      2.           Upon
exercise of these Warrants, the registered Holder hereof shall surrender to the
stock transfer agent of the Company this Warrant Certificate together with the
form of subscription attached hereto and a certified check or bank draft payable

      3.           In
the exercise of the Warrants no fractional shares the Common Stock of the
Company shall be issued.

      

      4.           The
Company covenants and agrees that shares of Common Stock which may be delivered
upon the exercise of this Warrant will, upon delivery, be free from all taxes,
liens and charges with respect to the purchase thereof hereunder. This Warrant
shall not be exercised by Holder in any state where such exercise would be
unlawful such as a state in which the Company’s Common Stock is not registered
or qualified as the case requires.

      
        
           

        

        
           

          
            

          

        

        
           

        

      

      5.           The
Company agrees at all times to reserve or hold available a sufficient number of
shares of its Common Stock to cover the number of shares issuable upon the
exercise of this and all other Warrants of like tenor then
outstanding.

      

      6.           This
Warrant does not entitle the Holder to any voting rights or other rights as a
shareholder of the Company, or to any other rights whatsoever except the rights
herein set forth, and no dividend shall be payable to accrue in respect to this
Warrant or the interest represented hereby, or the shares which may be acquired
hereunder, until or unless, and except to the extent that this Warrant shall be
exercised and the Common Stock which may be acquired upon exercise thereof shall
become deliverable.

      

      7.           The
Common Stock underlying the Warrants shall have piggyback registration rights
and the Holder of the Warrants evidenced by this Warrant Certificate may
exercise all or any whole number of such Warrants in the manner stated hereon
from the effective date of such registration to 5:00 PM MST March 31, 2010
unless the period is extended by the Company in its sole
discretion.  Notwithstanding the foregoing, the piggyback registration
rights and the inclusion of such shares in any registration is subject to the
willingness of the managing underwriter(s) to include such shares of common
stock in any registration. Further, in the event that the Company after the date
hereof grants registration rights to any other shareholder on terms and
conditions the holder deems to be more favorable than those granted herein, the
Company agrees ti grant the same terms to the holder.

      

      8.           The
Warrants are redeemable by the Company, at its option, at $0.01 per share of
Common Stock upon 30 days prior written notice to the Holder if there is an
effective registration statement and if the closing bid price or closing selling
price of the Common Stock for 10 consecutive trading days equals $1.00 per share
or more.

      

      9.           At
the election of the Holder, the holder may force the conversion of the Warrants
to shares of common stock upon the following events: (i) if the Company’s common
stock trades at $.50 per share for 20 consecutive trading days then 50% of the
Warrants may be converted and (ii) if the Company’s common stock trades at $.50
per share for 45 consecutive trading days then 100% of the Warrants may be
converted

      

      10.           This
Warrant is exchangeable upon the surrender hereof by the Holder to the Company
for new Warrants of like tenor and date representing in the aggregate the right
to acquire the number of shares which may be acquired hereunder, each of such
new Warrants to represent the right to acquire such number of shares as may be
designated by the registered Holder at the time of such surrender.

      

      11.           The
Company may deem and treat the Holder at any time as the absolute owner hereof
for all purposes and shall not be affected by any notice to the
contrary.
