1.
            DURATION
                AND EXERCISE OF WARRANTS





(a)  Exercise
      Period .
      The
      Holder may exercise this Warrant in whole or in part on any Business Day on
      or
      before 5:00 P.M., Eastern Daylight Time, on the Expiration Date, at which time
      this Warrant shall become void and of no value.




(b)  Exercise
      Procedures .





(i)  While
      this Warrant remains outstanding and exercisable in accordance with Section
      1(a) ,
      in
      addition to the manner set forth in Section 1(b)(ii) below, the Holder may
      exercise this Warrant in whole or in part at any
      time and from time to time by:





(A)  delivery
      to the Company of a duly executed copy of the Notice of Exercise attached as **Exhibit
      A** ;





(B)  surrender
      of this Warrant to the Secretary of the Company at its principal offices or
      at
      such other office or agency as the Company may specify in writing to the Holder;
      and





(C)  payment
      of the  then-applicable Exercise
      Price per share multiplied by the number of Warrant Shares being purchased
      upon
      exercise of the Warrant (such amount, the “ **Aggregate
      Exercise Price** ”) made
      in
      the form of cash, or by certified check, bank draft or money order payable
      in
      lawful money of the United States of America or in
      the form of a Cashless Exercise to the
      extent permitted in Section 1(b)( ii )
      below .





(ii)  While
      this Warrant remains outstanding and exercisable in accordance with Section
      1(a), the Holder may, in its sole discretion, exercise all or any part of the
      Warrant in a “cashless” or “net-issue” exercise (a “ **Cashless
      Exercise** ”)
      by
      delivering to the Company (1) the Notice of Exercise and (2) the original
      Warrant ,
      pursuant to which the Holder shall surrender the right to receive upon exercise
      of this Warrant, a number of Warrant Shares having a value (as determined below)
      equal to the Aggregate Exercise Price, in which case, the number of Warrant
      Shares to be issued to the Holder upon such exercise shall be calculated using
      the following formula:





X  =  Y
      * (A
      - B)


A





with:  X
      =  the
      number of Warrant Shares to be issued to the Holder





Y
      =  the
      number of Warrant Shares with respect to which the Warrant is being
      exercised





A
      =  the
      fair
      value per share of Common
      Stock on
      the
      date of exercise of this Warrant





B
      =  the
      then-current Exercise Price of
      the
      Warrant




2





Solely
      for the purposes of this paragraph, “fair value” per share of Common Stock shall
      be determined either (A) reasonably and in good faith by the Board of Directors
      of the Company as of the date which the Notice of Exercise is deemed to have
      been sent to the Company, or (B) as the average of the closing sales prices,
      as
      quoted on the primary national or regional stock exchange on which the Common
      Stock is listed, or ,
      if not
      listed, the NASD
      OTC Bulletin Board if quoted thereon, on the twenty ( 20 ) trading
      days immediately preceding the date on which the Notice of Exercise is deemed
      to
      have been sent to the Company, whichever of (A) or (B) is greater.





Notwithstanding
      the foregoing provisions of this Section 1(b), the Holder may not make a
      Cashless Exercise if and to the extent that such exercise would require the
      Company to issue a number of shares of Common Stock in excess of its authorized
      but unissued shares of Common Stock, less all amounts of Common Stock that
      have
      been reserved for issue upon the conversion of all outstanding securities
      convertible into shares of Common Stock and the exercise of all outstanding
      options, warrants and other rights exercisable for shares of Common Stock.
      If
      the Company does not have the requisite amount of authorized but unissued shares
      of Common Stock to permit the Holder to make a Cashless Exercise, the Company
      shall use its commercially best efforts to obtain the necessary stockholder
      consent to increase the authorized number of shares of Common Stock to permit
      such Holder to make a Cashless Exercise pursuant to this Section
      1(b).





(iii)  Upon
      th e  exercise of this
      Warrant in compliance with the provisions of this Section 1(b), and except
      as
      limited pursuant to the last paragraph of Section 1(b)(ii), the Company shall
      promptly issue and cause to be delivered to the Holder a certificate for the
      Warrant Shares purchased by the Holder. Each
      exercise of this Warrant shall be effective immediately prior to the close
      of
      business on the date (the “ **Date
      of Exercise** ”)
      which the
      conditions set forth in Section 1(b) have been satisfied, as the case may
      be . On
      the
      first Business Day following the date on which the Company has received each
      of
      the Exercise Notice and the Aggregate Exercise Price (or notice of a Cashless
      Exercise in accordance with Section 1(b)(ii)) (the “ **Exercise
      Delivery Documents** ”),
      the
      Company shall transmit an acknowledgment of receipt of the Exercise Delivery
      Documents to the Company’s transfer agent (the “ **Transfer
      Agent** ”).
      On or
      before the third Business Day following the date on which the Company has
      received all of the Exercise Delivery Documents (the “ **Share
      Delivery Date** ”),
      the
      Company shall (X) provided that the Transfer Agent is participating in The
      Depository Trust Company (“ **DTC** ”)
      Fast
      Automated Securities Transfer Program, upon the request of the Holder, credit
      such aggregate number of shares of Common Stock to which the Holder is entitled
      pursuant to such exercise to the Holder’s or its designee’s balance account with
      DTC through its Deposit Withdrawal Agent Commission system, or (Y) if the
      Transfer Agent is not participating in the DTC Fast Automated Securities
      Transfer Program, issue and dispatch by overnight courier to the address as
      specified in the Exercise Notice, a certificate, registered in the Company’s
      share register in the name of the Holder or its designee, for the number of
      shares of Common Stock to which the Holder is entitled pursuant to such
      exercise. Upon delivery of the Exercise Notice and Aggregate Exercise Price
      referred to in Section
      1(b)(i )(C) above or
      notification to the Company of a Cashless Exercise referred to in Section
      1(b)(ii), the Holder shall be deemed for all corporate purposes to have become
      the holder of record of the Warrant Shares with respect to which this Warrant
      has been exercised, irrespective of the date of delivery of the certificates
      evidencing such Warrant Shares. If this Warrant is submitted in connection
      with
      any exercise pursuant to Section 1(b) and the number of Warrant Shares
      represented by this Warrant submitted for exercise is greater than the actual number
      of
      Warrant Shares being acquired upon such **** an
      exercise, then the Company shall as soon as practicable and in no event later
      than three (3) Business Days after any exercise and at its own expense, issue
      a
      new Warrant (in accordance with Section 1(b)) of like
      tenor representing the right to purchase the number of Warrant Shares purchasable
      immediately prior to such exercise under this Warrant, less the number of
      Warrant Shares with respect to which this Warrant is exercised. No fractional
      shares of Common Stock are to be issued upon the exercise of this Warrant,
      but
      rather the number of shares of Common Stock to be issued shall be rounded up
      to
      the nearest whole number.

( iv)  If
      the
      Company shall fail for any reason or for no reason to issue to the Holder,
      within three (3) Business Days of receipt of the Exercise Delivery Documents,
      a
      certificate for the number of shares of Common Stock to which the Holder is
      entitled and register such shares of Common Stock on the Company’s share
      register or to credit the Holder’s balance account with DTC for such number of
      shares of Common Stock to which the Holder is entitled upon the Holder’s
      exercise of this Warrant, and if on or after such Business Day the Holder
      purchases (in an open market transaction or otherwise) shares of Common Stock
      to
      deliver in satisfaction of a sale by the Holder of shares of Common Stock
      issuable upon such exercise that the Holder anticipated receiving from the
      Company (a “ **Buy-In** ”),
      then
      the Company shall, within three (3) Business Days after the Holder’s request and
      in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal
      to the Holder’s total purchase price (including brokerage commissions, if any)
      for the shares of Common Stock so purchased (the “ **Buy-In
      Price** ”),
      at
      which point the Company’s obligation to deliver such certificate (and to issue
      such shares of Common Stock) shall terminate, or (ii) promptly honor its
      obligation to deliver to the Holder a certificate or certificates representing
      such shares of Common Stock and pay cash to the Holder in an amount equal to
      the
      excess (if any) of the Buy-In Price over the product of (A) such number of
      shares of Common Stock, times (B) the closing bid price on
      the
      date of exercise.





(c)  Partial
      Exercise .
      This
      Warrant shall be exercisable, either in its entirety or, from time to time,
      for
      part only of the number of Warrant Shares referenced by this Warrant. If this
      Warrant is exercised in part, the Company shall issue, at its expense, a new
      Warrant, in substantially the form of this Warrant, referencing such reduced
      number of Warrant Shares which remain subject to this Warrant.





(d)  Disputes .
      In the
      case of a dispute as to the determination of the Exercise Price or the
      arithmetic calculation of the Warrant Shares, the Company shall promptly issue
      to the Holder the number of Warrant Shares that are not disputed and resolve
      such dispute in accordance with Section 15.

            ISSUANCE
                OF WARRANT SHARES





(a)  The
      Company covenants that all Warrant Shares will, upon issuance in accordance
      with
      the terms of this Warrant, be (i) duly authorized, fully paid and
      non-assessable, and (ii) free from all liens, charges and security interests,
      with the exception of claims arising through the acts or omissions of any Holder
      and except as arising from applicable Federal and state securities
      laws.





(b)  The
      Company shall register this Warrant upon records to be maintained by the Company
      for that purpose in the name of the record holder of such Warrant from time
      to
      time. The Company may deem and treat the registered Holder of this Warrant
      as
      the absolute owner thereof for the purpose of any exercise thereof, any
      distribution to the Holder thereof and for all other purposes.





(c)  The
      Company will not, by amendment of its articles of incorporation, by-laws or
      through any reorganization, transfer of assets, consolidation, merger,
      dissolution, issue or sale of securities or any other voluntary action, avoid
      or
      seek to avoid the observance or performance of any of the terms to be observed
      or performed hereunder by the Company, but will at all times in good faith
      assist in the carrying out of all the provisions of this Warrant and in the
      taking of all the action as may be necessary or appropriate in order to protect
      the rights of the Holder to exercise this Warrant ,
      or
      against impairment of such rights .





3.
            ADJUSTMENTS
                OF EXERCISE PRICE, NUMBER AND TYPE OF WARRANT
                SHARES





(a)  The
      Exercise Price and the number of shares purchasable upon the exercise of this
      Warrant shall be subject to adjustment from time to time upon the occurrence
      of
      certain events described in this Section 3(a); provided ,
      that
      notwithstanding the provisions of this Section 3, the Company shall not be
      required to make any adjustment if and to the extent that such adjustment would
      require the Company to issue a number of shares of Common Stock in excess of
      its
      authorized but unissued shares of Common Stock, less all amounts of Common
      Stock
      that have been reserved for issue upon the conversion of all outstanding
      securities convertible into shares of Common Stock and the exercise of all
      outstanding options, warrants and other rights exercisable for shares of Common
      Stock. If the Company does not have the requisite amount of authorized but
      unissued shares of Common Stock to make any adjustment, the Company shall use
      its commercially best efforts to obtain the necessary stockholder consent to
      increase the authorized number of shares of Common Stock to permit the Holder
      to
      exercise fully this Warrant.





(i)  Subdivision
      or Combination of Stock .
      In case
      the Company shall at any time subdivide (whether
      by way of stock dividend, stock split or otherwise) its
      outstanding shares of Common Stock into a greater number of shares, the Exercise
      Price in effect immediately prior to such subdivision shall be proportionately
      reduced  and
      the
      Warrant Shares shall be proportionately increased ,
      and
      conversely, in case the outstanding shares of Common Stock of the Company shall
      be combined (whether
      by way of stock combination, reverse stock split or otherwise) into
      a
      smaller number of shares, the Exercise Price in effect immediately prior to
      such
      combination shall be proportionately increased and the
      number of Warrant Shares shall be proportionately decreased. The Exercise Price
      and the Warrant Shares, as so adjusted, shall be readjusted in the same manner
      upon the happening of any successive event or events described in this Section
      3(a)(i) .




5





(ii)  Dividends
      in Stock, Property, Reclassification .
      If at
      any time, or from time to time, the holders of Common Stock (or any shares
      of
      stock or other securities at the time receivable upon the exercise of this
      Warrant) shall have received or become entitled to receive, without payment
      therefore:





(A)  any
      shares of stock or other securities which are at any time directly or indirectly
      convertible into or exchangeable for Common Stock, or any rights or options
      to
      subscribe for, purchase or otherwise acquire any of the foregoing by way of
      dividend or other distribution, or





(B)  additional
      stock or other securities or property (including cash) by way of spin-off,
      split-up, reclassification, combination of shares or similar corporate
      rearrangement, (other than shares of Common Stock issued as a stock split or
      adjustments in respect of which shall be covered by the terms of Section 3(a)(i)
      above), then and in each such case, the Exercise
      Price and the number of Warrant Shares to be obtained upon exercise of this
      Warrant shall be adjusted proportionately, and the Holder
      hereof shall, upon the exercise of this Warrant, be entitled to receive, in
      addition to the number of shares of Common Stock receivable thereupon, and
      without payment of any additional consideration therefor, the amount of stock
      and other securities and property (including cash in the cases referred to
      above) which such Holder would hold on the date of such exercise had he been
      the
      holder of record of such Common Stock as of the date on which holders of Common
      Stock received or became entitled to receive such shares or all other additional
      stock and other securities and property. The
      Exercise Price and the Warrant Shares, as so adjusted, shall be readjusted
      in
      the same manner upon the happening of any successive event or events described
      in this Section 3(a)(ii) **.**





(iii)  Reorganization,
      Reclassification, Consolidation, Merger or Sale .
      If any
      recapitalization, reclassification or reorganization of the capital stock of
      the
      Company, or any consolidation or merger of the Company with another corporation,
      or the sale of all or substantially all of its assets or other
      transaction shall be effected in such a way that holders of Common Stock shall
      be entitled to receive stock, securities, or other assets or property (an
“ **Organic
      Change** ”),
      then,
      as a condition of such Organic Change, lawful and adequate provisions shall
      be
      made by the Company whereby the Holder hereof shall thereafter have the right
      to
      purchase and receive (in lieu of the shares of the Common Stock of the Company
      immediately theretofore purchasable and receivable upon the exercise of the
      rights represented by this Warrant) such shares of stock, securities or other
      assets or property as may be issued or payable with respect to or in exchange
      for a number of outstanding shares of such Common Stock equal to the number
      of
      shares of such stock immediately theretofore purchasable and receivable assuming
      the full exercise of the rights represented by this Warrant. In the event of
      any
      Organic Change, appropriate provision shall be made by the Company with respect
      to the rights and interests of the Holder of this Warrant to the end that the
      provisions hereof (including, without limitation, provisions for adjustments
      of
      the Exercise Price and of the number of shares purchasable and receivable upon
      the exercise of this Warrant) shall thereafter be applicable, in relation to
      any
      shares of stock, securities or assets thereafter deliverable upon the exercise
      hereof. The Company will not effect any such consolidation, merger or sale
      unless, prior to the consummation thereof, the successor corporation (if other
      than the Company) resulting from such consolidation or merger
      or the
      corporation purchasing such assets shall assume by written instrument reasonably
      satisfactory in form and substance to the Holders executed and mailed or
      delivered to the registered Holder hereof at the last address of such Holder
      appearing on the books of the Company, the obligation to deliver to such Holder
      such shares of stock, securities or assets as, in accordance
      with the foregoing provisions, such Holder may be entitled to
      purchase. **** If
      there
      is an Organic Change, then the Company shall cause to be mailed to the Holder
      at
      its last address as it shall appear on the books and records of the Company,
      at
      least 15 calendar days before the effective date of the Organic Change, a notice
      stating the date on which such Organic Change is expected to become effective
      or
      close, and the date as of which it is expected that holders of the Common Stock
      of record shall be entitled to exchange their shares for securities, cash,
      or
      other property delivered upon such Organic Change; provided ,
      that
      the failure to mail such notice or any defect therein or in the mailing thereof
      shall not affect the validity of the corporate action required to be specified
      in such notice. The Holder is entitled to exercise this Warrant during the
      15-day period commencing on the date of such notice to the effective date of
      the
      event triggering such notice. In
      any
      event, the successor corporation (if other than the Company) resulting from
      such
      consolidation or merger or the corporation purchasing such assets shall be
      deemed to assume such obligation to deliver to such Holder such shares of stock,
      securities or assets even in the absence of a written instrument assuming such
      obligation to the extent such assumption occurs by operation of law.

(b)  Certificate
      as to Adjustments .
      Upon
      the occurrence of each adjustment or readjustment pursuant to this Section
      3,
      the Company at its expense shall promptly compute such adjustment or
      readjustment in accordance with the terms hereof and furnish to each Holder
      of
      this Warrant a certificate setting forth such adjustment or readjustment and
      showing in detail the facts upon which such adjustment or readjustment is based.
      The Company shall promptly  furnish
      or cause to be furnished to such Holder a like certificate setting forth: (i)
      such adjustments and readjustments; and (ii) the number of shares and the
      amount, if any, of other property which at the time would be received upon
      the
      exercise of the Warrant.





(c)  Certain
      Events .
      If any
      event occurs as to which the other provisions of this Section 3 are not strictly
      applicable but the lack of any adjustment would not fairly protect the purchase
      rights of the Holder under this Warrant in accordance with the basic intent
      and

(d)  Adjustment
      of Exercise Price Upon Issuance of Additional Shares of Common
      Stock .
      In the
      event the
      Company shall at any time prior to the eighteenth month anniversary of the
      Effective Date issue Additional Shares of Common Stock, as defined below,
      without consideration or for a consideration per share less than the Exercise
      Price in effect immediately prior to such issue, then the Exercise Price shall
      be reduced, concurrently with such issue, to a price (calculated to the nearest
      cent) determined by multiplying such Exercise Price by a fraction, (A) the
      numerator of which shall be (1) the number of shares of Common Stock outstanding
      immediately prior to such issue plus (2) the number of shares of Common Stock
      which the aggregate consideration received or to be received by the Company
      for
      the total number of Additional Shares of Common Stock so issued would purchase
      at such Exercise Price; and (B) the denominator of which shall be the number
      of
      shares of Common Stock outstanding immediately prior to such issue plus the
      number of such Additional Shares of Common Stock so issued; provided that,
      (i) for the purpose of this Section 3(d), all shares of Common Stock issuable
      upon conversion or exchange of convertible securities outstanding immediately
      prior to such issue shall be deemed to be outstanding, and (ii) the number
      of
      shares of Common Stock deemed issuable upon conversion or exchange of such
      outstanding convertible securities shall be determined without giving effect
      to
      any adjustments to the conversion or exchange price or conversion or exchange
      rate of such convertible securities resulting from the issuance of Additional
      Shares of Common Stock that is the subject of this calculation. For purposes
      of
      this Warrant, “Additional Shares of Common Stock” shall mean all shares of
      Common Stock issued by the Company after the Effective Date (including without
      limitation any shares of Common Stock issuable upon conversion or exchange
      of
      any convertible securities or upon exercise of any option or warrant, on an
      as-converted basis), other than: (i) shares of Common Stock issued or
      issuable upon conversion or exchange of any convertible securities or exercise
      of any options outstanding on the Effective Date; (ii) shares of Common
      Stock issued or issuable by reason of a dividend, stock split, split-up or
      other
      distribution on shares of Common Stock that is covered by Sections 3(a)(i)
      through 3(a)(iii) above; or (iii) shares of Common Stock (or options with
      respect thereto) issued or issuable to employees or directors of, or consultants
      to, the Company or any of its subsidiaries pursuant to a plan, agreement or
      arrangement approved by the Board of Directors of the Company. The provisions
      of
      this Section 3(d) shall not operate to increase the Exercise Price.

      as a prerequisite to the issuance of a substitute Warrant, the Company may
      require satisfactory evidence of loss, theft or destruction as well as an
