	2.		Exercise of Warrants.

     (a) Payment. A Warrant may be exercised by the registered holder thereof by surrendering it, at the office of the Company, for the number of shares of Common Stock which the registered holder is entitled to receive as an Earnout Award pursuant to Section 2.06 of the Merger Agreement, as well as any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for shares of Common Stock, and the issuance of the Common Stock. The registered holder shall not be required to provide any additional

consideration upon the exercise of the Warrant or the issuance of Common Stock upon exercise of a Warrant.

     (b) As soon as practicable after the exercise of any Warrant, the Company shall issue to the registered holder of such Warrant a certificate or certificates for the number of full shares of Common Stock to which he is entitled pursuant to the exercise of the Warrant, registered in such name or names as may be directed by him, her or it, and additionally if such Warrant shall not have been exercised in full, a new countersigned Warrant for the number of shares as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver any securities pursuant to the exercise of a Warrant unless a registration statement under the Act and all applicable state securities laws with respect to the Common Stock is effective or an exemption under the Act and all applicable state securities laws is available for the issuance.

     (c) All shares of Common Stock issued upon the proper exercise of a Warrant in conformity with this Warrant shall be validly issued, fully paid and nonassessable.

     (d) Each person in whose name any such certificate for shares of Common Stock is issued shall for all purposes be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered, irrespective of the date of delivery of such certificate, 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 re-opened, which shall be the earliest practical date available to the Company.

	3.		No Fractional Shares. Notwithstanding any other provision of this Warrant or the Merger Agreement, no fractional shares of Common Stock shall be issued pursuant to the terms of this Warrant, and no Member shall be entitled to receive a fractional share of Common Stock pursuant to the terms of this Warrant.
	4.		Transfer and Exchange of Warrants.

     (a) Registration of Transfer. The Company shall register the transfer, from time to time, of any outstanding Warrant in the Warrant register, upon the surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Company.

     (b) Procedure for Surrender of Warrants. Warrants may be surrendered to the Company, together with a written request for exchange or transfer, and thereupon the Company shall issue in exchange therefor one or more new Warrants as requested by the registered holder of the Warrants so surrendered, representing an equal aggregate number of Warrants.

     (c) Partial Exercise. If the Warrant shall have been exercised in part, the Company shall, at the time of delivery of the certificate or certificates representing shares of Parent Common Stock, deliver to holder a new Warrant evidencing the unexercised rights of holder to acquire shares of Parent Common Stock called for by the Warrant, which new Warrant shall in all other respects be identical with the original Warrant.

2

     (d) Service Charges. No service charge shall be made for any exchange of Warrants.

5. Other Provisions Relating to Rights of Holders of Warrants.

     (a) No Rights as Stockholder. A Warrant does not entitle the registered holder thereof to any of the rights of a stockholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of the Company or any other matter. The holder shall be entitled to all rights of a stockholder of the Company with respect to shares of Common Stock issuable upon exercise of this Warrant immediately upon such exercise notwithstanding that a certificate representing such shares Common Stock has not been issued.

     (b) Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost, stolen, mutilated, or destroyed, the Company may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.

     (c) Reservation of Common Stock. The Company shall at all times that any Warrant is outstanding reserve and keep available a number of its authorized but unissued             shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants.

     (d) Registration of Common Stock. The registration of the Common Stock issuable pursuant to the terms of this Warrant shall be subject to that certain Registration Rights Agreement, dated [                     ___], 2007 by and between the Company, the Members’ Representative and the members of Multi-Shot, LLC.
