2.    INVESTOR'S REPRESENTATIONS AND WARRANTIES.

      The Investor represents to the Company that:

      a.    Accredited Investor. The Investor is an 'accredited investor' as
that term is defined in Rule 501(a) of Regulation D. Investor has not been
organized for the purpose of investing in securities of the Company, although
such investment is consistent with its purposes.

      b.    Access to Information. The Investor has been granted the opportunity
to conduct a full and fair examination of the records, documents and files of
the Company, to ask questions of and receive answers from representatives of the
Company, its officers, directors, employees and agents concerning the terms and

obtain any additional information which the Investor deems necessary to verify
the accuracy of the information received. The Investor or its professional
advisor has received and reviewed the S-1 (as defined in Section 3.g).

      c.    Capability to Evaluate. The Investor is capable of evaluating the
merits and risks of the prospective investment. The Investor recognizes that
investment in the Shares involves certain risks, including the potential loss of
the Investor's investment therein, and the Investor understands all of the Risk
Factors (set forth in the S-1) related to the purchase of the Shares. The
Investor acknowledges that it has the ability to bear the economic risk of its
investment pursuant to this Agreement.

      d.    Illiquidity. The Investor is aware that there are legal and
practical limits on the Investor's ability to sell or dispose of the Shares,
and, therefore, that the Investor must bear the economic risk of the investment
for an indefinite period of time.


                                       3



      e.    Authority and Due. The Investor is duly and validly organized,
validly existing and in good tax and corporate standing as a corporation under
the laws of the jurisdiction of its incorporation with full power and authority
to purchase the Shares to be purchased by it and to execute and deliver this
Agreement.

      f.    Investment Purpose. The Investor is acquiring the Shares for its own
account for investment only and not with a present view towards the public sale
or distribution thereof, except pursuant to sales registered under the
Securities Act.

      g.    Reliance on Exemptions. The Investor understands that the Shares are
being offered and sold to it in reliance upon specific exemptions from the
registration requirements of United States federal and state securities laws and
that the Company is relying upon the truth and accuracy of, and the Investor's
compliance with, the representations, warranties, agreements, acknowledgments
and understandings of the Investor set forth herein in order to determine the
availability of such exemptions and the eligibility of the Investor to acquire
the Shares.

      h.    Transfer or Resale. The Investor understands that (i) the Shares
have not been and will not be registered under the Securities Act or any
applicable state securities laws, and may not be transferred unless (A)
subsequently registered thereunder, or (B) the Investor shall have delivered to
the Company an opinion of counsel (which counsel and opinion shall be reasonably
acceptable to the Company) to the effect that the Shares to be sold or
transferred may be sold or transferred pursuant to an exemption from such
registration or (C) sold pursuant to Rule 144 promulgated under the Securities
Act (or a successor rule); (ii) any sale of the Shares made in reliance on Rule
144 may be made only in accordance with the terms of said Rule and further, if
said Rule is not applicable, any resale of such Shares under circumstances in
which the seller (or the person through whom the sale is made) may be deemed to
be an underwriter (as that term is defined in the Securities Act) may require
compliance with some other exemption under the Securities Act or the rules and
regulations of the SEC thereunder; and (iii) neither the Company nor any other
person is under any obligation to register such Shares under the Securities Act
or any state securities laws or to comply with the terms and conditions of any
exemption thereunder.

      i.    Legends. The Investor understands that the certificates for the
Shares, until such time as they shall been registered under the Securities Act,
may bear a restrictive legend in substantially the following form (and a
stop-transfer order may be placed against transfer of the certificates for such
Shares):

      'The securities represented by this certificate have not been registered
      under the Securities Act of 1933, as amended. The securities have been
      acquired for investment and may not be sold, transferred or assigned in
      the absence of an effective registration statement for the securities
      under said Act, or an opinion of counsel, in form, substance and scope
      reasonably acceptable to the Company, that registration is not required
      under said Act or unless sold pursuant to Rule 144 under said Act.'

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of any Security upon which it is
stamped, if, unless otherwise required by applicable state securities laws, (a)
the sale of such Security is registered under the Securities Act, 


                                       4



or (b) such holder provides the Company with an opinion of counsel, in form,
substance and scope reasonably acceptable to the Company, to the effect that a
public sale or transfer of such Security may be made without registration under
the Securities Act or (c) such holder provides the Company with reasonable
assurances that such Security can be sold pursuant to Rule 144 under the
Securities Act (or a successor rule thereto) without any restriction as to the
number of Shares acquired as of a particular date that can then be immediately
sold. The Investor agrees that it will sell all Shares, including those
represented by a certificate(s) from which the legend has been removed, only in
compliance with all applicable securities laws.

become a default) under, or give to others any rights of termination, amendment

      p.    Material Agreements. Each agreement listed as an exhibit to the S-1
and each agreement entered into by the Company or its subsidiaries since the
filing of such S-1 that would have been 


                                       7



required to be included as an Exhibit to such S-1 had it been entered into on or
prior to such filing, is in full force and effect and is valid and enforceable
by the Company or one of its subsidiaries in accordance with its terms, except
where the failure of any such agreement to be in full force and effect and valid
and enforceable by the Company or one of its subsidiaries in accordance with its
terms would not have a material adverse effect on the assets or properties,
business, results of operations or financial condition of the Company and its
subsidiaries, taken as a whole, assuming the due authorization, execution and
delivery thereof by each of the other parties thereto. Neither the Company, nor
to the best of the Company's knowledge, any other party is in default in the
observance or performance of any term or obligation to be performed by it under
any such agreement, and no event has occurred which with notice or lapse of time
or both would constitute such a default which default or event would have a
material adverse effect on the assets or properties, business, results of
operations or financial condition of the Company and its subsidiaries, taken as
a whole. No default exists, and no event has occurred which with notice or lapse
of time or both would constitute a default, in the due performance and
observance of any term, covenant or condition, by the Company of any other
indenture, mortgage, deed of trust, note or any other agreement or instrument to
which the Company or any of its subsidiaries is a party or by which any of them
or their properties or businesses is bound or affected which default or event
would have a material adverse effect on the assets or properties, business,
results of operations or financial condition of the Company and its
subsidiaries, taken as a whole.

      q.    Compliance with Law. Each of the Company and its subsidiaries is
conducting its business in compliance with all applicable laws, rules and
regulations of the jurisdictions in which it is conducting business, including,
without limitation, all applicable local, state and federal environmental laws
and regulations, except where the failure to be so in compliance would not have
a material adverse effect on the assets or properties, business, results of
operations or financial condition of the Company and its subsidiaries, taken as
a whole.

      r.    Transactions with Affiliates. No transaction has occurred between or
among the Company and any of its officers or directors or any affiliate or
affiliates of any such officer or director that is required to be described in
and is not described in the S-1.

      s.    Insurance. Each of the Company and its subsidiaries maintains
liability, casualty and other insurance (subject to customary deductions and
retentions) with responsible insurance companies against such risk of the types
and in the amounts customarily maintained by internet advertising companies of
comparable size to the Company, all of which insurance is in full force and
effect.

      t.    Employment Matters. The Company and its subsidiaries are in
compliance with all federal, state, local and foreign laws and regulations
respecting employment and employment practices, terms and conditions of
employment and wages and hours. There are no pending investigations involving
the Company or any of its subsidiaries by the U.S. Department of Labor or any
other governmental agency responsible for the enforcement of such federal,
state, local or foreign laws and regulations. There is no unfair labor practice
charge or complaint against the Company or any of its subsidiaries pending
before the National Labor Relations Board or any strike, picketing, boycott,
dispute, slowdown or stoppage pending or threatened against or involving the
Company or any of its subsidiaries. No representation question exists respecting
the employees 


                                       8



of the Company or any of its subsidiaries, and no collective bargaining
agreement or modification thereof is currently being negotiated by the Company
or any of its subsidiaries. No grievance or arbitration proceeding is pending
under any expired or existing collective bargaining agreements of the Company or
any of its subsidiaries. No material labor dispute with the employees of the
Company or any of its subsidiaries exists or, to the knowledge of the Company,
is imminent.

      u.    ERISA Matters. None of the Company's employee benefit plans ('ERISA
Plans') subject to the Employee Retirement Income Security Act of 1974, as
amended ('ERISA') has engaged in a 'prohibited transaction' within the meaning
of Section 406 of ERISA or Section 4975 of the Internal Revenue Code of 1986, as
amended (the 'Code') which could subject the Company or any of its subsidiaries
to any tax penalty on prohibited transactions and which has not adequately been
corrected. No 'accumulated funding deficiency' (as defined in Section 302 of
ERISA) or any of the events set forth in Section 4043(b) of ERISA (other than
events with respect to which the 30-day notice under Section 4043 of ERISA has
been waived) has occurred with respect to any employee benefit plan which might
reasonably be expected to have a Material Adverse Effect. Each ERISA Plan is in
compliance with all material reporting, disclosure and other requirements of the
Code and ERISA as they relate to such ERISA Plan. Determination letters have
been received from the Internal Revenue Service with respect to each ERISA Plan
which is intended to comply with Code Section 401(a) stating that such ERISA
Plan and the attendant trust are qualified thereunder. Neither the Company nor
any of its subsidiaries has ever completely or partially withdrawn from a
'multi-employer plan' as so defined.

      v.    Investment Company Status. The Company is not an 'investment
company,' a company controlled by an 'investment company' or an 'affiliated
person' of, or 'promoter' or 'principal underwriter' for, an 'investment
company' as such terms are defined in the Investment Company Act of 1940, as
amended.

      w.    Environmental. Except as disclosed in the S-1, and except for
instances of noncompliance with or exceptions to the following that should not
have, individually or in the aggregate, a Material Adverse Effect, (i) the
Company and its operations are in full compliance with all environmental laws;
(ii) the Company is not aware of, nor has the Company received notice of, any
past, present, or future conditions, events, activities, practices, or incidents
which may interfere with or prevent the compliance or continued compliance of
the Company with all environmental laws; (iii) the Company has obtained all
permits, licenses, and authorizations that are required under applicable
environmental laws, and all such permits, licenses, and authorizations are in
good standing and the Company is in compliance with all of the terms and
conditions thereof; and (iv) no hazardous materials exist on, about, or within
or have been used, generated, stored, transported, disposed of on, or released
from any of the properties of the Company except in compliance with applicable
environmental laws. The Company is not subject to any outstanding or, to the
best of the Company's knowledge, threatened order from or agreement with any
governmental authority or other person or subject to any judicial or
administrative proceeding with respect to (A) failure to comply with
environmental laws, (B) remedial action, or (C) any environmental liabilities.

4.    COVENANTS OF THE INVESTOR.


                                       9
