This Warrant may be exercised by delivering to the Company (a) the payment of the Exercise Price for the number of Warrant Shares being purchased, (b) the original of this Warrant, and (c) a duly completed and signed Notice of Exercise in the form of Exhibit A attached hereto.

Notwithstanding the foregoing, for all purposes including voting rights and distribution rights, the Holder shall be deemed to be the holder of the securities issuable upon exercise of this Warrant, effective as of the date of such exercise.

3.4 No Fractional Shares. No fractional shares shall be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the fair market value of a Warrant Share as of the Exercise Date, as determined in good faith by the Board of Directors of the Company.

The Exercise Price and the number and class of securities issuable upon the exercise of this Warrant shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

4.1 Adjustment for Reclassification or Reorganization. In case of any reclassification, conversion or change of the outstanding securities of the Company or of any reorganization of the Company, then and in each such case the Holder of this Warrant, upon the exercise hereof at any time after the consummation of such reclassification, change, or reorganization, shall be entitled to receive, in lieu of or in addition to the stock or other securities and property receivable upon the exercise hereof prior to such consummation, the stock or other securities to which such Holder would have been entitled upon such consummation if such Holder had exercised this Warrant immediately prior thereto, all subject to further adjustment as provided in this Section 4; in each such case, the terms of this Section 4 shall be applicable to the shares of stock or other securities and property receivable upon the exercise of this Warrant after such consummation.

4.2 Stock Splits and Reverse Stock Splits. If the Company shall subdivide its outstanding shares of Preferred Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision shall thereby be proportionately reduced and the number of Warrant Shares receivable upon exercise of this Warrant shall thereby be proportionately increased; and, conversely, if the outstanding number of shares of Preferred Stock shall be combined into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall thereby be proportionately increased and the number of Warrant Shares receivable upon exercise of the Warrant shall be proportionately decreased.

- 4 -

subsidiary), or the sale or distribution of all or substantially all of the Company’s property and assets (the “Reorganization Event”), or (c) any proposed filing of a registration statement under the Act in connection with a primary public offering of the Company’s Common Stock (the “Registration Event”), the Company will mail or cause to be mailed to the Holder a notice specifying (i) the date of any such Distribution stating the amount and character of such Distribution, (ii) the date on which any such Reorganization Event or Registration Event is expected to become effective, and (iii) the time, if any, that is to be fixed as to when the holders of record of the Company’s securities shall be entitled to exchange their shares of the Company’s securities for securities or other property deliverable upon such Reorganization Event. Such notice shall be mailed at least fifteen (15) days prior to the date therein specified.

6.1 Compliance with Act. The Holder, by acceptance hereof, agrees that this Warrant and the Warrant Shares to be issued upon the exercise hereof are being acquired solely for its own account and not as a nominee for any other party and not with a view toward the resale or distribution thereof and that it will not offer, sell or otherwise dispose of this Warrant or any Warrant Shares to be issued upon the exercise hereof except under circumstances which will not result in a violation of the Act. Upon the exercise of this Warrant, the Holder shall confirm in writing, in a form satisfactory to the Company, that the Warrant Shares so issued are being acquired solely for its own account and not as a nominee for any other party and not with a view toward resale or distribution thereof in violation of the Act. This Warrant and the Warrant Shares to be issued upon the exercise hereof (unless registered under the Act and unless, in the case of the Warrant Shares, such Warrant Shares may thereupon be sold pursuant to Commission Rule 144) shall be imprinted with a legend in substantially the following form:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 UNDER SUCH ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

In addition, this Warrant and the Warrant Shares to be issued upon the exercise hereof shall bear any legends required by the securities laws of any applicable states.

6.2 Transferability and Negotiability of Warrant. This Warrant may not be transferred or assigned in whole or in part without compliance with all applicable federal and

- 5 -

state securities laws by the transferor and the transferee (including the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company, if requested by the Company and the transfer is to a person other than a general partner of the initial Holder). Subject to the provisions of this Warrant with respect to compliance with the Act, title to this Warrant may be transferred by endorsement and delivery in the same manner as a negotiable instrument transferable by endorsement and delivery. The Company shall act promptly to record transfers of this Warrant on its books, but the Company may treat the registered holder of this Warrant as the absolute owner of this Warrant for all purposes, notwithstanding any notice to the contrary.

6.3 Disposition of Warrant Shares. With respect to any offer, sale, transfer or other disposition of any Warrant Shares acquired pursuant to the exercise of this Warrant prior to registration of such Warrant Shares, except for any such offer, sale, transfer or other disposition of Warrant Shares to a partner of the initial Holder, the Holder and each subsequent holder of this Warrant agrees to give written notice to the Company prior thereto, describing briefly the manner thereof, together with a written opinion of legal counsel for such holder, reasonably satisfactory to the Company and its legal counsel, if requested by the Company, to the effect that such offer, sale or other disposition may be effected without registration or qualification (under the Act or any other federal or state securities laws) of such Warrant Shares and indicating whether or not under the Act, certificates for such Warrant Shares to be sold or otherwise disposed of require any restrictive legend as to the applicable restrictions on transferability in order to ensure compliance with the Act. Promptly upon receiving such written notice and reasonably satisfactory opinion, if so requested, the Company, as promptly as practicable, shall notify such holder that such holder may sell or otherwise dispose of such Warrant Shares, all in accordance with the terms of the notice delivered to the Company. If a determination has been made pursuant to this Section 6.3 that the opinion of legal counsel for the holder is not reasonably satisfactory to the Company and its legal counsel, the Company shall so notify the holder promptly after such determination has been made. Notwithstanding the foregoing, such Warrant Shares may be offered, sold or otherwise disposed of in accordance with Rule 144, provided that the Company shall have been furnished with such information as the Company may reasonably request to provide a reasonable assurance that the provisions of Rule 144 have been satisfied. Each certificate representing the Warrant Shares thus transferred (except a transfer pursuant to Rule 144 or an effective registration statement) shall bear a restrictive legend as to the applicable restrictions on transferability in order to ensure compliance with the Act, unless in the aforesaid opinion of legal counsel for the holder, such legend is not required in order to ensure compliance with the Act. The Company may issue stop transfer instructions to its transfer agent in connection with such restrictions.

No Holder shall be entitled to vote or receive dividends or be deemed the holder of Warrant Shares or any other securities of the Company which may at any time be issuable on the exercise of this Warrant for any purpose, nor shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, consolidation, merger, transfer of

- 6 -

assets or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until this Warrant shall have been exercised and the Warrant Shares issuable upon exercise hereof shall have become deliverable, as provided herein.

On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor.

Subject to the other provisions of this Warrant, on surrender of this Warrant for exchange, properly endorsed and subject to the provisions of this Warrant with respect to compliance with the Act, the Company at its expense shall issue to or on the order of the Holder a new warrant or warrants of like tenor, in the name of the Holder or as the Holder (on payment by the Holder of any applicable transfer taxes) may direct, for the number of Warrant Shares issuable upon exercise thereof.

This Warrant shall terminate and no longer be exercisable at upon the earlier to occur of (i) the termination of the Exercise Period; or (ii) a Reorganization Event (as defined in Section 5); provided that the Company shall have provided notice of any such Reorganization Event in accordance with Section 5.

All notices and other communications from the Company to the Holder, or vice versa, when given in accordance with Section 5.5 of the Purchase Agreement, shall be deemed delivered and effective at the times specified therein.

Any provision of this Warrant may be amended or waived at any time upon the written consent of (i) the Company, and (ii) the holders of Warrants issued pursuant to the Purchase Agreement representing a majority of the Warrant Shares then issuable upon exercise of all such Warrants issued pursuant to the Purchase Agreement.

Any legal proceedings arising from or relating to this Warrant shall be filed exclusively in the courts located in San Diego County, California, and each holder hereof consents to the jurisdiction of any such court and proceedings.
