entitled to subscribe for and purchase, during the Term (as hereinafter

the provisions and upon the terms and conditions hereinafter set forth.
Capitalized terms used in this Warrant and not otherwise defined herein shall
have the respective meanings specified in Section 9 hereof.

      1. Term. The term of this Warrant shall commence on October 13, 2006 and
shall expire at 6:00 p.m., eastern time, on October 13, 2011; provided, however,
in the event that the Share Increase (as defined in the Purchase Agreement) has

term of this Warrant shall be automatically extended for a period of one (1)
year and the Issuer shall promptly issue to the Holder a new Warrant evidencing
the extension of such term (such period being the "Term").

Exchange.

                                      -1-

      (a) Time of Exercise. The purchase rights represented by this Warrant may
be exercised in whole or in part during the Term at any time following the
filing of the Charter Amendment (as defined in the Purchase Agreement) in
accordance with the terms of the Purchase Agreement for such number of shares of
Common Stock that have been exercised by the Holder pursuant to the Series J
Warrant issued by the Issuer to the Holder pursuant to the Purchase Agreement.

      (b) Method of Exercise. The Holder hereof may exercise this Warrant, in
whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto duly executed) at the principal office of the Issuer, and by the
payment to the Issuer of an amount of consideration therefor equal to the
Warrant Price in effect on the date of such exercise multiplied by the number of
shares of Warrant Stock with respect to which this Warrant is then being
exercised, payable at such Holder's election (i) by certified or official bank
check or by wire transfer to an account designated by the Issuer, (ii) by
"cashless exercise" in accordance with the provisions of subsection (c) of this
Section 2, but only when a registration statement under the Securities Act
providing for the resale of the Warrant Stock is not then in effect, or (iii) by
a combination of the foregoing methods of payment selected by the Holder of this
Warrant.

      (c) Cashless Exercise. Notwithstanding any provisions herein to the
contrary and commencing one (1) year following the Original Issue Date if (i)
the Per Share Market Value of one share of Common Stock is greater than the
Warrant Price (at the date of calculation as set forth below) and (ii) a
registration statement under the Securities Act providing for the resale of the
Warrant Stock is not then in effect by the date such registration statement is
required to be effective pursuant to the Registration Rights Agreement (as
defined in the Purchase Agreement) or not effective at any time during the
Effectiveness Period (as defined in the Registration Rights Agreement) in
accordance with the terms of the Registration Rights Agreement, unless the
registration statement is not effective as a result of the Issuer exercising its
rights under Section 3(n) of the Registration Rights Agreement, in lieu of
exercising this Warrant by payment of cash, the Holder may exercise this Warrant
by a cashless exercise and shall receive the number of shares of Common Stock
equal to an amount (as determined below) by surrender of this Warrant at the
principal office of the Issuer together with the properly endorsed Notice of
Exercise in which event the Issuer shall issue to the Holder a number of shares
of Common Stock computed using the following formula:

         X = Y - (A)(Y)
                 -----
                    B

Where    X =    the number of shares of Common Stock to be issued to the Holder.

         Y =    the number of shares of Common Stock purchasable
                upon exercise of all of the Warrant or, if only a
                portion of the Warrant is being exercised, the
                portion of the Warrant being exercised.

         A =    the Warrant Price.

         B =    the Per Share Market Value of one share of Common Stock.

                                      -2-
<PAGE>

      (d) Issuance of Stock Certificates. In the event of any exercise of this
Warrant in accordance with and subject to the terms and conditions hereof,
certificates for the shares of Warrant Stock so purchased shall be dated the
date of such exercise and delivered to the Holder hereof within a reasonable
time, not exceeding three (3) Trading Days after such exercise (the "Delivery
Date") or, at the request of the Holder (provided that a registration statement
under the Securities Act providing for the resale of the Warrant Stock is then
in effect or that the shares of Warrant Stock are otherwise exempt from
registration), issued and delivered to the Depository Trust Company ("DTC")
account on the Holder's behalf via the Deposit Withdrawal Agent Commission
System ("DWAC") within a reasonable time, not exceeding three (3) Trading Days
after such exercise, and the Holder hereof shall be deemed for all purposes to
be the holder of the shares of Warrant Stock so purchased as of the date of such
exercise. Notwithstanding the foregoing to the contrary, the Issuer or its
transfer agent shall only be obligated to issue and deliver the shares to the
DTC on a holder's behalf via DWAC if such exercise is in connection with a sale
or other exemption from registration by which the shares may be issued without a
restrictive legend and the Issuer and its transfer agent are participating in
DTC through the DWAC system. The Holder shall deliver this original Warrant, or
an indemnification reasonably acceptable to the Issuer undertaking with respect
to such Warrant in the case of its loss, theft or destruction, at such time that
this Warrant is fully exercised. With respect to partial exercises of this
Warrant, the Issuer shall keep written records for the Holder of the number of
shares of Warrant Stock exercised as of each date of exercise.

      (e) Compensation for Buy-In on Failure to Timely Deliver Certificates Upon
Exercise. In addition to any other rights available to the Holder, if the Issuer
fails to cause its transfer agent to transmit to the Holder a certificate or
certificates representing the Warrant Stock pursuant to an exercise on or before
the Delivery Date, and if after such date the Holder is required by its broker
to purchase (in an open market transaction or otherwise) shares of Common Stock
to deliver in satisfaction of a sale by the Holder of the Warrant Stock which
the Holder anticipated receiving upon such exercise (a "Buy-In"), then the
Issuer 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 shares of Warrant Stock that the Issuer was required to deliver to the
Holder in connection with the exercise at issue times (B) the price at which the
sell order giving rise to such purchase obligation was executed, and (2) at the
option of the Holder, either reinstate the portion of the Warrant and equivalent
number of shares of Warrant Stock 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 Issuer timely complied with its exercise and delivery obligations
hereunder. For example, if the Holder purchases Common Stock having a total
purchase price of $11,000 to cover a Buy-In with respect to an attempted
exercise of shares of Common Stock with an aggregate sale price giving rise to
such purchase obligation of $10,000, under clause (1) of the immediately
preceding sentence the Issuer shall be required to pay the Holder $1,000. The
Holder shall provide the Issuer written notice indicating the amounts payable to
the Holder in respect of the Buy-In, together with applicable confirmations and
other evidence reasonably requested by the Issuer. Nothing herein shall limit a
Holder'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 Issuer's failure to timely deliver
certificates representing shares of Common Stock upon exercise of this Warrant
as required pursuant to the terms hereof.

      (f) Transferability of Warrant. Subject to Section 2(h) hereof, this
Warrant may be transferred by a Holder, in whole or in part, without the consent
of the Issuer. If transferred pursuant to this paragraph, this Warrant may be
transferred on the books of the Issuer by the Holder hereof in person or by duly
authorized attorney, upon surrender of this Warrant at the principal office of
the Issuer, properly endorsed (by the Holder executing an assignment in the form
attached hereto) and upon payment of any necessary transfer tax or other
governmental charge imposed upon such transfer. This Warrant is exchangeable at
the principal office of the Issuer for Warrants to purchase the same aggregate
number of shares of Warrant Stock, each new Warrant to represent the right to
purchase such number of shares of Warrant Stock as the Holder hereof shall
designate at the time of such exchange. All Warrants issued on transfers or
exchanges shall be dated the Original Issue Date and shall be identical with
this Warrant except as to the number of shares of Warrant Stock issuable
pursuant thereto.

      (g) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such Holder shall fail to make any such request, the
failure shall not affect the continuing obligation of the Issuer to afford such
rights to such Holder.

      (h) Compliance with Securities Laws.

            (i) The Holder of this Warrant, by acceptance hereof, acknowledges
      that this Warrant and the shares of Warrant Stock to be issued upon
      exercise hereof are being acquired solely for the Holder's own account and
      not as a nominee for any other party, and for investment, and that the
      Holder will not offer, sell or otherwise dispose of this Warrant or any
      shares of Warrant Stock to be issued upon exercise hereof except pursuant
      to an effective registration statement, or an exemption from registration,
      under the Securities Act and any applicable state securities laws.

            (ii) Except as provided in paragraph (iii) below, this Warrant and
      all certificates representing shares of Warrant Stock issued upon exercise
      hereof shall be stamped or imprinted with a legend in substantially the
      following form:

            THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE
            HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
            AMENDED (THE "SECURITIES ACT") OR ANY STATE SECURITIES LAWS AND MAY
            NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED
            UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES LAWS
            OR THE ISSUER SHALL HAVE RECEIVED AN OPINION OF COUNSEL REASONABLY
            SATISFACTORY TO THE ISSUER THAT REGISTRATION OF SUCH SECURITIES
            UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE
            STATE SECURITIES LAWS IS NOT REQUIRED.

                                      -4-

            (iii) The Issuer agrees to reissue this Warrant or certificates
      representing any of the Warrant Stock, without the legend set forth above
      if at such time, prior to making any transfer of any such securities, the
      Holder shall give written notice to the Issuer describing the manner and
      terms of such transfer. Such proposed transfer will not be effected until:
      (a) either (i) the Issuer has received an opinion of counsel reasonably
      satisfactory to the Issuer, to the effect that the registration of such
      securities under the Securities Act is not required in connection with
      such proposed transfer, (ii) a registration statement under the Securities
      Act covering such proposed disposition has been filed by the Issuer with
      the Securities and Exchange Commission and has become effective under the
      Securities Act, (iii) the Issuer has received other evidence reasonably
      satisfactory to the Issuer that such registration and qualification under
      the Securities Act and state securities laws are not required, or (iv) the
      Holder provides the Issuer with reasonable assurances that such security
      can be sold pursuant to Rule 144 under the Securities Act; and (b) either
      (i) the Issuer has received an opinion of counsel reasonably satisfactory
      to the Issuer, to the effect that registration or qualification under the
      securities or "blue sky" laws of any state is not required in connection
      with such proposed disposition, or (ii) compliance with applicable state
      securities or "blue sky" laws has been effected or a valid exemption
      exists with respect thereto. The Issuer will respond to any such notice
      from a holder within three (3) Trading Days. In the case of any proposed
      transfer under this Section 2(h), the Issuer will use reasonable efforts
      to comply with any such applicable state securities or "blue sky" laws,
      but shall in no event be required, (x) to qualify to do business in any
      state where it is not then qualified, (y) to take any action that would
      subject it to tax or to the general service of process in any state where
      it is not then subject, or (z) to comply with state securities or "blue
      sky" laws of any state for which registration by coordination is
      unavailable to the Issuer. The restrictions on transfer contained in this
      Section 2(h) shall be in addition to, and not by way of limitation of, any
      other restrictions on transfer contained in any other section of this
      Warrant. Whenever a certificate representing the Warrant Stock is required
      to be issued to a the Holder without a legend, in lieu of delivering
      physical certificates representing the Warrant Stock, the Issuer shall
      cause its transfer agent to electronically transmit the Warrant Stock to
      the Holder by crediting the account of the Holder or Holder's Prime Broker
      with DTC through its DWAC system (to the extent not inconsistent with any
      provisions of this Warrant or the Purchase Agreement).

      (i) Accredited Investor Status. In no event may the Holder exercise this
Warrant in whole or in part unless the Holder is an "accredited investor" as
defined in Regulation D under the Securities Act.

      3. Stock Fully Paid; Reservation and Listing of Shares; Covenants.

      (a) Stock Fully Paid. The Issuer represents, warrants, covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, when issued in accordance with the
terms of this Warrant, be duly authorized, validly issued, fully paid and
non-assessable and free from all taxes, liens and charges created by or through
the Issuer. The Issuer further covenants and agrees that during the period
within which this Warrant may be exercised, the Issuer will at all times have
authorized and reserved for the purpose of the issuance upon exercise of this
Warrant a number of authorized but unissued shares of Common Stock equal to at
least one hundred fifty (150%) of the number of shares of Common Stock issuable
upon exercise of this Warrant without regard to any limitations on exercise.

      (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any Governmental Authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, and maintain and increase when necessary such listing,
of, all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder (provided that such Warrant Stock has
been registered pursuant to a registration statement under the Securities Act
then in effect), and, to the extent permissible under the applicable securities
exchange rules, all unissued shares of Warrant Stock which are at any time
issuable hereunder, so long as any shares of Common Stock shall be so listed.
The Issuer will also so list on each securities exchange or market, and will
maintain such listing of, any other securities which the Holder of this Warrant
shall be entitled to receive upon the exercise of this Warrant if at the time
any securities of the same class shall be listed on such securities exchange or
market by the Issuer.

      (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Articles of Incorporation or the by-laws of the Issuer,
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other action, avoid or seek to
avoid the observance or performance of any of the terms of this Warrant, but
will at all times in good faith assist in the carrying out of all such terms and
in the taking of all such actions as may be necessary or appropriate to protect
the rights of the Holder hereof against dilution (to the extent specifically
provided herein) or impairment. Without limiting the generality of the
foregoing, the Issuer will (i) not permit the par value, if any, of its Common
Stock to exceed the then effective Warrant Price, (ii) not amend or modify any
provision of the Articles of Incorporation or by-laws of the Issuer in any
manner that would adversely affect the rights of the Holders of the Warrants,
(iii) take all such action as may be reasonably necessary in order that the
Issuer may validly and legally issue fully paid and nonassessable shares of
Common Stock, free and clear of any liens, claims, encumbrances and restrictions
(other than as provided herein) upon the exercise of this Warrant, and (iv) use
its best efforts to obtain all such authorizations, exemptions or consents from
any public regulatory body having jurisdiction thereof as may be reasonably
necessary to enable the Issuer to perform its obligations under this Warrant.

                                      -6-
<PAGE>

      (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

      (e) Payment of Taxes. The Issuer will pay any documentary stamp taxes
attributable to the initial issuance of the Warrant Stock issuable upon exercise
of this Warrant; provided, however, that the Issuer shall not be required to pay
any tax or taxes which may be payable in respect of any transfer involved in the
issuance or delivery of any certificates representing Warrant Stock in a name
other than that of the Holder in respect to which such shares are issued.

      4. Adjustment of Warrant Price. The price at which such shares of Warrant
Stock may be purchased upon exercise of this Warrant shall be subject to
adjustment from time to time as set forth in this Section 4. The Issuer shall
give the Holder notice of any event described below which requires an adjustment
pursuant to this Section 4 in accordance with the notice provisions set forth in
Section 5.

      (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale.

            (i) In case the Issuer after the Original Issue Date shall do any of
      the following (each, a "Triggering Event"): (a) consolidate or merge with
      or into any other Person and the Issuer shall not be the continuing or
      surviving corporation of such consolidation or merger, or (b) permit any
      other Person to consolidate with or merge into the Issuer and the Issuer
      shall be the continuing or surviving Person but, in connection with such
      consolidation or merger, any Capital Stock of the Issuer shall be changed
      into or exchanged for Securities of any other Person or cash or any other
      property, or (c) transfer all or substantially all of its properties or
      assets to any other Person, or (d) effect a capital reorganization or
      reclassification of its Capital Stock, then, and in the case of each such
      Triggering Event, proper provision shall be made to the Warrant Price and
      the number of shares of Warrant Stock that may be purchased upon exercise
      of this Warrant so that, upon the basis and the terms and in the manner
      provided in this Warrant, the Holder of this Warrant shall be entitled
      upon the exercise hereof at any time after the consummation of such
      Triggering Event, to the extent this Warrant is not exercised prior to
      such Triggering Event, to receive at the Warrant Price as adjusted to take
      into account the consummation of such Triggering Event, in lieu of the
      Common Stock issuable upon such exercise of this Warrant prior to such
      Triggering Event, the Securities, cash and property to which such Holder
      would have been entitled upon the consummation of such Triggering Event if
      such Holder had exercised the rights represented by this Warrant
      immediately prior thereto (including the right of a shareholder to elect
      the type of consideration it will receive upon a Triggering Event),
      subject to adjustments (subsequent to such corporate action) as nearly
      equivalent as possible to the adjustments provided for elsewhere in this
      Section 4, and the Warrant Price shall be adjusted to equal the product of

                                      -7-
<PAGE>

      (A) the closing price of the common stock of the continuing or surviving
      corporation as a result of such Triggering Event as of the date
      immediately preceding the date of the consummation of such Triggering
      Event multiplied by (B) the quotient of (i) the Warrant Price divided by
      (ii) the Per Share Market Value of the Common Stock as of the date
      immediately preceding the Original Issue Date; provided, however, the
      Holder at its option may elect to receive an amount in cash equal to the
      value of this Warrant calculated in accordance with the Black-Scholes
      formula. Immediately upon the occurrence of a Triggering Event, the Issuer
      shall notify the Holder in writing of such Triggering Event and provide
      the calculations in determining the number of shares of Warrant Stock
      issuable upon exercise of the new warrant and the adjusted Warrant Price.
      Upon the Holder's request, the continuing or surviving corporation as a
      result of such Triggering Event shall issue to the Holder a new warrant of
      like tenor evidencing the right to purchase the adjusted number of shares
      of Warrant Stock and the adjusted Warrant Price pursuant to the terms and
      provisions of this Section 4(a)(i). Notwithstanding the foregoing to the
      contrary, this Section 4(a)(i) shall only apply if the surviving entity
      pursuant to any such Triggering Event is a company that has a class of
      equity securities registered pursuant to the Securities Exchange Act of
      1934, as amended, and its common stock is listed or quoted on a national
      securities exchange, national automated quotation system or the OTC
      Bulletin Board. In the event that the surviving entity pursuant to any
      such Triggering Event is not a public company that is registered pursuant
      to the Securities Exchange Act of 1934, as amended, or its common stock is
      not listed or quoted on a national securities exchange, national automated
      quotation system or the OTC Bulletin Board, then the Holder shall have the
      right to demand that the Issuer pay to the Holder an amount in cash equal
      to the value of this Warrant calculated in accordance with the
      Black-Scholes formula.

            (ii) In the event that the Holder has elected not to exercise this
      Warrant prior to the consummation of a Triggering Event and has also
      elected not to receive an amount in cash equal to the value of this
      Warrant calculated in accordance with the Black-Scholes formula pursuant
      to the provisions of Section 4(a)(i) above, so long as the surviving
      entity pursuant to any Triggering Event is a company that has a class of
      equity securities registered pursuant to the Securities Exchange Act of
      1934, as amended, and its common stock is listed or quoted on a national
      securities exchange, national automated quotation system or the OTC
      Bulletin Board, the surviving entity and/or each Person (other than the
      Issuer) which may be required to deliver any Securities, cash or property
      upon the exercise of this Warrant as provided herein shall assume, by
      written instrument delivered to, and reasonably satisfactory to, the
      Holder of this Warrant, (A) the obligations of the Issuer under this
      Warrant (and if the Issuer shall survive the consummation of such
      Triggering Event, such assumption shall be in addition to, and shall not
      release the Issuer from, any continuing obligations of the Issuer under
      this Warrant) and (B) the obligation to deliver to such Holder such
      Securities, cash or property as, in accordance with the foregoing
      provisions of this subsection (a), such Holder shall be entitled to
      receive, and the surviving entity and/or each such Person shall have
      similarly delivered to such Holder an opinion of counsel for the surviving
      entity and/or each such Person, which counsel shall be reasonably
      satisfactory to such Holder, or in the alternative, a written
      acknowledgement executed by the President or Chief Financial Officer of
      the Issuer, stating that this Warrant shall thereafter continue in full
      force and effect and the terms hereof (including, without limitation, all
      of the provisions of this subsection (a)) shall be applicable to the
      Securities, cash or property which the surviving entity and/or each such
      Person may be required to deliver upon any exercise of this Warrant or the
      exercise of any rights pursuant hereto.

                                      -8-
<PAGE>

      (b) Stock Dividends, Subdivisions and Combinations. If at any time the
Issuer shall:

            (i) make or issue or set a record date for the holders of the Common
      Stock for the purpose of entitling them to receive a dividend payable in,
      or other distribution of, shares of Common Stock,

            (ii) subdivide its outstanding shares of Common Stock into a larger
      number of shares of Common Stock, or

            (iii) combine its outstanding shares of Common Stock into a smaller
      number of shares of Common Stock,

then (1) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the occurrence of such event would own or be entitled to
receive after the happening of such event, and (2) the Warrant Price then in
effect shall be adjusted to equal (A) the Warrant Price then in effect
multiplied by the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to the adjustment divided by (B) the number of
shares of Common Stock for which this Warrant is exercisable immediately after
such adjustment.

      (c) Certain Other Distributions. If at any time the Issuer shall make or
issue or set a record date for the holders of the Common Stock for the purpose
of entitling them to receive any dividend or other distribution of:

            (i) cash (other than a cash dividend payable out of earnings or
      earned surplus legally available for the payment of dividends under the
      laws of the jurisdiction of incorporation of the Issuer),

            (ii) any evidences of its indebtedness, any shares of stock of any
      class or any other securities or property of any nature whatsoever (other
      than cash, Common Stock Equivalents or Additional Shares of Common Stock),
      or

            (iii) any warrants or other rights to subscribe for or purchase any
      evidences of its indebtedness, any shares of stock of any class or any
      other securities or property of any nature whatsoever (other than cash,
      Common Stock Equivalents or Additional Shares of Common Stock),

                                      -9-
<PAGE>

then (1) the number of shares of Common Stock for which this Warrant is
exercisable shall be adjusted to equal the product of the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to such
adjustment multiplied by a fraction (A) the numerator of which shall be the Per
Share Market Value of Common Stock at the date of taking such record and (B) the
denominator of which shall be such Per Share Market Value minus the amount
allocable to one share of Common Stock of any such cash so distributable and of
the fair value (as determined in good faith by the Board of Directors of the
Issuer and supported by an opinion from an investment banking firm mutually
agreed upon by the Issuer and the Holder) of any and all such evidences of
indebtedness, shares of stock, other securities or property or warrants or other
subscription or purchase rights so distributable, and (2) the Warrant Price then
in effect shall be adjusted to equal (A) the Warrant Price then in effect
multiplied by the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to the adjustment divided by (B) the number of
shares of Common Stock for which this Warrant is exercisable immediately after
such adjustment. A reclassification of the Common Stock (other than a change in
par value, or from par value to no par value or from no par value to par value)
into shares of Common Stock and shares of any other class of stock shall be
deemed a distribution by the Issuer to the holders of its Common Stock of such
shares of such other class of stock within the meaning of this Section 4(c) and,
if the outstanding shares of Common Stock shall be changed into a larger or
smaller number of shares of Common Stock as a part of such reclassification,
such change shall be deemed a subdivision or combination, as the case may be, of
the outstanding shares of Common Stock within the meaning of Section 4(b).

      (d) Issuance of Additional Shares of Common Stock. In the event the Issuer
shall at any time following the Original Issuance Date issue any Additional
Shares of Common Stock (otherwise than as provided in the foregoing subsections
(b) through (c) of this Section 4), at a price per share less than the Warrant
Price then in effect or without consideration, then the Warrant Price upon each
such issuance shall be adjusted to the price equal to the consideration per
share paid for such Additional Shares of Common Stock.

      (e) Issuance of Common Stock Equivalents. In the event the Issuer shall at
any time following the Original Issuance Date take a record of the holders of
its Common Stock for the purpose of entitling them to receive a distribution of,
or shall in any manner (whether directly or by assumption in a merger in which
the Issuer is the surviving corporation) issue or sell, any Common Stock
Equivalents, whether or not the rights to exchange or convert thereunder are
immediately exercisable, and the price per share for which Common Stock is
issuable upon such conversion or exchange shall be less than the Warrant Price
in effect immediately prior to the time of such issue or sale, or if, after any
such issuance of Common Stock Equivalents, the price per share for which
Additional Shares of Common Stock may be issuable thereafter is amended or
adjusted, and such price as so amended shall be less than the Warrant Price in
effect at the time of such amendment or adjustment, then the Warrant Price then
in effect shall be adjusted as provided in Section 4(d). No further adjustments
of the number of shares of Common Stock for which this Warrant is exercisable
and the Warrant Price then in effect shall be made upon the actual issue of such
Common Stock upon conversion or exchange of such Common Stock Equivalents.

      (f) Other Provisions applicable to Adjustments under this Section. The
following provisions shall be applicable to the making of adjustments of the
number of shares of Common Stock for which this Warrant is exercisable and the
Warrant Price then in effect provided for in this Section 4:

                                      -10-
<PAGE>

            (i) Computation of Consideration. To the extent that any Additional
      Shares of Common Stock or any Common Stock Equivalents (or any warrants or
      other rights therefor) shall be issued for cash consideration, the
      consideration received by the Issuer therefor shall be the amount of the
      cash received by the Issuer therefor, or, if such Additional Shares of
      Common Stock or Common Stock Equivalents are offered by the Issuer for
      subscription, the subscription price, or, if such Additional Shares of
      Common Stock or Common Stock Equivalents are sold to underwriters or
      dealers for public offering without a subscription offering, the initial
      public offering price (in any such case subtracting any amounts paid or
      receivable for accrued interest or accrued dividends and without taking
      into account any compensation, discounts or expenses paid or incurred by
      the Issuer for and in the underwriting of, or otherwise in connection
      with, the issuance thereof). In connection with any merger or
      consolidation in which the Issuer is the surviving corporation (other than
      any consolidation or merger in which the previously outstanding shares of
      Common Stock of the Issuer shall be changed to or exchanged for the stock
      or other securities of another corporation), the amount of consideration
      therefore shall be, deemed to be the fair value, as determined reasonably
      and in good faith by the Board, of such portion of the assets and business
      of the nonsurviving corporation as the Board may determine to be
      attributable to such shares of Common Stock or Common Stock Equivalents,
      as the case may be. The consideration for any Additional Shares of Common
      Stock issuable pursuant to any warrants or other rights to subscribe for
      or purchase the same shall be the consideration received by the Issuer for
      issuing such warrants or other rights plus the additional consideration
      payable to the Issuer upon exercise of such warrants or other rights. The
      consideration for any Additional Shares of Common Stock issuable pursuant
      to the terms of any Common Stock Equivalents shall be the consideration
      received by the Issuer for issuing warrants or other rights to subscribe
      for or purchase such Common Stock Equivalents, plus the consideration paid
      or payable to the Issuer in respect of the subscription for or purchase of
      such Common Stock Equivalents, plus the additional consideration, if any,
      payable to the Issuer upon the exercise of the right of conversion or
      exchange in such Common Stock Equivalents. In the event of any
      consolidation or merger of the Issuer in which the Issuer is not the
      surviving corporation or in which the previously outstanding shares of
      Common Stock of the Issuer shall be changed into or exchanged for the
      stock or other securities of another corporation, or in the event of any
      sale of all or substantially all of the assets of the Issuer for stock or
      other securities of any corporation, the Issuer shall be deemed to have
      issued a number of shares of its Common Stock for stock or securities or
      other property of the other corporation computed on the basis of the
      actual exchange ratio on which the transaction was predicated, and for a
      consideration equal to the fair market value on the date of such
      transaction of all such stock or securities or other property of the other
      corporation. In the event any consideration received by the Issuer for any
      securities consists of property other than cash, the fair market value
      thereof at the time of issuance or as otherwise applicable shall be as
      determined in good faith by the Board. In the event Common Stock is issued
      with other shares or securities or other assets of the Issuer for
      consideration which covers both, the consideration computed as provided in
      this Section 4(f)(i) shall be allocated among such securities and assets
      as determined in good faith by the Board.

            (ii) When Adjustments to Be Made. The adjustments required by this
      Section 4 shall be made whenever and as often as any specified event
      requiring an adjustment shall occur, except that any adjustment of the
      number of shares of Common Stock for which this Warrant is exercisable
      that would otherwise be required may be postponed (except in the case of a
      subdivision or combination of shares of the Common Stock, as provided for
      in Section 4(b)) up to, but not beyond the date of exercise if such
      adjustment either by itself or with other adjustments not previously made
      adds or subtracts less than one percent (1%) of the shares of Common Stock
      for which this Warrant is exercisable immediately prior to the making of
      such adjustment. Any adjustment representing a change of less than such
      minimum amount (except as aforesaid) which is postponed shall be carried
      forward and made as soon as such adjustment, together with other
      adjustments required by this Section 4 and not previously made, would
      result in a minimum adjustment or on the date of exercise. For the purpose
      of any adjustment, any specified event shall be deemed to have occurred at
      the close of business on the date of its occurrence.

                                      -11-
<PAGE>

            (iii) Fractional Interests. In computing adjustments under this
      Section 4, fractional interests in Common Stock shall be taken into
      account to the nearest one one-hundredth (1/100th) of a share.

            (iv) When Adjustment Not Required. If the Issuer shall take a record
      of the holders of its Common Stock for the purpose of entitling them to
      receive a dividend or distribution or subscription or purchase rights and
      shall, thereafter and before the distribution to stockholders thereof,
      legally abandon its plan to pay or deliver such dividend, distribution,
      subscription or purchase rights, then thereafter no adjustment shall be
      required by reason of the taking of such record and any such adjustment
      previously made in respect thereof shall be rescinded and annulled.

      (g) Form of Warrant after Adjustments. The form of this Warrant need not
be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

      (h) Escrow of Warrant Stock. If after any property becomes distributable
pursuant to this Section 4 by reason of the taking of any record of the holders
of Common Stock, but prior to the occurrence of the event for which such record
is taken, and the Holder exercises this Warrant, any shares of Common Stock
issuable upon exercise by reason of such adjustment shall be deemed the last
shares of Common Stock for which this Warrant is exercised (notwithstanding any
other provision to the contrary herein) and such shares or other property shall
be held in escrow for the Holder by the Issuer to be issued to the Holder upon
and to the extent that the event actually takes place, upon payment of the
current Warrant Price. Notwithstanding any other provision to the contrary
herein, if the event for which such record was taken fails to occur or is
rescinded, then such escrowed shares shall be cancelled by the Issuer and
escrowed property returned.

      5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to a national or regional
accounting firm reasonably acceptable to the Issuer and the Holder, provided
that the Issuer shall have ten (10) days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty (30) days after submission
to it of such dispute. Such opinion shall be final and binding on the parties
hereto. The costs and expenses of the initial accounting firm shall be paid
equally by the Issuer and the Holder and, in the case of an objection by the
Issuer, the costs and expenses of the subsequent accounting firm shall be paid
in full by the Issuer.

                                      -12-
<PAGE>

      6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with any exercise hereof, but in lieu of such fractional shares,
the Issuer shall round the number of shares to be issued upon exercise up to the
nearest whole number of shares.

      7. Ownership Cap and Exercise Restriction. Notwithstanding anything to the
contrary set forth in this Warrant, at no time may a Holder of this Warrant
exercise this Warrant if the number of shares of Common Stock to be issued
pursuant to such exercise would exceed, when aggregated with all other shares of
Common Stock owned by such Holder at such time, the number of shares of Common
Stock which would result in such Holder beneficially owning (as determined in
accordance with Section 13(d) of the Exchange Act and the rules thereunder) in
excess of 9.9% of the then issued and outstanding shares of Common Stock;
provided, however, that upon a holder of this Warrant providing the Issuer with
sixty-one (61) days notice (pursuant to Section 13 hereof) (the "Waiver Notice")
that such Holder would like to waive this Section 7 with regard to any or all
shares of Common Stock issuable upon exercise of this Warrant, this Section 7
will be of no force or effect with regard to all or a portion of the Warrant
referenced in the Waiver Notice; provided, further, that this provision shall be
of no further force or effect during the sixty-one (61) days immediately
preceding the expiration of the term of this Warrant.

      8. Issuer's Redemption Option. If (A) the Per Share Market Value of the
Common Stock for any twenty (20) consecutive Trading Days equals or exceeds
$5.00 per share (as may be adjusted for any stock splits or combinations of the
Common Stock) and (B) the trading volume of the Common Stock for each Trading
Day of such twenty (20) Trading Day period equals or exceeds 50,000 shares of
Common Stock, the Issuer may, at any time thereafter upon twenty (20) Trading
Days prior written notice (the "Issuer Redemption Notice") to the Holder, redeem
the unexercised portion of this Warrant in cash at a price equal to the number
of shares of Warrant Stock with respect to the unexercised portion of this
Warrant multiplied by $0.0001 (the "Issuer Redemption Price"); provided, that,
in connection with any redemption by the Issuer under this Section 8, (A) the
registration statement (the `Registration Statement") filed by the Issuer with
the Securities and Exchange Commission providing for the resale of the Warrant
Stock and the shares of Common Stock issuable upon conversion of the Series A
Convertible Preferred Stock issued pursuant to the Purchase Agreement is then in
effect and has been effective, without lapse or suspension of any kind, for a
period of sixty (60) consecutive calendar days, (B) trading in the Common Stock
shall not have been suspended by the Securities and Exchange Commission or the
OTC Bulletin Board (or other exchange or market on which the Common Stock is
trading), (C) the Issuer is in material compliance with the terms and conditions
of this Warrant and the other Transaction Documents (as defined in the Purchase

                                      -13-
<PAGE>

Agreement) and (D) the Issuer is not in possession of any material non-public
information; provided, further, that the Registration Statement is in effect
from the date of delivery of the Issuer Redemption Notice until the date which
is the later of (1) the date the Holder exercises the Warrant pursuant to the
Issuer Redemption Notice and (2) the twentieth (20th) Trading Day after the
Holder receives the Issuer Redemption Notice (the "Early Termination Date"). The
rights and privileges granted pursuant to this Warrant with respect to the
shares of Warrant Stock subject to the Issuer Redemption Notice (the "Redeemed
Warrant Shares") shall expire on the Early Termination Date if this Warrant is
not exercised with respect to such Redeemed Warrant Shares prior to such Early
Termination Date. The Issuer's Redemption Notice shall state the date of
redemption which date shall be the twenty-first (21st) Trading Day after the
Issuer has delivered the Issuer's Redemption Notice (the "Issuer's Redemption
Date"), the Issuer's Redemption Price and the number of shares to be redeemed by
the Issuer. The Issuer shall not send a Issuer's Redemption Notice unless it has
good and clear funds for a minimum of the amount it intends to redeem in a bank
account controlled by the Issuer. The Issuer shall deliver the Issuer's
Redemption Price to the Holder on the Issuer's Redemption Date. Not later than
five (5) days after receipt of the Issuer Redemption Price, Holder shall return
to the Issuer for cancellation the original Warrant to be redeemed. If the
Issuer fails to pay the Issuer's Redemption Price by the Issuer's Redemption
Date, the redemption will be declared null and void. Notwithstanding anything in
the foregoing to the contrary, if the Holder may not exercise this Warrant as a
result of the restriction contained in Section 7 hereof, the Issuer Redemption
Notice shall be deemed null and void and shall not be deemed effective until the
date that the Holder may exercise this Warrant in accordance with Section 7
hereof.

Date of Issuance: October 13, 2006

      FOR VALUE RECEIVED, the undersigned, Astrata Group Incorporated, a Nevada
corporation (together with its successors and assigns, the "Issuer"), hereby
certifies that _______________________________ or its registered assigns is
entitled to subscribe for and purchase, during the Term (as hereinafter
defined), up to ____________________________________ (_____________) shares
(subject to adjustment as hereinafter provided) of the duly authorized, validly
issued, fully paid and non-assessable Common Stock of the Issuer, at an exercise
price per share equal to the Warrant Price then in effect, subject, however, to
the provisions and upon the terms and conditions hereinafter set forth.
Capitalized terms used in this Warrant and not otherwise defined herein shall
have the respective meanings specified in Section 9 hereof.

      1. Term. The term of this Warrant shall commence on October 13, 2006 and
shall expire at 6:00 p.m., eastern time, on October 13, 2007; provided, however,
in the event that the Share Increase (as defined in the Purchase Agreement) has
not been effected within ninety (90) days following the Original Issue Date, the
term of this Warrant shall be automatically extended for a period of one (1)
year and the Issuer shall promptly issue to the Holder a new Warrant evidencing
the extension of such term (such period being the "Term").

      2. Method of Exercise; Payment; Issuance of New Warrant; Transfer and
Exchange.

                                      -1-
<PAGE>

      (a) Time of Exercise. The purchase rights represented by this Warrant may
be exercised in whole or in part during the Term at any time following the
filing of the Charter Amendment (as defined in the Purchase Agreement) in
accordance with the terms of the Purchase Agreement.

      (b) Method of Exercise. The Holder hereof may exercise this Warrant, in
whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto duly executed) at the principal office of the Issuer, and by the
payment to the Issuer of an amount of consideration therefor equal to the
Warrant Price in effect on the date of such exercise multiplied by the number of
shares of Warrant Stock with respect to which this Warrant is then being
exercised, payable at such Holder's election by certified or official bank check
or by wire transfer to an account designated by the Issuer.

      (c) Issuance of Stock Certificates. In the event of any exercise of this
Warrant in accordance with and subject to the terms and conditions hereof,
certificates for the shares of Warrant Stock so purchased shall be dated the
date of such exercise and delivered to the Holder hereof within a reasonable
time, not exceeding three (3) Trading Days after such exercise (the "Delivery
Date") or, at the request of the Holder (provided that a registration statement
under the Securities Act providing for the resale of the Warrant Stock is then
in effect or that the shares of Warrant Stock are otherwise exempt from
registration), issued and delivered to the Depository Trust Company ("DTC")
account on the Holder's behalf via the Deposit Withdrawal Agent Commission
System ("DWAC") within a reasonable time, not exceeding three (3) Trading Days
after such exercise, and the Holder hereof shall be deemed for all purposes to
be the holder of the shares of Warrant Stock so purchased as of the date of such
exercise. Notwithstanding the foregoing to the contrary, the Issuer or its
transfer agent shall only be obligated to issue and deliver the shares to the
DTC on a holder's behalf via DWAC if such exercise is in connection with a sale
or other exemption from registration by which the shares may be issued without a
restrictive legend and the Issuer and its transfer agent are participating in
DTC through the DWAC system. The Holder shall deliver this original Warrant, or
an indemnification reasonably acceptable to the Issuer undertaking with respect
to such Warrant in the case of its loss, theft or destruction, at such time that
this Warrant is fully exercised. With respect to partial exercises of this
Warrant, the Issuer shall keep written records for the Holder of the number of
shares of Warrant Stock exercised as of each date of exercise.

      (d) Compensation for Buy-In on Failure to Timely Deliver Certificates Upon
Exercise. In addition to any other rights available to the Holder, if the Issuer
fails to cause its transfer agent to transmit to the Holder a certificate or
certificates representing the Warrant Stock pursuant to an exercise on or before
the Delivery Date, and if after such date the Holder is required by its broker
to purchase (in an open market transaction or otherwise) shares of Common Stock
to deliver in satisfaction of a sale by the Holder of the Warrant Stock which
the Holder anticipated receiving upon such exercise (a "Buy-In"), then the
Issuer 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 shares of Warrant Stock that the Issuer was required to deliver to the
Holder in connection with the exercise at issue times (B) the price at which the
sell order giving rise to such purchase obligation was executed, and (2) at the
option of the Holder, either reinstate the portion of the Warrant and equivalent
number of shares of Warrant Stock 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 Issuer timely complied with its exercise and delivery obligations
hereunder. For example, if the Holder purchases Common Stock having a total
purchase price of $11,000 to cover a Buy-In with respect to an attempted
exercise of shares of Common Stock with an aggregate sale price giving rise to
such purchase obligation of $10,000, under clause (1) of the immediately
preceding sentence the Issuer shall be required to pay the Holder $1,000. The
Holder shall provide the Issuer written notice indicating the amounts payable to
the Holder in respect of the Buy-In, together with applicable confirmations and
other evidence reasonably requested by the Issuer. Nothing herein shall limit a
Holder'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 Issuer's failure to timely deliver
certificates representing shares of Common Stock upon exercise of this Warrant
as required pursuant to the terms hereof.

      (e) Transferability of Warrant. Subject to Section 2(g) hereof, this
Warrant may be transferred by a Holder, in whole or in part, without the consent
of the Issuer. If transferred pursuant to this paragraph, this Warrant may be
transferred on the books of the Issuer by the Holder hereof in person or by duly
authorized attorney, upon surrender of this Warrant at the principal office of
the Issuer, properly endorsed (by the Holder executing an assignment in the form
attached hereto) and upon payment of any necessary transfer tax or other
governmental charge imposed upon such transfer. This Warrant is exchangeable at
the principal office of the Issuer for Warrants to purchase the same aggregate
number of shares of Warrant Stock, each new Warrant to represent the right to
purchase such number of shares of Warrant Stock as the Holder hereof shall
designate at the time of such exchange. All Warrants issued on transfers or
exchanges shall be dated the Original Issue Date and shall be identical with
this Warrant except as to the number of shares of Warrant Stock issuable
pursuant thereto.

      (f) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such Holder shall fail to make any such request, the
failure shall not affect the continuing obligation of the Issuer to afford such
rights to such Holder.

      (g) Compliance with Securities Laws.

            (i) The Holder of this Warrant, by acceptance hereof, acknowledges
      that this Warrant and the shares of Warrant Stock to be issued upon
      exercise hereof are being acquired solely for the Holder's own account and
      not as a nominee for any other party, and for investment, and that the
      Holder will not offer, sell or otherwise dispose of this Warrant or any
      shares of Warrant Stock to be issued upon exercise hereof except pursuant
      to an effective registration statement, or an exemption from registration,
      under the Securities Act and any applicable state securities laws.

            (ii) Except as provided in paragraph (iii) below, this Warrant and
      all certificates representing shares of Warrant Stock issued upon exercise
      hereof shall be stamped or imprinted with a legend in substantially the
      following form:

                                      -3-

            THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE
            HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
            AMENDED (THE "SECURITIES ACT") OR ANY STATE SECURITIES LAWS AND MAY
            NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED
            UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES LAWS
            OR THE ISSUER SHALL HAVE RECEIVED AN OPINION OF COUNSEL REASONABLY
            SATISFACTORY TO THE ISSUER THAT REGISTRATION OF SUCH SECURITIES
            UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE
            STATE SECURITIES LAWS IS NOT REQUIRED.

            (iii) The Issuer agrees to reissue this Warrant or certificates
      representing any of the Warrant Stock, without the legend set forth above
      if at such time, prior to making any transfer of any such securities, the
      Holder shall give written notice to the Issuer describing the manner and
      terms of such transfer. Such proposed transfer will not be effected until:
      (a) either (i) the Issuer has received an opinion of counsel reasonably
      satisfactory to the Issuer, to the effect that the registration of such
      securities under the Securities Act is not required in connection with
      such proposed transfer, (ii) a registration statement under the Securities
      Act covering such proposed disposition has been filed by the Issuer with
      the Securities and Exchange Commission and has become effective under the
      Securities Act, (iii) the Issuer has received other evidence reasonably
      satisfactory to the Issuer that such registration and qualification under
      the Securities Act and state securities laws are not required, or (iv) the
      Holder provides the Issuer with reasonable assurances that such security
      can be sold pursuant to Rule 144 under the Securities Act; and (b) either
      (i) the Issuer has received an opinion of counsel reasonably satisfactory
      to the Issuer, to the effect that registration or qualification under the
      securities or "blue sky" laws of any state is not required in connection
      with such proposed disposition, or (ii) compliance with applicable state
      securities or "blue sky" laws has been effected or a valid exemption
      exists with respect thereto. The Issuer will respond to any such notice
      from a holder within three (3) Trading Days. In the case of any proposed
      transfer under this Section 2(h), the Issuer will use reasonable efforts
      to comply with any such applicable state securities or "blue sky" laws,
      but shall in no event be required, (x) to qualify to do business in any
      state where it is not then qualified, (y) to take any action that would
      subject it to tax or to the general service of process in any state where
      it is not then subject, or (z) to comply with state securities or "blue
      sky" laws of any state for which registration by coordination is
      unavailable to the Issuer. The restrictions on transfer contained in this
      Section 2(g) shall be in addition to, and not by way of limitation of, any
      other restrictions on transfer contained in any other section of this
      Warrant. Whenever a certificate representing the Warrant Stock is required
      to be issued to a the Holder without a legend, in lieu of delivering
      physical certificates representing the Warrant Stock, the Issuer shall
      cause its transfer agent to electronically transmit the Warrant Stock to
      the Holder by crediting the account of the Holder or Holder's Prime Broker
      with DTC through its DWAC system (to the extent not inconsistent with any
      provisions of this Warrant or the Purchase Agreement).

                                      -4-

      (h) Accredited Investor Status. In no event may the Holder exercise this
Warrant in whole or in part unless the Holder is an "accredited investor" as
defined in Regulation D under the Securities Act.

      3. Stock Fully Paid; Reservation and Listing of Shares; Covenants.

      (a) Stock Fully Paid. The Issuer represents, warrants, covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, when issued in accordance with the
terms of this Warrant, be duly authorized, validly issued, fully paid and
non-assessable and free from all taxes, liens and charges created by or through
the Issuer. The Issuer further covenants and agrees that during the period
within which this Warrant may be exercised, the Issuer will at all times have
authorized and reserved for the purpose of the issuance upon exercise of this
Warrant a number of authorized but unissued shares of Common Stock equal to at
least one hundred fifty (150%) of the number of shares of Common Stock issuable
upon exercise of this Warrant without regard to any limitations on exercise.

      (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any Governmental Authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, and maintain and increase when necessary such listing,
of, all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder (provided that such Warrant Stock has
been registered pursuant to a registration statement under the Securities Act
then in effect), and, to the extent permissible under the applicable securities
exchange rules, all unissued shares of Warrant Stock which are at any time
issuable hereunder, so long as any shares of Common Stock shall be so listed.
The Issuer will also so list on each securities exchange or market, and will
maintain such listing of, any other securities which the Holder of this Warrant
shall be entitled to receive upon the exercise of this Warrant if at the time
any securities of the same class shall be listed on such securities exchange or
market by the Issuer.

      (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Articles of Incorporation or the by-laws of the Issuer,
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other action, avoid or seek to
avoid the observance or performance of any of the terms of this Warrant, but
will at all times in good faith assist in the carrying out of all such terms and
in the taking of all such actions as may be necessary or appropriate to protect
the rights of the Holder hereof against dilution (to the extent specifically
provided herein) or impairment. Without limiting the generality of the
foregoing, the Issuer will (i) not permit the par value, if any, of its Common
Stock to exceed the then effective Warrant Price, (ii) not amend or modify any
provision of the Articles of Incorporation or by-laws of the Issuer in any
manner that would adversely affect the rights of the Holders of the Warrants,
(iii) take all such action as may be reasonably necessary in order that the
Issuer may validly and legally issue fully paid and nonassessable shares of
Common Stock, free and clear of any liens, claims, encumbrances and restrictions
(other than as provided herein) upon the exercise of this Warrant, and (iv) use
its best efforts to obtain all such authorizations, exemptions or consents from
any public regulatory body having jurisdiction thereof as may be reasonably
necessary to enable the Issuer to perform its obligations under this Warrant.

                                      -5-
<PAGE>

      (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

      (e) Payment of Taxes. The Issuer will pay any documentary stamp taxes
attributable to the initial issuance of the Warrant Stock issuable upon exercise
of this Warrant; provided, however, that the Issuer shall not be required to pay
any tax or taxes which may be payable in respect of any transfer involved in the
issuance or delivery of any certificates representing Warrant Stock in a name
other than that of the Holder in respect to which such shares are issued.

      4. Adjustment of Warrant Price. The price at which such shares of Warrant
Stock may be purchased upon exercise of this Warrant shall be subject to
adjustment from time to time as set forth in this Section 4. The Issuer shall
give the Holder notice of any event described below which requires an adjustment
pursuant to this Section 4 in accordance with the notice provisions set forth in
Section 5.

      (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale.

            (i) In case the Issuer after the Original Issue Date shall do any of
      the following (each, a "Triggering Event"): (a) consolidate or merge with
      or into any other Person and the Issuer shall not be the continuing or
      surviving corporation of such consolidation or merger, or (b) permit any
      other Person to consolidate with or merge into the Issuer and the Issuer
      shall be the continuing or surviving Person but, in connection with such
      consolidation or merger, any Capital Stock of the Issuer shall be changed
      into or exchanged for Securities of any other Person or cash or any other
      property, or (c) transfer all or substantially all of its properties or
      assets to any other Person, or (d) effect a capital reorganization or
      reclassification of its Capital Stock, then, and in the case of each such
      Triggering Event, proper provision shall be made to the Warrant Price and
      the number of shares of Warrant Stock that may be purchased upon exercise
      of this Warrant so that, upon the basis and the terms and in the manner
      provided in this Warrant, the Holder of this Warrant shall be entitled
      upon the exercise hereof at any time after the consummation of such
      Triggering Event, to the extent this Warrant is not exercised prior to
      such Triggering Event, to receive at the Warrant Price as adjusted to take
      into account the consummation of such Triggering Event, in lieu of the
      Common Stock issuable upon such exercise of this Warrant prior to such
      Triggering Event, the Securities, cash and property to which such Holder
      would have been entitled upon the consummation of such Triggering Event if
      such Holder had exercised the rights represented by this Warrant
      immediately prior thereto (including the right of a shareholder to elect
      the type of consideration it will receive upon a Triggering Event),
      subject to adjustments (subsequent to such corporate action) as nearly
      equivalent as possible to the adjustments provided for elsewhere in this
      Section 4, and the Warrant Price shall be adjusted to equal the product of

                                      -6-
<PAGE>

      (A) the closing price of the common stock of the continuing or surviving
      corporation as a result of such Triggering Event as of the date
      immediately preceding the date of the consummation of such Triggering
      Event multiplied by (B) the quotient of (i) the Warrant Price divided by
      (ii) the Per Share Market Value of the Common Stock as of the date
      immediately preceding the Original Issue Date; provided, however, the
      Holder at its option may elect to receive an amount in cash equal to the
      value of this Warrant calculated in accordance with the Black-Scholes
      formula. Immediately upon the occurrence of a Triggering Event, the Issuer
      shall notify the Holder in writing of such Triggering Event and provide
      the calculations in determining the number of shares of Warrant Stock
      issuable upon exercise of the new warrant and the adjusted Warrant Price.
      Upon the Holder's request, the continuing or surviving corporation as a
      result of such Triggering Event shall issue to the Holder a new warrant of
      like tenor evidencing the right to purchase the adjusted number of shares
      of Warrant Stock and the adjusted Warrant Price pursuant to the terms and
      provisions of this Section 4(a)(i). Notwithstanding the foregoing to the
      contrary, this Section 4(a)(i) shall only apply if the surviving entity
      pursuant to any such Triggering Event is a company that has a class of
      equity securities registered pursuant to the Securities Exchange Act of
      1934, as amended, and its common stock is listed or quoted on a national
      securities exchange, national automated quotation system or the OTC
      Bulletin Board. In the event that the surviving entity pursuant to any
      such Triggering Event is not a public company that is registered pursuant
      to the Securities Exchange Act of 1934, as amended, or its common stock is
      not listed or quoted on a national securities exchange, national automated
      quotation system or the OTC Bulletin Board, then the Holder shall have the
      right to demand that the Issuer pay to the Holder an amount in cash equal
      to the value of this Warrant calculated in accordance with the
      Black-Scholes formula.

            (ii) In the event that the Holder has elected not to exercise this
      Warrant prior to the consummation of a Triggering Event and has also
      elected not to receive an amount in cash equal to the value of this
      Warrant calculated in accordance with the Black-Scholes formula pursuant
      to the provisions of Section 4(a)(i) above, so long as the surviving
      entity pursuant to any Triggering Event is a company that has a class of
      equity securities registered pursuant to the Securities Exchange Act of
      1934, as amended, and its common stock is listed or quoted on a national
      securities exchange, national automated quotation system or the OTC
      Bulletin Board, the surviving entity and/or each Person (other than the
      Issuer) which may be required to deliver any Securities, cash or property
      upon the exercise of this Warrant as provided herein shall assume, by
      written instrument delivered to, and reasonably satisfactory to, the
      Holder of this Warrant, (A) the obligations of the Issuer under this
      Warrant (and if the Issuer shall survive the consummation of such
      Triggering Event, such assumption shall be in addition to, and shall not
      release the Issuer from, any continuing obligations of the Issuer under
      this Warrant) and (B) the obligation to deliver to such Holder such
      Securities, cash or property as, in accordance with the foregoing
      provisions of this subsection (a), such Holder shall be entitled to
      receive, and the surviving entity and/or each such Person shall have
      similarly delivered to such Holder an opinion of counsel for the surviving
      entity and/or each such Person, which counsel shall be reasonably
      satisfactory to such Holder, or in the alternative, a written
      acknowledgement executed by the President or Chief Financial Officer of
      the Issuer, stating that this Warrant shall thereafter continue in full
      force and effect and the terms hereof (including, without limitation, all
      of the provisions of this subsection (a)) shall be applicable to the
      Securities, cash or property which the surviving entity and/or each such
      Person may be required to deliver upon any exercise of this Warrant or the
      exercise of any rights pursuant hereto.

                                      -7-
<PAGE>

      (b) Stock Dividends, Subdivisions and Combinations. If at any time the
Issuer shall:

            (i) make or issue or set a record date for the holders of the Common
      Stock for the purpose of entitling them to receive a dividend payable in,
      or other distribution of, shares of Common Stock,

            (ii) subdivide its outstanding shares of Common Stock into a larger
      number of shares of Common Stock, or

            (iii) combine its outstanding shares of Common Stock into a smaller
      number of shares of Common Stock,

then (1) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the occurrence of such event would own or be entitled to
receive after the happening of such event, and (2) the Warrant Price then in
effect shall be adjusted to equal (A) the Warrant Price then in effect
multiplied by the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to the adjustment divided by (B) the number of
shares of Common Stock for which this Warrant is exercisable immediately after
such adjustment.

      (c) Certain Other Distributions. If at any time the Issuer shall make or
issue or set a record date for the holders of the Common Stock for the purpose
of entitling them to receive any dividend or other distribution of:

            (i) cash (other than a cash dividend payable out of earnings or
      earned surplus legally available for the payment of dividends under the
      laws of the jurisdiction of incorporation of the Issuer),

            (ii) any evidences of its indebtedness, any shares of stock of any
      class or any other securities or property of any nature whatsoever (other
      than cash, Common Stock Equivalents or Additional Shares of Common Stock),
      or

            (iii) any warrants or other rights to subscribe for or purchase any
      evidences of its indebtedness, any shares of stock of any class or any
      other securities or property of any nature whatsoever (other than cash,
      Common Stock Equivalents or Additional Shares of Common Stock),

                                      -8-
<PAGE>

then (1) the number of shares of Common Stock for which this Warrant is
exercisable shall be adjusted to equal the product of the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to such
adjustment multiplied by a fraction (A) the numerator of which shall be the Per
Share Market Value of Common Stock at the date of taking such record and (B) the
denominator of which shall be such Per Share Market Value minus the amount
allocable to one share of Common Stock of any such cash so distributable and of
the fair value (as determined in good faith by the Board of Directors of the
Issuer and supported by an opinion from an investment banking firm mutually
agreed upon by the Issuer and the Holder) of any and all such evidences of
indebtedness, shares of stock, other securities or property or warrants or other
subscription or purchase rights so distributable, and (2) the Warrant Price then
in effect shall be adjusted to equal (A) the Warrant Price then in effect
multiplied by the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to the adjustment divided by (B) the number of
shares of Common Stock for which this Warrant is exercisable immediately after
such adjustment. A reclassification of the Common Stock (other than a change in
par value, or from par value to no par value or from no par value to par value)
into shares of Common Stock and shares of any other class of stock shall be
deemed a distribution by the Issuer to the holders of its Common Stock of such
shares of such other class of stock within the meaning of this Section 4(c) and,
if the outstanding shares of Common Stock shall be changed into a larger or
smaller number of shares of Common Stock as a part of such reclassification,
such change shall be deemed a subdivision or combination, as the case may be, of
the outstanding shares of Common Stock within the meaning of Section 4(b).

      (d) Issuance of Additional Shares of Common Stock. In the event the Issuer
shall at any time following the Original Issuance Date issue any Additional
Shares of Common Stock (otherwise than as provided in the foregoing subsections
(b) through (c) of this Section 4), at a price per share less than the Warrant
Price then in effect or without consideration, then the Warrant Price upon each
such issuance shall be adjusted to the price equal to the consideration per
share paid for such Additional Shares of Common Stock.

      (e) Issuance of Common Stock Equivalents. In the event the Issuer shall at
any time following the Original Issuance Date take a record of the holders of
its Common Stock for the purpose of entitling them to receive a distribution of,
or shall in any manner (whether directly or by assumption in a merger in which
the Issuer is the surviving corporation) issue or sell, any Common Stock
Equivalents, whether or not the rights to exchange or convert thereunder are
immediately exercisable, and the price per share for which Common Stock is
issuable upon such conversion or exchange shall be less than the Warrant Price
in effect immediately prior to the time of such issue or sale, or if, after any
such issuance of Common Stock Equivalents, the price per share for which
Additional Shares of Common Stock may be issuable thereafter is amended or
adjusted, and such price as so amended shall be less than the Warrant Price in
effect at the time of such amendment or adjustment, then the Warrant Price then
in effect shall be adjusted as provided in Section 4(d). No further adjustments
of the number of shares of Common Stock for which this Warrant is exercisable
and the Warrant Price then in effect shall be made upon the actual issue of such
Common Stock upon conversion or exchange of such Common Stock Equivalents.

                                      -9-
<PAGE>

      (f) Other Provisions applicable to Adjustments under this Section. The
following provisions shall be applicable to the making of adjustments of the
number of shares of Common Stock for which this Warrant is exercisable and the
Warrant Price then in effect provided for in this Section 4:

            (i) Computation of Consideration. To the extent that any Additional
      Shares of Common Stock or any Common Stock Equivalents (or any warrants or
      other rights therefor) shall be issued for cash consideration, the
      consideration received by the Issuer therefor shall be the amount of the
      cash received by the Issuer therefor, or, if such Additional Shares of
      Common Stock or Common Stock Equivalents are offered by the Issuer for
      subscription, the subscription price, or, if such Additional Shares of
      Common Stock or Common Stock Equivalents are sold to underwriters or
      dealers for public offering without a subscription offering, the initial
      public offering price (in any such case subtracting any amounts paid or
      receivable for accrued interest or accrued dividends and without taking
      into account any compensation, discounts or expenses paid or incurred by
      the Issuer for and in the underwriting of, or otherwise in connection
      with, the issuance thereof). In connection with any merger or
      consolidation in which the Issuer is the surviving corporation (other than
      any consolidation or merger in which the previously outstanding shares of
      Common Stock of the Issuer shall be changed to or exchanged for the stock
      or other securities of another corporation), the amount of consideration
      therefore shall be, deemed to be the fair value, as determined reasonably
      and in good faith by the Board, of such portion of the assets and business
      of the nonsurviving corporation as the Board may determine to be
      attributable to such shares of Common Stock or Common Stock Equivalents,
      as the case may be. The consideration for any Additional Shares of Common
      Stock issuable pursuant to any warrants or other rights to subscribe for
      or purchase the same shall be the consideration received by the Issuer for
      issuing such warrants or other rights plus the additional consideration
      payable to the Issuer upon exercise of such warrants or other rights. The
      consideration for any Additional Shares of Common Stock issuable pursuant
      to the terms of any Common Stock Equivalents shall be the consideration
      received by the Issuer for issuing warrants or other rights to subscribe
      for or purchase such Common Stock Equivalents, plus the consideration paid
      or payable to the Issuer in respect of the subscription for or purchase of
      such Common Stock Equivalents, plus the additional consideration, if any,
      payable to the Issuer upon the exercise of the right of conversion or
      exchange in such Common Stock Equivalents. In the event of any
      consolidation or merger of the Issuer in which the Issuer is not the
      surviving corporation or in which the previously outstanding shares of
      Common Stock of the Issuer shall be changed into or exchanged for the
      stock or other securities of another corporation, or in the event of any
      sale of all or substantially all of the assets of the Issuer for stock or
      other securities of any corporation, the Issuer shall be deemed to have
      issued a number of shares of its Common Stock for stock or securities or
      other property of the other corporation computed on the basis of the
      actual exchange ratio on which the transaction was predicated, and for a
      consideration equal to the fair market value on the date of such
      transaction of all such stock or securities or other property of the other
      corporation. In the event any consideration received by the Issuer for any
      securities consists of property other than cash, the fair market value
      thereof at the time of issuance or as otherwise applicable shall be as
      determined in good faith by the Board. In the event Common Stock is issued
      with other shares or securities or other assets of the Issuer for
      consideration which covers both, the consideration computed as provided in
      this Section 4(f)(i) shall be allocated among such securities and assets
      as determined in good faith by the Board.

                                      -10-

            (ii) When Adjustments to Be Made. The adjustments required by this
      Section 4 shall be made whenever and as often as any specified event
      requiring an adjustment shall occur, except that any adjustment of the
      number of shares of Common Stock for which this Warrant is exercisable
      that would otherwise be required may be postponed (except in the case of a
      subdivision or combination of shares of the Common Stock, as provided for
      in Section 4(b)) up to, but not beyond the date of exercise if such
      adjustment either by itself or with other adjustments not previously made
      adds or subtracts less than one percent (1%) of the shares of Common Stock
      for which this Warrant is exercisable immediately prior to the making of
      such adjustment. Any adjustment representing a change of less than such
      minimum amount (except as aforesaid) which is postponed shall be carried
      forward and made as soon as such adjustment, together with other
      adjustments required by this Section 4 and not previously made, would
      result in a minimum adjustment or on the date of exercise. For the purpose
      of any adjustment, any specified event shall be deemed to have occurred at
      the close of business on the date of its occurrence.

            (iii) Fractional Interests. In computing adjustments under this
      Section 4, fractional interests in Common Stock shall be taken into
      account to the nearest one one-hundredth (1/100th) of a share.

            (iv) When Adjustment Not Required. If the Issuer shall take a record
      of the holders of its Common Stock for the purpose of entitling them to
      receive a dividend or distribution or subscription or purchase rights and
      shall, thereafter and before the distribution to stockholders thereof,
      legally abandon its plan to pay or deliver such dividend, distribution,
      subscription or purchase rights, then thereafter no adjustment shall be
      required by reason of the taking of such record and any such adjustment
      previously made in respect thereof shall be rescinded and annulled.

      (g) Form of Warrant after Adjustments. The form of this Warrant need not
be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

      (h) Escrow of Warrant Stock. If after any property becomes distributable
pursuant to this Section 4 by reason of the taking of any record of the holders
of Common Stock, but prior to the occurrence of the event for which such record
is taken, and the Holder exercises this Warrant, any shares of Common Stock

      5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to a national or regional
accounting firm reasonably acceptable to the Issuer and the Holder, provided
that the Issuer shall have ten (10) days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty (30) days after submission
to it of such dispute. Such opinion shall be final and binding on the parties

Issuer, the costs and expenses of the subsequent accounting firm shall be paid
in full by the Issuer.

in connection with any exercise hereof, but in lieu of such fractional shares,
the Issuer shall round the number of shares to be issued upon exercise up to the
nearest whole number of shares.

      7. Ownership Cap and Exercise Restriction. Notwithstanding anything to the
contrary set forth in this Warrant, at no time may a Holder of this Warrant
exercise this Warrant if the number of shares of Common Stock to be issued
pursuant to such exercise would exceed, when aggregated with all other shares of
Common Stock owned by such Holder at such time, the number of shares of Common
Stock which would result in such Holder beneficially owning (as determined in
accordance with Section 13(d) of the Exchange Act and the rules thereunder) in
excess of 9.9% of the then issued and outstanding shares of Common Stock;
provided, however, that upon a holder of this Warrant providing the Issuer with
sixty-one (61) days notice (pursuant to Section 13 hereof) (the "Waiver Notice")
that such Holder would like to waive this Section 7 with regard to any or all
shares of Common Stock issuable upon exercise of this Warrant, this Section 7
will be of no force or effect with regard to all or a portion of the Warrant
referenced in the Waiver Notice; provided, further, that this provision shall be
of no further force or effect during the sixty-one (61) days immediately
preceding the expiration of the term of this Warrant.
