THIS WARRANT AND THE UNDERLYING SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”).

BIOMEDICINES, INC.

WARRANT TO PURCHASE COMMON STOCK

No. CSW-1

November 7, 2002

Void After November 7, 2007

(or earlier as provided herein)

THIS CERTIFIES THAT, for value received, CHIRON CORPORATION, a Delaware corporation, (the “Holder” or “Purchaser”), is entitled to subscribe for and purchase at the Exercise Price (defined below) from BIOMEDICINES, INC., a Delaware corporation, with its principal office at 2000 Xxxxxx Xxxxxx, Xxxxx 0000, Xxxxxxxxxx, Xxxxxxxxxx 00000 (the “Company”) up to one hundred fifty thousand (150,000) shares of Common Stock of the Company (other “Common Stock”), as provided herein.

1. DEFINITIONS. As used herein, the following terms shall have the following respective meanings:

“Exercise Period” shall mean the time period commencing with the date hereof and ending with (a) the earlier of (i) November 7, 2007 or (ii) the third (3rd) anniversary of the date of the closing of the initial public offering of the Company’s Common Stock pursuant to a registration statement under the Securities Act of 1933, as amended, or (b) such earlier time as this Warrant is terminated in accordance with the terms herein.

“Exercise Price” shall mean $6.00 per share, subject to adjustment pursuant to Section 5.1 below.

“Exercise Shares” shall mean the shares of the Company’s Common Stock issuable upon exercise of this Warrant, subject to adjustment pursuant to the terms herein, including but not limited to adjustment pursuant to Section 5.1 below.

2. EXERCISE OF WARRANT. The rights represented by this Warrant may be exercised in whole or in part at any time and from time to time during the Exercise Period, by delivery of the following to the Company at its address set forth above (or at such other address as it may designate by notice in writing to the Holder):

(a) An executed Notice of Exercise in the form attached hereto;

(b) Payment of the Exercise Price in cash or by check; and

(c) This Warrant.

Upon the exercise of the rights represented by this Warrant, a certificate or certificates for the Exercise Shares so purchased, registered in the name of the Holder or persons affiliated with the Holder, if the Holder so designates, shall be issued and delivered to the Holder within thirty (30) days after the rights represented by this Warrant shall have been so exercised.

The person in whose name any certificate or certificates for Exercise Shares are to be issued upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which this Warrant was surrendered and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open.

2.1 Net Exercise. Notwithstanding any provisions herein to the contrary, if the fair market value of one share of the Company’s Common Stock is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant by payment of cash, the Holder may elect (the “Conversion Right”) to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Notice of Exercise in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:

		X =	Y (A-B)
			A

Where X = the number of shares of Common Stock to be issued to the Holder

Y = the number of shares of Common Stock purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being canceled (at the date of such calculation)

A = the fair market value of one share of the Company’s Common Stock (at the date of such calculation)

B = Exercise Price (as adjusted to the date of such calculation)

For purposes of the above calculation, the fair market value of one share of Common Stock shall be:

(a) the average daily Market Price (as defined below) during the period of the most recent ten (10) days, ending on the last business day before the effective date of exercise of the Conversion Right, on which the national securities exchanges were open for trading and; or

(b) if no class of Common Stock is then listed or admitted to trading on any national securities exchange or quoted in the over-counter market, the fair market value shall be the Market Price on the last business day before the effective date of exercise of the Conversion Right.

(c) If the Common Stock is traded on a national securities exchange or admitted to unlisted trading privileges on such an exchange, or is listed on the National Market System (the “National Market System”) of the Nasdaq, the Market Price as of a specified day shall be the last reported sale price of Common Stock on such exchange or on the National Market System on such date or if no such sale is made on such day, the mean of the closing bid and asked prices for such day on such exchange or on the National Market System. If the Common Stock is not so listed or admitted to unlisted trading privileges, the Market Price as of a specified day shall be the mean of the last bid and asked prices reported on such date (x) by the Nasdaq or (y) if reports are unavailable under clause (x) above by the National Quotation Bureau Incorporated. If the Common Stock is not so listed or admitted to unlisted trading privileges and bid and ask prices are not reported, the Market Price as of a specified day shall be determined in good faith by the Board of Directors of the Company.

2.2 Company’s Repurchase Option. Notwithstanding any provision herein to the contrary, if the Common Stock is traded on a national securities exchange or admitted to unlisted trading privileges on such an exchange, or is listed on the National Market System, and the reported closing price per share of the Common Stock exceeds three hundred percent (300%) of the Exercise Price for thirty (30) consecutive trading days (the “Reference Period”), the Company may, at its option, purchase this Warrant from the Holder at a price equal to the product of: (A) the number of shares for which this Warrant is exercisable multiplied by (B) the difference of (i) the highest reported closing price per share of the Common Stock during the period beginning with the first day of the Reference Period and ending the day before the Repurchase Date (as defined below) less (ii) the Exercise Price. If the Company elects to purchase this Warrant, the Company will notify the Holder in writing. The Company and the Holder shall effect the purchase with respect to any portion of this Warrant that has not been exercised by the holder on the twentieth (20th) day following the date of the Company’s written notice regarding the purchase or such earlier date as the Company and the Holder may agree (the “Repurchase Date”). On the Repurchase Date the Company shall pay the Holder the purchase price determined in accordance with the provisions hereof, and the Warrant shall thereafter be void and may not be exercised.

3. COVENANTS OF THE COMPANY.

3.1 Covenants as to Exercise Shares. The Company covenants and agrees that all Exercise Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issuance thereof. The Company further covenants and agrees that the Company will at all times during the Exercise Period, have authorized and reserved, free from preemptive rights, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant. If at any time during the Exercise Period the number of authorized but unissued shares of Common Stock shall not be sufficient to permit exercise of this Warrant, the Company will take such corporate

action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes.

3.2 Notices of Record Date. In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend which is the same as cash dividends paid in previous quarters) or other distribution, the Company shall mail to the Holder, at least ten (10) days prior to the date specified herein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend or distribution.

3.3 Notice of Expiration. If this Warrant has not been fully exercised on or before the date thirty (30) days prior to the end of the Exercise Period, the Company shall thereafter provide Holder with at least twenty (20) days advance written notice of the date on which this Warrant is to expire. If the Company fails to provide such notice, the Exercise Period shall be extended until the date thirty (30) days after the date said notice is provided to Holder.

4. REPRESENTATIONS OF HOLDER AND THE COMPANY.

4.1 Acquisition of Warrant for Personal Account. The Holder represents and warrants that it is acquiring the Warrant and the Exercise Shares solely for its account for investment and not with a view to or for sale or distribution of said Warrant or Exercise Shares or any part thereof, other than potential transfers between affiliates (including affiliated funds). The Holder also represents that the entire legal and beneficial interests of the Warrant and Exercise Shares the Holder is acquiring is being acquired for, and will be held for, its account only.

4.2 Securities Are Not Registered.

(a) The Holder understands that the Warrant and the Exercise Shares have not been registered under the Securities Act of 1933, as amended (the “Act”) on the basis that no distribution or public offering of the stock of the Company is to be effected. The Holder realizes that the basis for the exemption may not be present if, notwithstanding its representations, the Holder has a present intention of acquiring the securities for a fixed or determinable period in the future, selling (in connection with a distribution or otherwise), granting any participation in, or otherwise distributing the securities. The Holder has no such present intention, other than potential transfers between affiliates (including affiliated funds).

(b) The Holder recognizes that the Warrant and the Exercise Shares must be held indefinitely unless they are subsequently registered under the Act or an exemption from such registration is available.

(c) The Holder is aware that neither the Warrant nor the Exercise Shares may be sold pursuant to Rule 144 adopted under the Act unless certain conditions are met, including, among other things, the existence of a public market for the shares, the availability of certain current public information about the Company, the resale following the required holding period under Rule 144 and the number of shares being sold during any three month period not exceeding specified limitations. Holder is aware that the conditions for resale

set forth in Rule 144 have not been satisfied and that the Comopany presently has no plans to satisfy these conditions in the foreseeable future.

4.3 CORPORATE ACTIONS. The Company represents that all corporate actions on the part of the Company, its officers, directors and shareholders necessary for the sale and issuance of the Common Stock pursuant hereto and the performance of the Company’s obligations hereunder were taken prior to and are effective as of the effective date of this Warrant. The Company represents and warrants that it shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, such number of shares of Common Stock as shall from time to time be sufficient to effect the exercise of this Warrant.

5. ADJUSTMENT OF EXERCISE PRICE AND EFFECT OF ORGANIC CHANGES.

5.1 Adjustment of Exercise Price. In the event of changes in the outstanding Common Stock of the Company by reason of stock dividends, splits, recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like, the number and class of shares available under the Warrant in the aggregate and the Exercise Price shall be correspondingly adjusted to give the Holder of the Warrant, on exercise for the same aggregate Exercise Price, the total number, class, and kind of shares as the Holder would have owned had the Warrant been exercised prior to the event and had the Holder continued to hold such shares until after the event requiring adjustment. The form of this Warrant need not be changed because of any adjustment in the number of Exercise Shares subject to this Warrant.

5.2 Reorganization, Reclassification, Consolidation, Merger or Sale. If any recapitalization, reclassification or reorganization of the capital stock of the Company, or any consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its assets or other transaction other than a Cash Liquidity Event (as defined below) shall be effected in such a way that holders of the Company’s Common Stock shall be entitled to receive stock, securities, or other assets or property (an “Organic Change”), then, as a condition of such Organic Change, lawful and adequate provisions shall be made by the Company whereby the Holder hereof shall thereafter have the right to purchase and receive (in lieu of the shares of the Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such shares of stock, securities or other assets or property as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such stock immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby. In the event of any Organic Change, appropriate provision shall be made by the Company with respect to the rights and interests of the Holder of this Warrant to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Exercise Price and of the number of shares purchasable and receivable upon the exercise of this Warrant) shall thereafter be applicable, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. The Company will not effect any such consolidation, merger or sale unless, prior to the consummation thereof, the successor corporation (if other than the Company) resulting from such consolidation or the corporation purchasing such assets shall assume by written instrument mailed or delivered to the registered Holder hereof at the last address of such Holder appearing on the books of the Company, the obligation to deliver to such

Holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such Holder may be entitled to purchase.

5.3 Early Termination. In the event of, at any time during the Exercise Period, any consolidation or merger of the Company with or into any other corporation, person or other entity or a sale, lease or other disposition of all or substantially all of the assets of the Company in which the Exercise Shares are exchanged for cash (each, a “Cash Liquidity Event”), the Company shall provide to the Holder twenty (20) days advance written notice of such Cash Liquidity Event, and this Warrant shall terminate unless exercised prior to the date such Cash Liquidity Event is consummated.

5.4 Certain Events. If any change in the outstanding Common Stock of the Company or any other event occurs as to which the other provisions of this Section 5 are not strictly applicable or if strictly applicable would not fairly protect the purchase rights of the Holder of the Warrant in accordance with such provisions, then the Board of Directors of the Company shall make an adjustment in the number and class of shares available under the Warrant, the Exercise Price or the application of such provisions, so as to protect such purchase rights as aforesaid. The adjustment shall be such as to give the Holder of the Warrant upon exercise for the same aggregate Exercise Price the total number, class and kind of shares as he would have owned had the Warrant been exercised prior to the event and had he continued to hold such shares until after the event requiring adjustment.

5.5 Notice of Adjustments, Organic Changes, etc. Except as otherwise provided herein, in the event of any adjustment to the number of shares of Common Stock pursuant to this Article 5, the Company shall provide to Holder within thirty (30) days of such adjustment a certificate signed by its Chief Financial Officer setting forth, in reasonable detail the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated and the Exercise Price and the number of shares of Common Stock purchasable hereunder after giving effect to such adjustment.

6. REGISTRATION RIGHTS. The Holder will become a party to that certain Amended and Restated Investor Rights Agreement dated September 12, 2000, to include any Common Stock of the Company issued upon exercise of the Warrant in the definition of “Registrable Securities” for purposes of Sections 1.3, 1.4, 1.5, 1.7, 1.8, 1.9, 1.10, 1.11, 1.13, 1.15, 1.16 and 3 thereof.

7. FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Exercise Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current fair market value of an Exercise Share by such fraction.

8. DISPOSITION OF SECURITIES. The Holder agrees not to make any disposition of all or any part of the Warrant or Exercise Shares in any event unless (i) such disposition

is in compliance with the Act, and the Holder shall have provided the Company with a description of the proposed disposition, provided that such description shall not be required, if the disposition is permitted under Rule 144 of the Act or (ii) there is in effect a registration statement under the Act covering the proposed disposition and such disposition is made in accordance with the registration statement.

Notwithstanding the other provisions of this Section 8, the Holder may assign Common Stock (or other securities) of the Company held by such Holder to (i) any partner or retired partner of the Holder, if the Holder is a partnership, (ii) any member or former member of the Holder, if the Holder is a limited liability company, (iii) any affiliate, including affiliated funds, (iv) any family member or trust for the benefit the Holder or a family member, if the Holder is an individual, (v) any successor to the Company, by merger, consolidation or otherwise, or that acquires all or substantially all of the assets of the Holder; provided that the Company is given written notice thereof

9. NO STOCKHOLDER RIGHTS. This Warrant in and of itself shall not entitle the Holder to any voting rights or other rights as a stockholder of the Company.

11. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

12. NOTICES, ETC. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on the next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt.
