3. Payment and Exercise.

(a) Methods of Exercise. The purchase right represented by this Warrant may be exercised by the Holder, in whole or in part and from time to time, at the election of the Holder, by (a) the surrender of this Warrant (with the notice of exercise substantially in the form attached hereto as Exhibit A duly completed and executed) at the principal office of the Company and by the payment to the Company, by check, or by wire transfer to an account designated by the Company of an amount equal to the then applicable Exercise Price multiplied by the number of Shares then being purchased (the “Aggregate Purchase Price”); (b) if in connection with a registered public offering of the Company’s securities, the surrender of this Warrant (with the notice of exercise form attached hereto as Exhibit B duly completed and executed) at the principal office of the Company together with notice of arrangements reasonably satisfactory to the Company for payment to the Company from the proceeds of the sale of shares to be sold by the Holder in such public offering of the Aggregate Purchase Price; or (c) exercise of the “net issuance” right provided for in Section 3(b) hereof. The person or persons in whose name(s) any certificate(s) representing Shares of Applicable Stock shall be issuable upon exercise of this Warrant shall be deemed to have become the holder(s) of record of, and shall be treated for all purposes as the record holder(s) of, the Shares represented thereby (and such Shares shall be deemed to have been issued) immediately prior to the close of business on the date or dates upon which this Warrant is exercised. In the event of any exercise of the rights represented by this Warrant, certificates for the Shares so purchased shall be delivered to the Holder as soon as possible and in any event within thirty (30) days after such exercise and, unless this Warrant has been fully exercised or expired, a new Warrant representing the portion of the Shares, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder as soon as possible and in any event within such thirty-day period; provided, however, that at such time as the Company is subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, if requested by the Holder, the Company shall cause its transfer agent to deliver the certificate representing Shares issued upon exercise of this Warrant to a broker or other person (as directed by the Holder exercising this Warrant) within the time period required to settle any trade made by the Holder after exercise of this Warrant.

(b) Right to Convert Warrant into Stock: Net Issuance.

-2-

time or from time to time during the term of this Warrant. Upon exercise of the Net Issuance Right with respect to a particular number of shares subject to this Warrant (the “Converted Warrant Shares”), the Company shall deliver to the Holder (without payment by the Holder of any exercise price or any cash or other consideration) that number of shares of fully paid and nonassessable Applicable Stock as is determined according to the following formula:


X	=	A - B
		Y


Where: X	=	the number of shares of Applicable Stock that shall be issued to Holder

Y	=	the fair market value of one share of Applicable Stock

A	=	the aggregate fair market value of the specified number of Converted Warrant Shares (i.e., the number of Converted Warrant Shares multiplied by the fair market value of one Converted Warrant Share)

B	=	the aggregate Exercise Price of the specified number of Converted Warrant Shares immediately prior to the exercise of the Net Issuance Right (i.e., the number of Converted Warrant Shares multiplied by the Exercise Price)

No fractional shares shall be issuable upon exercise of the Net Issuance Right, and, if the number of shares to be issued determined in accordance with the foregoing formula is other than a whole number, the Company shall pay to the Holder an amount in cash equal to the fair market value of the resulting fractional share on the Conversion Date (as hereinafter defined). For purposes of Section 10 of this Warrant, shares issued pursuant to the Net Issuance Right shall be treated as if they were issued upon the exercise of this Warrant.

(ii) Exercise of Net Issuance Right. The Net Issuance Right may be exercised by the Holder by the surrender of this Warrant at the principal office of the Company together with a written statement (which may be in the form of Exhibit A or Exhibit B hereto) specifying that the Holder thereby intends to exercise the Net Issuance Right and indicating the number of shares subject to this Warrant which are being surrendered (referred to in Section 3(b)(i) hereof as the Converted Warrant Shares) in exercise of the Net Issuance Right. Such conversion shall be effective upon receipt by the Company of this Warrant together with the aforesaid written statement, or on such later date as is specified therein (the “Conversion Date”), and, at the election of the Holder, may be made contingent upon the closing of the sale of the Company’s Common Stock to the public in a public offering (a “Public Offering”) pursuant to a Registration Statement under the Securities Act of 1933, amended (the “Act”). Certificates for the shares issuable upon exercise of the Net Issuance Right and, if applicable, a new warrant evidencing the balance of the shares remaining subject to this Warrant, shall be issued as of the Conversion Date and shall be delivered to the Holder within thirty (30) days following the Conversion Date.

(iii) Determination of Fair Market Value. For purposes of this Section 3(b), “fair market value” of a share of Applicable Stock (which shall be Common Stock if the Applicable Stock has been converted into Common Stock) as of a particular date (the “Determination Date”) shall mean:

(1) If the Net Issuance Right is exercised in connection with and contingent upon a Public Offering, and if the Company’s Registration Statement relating to such Public Offering (“Registration Statement”) has been declared effective by the Securities and Exchange Commission, then the initial “price to the public” specified in the final prospectus with respect to such offering.

(2) If the Net Issuance Right is not exercised in connection with and contingent upon a Public Offering, then as follows:

-3-

(A) If traded on a securities exchange, then the fair market value shall be the average of the closing prices of the Common Stock on such exchange over the five trading days immediately prior to the Determination Date;

(B) If traded on the Nasdaq Stock Market or other over-the-counter system, then the fair market value shall be the average of the closing bid prices of the Common Stock over the five trading days immediately prior to the Determination Date; and

(C) If there is no public market, then fair market value shall be determined in good faith by the Company’s Board of Directors.

In making a determination under clauses (A) or (B) above, if on the Determination Date, five trading days have not passed since the Company’s initial Public Offering then the fair market value of the Common Stock shall be the average closing prices or closing bid prices, as applicable, for the shorter period beginning on and including the date of the initial Public Offering and ending on the trading day prior to the Determination Date (or if such period includes only one trading day the closing price or closing bid price, as applicable, for such trading day). If closing prices or closing bid prices are no longer reported by a securities exchange or other trading system, the closing price or closing bid price shall be that which is reported by such securities exchange or other trading system at 4:00 p.m. New York City time on the applicable trading day.

(c) Exercise Prior to Expiration. To the extent this Warrant is not previously exercised as to all of the Shares subject hereto, and if the fair market value of one share of the Applicable Stock is greater than the Exercise Price then in effect, this Warrant shall be deemed automatically exercised pursuant to Section 3(b) (even if not surrendered) immediately before its expiration, including but not limited to expiration pursuant to Section 2. For purposes of such automatic exercise, the fair market value of one share of the Applicable Stock upon such expiration shall be determined pursuant to Section 3(b)(iii). To the extent this Warrant or any portion thereof is deemed automatically exercised pursuant to this Section 3(c), the Company agrees to promptly notify the Holder of the number of Shares, if any, the Holder is to receive by reason of such automatic exercise.

4. Stock Fully Paid; Reservation of Shares. All Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance pursuant to the terms and conditions herein, be fully paid and nonassessable, and free from all preemptive rights and taxes, liens and charges with respect to the issuance thereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of its Applicable Stock to provide for the exercise of the rights represented by this Warrant and, while the Applicable Stock is convertible preferred stock, a sufficient number of shares of its Common Stock to provide for the conversion of the Applicable Stock into Common Stock.

5. Adjustment of Exercise Price and Number of Shares. The number and kind of securities purchasable upon the exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a) Reclassification or Merger. In case of any reclassification or change of securities of the class issuable upon exercise of this Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), the Company shall duly execute and deliver to the Holder a new Warrant (in form and substance satisfactory to the Holder), or the Company shall make appropriate provision without the issuance of a new Warrant, so that the Holder shall have the right to receive upon exercise of this Warrant, at a total purchase price not to exceed that payable upon the exercise of the unexercised portion of this Warrant, and in lieu of the shares of Applicable Stock theretofore issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such reclassification or change by a holder of the number of

-4-

shares of Applicable Stock then purchasable under this Warrant. The provisions of this Section 5(a) shall similarly apply to successive reclassifications and changes.

(b) Subdivision or Combination of Shares. If the Company at any time while this Warrant remains outstanding and unexpired shall subdivide or combine its outstanding shares of Applicable Stock, the Exercise Price shall be proportionately decreased and the number of Shares issuable hereunder shall be proportionately increased in the case of a subdivision and the Exercise Price shall be proportionately increased and the number of Shares issuable hereunder shall be proportionately decreased in the case of a combination.

(c) Stock Dividends and Other Distributions. If the Company at any time while this Warrant is outstanding and unexpired shall (i) pay a dividend with respect to Applicable Stock payable in Applicable Stock, then the Exercise Price shall be adjusted, from and after the date of determination of shareholders entitled to receive such dividend or distribution, to that price determined by multiplying the Exercise Price in effect immediately prior to such date of determination by a fraction (A) the numerator of which shall be the total number of shares of Applicable Stock outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of Applicable Stock outstanding immediately after such dividend or distribution; or (ii) make any other distribution with respect to Applicable Stock (except any distribution specifically provided for in Sections 5(a) and 5(b)), then, in each such case, provision shall be made by the Company such that the Holder shall receive upon exercise of this Warrant a proportionate share of any such dividend or distribution as though it were the holder of the Applicable Stock as of the record date fixed for the determination of the shareholders of the Company entitled to receive such dividend or distribution.

(d) Adjustment of Number of Shares. Upon each adjustment in the Exercise Price, the number of Shares of Applicable Stock purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying the number of Shares purchasable immediately prior to such adjustment in the Exercise Price by a fraction, the numerator of which shall be the Exercise Price immediately prior to such adjustment and the denominator of which shall be the Exercise Price immediately thereafter.

(e) Antidilution Rights. The other antidilution rights applicable to the Shares of Applicable Stock purchasable hereunder are set forth in the Company’s Certificate of Incorporation, as amended through the Warrant Date, a true and complete copy of which is attached hereto as Exhibit C (the “Charter”). The Company shall promptly provide the Holder with any restatement, amendment, modification or waiver of the Charter promptly after the same has been made.

6. Notice of Adjustments. Whenever the Exercise Price or the number of Shares purchasable hereunder shall be adjusted pursuant to Section 5 hereof, the Company shall make a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the Exercise Price and the number of Shares purchasable hereunder after giving effect to such adjustment, and shall cause copies of such certificate to be delivered to the Holder. In addition, whenever the conversion price or conversion ratio of the Applicable Stock shall be adjusted, the Company shall make a certificate signed by its chief financial officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the conversion price or ratio of the Applicable Stock after giving effect to such adjustment, and shall cause copies of such certificate to be delivered to the Holder.

7. Fractional Shares. No fractional shares of Applicable Stock will be issued in connection with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefor based on the fair market value of the Applicable Stock on the date of exercise as reasonably determined in good faith by the Company’s Board of Directors.

8. Compliance with Act; Disposition of Warrant or Shares of Applicable Stock.

-5-

(a) Compliance with Act. The Holder, by acceptance hereof, agrees that this Warrant, and the shares of Applicable Stock to be issued upon exercise hereof and any Common Stock issued upon conversion thereof are being acquired for investment and that the Holder will not offer, sell or otherwise dispose of this Warrant, or any shares of Applicable Stock to be issued upon exercise hereof or any Common Stock issued upon conversion thereof except under circumstances which will not result in a violation of the Act or any applicable state securities laws. Upon exercise of this Warrant, unless the Shares being acquired are registered under the Act and any applicable state securities laws or an exemption from such registration is available, the Holder shall confirm in writing that the shares of Applicable Stock so purchased (and any shares of Common Stock issued upon conversion thereof) are being acquired for investment and not with a view toward distribution or resale in violation of the Act and shall confirm such other matters related thereto as may be reasonably requested by the Company. This Warrant and all shares of Applicable Stock issued upon exercise of this Warrant (unless registered under the Act and any applicable state securities laws) shall be stamped or imprinted with a legend in substantially the following form:

“THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. NO SALE OR DISPOSITION MAY BE EFFECTED WITHOUT (i) EFFECTIVE REGISTRATION STATEMENTS RELATED THERETO, (ii) AN OPINION OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATIONS ARE NOT REQUIRED, (iii) RECEIPT OF NO-ACTION LETTERS FROM THE APPROPRIATE GOVERNMENTAL AUTHORITIES, OR (iv) OTHERWISE COMPLYING WITH THE PROVISIONS OF SECTION 8 OF THE WARRANT UNDER WHICH THESE SECURITIES WERE ISSUED, DIRECTLY OR INDIRECTLY.”

Said legend shall be removed by the Company, upon the request of the Holder, at such time as the restrictions on the transfer of the applicable security shall have terminated.

(b) Disposition of Warrant or Shares. With respect to any offer, sale or other disposition of this Warrant or any shares of Applicable Stock acquired pursuant to the exercise of this Warrant prior to registration of such Warrant or shares, the Holder agrees to give written notice to the Company prior thereto, describing briefly the manner thereof, together with a written opinion of counsel, if requested by the Company, or other evidence, if reasonably satisfactory to the Company, to the effect that such offer, sale or other disposition may be effected without registration or qualification (under the Act as then in effect or any federal or state securities law then in effect) of this Warrant or such shares of Applicable Stock and indicating whether or not under the Act certificates for this Warrant or such shares of Applicable Stock to be sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to ensure compliance with such law. Upon receiving such written notice and reasonably satisfactory opinion or other evidence, the Company shall have the right to consent to such transfer, which shall not be unreasonably withheld (except with respect to any transfer to any affiliate of the Holder, in which case no consent shall be required) (any such transfer as to which no consent is required or consent has been granted, a “Permitted Transfer”), and shall, as promptly as practicable but no later than fifteen (15) days after receipt of the written notice, shall notify the Holder whether the Holder may sell or otherwise dispose of this Warrant or such shares of Applicable Stock, all in accordance with the terms of the notice delivered to the Company. If a determination has been made pursuant to this Section 8(b) that the opinion of counsel or other evidence is not reasonably satisfactory to the Company, the Company shall so notify the Holder promptly with details thereof after such determination has been made. Notwithstanding the foregoing, but subject to the right of the Company to consent, if applicable, this Warrant or such shares of Applicable Stock may, as to such federal laws, be offered, sold or otherwise disposed of in accordance with Rule 144 or 144A under the Act, 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 or 144A have been satisfied. Each certificate representing this Warrant or the shares of Applicable Stock thus transferred (except a transfer pursuant to Rule 144 or 144A) shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with such laws, unless in the aforesaid opinion of counsel for the Holder, such legend is not required in order to ensure compliance with such laws. The Company may issue stop transfer instructions to its transfer agent in connection with such restrictions.

-6-

(c) Applicability of Restrictions. Neither any restrictions of any legend described in this Warrant nor the requirements of Section 8(b) above shall apply to any transfer of, or grant of a security interest in, this Warrant (or the Applicable Stock or Common Stock obtainable upon exercise thereof) or any part hereof (i) to a partner of the Holder if the Holder is a partnership or to a member of or other holder of an interest in the Holder if the Holder is a limited liability company, (ii) to a partnership of which the Holder is a partner or to a limited liability company of which the Holder is a member or other holder of an interest, or (iii) to any affiliate of the Holder if the Holder is a corporation; provided, however, in any such transfer, if applicable, the transferee shall on the Company’s request agree in writing to be bound by the terms of this Warrant as if an original holder hereof.

9. Rights as Shareholders; Information. No Holder, as a holder of this Warrant, shall be entitled to vote or receive dividends or be deemed the holder of Applicable Stock or any other securities of the Company which may at any time be issuable upon the exercise hereof 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 receive dividends or subscription rights or otherwise until this Warrant shall have been exercised and the Shares purchasable upon the exercise hereof shall have become deliverable, as provided herein. Notwithstanding the foregoing, the Company will transmit to the Holder such information, documents and reports as are generally distributed to the holders of any class or series of the securities of the Company concurrently with the distribution thereof to the shareholders.

10. Registration Rights. In connection with the closing of its next round of equity financing, the Company shall amend that certain Registration Rights Agreement dated as [March 10, 2006, amended on May 12, 2006 and September 21, 2006], (the “Investor Rights Agreement”) to grant registration rights to the Holder for any Applicable Stock of the Company (after its conversion to Common Stock) obtained upon exercise of this Warrant, comparable to the registration rights granted to the investors in the Investor Rights Agreement, with the following exceptions and clarifications:

(1) The Holder will have not have the right to demand registration (other than a registration on Form S-3 or any successor form), but can otherwise participate in any registration demanded by others.

(2) The Holder will be subject to the same provisions regarding indemnification as contained in the Investor Rights Agreement.

(3) The registration rights are freely assignable by the Holder in connection with a Permitted Transfer of this Warrant or the Shares.

(4) Any underwriter’s “cut back” shall first apply to the rights of the Holder with respect to shares issued upon the exercise of this Warrant and then to the rights of other holders of the Company’s preferred stock (including the Holder with respect to any shares of preferred stock held other than as a result of the exercise of this Warrant).

11. Notice Rights.

(a) Acquisition Transactions. The Company shall provide the Holder with at least ten (10) days’ written notice prior to closing thereof of the terms and conditions of any of the following transactions (to the extent the Company has notice thereof): (i) the sale, lease, exchange, conveyance or other disposition of all or substantially all of the Company’s property or business, or (ii) its merger into or consolidation with any other corporation (other than a wholly-owned subsidiary of the Company), or any transaction (including a merger or other reorganization) or series of related transactions, in which more than 50% of the voting power of the Company is disposed of.
