            VOID AFTER 5:00 P.M., NEW YORK CITY TIME, ON THE
            FIFTH ANNIVERSARY OF ISSUANCE

            THIS WARRANT AND THE SHARES ISSUABLE UPON EXERCISE OF THIS WARRANT
            HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
            AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY STATE
            OF THE UNITED STATES OR ANY OTHER JURISDICTION. THE SECURITIES
            REPRESENTED HEREBY MAY NOT BE OFFERED OR SOLD IN THE ABSENCE OF AN
            EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER APPLICABLE
            SECURITIES LAWS UNLESS OFFERED, SOLD OR TRANSFERRED PURSUANT TO AN
            AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE
            LAWS.

                                         Right to Purchase 210,526 Shares of
                                         Common Stock, par value $.001 per share

Date:       December 6, 2000

                                 CELLPOINT INC.
                             STOCK PURCHASE WARRANT

      THIS CERTIFIES THAT, for value received, CASTLE CREEK TECHNOLOGY PARTNERS,
LLC, or its registered assigns, is entitled to purchase from CELLPOINT INC., a
corporation organized under the laws of the State of Nevada (the "COMPANY"), at
any time or from time to time during the period specified in Section 2 hereof,
Two Hundred Ten Thousand Five Hundred Twenty-Six (210,526) fully paid and
nonassessable shares of the Company's common stock, par value $.001 per share
(the "COMMON STOCK"), at an exercise price per share (the "EXERCISE PRICE") of
$11.40. The number of shares of Common Stock purchasable hereunder (the "WARRANT
SHARES") and the Exercise Price are subject to adjustment as provided in Section
4 hereof. The term "WARRANTS" means this Warrant and the other Initial Warrants
of the Company issued pursuant to the Securities Purchase Agreement dated
December 6, 2000 by and among the Company and the other signatories thereto (the
"SECURITIES PURCHASE AGREEMENT") and the Prepayment Warrants, if any, as defined
in and issued in accordance with the Notes, as defined in the Securities
Purchase Agreement. All references herein to monetary denominations shall refer
to lawful money of the United States of America.

      This Warrant is subject to the following terms, provisions and conditions:

      1. MANNER OF EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES.
Subject to the provisions hereof, including, without limitation, the
limitations contained in Section 7 hereof,
<PAGE>

this Warrant may be exercised by the holder hereof, in whole or in part, by the
surrender of this Warrant, together with a completed exercise agreement in the
form attached hereto (the "EXERCISE AGREEMENT"), to the Company by 5:59 p.m. New
York time on any business day at the Company's principal executive offices (or
such other office or agency of the Company as it may designate by notice to the
holder hereof) and upon (i) payment to the Company in cash, by certified or
official bank check or by wire transfer for the account of the Company, of the
Exercise Price for the Warrant Shares specified in the Exercise Agreement or
(ii) upon delivery to the Company of a written notice of an election to effect a
Cashless Exercise (as defined in Section 11(c) below) pursuant to Section 11(c)
hereof for the Warrant Shares specified in the Exercise Agreement. The Warrant
Shares so purchased shall be deemed to be issued to the holder hereof or such
holder's designee, as the record owner of such shares, as of the close of
business on the date on which this Warrant shall have been surrendered and the
completed Exercise Agreement shall have been delivered and payment shall have
been made for such shares as set forth above or, if such day is not a business
day, on the next succeeding business day. The Warrant Shares so purchased,
representing the aggregate number of shares specified in the Exercise Agreement,
shall be delivered to the holder hereof within three business days, after this
Warrant shall have been so exercised (the "DELIVERY PERIOD"). If the Company's
transfer agent is participating in the Depository Trust Company ("DTC") Fast
Automated Securities Transfer program, and so long as the certificates therefor
do not bear a legend and the holder is not obligated to return such certificate
for the placement of a legend thereon and the holder has provided the Company
with information required by DTC relating to the DTC Account of the holder or
the holder's nominee, the Company shall cause its transfer agent to
electronically transmit the Warrant Shares so purchased to the holder by
crediting the account of the holder or its nominee with DTC through its Deposit
Withdrawal Agent Commission system ("DTC TRANSFER"). If the aforementioned
conditions to a DTC Transfer are not satisfied, the Company shall deliver to the
holder physical certificates representing the Warrant Shares so purchased.
Further, the holder may instruct the Company in writing to deliver to the holder
physical certificates representing the Warrant Shares so purchased in lieu of
delivering such shares by way of DTC Transfer. Any certificates so delivered
shall be in such denominations as may be requested by the holder hereof, shall
be registered in the name of such holder or such other name as shall be
designated by such holder. Prior to the earlier of the date that the Warrant
Shares may be sold pursuant to Rule 144(k) promulgated under the Securities Act
(or a successor rule) or the date of the registration of the Warrant Shares
pursuant to that certain Registration Rights Agreement, dated as of the date
hereof, by and between the Company and the other signatories thereto (the
"REGISTRATION RIGHTS AGREEMENT") , the certificates evidencing the Warrant
Shares shall bear the restrictive legend required by the Securities Act.. After
the earlier of the dates referred to in the preceding sentence, the certificates
evidencing the Warrant Shares shall not bear any restrictive legend. If this
Warrant shall have been exercised only in part, then the Company shall at the
time of delivery of such certificates, deliver to the holder a new Warrant
representing the number of shares with respect to which this Warrant shall not
then have been exercised.

            If, at any time, a holder of this Warrant submits this Warrant, an
Exercise Agreement and payment to the Company of the Exercise Price for each of
the Warrant Shares specified in the Exercise Agreement, and the Company fails
for any reason to deliver, on or prior



                                      -2-
<PAGE>

to the fifth business day following the expiration of the Delivery Period for
such exercise, the number of shares of Common Stock to which the holder is
entitled upon such exercise (an "EXERCISE DEFAULT"), then the Company shall pay
to the holder payments ("EXERCISE DEFAULT PAYMENTS") for an Exercise Default in
the amount of (a) (N/365), multiplied by (b) the amount by which the Market
Price (as defined in Section 4(l) below) on the date the Exercise Agreement
giving rise to the Exercise Default is transmitted in accordance with this
Section 1 (the "EXERCISE DEFAULT Date") exceeds the Exercise Price in respect of
such Warrant Shares, multiplied by (c) the number of shares of Common Stock the
Company failed to so deliver in such Exercise Default, multiplied by (d) .24,
where N = the number of days from the Exercise Default Date to the date that the
Company effects the full exercise of this Warrant which gave rise to the
Exercise Default. The accrued Exercise Default Payment for each calendar month
shall be paid in cash not later than the fifth day of the month following the
month in which it has accrued.

            Nothing herein shall limit the holder's right to pursue actual
damages (but not consequential damages) for the Company's failure to comply with
the terms of this Warrant.

      2.    PERIOD OF EXERCISE.  This Warrant is immediately exercisable,
at any time or from time to time on or after the date hereof and before
5:59 p.m., New York City time, on December 5, 2005 (the "EXERCISE PERIOD").

      3.    CERTAIN AGREEMENTS OF THE COMPANY.  The Company hereby
covenants and agrees as follows:

            (a) SHARES TO BE FULLY PAID. All Warrant Shares will, upon issuance
in accordance with the terms of this Warrant, be validly issued, fully paid, and
nonassessable and free from all taxes, liens, claims and encumbrances.

            (b) RESERVATION OF SHARES. During the Exercise Period, the Company
shall at all times have authorized, and reserved for the purpose of issuance
upon exercise of this Warrant, a sufficient number of shares of Common Stock to
provide for the exercise in full of this Warrant (without giving effect to the
limitations on exercise set forth in Section 7(g) hereof).

            (c) LISTING. The Company shall promptly secure the listing of the
shares of Common Stock issuable upon exercise of this Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed or become listed (subject to official notice of
issuance upon exercise of this Warrant) and shall maintain, so long as any other
shares of Common Stock shall be so listed, such listing of all shares of Common
Stock from time to time issuable upon the exercise of this Warrant; and the
Company shall so list on each national securities exchange or automated
quotation system, as the case may be, and shall maintain such listing of, any
other shares of capital stock of the Company issuable upon the exercise of this
Warrant if and so long as any shares of the same class shall be listed on such
national securities exchange or automated quotation system.



                                      -3-
<PAGE>

            (d) CERTAIN ACTIONS PROHIBITED. The Company will not, by amendment
of its charter or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the economic benefit inuring to the holder hereof
and the exercise privilege of the holder of this Warrant against dilution or
other impairment, consistent with the tenor and purpose of this Warrant. Without
limiting the generality of the foregoing, the Company (i) will not increase the
par value of any shares of Common Stock receivable upon the exercise of this
Warrant above the lowest Exercise Price then in effect, and (ii) will take all
such actions as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and nonassessable shares of Common Stock
upon the exercise of this Warrant.

            (e) SUCCESSORS AND ASSIGNS. This Warrant will be binding upon any
entity succeeding to the Company by merger, consolidation, or acquisition of all
or substantially all of the Company's assets.

            (f) BLUE SKY LAWS. The Company shall, on or before the date of
issuance of any Warrant Shares, take such actions as the Company shall
reasonably determine are necessary to qualify the Warrant Shares for, or obtain
exemption for the Warrant Shares for, sale to the holder of this Warrant upon
the exercise hereof under applicable securities or "blue sky" laws of the states
of the United States, and shall provide evidence of any such action so taken to
the holder of this Warrant prior to such date; PROVIDED, HOWEVER, that the
Company shall not be required in connection therewith or as a condition thereto
to (a) qualify to do business in any jurisdiction where it would not otherwise
be required to qualify but for this Section 3(f), (b) subject itself to general
taxation in any such jurisdiction, (c) file a general consent to service of
process in any such jurisdiction, (d) provide any undertakings that cause the
Company undue expense or burden, or (e) make any change in its charter or
bylaws, which in each case the Board of Directors of the Company determines to
be contrary to the best interests of the Company and its stockholders.

      4.    ANTIDILUTION PROVISIONS.  During the Exercise Period, the
Exercise Price and the number of Warrant Shares issuable hereunder shall
be subject to adjustment from time to time as provided in this Section 4.

            In the event that any adjustment of the Exercise Price(s) as
required herein results in a fraction of a cent, such Exercise Price(s) shall be
rounded up or down to the nearest cent.

            (a) ADJUSTMENT OF EXERCISE PRICE(S). Except as otherwise provided in
Sections 4(c) and 4(e) hereof, if and whenever during the Exercise Period the
Company issues or sells, or in accordance with Section 4(b) hereof is deemed to
have issued or sold, any shares of Common Stock for no consideration or for a
consideration per share that is less than either the Market Price on the
Measurement Date (as such terms are hereinafter defined) or the Exercise Price
on the Measurement Date (a "DILUTIVE ISSUANCE"), then effective immediately upon
the



                                      -4-
<PAGE>

Dilutive Issuance, the Exercise Price(s) will be adjusted in accordance with the
following formula:

            E'   =   E    x           O + P/M
                                ---------------------
                                       CSDO

            where:

            E'    =     the adjusted Exercise Price;
            E     =     the Exercise Price on the Measurement Date;
            M     =     the greater of the Market Price on the Measurement
                        Date or the Exercise Price on the Measurement Date;
            O     =     the number of shares of Common Stock outstanding
                        immediately prior to the Dilutive Issuance;
            P     =     the aggregate consideration, calculated as set
                        forth in Section 4(b) hereof, received by the
                        Company upon such Dilutive Issuance; and
            CSDO  =     the total number of shares of Common Stock Deemed
                        Outstanding (as defined in Section 4(l)(i) below)
                        immediately after the Dilutive Issuance.

Notwithstanding the foregoing, no adjustment shall be made pursuant to this
Section 4(a) if such adjustment would result in an increase in the Exercise
Price.

            (b)   EFFECT ON EXERCISE PRICE(S) OF CERTAIN EVENTS.  For
purposes of determining the adjusted Exercise Price(s) under Section 4(a)
hereof, the following will be applicable:

                  (i) ISSUANCE OF RIGHTS OR OPTIONS. If the Company in any
manner issues or grants any warrants, rights or options, whether or not
immediately exercisable, to subscribe for or to purchase Common Stock or other
securities exercisable, convertible into or exchangeable for Common Stock
("CONVERTIBLE SECURITIES") (such warrants, rights and options to purchase Common
Stock or Convertible Securities are hereinafter referred to as "OPTIONS") and
the price per share for which Common Stock is issuable upon the exercise of such
Options is less than the Market Price in effect on the Measurement Date ("BELOW
MARKET OPTIONS"), then the maximum total number of shares of Common Stock
issuable upon the exercise of all such Below



                                      -5-
<PAGE>

Market Options (assuming full exercise, conversion or exchange of Convertible
Securities, if applicable) will, as of the date of the issuance or grant of such
Below Market Options, be deemed to be outstanding and to have been issued and
sold by the Company for such price per share. For purposes of the preceding
sentence, the "price per share for which Common Stock is issuable upon the
exercise of such Below Market Options" is determined by dividing (i) the total
amount, if any, received or receivable by the Company as consideration for the
issuance or granting of all such Below Market Options, plus the minimum
aggregate amount of additional consideration, if any, payable to the Company
upon the exercise of all such Below Market Options, plus, in the case of
Convertible Securities issuable upon the exercise of such Below Market Options,
the minimum aggregate amount of additional consideration payable upon the
exercise, conversion or exchange thereof at the time such Convertible Securities
first become exercisable, convertible or exchangeable, by (ii) the maximum total
number of shares of Common Stock issuable upon the exercise of all such Below
Market Options (assuming full conversion of Convertible Securities, if
applicable). No further adjustment to the Exercise Price(s) will be made upon
the actual issuance of such Common Stock upon the exercise of such Below Market
Options or upon the exercise, conversion or exchange of Convertible Securities
issuable upon exercise of such Below Market Options. If, in any case, the total
number of shares of Common Stock issuable upon exercise of any Below Market
Options or upon exercise, conversion or exchange of any Convertible Securities
is not, in fact, issued and the rights to exercise such option or to exercise,
convert or exchange such Convertible Securities shall have expired or
terminated, the Exercise Price then in effect will be readjusted to the Exercise
Price which would have been in effect at the time of such expiration or
termination had such Below Market Options or Convertible Securities, to the
extent outstanding immediately prior to such expiration or termination (other
than in respect of the actual number of shares of Common Stock issued upon
exercise or conversion thereof), never been issued.

                  (ii)  ISSUANCE OF CONVERTIBLE SECURITIES.

                        (A)   If the Company in any manner issues or sells
any Convertible Securities, whether or not immediately convertible (other than
where the same are issuable upon the exercise of Options) and the price per
share for which Common Stock is issuable upon such exercise, conversion or
exchange (as determined pursuant to Section 4(b)(ii)(B) if applicable) is less
than the Market Price in effect on the Measurement Date, then the maximum total
number of shares of Common Stock issuable upon the exercise, conversion or
exchange of all such Convertible Securities will, as of the date of the issuance
of such Convertible Securities, be deemed to be outstanding and to have been
issued and sold by the Company for such price per share. For the purposes of the
preceding sentence, the "price per share for which Common Stock is issuable upon
such exercise, conversion or exchange" is determined by dividing (i) the total
amount, if any, received or receivable by the Company as consideration for the
issuance or sale of all such Convertible Securities (taking into account the
value of any warrants or other securities issued to the purchasers of such
Convertible Securities), plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the exercise, conversion or
exchange thereof at the time such Convertible Securities first become
exercisable, convertible or exchangeable, by (ii) the maximum total number of
shares of Common Stock issuable upon the exercise, conversion or exchange of all
such Convertible Securities. No further adjustment to the Exercise Price(s) will
be made upon the actual issuance of such Common Stock upon exercise, conversion
or exchange of such Convertible Securities.

                        (B)   If the Company in any manner issues or sells
any Convertible Securities with a fluctuating conversion or exercise price or
exchange ratio (a "VARIABLE RATE CONVERTIBLE SECURITY"), then the "price per
share for which Common Stock is issuable upon such exercise, conversion or
exchange" for purposes of the calculation contemplated by Section 4(b)(ii)(A)
shall be deemed to be the price per share which would be applicable (assuming
all holding period and other conditions to any discounts contained in such




                                      -6-
<PAGE>

Convertible Security have been satisfied) if the Market Price on the Measurement
Date is assumed for purposes of this calculation to be 80% of the Market Price
on such date (the "ASSUMED VARIABLE MARKET PRICE"). Further, if the Market Price
at any time or times thereafter is less than or equal to the Assumed Variable
Market Price last used for making any adjustment under this Section 4 with
respect to any Variable Rate Convertible Security, the Exercise Price(s) in
effect at such time shall be readjusted to equal the Exercise Price(s) which
would have resulted if the Assumed Variable Market Price at the time of issuance
of the Variable Rate Convertible Security had been 80% of the Market Price
existing at the time of the adjustment required by this sentence.

                  (iii) CHANGE IN OPTION PRICE OR CONVERSION RATE. If there is a
change at any time in (i) the amount of additional consideration payable to the
Company upon the exercise of any Options; (ii) the amount of additional
consideration, if any, payable to the Company upon the exercise, conversion or
exchange of any Convertible Securities; or (iii) the rate at which any
Convertible Securities are convertible into or exchangeable for Common Stock (in
each such case, other than under or by reason of provisions designed to protect
against dilution), the Exercise Price(s) in effect at the time of such change
will be readjusted to the Exercise Price(s) which would have been in effect at
such time had such Options or Convertible Securities still outstanding provided
for such changed additional consideration or changed conversion rate, as the
case may be, at the time initially granted, issued or sold.

                  (iv) CALCULATION OF CONSIDERATION RECEIVED. If any Common
Stock, Options or Convertible Securities are issued, granted or sold for cash,
the consideration received therefor for purposes of this Warrant will be the
amount received by the Company therefor, before deduction of reasonable
commissions, underwriting discounts or allowances or other reasonable expenses
paid or incurred by the Company in connection with such issuance, grant or sale.
In case any Common Stock, Options or Convertible Securities are issued or sold
for a consideration part or all of which shall be other than cash, including, in
the case of a strategic or similar arrangement in which the other entity will
provide services to the Company, purchase services from the Company or otherwise
provide intangible consideration to the Company, the amount of the consideration
other than cash received by the Company (including the net present value of the
contribution expected by the Company for the provided or purchased services)
will be the fair market value of such consideration, except where such
consideration consists of securities, in which case the amount of consideration
received by the Company will be the Market Price thereof as of the date of
receipt. In case any Common Stock, Options or Convertible Securities are issued
in connection with any merger or consolidation in which the Company is the
surviving corporation, the amount of consideration therefor will be deemed to be
the fair market value of such portion of the net assets and business of the
non-surviving corporation as is attributable to such Common Stock, Options or
Convertible Securities, as the case may be. The Company shall calculate, using
standard commercial valuation methods appropriate for valuing such assets, the
fair market value of any consideration other than cash or securities; PROVIDED,
HOWEVER, that if the holder hereof does not agree to such fair market value
calculation within three business days after receipt thereof from the Company,
then such fair market value will be determined in good faith by an investment
banker or other appropriate



                                      -7-
<PAGE>

expert of national reputation selected by the Company and reasonably acceptable
to the holder hereof, with the costs of such appraisal to be borne by the
Company.

                  (v) EXCEPTIONS TO ADJUSTMENT OF EXERCISE PRICE(S). No
adjustment to the Exercise Price will be made (i) upon the exercise of any
warrants, options or convertible securities issued and outstanding on the date
of issuance of this Warrant and set forth on Schedule 3(d) of the Securities
Purchase Agreement in accordance with the terms of such securities as of such
date; (ii) upon the grant or exercise of any stock or options which may
hereafter be granted or exercised under any employee benefit plan of the Company
now existing or to be implemented in the future, so long as the issuance of such
stock, warrants or options is approved in accordance with the terms of such
employee benefit plan; (iii) upon the issuance of any Notes and Warrants in
accordance with the terms of the Securities Purchase Agreement; (iv) upon the
issuance of the Prepayment Warrants in accordance with the terms of the Notes;
(v) upon conversion of the Notes or exercise of the Warrants; or (vi) upon the
issuance of Common Stock in an underwritten public offering; or (vii) upon the
issuance of securities to a strategic investor (the "STRATEGIC Investor"),
provided that, in the case of clause (vii), such sale satisfies the following
conditions: (A) the sale of such securities was approved by the non-employee
members of the Board of Directors of the Company and, in the good faith
reasonable business judgment of the non-employee members of the Board of
Directors of the Company, such sale of the Company's securities to the Strategic
Investor will further the operational business interests of the Company; and (B)
the primary purpose of such sale is other than a financing arrangement.

            (c) SUBDIVISION OR COMBINATION OF COMMON STOCK. If the Company, at
any time during the Exercise Period, subdivides (by any stock split, stock
dividend, recapitalization, reorganization, reclassification or otherwise) its
shares of Common Stock into a greater number of shares, then, after the date of
record for effecting such subdivision, the Exercise Price(s) in effect
immediately prior to such subdivision will be proportionately reduced. If the
Company, at any time during the Exercise Period, combines (by reverse stock
split, recapitalization, reorganization, reclassification or otherwise) its
shares of Common Stock into a smaller number of shares, then, after the date of
record for effecting such combination, the Exercise Price(s) in effect
immediately prior to such combination will be proportionately increased.

            (d) ADJUSTMENT IN NUMBER OF SHARES. Upon each adjustment of the
Exercise Price(s) pursuant to the provisions of Section 4(c), the number of
shares of Common Stock issuable upon exercise of this Warrant at each such
Exercise Price shall be adjusted by multiplying a number equal to the Exercise
Price in effect immediately prior to such adjustment by the number of shares of
Common Stock issuable upon exercise of this Warrant at such Exercise Price
immediately prior to such adjustment and dividing the product so obtained by the
adjusted Exercise Price.

            (e) CONSOLIDATION, MERGER OR SALE. In case of any consolidation of
the Company with, or merger of the Company into, any other corporation, or in
case of any sale or conveyance of all or substantially all of the assets of the
Company other than in connection with a plan of complete liquidation of the
Company at any time during the Exercise Period, then as a condition of such
consolidation, merger or sale or conveyance, adequate provision will be made




                                      -8-
<PAGE>

whereby the holder of this Warrant will have the right to acquire and receive
upon exercise of this Warrant in lieu of the shares of Common Stock immediately
theretofore acquirable upon the exercise of this Warrant, such shares of stock,
securities, cash or assets as may be issued or payable with respect to or in
exchange for the number of shares of Common Stock immediately theretofore
acquirable and receivable upon exercise of this Warrant had such consolidation,
merger or sale or conveyance not taken place. In any such case, the Company will
make appropriate provision to insure that the provisions of this Section 4
hereof will thereafter be applicable as nearly as may be in relation to any
shares of stock or securities thereafter deliverable upon the exercise of this
Warrant. The Company will not effect any consolidation, merger or sale or
conveyance unless prior to the consummation thereof, the successor corporation
(if other than the Company) assumes by written instrument the obligations under
this Warrant and the obligations to deliver to the holder of this Warrant such
shares of stock, securities or assets as, in accordance with the foregoing
provisions, the holder may be entitled to acquire.


            (f) DISTRIBUTION OF ASSETS. In case the Company shall declare or
make any distribution of its assets (or rights to acquire its assets) to holders
of Common Stock as a partial liquidating dividend, stock repurchase, by way of
return of capital or otherwise (including any dividend or distribution to the
Company's stockholders of cash or shares (or rights to acquire shares) of
capital stock of a subsidiary) (a "DISTRIBUTION"), at any time during the
Exercise Period, then the holder of this Warrant shall be entitled upon exercise
of this Warrant for the purchase of any or all of the shares of Common Stock
subject hereto, to receive the amount of such assets (or rights) which would
have been payable to the holder had such holder been the holder of such shares
of Common Stock on the record date for the determination of stockholders
entitled to such Distribution. If the Company distributes rights, warrants,
options or any other form of convertible securities and the right to exercise or
convert such securities would expire in accordance with its terms prior to the
exercise of the Warrants, then the terms of such securities shall provide that
such exercise or convertibility right shall remain in effect until 30 days after
the date the holders of the Warrants receive such securities pursuant to the
exercise hereof.

            (g) NOTICE OF ADJUSTMENT. Upon the occurrence of any event which
requires any adjustment of the Exercise Price(s), then, and in each such case,
the Company shall give notice thereof to the holder of this Warrant, which
notice shall state the Exercise Price(s) resulting from such adjustment and the
increase or decrease in the number of Warrant Shares purchasable at each such
price upon exercise, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based. Such calculation
shall be certified by the chief financial officer of the Company.

            (h) MINIMUM ADJUSTMENT OF EXERCISE PRICE. No adjustment of the
Exercise Price shall be made in an amount of less than $.01, but any such lesser
adjustment shall be carried forward and shall be made at the time and together
with the next subsequent adjustment which, together with any adjustments so
carried forward, shall amount to not less than $.01.

            (i) NO FRACTIONAL SHARES. No fractional shares of Common Stock are
to be issued upon the exercise of this Warrant, but the Company shall pay a cash
adjustment in respect



                                      -9-
<PAGE>

of any fractional share which would otherwise be issuable in an amount equal to
the same fraction of the Market Price of a share of Common Stock on the date of
such exercise.

            (j)   OTHER NOTICES.  In case at any time:

                  (i) the Company shall declare any dividend upon the Common
Stock payable in shares of stock of any class or make any other distribution
(other than dividends or distributions payable in cash out of retained earnings
consistent with the Company's past practices with respect to declaring dividends
and making distributions) to the holders of the Common Stock;

                  (ii) the Company shall offer for subscription pro rata to the
holders of the Common Stock any additional shares of stock of any class or other
rights;

                  (iii) there shall be any capital reorganization of the
Company, or reclassification of the Common Stock, or consolidation or merger of
the Company with or into, or sale of all or substantially all of its assets to,
another corporation or entity; or

                  (iv)  there shall be a voluntary or involuntary
dissolution, liquidation or winding-up of the Company;

then, in each such case, the Company shall give to the holder of this Warrant
(a) notice of the date or estimated date on which the books of the Company shall
close or a record shall be taken for determining the holders of Common Stock
entitled to receive any such dividend, distribution, or subscription rights or
for determining the holders of Common Stock entitled to vote in respect of any
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding-up and (b) in the case of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, notice of the date (or, if not then known, a reasonable estimate
thereof by the Company) when the same shall take place. Such notice shall also
specify the date on which the holders of Common Stock shall be entitled to
receive such dividend, distribution, or subscription rights or to exchange their
Common Stock for stock or other securities or property deliverable upon such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding-up, as the case may be. Such notice shall be given at
least 30 days prior to the record date or the date on which the Company's books
are closed in respect thereto. Failure to give any such notice or any defect
therein shall not affect the validity of the proceedings referred to in clauses
(i), (ii), (iii) and (iv) above. Notwithstanding the foregoing, the Company
shall publicly disclose the substance of any notice delivered hereunder prior to
delivery of such notice to the holder of this Warrant.

            (k) CERTAIN EVENTS. If, at any time during the Exercise Period, any
event occurs of the type contemplated by the adjustment provisions of this
Section 4 but not expressly provided for by such provisions, the Company will
give notice of such event as provided in Section 4(g) hereof, and the Company's
Board of Directors will make an appropriate adjustment in the Exercise Price(s)
and the number of shares of Common Stock acquirable upon exercise of



                                      -10-
<PAGE>

this Warrant at each such Exercise Price so that the rights of the holder shall
be neither enhanced nor diminished by such event.

            (l)   CERTAIN DEFINITIONS.

                  (i) "COMMON STOCK DEEMED OUTSTANDING" shall mean the number of
shares of Common Stock actually outstanding (not including shares of Common
Stock held in the treasury of the Company), plus (x) in the case of any
adjustment required by Section 4(a) resulting from the issuance of any Options,
the maximum total number of shares of Common Stock issuable upon the exercise of
the Options for which the adjustment is required (including any Common Stock
issuable upon the conversion of Convertible Securities issuable upon the
exercise of such Options), and (y) in the case of any adjustment required by
Section 4(a) resulting from the issuance of any Convertible Securities, the
maximum total number of shares of Common Stock issuable upon the exercise,
conversion or exchange of the Convertible Securities for which the adjustment is
required, as of the date of issuance of such Convertible Securities, if any.

                  (ii) "MARKET PRICE", as of any date, (i) means the average of
the closing bid prices for the shares of Common Stock as reported on the NASDAQ
National Market ("NASDAQ") by Bloomberg Financial Markets (or a comparable
reporting service of national reputation selected by the Corporation and
reasonably acceptable to the holder) ("BLOOMBERG") for the five consecutive
trading days immediately preceding such date, or (ii) if NASDAQ is not the
principal trading market for the shares of Common Stock, the average of the last
reported bid prices as reported by Bloomberg on the principal trading market for
the Common Stock during the same period, or, if there is no bid price for such
period, the last reported sales price as reported by Bloomberg for such period,
or (iii) if market value cannot be calculated as of such date on any of the
foregoing bases, the Market Price shall be the average fair market value as
reasonably determined by an investment banking firm selected by the Company and
reasonably acceptable to the holder, with the costs of the appraisal to be borne
by the Company. The manner of determining the Market Price of the Common Stock
set forth in the foregoing definition shall apply with respect to any other
security in respect of which a determination as to market value must be made
hereunder.

                  (iii) "COMMON STOCK", for purposes of this Section 4, includes
the Common Stock and any additional class of stock of the Company having no
preference as to dividends or distributions on liquidation, provided that the
shares purchasable pursuant to this Warrant shall include only Common Stock in
respect of which this Warrant is exercisable, or shares resulting from any
subdivision or combination of such Common Stock, or in the case of any
reorganization, reclassification, consolidation, merger, or sale of the
character referred to in Section 4(e) hereof, the stock or other securities or
property provided for in such Section.

                  (iv) "MEASUREMENT DATE" means (i) for purposes of any private
offering of securities under Section 4(2) of the Securities Act of 1933, as
amended, the date that the Company enters into legally binding definitive
agreements for the issuance and sale of such securities and (ii) for purposes of
any other issuance of securities, the date of issuance thereof.

      5.    ISSUE TAX. The issuance of certificates for Warrant Shares upon the
exercise of this Warrant shall be made without charge to the holder of this
Warrant or such shares for any issuance tax or other costs in respect thereof,
provided that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than the holder of this Warrant.

      6.    NO RIGHTS OR LIABILITIES AS A STOCKHOLDER. This Warrant shall not
entitle the holder hereof to any voting rights or other rights as a stockholder
of the Company. No provision of this Warrant, in the absence of affirmative
action by the holder hereof to purchase Warrant Shares, and no mere enumeration
herein of the rights or privileges of the holder hereof, shall give rise to any
liability of such holder for the Exercise Price or as a stockholder of the
Company, whether such liability is asserted by the Company or by creditors of
the Company.

      7.    TRANSFER, EXCHANGE AND REPLACEMENT OF WARRANT.

            (a) RESTRICTION ON TRANSFER; ALLOCATION OF CAP AMOUNT. This Warrant
and the rights granted to the holder hereof are transferable, in whole or in
part, upon surrender of this Warrant, together with a properly executed
assignment in the form attached hereto, at the office or agency of the Company
referred to in Section 7(e) below, PROVIDED, HOWEVER, that any transfer or
assignment shall be subject to the prior written consent of the Company, which
consent may not be unreasonably withheld, and to the conditions set forth in
Sections 7(f) and (g) hereof and to the provisions of Sections 2(f) and 2(g) of
the Securities Purchase Agreement. Until due presentment for registration of
transfer on the books of the Company, the Company may treat the registered
holder hereof as the owner and holder hereof for all purposes, and the Company
shall not be affected by any notice to the contrary. Notwithstanding anything to
the contrary contained herein, the registration rights described in Section 8
hereof are assignable only in accordance with the provisions of the Registration
Rights Agreement. The initial Cap Amount (as defined below) applicable to
holders of Warrants shall be allocated pro rata among the holders of the
Warrants based on the aggregate number of Warrant Shares and Conversion Shares
(as defined in the Note) issuable to each holder of Warrants. In the event a
holder shall sell or otherwise transfer any of such holder's Warrants each
transferee shall be allocated a pro rata portion of such transferor's Cap
Amount. Any portion of the Cap Amount applicable to Warrants which remains
allocated to any person or entity which does not hold any Warrants shall be
allocated to the remaining holders of Warrants, pro rata based on the
outstanding principal amount of Warrants then held by such holders.

            (b) WARRANT EXCHANGEABLE FOR DIFFERENT DENOMINATIONS. This Warrant
is exchangeable, upon the surrender hereof by the holder hereof at the office or
agency of the Company referred to in Section 7(e) below, for new Warrants of
like tenor of different denominations representing in the aggregate the right to
purchase the number of shares of Common Stock which may be purchased hereunder,
each of such new Warrants to represent the right to purchase such number of
shares (at the Exercise Price therefor) as shall be designated by the holder
hereof at the time of such surrender.



                                      -12-
<PAGE>

            (c) REPLACEMENT OF WARRANT. Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction, or mutilation of
this Warrant and, in the case of any such loss, theft, or destruction, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

            (d) CANCELLATION; PAYMENT OF EXPENSES. Upon the surrender of this
Warrant in connection with any transfer, exchange, or replacement as provided in
this Section 7, this Warrant shall be promptly canceled by the Company. The
Company shall pay all taxes (other than securities transfer taxes) and all other
expenses (other than legal expenses, if any, incurred by the Holder or
transferees) and charges payable in connection with the preparation, execution,
and delivery of Warrants pursuant to this Section 7. The Company shall indemnify
and reimburse the holder of this Warrant for all losses and damages arising as a
result of or related to any breach of the terms of this Warrant, including costs
and expenses (including reasonable legal fees) incurred by such holder in
connection with the enforcement of its rights hereunder.

            (e) WARRANT REGISTER. The Company shall maintain, at its principal
executive offices (or such other office or agency of the Company as it may
designate by notice to the holder hereof), a register for this Warrant, in which
the Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each transferee and
each prior owner of this Warrant.

            (f) EXERCISE OR TRANSFER WITHOUT REGISTRATION. If, at the time of
the surrender of this Warrant in connection with any exercise, transfer, or
exchange of this Warrant, this Warrant (or, in the case of any exercise, the
Warrant Shares issuable hereunder), shall not be registered under the Securities
Act and under applicable state securities or blue sky laws, the Company may
require, as a condition of allowing such exercise, transfer, or exchange, (i)
that the holder or transferee of this Warrant, as the case may be, furnish to
the Company a written opinion of counsel (which opinion shall be in form,
substance and scope customary for opinions of counsel in comparable
transactions) to the effect that such exercise, transfer, or exchange may be
made without registration under the Securities Act and under applicable state
securities or blue sky laws, (ii) that the holder or transferee execute and
deliver to the Company an investment letter in form and substance acceptable to
the Company and (iii) that the transferee be an "accredited investor" as defined
in Rule 501(a) promulgated under the Securities Act; PROVIDED that no such
opinion, letter, or status as an "accredited investor" shall be required in
connection with a transfer pursuant to Rule 144 under the Securities Act.

            (g)   ADDITIONAL RESTRICTION ON EXERCISE.

            (i) NO FIVE PERCENT HOLDERS. Notwithstanding anything to the
contrary contained herein, this Warrant shall not be exercisable by the holder
to the extent (but only to the extent) that, if exercisable by the holder, the
holder would be the beneficial owner of more than 4.99% of the shares of Common
Stock. For the purposes of this paragraph, beneficial ownership and all
determinations and calculations, shall be determined in accordance with Section
13(d) of



                                      -13-
<PAGE>

the Securities Exchange Act of 1934, as amended, and all applicable rules and
regulations thereunder. For clarification, it is expressly a term of this
security that the limitations contained in this Section 7(g)(i) shall apply to
each successive holder. The restriction contained in this Section 7(g)(i), may
not be altered, amended, deleted or changed in any manner whatsoever unless the
holders of a majority of the outstanding Shares of Common Stock and the holder
hereof approve such alteration, amendment, deletion or change.

            (ii) CAP AMOUNT. Notwithstanding anything to the contrary contained
herein, unless stockholder approval of the Stockholder Matters (as defined in
Section 4(k) of the Securities Purchase Agreement) has been obtained, this
Warrant shall not be exercisable to the extent that such exercise would result
in the issuance of more than Two Million One Hundred Nine Thousand Seven Hundred
Seventeen (2,109,717) shares of Common Stock (the "CAP AMOUNt") in the aggregate
pursuant to the exercise of the Warrants and the conversion of the Notes.

      8.    REGISTRATION RIGHTS. The initial holder of this Warrant (and certain
assignees thereof) is entitled to the benefit of such registration rights in
respect of the Warrant Shares as are set forth in the Registration Rights
Agreement, including the right to assign such rights to certain assignees, as
set forth therein.

      9.    NOTICES. Any notices required or permitted to be given under the
terms of this Warrant shall be delivered personally or by courier or by
confirmed telecopy, and shall be effective upon receipt or refusal of receipt,
if delivered personally or by courier, or by confirmed telecopy, in each case
addressed to a party. The addresses for such communications shall be:

      10 GOVERNING LAW; JURISDICTION. This Warrant shall be governed by and
construed in accordance with the laws of the State of New York. The Company and
the registered holder irrevocably consent to the jurisdiction of the United
States federal courts and state courts located in the State of New York in any
suit or proceeding based on or arising under this Warrant and irrevocably agree
that all claims in respect of such suit or proceeding may be determined in such
courts. The Company and the registered holder irrevocably waive any objection to
the laying of venue and the defense of an inconvenient forum to the maintenance
of such suit or proceeding. The Company and the registered holder further agree
that service of process upon it mailed by certified or registered mail shall be
deemed in every respect effective service of process upon it in any such suit or
proceeding. Nothing herein shall affect the right of the Company or the
registered holder to serve process in any other manner permitted by law. The
Company and the registered holder agree that a final non-appealable judgment in
any such suit or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on such judgment or in any other lawful manner.

      11.   MISCELLANEOUS.

            (a)   AMENDMENTS.  This Warrant and any provision hereof may
only be amended by an instrument in writing signed by the Company and the
holder hereof.

            (b)   DESCRIPTIVE HEADINGS.  The descriptive headings of the
several Sections of this Warrant are inserted for purposes of reference
only, and shall not affect the meaning or construction of any of the
provisions hereof.

            (c)   CASHLESS EXERCISE. Notwithstanding anything to the contrary
contained in this Warrant, this Warrant may be exercised at any time during the
Exercise Period by presentation and surrender of this Warrant to the Company at
its principal executive offices with a written notice of the holder's intention
to effect a cashless exercise, including a calculation of the number of shares
of Common Stock to be issued upon such exercise in accordance with the terms
hereof (a "CASHLESS Exercise"). In the event of a Cashless Exercise, in lieu of
paying the Exercise Price in cash, the holder shall surrender this Warrant for
that number of shares of Common Stock determined by multiplying the number of
Warrant Shares to which it would otherwise be entitled by a fraction, the
numerator of which shall be the difference between the Market Price per share of
the Common Stock on the date of exercise and the Exercise Price, and the
denominator of which shall be such Market Price per share of Common Stock.

            (d) TRADING DAY. For purposes of this Warrant, the term "trading
day" means any day on which NASDAQ or, if the Common Stock is not then traded on
NASDAQ, the principal United States securities exchange or trading market where
the Common Stock is then listed or traded, is open for trading.
