        THIS
WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for other good and valuable
consideration, SILICON VALLEY BANK (“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. 



        1.1
Method of Exercise. Holder may exercise this Warrant by delivering a duly executed
Notice of Exercise in substantially the form attached as Appendix 1 to the principal
office of the Company set forth in Section 5.5 of this Warrant. 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. 



        1.2
Conversion 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. 



        1.3
Fair Market Value. If the Shares are traded in a public market, the fair market
value of the Shares shall be the closing price of the Shares (or the closing price of the
Company’s stock into which the Shares are convertible) reported for the business day
immediately before Holder delivers its Notice of Exercise to the Company. If the Shares
are not traded in a public market, the Board of Directors of the Company shall determine
fair market value in its reasonable good faith judgment. 



        1.4
Delivery 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. 



        1.5
Replacement 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, or surrender and
cancellation of this Warrant, the Company shall execute and deliver, in lieu of this
Warrant, a new warrant of like tenor. 





        1.6
Assumption on Sale, Merger, or Consolidation of the Company. 
                1.6.1    "Acquisition".  For the purpose of this Warrant,  "Acquisition" means any sale,

license, or other disposition of all
or substantially all of the assets of the Company, or any reorganization, consolidation,
or merger of the Company where the holders of the Company’s securities before the
transaction beneficially own less than 50% of the outstanding voting securities of the
surviving entity after the transaction. 

                1.6.2
Assumption  of Warrant.  Upon the  closing of any  Acquisition,  the  successor

entity shall assume the obligations
of this Warrant, and this Warrant shall be exercisable for the same securities, cash, and
property as would be payable for the Shares issuable upon exercise of the unexercised
portion of this Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Initial Exercise Price and/or number of Shares
shall be adjusted accordingly. 


ARTICLE 2. ADJUSTMENTS TO THE
SHARES. 



        2.1
Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on its
common stock (or the Shares if the Shares are securities other than common stock) payable
in common stock, or other securities, subdivides the outstanding common stock into a
greater amount of common stock, or, if the Shares are securities other than common stock,
subdivides the Shares in a transaction that increases the amount of common stock into
which the Shares are convertible, 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. If the outstanding shares are
combined or consolidated, by reclassification or otherwise, into a lesser number of
shares, the Initial Exercise Price shall be proportionately increased. 



        2.2
Reclassification, Exchange, Combinations 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 Articles
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 Article 2 including, without limitation, adjustments to the Initial Exercise 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. 



	          2.3
Adjustments for Diluting Issuances. The Warrant Price and the number of Shares
issuable upon exercise of this Warrant or, if the Shares are Preferred Stock, the number
of shares of common stock issuable upon conversion of the Shares, shall be subject to
adjustment, from time to time in the manner set forth in the Company’s Certificate of
Incorporation. The provisions set forth for the Shares in the Company’s Certificate
of Incorporation relating to the above in effect as of the Issue Date may not be amended,
modified or waived, without the prior written consent of Holder unless such amendment,
modification or waiver affects Holder in the same manner as they affect all other
shareholders of the same series of shares granted to Holder. 










        2.4
No Impairment. The Company shall not, by amendment of its Articles 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 of 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. 


        2.5
Fractional Shares. No fractional Shares shall be issuable upon exercise or
conversion of the Warrant and the number of Shares to be issued shall be rounded down to
the nearest whole Share. If a fractional share interest arises upon any exercise or
conversion of the Warrant, the Company shall eliminate such fractional share interest by
paying Holder the amount computed by multiplying the fractional interest by the fair
market value of a full Share. 



        2.6
Certificate as to Adjustments. Upon each adjustment of the Warrant Price, the
Company shall promptly notify Holder in writing, and, at the Company’s expense,
promptly compute such adjustment, and furnish Holder with an officer’s certificate
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. 


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

follows: 


                 (a) The initial Warrant Price referenced on the first page of this Warrant is not
          greater than (i) the price per share at which the Shares were last issued in an
          arms-length transaction in which at least $500,000 of the Shares were sold and
          (ii) the fair market value of the Shares as of the date of this Warrant. 



                 (b) All Shares which may be issued upon the exercise of the purchase right
          represented by this Warrant, and all securities, if any, issuable upon
          conversion of the Shares, shall, upon issuance, be duly authorized, validly
          issued, fully paid and nonassessable, and free of any liens and encumbrances
          except for restrictions on transfer provided for herein or under applicable
          federal and state securities laws. 



                 (c) The capitalization table previously provided to Holder remains true and complete
          as of the Issue Date. 



        3.2
Notice of Certain Events. If the Company proposes at any time (a) to
declare any dividend or distribution upon its common stock, whether in cash,
property, stock, or other securities and whether or not a regular cash dividend;
(b) to offer for subscription pro rata to the holders of any 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; (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; or (e) offer holders of registration rights the opportunity
to participate in an underwritten public offering of the Company’s securities 





for cash, then, in
connection with each such event, the Company shall give Holder (1) at least 10
days prior written notice of the date on which a record will be taken for such
dividend, distribution, or subscription rights (and specifying the date on which
the holders of common stock will be entitled thereto) or for determining rights
to vote, if any, in respect of the matters referred to in (c) and (d) above; (2)
in the case of the matters referred to in (c) and (d) above at least 10 days
prior written notice of the date when the same will take place (and specifying
the date on which the holders of common stock will be entitled to exchange their
common stock for securities or other property deliverable upon the occurrence of
such event); and (3) in the case of the matter referred to in (e) above, the
same notice as is given to the holders of such registration rights. 



        3.3
Registration Under Securities Act of 1933, as amended. The Company agrees that the
Shares shall be entitled to the registration rights set forth in the Company’s Unit
Purchase Agreement dated December 31, 2001. The provisions set forth in the Company’s
Unit Purchase Agreement relating to the above in effect as of the Issue Date may not be
amended, modified or waived without the prior written consent of Holder unless such
amendment, modification or waiver affects Holder in the same manner as they affect all
other shareholders of the same series of shares granted to the Holder .

        4.1
Purchase for Own Account. Except for transfers to Holder’s affiliates, this
Warrant and the securities to be acquired upon exercise of this Warrant by the Holder will

possessed such information or could acquire it without unreasonable effort or expense)
necessary to verify any information furnished to the Holder or to which the Holder has
access. 



        4.3
