statute, rule or regulation applicable to the Company. The execution,
delivery and performance of and compliance with the Agreements, and the
issuance of the Shares and the Common Stock issuable upon conversion of the
Shares, have not resulted and will not result in any material violation of,
or conflict with, or constitute a material default under, the Company's
Certificate of Incorporation or Bylaws or any of its agreements, nor result
in the creation of, any mortgage, pledge, lien, encumbrance or charge upon
any of the properties or assets of the Company.

authority on the part of the Company is required in connection with the valid
execution and delivery of the Agreements or the offer, sale or issuance of
the Shares, and the Common Stock issuable upon conversion of the Shares, or

may be necessary to secure an exemption from qualification, if available) of
the offer and sale of the Shares, and the Common Stock issuable upon

and qualifications, if required, will be accomplished in a timely manner.

         3.16    OFFERING. Subject to the accuracy of the each Purchaser's
representations in Section 4 hereof, the offer, sale and issuance of the
Shares to be issued in conformity with the terms of this Agreement, and the

5 of the Securities Act of 1933, as amended (the "SECURITIES ACT").

         3.17    BROKERS OR FINDERS. The Company has not engaged any brokers,
finders or agents, and the Purchasers have not incurred, and will not incur,
directly or indirectly, as a result of any action taken by the Company, any
liability for brokerage or finders' fees or agents' commissions or any
similar charges in connection with the Agreements. In the event that the
preceding sentence is in any way inaccurate, the Company hereby agrees to

commission or compensation in the nature of a finder's fee (and the costs and
expenses of defending against such liability or asserted liability) for which
such Purchaser or any of its officers, partners, employees or representatives
is responsible.

agreements with any of its employees. There is no labor union organizing
activity pending or, to the Company's knowledge, threatened with respect to
the Company. Except as set forth in the Schedule of Exceptions, the Company

deferred compensation arrangement, bonus plan, incentive plan, profit sharing
plan, retirement agreement or other employee compensation plan or agreement.
To the Company's knowledge, no employee of the Company, nor any consultant
with whom the Company has contracted, is in violation of any term of any
employment contract, proprietary information agreement or any other agreement

<PAGE>

right of any such individual to be employed by, or to contract with, the
Company because of the nature of the business to be conducted by the Company;
and to the Company's knowledge the continued employment by the Company of its
present employees, and the performance of the Company's contracts with its
independent contractors, will not result in any such violation. Neither Old
Participate nor the Company has received any notice alleging that any such
violation has occurred. No employee of the Company has been granted the right
to continued employment by the Company or to any material compensation
following termination of employment with the Company. The Company is not
aware that any officer or key employee, or that any group of key employees,
intends to terminate his, her or their employment with the Company, nor does
the Company have a present intention to terminate the employment of any
officer, key employee or group of key employees.

current and former employee, officer and consultant of Old Participate and
the Company has executed a Proprietary Information and Inventions Agreement
in the form previously provided to the Purchasers' special counsel. No
current or former employee, officer or consultant of Old Participate or the
Company has excluded works or inventions made prior to his or her employment
with Old Participate or the Company from his or her assignment of inventions
pursuant to such employee, officer or consultant's Proprietary Information
and Inventions Agreement.

         3.20    COMPLIANCE WITH LAWS; PERMITS. To the Company's knowledge,
neither Old Participate nor the Company is in violation of any applicable
statute, rule, regulation, order or restriction of any domestic or foreign
government or any instrumentality or agency thereof in respect of the conduct
of its business or the ownership of its properties which violation would
materially and adversely affect the business, assets, liabilities, financial
condition, operations or prospects of the Company. The Company has all
franchises, permits, licenses and any similar authority necessary for the
conduct of its business as now being conducted by it, the lack of which could
materially and adversely affect the business, properties, prospects or
financial condition of the Company, and believes it can obtain, without undue
burden or expense, any similar authority for the conduct of its business as
planned to be conducted.

         3.21    ENVIRONMENTAL AND SAFETY LAWS. To the best of its knowledge,
the Company is not in violation of any applicable statute, law, or regulation
relating to the environment or occupational health and safety, and to the
best of its knowledge, no material expenditures are or will be required in
order to comply with any such existing statute, law or regulation.

         3.22    OBLIGATIONS TO RELATED PARTIES. There are no obligations of
the Company to officers, directors, stockholders, members or employees of the
Company or Old Participate other than (a) for payment of salary for services
rendered, (b) reimbursement for reasonable expenses incurred on behalf of the
Company or Old Participate and (c) for other standard employee benefits made
generally available to all employees (including stock option agreements
outstanding under any stock option plan approved by the Board of Directors of
the Company). To the best of the Company's knowledge, no officer, director or
stockholder, member or any member of their immediate families, is, directly
or indirectly, interested in any material contract with Old Participate

                                       -8-

<PAGE>

or the Company (other than such contracts as relate to any such person's
ownership of capital stock or other securities of the Company). Neither the
Company nor Old Participate is a guarantor or indemnitor of any indebtedness
of any other person, firm or corporation.

         3.23 TAX RETURNS AND PAYMENTS. Old Participate and the Company have
timely filed all tax returns (federal, state and local) required to be filed by
them. All taxes shown to be due and payable on such returns, any assessments
imposed, and to the Company's knowledge, all other taxes due and payable by Old
Participate or the Company on or before the Closing, have been paid, or will be
paid, prior to the time they become delinquent. Neither Old Participate nor the
Company have been advised (a) that any of their returns, federal, state or
other, have been or are being audited as of the date hereof or (b) of any
deficiency in assessment or proposed judgment to its federal, state or other
taxes. The Company has no knowledge of any liability of any tax to be imposed
upon its properties or assets as of the date of this Agreement that is not
adequately provided for.

         3.24 QUALIFIED SMALL BUSINESS. To the Company's knowledge, the Company
is a "qualified small business" within the meaning of Section 1202(d) of the
Internal Revenue Code of 1986, as amended (the "Code"), as of the date hereof
and the Shares should qualify as "qualified small business stock" as defined in
Section 1202(c) of the Code as of the date hereof. The Company further
represents and warrants that, as of the date hereof, it meets the "active
business requirement" of Section 1202(e) of the Code, and it has made no
"significant redemptions" within the meaning of Section 1202(c)(3)(B) of the
Code.

         3.25 MINUTE BOOKS. The minute books of Old Participate and the Company
made available to the Purchasers contain a complete summary of all actions and
meetings of directors and stockholders since the time of incorporation.

         3.26 INSURANCE. The Company has fire and casualty insurance policies
with coverage customary for companies similarly situated to the Company.

         3.27 CONSOLIDATION OF OLD PARTICIPATE. The Company and Old Participate
have agreed to the roll-up of Old Participate into the Company and the
dissolution of Old Participate (the "Roll-Up") and the Roll-Up has been
consummated. The documents and agreements entered into by the Company and Old
Participate in connection with the Roll-Up (the "Roll-Up Agreements") are in
substantially the same form as have been provided to the Purchasers prior to the
Closing. Pursuant to the Roll-Up, the Company has acquired good and marketable
title to all properties, assets and leasehold estates purported to be
transferred pursuant to the Roll-Up Documents and the Roll-Up Documents are
valid and binding obligations of the parties thereto, enforceable in accordance
with their terms.

                                    SECTION 4

                REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

         Each Purchaser hereby severally represents and warrants to the Company
with respect to the purchase of Shares by such Purchaser, and with respect only
to such Purchaser, as follows:

                                    - 9 -
<PAGE>

         4.1 EXPERIENCE; SPECULATIVE NATURE OF INVESTMENT. The Purchaser has
substantial experience in evaluating and investing in private placement
transactions of securities in companies similar to the Company so that it is
capable of evaluating the merits and risks of its investment in the Company and
has the capacity to protect its own interests. The Purchaser acknowledges that
its investment in the Company is highly speculative and entails a substantial
degree of risk and the Purchaser is in a position to lose the entire amount of
such investment.

         4.2 INVESTMENT. The Purchaser is acquiring the Shares and the
underlying Common Stock 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. The Purchaser understands that the Series B Preferred to
be purchased hereby and the underlying Common Stock have 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 investment intent
and the accuracy of the Purchaser's representations as expressed herein. The
Purchaser is an "accredited investor" within the meaning of Regulation D, Rule
501(a), promulgated by the Securities and Exchange Commission.

         4.3 RULE 144. The Purchaser acknowledges that the Shares and the
underlying Common Stock must be held indefinitely unless subsequently registered
under the Securities Act or unless an exemption from such registration is
available. The 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 transactions directly with a "market maker" and the number of shares being
sold during any three-month period not exceeding specified limitations.

         4.4 NO PUBLIC MARKET. The 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.

         4.5 ACCESS TO DATA. The Purchaser has had an opportunity to discuss the
Company's business, management and financial affairs with its management. The
Purchaser has also had an opportunity to ask questions of officers of the
Company, which questions were answered to its satisfaction. The Purchaser
understands that such discussions, as well as any written information issued by
the Company, were intended to describe certain aspects of the Company's business
and prospects but were not a thorough or exhaustive description.

         4.6 AUTHORIZATION. The Agreements, when executed and delivered by the
Purchaser, will constitute valid and legally binding obligations of the
Purchaser, enforceable in accordance with their terms, except as the
indemnification provisions of Section 1.10 of the Rights Agreement may be
limited by principles of public policy, and 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.

                                    - 10 -
<PAGE>

         4.7 BROKERS OR FINDERS. The Purchaser has not engaged any brokers,
finders or agents, and the Company has not, and will not, incur, directly or
indirectly, as a result of any action taken by the Purchaser, any liability for
brokerage or finders' fees or agents' commissions or any similar charges in
connection with the Agreements. In the event that the preceding sentence is in
any way inaccurate, such Purchaser agrees to indemnify and hold harmless the
Company and each other Purchaser from any liability for any commission or
compensation in the nature of a finder's fee (and the costs and expenses of
defending against such liability) for which the Company, any other Purchaser, or
any of their officers, directors, employees or representatives, is responsible.

         4.8 TAX LIABILITY. The Purchaser has reviewed with its own tax advisors
the federal, state, local and foreign tax consequences of this investment and
the transactions contemplated by the Agreements. With respect to such matters,
the Purchaser relies solely on such advisors and not on any statements or
representations of the Company or any of its agents other than the
representations and warranties set forth herein. The Purchaser understands that
it (and not the Company) shall be responsible for its own tax liability that may
arise as a result of this investment or the transactions contemplated by the
Agreements.

                                    SECTION 5

Re:      Management Rights

Dear Sirs:

You have informed us that pursuant to regulations promulgated by the U.S.
Department of Labor, you are required to receive "management rights" in
connection with portfolio investments that you make. This letter will confirm
our agreement that pursuant to the purchase of Series B Preferred Stock of
Participate.com, Inc. (the "Company") by InterWest Partners VII, L.P.
("Investor"), Investor will be entitled to the following contractual management
rights, in addition to rights to nonpublic financial information, inspection
rights, and other rights specifically provided to all investors in the current
financing:

         (1) Investor shall be entitled to consult with and advise management of
the Company on significant business issues, including management's proposed
annual operating plans, and management will meet with Investor regularly during
each year at the Company's facilities at mutually agreeable times for such
consultation and advice and to review progress in achieving said plans;

         (2) Investor may examine the books and records of the Company and
inspect its facilities and may request information at reasonable times and
intervals concerning the general status of the Company's financial condition and
operations, provided that access to highly confidential proprietary information
and facilities need not be provided; and

         (3) If Investor is not represented on this Company's Board of
Directors, the Company shall invite a representative of Investor to attend all
meetings of its Board of Directors in a nonvoting observer capacity and, in this
respect, shall give such representative copies of all notices, minutes,
consents, and other material that it provides to its directors; provided,
however, that the Company reserves the right to exclude such representative from
access to any material or meeting or portion thereof if the Company believes
upon advice of counsel that such exclusion is reasonably necessary to preserve
the attorney-client privilege, to protect highly confidential proprietary
information or for other similar reasons. Such representative may participate in
discussions of matters brought to the Board of Directors.

                                      G-1
<PAGE>

Investor agrees, and any representative of Investor will agree, to hold in
confidence and trust and not use or disclose any confidential information
provided to or learned by it in connection with its rights under this letter.

The rights described herein shall terminate and be of no further force or effect
(i) upon the consummation of the sale of the Company's securities pursuant to a
registration statement filed by the Company under the Securities Act of 1933, as
amended in connection with the firm commitment underwritten offering of its
securities to the general public, or (ii) at such time as the Investor and any
affiliates hold less than ten percent (10%) of the outstanding Series B
Preferred Stock of the Company. The confidentiality provision hereof will
survive any such termination.

Very truly yours,

representations in Section 4 hereof, the offer, sale and issuance of the Shares
to be issued in conformity with the terms of this Agreement, and the issuance of

Securities Act of 1933, as amended (the "SECURITIES ACT").

         3.17 BROKERS OR FINDERS. The Company has not engaged any brokers,

has contracted, is in violation of any term of any employment contract,
proprietary information agreement or any other agreement relating to the right
of any such individual to be employed by, or to contract with, the Company
because of the nature of the business to be conducted by the Company; and to the
Company's knowledge the continued employment by the Company of its present
employees, and the performance of the Company's contracts with its independent
contractors, will not result in any such violation. Neither Old Participate nor
the Company has received any notice alleging that any such violation has
occurred. No employee of the Company has been granted the right to continued
employment by the Company or to any material compensation following termination

Old Participate nor the Company is in violation of any applicable statute, rule,
regulation, order or restriction of any domestic or foreign government or any
instrumentality or agency thereof in respect of the conduct of its business or
the ownership of its properties which violation would materially and adversely
affect the business, assets, liabilities, financial condition, operations or
prospects of the Company. The Company has all franchises, permits, licenses and
any similar authority necessary for the conduct of its business as now being
conducted by it, the lack of which could materially and adversely affect the
business, properties, prospects or financial condition of the Company, and
believes it can obtain, without undue burden or expense, any similar authority
for the conduct of its business as planned to be conducted.

them. All taxes shown to be due and payable on such returns, any assessments

Company have been advised (a) that any of their returns, federal, state or
other, have been or are being audited as of the date hereof or (b) of any
deficiency in assessment or proposed judgment to its federal, state or other
taxes. The Company has no knowledge of any liability of any tax to be imposed

                                   SECTION 4

                REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

         Each Purchaser hereby severally represents and warrants to the Company
with respect to the purchase of Shares by such Purchaser, and with respect only
to such Purchaser, as follows:

         4.1 EXPERIENCE; SPECULATIVE NATURE OF INVESTMENT. The Purchaser has
substantial experience in evaluating and investing in private placement
transactions of securities in companies similar to the Company so that it is
capable of evaluating the merits and risks of its investment in the Company and
has the capacity to protect its own interests. The Purchaser acknowledges that
its

                                     - 9 -
<PAGE>

investment in the Company is highly speculative and entails a substantial
degree of risk and the Purchaser is in a position to lose the entire amount of
such investment.

         4.2 INVESTMENT. The Purchaser is acquiring the Shares and the
underlying Common Stock 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. The Purchaser understands that the Shares and the
underlying Common Stock have 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 investment intent and the accuracy of
the Purchaser's representations as expressed herein. The Purchaser is an
"accredited investor" within the meaning of Regulation D, Rule 501(a),
promulgated by the Securities and Exchange Commission.

         4.3 RULE 144. The Purchaser acknowledges that the Shares and the
underlying Common Stock must be held indefinitely unless subsequently registered
under the Securities Act or unless an exemption from such registration is
available. The 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 transactions directly with a "market maker" and the number of shares being
sold during any three-month period not exceeding specified limitations.

         4.4 NO PUBLIC MARKET. The 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.

         4.5 ACCESS TO DATA. The Purchaser has had an opportunity to discuss the
Company's business, management and financial affairs with its management. The
Purchaser has also had an opportunity to ask questions of officers of the
Company, which questions were answered to its satisfaction. The Purchaser
understands that such discussions, as well as any written information issued by
the Company, were intended to describe certain aspects of the Company's business
and prospects but were not a thorough or exhaustive description.

         4.6 AUTHORIZATION. The Agreements, when executed and delivered by the
Purchaser, will constitute valid and legally binding obligations of the
Purchaser, enforceable in accordance with their terms, except as the
indemnification provisions of Section 1.10 of the Stockholder Rights Agreement
may be limited by principles of public policy, and 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.

         4.7 BROKERS OR FINDERS. The Purchaser has not engaged any brokers,
finders or agents, and the Company has not, and will not, incur, directly or
indirectly, as a result of any action taken by the Purchaser, any liability for
brokerage or finders' fees or agents' commissions or any similar charges

                                     - 10 -

in connection with the Agreements. In the event that the preceding sentence is
in any way inaccurate, such Purchaser agrees to indemnify and hold harmless the
Company and each other Purchaser from any liability for any commission or
compensation in the nature of a finder's fee (and the costs and expenses of
defending against such liability) for which the Company, any other Purchaser, or
any of their officers, directors, employees or representatives, is responsible.

         4.8 TAX LIABILITY. The Purchaser has reviewed with its own tax advisors
the federal, state, local and foreign tax consequences of this investment and
the transactions contemplated by the Agreements. With respect to such matters,
the Purchaser relies solely on such advisors and not on any statements or
representations of the Company or any of its agents other than the
representations and warranties set forth herein. The Purchaser understands that
it (and not the Company) shall be responsible for its own tax liability that may
arise as a result of this investment or the transactions contemplated by the
Agreements.

provisions hereof shall inure to the benefit of, and be binding upon, the
successors, assigns, heirs, executors and administrators of the parties hereto;

         7.5 ENTIRE AGREEMENT; AMENDMENT. This Agreement and the other documents
delivered pursuant hereto at each Closing constitute the full and entire
