WARRANT TO PURCHASE COMMON STOCK

This Warrant certifies that, for good and valuable consideration, Holder, is entitled to purchase from the Company, until 5:00 p.m. Pacific Time, on the Expiration Date set forth above, the number of fully paid and nonassessable shares of the class of stock (the "Shares") of the Company at the Initial Exercise Price per Share (the "Warrant Price"), all as set forth above and as adjusted pursuant to Section 2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant.

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 Exhibit A to the principal office of the Company as well as a joinder agreement to such stockholder agreement or similar agreement as may be in place at the time of such exercise. This Warrant may be exercised in whole or in part and Holder shall also deliver to the Company a check or wire transfer for the aggregate Warrant Price for the Shares being purchased.

1.2 Delivery of Certificate and New Warrant. Promptly after Holder exercises 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, this Warrant shall automatically be reduced by the number of Shares issued and remain exercisable for such remaining Shares not so acquired, and all other terms of the Warrant shall otherwise remain in full force and effect as so adjusted. Upon final exercise of this Warrant for any such remaining number of Shares, this Warrant shall be surrendered by the Holder to the Company for cancellation.

1.3 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 at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor.

1.4 Sale, Merger, Consolidation or Liquidation of the Company.

1.4.1 "Acquisition". For the purpose of this Warrant, "Acquisition" means (a) any sale or exchange of the capital stock by the shareholders of the Company in one transaction or series of related transactions where more than 50% of the outstanding voting power of the Company is acquired by a person or entity or group of related persons or entities; or (b) any reorganization, consolidation, merger or similar transaction or series of related transactions (each, a "combination transaction") in which the Company is a constituent corporation or is a party if, as a result of such combination transaction, the voting securities of the Company that are outstanding immediately prior to the consummation of such combination transaction (other than any such securities that are held by an "Acquiring Shareholder", as defined below) do not represent, or are not converted into, securities of the surviving corporation or resulting company of such combination transaction (or such surviving corporation's parent corporation if the surviving corporation is owned by the parent corporation) that, immediately after the consummation of such combination transaction, together possess at least fifty percent (50%) of the total voting power of all securities of such surviving corporation (or its parent corporation, if applicable) that are outstanding immediately after the consummation of such combination transaction, including securities of such surviving corporation (or its parent corporation, if applicable) that are held by the Acquiring Shareholder; or (c) a sale or other transfer of all or substantially all of the assets of the Company, that is followed by the distribution of the proceeds to the Company's shareholders. For purposes of this Section 1.4.1, an "Acquiring Shareholder" means a shareholder or shareholders of the Company that (i) merges or combines with the Company in such combination transaction or (ii) owns or controls a majority of another corporation that merges or combines with the Company in such combination transaction.

1.4.2 Assumption of Warrant. Upon the closing of any Acquisition where the consideration for the Acquisition to be received by the Company's shareholders consists solely or in part of stock or securities of the acquirer or an entity affiliated with the acquirer, the successor entity shall assume the obligations of this Warrant, and this Warrant shall be exercisable for the same securities 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 thereof. The Warrant Price shall be adjusted accordingly.

1.4.3 Termination of Warrant. In the case of (a) an Acquisition where the consideration for the Acquisition to be received by the Company's shareholders in return for their capital stock of the Company consists of cash or a combination of cash and other property (other than stock or securities of the Acquirer) or (b) the proposed liquidation and dissolution of the Company, the Company shall give Holder at least (30) days advance written notice of such event (the "Company Notice"), which notice shall include the Company's best estimate of the value of the Shares receivable upon exercise or conversion of this Warrant and the proposed date upon which such event is expected to occur. During such notice period, Holder may exercise or convert this Warrant in accordance with its terms, whether or not exercise or conversion is contingent upon the happening of such event and/or existence of a minimum value of the Shares receivable upon exercise or conversion as provided on Holder's exercise notice; provided that such minimum value shall be no greater than the per share price set forth in the Company Notice. Subject to prior exercise or conversion as provided in the preceding sentence, this Warrant will terminate at 5:00 p.m. Pacific Time on the day prior to the date such event is expected to occur as set forth in the Company Notice; provided that (a) the Company Notice of the proposed event is actually received by Holder, as evidenced by a return receipt of certified mail delivery, a certificate of delivery by hand delivery or written verification of delivery from the overnight courier, and (b) the event actually occurs within (30) days after the date it is expected to occur, as such date was specified in the Company Notice.

2. ADJUSTMENTS TO THE SHARES.

2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on the outstanding shares of the Company's Common Stock payable in shares of the Company's Common Stock or other securities of the Company or subdivides or combines the outstanding shares of the Company's Common Stock, then upon exercise or conversion of this Warrant, 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, subdivision or combination occurred.

2.2 Reclassification, 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 (other than a merger, consolidation or recapitalization described in Section 1.4 above or a stock dividend, split, etc. described in Section 2.1 above), 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. 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 Section 2 including, without limitation, appropriate adjustments to the Warrant Price and to the number of securities or property issuable upon exercise or conversion of the new Warrant.

2.3 Adjustments of Warrant Price. If the outstanding Shares are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased. If the outstanding Shares are divided by reclassification or otherwise, into a greater number of shares, the Warrant Price shall be proportionately decreased.

2.4 Adjustment is Cumulative. The provisions of this Section 2 shall similarly apply to successive, stock dividends, stock splits or combinations, reclassifications, exchanges, substitutions, or other events.

2.5 No Impairment. The Company shall not, by amendment of its organizational documents 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 Section 2 and in taking all such action as may be necessary or appropriate to protect Holder's rights under this Section against impairment.

2.6 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 an amount by check computed by multiplying the fractional interest by the fair market value of a full Share.

2.7 Certificate as to Adjustments. Upon each adjustment of the Warrant Price, the Company at its expense shall 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.

3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

3.1 Representations and Warranties. The Company hereby represents and warrants to the Holder that 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 securities laws.

4. REPRESENTATIONS OF HOLDER: TRANSFER.

4.1 Representations. Holder hereby represents and warrants to the Company as follows. Holder is a sophisticated investor having such knowledge and experience in business and investment matters that Holder is capable of protecting Holder's own interests in connection with the acquisition, exercise or disposition of this Warrant. Holder is aware that this Warrant and the Shares are being, or will be, issued to Holder in reliance upon Holder's representation in this Section 4 and that such securities are restricted securities that cannot be publicly sold except in certain prescribed situations. Holder has received such information about the Company as Holder deems reasonable, has had the opportunity to ask questions and receive answers from the Company with respect to its business, assets, prospects and financial condition and has verified any answers Holder has received from the Company with independent third parties to the extent Holder deems necessary. The Holder of this Warrant, by acceptance hereof, acknowledges this Warrant and the Shares to be issued upon exercise hereof or conversion thereof are being acquired solely for the Holder's own account and not as a nominee for any other party, and for investment, and that the Holder will not offer, sell or otherwise dispose of this Warrant or any Shares to be issued upon exercise hereof or conversion thereof except under circumstances that will not result in a violation of the securities laws.

4.2 Legends. This Warrant the certificates representing and the Shares (and the securities issuable, directly or indirectly, upon conversion of the Shares, if any) shall be imprinted with a legend setting forth the applicable restrictions on transfers and market-standoff restrictions.

4.3 Restriction on Transfer and Compliance with Securities Laws on Transfer. This Warrant shall not be transferred in whole or in part, provided, however, that Holder may transfer the Warrant in whole or in part to an Affiliate of the Holder ("Affiliate" is as defined in Rule 405 of the Securities Act of 1933, as amended). Further, this Warrant and the Shares issuable upon exercise of this Warrant (and the securities issuable, directly or indirectly, upon conversion of the Shares, if any) may not be transferred or assigned in whole or in part without compliance with applicable securities laws by the transferor and the transferee (including, without limitation, the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company, as reasonably requested by the Company). The Company shall not require Holder to provide an opinion of counsel if the transfer is to the shareholders or constituent partners of Holders by way of dividend or distribution to all of the same, and the Company is provided with a copy of Holder's notice of proposed sale and/or transfer.

4.4 Transfer Procedure. Subject to the provisions of Section 4.3, Holder may transfer all or part of this Warrant or the Shares issuable upon exercise of this Warrant (or the securities issuable, directly or indirectly, upon conversion of the Shares, if any) by giving the Company a written notice of the portion of the Warrant or such Shares (or such securities) being transferred, such notice setting forth the name, address and taxpayer identification number of the transferee, and, with respect to the Warrant, surrendering this Warrant to the Company for reissuance to the transferee(s) (and to the new Warrant Holder for any remaining Shares, if applicable). The Company shall have the right to refuse to transfer any portion of this Warrant to any person who directly competes with the Company.

4.5 Market Standoff. The Holder agrees in connection with any registration of the Company's securities, upon the request of the underwriters managing any registered public offering of the Company's securities, Holder will not sell or otherwise dispose of any Shares or any other securities of the Company without the prior written consent of such managing underwriters, for a period of time (not to exceed one hundred eighty (180) days) after the effective date of such registration requested by such managing underwriters subject to all restrictions as the managing underwriters may specify generally. Holder further agrees to enter into any agreement reasonably required by the underwriters to implement the foregoing.

In order to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the certificates representing the Shares subject to this Section and to impose stop transfer instructions with respect to the Registrable Securities and such other shares of stock of Holder until the end of such period.

If such clause or provision cannot be so enforced, such provision shall be stricken from this Warrant and the remainder of this Warrant shall be enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent not enforceable) never been contained in this Warrant. Notwithstanding the forgoing, if the value of this Warrant based upon the substantial benefit of the bargain for any party is materially impaired, which determination as made by the presiding court or arbitrator of competent jurisdiction shall be binding, then both parties agree to substitute such provision(s) through good faith negotiations.
