this Agreement and each other of the Loan Documents. 
 SECTION 7.8 SEVERABILITY OF PROVISIONS. If any provision of this Agreement shall be
prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity without invalidating the remainder of such provision or any remaining provisions of this Agreement. 

SECTION 7.9 COUNTERPARTS. This Agreement may be executed in any number of counterparts, each of which when executed and delivered shall be deemed to
be an original, and all of which when taken together shall constitute one and the same Agreement. 
 SECTION 7.10 GOVERNING LAW. This
Agreement shall be governed by and construed in accordance with the laws of the State of California. 
 SECTION 7.11 ARBITRATION. 

(a) Arbitration. The parties hereto agree, upon demand by any party, to submit to binding arbitration all claims, disputes and controversies
between or among them (and their respective employees, officers, directors, attorneys, and other agents), whether in tort, contract or otherwise in any way arising out of or relating to (i) any credit subject hereto, or any of the Loan
Documents, and their negotiation, execution, collateralization, administration, repayment, modification, extension, substitution, formation, inducement, enforcement, default or termination; or (ii) requests for additional credit. 
 (b) Governing Rules. Any arbitration proceeding will (i) proceed in a location in California selected by the American Arbitration Association
(“AAA”); (ii) be governed by the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the documents between the parties; and (iii) be conducted by the AAA,
or such other administrator as the parties shall mutually agree upon, in accordance with the AAA’s commercial dispute resolution procedures, unless the claim or counterclaim is at least $1,000,000.00 exclusive of claimed interest, arbitration
fees and costs in which case the arbitration shall be conducted in accordance with the AAA’s optional procedures for large, complex commercial disputes (the commercial dispute resolution procedures or the optional procedures for large, complex
commercial disputes to be referred to herein, as applicable, as the “Rules”). If there is any inconsistency between the terms hereof and the Rules, the terms and procedures set forth herein shall control. Any party who fails or refuses to
submit to arbitration following a demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any dispute. Nothing contained herein shall be deemed to be a waiver by any party that is a bank
of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law.

SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24b-2 OF
THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 

 (c) No Waiver of Provisional Remedies, Self-Help and Foreclosure. The arbitration requirement does
not limit the right of any party to (i) foreclose against real or personal property collateral; (ii) exercise self-help remedies relating to collateral or proceeds of collateral such as setoff or repossession; or (iii) obtain
provisional or ancillary remedies such as replevin, injunctive relief, attachment or the appointment of a receiver, before during or after the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the right or
obligation of any party to submit any dispute to arbitration or reference hereunder, including those arising from the exercise of the actions detailed in sections (i), (ii) and (iii) of this paragraph. 
 (d) Arbitrator Qualifications and Powers. Any arbitration proceeding in which the amount in controversy is $5,000,000.00 or less will be decided
by a single arbitrator selected according to the Rules, and who shall not render an award of greater than $5,000,000.00. Any dispute in which the amount in controversy exceeds $5,000,000.00 shall be decided by majority vote of a panel of three
arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations. The arbitrator will be a neutral attorney licensed in the State of California or a neutral retired judge of the state or federal
judiciary of California, in either case with a minimum of ten years experience in the substantive law applicable to the subject matter of the dispute to be arbitrated. The arbitrator will determine whether or not an issue is arbitrable and will give
effect to the statutes of limitation in determining any claim. In any arbitration proceeding the arbitrator will decide (by documents only or with a hearing at the arbitrator’s discretion) any pre-hearing motions which are similar to motions to
dismiss for failure to state a claim or motions for summary adjudication. The arbitrator shall resolve all disputes in accordance with the substantive law of California and may grant any remedy or relief that a court of such state could order or
grant within the scope hereof and such ancillary relief as is necessary to make effective any award. The arbitrator shall also have the power to award recovery of all costs and fees, to impose sanctions and to take such other action as the
arbitrator deems necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the California Rules of Civil Procedure or other applicable law. Judgment upon the award rendered by the arbitrator may be entered in any
court having jurisdiction. The institution and maintenance of an action for judicial relief or pursuit of a provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff, to submit the controversy
or claim to arbitration if any other party contests such action for judicial relief. 
 (e) Discovery. In any arbitration proceeding,
discovery will be permitted in accordance with the Rules. All discovery shall be expressly limited to matters directly relevant to the dispute being arbitrated and must be completed no later than 20 days before the hearing date. Any requests for an
extension of the discovery periods, or any discovery disputes, will be subject to final determination by the arbitrator upon a showing that the request for discovery is essential for the party’s presentation and that no alternative means for
obtaining information is available. 
 (f) Class Proceedings and Consolidations. No party hereto shall be entitled to join or
consolidate disputes by or against others in any arbitration, except parties who have executed any Loan Document, or to include in any arbitration any dispute as a representative or member of a class, or to act in any arbitration in the interest of
the general public or in a private attorney general capacity.

THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 

 (g) Payment Of Arbitration Costs And Fees. The arbitrator shall award all costs and expenses of
the arbitration proceeding. 
 (h) Real Property Collateral; Judicial Reference. Notwithstanding anything herein to the contrary, no
dispute shall be submitted to arbitration if the dispute concerns indebtedness secured directly or indirectly, in whole or in part, by any real property unless (i) the holder of the mortgage, lien or security interest specifically elects in
writing to proceed with the arbitration, or (ii) all parties to the arbitration waive any rights or benefits that might accrue to them by virtue of the single action rule statute of California, thereby agreeing that all indebtedness and
obligations of the parties, and all mortgages, liens and security interests securing such indebtedness and obligations, shall remain fully valid and enforceable. If any such dispute is not submitted to arbitration, the dispute shall be referred to a
referee in accordance with California Code of Civil Procedure Section 638 et seq., and this general reference agreement is intended to be specifically enforceable in accordance with said Section 638. A referee with the qualifications
required herein for arbitrators shall be selected pursuant to the AAA’s selection procedures. Judgment upon the decision rendered by a referee shall be entered in the court in which such proceeding was commenced in accordance with California
Code of Civil Procedure Sections 644 and 645. 
 (i) Miscellaneous. To the maximum extent practicable, the AAA, the arbitrators and
the parties shall take all action required to conclude any arbitration proceeding within 180 days of the filing of the dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results
thereof, except for disclosures of information by a party required in the ordinary course of its business or by applicable law or regulation. If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the
arbitration provision most directly related to the Loan Documents or the subject matter of the dispute shall control. This arbitration provision shall survive termination, amendment or expiration of any of the Loan Documents or any relationship
between the parties. 
 (j) Small Claims Court. Notwithstanding anything herein to the contrary, each party retains the right to
pursue in Small Claims Court any dispute within that court’s jurisdiction. Further, this arbitration provision shall apply only to disputes in which either party seeks to recover an amount of money (excluding attorneys’ fees and costs)
that exceeds the jurisdictional limit of the Small Claims Court. 
 SECTION 7.12 CONFIDENTIALITY. In handling any confidential information,
Bank shall exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (a) to Bank’s Subsidiaries or Affiliates; (b) to prospective transferees or purchasers of
any interest in the Credit Extensions (provided, however, Bank shall use commercially reasonable efforts to obtain such prospective transferee’s or purchaser’s agreement to the terms of this provision); (c) as required by law,
regulation, subpoena, or other order; (d) to Bank’s regulators or as otherwise required in connection with Bank’s examination or audit; (e) as Bank considers appropriate in exercising remedies under the Loan Documents; and
(f) to third-party service providers of Bank so long as

such service providers have executed a confidentiality agreement with Bank with terms no less restrictive than those contained herein. Confidential
information does not include information that either: (i) is in the public domain or in Bank’s possession when disclosed to Bank, or becomes part of the public domain after disclosure to Bank; or (ii) is disclosed to Bank by a third
party, if Bank does not know that the third party is prohibited from disclosing the information.

 Exhibit A 
 Cerus Corporation 
 Investment Policy 
  

	I.	Purpose & Objectives 

 The purpose of the Company’s
investment policy is to establish guidelines for the investment of surplus cash. “Surplus cash” is cash and marketable securities held in corporate accounts not immediately required for operations, working capital, capital investment, debt
repayment or other outstanding near-term financial obligations. 
 The principal objectives of the policy are to: 1) conserve capital and 2) maintain
appropriate liquidity, pending anticipated application of cash in business operations. Beyond the policy’s two principal objectives, the policy objectives are to: 
 A. Diversify investments to minimize the risk from inappropriate concentrations of investments with any one entity; 
 B.
Deliver returns consistent with benchmark indexes for similar investments; and 
 C. Provide fiduciary control of cash and investments by individuals
approved by the Company’s Board of Directors. 
  

	II.	Investment Guidelines 

 Surplus cash is to be invested in keeping with the
objectives set forth above. The investment of surplus cash requires that: 
 A. At least [ * ] must be invested in a highly liquid money market fund, such
that cash is immediately available to the Company each business day until 1:30 p.m. Eastern time; and 
 B. The remainder of the funds is to be invested,
consistent with anticipated cash needs, in securities with maturities no longer than thirty-six (36) months. As a general rule, investments are to be held to maturity. However, repositioning of these securities before their maturity, generating
small gains or losses (with such gains or losses defined as being less than 50% of the current quarter’s net investment income in the aggregate), is permitted in order to maximize return while conserving capital and maintaining liquidity.
Repositioning of securities beyond this discretionary level must be pre-approved by Company’s management for fiduciary control purposes.

SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24b-2 OF
THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 

	III.	Investment Restrictions 

 Investments of surplus cash shall be made in the
context of the following investment guidelines: 
 Eligible Investments include only: 
 A. Direct obligations of the U.S. Treasury, including bills, notes, and bonds, including putable, callable and floating-rate obligations; 
 B. Obligations issued or guaranteed by agencies or sponsored entities of the U.S. government (e.g. Federal Farm Credit Bank (FFCB), Federal Home Loan Bank (FHLB), Federal Home Loan Mortgage Corporation (FHLMC), and
Federal National Mortgage Association (FNMA)), including putable, callable and floating-rate obligations; 
 C. Obligations of commercial banks with a
minimum of $10 billion in total assets, including but not limited to negotiable certificates of deposit (domestic, Yankee & Eurodollar CDs), banker’s acceptances, bank time deposits (domestic or Eurodollar), and deposits placed with
offshore branches of approved banks (Eurodollar, CDs & time deposits); 
 D. Corporate debt instruments, including commercial paper and other
short-term, unsecured promissory notes issued by domestic and foreign corporations or financial institutions, including but not limited to medium-term notes, master notes, deposit notes, 144(a) securities, Eurodollar notes, and Yankee notes and
bonds, and Floating rate notes. 
 E. Money market auction rate securities with appropriate counter parties, credit, and underlying assets, including
municipal auction rate securities, select auction variable rate securities, tax-exempt preferred stock, money market preferred stock and taxable auction rate securities; 
 F. Tri-party repurchase agreements purchased from one of the top 25 US banks or one of the primary dealers regulated by the Federal Reserve, collateralized at a minimum of 102% with U.S. Treasury securities or U.S.
government agency securities; 
 G. U.S. and dollar-denominated international corporate debt of all types, provided the issuer meets credit rating and
marketability guidelines; 
 H. Direct obligations of or obligations fully guaranteed by a state, territory, municipality, or a possession of the U.S., or
any political subdivision of any of the foregoing, or of the District of Columbia as well as obligations of any county or other local governmental body within the U.S.; 
 I. Mortgage backed securities, mortgage pass-throughs, and CMOs backed by the U.S. government or agency thereof and mortgage pass-throughs rated at least Aaa by Moody’s or AAA by Standard & Poor’s
are eligible investments. CMOs must be guaranteed as to the full principal and interest. Further, eligible securities are those CMO tranches whose relative position is sufficiently high as to meet the CMO’s cash flow schedule when prepayments
decline and less cash is available for distribution. All eligible CMO tranches must be structured to have a projected stable average life over a wide range of projected interest rates and prepayment speeds. Eligible CMOs must have a weighted average
life (WAL) of three (3) years or less. Only securities that are appropriate for a short-duration investment portfolio and are consistent with Company’s stated objectives of safety of principal and liquidity may be selected; and

IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED AND FILED
SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24b-2 OF
THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 

 J. Money market and mutual funds in which shares of the fund management company are registered under the Investment
Company Act of 1940, as amended. The investments of that company must comply with the SEC regulations under rule 2a-7 or be regulated and advised by a Registered Investment Advisor under rule 3c-7. Funds must maintain a constant net asset value,
offer daily liquidity, and have an average weighted maturity that does not exceed 120 days. Investments must be in acceptable securities as stated within this policy and with a nationally recognized fund manager with over five years of easily
tracked performance. 
 K. Asset-Backed Securities – Fixed and floating rates. Maximum 3 year weighted average life. 
 Derivative instruments are ineligible as investments, including all investments where the value is based on an underlying variable causing the coupon and/or the maturity
value to be unknown for the life of the security. Prohibited securities also include, but are not limited to, inverse floaters, inverse IOs, residuals, super POs, tiered indexed bonds, and two-tiered indexed bonds. Specifically prohibited are
floating rate securities with embedded interest rate caps, floors, collars, inverse interest rate relationships, leverage floaters, or indices not directly correlated with money market interest rate movements. Short sales, margin purchases, futures,
options (purchases or sales), and foreign currency purchases are not permitted for the investment portfolio. Direct securities lending by the Company or its external managers is not permitted. 
 Callable and putable securities are permissible. 
  

	IV.	Maturities 

 The maximum maturity, demand feature, or average life of
individual securities in the portfolio may not exceed thirty-six (36) months. 
 The maximum average maturity of the Company’s total portfolio may
not exceed eighteen (18) months. 
 For securities that have put dates or reset dates, the put date or reset date will be used, instead of the final
maturity date, for maturity guideline purposes. 
  

	V.	Concentration Limits/Restrictions 

 There is no limit to the percentage of
the portfolio that may be maintained in securities issued by the U.S. Treasury. However, at the time of purchase no more than 50% of the portfolio may be invested in any single Federal agency security or government sponsored enterprise (GSE).

 No one issue, issuer or group of issuers from the same holding company is to exceed 5% or $5,000,000, whichever is greater, of the portfolio at time of
purchase. Except for strategic investments explicitly approved by the Company’s Board of Directors, no investment will be permitted in common stocks, preferred stocks, options on equities (put or calls), commodities, securities not denominated
in U.S. dollars, futures or mutual funds, whose underlying securities are ineligible investments according to this investment policy. 
  

	VI.	Investment Performance 

 The company shall review the performance of
advisors retained to implement this policy on at least a quarterly basis. Advisors will issue a quarterly investment performance analysis using 

  

 [ * ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED
IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED AND FILED
SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24b-2 OF
THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 

 
AIMR Performance Presentation Standards. Performance will be benchmarked against the Merrill Lynch 6-month Treasury Bill Index, the Salomon 90-day Treasury
Bill Index and/or the Lipper Institutional Money Market Fund Index, as appropriate. A quarterly meeting will be held to review performance and any updated liquidity needs with the individual responsible for fiduciary controls appointed by the
Company’s Board of Directors. Advisors must submit a statement of compliance to this policy on a quarterly basis. 
  

	VII.	Credit Quality 

 All investments made under this policy shall be in
securities where, at the time of the investment, the obligor must be rated at or above the short and long-term rating categories below by at least two of the Nationally Recognized Statistical Rating Organizations (NRSRO’s): 
  

					
	  	  	Short-term	  	Long-term
	 Standard & Poors
	  	A-1	  	A-
	 Moody’s Investor Service
	  	P-1	  	A-3
	 Fitch Ratings
	  	F-1	  	A-

 Individual investments which fall to a rating of BBB (or equivalent) may continue to be held within the investment
portfolio. However, such investments will only be held with a bias to liquidate the position in orderly fashion over the short-term, unless underlying fundamentals suggest that the risk of holding to maturity is negligible and that the rating is
highly unlikely to fall further (i.e. to or below BB or equivalent). Advisors must notify the Company as soon as practicable (same day) if the rating on an investment falls from A to BBB (or equivalent). If the rating on an investment within the
portfolio falls to or below BB (or equivalent), the investment must be liquidated immediately. 
  

	VIII.	Marketability 

 All securities purchased under this policy shall be made
through investment banking and brokerage firms of high quality and reputation, with a history of making markets in securities suitable for investment under this policy. In the event that securities are sold before their maturity, the securities must
be easily remarketed. The advisors must demonstrate that all buy and sell transactions made under this policy achieve best execution available through broker dealers. 
  

	IX.	Trading Guidelines 

 Normal investing practice is to reinvest the funds on
the day a security matures in order to minimize lost yield. However, pending redeployment in higher yielding investments, uninvested funds may be swept into money market funds. A daily transaction log is to be maintained by the advisors and
available for review at any time. A monthly report must be issued to the Company on a timely basis by each manager, in which details are presented for all transactions executed in the investment account during the preceding month. 
  

	X.	Custody of Assets 

 Assets are to be held in a segregated bank custody
account in the name of Cerus Corporation, with separate fiduciary account documents executed by the bank. Assets shall not be co-mingled nor held by any investment manager or securities dealer.

THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 

	XI.	Fiduciary Discretion 

 The Company’s Chief Financial Officer, his/her
authorized employees, and/or other individuals appointed by the Board are responsible for securing and managing investments and cash for operations. These individuals have full discretion to invest any excess capital subject to strict adherence to
this investment policy. The investment policy shall be reviewed periodically with the Board of Directors and revisions made consistent with objectives set forth herein.

 EXHIBIT 10.37 
 SECURITY AGREEMENT 
 1. GRANT OF SECURITY INTEREST. For valuable consideration, the undersigned CERUS CORPORATION, a Delaware corporation (“Debtor”), hereby grants
and transfers to WELLS FARGO BANK, NATIONAL ASSOCIATION (“Bank”) a continuing security interest in all of the property of Debtor described as follows (collectively, the “Collateral”): 
 (a) all accounts, deposit accounts, contract rights, chattel paper (whether electronic or tangible), instruments, promissory notes,
documents, general intangibles (excluding Intellectual Property), payment intangibles, commercial tort claims, securities and all other investment property, supporting obligations and financial assets, letter of credit rights, health-care insurance
receivables and other rights to payment of every kind now existing or at any time hereafter arising, wherever located; 
 (b)
all inventory, goods held for sale or lease or to be furnished under contracts for service, or goods so leased or furnished, raw materials, component parts, work in process and other materials used or consumed in Debtor’s business, now or at
any time hereafter owned or acquired by Debtor, wherever located, and all products thereof, whether in the possession of Debtor, any warehousemen, any bailee or any other Person, or in process of delivery, and whether located at Debtor’s places
of business or elsewhere; 
 (c) all warehouse receipts, bills of sale, bills of lading and other documents of every kind
(whether or not negotiable) in which Debtor now has or at any time hereafter acquires any interest, and all additions and accessions thereto, whether in the possession or custody of Debtor, any bailee or any other Person for any purpose; 

(d) all money and property heretofore, now or hereafter delivered to or deposited with Bank or otherwise coming into the possession,
custody or control of Bank (or any agent or bailee of Bank) in any manner or for any purpose whatsoever during the existence of this Agreement and whether held in a general or special account or deposit for safekeeping or otherwise; 
 (e) all right, title and interest of Debtor under licenses, guaranties, warranties, management agreements, marketing or sales agreements,
escrow contracts, indemnity agreements, insurance policies, service or maintenance agreements, supporting obligations and other similar contracts of every kind in which Debtor now has or at any time hereafter shall have an interest; 
 (f) all goods, tools, machinery, furnishings, furniture and other equipment and fixtures of every kind now existing or hereafter acquired,
and all improvements, replacements, accessions and additions thereto and embedded software included therein, whether located on any property owned or leased by Debtor or elsewhere, including without limitation, any of the foregoing now or at any
time hereafter located at or installed on the land or in the improvements at any of the real property owned or leased by Debtor, and all such goods after they have been severed and removed from any of said real property; and 

 (g) all motor vehicles, trailers, mobile homes, manufactured homes, boats, other rolling
stock and related equipment of every kind now existing or hereafter acquired and all additions and accessories thereto, whether located on any property owned or leased by Debtor or elsewhere; 
 together with all of Debtor’s books and records relating to the foregoing, and whatever is receivable or received when any of the foregoing or the proceeds thereof
are sold, leased, licensed, collected, exchanged or otherwise disposed of, whether such disposition is voluntary or involuntary, including without limitation, (i) all rights to payment, including returned premiums, with respect to any insurance
relating to any of the foregoing, (ii) all rights to payment with respect to any claim or cause of action affecting or relating to any of the foregoing, and (iii) all stock rights, rights to subscribe, stock splits, liquidating dividends,
cash dividends, dividends paid in stock, new securities or other property of any kind which Debtor is or may hereafter be entitled to receive on account of any securities pledged hereunder, including without limitation, stock received by Debtor due
to stock splits or dividends paid in stock or sums paid upon or in respect of any securities pledged hereunder upon the liquidation or dissolution of the issuer thereof (collectively, “Proceeds”). 
 Notwithstanding the foregoing, the Collateral shall not include any (i) Intellectual Property; provided, however, that the Collateral shall include all accounts and
general intangibles that consist of rights to payment and proceeds from the sale, licensing or disposition of all or any part of, or rights in, the foregoing (the “Rights to Payment”), or (ii) capital stock of any Excluded Foreign
Subsidiary in excess of 65% of the voting power of all classes of stock of such Excluded Foreign Subsidiary entitled to vote. Notwithstanding the foregoing, if a judicial authority (including a U.S. Bankruptcy Court) holds that a security interest
in the underlying Intellectual Property is necessary to have a security interest in the Rights to Payment, then the Collateral shall automatically, and effective as of the date hereof, include the Intellectual Property to the extent necessary to
permit perfection of Bank’s security interest in the Rights to Payment.

 3. TERMINATION. This Agreement will terminate upon the performance of all obligations (other than
inchoate indemnity obligations) of Debtor to Bank, including without limitation, the payment of all Indebtedness of Debtor to Bank, and the termination of all commitments of Bank to extend credit to Debtor. Upon termination of this Agreement, Bank
shall, at Debtor’s sole cost and expense, release its Liens in the Collateral and all rights therein shall revert to Debtor. 
 4.
OBLIGATIONS OF BANK. Bank has no obligation to make any loans hereunder. Any money received by Bank in respect of the Collateral may be deposited, at Bank’s option, into a non-interest bearing account over which Debtor shall have no control,

of such Collateral and Proceeds, and such duty shall not include any obligation to ascertain or to initiate any action with respect to or to inform Debtor of maturity dates, conversion, call or exchange rights, or offers to purchase the Collateral
or Proceeds, or any similar matters, notwithstanding Bank’s knowledge of the same. Bank shall have no duty to take any steps necessary to preserve the rights of Debtor against prior parties, or to initiate any action to protect against the
possibility of a decline in the market value of the Collateral or Proceeds. Bank shall not be obligated to take any action with respect to the Collateral or Proceeds requested by Debtor unless such request is made in writing and Bank determines, in
its good faith discretion, that the requested action would not unreasonably jeopardize the value of the Collateral and Proceeds as security for the Indebtedness.

irrevocable until termination of this Agreement and may be exercised from time to time by Bank’s officers and employees, or any of them, whether or not Debtor is in default: (a) to perform any obligation of Debtor hereunder in

foregoing, however, that the power of attorney herein granted (other than with respect to items (d), (f), (i), (m) and (r) above which may be
exercised at any time) shall be exercisable only upon the occurrence and during the continuation of an Event of Default unless in Bank’s good faith opinion prompt action is necessary to preserve or protect the Collateral or Bank’s security
interest in the Collateral. To effect the purposes of this Agreement or otherwise upon instructions of Debtor, Bank may cause any Collateral and/or Proceeds to be transferred to Bank’s name or the name of Bank’s nominee. If an Event of
Default has occurred and is continuing, any or all Collateral and/or Proceeds consisting of securities may be registered, without notice, in the name of Bank or its nominee, and thereafter Bank or its nominee may exercise, without notice, all voting
and corporate rights at any meeting of the shareholders of the issuer thereof, any and all rights of conversion, exchange or subscription, or any other rights, privileges or options pertaining to such Collateral and/or Proceeds, all as if it were
the absolute owner thereof. The foregoing shall include, without limitation, the right of Bank or its nominee to exchange, at its discretion, any and all Collateral and/or Proceeds upon the merger, consolidation, reorganization, recapitalization or
other readjustment of the issuer thereof, or upon the exercise by the issuer thereof or Bank of any right, privilege or option pertaining to any shares of the Collateral and/or Proceeds, and in connection therewith, the right to deposit and deliver
any and all of the Collateral and/or Proceeds with any committee, depository, transfer agent, registrar or other designated agency upon such terms and conditions as Bank may determine. All of the foregoing rights, privileges or options may be
exercised without liability on the part of Bank or its nominee except to account for property actually received by Bank. Bank shall have no duty to exercise any of the foregoing, or any other rights, privileges or options with respect to the
Collateral or Proceeds and shall not be responsible for any failure to do so or delay in so doing. 
 8. PAYMENT OF PREMIUMS, TAXES, CHARGES,
LIENS AND ASSESSMENTS. Debtor agrees to pay, prior to delinquency, all insurance premiums, taxes, charges, Liens and assessments against the Collateral, Proceeds and Rights to Payment, and upon the failure of Debtor to do so, Bank at its option may
pay any of them and shall be the sole judge of the legality or validity thereof and the amount necessary to discharge the same. Any such payments made by Bank shall be obligations of Debtor to Bank, due and payable immediately upon demand, together
with interest at a rate determined in accordance with the provisions of this Agreement, and shall be secured by the Collateral, Proceeds and Rights to Payment, subject to all terms and conditions of this Agreement. 
 9. EVENTS OF DEFAULT. The occurrence of any Event of Default under the Credit Agreement shall constitute an “Event of Default” under this
Agreement. 
 10. REMEDIES. Upon the occurrence and during the continuance of any Event of Default, Bank shall have the right to declare
immediately due and payable all or any Indebtedness secured hereby and to terminate any commitments to make loans or otherwise extend credit to Debtor. Bank shall have all other rights, powers, privileges and remedies granted to a secured party upon
default under the California Uniform Commercial Code or otherwise provided by law, including without limitation, the right (a) to contact all Persons obligated to Debtor on any Collateral, Proceeds or Rights to Payment and to instruct such
Persons to deliver all the Collateral, Proceeds and/or Rights to Payment directly to Bank, and (b) to sell, lease, license or otherwise dispose of any or all Collateral. All rights, powers, privileges and remedies of Bank shall be cumulative.
No delay, failure or discontinuance of Bank in exercising any right, power, privilege or remedy hereunder shall affect or operate as a

waiver of such right, power, privilege or remedy; nor shall any single or partial exercise of any such right, power, privilege or remedy preclude, waive or
otherwise affect any other or further exercise thereof or the exercise of any other right, power, privilege or remedy. Any waiver, permit, consent or approval of any kind by Bank of any default hereunder, or any such waiver of any provisions or
conditions hereof, must be in writing and shall be effective only to the extent set forth in writing. It is agreed that public or private sales or other dispositions, for cash or on credit, to a wholesaler or retailer or investor, or user of
property of the types subject to this Agreement, or public auctions, are all commercially reasonable since differences in the prices generally realized in the different kinds of dispositions are ordinarily offset by the differences in the costs and
credit risks of such dispositions. While an Event of Default exists: (a) Debtor will deliver to Bank from time to time, as requested by Bank, current lists of all the Collateral, Proceeds and Rights to Payment; (b) Debtor will not dispose
of any Collateral, Proceeds or Rights to Payment except on terms approved by Bank; (c) at Bank’s request, Debtor will assemble and deliver all Collateral, Proceeds and Rights to Payment, and books and records pertaining thereto, to Bank at
a reasonably convenient place designated by Bank; and (d) Bank may, without notice to Debtor, enter onto Debtor’s premises and take possession of the Collateral. With respect to any sale or other disposition by Bank of any Collateral
subject to this Agreement, Debtor hereby expressly grants to Bank the right to sell such Collateral using any or all of Debtor’s trademarks, trade names, trade name rights and/or proprietary labels or marks. Debtor further agrees that Bank
shall have no obligation to process or prepare any Collateral for sale or other disposition. For any Collateral or Proceeds consisting of securities, Bank shall have no obligation to delay a disposition of any portion thereof for the period of time
necessary to permit the issuer thereof to register such securities for public sale under any applicable state or federal law, even if the issuer thereof would agree to do so. 
 11. DISPOSITION OF COLLATERAL AND PROCEEDS; TRANSFER OF INDEBTEDNESS. In disposing of Collateral hereunder, Bank may disclaim all warranties of title,
possession, quiet enjoyment and the like. Any proceeds of any disposition of any Collateral, Proceeds or Rights to Payment, or any part thereof, may be applied by Bank to the payment of expenses incurred by Bank in connection with the foregoing,
including reasonable attorneys’ fees, and the balance of such proceeds may be applied by Bank toward the payment of the Indebtedness in such order of application as Bank may from time to time elect. Upon the transfer of all or any part of the
Indebtedness, Bank may transfer all or any part of the Collateral, Proceeds or Rights to Payment and shall be fully discharged thereafter from all liability and responsibility with respect to any of the foregoing so transferred, and the transferee
shall be vested with all rights and powers of Bank hereunder with respect to any of the foregoing so transferred; but with respect to any Collateral, Proceeds or Rights to Payment not so transferred, Bank shall retain all rights, powers, privileges
and remedies herein given. 
 12. STATUTE OF LIMITATIONS. Until all Indebtedness shall have been paid in full and all commitments by Bank to
extend credit to Debtor have been terminated, the power of sale or other disposition and all other rights, powers, privileges and remedies granted to Bank hereunder shall continue to exist and may be exercised by Bank at any time and from time to
time irrespective of the fact that the Indebtedness or any part thereof may have become barred by any statute of limitations, or that the personal liability of Debtor may have ceased, unless such liability shall have ceased due to the payment in
full of all Indebtedness secured hereunder.

SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24b-2 OF
THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 

 13. MISCELLANEOUS. Debtor hereby waives any right to require Bank to (i) proceed against Debtor or
any other Person, (ii) marshal assets or proceed against or exhaust any security from Debtor or any other Person, (iii) perform any obligation of Debtor with respect to the Collateral, Proceeds or Rights to Payment, and (d) make any
presentment or demand, or give any notice of nonpayment or nonperformance, protest, notice of protest or notice of dishonor hereunder or in connection with any Collateral or Proceeds. Debtor further waives any right to direct the application of
payments or security for any Indebtedness of Debtor or indebtedness of customers of Debtor. 
 14. NOTICES. All notices, requests and demands
required under this Agreement must be in writing, addressed to Bank at the address specified in any other loan documents entered into between Debtor and Bank and to Debtor at the address of its chief executive office (or principal residence, if
applicable) specified below or to such other address as any party may designate by written notice to each other party, and shall be deemed to have been given or made as follows: (a) if personally delivered, upon delivery; (b) if sent by
mail, upon the earlier of the date of receipt or three (3) days after deposit in the U.S. mail, first class and postage prepaid; and (c) if sent by telecopy, upon receipt. 
 15. COSTS, EXPENSES AND ATTORNEYS’ FEES. Debtor shall pay to Bank immediately upon demand the full amount of all payments, advances, charges, costs
and expenses, including reasonable attorneys’ fees (to include outside counsel fees and all allocated costs of Bank’s in-house counsel), expended or incurred by Bank in connection with (a) the perfection and preservation of the
Collateral or Bank’s interest therein, and (b) the realization, enforcement and exercise of any right, power, privilege or remedy conferred by this Agreement, whether incurred at the trial or appellate level, in an arbitration proceeding
or otherwise, and including any of the foregoing incurred in connection with any bankruptcy proceeding (including without limitation, any adversary proceeding, contested matter or motion brought by Bank or any other Person) relating to Debtor or in
any way affecting any of the Collateral or Bank’s ability to exercise any of its rights or remedies with respect thereto. All of the foregoing shall be paid by Debtor with interest from the date of demand until paid in full at a rate per annum
equal to the greater of ten percent (10%) or Bank’s Prime Rate in effect from time to time. 
 16. SUCCESSORS; ASSIGNS; AMENDMENT.
This Agreement shall be binding upon and inure to the benefit of the heirs, executors, administrators, legal representatives, successors and assigns of the parties, and may be amended or modified only in writing signed by Bank and Debtor.

 17. SEVERABILITY OF PROVISIONS. If any provision of this Agreement shall be held to be prohibited by or invalid under applicable law, such
provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or any remaining provisions of this Agreement. 
 18. DEFINED TERMS. All capitalized terms used herein without definitions shall have the respective meanings assigned to such terms in the Credit
Agreement. All terms not defined in the Credit Agreement that are defined in the UCC and used herein shall have the meanings assigned to such terms in the UCC.
