                        COMMON STOCK PURCHASE AGREEMENT
                        -------------------------------

     This Common Stock Purchase Agreement ("Agreement") is entered into as of
                                            ---------
December 9, 1997 between Moai Technologies, Inc., a California corporation (the
"Company"), and Anne Perlman ("Purchaser").
 -------                       ---------

     1.  Sale of Stock.  On the Purchase Date (as defined below) the Company
         -------------
will issue and sell to Purchaser, and Purchaser will purchase from the Company,
738,750 shares of the Company's Common Stock (the "Shares") at a purchase price
                                                   ------
of $0.06 per Share for a total purchase price of $44,325.00.  The term "Shares"
refers to the purchased shares of Common Stock and all securities received in
replacement of or in connection with such shares pursuant to stock dividends or
splits, all securities received in replacement of such shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of such shares.

     2.  Purchase.  The purchase and sale of the Shares under this Agreement
         --------
shall occur at the principal office of the Company simultaneously with the
execution of this Agreement by the parties, or at such other time and place as
the Company and Purchaser shall agree (the "Purchase Date").  On the Purchase
                                            -------------
Date, the Company will deliver to Purchaser a certificate representing the
Shares to be purchased by Purchaser (which shall be issued in Purchaser's name)
against payment of the purchase price therefor by Purchaser by delivery of a
promissory note in the form attached as Exhibit A to this Agreement and a Pledge
                                        ---------
and Security Agreement in the form attached as Exhibit B to this Agreement.
                                               ---------

     3.  Limitations on Transfer.  In addition to any other limitation on
         -----------------------
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares while the Shares are subject
to the Company's Repurchase Option (as defined below).  After any Shares have
been released from the Repurchase Option, Purchaser shall not assign, encumber
or dispose of any interest in such Shares except in compliance with the
provisions below and applicable securities laws.

         (a)  Repurchase Option.
              -----------------

              (i) In the event of the voluntary or involuntary termination of
Purchaser's employment or consulting relationship with the Company for any
reason (including death or disability), with or without cause, the Company shall
upon the date of such termination (the "Termination Date") have an irrevocable,
                                        ----------------
exclusive option (the "Repurchase Option") for a period of 60 days from such
                       -----------------
date to repurchase all or any portion of the Shares held by Purchaser as of the
Termination Date which have not yet been released from the Company's Repurchase
Option at the original purchase price per Share specified in Section 1 (adjusted
for any stock splits, stock dividends and the like); provided, however, that the
                                                     --------  -------
Repurchase Option shall continue for a period of up to one year from the
Termination Date to the extent that the Company reasonably determines that such
an extension of time is necessary to prevent the repurchase of
<PAGE>

the Shares from causing other capital stock of the Company to lose its status as
"qualified small business stock" under Section 1202 of the Internal Revenue Code
of 1986, as amended.

               (ii)  The Repurchase Option shall be exercised by the Company by
written notice to Purchaser or Purchaser's executor and, at the Company's
option, (A) by delivery to Purchaser or Purchaser's executor with such notice of
a check in the amount of the purchase price for the Shares being purchased, or
(B) in the event Purchaser is indebted to the Company, by cancellation by the
Company of an amount of such indebtedness equal to the purchase price for the
Shares being repurchased, or (C) by a combination of (A) and (B) so that the
combined payment and cancellation of indebtedness equals such purchase price.
Upon delivery of such notice and payment of the purchase price in any of the
ways described above, the Company shall become the legal and beneficial owner of
the Shares being repurchased and all rights and interest therein or related
thereto, and the Company shall have the right to transfer to its own name the
number of Shares being repurchased by the Company, without further action by
Purchaser.

               (iii) One hundred percent (100%) of the Shares shall initially be
subject to the Repurchase Option.  1/8th of the Shares shall be released from
the Repurchase Option on the date that is six months after the Vesting
Commencement Date (as set forth on the signature page of this Agreement), and
1/48th of the total number of Shares shall be released from the Repurchase
Option at the end of each month thereafter, until all Shares are released from
the Repurchase Option (provided in each case that Purchaser's employment or
consulting relationship with the Company has not been terminated prior to the
date of such release).  Fractional shares shall be rounded to the nearest whole
share.

               (iv)  Notwithstanding Section 3(a)(iii), the Repurchase Option
shall lapse in accordance with paragraph 6 of Purchaser's employment letter with
the Company dated December 9, 1997 (the "Employment Letter").
                                         -----------------

          (b)  Right of First Refusal.  Before any Shares held by Purchaser or
               ----------------------
any transferee of Purchaser (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
 ------
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section 3(b) (the "Right of First Refusal").
                   ----------------------

               (i)   Notice of Proposed Transfer.  The Holder of the Shares
                     ---------------------------
shall deliver to the Company a written notice (the "Notice") stating: (A) the
                                                    ------
Holder's bona fide intention to sell or otherwise transfer such Shares; (B) the
name of each proposed purchaser or other transferee ("Proposed Transferee"); (C)
                                                      -------------------
the number of Shares to be transferred to each Proposed Transferee; and (D) the
terms and conditions of each proposed sale or transfer. The Holder shall offer
the Shares at the same price (the "Offered Price") and upon the same terms (or
                                   -------------
terms as similar as reasonably possible) to the Company or its assignee(s).

               (ii)  Exercise of Right of First Refusal.  At any time within
                     ----------------------------------
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Shares proposed to be transferred

                                      -2-
<PAGE>

to any one or more of the Proposed Transferees, at the purchase price determined
in accordance with subsection (iii) below.

               (iii)  Purchase Price. The purchase price ("Purchase Price") for
                      --------------                       --------------
the Shares purchased by the Company or its assignee(s) under this Section 3(b)
shall be the Offered Price. If the Offered Price includes consideration other
than cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

               (iv)   Payment.  Payment of the Purchase Price shall be made, at
                      -------
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

               (v)    Holder's Right to Transfer.  If all of the Shares proposed
                      --------------------------
in the Notice to be transferred to a given Proposed Transferee are not purchased
by the Company and/or its assignee(s) as provided in this Section 3(b), then the
Holder may sell or otherwise transfer such Shares to that Proposed Transferee at
the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within sixty (60) days after the date of the Notice and
provided further that any such sale or other transfer is effected in accordance
with any applicable securities laws and the Proposed Transferee agrees in
writing that the provisions of this Section 3 shall continue to apply to the
Shares in the hands of such Proposed Transferee. If the Shares described in the
Notice are not transferred to the Proposed Transferee within such period, or if
the Holder proposes to change the price or other terms to make them more
favorable to the Proposed Transferee, a new Notice shall be given to the
Company, and the Company and/or its assignees shall again be offered the Right
of First Refusal before any Shares held by the Holder may be sold or otherwise
transferred.

               (vi)   Exception for Certain Transfers.  Anything to the contrary
                      -------------------------------
contained in this Section 3(b) notwithstanding, the donative transfer of any or
all of the Shares during Purchaser's lifetime or on Purchaser's death by will or
intestacy to the San Jose Children's Discovery Museum or to Purchaser's
Immediate Family or a trust for the benefit of Purchaser's Immediate Family
shall be exempt from the provisions of this Section 3(b).  "Immediate Family" as
                                                            ----------------
used herein shall mean spouse, lineal descendant or antecedent, father, mother,
brother or sister.  In such case, the transferee or other recipient shall
receive and hold the Shares so transferred subject to the provisions of this
Agreement, and there shall be no further transfer of such Shares except in
accordance with the terms of this Agreement.

          (c)  Involuntary Transfer.
               --------------------

               (i)    Company's Right to Purchase upon Involuntary Transfer.  In
                      -----------------------------------------------------
the event, at any time after the date of this Agreement, of any transfer by
operation of law or other involuntary transfer (including death or divorce, but
excluding a transfer to Immediate Family as set forth in Section 3(b)(vi)) of
all or a portion of the Shares by the record holder thereof, the Company shall
have an option to purchase all of the Shares transferred. The

                                      -3-
<PAGE>

purchase price for Shares which have not been released from the Repurchase
Option shall be the original purchase price per share specified in Section 1
(adjusted for any stock splits, stock dividends and the like); the purchase
price for Shares which have been released from the Repurchase Option shall be
the greater of the purchase price specified in Section 1 (adjusted for any stock
splits, stock dividends and the like) and the fair market value of the Shares on
the date of transfer. Upon such a transfer, the person acquiring the Shares
shall promptly notify the Secretary of the Company of such transfer. The right
to purchase such Shares shall be provided to the Company for a period of thirty
(30) days following receipt by the Company of written notice by the person
acquiring the Shares.

               (ii) Price for Involuntary Transfer.  With respect to any shares
                    ------------------------------
which have not been released from the Repurchase Option to be transferred
pursuant to Section 3(c)(i), the price per Share shall be a price set by the
Board of Directors of the Company that will reflect the current value of the
stock in terms of present earnings and future prospects of the Company. The
Company shall notify Purchaser or his or her executor of the price so determined
within thirty (30) days after receipt by it of written notice of the transfer or
proposed transfer of Shares. However, if the Purchaser does not agree with the
valuation as determined by the Board of Directors of the Company, the Purchaser
shall be entitled to have the valuation determined by an independent appraiser
to be mutually agreed upon by the Company and the Purchaser and whose fees shall
be borne equally by the Company and the Purchaser.

          (d)  Assignment.  The right of the Company to purchase any part of the
               ----------
Shares may be assigned in whole or in part to any shareholder or shareholders of
the Company or other persons or organizations.

          (e)  Restrictions Binding on Transferees.  All transferees of Shares
               -----------------------------------
or any interest therein will receive and hold such Shares or interest subject to
the provisions of this Agreement, including, insofar as applicable, the
Repurchase Option. Any sale or transfer of the Company's Shares shall be void
unless the provisions of this Agreement are met.

          (f)  Termination of Rights.  The Right of First Refusal and the option
               ---------------------
to repurchase the Shares in the event of an involuntary transfer granted the
Company by Section 3(c) shall terminate upon the first sale of Common Stock of
the Company to the general public pursuant to a registration statement filed
with and declared effective by the Securities and Exchange Commission under the
Securities Act of 1933, as amended (the "Securities Act") (the "IPO").  The
                                         --------------         ---
Repurchase Option shall not be affected by the IPO.

     4.   Escrow of Unvested Shares.  For purposes of facilitating the
          -------------------------
enforcement of the provisions of Section 3, Purchaser agrees, immediately upon
receipt of the certificate(s) for the Shares subject to the Repurchase Option,
to deliver such certificate(s), together with an Assignment Separate from
Certificate in the form attached to this Agreement as Exhibit C executed by
                                                      ---------
Purchaser and by Purchaser's spouse (if required for transfer), in blank, to the
Secretary of the Company, or the Secretary's designee, to hold such
certificate(s) and Assignment Separate from Certificate in escrow and to take
all such actions and to effectuate all such transfers and/or releases as are in
accordance with the terms of this Agreement.  Purchaser

                                      -4-
<PAGE>

hereby acknowledges that the Secretary of the Company, or the Secretary's
designee, is so appointed as the escrow holder with the foregoing authorities as
a material inducement to make this Agreement and that said appointment is
coupled with an interest and is accordingly irrevocable. Purchaser agrees that
said escrow holder shall not be liable to any party hereof (or to any other
party). The escrow holder may rely upon any letter, notice or other document
executed by any signature purported to be genuine and may resign at any time.
Purchaser agrees that if the Secretary of the Company, or the Secretary's
designee, resigns as escrow holder for any or no reason, the Board of Directors
of the Company shall have the power to appoint a successor to serve as escrow
holder pursuant to the terms of this Agreement.

     5.   Investment and Taxation Representations.  In connection with the
          ---------------------------------------
purchase of the Shares, Purchaser represents to the Company the following:

          (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Shares.  Purchaser is
purchasing the Shares for investment for his or her own account only and not
with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act.

          (b) Purchaser understands that the Shares have not been registered
under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.

          (c) Purchaser understands that the Shares are "restricted securities"
under applicable U.S. federal and state securities laws and that, pursuant to
these laws, Purchaser must hold the Shares indefinitely unless they are
registered with the Securities and Exchange Commission and qualified by state
authorities, or an exemption from such registration and qualification
requirements is available. Purchaser acknowledges that the Company has no
obligation to register or qualify the Shares for resale.  Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

          (d) Purchaser understands that Purchaser may suffer adverse tax
consequences as a result of Purchaser's purchase or disposition of the Shares.
Purchaser represents that Purchaser has consulted any tax consultants Purchaser
deems advisable in connection the purchase or disposition of the Shares and that
Purchaser is not relying on the Company for any tax advice.

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

          (a)  Legends.

               (i)  The certificate or certificates representing the Shares
shall bear the following legends (as well as any legends required by applicable
state and federal corporate and securities laws):

                    (A) THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                    REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN
                    ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN
                    CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF.  NO SUCH
                    SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN EFFECTIVE
                    REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF
                    COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH
                    REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF
                    1933.

                    (B) THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE
                    TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN
                    AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF
                    WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

                    (C) Any legend required to be placed thereon by the
                    California Commissioner of Corporations.

               (ii) Upon termination of the Right of First Refusal and the
expiration or exercise of the Repurchase Option, a new certificate or
certificates representing the Shares not repurchased shall be issued, on
request, without the legend referred to in Section 6(a)(i)(B) and delivered to
Purchaser.

          (b)  Stop-Transfer Notices.  Purchaser agrees that, in order to ensure
               ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (c)  Refusal to Transfer.  The Company shall not be required (i) to
               -------------------
transfer on its books any Shares that have been sold or otherwise transferred in

of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

                                      -6-
<PAGE>

     7.  No Employment Rights.  Nothing in this Agreement shall affect in any
         --------------------
manner whatsoever the right or power of the Company, or a parent or subsidiary
of the Company, to terminate Purchaser's employment, for any reason, with or
without cause.

     8.  Section 83(b) Election.  Purchaser understands that Section 83(a) of
         ----------------------
the Internal Revenue Code of 1986, as amended (the "Code"), taxes as ordinary
                                                    ----
income the difference between the amount paid for the Shares and the fair market
value of the Shares as of the date any restrictions on the Shares lapse.  In
this context, "restriction" means the right of the Company to buy back the
               -----------
Shares pursuant to the Repurchase Option set forth in Section 3(a) of this
Agreement.  Purchaser understands that Purchaser may elect to be taxed at the
time the Shares are purchased, rather than when and as the Repurchase Option
expires, by filing an election under Section 83(b) (an "83(b) Election") of the
                                                        --------------
Code with the Internal Revenue Service within 30 days from the date of purchase.
A blank 83(b) election is attached hereto as Exhibit D.  Even if the fair market
                                             ---------
value of the Shares at the time of the execution of this Agreement equals the
amount paid for the Shares, the election must be made to avoid income under
Section 83(a) in the future.  Purchaser understands that failure to file such an
election in a timely manner may result in adverse tax consequences for
Purchaser.  Purchaser further understands that an additional copy of such
election form should be filed with his or her federal income tax return for the
calendar year in which the date of this Agreement falls.  Purchaser acknowledges
that the foregoing is only a summary of the effect of United States federal
income taxation with respect to purchase of the Shares hereunder, and does not
purport to be complete.  Purchaser further acknowledges that the Company has
directed Purchaser to seek independent advice regarding the applicable
provisions of the Code, the income tax laws of any municipality, state or
foreign country in which Purchaser may reside, and the tax consequences of
Purchaser's death.

     9.  Market Standoff Agreement.  In connection with the initial public
         -------------------------
offering of the Company's securities and upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities,
Purchaser agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any Shares (other than those included
in the registration) without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not to exceed 180
days) from the effective date of such registration as may be requested by the
Company or such managing underwriters and to execute an agreement reflecting the
foregoing as may be requested by the underwriters at the time of the public
offering.

Reuters Holdings Switzerland SA

Switzerland

     In consideration of the purchase by Reuters Holdings Switzerland SA
(together with any affiliates with respect to which Reuters Holdings Switzerland
SA owns, directly or indirectly, 50% or more of the outstanding voting power and
which Reuters Holdings Switzerland SA may designate from time to time,
"Reuters") of 789,474 shares of Series C Convertible Preferred Stock of Moai
Technologies, Inc. (the "Company"), pursuant to a Stock Purchase Agreement dated
July 21, 1999, the Company and Reuters agree to the terms and obligations of
this letter agreement ("Agreement").

1.   PRODUCT AND TECHNOLOGY RIGHTS
     -----------------------------

     1.1  Development Plans.  Upon the request of Reuters given from time to
          -----------------
time and at reasonable intervals, the Company shall provide Reuters with a
written summary of current and future development plans and product and
technology roadmaps of the Company and each of its subsidiaries in existence
from time to time ("Subsidiaries"); provided, however, that the Company shall be
obligated to provide such information only to the extent the Company provides
such information generally to licensees of its beta or full customer release
products.

     1.2  Technology Call/MFN Pricing.
          ---------------------------

     The Company and each of its Subsidiaries shall provide Reuters with the
right and opportunity to license the Company's and each of its Subsidiary's beta
and full customer release products (including without limitation any new
versions or releases of such products) at the same time as the Company and its
Subsidiaries commence licensing such products to third parties; provided,
however, that the Company shall not be obligated to license any beta versions of
the Company's products to Reuters unless Reuters qualifies as a beta customer
using the Company's generally applicable criteria.

     In providing Reuters with the opportunity to license such products, the
Company and its Subsidiaries shall offer and make available to Reuters terms in
respect thereof that are no less favorable as a whole to Reuters than those
previously extended by the Company and its Subsidiaries to any other person
similarly situated and using the product, for a business purpose,  in a manner
and on a scale similar to the use contemplated by Reuters.
<PAGE>

2.   MOST FAVORED BIDDER.
     -------------------

     Each of the Company and Reuters agrees that in the event the Company or any
of its Subsidiaries seeks to obtain news or data feeds of the type currently
provided by Reuters to its customers which news or data feeds are intended for
use by the Company or any of its Subsidiaries internally or as part of a
commercial web site operated by the Company or any of its Subsidiaries, the
Company agrees to approach Reuters and negotiate in good faith an arrangement
under which the Company or any of its Subsidiaries would obtain such news or
data feeds from Reuters.  The objective of these discussions will be to have the
Company and its Subsidiaries obtain such news and data feeds from Reuters to the
extent such news and data feeds satisfy the Company's requirements and can be
obtained on terms that are as competitive as other commercially available
sources.

3.   STRATEGIC PARTNER.
     -----------------

     Except with respect to any partner or investor who, together with its
affiliates, is engaged primarily in the business of providing debt or equity
financing, the Company agrees that Reuters shall have a right of first offer
with respect to: (a) the issuance and sale for financing purposes to any person
(including any strategic or financial investor) other than the Company, and any
employees, officers, consultants or directors of any such subsidiary, of
securities of any subsidiary formed by the Company for the purpose of expanding
the Company's or any subsidiary's activities or operations into Europe or Asia,
or any part of either of the foregoing, and (b) the issuance and sale for
financing purposes to any person (including any strategic or financial investor)
other than the Company of any equity interest in any joint venture entity
(regardless of the form of such entity) formed by the Company for the purpose of
expanding the Company's or any subsidiary's activities or operations into Europe
or Asia (each an "Expansion Transaction").  The foregoing right of first offer
shall expire as to the issuance and sale of securities or equity interests by a
given subsidiary or joint venture entity if the Company and Reuters shall have
failed to reach agreement on mutually acceptable terms therefor within twenty
(20) days after the commencement of good faith negotiations thereof (which
negotiations shall commence within five days after the Company notifies Reuters
of the proposed Expansion Transaction), provided that the Company shall have
continued to negotiate in good faith with Reuters during the entirety of such
twenty (20) day period and provided further that each such twenty (20) day
period shall be reduced to five business days in the event the Company wishes to
explore the possibility of a similar arrangement with any third party in which
such third party has approached the Company and indicated its interest in
exploring such an arrangement (provided that such reduction in time shall not
apply if any such interest expressed by any third party was preceded by
solicitation by the Company of such interest).

4.   TERMINATION.
     -----------

     This Agreement shall terminate upon the earlier of (a) June 30, 2002, (b)
the closing of the sale, conveyance, or other disposition or encumbrance of all
or substantially all of the Company's assets or business or the merger into or
consolidation with any other entity (other than a wholly-owned subsidiary
corporation) or any other transaction or series of related transactions in which
at least fifty percent (50%) of the voting power of the Company is disposed

                                      -2-
<PAGE>

of (other than a merger effected exclusively for the purpose of changing the
domicile of the Company), (c) the date on which Reuters no longer owns at least
two percent of the Company's outstanding shares of Common Stock calculated
assuming the conversion and exercise of all outstanding convertible and
exercisable securities (without regard to any vesting requirements), and (d)
with respect to Section 3 only, the effective date of the Company's registration
statement filed under the Securities Act of 1933, as amended, for the sale of
its securities to the public at a public offering price of not less than $11.40
per share and which results in gross aggregate cash proceeds to the Company of
at least $20,000,000.

     5.   CONFIDENTIALITY.
          ---------------

     Reuters agrees to comply and cause all of its affiliates to comply with the
following confidentiality obligations.

     5.1. Definition of Confidential Information.  "Confidential Information"
          --------------------------------------
means any oral, written, graphic or machine-readable information including, but
not limited to, that which relates to patents, patent applications, research,
product plans, products, developments, inventions, processes, designs, drawings,
engineering, formulae, markets, software (including source and object code),
hardware configuration, computer programs, algorithms, future development plans
and product and technology roadmaps, business plans, agreements with third
parties, services, customers, marketing or finances of the Company or any
Subsidiary, which Confidential Information is designated in writing to be
confidential or proprietary, or if given orally, is confirmed in writing as
having been disclosed as confidential or proprietary within a reasonable time
(not to exceed thirty (30) days) after the oral disclosure, or which information
would, under the circumstances, appear to a reasonable person to be confidential
or proprietary.  Notwithstanding any failure to so identify it, all information
provided pursuant to Section 1 above shall be Confidential Information.

     5.2. Nondisclosure of Confidential Information.
          ------------------------------------------

          (a) Reuters agrees not to use any Confidential Information disclosed
to it by the Company or any of the Company's Subsidiaries for its own use or for
any purpose other than to determine whether or not to license the Company's
products.  Reuters shall not disclose or permit disclosure of any Confidential
Information of the Company to third parties or to employees of Reuters, other
than directors, officers, employees, consultants and agents of Reuters who are
required to have the information in order to determine whether or not to license
the Company's products. Reuters agrees that it shall take all reasonable
measures to protect the secrecy of and avoid disclosure or use of Confidential
Information of the Company and its Subsidiaries in order to prevent it from
falling into the public domain or the possession of persons other than those
persons authorized under this Agreement to have any such information.  Such
measures shall include, but not be limited to, the highest degree of care that
Reuters utilizes to protect its own Confidential Information of a similar
nature, which shall be no less than reasonable care.  Reuters further agrees to
notify the Company in writing of any actual or suspected misuse,
misappropriation or unauthorized disclosure of the Company's or any of its
Subsidiaries Confidential Information which may come to Reuters's attention.

                                      -3-
<PAGE>

          (b) Exceptions.  Notwithstanding the above, Reuters shall not have
              ----------
liability to the Company or any of its Subsidiaries with regard to any
Confidential Information which:

              (i)   was in the public domain at the time it was disclosed by the
Company or any of its Subsidiaries or has entered the public domain through no
fault of Reuters;

              (ii)  was known to Reuters, without restriction, at the time of
disclosure, as demonstrated by files in existence at the time of disclosure;

              (iii) is disclosed with the prior written approval of the
Company;

              (iv)  is independently developed by Reuters without use of any of
the Confidential Information; or

              (v)   is disclosed pursuant to applicable laws or regulations or
the order or requirement of a court, administrative agency, or other
governmental body; provided, however, that Reuters shall provide prompt notice
of such court order or requirement to the Company to enable the Company to seek
a protective order or otherwise prevent or restrict such disclosure.

     5.3. No Duplication; Return of Materials.  Reuters agrees, except as
          -----------------------------------
otherwise expressly authorized by the Company, not to make any copies or
duplicates of any Confidential Information.

     5.4. No Rights Granted.  Nothing in this Agreement shall be construed as
          -----------------
granting any rights under any patent, copyright or other intellectual property
right of the Company or any of its Subsidiaries, nor shall this Agreement grant
Reuters any rights in or to the Company's or any of its Subsidiaries'
Confidential Information.

6.   MISCELLANEOUS.

          -------------
accordance with the laws of the State of California.

     6.2  Counterparts.  This Agreement may be executed in counterparts, each of
          ------------
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

     6.3  Amendments and Waivers.  This Agreement may not be amended or modified
          ----------------------
without the written consent of Reuters and the Company, nor shall any waiver be
effective against any party unless in a writing executed on behalf of such
party.

     6.4. Severability.  If any provision of this Agreement shall be declared
          ------------
void or unenforceable by any judicial or administrative authority, the validity
of any other provision and of the entire Agreement shall not be affected
thereby.

     6.5  Other Obligations.  The Company represents and warrants that it has
          -----------------
not undertaken and covenants that neither it nor any subsidiary will undertake
any obligation to any

                                      -4-
<PAGE>

third party which would prohibit or conflict with the obligations undertaken to
Reuters in this clause.

     6.6  Equitable Relief.  Each of the Company  and Reuters acknowledges that
          ----------------
a breach by it of its obligations hereunder will cause irreparable harm to the

agrees, in the event of a breach or threatened breach by the other of the
provisions contained herein, that nonbreaching party shall be entitled, in
addition to all other available remedies, to an injunction restraining any
breach and requiring immediate performance hereunder, without the necessity of
showing economic loss and without any bond or other security being required.

                                      -5-
