                                    ARTICLE 1
                              EXERCISE OF WARRANTS

         SECTION 1.1. METHOD OF EXERCISE. Subject to the provisions of Article 3
below, to exercise this Warrant in whole or in part, the Holder shall deliver to
the Company at the Warrant Office designated pursuant to Section 2.1: (i) 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 shares of Common Stock to be purchased;
(ii) a certified or official bank check payable to the order of the Company in
an amount equal to the aggregate Current Warrant Price of the number of shares
of Common Stock being purchased; and (iii) this Warrant. The Company shall as
promptly as practicable, and in any event within 10 days after receipt by the
Company of such notice, execute and deliver or cause to be executed and
delivered, in accordance with said notice, a certificate or certificates
representing the aggregate number of shares of Common Stock specified in said
notice. The stock certificate or certificates so delivered shall be in the
denomination as may be specified in said notice and shall be issued in the name
of such holder or such other name as shall be designated in said 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 shares as of the date the
consideration specified for such shares 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
shares of Common Stock called for by this Warrant, which new Warrant shall in
all other respects be identical with 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, issuance and delivery of such stock
certificates and any new Warrant, except that, in case such stock certificates
or new Warrant 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 which
shall be payable upon the issuance of such stock certificate or certificates or
any new Warrant shall be paid by the holder hereof at the time of delivering the
notice of exercise mentioned above or promptly upon receipt of a written request
of the Company for payment of the same.

         SECTION 1.2. WARRANT SHARES TO BE FULLY PAID AND NONASSESSABLE. All
shares of Common Stock issued upon the exercise of this Warrant shall be validly
issued, fully paid and nonassessable and, if the Common Stock is then listed on
a securities exchange, shall be duly listed thereon, subject to registration
under the Exchange Act.

         SECTION 1.3. NO FRACTIONAL SHARES TO BE ISSUED, The Company shall not
be required upon any exercise of this Warrant to issue a certificate
representing any fraction of a share of Common Stock, but, in lieu thereof,
shall pay Holder cash in an amount equal to a corresponding fraction (calculated
to the nearest 1/100 of a share) of the Current Market Price of one share of
Common Stock as of the date of receipt by the Company of notice of exercise of
this Warrant.

         SECTION 1.4. LEGEND ON WARRANT SHARES. Each certificate for shares
initially issued upon exercise of this Warrant, unless at the time of exercise
such Warrant Shares are registered under the Act, shall bear a legend in
substantially the following form (and any additional legend required by any
securities exchange upon which such Warrant Shares may, at the time of such
exercise, be listed) on the face thereof:

         "The securities represented by this certificate have not been
registered under the Securities Act of 1933, as amended, or the laws of any
state and may not be sold or otherwise transferred except

                                       2
<PAGE>   3

pursuant to an effective registration statement or the written opinion of
counsel to World Commerce Online, Inc., that such registration is not required.

         Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon completion
of: (i) a public distribution pursuant to a registration statement; or (ii) an
exempt sale pursuant to Rule 144 or Rule 144A under the Act of the securities
represented thereby) shall also bear such legend.

                                    ARTICLE 2
                       WARRANT OFFICE; OWNERSHIP, TRANSFER
                                   OF WARRANT

         SECTION 2.1. WARRANT OFFICE. The Company shall maintain an office for
certain purposes specified herein (the "Warrant Office"), which office shall
initially be the Company's office at 9677 Tradeport Drive, Orlando, Florida
32827, and may subsequently be such other office of the Company or of any
transfer agent of the Common Stock in the continental United States as to which
written notice has previously been given to all of the Warrantholders.

         SECTION 2.2. OWNERSHIP OF WARRANT. The Company may deem and treat the
person in whose name this Warrant is initially registered as the holder and
owner hereof (notwithstanding any notations of ownership or writing hereon made
by anyone other than the Company) for all purposes and shall not be affected by
any notice to the contrary, until presentation of evidence satisfactory to the
Company that this Warrant has been transferred as provided in Section 2.3.

         SECTION 2.3. TRANSFER OF WARRANT. This Warrant and all rights hereunder
may not be alienated, assigned, pledged or otherwise transferred, in whole or in
part, other than by Holder to an Affiliate of Holder, and any attempt to make
any transfer other than by Holder to an Affiliate shall be null and void. The
term "Affiliate" shall mean, with respect to Holder, any other entity that,
directly or indirectly through one or more intermediaries, controls, is
controlled by, or is under common control with, such Holder.

                                    ARTICLE 3
                            ANTI-DILUTION PROVISIONS

         SECTION 3.1. ADJUSTMENT OF CURRENT WARRANT PRICE AND NUMBER OF SHARES
PURCHASABLE. The Current Warrant Price and the number of shares of Common Stock
purchasable upon the exercise of each Warrant shall be subject to adjustment
from time to time as hereinafter provided in this Article 3. Upon each
adjustment of the Current Warrant Price, the holder of this Warrant shall
thereafter be entitled to purchase at the Current Warrant Price resulting from
such adjustment, the number of shares (calculated to the nearest whole share) of
Common Stock calculated by multiplying the Current Warrant Price in effect
immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment and dividing the product
thereof by the Current Warrant Price resulting from such adjustment.

         SECTION 3.2. EFFECT OF "SPLIT-UPS" AND STOCK DIVIDENDS. In case at any
time or from time to time the Company shall subdivide or combine as a whole, by
reclassification, by the issuance of a stock dividend on the Common Stock
payable in Common Stock, or otherwise, the number of shares of Common Stock then
outstanding into a greater or lesser number of shares of Common Stock, with or
without par value, the Current Warrant Price shall be reduced or increased (as
applicable) proportionately. The issuance of such a stock dividend shall be
treated as a subdivision of the whole

                                       3
<PAGE>   4

number of shares of Common Stock outstanding immediately prior to such dividend
into a number of shares equal to such whole number of shares so outstanding plus
the number of shares issued as a stock dividend. Upon any such adjustment, the
number of shares shall be rounded upward to the nearest whole share.

                                    ARTICLE 4

meaning of the Act) of the Warrant or Warrant Shares; because the Warrant and
Warrant Shares will not have been registered under the Act, the Company will not

issuance of this Warrant and the Warrant Shares and to obtain any additional
information concerning the Company which they have requested; and

         (c) The Company has made available for inspection by them various
documents connected with the Company's business and has not refused in any way
to permit them to inspect any document requested by them to be inspected.

        No provision of this Warrant shall be construed as conferring upon the
holder hereof the right to vote, consent, receive dividends or receive notice
other than as herein expressly provided in respect of meetings of stockholders
for the election of directors of the Company or any other matter whatsoever as a
stockholder of the Company. No provision hereof, in the absence of affirmative
action by the holder hereof to purchase shares of Common Stock, 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 of any Warrant
Shares or as a stockholder of the Company, whether such liability is asserted by
the Company or by creditors of the Company.

                                    ARTICLE 9

        Upon receipt of evidence 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
Article 9 in lieu of any Warrant alleged to be lost, destroyed or stolen, or in
lieu of any mutilated Warrant, shall constitute an original contractual
obligation on the part of the Company.
