              Within

      representing all accrued and unpaid interest under the Debenture as of
      February 23, 2010.

            


    

    


    
      	
               
      

            	
              (f)

            	
              Section
      5.1 of the Debentures is hereby deleted and replaced with the
      following:

            


    

     

    
      	
               
      

            	
              5.1

            	
              The
      Holder may, at its election, upon surrender (either in person, by mail
      (postage `prepaid) or other means of delivery) of this Debenture along
      with a completed a notice of conversion (the "Conversion Notice") in
      the form attached hereto as Schedule "A" at the principal
      office of the Corporation in the city of Greenwood Village, Colorado at
      any time prior to the close of business on August 23, 2010, convert the
      Principal Sum, in whole or in part, into fully paid and non-assessable
      Common Shares, as presently constituted (without adjustment for dividends
      on Common Shares issuable upon conversion).  The Debenture may
      be converted on or prior to the Maturity Date, or in the event that the
      Principal Sum is not repaid on the Maturity Date, at any time until such
      date that the Principal Sum is repaid, at a conversion price of US$0.50
      per Common Share (as adjusted for share splits, share consolidations and
      other similar events) (the "Conversion Price"),
      being a rate of 2,000 Common Shares per US$1,000 principal amount of
      Debentures.  If the Holder elects to convert the Principal Sum,
      or any portion thereof, the Holder may also, at its election, concurrently
      convert any accrued but unpaid interest at that time outstanding in
      respect of such Principal Sum into Common Shares at the Conversion
      Price.  The endorsement of the Conversion Notice by the Holder
      and the surrender of the Debenture shall be deemed to constitute a
      contract between the Holder and the Corporation whereby (i) the Holder
      subscribes for the number of Common Shares which he shall be entitled to
      receive upon such conversion, (ii) the Holder releases the Corporation
      from all liability thereon or from all liability with respect to the
      portion of the principal amount and corresponding accrued interest, if
      applicable, thereof to be converted, as the case may be, and (iii) the
      Corporation agrees that the surrender of the Debenture for conversion
      constitutes full payment of the subscription price for the Common Shares
      issuable on such conversion and to the extent
  thereof.

            


    

    As
promptly as possible after receipt of the Conversion Notice and the Debenture
but subject to Section 5.3 hereto, the Corporation shall issue or cause to be
issued and deliver or cause to be delivered to the Holder a certificate or
certificates in the name or names of the person or persons specified in the
Conversion Notice for the number of Common Shares deliverable upon the
conversion of the Debenture. Upon completion of the conversion transaction, the
rights of the Holder to receive, in respect of the amount hereof so converted,
the Principal Sum and interest thereon, shall cease and the Holder or the other
person or persons in whose name or names any certificate or certificates for
Common Shares shall be deliverable upon such conversion shall be deemed to have
become on such date the holder or holders of record of such Common Shares
represented thereby.

    Any part,
being $1,000 or an integral multiple thereof, of a Debenture of a denomination
in excess of $1,000 may be converted as provided herein and all references
herein to the  conversion of the Debenture shall be deemed to include
conversion of such parts.  If the Holder converts only part of the
Principal Sum, upon the exercise of his right of conversion, the Holder shall
surrender such Debenture to the Corporation, and the Corporation shall cancel
the same and shall, without charge, forthwith certify and deliver to the Holder
a new Debenture or Debentures in an aggregate principal amount equal to the
unconverted part of the Principal Sum of the Debenture so
surrendered.

    


    
      	
               
      

            	
              (g)

            	
              Section
      5.2 of the Debentures is hereby deleted and replaced with the
      following:

            


    

     

    
      	
               
      

            	
              5.2

            	
              Subject
      to the restrictions set forth in Section 5.3 hereto, the Corporation shall
      have the right to force the Holder to convert the Principal Sum into
      Common Shares (a "Forced
      Conversion") under the terms described in Section 5.1
      if:

            


    

    


    
      	
               
      

            	
              (a)

            	
              at
      any time after September 24, 2007, but prior to the Maturity Date, in the
      event that the 20 day weighted average trading price of the Common Shares
      on the AMEX (or if the Common Shares are not listed on the AMEX, the TSX,
      or if the Common Shares are not listed on the TSX, any other exchange on
      which the Common Shares are then listed) equals or exceeds US$0.90 per
      share (as adjusted for share splits, share consolidations and other
      similar events); or

            


    

    


    
      	
            	
              (b) 

            	
              there
      is a Change of Control of the
Corporation.

            


    

    


    In order
to initiate a Forced Conversion, the Corporation must provide the Holder with
written notice (the "Forced
Conversion Notice") 60 days prior to the effective date (the "Forced Conversion Date") of
the Forced Conversion.

    


    In the
event of a Forced Conversion, the Corporation will be required to pay any
interest that would have accrued from the Forced Conversion Date to the Maturity
Date, notwithstanding any early repayment of such interest.

    


    Notwithstanding
the foregoing, the Corporation may not implement a Forced Conversion unless the
Common Shares issuable upon conversion may be freely resold by the Holder, as a
selling shareholder and not as an underwriter, under an effective registration
statement filed with the Securities and Exchange Commission and legal counsel to
the Corporation has delivered an opinion letter to the Holder and the
Corporation's transfer agent that the Common Shares issuable upon conversion may
be sold in the United States under the registration statement or pursuant to an
exemption without volume limitations or restriction.

              Except
      as expressly amended hereby, the Debentures are in all respects ratified
      and confirmed and all the terms, conditions and provisions thereof shall
      remain in full force and effect.
