Item 14. Indemnification of Directors and Officers

   Article EIGHTH of our amended and restated certificate of incorporation to
be effective upon the closing of this offering provides that none of our
directors shall be personally liable for any monetary damages for any breach of
fiduciary duty as a director, except to the extent that the Delaware General
Corporation Law prohibits the elimination or limitation of liability of
directors for breach of fiduciary duty.

   Article NINTH of our amended and restated certificate of incorporation
provides that our directors and officers (a) shall be indemnified by us against
all expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement incurred in connection with any litigation or other legal proceeding
(other than an action by or in our right) brought against him by virtue of his
position as our director or officer if he acted in good faith and in a manner
he reasonably believed to be in, or not opposed to, our best interests, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful and (b) shall be indemnified by us against all
expenses (including attorneys' fees) and amounts paid in settlement incurred in
connection with any action by or in our right brought against him by virtue of
his position as our director or officer if he acted in good faith and in a
manner he reasonably believed to be in, or not opposed to, our best interests,
except that no indemnification shall be made with respect to any matter as to
which such person shall have been adjudged to be liable to us, unless a court
determines that, despite such adjudication but in view of all of the
circumstances, he is entitled to indemnification of such expenses.
Notwithstanding the foregoing, to the extent that a director or officer has
been successful, on the merits or otherwise, including, without limitation, the
dismissal of an action without prejudice, he is required to be indemnified by
us against all expenses (including attorneys' fees) incurred in

                                      II-1
<PAGE>

connection therewith. Expenses shall be advanced to a director or officer at
his request, provided that he undertakes to repay the amount advanced if it is
ultimately determined that he is not entitled to indemnification for such
expenses.

   Indemnification is required to be made unless we determine that the
applicable standard of conduct required for indemnification has not been met.
In the event of a determination by us that the director or officer did not meet
the applicable standard of conduct required for indemnification, or if we fail
to make an indemnification payment within 60 days after such payment is claimed
by such person, such person is permitted to petition the court to make an
independent determination as to whether such person is entitled to
indemnification. As a condition precedent to the right of indemnification, the
director or officer must give us notice of the action for which indemnity is
sought and we have the right to participate in such action or assume the
defense thereof.

   Article NINTH of our amended and restated certificate of incorporation
further provides that the indemnification provided therein is not exclusive,
and provides that in the event that the Delaware General Corporation Law is
amended to expand the indemnification permitted to directors or officers we
must indemnify those persons to the fullest extent permitted by such law as so
amended.

   Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent
of the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceeding to which he is or is threatened to be
made a party by reason of such position, if such person shall have acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, in any criminal proceeding, if such
person had no reasonable cause to believe his conduct was unlawful; provided
that, in the case of actions brought by or in the right of the corporation, no
indemnification shall be made with respect to any matter as to which such
person shall have been adjudged to be liable to the corporation unless and only
to the extent that the adjudicating court determines that such indemnification
is proper under the circumstances.

   Under section   of the underwriting agreement between us and the
underwriters, the underwriters are obligated, under certain circumstances, to
indemnify our directors and officers against certain liabilities, including
liabilities under the Securities Act.

Item 15. Recent Sales of Unregistered Securities

   Set forth in chronological order is information regarding securities issued
by us since August 1997. Further included is the consideration, if any,
received by us for such securities and information relating to the section of
the Securities Act or rule of the Securities and Exchange Commission under
which exemption from registration was claimed. For purposes of this Item 15,
common units and shares of our common stock do not reflect the three-for-one
split effected on       , 2000.

   The securities issued in the following transactions were either (i) offered
and sold in reliance upon exemptions from Securities Act registration set forth
in Sections 3(b) and 4(2) of the Securities Act, or any regulations promulgated
thereunder, relating to sales by an issuer not involving any public offering,
or (ii) in the case of certain options to purchase shares of Series A common
stock and shares of Series A common stock issued upon the exercise of such
options, such offers and sales were made in reliance upon an exemption from
registration under Rule 701 of the Securities Act. No underwriters were
involved in these sales of securities.

Item 17. Undertakings

   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and persons who control us pursuant to
the provisions of our amended and restated certificate of incorporation and the
laws of the State of Delaware, or otherwise, we have been advised that, in the
opinion of the Securities and Exchange Commission, such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by us of expenses incurred or paid by a
director, officer or controlling person of us in the successful defense of any
action, suit or proceeding) is asserted by a director, officer or person who
controls us in connection with the securities being registered, we will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

   We hereby undertake to provide to the underwriters at the closing specified
in the underwriting agreement certificates in such denominations and registered
in such names as required by the underwriters to permit prompt delivery to each
purchaser.

   We hereby undertake that:

  (1) For purposes of determining any liability under the Securities Act, the
      information omitted form the form of prospectus filed as part of this
      registration statement in reliance upon Rule 430A and contained in a
      form of prospectus filed by us pursuant to Rule 424(b)(1) or (4) or
      497(h) under the Securities Act shall be deemed to be part of this
      registration statement as of the time it was declared effective.

  (2) For the purpose of determining any liability under the Securities Act,
      each post-effective amendment that contains a form of prospectus shall
      be deemed to be a new registration statement relating to the securities
      offered therein, and the offering of such securities at that time shall
      be deemed to be the initial bona fide offering thereof.

<PAGE>

terms of the Series E Preferred Stock as set forth herein, differing from the

complying with the conditions of the Certificate of Incorporation, the right to
have such vote being expressly waived by all present and future holders of the

     The powers, preferences and rights, and the qualifications, limitations or
restrictions thereof, in respect of each class or series of stock of the

Section 1.  Liquidation Rights.
- ----------  ------------------

       (a)     Liquidation Payments.
               --------------------

               (i)   Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, before any distribution or
payment is made upon any stock ranking on liquidation junior to the Preferred
Stock, each holder of Series D Preferred Stock and Series E Preferred Stock
shall first be entitled, followed by all other classes of Preferred Stock, to be
paid with respect to each such share an amount equal to the greater of (i) the
Original Purchase Price of such share (which amount shall be subject to
equitable adjustment whenever there shall occur a stock dividend, stock split,
combination of shares, reclassification or other similar event with respect to
the Preferred Stock), plus all dividends accrued or declared but unpaid thereon,
to and including the date full payment shall be tendered to the holders of the
Preferred Stock with respect to such liquidation, dissolution or winding up, or
(ii) such amount as would have been payable had such share been converted to
Common Stock pursuant to Section 2 immediately prior to such liquidation,
dissolution or winding up, and the holders of Preferred Stock shall not be
entitled to any further payment, such amount payable with respect to the
Preferred Stock being sometimes referred to as the "Liquidation Payment". In the
case of the Series A Preferred Stock, the Original Purchase Price per share
shall be $2.67. In the case of the Series B Preferred Stock, the Original
Purchase Price per share shall be $3.33. In the case of the Series C Preferred
Stock, the Original Purchase Price per share shall be $5.0133. In the case of
the Series D Preferred Stock, the Original Purchase Price per share shall be
$9.417. In the case of the Series E-1 Preferred Stock, the Original Purchase
Price per share shall be $16.10. The Original Purchase Price of each subseries
of the Undesignated Series E Stock shall be determined by the Board of Directors
upon its designation of each such subseries.

                                       3
<PAGE>

     If upon such liquidation, dissolution or winding up of the Corporation,
whether voluntary or involuntary, the assets to be distributed among the holders
of Preferred Stock shall be insufficient to permit payment to the holders of
Preferred Stock of the amount distributable as aforesaid, then the assets shall
be distributed first to the holders of the Series D Preferred Stock and Series E
Preferred Stock to satisfy the entire Liquidation Payment due each holder of
Series D Preferred Stock and Series E Preferred Stock, and in the event the
assets to be distributed shall be insufficient to satisfy the Liquidation
Payments due the holders of the Series D Preferred Stock and Series E Preferred
Stock, then the assets to be so distributed shall be distributed pro rata among
                                                                 --------
the holders of the Series D Preferred Stock and Series E Preferred Stock in
accordance with the respective amounts which would have been distributed to such
holders if such assets had been sufficient to make the Liquidation Payments in
full. Following the distribution to the holders of the Series D Preferred Stock
and Series E Preferred Stock, in the case where assets are insufficient to
satisfy the Liquidation Payments to all classes of Preferred Stock, any
remaining assets of the Corporation to be distributed shall be distributed pro
                                                                           ---
rata among the holders of the other classes of Preferred Stock in accordance
- ----
with the respective amounts which would have been distributed to such holders if
such assets had been sufficient to make the Liquidation Payments in full.
Written notice of such liquidation, dissolution or winding up, stating a payment
date, the amount of the Liquidation Payments and the place where said
Liquidation Payments shall be payable, shall be delivered in person, mailed by
certified or registered mail, return receipt requested, or sent by telecopier or
telex, not less than 20 days prior to the payment date stated therein, to the
holders of record of Preferred Stock, such notice to be addressed to each such
holder at its address as shown by the records of the Corporation.

          (ii)   Upon any liquidation, dissolution or winding up as described in
Subsection 1(a)(i), after the payments described in such subsection shall have
been made in full to the holders of the Preferred Stock, or funds necessary for
such payments shall have been set aside by the Corporation in trust for the
account of holders of Preferred Stock so as to be available for such payments,
the remaining assets available for distribution shall be distributed among the
holders of the Common Stock ratably in proportion to the number of shares of
Common Stock then held by them, provided, however, that the amount distributed
                                --------- -------
to each holder of Series B Common Stock, Series C Common Stock, Series D Common
Stock and Series E Common Stock in respect of each such share held by each such
person shall be reduced by the Effective Issuance Value (as defined in Section
2(b)(ii)(A) hereof) of each such share, and the assets then additionally
available for distribution as a result of all such reductions shall be
distributed ratably among all shareholders in proportion to the number of shares
held by them, counting all shares of Preferred Stock as if they had been
converted to Common Stock at the then-applicable Conversion Rate.

          (iii)  Upon conversion of shares of Preferred Stock into shares of
Series A Common Stock pursuant to Section 2 below, the holder of such Series A
Common Stock shall not be entitled to any preferential payment or distribution
in case of any liquidation, dissolution or winding up, but shall share ratably
in any distribution of the assets of the Corporation to all the holders of
Common Stock.

     (b)  Distributions Other than Cash. Whenever the distributions provided for
          -----------------------------
in this Section 1 shall be payable in property other than cash, the value of
such distributions shall be the



                                       4
<PAGE>

fair market value of such property as determined in good faith by the Board of
Directors of the Corporation.

     (c)  Merger as Liquidation, etc. The merger or consolidation of the
          --------------------------
Corporation into or with another corporation (except one in which the holders of
capital stock of the Corporation immediately prior to such merger or
consolidation continue to hold at least fifty percent (50%) in voting power of
the capital stock of the surviving corporation immediately after the merger, in
which case the provisions of Subsection 2(g) shall apply), or the sale of all or
substantially all of the assets of the Corporation, shall be deemed to be a
liquidation, dissolution or winding up of the affairs of the Corporation for
purposes of this Section 1 with respect to the Preferred Stock unless the
holders of at least a majority of the then outstanding shares of Preferred Stock
elect to the contrary, such election to be made by giving written notice thereof
to the Corporation at least three days before the effective date of such event.
If such notice is given, the provisions of Subsection 2(g) shall apply to such
Preferred Stock. Unless such election is made, any amounts received by the
holders of the Preferred Stock as a result of such merger or consolidation shall
be deemed to be applied toward, and all consideration received by the
Corporation in such asset sale together with all other available assets of the
Corporation shall be distributed toward, the Liquidation Payments attributable
to such shares of Preferred Stock.

     (d)  Notice. Written notice of any proposed liquidation, dissolution or
          ------
winding up of the affairs of the Corporation (including any merger,
consolidation or sale of assets which may be deemed to be a liquidation,
dissolution or winding up of the affairs of the Corporation under Subsection
1(c)), stating a payment date, the amount of the Liquidation Payments and the
place where said Liquidation Payments shall be payable, shall be given to the
holders of record of the Preferred Stock by first class mail, postage prepaid,
or by fax or DHL, Federal Express or other recognized express international
courier service in the case of non-U.S. stockholders, not less than twenty (20)
days prior to the payment date stated therein, such notice to be addressed to
each such holder at its address as shown by the records of the Corporation. Any
holder of outstanding shares of Preferred Stock may waive any notice required by
this Subsection by a written document specifically indicating such waiver.

Section 2. Conversion. The holders of Preferred Stock shall have conversion
- ---------  ----------
rights as follows (the "Conversion Rights"):

     (a)  Right to Convert; Conversion Price. Each share of Preferred Stock
          ----------------------------------
shall be convertible, without the payment of any additional consideration by the
holder thereof and at the option of the holder thereof, at any time after the
date of issuance of such share, at the office of the Corporation or any transfer
agent for the Preferred Stock, into such number of fully paid and nonassessable
shares of Series A Common Stock as is determined in accordance with the
following:

          (i)   in the case of the Series E Preferred Stock, by dividing the
Original Purchase Price of the relevant subseries of Series E Preferred Stock by
the relevant Series E Conversion Price for that subseries, determined as
hereinafter provided, in effect at the time of conversion. The Conversion Price
at which shares of Series A Common Stock shall be deliverable upon conversion of
any subseries of Series E Preferred Stock without the payment of

                                       5
<PAGE>

any additional consideration by the holder thereof (the "Series E Conversion
Price") shall initially be the Original Purchase Price of such subseries per
share of Series A Common Stock. Such initial Series E Conversion Price shall be
subject to adjustment in accordance with Section 2(h) hereof, in order to adjust
the number of shares of Series A Common Stock into which the Series E Preferred
Stock is convertible;

          (ii)   in the case of the Series D Preferred Stock, by dividing $9.417
by the Series D Conversion Price, determined as hereinafter provided, in effect
at the time of conversion. The Conversion Price at which shares of Series A
Common Stock shall be deliverable upon conversion of Series D Preferred Stock
without the payment of any additional consideration by the holder thereof (the
"Series D Conversion Price") shall initially be $9.417 per share of Series A
Common Stock. Such initial Series D Conversion Price shall be subject to
adjustment in accordance with Section 2(h) hereof, in order to adjust the number
of shares of Series A Common Stock into which the Series D Preferred Stock is
convertible;

          (iii)  in the case of the Series C Preferred Stock, by dividing
$5.0133 by the Series C Conversion Price, determined as hereinafter provided,
in effect at the time of conversion. The Conversion Price at which shares of
Common Stock shall be deliverable upon conversion of Series C Preferred Stock
without the payment of any additional consideration by the holder thereof (the
"Series C Conversion Price") shall be $5.0133 per share of Common Stock;

          (iv)   in the case of the Series B Preferred Stock, by dividing $3.33
by the Series B Conversion Price, determined as hereinafter provided, in effect
at the time of conversion. The Conversion Price at which shares of Common Stock
shall be deliverable upon conversion of Series B Preferred Stock without the
payment of any additional consideration by the holder thereof (the "Series B
Conversion Price") shall be $3.33 per share of Common Stock; and

          (v)    in the case of the Series A Preferred Stock, by dividing $2.67
by the Series A Conversion Price, determined as hereinafter provided, in effect
at the time of conversion. The Conversion Price at which shares of Common Stock
shall be deliverable upon conversion of Series A Preferred Stock without the
payment of any additional consideration by the holder thereof (the "Series A
Conversion Price") shall be $2.67 per share of Common Stock.

     (b)  Automatic Conversion.
          --------------------

          (i)    Automatic Conversion of Preferred Stock. If at any time (i) the
                 ---------------------------------------
Corporation shall effect a firm commitment underwritten public offering of
shares of Common Stock in which (A) the aggregate price paid for such shares by
the public shall be at least $30,000,000 and (B) the Company has a pre-offering
valuation of at least $150,000,000 (a "Qualified Public Offering") or (ii) the
holders of not less than a majority of the shares of Preferred Stock have
elected in writing to convert such shares into Common Stock pursuant to this
Section 2, then effective upon the closing of the sale of such shares by the
Corporation pursuant to such public offering or such conversion, as the case may
be, all outstanding shares of Preferred Stock shall automatically convert to
shares of Common Stock on the basis set forth in this Section 2, provided that
                                                                 -------- ----
in the case where a majority of the shares of Preferred Stock have


                                       6
<PAGE>

elected to convert to Common Stock, the outstanding shares of Series D Preferred
Stock and Series E Preferred Stock will not be converted into shares of Common
Stock unless holders of a majority of shares of Series D Preferred Stock and
Series E Preferred Stock have elected in writing, voting as a single class, to
convert such shares into Common Stock pursuant to this Section 2. Holders of
shares of Preferred Stock so converted may deliver to the Corporation at its
principal office (or such other office or agency of the Corporation as the
Corporation may designate by notice in writing to such holders) during its usual
business hours, the certificate or certificates for the shares so converted. As
promptly as practicable thereafter, the Corporation shall issue and deliver to
such holder a certificate or certificates for the number of whole shares of
Common Stock to which such holder is entitled, together with any cash dividends
and payment in lieu of fractional shares to which such holder may be entitled
pursuant to subsections 2(c) and 2(d). Until such time as a holder of shares of
Preferred Stock shall surrender his or its certificates therefor as provided
above, such certificates shall be deemed to represent the shares of Common Stock
to which such holder shall be entitled upon the surrender thereof.

          (ii)   Forced Conversion of Common Stock. At the election of the Board
                 ---------------------------------
of Directors, upon any Forced Conversion Event (as hereinafter defined), each
share of Series B Common Stock, Series C Common Stock, Series D Common Stock and
Series E Common Stock (collectively, "Convertible Common Stock") shall
automatically be converted into such number of shares of Series A Common Stock
as is equal to:

                                              1 - (EIV/CV)

where "EIV" is the applicable Effective Issuance Value (as hereinafter defined)
for the Series of Common Stock being converted and "CV" is the Current Value of
a share of the Corporation's stock on a fully diluted basis, as further
described below.

          For purposes of this Section 2(b)(ii) and Section 1(a)(ii), the
following terms shall have the following meanings:

                    (A)  "Effective Issuance Value" means:

                              (I) with respect to the Series B Common Stock:
                    $0.46;

                              (II) with respect to the Series C Common Stock:
                    $0.62;

                              (III) with respect to the Series D Common Stock:
                    $0.61; and

                              (IV) with respect to the Series E Common Stock:
                    $0.97.

                    (B)  "Forced Conversion Event" means any of the following
               events:

                                       7
<PAGE>

                              (I)   the closing of a Qualified Public Offering;

                              (II)  the merger or consolidation of the
                         Corporation into or with another corporation (a
                         "Merger");
                         or

                              (III) the sale of all or substantially all of the
                         assets of the Corporation (an "Asset Sale").

                    (C) "Current Value" means a number determined as follows:

                              (I)   if the Forced Conversion Event is a
                         Qualified Public Offering, the Current Value shall be
                         the offering price per share (prior to underwriter
                         commissions and discounts) in such Qualified Public
                         Offering;

                              (II)  if the Forced Conversion Event is a Merger
                         or Asset Sale, the Current Value shall be the total
                         fair market value of the consideration paid to the
                         Corporation's stockholders in respect of the Common
                         Stock and Preferred Stock then held by them, divided by
                         the sum of (x) the total number of shares of Common
                         Stock then outstanding and (y) the total number of
                         shares of Common Stock into which all shares of
                         Preferred Stock then outstanding are then convertible.

          If a Forced Conversion Event giving rise to an automatic conversion
under this Section 2(b)(ii) is a Qualified Public Offering, the person(s)
entitled to receive the Series A Common Stock issuable upon conversion of Common
Stock shall not be deemed to have converted that Common Stock until the closing
of such offering.

     (c)  Mechanics of Automatic and Forced Conversions. With respect to the
          ------------ ------------- ------------------
Preferred Stock, upon the occurrence of a Qualified Public Offering, and with
respect to the Convertible Common Stock, upon the occurrence of a Forced
Conversion Event (provided that the Board of Directors has elected to cause a
conversion of Convertible Common Stock in connection with such Forced Conversion
Event), such stock shall be converted automatically without any further action
by the holders of such shares and whether or not the certificates representing
such shares we surrendered to the Corporation or its transfer agent; provided,
however, that all holders of shares of stock to be converted shall be given
written notice of the occurrence the event pursuant to which such automatic or
forced conversion is occurring including the date such event occurred (the
"Mandatory Conversion Date"), and the Corporation shall not be obligated to
issue certificates evidencing the shares of Series A Common Stock issuable upon
such conversion unless certificates evidencing such shares of the Preferred
Stock or Convertible Common Stock being converted are either delivered to the
Corporation or its transfer agent, or the holder notifies the Corporation or any
transfer agent that such certificates have been lost, stolen, or destroyed

                                       8
<PAGE>

and executes an agreement satisfactory to the Corporation to indemnify the
Corporation from any loss incurred by it in connection therewith and, if the
Corporation so elects, provides an appropriate indemnity bond. On the Mandatory
Conversion Date, all rights and limitations with respect to the Preferred Stock
and Convertible Common Stock so converted shall terminate, except any of the
rights of the holder thereof, upon surrender of the holder's certificate or
certificates therefor, to receive certificates for the number of shares of
Series A Common Stock into which such Preferred Stock or Convertible Common
Stock has been converted, together with cash in an amount equal to all dividends
declared but unpaid on, and any and all other amounts owing with respect to, the
shares of Preferred Stock or Convertible Common Stock so converted to and
including the time of conversion. Upon the automatic conversion of the Preferred
Stock or the Convertible Common Stock, the holders of such Preferred Stock or
Convertible Common Stock, as the case may be, shall surrender the certificates
representing such shares at the office of the Corporation or of its transfer
agent. If so required by the Corporation, certificates surrendered for
conversion shall be endorsed or accompanied by written instrument or instruments
of transfer, in form satisfactory to the Corporation, duly executed by the
registered holder or by the holder's attorney duly authorized in writing. Upon
surrender of such certificates there shall be issued and delivered to such
holder, promptly at such office and in the holder's name as shown on such
surrendered certificate or certificates, a certificate or certificates for the
number of shares of Series A Common Stock into which the shares of the Preferred
Stock or Convertible Common Stock surrendered were convertible on the date on
which such automatic conversion occurred, together with cash in an amount equal
to all dividends declared but unpaid on, and any and all other amounts owing
with respect to, the shares of Convertible Common Stock or Preferred Stock
converted to and including the time of conversion. No fractional share of Series
A Common Stock shall be issued upon the automatic conversion of the Preferred
Stock or Convertible Common Stock. In lieu of any fractional share to which the
holder would otherwise be entitled, the Corporation shall pay, with respect to
Preferred Stock, cash equal to such fraction multiplied by the applicable
Conversion Price then in effect, and with respect to the Convertible Common
Stock, cash equal to such fraction multiplied by Current Value (as defined in
paragraph 2(b)(ii)(C) above).

     (d) Mechanics of Optional Conversions. Before any holder of Preferred Stock
         ------------ --------------------
shall be entitled to convert the same into shares of Series A Common Stock, the
holder shall surrender the certificate or certificates therefor at the office of
the Corporation or of any transfer agent for the Preferred Stock, and shall give
written notice to the Corporation at such office that the holder elects to
convert the same and shall state therein the holder's name or the name or names
of the holder's nominees in which the holder wishes the certificate or
certificates for shares of Series A Common Stock to be issued. On the date of
conversion, all rights with respect to the Preferred Stock so converted shall
terminate, except any of the rights of the holder thereof, upon surrender of the
holder's certificate or certificates therefor, to receive certificates for the
number of shares of Series A Common Stock into which such Preferred Stock has
been converted and cash in an amount equal to all dividends declared but unpaid
on, and any and all other amounts owing with respect to, the shares of Preferred
Stock being converted to and including the time of conversion. If so required by
the Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by written instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder or by
the holder's attorney duly authorized in writing. No fractional share of Series
A Common Stock shall be issued upon the optional

                               9
<PAGE>

conversion of Preferred Stock. In lieu of any fractional share to which the
holder would otherwise be entitled, the Corporation shall pay cash equal to such
fraction multiplied by the applicable Conversion Price then in effect. The
Corporation shall, as soon as practicable after surrender of the certificate or
certificates for conversion, issue and deliver at such office to such holder of
Preferred Stock, or to the holder's nominee or nominees, a certificate or
certificates for the number of shares of Series A Common Stock to which the
holder shall be entitled as aforesaid, together with cash in lieu of any
fraction of a share and cash in an amount equal to all dividends declared but
unpaid thereon and any and all other amounts owing with respect thereto at such
time. Such conversion shall be deemed to have been made immediately prior to the
close of business on the date of such surrender of the shares of Preferred Stock
to be converted, and the person or persons entitled to receive the shares of
Series A Common Stock issuable upon conversion shall be treated for all purposes
as the record holder or holders of such shares of Series A Common Stock on such
date.

     (e)  Adjustments for Certain Dividends and Distributions. In the event that
          ---------------------------------------------------
at any time or from time to time after the date on which a share of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock was first issued, or, with respect to the Series E Preferred
Stock, after December 1, 1999, whether or not any Series E Preferred Stock is
issued on such date (with respect to each such series of Preferred Stock, its
"Original Issue Date"), the Corporation shall make or issue, or fix a record
date for the determination of holders of Common Stock entitled to receive, a
dividend or other distribution payable in securities of the Corporation other
than shares of Common Stock, then and in each such event provision shall be made
so that the holders of Preferred Stock shall receive upon conversion thereof in
addition to the number of shares of Common Stock receivable thereupon, the
amount of securities of the Corporation that they would have received had their
Preferred Stock been converted into Common Stock on the date of such event and
had they thereafter, during the period from the date of such event to and
including the conversion date, retained such securities receivable by them as
aforesaid during such period, giving application during such period to all
adjustments called for herein.

     (f)  Adjustment for Reclassification, Exchange, or Substitution. In the
          ----------------------------------------------------------
event that at any time or from time to time after the Original Issue Date, the
Common Stock issuable upon the conversion of Preferred Stock shall be changed
into the same or a different number of shares of any class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares or stock dividend provided for above, or a
merger, consolidation, or sale of assets provided for below), then and in each
such event the holder of any share or shares of Preferred Stock shall have the
right thereafter to convert such shares into the kind and amount of shares of
stock and other securities and property receivable upon such reorganization,
reclassification, or other change, by the holder of a number of shares of Common
Stock equal to the number of shares of Common Stock into which such shares of
Preferred Stock might have been converted immediately prior to such
reorganization, reclassification, or change, all subject to further adjustment
as provided herein.

     (g)  Adjustment for Merger, Consolidation or Sale of Assets. In the event
          ------------------------------------------------------
that at any time or from time to time after the Original Issue Date, the
Corporation shall merge or consolidate with or into another entity or sell all
or substantially all of its assets, each share of

                                      10
<PAGE>

Preferred Stock as to which such consolidation, merger or sale is not treated as
a liquidation under Subsection 1(c) shall thereafter be convertible into the
kind and amount of shares of stock or other securities or property to which a
holder of the number of shares of Common Stock of the Corporation deliverable
upon conversion of such Preferred Stock would have been entitled to receive upon
such consolidation, merger or sale; and, in such case, appropriate adjustment
(as determined in good faith by the Board of Directors) shall be made in the
application of the provisions set forth in this Section 2 with respect to the
rights and interest thereafter of the holders of Preferred Stock, to the end
that the provisions set forth in this Section 2 (including provisions with
respect to changes in and other adjustments of the Conversion Price) shall
thereafter be applicable, as nearly as reasonably may be, in relation to any
shares of stock or other property thereafter deliverable upon the conversion of
Preferred Stock.

     (h)  Adjustments to Series D Conversion Price and Series E Conversion Price
          ----------------------------------------------------------------------
for Dilutive Issuances:
- ----------------------

          (i)  Special Definitions. For purposes of this Subsection 2(h), the
               -------------------
following definitions shall apply:

               (A) "Option" shall mean rights, options or warrants to subscribe
                    ------
for, purchase or otherwise acquire Common Stock or Convertible Securities.

               (B) "Convertible Securities" shall mean any evidences of
                    ----------------------
indebtedness, shares or other securities directly or indirectly convertible into
or exchangeable for Common Stock.

               (C) "Additional Shares of Common Stock" shall mean all shares of
                    ---------------------------------
Common Stock issued (or, pursuant to Subsection 2(h)(iii) below, deemed to be
issued) by the Corporation after the Series E Original Issue Date, other than:

                   (I)   shares of Common Stock issued or issuable as a dividend
                         or other distribution on Preferred Stock;

                   (II)  shares of Common Stock issued or issuable by reason of
                         a dividend or other distribution on shares of Common
                         Stock that is covered by Subsection 2(e) above;

                   (III) shares of Common Stock issued or issuable upon
                         conversion of those shares of Preferred Stock
                         outstanding at the close of business on the Series E
                         Original Issue Date;

                   (IV)  shares of Common Stock issued or issuable upon
                         conversion of the Convertible Common Stock.

                   (V)   shares of Common Stock or options to acquire Common
                         Stock approved by the Compensation Committee (acting
                         alone or with the Board of Directors) of the
                         Corporation,

                                      11
<PAGE>

                         issued or issuable to employees or directors of, or
                         consultants to, the Corporation pursuant to plans
                         adopted by the Board of Directors of the Corporation,
                         so long as the total of all stock options or stock
                         grants issued under all of the Corporation's stock
                         option plans does not exceed 25% of the outstanding
                         capital stock of the Corporation on a fully diluted
                         basis.

           (D) For purposes of this Section 2(h), the term "Series E" shall be
deemed to refer separately to each subseries of the Series E Stock.

     (ii)  No Adjustment of Conversion Price. No adjustment in the number of
           ---------------------------------
shares of Common Stock into which the Series D Preferred Stock or the Series H
Preferred Stock is convertible shall be made (a) unless the consideration per
share (determined pursuant to Subsection 2(h)(v)) for an Additional Share of
Common Stock issued or deemed to be issued by the Corporation is less than the
applicable Conversion Price in effect on the date of, and immediately prior to,
the issue of such Additional Shares, or (b) if prior to or within 60 days
subsequent to such issuance, the Corporation receives written notice from the
holders of at least 66% of the then outstanding shares of Series D Preferred
Stock and Series E Preferred Stock, voting as a single class, agreeing that no
such adjustment shall be made as the result of the issuance of Additional Shares
of Common Stock.

     (iii) Issuance of Securities Deemed an Issuance of Additional Shares
           --------------------------------------------------------------
of Common Stock. If the Corporation at any time or from time to time after the
- ---------------
Series E Original Issue Date shall issue any Options or Convertible Securities
or shall fix a record date for the determination of holders of any class of
securities entitled to receive any such Options or Convertible Securities, then
the maximum number of shares of Common Stock (as set forth in the instrument
relating thereto without regard to any provision contained therein for a
subsequent adjustment of such number) issuable upon the exercise of such Options
or, in the case of Convertible Securities and Options therefor, the conversion
or exchange of such Convertible Securities, shall be deemed to be Additional
Shares of Common Stock issued as of the time of such issue or, in case such a
record date shall have been fixed, as of the close of business on such record
date, provided that Additional Shares of Common Stock shall not be deemed to
have been issued unless the consideration per share (determined pursuant to
Subsection 2(h)(v) hereof) of such Additional Shares of Common Stock would be
less than the applicable Conversion Price in effect on the date of and
immediately prior to such issue, or such record date, as the case may be, and
provided further that in any such case in which Additional Shares of Common
Stock are deemed to be issued:

           (A)  No further adjustment in the Conversion Price shall be made upon
the subsequent issue of Convertible Securities or shares of Common Stock upon
the exercise of such Options or conversion or exchange of such Convertible
Securities;

           (B)  If such Options or Convertible Securities by their terms
provide, with the passage of time or otherwise, for any increase or decrease in
the consideration payable to the Corporation, upon the exercise, conversion or
exchange thereof, the Conversion Price

                                 12
<PAGE>

computed upon the original issue thereof (or upon the occurrence of a record
date with respect thereto), and any subsequent adjustments based thereon, shall,
upon any such increase or decrease becoming effective, be recomputed to reflect
such increase or decrease insofar as it affects such Options or the rights of
conversion or exchange under such Convertible Securities;

          (C) Upon the expiration or termination of any unexercised Option, the
Conversion Price shall be readjusted, so that the Additional Shares of Common
Stock deemed issued as the result of the original issue of such Option shall not
be deemed issued for the purposes of the Conversion Price;

          (D) In the event of any change in the number of shares of Common
Stock issuable upon the exercise, conversion or exchange of any Option or
Convertible Security, including, but not limited to, a change resulting from the
anti-dilution provisions thereof, the Conversion Price then in effect shall
forthwith be readjusted to such Conversion Price as would have obtained had the
adjustment which was made upon the issuance of such Option or Convertible
Security not exercised or converted prior to such change been made upon the
basis of such change; and

          (E) No readjustment pursuant to clause (B) or (D) above shall have the
effect of increasing the Conversion Price to an amount which exceeds the lower
of (i) the Conversion Price on the original adjustment date, or (ii) the
Conversion Price that would have resulted from any issuances of Additional
Shares of Common Stock between the original adjustment date and such
readjustment date.

     In the event the Corporation, after the Series E Original Issue Date,
amends any Options or Convertible Securities (whether such Options or
Convertible Securities were outstanding on the Series E Original Issue Date or
were issued after the Series E Original Issue Date) to increase the number of
shares issuable thereunder or decrease the consideration to be paid upon
exercise or conversion thereof, then such Options or Convertible Securities, as
so amended, shall be deemed to have been issued after the Series E Original
Issue Date and the provisions of this Subsection 2(h)(iii) shall apply.

     (iv) Adjustment of Conversion Price Upon Issuance of Additional Shares
          -----------------------------------------------------------------
of Common Stock. In the event the Corporation shall at any time after the
- ---------------
Series E Original Issue Date issue Additional Shares of Common Stock (including
Additional Shares of Common Stock deemed to be issued pursuant to Subsection
2(h)(iii), but excluding shares issued as a stock split or combination as
provided in Subsection 2(f) or upon a dividend or distribution as provided in
Subsection 2(e)), without consideration or for a consideration per share less
than the applicable Series D Conversion Price and/or the Series E Conversion
Price in effect on the date of and immediately prior to such issue, then the
Series D Conversion Price and/or the Series E Conversion Price, as applicable,
in effect immediately prior to each such issuance shall forthwith (except as
otherwise provided in this clause (A)) be reduced to the price determined by
dividing (i) an amount equal to the sum of (a) the number of shares of Common
Stock outstanding immediately prior to such issue or sale multiplied by the then
existing Series D Conversion Price or Series E Conversion Price, as applicable,
and (b) the consideration, if any, received by the

                                 13
<PAGE>

Corporation upon such issue or sale, by (ii) the total number of shares of
Common Stock outstanding immediately after such issue or sale.

          (v) Determination of Consideration. For purposes of this Subsection
              ------------------------------
2(h), the consideration received by the Corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

              (A)  Cash and Property: Such consideration shall:
                   -----------------

                   (I)   insofar as it consists of cash, be computed at the
                         aggregate of cash received by the Corporation,
                         excluding amounts paid or payable for accrued interest;

                   (II)  insofar as it consists of property other than cash, be
                         computed at the fair market value thereof at the time
                         of such issue, as determined in good faith by the Board
                         of Directors; and

                   (III) in the event Additional Shares of Common Stock are
                         issued together with other shares or securities or
                         other assets of the Corporation for consideration which
                         covers both, be the proportion of such consideration so
                         received, computed as provided in clauses (I) and (II)
                         above, as determined in good faith by the Board of
                         Directors.

              (B)  Options and Convertible Securities. The consideration per
                   ----------------------------------
share received by the Corporation for Additional Shares of Common Stock deemed
to have been issued pursuant to Subsection 2(h)(iii), relating to Options and
Convertible Securities, shall be determined by dividing

                      (x) the total amount, if any, received or receivable by
the Corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the Corporation upon the exercise of such Options or the conversion or exchange
of such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities, by

                      (y) the maximum number of shares of Common Stock (as set
forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

          (vi) Multiple Closing Dates. In the event the Corporation shall issue
               ----------------------
on more than one date Additional Shares of Common Stock which are comprised of
shares of the same
                                 14
<PAGE>

series or class of Convertible Securities, and such issuance dates occur within
a period of no more than 120 days, then, upon the final such issuance, the
Conversion Price shall be adjusted to give effect to all such issuances as if
they occurred on the date of the final such issuance (and without giving effect
to any adjustments as a result of such prior issuances within such period).

     (i)  No Impairment. The Corporation shall not, by amendment of its
          -------------
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation but shall at
all times in good faith assist in the carrying out of all the provisions of this
Section 2 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of
Preferred Stock against impairment.

     (j)  Certificate as to Adjustments of the Series D Conversion Price and/or
          ---------------------------------------------------------------------
the Series E Conversion Price. Upon the occurrence of each adjustment or
- -----------------------------
readjustment of the Conversion Price of the Series D Preferred Stock or the
Series E Preferred Stock pursuant to this Section 2, the Corporation at its
expense shall promptly compute such adjustment or readjustment in accordance
with the terms hereof and furnish to each affected holder of Series D Preferred
Stock or Series E Preferred Stock, as the case may be, a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based. The Corporation shall, upon the
written request at any time of any affected holder of Series D Preferred Stock
or Series E Preferred Stock, furnish or cause to be furnished to such holder a
like certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Price at the time in effect, and (iii) the number of shares of Common
Stock and the amount, if any, of other property which at the time would be
received upon the conversion of each share of Series D Preferred Stock or Series
E Preferred Stock, as the case may be.

     (k)  Notices of Record Date. In the event of any taking by the Corporation
          ----------------------
of a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend (other

of Common Stock entitled to receive the Common Stock dividend.

          promotions set forth on Exhibit A-1. The promotions described on
          Exhibit A-1 and any other promotions provided by AOL to ICP shall be
          referred to as the "Promotions." AOL will have the right to fulfill
          the foregoing promotional commitments by providing ICP with comparable

          Network, provided that prior to providing ICP with any such comparable
          promotional placements that are [**] of the [**], AOL shall seek ICP's
          approval, which approval shall not be unreasonably withheld or

          will provide ICP, as its sole remedy, with a comparable promotional
          placement within the same AOL Property (e.g., in the case of the [**]
          within the [**])and at the same [**] as the Promotion not delivered by
          AOL. Except to the extent expressly described herein, the exact form,
          placement and nature of the Promotions shall be determined by AOL in
          its reasonable editorial discretion. ICP shall comply with the
          programing requirements and provide the Content set forth on Exhibit
          A. AOL's provision of Promotions in connection with any particular AOL
          Property shall be conditioned upon ICP's compliance in all material

          -------
          on the programming plan attached as Exhibit A-2 (the "Programming
          Plan") and shall not contain any pointers or links to any other area
          on or outside the AOL Network, other than as described on Exhibit A
          with respect to such ICP Programming, without AOL's prior written
          consent (not to be unreasonably withheld).  The ICP Internet Site
          shall consist of the Content described on the Programming Plan and any
          other Content as to which the Parties may mutually agree from time to
          time. ICP shall inform AOL of relevant search terms and terminology
          associated with popular areas and functionality within the ICP
          Internet Site and ICP Programming for AOL's promotional and content
          integration purposes.  The inclusion of any additional Content for
          distribution through the AOL Network (including, without limitation,
          any features, functionality or technology) not expressly described on
          Exhibit A shall be subject to AOL's prior written approval.

     1.3  License.  ICP hereby grants AOL a non-exclusive worldwide license to
          -------
          use, market, license, store, distribute, reproduce, display, adapt (to

          determine in its sole discretion, including without limitation the
          right to integrate Content from the ICP Internet Site and/or ICP
          Programming by linking to specific areas thereon, provided that the
          link to any such Content on the AOL Network shall conform to the
          specifications of an ICP Presence. Any Linked ICP Interactive Sites

                 Internet Site, ICP Programming and the Licensed Content in a
                 timely and professional manner and in accordance with the terms

                 to keep the Licensed Content current, accurate and well-
                 organized at all times. ICP shall ensure that the Licensed
                 Content within the ICP Internet Site and ICP Programming is
                 equal to or better than the Content distributed by ICP through
                 any other ICP Interactive Site in all material respects,
                 including without limitation, quality, breadth, timeliness,
                 functionality, features, prices of products

                 and services and terms and conditions, except to the extent
                 inclusion of such Content would other-wise violate this
                 Agreement and except as otherwise expressly stated on Exhibit
                 A. Notwithstanding the foregoing, the Parties acknowledge and
                 agree that the Content available on the Institutional Investor
                 Interactive Site may differ in material respects from the
                 Content offered on the ICP Internet Site; provided, however,
                                                           --------  -------
                 that ICP shall not offer any consumer-oriented Content to any
                 other Interactive Service that is materially different in any
                 respect from any consumer-oriented (e.g., non-institutional
                 investor-oriented) Content offered to AOL Members. Except as
                 specifically provided for herein, AOL shall have no obligations
                 of any kind with respect to the ICP Internet Site or ICP
                 Programming.

          1.4.2  Hosting, Communication and Network Costs.  ICP shall be
                 ----------------------------------------
                 responsible for any hosting or communication costs associated
                 with the ICP Internet Site and ICP Programming (including any
                 Linked Interactive Sites), including, without limitation, the
                 costs associated with (i) any agreed upon direct connections
                 between the AOL Network and the ICP Internet Site or ICP
                 Programming or (ii) a mirrored version of the ICP Internet
                 Site. All AOL network costs associated with the delivery of ICP
                 Content, including multimedia events through the AOL Network,
                 will be covered through the Quarterly Payments. ICP will work
                 with AOL to minimize network costs indirectly or directly
                 incurred as a result of delivering the ICP Content. Upon mutual
                 agreement of the Parties, AOL may host the ICP Internet Site
                 and ICP Programming and ICP shall be responsible for any costs
                 associated with such hosting. In addition, AOL may elect to
                 host certain events, and AOL shall be responsible for any costs
                 associated with such hosting.

          1.4.3  No Registration; Site Access.  Without AOL's prior approval,
                 ----------------------------
                 which will not be unreasonably withheld, AOL Members shall not
                 be required to go through a registration process (or any
                 similar process) in order to access and use the ICP Internet
                 Site, ICP Programming (including any Linked ICP Interactive
                 Site) or the Licensed Content. During the Term and for the two
                 (2) year period after the expiration or termination thereof,
                 ICP shall not prevent AOL Members from accessing and/or using
                 any ICP Interactive Site on terms and conditions that are as

          1.4.4  Failure to Comply with Material Obligations.
                 -------------------------------------------

                 (a)  ICP Technical Problem.  ICP shall ensure that the ICP
                      ---------------------
                      Internet Site complies at all times, in all material
                      respects, with the standards set forth in Exhibit E
                      hereto. In the event of any ICP Technical Problem (as
                      defined in Exhibit B), AOL shall have the right to block
                      AOL Member access to the ICP Internet Site until such time
                      as ICP cures such ICP Technical Problem. In the event that
                      ICP fails to cure any such ICP Technical Problem within
                      [**] business days, ICP shall be deemed to be in
                      breach of the Agreement and the thirty (30) day cure
                      period set forth in Section 6.2 of the Agreement shall
                      begin to toll. AOL shall have the right (in addition to
                      any other remedies available to AOL hereunder (e.g., any
                      blocking right)) to reduce (on a pro rata basis) the
                      Impressions Target until such time as ICP cures such ICP
                      Technical Problem (i.e., for each day such ICP Technical
                      Problem exists beyond such initial [**] business day
                      period, the Impressions Target shall be reduced by [**]
                      of the Impressions to be provided by AOL hereunder), and
                      in such event, AOL shall be relieved of the proportionate
                      amount of the Impressions Target corresponding to such
                      reduction in Impressions.

               (b)    Non-Compliant Content.  In the event that AOL notifies ICP
                      ---------------------
                      of the existence of any Content on the ICP Internet Site
                      that violates the terms or conditions of this Agreement
                      ("Non-Compliant Content"), AOL shall have the right to
                      immediately block AOL Member access to the ICP Internet
                      Site, and ICP shall promptly remove such Content. In the
                      event of the existence of any Non-Compliant Content, AOL
                      shall have the right (in addition to any other remedies
                      available to AOL hereunder (e.g., any blocking right)) to
                      immediately reduce (on a pro rata basis) the Impressions
                      Target until such time as ICP cures such Non-Compliant
                      Content (and in such event, AOL shall be relieved of the
                      proportionate amount of the Impressions Target
                      corresponding to such reduction in Impressions) (i.e., for
                      each day such Non-Compliant Content exists, the
                      Impressions Target shall be reduced by [**] of the
                      Impressions to be provided by AOL hereunder). In the event
                      that ICP fails to cure such Non-Compliant Content within
                      [**] days of receiving notice from AOL, AOL shall
                      have the right to terminate this Agreement.

     1.5  Carriage Fee.
          ------------

          1.5.1  Schedule.  ICP shall pay AOL Fourteen Million One Hundred
                 --------
                 Thousand Dollars ($14,100,000.00) according to the quarterly
                 payment schedule set forth on Schedule 1.5 attached hereto (the
                 "Quarterly Payments"), on the quarterly dates set forth on such
                 Schedule.

          1.5.2  Wired Payments.  All payments by ICP hereunder shall be paid in
                 --------------
                 immediately available, non-refundable U.S. funds wired to the
                 "America Online" account, Account Number [**] at the Chase
                 Manhattan Bank, 1 Chase Manhattan Plaza, New York, New York
                 10081 (ABA: 021000021), or such other account of which AOL
                 shall give ICP written notice.

          1.5.3  Late Payments.  In the event a Quarterly Payment is overdue by
                 -------------
                 fifteen (15) days following notice thereof to ICP, AOL, (i) may
                 reduce the relevant Advertising Revenue Share to be paid to ICP
                 by AOL hereunder up to such amount as is sufficient to offset
                 the overdue payment due AOL, until such amount has been fully
                 offset and (ii) in addition to any other remedies available to
                 AOL hereunder, AOL may terminate this Agreement. Interest on
                 any such overdue payment shall accrue at the Prime Rate plus
                 two percent (2%) per annum.

          1.5.4  Warrants.  ICP shall provide AOL with common stock purchase
                 --------
                 warrants evidencing AOL's right to purchase stock of ICP, on
                 the terms and conditions as specified in the warrant agreement
                 attached hereto as Exhibit G (the "Warrant Agreement"), to be
                 executed concurrently with this Agreement. In the event a
                 Quarterly Payment is overdue by forty-five (45) days following
                 notice thereof to ICP, and a reduction in the relevant
                 Advertising Revenue Share to be paid to ICP by AOL hereunder is
                 not sufficient to offset the overdue payment due AOL, then AOL
                 shall have the right to have such warrants begin vesting
                 immediately at a rate to be calculated as follows: until the
                 earlier of (a) the date on which such overdue payment is made,
                 or (b) the date on which all warrants have fully vested, an
                 additional 5% of the total number of "Acceleration Warrants"
                 shall vest, where "Acceleration Warrants" means such number of
                 warrants as is calculated according to the following formula:

                              AW=1.2 * ( X * WAR)

                 where AW is the number of Acceleration Warrants, X is the total
                 amount of payment due AOL which is then overdue, and WAR is the
                 warrant-to-advertising-revenue ratio then applicable pursuant
                 to the Warrant Agreement (that is, the number of warrants
                 issuable, at the time, under the Warrant Agreement, per dollar
                 of advertising revenue generated by AOL).

          1.5.5  Advertising Payments.  Notwithstanding anything to the contrary
                 --------------------
                 in Schedule 4.2, during the period between the Effective Date
                 and September 1, 2000, [**] of the Advertising Revenue Share
                 (as defined in Section 4.1 below) shall be paid back to AOL by
                 ICP and shall be credited toward ICP's September 1, 2000
                 carriage payment, until the earlier of (a) the date on which
                 the September 1, 2000 carriage payment has been paid in full
                 via such Advertising Revenue Share payments back to AOL, or (b)
                 September 1, 2000 (when ICP shall pay any remaining portion of
                 the September 1, 2000 carriage payment to AOL).

     1.6  Impressions Target.  During the Term, AOL shall provide ICP with [**]
          ------------------
          Impressions from ICP's presence on the AOL Network (the "Impressions
          Target"); provided that AOL shall use commercially reasonable efforts
                    --------
          to deliver the aforementioned Impressions as evenly as practicable
          over each calendar quarter over the course of the Term.  For the
          purposes of this Agreement, ICP's presence on an AOL screen shall
          conform to the specifications of an ICP Presence, provided that only
          screens that contain a link to the ICP Internet Site or ICP
          Programming will count against the Impressions Target.  In the event
          that the Impressions Target is not met (or will not, in AOL's
          reasonable judgment, be met) during the Term, then as ICP's sole
          remedy, at AOL's option either (a) the Term shall be extended for up
          to six (6) months without additional carriage fees payable by ICP, (b)
          AOL shall, from time to time, provide ICP with the remaining
          Impressions in the form of advertising space within the AOL Network of
          comparable value to the undelivered Impressions (as reasonably
          determined by AOL), or (c) some combination thereof.

     1.7  Member Benefits.  ICP will generally promote through the ICP Internet
          ---------------
          Site any special or promotional offers made available by or on behalf
          of ICP through any ICP Interactive Site or any other distribution
          channel; provided, however, that ICP shall not be required to promote
                   --------  -------
          through the ICP Internet Site offers the sole purpose of which is to
          attract or retain public corporations as clients or institutional
          investors as subscribers.  In addition, ICP shall work with AOL to
          promote through the ICP Internet Site on a

          regular basis (but in any event not less than once per quarter)
          special offers exclusively available to AOL Members ("AOL Exclusive
          Offers"). The AOL Exclusive Offers made available by ICP shall provide
          a substantial member benefit to AOL Members, either by virtue of a
          meaningful price discount, product enhancement, unique service benefit
          or other special feature (e.g., a special speaker, etc.). ICP will
          provide AOL with reasonable prior notice of AOL Exclusive Offers and
          other special offers so that AOL can, in its editorial discretion,
          market the availability of such offers.

     1.8  Premier Status.
          --------------

          1.8.1  Generally.  So long as ICP is in compliance with all material
                 ---------
                 terms of this Agreement, during the Term, ICP will be the
                 premier aggregator of IR Information (as defined in Exhibit B)
                 that is promoted by [**] (the "Premier Status"). Such Premier
                 Status shall include, [**] the following:

                 (a)  AOL shall list the ICP Internet Site in AOL's "Directory
                      of Services" and "Find" features;

                 (b)  AOL shall not enter into an agreement during the Term with
                      any ICP Competitor with respect to the provision of
                      additional IR Information on or through the Premier Areas
                      (e.g., related to other companies not currently
                      contemplated by the terms of this Agreement), without also
                      providing ICP with a good-faith opportunity to bid on the
                      provision of such additional IR Information on or through
                      the Premier Areas. AOL shall negotiate in good-faith with
                      ICP with respect to such bid from ICP;

                 (c)  Once the Premier Areas have completed the year 2000
                      redesign, the Personal Finance [**] (when commercially
                      available to AOL Members) and the IR Information link from
                      the primary Quotes page within the Premier Areas shall be
                      [**] (i.e., the majority of AOL Members shall
                      not have to [**] the relevant Promotion).

                 AOL's provision of the Premier Status to ICP is contingent upon
                 ICP's full performance of all material obligations and full
                 compliance with all material conditions set forth in this
                 Agreement, including without limitation, ICP's payment of all
                 fees due and owing by ICP under (and pursuant to the terms of)
                 this Agreement. In the event of any substantial redesign of the
                 AOL Personal Finance Channel during the Term, AOL shall use
                 commercially reasonable

                                      -7-
<PAGE>

                 efforts to ensure that such redesign shall not have a material
                 adverse effect on the Premier Status. Any Dispute regarding
                 whether any such redesign has a material adverse effect on the
                 Premier Status shall be submitted to the Management Committee
                 for final resolution pursuant to Section VII of Exhibit C to
                 this Agreement.

          1.8.2  AOL Right to Terminate ICP Premier Status.
                 -----------------------------------------

                 (a)     AOL shall have the right to terminate the Premier
                         Status upon ICP's failure to fully perform all material
                         obligations or fully comply with all material
                         conditions set forth in this Agreement; and

                 (b)     AOL shall have the right to terminate, in whole or in
                         part, the Premier Status, in the event that at any time
                         during the Term, the ICP Internet Site is not the top
                         ranked Internet site whose principal business is the
                         provision of aggregated investor relations web site
                         content, in terms of, when taken as a whole: (a)
                         quality based upon a cross-section of independent
                         third-party reviewers who are recognized authorities in
                         the investor relations industry and with respect to all
                         material quality averages or standards in the investor
                         relations category, including without limitation,
                         quality, breadth, depth, timeliness, accuracy and
                         reliability of the Content; functionality, features,
                         ease of use and user interface of the site; and prices
                         and terms and conditions of Products offered on the
                         site and (b) both traffic, as measured by page views
                         for IR Information components of third-party Internet
                         Sites, and audience reach, as measured by share or
                         percentage of Internet online users as reported by
                         Media Metrix or similar organization reasonably
                         determined by AOL.

                 1.8.2.1 Permissible AOL Activities. Notwithstanding anything to
                         --------------------------
                         the contrary in Section 1.8.1 above (and without
                         limiting any actions which may be taken by AOL without
                         violation of ICP's rights hereunder), no provision of
                         this Agreement will limit AOL's ability (on or off the
                         AOL Network) to:

                         parties' IR Information in the Premier Areas in a

     2.2  Interactive Site.
          ----------------

          2.2.1  Within each Unrestricted Interactive Site, ICP shall (a) upon
                 receiving further details from AOL, use commercially reasonable
                 efforts to participate in the "Netscape Now Affiliate Program"
                 and (b) include a prominent (i.e., as prominent as that of
                 [**]) promotional button or banner (at least 90 x 30 pixels or
                 70 x 70 pixels in size) appearing on the first screen of the
                 Unrestricted Interactive Site (the "AOL Promo") or, other area
                 of the ICP Interactive Site as mutually agreed upon by the
                 Parties (the consent of either Party to such placement not to
                 be unreasonably withheld), through which users may obtain
                 promotional information about the AOL Service, the CompuServe
                 brand service, Netscape or the AOL Instant Messenger service)
                 and, at AOL's option, download or order the then-current
                 version of client software for such AOL products or services.
                 AOL will provide the creative content to be used in the AOL
                 Promos. ICP shall post (or update, as the case may be) the
                 creative content supplied by AOL within the spaces for the AOL

                                      -9-
<PAGE>

                 Promos within five days of its receipt of such content from
                 AOL. Without limiting any other reporting obligations of the
                 Parties contained herein, ICP shall provide AOL with monthly
                 written reports specifying the number of Impressions to the
                 pages containing the AOL Promos during the prior month. In the
                 event that AOL elects to serve the AOL Promos to an
                 Unrestricted Interactive Site from an ad server controlled by
                 AOL or its agent, ICP shall take all reasonable operational
                 steps necessary to facilitate such ad serving arrangement,
                 including, without limitation, inserting HTML code designated
                 by AOL on the pages of the Unrestricted Interactive Site on
                 which the AOL Promos will appear.

          2.2.2  Within each Unrestricted Interactive Site, ICP shall provide
                 prominent promotion for the keywords associated with the ICP
                 Internet Site, and to the extent ICP offers or promotes any
                 products or services similar to AOL's component products and
                 services (e.g. Netfind or other search/directory services,
                 NetMail or free/discount email, Instant Messenger, yellow/white
                 pages, "My AOL" type personalized information, classifieds,
                 etc.), ICP shall provide equal or greater promotions for such
                 AOL-designated products.

     2.3  Other Media.  In ICP's television, radio, print and "out of home"
          -----------
          (e.g., buses and billboards, point of purchase and other "place-based"
          promotions) advertisements which are directed at a retail consumer
          audience (in contrast to advertisements directed at public companies
          ICP seeks to attract as its clients or at the institutional investor
          community), ICP will include specific references or mentions (orally
          where possible) of the availability of the ICP Internet Site through
          the America Online(R) brand service on terms and conditions to be
          mutually agreed upon by the Parties.  In any event, such references or
          mentions shall be at least as prominent as any references that ICP
          makes to any ICP Interactive Site (by way of site name, related
          company name, URL or otherwise). Without limiting the generality of
          the foregoing, ICP's listing of the "URL" for any ICP Interactive Site
          will be accompanied by an equally prominent listing of the "keyword"
          term on AOL for the ICP Internet Site, which listing shall conform to
          the keyword guidelines attached hereto as Exhibit F.  All such
          references or mentions of AOL, and the use of AOL's trademarks, trade
          names and service marks in connection therewith, shall be in
          accordance with Section II of Exhibit C.

     2.4  Preferred Access Provider.  So long as ICP receives the Premier Status
          -------------------------
          under this Agreement, ICP shall not promote any Interactive Service
          more favorably than AOL, and will not promote any Interactive Service
          other than AOL as its preferred Interactive Service.  In all
          promotions in which ICP references AOL, ICP shall use commercially
          reasonable efforts to promote AOL as its preferred Interactive
          Service.

3.   REPORTING
     ---------

     3.1  AOL Reporting.
          -------------

          3.1.1  Usage.  AOL will supply ICP with monthly reports specifying for
                 -----
                 the prior month aggregate usage and Impressions with respect to
                 ICP's presence on the AOL Network, which are similar in
                 substance and form to the reports provided by AOL to other
                 content partners similar to ICP.

          3.1.2  Advertising.  As quickly as is reasonable at the end of each
                 ----------
                 quarter, AOL will supply ICP with reports specifying the cash
                 value or fair market equivalent value of any AOL Advertisements
                 sold during the prior quarter. The report format, unless
                 otherwise mutually agreed, will be similar in substance and
                 form to the reports provided by AOL to other content partners
                 similar to ICP. Each subsequent quarterly report shall contain
                 an adjustment from, prior quarterly reports for actual amounts
                 collected by AOL from the sale of AOL Advertisements during the
                 previous quarters.

     3.2  ICP Internet Site Reporting.  ICP will supply AOL with monthly reports
          ---------------------------
          that reflect total impressions by AOL Members to the ICP Internet Site
          during the prior month, the number of and aggregate dollar value
          associated with the transactions involving AOL Members (to the extent
          such information is available or applicable) and any registration
          information obtained from AOL Members at the ICP Internet Site during
          the period in question.  ICP represents that all URLs related to the
          ICP Internet Site are listed on Exhibit A-2 and ICP shall provide AOL
          with an update of such list promptly upon any change thereto.

     3.3  Promotional Commitments.  ICP shall provide to AOL a monthly report
          -----------------------
          documenting its compliance with any promotional commitments it has
          undertaken pursuant to this Agreement, and ICP shall provide AOL with
          "click-through" data with respect to the promotions specified in
          Section 2.

4.   ADVERTISING AND MERCHANDISING
     -----------------------------

     4.1  AOL Advertisements.  AOL shall have the right to license or sell
          ------------------
          promotions, advertisements, links, pointers or similar services or
          rights ("Advertisements") in or through the ICP Internet Site and ICP
          Programming ("AOL Advertisements"). AOL shall use commercially
          reasonable efforts to license or sell AOL Advertisements.  AOL shall
          pay ICP a percentage of the Advertising Revenues generated by AOL or
          its agents with respect to AOL Advertisements (the "Advertising
          Revenue Share") according to Schedule 4.2 attached hereto.

         Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission.  Asterisks denote omissions.

     4.2  Advertising Sales.  AOL owns all right, title and interest in and to
          -----------------
          the advertising and promotional spaces within the AOL Network and the
          ICP Internet Site (including, without limitation, advertising and
          promotional spaces on any AOL forms or pages on which ICP Programming
          resides).  The specific advertising inventory within any such pages
          shall be as reasonably determined by AOL. Upon the prior written
          approval of AOL (not to be unreasonably withheld), ICP shall have the
          right to license or sell Advertisements in or through the ICP Internet
          Site and ICP Programming; provided, however, that in the event that
                                    --------  -------
          both AOL and ICP sell or license an Advertisement for a particular
          screen in or through the ICP Internet Site, the AOL Advertisement will
          have priority; provided, further, that ICP will not sell any
                         --------  -------
          Advertisements to any Interactive Service without the prior written
          approval of AOL.  Notwithstanding the foregoing, in the event that
          ICP's share of the Advertising Revenues is less than (a) [**] in the
          first year of the Term, (b) [**] in the aggregate by the end of the
          second year of the Term, or (c) [**] in the aggregate by the end of
          the third year of the Term (each, an "Advertising Revenue Share
          Threshold"), ICP shall have the right, but not the obligation, to sell
          advertising on the ICP Internet Site during the year immediately
          succeeding the year in which ICP's share of the Advertising Revenues
          does not exceed the Advertising Revenue Share Threshold; provided,
                                                                   --------
          however, that after the exercise of such right by ICP, AOL shall not
          -------
          have the obligation to sell any further Advertisements on the ICP
          Internet Site; provided, further, that after  such election by ICP,
                         --------  -------
          ICP shall be required to comply with and honor the terms of any then
          existing contractual commitments between AOL and any third-party
          advertiser with respect to the ICP Internet Site.  In the event that
          in any year of the Term, ICP's share of the Advertising Revenues
          exceeds the Advertising Revenue Share Threshold for such year, AOL
          shall have the right, but not the obligation, to sell advertising on
          the principal ICP Interactive Sites (currently situated at
          www.ccbn.com) pursuant to a revenue sharing arrangement to be mutually
          ------------
          agreed upon by the Parties.  If either ICP or AOL exercises the
          aforementioned rights, the Parties shall coordinate their advertising
          sales efforts to optimize the results of such efforts (e.g., such that
          both Parties' sales forces are not attempting to simultaneously sell
          the same inventory, etc.).

     4.3  Unacceptable Advertisements.  In the event that either Party notifies
          ---------------------------
          the other that it reasonably believes that an Advertisement running on
          the ICP Internet Site or ICP Programming is against its reasonable
          business interests, such Advertisement will be [**].

                                      -12-
<PAGE>

     4.4  Interactive Commerce.  Any merchandising permitted hereunder through
          --------------------
          the ICP Internet Site and/or ICP Programming shall be subject to (i)
          AOL's standard terms and conditions applicable to its interactive
          marketing partners and (ii) prior approval by AOL of all products,
          goods and services to be offered for sale through the ICP Internet
          Site or the ICP Programming.  ICP will take all reasonable steps
          necessary to conform its promotion and sale of Products through the
          ICP Internet Site and ICP Programming to the then-existing
          technologies identified by AOL which are optimized for the AOL Service
          including, without limitation, any "quick checkout" tool which AOL may
          implement to facilitate purchase of Products by AOL Members through
          the ICP Internet Site.  ICP shall not conduct any merchandising
          through the ICP Internet Site or ICP Programming through auctions,
          clubs or any method other than a direct sales format without AOL's
          prior written consent.  Prior to entering into negotiations with any
          third party regarding merchandising or commerce arrangements through
          the ICP Internet Site and/or ICP Programming, ICP shall give AOL
          written notice of such desire and, upon request by AOL, negotiate in
          good faith with AOL or its commerce or marketing partner in the
          applicable product/service category regarding a merchandising or
          commerce arrangement.

     4.5  Payment Schedule.  Except as otherwise specified in Section 1.5, each
          ----------------
          Party agrees to pay the other Party all amounts received and owed to
          such other Party as described in this Section 4, subject to any
          adjustments made as described in Section 3.1.2, on a quarterly basis
          within sixty (60) days of the end of the quarter in which such amounts
          were collected by such Party.  The first quarter for which payment is
          to be made shall (i) begin on the first day of the month following the
          month of execution of this Agreement and (ii) include the portion of
          the month of execution following the Effective Date (unless this
          Agreement was executed on the first day of a month, in which case the
          quarter shall be deemed to begin on the first day of such month).

5.   CUSTOMIZED ICP PROGRAMMING AND ICP INTERNET SITE
     ------------------------------------------------

     5.1  Performance.  All ICP Programming and the ICP Internet Site shall
          -----------
          comply in all material respects with AOL specifications and guidelines
          (including, without limitation, any HTML publishing guidelines) and
          the Operating Standards set forth on Exhibit E attached hereto.

     5.2  Customization.
          -------------

          (a)  ICP shall customize and co-brand the ICP Internet Site for
               distribution over certain AOL Properties as more particularly
               described on Exhibit A-1.  ICP shall make any reasonable changes
               to the customization and/or co-branding requirements of any AOL
               Property that may occur during the Term.

         Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission Asterisks denote omissions.

          (b)  Unless otherwise agreed upon by the Parties, ICP shall ensure
               that AOL Members accessing the ICP Programming or linking to the
               ICP Internet Site do not receive advertisements, promotions or
               links (i) for any entity reasonably construed to be in
               competition with AOL or any AOL Property, (ii) in a category in
               which AOL or the applicable AOL Property has an exclusive or
               other premier relationship with any third party, or (iii)
               otherwise in violation of the applicable AOL Property's standard
               advertising policies, which are subject to change from time to
               time at AOL's reasonable discretion. AOL represents and warrants
               that it has delivered to ICP copies of the current versions -of
               the standard advertising policies for each of the AOL Properties
               which constitute the subject of this Agreement and has notified
               ICP of the categories in which AOL maintains (as of the Effective
               Date) exclusive relationships with any third party commerce
               partner. AOL shall notify ICP of changes to such list of
               categories from time to time, and ICP shall not be deemed to have
               breached the terms of this Section 5.2(b) with respect to
               advertisements, promotions or links in categories with respect to
               which AOL has not notified ICP of an exclusive relationship with
               a third party, so long as (i) such exclusive relationship was in
               full force and effect prior to the inclusion of such promotions,
               advertisements or links and (ii) CCBN removes any such
               promotions, links or advertisements within five (5) days
               following notification by AOL that an exclusive relationship with
               a third party exists. AOL shall use commercially reasonable
               efforts to ensure that ICP will not, by reason of this Section
               5.2(b), be [**] through the ICP Internet Site and ICP
               Programming, provided that the Parties agree that AOL does not
               guarantee that ICP will [**] through the ICP Internet Site and/or
               ICP Programming.

          (c)  ICP shall provide continuous navigational ability for AOL Members
               to return to an agreed-upon point on the applicable AOL Property
               (for which AOL shall supply the proper address) from ICP Internet
               Site or ICP Programming (e.g., the point on the applicable AOL
               Property from which such site is linked), which, at AOL's option,
               may be satisfied through the use of a hybrid browser format.  ICP
               shall ensure that navigation back to the AOL Network from the ICP
               Internet Site, whether through a particular pointer or link, the
               "back" button on an Internet browser, the closing of an active
               window, or any other return mechanism, shall not be interrupted
               by ICP through the use of any intermediate screen or other device
               not specifically requested by the user, including without
               limitation through the use of any html pop-up window or any other
               similar device.  Rather, such AOL traffic shall be pointed
               directly back to the AOL Network as designated by AOL.

          (d)  ICP shall use AOL's tools and technology for all community-
               related utilities and functionality (including, without
               limitation, chat, message boards, and web page community services
               such as AOL Hometown) within ICP Programming and the ICP Internet
               Site and any registration or similar processes permitted
               hereunder in the event that (1) ICP desires to incorporate any
               such types of tools and functionality into the ICP Internet Site
               and/or the ICP Programming and (2) the relevant AOL tools and
               technology are [**]with those [**]. The Parties hereby
               acknowledge and agree that in no event shall the ICP Internet
               Site or ICP Programming contain the tools and technology of any
               AOL competitor without the express written consent of AOL.

     5.3  Links on ICP Internet Site.  The Parties will work together on
          --------------------------
          mutually acceptable links (including links back to AOL) within the ICP
          Internet Site in order to create a robust and engaging AOL member
          experience.  ICP shall take reasonable efforts to ensure that AOL
          traffic is generally either kept within the ICP Internet Site or ICP
          Programming or channeled back into the AOL Network.  To the extent
          that AOL notifies ICP in writing that, in AOL's reasonable judgment,
          links from the ICP Internet Site or ICP Programming cause an excessive
          amount of AOL traffic to be diverted outside of such site and the AOL
          Network in a manner that has a detrimental effect on the traffic flow
          of the AOL audience, then ICP shall immediately reduce (but in no
          event later than five (5) days following notice by AOL) the number of
          links out of such site(s).  In the event that ICP cannot or does not
          so limit diverted traffic from such site, AOL reserves the right to
          terminate such links from the AOL Network to such site; provided that
                                                                  --------
          AOL will not require ICP to remove any such links to areas outside of
          the ICP Internet Site that are necessary for ICP to comply with its
          ICP Programming obligations under this Agreement.

     5.4  Review.  ICP shall allow appropriate AOL personnel to have access to
          ------
          all ICP Programming and the ICP Internet Site for the purpose of
          reviewing such sites to determine compliance with the provisions of
          this Section 5.

6.   TERM, TERMINATION, SITE AND CONTENT PREPARATION, PRESS RELEASES.
     ---------------------------------------------------------------

     6.1  Term.  Unless earlier terminated as set forth herein, the initial term
          ----
          of this Agreement shall commence on the Effective Date and expire
          forty (40) months from the Effective Date. In the event that ICP's
          share of the [**] under this Agreement [**] during the Term, AOL shall
          have the right to extend this Agreement for a term of (at its option)
          one (1) or two (2) additional years terms (the "Extension Term") by
          providing ICP with written notice of such election no later than [**]
          prior to the expiration of the Initial Term (the "Extension
          Notification Period"). Upon receiving such notification, [**] shall
          have [**] to elect whether (a) such Extension Term shall be on the
          same terms and conditions contained herein, in which case ICP shall
          make quarterly payments to AOL of [**] on the first day of each
          calendar quarter of the Extension Term, commencing on the first day of
          the Extension Term or (b) such Extension Term shall be without the
          Premier Status, without any further [**] (other than any [**]
          expressly required by the terms of this Agreement), and without having
          any further obligations under Section 1.7 or Section 2 of this
          Agreement (collectively, the [**] Extension Decision"). Following
          notification by [**] of the [**] Extension Decision, if AOL has
          elected to extend the Agreement for a two (2) year Extension Term, it
          shall have the option to reduce the length of such Extension Term to
          one year by written notification of such decision to CCBN within [**]
          of the [**] Extension Decision. During any Extension Term, AOL shall
          be entitled to receive [**] of the Advertising Revenues generated
          during such Extension Term. Notwithstanding the foregoing, upon the
          expiration or earlier termination of this Agreement, AOL may, at its
          discretion, continue to promote one or more "pointers" or links from
          the AOL Network to an ICP Interactive Site and continue to use ICP's
          trade names, trademarks and service marks in connection therewith.

     6.2  Termination for Breach.  Either Party may terminate this Agreement at
          ----------------------
          any time in the event of a material breach by the other Party which
          remains uncured after thirty (30) days written notice thereof;
          provided, however, that in the event of the existence of a technical
          --------  -------
          problem of either Party beyond the reasonable control of such party (a
          "Force Majeure Event"), the breaching Party shall have sixty (60) days
          to cure such Force Majuere Event before the non-breaching Party shall
          have the right to terminate this Agreement; provide, however, that
          the breaching party shall use commercially reasonable efforts to cure
          such Force Majeure Event as promptly as possible; provided, further,
                                                            --------  -------
          that in the event of an ICP Force Majeure Event, AOL shall have the

          Members with access to (and promote, market or distribute) the IR
          Information of any third party (including, without limitation, any ICP
          Competitor) on or through the Premier Areas.

     6.3  Termination for Bankruptcy/Insolvency or Changes in Business.  Either
          ------------------------------------------------------------
          Party may terminate this Agreement immediately following written
          notice to the other Party if the other Party (i) ceases to do business
          in the normal course, (ii) becomes or is declared insolvent or
          bankrupt, (iii) is the subject of any proceeding related to its
          liquidation or insolvency (whether voluntary or involuntary) which is

                      completed all other necessary work (including, without
                      limitation, all AOL site testing set forth on Exhibit E)
                      to prepare the ICP Internet Site, all ICP Programming and
                      any other related areas or screens to launch on the AOL
                      Network as contemplated in Exhibit A-2.

                 (b)  As used herein, "[**] Preparation" shall mean
                      that ICP shall have completed all necessary production
                      work for the ICP Internet Site, all ICP Programming and
                      any other related areas or screens (including programming
                      all Content thereon) in accordance with subpart II-B of
                      Exhibit A-2.

                 (c)  As used herein, "AOL Failure" means, with respect to
                      either the Site and Content Preparation Date or the [**]
                      Deadline Date, AOL's failure: (i) to make [**] available
                      by such date, (ii) to develop a data retrieval/integration
                      mechanism appropriate and sufficient to allow ICP to
                      achieve Site and Content Preparation or [**] Preparation,
                      as applicable, (iii) to provide ICP the necessary
                      technical specifications to allow it to achieve Site and

                      (v) to perform its obligations under this agreement.

          6.4.2  ICP shall achieve Site and Content Preparation within ninety
                 (90) days after the Effective Date (the "Site Deadline Date")
                 and shall achieve [**] Preparation no later than
                 [**] (the "[**] Deadline Date");

          6.4.3  If ICP has not achieved [**] Preparation by the
                 [**] Deadline (either by providing the necessary
                 content itself or procuring it from alternative sources),
                 unless such failure is solely due to an AOL Failure, AOL may
                 procure the content necessary to allow it to operate its
                 Personal Finance [**] directly from third party sources. If
                 such failure is solely due to an AOL Failure, the [**]
                 Deadline shall be extended by the number of days solely
                 attributed to such AOL Failure.

          6.4.4  In the event ICP has not achieved Site and Content Preparation
                 within [**] after the Effective Date, then the Impressions
                 Target set forth in Section 1.6 shall be reduced on a pro rata
                 basis based on the number of days after such [**] period
                 that ICP achieves Site and Content Preparation divided by 1183.
                 In the event ICP has not achieved Site and Content Preparation
                 within [**]after the Effective Date, then in addition to any
                 other remedies available, AOL shall have the right to terminate
                 this Agreement by giving ICP written notice thereof. If ICP is
                 delayed in achieving Site and Content Preparation due to an AOL
                 Failure and ICP notifies AOL in writing of such failure and the
                 resulting delay, then the [**] and [**] periods referenced
                 in this Section shall each be extended by the amount of time of
                 ICP's delay solely attributable to such failure by AOL, and AOL
                 shall [**] for such delay unless and until such applicable
                 period, as so extended, expires without ICP having achieved
                 Site and Content Preparation.

     6.5  Press Releases.  Each Party will submit to the other Party, for its
          --------------
          prior written approval, which will not be unreasonably withheld or
          delayed any press release or any other public statement ("Press
          Release") regarding the transactions contemplated hereunder.  The
          failure to obtain the prior written approval of the other Party shall
          be deemed a material breach of this Agreement, whereby the non-
          breaching Party may terminate this Agreement immediately following
          written notice to the other Party, and the cure provision of Section
          6.2 of this Agreement shall not apply. Notwithstanding the foregoing,
          either Party may issue Press Releases and other disclosures as
          required by law or as reasonably advised by legal counsel without the
          consent of the other Party

                                     -18-

          and in such event, the disclosing Party will provide at least five (5)
          business days prior written notice of such disclosure.

depth, accuracy and technical compatibility), AOL may use a third party for such
IR information.

All pages and content provided by ICP must conform to established design
guidelines and technical specifications for the Investment Research area.

All placements will be integrated according to a mutually agreed to roll-out
schedule.

AOL may use third party providers of IR Information in the event that CCBN is
unable to meet the deadlines set forth herein and/or the relevant product
specifications.

II.  Links to ICP Programming
     ------------------------

     On its Investment [**] and Investment Research Site (and on each future
site which is a specific successor to one of such sites), AOL shall provide a
contextual, non-branded link to the ICP Site as is farther described as the CCBN
"IR Hub."

     On AOL's Investment Snapshots and in its Portfolio Direct (and on each
future site which is a specific successor to one of such sites), AOL will
provide an indexed link to each company-specific "home page" within the CCBN IR
Hub.

     From time to time, in its discretion, when companies likely to be of
interest to a large audience are participating in upcoming conference calls
either available or coordinated by ICP, AOL may promote such calls as "Live
Events" on both the Personal Finance Main Screen and in the AOL Live area.  Such
guests will be promoted on AOL Live with a brief write-up and with a picture (if
available) and will be branded with "brought to you by StreetEvents" or a
similar, mutually agreed-upon branded promotion of ICP.  While not required, ICP
would hope that AOL shall promote ICP-sponsored events pursuant to this
paragraph on no fewer than [**] occasions in each calendar month during the
Term of this Agreement.

                                  EXHIBIT A-2

                    ICP Programming and Content Obligations
                    ---------------------------------------

I.  General Content
    ---------------

     ICP will provide AOL with access to a number of products and services
including links to company investor relations Sites, access to live and archived
investor conference calls, and access to company event information.  ICP's
overall objective is to provide AOL Members access to a critical mass of
company-specific, investor-oriented information, as well as to lay the
groundwork for an important forum for companies to communicate directly with the
AOL community.  This will be achieved in both an aggregated and disaggregated
(e.g., ticker-based indexed links to events and information) manner.

     ICP will make available over the AOL Service, and over other AOL Properties
(as more fully described in Section III below) the ICP Internet Site and the ICP
Programming described in Sections II and III below.

     II.  ICP Internet Site and ICP Programming
          -------------------------------------

     ICP will create a customized site to be carried on the AOL Service, under a
domain name co-branded with AOL (e.g.,ccbn.aol.com), tentatively to be called
the "IR Hub".  The CCBN-Street Events "IR Hub" site will be the Service's
primary offering for all things related to the investor relations function of
publicly traded companies.  The IR Hub developed and maintained by CCBN will
initially have the following as its principal components: a wide variety of live
and recorded company conference calls, event information for such corporate news
as earnings release dates and times, access to company IR web sites, and other
important IR related material -- and may in the future have additional
components appropriate to ICP's current or future business.

     The specific design of the IR Hub will be mutually agreed to by the
Parties, provided that the IR Hub shall include the Content described in this
Exhibit A-2 and shall conform to the applicable AOL Property's then-standard co-
branding guidelines for Investment Research, Personal Finance and [**]
partners.

ICP will create the assets described below:

A.   Site Assets
- ----------------

     1)   Co-branded IR Hub

The central, unified offering of all IR-related material on the Service.  This
Hub will contain (as an example) navigation which will allow members to find IR
information on companies of interest, lists of important upcoming events
(calls), lists of important recent events (recorded calls), and other supporting
information.

<PAGE>

         Confidential materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omission.

     2)   IR Pages

These will be ticker-based pages that will be linked to from various company
specific sites and pages (most importantly the AOL Quote and other company
research functions).  ICP will endeavor to provide the following, at a minimum:

     For Companies that are a part of the following indexes or lists: S&P 500,
     AOL Top 100 most popular portfolio symbols, Nasdaq 100, and TheStreet.com
     Internet Index (the DOT).

     .    [**] access to all [**] must be
     .    [**] access to [**] information for [**]
     .    [**] to the Company's [**]
     .    [**] info for [**]
     .    The established [**] Company [**] etc.)
     .    Button/Link so that a user can [**] to the
          [**]

For Companies that are outside the indexes and lists above:

     .    [**] (both [**])from [**] (if available)
     .    [**] Company's [**] (if available)
     .    Basic contact info for IR Department
     .    The established [**] Company
          company [**] etc.)
     .    [**] so that a user can [**]
          (when possible)

     ICP reserves the right to add or delete specific information to or from
each Company Site during the term of the Agreement, as long as it is in keeping
with this basic array of information.

     3)   A system for contextual newsfeed publication.

This system will permit AOL to publish recently recorded conference calls and
other IR news-related events within its contextual newsfeed displays.  This
system should permit AOL to update its displays in [**]
as possible - and at a minimum will be updated once a day.

ICP shall create the following assets by the [**] Deadline Date,
subject to the limitations as described in Section 6.4:

     1)   A Co-branded, centralized Personal Finance [**]

     This will be a co-branded, AOL/StreetEvents centralized Personal Finance
     [**]that includes access to [**] information for companies including [**]
     subjects, [**] as well as non-company specific [**].

          The [**] will include the following features:

          .    [**], which includes [**] for the [**] for each of the [**]
               based on a [**]. Companies that should be [**]
               the companies [**]

               [**], with relevant information based on [**]


          .    [**] - Ability to [**] for [**] by [**]

          .    [**] - ability to [**]for [**] by [**] (both
               [**]).

          .    From [**] the [**] pages, provide [**] to respective [**]
               that [**]. For example, a [**] will have a [**] to a page that
               [**] and provides audio access, if available. [**] will include
               [**]. Examples include:

          .    [**] will [**] to [**]

          .    [**] will go to [**]

attempt to register or otherwise obtain trademark or copyright protection in the

and for a period of three years following expiration or termination of this
Agreement to prevent the disclosure of Confidential Information of the other
Party, other than to its employees, or to its other agents who must have access
to such Confidential Information for such Party to perform its obligations
hereunder, and who are under obligations of confidentiality appropriate to
protect the interests of the Parties hereunder (including, without limitation,
the obligations set forth in this section).  Notwithstanding the foregoing,
either Party may issue a press release or other disclosure containing
Confidential Information without the consent of the other Party, to the extent

order.  In such event, the disclosing Party will provide at least five (5)
business days prior written notice of such proposed disclosure to the other
Party.  Further, in the event such disclosure is required of either Party under

extent permitted under the laws, rules or regulations of any other applicable
governing body.  Also notwithstanding the foregoing, either Party may disclose
Confidential Information to its current or bona fide prospective investors,
investment bankers, lenders, accountants and attorneys, in each case only where
such persons or entities are under obligations of confidentiality appropriate to

the obligations set forth in this section).

V.  RELATIONSHIP WITH AOL MEMBERS

Solicitation of Subscribers.  (a) During the term of this Agreement and for a
- ---------------------------
two year period thereafter, ICP will not use the AOL Network (including, without
limitation, the e-mail network contained therein) to solicit AOL Members on
behalf of another Interactive Service.  More generally, ICP will not send
unsolicited, commercial e-mail (i.e., "spam") or other online communications
through or into AOL's products or services, absent a Prior Business
Relationship. For purposes of this Agreement, a "Prior Business Relationship"
will mean that the AOL Member to whom commercial e-mail or other online
communication is being sent has voluntarily either (i) engaged in a transaction
with ICP or (ii) provided information to ICP through a contest, registration, or
other communication, which included clear notice to the AOL Member that the
information provided could result in commercial e-mail or other online
communications being sent to that AOL Member by ICP or its agents.  Any
commercial e-mail or other online communications to AOL Members which are
otherwise permitted hereunder will (a) include a prominent and easy means to
"opt-out" of receiving any future commercial e-mail communications from ICP and
(b) shall also be subject to AOL's then-standard restrictions on distribution of
bulk e-mail (e.g., related to the time and manner in which such e-mail can be
distributed through or into the AOL product or service in question).

(b) ICP shall ensure that its collection, use and disclosure of information
obtained from AOL Members under this Agreement ("Member Information") complies
with (i) all applicable laws and regulations and (ii) AOL's standard privacy
policies, available on the AOL Service at the keyword term "Privacy" (or, in the
case of the ICP Internet Site, ICP's standard privacy policies so long as such
policies are prominently published on the site and provide adequate notice,
disclosure and choice to users regarding ICP's collection, use and disclosure of
user information).  ICP will not disclose Member Information collected hereunder
to any third party in a manner that identifies AOL Members as end users of an
AOL product or service or use Member Information collected under this Agreement
to market another interactive Service.

Email Newsletters.  Any email newsletters sent to AOL Members by ICP or its
- -----------------
agents over the AOL Network shall (i)

                                      -34-
<PAGE>

be subject to AOL's policies on use of the email functionality, including but
not limited to AOL's policy on unsolicited bulk email, (ii) be sent only to AOL
Members requesting to receive such newsletters, (iii) not contain Content which
violates AOL's Terms of Service, and (iv) not contain any advertisements,
marketing or promotion for any other Interactive Service.

AOL Member Communications.  To the extent ICP is otherwise permitted to send
- -------------------------
communications to AOL Members (in accordance with the other requirements
contained herein): in any such communications to AOL Members on or off the ICP
Internet Site (including, without limitation, e-mail solicitations), ICP will
limit the subject matter of such communications to those categories of products,
services and/or content that are specifically contemplated by this Agreement and
will not encourage AOL Members to take any action inconsistent with the scope
and purpose of this Agreement, including without limitation, the following
actions: (i) using an Interactive Site other than the ICP Internet Site for the
purchase of Products, (ii) using Content other than the Licensed Content; (iii)
bookmarking of Interactive Sites; or (iv) changing the default home page on the
AOL browser.  Additionally, with respect to such AOL Member communications, in

communications, ICP shall ensure that (a) the AOL Network is expressly promoted
as the primary means through which the AOL Member can access the ICP Internet
Site (including without limitation by stating the applicable Keyword Search Term
and including direct links to specific offers within the ICP Internet Site) and
(b) any link to the ICP Internet Site will link to a page which indicates to the
AOL Member that such user is in a site which is affiliated with the AOL Network

VI.  TREATMENT OF CLAIMS

Liability.  UNDER NO CIRCUMSTANCES SHALL EITHER PARTY BE LIABLE TO THE OTHER
- ---------
PARTY FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR EXEMPLARY DAMAGES
(EVEN IF THAT PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES),
ARISING FROM BREACH OF THIS AGREEMENT, THE USE OF OR INABILITY TO USE THE AOL
NETWORK THE ICP INTERNET SITE, ANY ICP PROGRAMMING OR ANY LICENSED CONTENT OR
ANY OTHER PROVISION OF THIS AGREEMENT, SUCH AS, BUT NOT LIMITED TO, LOSS OF

REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, REGARDING THE AOL NETWORK,
THE ICP INTERNET SITE, THE ICP PROGRAMMING, ANY LICENSED CONTENT OR ANY AOL

- ---------
Party and the officers, directors, agents, affiliates, distributors, franchisees
and employees of the other Party from any and all third party claims, demands,
liabilities, costs or expenses, including reasonable attorneys' fees
("Liabilities"), resulting from the indemnifying Party's material breach of any
duty, representation, or warranty of this Agreement.  In addition, ICP will
defend, indemnify, save and hold harmless AOL and AOL's officers, directors,
agents, affiliates, distributors, franchisees and employees from any and all
Liabilities arising out of or in any way related to the Licensed Content.

If a Party entitled to indemnification hereunder (the "Indemnified Party")
becomes aware of any matter it believes is indemnifiable hereunder involving any
claim, action, suit, investigation, arbitration or other proceeding against the
Indemnified Party by any third party (each an "Action"), the Indemnified Party
shall give the other Party (the "Indemnifying Party") prompt written notice of
such Action. Such notice shall (i) provide the basis on which indemnification is
being asserted and (ii) be accompanied by copies of all relevant pleadings,
demands, and other papers related to the Action and in the possession of the
Indemnified Party- The Indemnifying Party shall have a period of ten (10) days
after delivery of such notice to respond.  If the Indemnifying Party elects to
defend the Action or does not respond within the requisite ten (10) day period,
the Indemnifying Party shall be obligated to defend the Action, at its own
expense, and by counsel reasonably satisfactory to the Indemnified Party.  The
Indemnified Party shall cooperate, at the expense of the Indemnifying Party,
with the Indemnifying Party and its counsel in the defense and the Indemnified
Party shall have the right to participate fully, at its own expense, in the
defense of such Action. If the Indemnifying Party responds within the required
ten (10) day period and elects not to defend such Action, the Indemnified Party
shall be free, without prejudice to any of the Indemnified Party's rights
hereunder, to compromise or defend (and control the defense of) such Action.  In
such case, the Indemnifying Party shall cooperate, at its own expense, with the
Indemnified

                                      -35-
<PAGE>

Party and its counsel in the defense against such Action and the Indemnifing
Party shall have the right to participate fully, at its own expense, in the
defense of such Action. Any compromise or settlement of an Action shall require
the prior written consent of both Parties hereunder, such consent not to be
unreasonably withheld or delayed.

Acknowledgment.  AOL AND ICP EACH ACKNOWLEDGES THAT THE PROVISIONS OF THIS
- --------------
AGREEMENT WERE NEGOTIATED TO REFLECT AN INFORMED, VOLUNTARY ALLOCATION BETWEEN
THEM OF ALL RISKS (BOTH KNOWN AND UNKNOWN) ASSOCIATED WITH THE TRANSACTIONS
CONTEMPLATED HEREUNDER- THE LIMITATIONS AND DISCLAIMERS RELATED TO WARRANTIES
AND LIABILITY CONTAINED IN THIS AGREEMENT ARE INTENDED TO LIMIT THE
CIRCUMSTANCES AND EXTENT OF LIABILITY.  THE PROVISIONS OF THIS SECTION VI SHALL
BE ENFORCEABLE INDEPENDENT OF AND SEVERABLE FROM ANY OTHER ENFORCEABLE OR
UNENFORCEABLE PROVISION OF THIS AGREEMENT.

VII. ARBITRATION

(a) The Parties shall act in good faith and use commercially reasonable efforts
to promptly resolve any claim, dispute, claim, controversy or disagreement (each
a "Dispute") between the Parties or any of their respective subsidiaries,
affiliates, successors and assigns under or related to this Agreement or any
document executed pursuant to this Agreement or any of the transactions
contemplated hereby.  If the Parties cannot resolve the Dispute within such
timeframe, the Dispute shall be submitted to the Management Committee for
resolution.  For ten (10) days after the Dispute was submitted to the Management
Committee, the Management Committee shall have the exclusive right to resolve
such Dispute; provided further that the Management Committee shall have the
final and exclusive right to resolve Disputes arising from any provision of this
Agreement which expressly or implicitly provides for the Parties to reach mutual
agreement as to certain terms.  If the Management Committee is unable to
amicably resolve the Dispute during the ten (10) day period, then the Management
Committee will consider in good faith the possibility of retaining a third party
mediator to facilitate resolution of the Dispute.  In the event the Management
Committee elects not to retain a mediator, the Dispute will be subject to the
resolution mechanisms described below.  "Management Committee" shall mean a
committee made up of a senior executive from each of the Parties for the purpose
of resolving Disputes under this Section and generally overseeing the
relationship between the Parties contemplated by this Agreement.  Neither Party
shall seek, nor shall be entitled to seek, binding outside resolution of the
Dispute unless and until the Parties have been unable to amicably resolve the
dispute as set forth in this paragraph (a) and then, only in compliance with the
procedures set forth in this Section.

(b) Except for Disputes relating to issues of proprietary rights, including but
not limited to intellectual property and confidentiality, any Dispute not
resolved by amicable resolution as set forth in paragraph (a) shall be governed
exclusively and finally by arbitration. Such arbitration shall be conducted by
the American Arbitration Association ("AAA") in Washington, D.C.  and shall be
initiated and conducted in accordance with the Commercial Arbitration Rules
("Commercial Rules") of the AAA, including the AAA Supplementary Procedures for
Large Complex Commercial Disputes ("Complex Procedures"), as such rules shall be
in effect on the date of delivery of a demand for arbitration ("Demand"), except
to the extent that such rules are inconsistent with the provisions set forth
herein.  Notwithstanding the foregoing, the Parties may agree in good faith that
the Complex Procedures shall not apply in order to promote the efficient
arbitration of Disputes where the nature of the Dispute, including without
limitation the amount in controversy, does not justify the application of such
procedures.

(c) The arbitration panel shall consist of three arbitrators.  Each Party shall
name an arbitrator within ten (10) days after the delivery of the Demand.  The
two arbitrators named by the Parties may have prior relationships with the
naming Party, which in a judicial setting would be considered a conflict of
interest.  The third arbitrator, selected by the first two, shall be a neutral
participant, with no prior working relationship with either Party.  If the two
arbitrators are unable to select a third arbitrator within ten (10) days, a
third neutral arbitrator will be appointed by the AAA from the panel of
commercial arbitrators of any of the AAA Large and Complex Resolution Programs.
If a vacancy in the arbitration panel occurs after the hearings have commenced,
the remaining arbitrator or arbitrators may not continue with the hearing and
determination of the controversy, unless the Parties agree otherwise.

(d) The Federal Arbitration Act, 9 U.S.C. Secs. 1-16, and not state law, shall
govern the arbitrability of all Disputes.  The arbitrators shall allow such
discovery as is appropriate to the purposes of arbitration in accomplishing a
fair, speedy and cost- effective resolution of the Disputes.  The arbitrators
shall reference the Federal Rules of Civil Procedure then in effect in setting
the scope and timing of discovery.  The Federal Rules of Evidence shall apply in
                                                                              --
toto.  The arbitrators may enter a default decision against any Party who fails
- ----
to participate in the arbitration proceedings.

(e) The arbitrators shall have the authority to award compensatory damages only.
Any award by the arbitrators shall be accompanied by a written opinion setting
forth the findings of fact and conclusions of law relied upon in reaching the
decision.  The award rendered by the arbitrators shall be final, binding and
non-appealable, and judgment upon such award may be entered by any court of
competent jurisdiction. The Parties agree that the existence, conduct and
content of any arbitration shall be considered Confidential Information under
this Agreement.

(f) Each Party shall pay the fees of its own attorneys, expenses of witnesses
and all other expenses and costs in connection with the presentation of such
Party's case (collectively, "Attorneys' Fees"). The remaining costs of the
arbitration, including without limitation, fees of the arbitrators, costs of
records or

                                      -36-
<PAGE>

         Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission. Asterisks denote omissions.

transcripts and administrative fees (collectively, "Arbitration Costs') shall be
born equally by the parties. Notwithstanding the foregoing, the arbitrators may
modify the allocation of Arbitration Costs and award Attorneys' Fees in those
cases where fairness dictates a different allocation of Arbitration Costs
between the Parties and an award of Attorneys' Fees to the prevailing Party as
determined by the arbitrators.

(g) Any Dispute that is not subject to final resolution by the Management
Committee or to arbitration under this Section or law (collectively, "Non-
Arbitration Claims") shall be brought in a court of competent jurisdiction in
the Commonwealth of Virginia.  Each Party irrevocably consents to the exclusive
jurisdiction of the courts of the Commonwealth of Virginia and the federal
courts situated in the Commonwealth of Virginia, over any and all Non-
Arbitration Claims and any and all actions to enforce such claims or to recover
damages or other relief in connection with such claims or to enforce a judgment
rendered in an arbitration proceeding.

VIII.  MISCELLANEOUS

- ---------------
of all expenses, revenues, fees, transactions and related documentation

twelve months.  No such audit of AOL shall occur during the period beginning on
June 1 and ending October 1.  In lieu of providing access to its Records as
described above, either party shall be entitled to provide the other with a
report from an independent certified public accounting firm confirming the
information to be derived from such Records.

Excuse.  Neither Party shall be liable for, or be considered in breach of or
- ------
default under this Agreement on account of, any delay or failure to perform as

beyond such Party's reasonable control and which such Party is unable to
overcome by the exercise of reasonable diligence.

Independent Contractors.  The Parties to this Agreement are independent
- -----------------------

Party.  Neither Party shall have any right, power or authority to enter into any
agreement for or on behalf of, or incur any obligation or liability of, or to

construed to create an association, agency, joint venture or partnership between
the Parties or to impose any liability attributable to such a relationship upon
either Party.

other pursuant to this paragraph.

No Waiver.  The failure of either Party to insist upon or enforce strict
- ---------
performance by the other Party of any provision of this Agreement or to exercise
any right under this Agreement shall not be construed as a waiver or

                                   EXHIBIT D
                                   ---------

                            [INTENTIONALLY OMITTED]

                                   ---------

                              OPERATING STANDARDS
                              -------------------

1.   ICP Internet Site Infrastructure.  ICP will be responsible for all
     --------------------------------
     communications, hosting and connectivity costs and expenses associated with
     the ICP Internet Site.  ICP will provide all hardware, software,
     telecommunications lines and other infrastructure necessary to meet traffic
     demands on the ICP Internet Site from the AOL Network.  ICP will design and
     implement the network between the AOL Service and ICP Internet Site such
     that (i) no single component failure will have a materially adverse impact
     on AOL Members seeking to reach the ICP Internet Site from the AOL Network
     and (ii) no single line under ICP's reasonable control will run at more
     than 70% average utilization for a 5-minute peak in a daily period.  In
     this regard, ICP will provide AOL, upon request, with a detailed network
     diagram regarding the architecture and network infrastructure supporting
     the ICP Internet Site.  In the event that ICP elects to create a custom
     version of the ICP Internet Site in order to comply with the terms of this
     Agreement, ICP will bear responsibility for all aspects of the
     implementation, management and cost of such customized site.

2.   Optimization; Speed.  ICP will use commercially reasonable efforts to
     -------------------
     ensure that: (a) the functionality and features within the ICP Internet
     Site arc appropriate for the client software then in use by AOL Members;
     and (b) the ICP Internet Site is designed and populated in a manner that is
     reasonably likely to minimize delays when AOL Members attempt to access
     such site.  At a minimum, ICP will use commercially reasonable efforts to
     ensure that the ICP Internet Site's data transfers initiate within fewer
     than fifteen (15) seconds on average.  Prior to commercial launch of any
     material promotions described herein, ICP will permit AOL to conduct
     performance and load testing of the ICP Internet Site (in person or through
     remote communications), with such commercial launch not to commence until
     such time as AOL is reasonably satisfied with the results of any such
     testing.

3.   Technical Problems.  ICP agrees to use commercially reasonable efforts to
     ------------------
     address material technical problems (over which ICP exercises control)
     affecting use by AOL Members of the ICP Internet Site (an "ICP Technical
     Problem") promptly following notice thereof.  In the event that ICP is
     unable to promptly resolve an ICP Technical Problem following notice
     thereof from AOL (including, without limitation, infrastructure
     deficiencies producing user delays), AOL will have the fight to regulate
     the promotions it provides to ICP hereunder until such time as ICP corrects
     the ICP Technical Problem at issue.

4.   Monitoring.  ICP will ensure that the performance and availability of the
     ----------
     ICP Internet Site is monitored on a continuous (24 X 7) basis.  ICP will
     provide AOL with contact information (including e-mail, phone, pager and
     fax information, as applicable, for both during and after business hours)
     for ICP's principal business and technical representatives, for use in
     cases when issues or problems arise with respect to the ICP Internet Site.

                                      -40-
<PAGE>

5.   Security.  ICP will utilize Internet standard encryption technologies
     --------
     (e.g., Secure Socket Layer - SSL) that are intended to provide a secure
     environment for conducting transactions and/or transferring private member
     information (e.g. credit card numbers, banking/financial information, and
     member address information) to and from the ICP Internet Site.  ICP will
     facilitate periodic reviews of the ICP Internet Site by AOL in order to
     evaluate the security risks of such site.  ICP will use commercially
     reasonable efforts to promptly remedy any security risks or breaches of
     security as may be identified by AOL's Operations Security team.

6.   Technical Performance.
     ---------------------

     i.   ICP will design the ICP Internet Site to support the AOL-Client
          embedded versions of the Microsoft Internet Explorer 3.XX and 4.XX
          browsers (Windows and Macintosh), the Netscape Browser 4.XX and make
          commercially reasonable efforts to support all other AOL browsers
          listed at: "http://webmaster.info.aol.com."
                     --------------------------------

     ii.  To the extent ICP creates customized pages on the ICP Internet Site
          for AOL Members, ICP develop and employ a methodology to detect AOL
          Members (e.g., examine the HTTP User-Agent field in order to identify
          the "AOL Member-Agents" listed at: "http://webmaster.info.aol.com" and
                                             -------------------------------
          referenced under the heading "Browser Detection."

     iii  ICP will periodically review the technical information made available
          by AOL at http://webmaster.info.aol.com.
                    ------------------------------

     iv.  ICP will design its site to support HTTP 1.0 or later protocol as
          defined in RFC 1945 and to adhere to AOL's parameters for refreshing
          or preventing the caching of information in AOL's proxy system as
          outlined in the document provided at the following URL:
          http://webmaster.info.aol.com.  ICP is responsible for the
          manipulation of these parameters in web based objects so as allow them
          to be cached or not cached as outlined in RFC 1945.

     v.   Prior to releasing materially new functionality or features through
          the ICP Internet Site ("New Functionality"), ICP will use commercially
          reasonable efforts to (i) test the New Functionality to confirm its
          compatibility with AOL Service client software and (ii) provide AOL
          with written notice of the New Functionality so that AOL can perform
          tests of the New Functionality to confirm its compatibility with the
          AOL Service client software.  Should any new material, new
          functionality or features through the ICP Internet Site be released
          without notification to AOL, AOL will not be responsible for any
          adverse member experience until such time that compatibility tests can
          be performed and the new material, functionality or features qualified
          for the AOL Service.

                                      -41-

7.   AOL Internet Services Partner Support.  AOL will provide ICP with access
     -------------------------------------
     to the standard online resources, standards and guidelines documentation,
     technical phone support, monitoring and after-hours assistance that AOL
     makes generally available to similarly situated web-based partners.  AOL
     support will not, in any case, be involved with content creation on behalf
     of ICP or support for any technologies, databases, software or other
     applications which are not supported by AOL or are related to any ICP area
     other than the ICP Internet Site.  Support to be provided by AOL is
     contingent on ICP providing to AOL demo account information (where
     applicable), a detailed description of the ICP Internet Site's software,
     hardware and network architecture and access to the ICP Internet Site for
     purposes of such performance and the coordination load testing as AOL
     elects to conduct.

8.   ICP Programming - The terms and conditions of this Exhibit applicable to
     ---------------
     the ICP Internet Site shall apply equally to any ICP Programming that is
     (a) programmed in HTML or (b) web-based.

     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.

                  ------------------------
Company (which term, as used in this Section 2.04, excludes the Company's

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
permit, license or other authorization or such non-compliance could not
reasonably be expected to have a material adverse effect on the Company or its
business. There is no existing United States law, rule, regulation or order,
whether Federal, state, county or local, which would prohibit or restrict the
Company from, or otherwise materially adversely affect the Company in conducting
its business in any jurisdiction in which it is now conducting business.

     Section 2.08   Proprietary Information of Third Parties. To the Company's
                    ----------------------------------------
knowledge, no third party has claimed that any person employed by or affiliated
with the Company has (a) violated or may be violating any of the terms or
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.

     Section 2.09   Patents; Trademarks; Etc. Set forth in Schedule II is a list
                    ------------------------
and brief description of all domestic and foreign patents, patent rights, patent
applications, trademarks, trademark applications, service marks, service mark
applications, trade names and copyrights, and all applications for such which
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

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

non-performance), have received no notice of default and are not in default
(with due notice or lapse of time or both) under any agreement instrument,
commitment, plan or arrangement to which the Company is a party or by which it

Company has no present expectation or intention of not fully performing all its
obligations under each such agreement instrument, commitment, plan or
arrangement, and the Company has no knowledge of any breach or anticipated
breach by the other party to any agreement, instrument, commitment, plan or

experience in the industry and on assumptions of fact and opinion as to future

validity or enforceability of the indemnification and contribution provisions of

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.

     Section 6.02 Right of Participation. The Company shall, prior to any
                  ----------------------
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

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.

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

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
                  ---------------------
full each director of the Company who is not an employee of the Company for all
of his reasonable out-of-pocket expenses incurred in attending each meeting of
the Board of Directors of the Company or any Committee thereof.

     Section 6.10 Use of Proceeds. The Company shall use the proceeds from the

jeopardize rights of the Company, such as the attorney client privilege. The
Company shall cause each of its subsidiaries to permit AOL, so long as AOL is
not represented on the Board of Directors of such subsidiary, to attend meetings
of the Board of Directors of such subsidiary, except where such attendance could
jeopardize rights of the Company, such as the attorney client privilege.

determination shall comply with the requirements of Treasury Regulation Section

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

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
<PAGE>

          (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

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.

<PAGE>

     3.   Notice of Proposed Transfer. Prior to any proposed transfer of any
          ---------------------------
Preferred Shares or Conversion Shares (other than under the circumstances
described in Sections 4, 5 or 6), the holder thereof shall give written notice
to the Company of its intention to effect such transfer. Each such notice shall

of counsel shall be required for a transfer to one or more partners of the

certificate for Preferred Shares or Conversion Shares transferred as above
provided shall bear the legend set forth in Section 2, except that such
certificate shall not bear such legend if (i) such transfer is in accordance
with the provisions of Rule 144 (or any other rule permitting public sale

referred to above is to the further effect that the transferee and any
subsequent transferee (other than an affiliate of the Company) would be entitled
to transfer such securities in a public sale without registration under the
Securities Act. The restrictions provided for in this Section 3 shall not apply
to securities which are not required to bear the legend prescribed by Section 2
in accordance with the provisions of that Section.

     4.   Required Registration.
          ---------------------

          (a)  At any time beginning January 1, 2003, the holders of Restricted
Stock constituting at least 50% of the total shares of Restricted Stock then
outstanding may request the Company to register under the Securities Act all or
any portion of the shares of Restricted Stock held by such requesting holder or
holders for sale in the manner specified in such notice, provided that the
shares of Restricted Stock for which registration has been requested shall
constitute at least 25% of the total shares of Restricted Stock originally
issued (or any lesser percentage if the anticipated aggregate offering price
would exceed $10,000,000). For purposes of this Section 4 and Sections 5, 6,
13(a) and 13(d), the term "Restricted Stock" shall be deemed to include the
number of shares of Restricted Stock which would be issuable to a holder of
Preferred Shares upon conversion of all Preferred Shares held by such holder at
such time, provided, however, that the only securities which the Company shall
           --------- -------
be required to register pursuant hereto shall be shares of Common Stock, and
provided, further, however, that, in any underwritten public offering
- ------------------ -------
contemplated by this Section 4 or Sections 5 and 6, the holders of Preferred
Shares shall be entitled to sell such Preferred Shares to the underwriters for
conversion and sale of the shares of Common Stock issued upon conversion
thereof. Notwithstanding anything to the contrary contained herein, no request
may be made under this Section 4(a) within 120 days after the effective date of
a registration statement filed by the Company covering a firm commitment
underwritten public offering in which the holders of Restricted Stock shall have
been entitled to join pursuant to Sections 5 or 6.

          (b)  At any time after the earlier of: (i) January 1, 2003 and (ii)
the date 180 days following the effective date of the first underwritten public
offering of the Company's securities, when AOL owns at least 5% of the
outstanding capital stock of the Company, on a fully diluted basis (counting all
convertible securities and rights to purchase securities as if fully

                                       3
<PAGE>

converted or exercised, except that, with respect to the Warrant, Warrant Shares
(as defined in the Warrant) shall be counted only to the extent vested), AOL may
request the Company to register under the Securities Act all or any portion of
the shares of Restricted Stock held by AOL for sale in the manner specified in
such notice, provided that the anticipated aggregate offering price of the
shares of Restricted Stock for which registration has been requested would
exceed $2,500,000, and provided further, that AOL may not make such a request on
more than two (2) occasions or on any occasion within nine (9) months of a
previous request.

          (c)  Following receipt of any notice under this Section 4, the Company
shall immediately notify all holders of Restricted Stock from whom notice has
not been received and shall use its best efforts to register under the
Securities Act, for public sale in accordance with the method of disposition
specified in such notice from requesting holders, the number of shares of
Restricted Stock specified in such notice (and in all notices received by the
Company from other holders within 30 days after the giving of such notice by the
Company). If such method of disposition shall be an underwritten public offering
the Company will designate the managing underwriter of such offering which
managing underwriter shall be reasonably acceptable to a majority of the holders
selling Restricted Stock in such offering. The Company shall be obligated to
register Restricted Stock pursuant to this Section 4 on one occasion only,
provided, however, that such obligation shall be deemed satisfied only when a
- -----------------
registration statement covering all shares of Restricted Stock specified in
notices received as aforesaid, for sale in accordance with the method of
disposition specified by the requesting holders, shall have become effective
and, if such method of disposition is a firm commitment underwritten public
offering, all such shares shall have been sold pursuant thereto.

          (d)  The Company shall be entitled to include in any registration
statement referred to in this Section 4, for sale in accordance with the method
of disposition specified by the requesting holders, shares of Common Stock to be
sold by the Company for its own account, except as and to the extent that, in
the opinion of the managing underwriter (if such method of disposition shall be
an underwritten public offering), such inclusion would adversely affect the
marketing of the Restricted Stock to be sold. Except for registration statements
on Form S-4, S-8 or any successor thereto, the Company will not file with the
Commission any other registration statement with respect to its Common Stock,
whether for its own account or that of other stockholders, from the date of
receipt of a notice from requesting holders pursuant to this Section 4 until the
completion of the period of distribution of the registration contemplated
thereby.

     5.   Incidental Registration. If the Company at any time (other than
          -----------------------
pursuant to Section 4 or Section 6) proposes to register any of its securities
under the Securities Act for sale to the public, whether for its own account or
for the account of other security holders or both (except with respect to
registration statements on Forms S-4, S-8 or another form not available for
registering the Restricted Stock for sale to the public), each such time it will
give written notice to all holders of outstanding Restricted Stock of its
intention so to do. Upon the written request of any such holder, received by the
Company within 30 days after the giving of any such notice by the Company, to
register any of its Restricted Stock, the Company will use its best efforts to
cause the Restricted Stock as to which registration shall have been so requested
to be included in the securities to be covered by the registration statement
proposed to be filed by the Company, all to the extent requisite to permit the
sale or other disposition by the holder of such

                                       4
<PAGE>

Restricted Stock so registered, and, if such registration is not an underwritten
public offering, all subject to the right of the Company to reduce (pro rata
among the requesting holders based upon the number of shares of Restricted Stock
owned by such holders) the number of shares of the Purchasers proposed to be
registered to not less than one-third of the total number of shares in the
offering, if and to the extent that the Company shall be of the opinion that
such inclusion would adversely affect the marketing of the securities to be
sold.

     In the event that any registration pursuant to this Section 5 shall be, in
whole or in part, an underwritten public offering of Common Stock, the number of
shares of Restricted Stock to be included in such an underwriting may be reduced
without limitation (pro rata among the requesting holders based upon the number
of shares of Restricted Stock owned by such holders) if and to the extent that
the managing underwriter shall be of the opinion that such inclusion would
adversely affect the marketing of the securities to be sold by the Company
therein, provided, however, that such number of shares of Restricted Stock shall
not be reduced if any shares are to be included in such underwriting for the
account of any person other than the Company or requesting holders of Restricted
Stock.

     Notwithstanding the foregoing provisions, the Company may withdraw any
registration statement referred to in this Section 5 without thereby incurring
any liability to the holders of Restricted Stock.

     6.   Registration on Form S-3. If at any time (i) a holder or holders of
          ------------------------
the Preferred Shares or Restricted Stock then outstanding request that the
Company file a registration statement on Form S-3 or any successor thereto for a
public offering of all or any portion of the shares of Restricted Stock held by
such requesting holder or holders, the reasonably anticipated aggregate price to
the public of which would exceed $1,000,000, and (ii) the Company is a
registrant entitled to use Form S-3 or any successor thereto to register such
shares, then the Company shall use its best efforts to register under the
Securities Act on Form S-3 or any successor thereto, for public sale in
accordance with the method of disposition specified in such notice, the number
of shares of Restricted Stock specified in such notice, provided, however, that
the Company shall not be required to effect a registration pursuant to this
Section 6 more than once in any 12-month period. Whenever the Company is
required by this Section 6 to use its best efforts to effect the registration of
Restricted Stock, each of the procedures and requirements of Section 4
(including but not limited to the requirement that the Company notify all
holders of Restricted Stock from whom notice has not been received and provide
them with the opportunity to participate in the offering) shall apply to such
registration, provided, however, that there shall be no limitation on the number
of registrations on Form S-3 which may be requested and obtained under this
Section 6, and provided, further, however, that the requirements contained in
the first sentence of Section 4(a) shall not apply to any registration on
Form S-3 which may be requested and obtained under this Section 6.

     7.   Registration Procedures. If and whenever the Company is required by
          -----------------------
the provisions of Sections 4, 5 or 6 to use its best efforts to effect the
registration of any shares of Restricted Stock under the Securities Act, the
Company will, as expeditiously as possible:

                                       5
<PAGE>

          (a)  prepare and file with the Commission a registration statement
(which, in the case of an underwritten public offering pursuant to Section 4,
shall be on Form S-l, or on Form S-3 if the Company is eligible to so file, or
on another form of general applicability satisfactory to the managing
underwriter selected as therein provided) with respect to such securities and
use its best efforts to cause such registration statement to become and remain
effective for the period of the distribution contemplated thereby (determined as
hereinafter provided);

          (b)  prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
the period specified in paragraph (a) above and comply with the provisions of
the Securities Act with respect to the disposition of all Restricted Stock
covered by such registration statement in accordance with the sellers' intended
method of disposition set forth in such registration statement for such period;

          (c)  furnish to each seller of Restricted Stock and to each
underwriter such number of copies of the registration statement and the
prospectus included therein (including each preliminary prospectus) as such
persons reasonably may request in order to facilitate the public sale or other
disposition of the Restricted Stock covered by such registration statement;

          (d)  use its best efforts to register or qualify the Restricted Stock
covered by such registration statement under the securities or "blue sky" laws
of such jurisdictions as the sellers of Restricted Stock or, in the case of an
underwritten public offering, the managing underwriter reasonably shall request,
provided, however, that the Company shall not for any such purpose be required
to qualify generally to transact business as a foreign corporation in any
jurisdiction where it is not so qualified or to consent to general service of
process in any such jurisdiction;

          (e)  use its best efforts to list the Restricted Stock covered by such
registration statement with any securities exchange on which the Common Stock of
the Company is then listed;

          (f)  immediately notify each seller of Restricted Stock and each
underwriter under such registration statement, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any event of which the Company has knowledge as a result of which
the prospectus contained in such registration statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing;

          (g)  if the offering is underwritten and at the request of any seller
of Restricted Stock, use its best efforts to furnish on the date that Restricted
Stock is delivered to the under writers for sale pursuant to such registration:
(i) an opinion dated such date of counsel representing the Company for the
purposes of such registration, addressed to the underwriters and to such seller,
stating that such registration statement has become effective under the
Securities Act and that (A) to the best knowledge of such counsel, no stop order
suspending the

                                       6
<PAGE>

effectiveness thereof has been issued and no proceedings for that purpose have
been instituted or are pending or contemplated under the Securities Act, (B) the
registration statement, the related prospectus and each amendment or supplement
thereof comply as to form in all material respects with the requirements of the
Securities Act (except that such counsel need not express any opinion as to
financial statements contained therein) and (C) to such other effects as
reasonably may be requested by counsel for the underwriters or by such seller or
its counsel and (ii) a letter dated such date from the independent public
accountants retained by the Company, addressed to the underwriters and to such
seller, stating that they are independent public accountants within the meaning
of the Securities Act and that, in the opinion of such accountants, the
financial statements of the Company included in the registration statement or
the prospectus, or any amendment or supplement thereof, comply as to form in all
material respects with the applicable accounting requirements of the Securities
Act, and such letter shall additionally cover such other financial matters
(including information as to the period ending no more than five business days
prior to the date of such letter) with respect to such registration as such
underwriters reasonably may request; and

          (h)  make available for inspection by each seller of Restricted Stock,
any underwriter participating in any distribution pursuant to such registration
statement, and any attorney, accountant or other agent retained by such seller
or underwriter, all financial and other records, pertinent corporate documents
and properties of the Company, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any such seller,
underwriter, attorney, accountant or agent in connection with such registration
statement.

     For purposes of Section 7(a) and 7(b) and of Section 4(c), the period of
distribution of Restricted Stock in a firm commitment underwritten public
offering shall be deemed to extend until each underwriter has completed the
distribution of all securities purchased by it, and the period of distribution
of Restricted Stock in any other registration shall be deemed to extend until
the earlier of the sale of all Restricted Stock covered thereby and 120 days
after the effective date thereof.

     In connection with each registration hereunder, the sellers of Restricted
Stock will furnish to the Company in writing such information with respect to
themselves and the proposed distribution by them as reasonably shall be
necessary in order to assure compliance with federal and applicable state
securities laws.

     In connection with each registration pursuant to Sections 4, 5 or 6
covering an underwritten public offering, the Company and each seller agrees to
enter into a written agreement with the managing underwriter selected in the
manner herein provided in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
underwriter and companies of the Company's size and investment stature.

     8.   Expenses. All expenses incurred by the Company in complying with
          --------
Sections 4, 5 and 6, including, without limitation, all registration and filing
fees, printing expenses, fees and disbursements of counsel and independent
public accountants for the Company, fees and expenses (including counsel fees)
incurred in connection with complying with state securities or

                                       7
<PAGE>

"blue sky" laws, fees of the National Association of Securities Dealers, Inc.,
transfer taxes, fees of transfer agents and registrars, costs of insurance and
fees and disbursements of one counsel for the sellers of Restricted Stock
("Sellers' Counsel Expenses"), but excluding any Selling Expenses, are called
"Registration Expenses." All underwriting discounts and selling commissions
applicable to the sale of Restricted Stock are called "Selling Expenses."

     The Company will pay all Registration Expenses in connection with each
registration statement under Sections 4, 5 or 6. All Selling Expenses in
connection with each registration statement under Sections 4, 5 or 6 shall be
borne by the participating sellers in proportion to the number of shares sold by
each, or by such participating sellers other than the Company (except to the
extent the Company shall be a seller) as they may agree.

     9.   Indemnification and Contribution.
          --------------------------------

          (a)  In the event of a registration of any of the Restricted Stock
under the Securities Act pursuant to Sections 4, 5 or 6, the Company will
indemnify and hold harmless each seller of such Restricted Stock thereunder,
each underwriter of such Restricted Stock thereunder and each other person, if
any, who controls such seller or underwriter within the meaning of the
Securities Act, against any losses, claims, damages or liabilities, joint or
several, to which such seller, underwriter or controlling person may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which such Restricted Stock was
registered under the Securities Act pursuant to Sections 4, 5 or 6, any
preliminary prospectus or final prospectus contained therein, or any amendment
or supplement thereof, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse each
such seller, each such underwriter and each such controlling person for any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action,
provided, however, that the Company will not be liable in any such case if and
to the extent that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission so made in conformity with information furnished by any such
seller, any such underwriter or any such controlling person in writing
specifically for use in such registration statement or prospectus.

          (b)  In the event of a registration of any of the Restricted Stock
under the Securities Act pursuant to Sections 4, 5 or 6, each seller of such
Restricted Stock thereunder, severally and not jointly, will indemnify and hold
harmless the Company, each person, if any, who controls the Company within the
meaning of the Securities Act each officer of the Company who signs the
registration statement, each director of the Company, each underwriter and each
person who controls any underwriter within the meaning of the Securities Act,
against all losses, claims, damages or liabilities, joint or several, to which
the Company or such officer, director, underwriter or controlling person may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (`or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of any material
fact contained in

                                       8
<PAGE>

the registration statement under which such Restricted Stock was registered
under the Securities Act pursuant to Sections 4, 5 or 6, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereof, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will reimburse the Company and each
such officer, director, underwriter and controlling person for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action, provided, however,
that such seller will be liable hereunder in any such case if and only to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in reliance upon and in conformity with information pertaining to
such seller, as such, furnished in writing to the Company by such seller
specifically for use in such registration statement or prospectus, and provided,
further, however, that the liability of each seller hereunder shall be limited
to the proportion of any such loss, claim, damage, liability or expense which is
equal to the proportion that the public offering price of the shares sold by
such seller under such registration statement bears to the total public offering
price of all securities sold thereunder, but not in any event to exceed the net
proceeds received by such seller from the sale of Restricted Stock covered by
such registration statement.

          (c)  Promptly after receipt by an indemnified party hereunder of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to such indemnified party other than under this Section 9 and shall only relieve
it from any liability which it may have to such indemnified party under this
Section 9 if and to the extent the indemnifying party is prejudiced by such
omission. In case any such action shall be brought against any indemnified party
and it shall notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with counsel
satisfactory to such indemnified party, and, after notice from the indemnifying
party), to such indemnified party of its election so to assume and undertake the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under this Section 9 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation and of liaison with counsel so selected; provided,
however, that, if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be reasonable defenses available to it which are
different from or additional to those available to the indemnifying party or if
the interests of the indemnified party reasonably may be deemed to conflict with
the interests of the indemnifying party, the indemnified party shall have the
right to select a separate counsel and to assume such legal defenses and
otherwise to participate in the defense of such action, with the expenses and
fees of such separate counsel and other expenses related to such participation
to be reimbursed by the indemnifying party as incurred.

          (d)  In order to provide for just and equitable contribution to joint
liability under the Securities Act in any case in which either (i) any holder of
Restricted Stock exercising rights under this Agreement, or any controlling
person of any such holder, makes a claim for

                                       9

<PAGE>

indemnification pursuant to this Section 9 but it is judicially determined (by
the entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 9 provides for indemnification in such case, or (ii)
contribution under the Securities Act may be required on the part of any such
selling holder or any such controlling person in circumstances for which
indemnification is provided under this Section 9; then, and in each such case,
the Company and such holder will contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (after contribution from
others) in such proportion so that such holder is responsible for the portion
represented by the percentage that the public offering price of its Restricted
Stock offered by the registration statement bears to the public offering price
of all securities offered by such registration statement, and the Company is
responsible for the remaining portion; provided, however, that, in any such
case, (A) no such holder will be required to contribute my amount in excess of
the public offering price of all such Restricted Stock offered by it pursuant to
such registration statement; and (B) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
will be entitled to contribution from any person or entity who was not guilty of
such fraudulent misrepresentation.

     10.  Changes in Common Stock or Preferred Stock. If, and as often as, there
          ------------------------------------------
is any change in the Common Stock or the Preferred Stock by way of a stock
split, stock dividend, combination or reclassification, or through a merger,
consolidation, reorganization or recapitalization, or by any other means,
appropriate adjustment shall be made in the provisions hereof so that the rights
and privileges granted hereby shall continue with respect to the Common Stock or
the Preferred Stock as so changed.

     11.  Rule 144 Reporting. With a view to making available the benefits of
          ------------------
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Stock to the public without registration, at all times
after 90 days after any registration statement covering a public offering of
securities of the Company under the Securities Act shall have become effective,
the Company agrees to:

          (a)  make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act;

          (b)  use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and

          (c)  furnish to each holder of Restricted Stock forthwith upon request
a written statement by the Company as to its compliance with the reporting
requirements of such Rule 144 and of the Securities Act and the Exchange Act, a
copy of the most recent annual or quarterly report of the Company, and such
other reports and documents so filed by the Company as such holder may
reasonably request in availing itself of any rule or regulation of the
Commission allowing such holder to sell any Restricted Stock without
registration.

     12.  Representations and Warranties of the Company. The Company represents
          ---------------------------------------------
and warrants to you as follows:

          (a)  The execution, delivery and performance of this Agreement by the
Company have been duly authorized by all requisite corporate action and will not
violate any order of any court or other agency of government, the Charter or By-
laws of the Company or any provision of any indenture, agreement or other
instrument to which it or any or its properties or assets is bound, 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 intent or result in
the creation or imposition of any lien, charge or encumbrance of any nature
whatsoever upon any of the properties or assets of the Company.

          (b)  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, 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.

     13.  Miscellaneous.
          -------------

          (a)  All covenants and agreements contained in this Agreement by or on
behalf of any of the parties hereto shall bind and inure to the benefit of the
respective successors and assigns of the parties hereto (including without
limitation transferees of any Preferred Shares or Restricted Stock), whether so
expressed or not, provided, however, that registration rights conferred herein
on the holders of Preferred Shares or Restricted Stock shall only inure to the
benefit of a transferee of Preferred Shares or Restricted Stock if (i) there is
transferred to such transferee at least 50% of the total shares of Restricted
Stock originally issued pursuant to the Purchase Agreement to the direct or
indirect transferor of such transferee or (ii) such transferee is a partner,
shareholder or affiliate of a party hereto.

          (b)  All notices, requests, consents and other communications
hereunder shall be in writing and shall be delivered in person, mailed by
certified or registered mail, return receipt requested, or sent by telecopier or
telex, addressed as follows:

     if to the Company or any other party hereto, at the address of such party
set forth in the Purchase Agreement;

     if to any subsequent holder of Preferred Shares or Restricted Stock, to it
at such address as may have been furnished to the Company in writing by such
holder;

or, in any case, at such other address or addresses as shall have been furnished
in writing to the Company (in the case of a holder of Preferred Shares or
Restricted Stock) or to the holders of Preferred Shares or Restricted Stock (in
the case of the Company) in accordance with the provisions of this paragraph.

                                      11

<PAGE>

          (c)  This Agreement shall be governed by and construed in accordance
with the laws of Delaware.

          (d)  This Agreement may not be amended or modified, and no provision
hereof may be waived, without the written consent of the Company and the holders
of at least two-thirds of the outstanding shares of Restricted Stock; provided
that AOL's rights and obligations hereunder may not be amended or modified
without the written consent of AOL and Thomson's rights and obligations
hereunder may not be amended or modified without the written consent of Thomson.

          (e)  This Agreement may be executed in two or more counterparts, each
of which shall be deemed an original, but all of which together shall constitute
one and the same intent.

          (f)  The obligations of the Company to register shares of Restricted
Stock under Sections 4, 5 or 6 shall terminate on the tenth anniversary of the
date of this Agreement.

          (g)  If requested in writing by the underwriters for an underwritten
public offering of securities of the Company, each holder of Restricted Stock
who is a party to this Agreement (if still a holder of Restricted Stock at the
time) shall agree not to sell publicly any shares of Restricted Stock or any
other shares of Common Stock (other than shares of Restricted Stock or other
shares of Common Stock being registered in such offering), without the consent
of such underwriters (the "Lock-Up Obligation"), for a period of not more than
180 days in the case of an initial public offering or 90 days in the case of all
other public offerings following the effective date of the registration
statement relating to such offering; provided, however, that all persons
entitled to registration rights with respect to shares of Common Stock who are
not parties to this Agreement, all other persons selling shares of Common Stock
in such offering, and all executive officers and directors of the Company shall
also have agreed not to sell publicly their Common Stock under the circumstances
and pursuant to the terms set forth in this Section 13(g). Notwithstanding the
foregoing, the Lock-Up Obligation shall not apply to AOL, with respect to the
Shares purchased by AOL pursuant to the Warrant only, for any offering other
than the Company's initial public offering.

          (h)  Notwithstanding the provisions of Section 7(a), the Company's
obligation to file a registration statement, or cause such registration
statement to become and remain effective, shall be suspended for a period not to
exceed 90 days in any 12-month period (i) if there exists at the time material
non-public information relating to the Company which, in the reasonable opinion
of the Company, should not be disclosed or (ii) if such filing would materially
and adversely affect a pending or scheduled public offering of the Company's
securities.

          (i)  The Company shall not grant to any third party any registration
rights more favorable than or inconsistent with any of those contained herein,
so long as any of the registration rights under this Agreement remains in
effect.

                                      12

<PAGE>

          (j)  If any provision of this Agreement shall be held to be illegal,
invalid or unenforceable, such illegality, invalidity or unenforceability shall
attach only to such provision and shall not in any manner affect or render
illegal, invalid or unenforceable any other provision of this Agreement, and
this Agreement shall be carried out as if any such illegal, invalid or
unenforceable provision were not contained herein.

          (k)  Thomson and the Company agree that the provisions of Sections
2.01 of the Amended and Restated Agreement Among Thomson and Founders, dated as
of March 31, 1999, are hereby deleted from that agreement and shall be of no
further force or effect.

                                                December 23, 1999


1.   General.
     -------

          (a) THIS CERTIFIES that, for value received, AMERICA ONLINE, INC.
("AOL"), or assigns, is entitled to subscribe for and purchase from CCBN.COM,
INC., a Delaware corporation (the "Corporation"), at any time or from time to
time during the period (the "Exercise Period") commencing with the date hereof
and ending on the sixth anniversary of the date hereof (subject to being
extended as set forth in Sections 9(d) hereof), on the terms and subject to the
provisions hereinafter set forth, up to 1,596,650 shares (subject to adjustment
as provided herein) of fully paid and non-assessable (i) shares of the series of
preferred stock determined in accordance with Exhibit C hereto, in each case
                                              ---------
with the same rights, preferences and privileges, other than the original
issuance price and liquidation preference (which, in each case, shall be equal
to the initial Warrant Price (as defined below)), as the Series E-l Preferred
Stock (the "Preferred Stock"), or (ii) in the event the Preferred Stock shall
prior to exercise or exchange of this Warrant have been converted into Common
Stock, $.00l par value (the "Common Stock") of the Corporation as a result of
the automatic conversion of Preferred Stock pursuant to Article FOURTH, Section
2(b)(i) of the Amended and Restated Certificate of Incorporation of the
Corporation (the "Certificate of Incorporation"), that number of shares of
Common Stock into which such number of shares of Preferred Stock is converted
("Mandatory Conversion Event"), at any time or from time to time during the
Exercise Period, in each case, at a price per share (the "Warrant Price") as set
forth on Exhibit A hereto and at such times as shall be determined in accordance
         ---------
with Section 1(b) hereof.

This Warrant is being issued pursuant to an Interactive Services Agreement dated
as of the date hereof (the "Agreement"), between the Corporation and AOL as
partial consideration for the services to be provided by AOL to the Corporation
pursuant to that agreement, and the warrants will be treated accordingly under
Section 83 of the Internal Revenue Code for federal income tax purposes. All
terms used but not defined herein shall have the meanings set forth in the
Agreement. The shares of capital stock of the Corporation issuable upon exercise
or exchange of this Warrant are sometimes hereinafter referred to as the
"Warrant Shares," and, in connection therewith, all references herein to Warrant
Shares shall mean Preferred Stock until the

                                       1
<PAGE>

occurrence of a Mandatory Conversion Event, and upon and at all times after, the
occurrence of a Mandatory Conversion Event, shall mean Common Stock.

          (b)  This Warrant shall become exercisable as to that number of
Warrant Shares, and at such times, as are determined in accordance with Exhibit
                                                                        -------
A attached hereto; provided, however, that this Warrant shall become
- -                  -----------------
automatically exercisable as to all of the Warrant Shares immediately upon the
occurrence of a Stipulated Event with a Warrant Price for such accelerated
Warrant shares equal to ninety percent (90%) of the Acceleration Fair Market
Value (as defined below). The Corporation shall give AOL written notice of such
Stipulated Event at least five (5) business days prior to the consummation of
the Stipulated Event. As used herein, the term "Stipulated Event" shall mean (a)
a Corporate Transaction (as hereinafter defined) involving a competitor of AOL
listed on Exhibit D hereto (an "AOL Competitor") or (b) a termination of the
          ---------
Agreement that results from a material breach by the Corporation of the
Agreement. "Corporate Transaction" means (A) any consolidation or merger of the
Corporation with or into any other corporation or other entity, other than any
merger or consolidation resulting in the holders of the capital stock of the
Corporation entitled to vote for the election of directors holding a majority of
the capital stock of the surviving or resulting corporation or other entity
entitled to vote for the election of directors, (B) any person or entity
(including any affiliates thereof) other than Jeffrey P. Parker (or his
affiliate(s)) becoming the holder of a majority of the capital stock of the
Corporation entitled to vote for the election of directors, (C) Jeffrey P.
Parker (or his affiliates(s)) becoming the holder of more than 60% of the
capital stock of the Corporation entitled to vote for the election of directors,
or (D) any sale or other disposition by the Corporation of all or substantially
all of its assets or capital stock.

          (c)  In the event of a proposed Corporate Transaction involving an
entity other than an AOL Competitor, the Corporation shall deliver a written
notice of such Corporate Transaction to AOL at least twenty (20) business days
prior to the consummation of the Corporate Transaction (the "Corporate
Transaction Notice") and AOL shall, upon delivery of the Corporate Transaction
Notice, have the right and option to elect, by delivering written notice to the
Corporation (the "Acceleration Notice") up to five (5) business days prior to
the consummation of such Corporate Transaction, to have the Warrant become
exercisable as provided in Sections 1(d) through (g) below; provided, however,
                                                            --------- -------
that if the Corporation fails to deliver the Corporate Transaction Notice in a
timely manner, then AOL shall have the right and option to elect, by delivering
an Acceleration Notice to the Corporation, regardless of whether the Corporation
delivers the Corporate Transaction Notice, at any time prior to the later of (A)
ten (10) business days after receipt of the Corporate Transaction Notice or (B)
ten (10) business days after the consummation of such Corporate Transaction, to
have the Warrant become exercisable as provided in Sections 1(d) through (g)
below. If the proposed Corporate Transaction referenced in any Corporate
Transaction Notice is not consummated, then the Warrant shall continue to vest
pursuant to the terms hereof, notwithstanding the delivery of any Acceleration
Notice, and Sections 1(b) through (g) hereof shall continue to apply and shall
be in full force and effect.

          (d)  If a Corporate Transaction involves any person or entity other
than an AOL Competitor, then AOL shall have the right and option to elect, by
delivering the Acceleration Notice as provided in Section 1(c) hereof:

                                       2
<PAGE>

               (i) to have the Warrant become exercisable immediately as to one-
     half (1/2) of all then unvested Warrant Shares on the date of the
     consummation of such Corporate Transaction (such date the "Acceleration
     Date") with a Warrant Price for such accelerated Warrant Shares equal to
     ninety percent (90%) of the Acceleration Fair Market Value and the
     remaining unvested Warrant Shares shall continue to vest as provided in
     Exhibit A; or
     ---------

               (ii) to not have the Warrant accelerate as provided in Section
     l(d)(i) above, and the Warrant Shares shall continue to vest as provided in

     Exhibit A hereto; provided, however, that anything contained herein to the
     ---------         --------- -------
     contrary notwithstanding, the Warrant Price of Warrant Shares, as they
     vest, shall be the lesser of: (i) ninety percent (90%) of the Acceleration
     Fair Market Value and (ii) ninety percent (90%) of Fair Market Value (as
     defined in Exhibit A hereto).
                ---------

          (e) Anything contained herein to the contrary notwithstanding, if,
within six (6) months after the consummation of the Corporate Transaction, AOL
determines in its reasonable discretion that a Corporate Transaction inhibits,
impairs or otherwise adversely impacts AOL's ability or the Corporation's
ability to meet and/or perform its or their respective obligations pursuant to
the Agreement (as the same may be amended from time to time), then AOL shall
deliver a notice in writing to the Corporation and this Warrant shall become
immediately exercisable as to all of the Warrant Shares upon delivery of such
notice, with a Warrant Price for such accelerated Warrant shares equal to the
lesser of (A) ninety percent (90%) of the Acceleration Fair Market Value or (B)
90% of the Fair Market on the date of delivery of the Notice.

          (f) "Acceleration Fair Market Value" means the fair market value of
the consideration paid to the Corporation in the Corporate Transaction, divided
by the number of shares of Common Stock, and its equivalents (determined on a
fully diluted basis), transferred in such Corporate Transaction; provided, that
                                                                 --------
if the consideration paid to the Corporation in such Corporate Transaction is
other than cash, the value of such non-cash consideration shall be determined in
good faith by the Board of Directors of the Corporation and the holder of this
Warrant.

          (g) If the holder of this Warrant receives the Corporate Transaction
Notice and does not deliver the Acceleration Notice as provided in Section 1(c)
hereof, then the holder will be deemed to have elected to accelerate the Warrant
pursuant to Section l(d)(i) hereof.

2. Exercise of Warrant. The rights represented by this Warrant may be exercised
   ----------- -------
by the holder hereof, as to those Warrant Shares for which this Warrant is then
exercisable as determined in accordance with Section 1, in whole or in part, at
any time or from time to time during the Exercise Period, by the surrender of
this Warrant (properly endorsed) at the office of the Corporation at 200
Portland St., Boston, MA 02114, Attention: President, or at such other agency or
office of the Corporation in the United States of America as it may designate by
notice in writing to the holder hereof at the address of such holder appearing
on the books of the Corporation, and by payment (either in cash, by check, by
cancellation of indebtedness and/or in shares of capital stock of the
Corporation valued at Fair Market Value (as hereinafter defined) on

                                       3
<PAGE>

the date of such exercise) to the Corporation of the Warrant Price for each
Warrant Share being purchased. In the event of the exercise of the rights
represented by this Warrant, a certificate or certificates for the Warrant
Shares so purchased, registered in the name of the holder, and if this Warrant
shall not have been exercised for all of the Warrant Shares, a new Warrant,
registered in the name of the holder hereof, of like tenor to this Warrant,
shall be delivered to the holder hereof within a reasonable time, not exceeding
ten days, after the rights represented by this Warrant shall have been so
exercised. The person in whose name any certificate for Warrant Shares is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which the Warrant was
surrendered and payment of the Warrant Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Corporation are closed, such person shall be deemed to have become the
holder of such shares at the close of business on the next succeeding date on
which the stock transfer books are open.

3. Exchange of Warrant. In addition to, and independent of, the rights of the
   -------------------
holder of this Warrant set forth in Section 2 hereof, the holder hereof may at
any time or from time to time elect to receive, without the payment by the
holder of any additional consideration, that number of Warrant Shares determined
as hereinafter provided in this Section 3 by the surrender of this Warrant or
any portion hereof to the Corporation in respect to Warrant Shares then vested,
accompanied by an executed Notice of Exchange in substantially the form thereof
attached hereto (the "Net Issue Election"). Thereupon, the Corporation shall
issue to the holder hereof such number of fully paid and nonassessable Warrant
Shares as is computed using the following formula:

                                  X = Y (A-B)
                                      -------
                                         A

where X =  the number of Warrant Shares to be issued to the holder pursuant to
           this Section 3.

      Y =  the number of vested Warrant Shares covered by this Warrant in
           respect of which the Net Issue Election is made pursuant to this
           Section 3.

      A =  the Fair Market Value (as hereinafter defined) of one Warrant Share
           determined at the time the Net Issue Election is made pursuant to
           this Section 3 (the "Determination Date").

      B =  the Warrant Price in effect under this Warrant at the time the Net
           Issue Election is made pursuant to this Section 3.

For purposes of the above calculation, "Fair Market Value" of one Warrant Share
as of the Determination Date shall mean:

          (i) if as a result of a Mandatory Conversion Event the Warrant Shares
mean Common Stock as set forth in Section 1, then (A) if the Common Stock of the
Corporation is not then traded on a national securities exchange, the average of
the closing prices quoted on the National Association of Securities Dealers,
Inc. Automated Quotation National Market

                                       4
<PAGE>

System, if applicable, or the average of the last bid and asked prices of the
Common Stock quoted in the over-the-counter-market or (B) if the Common Stock is
then traded on a national securities exchange, the average of the high and low
prices of the Common Stock listed on the principal national securities exchange
on which the Common Stock is so traded, in each case for the Determination Date
and the nineteen (19) trading days immediately preceding the Determination Date
or, if such date is not a business day on which shares are traded, the next
immediately preceding trading day;

          (ii)  in the event of a Warrant Exchange in connection with a
Corporate Transaction, the value per share of Common Stock received or
receivable by each holder thereof (assuming, in the case of a sale of assets,
the Corporation is liquidated immediately following such sale and the
consideration paid to the Corporation is immediately distributed to its
stockholders); and

          (iii) in all other circumstances, the fair market value per share of
Common Stock shall be determined by mutual agreement between the Corporation and
the holder of this Warrant; provided, that if no such mutual agreement can be
                            --------
reached within five business days after delivery of the Notice of Exchange
referred to above, then the fair market value per share of Common Stock shall be
as determined by a nationally recognized independent investment banking firm,
jointly selected by the Corporation and the holder of this Warrant or, if such
selection cannot be made within five business days thereof, then by a nationally
recognized independent investment banking firm selected by the American
Arbitration Association then obtaining; provided, that the cost or expense of
                                        --------
any such investment banking firm shall be borne equally by the Corporation and
the holder of the Warrant.

The closing of any Warrant Exchange shall take place at the offices of the
Corporation on the date specified in the Notice of Exchange (the "Exchange
Date"), which shall be not less than five and not more than 30 days after the
delivery of such Notice. At such closing, the Corporation shall issue and
deliver to the holder or its designee a certificate or certificates for the
Warrant Shares to be issued upon such Warrant Exchange, registered in the name
of the holder or such designee, and if such Warrant Exchange shall not have been
for all Warrant Shares, a new Warrant, registered in the name of the holder, of
like tenor to this Warrant for the number of shares still subject to this
Warrant following such Warrant Exchange.

4.  Adjustment of Warrant Price; Adjustment of Warrant Shares. If, at any time
    ---------------------------------------------------------
during the Exercise Period, the number of outstanding shares of any series of
preferred stock of the Corporation or Common Stock is (i) increased by a stock
dividend payable in shares of capital stock or by a subdivision or split-up of
shares of such capital stock, or (ii) decreased by a combination of shares of
capital stock, then, following the record date fixed for the determination of
holders of capital stock entitled to receive the benefits of such stock
dividend, subdivision, split-up, or combination, the (1) Warrant Price shall be
adjusted on the effective date of such stock dividend, subdivision, split-up or
combination to a new amount equal to the product of (A) the Warrant Price in
effect on such record date and (B) the quotient obtained by dividing (x) the
number of shares of Common Stock outstanding on such record date (without giving
effect to the event referred to in the foregoing clause (i) or (ii)), by (y) the
number of shares of Common Stock which would be outstanding immediately after
the event referred to in the foregoing clause

                                       5
<PAGE>

(i) or (ii), if such event had occurred immediately following such record date
and (2) the number of Warrant Shares shall be proportionately increased (in the
case of a subdivision, split-up or stock dividend) or proportionately decreased
(in the case of a combination).

5.  Representations and Warranties; Covenants as to Preferred Stock.
    ---------------------------------------------------------------

          (a) In connection with the exercise of the Warrant, the Corporation
shall make representations and warranties as to organization, authority,
capitalization, litigation.

          (b) Prior to or concurrent with the Warrant Shares becoming vested and
exercisable, the Corporation shall designate and authorize each series of
Preferred Stock listed on Exhibit C hereto and shall fix the original issuance
                          ---------
price of each such series in accordance with the definition of "Fair Market
Value" set forth in Exhibit A, or the provisions of Sections 1(b) through (g)
                    ---------
hereof, as applicable.

          (c) The Corporation covenants and agrees that all shares of Preferred
Stock which may be issued upon the exercise of the rights represented by this
Warrant, and all shares of Common Stock which may be issued upon the conversion
of the Preferred Stock will, upon issuance, be validly issued, fully paid and
non-assessable and free from all taxes, liens and charges with respect to the
issuance thereof. The Corporation further covenants and agrees that the
Corporation will from time to time take all such action as may be requisite to
assure that the stated or par value per share of the Preferred Stock and the
Common Stock is at all times equal to or less than the then effective Warrant
Price per share of Preferred Stock issuable upon exercise of this Warrant. The
Corporation further covenants and agrees that the Corporation will at all times
have authorized and reserved or shall authorize and reserve, free from
preemptive rights, a sufficient number of (a) shares of its Preferred Stock to
provide for the exercise of the rights represented by this Warrant and (b)
shares of Common Stock to provide for the conversion of the Preferred Stock
issuable upon exercise of this Warrant; provided, that AOL acknowledges that
                                        --------
Thomson Information Services, Inc. ("Thomson") may exercise its existing
preemptive rights in connection with the exercise of this Warrant, which
exercise by Thomson shall not reduce or affect the number of shares issued or
issuable to AOL pursuant to this Warrant. The Corporation further covenants and
agrees that if any shares of capital stock to be reserved for the purpose of the
issuance of shares of Preferred Stock upon the exercise of this Warrant require
registration with or approval of any governmental authority under any Federal or
state law before such shares may be validly issued or delivered upon exercise,
then the Corporation will in good faith and expeditiously as possible endeavor
to secure such registration or approval, as the case may be. If and so long as
the Preferred Stock or Common Stock issuable upon the exercise of the rights
represented by this Warrant is listed on any national securities exchange, the
Corporation will, if permitted by the rules of such exchange, list and keep
listed on such exchange, upon official notice of issuance, all shares of such
capital stock.

          (d) Reference is made to the Series E Stock Purchase Agreement dated
as of the date hereof (the "Stock Purchase Agreement"), among AOL, the
Corporation and Thomson. The representations set forth in Sections 2.7 through
2.29 of the Stock Purchase Agreement are incorporated herein by reference.

                                       6
<PAGE>

          (e) The Corporation further covenants and agrees that the holder
hereof will be entitled to the benefits of any adjustment prior to the exercise
hereof pursuant to any anti-dilution protection and any notice of adjustment of
the conversion price provided to the holders of Preferred Stock in accordance
with the Certificate of Incorporation.

6. No Shareholder Rights. This Warrant shall not entitle the holder hereof to
   ---------------------
any voting rights or other rights as a shareholder of the Corporation.

7. Restrictions on Transfer. The holder of this Warrant acknowledges that
   ------------------------
neither this Warrant nor the Warrant Shares have been registered under the
Securities Act of 1933, as amended (the "Securities Act") and the holder of this
Warrant agrees that no sale, transfer, assignment, hypothecation or other
disposition of this Warrant or the Warrant Shares shall be made in the absence
of (a) current registration statement under the Securities Act as to this
Warrant or the Warrant Shares and the registration or qualification of this
Warrant or the Warrant Shares under any applicable state securities laws is then
in effect or (ii) an opinion of counsel reasonably satisfactory to the
Corporation to the effect that such registration or qualification is not
required. Each certificate or other instrument for Warrant Shares issued upon
exercise of this Warrant shall, if required under the Securities Act or the
rules promulgated thereunder, be imprinted with a legend substantially to the
foregoing effect.

8. Rights of the Holder: Investigation; Hart-Scott Rodino.
   ------------------------------------------------------

          (a) The Corporation hereby grants to the holder of this Warrant those
rights set forth on Exhibit B attached hereto, the provisions of which are
                    ---------
incorporated herein by reference and made a part hereof as if set forth herein
in their entirety.

          (b) Anything contained herein to the contrary notwithstanding, the
shares of Preferred Stock or Common Stock issuable upon exercise of this Warrant
and the Common Stock issuable upon conversion of such shares of Preferred Stock
shall be entitled to all rights and benefits accorded thereto in any investor
rights or shareholders or similar agreement between and/or among the Corporation

9. Transfer of Warrant; Amendment. Subject to the restriction set forth in
   ------------------------------
Section 7, this Warrant, as to unvested Warrant Shares, and all rights hereunder
are transferable, in whole, or in part, only with the consent of the
Corporation; provided, however, that transfers of this Warrant (i) in whole or
             --------- -------
in part, to subsidiaries or affiliates of the holder hereof, and (ii) with
respect to vested Warrant Shares, in each case, shall not require such consent.
Transfers shall be made at the agency or office of the Corporation referred to
in Section 2, by the holder hereof in person or by duly authorized attorney,
upon surrender of this Warrant properly endorsed. Each taker and holder of this
Warrant, by taking or holding the same, consents and agrees that this Warrant,
when endorsed, in blank, shall be deemed negotiable, and, when so endorsed the
holder hereof may be treated by the Corporation and all other persons dealing
with this Warrant as the absolute owner hereof for any purposes and as the
person entitled to exercise the rights represented by this Warrant, or to the
transfer hereof on the books of the Corporation, any notice to the contrary
notwithstanding; but until each transfer on such books, the Corporation may
treat the registered holder hereof as the owner hereof for all purposes.

10. Reorganizations. Etc. In case, at any time during the Exercise Period, of
    --------------------
any capital reorganization, of any reclassification of the stock of the
Corporation (other than a change in par value or from par value to no par value
or from no par value to par value or as a result of a stock dividend or
subdivision, split-up or combination of shares), or the consolidation or merger
of the Corporation with or into another corporation (other than a consolidation
or merger in which the Corporation is the continuing operation and which does
not result in any change in the Common Stock) or of the sale of all or
substantially all the properties and assets of the Corporation as an entirety to
any other corporation, this Warrant shall, after such reorganization,
reclassification, consolidation, merger or sale, be exercisable for the kind and
number of shares of stock or other securities or property of the Corporation or
of the corporation resulting from such consolidation or surviving such merger or
to which such properties and assets shall have been sold to which such holder
would have been entitled if he had held the Preferred Stock issuable upon the
exercise of this Warrant or the Common Stock issuable upon conversion of the
Preferred Stock immediately prior to such reorganization, reclassification,
consolidation, merger or sale. In any such reorganization or other action or
transaction described above, appropriate provision shall be made with respect to
the rights and interests of the holder of this Warrant to the end that the
provisions hereof (including, without limitation, provisions for adjustment of
the Warrant Price and of the number of shares purchasable and receivable upon
the exercise of this Warrant) shall thereafter be applicable, as nearly as may
be, in relation to any shares of stock, securities or assets thereafter
deliverable upon the exercise hereof.

11. Lost Stolen, Mutilated or Destroyed Warrant. If this Warrant is lost,
    -------------------------------------------
stolen, mutilated or destroyed, the Corporation may, on such terms as to
indemnity or otherwise as it may in its discretion impose (which shall, in the
case of a mutilated Warrant, include the surrender thereof), issue a new Warrant
of like denomination and tenor as the Warrant so lost, stolen, mutilated or

                                       8

destroyed. Any such new Warrant shall constitute an original contractual
obligation of the Corporation, whether or not the allegedly lost, stolen,
mutilated or destroyed Warrant shall be at any time enforceable by anyone.

    -----------------------
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.
