(F) The term “Warrant Shares” shall mean the Common Stock issuable upon exercise of this Warrant.

1. Exercise of Warrant.

1.1. Number of Shares Issuable upon Exercise. From and after the Issue Date through and including the Expiration Date, the Holder shall be entitled to receive, upon exercise of this Warrant in whole in accordance with the terms of Section 1.2, shares of Common Stock of the Company, subject to adjustment pursuant to Section 4 below.

1.2. Full Exercise. This Warrant may be exercised only in full by the Holder hereof by delivery to the Company of an original or facsimile copy of the form of subscription attached as Exhibit A hereto (the “Subscription Form”) duly executed by such Holder, to the Company at its principal office, accompanied by payment, in cash, wire transfer or by certified or official bank check payable to the order of the Company, in the amount obtained by multiplying the number of shares of Common Stock for which this Warrant is then exercisable by the Purchase Price then in effect. The Holder shall surrender this Warrant within two days after receipt of the Common Stock to the Company at its principal office.

1.3. Delivery of Stock Certificates, etc. on Exercise. The Company agrees that, provided the full purchase price listed in the Subscription Form is received as specified in Section 1.2, the shares of Common Stock purchased upon exercise of this Warrant shall be deemed to be issued to the Holder hereof as the record owner of such shares as of the close of business on the date on which delivery of a Subscription Form shall have occurred and payment made for such shares as aforesaid. As soon as practicable after the exercise of this Warrant in full, and in any event within five (5) business days thereafter (“Warrant Share Delivery Date”), the Company at its expense (including the payment by it of any applicable issue taxes) will cause to be issued in the name of and delivered to the Holder hereof, or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct in compliance with applicable securities laws, a certificate or certificates for the number of duly and validly issued, fully paid and non-assessable shares of Common Stock (or Other Securities) to which such Holder shall be entitled on such exercise, plus, in lieu of any fractional share to which such Holder would otherwise be entitled, cash equal to such fraction multiplied by the then Fair Market Value of one full share of Common Stock, together with any other stock or Other Securities and property (including cash, where applicable) to which such Holder is entitled upon such exercise pursuant to Section 1 or otherwise.

2. Cashless Exercise.

(a) Except as otherwise provided in this Section 2(a), this Warrant may be exercisable in whole for cash only as set forth in Section 1, above. If, however, (a) the Company has defaulted in the performance of any of its material liabilities, obligations and commitments pursuant to Section 11.1 of the Subscription Agreement, but only for so long as such default remains uncured, or (b) the Company is subject to a Corporate Transaction, and only with respect to Warrant Shares not included

3

for unrestricted public resale in an effective Registration Statement on the date notice of exercise is given by the Holder, payment upon exercise may be made at the option of the Holder either in (i) cash, wire transfer or by certified or official bank check payable to the order of the Company equal to the applicable aggregate Purchase Price, (ii) by delivery of Common Stock issuable upon exercise of this Warrant in accordance with Section 2(b) below (a “Cashless Exercise”) or (iii) by a combination of any of the foregoing methods, for the number of shares of Common Stock specified in such form (as such exercise number shall be adjusted to reflect any adjustment in the total number of shares of Common Stock issuable to the Holder per the terms of this Warrant) and the Holder shall thereupon be entitled to receive the number of duly authorized, validly issued, fully-paid and non-assessable shares of Common Stock (or Other Securities) determined as provided herein.

(b) Subject to the provisions herein to the contrary, if the Fair Market Value of one share of Common Stock is greater than the Purchase Price (at the date of calculation as set forth below), and to the extent that a Cashless Exercise is permitted under Section 2(a) above, in lieu of exercising this Warrant for cash, the holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being cancelled) together with the delivery of a properly endorsed Subscription Form delivered to the Company by any means described in Section 11, in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:

For purposes of Rule 144 promulgated under the 1933 Act, it is intended, understood and acknowledged that, pursuant to applicable law, the Warrant Shares issued in a cashless exercise transaction in the manner described above shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the Issue Date. Notwithstanding the foregoing, the Company can provide no assurances to Holder that the law at the time of exercise will be the same as existing law, and the Holder assumes all risk in connection therewith.

3. Corporate Transactions. In the event of a Corporate Transaction, any surviving corporation or acquiring corporation may, but shall not be obligated to, assume or continue this Warrant or substitute a similar warrant for this Warrant (it being understood that similar warrants include, but are not limited to, warrants to acquire the same consideration paid to the stockholders or the Company, as the case may be, pursuant to the Corporate Transaction), and any reacquisition or repurchase rights held by the Company in respect of Common Stock issued pursuant to this Warrant may be assigned by the Company to the successor of the Company (or such successor’s parent company), if any, in connection with such Corporate Transaction. In the event that any surviving corporation or acquiring corporation does not assume or continue this Warrant or substitute a similar warrant for this Warrant, then (a) if the Fair Market Value of one share of Common Stock is greater than the Purchase Price (at the date of calculation as set forth in Section 2(b) above), this Warrant shall be deemed to have been automatically

4

exercised by the Holder by a Cashless Exercise immediately prior to the Closing, or (b) if the Fair Market Value of one share of Common Stock is not greater than the Purchase Price, the Company may cancel this Warrant effective as of the consummation of such Corporate Transaction (the “Closing”), provided that it will notify the Holder of the proposed Corporate Transaction a reasonable period of time prior to the Closing so that the Holder will be given an opportunity to exercise this Warrant prior to the cancellation thereof.

4. Extraordinary Events Regarding Common Stock. In the event that the Company shall (a) issue additional shares of Common Stock as a dividend or other distribution on outstanding Common Stock, (b) subdivide its outstanding shares of Common Stock, or (c) combine its outstanding shares of the Common Stock into a smaller number of shares of Common Stock, then, in each such event, the Purchase Price shall, simultaneously with the happening of such event, be adjusted by multiplying the then Purchase Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the Purchase Price then in effect. The Purchase Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described herein in this Section 4. The number of shares of Common Stock that the Holder of this Warrant shall thereafter, on the exercise hereof, be entitled to receive shall be adjusted to a number determined by multiplying the number of shares of Common Stock that would otherwise (but for the provisions of this Section 4) be issuable on such exercise by a fraction of which (a) the numerator is the Purchase Price that would otherwise (but for the provisions of this Section 4) be in effect, and (b) the denominator is the Purchase Price in effect on the date of such exercise.

5. Certificate as to Adjustments. In each case of any adjustment or readjustment in the shares of Common Stock (or Other Securities) issuable on the exercise of this Warrant, the Company at its expense will promptly cause its Chief Financial Officer or other appropriate designee to compute such adjustment or readjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based, including a statement of (a) the consideration received or receivable by the Company for any additional shares of Common Stock (or Other Securities) issued or sold or deemed to have been issued or sold, (b) the number of shares of Common Stock (or Other Securities) outstanding or deemed to be outstanding, and (c) the Purchase Price and the number of shares of Common Stock to be received upon exercise of this Warrant, in effect immediately prior to such adjustment or readjustment and as adjusted or readjusted as provided in this Warrant. The Company will forthwith mail a copy of each such certificate to the Holder and any Warrant Agent of the Company (appointed pursuant to Section 9 hereof).

6. Reservation of Stock, etc. Issuable on Exercise of Warrant; Financial Statements. The Company will at all times reserve and keep available, solely for issuance and delivery on the exercise of this Warrant, all shares of Common Stock (or Other Securities) from time to time issuable on the exercise of this Warrant.

7. Assignment; Exchange of Warrant. Subject to compliance with applicable securities laws, and subject to the restrictive covenants set forth in Section 4(p) of the Subscription Agreement, this Warrant, and the rights evidenced hereby, may be transferred by any registered holder hereof (a “Transferor”). On the surrender for exchange of this Warrant, with the Transferor’s endorsement in the form of Exhibit B attached hereto (the “Transferor Endorsement Form”) and together with an opinion of counsel reasonably satisfactory to the Company that the transfer of this Warrant will be in compliance with applicable securities laws, the Company, at the Holder’s expense, but with payment by the Transferor of any applicable transfer taxes, will issue and deliver to or on the order of the Transferor

5

thereof a new Warrant or Warrants of like tenor, in the name of the Transferor and/or the transferee(s) specified in such Transferor Endorsement Form (each a “Transferee”), calling in the aggregate on the face or faces thereof for the number of shares of Common Stock called for on the face or faces of this Warrant so surrendered by the Transferor. No such transfers shall result in a public distribution of this Warrant.

8. Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement or security reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, on surrender and cancellation of this Warrant, the Company at the Holder’s expense, will execute and deliver, in lieu thereof, a new Warrant of like tenor.

9. Warrant Agent. The Company may, by written notice to the Holder of this Warrant, appoint an agent (a “Warrant Agent”) for the purpose of issuing Common Stock (or Other Securities) on the exercise of this Warrant pursuant to Section 1, exchanging this Warrant pursuant to Section 7, and replacing this Warrant pursuant to Section 8, or any of the foregoing, and thereafter any such issuance, exchange or replacement, as the case may be, shall be made at such office by such Warrant Agent.

10. Transfer on the Company’s Books. Until this Warrant is transferred on the books of the Company, the Company may treat the registered holder hereof as the absolute owner hereof for all purposes, notwithstanding any notice to the contrary.
