                             --------------------

                                   RECITALS

     This Agreement is entered into on the basis of the following facts,
understandings and intentions of the parties:

     A.   The Corporation has developed a proprietary system for offering
coupons and other direct promotions over the Internet (the "Business"). The
Investor has developed a concept that provides a service to retailers and
consumers that has some common features to the Business and in connection
therewith has developed contacts, technologies, ideas, tools and supporting
materials which could provide enhancement of and support to the Business.

     B.  The Investor desires to acquire common stock of the Corporation for the
monetary consideration set forth in this Agreement (the "Investment"), to
contribute contacts, technologies, ideas, tools and supporting materials to the
Corporation in accordance with the Initial Business Plan attached hereto as
Exhibit 6.1, as the same may from time to time be hereafter amended by action of
-----------
the Board of Directors (the "Business Plan"), and to participate in directing
and operating the Business, all in consideration of the commitments made by the
Corporation in this Agreement.

     C.   In connection with the Investment, the Corporation shall issue to the
Investor on a fully diluted basis an amount of shares (the "Investment Shares")
of the Corporation's common stock (the "Common Stock"), with the voting powers,
designations, preferences, limitations, and relative participating, optional or
other rights set forth in this Agreement, the Articles of Incorporation of the
Corporation, as amended (the "Articles of Incorporation") attached as Exhibit A,
                                                                      ---------
and the Shareholders Agreement attached hereto as Exhibit 6.6, on the terms and
                                                  -----------
conditions set forth in this Agreement and the Shareholders Agreement.

                                   ARTICLE I

                     ISSUANCE AND SALE OF THE COMMON STOCK

     1.1  Investment Amount; Authorization of Issuance and Reservation of Common
          ----------------------------------------------------------------------
          Stock.
          -----

          (a)  The Investment shall be made in four phases (each a "Phase", and
     collectively the "Phases") as set forth in Sections 1.2 and 1.3 herein, for
                                                ------------     ---
     an aggregate purchase price of U.S. $18,500,000.

          (b)  Subject to the terms and conditions hereof, the Corporation has
     authorized the issuance of up to Thirty percent (30%) of its Common Stock,
     without par value, on a fully diluted basis (the "Fully Diluted Shares") in
     four Phases at the purchase price for each Phase set forth below. The Fully
     Diluted Shares means, immediately following any issuance of Common Stock to
     the Investor hereunder, all of the Corporation's issued and outstanding
     Common Stock and all shares of Common Stock issuable upon exercise of, or
     pursuant to, all outstanding rights, options, warrants, preemptive rights,
     conversion rights or agreements for the purchase, acquisition or receipt
     from the Corporation of any shares of its Common Stock.

          (c)  The Corporation shall reserve that number of shares of Common
     Stock to ensure the availability at all times of Thirty percent (30%) of
     the Fully Diluted Shares for issuance to the Investor and shall reserve
     additional shares of Common Stock for issuance to the Investor, all as is
     required pursuant to the terms of this Agreement in order to comply with
     the provisions of this Agreement for issuance of Common Stock to the
     Investor.

     1.2  Phase One.
          ---------

          (a)  Subject to the terms and conditions herein, and in reliance on
     the representations, warranties and agreements contained herein, the
     Corporation shall issue and sell to the Investor that number of shares of
     Common Stock equal to Ten percent (10%) of the Fully Diluted Shares for a
     purchase price of U.S $5,000,000 (the "Phase One Shares").

          (b)  The purchase and sale of the Phase One Shares shall occur at a
     closing (the "Phase One Closing") to be held as soon as is practicable, but
     in any event, not later than June 1, 1998, or such other time and place as
     shall be mutually agreed upon by the Corporation and the Investor.

     1.3  Phases Two, Three and Four.
          --------------------------

     Following the Phase One Closing, the remainder of the Investment, totaling
U.S. $13,500,000, shall be staged in three Phases pursuant to the terms and
subject to the conditions of this Section 1.3, for the following purchase prices
                                  -----------
such that after issuance, the Investor shall own the following percentages of
the Fully Diluted Shares in addition to any percentages of Fully Diluted Shares
owned prior to any such issuance:

                                       % of Fully Diluted Shares
                                       -------------------------
Phase                Purchase Price    after issuance to the Investor
-----                --------------    ------------------------------

Phase Two            US $5,000,000     7.5%
Phase Three          US $5,000,000     7.5%
Phase Four           US $3,500,000     5.0%


     (a)  Upon the Corporation achieving the milestones for each Phase set forth
     in the Business Plan (a "Milestone"), the Investor shall have the option to
     invest the full amounts and for the percentages of Fully Diluted Shares as
     set forth above. The decision as to whether or not to invest in any Phase
     under this Section 1.3 shall be determined by the Investor in its sole
                -----------
     discretion, provided however, if the Investor fails to exercise the option
     to invest in any Phase, the Investor shall be deemed to have waived the
     right to purchase that percentage of Fully Diluted Shares available to it
     in the Phase in which it did not invest, but such waiver shall not affect
     any further unexercised options as to a Phase following the Phase not
     exercised. The option for each Phase shall be exercised as follows:

               (i)   Within thirty (30) days after the date the Corporation must
          achieve the Milestone for a Phase, the Corporation shall notify the
          Investor, in writing, whether or not the Milestone has been achieved
          (the "Investment Notice") and that the Investor must give notice to
          exercise the option or not exercise the option as to that Phase (the
          "Option Notice").

               (ii)  Within fifteen (15) days after the date the Investor
          receives the Investment Notice for Phase Two (the "Phase Two Election
          Period"), if the Investor elects to exercise its option to invest, the
          Investor shall notify the Corporation of its decision to invest and
          shall deliver the Option Notice to the Corporation. The Corporation's
          failure to receive the Option Notice for Phase Two within the Phase
          Two Election Period shall be deemed receipt of notice from the
          Investor of its election not to invest in Phase Two. If the Investor
          delivers the Option Notice which states an election to invest within
          the Phase Two Exercise Period, the Investor shall have forty-five (45)
          days after the Phase Two Election Period to deliver the purchase price
          to the Corporation (the "Phase Two Due Date").

                                       3
<PAGE>

          (iii)  Within thirty (30) days after the date of the Investment
          Notice for Phase Three or Phase Four (the "Phase Three or Phase Four
          Exercise Period"), if the Investor elects to exercise its option to
          invest, the Investor shall notify the Corporation of its decision to
          invest and shall deliver the Option Notice and, prior to the end of
          the Phase Three or Phase Four Exercise Period, deliver the purchase
          price for Phase Three or Phase Four to the Corporation. The
          Corporation's failure to receive the Option Notice for Phase Three or
          Phase Four within the respective Phase Three or Phase Four Exercise
          Period shall be deemed receipt of notice from the Investor of its
          election not to invest. If the Option Notice states an election to
          invest within the Phase Three or Phase Four Exercise Period, but the
          Investor fails to deliver the applicable purchase price to the
          Corporation prior to the end of the Phase Three or Phase Four Exercise
          Period, the Corporation shall notify the Investor of the failure to
          deliver the purchase price and the Investor shall have a grace period
          of seven (7) days after such notice to deliver the purchase price to
          the Corporation (the "Phase Three or Phase Four Grace Period").

     (b)  The Corporation's failure to achieve a Milestone for any Phase will
     not in any way affect the Investor's right to invest in that or any other
     Phase whether or not the Corporation achieves or fails to achieve the
     Milestone for such other Phase, except if the Corporation or the Investor
     exercises their respective rights, if applicable, under Sections
                                                             --------
     1.3(c)(ii), 1.3(d)(ii), 1.3(e)(ii) or 1.3(g)(i), in which event the
     -----------------------------------------------
     Investor shall have no further rights to exercise any option for any Phase
     after such right is exercised.

     (c)  In the event the Corporation fails to achieve the Milestone for Phase
     Two, and the Investor elects in its sole discretion not to invest in Phase
     Two, all of the following shall apply:

               (i)  The Corporation shall be entitled to raise capital through
          the issuance of debt or equity. If it raises capital through the
          issuance of equity, Investor shall be pro-rata diluted with all other
          shareholders of the Corporation; provided, however, the Investor shall
          have the right to purchase equity in such offering, at the per share
          price in such offering, less discounts and commissions, in an amount
          necessary to maintain its then percentage equity interest of the Fully

     Corporation in its sole discretion:

               (i)    The Corporation shall be entitled to raise capital through

          deliver the purchase price to the Investor within the period provided
          by Section 1.3(d)(ii) above, any action taken by the Corporation under
          Section 1.3(d)(ii)-(iv) above, shall be deemed void and of no effect.

     (e)  In the event the Corporation fails to achieve a Milestone for either

          Three or Phase Four Put Notice") at a price equal to ninety percent
          (90%) of the aggregate purchase price paid by the Investor for the
          Investment. Upon receipt of the Phase Three or Phase Four Put Notice,
          the Corporation shall be obligated to redeem the Investor's entire
          equity interest for said price, on a date selected by the Corporation
          (but in no event later than six (6) months from the date of the Phase
          Three or Phase Four Put Notice); and

               (iii) In the event the Corporation raises capital through the

licenses for the Corporation's technology (including technology documentation

an Affiliate of the Investor (as designated by the Investor), for the limited
purposes and uses of maintaining the core business activities of the Investor or
such Affiliate (the "Core Business") which have integrated (without infringing
upon the Intellectual Property Rights of the Corporation) some or all aspects of
the Corporation's technology services into its active business operations (the

faith the specific terms and conditions of the License and conclude such
negotiations within sixty (60) days after delivery of such Option Notice. The
failure of the parties to agree in good faith upon the terms and conditions of
the License within such sixty (60) day period shall not excuse either party from
performing any other obligations, or limit either party's remedies, under this
Agreement (including those set forth in Sections 1.3(e), 1.3(f), and 1.3(g)). A

performance under this Section 1.6, or damages arising from a breach of this

     The "Initial Public Offering" shall mean the Corporation's initial public
offering pursuant to an effective registration statement under the Securities

               (b)  Within forty-five (45) days after the date of the Private
          Offering Notice, the Investor may elect by written notice to the
          Corporation to purchase or obtain, a portion of the Private Offering,
          at a discount of ten percent (10%) off the price specified in the
          Private Offering Notice; provided however, that: (i) the Investor's

               (c)  Following the expiration of the forty-five (45) day period
          set forth in subsection (b) above, the Corporation may make the
          Private Offering to third parties for the portion of the Private
          Offering that the Investor was not entitled to purchase and for the
          remaining portion of the Private Offering that the Investor did not
          properly elect to purchase in accordance with this Section 2.1;

          provided however, that all such offers to third persons shall be at a
          price not less than, and upon terms no more favorable to the offeree
          than, those specified in the Private Offering Notice. If the
          Corporation does not close the sale of the interests offered in the
          Private Offering within any time limit set forth in the Private
          Offering, the right provided hereunder shall be deemed to be revived,
          and that portion of the Private Offering which was subject to the
          Investor's rights under this Section 2.1 shall not be offered or
                                       -----------

                                                            -----------
          not be applicable (i) to the issuance or sale of shares of Common
          Stock (as adjusted to reflect any stock splits, combinations or other
          events involving the Common Stock) to employees, consultants or

          of convertible or exercisable securities of the Corporation, (iv) to
          securities issued in connection with any acquisition or business
          combination transaction approved by the Board of Directors of the
          Corporation, or (v) to securities issued in connection with equipment
          lease financings or other financings with commercial lenders, or in
          strategic transactions involving the Corporation and other entities,

in the ordinary course of business for fair value and accounts and notes
receivable paid in full since the date of the Interim Balance Sheet), free and
clear of all encumbrances, except for those encumbrances set forth in the

condition and repair (normal wear and tear excepted), are adequate and suitable
for the uses for which they are used in the Corporation's business, are not
subject to any condition which interferes with the economic value or use
thereof, and constitute all assets necessary to permit the Corporation to carry

(iii) liens for taxes not yet due and payable; and (iv) landlords liens, if any,
relating to leases.

               AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
               ACT OF 1933, AS AMENDED (THE "ACT"). THEY MAY NOT
               BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED
               OR OTHERWISE TRANSFERRED TO ANY RESIDENT OF THE
               UNITED STATES FOR A PERIOD OF TWELVE MONTHS IN THE

               TO THE SECURITIES UNDER THE ACT AND APPLICABLE
               STATE SECURITIES LAWS OR UNLESS AN OPINION OF
               COUNSEL ACCEPTABLE TO THE CORPORATION HAS BEEN
               OBTAINED TO THE EFFECT THAT THE PROPOSED TRANSFER
               COMPLIES WITH REGULATION S UNDER THE ACT OR OTHER

          (b)  The holder of any of the Investment Shares by acceptance thereof
     agrees, prior to any transfer of any of the Investment Shares, to give
     written notice to the Corporation of such holder's intention to effect such
     transfer and to comply in all other respects with the provisions of this
     Section.  Each such notice shall describe the manner and circumstances of
     the proposed transfer.  Upon request by the Corporation, the holder
     delivering such notice shall deliver a written opinion, addressed to the
     Corporation, of counsel for the holder of the Investment Shares, stating
     that in the opinion of such counsel (which opinion and counsel shall be
     reasonably satisfactory to the Corporation) such proposed transfer does not
     involve a transaction requiring registration or

                                       26

     qualification of such Securities under the Securities Act or the securities
     or "blue sky" laws of any state of the United States. Such holder of the

     that such proposed transfer involves a transaction requiring registration
     or qualification of such securities under the Securities Act or the
     securities or "blue sky" laws of any state of the United States and
     requests an opinion with respect to such issue within five days after
     delivery of such notice, or, if it requests such opinion, does not
     reasonably object to such transfer within five days after delivery of such
     opinion. Each certificate or other instrument evidencing the securities
     issued upon the transfer of any of the Investment Shares (and each
     certificate or other instrument evidencing any untransferred balance of
     such Securities) shall bear the legend set forth in Section 8.2(a) above
                                                         --------------

     is not required by the applicable provisions of the Securities Act; or (ii)
     the Corporation shall have waived the requirement of such legends or any
     other legends deemed necessary by the Corporation.

          (c)  Notwithstanding the foregoing provisions of this Section 8.2, the
                                                                -----------

     Securities shall cease and terminate when (i) any of the Investment Shares
     are sold or otherwise disposed of (A) pursuant to an effective registration
     statement under the Securities Act or (B) in a transaction contemplated by
     Section 8.2  (b) above which does not require that the Securities so
     -----------
     transferred bear the legend set forth in Section 8.2 (a) hereof; or (ii)
                                              -----------
     the holder of such Securities has met the requirements for transfer of such
     Securities under Rule 144 or any successor Rule.  Whenever the restrictions
     imposed by this Section 8.2 shall terminate, the holder of any of the
                     -----------
     Investment Shares as to which such restrictions have terminated shall be
     entitled to receive from the Corporation, without expense, a new
     certificate not bearing the restrictive legend set forth in Section 8.2(a)
                                                                 --------------
