               to exercise this Warrant at any time and from time to time during the period
               beginning on the Issue Date and ending on the Expiration Date as to all or any

| | B.       
               Exercise Notice. In order to exercise this Warrant, the Holder
               shall send by facsimile transmission, at any time prior to 5:00 p.m., Eastern
               Time, on the Business Day on which the Holder wishes to effect such exercise
               (the Exercise Date), to the Company an executed copy of the
               notice of exercise in the form attached hereto as Exhibit A
               (the Exercise Notice), the original Warrant and the Exercise
               Price. The Exercise Notice shall also state the name or names (with address) in
               which the shares of Common Stock that are issuable on such exercise shall be
               issued. If shares are to be issued in the name of a person other than the
               Holder, the Holder will pay all transfer taxes payable with respect thereto. In
               the case of a dispute as to the calculation of the Exercise Price or the number
               of Warrant Shares issuable hereunder (including, without limitation, the
               calculation of any adjustment pursuant to Paragraph 6 below), the Company shall
               promptly issue to the Holder the number of Warrant Shares that are not disputed
               and shall submit the disputed calculations to a certified public accounting firm
               of national recognition (other than the Companys independent accountants)
               within two (2) Business Days following the date on which the Exercise Notice is
               delivered to the Company. The Company shall cause such accountant to calculate
               the Exercise Price and/or the number of Warrant Shares issuable hereunder and to
               notify the Company and the Holder of the results in writing no later than three
               (3) Business Days following the day on which such accountant received the
               disputed calculations (the Dispute Procedure). Such
               accountants calculation shall be deemed conclusive absent manifest error.
               The fees of any such accountant shall be borne by the party whose calculations
               were most at variance with those of such accountant.

| | C.       
               Holder of Record. The Holder shall, for all purposes, be deemed to
               have become the holder of record of the Warrant Shares specified in an Exercise
               Notice on the Exercise Date specified therein, irrespective of the date of
               delivery of such Warrant Shares. Except as specifically provided herein, nothing
               in this Warrant shall be construed as conferring upon the Holder hereof any
               rights as a stockholder of the Company prior to the Exercise Date.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | D.       
               Cancellation of Warrant. This Warrant shall be canceled upon its
               exercise and, if this Warrant is exercised in part, the Company shall, at the
               time that it delivers Warrant Shares to the Holder pursuant to such exercise as
               provided herein, issue a new warrant, and deliver to the Holder a certificate
               representing such new warrant, with terms identical in all respects to this
               Warrant (except that such new warrant shall be exercisable into the number of
               shares of Common Stock with respect to which this Warrant shall remain
               unexercised and if it has been exercised into at least 1,750,000 shares, the
               Exercise Price of the new Warrant shall be $1.00); provided,
               however, that the Holder shall be entitled to exercise all or any portion of
               such new warrant at any time following the time at which this Warrant is
               exercised, regardless of whether the Company has actually issued such new
               warrant or delivered to the Holder a certificate therefore.

2.       
          Delivery of Warrant Shares Upon Exercise. Upon receipt of an
          Exercise Notice pursuant to Paragraph 1 above, the Company shall: (i) no later
          than the close of business on the later to occur of: (a) the third (3rd)
          Business Day following the Exercise Date set forth in such Exercise Notice; and
          (b) such later date on which the Company shall have received payment of the
          Exercise Price and the taxes specified in Paragraph 1B above, if any, are paid
          in full; and (ii) with respect to Warrant Shares that are the subject of a
          Dispute Procedure, the close of business on the third (3rd) Business Day
          following the determination made pursuant to Paragraph 1B (each of the dates
          specified in (i) or (ii) being referred to as a Delivery
          Date), issue and deliver or cause to be delivered to the Holder the
          number of Warrant Shares as shall be determined as provided herein. The Company
          shall effect delivery of Warrant Shares to the Holder by, as long as the
          Transfer Agent participates in the Depository Trust Company
          (DTC) Fast Automated Securities Transfer program
          (FAST), crediting the account of the Holder or its nominee at
          DTC (as specified in the applicable Exercise Notice) with the number of Warrant
          Shares required to be delivered, no later than the close of business on such
          Delivery Date. In the event that the Transfer Agent is not a participant in
          FAST, or if the Warrant Shares are not otherwise eligible for delivery through
          FAST, or if the Holder so specifies in an Exercise Notice or otherwise in
          writing on or before the Exercise Date, the Company shall effect delivery of
          Warrant Shares by delivering to the Holder or its nominee physical certificates
          representing such Warrant Shares, no later than the close of business on such
          Delivery Date.

3.       
          Exercise Limitations. In no event shall the Holder be permitted to
          exercise this Warrant, or part thereof, if, upon such exercise, the number of
          shares of Common Stock beneficially owned by the Holder (other than shares which
          would otherwise be deemed beneficially owned except for being subject to a
          limitation on conversion or exercise analogous to the limitation contained in
          this Paragraph 3), would exceed 4.99% of the number of shares of Common Stock
          then issued and outstanding. As used herein, beneficial ownership shall be
          determined in accordance with Paragraph 13D of the Securities Exchange Act of
          1934, as amended, and the rules hereunder. To the extent that the limitation
          contained in this Paragraph 3 applies, the submission of an Exercise Notice
          by the Holder shall be deemed to be the Holders representation that this
          Warrant is exercisable pursuant to the terms hereof and the Company shall be
          entitled to rely on such representation without making any further inquiry as to
          whether this Paragraph 3 applies. The Company shall have no liability to any
          person if the Holders determination of whether this Warrant is convertible
          pursuant to the terms hereof is incorrect. Nothing contained herein shall be
          deemed to restrict the right of a Holder to exercise this Warrant, or part
          thereof, at such time as such exercise will not violate the provisions of this
          Paragraph 3. This Paragraph 3 may not be amended unless such amendment
          is approved by the holders of a majority of the Common Stock then outstanding;
          provided, however, that the Holder shall have the right, upon thirty (30)
          days prior written notice to the Company, to waive the provisions of this
          Paragraph 3 in the event that a Major Transaction (as defined below) is
          announced or occurs.

4.       
          Limitation of Selling Warrant Shares. Holder will not sell greater
          than one million seven hundred fifty thousand (1,750,000) Warrant Shares for a
          period of three (3) years from the Issue Date.

5.       
          Payment of the Exercise Price. The Holder shall pay the Exercise
          Price in the following manner: in cash at the time of exercise (a Cash
          Exercise).

6.       
          Anti-Dilution Adjustments; Distributions; Other Events. The
          Exercise Price and the number of Warrant Shares issuable hereunder shall be
          subject to adjustment from time to time as provided in this Paragraph 6. In
          the event that any adjustment of the Exercise Price or the number of Warrant
          Shares as required herein results in a fraction of a cent or fraction of a
          share, as applicable, such Exercise Price or number of Warrant Shares shall be
          rounded up or down to the nearest cent or share, as applicable.

| | A.       
               Subdivision or Combination of Common Stock. If the Company, at any
               time after the Issue Date, subdivides (by any stock split, stock dividend,
               recapitalization, reorganization, reclassification or otherwise) its shares of
               Common Stock into a greater number of shares, then after the date of record for
               effecting such subdivision, the Exercise Price in effect immediately prior to
               such subdivision will be proportionately reduced. If the Company, at any time
               after the initial issuance of this Warrant, combines (by reverse stock split,
               recapitalization, reorganization, reclassification or otherwise) its shares of
               Common Stock into a smaller number of shares, then, after the date of record for
               effecting such combination, the Exercise Price in effect immediately prior to
               such combination will be proportionally increased.

| | B.       
               Notice Of Adjustments. Upon the occurrence of each adjustment or
               readjustment of the Exercise Price resulting in a change in the Exercise Price
               by more than one percent (1%), or any change in the number or type of stock,
               securities and/or other property issuable upon exercise of this Warrant, the
               Company, at its expense, shall promptly compute such adjustment or readjustment
               or change and prepare and furnish to the Holder a certificate setting forth such
               adjustment or readjustment or change and showing in detail the facts upon which
               such adjustment or readjustment or change is based. The Company shall, upon the
               written request at any time of the Holder, furnish to the Holder a like
               certificate setting forth: (i) such adjustment or readjustment or change; (ii)
               the Exercise Price at the time in effect; and (iii) the number of shares of
               Common Stock and the amount, if any, of other securities or property which at
               the time would be received upon exercise of this Warrant.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | C.       
               Major Transactions. In the event of a merger, consolidation,
               business combination, tender offer, exchange of shares, recapitalization,
               reorganization, redemption or other similar event, as a result of which shares
               of Common Stock of the Company shall be changed into the same or a different
               number of shares of the same or another class or classes of stock or securities
               or other assets of the Company or another entity or the Company shall sell all
               or substantially all of its assets (each of the foregoing being a Major
               Transaction), the Company will give the Holder at least thirty (30)
               days written notice prior to the closing of such Major Transaction; provided,
               however, that the Company shall publicly disclose the terms of any such Major
               Transaction on or before the date on which it delivers notice of a Major
               Transaction to the Holder. Upon the occurrence of a Major Transaction: (i) the
               Holder shall be permitted to exercise this Warrant in whole or in part at any
               time prior to the record date for the receipt of such consideration and shall be
               entitled to receive, for each share of Common Stock issued to Holder for such
               exercise, the same per share consideration paid to the other holders of Common
               Stock in connection with such Major Transaction; and (ii) if and to the extent
               that the Holder retains any portion of this Warrant following such record date,
               the Company will cause the surviving or, in the event of a sale of assets,
               purchasing entity, as a condition precedent to such Major Transaction, to assume
               the obligations of the Company under this Warrant, with such adjustments to the
               Exercise Price and the securities covered hereby as are deemed appropriate by
               the Companys Board of Directors in order to preserve the economic benefits
               of this Warrant to the Holder.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | D.       
               Adjustments; Additional Shares, Securities or Assets. In the event
               that at any time, as a result of an adjustment made pursuant to this
               Paragraph 6, the Holder of this Warrant shall, upon exercise of this
               Warrant, become entitled to receive securities or assets (other than Common
               Stock) then, wherever appropriate, all references herein to shares of Common
               Stock shall be deemed to refer to and include such shares and/or other
               securities or assets; and thereafter the number of such shares and/or other
               securities or assets shall be subject to adjustment from time to time in a
               manner and upon terms as nearly equivalent as practicable to the provisions of
               this Paragraph 6. Any adjustment made herein other than pursuant to
               Paragraph 6 hereof that results in a decrease in the Exercise Price shall
               also effect a proportional increase in the number of shares of Common Stock into
               which this Warrant is exercisable.

7.       
           Fractional Interests. No fractional shares or scrip
          representing fractional shares shall be issuable upon the exercise of this
          Warrant, but on exercise of this Warrant, the Holder hereof may purchase only a
          whole number of shares of Common Stock. If, on exercise of this Warrant, the
          Holder hereof would be entitled to a fractional share of Common Stock or a right
          to acquire a fractional share of Common Stock, the Company shall, in lieu of
          issuing any such fractional share, pay to the Holder an amount in cash equal to
          the product resulting from multiplying such fraction by the Market Price as of
          the Exercise Date.

8.       
          Transfer of this Warrant. The Holder may sell, transfer, assign,
          pledge or otherwise dispose of this Warrant, in whole or in part, as long as
          such sale or other disposition is made pursuant to an effective registration
          statement or an exemption from the registration requirements of the Securities
          Act, and applicable state securities laws, and is otherwise made in accordance
          with the applicable provisions of the Securities Purchase Agreement. Upon such
          transfer or other disposition, the Holder shall deliver this Warrant to the
          Company together with a written notice to the Company, substantially in the form
          of the Transfer Notice attached hereto as Exhibit B (the
          Transfer Notice), indicating the person or persons to whom
          this Warrant shall be transferred and, if less than all of this Warrant is
          transferred, the number of Warrant Shares to be covered by the part of this
          Warrant to be transferred to each such person. Within three (3) Business Days of
          receiving a Transfer Notice and the original of this Warrant, the Company shall
          deliver to the each transferee designated by the Holder a Warrant or Warrants of
          like tenor and terms for the appropriate number of Warrant Shares and, if less
          than all this Warrant is transferred, shall deliver to the Holder a Warrant for
          the remaining number of Warrant Shares.

9.       
          Benefits of this Warrant. This Warrant shall be for the sole and
          exclusive benefit of the Holder of this Warrant and nothing in this Warrant
          shall be construed to confer upon any person other than the Holder of this
          Warrant any legal or equitable right, remedy or claim hereunder.

10.       
          Loss, theft, destruction or mutilation of Warrant. Upon receipt by
          the Company of evidence of the loss, theft, destruction or mutilation of this
          Warrant, and (in the case of loss, theft or destruction) of indemnity reasonably
          satisfactory to the Company, and upon surrender of this Warrant, if mutilated,
          the Company shall execute and deliver a new Warrant of like tenor and date.

11.       
          Notice or Demands. Any notice, demand or request
          required or permitted to be given by the Company or the Holder pursuant to the
          terms of this Warrant shall be in writing and shall be deemed delivered: (i)
          when delivered personally or by verifiable facsimile transmission, unless such
          delivery is made on a day that is not a Business Day, in which case such
          delivery will be deemed to be made on the next succeeding Business Day; (ii) on
          the next Business Day after timely delivery to an overnight courier; and (iii)
          on the Business Day actually received if deposited in the U.S. mail (certified
