropriate jurisdictions, as Bank deems appropriate, in order to
further perfect or protect Banks interest in the Collateral, including a notice that any disposition of the Collateral, by either Borrower or any other Person, shall be deemed to violate the rights of Bank under the Code.

8. CONSISTENT CHANGES. The Existing Loan Documents are hereby amended wherever necessary to reflect the changes described above.

9. RATIFICATION OF LOAN DOCUMENTS. Borrower hereby ratifies, confirms, and reaffirms all terms and conditions of all security or other collateral
granted to Bank and confirms that the indebtedness secured thereby includes, without limitation, the Obligations.

10. 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.

11. 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.

12. RIGHT OF SET-OFF. In consideration of Banks agreement to enter into this Loan Modification Agreement, Borrower hereby reaffirms and
hereby grants to Bank, a lien, security interest and right of set off as security for all Obligations to Bank, whether now existing or hereafter arising upon and against all deposits, credits, collateral and property, now or hereafter in the
possession, custody, safekeeping or control of Bank or any entity under the control of Bank (including a Bank subsidiary) or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default, without
demand or notice, Bank may set off the same or any part thereof and apply the same to any liability or obligation of Borrower even though unmatured and regardless of the adequacy of any other collateral securing the loan. ANY AND ALL RIGHTS TO
REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER, ARE HEREBY KNOWINGLY,
VOLUNTARILY AND IRREVOCABLY WAIVED.

13. 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 State of California in any action, suit, or proceeding of any kind against it which arises out of or by reason of this Loan Modification
Agreement. NOTWITHSTANDING THE FOREGOING, BANK SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH BANK DEEMS NECESSARY OR APPROPRIATE IN ORDER TO



---

REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE BANKS RIGHTS AGAINST BORROWER OR ITS PROPERTY.

14. CONFIDENTIALITY. Bank may use confidential information for the development of databases, reporting purposes, and market analysis, so long as such confidential information is aggregated and
anonymized prior to distribution unless otherwise expressly permitted by Borrower. The provisions of the immediately preceding sentence shall survive the termination of the Loan Agreement.

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