(i) surrender of this Warrant to the Company at its then principal executive offices (or an indemnification undertaking with respect to this Warrant in the case of its loss, theft or destruction), together with a Notice of Exercise in the form attached hereto as Exhibit A (each, a “Notice of Exercise”), duly completed (including specifying the number of Warrant Shares to be purchased) and executed; and

(ii) payment to the Company of the Aggregate Exercise Price in accordance with Section 4(b) hereof.

(b) Payment of the Aggregate Exercise Price. Payment of the Aggregate Exercise Price shall be made, at the option of the Holder as expressed in the Notice of Exercise, by the following methods:

(i) by delivery to the Company of a certified or official bank check payable to the order of the Company or by wire transfer of immediately available funds to an account designated in writing by the Company, in the amount of such Aggregate Exercise Price;

(ii) by instructing the Company to withhold a number of Warrant Shares then issuable upon exercise of this Warrant with an aggregate Fair Market Value as of the Exercise Date equal to such Aggregate Exercise Price;

(iii) by surrendering to the Company Common Stock, including Warrant Shares previously acquired by the Holder, with an aggregate Fair Market Value as of the Exercise Date equal to such Aggregate Exercise Price; provided, that such payment will not conflict with, or result in a breach or violation of, any of the terms or provisions of, or constitute a default under (in each case, with or without notice or lapse of time, or both), or result, in the acceleration of, or the creation of any lien under, any indenture, mortgage, deed of trust, loan agreement or other agreement, instrument, contract or other arrangement to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject; or

(iv) any combination of the foregoing.

In the event of any withholding of Warrant Shares or Common Stock pursuant to clause (ii), (iii) or (iv) above where the number of shares whose value is equal to the Aggregate Exercise Price is not a whole number, the number of shares withheld by or surrendered to the Company shall be rounded up to the nearest whole share (the fractional amount that is needed to round up to the whole share, “Incremental Fraction”), and the Company shall make a cash payment to the Holder (by delivery of a certified or official bank check or by wire transfer of immediately available funds) in an amount equal to the product of (x) such Incremental Fraction multiplied by (y) the Fair Market Value per share of Common Stock as of the Exercise Date.

- 6 -

(c) Delivery of Stock Certificates. Upon receipt by the Company of the Notice of Exercise, surrender of this Warrant and payment of the Aggregate Exercise Price (in accordance with Section 4(a) hereof), the Company shall, as promptly as practicable, and in any event within five (5) Business Days thereafter, execute (or cause to be executed) and deliver (or cause to be delivered) to the Holder a certificate or certificates representing the Warrant Shares issuable upon such exercise, together with cash in lieu of any fraction of a share, as provided in Section 4(d) hereof. The stock certificate or certificates so delivered shall be, to the extent possible, in such denomination or denominations as the exercising Holder shall reasonably request in the Notice of Exercise and shall be registered in the name of the Holder or, subject to compliance with Section 6 hereof, such Person’s name as shall be designated in the Notice of Exercise. This Warrant shall be deemed to have been exercised and such certificate or certificates of Warrant Shares shall be deemed to have been issued, and the Holder or any other Person so designated to be named therein shall be deemed to have become a holder of record of such Warrant Shares for all purposes, as of the Exercise Date.

(d) Fractional Shares. The Company shall not be required to issue a fractional Warrant Share upon exercise of any Warrant. As to any fraction of a Warrant Share that the Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay to such Holder an amount in cash (by delivery of a certified or official bank check or by wire transfer of immediately available funds) equal to the product of (i) such fraction multiplied by (ii) the Fair Market Value of one Warrant Share on the Exercise Date.

(e) Delivery of New Warrant. Unless the purchase rights represented by this Warrant shall have expired or shall have been fully exercised, the Company shall, at the time of delivery of the certificate or certificates representing the Warrant Shares being issued in accordance with Section 4(c) hereof, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unexpired and unexercised Warrant Shares called for by this Warrant. Such new Warrant shall in all other respects be identical to this Warrant.

(f) Valid Issuance of Warrant and Warrant Shares; Payment of Taxes. With respect to the exercise of this Warrant, the Company hereby represents, covenants and agrees:

(i) this Warrant is, and any Warrant issued in substitution for or replacement of this Warrant shall be, upon issuance, duly authorized and validly issued;

(ii) all Warrant Shares issuable upon the exercise of this Warrant pursuant to the terms hereof shall be, upon issuance, and the Company shall take all such actions as may be necessary or appropriate in order that such Warrant Shares are, validly issued, fully paid and non-assessable, issued without violation of any preemptive or similar rights of any shareholder of the Company;

- 7 -

(iii) the Company shall take all such actions as may be necessary to ensure that all such Warrant Shares are issued without violation by the Company of any applicable law or governmental regulation or any requirements of any domestic securities exchange upon which shares of Common Stock or other securities constituting Warrant Shares may be listed at the time of such exercise (except for official notice of issuance which shall be immediately delivered by the Company upon each such issuance); and

(iv) the Company shall use its commercially reasonable efforts to cause the Warrant Shares, immediately upon such exercise, to be listed on any domestic securities exchange upon which shares of Common Stock or other securities constituting Warrant Shares are listed at the time of such exercise.

(g) Conditional Exercise. Notwithstanding any other provision hereof, if an exercise of any portion of this Warrant is to be made in connection with a public offering or a sale of the Company (pursuant to a merger, sale of stock, or otherwise), such exercise may, at the election of the Holder, be conditioned upon the consummation of such transaction, in which case such exercise shall not be deemed to be effective until immediately prior to the consummation of such transaction.

(h) Reservation of Shares. During the Exercise Period, the Company shall at all times reserve and keep available out of its authorized but unissued Common Stock, solely for the purpose of issuance upon the exercise of this Warrant, the maximum number of Warrant Shares issuable upon the exercise of this Warrant, and the par value per Warrant Share shall at all times be less than or equal to the applicable Exercise Price. The Company shall not increase the par value of any Warrant Shares receivable upon the exercise of this Warrant above the Exercise Price then in effect, and shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant.

5. Adjustment Exercise Price and to Number of Warrant Shares. The number of Warrant Shares issuable upon exercise of this Warrant shall be subject to adjustment from time to time as provided in this Section 5 (in each case, after taking into consideration any prior adjustments pursuant to this Section 5).

(a) Dividends, Subdivision and Combination of Common Stock. If the Company shall, at any time or from time to time after the Original Issue Date, (i) pay a dividend or make any other distribution upon the Common Stock payable in shares of Common Stock, Options, Convertible Securities or cash or other property or (ii) subdivide (by any stock split, recapitalization or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to any such dividend, distribution or subdivision shall be proportionately reduced and the number of Warrant Shares issuable upon exercise of this Warrant shall be proportionately increased. If the Company at any time combines (by combination, reverse stock split or otherwise) its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be proportionately increased and the number of Warrant Shares issuable upon exercise of this Warrant shall be proportionately decreased. Any adjustment under this Section 5(a) shall become effective at the close of business on the date the dividend, subdivision or combination becomes effective.

- 8 -

(b) Reorganization, Reclassification, Merger, Consolidation or Disposition of Assets. In the event of any (i) capital reorganization of the Company, (ii) reclassification of the stock of the Company (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 stock dividend or subdivision, split-up or combination of shares), (iii) consolidation or merger of the Company with or into another Person, (iv) sale of all or substantially all of the Company’s assets to another Person or (v) other similar transaction (other than any such transaction covered by Section 5(a) hereof), in each case which entitles the holders of Common Stock to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock, each Warrant shall, immediately after such reorganization, reclassification, consolidation, merger, sale or similar transaction, remain outstanding and shall thereafter, in lieu of or in addition to (as the case may be) the number of Warrant Shares then exercisable under this Warrant, be exercisable for the kind and number of shares of stock or other securities or assets of the Company or of the successor Person resulting from such transaction to which the Holder would have been entitled upon such reorganization, reclassification, consolidation, merger, sale or similar transaction if the Holder had exercised this Warrant in full immediately prior to the time of such reorganization, reclassification, consolidation, merger, sale or similar transaction and acquired the applicable number of Warrant Shares then issuable hereunder as a result of such exercise (without taking into account any limitations or restrictions on the exercisability of this Warrant); and, in such case, appropriate adjustment (in form and substance satisfactory to the Holder) shall be made with respect to the Holder’s rights under this Warrant to insure that the provisions of this Section 5 hereof shall thereafter be applicable, as nearly as possible, to this Warrant in relation to any shares of stock, securities or assets thereafter acquirable upon exercise of this Warrant (including, in the case of any consolidation, merger, sale or similar transaction in which the successor or purchasing Person is other than the Company, an immediate adjustment in the Exercise Price to the value per share for the Common Stock reflected by the terms of such consolidation, merger, sale or similar transaction, and a corresponding immediate adjustment to the number of Warrant Shares acquirable upon exercise of this Warrant without regard to any limitations or restrictions on exercise, if the value so reflected is less than the Exercise Price in effect immediately prior to such consolidation, merger, sale or similar transaction). The provisions of this Section 5(b) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales or similar transactions. The Company shall not effect any such reorganization, reclassification, consolidation, merger, sale or similar transaction unless, prior to the consummation thereof, the successor Person (if other than the Company) resulting from such reorganization, reclassification, consolidation, merger, sale or similar transaction, shall assume, by written instrument substantially similar in form and substance to this Warrant and satisfactory to the Holder, the obligation to deliver to the Holder such shares of stock, securities or assets which, in accordance with the foregoing provisions, such Holder shall be entitled to receive upon exercise of this Warrant. Notwithstanding anything to the contrary contained herein, with respect to any corporate event or other transaction contemplated by the provisions of this Section 5(b), the Holder shall have the right to elect prior to the consummation of such event or transaction, to give effect to the exercise rights contained in Section 2 hereof instead of giving effect to the provisions contained in this Section 5(b) with respect to this Warrant.

- 9 -

(c) Certain Events. If any event of the type contemplated by the provisions of this Section 5 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features) occurs, then the Board shall make an appropriate adjustment in the Exercise Price and the number of Warrant Shares issuable upon exercise of this Warrant so as to protect the rights of the Holder in a manner consistent with the provisions of this Section 5; provided, that no such adjustment pursuant to this Section 5(d) shall increase the Exercise Price or decrease the number of Warrant Shares issuable as otherwise determined pursuant to this Section 5.

(d) Certificate as to Adjustment.

(i) As promptly as reasonably practicable following any adjustment of the Exercise Price, but in any event not later than fifteen (15) days thereafter, the Company shall furnish the Holder with notice setting forth in reasonable detail such adjustment and the facts upon which it is based and certifying the calculation thereof.

(ii) As promptly as reasonably practicable following the receipt by the Company of a written request by the Holder, but in any event not later than ten (10) Business Days thereafter, the Company shall furnish to the Holder a certificate of an executive officer certifying the Exercise Price then in effect and the number of Warrant Shares or the amount, if any, of other shares of stock, securities or assets then issuable upon exercise of the Warrant.

(e) Notices. In the event:

(i) that the Company shall take a record of the holders of its Common Stock (or other capital stock or securities at the time issuable upon exercise of the Warrant) for the purpose of entitling or enabling them to receive any dividend or other distribution, to receive any right to subscribe for or purchase any shares of capital stock of any class or any other securities, or to receive any other security;

then, and in each such case, the Company shall send or cause to be sent to the Holder at least fifteen (15) days prior to the applicable record date or the applicable expected effective date, as the case may be, for the event, a written notice specifying, as the case may be, (A) the record date for such dividend, distribution, or other right or action, and a description of such dividend, distribution or other right or action to be taken or (B) the effective date on which such Change in Control, reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up is proposed to take place and a brief description of such event, and the date, if any is to be fixed, as of which the books of the Company shall close or a record shall be taken with respect to which the holders of record of Common Stock (or such other capital stock or securities

- 10 -

at the time issuable upon exercise of the Warrant) shall be entitled to exchange their shares of Common Stock (or such other capital stock or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, and the amount per share and character of such exchange applicable to the Warrant and the Warrant Shares.

Upon such compliance, consent, surrender and delivery, the Company shall execute and deliver a new Warrant or Warrants in the name of such Person or Persons and in the denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant, if any, not so assigned and this Warrant shall promptly be cancelled. Any attempt to assign or transfer this Warrant or any rights hereunder contrary to the provisions of this Section 6 shall be null and void.

7. Holder Not Deemed a Shareholder; Limitations on Liability. Except as otherwise specifically provided herein, prior to the issuance to the Holder of the Warrant Shares to which the Holder is then entitled to receive upon the due exercise of this Warrant, the Holder shall not be entitled to vote or receive dividends or be deemed the holder of shares of capital stock of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, as such, any of the rights of a shareholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a shareholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

8. Replacement and Division.

(a) Replacement on Loss. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and upon delivery of an indemnity reasonably satisfactory to it and, in case of mutilation, upon surrender of such Warrant for cancellation to the Company, the Company at its own expense shall execute and deliver to the Holder, in lieu hereof, a new Warrant of like tenor and exercisable for an equivalent number of Warrant Shares as the Warrant so lost, stolen, mutilated or destroyed; provided, that, in the case of mutilation, no indemnity shall be required if this Warrant in identifiable form is surrendered to the Company for cancellation.
