This Warrant is issued pursuant to the terms of that certain Secured Note and Warrant Purchase Agreement (the “Purchase Agreement”) dated as of March 4^th, 2009, in connection with the Company’s issuance to the Holder of a Secured Convertible Promissory Note dated as of the date of this Warrant (the “Note”), for the principal amount of [                    ].

In the event the consideration provided by the Holder to the Company pursuant to the Purchase Agreement as of the date hereof is less than the Holder’s Pro Rata Amount, the number of shares of Common Stock that the Holder may purchase by exercising this Warrant is one half ( ¹⁄₂) share of Common Stock of the Company (rounded down to the nearest whole share) for each one (1) share of Equity Securities the Holder receives upon conversion of the Note.

1. DEFINITIONS. As used herein, the following terms shall have the following respective meanings:

2. EXERCISE OF WARRANT. The rights represented by this Warrant may be exercised in whole or in part at any time during the Exercise Period, by delivery of the following to the Company at its address set forth above (or at such other address as it may designate by notice in writing to the Holder):

(a) An executed Notice of Exercise in the form attached hereto;

(b) Payment of the Exercise Price in cash, by check or pursuant to Section 2.1; and

(c) This Warrant.

Upon the exercise of the rights represented by this Warrant, a certificate or certificates for the Exercise Shares so purchased, registered in the name of the Holder or persons affiliated with the Holder, if the Holder so designates, shall be issued and delivered to the Holder within a reasonable time after the rights represented by this Warrant shall have been so exercised. In the event that this Warrant is being exercised for less than all of the then-current number of Exercise Shares purchasable hereunder, the Company shall, concurrently with the issuance by the Company of the number of Exercise Shares for which this Warrant is then being exercised, issue a new Warrant exercisable for the remaining number of Exercise Shares purchasable hereunder.

The person in whose name any certificate or certificates for Exercise Shares are to be issued upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which this Warrant was surrendered and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open.

2.1. Net Exercise. If the fair market value of one share of the Common Stock of the Company is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant by payment of cash, the Holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being cancelled) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Notice of Exercise in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:

X = Y (A – B)
