The following is a statement of the rights of the Holder of this Warrant and the conditions to which this Warrant is subject, to which the Holder, by the acceptance of this Warrant, agrees:

1.2 “Common Stock” means the Company’s common stock, par value $0.01 per share.

1.3 “Expiration Date” means, unless earlier terminated pursuant to Section 8 hereof, the date that is ten (10) years after the issue date set forth above.

1.4 “IPO” means a firm commitment underwritten initial public offering of the Company’s Common Stock pursuant to a registration statement declared effective by the Securities and Exchange Commission.

2. Exercise of Warrant.

2.1 Exercise. Unless earlier terminated pursuant to Section 8 hereof, the purchase rights represented by this Warrant are exercisable by the Holder, in whole or in part, by the surrender of this Warrant and the Notice of Exercise annexed hereto duly executed at the Company’s principal executive office (or such other office or agency of the Company as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the Company), and upon payment of the aggregate Exercise Price of the Shares thereby purchased (by cash or by check or bank draft payable to the order of the Company); whereupon the Holder shall be entitled to receive (or shall be deemed to have received) a certificate for the number of Shares so purchased. The Company agrees that if at the time of the surrender of this Warrant and purchase of the Shares, the Holder shall be entitled to exercise this Warrant, the Shares so purchased shall be and be deemed to be issued to the Holder as the record owner of such Shares as of the close of business on the date on which this Warrant shall have been exercised as aforesaid or on such later date requested by the Holder or on such earlier date agreed to by the Holder and the Company.

2.2 Net Exercise. Unless earlier terminated pursuant to Section 8 hereof, in lieu of exercising this Warrant by payment of cash or check or bank draft payable to the order of the Company pursuant to Section 2.1 above, the Holder may elect to receive Shares equal to the value of this Warrant (or the portion thereof being exercised), at any time after the date hereof and before the close of business on the Expiration Date, by surrender of this Warrant at the Company’s principal executive office (or such other office or agency of the Company as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the Company), together with the Notice of Conversion annexed hereto, in which event the Company will issue (or shall be deemed to have issued) to the Holder, Shares in accordance with the following formula:

2.3 Value of Shares. For the purposes of Section 2.2, the fair market value of a Share is defined as follows:

(i) if the exercise is conditioned upon the Company’s IPO, and if the Company’s registration statement relating to such IPO has been declared effective by the Securities and Exchange Commission, then the fair market value shall be the initial per share offering price specified in the final prospectus with respect to the IPO;

(ii) if the exercise is conditioned upon a Change of Control, then the fair market value shall be the value received in such Change of Control by the holders of the securities as to which purchase rights under this Warrant exist;

- 2 -

(iii) if the exercise occurs after, and not in connection with the Company’s IPO, and:

(1) if the Common Stock is traded on a securities exchange, the value shall be deemed to be the average of the closing prices on such exchange or market over the thirty (30) day period ending three (3) days prior to the date of the Notice of Conversion; or

(2) if the Common Stock is actively traded over-the-counter, the value shall be deemed to be the average of the closing bid prices over the thirty (30) day period ending three (3) days prior to the date of the Notice of Conversion;

(iv) if there is no active public market, the value shall be the fair market value thereof, as determined in good faith by the Company’s Board of Directors.

2.4 Shareholder Agreements. In connection with any exercise or conversion of this Warrant pursuant to Section 2.1 or 2.2, the Holder shall execute and deliver the Counterpart Signature Page annexed hereto, agreeing to enter into and become a party to the Shareholder Agreements described therein and agrees that the Shares (and any shares of Common Stock issued or issuable upon conversion thereof) shall become subject to the rights and obligations thereof; provided, however, that if, prior to the exercise or conversion of this Warrant, any of such Shareholder Agreements are amended other than to add a new class or classes of securities in connection with an equity financing, then the Holder will not be obligated to execute such amended Shareholder Agreement unless the Holder has approved the amendment to such Shareholder Agreement.

3. Nonassessable. The Company covenants that all Shares which may be issued upon the exercise of rights represented by this Warrant will, upon exercise of the rights represented by this Warrant, be validly issued, fully paid and nonassessable and free from all taxes, liens and charges in respect of the issue thereof. Certificates for Shares purchased hereunder shall be delivered to the Holder promptly after the date on which this Warrant shall have been exercised.

4. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. With respect to any fraction of a share called for upon the exercise of this Warrant, an amount equal to such fraction multiplied by the then current fair market value (determined in accordance with Section 2.3) of a Share shall be paid in cash to the Holder.

5. Charges, Taxes and Expenses. Issuance of certificates for Shares upon the exercise of this Warrant shall be made without charge to the Holder hereof for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder.

6. No Rights as Shareholders. This Warrant does not entitle the Holder to any voting rights or other rights as a shareholder of the Company prior to the exercise hereof.

7. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall be a Saturday, a Sunday or a legal holiday, then such action may be taken or such right may be exercised on the next succeeding day that is not a Saturday, Sunday or legal holiday.

8. Early Termination; Automatic Conversion Upon Expiration. Notwithstanding anything in this Warrant to the contrary, this Warrant shall terminate upon the earlier to occur of (i) the closing of a Change of Control or (ii) 360 days following the Company’s IPO. In the event that, upon the Expiration Date, the fair market value of one Share, as determined in accordance with Section 2.3, is greater than the Exercise Price for such Share, then this Warrant, to the extent it shall not have previously been exercised or converted, shall automatically be deemed on and as of such date to be converted into Shares pursuant to Section 2.2, and the Holder shall be entitled to receive (or shall be deemed to have received) a certificate representing such Shares issued upon such conversion to the Holder.

9. Adjustments. The Exercise Price and the number of Shares purchasable hereunder are subject to adjustment from time to time as set forth in this Section 9.

9.1 Reclassification, etc. If the Company, at any time while this Warrant, or any portion hereof, remains outstanding and unexpired by reclassification of securities or otherwise, shall change any of the securities as to which purchase rights under this Warrant exist into the same or a different number of securities or any other class or classes, this Warrant shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities that were subject to the purchase rights under this Warrant immediately prior to such reclassification or other change and the Exercise Price therefor shall be appropriately adjusted, all subject to further adjustment as provided in this Section 9.

9.2 Subdivision or Combination of Shares. In the event that the Company shall at any time subdivide the outstanding securities as to which purchase rights under this Warrant exist, or shall issue a stock dividend on the securities as to which purchase rights under this Warrant exist, the number of securities as to which purchase rights under this Warrant exist immediately prior to such subdivision or to the issuance of such stock dividend shall be proportionately increased, and the Exercise Price shall be proportionately decreased, and in the event that the Company shall at any time combine the outstanding securities as to which purchase rights under this Warrant exist, the number of securities as to which purchase rights under this Warrant exist immediately prior to such combination shall be proportionately decreased, and the Exercise Price shall be proportionately increased, effective at the close of business on the date of such subdivision, stock dividend or combination, as the case may be.

9.3 Cash Distributions. No adjustment on account of cash dividends or interest on the securities as to which purchase rights under this Warrant exist will be made to the Exercise Price under this Warrant.

10. Notice of Certain Events. The Company shall provide the Holder with notice (similar in manner and in substance to the notice provided by the Company to its shareholders and/or optionholders) of a Change of Control and/or an IPO, but in any event shall provide at least twenty (20) days notice prior to the closing of a Change of Control, which notice period may be waived or shortened by or with respect to the Holder pursuant to Section 11.2.

11. Miscellaneous.

11.1 Loss, Theft, Destruction or Mutilation of Warrant.
