THIS
WARRANT CERTIFIES THAT, in consideration of the payment of $1.00 and for other good and valuable consideration, COMERICA BANK CALIFORNIA, or its assignee ("Holder") is entitled to
purchase the number of fully paid and nonassessable shares of the class of securities (the "Shares") of the corporation (the "Company") at the initial exercise price per Share (the "Warrant Price")
all as set forth above and as adjusted pursuant to Article 2 of this warrant, subject to the provisions and upon the terms and conditions set forth in this warrant.

ARTICLE
1.EXERCISE.

1.1Method of Exercise.Holder may exercise this warrant by delivering this warrant and a duly executed Notice
of Exercise in substantially the form attached as Appendix 1 to the principal office of the Company. Unless Holder is exercising the conversion right set forth in Section 1.2, Holder
shall also deliver to the Company a check for the aggregate Warrant Price for the Shares being purchased.

1.2Conversion Right.In lieu of exercising this warrant as specified in Section 1.1, Holder may from
time to time convert this warrant, in whole or in part, into a number of Shares determined by dividing (a) the aggregate fair market value of the Shares or other securities otherwise issuable
upon exercise of this warrant minus the aggregate Warrant Price of such Shares by (b) the fair market value of one Share. The fair market value of the Shares shall be determined pursuant to
Section 1.3.

1.3Fair Market Value.If the Shares are traded regularly in a public market, the fair market value of the
Shares shall be the average closing price of the Shares (or the closing price of the Company's stock into which the Shares are convertible) reported for the ten (10) business days immediately
before Holder delivers its Notice of Exercise to the Company. If the Shares are not regularly traded in a public market, the Board of Directors of the Company shall determine fair market value in its
reasonable good faith judgment. The foregoing notwithstanding, if Holder advises the Board of Directors in writing that Holder disagrees with such determination, then the Company and Holder shall
promptly agree upon a reputable investment banking firm to undertake such valuation. If the valuation of such investment banking firm is greater than that determined by the Board of Directors, then
all fees and expenses of such investment banking firm shall be paid by the Company. In all other circumstances, such fees and expenses shall be paid by Holder.

1.4Delivery of Certificate and New Warrant.Promptly after Holder exercises or converts this warrant the
Company shall deliver to Holder certificates for the Shares acquired and, if this warrant has not been fully exercised or converted and has not expired, a new warrant representing the Shares not so
acquired.

1.5Replacement of Warrants.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.

1.6Repurchase on Sale, Merger, or Consolidation of the Company.



ARTICLE
2.ADJUSTMENTS TO THE SHARES.

2.1Stock, Dividends, Splits, Etc.If the Company declares or pays a dividend on its common stock payable in
common stock, or other securities, subdivides the outstanding common stock into a greater amount of common stock, then upon exercise of this warrant, for each Share acquired, Holder shall receive,
without cost to Holder, the total number and kind of securities to which Holder would have been entitled had Holder owned the Shares of record as of the date the dividend or subdivision occurred.

2.2Reclassification, Exchange or Substitution.Upon any reclassification, exchange, substitution, or other
event that results in a change of the number and/or class of the securities issuable upon exercise or
conversion of this warrant, Holder shall be entitled to receive, upon exercise or conversion of this warrant, the number and kind of securities and property that Holder would have received for the
Shares if this warrant had been exercised immediately before such reclassification, exchange, substitution, or other event. Such an event shall include any automatic conversion of the outstanding or
issuable securities of the Company of the same class or series as the Shares to common stock pursuant to the terms of the Company's Certificate of Incorporation upon the closing of a registered public
offering of the Company's common stock. The Company or its successor shall promptly issue to Holder a new warrant for such new securities or other property. The new warrant shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this

2

---

Article 2 including, without limitation, adjustments to the Warrant Price and to the number of securities or property issuable upon exercise of the new warrant. The provisions of this
Section 2.2 shall similarly apply to successive reclassifications, exchanges, substitutions, or other events.

2.3No Impairments.The Company shall not, by amendment of its Certificate of Incorporation or through a
reorganization, transfer of assets, consolidation, merger, dissolution, issue, or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the
terms to be observed or performed under this warrant by the Company, but shall at all times in good faith assist in carrying out all the provisions of this Article 2 and in taking all such
action as may be necessary or appropriate to protect Holder's rights under this Article against impairment. If the Company takes any action affecting the Shares or its common stock other than as
described above that adversely affects Holder's rights under this warrant, the Warrant Price shall be adjusted downward and the number of Shares issuable upon exercise of this warrant shall be
adjusted upward in such a manner that the aggregate Warrant Price of this warrant is unchanged.

2.4Certificate as to Adjustments.Upon each adjustment of the Warrant Price, the Company at its expense shall
promptly compute such adjustment and furnish Holder with a certificate of its Chief Financial Officer setting forth such adjustment and the facts upon which such adjustment is based. The Company
shall, upon written request, furnish Holder a certificate setting forth the Warrant Price in effect upon the date thereof and the series of adjustments leading to such Warrant Price.

ARTICLE
3.REPRESENTATIONS AND COVENANTS OF THE COMPANY.

3.1Representations and Warranties.The Company hereby represents and warrants to the Holder as follows:



3.2Notice of Certain Events.If the Company proposes at any time (a) to declare any dividend or

class or series of its stock any additional shares of stock of any class or series or other rights; (c) to effect any reclassification or recapitalization of common stock; or (d) to
merge or consolidate with or into any other corporation, or sell, lease, license, or convey all or substantially all of its assets, or to liquidate, dissolve or wind up, then, in connection with each
such event, the Company shall give Holder (1) at least 20 days prior written notice of the date on which a record will be taken for such dividend, distribution, or subscription rights (and
