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.

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

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.
