     WHEREAS, the Purchasers, severally, wish to purchase the Preferred Shares
on the terms and subject to the conditions set forth in this Agreement;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained in this Agreement, the parties agree as follows:

          (a) The Company is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of Delaware and is duly
qualified to transact business as a foreign corporation and is in good standing
in each jurisdiction in which the nature of the business transacted by it or the
character of the properties owned or leased by it requires such qualification
except where failure to so qualify could not reasonably be expected to result in
a material adverse effect on the Company or its business. The Company has the
corporate power and authority to own and hold its properties and to carry on its
business as now conducted, to execute, deliver and perform this Agreement, the
Amended and Restated Registration Rights Agreement with the Purchasers and the
other parties thereto in the form attached as Exhibit A (the "Registration
                                              ---------
Rights Agreement") and the Amended and Restated Stockholders Agreement with the
Purchasers and the other parties thereto in the form attached as Exhibit B (the
                                                                 ---------
"Stockholders Agreement"), to issue, sell and deliver the Preferred Shares and
to issue and deliver the shares of Series A Common Stock, $.00l par value, of
the Company issuable upon conversion of the Preferred Shares (the "Conversion
Shares").

          (b) The Company has one subsidiary, Talkpoint Communications, Inc., a
Delaware corporation ("Talkpoint"). Except for Talkpoint, the Company does not
(i) own of record or beneficially, directly or indirectly, (A) any shares of
capital stock or securities convertible into capital stock of any other
corporation or (B) any participating interest in any partnership, joint venture
or other non-corporate business enterprise or (ii) control, directly or
indirectly, any other entity.

     Section 2.02 Authorization of Agreements; Etc.
     ---------------------------------------------

          (a) The execution and delivery by the Company of this Agreement, the
Registration Rights Agreement and the Stockholders Agreement, the performance by
the Company of its obligations hereunder and thereunder, the issuance, sale and
delivery of the Preferred Shares and the issuance and delivery of the Conversion
Shares have been duly authorized by all requisite corporate action and will not
violate any provision of law, any order of any court or other agency of
government, the Second Amended and Restated Certificate of Incorporation of the
Company, as amended (the "Charter"), or the By-laws of the Company, as amended,
or any provision of any indenture, agreement or other instrument to which the
Company, any of its subsidiaries or any of their respective properties or assets
is bound, or conflict with, result in a breach of or constitute (with due notice
or lapse of time or both) a default under any such indenture, agreement or other
instrument, or result in the creation or imposition of any lien, charge,
restriction, claim or encumbrance of any nature whatsoever upon any of the
properties or assets of the Company or any of its subsidiaries.

          (b) The Preferred Shares have been duly authorized and, when issued in
accordance with this Agreement, will be validly issued, fully paid and
nonassessable shares with no personal liability attaching to the ownership
thereof and will be free and clear of all liens, charges, restrictions, claims
and encumbrances imposed by or through the Company except as set forth in the
Registration Rights Agreement. The Conversion Shares have been duly reserved

                                       2
<PAGE>

for issuance upon conversion of the Preferred Shares and, when so issued, will
be duly authorized, validly issued, fully paid and nonassessable shares of
Common Stock with no personal liability attaching to the ownership thereof and
will be free and clear of all liens, charges, restrictions, claims and
encumbrances imposed by or through the Company except as set forth in the
Registration Rights Agreement. Neither the issuance, sale or delivery of the
Preferred Shares nor the issuance or delivery of the Conversion Shares is
subject to any preemptive right of stockholders of the Company or to any right
of first refusal or other right in favor of any person, other than the rights of
Thomson as set forth in that certain Amended and Restated Agreement Among
Thomson and Founders dated as of March 31, 1999, by and among Thomson, the
Company, the Parker Family Limited Partnership, Jeffrey P. Parker and Robert I.
Adler (the "Thomson Agreement") and the rights of certain major holders of the
Company's Series D Preferred Stock (the "Major Purchasers") pursuant to the
Series D Convertible Preferred Stock Purchase Agreement dated June 9, 1999 by
and among the Company and the several purchasers named therein (the "Series D
Purchase Agreement"). Thomson's preemptive right with respect to the Preferred
Shares issued to AOL hereunder are reflected in the total number of Preferred
Shares Thomson is purchasing hereunder. Each Major Purchaser has waived its
preemptive rights with respect to the issuance and sale of the Preferred Shares.
In addition to the Preferred Shares being issued pursuant to this Agreement, the
Company has reserved 250,000 additional shares of its Series E-1 Preferred Stock
to be issued to AOL upon exercise of AOL's right to purchase such shares
pursuant to a Stock Subscription Warrant between the Company and AOL of even
date herewith (the "Warrant Agreement").

     Section 2.03 Validity. This Agreement has been duly executed and delivered
                  --------
by the Company and constitutes the legal, valid and binding obligation of the
Company, enforceable in accordance with its terms, and the Registration Rights
Agreement and the Stockholders Agreement, when executed and delivered in
accordance with this Agreement, will constitute the legal, valid and binding
obligations of the Company, enforceable in accordance with their respective
terms, in each case, except insofar as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, or similar laws
of general application affecting enforcement of creditors' rights and except as
to enforceability of the indemnification and contribution provisions of the
Registration Rights Agreement.

all necessary United States permits, licenses and other authorizations required
to conduct its business as conducted, and the Company has been operating its
business pursuant to and in compliance with the terms of all such permits,
licenses and other authorizations except where the failure to obtain such

conditions of his employment, non-competition or non-disclosure agreement with
such third party, (b) disclosed or may be disclosing or utilized or may be
utilizing any trade secret or proprietary information or documentation of such
third party or (c) interfered or may be interfering in the employment
relationship between such third party and any of its present or former

suggests that such a claim might be contemplated. To the Company's knowledge, no
person employed by or affiliated with the Company has employed or proposes to
employ any trade secret or any information or documentation proprietary to any
former employer, and to the Company's knowledge, no person employed by or
affiliated with the Company has violated any confidential relationship which
such person may have had with any third party, in connection with the
development or sale of any product or proposed product or the development or
sale of any service or proposed service of the Company, and the Company has no
reason to believe there will be any such employment or violation. To the
Company's knowledge, none of the execution or delivery of this Agreement, or the
carrying on of the business of the Company as officers, employees or agents by
any officer, director or key employee of the Company, or the conduct or proposed
conduct of the business of the Company, will conflict with or result in a breach
of the terms, conditions or provisions of or constitute a default under any
contract, covenant or instrument under which any such person is obligated.

applications, trademarks, trademark applications, service marks, service mark

are in the process of being prepared, owned by or registered in the name of the
Company, or of which the Company is a licensor or licensee or in which the
Company has any rights other than generally commercially available third-party
software. The Company owns or possesses adequate licenses or other rights to
use, or to its knowledge can develop or has developed, all patents, patent
applications, trademarks, trademark applications, service marks, service mark
applications, trade names, copyrights, manufacturing processes,

                                       6
<PAGE>

formulae, trade secrets, customer lists and know how (collectively,
"Intellectual Property") material to the conduct of its business as conducted,
and no claim is pending or, to the Company's knowledge, threatened to the effect
that the operations of the Company infringe upon or conflict with the asserted
rights of any other person under any Intellectual Property, and to the Company's
knowledge there is no basis for any such claim (whether or not pending or
threatened). No claim is pending or, to the Company's knowledge threatened, to
the effect that any such Intellectual Property owned or licensed by the Company,
or which the Company otherwise has the right to use, is invalid or unenforceable
by the Company, and, to the Company's knowledge, there is no basis for any such
claim (whether or not pending or threatened). To the Company's knowledge, all
technical information developed by and belonging to the Company which has not
been patented has been kept confidential.

     Section 2.10   Title to Properties. The Company has good, clear and
                    -------------------
marketable title to its properties and assets reflected on the Balance Sheet or
acquired by them since the date of the Balance Sheet (other than properties and
assets disposed of in the ordinary course of business since the date of the
Balance Sheet), and all such properties and assets are free and clear of
mortgages, pledges, security interests, liens, charges, claims, restrictions and
other encumbrances (including without limitation, easements and licenses),
except for liens for or current taxes not yet due and payable and minor
imperfections of title, if any, not material in nature or amount and not
materially detracting from the value or impairing the use of the property
subject thereto or impairing the operations or proposed operations of the
Company and its subsidiaries. To the Company's knowledge after due inquiry,
there are no condemnation, environmental, zoning or other land use regulation
proceedings, either instituted or planned to be instituted, which would
adversely affect the use or operation of the Company's properties and assets for
their intended uses and purposes, or the value of such properties, and the
Company has not received notice of any special assessment proceedings which
would affect such properties and assets.

     Section 2.11   Leasehold Interests. Each lease or agreement to which the
                    -------------------
Company is a party under which it is a lessee of any property, real or personal,
is a valid and subsisting agreement, duly authorized and entered into, without
any default of the Company thereunder and, to the Company's knowledge, without
any default thereunder of any other party thereto. No event has occurred and is
continuing which, with due notice or lapse of time or both, would constitute a
default or event of default by the Company under any such lease or agreement or,
to the Company's knowledge, by any other party thereto. The Company's possession
of such property has not been disturbed and, to the Company's knowledge after
due inquiry, no claim has been asserted against the Company adverse to its
rights in such leasehold interests.

                    -----
state, county and local, required to be filed by it, and the Company has paid
all taxes shown to be due on such returns. The Company has established reserves
for all taxes accrued but not yet payable in accordance with generally accepted
accounting principles. The Federal income tax returns of the Company have never
been audited by the Internal Revenue Service. No deficiency assessment with
respect to or proposed adjustment of the Company's Federal state, county or
local taxes is

                                       7
<PAGE>

pending or, to the Company's knowledge, threatened. There is no tax lien,
whether imposed by any Federal, state, county or local taxing authority,
outstanding against the assets, properties or business of the Company. Neither
the Company nor any of its present or former stockholders has ever filed an
election pursuant to Section 1362 of the Internal Revenue Code of 1986, as
amended (the "Code"), that the Company be taxed as an S corporation.

     The Company, and to the Company's knowledge after due inquiry, each other

          Article IV. CONDITIONS TO THE OBLIGATIONS OF THE PURCHASERS

     The obligation of each Purchaser to purchase and pay for the Preferred
Shares being purchased by it on the Closing Date is, at its option, subject to
the satisfaction, on or before the Closing Date, of the following conditions:

          (a)  Opinion of Company's Counsel. The Purchasers shall have received
               ---------- -----------------
from Foley, Hoag & Eliot LLP, counsel for the Company, an opinion dated the
Closing Date, in form and scope satisfactory to the Purchasers and their
counsel, substantially to the effect that:

               (i)   The Company is a corporation duly incorporated, validly
existing and in good standing under the laws of the State of Delaware. The
Company is duly qualified to transact business as a foreign corporation and is
in good standing in Massachusetts and California. The Company has the corporate
power and authority to own and hold its properties and to carry on its business
as currently conducted. The Company has the corporate power and authority to

and the Stockholders Agreement, to issue, sell and deliver the Preferred Shares
and, upon conversion thereof, to issue and deliver the Conversion Shares.

               (ii)  This Agreement, the Registration Rights Agreement, the
Stockholders Agreement and the Warrant Agreement have been duly authorized,
executed and delivered by the Company and constitute the legal, valid and
binding obligations of the Company, enforceable in accordance with their
respective terms (subject, as to enforcement of remedies, to the discretion of
courts in awarding equitable relief and to applicable bankruptcy,
reorganization, insolvency, moratorium and similar laws affecting the rights of
creditors generally), except that such counsel need not express any opinion as
to the validity or enforceability of the indemnification and contribution
provisions of the Registration Rights Agreement.

               (iii) The execution and delivery by the Company of this
Agreement, the Registration Rights Agreement and the Stockholders Agreement, the
performance by the Company of its obligations hereunder and thereunder, the

thereof, the issuance and delivery of the Conversion Shares, will not violate
any provision of law, the Charter or By-laws, as amended, of the Company, any
order of any court or other agency of government or any indenture, agreement or
other instrument known to such counsel to which the Company, or any of its
properties or assets is bound, or conflict with, result in a breach of or
constitute (with due notice or lapse of time or both) a default under any such
indenture, agreement or other instrument, or result in the creation or
imposition of any lien, charge, restriction, claim or encumbrance of any nature
whatsoever upon any of the properties or assets of the Company. In rendering the
foregoing opinion, such counsel may assume full disclosure to the Purchasers of
all material facts and, with respect to performance by the Company of its
obligations under the Registration Rights Agreement may assume compliance by the
Company at such time with the registration requirements of the Securities Act
and with applicable state securities laws and may disclaim any opinion as to the

                                       15
<PAGE>

validity or enforceability of the indemnification and contribution provisions of
the Registration Rights Agreement.

     share; and
     709,970 shares of Series D Convertible Preferred Stock par value $.01 per
     share.

Immediately prior to the Closing, the stockholders of record and holders of
record of subscriptions, warrants, options, convertible securities, and other
rights (contingent or other) to purchase or otherwise acquire equity securities
of the Company, and the number of shares of Common Stock or Preferred Stock and
the number of such subscriptions, warrants, options, convertible securities, and
other such rights held by each, will be as set forth in Schedule IV. For
purposes of the foregoing opinion, counsel may rely on the records in its
possession. The designations, powers, preferences, rights, qualifications,
limitations and restrictions in respect of each class or series of authorized
capital stock of the Company are as set forth in the Charter and all such
designations, powers, preferences, rights, qualifications, limitations and
restrictions are valid, binding and enforceable and in accordance with all
applicable laws (subject, as to enforcement, to the discretion of courts in
awarding equitable relief and to applicable bankruptcy, reorganization,
insolvency, moratorium and similar laws affecting the rights of

                                       16
<PAGE>

creditors generally). Except as set forth in Schedule IV, to the knowledge of
such counsel, immediately prior to the Closing no subscription, warrant, option,
convertible security, or other right (contingent or other) to purchase or
acquire equity securities of the Company shall be authorized or outstanding and
there will be no commitment by the Company to issue shares, subscriptions,
warrants, options, convertible securities, or other such rights or to distribute
to holders of any of its equity securities any evidence of indebtedness or
asset. Except as set forth in Schedule IV or as provided for in the Charter, to
the knowledge of such counsel the Company has no obligation (contingent or
other) to purchase, redeem or otherwise acquire any of its equity securities or
any interest therein or to pay any dividend or make any other distribution in
respect thereof.

          (v)   The Preferred Shares and the Conversion Shares have been duly
authorized. The issuance, sale and delivery of the Preferred Shares and the
issuance and delivery of the Conversion Shares upon conversion of the Preferred
Shares have been duly authorized by all required corporate action; the Preferred
Shares have been validly issued, are fully paid and nonassessable and, to the
knowledge of such counsel, are free and clear of all liens, charges,
restrictions, claims and encumbrances imposed by or through the Company except
as set forth in the Registration Rights Agreement; and the Conversion Shares
have been duly reserved for issuance upon conversion of the Preferred Shares
and, when so issued, will be validly issued, fully paid and nonassessable and,
to the knowledge of such counsel, will be free and clear of all liens, charges,
restrictions, claims and encumbrances imposed by or through the Company except
as set forth in the Registration Rights Agreement. Neither the issuance, sale or
delivery of the Preferred Shares nor the issuance or delivery of the Conversion
Shares is subject to any preemptive right of stockholders of the Company arising
under law or the Charter or By-laws of the Company, each as amended, which has
not been waived, or, to the knowledge of such counsel, to any contractual right
of first refusal or other right in favor of any person, other than the rights
set forth in the Thomson Agreement.

          (vi)  Assuming that the Company's Board of Directors has duly
authorized the Company to file a Certificate of Designation setting the price of
the Warrant Shares each time such shares are to be issued, and that such a
Certificate of Designation has been filed, if issued against payment therefor in
accordance with the Warrant Agreement, such Warrant Shares will be validly
issued, fully paid and nonassessable, and, to the knowledge of such counsel,
will be free and clear of all liens, charges, restrictions, claims and
encumbrances imposed by or through the Company except as set forth in the
Registration Rights Agreement. The issuance, sale or delivery of the such shares
is not subject to any preemptive right of stockholders of the Company arising
under law or the Charter or By-laws of the Company, each as amended, which has
not been waived, or, to the knowledge of such counsel, to any contractual right
of first refusal or other right in favor of any person, other than the rights
set forth in the Thomson Agreement.

          (vii) To the knowledge of such counsel there is no (A) action, suit
proceeding or investigation pending or threatened against the Company, at law or
in equity, or before or by any Federal, state, municipal or other governmental
department, commission, board, bureau, agency or instrumentality, domestic or
foreign, (B) arbitration proceeding relating to the Company pending under
collective bargaining agreements or (C) governmental inquiry pending

                                  17
<PAGE>

or threatened against the Company (including, without limitation, any inquiry as
to the clarification of the Company to hold or receive any license or permit).
To the knowledge of such counsel, the Company is not in default with respect to
any order, writ, injunction or decree known to such counsel of any court or of
any Federal, state, municipal or other governmental department, commission,
board, bureau, agency or instrumentality, domestic or foreign.

               (viii) Assuming the accuracy of the representations and
warranties of the Purchasers set forth in Article III, no registration or filing
with, and no consent or approval of, or other action by any Federal, state or
other governmental agency or instrumentality is or will be necessary under
current law for the valid execution, delivery and performance by the Company of
this Agreement, the issuance, sale and delivery of the Preferred Shares or, upon
conversion thereof, the issuance and delivery of the Conversion Shares, other
than filings pursuant to state securities laws (all of which filings, other than
those which are required to be made after the Closing, have been made by the
Company). In rendering the foregoing opinion with respect to performance by the
Company of its obligations under the Registration Rights Agreement, such counsel
may assume compliance by the Company at such time with the registration
requirements of the Securities Act and with applicable state securities laws and
may disclaim any opinion as to the validity of enforceability of the
indemnification and contribution provision of the Registration Rights Agreement.

               (ix)   All of the outstanding shares of capital stock have been
issued in compliance with the registration requirements of the Securities Act
and all applicable state securities laws.

          (b)  Representations and Warranties to be True and Correct. The
               -----------------------------------------------------

                  ----------------------
proposed issuance by the Company of any of its securities (other than debt
securities with no equity feature), offer to AOL under this Agreement by written
notice the right, for a period of twenty (20) days, to purchase for cash at an
amount equal to the price or other consideration for which such securities are
to be issued, a number of such securities so that, after giving effect to such
issuance (and the conversion, exercise and exchange into or for (whether
directly or indirectly) shares of Common Stock of all such securities that are
so convertible, exercisable or exchangeable), AOL will continue to maintain its
same proportionate equity ownership in the Company as of the date of such notice
(treating AOL, for the purpose of such computation, as the holder of the number
of shares of Common Stock which would be issuable to AOL upon conversion,
exercise and exchange of all securities (including but not limited to the
Preferred Shares) held by AOL on the date such offer is made, that are
convertible, exercisable or exchangeable into or for (whether directly or
indirectly) shares of Common Stock and assuming the like conversion, exercise
and exchange of all such other securities held by other persons), but excluding
shares of Common Stock issuable to AOL upon its exercise of any right to
purchase Common Stock pursuant to the Warrant issued to AOL by the Company in
connection with the Interactive Services Agreement; provided, however, that the
participation rights of AOL pursuant to this Section 6.2 shall not apply to
securities issued (A) upon conversion of any of the Preferred Shares or Common
Shares, (B) as a stock dividend or upon any subdivision of shares of Common
Stock, provided that the securities issued pursuant to such stock dividend or
subdivision are limited to additional shares

                                       21
<PAGE>

of Common Stock, (C) pursuant to subscriptions, warrants, options, convertible
securities, or other rights which are listed in Schedule IV as being outstanding
on the date of this Agreement, (D) solely in consideration for the acquisition
(whether by merger or otherwise) by the Company or any of its subsidiaries of
all or substantially all of the stock or assets of any other entity, (E)
pursuant to a firm commitment public offering, (F) pursuant to the exercise of
options to purchase Common Stock, or as direct stock grants, not to exceed
twenty-five percent (25%) of the Company's outstanding shares of capital stock
on a fully diluted basis, that were granted by the Board of Directors and
approved by the Compensation Committee (as defined in Section 6.19) under any
Company stock option plan to directors, officers, employees or consultants of
the Company in connection with their service to the Company (the shares exempted
by this clause (F) being hereinafter referred to as the "Reserved Employee
Shares"), and (G) pursuant to the exercise by Thomson of its preemptive rights
to purchase securities described in Subsections (D) or (F) above under the
Thomson Agreement. The Company's written notice to AOL shall describe the

and payment terms. AOL may accept the Company's offer as to the full number of
securities offered to it or any lesser number, by written notice thereof given
by it to the Company prior to the expiration of the aforesaid twenty (20) day
period, in which event the Company shall promptly sell and AOL shall buy, upon
the terms specified, the number of securities agreed to be purchased by AOL. The
Company shall be free at any time prior to one hundred twenty (120) days after
the date of its notice of offer to AOL, to offer and sell to any third party or
parties the remainder of such securities proposed to be issued by the Company
(including but not limited to the securities not agreed by AOL to be purchased
by it), at a price and on payment terms no less favorable to the Company than
those specified in such notice of offer to AOL. However, if such third party
sale or sales are not consummated within such one hundred twenty (120) day
period, the Company shall not sell such securities as shall not have been
purchased within such period without again complying with this Section 6.2.

     Section 6.03 Reserve for Conversion Shares. The Company shall at all times
                  -----------------------------
reserve and keep available out of its authorized but unissued shares of Common
Stock, for the purpose of effecting the conversion of the Preferred Shares and
otherwise complying with the terms of this Agreement, such number of its duly
authorized shares of Common Stock as shall be sufficient to effect the
conversion of the Preferred Shares from time to time outstanding or otherwise to
comply with the terms of this Agreement. If at any time the number of authorized
but unissued shares of Common Stock shall not be sufficient to effect the
conversion of the Preferred Shares or otherwise to comply with the terms of this
Agreement, the Company will forthwith use its best efforts to take such
corporate action as may be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purposes. The Company will obtain any authorization, consent, approval or other
action by or make any filing with any court or administrative body that may be
required under applicable state securities laws in connection with the issuance
of shares of Common Stock upon conversion of the Preferred Shares.

     Section 6.04 Corporate Existence. The Company shall maintain and, except as
                  -------------------
otherwise permitted by Section 6.14 cause each of its subsidiaries to maintain,
their respective corporate existence, rights and franchises in full force and
effect.

                  -------------------------------
and cause each of its subsidiaries to maintain as to their respective properties
and business, with financially sound and reputable insurers, insurance against
such casualties and contingencies and of such types and in such amounts as is
customary for companies similarly situated, which insurance shall be deemed by
the Company to be sufficient. The Company shall not cause or permit any
assignment or change in beneficiary and shall not borrow against such policy.

     Section 6.06 Inspection. The Company shall permit and cause each of its
                  ----------
subsidiaries to permit each Purchaser and such persons as it may designate, such
persons to be reasonably acceptable to the Company, at such Purchaser's expense,
at reasonable times and upon reasonable notice, to visit and inspect any of the
properties of the Company and its subsidiaries, examine their books and take
copies and extracts therefrom, discuss the affairs, finances and accounts of the
Company and its subsidiaries with their officers, employees and public
accountants (and the Company hereby authorizes said accountants to discuss with
such Purchaser and such designees such affairs, finances and accounts).

     Section 6.07 Restrictive Agreements Prohibited. Neither the Company nor any
                  ---------------------------------
of its subsidiaries shall become a party to any agreement which by its terms
restricts the Company's performance of this Agreement, the Registration Rights
Agreement, the Stockholders Agreement or the Charter.

     Section 6.08 Transactions with Affiliates. Except for transactions
                  ----------------------------
contemplated by this Agreement (including entering into the Interactive Services
Agreement and a Warrant Agreement in connection therewith) or as otherwise
approved by the Compensation Committee (as defined below), neither the Company
nor any of its subsidiaries shall enter into any transaction with any director,
officer, employee or holder of more than 5% of the outstanding capital stock of
any class or series of capital stock of the Company or any of its subsidiaries,
member of the family of any such person, or any corporation, partnership, trust
or other entity in which any such person, or member of the family of any such
person, is a director, officer, trustee, partner or holder of more than 5% of
the outstanding capital stock thereof (an "Affiliate"), except for transactions
on customary terms related to such Affiliate's employment (which transactions
are subject to Section 6.19 hereof). Notwithstanding the foregoing, nothing
herein shall be deemed to restrict the Company from providing to an Affiliate
the services the Company regularly provides to its customers on the same terms
regularly made available to such customers.

     Section 6.09 Expenses of Directors. The Company shall promptly reimburse in
                  ---------------------

determination shall comply with the requirements of Treasury Regulation Section

relevant Purchasers obtaining from the prospective buyer of Preferred Shares or

reasonably necessary to meet such Purchaser's reporting obligations).

confidential information of the Company pursuant to the requirement or request
of a governmental body with jurisdiction, to the extent such disclosure is
required by a valid and applicable statute, rule, regulation, order, decree,
judgment or similar act, and notice is given by such Purchaser to the Company of
any such requirement or request, which notice is adequate to enable the Company
to seasonably seek an appropriate protective order or exemption from such
requirement or request.

     Section 6.22 Right of First Refusal upon Sale of Company.
                  -------------------------------------------

          (a)  Before the Company accepts a bona fide offer from a third party
(the "Proposed Acquirer") to acquire greater than forty percent (40%) of the
fully diluted capital stock of the Company (the "Offered Shares"), whether by
sale of stock, merger, sale of substantially all of its assets or otherwise, the
Company shall transmit such bona fide offer (the "Offer Notice") to AOL who
shall have the right, as described herein, to acquire the Offered Shares on
terms and conditions, including price, not less favorable to AOL than those
applying to the Proposed Acquirer. The Offer Notice shall disclose the identity
of the Proposed Acquirer, the Offered Shares proposed to be sold, the terms and
conditions, including price, of the proposed sale, and any other material facts
relating to the proposed sale. If the consideration is readily marketable, the
fair market value thereof shall be determined on the date of the Offer,
otherwise, the value shall be determined by mutual agreement of the Company and
AOL, and, if no agreement is reached, then the value shall be determined by a
third party mutually agreeable to the Company and AOL. Notwithstanding the
foregoing, the rights described in this Section 7.22 shall not apply to any
transaction in which the Company will acquire another business entity, by merger
or otherwise, and in which the stockholders of the Company immediately prior to
the acquisition will hold a majority of the voting securities of the resulting
entity immediately after the acquisition.

          (b)  If AOL elects to purchase the Offered Shares, AOL shall
communicate such election in writing ("Written Election") to the Company within
thirty (30) days of the date of the Offer Notice. The Written Election shall,
when taken in conjunction with the Offer Notice, be deemed to constitute a
valid, legally binding and enforceable agreement for the sale and purchase of
such Offered Shares. The closing of the sale of the Offered Shares to AOL
pursuant to this Section 6.23 shall be made at the offices of the Company on the
thirtieth (30th) day following receipt by the Company of the Written Election
(or if such 30th day is not a business day, then on the next succeeding business
day).

          (c)  If the Company has not received a Written Election from AOL
within thirty (30) days of the date of the Offer Notice, or if at any time
during that period AOL indicates in writing its decision not to purchase the
Offered Shares, the Company may accept the offer of the Proposed Acquirer. Any
such sale shall be to the Proposed Acquirer at not less than the price, and upon
other terms and conditions, if any, not more favorable to the Proposed Acquirer
than those specified in the Offer Notice.

          (d)  The rights granted to AOL hereunder are subject to the rights, if
any, of the other Major Purchasers under Section 6.2 hereof, and of Thomson
under Section 3.01 of the Thomson Agreement.

     Section 6.23 Right of First Offer.
                  --------------------

          (a)  Notification of Offer. Except as otherwise provided in the
               ---------------------
following sentence, if the Company wishes to sell, exchange, convey, convert,
transfer or otherwise dispose of ("Transfer") greater than forty percent (40%)
of the fully diluted capital stock of the Company, whether by sale of stock,
merger, sale of substantially all of its assets or otherwise, the

                                       27
<PAGE>

Company agrees that it will advise AOL by written notice (the "Notification") of
                                                               ------------
such offer, specifying (i) the number of shares of capital stock proposed to be
Transferred (the "Offered Shares"), (ii) a price per share which shall be the
                  ------- ------
minimum price at which the Company proposes to effect the Transfer (the "Minimum
                                                                         -------
Price"), and (iii) all other material terms of the proposed Transfer.
-----
Notwithstanding the foregoing, the rights described in this Section 6.23 shall
not apply to any transaction in which the Company will acquire another business
entity, by merger or otherwise, and in which the stockholders of the Company
immediately prior to the acquisition will hold a majority of the voting
securities of the resulting entity immediately after the acquisition.

          (b) Terms of Offer. The Notification shall be deemed to be an offer
              --------------
(the "Offer") to Transfer all (but not less than all) of the Offered Shares to
AOL at the Minimum Price and on the other terms and conditions of the proposed
Transfer. In the event that all or any part of the consideration is
consideration other than cash or cash equivalents, the Minimum Price shall mean
the Fair Market Value of such consideration (as hereinafter defined). AOL shall
accept or reject the Offer as soon as practicable after receipt of the
Notification, and in any case by written notice within thirty (30) days after
receipt of the Notification, or within ten (10) days after the determination of
Fair Market Value if later. Failure by AOL to give written notice of rejection
or acceptance within such time shall be deemed a rejection in accordance with
the terms of Subsection (d) below.

          (c) Acceptance of Offer. In the event AOL elects to accept the Offer,
              -------------------
it shall communicate such election to the Company by written notice.
Communication of such election (the "Acceptance") shall, when taken in
conjunction with the Notification, constitute a valid and legally binding
purchase and sale agreement. Payment in cash (or on such other terms and
conditions as shall have been specified in the Notification) shall be made at a
closing (the "Closing") within thirty (30) days after the delivery of such
Acceptance. If such Closing does not occur within thirty (30) days after the
delivery of such Acceptance, the Acceptance shall be treated as a rejection in
accordance with the terms of Subsection (d) below.

          (d) Rejection of Offer. In the event AOL rejects the Offer, it shall
              ------------------
communicate such election to the Company by written notice. Immediately
following such rejection (including a rejection for failure to accept the offer
as specified in (b) and (c) above), and for a period of one-hundred eighty (180)
days thereafter, the Company shall be free to offer and Transfer all of the
Offered Shares, at a price equal to or greater than the Minimum Price and on
other terms and conditions no less favorable than those contained in the Offer.

          (e) Fair Market Value. "Fair Market Value," as used in this Section
              -----------------
6.23 means, with respect to consideration other than cash or cash equivalents,
if the consideration is readily marketable, the fair market value thereof as
determined on the date of the Offer, otherwise, the value as determined by
mutual agreement of the Company and AOL, and, if no agreement is reached, then
the value as determined by a third party mutually agreeable to the Company and
AOL.

                                       28

          (f)  The rights granted to AOL hereunder are subject to the rights, if
any, of the Major Purchasers pursuant to the Series D Purchase Agreement, and of
Thomson under Section 3.01 of the Thomson Agreement.

     Section 6.24 Stock Option Plan. The Company shall not increase the number
                  -----------------
of shares of Common Stock under all of its stock option plans covering its
employees, Directors and consultants, in excess of fifteen percent (15%) of the
outstanding capital stock of the Company on a fully diluted basis without the
written approval of the holders of a majority of the outstanding shares of
Preferred Stock voting as a single class.

     Section 6.25 Termination of Covenants. All of the covenants set forth in
                  ------------------------
this Agreement shall survive the termination of this Agreement, provided,
however, that all of the covenants set forth in this Article VI, except for
Sections 6.18 and 6.21, shall terminate and be of no further force or effect
upon the completion of a firm commitment underwritten public offering of the

Purchasers.


SECTION 2.07

The Company has filed suit in the U.S. District Court for the District of
Massachusetts against c-Call, Inc., seeking to protect its "Streetevents"

agreement in the form of Exhibit D. However, each of these employees signed a
similar agreement with the Company's predecessor, CCBN.COM, LLC, and, by the
terms of the transaction transforming CCBN.COM, LLC into CCBN.COM, Inc., those
agreements remain in full force. The Company is nonetheless seeking the
signatures of these employees on the new form of agreement and expects to
receive them shortly.
