pursuant to the Existing Loan Documents, applicable law or otherwise.

connection herewith and Borrower’s performance of all of the transactions contemplated hereby (but only to the extent required since last delivered to Bank), and (iii) an incumbency certificate giving the name and bearing a specimen

	 	G.	a legal opinion of Borrower’s counsel as to authority and enforceability, dated as of the date hereof; and 

 

	 	H.	such other documents as Bank may reasonably request.

hereof. Borrower shall also reimburse Bank for all legal fees and expenses incurred in connection with this amendment to the Existing Loan Documents. 
 7. RATIFICATION OF NEGATIVE PLEDGE. Borrower hereby ratifies, confirms and reaffirms, all and singular, the terms and conditions of a certain negative pledge arrangement with respect to
Borrower’s intellectual property, between Borrower and Bank, and Borrower acknowledges, confirms and agrees that said negative pledge arrangement remains in full force and effect. 
 8. ADDITIONAL COVENANTS: RATIFICATION OF PERFECTION CERTIFICATE. Borrower shall not, without providing the Bank with thirty (30) days prior written notice: (i) relocate its principal
executive office or add any new offices or business locations or keep any Collateral, in excess of Ten Thousand Dollars ($10,000.00) in any additional locations, or (ii) change its jurisdiction of organization, or (iii) change its
organizational structure or type, (iv) change its legal name, or (v) change any organizational number (if any) assigned by its jurisdiction of organization. In addition, the Borrower hereby certifies that no Collateral in excess of Ten
Thousand Dollars ($10,000.00) is in the possession of any third party bailee (such as at a warehouse). In the event that Borrower, after the date hereof, intends to store or otherwise deliver the Collateral in excess of Ten Thousand Dollars

 9. 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 the
Borrower or any other Person, shall be deemed to violate the rights of the Bank under the Code. 
 10. CONSISTENT CHANGES. The Existing
Loan Documents are hereby amended wherever necessary to reflect the changes described above. 
 11. RATIFICATION OF LOAN DOCUMENTS.
Borrower hereby ratifies, confirms, and reaffirms all terms and conditions of all security or other collateral granted to the Bank, and confirms that the indebtedness secured thereby includes, without limitation, the Obligations. 

12. 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. 
 13. 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. 

 14. 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 Silicon Valley 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. 
 15. 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. 
 16. JURISDICTION/VENUE. Section 11 of the
Loan Agreement is hereby incorporated by reference in its entirety. 
 17. COUNTERSIGNATURE. This Loan Modification Agreement shall
become effective only when it shall have been executed by Borrower and Bank.

 Recitals: 
 A. Bank and Creditor have entered into that certain
Subordination Agreement, dated as of October 31, 2011 (as the same has been or may be amended, restated, supplemented or otherwise modified from time to time, the “Subordination Agreement”; capitalized terms used but not

 B.
Creditor has extended loans or other credit accommodations to Borrower, and/or may extend loans or other credit accommodations to Borrower from time to time. 
 C. The Borrower has requested and Bank has agreed, subject to the terms and conditions of a certain Third Loan Modification and Waiver Agreement, dated as of the date hereof (the “Third Loan

further amended by a certain Second Loan Modification Agreement, dated as of March 8, 2011 (as amended by the Third Loan Modification Agreement, and as may be further amended the “Loan Agreement”). All obligations of the
Borrower to the Bank are secured by the Collateral (as such term is defined in the Loan Agreement). 
 D. The Borrower, the
Creditor and Bank desire to reaffirm the continuing effectiveness of the Subordination Agreement, all as provided for herein. 

Now, therefore, in consideration of the mutual promises contained herein, the parties hereby agree as follows: 

1. Incorporation of Recitals. Bank and Creditor hereby represent and warrant each to the other that the foregoing Recitals
are: (a) true and accurate; and (b) an integral part of the Acknowledgment. Bank and Creditor hereby agree that all of the Recitals herein are hereby incorporated into the Subordination Agreement and made a part thereof. As used herein,
references to this “Agreement” shall mean the Subordination Agreement as acknowledged and reaffirmed hereby. 

2. Acknowledgement/Reaffirmation of Subordination Agreement/Waiver of Existing Defaults. Creditor hereby (i) expressly
ratifies and reaffirms the continued subordination of the Subordinated Debt to the Senior Debt in accordance with, and its liabilities, obligations and agreements under, the terms of the Subordination Agreement, (ii) acknowledges and agrees

transmission also shall deliver an original executed counterpart of this Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Acknowledgment. The foregoing
