NEITHER THIS WARRANT NOR THE SHARES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE
STATE SECURITIES LAWS.

THIS WARRANT MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED AND THE
SHARES ISSUABLE UPON EXERCISE OF THIS WARRANT CANNOT BE SOLD OR TRANSFERRED IN
THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE WARRANT
OR STOCK UNDER SUCH ACT AND APPLICABLE LAWS OR SOME OTHER EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF SUCH ACT AND APPLICABLE LAWS OR AN OPINION OF
COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT
REQUIRED.


                                    WARRANT

       TO PURCHASE SERIES D CONVERTIBLE PREFERRED STOCK OR COMMON STOCK,
                             AS SET FORTH BELOW, OF

              WORLD COMMERCE ONLINE, INC., A DELAWARE CORPORATION

            EXPIRING AT THE END OF THE OPTION PERIOD (DEFINED BELOW)


         This Is To Certify That Interprise Technology Partners, L.P. (the
"HOLDER") or registered assigns, is entitled to purchase from World Commerce
Online, Inc., a Delaware corporation (the "COMPANY"), at any time until 5 P.M.
Eastern Time, on March 30, 2006 (the "OPTION PERIOD") but not thereafter, at an
exercise price per share as set forth below, such number of fully paid and
non-assessable shares of the Company (the shares issuable pursuant to this
warrant are referred to as "WARRANT SHARES"), as set forth below, subject to
adjustment as hereinafter provided.

         ss. 1.   Exercise of Warrant.

         (a)      Exercise by Payment. To exercise this Warrant in whole or in
part, the holder hereof shall deliver to the Company at its principal office in
Orlando, Florida, (a) a written notice, in substantially the form of the
Subscription Notice appearing at the end of this Warrant, of such holder's
election to exercise this Warrant, which notice shall specify the number of
Warrant Shares to be purchased, (b) a certified check drawn on, or official
bank check, payable to the Company in an


<PAGE>   2


amount equal to the multiple of the Exercise Price (as adjusted) and the number
of Warrant Shares being purchased, and (c) this Warrant. The Company shall as
promptly as practicable, and in any event within 20 days thereafter, execute
and deliver or cause to be executed and delivered, in accordance with such
notice, a certificate or certificates representing the aggregate number of
Warrant Shares specified in such notice. The stock certificate or certificates
so delivered shall be in the denomination of 100 shares each or such lesser or
greater denomination as may be specified in such notice and shall be issued in
the name of such holder or such other name as shall be designated in such
notice. Such certificate or certificates shall be deemed to have been issued
and such holder or any other person so designated to be named therein shall be
deemed for all purposes to have become a holder of record of such Warrant
Shares as of the date such notice is received by the Company as aforesaid. If
this Warrant shall have been exercised only in part, the Company shall, at the
time of delivery of said certificate or certificates, deliver to such holder a
new Warrant evidencing the rights of such holder to purchase the remaining
Warrant Shares called for by this Warrant, which new Warrant shall in all other
respects be identical to this Warrant, or, at the request of such holder,
appropriate notation may be made on this Warrant and the same returned to such
holder. The Company shall pay all expenses, taxes and other charges payable in
connection with the preparation, issue and delivery of such stock certificates
and new Warrants, except that, in case such stock certificates or new Warrants
shall be registered in a name or names other than the name of the holder of
this Warrant, funds sufficient to pay all stock transfer taxes that are payable
upon the issuance of such stock certificate or certificates or new Warrants
shall be paid by the holder hereof at the time of delivering the notice of
exercise mentioned above.

         (b)      Exercise on Net Issuance Basis. At any time, in lieu of
payment to the Company as set forth in Section 1(a) above, the holder hereof
may convert this Warrant, in whole or in part, into the number of Warrant
Shares determined by dividing (i) the aggregate Fair Market Value of the number
of Warrant Shares issuable upon the proposed exercise of this Warrant (on an as
converted basis) minus the aggregate Exercise Price of the number of Warrant
Shares issuable upon the proposed exercise of this Warrant by (ii) the Fair
Market Value of one Warrant Share. "FAIR MARKET VALUE" shall mean (A) during
the time the Company is registered under the Securities Exchange Act of 1934,
as amended, the average closing price of the Warrant Shares reported for the
five business days immediately before the holder hereof delivers its Notice of
Exercise to the Company, or if there have been no sales on any such business
day, the average of the highest and lowest asked prices at the end of such
business date; and (B) at all other times, the fair market value of the Warrant
Shares as determined in good faith by the Board of Directors of the Company.

         (c)      Valid Issuance. All shares of stock issued upon the exercise
of this Warrant shall be validly issued, fully paid and nonassessable and, if
the class or


                                       2
<PAGE>   3


series of Warrant Shares is then listed on a national securities exchange,
shall be duly listed thereon.

         (d)      Exercise Price.

                  (i)      If the class of Warrant Shares is Series D
Convertible Preferred Stock, par value $.001 ("SERIES D PREFERRED STOCK"), the
exercise price per Warrant Share (the "EXERCISE PRICE") shall be the lesser of:

                           (A)      $1.00 based on each share of Series D
Preferred Stock being initially convertible into one share of Common Stock, par
value $.001, subject to adjustment as set forth in this Warrant; or

                           (B)      the price per share of Series D Preferred
Stock issued in an investment of no less than $10,000,000 in Series D Preferred
Stock (an investment of no less than $10,000,000 in Series D Preferred Stock is
referred to as a "QUALIFIED SERIES D INVESTMENT"), subject to adjustment as set
forth in this Warrant.

                  (ii)     If the class of Warrant Shares is Common Stock, par
value $.001 ("COMMON STOCK"), then the Exercise Price shall be as set forth in
Section 1(e) below, subject to adjustment as set forth in this Warrant.

         (e)      Number and Class of Warrant Shares. The number and class of
shares of Warrant Shares shall be determined as follows:

                  (i)      Number, Generally. The total number of Warrant
Shares shall equal the quotient obtained by dividing $30,000 by the Exercise
Price, as adjusted pursuant to this Warrant.

                  (ii)     Determination of Number and Class of Warrant Shares.

                           (A)      In the event that the holder exercises this
Warrant after a Qualified Series D Investment, then this Warrant shall be
exercisable for Series D Preferred Stock.

                           (B)      Notwithstanding Section 1(e)(ii)(A) above,
in the event that the holder exercises this Warrant after a Qualified Series D
Investment, but all (and not less than all) of the Company's Series D Preferred
Stock has then been redeemed or converted into shares of the Company's Common
Stock in accordance with the Company's Certificate of Incorporation, then this
Warrant shall be exercisable for that number of shares of the Company's Common
Stock equal to the number of shares of the Common Stock that would have been
received if this Warrant had been exercised in full and the Series D Preferred
Stock received thereupon had been converted immediately prior to such event,
and the Exercise


                                       3
<PAGE>   4


Price shall be adjusted to equal the quotient obtained by dividing (x) the
aggregate Exercise Price of the maximum number of shares of Series D Preferred
Stock for which this Warrant was exercisable immediately prior to such
conversion or redemption, by (y) the number of shares of Common Stock for which
this Warrant is exercisable immediately after such conversion or redemption.

                           (C)      In the event that the holder exercises this
Warrant after the closing of a Qualified Common Investment (as defined below),
then this Warrant shall be exercisable for that number of shares of the
Company's Common Stock equal to the quotient obtained by dividing $30,000 by
the lesser of $1.00 or the price per share of the Common Stock issued in the
Qualified Common Investment (subject to adjustment for any stock split,
consolidation or reorganization of the Common Stock or the issuance of any
stock dividends in Common Stock, and subject to adjustment as per Section 7
below), and the Exercise Price shall be adjusted to equal the lesser of $1.00
or the price per share of the Common Stock issued in the Qualified Common
Investment (subject to adjustment for any stock split, consolidation or
reorganization of the Common Stock or the issuance of any stock dividends in
Common Stock, and subject to adjustment as per Section 7 below). For purposes
of this Warrant, the term "QUALIFIED COMMON INVESTMENT" shall mean an
underwritten public offering, pursuant to an effective registration statement
under the Securities Act of 1933 as amended, covering the offer and sale of
Common Stock for the account of the Company in which the aggregate net proceeds
to the Company equal at least $10,000,000 and that closes prior to the
consummation of a Qualified Series D Investment (each of the Qualified Series D
Investment and Qualified Common Investment investments is referred to as a
"QUALIFIED INVESTMENT").

                           (D)      In the event that the holder exercises this
Warrant and there has not been a Qualified Investment, then this Warrant shall
be exercisable for that number of shares of the Company's Common Stock equal to
the quotient obtained by dividing $30,000 by $1.00 (subject to adjustment for
any stock split, consolidation or reorganization of the Common Stock or the
issuance of any stock dividends, and subject to adjustment as per Section 7
below), and the Exercise Price shall be adjusted to $1.00.

         (f)      Special Adjustments.

                  (i)      Prior to the earlier of a Qualified Investment or
September 30, 2001, if the Company issues any warrants for warrant shares of
identical classes as the Warrant Shares in connection with a loan to the
Company (the "SUBSEQUENT WARRANTS") that provide for an exercise price per
warrant share that is lower than the Exercise Price set forth in Section 1(d)
herein, the Exercise Price will be reduced to the Exercise Price in such
Subsequent Warrants.

                  (ii)     As described in the foregoing subsections of Section
1(e), the


                                       4
<PAGE>   5


number of Warrant Shares is initially calculated from a fraction (a) the
numerator of which is the Loan Ratio (as hereinafter defined) multiplied by the
Loan Amount (as hereinafter defined) and (b) the denominator of which is the
Exercise Price. The Loan Amount is the principal amount as set forth in the
Loan Agreement by and between the Company and the holder dated as of the date
hereof. The Loan Ratio is Twenty Percent (20%) (the "LOAN RATIO"). In the event
that Subsequent Warrants provide for a Loan Ratio that is greater than Twenty
Percent (20%), the Loan Ratio herein will be increased to an amount equal to
the Loan Ratio in such Subsequent Warrants.

         (g)      Fractional Shares. The Company shall not be required upon any
exercise of this Warrant to issue a certificate representing any fraction of a
Warrant Share, but, in lieu thereof, shall pay to the holder of this Warrant
cash in an amount equal to a corresponding fraction (calculated to the nearest
1/100 of a share) of the market value of one Warrant Share as of the date of
receipt by the Company of notice of exercise of this Warrant, as determined in
good faith by the Board of Directors of the Company.

         (h)      This Warrant may be exercised, in whole or in part, in one or
more exercises.

         ss. 2.   Transfer, Division and Combination.

         The Company agrees to maintain at its principal office in Orlando,
Florida, books for the registration and transfer of the Warrants, and this
Warrant and all rights hereunder are transferable, in whole or in parts, on
such books at such office, upon surrender of this Warrant at such office,
together with a written assignment of this Warrant duly executed by the holder
hereof or his agent or attorney and funds sufficient to pay any stock transfer
taxes payable upon the making of such transfer. Upon such surrender and payment
the Company shall execute and deliver a new Warrant or Warrants in the name of
the assignee or assignees and in the denominations specified in such instrument
of assignment, and this Warrant shall promptly be canceled. If and when this
Warrant is assigned in blank, the Company may (but shall not be obliged to)
treat the bearer hereof as the absolute owner of this Warrant for all purposes
and the Company shall not be affected by any notice to the contrary. A Warrant
may be exercised by a new holder for the purchase of Warrant Shares without
having a new Warrant issued.

         This Warrant may be divided or combined with other Warrants upon
presentation hereof at such principal office in Orlando, Florida, together with
a written notice specifying the names and denominations in which new Warrants
are to be issued, signed by the holder hereof or his agent or attorney. Subject
to compliance with the preceding paragraph as to any transfer that may be
involved in such division or combination, the Company shall execute and deliver
a new


                                       5
<PAGE>   6


Warrant or Warrants in exchange for the Warrant or Warrants to be divided or
combined in accordance with such notice.

         The Company shall pay all expenses, taxes (other than stock transfer
taxes) and other charges payable in connection with the preparation, issue and
delivery of Warrants hereunder.

         ss. 3.   Certain Covenants.

         The Company covenants and agrees that:

                  (a)      it will at all times reserve and set apart and have,
         free from preemptive rights, and all liens, claims, encumbrances or
         restrictions, a number of authorized but unissued Common Stock and, if
         a Qualified Series D Investment is made, Series D Preferred Stock
         sufficient to enable it at any time to fulfill all its obligations
         hereunder;

                  (b)      before taking any action that would cause an
         adjustment reducing the Exercise Price below the then par value of the
         shares of Common Stock issuable upon exercise of the Warrants, the
         Company will take any corporate action that may be necessary in order
         that the Company may validly and legally issue fully paid and
         nonassessable shares of such Common Stock at such adjusted Exercise
         Price; and

                  (c)      it will not, by charter amendment or through
         reorganization, consolidation, merger, dissolution or sale of assets,
         or by any other voluntary act, avoid or seek to avoid the observance
         or performance of any of the covenants, stipulations or conditions to
         be observed or performed hereunder by the Company.

         ss. 4.   Notices.

         In case the Company proposes

                  (a)      to pay any dividend payable in stock (of any class
         or classes) or in Convertible Securities upon its Series D Preferred
         Stock or Common Stock or make any distribution (other than ordinary
         cash dividends) to the holders of its Series D Preferred Stock or
         Common Stock, or

                  (b)      to grant to the holders of its Series D Preferred
         Stock or Common Stock generally any rights or options, or

                  (c)      to effect any capital reorganization or
         reclassification of capital stock of the Company, or


                                       6
<PAGE>   7


                  (d)      to consolidate with, or merge into, any other
         corporation or to transfer its property as an entirety or
         substantially as an entirety, or

                  (e)      to effect the liquidation, dissolution or winding up
         of the Company,

then the Company shall cause notice of any such intended action to be given to
all holders of record of outstanding Warrants not less than 30 days before the
date on which the transfer books of the Company shall close or a record be
taken for such stock dividend, distribution or granting of rights or options,
or the date when such capital reorganization, reclassification, consolidation,
merger, transfer, liquidation, dissolution or winding up shall be effective, as
the case may be.

         Any notice or other document required or permitted to be given or
delivered to holders of record of Warrants shall be mailed first-class postage
prepaid to each such holder at the last address shown on the books of the
Company maintained for the registry and transfer of the Warrants. Any notice or
other document required or permitted to be given or delivered to holders of
record of Common Stock issued pursuant to Warrants shall be mailed first-class
postage prepaid to each such holder at such holder's address as the same
appears on the stock records of the Company. Any notice or other document
required or permitted to be given or delivered to the Company shall be mailed
first class postage prepaid to the principal office of the Company, at 9677
Tradeport Drive, Orlando, Florida 32837, or delivered to the office of one of
the Company's executive officers at such address, or such other address within
the United States of America as shall have been furnished by the Company to the
holders of record of such Warrants and the holders of record of such Common
Stock.

         ss. 5.   Limitation of Liability; Not Stockholders; Rights of the
Holder.

         No provision of this Warrant shall be construed as conferring upon the
holder hereof the right to vote or to consent or to receive dividends or to
receive notice as a stockholder in respect of meetings of stockholders for the
election of directors of the Company or any other matter whatsoever as
stockholders of the Company. No provision hereof, 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 purchase price or as a stockholder of the
Company, whether such liability is asserted by the Company, creditors of the
Company or others.

         Without limiting the foregoing or any remedies available to the holder
hereof, the holder will be entitled to specific performance of the obligations
hereunder, and injunctive relief against actual or threatened violations of the
obligations of any person subject to, this Warrant.


                                       7
<PAGE>   8


         Upon exercise of this Warrant, the holders of the Warrant Shares shall
have and be entitled to exercise, together with all other holders of
Registrable Securities possessing Registration Rights under the Registration
Rights Agreement dated as of April 29, 2000 and all successor agreements (the
"RRA"), the rights of registration granted under the RRA to Registrable
Securities (with respect to the shares issued upon exercise of this Warrant).

         ss. 6.   Loss, Destruction, etc, of Warrants.

         Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, mutilation or destruction of any Warrant, and in the case of any
such loss, theft or destruction upon delivery of a bond of indemnity in such
form and amount as shall be reasonably satisfactory to the Company, or in the
event of such mutilation upon surrender and cancellation of the Warrant, the
Company will make and deliver a new Warrant, of like tenor, in lieu of such
lost, stolen, destroyed or mutilated Warrant. Any Warrant issued under the
provisions of this Section 6 in lieu of any Warrant alleged to be lost,
destroyed or stolen, or of any mutilated Warrant, shall constitute an original
contractual obligation on the part of the Company.

         ss. 7.   Adjustment.

                  The number of Warrant Shares and the Exercise Price shall be
subject to adjustment from time to time or upon exercise as provided in this
Section 7.

         (a)      Split, Subdivision or Consolidation of Shares, Adjustment to
Initial Conversion Ratio of Series D Preferred Stock.

                  (i)      If the Company shall split, subdivide or combine the
securities as to which purchase rights exist under this Warrant, into a
different number of securities of the same class, the number of Warrant Shares
after such consolidation or subdivision will be increased or reduced, as the
case may be, such increase or decrease, as the case may be, to become effective
immediately after the opening of business on the day following the day upon
which such subdivision or combination becomes effective, and in each case, the
Exercise Price shall be adjusted accordingly. The holder hereof will not be
entitled to receive a fraction of a share of stock.

                  (ii)     At such time as the Company designates the Series D
Preferred Stock, if the initial conversion ratio between the Series D Preferred
Stock and the Common Stock is not 1:1, the initial Exercise Price for the
Series D Preferred Stock shall be adjusted proportionally as of the date of
designation of the Series D Preferred Stock.

         (b)      Stock Dividends. In the event that the holders of the
securities as to which purchase rights under this Warrant exist shall have
received or become


                                       8
<PAGE>   9


entitled to receive, without payment therefor, other or additional stock or
securities or property (other than cash) of the Company by way of dividend,
then in each case, the this Warrant shall represent the right to acquire, in
addition to the number of Warrant Shares indicated in the caption of this
Warrant, and without payment of any additional consideration therefor, the
amount of such other securities or property (other than cash) of the Company to
which the holder hereof would have been entitled had this Warrant been
exercised prior to the distribution of the dividend and had thereafter such
holder retained such shares and/or all other additional stock available to it
during the period prior to the exercise of this Warrant, giving effect to all
adjustments called for in this Section 7, and in each case, the Exercise Price
shall be adjusted accordingly.

         (c)      Merger or Reorganization, etc. If at any time while this
Warrant, or any portion thereof, is outstanding and unexpired there shall be
(i) a reorganization (other than a combination, reclassification, exchange or
subdivision of shares otherwise provided for herein), (ii) a merger or
consolidation of the Company with or into another corporation in which the
Company is not the surviving entity, or a reverse triangular merger in which
the Company is the surviving entity but the shares of the Company's capital
stock outstanding immediately prior to the merger are converted by virtue of
the merger into the property, whether in the form of securities, cash, or
otherwise, or (iii) a sale or transfer of the Company's properties and assets
as, or substantially as, an entirety to any other person, then, as a part of
such reorganization, merger, consolidation, sale or transfer, lawful provision
shall be made so that the holder of this Warrant shall thereafter be entitled
to receive upon exercise of this Warrant, during the period specified herein
and upon payment of the Exercise Price then in effect, the number of shares or
other securities or property of the successor corporation resulting from such
reorganization, merger, consolidation, sale or transfer that a holder of the
shares deliverable upon exercise of this Warrant would have been entitled to
receive in such reorganization, consolidation, merger, sale or transfer if this
Warrant had been exercised immediately before such reorganization, merger,
consolidation, sale or transfer, all subject to further adjustment as provided
in this Section. If the per-share consideration payable to the holder hereof
for shares in connection with any such transaction is in a form other than cash
or marketable securities, then the value of such consideration shall be
determined in good faith by the Company's Board of Directors.

         (d)      Adjustment of Number of Warrant Shares Upon Issuance of
Additional Shares of Common. In the event that prior to the exercise of this
Warrant, the Company shall issue Additional Shares of Common (as defined below)
(including Additional Shares of Common deemed to be issued pursuant to Section
7(e)) without consideration or for a consideration per share less than the
Exercise Price in effect on the date of and immediately prior to such issue,
then and in such event, the holder shall, upon the exercise or conversion of
this Warrant, be entitled to receive, without payment of any additional
consideration therefor, the increased number of


                                       9
<PAGE>   10


Warrant Shares equal to $30,000, (y) divided by the product of the existing
Exercise Price (as adjusted) and a fraction (i) the numerator of which is the
sum of (A) the total number of shares of Common Stock issued and outstanding
(on an as converted basis) plus (B) the number of Additional Shares of Common
Shares that can be purchased at the existing Exercise Price for the total
consideration received or deemed to be received for the issuance or deemed
issuance of Additional Shares of Common and (ii) the denominator of which is
the Common Stock issued and outstanding (on an as converted basis) plus the
number of Additional Shares of Common issued or deemed to be issued in the new
issuance or deemed issuance.

         (e)      Issue of Securities Deemed Issue of Additional Shares of
Common -- Options and Convertible Securities. In the event that prior to the
exercise of this Warrant, the Company shall issue any Options or Convertible
Securities (as those terms are defined below) (other than Options or
Convertible Securities which are not Additional Shares of Common) or shall fix
a record date for the determination of holders of any class or series of
securities entitled to receive any such Options or Convertible Securities, then
the shares of Common issuable upon the exercise of such Options or, in the case
of Convertible Securities and Options therefor, the conversion or exchange of
such Convertible Securities, shall be deemed to be Additional Shares of Common
issued as of the time of such issue or, in case such a record date shall have
been fixed, as of the close of business on such record date; provided, that in
any such case in which Additional Shares of Common are deemed to be issued:

                  (i)      no further adjustment in the number of shares shall
be made upon the subsequent issue of Convertible Securities or shares of Common
upon the exercise of such Options or conversion or exchange of such Convertible
Securities;

                  (ii)     if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the Company, or decreases in the number of shares of
Common issuable, upon the exercise, conversion or exchange thereof, the number
of shares computed upon the original issue thereof (or upon the occurrence of a
record date with respect thereto), and any subsequent adjustments based
thereon, shall, provided that no shares of Common have theretofore been issued
with respect to such Options or Convertible Securities, upon any such increase
or decrease becoming effective, be recomputed to reflect such increase or
decrease insofar as it affects such Options or the rights of conversion or
exchange under such Convertible Securities;

                  (iii)    no readjustment pursuant to clause (ii) above shall
have the effect of decreasing the number of shares to an amount which is less
than the greater of (1) such number on the original adjustment date with
respect to such deemed issuance of Additional Shares of Common, or (2) such
number that would have resulted from any issuance of Additional Shares of
Common between such original adjustment date and such readjustment date; and


                                      10
<PAGE>   11


                  (iv)     if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any decrease in the
consideration payable to the Company upon the exercise, conversion or exchange
thereof, the number computed upon the original issue thereof (or upon the
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such decrease becoming effective, be
recomputed to reflect such decrease insofar as it affects such Options or the
rights of conversion or exchange under such Convertible Securities.

         (f)      Special Definitions. For purposes of Sections 7(d) through
(i), the following definitions shall apply:

                  (i)      "OPTION" shall mean rights, options or warrants to
subscribe for, purchase or otherwise acquire either Common or Convertible
Securities.

                  (ii)     "COMMON" shall mean (i) the Company's presently
authorized Common Stock as such class exists on the date of issuance of this
Warrant, and (ii) stock of the Company of any class or series thereafter
authorized that ranks, or is entitled to a participation, as to assets or
dividends, substantially on a parity with Common Stock.

                  (iii)    "CONVERTIBLE SECURITIES" shall mean any evidences of
indebtedness, shares or other securities directly or indirectly convertible
into or exchangeable for Common.

                  (iv)     "ADDITIONAL SHARES OF COMMON" shall mean all shares
of Common issued (or, pursuant to Section 7(e), deemed to be issued) by the
Company after the date hereof and prior to the exercise of this Warrant, other
than:

                           (A)      options issued at an exercise price per
share no less than $1.80 (as adjusted for stock splits, consolidations or stock
dividends) to officers, employees or directors of the Company under any stock
option plan adopted by the Board of Directors of the Company; provided,
however, that any shares covered by such options or rights plus any such shares
issued (without duplication as to shares issued under options) in excess of
5,500,000 shares of Common Stock as constituted on the date of issuance of this
Warrant (as adjusted for stock splits, consolidations or stock dividends) shall
be deemed to be Additional Shares of Common;

                           (B)      shares issued as a dividend or distribution
on Common Stock or any event for which adjustment is made pursuant to Sections
7(a) and (b) hereof;

                           (C)      shares issued upon conversion of
Convertible Securities; or


                                      11
<PAGE>   12


                           (D)      shares issued by way of dividend or other
distribution on (1) shares excluded from the definition of Additional Shares of
Common by the foregoing clauses (A) through (C) or (2) shares of Common so
excluded under this clause (D).

         (g)      No Adjustment of Number of Warrant Shares or Exercise Price.
No adjustment in the number of Warrant Shares or Exercise Price shall be made
in respect of the issuance of Additional Shares of Common unless the
consideration per share for an Additional Share of Common issued or deemed to
be issued by the Company is less than the Exercise Price in effect on the date
of, and immediately prior to, the issue of such Additional Share of Common.

         (h)      Effect of "Split-up or "Split-down" on "deemed issued"
shares. Upon the effective or record date for any subdivision or combination of
the Common Stock of the character described in Section 7(a), including the
issuance of a stock dividend which is treated as such a subdivision under
Section 7(b), the number of the shares of Common Stock which are at the time
deemed to have been issued by virtue of Section 7(e), but have not actually
been issued, shall be deemed to be increased or decreased proportionately.

         (i)      Computation of Consideration. For the purposes of this
Section 7:

                  (i)      The consideration received by the Company upon the
actual issuance of Additional Shares of Common shall be deemed to be the sum of
the amount of cash and the fair value of property (as determined in good faith
by resolution of the Board of Directors of the Company as at the time of issue
or "deemed issue" in the case of the following paragraph (ii)) received or
receivable by the Company as the consideration or part of the consideration (v)
at the time of issuance of the Common, (w) for the issuance of any rights or
options upon the exercise of which such Common was issued, (x) for the issuance
of any rights or options to purchase Convertible Securities upon the conversion
of which such Common was issued, (y) for the issuance of the Convertible
Securities upon conversion of which such Common was issued, and (z) at the time
of the actual exercise of such rights, options or conversion privileges upon
the exercise of which such Common was issued, in each case without deduction
for commissions and expenses incurred by the Company for any underwriting of,
or otherwise in connection with the issue or sale of, such rights, options,
Convertible Securities or Common, but after deduction of any sums paid by the
Company in cash upon the exercise of, and pursuant to, such rights, options or
conversion privileges in respect of fractional shares of Common; and

                  (ii)     The consideration deemed to have been received by
the Company for Additional Shares of Common deemed to be issued pursuant to
rights, options and conversion privileges by reason of transactions of the
character


                                      12
<PAGE>   13


described in Section 7(e) shall be the consideration (determined as provided in
the foregoing paragraph (i)) that would be received or receivable by the
Company at or before the actual issue of such shares of Common so deemed to be
issued, if all rights, options and conversion privileges necessary to effect
the actual issue of the number of shares deemed to have been issued had been
exercised (successively exercised in the case of rights or options to purchase
Convertible Securities), and the minimum consideration received or receivable
by the Company upon such exercise had been received; all computed without
regard to the possible future effect of anti-dilution provisions on such
rights, options and/or conversion privileges.

         (j)      Statement of Adjustment. Whenever the number of Warrant
Shares is adjusted pursuant to any of the foregoing provisions of this Section
7, the Company shall promptly prepare a written statement signed by the
President of the Company, setting forth the adjustment, determined as provided
in this Section, and in reasonable detail the facts requiring such adjustment
and the calculation thereof. Such statement shall be filed among the permanent
records of the Company and a copy thereof shall be furnished to the holder of
this Warrant without request and shall at all reasonable times during business
hours be open to inspection by holders of the Warrants.

         (k)      Determination by the Board of Directors. All determinations
by the Board of Directors of the Company under the provisions of this Section 7
shall be made in good faith.

         ss. 8.   Governing Law.

         This Warrant shall be governed by the laws of the State of Delaware,
without giving effect to the rules respecting conflict of law.

         ss. 9.   Entire Agreement; Modification; Waiver. This Warrant
constitutes the entire agreement between the parties pertaining to the subject
matter herein, and supersedes all prior and contemporaneous agreements,
representations, and understandings of the parties. No supplement,
modification, or amendment of this Warrant shall be binding unless executed in
writing by the parties hereto. No waiver of any of the provisions of this
Warrant shall be deemed, or shall constitute, a waiver of any other provision,
whether or not similar, nor shall any waiver constitute a continuing waiver.

         IN WITNESS WHEREOF, the Company has caused this Warrant to be signed
in its name by a duly authorized officer.
