4

6.                                      CONVERSION.

6.1                               Conversion at Public Offering.  At the Public Offering Closing, the entire Balance then outstanding shall automatically be cancelled and converted into that number of shares of Conversion Stock obtained by dividing (a) the entire Balance by (b) the Conversion Price then in effect.  Such conversion shall be deemed to occur under this Section 6.1 as of immediately prior to the Public Offering Closing, without regard to whether Holder has then delivered to the Company this Note (or the Lost Note Documentation where applicable).

6.2                               Termination of Rights.  Except for the right to obtain certificates representing the Conversion Stock under Section 7, all rights with respect to this Note shall terminate upon the effective conversion of the entire Balance of the Note as provided in Section 2.1 or 6.1, whichever is applicable.  Notwithstanding the foregoing, Holder agrees to surrender this Note to the Company (or Lost Note Documentation where applicable) as soon as practicable after conversion.  In any event, Holder shall not be entitled to receive any stock certificates representing the shares of Conversion Stock issuable upon conversion of this Note unless and until Holder has surrendered the original of this Note (or Lost Note Documentation where applicable).

7.                                      CERTIFICATES; NO FRACTIONAL SHARES.  Subject to Section 6.2, as soon as practicable after conversion of this Note pursuant to Section 2.1 or 6.1, as applicable, the Company at its expense will cause to be issued in the name of Holder and to be delivered to Holder, a certificate or certificates for the number of shares of Conversion Stock to which Holder shall be entitled upon such conversion (bearing such legends as may be required by applicable state and federal securities laws in the opinion of legal counsel of the Company, by any lockup agreement, by the Company’s Certificate of Incorporation and Bylaws and by any agreement between the Company and Holder), together with any other securities and property to which Holder is entitled upon such conversion under the terms of this Note.  No fractional shares shall be issued upon conversion of this Note.  If upon any conversion of this Note a fraction of a share would otherwise be issued, then in lieu of such fractional share, the Company shall pay to Holder an amount in cash equal to such fraction of a share multiplied by the applicable Conversion Price.

8.                                      ADJUSTMENT PROVISIONS.  So long as any of the Balance of this Note remains outstanding and conversion under Sections 2.1 or 6.1 has not occurred, the number and character of shares of Conversion Stock issuable upon conversion of this Note upon an Actual Conversion Date and, to the extent set forth in this Section 8, the Conversion Price therefor, are each subject to adjustment upon each occurrence of an adjustment event described in Sections 8.1 through 8.4 occurring between the date this Note is issued and such Actual Conversion Date.

8.1                               Adjustment for Stock Splits and Stock Dividends.  The Conversion Price and the number of shares of Conversion Stock shall each be proportionally adjusted to reflect any stock dividend, stock split, reverse stock split or other similar event affecting the number of outstanding shares of Conversion Stock without the payment of consideration to the Company therefor at any time before an Actual Conversion Date.

5

8.2                               Adjustment for Other Dividends and Distributions.  If the Company shall make or issue, or shall fix a record date for the determination of eligible holders of its capital stock entitled to receive, a dividend or other distribution payable with respect to the Conversion Stock that is payable in securities of the Company (other than issuances with respect to which adjustment is made under Sections 8.1 or 8.3), or in assets (other than cash dividends) (each, a “Dividend Event”), and such dividend or other distribution is actually made, then, and in each such case, Holder, upon conversion of an Actual Conversion Amount at any time after such Dividend Event, shall receive, in addition to the Conversion Stock issuable upon such conversion of the Note, the securities or other assets that would have been issuable to Holder had Holder, immediately prior to such Dividend Event, converted such Actual Conversion Amount into Conversion Stock.

8.3                               Adjustment for Consolidation or Merger.  If the Company shall consolidate with or merge into one or more other corporations or other entities, and pursuant to such consolidation or merger, stock, other securities or other property is issued or paid to holders of Conversion Stock (each, a “Reorganization Event”), then, and in each such case, Holder, upon conversion of an Actual Conversion Amount after the consummation of such Reorganization Event, shall be entitled to receive (in lieu of the stock or other securities and property that Holder would have been entitled to receive under the terms of this Note upon such conversion but for such Reorganization Event), the stock or other securities or property that Holder would have been entitled to receive upon the consummation of such Reorganization Event if, immediately prior to such Reorganization Event, Holder had converted such Actual Conversion Amount into Conversion Stock, all subject to further adjustment as provided in this Note, and the successor corporation or other successor entity in such Reorganization Event shall duly execute and deliver to Holder a supplement to this Note acknowledging such corporation’s or other entity’s obligations under this Note; and in each such case, the terms of the Note shall be applicable to the shares of stock or other securities or property receivable upon the conversion of this Note after the consummation of such Reorganization Event.

8.4                               Conversion of Stock.  In each case not otherwise covered in Section 8.3 where (a) all the outstanding Conversion Stock is converted, pursuant to the terms of the Company’s Certificate of Incorporation, into Common Stock or other securities or property, or (b) the Conversion Stock otherwise ceases to exist or to be authorized under the Company’s Certificate of Incorporation (each a “Stock Event”), then Holder, upon conversion of this Note at any time after such Stock Event, shall receive, in lieu of the number of shares of Conversion Stock that would have been issuable upon conversion of this Note immediately prior to such Stock Event, the stock and other securities and property that Holder would have been entitled to receive upon the Stock Event, if immediately prior to such Stock Event, Holder had converted the Actual Conversion Amount into Conversion Stock.

8.5                               Notice of Adjustments.  The Company shall promptly give written notice of each adjustment of the Conversion Price or the number or type of shares of Conversion Stock or other securities or property issuable upon conversion of this Note that is required under this Section 8.  The notice shall describe the adjustment or readjustment and show in reasonable detail the facts on which the adjustment or readjustment is based.

6

8.6                               No Change Necessary.  The form of this Note may, but need not, be changed because of any adjustment in the Conversion Price or in the number or type of shares of Conversion Stock issuable upon its conversion.

8.7                               Reservation of Stock.  If the number of shares of Conversion Stock or other securities authorized and reserved for issuance upon conversion of this Note shall not be sufficient to effect the conversion of the Balance of this Note, then the Company shall take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Conversion Stock or other securities issuable upon conversion of this Note as shall be sufficient for such purpose.

9.                                      PROVISIONS RELATING TO STOCKHOLDERS RIGHTS.

9.1                               Rights as Investor.  Upon conversion of the Balance in connection with the Public Offering, Holder shall be entitled to the rights and be subject to all other obligations of the investors in the Conversion Stock issued in the Public Offering.

“Market Stand-Off” Agreement.  Holder hereby agrees that Holder shall not, to the extent requested by the Company or an underwriter of securities of the Company, sell or otherwise transfer or dispose of any shares of stock or other securities of the Company then or thereafter owned by Holder (other than to donees or partners of Holder who agree to be similarly bound) for up to one hundred eighty (180) days, plus up to an additional 18 days to the extent necessary to comply with applicable regulatory requirements, following the effective date of a registration statement of the Company filed under the Securities Act; provided, however, that such agreement shall be applicable only to the first such registration statement of the Company which covers securities to be sold on its behalf to the public in an underwritten offering, but shall not apply to any securities sold pursuant to such registration statement.

For purposes of this Section 9.2, the term “Company” shall include any wholly-owned subsidiary of the Company into which the Company merges or consolidates.  In order to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the certificates representing the securities of the Company subject to this Section and to impose stop transfer instructions with respect to the securities of the Company held by Holder (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period.  Holder further agrees to enter into any agreement reasonably required by the underwriters to implement the foregoing within any reasonable timeframe so requested.

9.2                               No Voting or Other Rights.  This Note does not entitle Holder to any voting rights or other rights as a stockholder of the Company, unless and until (and only to the extent that) this Note is actually converted into shares of the Company’s capital stock in accordance with its terms.  In the absence of conversion of this Note into Conversion Stock, no provisions of this Note and no enumeration herein of the rights or privileges of Holder, shall cause Holder to be a stockholder of the Company for any purpose.

7

9.3          Inspection Rights.  Holder shall also be entitled to standard inspection and visitation rights pursuant to Delaware law.

10.          REPRESENTATIONS AND WARRANTIES OF HOLDER.

In order to induce the Company to issue this Note to the original Holder, the original Holder has made representations and warranties to the Company as set forth below.

10.1        Authorization.  This Note constitutes Holder’s valid and legally binding obligations, enforceable against Holder in accordance with its terms, except as may be limited by  (i) applicable bankruptcy, insolvency, reorganization or other laws of general application relating to or affecting the enforcement of creditors’ rights generally and (ii) the effect of rules of law governing the availability of equitable remedies.  Holder represents and warrants to the Company that Holder has full power and authority to enter into this Note.

10.2        Purchase for Own Account.  The Note and the Conversion Stock issuable upon the conversion of the Note, (collectively, the “Securities”) will be acquired for investment for Holder’s own account, not as a nominee or agent, and not with a view to the public resale or distribution thereof within the meaning of the Securities Act, and Holder has no present intention of selling, granting any participation in, or otherwise distributing the same.

10.3        No Solicitation.  At no time was Holder presented with or solicited by any publicly issued or circulated newspaper, mail, radio, television or other form of general advertising or solicitation in connection with the offer, sale and purchase of the Securities.

10.4        Disclosure of Information.  Holder has received or has had full access to all the information Holder considers necessary or appropriate to make an informed investment decision with respect to the Securities.  Holder further has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Securities and to obtain additional information (to the extent the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any information furnished to Holder or to which Holder had access.

10.5        Investment Experience.  Holder understands that the purchase of the Securities involves substantial risk.  Holder (i) has experience as an investor in securities of companies in the development stage and acknowledges that such Investor is able to fend for itself, can bear the economic risk of Holder’s investment in the Securities and has such knowledge and experience in financial or business matters that Holder is capable of evaluating the merits and risks of this investment in the Securities and protecting Holder’s own interests in connection with this investment in the Securities or (ii) has a preexisting personal or business relationship with the Company and certain of its officers, directors or controlling persons of a nature and duration that enables Holder to be aware of the character, business acumen and financial circumstances of such persons.

10.6        Accredited Investor Status.  Holder is familiar with the definition of, and qualifies as, an “accredited investor” within the meaning of Regulation D promulgated under the Securities Act.

8

10.7        Restricted Securities.  Holder understands that the Securities are characterized as “restricted securities” under the Securities Act and Rule 144 promulgated thereunder (“Rule 144”) since they are being acquired from the Company in a transaction not involving a public offering, and that under the Securities Act and applicable regulations thereunder the Securities may be resold without registration under the Securities Act only in certain limited circumstances.  Holder further understands that the Company is under no obligation to register the Securities, and the Company has no present plans to do so.  Furthermore, Holder is familiar with Rule 144, as presently in effect, and understands the limitations imposed thereby and by the Securities Act on resale of the Securities without such registration.  Holder understands that, whether or not the Securities may be resold in the future without registration under the Securities Act, no public market now exists for any of the Securities and that it is uncertain whether a public market will ever exist for the Securities.

10.8        Further Limitations on Disposition.  Without in any way limiting the representations set forth above, Holder further agrees not to make any disposition of all or any portion of the Securities unless and until:

(a)           there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such effective registration statement; or

(b)           Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a statement of the circumstances surrounding the proposed disposition and, at the expense of Holder or its transferee, with an opinion of counsel reasonably satisfactory in form and substance to the Company that such disposition will not require registration of such Securities under the Securities Act.

Notwithstanding the provisions of paragraphs (a) and (b) of this Section 10.8, no such registration statement or opinion of counsel shall be required for any transfer:  (i) of any Securities in compliance with Rule 144 or Rule 144A promulgated under the Securities Act when the Company is promptly provided evidence of such compliance; (ii) of any Securities by a Holder that is a partnership or a corporation to (A) a partner of such partnership or stockholder of such corporation, (B) an affiliate of such partnership or corporation, (C) a retired partner of such partnership who retires after the date hereof, (D) the estate of any deceased partner of such partnership or deceased stockholder of such corporation; or (iii) by gift, will or intestate succession by any Holder to his or her spouse or lineal descendants or ancestors or any trust for any of the foregoing; provided that in each of the foregoing cases the transferee agrees in writing to be subject to the terms of this Section 10.8 to the same extent as if the transferee had been an original Holder hereunder.

10.9        Legends.  Holder understands and agrees that the certificates evidencing the Securities will bear legends substantially similar to those set forth below in addition to any other legend that may be required by applicable law, the Company’s Certificate of Incorporation or Bylaws, Section 9.2 above or any other agreement between the Company and Holder:

(a)           THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE

9

“ACT”), OR UNDER THE SECURITIES LAWS OF APPLICABLE STATES.  THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION UNDER SUCH LAWS OR AN EXEMPTION FROM SUCH REGISTRATION REQUIREMENT.  INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME.  THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND ALL APPLICABLE STATE SECURITIES LAWS.

(b)           Any legend pursuant to a lock up agreement, required by the laws of the State of California, including any legend required by the California Department of Corporations or any other state securities laws.

The legend set forth in (a) above shall be removed by the Company from any certificate evidencing the Securities upon delivery to the Company of an opinion of counsel, reasonably satisfactory in form and substance to the Company, that either (i) a registration statement under the Securities Act is at that time in effect with respect to the legended security or (ii) such security can be freely transferred in a public sale (other than pursuant to Rule 144, Rule 144A or Rule 145 promulgated under the Securities Act) without such a registration statement being in effect and that such transfer will not jeopardize the exemption or exemptions from registration pursuant to which the Company issued the Securities.

10.10      Disqualification.  Holder represents that neither Holder, nor any person or entity with whom Holder shares beneficial ownership of the Company securities, is subject to any Disqualification Event (as defined in Rule 506(d)(1)(i) through (viii) under the Securities Act), except for Disqualification Events covered by Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Securities Act and disclosed reasonably in advance of the date hereof in writing in reasonable detail to the Company.

11.          GENERAL PROVISIONS.

11.1        Waivers.  The Company and all endorsers of this Note hereby waive notice, presentment, protest and notice of dishonor.

11.2        Attorneys’ Fees.  In the event any party is required to engage the services of an attorney for the purpose of enforcing this Note, or any provision thereof, the prevailing party shall be entitled to recover its reasonable expenses and costs in enforcing this Note, including attorneys’ fees.

11.3        Transfer.  Neither this Note nor any rights hereunder may be assigned, conveyed or transferred, in whole or in part, without the Company’s prior written consent, which the Company may withhold in its sole discretion.  Subject to the foregoing, the rights and obligations of the Company and Holder under this Note shall be binding upon and benefit their respective permitted successors, assigns, heirs, administrators and transferees.

10

11.4        Governing Law.  This Note shall be governed by and construed under the internal laws of the State of California as applied to agreements among California residents entered into and to be performed entirely within the State of California, without reference to principles of conflict of laws or choice of laws.

11.5        Headings.  The headings and captions used in this Note are used only for convenience and are not to be considered in construing or interpreting this Note.  All references in this Note to sections and exhibits shall, unless otherwise provided, refer to sections hereof and exhibits attached hereto, all of which exhibits are incorporated herein by this reference.
