 ATTACHMENT I 
 CERUS CORPORATION 
 2008 EQUITY
INCENTIVE PLAN 
 OPTION AGREEMENT 
 (INCENTIVE STOCK OPTION OR NONSTATUTORY STOCK
OPTION) 
 Pursuant to your Option Grant Notice (“Grant Notice”) and this Option Agreement, Cerus
Corporation (the “Company”) has granted you an option under its 2008 Equity Incentive Plan (the “Plan”) to purchase the number of shares of the Company’s Common Stock indicated in your Grant
Notice at the exercise price indicated in your Grant Notice. Defined terms not explicitly defined in this Option Agreement but defined in the Plan shall have the same definitions as in the Plan. 
 The details of your option are as follows: 
 1. VESTING. Subject to the limitations contained herein, your option will vest as provided in your Grant Notice, provided that vesting will cease upon the termination of your Continuous Service. 
 2. NUMBER OF SHARES AND EXERCISE PRICE. The
number of shares of Common Stock subject to your option and your exercise price per share referenced in your Grant Notice may be adjusted from time to time for Capitalization Adjustments. 
 3. EXERCISE RESTRICTION FOR NON-EXEMPT EMPLOYEES.
In the event that you are an Employee eligible for overtime compensation under the Fair Labor Standards Act of 1938, as amended (i.e., a “Non-Exempt Employee”), and except as otherwise provided in the Plan, you may not
exercise your option until you have completed at least six (6) months of Continuous Service measured from the Date of Grant specified in your Grant Notice, notwithstanding any other provision of your option. 
 4. METHOD OF PAYMENT. Payment of the exercise price is due in full upon exercise of all or any
part of your option. You may elect to make payment of the exercise price in cash or by check or in one or more of the following manners: 
 (a) Provided that at the time of exercise the Common Stock is publicly traded, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of
Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds. 
 (b) Provided that at the time of exercise the Common Stock is publicly traded, by delivery to the Company (either by actual
delivery or attestation) of already-owned shares of Common Stock that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on the date of exercise. “Delivery” for these
purposes, in the sole discretion of the Company at the time you exercise your option, shall include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form approved by the Company. Notwithstanding the
foregoing, you may not exercise your option by tender to the Company of Common Stock to the extent such tender would violate the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. 







 (c) If the Option is a Nonstatutory Stock Option, subject to the consent of the
Company at the time of exercise, by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issued upon exercise of your option by the largest whole number of shares with a Fair Market
Value that does not exceed the aggregate exercise price; provided, however, that the Company shall accept a cash or other payment from you to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the
number of whole shares to be issued; provided further, however, that shares of Common Stock will no longer be outstanding under your option and will not be exercisable thereafter to the extent that (1) shares are used to pay the exercise price
pursuant to the “net exercise,” (2) shares are delivered to you as a result of such exercise, and (3) shares are withheld to satisfy tax withholding obligations. 
 5. WHOLE SHARES. You may exercise your option only for whole shares of Common Stock. 
 6. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary contained herein, you
may not exercise your option unless the shares of Common Stock issuable upon such exercise are then registered under the Securities Act or, if such shares of Common Stock are not then so registered, the Company has determined that such exercise and
issuance would be exempt from the registration requirements of the Securities Act. The exercise of your option also must comply with other applicable laws and regulations governing your option, and you may not exercise your option if the Company
determines that such exercise would not be in material compliance with such laws and regulations. 
 7. TERM.
You may not exercise your option before the commencement or after the expiration of its term. The term of your option commences on the Date of Grant and expires, subject to the provisions of Section 5(g) of the Plan, upon the earliest of the
following: 
 (a) three (3) months after the termination of your Continuous Service for any reason other than your
Disability or death; provided, however, that if (i) you are a Non-Exempt Employee, (ii) your Continuous Service terminates within six (6) months after the Date of Grant specified in your Grant Notice, and (iii) you have
vested in a portion of your option at the time of your termination of Continuous Service, your option shall not expire until the earlier of (x) the later of (A) the date that is seven (7) months after the Date of Grant specified in
your Grant Notice or (B) the date that is three (3) months after the termination of your Continuous Service, or (y) the Expiration Date; 
 (b) twelve (12) months after the termination of your Continuous Service due to your Disability; 
 (c) eighteen (18) months after your death if you die either during your Continuous Service or within three (3) months after your Continuous Service terminates; or 
 (d) the Expiration Date indicated in your Grant Notice. 







 If your option is an Incentive Stock Option, note that to obtain the federal income tax advantages
associated with an Incentive Stock Option, the Code requires that at all times beginning on the date of grant of your option and ending on the day three (3) months before the date of your option’s exercise, you must be an employee of the
Company or an Affiliate, except in the event of your death or Disability. The Company has provided for extended exercisability of your option under certain circumstances for your benefit but cannot guarantee that your option will necessarily be
treated as an Incentive Stock Option if you continue to provide services to the Company or an Affiliate as a Consultant or Director after your employment terminates or if you otherwise exercise your option more than three (3) months after the
date your employment with the Company or an Affiliate terminates. 
 8. EXERCISE. 
 (a) You may exercise the vested portion of your option during its term by delivering a Notice of Exercise (in a form designated by
the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then require. 

(b) By exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to
enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (i) the exercise of your option, (ii) the lapse of any substantial risk of forfeiture to which
the shares of Common Stock are subject at the time of exercise, or (iii) the disposition of shares of Common Stock acquired upon such exercise. 
 (c) If your option is an Incentive Stock Option, by exercising your option you agree that you will notify the Company in writing within fifteen (15) days after the date of any disposition of any of the
shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the date of your option grant or within one (1) year after such shares of Common Stock are transferred upon exercise of your option.

 9. TRANSFERABILITY. Your option is not transferable, except by will or by the laws of descent and
distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall
thereafter be entitled to exercise your option. In addition, you may transfer your option to a trust if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable state law) while the option is
held in the trust, provided that you and the trustee enter into transfer and other agreements required by the Company. 
 10.
OPTION NOT A SERVICE CONTRACT. Your option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any
obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to continue your employment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective
stockholders, Boards of Directors, Officers or Employees to continue any relationship that you might have as a Director or Consultant for the Company or an Affiliate. 







 11. WITHHOLDING OBLIGATIONS. 
 (a) At the time you exercise your option, in whole or in part, or at any time thereafter as requested by the Company, you hereby
authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless exercise” pursuant to a program developed under Regulation T as promulgated by
the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise of
your option. 
 (b) Upon your request and subject to approval by the Company, in its sole discretion, and compliance
with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common Stock having a Fair Market Value,
determined by the Company as of the date of exercise, not in excess of the minimum amount required to be withheld by law (or such lower amount as may be necessary to avoid classification of your option as a liability for financial accounting
purposes). Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility. 
 (c) You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied. Accordingly, you may not be able to exercise your option when desired even though
your option is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any escrow provided for herein unless such obligations are satisfied. 
 12. TAX CONSEQUENCES. You hereby agree that the Company does not have a duty to
design or administer the Plan or its other compensation programs in a manner that minimizes your tax liabilities. You shall not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities
arising from your option or your other compensation. In particular, you acknowledge that this option is exempt from Section 409A of the Code only if the exercise price per share specified in the Grant Notice is at least equal to the “fair
market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of compensation associated with the option. 
 13. NOTICES. Any notices provided for in your option or the Plan shall be given in writing and shall be deemed effectively given upon receipt or, in the case of notices delivered by mail
by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company. 
 14. GOVERNING PLAN DOCUMENT. Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and is
further subject to all interpretations, amendments, rules and regulations, which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of your option and those of the Plan, the
provisions of the Plan shall control.
