 ACKNOWLEDGMENT OF CONTINUING SECURITY INTEREST 

The Undersigned (hereinafter referred to as “Grantor”) hereby acknowledges and agrees that he/she/it has read and is familiar with, and hereby
consents to, all of the terms and conditions of a Fourth Loan Extension Agreement between CATHAY BANK (“Bank”), VERISILICON, INC. (“Company”) and VERISILICON HOLDINGS CO., LTD, formerly known as VERISILICON HOLDINGS (Cayman
Islands) Co., Ltd. (“Parent” and together with Company, the “Borrowers” and each a “Borrower”), dated as of November 30, 2011 and all of the agreements and documents referred to therein, and specifically consent to
the financial accommodations extended and to be extended by Bank to Borrower as set forth therein, and in said agreements and documents. Grantor hereby confirms and agrees that all of the terms and provisions of that certain Security Agreement dated
June 27, 2008 (hereinafter referred to as the “Security Agreement”), are hereby ratified and confirmed, and shall continue in full force and effect as granting a security interest in the described collateral for all obligations of
Borrowers to Bank, however evidenced. 
 Although Bank has informed Grantor of the Fourth Loan Extension Agreement, and Grantor has acknowledged having read
the same and consented to all of the terms and conditions thereof, Grantor understands and agrees that Bank has no duty under any agreement with Borrowers, the Security Agreement or any agreement with the Grantor to so notify the Grantor or to seek
such an acknowledgment and consent, and nothing contained herein is intended to, or shall create such a duty as to any advances or transactions hereafter. 

ARBITRATION. Bank and Grantor agree that all disputes, claims and controversies between them, whether individual, joint, or class in nature, arising
from this Acknowledgement of Continuing Security Interest and the Security Agreement, including without limitation contract and tort disputes, shall be arbitrated pursuant to the rules of the American Arbitration Association (“AAA”) in
accordance with its Commercial Arbitration Rules and Supplemental Procedures for Financial Services Disputes, upon request of either party. No act to take or dispose of any collateral securing this Acknowledgement of Continuing Security Interest and
the Security Agreement shall constitute a waiver of this arbitration agreement or be prohibited by this arbitration agreement. This includes, without limitation, obtaining injunctive relief or a temporary restraining order; invoking a power of sale
under any deed of trust or mortgage; obtaining a writ of attachment or imposition of a receiver; or exercising any rights relating to personal property, including taking or disposing of such property with or without judicial process pursuant to

act of any party. Bank and Grantor agree that in the event of an action for judicial foreclosure pursuant to California Code of Civil Procedure Section 726, or any similar provision in any

appeal from a judgment after trial by court. Nothing in this Acknowledgement of Continuing Security Interest and the Security Agreement shall preclude any party from seeking equitable relief from a court of competent jurisdiction. The statute of
limitations, estoppel, waiver, laches, and similar doctrines which would otherwise be applicable in an action brought by a party shall be applicable in any arbitration proceeding, and the commencement of an arbitration proceeding shall be deemed the
commencement of an action for these purposes.

and, if necessary, a third list shall be circulated and exhausted before the AAA is empowered to make the appointment. 
 The Federal Arbitration Act
shall apply to the construction, interpretation, and enforcement of this arbitration provision 
 By these provisions, each party waives the
constitutional right to a jury trial to resolve a dispute arising under this agreement.

 ARBITRATION. Bank and Guarantor agree that all disputes, claims and controversies between them, whether individual, joint, or class
in nature, arising from this Reaffirmation of Guaranty and the Guaranty, including without limitation contract and tort disputes, shall be arbitrated pursuant to the rules of the American Arbitration Association (“AAA”) in accordance with
its Commercial Arbitration Rules and Supplemental Procedures for Financial Services Disputes, upon request of either party. No act to take or dispose of any collateral securing this Reaffirmation of Guaranty and the Guaranty shall constitute a
waiver of this arbitration agreement or be prohibited by this arbitration agreement. This includes, without limitation, obtaining injunctive relief or a temporary restraining order; invoking a power of sale under any deed of trust or mortgage;
obtaining a writ of attachment or imposition of a receiver; or exercising any rights relating to personal property, including taking or disposing of such property with or without judicial process pursuant to article 9 of the Uniform Commercial Code.
Any disputes, claims, or controversies concerning the lawfulness or reasonableness of any act, or exercise of any right, concerning any collateral securing this Reaffirmation of Guaranty and the Guaranty, including without limitation, any claim to
rescind, reform, or otherwise modify any agreement relating to the collateral securing this Reaffirmation of Guaranty and the Guaranty shall also be arbitrated, provided however that no arbitrator shall have the right or the power to enjoin or
restrain any act of any party. Bank and Guarantor agree that in the event of an action for judicial foreclosure pursuant to California Code of Civil

Procedure Section 726, or any similar provision in any other State, the commencement of such an action will not constitute a waiver of the right to arbitrate and the court shall refer to
arbitration as much of such action, including counterclaims, as lawfully may be referred to arbitration. Judgment upon any award rendered by any arbitrator may be entered in any court having jurisdiction. The arbitrators shall not have power to make
an award of $1.0 million or more against any party to an arbitration unless it is in the form of a statement of decision as described in California Code of Civil Procedure Section 632, and the parties specifically reserve the right, upon a
petition to vacate, to have any such award reviewed and vacated upon the same grounds as would result in reversal on appeal from, a judgment after trial by court. Nothing in this Reaffirmation of Guaranty and the Guaranty shall preclude any party
from seeking equitable relief from a court of competent jurisdiction. The statute of limitations, estoppel, waiver, laches, and similar doctrines which would otherwise be applicable in an action brought by a party shall be applicable in any
arbitration proceeding, and the commencement of an arbitration proceeding shall be deemed the commencement of an action for these purposes. 
 To the
extent not provided by this agreement, including the Rules incorporated herein, arbitration hereunder shall be governed by California arbitration law. Arbitration shall be conducted in California, in English and, unless otherwise agreed to by the
parties with respect to a particular dispute, shall be heard by a panel of three arbitrators. The arbitrators in any arbitration shall be experienced in the areas of law raised by the subject matter of the dispute. Lists of prospective arbitrators
shall include retired judges. Notwithstanding the AAA rules, (a) any party may strike from a list of prospective arbitrators any individual who is regarded by that party as not appropriate for the dispute; and (b), if the arbitrator appointment
cannot be made from the initial list of prospective arbitrators circulated by the AAA, a second and, if necessary, a third list shall be circulated and exhausted before the AAA is empowered to make the appointment. 

The Federal Arbitration Act shall apply to the construction, interpretation, and enforcement of this arbitration provision 

By these provisions, each party waives the constitutional right to a jury trial to resolve a dispute arising under this agreement.
