correct any errors, omissions and/or inaccuracies in the transmission or
transcription of the CBS News Content identified by MarketWatch or reported to
MarketWatch by MarketWatch Site users.

                (d) Notwithstanding anything to the contrary contained herein,
upon notice from CBS, MarketWatch shall immediately cease using any CBS News
Content which (i) in CBS's sole opinion, conflicts, interferes with or is
detrimental to CBS's reputation or business or (ii) becomes subject to any third

infringement party's use of the infringing mark.

materials). MarketWatch will not authorize full scale production of any such
material until after obtaining CBS's written approval in each instance. Any

        5.1, calculation of Gross Revenues shall be made on a calendar yearly

                shall mean gross operating revenues (excluding the revenues

                the extent of any dividends or other distributions paid to
                MarketWatch or its subsidiaries, any Person in which MarketWatch
                or any of its subsidiaries has an interest, derived from the
                Core Business presented in accordance with generally accepted
                accounting principles and, if applicable, based on revenues as
                reported in the periodic quarterly and annual statements
                required by the Securities and Exchange Commission, provided
                that Gross Revenues shall not be reduced for royalties,
                commissions (except as otherwise set forth in clause
                5.1(b)(ii)(B) below) fees or other expenses incurred in
                generating such operating revenue. If an income statement of
                MarketWatch presents operating revenue net of any reductions not
                allowed under this Section 5, then for purposes of this
                paragraph 5.1, operating revenue as presented shall be increased
                by the amount of reductions. Sources of operating revenue
                include, but are not limited to, advertising, sponsorship,
                partnership/commerce, subscriptions, and sales of products and
                services and shall include all monetary consideration and the
                fair value of all non-monetary considerations. Sources of
                operating revenue shall not include: (I) revenue realized by
                MarketWatch pursuant to paragraph 1.2 of the DBC Services
                Agreement between DBC and MarketWatch dated as of October 27,
                1997, as amended and restated on January __, 1999 (the
                'Services Agreement') (i.e., the stated dollar portion of
                subscriber fees from various DBC-owned subscriber devices
                (including portable personal computers) and the stated
                percentage of Net Revenues (as defined in the Services
                Agreement) derived from the real-time market feeds currently
                known as MarketWatch Live and MarketWatch RT); (II) revenue
                realized from advertisements purchased by DBC from MarketWatch
                which advertise/promote DBC on the MarketWatch Site; (III)
                revenue realized from advertisements purchased by any third
                party advertising on the MarketWatch Site if and to the extent
                CBS determines that revenues from such Person should be excluded
                from the calculation of 'Gross Revenues' under this Section 
                5.1; and (IV) an amount equal to the total revenues (calculated
                in accordance with U.S. generally accepted accounting 
                principles) for the 12 months prior to the date of consummation
                of the acquisition of such Acquired Business. 
    

                              (B) Notwithstanding anything to the contrary
                contained in clause 5.1(b)(ii)(A) above, Gross Revenues may be
                reduced by the amount of any sales representative commission(s)
                paid by MarketWatch to any third party sales representative(s)
                not affiliated with MarketWatch and in which MarketWatch has no
                interest, not to exceed fifteen percent (15%) of the actual ad
                price in each instance. Additionally, Gross Revenues for any
                particular quarterly period shall not include revenues reported
                by MarketWatch as a result of revenues recognized prior to the
                effective date of the acquisition of an entity acquired by
                MarketWatch and accounted for as a pooling of interest
                transaction.

        5.2 In the event that the rights granted by CBS to MarketWatch pursuant
to this Agreement cause CBS to recognize income for federal income tax


                                       7


purposes in an amount which exceeds the amount prescribed for such rights in
paragraph 5.1 above (the 'Excess'), then the entire amount of any deductions
available to MarketWatch solely attributable to such Excess shall be allocated
by MarketWatch to CBS.

6. ACCOUNTINGS

        6.1 MarketWatch will compute Gross Revenues as of each March 31, June
30, September 30 and December 31 for the prior three (3) months. Within
ninety-five (95) days after the fourth calendar quarterly period and within
forty-five (45) days after each of the first three (3) calendar quarterly
periods concerned, MarketWatch will send CBS a statement covering Gross Revenues
and will pay CBS CBS's share of Gross Revenues due. Acceptance by CBS of any
statement or payment shall not preclude CBS from challenging the accuracy
thereof.

        6.2 MarketWatch will maintain accurate books and records which report
the recognition of Gross Revenues. CBS may, at its own expenses, examine and
copy those books and records, as provided in this paragraph. CBS may make such
an examination for a particular statement within three (3) years after the date
when the other party sends the examining party the statement concerned.
(MarketWatch will be deemed conclusively to have sent CBS the statement
concerned on the date prescribed in paragraph 6.1, unless CBS notifies
MarketWatch otherwise with respect to any statement, within ninety (90) days
after that date). CBS may make those examinations only during MarketWatch's
usual business hours, and at the place where it keeps the books and records.
Such books and records shall be kept at the MarketWatch office in San Francisco,
California, unless otherwise notified. CBS will be required to notify
MarketWatch at least ten (10) days before the date of planned examination. If
CBS's examination has not been completed within two months from the time CBS
begins it, MarketWatch may require CBS to terminate it on seven (7) days notice
to CBS at any time, provided that MarketWatch has cooperated with CBS in the
examination of such books and records.

necessary, at the other party's request and expense, to protect the other's
respective rights, titles, and interests specified in this Article 7, and
further agrees to execute any documents that might be necessary to perfect each
party's ownership of such rights, titles, and interests.

authorize another to license any Person other than MarketWatch the right to use

thereof.

        9.3 Either Party may exercise its right to terminate pursuant to this
Section 9 by sending the other party appropriate notice. No exercise by CBS of
its rights under this Section 9 will limit CBS's remedies by reason of
MarketWatch's default, CBS's rights to exercise any other rights under this
Section 9, or any of CBS's other rights. No exercise by MarketWatch of its
rights under this Section 9 will limit MarketWatch's remedies by reason of CBS's
default, MarketWatch's rights to exercise any other rights under this Section 9,
or any of Marketwatch's other rights.

        that the fading is due to the photostatic process, then the card is
        acceptable .
