                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Except as set forth on EXHIBIT B attached hereto (the "COMPANY

laws of the jurisdiction of its incorporation or organization, as the case may
be, and has the requisite corporate power and authority to own, lease and
operate its properties and to carry on its business as it is now being
conducted. Company and each Company Subsidiary is duly qualified or licensed to
do business, and is in good standing (to the extent applicable), in each
jurisdiction where the character of the properties owned, leased or operated by
it or the nature of its business makes such qualification or licensing
necessary, except for such failures to be so qualified or licensed and in good
standing that could not reasonably be expected to have, individually or in the
aggregate, any change in or effect on the business of Company and the Company
Subsidiaries that, individually or in the aggregate (taking into account all
other such changes or effects), is, or is reasonably likely to be, materially
adverse to the business, assets, liabilities, financial condition, results of
operations or prospects of Company and the Company Subsidiaries, taken as a
whole (a "MATERIAL ADVERSE EFFECT")

                  (b) Section 3.1 of the Company Disclosure Schedule sets forth,
as of the date of this Agreement, a true and complete list of each Company
Subsidiary, together with (i) the jurisdiction of incorporation or organization

Company Subsidiary and (ii) an indication of whether each Company Subsidiary is

Exchange Act of 1934, as amended (the "EXCHANGE ACT"). Except as set forth in
Section 3.1 of the Company Disclosure Schedule, neither Company nor any Company
Subsidiary owns an equity interest in any partnership or joint venture
arrangement or other business entity.

         3.2 CERTIFICATE OF INCORPORATION AND BYLAWS. The copies of Company's
Amended and Restated Certificate of Incorporation (the "RESTATED CERTIFICATE")

Certificate or bylaws.

         3.3 CAPITALIZATION. The authorized capital stock of Company consists
of 100,000,000 shares of Company Common Stock and 20,000,000 shares of preferred

future issuance pursuant to Company Stock Options, of which 4,036,487 and
668,281 shares of Company Common Stock are reserved for future issuance

Option, the grant date of each Company Stock Option, and the number of shares
of Company Common Stock for which each Company Stock Option is exercisable
and the exercise price of each Company Stock Option are set forth in Section
3.3 of the Company Disclosure Schedule. Except for shares of Company Common
Stock issuable pursuant to Company Stock Plans, there are no options,
warrants or other rights, agreements, arrangements or commitments of any
character to which Company is a party or by which Company is bound relating
to the issued or unissued capital stock of Company or any Company Subsidiary
or obligating Company or any Company Subsidiary to issue or sell any shares
of capital stock of, or other equity interests in, Company or any Company
Subsidiary. All shares of Company Common Stock subject to issuance as
aforesaid, upon issuance prior to the Effective Time on the terms and
conditions specified in the instruments pursuant to which they are issuable,
will be duly authorized, validly issued, fully paid and nonassessable. There
are no outstanding contractual obligations of Company or any Company
Subsidiary to repurchase, redeem or otherwise acquire any shares of Company
Common Stock or any capital stock of any Company Subsidiary. Each outstanding
share of capital stock of each Company Subsidiary is duly authorized, validly
issued, fully paid and nonassessable and each such share owned by Company or
another Company Subsidiary is free and clear of all security interests,
liens, claims, pledges, options, rights of first refusal, agreements,
limitations on Company's or such other Company Subsidiary's voting rights,
charges and other encumbrances of any nature whatsoever. There are no
material outstanding contractual obligations of Company or any Company
Subsidiary to provide funds to, or make any material investment (in the form
of a loan, capital contribution or otherwise) in, any Company Subsidiary or
any other person.

restrictions described in the Company's Restated Certificate; the Common Stock
issuable upon exercise of the Warrant has been duly and validly reserved and,
when issued in compliance with the provisions of the Restated Certificate, will

thereof) other than any liens or encumbrances created by or imposed upon the
holders; provided, however, that the Shares may be subject to restrictions on
transfer under state or federal securities laws and restrictions set forth in

preemptive rights or rights of first refusal.

         3.5      NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

conflict with or violate any provision of the certificate of incorporation or
bylaws of Company or any equivalent organizational documents of any Company
Subsidiary, (ii) assuming that all filings and notifications described in

others any right of termination, amendment, acceleration or cancellation of, or
result in the creation of a lien or other encumbrance on any property or asset
of Company or any Company Subsidiary pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation.

                  (b) The execution and delivery of this Agreement by Company do

United States generally accepted accounting principles ("U. S. GAAP"), except
for immaterial liabilities or obligations incurred in the ordinary course of
business consistent with past practice since December 31, 1998.

         3.8 ABSENCE OF CERTAIN CHANGES OR EVENTS. Since December 31, 1998,

Effect on the Company, or (z) waiver of any rights of material value or
cancellation or any material debts or claims, (ix) any incurrence of any
material liability (absolute or contingent), except for current liabilities and
obligations incurred in the ordinary course of business consistent with past

with respect to which Company or any Company Subsidiary could otherwise incur
liability under Title IV of ERISA (a "COMPANY ERISA AFFILIATE") has sponsored or
contributed to or been required to contribute to a multiemployer pension plan or

relating to their respective employees, directors or consultants, and (iii) all
plans, programs, agreements and other arrangements of Company and each Company
Subsidiary with or relating to their respective employees, directors or
consultants which contain "change of control" provisions. No payment or benefit
which may be required to be made by Company or any Company Subsidiary or which
otherwise may be required to be made under the terms of any Company Benefit Plan
or other arrangement will constitute a parachute payment under Code Section
280(G)(1), and the consummation of the transactions contemplated by this
Agreement will not, alone or in conjunction with any other possible event
(including termination of employment), (i) entitle any current or former
employee or other service provider of Company or any Company Subsidiary to

forgiveness of indebtedness), except as expressly provided by this Agreement, or
(ii) accelerate the time of payment or vesting, or increase the amount of

of Company, any Company Subsidiary, or any of their respective representatives
or employees has committed any unfair labor practice in connection with the
operation of the respective businesses of Company or any Company Subsidiary, and
there is no charge or complaint against Company or any Company Subsidiary by the

regulations of the NNM, and (ii) where the failure to obtain such consents,
approvals, authorizations or permits, or to make such filings or notifications,
(x) would not prevent the sale of Shares and issuance of Warrant or otherwise
prevent Purchaser from performing their respective obligations under this
Agreement or (y) could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect on Purchaser.

         4.6      SEC FILINGS; FINANCIAL STATEMENTS.

                  (a) Purchaser has made available to Company a correct and
complete copy of each report, schedule, registration statement and definitive
proxy statement filed by Purchaser with the SEC on or after July 1, 1997 (the
"PURCHASER SEC REPORTS"), which are all the forms, reports and documents
required to be filed by Purchaser with the SEC since July 1, 1997. The
Purchaser SEC Reports (A) were prepared in accordance with the requirements
of the Securities Act or the Exchange Act, as the case may be, and (B) did
not at the time they were filed (or if amended or superseded by a filing
prior to the date of this Agreement, then on the date of such filing) contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. None of Purchaser's subsidiaries is required to file any reports
or other documents with the SEC.

                  (b) Each set of consolidated financial statements (including,
in each case, any related notes thereto) contained in the Purchaser SEC Reports
was prepared in accordance with U.S. GAAP applied on a consistent basis
throughout the periods involved (except as may be indicated in the notes thereto
or, in the case of unaudited statements, do not contain footnotes as permitted
by Form 10-Q of the Exchange Act) and each fairly presents the consolidated
financial position of Purchaser and its subsidiaries at the respective dates
thereof and the consolidated results of its operations and cash flows for the
periods indicated, except that the unaudited interim financial statements were
or are subject to normal adjustments which were not or are not expected to be
material in amount.

         4.7 BROKERS. Purchaser has not incurred, nor will it incur, directly
or indirectly, any liability for brokerage or finders' fees or agents'
commissions or any similar charges in connection with this Agreement or any
transaction contemplated hereby.

         4.8 INVESTMENT INTENT; BLUE SKY. Purchaser is acquiring the Shares for
investment for its own account, not as a nominee or agent, and not with the view
to, or for resale in connection with, any distribution thereof. It understands
that the issuance of the Shares and Warrant has not been, and will not be,
registered under the Securities Act by reason of a specific exemption from the
registration provisions of the Securities Act, the availability of which depends
upon, among other things, the bona fide nature of the Purchaser's investment
intent and the accuracy of the Purchaser's representations as expressed herein.
The Purchaser's address set forth in Section 8.3(a) represents


                                       15
<PAGE>

the Purchaser's true and correct state of domicile, upon which the Company may
rely for the purpose of complying with applicable "Blue Sky" laws.

         4.9 RULE 144. Purchaser acknowledges that the Shares must be held
indefinitely unless subsequently registered under the Securities Act or unless
an exemption from such registration is available. Purchaser is aware of the
provisions of Rule 144 promulgated under the Securities Act which permit limited
resale of shares purchased in a private placement subject to the satisfaction of
certain conditions, including, among other things, the existence of a public
market for the shares, the availability of certain current public information
about the Company, the resale occurring not less than one year after a party has
purchased and paid for the security to be sold, the sale being effected through
a "broker's transaction" or in a transaction directly with a "market maker," and
the number of shares being sold during any three-month period not exceeding
specified limitations.

         4.10 NO PUBLIC MARKET. Purchaser understands that no public market now
exists for any of the securities issued by the Company and that the Company has
made no assurances that a public market will ever exist for the Company's
securities.

         4.11 RESTRICTIONS ON TRANSFER; RESTRICTIVE LEGENDS. Purchaser
understands that the transfer of the Shares is restricted by applicable state
and Federal securities laws and by the provisions of the Investor Rights
Agreement, and that the certificates representing the Shares will be imprinted
with legends restricting transfer except in compliance therewith.

         4.12 AUTHORIZATION. All action on the part of the Purchaser's
partners, board of directors, and stockholders, as applicable, necessary for the
authorization, execution, delivery and performance of the Authorized Agreements,
the purchase of and payment for the Shares and the performance of all of the
Purchaser's obligations under the Authorized Agreements has been taken or will
be taken prior to the Closing. The Authorized Agreements, when executed and
delivered by the Purchaser, shall constitute valid and binding obligations of
the Purchaser, enforceable in accordance with their terms, subject to laws of
general application relating to bankruptcy, insolvency and the relief of debtors
and rules of law governing specific performance, injunctive relief or other
equitable remedies; PROVIDED, HOWEVER, that the Purchaser makes no
representation as to the enforceability of the indemnification provisions
contained in the Registration Rights Agreement.

         4.13 ACCREDITED INVESTOR. Purchaser is an "accredited investor" within
the meaning of SEC Rule 501 or Regulation D, as presently in effect. The
Purchaser acknowledges that it has had the opportunity to review this Agreement,
the exhibits and the schedules attached hereto and the transactions contemplated
by this Agreement with its own legal counsel. Purchaser is relying solely on its
own legal counsel and not on the Company or any of the Company's agents for
legal advice with respect to this investment or the transactions contemplated by
this Agreement.

                             ADDITIONAL AGREEMENTS.

         7.1 COVENANT NOT TO SUE. So long as Purchaser, or any of its
subsidiaries, is the owner of record or beneficial owner of at least five
percent of the Company's capital stock or option to purchase capital stock of
the Company (on a fully diluted basis), Purchaser covenants and agrees not to
sue or threaten to sue the Company or any of its vendees, affiliates, licensees,
customers or successors in interest for infringement of any claim of Purchaser's
U.S. Patent No. 5,948,061, or any claim of any United States patent or patent
application, or foreign patent or patent application, that is related to U.S.
Patent No. 5,948,061 or claims priority from U.S. Patent No. 5,948,061 or claims
any device or process or system of delivery, targeting and/or measuring
advertising in a computer network, based upon any act by the Company or any of
its vendees, affiliates, licensees, customers or successors in interest.
Purchaser further promises to impose the covenant of this paragraph on any third
party to whom Purchaser may assign or exclusively license any patent or patent
application covered by this paragraph.

         7.2 GOOD FAITH NEGOTIATION OF A LICENSE. If, at any time following the
Closing Date, Purchaser, or any of its subsidiaries, is no longer the owner of
record or beneficial owner of at least five percent of the Company's capital
stock shares of the capital stock of the Company or options to purchase capital
stock of the Company, then Purchaser agrees that at such time Purchaser will, in
good faith, negotiate with the Company for the Company to obtain a license under
commercially reasonable terms to make, use, sell, offer for sale, import and
otherwise exploit the invention claimed in Purchaser's U.S. Patent No. 5,948,061
or claimed in any United States or foreign patent or patent application that is
related to U.S. Patent No. 5,948,061 or claims priority from U.S. Patent No.
5,948,061 or claims any device or process or system of delivery, targeting
and/or measuring advertising in a computer network.

         7.3 NO ADMISSION OF VALIDITY OR INFRINGEMENT. Nothing in this Section 7
shall be construed as an admission by the Company that Purchaser's U.S. Patent
No. 5,948,061 is valid, enforceable and/or that U.S. Patent No. 5,948,061 is
infringed by the Company.

         7.4 AGREEMENT TO USE DART SERVICES. The Company and Purchaser hereby
covenant that they shall enter into a DART Services Agreement with each other as
soon as practicable after the Effective Date of this Agreement under such terms
as mutually agreed to by the parties. The Company further covenants that to the
extent it uses other services that are in the future made available by
Purchaser, it shall obtain such services from Purchaser, so long as Purchaser
offers such services to the Company on commercially reasonable terms and that
such terms are as favorable as others generally available in the marketplace.

                                    SECTION 8
