                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                   (UNAUDITED)

NOTE 1 -- ORGANIZATION AND NATURE OF BUSINESS

BASIS OF PRESENTATION

        The accompanying unaudited condensed consolidated financial statements
reflect all adjustments that, in the opinion of management, are necessary for a
fair presentation of the results for the periods shown. The results of
operations for such periods are not necessarily indicative of the results
expected for a full year or for any future period. These financial statements
should be read in conjunction with the financial statements and related notes
included in the Company's Annual Report on Form 10-K for the year ended December
31, 1998 as amended by Form 10-K/A. Additionally, certain items previously
reported in specific financial statement captions have been reclassified to
conform with the current presentation.

THE COMPANY

        MarketWatch.com, Inc. (the "Company"), a leading Web-based provider of
comprehensive, real-time, business news, financial programming and analytic
tools, was formed on October 29, 1997 in the state of Delaware as a limited
liability company and was jointly owned by Data Broadcasting Corporation ("DBC")
and CBS Broadcasting Inc. ("CBS") (collectively, the "Members"), with each
Member owning a 50% interest in the Company.

        In connection with the formation of the limited liability company, the
Company, CBS and DBC entered into a contribution agreement on October 29, 1997
(the "Contribution Agreement"), under which DBC contributed to the Company $1.0
million in cash upon consummation of the Contribution Agreement, $1.0 million in
cash on October 29, 1998 and DBC's existing "Online/News" business which
primarily consisted of customer contracts and intellectual property in return
for its ownership interest. CBS agreed to provide $50.0 million of rate card
amount advertising and promotions over a period of five years in return for its
ownership interest. Under the terms of the Stockholders' Agreement, the $50.0
million rate card amount was revised to $30.0 million upon completion of the
Company's initial public offering (see Note 3).

        In addition, CBS and the Company entered into a license agreement dated
October 29, 1997 (the "License Agreement") under which CBS, in exchange for 30%
of net advertising revenue, as defined, granted to the Company the non-exclusive
right and license to use certain CBS news content and registered trademarks,
including the CBS "Eye" design, for five years ending October 29, 2002, subject
to termination on the occurrence of certain events. In addition to the
agreements above, the Company entered into a services agreement with DBC (the
"Services Agreement"). Under the terms of the Services Agreement, DBC charged
the Company for certain general services and the Company receives payment from
DBC for supplying news and receives a fee for licensing MarketWatch RT(TM)and
MarketWatch Live(TM).

        In January 1999, the Company completed an initial public offering
("IPO") of 3,162,500 shares of common stock at $17 per share. Total proceeds to
the Company were approximately $48.2 million, net of offering costs. Immediately
prior to the completion of the IPO, the Company was reorganized from a limited
liability company to a corporation. All share and per share data have been
retroactively adjusted to reflect the reorganization.

        Effective June 9, 1999, the Company completed its acquisition of
BigCharts.com, Inc. ("BigCharts"), a Minnesota corporation, in a merger
transaction for $6.0 million in cash, $110.9 million worth of MarketWatch.com
common stock, and $38.6 million worth of options to purchase MarketWatch.com
common stock which are issuable upon exercise of options to purchase BigCharts
common stock assumed in the merger. BigCharts, based in Minneapolis, is a
leading provider of licensed online financial charting content to electronic
brokers, financial publishers and portals (see Note 6).

NOTE 2 -- REVENUE RECOGNITION

        Advertising revenue is recognized in the month earned from advertising
contracts in which the Company guarantees a minimum number of impressions (a
view of an advertisement by a consumer) for a fixed fee. Additionally, certain
sponsorship agreements provide links to third-party web sites and generate
either fixed transaction fees for monthly access or variable fees which are
dependent upon the number of transactions consummated in the third-party web
site by linked customers.

        Revenue related to the sale of news is recognized in the month the
services are provided.

        License revenue is recognized based on contracts in which (1) the
customer pays a fixed amount in exchange for access to the content for a
specified period of time or (2) a customer pays a monthly fee based on the
number of subscribers to their site who have access to the content. Revenue from
fixed fee agreements is recognized ratably over the term of the agreement.
Subscriber agreement fees are recognized based on the number of monthly
subscribers who use the customer's website.

        Subscription revenues are charged to customers' credit cards and are
billed in advance on a monthly basis. Revenue from subscriptions is recognized
ratably over the subscription period.  Deferred revenues relate to subscription
fees for which amounts have been collected but for which revenue has not been
recognized.

        Revenues are recognized in the month earned provided that no
significant Company obligations remain and collection of the resulting
receivable is probable.

        Revenues from barter transactions are recognized in accordance with the
provisions of Accounting Principles Board Opinion No. 29 ("APB 29"). The
Company has entered into transactions with certain customers to barter
advertising space and content during the nine months ended September 30, 1999.
The Company has not recorded revenue or related expense for these transactions
since the value cannot be objectively determined with any degree of reliability.


NOTE 3 -- AGREEMENTS WITH CBS AND DBC

        In January 1999, the Company entered into a Stockholders' Agreement
("Stockholders' Agreement"). Under the terms of the Stockholders' Agreement, CBS
reduced the advertising commitment from the Contribution Agreement to an
aggregate rate card amount of $30.0 million in return for a change in the
royalty rate payable under the License Agreement, extension of the License
Agreement to 2005 and modification to certain non competition provisions.
Additionally, both CBS and DBC will have a right of first refusal in the event
either party desires to sell any securities of the Company to a third party or
if the Company issues new securities.

        In January 1999, the Company and CBS entered into an Amended and
Restated License Agreement (the "Amended and Restated License") that superseded
and replaced the License Agreement. The Amended and Restated License became
effective immediately prior to the IPO. Under the Amended and Restated License,
in return for the right to use the CBS name and logo as well as the CBS
Television Network news content, the Company will be obligated to pay a royalty
to CBS of: (i) during 1999, (A) 8% of Gross Revenues in excess of $500,000 and
up to and including $50.5 million and (B) 6% of Gross Revenues in excess of
$50.5 million, and



<PAGE>   7

(ii) in subsequent years through the termination of the License Agreement on
October 29, 2005, (A) 8% of Gross Revenues up to and including $50.0 million and
(B) 6% of Gross Revenues in excess of $50.0 million. CBS will have the right to
terminate the agreement in certain circumstances, including breach of a material
term or condition of the agreement, insolvency, bankruptcy or other similar
proceeding, discontinuance of use of the MarketWatch logo without providing an
acceptable substitute, or acquisition or issuance of certain percentages of the
Company's common stock or voting power by or to a CBS competitor. In addition,
CBS will retain significant editorial control over the use and presentation of
the CBS news content and the CBS logo and has the ability to prevent the Company
from displaying certain types of content, which are unacceptable to CBS. The
Amended and Restated License will expire on October 29, 2005.

        Gross Revenues means gross operating revenues that are derived from an
Internet service or Web site that:

        -       provides information or services of a financial nature; or

        -       uses the CBS trademarks licensed to MarketWatch.com.

Gross Revenues excludes revenues from DBC, an amount equal to certain
commissions paid to sales representatives and an amount equal to certain
revenues attributable to an acquired company's results of operations for the 12
months prior to the acquisition.

        The terms of the Amended and Restated License will not prohibit CBS from
licensing its name and logo to another Web site or Internet service that does
not have as its primary function and its principal theme and format the
delivering of comprehensive real-time or delayed stock market quotations and
financial news in the English language to consumers. CBS is also not prohibited
from licensing its news content to, or investing in, another Web site or
Internet service.

        In January 1999, the Company and DBC entered into an Amended and
Restated Services Agreement (the "Amended Services Agreement"), which supersedes
and replaces the Services Agreement. Under the Amended Services Agreement, DBC
will provide the Company with hosting services, software programming assistance,
data feeds, communications lines, office space and related facilities, network
operations and Web site management services as well as certain administrative
and engineering services if requested by the Company. The Amended Services
Agreement provides for DBC to grant the Company certain nonexclusive licenses to
its data and information feeds and provides for certain network Web site hosting
performance standards. DBC will also pay the Company a monthly per subscriber
fee ranging from $2.50 to $5.00, subject to a monthly minimum of $100,000
through October 2002, for delivery of the Company's news to all DBC subscribers,
as defined. The Company is also required to pay DBC 25% and 75% of subscription
revenues for MarketWatch RT(TM) and MarketWatch Live(TM), respectively. The term
of the Amended Services Agreement will expire on October 29, 2005.

        In January 1999, the Company and DBC entered into a Revolving Credit
Agreement (the "Credit Agreement") whereby DBC will be obligated to loan the
Company up to $5.0 million through October 2000. Borrowings under the Credit
Agreement will be unsecured and bear interest at a variable rate per annum equal
to The Chase Manhattan Bank's prime rate plus 2%. All previous advances from DBC
under the Limited Liability Company Agreement of the LLC between CBS and DBC
(the "LLC Agreement") were included against the borrowings under the Credit
Agreement. As of September 30, 1999 the Company had no outstanding borrowings
under the Agreement.

        In January 1999, the Company, CBS and DBC entered into a Registration
Rights Agreement ("Registration Agreement"). CBS and DBC, and their affiliates
and permitted transferees will have certain registration rights for the
securities of the Company held by them under the Registration Agreement.

NOTE 4 -- COMPREHENSIVE NET INCOME (LOSS)

        Comprehensive net income (loss) is comprised of net loss and other
comprehensive earnings such as unrealized gains or losses on available-for-sale
marketable securities. The Company's total comprehensive net losses were as
follows:

NOTE 5 -- NET LOSS PER SHARE



<PAGE>   8

        Basic net loss per share is computed using the weighted average number
of shares of common stock. Diluted net loss per share is computed using the
weighted average number of shares of common stock and common equivalent shares
outstanding during the period. Common equivalent shares consist of stock options
(using the treasury stock method). Common equivalent shares are excluded from
the computation if their effect is anti-dilutive.

        Options to purchase 1,691,557 and 866,000 shares of common stock were
outstanding at September 30, 1999 and 1998, respectively, but were not included
in the computation of diluted net loss per share because either the options'
exercise price was greater than the average market price of the common shares
during the period or inclusion of such options would have been anti-dilutive.

NOTE 6 -- BUSINESS ACQUISITIONS

        On June 9, 1999, MarketWatch.com completed its acquisition of BigCharts
for $6.0 million in cash, shares of MarketWatch.com common stock and assumed
options to purchase MarketWatch.com common stock valued at $110.9 million and
$38.6 million. The transaction was accounted for using the purchase method;
accordingly, the purchase price was allocated to the assets acquired and
liabilities assumed based on their fair market values at the date of
acquisition. The results of operations and assets of Big Charts were reflected
on the Company's financial statements commencing June 1, 1999. BigCharts, based
in Minneapolis, is a leading provider of licensed online financial charting
content to electronic brokers, financial publishers and portals. It is one of
the most heavily trafficked financial sites and an industry-leading provider of
objective, data-driven online financial content for self-directed investors. The
Company recorded acquisition expenses of $2.0 million in connection with the
acquisition in the second quarter of 1999. The $2.0 million primarily consisted
of accounting and legal fees and other related transactions costs. The following
are unaudited pro forma condensed consolidated results of operations for the
Company and BigCharts presented on the basis that the acquisition had taken
place and the related charges, noted above, were recorded at the beginning of
each of the periods presented. These results are not indicative of the actual
results that would have occurred had the transaction taken place at the
beginning of the period:

</TABLE>

The Company assesses the recoverability of its long term assets by comparing
the projected undiscounted net cash flows associated with those assets against
their respective carrying amounts. Impairment, if any, is based on the excess of
the carrying amount over the fair value of those assets. If it became probable
that the projected future undiscounted cash flows of acquired assets were less
than the carrying


<PAGE>   9

value of the goodwill, we would recognize an impairment loss in accordance with
the provisions of SFAS No. 121. No impairment has been identified to date.

NOTE 7 -- AMERICA ONLINE AND YAHOO!

        In September 1999, we entered into a three-year distribution agreement
with America Online, Inc. ("AOL") to be AOL's premiere provider of business and
financial news for AOL's network including AOL's proprietary service, AOL.com,
CompuServe and Netscape (collectively, "AOL Members"). Under the agreement, we
will create a co-branded site that will enable AOL Members to access
MarketWatch.com content and investment management tools through the AOL portal.
The Company and AOL have also agreed to collaborate in sales and marketing
efforts.

        In August 1999, the terms of the YAHOO! agreement were amended. Under
the terms of the amended agreement, we have extended the terms to include
additional advertising and slotting fees of $1.6 million over a twelve month
period beginning on January 1, 2000.

</TABLE>

        A majority of the expenditures and liabilities charged by DBC to the
Company were incurred by DBC and directly charged or allocated to the Company.
The expenses which were paid on behalf of the Company by DBC totaled $72,000 and
$3.1 million for the three-month periods ended September 30, 1999 and 1998 and
$2.1 million and $6.2 million for the nine-month periods ended September 30,
1999 and 1998, respectively. Direct charges primarily consist of payroll and
related costs, consulting, commissions and access fees for information from
various exchange markets. Allocated charges totaled $455,000 and $177,000 for
the three-month periods ended September 30, 1999 and 1998 and $1.1 million and
$517,000 for the nine-month periods ended September 30, 1999 and 1998,
respectively, and related to general services that include cash management,
accounting, network operations and hosting of the Company's web pages and data
feeds provided pursuant to the Amended and Restated Services Agreement. Charges
for these services and equipment usage are allocated based upon DBC's estimate
of costs attributable to the operations of MarketWatch.com.

        Direct charges for subscription revenues for MarketWatch Live and
MarketWatch RT were $58,000 and $40,000 for the three-month periods ended
September 30, 1999 and 1998 and $171,000 and $117,000 for the nine-month periods
ended September 30, 1999 and 1998, respectively. News revenues are based on the
number of DBC subscribers and were $413,000 and $322,000 for the three-month
periods ended September 30, 1999 and 1998 and $1.2 million and $949,000 for the
nine-month periods ended September 30, 1999 and 1998, respectively. Included in
accounts receivable at September 30, 1999 is $284,000 owed to the Company by
DBC.

        The Company has recorded advertising expenses of $9.6 million and $5.0
million at rate card value for the nine months ended September 30, 1999 and
1998, respectively, for advertising and promotion provided by CBS.

        The Company has recorded $115,000 in news revenue for the nine months
ended September 30, 1999 for the CBS MarketWatch Weekend television show sold to
CBS. Costs associated with the show are included in advertising and news costs
of sales.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

        This report contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21e of the Securities
Exchange Act of 1934, including, without limitation, statements regarding the
Company's expectations, beliefs, intentions or future strategies that are
signified by the words "expects", "anticipates", "intends", "believes", or
similar language. All forward-looking statements included in this document are
based on information available to the Company on the date hereof, and the
Company assumes no obligation to update any such forward-looking statements.
Actual results could differ materially from those projected in the
forward-looking statements. In evaluating the Company's business, prospective
investors should carefully consider the information set forth below under the
caption "Factors That May Affect Future Operating Results" in addition to the
other information set forth herein. The Company cautions investors that its
business and financial performance are subject to substantial risks and
uncertainties.

OVERVIEW

        MarketWatch.com is a leading Web-based provider of comprehensive,
real-time business news, financial programming and analytic tools. In addition
to real-time coverage of business and financial news and in-depth commentary on
market moving trends and events, we offer stock quotes, portfolios, charts and
fundamental data. We completed our initial public offering on January 15, 1999.
Prior to the offering, MarketWatch.com was a joint venture owned 50% each by DBC
and CBS, and was formed as a limited liability company (the "LLC") in October
1997. We were formed as the successor to DBC's Online/News Business, which
commenced operations in October 1995. When this joint venture was formed, CBS
and DBC agreed that their contributions would be treated as having equal value.
Immediately prior to the closing of our initial public offering on January 15,
1999, we were re-organized from a limited liability company into a corporation.

        Since we were formed as an LLC, MarketWatch.com has operated as a
provider of business news, financial programming and analytic tools, with
services including news articles, feature columns and analytic tools, such as
stock quotes and charting. These services are available free of charge.
MarketWatch.com has continued selling advertising banners and sponsorships on
its Website and subscriptions to MarketWatch RT, MarketWatch Live and news to
DBC and others.

        Although MarketWatch.com sells MarketWatch RT and MarketWatch Live on a
non-exclusive basis, DBC may provide these services itself or through other
third parties. However, DBC is not permitted to sell advertising on a Web site
that has as its primary function and principal theme and format the delivery of
comprehensive stock quotes and financial news in the English language to
consumers. However, DBC could compete with us in the future.

        Our revenue has grown recently and our ability to generate significant
revenue in the future is uncertain. Further, in view of the rapidly evolving
nature of our business and our very limited operating history, we have little
experience forecasting our revenues. Therefore, we believe that period-to-period
comparisons of our financial results are not necessarily meaningful and you
should not rely upon them as an indication of our future performance. To date,
we have incurred substantial costs to create, introduce and enhance our
services, to develop content, to build brand awareness and to grow our business.
As a result, we have incurred operating losses in each fiscal quarter since we
were formed. We expect operating losses and negative cash flows to continue for
the foreseeable future as we intend to significantly increase our operating
expenses to grow our business. Because of non-cash charges in connection with
our acquisition of BigCharts, we also expect to incur net losses. We may also
incur additional costs and expenses related to content creation, technology,
marketing or acquisitions of businesses and technologies to respond to changes
in our rapidly changing industry. These costs could have an adverse effect on
our future financial condition or operating results.

        Immediately prior to the closing of our initial public offering in
January 1999, our agreements with CBS and DBC were amended so that:

        - CBS will contribute $30.0 million in rate card advertising through
        October 2002 instead of $50.0 million,

        - our license agreement with CBS was extended for three years to October
        29, 2005,

        - the royalties payable to CBS were modified from 30% of advertising
        revenue to approximately 8% of all of our revenue other than revenue
        attributable to DBC and certain other revenue, and



<PAGE>   12

        - DBC's service obligation was extended three years to October 29, 2005.
        However, the Subscriber Payments obligation will expire in October 2002.
        In addition, we will not receive any Subscriber Payments with respect to
        certain commercial subscribers.

        Effective June 9, 1999, MarketWatch.com completed its acquisition of
BigCharts, for $6.0 million in cash, shares of MarketWatch.com common stock and
assumed options to purchase MarketWatch.com common stock valued at $110.9
million and $38.6 million. BigCharts, based in Minneapolis, is a leading
provider of licensed online financial charting content to electronic brokers,
financial publishers and portals. It is one of the most heavily trafficked
financial sites and an industry-leading provider of objective, data-driven
online financial content for self-directed investors. The Company believes that
the acquisition of BigCharts provides (1) additional analytical tools for
existing MarketWatch.com users, (2) increased customer base for the
MarketWatch news content and (3) increased inventory for advertising. The
Company's expenses will increase in future periods to reflect the costs
associated with the operations of the BigCharts website.

RESULTS OF OPERATIONS

NET REVENUES

        Net revenues are primarily derived from the sale of advertising on our
web site, license of BigCharts charting content, subscription sales from
MarketWatch RT and MarketWatch Live, and the sale of news to DBC, CBS and other
clients. Net revenues increased by 287% to $7.0 million for the three months
ended September 30, 1999 from $1.8 million for the three months ended September
30, 1998, and increased 232% to $14.9 million for the nine months ended
September 30, 1999 from $4.5 million for the nine months ended September 30,
1998. The increases in total net revenues are due primarily to the increases in
the number of ads placed on our web sites, the license revenue associated with a
full quarter of the licensing of BigCharts content and the introduction of the
CBS MarketWatch Weekend television show in September 1999. The increases in
advertising revenues were caused by several interrelated factors, including the
following:

        - increased number of advertisers;

        - increased users on our Web site and resultant page views with
        advertisements contained on those pages;

        - increased inventory available for sale on the BigCharts site as a
        result of the acquisition;

        - increased size and productivity of our direct sales force; and

        - increased flexibility and sophistication of advertising packages
        offered to advertisers

        Substantially all of our advertising customers purchase advertising
under short-term contracts. Customers can cease advertising on short notice
without penalty. Advertising revenues would be adversely affected if we were
unable to renew advertising contracts with existing customers or obtain new
customers. We expect to continue to derive a majority of net revenues from
selling advertisements. The market for Web advertising is intensely competitive,
and advertising rates could be subject to pricing pressure in the future. If we
are forced to reduce our advertising rates or we experience lower CPM's (cost
per thousand page views) across our Web site or lower click-through advertising
rates as a result of such competition or otherwise, future revenues could be
adversely affected.

COST OF REVENUES

        Cost of revenues primarily consists of costs related to advertising and
news including compensation, royalties payable to CBS and content providers,
amortization of intangibles associated with the purchase of BigCharts, web site
infrastructure costs allocated from DBC and costs of serving ads by DoubleClick,
costs related to license revenue including communication lines, and costs
related to subscriptions including exchange fees and communication lines. Cost
of revenues increased by 213% to $2.7 million for the three months ended
September 30, 1999 from $873,000 for the three months ended September 30, 1998,
and increased 236% to $6.1 million


<PAGE>   13

for the nine months ended September 30, 1999 from $1.8 million for the nine
months ended September 30, 1998. Cost of news and advertising revenues increased
due to the addition of news reporters and editors, additional network
communications lines to accommodate increased traffic on our web sites,
DoubleClick costs to serve advertisements on the site, amortization of
intangibles, and royalties paid to CBS. Royalties to CBS were $418,000 and $0
for the three months ended September 30, 1999 and 1998, respectively and
$799,000 and $0 for the nine months ended September 30, 1999 and 1998,
respectively. Cost of licensing revenues increased due to the addition of
BigCharts and cost of subscription revenues increased as more users subscribed
to MarketWatch.com services in comparison to the third quarter of the prior
year. As a percentage of net revenues, cost of revenues were 39% and 49% for the
three months ended September 30, 1999 and 1998, respectively, and 41% for the
nine months ended September 30, 1999 and 1998. For the quarter, the decrease as
a percentage of net revenues is due to the addition of licensing revenue from
BigCharts in excess of the corresponding increase in licensing expense and an
increase in advertising revenue in excess of the associated increases in
headcount and other costs. For the nine-month periods, costs of revenues have
increased at the same incremental rate as revenue due to an increase in
compensation for additional editorial staff and increases in overall headcount
necessary to support revenue growth. We expect cost of revenues in absolute
dollars to increase in the future as a result of royalties payable to CBS as we
have exceeded the royalty exempt revenue level of $500,000 in our license
agreement with CBS. In addition, we intend to increase the number of editorial
staff in the future, which will lead to an increase in cost of revenues.

PRODUCT DEVELOPMENT

        Product development expenses primarily consist of license fees for
content, compensation for software developers and expenses for contract
programmers and developers. Product development expenses increased by 283% to
$1.6 million for the three months ended September 30, 1999 from $429,000 for the
three months ended September 30, 1998, and increased 201% to $3.1 million for
the nine months ended September 30, 1999 from $1.0 million for the nine months
ended September 30, 1998. Product development expenses increased due to the
hiring of additional employees, the purchase of BigCharts and associated
expenses and the amortization of deferred compensation for development personnel
in the first three quarters of 1999. Product development expenses were 24% of
net revenues for the three months ended September 30, 1999 and 1998 and 21% and
23% for the nine months ended September 30, 1999 and 1998, respectively. Product
development costs remained constant for the quarter and decreased for the nine
months as a percentage of net revenues as a result of increased net revenues.

GENERAL AND ADMINISTRATIVE

        General and administrative expenses primarily consist of compensation
for finance, business development and administrative personnel, allocations from
DBC for administrative services, occupancy costs, professional fees,
depreciation charges and charges for bad debt. General and administrative
expenses increased by 190% to $2.5 million for the three months ended September
30, 1999 from $845,000 for the three months ended September 30, 1998, and
increased 196% to $6.2 million for the nine months ended September 30, 1999 from
$2.1 million for the nine months ended September 30, 1998. General and
administrative expenses in absolute dollars increased due primarily to costs
related to the acquisition of BigCharts as well as travel expenses, directors
and officers liability insurance expense, and professional service fees
associated with the acquisition. To a lesser extent, costs increased due to
increased headcount, occupancy, legal and consulting expenses as well as costs
associated with the amortization of deferred compensation in the first three
quarters of 1999. We hired additional personnel and incurred additional costs
related to being a public company. As a percentage of net revenues, general and
administrative costs were 35% and 47% for the three months ended September 30,
1999 and 1998, respectively and 42% and 47% for the nine months ended September
30, 1999 and 1998, respectively. As a percentage of net revenues, general and
administrative expenses decreased for the quarter and nine-month period as net
revenues increased at a higher rate than the expenses. We believe that the
absolute dollar level of general and administrative expense will increase in
future periods as a result of an increase in personnel to support the Company's
larger operations particularly related to the acquisition of BigCharts.

SALES AND MARKETING

        Sales and marketing expenses primarily consist of promotion and
advertising provided by CBS, online and offline advertisements, advertising
commissions, promotional materials, compensation and sales commissions to our
direct sales force. Sales and marketing expenses increased by 135% to $7.5
million for the three months ended September 30, 1999 from $3.2 million for the
three months ended September 30, 1998, and increased 188% to $22.0 million for
the nine months ended September 30, 1999 from $7.6 million for the nine months
ended September 30, 1998. Sales and marketing expenses increased in absolute
dollars during the quarter and nine-month period due to a number of factors
including:

        - increase in amortization of promotions and advertising contributed by
        CBS in the first three quarters of 1999;

        - growth of our direct sales force in the first three quarters of


<PAGE>   14

        1999 and increased sales commissions from higher advertising sales;

        - increased purchases of Web banner ads to promote our products and
        services;

        - payments for the CBS MarketWatch Weekend television show promotion;

        - increased purchases of traditional print and broadcast advertising in
        1999 to promote our products and services; and

        - increased payments to distribution partners in 1999.

        We record an expense at the time the advertising and promotion is
provided by CBS under the Amended and Restated License Agreement based on the
rate card value of the advertising. We recorded non-cash advertising expense of
$2.7 million and $1.6 million at the rate card value for the three months ended
September 30, 1999 and 1998, respectively, and $9.6 million and $5.0 million for
the nine months ended September 30, 1999 and 1998, respectively, related to
services provided by CBS. We have recorded aggregate non-cash advertising
expense of $16.6 million of the $30.0 million CBS has agreed to provide. As a
percentage of net revenues, sales and marketing expenses were 108% and 177% for
the three months ended September 30, 1999 and 1998 and 147% and 170% for the
nine months ended September 30, 1999 and 1998, respectively. Sales and Marketing
expense as a percentage of net revenues decreased for the quarter and nine-month
period due to a planned hold on spending in 1999 during the historically
low-volume trading months of July and August and as a result of increased
revenue.

        We anticipate that sales and marketing expenses in absolute dollars will
increase in future periods as we continue to pursue an aggressive brand-building
strategy through advertising and distribution and continue to build our direct
sales organization.

PURCHASED IN-PROCESS RESEARCH AND DEVELOPMENT

        Of the $157.5 million purchase price for BigCharts, $200,000 was
allocated to in-process research and development, which was expensed in full
upon completion of the acquisition in June 1999.

AMORTIZATION OF GOODWILL AND INTANGIBLES

        Of the $157.5 million purchase price for BigCharts, $152.5 million was
allocated to goodwill, which is being amortized over 3 years, and $3.6 million
was allocated to intangible assets, which are being amortized over periods
ranging from 1.5 to 3.5 years. Amortization of goodwill and intangibles for the
three and nine months ended September 30, 1999 was $13.0 million and $17.5
million, respectively.

INTEREST INCOME (EXPENSE)

        Interest income of $222,000 for the three months ended September 30,
1999 and $949,000 for the nine months ended September 30, 1999 resulted from
interest income on the proceeds from our IPO. Interest expense of $54,000 and
$75,000 for the three and nine months ended September 30, 1998 resulted from
borrowings from DBC.

LIQUIDITY AND CAPITAL RESOURCES

        Our cash, cash equivalents and short-term investments totaled $19.7
million at September 30, 1999, representing 12% of total assets compared to
$140,000 at December 31, 1998 due to the inflow of cash from our initial public
offering in the first quarter of 1999. We have invested our cash in excess of
current operating requirements in investment grade securities. The investments
have variable and fixed interest rates and primarily short-term maturities. In
accordance with Statements of Financial Accounting Standards 115, "Accounting
for Certain Investments in Debt and Equity Securities" these investments are
classified as "available for sale".

        Cash used in operating activities was $14.6 million and $2.9 million
for the nine months ended September 30, 1999 and 1998, respectively. Cash
outflow in 1999 is primarily the result of a net loss of $38.9 million, offset
by non cash charges of $9.6 million for advertising provided by CBS, $17.5
million in amortization of goodwill and intangibles, and a write-off of
in-process research and development related to the acquisition of BigCharts of
$200,000. Significant uses of cash in operations for the nine months ended
September 30, 1999 include costs associated with increased sales and marketing
activities to establish and promote our products and services and payments to
distributors and advertisers.


<PAGE>   15

        Cash used in investing activities was $15.5 million and $889,000 for
the nine months ended September 30, 1999 and 1998, respectively. Cash was used
in the current year primarily for the purchase of BigCharts and short term
investments, and for capital expenditures. The BigCharts purchase included a
cash payment of $6.0 million to stockholders and financial advisors of
BigCharts, and $1.5 million in acquisition related costs. Capital expenditures
have generally consisted of purchases of computer hardware and leasehold
improvements related to leased facilities and are expected to increase in future
periods. We have experienced a substantial increase in capital expenditures and
operating lease arrangements since inception, which is consistent with increased
staffing, and we anticipate that this will continue in the future.

        Cash provided by financing activities were $44.2 million and $3.8
million for the nine months ended September 30, 1999 and 1998, respectively.
Cash inflow was generated by the initial public offering completed in
January of 1999 of 3,162,500 shares of common stock at $17 per share with
proceeds of $43.9 million net of underwriting and offering expenses and the
repayment of amounts owed to DBC.

        We have entered in to certain agreements with Yahoo! and AOL to make
payments for advertising and slotting over the next three years. In addition, we
are obligated to pay Yahoo! a fee based on the amount of traffic directed to our
Web site. At September 30, 1999 a total of $9.1 million will be paid in
fulfillment of these commitments over the next three years.

        To date, we continue to be substantially dependent on DBC for much of
our financial and operational services and related support functions. We believe
the implementation of an independent accounting system, financial, operational
and management controls, and reporting systems and procedures will be necessary
to support the continued expansion of our operations. As a consequence, we
intend to expend working capital to support the development of infrastructure.

        Under the terms of the LLC Agreement between CBS and DBC and,
subsequently, the Credit Agreement between MarketWatch.com and DBC, DBC agreed
to advance us up to an aggregate of $5.0 million on a revolving basis through
October 29, 2000. Borrowings will bear interest at a variable rate per annum
equal to The Chase Manhattan Bank's prime rate plus 2% and are due on October
29, 2000. As of September 30, 1999, there were no advances from DBC under this
Credit Agreement. We used a portion of the net proceeds from our initial public
offering to repay all outstanding advances from DBC.

        We expect to incur significantly higher costs in the future to grow our
business, as a result of our acquisition of BigCharts, content creation costs,
and sales and marketing costs. We believe that the net proceeds from our initial
public offering, together with cash from operations, will be sufficient to meet
our anticipated cash needs for working capital and capital expenditures for at
least the next 12 months. We may need to raise funds sooner if we acquire any
additional businesses, products or technologies. If additional funds were raised
through the issuance of equity securities, the percentage ownership of our
then-current stockholders would be reduced. However, if CBS or DBC elects to
maintain their percentage interest pursuant to the exercise of the purchase
right they have under the stockholders' agreement between them and us, then CBS
or DBC would not necessarily suffer a reduction in their ownership. Furthermore,
such equity securities might have rights, preferences, or privileges senior to
those of our common stock.

YEAR 2000 READINESS

        DBC. We rely on DBC's information systems for customer billing,
accounting and administration as well as DBC's servers and personnel for Web
site hosting. DBC has advised us that it has substantially completed a
comprehensive review of its products, information systems and critical suppliers
for Year 2000 compliance, and has reported that its computer and communications
networks are Year 2000 compliant. In addition, the DBC servers host the
MarketWatch.com Web site. Any disruption in the functionality of the servers
could adversely affect services provided to our users. DBC's Y2K status is as
follows:

-       The Company has sought compliance statements from each of its
        significant suppliers, most of which have provided positive assurances
        regarding their compliance. DBC will continue to work with those who are
        not yet Y2K compliant.

-       In the normal course of business, DBC is replacing its administrative
        systems for accounting, billing and customer management.

        The new systems will be fully Y2K compliant. Implementation of new
systems include substantial new functionality in addition to being Y2K
compliant.

        Third-Party Suppliers. DBC and MarketWatch.com utilize software and
computer equipment from third party suppliers. DBC and MarketWatch.com also rely
on information, provided electronically by a number of outside suppliers. Based
on representations received from suppliers and completed and ongoing compliance
testing, DBC has advised us that its critical suppliers are or will be Year 2000
compliant in all material respects before the Year 2000. Based on
representations from our other software and equipment suppliers, we believe that
our software and other computer hardware is Year 2000 compliant. These third
party suppliers have represented that the software used to serve the BigCharts
sites are Year 2000 compliant. We also rely on solutions provided by DoubleClick
for the delivery of our advertising and user measurement. We have been informed
by them that their solutions are, or will


<PAGE>   16

be, Year 2000 compliant in all material respects. Failure of third-party
equipment or software to operate properly with regard to the Year 2000 and
thereafter could require us to incur unanticipated expenses to remedy any
problems, which could have a material adverse effect on our business, results of
operations and financial condition.

        Internal Systems. We have not initiated an assessment of our
non-information technology systems, including our electrical, heating and
telephone systems. We do not expect any Year 2000 issues to arise with respect
to these systems, however, if such issues arise, we do not expect that they
would have a material adverse effect on our business.

        Costs. To date, our costs to address Year 2000 compliance have not been
significant. We believe that the total cost of our Year 2000 compliance efforts
will not be material to our business. However, significant uncertainty exists
concerning the potential costs and effects associated with Year 2000 compliance.
If we encounter unexpected problems with respect to the Year 2000 issue, we
could incur additional costs, including significant cash outlays, which could be
material.

        Year 2000 Risks. Despite our investigations of the Year 2000 issue, we
have not received certifications from all of our third party suppliers and
vendors and it is possible that those certifications as well as the other
representations we have obtained could be erroneous.

        The purchasing patterns of our advertisers may be affected by Year 2000
issues as companies expend significant resources to correct their current
systems for Year 2000 compliance. These expenditures may result in reduced funds
available for Web advertising, which could have a material adverse effect on our
business, results or operations and financial condition.

        Failures of our systems to operate properly with regard to the Year 2000
could result in our Web sites being unavailable and our products and services
not functioning properly. Unavailability of our Web sites due to a lack of Year
2000 compliance could have a material adverse impact on our revenues and
operating expenses.

        In addition, the Internet is a network of computer systems which depends
on the functioning of a number of parts such as communications connections,
Internet service providers and power supplies, all of which are beyond our
control. The failure of these companies to be Year 2000 compliant could result
in a variety of systems failures such as electrical outages, Internet outages or
slower response times or telecommunications failures. These events could prevent
users from accessing our products and services or prevent us from updating or
delivering our products and services for a period of time or from selling
advertising on our web site for a period of time.

        Any of these events could have a material adverse effect on our
business, operating results and financial condition.

        Contingency Plans. We have not yet developed a formal contingency plan
for handling Year 2000 problems that are not detected and corrected prior to
their occurrence. Any failure to address any Year 2000 issue could adversely
affect our business, financial condition and results of operations.

        DBC has advised us that it has developed certain contingency options in
the event of a failure due to Year 2000 issues For example, if one data provider
fails, it is possible that there is another data provider that provides
substantially similar information that could be integrated into DBC s data feed.
There are certainly no foolproof contingency plans that cover every possible
failure. However, DBC will continue to develop potential solutions so that it is
as prepared as possible in the event of a failure. If we are unable to utilize
DoubleClick as a result of Year 2000 issues, we believe we could either seek to
obtain another vendor or deliver advertising using our own systems as we did in
the past. However, we may not be able to replace DoubleClick with another vendor
on reasonable terms, or if we delivered advertising ourselves, we may not be
able to track or measure the advertising to the same extent as DoubleClick.

RISK FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

RELIANCE ON OUR RELATIONSHIPS WITH CBS AND DBC

CBS

        We would need to change the name of our Web site and devote substantial
resources towards building a new brand name if our agreement with CBS were
terminated or not renewed. This agreement also has a number of risks associated
with it. CBS can require us to remove any content on our Web site that it
determines conflicts with, interferes with or is detrimental to its reputation
or business or for certain other reasons. We are also required to conform to
CBS's guidelines for the use of its trademarks. CBS has the right to approve all
materials, such as marketing materials, that include any CBS trademarks. CBS
also has control over the visual and editorial presentation of its television
news content on our Web site. Because of these restrictions, we may not be able
to perform our desired marketing activities.



<PAGE>   17

        Our license agreement with CBS will expire on October 29, 2005, and CBS
will have no obligation to renew it. CBS will also have the right to terminate
this agreement if:

        - we breach a material term or condition of the agreement;

        - we become insolvent or subject to bankruptcy or similar proceedings;

        - a competitor of CBS acquires 15% or more of our voting power;

        - we issue voting securities to, or actively participate in the
        acquisition of our voting power by a CBS competitor that results in such
        competitor directly or indirectly owning 9% or more of our voting power;
        or

        - we discontinue using the MarketWatch trademark and do not establish a
        substitute mark acceptable to CBS.

If our agreement with CBS is terminated prior to the end of its term, our
business could be adversely affected. Also, we have no formal agreement with CBS
with respect to any of our correspondents who provide reports to CBS or any of
its affiliates. Therefore, there can be no assurance that these services will
continue in the future.

        CBS has agreed, subject to certain limitations, to provide us an
aggregate rate card amount of $30.0 million of advertising and on-air promotions
during the period from October 29, 1997 through October 29, 2002 and we have
recognized $16.6 million of this rate card amount through September 30, 1999.
However, the timing and placement of these advertisements and promotions are
subject to CBS's discretion. CBS could discontinue promoting us in the manner
that it currently does. CBS also makes no guarantees to us as to the demographic
composition or size of the audience that views these advertisements or
promotions. This advertising and on-air promotion, as well as our association
with the CBS brand, are important elements of our strategy to increase our brand
awareness. This obligation will terminate if our license agreement terminates.

        We may not be able to continue to attract a sufficient amount of user
traffic and advertisers to our Web site without the CBS name and logo or
promotion from CBS.

DBC

        Data and hosting. DBC currently provides delayed financial data to us at
no charge. It also provides real-time financial data to us for dissemination to
subscribers of certain of MarketWatch.com subscription services in exchange for
a percentage of the subscription fee.

        General Services. DBC provides us with certain general services,
including accounting services and human resources services. We reimburse DBC for
its actual costs of providing these services.

        Payments for News. Under the Amended and Restated Services Agreement,
DBC pays us through October 2002 a monthly per-subscriber fee for delivery of
our news to all DBC subscribers, other than certain commercial ones, with a
minimum payment of $100,000 per month.

        Non-Competition Provisions. Through October 29, 2005, DBC will not be
able to:

        - sell advertising on a Web site that primarily delivers financial news
        and comprehensive stock quotes; or

        - use the Internet to sell, or authorize another to sell, real-time snap
        quotes to individual subscribers.

        Although the Stockholders' Agreement contains certain non-competition
provisions, these provisions have certain exceptions and do not provide for an
exclusive relationship.


<PAGE>   18

        If DBC fails to provide these services satisfactorily, we would be
required to perform these services ourselves or obtain these services from
another provider. Replacing these services could cause us to incur additional
costs. We may not be able to replace these services on commercially reasonable
terms or if we choose to perform these services ourselves, we may not be able to
perform them adequately. During any such transition, our services could be
disrupted for an indefinite period of time and, as a result, we could lose a
substantial number of users and advertisers.

CONTROL BY CBS AND DBC

        As of September 30, 1999, CBS and DBC each owned approximately 33% of
our outstanding common stock. CBS and DBC have certain rights to have
representatives on our board of directors generally based upon the percentage of
our voting securities that they hold. Currently, they each have three
representatives. As a result of their share ownership and other rights, CBS and
DBC collectively are able to control our management and affairs, elect a
majority of our Board of Directors and approve significant corporate
transactions. This concentration of ownership and other rights could also delay
or prevent a change in control.

If a competitor of CBS directly or indirectly acquires more than 30% of the
voting power of DBC or substantially all of DBC's assets at a time when DBC
beneficially owns at least 10% of our outstanding common stock, CBS may within
45 days either:

        - purchase all of our securities held by DBC; or

        - require DBC to place these securities in a trust that would then
        dispose of the securities with a view to maximizing the sale price while
        disposing of such shares as promptly as reasonably practicable.

        DBC would forfeit its Board representation in either event. We cannot
predict which option, if any, CBS would elect in such an event.

POTENTIAL FLUCTUATIONS IN OUR QUARTERLY OPERATING RESULTS; UNPREDICTABILITY OF
FUTURE REVENUE; EXPECTED FUTURE LOSSES; SEASONALITY

        Our quarterly operating results may fluctuate significantly in the
future as a result of a variety of factors, many of which are outside our
control. These factors include:

        - the early stage of our development, particularly given that we did not
        become a separate legal entity until October 1997 and we only became a
        public company in January 1999;

        - the level of Web usage;

        - traffic levels on our Web site, which can fluctuate significantly as a
        result of business and financial news events;

        - the demand for advertising on our Web site as well as on the Web in
        general;

        - changes in rates paid for Web advertising resulting from competition
        or other factors;

        - our ability to enter into or renew key agreements;

        - the amount and timing of our costs related to our marketing efforts or
        other initiatives including the amortization of promotion and
        advertising contributed by CBS;

        - demand for BigCharts content;

        - fees we may pay for distribution or content agreements or other costs
        we incur as we expand our operations;

        - new services introduced by us or our competitors;


<PAGE>   19

        - competitive factors;

        - technical difficulties or system downtime affecting the Web generally
        or the operation of our Websites; or

        - economic conditions specific to the Web as well as general economic
        conditions.

        Therefore, our operating results for any particular quarter may not be
indicative of future operating results.

        We expect that over time our revenues will come from a mix of
advertising, content licensing, e-commerce relationships and subscription
service fees. However, we expect to be substantially dependent on advertising
revenues and, to a lesser extent, content licensing revenues, for the
foreseeable future. Therefore, our quarterly revenues and operating results are
likely to be particularly affected by the level of our advertising revenue in
each quarter. Our operating expenses are based on our expectations of our future
revenues and are relatively fixed in the short term. If we have lower revenues,
particularly advertising revenues, than we expect, we may not be able to quickly
reduce our spending in response. Our cost structure could also change
dramatically as we increasingly operate independently from DBC. If we continue
to rely on DBC for administrative, hosting and other services we will be
required to reimburse DBC for its costs in providing the services. We will have
little control over the amount of these costs, which could be substantial. In
addition, we intend to significantly increase our operating expenses to grow our
business. Any shortfall in our revenues would have a direct impact on our
operating results for a particular quarter and these fluctuations could affect
the market price of our Common Stock in a manner unrelated to our long-term
operating performance.

        We have incurred operating losses in each fiscal quarter since we were
formed. We expect operating losses and negative cash flows to continue for the
foreseeable future as we intend to significantly increase our operating expenses
to grow our business.

        We believe that advertising sales in traditional media, such as
television and radio, generally are lower in the first and third calendar
quarters of each year. If our market makes the transition from an emerging to a
more developed medium, seasonal and cyclical patterns in our industry may
develop in the future. Therefore, if our industry follows the same seasonal
patterns as those in the traditional media, we may experience lower advertising
revenues in the first and third calendar quarters of each year. Furthermore,
traffic levels on our Web site typically fluctuate with the occurrence of
significant events in the business and financial news, such as fluctuations in
the stock markets that could cause changes in our audience size.

RISKS RELATED TO RECENT BIGCHARTS ACQUISITION

        Our acquisition of BigCharts closed on June 9, 1999, and involves a
number of risks. These include (i) risks to the merger, such as, risks involved
in assimilating BigCharts, risks involved in integrating, retaining and
motivating key BigCharts personnel, risks related to integrating and managing
geographically-dispersed operations because BigCharts is located in Minnesota
and MarketWatch.com is located in San Francisco, risks related to integrating
the technologies and infrastructures of the companies, and risks related to the
acceptance by BigCharts' brokerage customers of the merger; (ii) risks inherent
in BigCharts' business, such as its dependence on short-term customer contracts,
its dependence on a small number of customers for a significant portion of its
revenues, its business model which depends on selling its services directly to
customers as well as depending on the sale of advertising on the Web, its
dependence on maintaining relationships with key customers, and the extremely
limited operating history of BigCharts on which to base any revenue projections;
(iii) risks to MarketWatch.com of the increased negative cash flow and increased
operating expenses arising out of the merger; and (iv) the risk that BigCharts
customers and distribution partners will not utilize any additional services of
the combined company.

        The integration of operations, technology and personnel of
MarketWatch.com and BigCharts has been and will continue to be a complex, time
consuming and expensive process and may disrupt MarketWatch's business if not
completed in a timely and efficient manner. MarketWatch.com must operate as a
combined organization utilizing common information and communications systems,
operating procedures, financial controls and human resources practices.
MarketWatch.com and BigCharts may encounter substantial difficulties, costs and
delays involved in integrating their operations, including:

        - potential incompatibility of business cultures;

        - perceived adverse changes in business focus;

        - potential conflicts in sponsor, advertising or content relationships;
        and

        - the loss of key employees and diversion of the attention of management
        from other ongoing business concerns.


<PAGE>   20

The present and potential relationships of MarketWatch.com and BigCharts with
sponsors, content providers, advertisers, users and subscribers may be harmed by
the merger. Uncertainties regarding sponsorships and new service development
following the merger may cause these parties to delay decisions regarding these
relationships. Any changes in these relationships could harm MarketWatch.com's
business.

WE MUST DEVELOP AND IMPLEMENT OUR OWN INTERNAL SYSTEMS TO MANAGE OUR BUSINESS
AND OUR GROWTH

        Although our predecessor business has been operating since October 1995,
we did not become a separate legal entity until October 1997 when we were formed
as a limited liability company and we introduced our CBS.MarketWatch.com Web
site.

        We have been and continue to be substantially dependent on DBC for many
of our financial, administrative and operational services and related support
functions. We may not be able to perform these financial, administrative,
operational and support functions effectively as an independent company. In
addition, we believe that we will need further improvements in these systems,
controls and procedures to manage our growth. Our future financial performance
could be adversely affected if DBC or we do not perform these functions
effectively or if we do not implement these systems, controls and procedures
successfully.

WE WILL NEED TO ESTABLISH AND MAINTAIN STRATEGIC RELATIONSHIPS WITH OTHER WEB
SITES TO ATTRACT USERS, ADVERTISERS, AND CONTENT

        We depend on establishing and maintaining distribution relationships
with high-traffic Web sites for a significant portion of our traffic. For
example, for the month of September 1999, approximately 11% of our traffic came
from Yahoo!. There is intense competition for placements on these sites, and to
be able to enter into these types of relationships on commercially reasonable
terms or at all. Even if we enter into distribution relationships with these Web
sites, they may not attract significant numbers of users. Therefore, our site
may not receive additional users from these relationships. Moreover, we may have
to pay significant fees to establish and maintain these relationships.

        Occasionally we enter into agreements with advertisers, content
providers or other high traffic Web sites that require us to exclusively feature
these parties in certain sections of our Web site. Existing and future
exclusivity arrangements may prevent us from entering into other content
agreements, advertising or sponsorship arrangements or other strategic
relationships. Many companies we may pursue for a strategic relationship also
offer competing services. As a result, these competitors may be reluctant to
enter into strategic relationships with us. Our business could be adversely
affected if we do not establish and maintain additional strategic relationships
on commercially reasonable terms or if any of our strategic relationships do not
result in increased use of our Web site.

WE DEPEND ON A THIRD PARTY TO TRACK AND MEASURE THE DELIVERY OF ADVERTISEMENTS
FOR US AND IT COULD BE DIFFICULT TO REPLACE THESE SERVICES

        It is important to our advertisers that we accurately measure the
delivery of advertisements on our web site. We depend on third parties to
provide this measurement service. If they were unable to provide this service in
the future, we would be required to perform it ourselves or obtain it from
another provider. This could cause us to incur additional costs or cause
interruptions in our business during the time we are replacing this service. We
are implementing additional systems designed to record behavioral patterns of
our users. If we do not develop these systems successfully, we may not be able
to accurately evaluate the behavioral patterns of our users. Companies may not
advertise on our web site or may pay less for advertising if they do not
perceive our measurements or measurements made by third parties to be reliable.

WE DEPEND ON OUR DIRECT SALES FORCE TO SELL ADVERTISING ON OUR WEB SITE

        Until early 1998, we relied upon third parties to sell advertisements on
our web site. Since that time, we created our own internal sales force. As of
September 30, 1999, our sales group had 33 members. We depend on our sales force
to sell advertising on our web sites. This involves a number of risks:

        - many of our sales personnel have only worked for us for a short period
        of time;

        - our need to further increase the size of our sales force;

        - our ability to hire, retain, integrate and motivate additional sales
        and sales support personnel;


<PAGE>   21

        - the length of time it takes new sales personnel to become productive;
        and

        - the competition we face from other companies in hiring and retaining
        sales personnel.

        Our business would be adversely affected if we do not develop and
maintain an effective sales force.

WE NEED TO EXPAND OUR BUSINESS AND BE ABLE TO DO SO SUCCESSFULLY

        We believe that we will need to expand our business and operations both
to operate as an entity independent from DBC and in order to grow our business.
This growth, together with our expanded operations resulting from our
acquisition of BigCharts is likely to continue to place a significant strain on
our resources. As we grow, we will also have to implement new operational and
financial systems, procedures and controls. If we are unable to accomplish any
of these, our business could be adversely affected.

IF WE DO NOT DEVELOP NEW AND ENHANCED SERVICES AND FEATURES FOR OUR WEB SITES,
WE MAY NOT BE ABLE TO ATTRACT AND RETAIN A SUFFICIENT NUMBER OF USERS

        We believe that our Web site will be more attractive to advertisers if
we develop a larger audience comprised of demographically favorable users.
Accordingly, we intend to introduce additional or enhanced services in the
future in order to retain our current users and attract new users. We may also
seek to acquire businesses, products or technologies. If we introduce a service
that is not favorably received our current users may not continue using our
service as frequently. New users could also choose a competitive service over
ours.

        We may also experience difficulties that could delay or prevent us from
introducing new services. Furthermore, these services may contain errors that
are discovered after the services are introduced. We may need to significantly
modify the design of these services on our Web site to correct these errors. Our
business could be adversely affected if we experience difficulties in
introducing new services or if these new services are not accepted by users.

WE DEPEND ON THE CONTINUED GROWTH IN THE USE OF THE WEB, PARTICULARLY FOR
FINANCIAL NEWS AND INFORMATION

        Our market is new and rapidly evolving. Our business would be adversely
affected if Web usage does not continue to grow. Web usage may be inhibited for
a number of reasons, such as:

        - inadequate network infrastructure;

        - security concerns;

        - inconsistent quality of service; and

        - unavailability of cost-effective, high-speed service.

        If Web usage grows, the Internet infrastructure may not be able to
support the demands placed on it by this growth or its performance and
reliability may decline. In addition, Web sites have experienced interruptions
in their service as a result of outages and other delays occurring throughout
the Internet network infrastructure. If these outages or delays frequently occur
in the future, Web usage, as well as usage of our Web site, could grow more
slowly or decline.

WE DEPEND ON THE SALE OF ADVERTISEMENTS ON OUR WEB SITES AND IF WEB ADVERTISING
DOES NOT BECOME ACCEPTED, OUR BUSINESS WOULD BE HARMED

        We expect to derive a substantial amount of our revenues from
advertising for the foreseeable future. No standards have been widely accepted
to measure the effectiveness of Web advertising. If such standards do not
develop, existing advertisers may not continue their current levels of Web
advertising. Furthermore, advertisers that have traditionally relied upon other
advertising media may be reluctant to advertise on the Web. Advertisers that
already have invested substantial resources in other advertising methods may be
reluctant to adopt a new strategy. Our business would be adversely affected if
the market for Web advertising fails to develop or develops more slowly than
expected.


<PAGE>   22

        Different pricing models are used to sell advertising on the Web. It is
difficult to predict which, if any, will emerge as the industry standard. This
makes it difficult to project our future advertising rates and revenues. For
example, advertising rates based on the number of "click throughs," or user
requests for additional information made by clicking on the advertisement,
instead of rates based solely on the number of impressions, or times an
advertisement is displayed, could adversely affect our revenues because
impression-based advertising comprises a substantial majority of our current
advertising revenues. Our advertising revenues could be adversely affected if we
are unable to adapt to new forms of Web advertising. Moreover, "filter" software
programs that limit or prevent advertising from being delivered to a Web user's
computer are available. Widespread adoption of this software could adversely
affect the commercial viability of Web advertising.

WEB SECURITY CONCERNS COULD HINDER INTERNET COMMERCE

        The need to securely transmit confidential information over the Internet
has been a significant barrier to electronic commerce and communications over
the Web. Any well-publicized compromise of security could deter more people from
using the Web or from using it to conduct transactions that involve transmitting
confidential information, such as stock trades or purchases of goods or
services. Because many of our advertisers seek to advertise on our Web sites to
encourage people to use the Web to purchase goods or services, our business
could be adversely affected.

        We may also incur significant costs to protect against the threat of
security breaches or to alleviate problems caused by such breaches.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        Interest rate sensitivity. The primary objective of our investment
activities is to preserve principal while at the same time maximizing the income
we receive from our investments without significantly increasing risk. Some of
the securities that we have invested in may be subject to market risk. This
means that a change in prevailing interest rates may cause the principal amount
of the investment to fluctuate. For example, if we hold a security that was
issued with a fixed interest rate at the then-prevailing rate and the prevailing
interest rate later rises, the principal amount of our investment will probably
decline. To minimize this risk, we maintain our portfolio of cash in money
market funds and short-term investments classified as "available for sale". In
general, money market funds and short-term investments are not subject to market
risk because the interest paid on such funds fluctuates with the prevailing
interest rate. As of September 30, 1999, all of our investments mature in less
than one year.

        Exchange rate sensitivity. We consider our exposure to foreign currency
exchange rate fluctuations to be minimal, as we do not have any sales
denominated in foreign currencies. We have not engaged in any hedging
transactions to date.

PART II -- OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

        The Company is not currently aware of any legal proceedings or claims
that the Company believes will have, individually or in the aggregate, a
material adverse effect on the Company's financial position or results of
operations.

ITEM 2. CHANGE IN SECURITIES AND USED PROCEEDS

        On January 14, 1999, the Company's Registration Statement on Form S-1
(File No. 333-65569) was declared effective by the Securities and Exchange
Commission which registration statement related to the Company's initial public
offering of common stock. The managing underwriters of this offering were BT
Alex Brown Incorporated and Donaldson Lufkin & Jenrette Securities Corporation,
who acted as Joint Book Running Managers, and Salomon Smith Barney Inc. and
First Albany Corporation. All of the 3,162,500 shares registered were sold by
the Company. All of the shares of common stock were sold at a public offering
price of $17.00 per share, for an aggregate offering price of $53,763,000. The
amount of offering expenses were $5,931,000, including underwriting discount of
$3,763,000 and other offering expenses of $2,168,000 for net proceeds to the
Company of $47,832,000. As of September 30, 1999, the net proceeds to the
Company have been applied as follows: (i) $4.6 million for repayment of
outstanding indebtedness to Data Broadcasting Corporation, an affiliate of the
Company, (ii) $5.4 million in temporary investments, (iii) $17.3 million for
working capital and (iv) $7.5 million relating to the purchase of BigCharts.

        On June 9, 1999, the Company acquired all of the issued and outstanding
capital stock of BigCharts, Inc. pursuant to a merger of a newly formed, wholly
owned subsidiary of the Company with and into BigCharts, in exchange for
1,589,138 shares of the Company's common stock. In addition, the Company assumed
options to purchase capital stock of BigCharts, which options are exercisable
for an aggregate of 585,824 shares of the Company's common stock. The issuance
of shares of the Company's common stock and the assumption of options were made
in reliance on Section 4(2) and/or Regulation D promulgated under the Securities
Act.
