    -2-
        3.    Registration
      of Transfers.
      The
      Company shall register the transfer of any portion of this Warrant in the
      Warrant Register, upon surrender of this Warrant, with the Form of Assignment

      acceptance of the New Warrant by the transferee thereof shall be deemed the
      acceptance by such transferee of all of the rights and obligations of a holder
      of a Warrant. 
    4.    Exercise
      and Duration of Warrants.
      
    (a)    This
      Warrant shall be exercisable by the registered Holder at any time and from
      time
      to time on or after the Initial Exercise Date through and including the
      Expiration Date. At 5:00 p.m., California time on the Expiration Date, the
      portion of this Warrant not exercised prior thereto shall be and become void
      and
      of no value. The Company may not call or redeem any portion of this Warrant
      without the prior written consent of the affected Holder.
    (b)    If
      at any
      time after the Initial Exercise Date there
      is
      no effective Registration Statement registering, or no current prospectus
      available for, the resale of the Warrant Shares by the Holder, then this Warrant
      may also be exercised at such time by means of a “cashless exercise” in which
      event the Company shall issue to the Holder the number of Warrant Shares
      determined as follows:
    X
      = Y
      [(A-B)/A]
    where:
    X
      = the
      number of Warrant Shares to be issued to the Holder.
    Y
      = the
      number of Warrant Shares with respect to which this Warrant is being
      exercised.
    A
      = the
      average of the closing sale prices for the five Business Days immediately prior
      to (but not including) the Exercise Date.
    B
      = the
      Exercise Price. 
    -3-
        (c)    The
      Holder shall not have the right to exercise any portion of this Warrant,
      pursuant to Section
      4(a)
      or
      otherwise, to the extent that after giving effect to such issuance after
      exercise, the Holder (together with the Holder’s Affiliates), as set forth on
      the applicable Exercise Notice, would beneficially own in excess of 4.99% of
      the
      number of shares of the Common Stock outstanding immediately after giving effect
      to such issuance. For purposes of the foregoing sentence, the number of shares
      of Common Stock beneficially owned by the Holder and its Affiliates shall
      include the number of shares of Common Stock issuable upon exercise of this
      Warrant with respect to which the determination of such sentence is being made,
      but shall exclude the number of shares of Common Stock which would be issuable
      upon (A) exercise of the remaining, nonexercised portion of this Warrant
      beneficially owned by the Holder or any of its Affiliates and (B) exercise
      or
      conversion of the unexercised or nonconverted portion of any other securities
      of
      the Company (including, without limitation, any other Warrants or Preferred
      Stock) subject to a limitation on conversion or exercise analogous to the
      limitation contained herein beneficially owned by the Holder or any of its
      Affiliates. Except as set forth in the preceding sentence, for purposes of
      this
Section
      4(c),
      beneficial ownership shall be calculated in accordance with Section 13(d) of
      the
      Exchange Act, it being acknowledged by Holder that the Company is not
      representing to Holder that such calculation is in compliance with Section
      13(d)
      of the Exchange Act and Holder is solely responsible for any schedules required
      to be filed in accordance therewith. To the extent that the limitation contained
      in this Section
      4(c)
      applies,
      the determination of whether this Warrant is exercisable (in relation to other
      securities owned by the Holder) and of which a portion of this Warrant is
      exercisable shall be in the sole discretion of such ▇▇▇▇▇▇, and the submission
      of a Exercise Notice shall be deemed to be such Holder’s determination of
      whether this Warrant is exercisable (in relation to other securities owned
      by
      such Holder) and of which portion of this Warrant is exercisable, in each case
      subject to such aggregate percentage limitation, and the Company shall have
      no
      obligation to verify or confirm the accuracy of such determination. For purposes
      of this Section
      4(c),
      in
      determining the number of outstanding shares of Common Stock, the Holder may
      rely on the number of outstanding shares of Common Stock as reflected in (x)
      the
      Company’s most recent Form 10-QSB or Form 10-KSB, as the case may be, (y) a more
      recent public announcement by the Company or (z) any other notice by the Company
      or the Company’s Transfer Agent setting forth the number of shares of Common
      Stock outstanding. Upon the written or oral request of the Holder, the Company
      shall within two (2) Business Days confirm orally and in writing to the Holder
      the number of shares of Common Stock then outstanding. In any case, the number
      of outstanding shares of Common Stock shall be determined after giving effect
      to
      the conversion or exercise of securities of the Company, including this Warrant,
      by the Holder or its Affiliates since the date as of which such number of
      outstanding shares of Common Stock was reported. The provisions of this
Section
      4(c)
      may be
      waived by the Holder, at the election of the Holder, upon not less than 61
      days’
prior notice to the Company, and the provisions of this Section
      4(c)
      shall
      continue to apply until such 61st day (or such later date, as determined by
      the
      Holder, as may be specified in such notice of waiver).
    5.    Delivery
      of Warrant Shares.
    (a)    To
      effect
      exercises hereunder, the Holder shall not be required to physically surrender
      this Warrant unless the aggregate Warrant Shares represented by this Warrant
      is
      being exercised. Upon delivery of the Exercise Notice (in the form attached
      hereto) to the Company (with the attached Warrant Shares Exercise Log) at its
      address for notice set forth herein and upon payment of the Exercise Price
      multiplied by the number of Warrant Shares that the Holder intends to purchase
      hereunder, the Company shall promptly (but in no event later than three (3)
      Business Days after the Date of Exercise (as defined herein)) issue and deliver
      to the Holder, a certificate for the Warrant Shares issuable upon such exercise,
      which, unless otherwise required by the Purchase Agreement, shall be free of
      restrictive legends. The Company shall, upon request of the Holder and
      subsequent to the date on which a registration statement covering the resale
      of
      the Warrant Shares has been declared effective by the SEC, use its reasonable
      best efforts to deliver Warrant Shares hereunder electronically through the
      Depository Trust Corporation or another established clearing corporation
      performing similar functions, if available, provided, that, the Company may,
      but
      will not be required to change its transfer agent if its current transfer agent
      cannot deliver Warrant Shares electronically through the Depository Trust
      Corporation. A “Date
      of Exercise”
means
      the date on which the Holder shall have delivered to the Company: (i) the
      Exercise Notice (with the Warrant Exercise Log attached to it), appropriately
      completed and duly signed and (ii) payment of the Exercise Price for the number
      of Warrant Shares so indicated by the Holder to be purchased.
    -4-
        (b)    If
      by the
      third (3rd)
      Business Day after a Date of Exercise the Company fails to deliver the required
      number of Warrant Shares in the manner required pursuant to Section 5(a),
      then
      the Holder will have the right to rescind such exercise.
    (c)    If
      by the
      third (3rd)
      Business Day after a Date of Exercise the Company fails to deliver the required
      number of Warrant Shares in the manner required pursuant to Section 5(a),
      and if
      after such third (3rd)
      Business Day and prior to the receipt of such Warrant Shares, 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 the Warrant Shares which
      the
      Holder anticipated receiving upon such exercise (a “Buy-In”),
      then
      the Company shall (1) pay in cash to the Holder the amount by which (x) the
      Holder’s total purchase price (including brokerage commissions, if any) for the
      shares of Common Stock so purchased exceeds (y) the amount obtained by
      multiplying (A) the number of Warrant Shares that the Company was required
      to
      deliver to the Holder in connection with the exercise at issue by (B) the
      closing sale price of the Common Stock at the time of the obligation giving
      rise
      to such purchase obligation and (2) at the option of the Holder, either
      reinstate the portion of the Warrant and equivalent number of Warrant Shares
      for
      which such exercise was not honored or deliver to the Holder the number of
      shares of Common Stock that would have been issued had the Company timely
      complied with its exercise and delivery obligations hereunder. The Holder shall
      provide the Company written notice and supporting documentation indicating
      the
      amounts payable to the Holder in respect of the Buy-In.
    (d)    The
      Company’s obligations to issue and deliver Warrant Shares in accordance with the
      terms hereof are absolute and unconditional, irrespective of any action or
      inaction by the Holder to enforce the same, any waiver or consent with respect
      to any provision hereof, the recovery of any judgment against any Person or
      any
      action to enforce the same, or any setoff, counterclaim, recoupment, limitation
      or termination, or any breach or alleged breach by the Holder or any other
      Person of any obligation to the Company or any violation or alleged violation
      of
      law by the Holder or any other Person, and irrespective of any other
      circumstance which might otherwise limit such obligation of the Company to
      the
      Holder in connection with the issuance of Warrant Shares. Nothing herein shall
      limit a ▇▇▇▇▇▇’s right to pursue any other remedies available to it hereunder,
      at law or in equity including, without limitation, a decree of specific
      performance and/or injunctive relief with respect to the Company’s failure to
      timely deliver certificates representing Warrant Shares upon exercise of the
      Warrant as required pursuant to the terms hereof.
    -5-
        6.    Charges,
      Taxes and Expenses.
      Issuance and delivery of Warrant Shares upon exercise of this Warrant shall
      be
      made without charge to the Holder for any issue or transfer tax, withholding
      tax, transfer agent fee or other incidental tax or expense in respect of the
      issuance of such certificates, all of which taxes and expenses shall be paid
      by
      the Company; provided,
      however,
      that
      the Company shall not be required to pay any tax which may be payable in respect
      of any transfer involved in the registration of any certificates for Warrant
      Shares or Warrants in a name other than that of the Holder. The Holder shall
      be
      responsible for all other tax liability that may arise as a result of holding
      or
      transferring this Warrant or receiving Warrant Shares upon exercise
      hereof.
    7.    Replacement
      of Warrant.
      If this
      Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or
      cause to be issued in exchange and substitution for and upon cancellation
      hereof, or in lieu of and substitution for this Warrant, a New Warrant, but
      only
      upon receipt of evidence reasonably satisfactory to the Company of such loss,
      theft or destruction and customary and reasonable indemnity (which shall not
      include a surety bond), if requested. Applicants for a New Warrant under such
      circumstances shall also comply with such other reasonable regulations and
      procedures and pay such other reasonable third-party costs as the Company may
      prescribe. If a New Warrant is requested as a result of a mutilation of this
      Warrant, then the Holder shall deliver such mutilated Warrant to the Company
      as
      a condition precedent to the Company’s obligation to issue the New
      Warrant.
    8.    Reservation
      of Warrant Shares.
      The
      Company covenants that it will at all times reserve and keep available out
      of
      the aggregate of its authorized but unissued and otherwise unreserved Common
      Stock, solely for the purpose of enabling it to issue Warrant Shares upon
      exercise of this Warrant as herein provided, the number of Warrant Shares which
      are then issuable and deliverable upon the exercise of this entire Warrant,
      free
      from preemptive rights or any other contingent purchase rights of Persons other
      than the Holder (taking into account the adjustments and restrictions of
Section 9).
      The
      Company covenants that all Warrant Shares so issuable and deliverable shall,
      upon issuance and the payment of the applicable Exercise Price in accordance
      with the terms hereof, be duly and validly authorized, issued and fully paid
      and
      nonassessable.
    9.    Certain
      Adjustments.
      The
      Exercise Price and number of Warrant Shares issuable upon exercise of this
      Warrant are subject to adjustment from time to time as set forth in this
Section 9.
    (a)    Stock
      Dividends and Splits.
      If the
      Company, at any time while this Warrant is outstanding, (i) pays a stock
      dividend on its Common Stock or otherwise makes a distribution on any class
      of
      capital stock that is payable in shares of Common Stock, (ii) subdivides
      outstanding shares of Common Stock into a larger number of shares, or (iii)
      combines outstanding shares of Common Stock into a smaller number of shares,
      then in each such case the Exercise Price shall be multiplied by a fraction
      of
      which the numerator shall be the number of shares of Common Stock outstanding
      immediately before such event and of which the denominator shall be the number
      of shares of Common Stock outstanding immediately after such event. Any
      adjustment made pursuant to clause (i) of this paragraph shall become effective
      immediately after the payment of the dividend or the making of the distribution,
      and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall
      become effective immediately after the effective date of such subdivision or
      combination.
    -6-
        (b)    Fundamental
      Transactions.
      If, at
      any time while this Warrant is outstanding there is a Fundamental Transaction,
      then the Holder shall have the right thereafter to receive, upon exercise of
      this Warrant, the same amount and kind of securities, cash or property as it
      would have been entitled to receive upon the occurrence of such Fundamental
      Transaction if it had been, immediately prior to such Fundamental Transaction,
      the holder of the number of Warrant Shares then issuable upon exercise in full
      of this Warrant (the “Alternate
      Consideration”).
      For
      purposes of any such exercise, the determination of the Exercise Price shall
      be
      appropriately adjusted to apply to such Alternate Consideration based on the
      amount of Alternate Consideration issuable in respect of one share of Common
      Stock in such Fundamental Transaction, and the Company shall apportion the
      Exercise Price among the Alternate Consideration in a reasonable manner
      reflecting the relative value of any different components of the Alternate
      Consideration. If holders of Common Stock are given any choice as to the
      securities, cash or property to be received in a Fundamental Transaction, then
      the Holder shall be given the same choice as to the Alternate Consideration
      it
      receives upon any exercise of this Warrant following such Fundamental
      Transaction. At the Holder’s option and request, any successor to the Company or
      surviving entity in such Fundamental Transaction shall issue to the Holder
      a new
      warrant substantially in the form of this Warrant and consistent with the
      foregoing provisions and evidencing the Holder’s right to purchase the Alternate
      Consideration for the aggregate Exercise Price upon exercise thereof. The terms
      of any agreement pursuant to which a Fundamental Transaction is effected shall
      include terms requiring any such successor or surviving entity to comply with
      the provisions of this paragraph (b) and insuring that the Warrant (or any
      such
      replacement security) will be similarly adjusted upon any subsequent transaction
      analogous to a Fundamental Transaction. 
    (c)    Number
      of Warrant Shares.
      Simultaneously with any adjustment to the Exercise Price pursuant to this
Section 9,
      the
      number of Warrant Shares that may be purchased upon exercise of this Warrant
      shall be increased or decreased proportionately, so that after such adjustment
      the aggregate Exercise Price payable hereunder for the adjusted number of
      Warrant Shares shall be the same as the aggregate Exercise Price in effect
      immediately prior to such adjustment.
    (d)    Calculations.
      All
      calculations under this Section 9
      shall be
      made to the nearest cent or the nearest 1/100th of a share, as applicable.
      The
      number of shares of Common Stock outstanding at any given time shall not include
      shares owned or held by or for the account of the Company, and the disposition
      of any such shares shall be considered an issue or sale of Common
      Stock.
    (e)    Notice
      of Adjustments.
      Upon
      the occurrence of each adjustment pursuant to this Section 9,
      the
      Company at its expense will promptly compute such adjustment in accordance
      with
      the terms of this Warrant and prepare a certificate setting forth such
      adjustment, including a statement of the adjusted Exercise Price and adjusted
      number or type of Warrant Shares or other securities issuable upon exercise
      of

    -7-
        (f)    Notice
      of Corporate Events.
      If the
      Company (i) declares a dividend or any other distribution of cash, securities
      or
      other property in respect of its Common Stock, including without limitation
      any
      granting of rights or warrants to subscribe for or purchase any capital stock
      of
      the Company or any Subsidiary, (ii) authorizes or approves, enters into any
      agreement contemplating or solicits shareholder approval for any Fundamental
      Transaction or (iii) authorizes the voluntary dissolution, liquidation or
      winding up of the affairs of the Company, then the Company shall deliver to
      the
      Holder a notice describing the material terms and conditions of such transaction
      (but only to the extent such disclosure would not result in the dissemination
      of
      material, non-public information to the Holder) at least ten (10) Business
      Days
      prior to the applicable record or effective date on which a Person would need
      to
      hold Common Stock in order to participate in or vote with respect to such
      transaction, and the Company will take all steps reasonably necessary in order
      to insure that the Holder is given the practical opportunity to exercise this
      Warrant prior to such time so as to participate in or vote with respect to
      such
      transaction; provided, however, that the failure to deliver such notice or
      any
      defect therein shall not affect the validity of the corporate action required
      to
      be described in such notice.
    (g)    Subsequent
      Equity Sales.
      If the
      Company at any time while this Warrant is outstanding, shall offer, sell, grant
      any option to purchase or offer, sell or grant any right to reprice its
      securities, or otherwise dispose of or issue (or announce any offer, sale,
      grant
      or any option to purchase or other disposition) any Common Stock or Common
      Stock
      Equivalents entitling any Person to acquire shares of Common Stock, at an
      effective price per share less than the then Exercise Price (each such issuance,
      a “Dilutive
      Issuance”),
      as
      adjusted hereunder (if the holder of the Common Stock or Common Stock
      Equivalents so issued shall at any time, whether by operation of purchase price
      adjustments, reset provisions, floating conversion, exercise or exchange prices
      or otherwise, or due to warrants, options or rights per share which is issued
      in
      connection with such issuance, be entitled to receive shares of Common Stock
      at
      an effective price per share which is less than the Exercise Price, such
      issuance shall be deemed to have occurred for less than the Exercise
      Price), then
      the
      Exercise Price shall be reduced to the price determined by dividing (x) an
      amount equal to the sum of (a) the number of shares of Common Stock outstanding
      immediately prior to such issue or sale multiplied by the then existing Exercise
      Price and (b) the consideration, if any, received by the Company upon such
      issue
      or sale, by (y) the total number of shares of Common Stock outstanding
      immediately after such issue or sale and, in each case, the number of Warrant
      Shares issuable hereunder shall be increased such that the aggregate Exercise
      Price payable hereunder, after taking into account the decrease in the Exercise
      Price, shall be equal to the aggregate Exercise Price prior to such adjustment.
      For purposes of determining the number of shares of Common Stock outstanding
      as
      provided in clauses (x) and (y) above, the number of shares of Common Stock
      issuable upon conversion of all outstanding Convertible Securities and exercise
      of all outstanding Options shall be deemed to be outstanding. Anything herein
      to
      the contrary notwithstanding, the Company shall not be required to make any
      adjustment of the Exercise Price in the case of the issuance or sale from and
      after the Original Issue Date of Anti-Dilution Excluded Securities. The Company
      shall notify the Holder in writing, no later than the Business Day following
      the
      issuance of any Common Stock or Common Stock Equivalents subject to this
      section, indicating therein the applicable issuance price, or of applicable
      reset price, exchange price, conversion price and other pricing terms (such
      notice the “Dilutive
      Issuance Notice”).

      the
      Holder shall pay the Exercise Price by delivering to the Company immediately
      available funds.
    11.    No
      Fractional Shares.
      No
      fractional shares of Warrant Shares will be issued in connection with any
      exercise of this Warrant. In lieu of any fractional shares which would,
      otherwise be issuable, the Company shall pay cash equal to the product of such
      fraction multiplied by the closing sale price of one Warrant Share as reported
      by the applicable Trading Market on the date of exercise.
