        1

        
          

        

      

      
        
        

      

    

     

    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
      hereof shall be entitled to receive, upon exercise of this Warrant in whole
      in
      accordance with the terms of subsection 1.2 or upon exercise of this
      Warrant in part in accordance with subsection 1.3, Common Stock of the
      Company, subject to adjustment pursuant to Section 4.

     

    1.2.         Full
      Exercise.
      This
      Warrant may be exercised in full by the Holder hereof by delivery of an original
      or facsimile copy of the form of subscription attached as Exhibit A hereto
      (the “Subscription Form”) duly executed by such Holder and surrender of the
      original Warrant within four (4) days of exercise, to the Company at its

      hereinafter), 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. 

     

    1.3.         Partial
      Exercise.
      This
      Warrant may be exercised in part (but not for a fractional share) by surrender
      of this Warrant in the manner and at the place provided in subsection 1.2
      except that the amount payable by the Holder on such partial exercise shall
      be
      the amount obtained by multiplying (a) the number of whole shares of Common
      Stock designated by the Holder in the Subscription Form by (b) the Purchase
      Price then in effect. On any such partial exercise, the Company, at its expense,
      will forthwith issue and deliver to or upon the order of the Holder hereof
      a new
      Warrant of like tenor, in the name of the Holder hereof or as such Holder (upon
      payment by such Holder of any applicable transfer taxes) may request, the whole
      number of shares of Common Stock for which such Warrant may still be exercised
      for the balance of.

      Market Value.
      Fair
      Market Value of a share of Common Stock as of a particular date (the
“Determination Date”) shall mean: 

     

    (a)       
      If
      the
      Company’s Common Stock is traded on an exchange or is quoted on the National
      Association of Securities Dealers, Inc. Automated Quotation (“NASDAQ”), National
      Market System, the NASDAQ Capital Market or the American Stock Exchange, LLC,
      then the closing or last sale price, respectively, reported for the last
      business day immediately preceding the Determination Date;

     

    (b)       
      If
      the
      Company’s Common Stock is not traded on an exchange or on the NASDAQ National
      Market System, the NASDAQ Capital Market or the American Stock Exchange, Inc.,
      but is traded in the over-the-counter market, then the average of the closing
      bid and ask prices reported for the last business day immediately preceding
      the
      Determination Date;

     

    (c)       
      Except
      as
      provided in clause (d) below, if the Company’s Common Stock is not publicly
      traded, then as the Holder and the Company agree, or in the absence of such
      an
      agreement, by arbitration in accordance with the rules then standing of the
      American Arbitration Association, before a single arbitrator to be chosen from
      a
      panel of persons qualified by education and training to pass on the matter
      to be
      decided; or

     

    (d)       
      If

      Determination Date is the date of a liquidation, dissolution or winding up,
      or
      any event deemed to be a liquidation, dissolution or winding up pursuant to
      the
      Company’s charter, then all amounts to be payable per share to holders of the
      Common Stock pursuant to the charter in the event of such liquidation,
      dissolution or winding up, plus all other amounts to be payable per share in
      respect of the Common Stock in liquidation under the charter, assuming for
      the
      purposes of this clause (d) that all of the shares of Common Stock then
      issuable upon exercise of all of the Warrants are outstanding at the
      Determination Date.

     

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

    

     

    1.5.       
      Company
      Acknowledgment.
      The
      Company will, at the time of the exercise of the Warrant, upon the request
      of
      the Holder hereof acknowledge in writing its continuing obligation to afford
      to
      such Holder any rights to which such Holder shall continue to be entitled after
      such exercise in accordance with the provisions of this Warrant. If the Holder
      shall fail to make any such request, such failure shall not affect the
      continuing obligation of the Company to afford to such Holder any such
      rights.

     

    1.6.       
      Trustee
      for Warrant Holders.
      In the
      event that a qualified bank or trust company shall have been appointed as
      trustee for the Holder of the Warrants pursuant to Subsection 3.2, such
      bank or trust company shall have all the powers and duties of a warrant agent
      (as hereinafter described) and shall accept, in its own name for the account
      of
      the Company or such successor person as may be entitled thereto, all amounts
      otherwise payable to the Company or such successor, as the case may be, on
      exercise of this Warrant pursuant to this Section 1. 

     

     1.7.       
      Delivery
      of Stock Certificates, etc. on Exercise.
      The
      Company agrees that 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 this Warrant shall
      have been surrendered and payment made for such shares as aforesaid. As soon
      as
      practicable after the exercise of this Warrant in full or in part, and in any
      event within four (4) 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 nonassessable 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.
      The Company understands that a delay in the delivery of the Warrant Shares
      after
      the Warrant Share Delivery Date could result in economic loss to the Holder.
      As
      compensation to the Holder for such loss, the Company agrees to pay (as
      liquidated damages and not as a penalty) to the Holder for late issuance of
      Warrant Shares upon exercise of this Warrant the amount of $100 per business
      day
      after the Warrant Share Delivery Date for each $10,000 of Purchase Price of
      Warrant Shares for which this Warrant is exercised which are not timely
      delivered. The Company shall pay any payments incurred under this Section in
      immediately available funds upon demand. Furthermore, in addition to any other
      remedies which may be available to the Holder, in the event that the Company
      fails for any reason to effect delivery of the Warrant Shares by the Warrant
      Share Delivery Date, the Holder may revoke all or part of the relevant Warrant
      exercise by delivery of a notice to such effect to the Company whereupon the
      Company and the Holder shall each be restored to their respective positions
      immediately prior to the exercise of the relevant portion of this Warrant,
      except that the liquidated damages described above shall be payable through
      the
      date notice of revocation or rescission is given to the Company. 

     

    2.         
      Cashless
      Exercise.

     

    (a)         
      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 cashless
      exercise in accordance with Section (b) below 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.

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

    (b)         
      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), 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)
      by surrender of this Warrant at the principal office of the Company together
      with the properly endorsed Subscription Form 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)

             
      A

    

      
        	 	
                Where

              	
                X=

              	
                the
                  number of shares of Common Stock to be issued to the
                  holder

              
	 	 	 	 
	 	 	
                Y=

              	
                the
                  number of shares of Common Stock purchasable under the Warrant
                  or, if only
                  a portion of the Warrant is being exercised, the portion of the
                  Warrant
                  being exercised (at the date of such calculation)

              
	 	 	 	 
	 	 	
                A=

              	
                the
                  average of the three highest closing sale prices of the Common
                  Stock for
                  the five (5) Trading Days immediately prior to (but not including)
                  the
                  Exercise Date

              
	 	 	 	 
	 	 	
                B=

              	
                Purchase
                  Price (as adjusted to the date of such
                  calculation)

              


      

    

     

    For
      purposes of Rule 144 promulgated under the 1933 Act, it is intended, understood
      and acknowledged that the Warrant Shares issued in a cashless exercise
      transaction 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 date
      this Warrant was originally issued pursuant to the Subscription
      Agreement.

     

    3.         
      Adjustment
      for Reorganization, Consolidation, Merger, etc.

     

    3.1.         
      Reorganization,
      Consolidation, Merger, etc.
      In case
      at any time or from time to time, the Company shall (a) effect a
      reorganization, (b) consolidate with or merge into any other person or
      (c) transfer all or substantially all of its properties or assets to any
      other person under any plan or arrangement contemplating the dissolution of
      the
      Company, then, in each such case, as a condition to the consummation of such
      a
      transaction, proper and adequate provision shall be made by the Company whereby
      the Holder of this Warrant, on the exercise hereof as provided in
      Section 1, at any time after the consummation of such reorganization,
      consolidation or merger or the effective date of such dissolution, as the case
      may be, shall receive, in lieu of the Common Stock (or Other Securities)
      issuable on such exercise prior to such consummation or such effective date,
      the
      stock and other securities and property (including cash) to which such Holder
      would have been entitled upon such consummation or in connection with such
      dissolution, as the case may be, if such Holder had so exercised this Warrant,
      immediately prior thereto, all subject to further adjustment thereafter as
      provided in Section 4.

     

    3.2.         
      Dissolution.
      In the
      event of any dissolution of the Company following the transfer of all or
      substantially all of its properties or assets, the Company, prior to such
      dissolution, shall at its expense deliver or cause to be delivered the stock
      and
      other securities and property (including cash, where applicable) receivable
      in
      accordance with Section 3.1 by the Holder upon their exercise after the
      effective date of such dissolution pursuant to this Section 3 to a bank or
      trust company (a “Trustee”) having its principal office in New York, NY, as
      trustee for the Holder. 

     

    3.3.         
      Continuation
      of Terms.
      Upon
      any reorganization, consolidation, merger or transfer (and any dissolution
      following any transfer) referred to in this Section 3, this Warrant shall
      continue in full force and effect and the terms hereof shall be applicable
      to
      the Other Securities and property receivable on the exercise of this Warrant
      after the consummation of such reorganization, consolidation or merger or the
      effective date of dissolution following any such transfer, as the case may
      be,
      and shall be binding upon the issuer of any Other Securities, including, in
      the
      case of any such transfer, the person acquiring all or substantially all of
      the
      properties or assets of the Company, whether or not such person shall have
      expressly assumed the terms of this Warrant as provided in Section 4. In
      the event this Warrant does not continue in full force and effect after the
      consummation of the transaction described in this Section 3, then only in
      such event will the Company’s securities and property (including cash, where
      applicable) receivable by the Holder of the Warrants be delivered to the Trustee
      as contemplated by Section 3.2.

    3.4         
      Share
      Issuance.
      Until
      the Expiration Date, if the Company shall issue any Common Stock except for
      the
      Excepted Issuances (as defined in the Subscription Agreement), prior to the
      complete exercise of this Warrant for a consideration less than the Purchase
      Price that would be in effect at the time of such issue, then, and thereafter
      successively upon each such issue, the Purchase Price shall be reduced to such
      other lower purchase price. For purposes of this adjustment, the issuance of
      any
      security or debt instrument of the Company carrying the right to convert such
      security or debt instrument into Common Stock or of any warrant, right or option
      to purchase Common Stock shall result in an adjustment to the Purchase Price
      upon the issuance of the above-described security, debt instrument, warrant,
      right, or option if such issuance is at a price lower than the Purchase Price
      in
      effect upon such issuance. The reduction of the Purchase Price described in
      this
      Section 3.4 is subject to the provisions of, and in addition to the other rights
      of the Holder described in, the Subscription Agreement.

     

    4.         
      Extraordinary
      Events Regarding Common Stock.
      In the
      event that the Company shall (a) issue additional shares of the 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
      the 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
      as provided in Section 1, be entitled to receive shall be adjusted to a
      number determined by multiplying the number of shares of Common Stock that
      would

      on
      the exercise of the Warrants, 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 the 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 issued or sold or deemed to have
      been
      issued or sold, (b) the number of shares of Common Stock 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 of the Warrant and any Warrant Agent
      of
      the Company (appointed pursuant to Section 11 hereof).

    7.         
      Assignment;
      Exchange of Warrant.
      Subject
      to compliance with applicable securities laws, 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 its expense,
      twice, only, but with payment by the Transferor of any applicable transfer
      taxes, will issue and deliver to or on the order of the Transferor 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 the Warrant
      so surrendered by the Transferor. No such transfers shall result in a public
      distribution of the 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 its expense, twice only, will execute and deliver, in lieu thereof,
      a
      new Warrant of like tenor.

     

    9.         
      Registration
      Rights.
      The
      Holder of this Warrant has been granted certain registration rights by the
      Company. These registration rights are set forth in the Subscription Agreement.
      The terms of the Subscription Agreement are incorporated herein by this
      reference.

     

    10.        
      Maximum
      Exercise.
      The
      Holder shall not be entitled to exercise this Warrant on an exercise
      date, in
      connection with that number of shares of Common Stock which would be in excess
      of the sum of (i) the number of shares of Common Stock beneficially owned
      by the Holder and its affiliates on an exercise date, and (ii) the number
      of shares of Common Stock issuable upon the exercise of this Warrant with
      respect to which the determination of this limitation is being made on an
      exercise date, which would result in beneficial ownership by the Holder and
      its
      affiliates of not more than 4.99% of the outstanding shares of Common Stock
      on
      such date. For the purposes of the immediately preceding sentence, beneficial
      ownership shall be determined in accordance with Section 13(d) of the
      Securities Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder.
      Subject to the foregoing, the Holder shall be limited to aggregate exercises
      which would result in the issuance of more than 4.99%. The
      Holder may decide whether to convert a Convertible Note or exercise this Warrant
      to achieve an actual 4.99% ownership position as described above.

     

    11.        
      Warrant
      Agent.
      The
      Company may, by written notice to the Holder of the Warrant, appoint an agent
      (a
“Warrant Agent”) for the purpose of issuing Common Stock 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. 

     

    12.        
      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.
