2.    EXERCISE.
2.1    Method of Exercise.  Subject to the terms and conditions of this Warrant, Holder may exercise this Warrant in whole or in part, at any time or from time to time, on any Business Day before the earlier of: (i) the Expiration Date, (ii) the occurrence of a Deemed Liquidation Event or (iii) an Initial Public Offering, for up to that number of shares of Warrant Stock that is obtained by dividing the Purchase Amount by the then effective Warrant Price.  This Warrant shall be exercised by surrendering this Warrant at the principal offices of the Company, with the subscription form attached hereto duly executed by Holder, and by payment in a form specified in Section 2.2 of an amount equal to the product obtained by multiplying (i) the number of shares of Warrant Stock to be purchased by Holder by (ii) the Warrant Price as determined in accordance with the terms hereof or, if applicable, an election to net exercise the Warrant as provided in Section 2.6 for the number of shares to be acquired in connection with such exercise. Holder may deliver the subscription form attached hereto duly executed by Holder in order to exercise this Warrant in connection with an Initial Public Offering or a Deemed Liquidation Event, with the exercise and payment to be contingent upon consummation of the transaction.
2.2    Form of Payment.  Payment for the Warrant Stock upon exercise may be made by (a) a check payable to the Company’s order, (b) wire transfer of funds to the Company, (c) cancellation of indebtedness of the Company to Holder, (d) by net exercise as provided in Section 2.6, or (e) any combination of the foregoing.  
2.3    Partial Exercise.  Upon a partial exercise of this Warrant: (a) the Purchase Amount immediately prior to such partial exercise shall be reduced by the aggregate Purchase Amount of such partial exercise, and (b) this Warrant shall be cancelled and replaced with a new Warrant of like tenor in which the stated Purchase Amount is the Purchase Amount as so reduced.  
2.4    No Fractional Shares.  No fractional shares may be issued upon any exercise of this Warrant.  If upon exercise of this Warrant in whole or in part, a fraction of a share would otherwise result, 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 Warrant Price.
2.5    Restrictions on Exercise.  As a condition to the exercise of this Warrant, Holder shall execute the subscription form attached hereto as Exhibit 1, confirming and acknowledging that the representations and warranties of the original Holder set forth in Section 4 of the Purchase Agreement are true and complete as of the date of exercise.
2.6    Net Exercise Election.
2.6.1    Holder may elect to convert all or any portion, of this Warrant, without the payment by Holder of any additional consideration, by the surrender of this Warrant to the Company, with the net exercise election selected in the subscription form attached hereto, duly executed by Holder, into up to the number of shares of Warrant Stock that is obtained under the following formula:
X = Y (A-B) 
    A

3

		
	where
	X  =    the number of shares of Warrant Stock to be issued to Holder pursuant to a net exercise of this Warrant effected pursuant to this Section 2.6.

		
	Y  =
	the Purchase Amount divided by the Warrant Price.

		
	A  =
	the fair market value of one share of Warrant Stock, determined at the time of such net exercise as set forth in the last paragraph of this Section 2.6.

		
	B  =
	the Warrant Price.

The Company will promptly respond in writing to an inquiry by Holder as to the then current fair market value of one share of Warrant Stock.
2.6.2    For purposes of the above calculation, fair market value of one share of Warrant Stock shall be determined by the Company’s Board of Directors in good faith; provided, however, that if on the relevant exercise date for which such value must be determined, then the fair market value per share of the Warrant Stock shall be the per-share offering price to the public as set forth in the Company’s final prospectus filed with the Securities and Exchange Commission.
3.    ISSUANCE OF STOCK.  Except as set forth in Section 4, this Warrant shall be deemed to have been exercised immediately prior to the close of business on the date of its surrender for exercise as provided above, and the person entitled to receive the shares of Warrant Stock issuable upon such exercise shall be treated for all purposes as the holder of record of such shares as of the close of business on such date.  As soon as practicable on or after such date, the Company shall issue and deliver to the person or persons entitled to receive the same a certificate or certificates for the number of whole shares of Warrant Stock issuable upon such exercise, together with payment of any fractional shares pursuant to Section 2.4.
4.    EXERCISES IN CONNECTION WITH CERTAIN TRANSACTIONS.  If the Company proposes at any time to effect a Deemed Liquidation Event or an Initial Public Offering, the Company shall give the Holder at least ten (10) days advance written notice (each, a “Transaction Notice”) of the anticipated closing date for such Deemed Liquidation Event or the anticipated initial closing date for such Initial Public Offering, as applicable.
If pursuant to a Transaction Notice, Holder has not elected to exercise this Warrant under Section 2 in connection with a Deemed Liquidation Event or an Initial Public Offering, then upon the effective date of the Deemed Liquidation Event or the initial closing of the Initial Public Offering, this Warrant shall automatically be deemed net exercised in full pursuant to Section 2.6 above.
5.    ADJUSTMENT PROVISIONS.  The number and character of shares of Warrant Stock issuable upon exercise of this Warrant and the Warrant Price therefor, are subject to adjustment upon each event in Sections 5.1 through 5.4 occurring between the date this Warrant is issued and earlier of the time that it is exercised in full or the Expiration Date:  
5.1    Adjustment for Stock Splits and Stock Dividends, Etc.. If the Company declares or pays a dividend or distribution on the outstanding shares of the Warrant Stock payable in Common Stock or other securities or property (other than cash), then upon exercise of this Warrant, for each share of Warrant Stock acquired, Holder shall receive, without additional cost to Holder, the total number and kind of securities and property which Holder would have received had Holder owned the shares of Warrant Stock of record as of the date the dividend or distribution occurred. If the Company subdivides the outstanding shares of Warrant Stock by reclassification or otherwise into a greater number

4

of shares, the number of shares of Warrant Stock purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased.  If the outstanding shares of Warrant Stock are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased and the number of shares of Warrant Stock shall be proportionately decreased.
5.2    Adjustment for Other Dividends and Distributions.  In case the Company shall make or issue, or shall fix a record date for the determination of eligible holders entitled to receive a dividend or other distribution payable with respect to the Warrant Stock that is payable in (a) securities of the Company (other than issuances with respect to which adjustment is made under Section 5.1 or Section 5.3) or (b) assets (other than cash) which dividend or distribution is actually made (each a “Dividend Event”), then, and in each such case, Holder, upon exercise of this Warrant at any time after such Dividend Event, shall receive, in addition to the shares of Warrant Stock, the securities or such other assets of the Company that would have been payable to Holder if Holder had completed such exercise of this Warrant, immediately prior to such Dividend Event.  
5.3    Adjustment for Reorganization, Consolidation, Merger.  (a) In case of any recapitalization or reorganization of the Company or (b) in case the Company shall consolidate with or merge into one or more other corporations or entities which results in a change of the Warrant Stock (each, a “Reorganization Event”), then, and in each such case, Holder, upon the exercise of this Warrant after 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 upon such exercise prior to such Reorganization Event, the stock or other securities or property which Holder would have been entitled to receive upon such Reorganization Event if, immediately prior to such Reorganization Event, Holder had completed such exercise of this Warrant, all subject to further adjustment as provided in this Warrant.  If after such Reorganization Event, the Warrant is exercisable for securities of a corporation or entity other than the Company, then such corporation or entity shall duly execute and deliver to Holder a supplement hereto acknowledging such corporation’s or other entity’s obligations under this Warrant; and in each such case, the terms of this Warrant shall be applicable to the shares of stock or other securities or property receivable upon the exercise of this Warrant after the consummation of such Reorganization Event.
5.4    Conversion of Stock.  In case all (a) the authorized Warrant Stock is converted, pursuant to the Company’s Certificate of Incorporation, into Common Stock or other securities or property, or (b) the Warrant Stock otherwise ceases to exist or to be authorized by the Company’s Certificate of Incorporation (each, a “Stock Event”), then Holder, upon exercise of this Warrant at any time after such Stock Event, shall receive, in lieu of the number of shares of Warrant Stock that would have been issuable upon exercise of this Warrant 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 completed such exercise of this Warrant.
5.5    Notice of Adjustments.  Upon the occurrence of each adjustment or readjustment or the Warrant Price or the number of shares of Warrant Stock or other securities issuable upon the exercise of this Warrant, the Company, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and shall promptly give written notice to the Holder of each adjustment under Section 5 of the Warrant Price or the number of shares of Warrant Stock or other securities that remain issuable upon exercise of this Warrant.  The notice shall describe the adjustment and show in reasonable detail the facts on which the adjustment or readjustment is based.
5.6    No Change Necessary.  The form of this Warrant need not be changed because of any adjustment in the Warrant Price or in the number of shares of Warrant Stock issuable upon its exercise.

5

5.7    Reservation of Stock.  If the number of shares of Warrant Stock or other securities issuable upon exercise of this Warrant that are authorized and unissued under the Company’s Certificate of Incorporation shall not be sufficient to effect the exercise of this Warrant in full, the Company will promptly take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Warrant Stock or other securities issuable upon exercise of this Warrant as shall be sufficient for such purpose.  
6.    NO IMPAIRMENT.  The Company will not, by amendment of its Certificate of Incorporation or bylaws, or through reorganization, consolidation, merger, dissolution, issue or sale of securities, sale of assets or any other voluntary action, willfully avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the holder against wrongful impairment.  Without limiting the generality of the foregoing, the Company will take all such action as may be necessary or appropriate in order that the Company may duly and validly issue fully paid and nonassessable shares of Warrant Stock upon the exercise of this Warrant.

2.    EXERCISE.
2.1    Method of Exercise. Subject to the terms and conditions of this Warrant, Holder may exercise this Warrant in whole or in part, at any time or from time to time, on any Business Day before the earlier of: (i) the Expiration Date, (ii) the occurrence of a Deemed Liquidation Event or (iii) an Initial Public Offering, for up to that number of shares of Warrant Stock that is obtained by dividing the Purchase Amount by the then effective Warrant Price. This Warrant shall be exercised by surrendering this Warrant at the principal offices of the Company, with the subscription form attached hereto duly executed by Holder, and by payment in a form specified in Section 2.2 of an amount equal to the product obtained by multiplying (i) the number of shares of Warrant Stock to be purchased by Holder by (ii) the Warrant Price as determined in accordance with the terms hereof or, if applicable, an election to net exercise the Warrant as provided in Section 2.6 for the number of shares to be acquired in connection with such exercise. Holder may deliver the subscription form attached hereto duly executed by Holder in order to exercise this Warrant in connection with an Initial Public Offering or a Deemed Liquidation Event, with the exercise and payment to be contingent upon consummation of the transaction.
2.2    Form of Payment. Payment for the Warrant Stock upon exercise may be made by (a) a check payable to the Company’s order, (b) wire transfer of funds to the Company, (c) cancellation of indebtedness of the Company to Holder, (d) by net exercise as provided in Section 2.6, or (e) any combination of the foregoing.
2.3    Partial Exercise. Upon a partial exercise of this Warrant: (a) the Purchase Amount immediately prior to such partial exercise shall be reduced by the aggregate Purchase Amount of such partial exercise, and (b) this Warrant shall be cancelled and replaced with a new Warrant of like tenor in which the stated Purchase Amount is the Purchase Amount as so reduced.
2.4    No Fractional Shares. No fractional shares may be issued upon any exercise of this Warrant. If upon exercise of this Warrant in whole or in part, a fraction of a share would otherwise result, 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 Warrant Price.
2.5    Restrictions on Exercise. As a condition to the exercise of this Warrant, Holder shall execute the subscription form attached hereto as Exhibit 1, confirming and acknowledging that the representations and warranties of the original Holder set forth in Section 4 of the Purchase Agreement are true and complete as of the date of exercise.

2.6    Net Exercise Election.
2.6.1    Holder may elect to convert all or any portion, of this Warrant, without the payment by Holder of any additional consideration, by the surrender of this Warrant to the Company, with the net exercise election selected in the subscription form attached hereto, duly executed by Holder, into up to the number of shares of Warrant Stock that is obtained under the following formula:
	
		
	X =
	 Y (A-B) 

	 
	A

	
			
	where
	X = 
	the number of shares of Warrant Stock to be issued to Holder pursuant to a net exercise of this Warrant effected pursuant to this Section 2.6.

	 
	 
	 

	 
	Y =
	the Purchase Amount divided by the Warrant Price.

	 
	 
	 

	 
	A =
	the fair market value of one share of Warrant Stock, determined at the time of such net exercise as set forth in the last paragraph of this Section 2.6.

	 
	 
	 

	 
	B =
	the Warrant Price.

The Company will promptly respond in writing to an inquiry by Holder as to the then current fair market value of one share of Warrant Stock.
2.6.2    For purposes of the above calculation, fair market value of one share of Warrant Stock shall be determined by the Company’s Board of Directors in good faith; provided, however, that if on the relevant exercise date for which such value must be determined, then the fair market value per share of the Warrant Stock shall be the per-share offering price to the public as set forth in the Company’s final prospectus filed with the Securities and Exchange Commission.
3.    ISSUANCE OF STOCK. Except as set forth in Section 4, this Warrant shall be deemed to have been exercised immediately prior to the close of business on the date of its surrender for exercise as provided above, and the person entitled to receive the shares of Warrant Stock issuable upon such exercise shall be treated for all purposes as the holder of record of such shares as of the close of business on such date. As soon as practicable on or after such date, the Company shall issue and deliver to the person or persons entitled to receive the same a certificate or certificates for the number of whole shares of Warrant Stock issuable upon such exercise, together with payment of any fractional shares pursuant to Section 2.4.
4.    EXERCISES IN CONNECTION WITH CERTAIN TRANSACTIONS. If the Company proposes at any time to effect a Deemed Liquidation Event or an Initial Public Offering, the Company shall give the Holder at least ten (10) days advance written notice (each, a “Transaction Notice”) of the anticipated closing date for such Deemed Liquidation Event or the anticipated initial closing date for such Initial Public Offering, as applicable.
If pursuant to a Transaction Notice, Holder has not elected to exercise this Warrant under Section 2 in connection with a Deemed Liquidation Event or an Initial Public Offering, then upon the effective date of the Deemed Liquidation Event or the initial closing of the Initial Public Offering, this Warrant shall automatically be deemed net exercised in full pursuant to Section 2.6 above.

5.    ADJUSTMENT PROVISIONS. The number and character of shares of Warrant Stock issuable upon exercise of this Warrant and the Warrant Price therefor, are subject to adjustment upon each event in Sections 5.1 through 5.4 occurring between the date this Warrant is issued and earlier of the time that it is exercised in full or the Expiration Date:
5.1    Adjustment for Stock Splits and Stock Dividends, Etc.. If the Company declares or pays a dividend or distribution on the outstanding shares of the Warrant Stock payable in Common Stock or other securities or property (other than cash), then upon exercise of this Warrant, for each share of Warrant Stock acquired, Holder shall receive, without additional cost to Holder, the total number and kind of securities and property which Holder would have received had Holder owned the shares of Warrant Stock of record as of the date the dividend or distribution occurred. If the Company subdivides the outstanding shares of Warrant Stock by reclassification or otherwise into a greater number of shares, the number of shares of Warrant Stock purchasable hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased. If the outstanding shares of Warrant Stock are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased and the number of shares of Warrant Stock shall be proportionately decreased.
5.2    Adjustment for Other Dividends and Distributions. In case the Company shall make or issue, or shall fix a record date for the determination of eligible holders entitled to receive a dividend or other distribution payable with respect to the Warrant Stock that is payable in (a) securities of the Company (other than issuances with respect to which adjustment is made under Section 5.1 or Section 5.3) or (b) assets (other than cash) which dividend or distribution is actually made (each a “Dividend Event”), then, and in each such case, Holder, upon exercise of this Warrant at any time after such Dividend Event, shall receive, in addition to the shares of Warrant Stock, the securities or such other assets of the Company that would have been payable to Holder if Holder had completed such exercise of this Warrant, immediately prior to such Dividend Event.
5.3    Adjustment for Reorganization, Consolidation, Merger. (a) In case of any recapitalization or reorganization of the Company or (b) in case the Company shall consolidate with or merge into one or more other corporations or entities which results in a change of the Warrant Stock (each, a “Reorganization Event”), then, and in each such case, Holder, upon the exercise of this Warrant after 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 upon such exercise prior to such Reorganization Event, the stock or other securities or property which Holder would have been entitled to receive upon such Reorganization Event if, immediately prior to such Reorganization Event, Holder had completed such exercise of this Warrant, all subject to further adjustment as provided in this Warrant. If after such Reorganization Event, the Warrant is exercisable for securities of a corporation or entity other than the Company, then such corporation or entity shall duly execute and deliver to Holder a supplement hereto acknowledging such corporation’s or other entity’s obligations under this Warrant; and in each such case, the terms of this Warrant shall be applicable to the shares of stock or other securities or property receivable upon the exercise of this Warrant after the consummation of such Reorganization Event.
5.4    Conversion of Stock. In case all (a) the authorized Warrant Stock is converted, pursuant to the Company’s Certificate of Incorporation, into Common Stock or other securities or property, or (b) the Warrant Stock otherwise ceases to exist or to be authorized by the Company’s Certificate of Incorporation (each, a “Stock Event”), then Holder, upon exercise of this Warrant at any time after such Stock Event, shall receive, in lieu of the number of shares of Warrant Stock that would have been issuable upon exercise of this Warrant immediately prior to such Stock Event, the stock and other securities and 

5

property that Holder would have been entitled to receive upon the Stock Event, if, immediately prior to such Stock Event, Holder had completed such exercise of this Warrant.
5.5    Notice of Adjustments. Upon the occurrence of each adjustment or readjustment or the Warrant Price or the number of shares of Warrant Stock or other securities issuable upon the exercise of this Warrant, the Company, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and shall promptly give written notice to the Holder of each adjustment under Section 5 of the Warrant Price or the number of shares of Warrant Stock or other securities that remain issuable upon exercise of this Warrant. The notice shall describe the adjustment and show in reasonable detail the facts on which the adjustment or readjustment is based.
5.6    No Change Necessary. The form of this Warrant need not be changed because of any adjustment in the Warrant Price or in the number of shares of Warrant Stock issuable upon its exercise.
5.7    Reservation of Stock. If the number of shares of Warrant Stock or other securities issuable upon exercise of this Warrant that are authorized and unissued under the Company’s Certificate of Incorporation shall not be sufficient to effect the exercise of this Warrant in full, the Company will promptly take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Warrant Stock or other securities issuable upon exercise of this Warrant as shall be sufficient for such purpose.
6.    NO IMPAIRMENT. The Company will not, by amendment of its Certificate of Incorporation or bylaws, or through reorganization, consolidation, merger, dissolution, issue or sale of securities, sale of assets or any other voluntary action, willfully avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the holder against wrongful impairment. Without limiting the generality of the foregoing, the Company will take all such action as may be necessary or appropriate in order that the Company may duly and validly issue fully paid and nonassessable shares of Warrant Stock upon the exercise of this Warrant.
7.    PROVISIONS RELATING TO STOCKHOLDER RIGHTS.
7.1    No Voting or Other Rights. This Warrant 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 Warrant is actually validly exercised for shares of the Company’s capital stock in accordance with its terms. In the absence of valid exercise of this Warrant, no provisions of this Warrant, and no enumeration herein of the rights or privileges of Holder, shall cause Holder to be a stockholder of the Company for any purpose.

Permitted transfers with respect to Section 9 include (i) a transfer not involving a change in beneficial ownership, except that in the case of a transfer of 100% of the shares of SRM held by the Holder at the time of such share transfer, the transfer of this Warrant to the

THIS CERTIFICATE MUST BE SURRENDERED TO THE COMPANY OR ITS TRANSFER AGENT AS A CONDITION PRECEDENT TO THE SALE, TRANSFER, PLEDGE OR HYPOTHECATION OF ANY INTEREST IN ANY OF THE SECURITIES REPRESENTED HEREBY.
