                               PROSPECTUS SUMMARY
 
     You should read the following summary together with the more detailed
information and Financial Statements and notes thereto appearing elsewhere in
this Prospectus.
 
     This Prospectus contains forward-looking statements. The outcome of the
events described in these forward-looking statements is subject to risks and
actual results could differ materially. The sections entitled "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business" as well as those discussed elsewhere in this
Prospectus contain a discussion of some of the factors that could contribute to
these differences.
 
                                MARKETWATCH.COM
 
     OUR BUSINESS
 
     We are a leading Web-based provider of comprehensive, real-time business
news, financial programming and analytic tools. Our CBS.MarketWatch.com Web site
also offers several tiers of paid subscription products, personal finance
commentary and data, community features and other services designed to provide a
"one-stop-shop" for our audience's financial information needs. We carefully
design and regularly update our Web site to provide well-organized, relevant and
clear programming. Our staff of over 40 professional journalists, including
freelance journalists, creates in-depth, up-to-the-minute business and financial
commentary and analysis throughout the trading day and our correspondents often
appear on CBS Television and CBS Radio News. We have important strategic
relationships with our principal stockholders Data Broadcasting Corporation, or
DBC, and CBS Broadcasting Inc., or CBS. Our goal is to create the preeminent
brand for real-time business news and financial programming on the Web. We
believe our focus on original and authoritative content and our access to a
national media audience through our CBS relationship will help us achieve this
goal. In October 1998, our Web site attracted nearly 2.2 million visitors, who
generated more than 48 million page views, as compared with approximately
785,000 visitors, who generated approximately 40 million page views in March
1998. Our visitor information was based on information provided to us by
DoubleClick, Inc., the company which delivers ads on our Web site and measures
and tracks our users.
 
     OUR MARKET OPPORTUNITY
 
     The Web has rapidly become a significant global medium, allowing content
providers to deliver information and programming in a manner not possible in
traditional broadcast and print media. Demand for comprehensive business
information and financial programming and the volume of online securities
trading have increased significantly. Traditional print media such as newspapers
and magazines cannot offer real-time data and information, and broadcasters are
limited in the depth and availability of their content. Not bound by these
limitations, we are well-positioned to exploit the significant market
opportunity that exists for a real-time business news, financial programming and
analytic tools provider.

     OUR STRATEGY
 
     Our strategy to exploit our market opportunity includes the following:
 
        - Build traffic and audience loyalty;
 
        - Deliver original, authoritative and timely programming with high
          editorial value;
 
        - Leverage CBS's name recognition and resources;
 
        - Maximize the use of DBC's data and analytic tools;
 
        - Build and capitalize on the attractive demographics of our audience;
          and
 
        - Pursue additional revenue streams.
 
     OUR CUSTOMERS
 
     We believe our Web site draws users who represent an attractive demographic
group for companies that advertise and conduct business over the Internet. Since
introducing our CBS.MarketWatch.com Web site, we have successfully attracted
more than 100 advertisers across a broad range of industries, beginning with
advertisers in the financial services and technology industries and more
recently in the automotive, travel and consumer retailing industries.
 
     OUR HISTORY
 
     We were formed in October 1997 as a joint venture 50% owned by each of CBS
and DBC. CBS licensed its name, logo and certain news content for use in
connection with the CBS.MarketWatch.com Web site. When this joint venture was
formed, CBS and DBC agreed that their contributions would be treated as having
equal value. CBS initially licensed us the right to use its name, logo and news
content for a period of five years in exchange for a royalty of approximately
30% of our banner advertising revenue. It also separately agreed to provide us
with $50 million in rate card promotion and advertising. Immediately prior to
the closing of this offering, CBS agreed to amend the license to extend the term
through October 2005, to provide us with $30 million in rate card promotion and
advertising from October 1997 through October 2002 and to amend the royalty rate
to be paid by us from 30% of banner advertising revenues to 6 to 8% of gross
revenues, subject to certain limitations. DBC contributed certain assets related
to our predecessor business, which it formed in October 1995, and agreed to
provide our initial funding. Under a services agreement, DBC agreed to provide
ongoing services, including hosting our Web site through October 2002.
Immediately prior to the closing of this offering, this services agreement was
amended to provide for an eight-year term through October 2005 and to add other
provisions relating to system performance and hardware. Our address is 825
Battery Street, San Francisco, California, 94111 and our telephone number is
(415) 733-0500.

                                  RISK FACTORS
 
     This offering involves a high degree of risk. You should carefully consider
the risks described below and the other information in this Prospectus before
deciding to invest in shares of our Common Stock.
 
RISKS RELATED TO OUR RELATIONSHIP WITH CBS AND DBC
 
  CONTROL BY CBS AND DBC
 
     After this offering, CBS and DBC each will own approximately 38% of our
outstanding Common Stock. CBS and DBC will have certain rights to have
representatives on our Board of Directors generally based upon the percentage of
our voting securities which they hold. Initially, they will each have three
representatives. If we issue voting securities, or securities convertible into
or exchangeable for voting securities in the future, subject to certain
limitations, CBS and DBC will each have the right to purchase securities from us
so they can maintain their respective percentage ownerships. In addition, if
either CBS or DBC desires to transfer any shares of Common Stock held by it, the
other party has a right of first refusal to purchase all or a portion of those
shares, subject to certain exceptions. As a result of their share ownership and
the other rights described in this Prospectus, CBS and DBC collectively will be
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. See
"Certain Transactions," "Principal Stockholders" and "Description of Capital
Stock."
 
     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 which 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. Although DBC has
advised us that it has no present plans or intentions to effect such a
transaction, DBC could effect such a transaction at any time in the future. See
"Description of Capital Stock -- Rights of First Refusal."
 
  DEPENDENCE ON CBS RELATIONSHIP
 
     We license the CBS logo, name and certain news content from CBS. The CBS
logo and name are critical to our marketing and brand building activities. 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 which 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.
 
     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;
 
                                        6
<PAGE>   7
 
     - 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 which 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.
 
     CBS has agreed, subject to certain limitations, to provide us an aggregate
rate card amount of $30 million of advertising and on-air promotions during the
period from October 29, 1997 through October 29, 2002. 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. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations," "Business -- Strategic Relationships,"
"Certain Transactions" and Note 7 of Notes to MarketWatch.com Financial
Statements.
 
  DEPENDENCE ON DBC RELATIONSHIP
 
     DBC has provided us with substantially all of our cash funding to date and
has accounted for a substantial portion of our revenues. DBC also currently
provides us with Web site hosting services, software programming assistance,
data feeds, communications lines, and related facilities, network operations and
Web site management services as well as certain administrative, engineering and
human resources services. 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 ourself, 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. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations," "Certain
Transactions" and Note 7 of Notes to MarketWatch.com Financial Statements.
 
  POTENTIAL COMPETITION FROM CBS AND DBC
 
     Although our agreements with CBS and DBC contain certain limited
non-competition provisions, these provisions have certain exceptions and are not
exclusive relationships. For example:
 
     - CBS could license its name and logo to other Web sites or Internet
       services that deliver general news, sports or entertainment. These sites
       or services could also offer financial news, so long as delivering
       comprehensive stock quotes and financial news to consumers in the English
       language is not their primary function and their principal theme and
       format;
 
     - DBC may provide hosting services to other Web sites;
 
     - DBC could also establish an advertising-supported Web site that does not
       have as its primary function and its principal theme and format the
       delivery of financial news and stock quotes;
 
     - CBS or DBC could license its content to other Web sites or Internet
       services; or
 
     - CBS or DBC could make certain investments in other Web sites or Internet
       services.
                                        7
<PAGE>   8
 
     Any of these could adversely affect us. For example, these sites or
services could compete with us or CBS and DBC might promote these other sites or
services more actively than they promote our Web site. See
"Business -- Strategic Relationships" and "Certain Transactions."
 
RISKS RELATED TO OUR BUSINESS
 
  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;
 
     - 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 such as our recent
       agreement with Yahoo!;
 
     - the amount and timing of our costs related to our marketing efforts or
       other initiatives;
 
     - 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;
 
     - competitive factors;
 
     - technical difficulties or system downtime affecting the Web generally or
       the operation of our Web site; 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 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 the services described under "-- Dependence on DBC
Relationship," 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.
 
                                        8

     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. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
  NEED TO DEVELOP AND IMPLEMENT OUR OWN INTERNAL SYSTEMS
 
     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 to host our
Web site and 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 we or DBC do not perform these
functions effectively or if we do not implement these systems, controls and
procedures successfully.
 
  INTENSE COMPETITION FOR WEB-BASED BUSINESS AND FINANCIAL CONTENT
 
     Many Web sites compete for consumers' and advertisers' attention and
spending, particularly in the business and financial information and news area.
We expect this competition to continue to increase. We compete for advertisers,
users and content providers with many types of companies:
 
     - publishers and distributors of traditional media, including television,
       radio and print, such as The Wall Street Journal, CNN and CNBC;
 
     - general purpose consumer online services such as America Online and
       Microsoft Network;
 
     - online services or Web sites targeted to business, finance and investing
       needs, such as TheStreet.com and Motley Fool; and
 
     - Web retrieval and other Web "portal" companies, such as Excite, Inc.,
       Infoseek Corporation, Lycos, Inc., Yahoo! Inc., and Netscape
       Communications Corporation.
 
     Increased competition could result in price reductions, reduced margins or
loss of market share, any of which would adversely affect our business. See
"Business -- Industry Background" and "-- Competition."
 
  NEED TO ESTABLISH AND MAINTAIN STRATEGIC RELATIONSHIPS WITH OTHER WEB SITES
 
     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 November 1998, approximately 10% of our traffic came from
Yahoo!. There is intense competition for placements on these sites, and we may
not be able to enter into such relationships on commercially reasonable terms or
at all. Even if we enter into distribution relationships with these Web sites,
they themselves 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 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
 
                                        9
<PAGE>   10
 
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.
 
  RISKS RELATING TO OUR ABILITY TO TRACK AND MEASURE THE DELIVERY OF
ADVERTISEMENTS
 
     It is important to our advertisers that we accurately measure the
demographics of our user base and the delivery of advertisements on our Web
site. We depend on third parties to provide these measurement services. If they
are unable to provide these services in the future, we would be required to
perform them ourselves or obtain them from another provider. This could cause us
to incur additional costs or cause interruptions in our business during the time
we are replacing these services. We are implementing additional systems designed
to record demographic data on our users. If we do not develop these systems
successfully, we may not be able to accurately evaluate the demographic
characteristics 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.
 
  DEVELOPMENT OF OUR DIRECT SALES FORCE
 
     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. On
November 30, 1998, our sales group had 14 members. We depend on our sales force
to sell advertising on our Web site. This involves a number of risks:
 
     - 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;
 
     - 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.
 
  DEPENDENCE ON FINANCIAL INDUSTRY ADVERTISERS
 
     Financial services companies have accounted for the substantial majority of
our advertising revenues. We will need to sell advertising to customers outside
of the financial services industry in order to increase our revenues. To date,
relatively few advertisers from industries other than the technology and
financial services industries have devoted a significant portion of their
advertising budgets to Web advertising. If we do not attract advertisers from
other industries, our business could be adversely affected.
 
  RISKS OF INCREASED USERS STRAINING OUR SYSTEMS AND OTHER SYSTEM MALFUNCTIONS
 
     In the past, our Web site has experienced significant increases in traffic
when there are significant business or financial news stories. In addition, the
number of our users has continued to increase over time and we are seeking to
further increase our user base. Therefore, our Web site must accommodate a high
volume of traffic and deliver frequently updated information. Our Web site has
in the past and may in the future experience slower response times or other
problems for a variety of reasons.
 
     We also depend on information providers, including DBC, to provide
information and data feeds on a timely basis. Our Web site could experience
disruptions or interruptions in service due to
 
                                       10
<PAGE>   11
 
the failure or delay in the transmission or receipt of this information. In
addition, our users depend on Internet service providers, online service
providers and other Web site operators for access to our Web site. Each of them
has experienced significant outages in the past, and could experience outages,
delays and other difficulties due to system failures unrelated to our systems.
These types of occurrences could cause users to perceive our Web site as not
functioning properly and therefore cause them to use other methods to obtain
their business and financial news and other information.
 
  NEED TO EXPAND OUR BUSINESS AND RELATED PROBLEMS
 
     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 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. In addition, several members
of our senior management joined us in 1998, including our Vice Presidents of
Advertising Sales and of Marketing and our Chief Financial Officer. As a result,
our senior managers may not work together effectively as a team to successfully
manage our growth.
 
  RISKS OF DEVELOPING NEW AND ENHANCED SERVICES AND FEATURES FOR OUR WEB SITE
 
     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. 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.
 
RISKS RELATED TO OUR INDUSTRY
 
  DEPENDENCE ON CONTINUED GROWTH IN USE OF THE WEB
 
     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
 
     - availability 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.
 
  RISKS ASSOCIATED WITH OUR BUSINESS MODEL WHICH DEPENDS ON WEB ADVERTISING
 
     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
 
                                       11
<PAGE>   12
 
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. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business -- Strategy" and "-- Advertising and Sales."
 
     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.
 
  GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES RELATING TO THE WEB
 
     There are currently few laws or regulations that specifically regulate
communications or commerce on the Web. However, laws and regulations may be
adopted in the future that address issues such as user privacy, pricing, and the
characteristics and quality of products and services. For example, the
Telecommunications Act sought to prohibit transmitting certain types of
information and content over the Web. Several telecommunications companies have
petitioned the Federal Communications Commission to regulate Internet Service
Providers and online services providers in a manner similar to long distance
telephone carriers and to impose access fees on these companies. This could
increase the cost of transmitting data over the Internet. Moreover, it may take
years to determine the extent to which existing laws relating to issues such as
property ownership, libel and personal privacy are applicable to the Web. Any
new laws or regulations relating to the Web could adversely affect our business.
 
  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 site 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.
 
  STORAGE OF PERSONAL INFORMATION ABOUT OUR USERS
 
     We have a non-disclosure policy displayed on our Web site. Our policy is
not to willfully disclose any individually identifiable information about any
user to a third party without the user's consent. This policy is accessible to
users of our personalized services when they initially register. Despite this
policy, however, if third persons were able to penetrate our network security or
otherwise misappropriate our users' personal information or credit card
information, we could be subject to liability. These could include claims for
unauthorized purchases with credit card information, impersonation or other
similar fraud claims. They could also include claims for other misuses of
personal information, such as for unauthorized marketing purposes. These claims
could result in litigation. In addition, the Federal Trade Commission and other
states have been investigating certain Internet companies regarding their use of
personal information. We could incur additional expenses if new regulations
regarding the use of personal information are introduced or if they chose to
investigate our privacy practices.
 
                                       12
<PAGE>   13
 
  LIABILITY FOR INFORMATION DISPLAYED ON OUR WEB SITE
 
     We may be subjected to claims for defamation, negligence, copyright or
trademark infringement or based on other theories relating to the information we
publish on our Web site. These types of claims have been brought, sometimes
successfully, against online services as well as other print publications in the
past. We could also be subjected to claims based upon the content that is
accessible from our Web site through links to other Web sites. Our insurance may
not adequately protect us against these types of claims.
 
RISKS RELATED TO THIS OFFERING
 
  ANTI-TAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW
 
     Certain provisions of our Amended and Restated Certificate of
Incorporation, Bylaws, other agreements and Delaware law could make it more
difficult for a third party to acquire us, even if a change in control would be
beneficial to our stockholders. See "Risks Related to Our Relationship with CBS
and DBC -- Control by CBS and DBC," "Certain Transactions" and "Description of
Capital Stock."
 
  SHARES ELIGIBLE FOR PUBLIC SALE AFTER THIS OFFERING COULD ADVERSELY AFFECT OUR
STOCK PRICE
 
     After this offering there will be outstanding 11,750,000 shares of our
Common Stock. There will be 12,162,500 shares outstanding if the Underwriters'
over-allotment option is exercised in full. Of these shares, the shares sold in
this offering will be freely tradeable except for any shares purchased by our
"affiliates" as defined in Rule 144 under the Securities Act. The remaining
9,000,000 shares held by CBS and DBC will be "restricted securities" and will
become eligible for sale no later than the first anniversary of the date our
business is changed to a corporation, subject to the volume limitations and
other conditions of Rule 144 under the Securities Act. In addition, 180 days
after this offering, at least 233,237 shares will be issuable upon the exercise
of options (based on options outstanding on November 30, 1998). Sales of a large
number of shares could have an adverse effect on the market price for our Common
Stock.
 
     Neither CBS nor DBC has any restrictions on selling any of our securities
held by it, other than as provided in lock-up agreements with BT Alex. Brown
Incorporated and Donaldson, Lufkin & Jenrette Securities Corporation, the
Stockholders' Agreement and under applicable securities laws. In addition, CBS
and DBC can require us to register our securities they own for public sale. Any
sales by these stockholders could adversely affect the trading price of our
Common Stock. See "Management -- Director Compensation," "-- Employee Benefit
Plans," "Description of Capital Stock -- Registration Rights" and "Shares
Eligible for Future Sale."
 
  POSSIBLE VOLATILITY OF OUR STOCK PRICE
 
     We cannot predict the extent to which investor interest in MarketWatch.com
will lead to the development of a trading market or how liquid that market might
become. The initial public offering price for the shares was determined by
negotiations between MarketWatch.com and the representatives of the Underwriters
and may not be indicative of prices that will prevail in the trading market. The
stock market has experienced significant price and volume fluctuations and the
market prices of securities of technology companies, particularly
Internet-related companies, have been highly volatile. Investors may not be able
to resell their shares at or above the initial public offering price. See
"Underwriting."
 
     In the past, following periods of volatility in the market price of a
company's securities, securities class action litigation has often been
instituted against such a company. Such litigation could result in substantial
costs and a diversion of management's attention and resources.

<PAGE>   14
 
                                USE OF PROCEEDS
 
     We estimate that the net proceeds from the sale of the 2,750,000 shares of
Common Stock offered hereby will be approximately $42.1 million, after deducting
the underwriting discounts and commissions and estimated offering expenses. If
the Underwriters' over-allotment option is exercised in full, we estimate that
such net proceeds will be approximately $48.6 million. The principal purposes of
this offering are to obtain additional capital, create a public market for our
Common Stock and facilitate our future access to the public capital markets.
 
     We intend to use at least $5.0 million of the net proceeds of this offering
for marketing activities during 1999 and a portion of the net proceeds to repay
all outstanding indebtedness to DBC ($3.0 million at September 30, 1998). This
indebtedness matures on October 29, 2000 and bears interest at a rate equal to
the prime rate of The Chase Manhattan National Bank plus 2% (10.25% at September
30, 1998). We expect to use the remainder of the net proceeds for general
corporate purposes, including working capital such as expansion of sales and
marketing activities and the acquisition of content and distribution
relationships. The amounts actually expended for such working capital purposes
may vary significantly and will depend on a number of factors, including the
amount of our future revenues and the other factors described under "Risk
Factors." Accordingly, we will retain broad discretion in the allocation of the
net proceeds of this offering. A portion of the net proceeds may also be used to
acquire or invest in complementary businesses, technologies, product lines or
products. We have no current plans, agreements or commitments with respect to
any such acquisition, and we are not currently engaged in any negotiations with
respect to any such transaction. Pending such uses, the net proceeds of this
offering will be invested in short-term, interest-bearing, investment grade
securities.
 
                                DIVIDEND POLICY
 
     We have never declared or paid any cash dividends on our capital stock and
do not anticipate paying any cash dividends on our capital stock in the
foreseeable future. We may incur indebtedness in the future which may prohibit
or effectively restrict the payment of dividends, although we have no current
plans to do so.

sale of the 2,750,000 shares of Common Stock offered hereby, after deducting
underwriting discounts and commissions and estimated offering expenses, the pro
forma net tangible book value of MarketWatch.com as of September 30, 1998 would
have been $40.0 million, or $3.41 per share. This represents an immediate
increase in pro forma net tangible book value of $3.64 per share to existing
stockholders and an immediate dilution of $13.59 per share to new investors. The
following table illustrates this per share dilution:

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. MarketWatch.com, a joint venture owned 50% each by DBC and
CBS, was formed as a limited liability company in October 1997. It was 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 this offering, we were re-organized from an LLC into a corporation.
 
     The DBC Online/News Business developed the dbc.com Web site to deliver
financial quotes and news to users free of charge. While operating as DBC
Online/News, DBC sold advertising banners and sponsorships and subscriptions to
MarketWatch RT. With the formation of the LLC, the dbc.com site was changed to
the CBS.MarketWatch.com site. Since the formation of the LLC, MarketWatch.com
has operated as a provider of business news, financial programming and analytic
tools, with services including new 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 and
subscriptions to MarketWatch RT. We have also begun selling news to DBC and
subscriptions to MarketWatch Live.
 
     DBC's principal products are Signal, StockEdge, BMI, InSite, BondEdge and
QuoTrek, which provide real-time streaming quotes and financial market data to
subscribers using the Internet, cable television, FM radio, satellite and direct
telephone lines. DBC developed DBC Online/News with the original intent of
enhancing its existing services to its subscribers. Subsequently DBC began to
sell advertising on the dbc.com Web site. While MarketWatch.com's principal
source of revenue is advertising, DBC's principal source of revenue is
subscriptions. 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. See
"Risk Factors -- Risks Related to Our Relationship with CBS and DBC -- Potential
Competition from CBS and DBC."
 
     We have yet to achieve significant revenue and our ability to generate
significant revenue 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
 
                                       18

business. 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.
 
AGREEMENTS WITH CBS AND DBC
 
     Upon formation of the LLC, DBC agreed to contribute $2.0 million in cash
and the intellectual property of the DBC Online/News Business for its 50%
ownership interest. DBC simultaneously entered into a five-year Services
Agreement to provide us with our Web site infrastructure and certain operational
and administrative services at DBC's cost. Under this original Services
Agreement, DBC also agreed to pay us between $2.50 and $5.00 per month for each
DBC subscriber who receives real-time streaming quotes, subject to a minimum of
$100,000 per month. We refer to these payments as the Subscriber Payments. CBS
agreed to contribute $50 million in rate card advertising and promotion over
five years for its 50% ownership interest. CBS simultaneously entered into a
five-year License Agreement to license its CBS "Eye" design and certain CBS news
content, in exchange for royalties approximating 30% of our advertising banner
revenue.
 
     Immediately prior to the closing of this offering, the agreements will be
amended so that CBS will contribute $30 million in rate card advertising through
October 2002 instead of $50 million, the license will be extended for three
years to October 29, 2005, the royalties will be modified from 30% of
advertising revenue to approximately 8% of all revenue other than revenue
attributable to DBC and certain other revenue and DBC's service obligation will
be 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. See "Certain
Transactions -- Reorganization Transactions."
 
RESULTS OF OPERATIONS
 
     We have compared below the results of operations of MarketWatch.com and DBC
Online/News for the nine months ended September 30, 1998 and 1997 ("Nine Months
Results of Operations"). In addition, we have presented and compared as
supplemental information the results of operations of the sequential quarters
ended March 31, 1997 through September 30, 1998 ("Quarterly Results of
Operations"). We have also compared the results of operations for DBC
Online/News for the period from January 1, 1997 through October 28, 1997, the
year ended December 31, 1996, and the period from October 1, 1995 through
December 31, 1995 ("Results of Operations -- DBC Online/News Only").
 
     The results of operations for DBC Online/News reflect the carve-out
historical results of operations of the online and news businesses of DBC prior
to the formation of MarketWatch.com. These results of operations include all
revenue and costs directly attributable to the DBC Online/News Business,
including costs for facilities, functions and services used by the business at
shared sites and allocations of costs for certain administrative functions and
services performed by centralized departments within DBC. Costs have been
allocated based on DBC management's estimate of the costs that would have been
incurred if the DBC Online/News Business had been a separate entity.
 
     The following descriptions of the components of revenue and expenses apply
to the Nine Months Results of Operations, the Quarterly Results of Operations
and the Results of Operations -- DBC Online/News only:
 
     - Advertising revenues consist primarily of sales of advertising banners
       and sponsorships.
 
     - News to DBC revenues are the Subscriber Payments from DBC which represent
       fees from the sale to DBC by MarketWatch.com of its news for between
       $2.50 and $5.00 per month for each DBC subscriber who receives real-time
       streaming quotes, subject to a minimum of $100,000
 
                                       19
<PAGE>   20
 
       per month. Prior to the formation of the LLC, DBC Online/News did not
       charge DBC for this news. After this offering, we will only receive
       Subscriber Payments from DBC subscribers other than certain commercial
       subscribers.
 
     - Subscription revenues are from the sale of subscriptions to DBC's
       MarketWatch RT and MarketWatch Live products and not from the sale of any
       proprietary services of MarketWatch.
 
     - Cost of revenues for advertising and news includes compensation and
       benefits for news reporters and editors, royalties payable to CBS and
       content providers, Web site infrastructure costs allocated from DBC,
       exchange fees and beginning in 1998, the cost of serving ads by
       Doubleclick. Web infrastructure costs include communications lines,
       computer equipment, and DBC network operations personnel costs. All such
       cost incurred are necessary to support both news and advertising revenue
       streams. Allocation of costs between each revenue stream has not been
       made since all costs would continue to be incurred if we did not have
       either DBC news or advertising revenue.
 
     - Cost of revenues for subscriptions includes exchange fees, communication
       lines and royalties paid to DBC.
 
     - Product development expenses are primarily compensation and benefits for
       software developers and expenses for contract programmers and developers.
 
     - General and administrative expenses consist primarily of compensation and
       benefits for finance and administrative personnel, allocations from DBC
       for administrative services, occupancy costs, professional fees,
       depreciation and charges for bad debts.
 
     - Sales and marketing costs consist primarily of promotion and advertising
       provided by CBS beginning in 1998, Internet banner ads, advertising
       commissions, promotional materials and compensation, benefits and sales
       commissions to our direct sales force. Sales and marketing expenses prior
       to formation of MarketWatch.com were not significant.
 
     See Note 2 to the MarketWatch.com Financial Statements for a description of
how we recognize our net revenues.

</TABLE>
 
Net Revenues
 
     Net revenues for the nine months ended September 30, 1998 increased
compared to the nine months ended September 30, 1997 due to increases in the
number of banner and sponsorship ads placed on our web sites. The increases were
caused by several interrelated factors, including the following:
 
     - increased number of advertisers;
 
     - increased audience acceptance of our Web sites and resultant page views;
 
     - increased size of our direct sales force; and
 
     - increased flexibility and sophistication of advertising packages offered
       to advertisers.
 
                                       21
<PAGE>   22
 
     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
secure new advertising contracts from existing customers or obtain new
customers. We expect to continue to derive a substantial majority of net
revenues from selling advertisements. The market for Web advertising is
intensely competitive, advertising rates could be subject to pricing pressure in
the future. If are forced to reduce our advertising rates or we experience lower
CPMs across our Web site or click-through advertising rates as a result of such
competition or otherwise, future revenues could be adversely affected.
 
Cost of Revenues
 
     Cost of revenues for the nine months ended September 30, 1998 increased
compared to the nine months ended September 30, 1997 due to the addition of news
reporters and editors, additional network communications lines to accommodate
increased traffic on our sites, and fees payable to Doubleclick to serve ads.
Costs charged by DBC were $296,000 and $172,000 for the nine months ended
September 30, 1998 and 1997, respectively. Royalties to CBS were $148,000 and $0
for the nine months ended September 30, 1998 and 1997, respectively. As a
percent of net revenues, cost of revenues decreased by 20% because certain news
content and Web infrastructure expenses are relatively fixed.
 
Operating Expenses
 
     Since inception, operating expenses have increased significantly to reflect
the costs associated with the growth and development of MarketWatch.com and our
Web site. We continue to be substantially dependent on DBC for many of our
financial, administrative and operational services and related support
functions. This dependence involves a number of risks. See "Risk Factors --
Risks Related to Our Relationship with CBS and DBC -- Dependence on DBC
Relationship." We plan to implement independent financial, operational and
management controls, and reporting systems and procedures to support the
continued expansion of our operations. As a consequence, we intend to continue
to increase expenditures in all operating areas to support our planned growth
and the development of its infrastructure.
 
     Product Development. Product development expenses for the nine months ended
September 30, 1998 increased compared to the nine months ended September 30,
1997 due to increased headcount and expenses related to development of software
by third parties. As a percentage of net revenues, product development expenses
declined due to the much greater increase in revenues and the relatively small
amount of such expenses. We intend to increase the absolute dollar level of
product development expenditures in future periods in order to further enhance
the programming on the web site and these expenses may fluctuate as a percentage
of revenue over time depending on the projects undertaken by us from
time-to-time.
 
     We include in produce development expenses the amortization of deferred
compensation related to options granted below fair market value. Amortization of
deferred compensation was $38,000 for the nine months ended September 30, 1998.
 
     General and Administrative. General and administrative expenses for the
nine months ended September 30, 1998 increased compared to the nine months ended
September 30, 1997 due to increased headcount, occupancy and bad debts. Costs
charged by DBC were $216,000 and $104,000 for the nine months ended September
30, 1998 and 1997, respectively. We anticipate hiring additional personnel and
incurring additional costs related to being a public company, including
directors and officers liability insurance, investor relation programs and
professional service fees. Accordingly, we intend to increase the absolute
dollar level of general and administrative expenses in future periods.
 
                                       22
<PAGE>   23
 
     We include in general and administrative expenses the amortization of
deferred compensation related to options granted below fair market value.
Amortization of deferred compensation was $93,000 for the nine months ended
September 30, 1998.
 
     Sales and Marketing. Sales and marketing expenses for the nine months ended
September 30, 1998 increased compared to the nine months ended September 30,
1997 due to a number of factors including:
 
        - promotions and advertising contributed by CBS in 1998;
 
        - development of our direct sales force in 1998, and increased sales
          commissions from higher advertising sales;
 
        - increased Web banner ads to promote our products and services; and
 
        - purchase of traditional print and broadcast ads in 1998 to promote our
          products and services.
 
     We expect to increase our sales staff and significantly increase the
absolute dollar level of sales and marketing expenses in future periods.
 
     CBS has agreed to provide advertising and promotions over a five-year
period ending October 29, 2002. The Company will record an expense at the time
the advertising and promotion is provided based on the rate card value. The
Company has recorded advertising expense of $3.4 million at the rate card value
for the six months ended June 30, 1998 and $5.0 million at the rate card value
for the nine months ended September 30, 1998 (unaudited) related to services
provided by CBS. As of September 30, 1998, CBS has agreed to provide the
remaining $25.0 million rate card amount of advertising and promotions, assuming
execution of the Stockholders' Agreement prior to closing this offering. See
Note 8 to the MarketWatch.com Financial Statements.
 
  Interest Expense
 
     Interest expense for the nine month period ended September 30, 1998
compared to September 30, 1997 decreased to a comparatively lower advance
balance due to DBC over the nine month period ended September 30, 1998.

Net Revenues
 
     Net revenues have increased sequentially from quarter to quarter throughout
the periods presented due to increases in the number of banner and sponsorship
ads placed on our Web sites. After formation of MarketWatch.com in October 1997
and the decision to establish a direct sales force during the quarter ended
March 31, 1998, absolute dollar increases in net advertising revenues began to
increase at a substantially greater rate. We believe that the CBS brand has also
been a significant factor for accelerating advertising revenue.
 
Cost of Revenues
 
     Cost of revenues have increased sequentially from quarter to quarter
throughout the periods presented due to additions of new reporters and editors,
additional network communications lines to accommodate increased traffic on our
sites, and fees payable to Doubleclick to serve ads. As a percent of net
revenues, cost of revenues decreased steadily from the quarter ended March 31,
1997 to March 31, 1998, because certain news content and Web infrastructure
expenses are relatively fixed. In the quarter ended June 30, 1998, the costs
increased as a percent of net revenues due to significant hiring of reporters in
that quarter and a full quarterly impact of the cost of using DoubleClick to
serve ads.
 
Operating Expenses
 
     Product Development. Product development expenses have increased in
absolute dollars from the quarter ended March 31, 1997 to the quarter ended
September 30, 1998, particularly as a result of the hiring of Web site
development personnel in the second quarter of 1998. DBC Online/ News' product
development expenses reflect initial costs of developing the service and
bringing it online and the introduction of MarketWatch RT in December 1997. To
date, all product development costs have been expensed as incurred.
 
     General and Administrative. General and administrative expenses have
increased sequentially from quarter to quarter since the formation of
MarketWatch.com due to increased headcount, occupancy costs and infrastructure
costs charged by DBC. Our need for general and administrative functions and
infrastructure was relatively constant during the initial phases of the DBC
Online/ News Business, and therefore these costs remained constant during this
time.
 
     Sales and Marketing. Sales and marketing expenses have increased
sequentially from quarter to quarter since the formation of MarketWatch.com due
to promotions and advertising contributed by CBS in 1998, continued development
of our direct sales force beginning in January 1998, increased sales commissions
from higher advertising sales, increased spending on Web banner ads to promote
our Web site, and placement of traditional print and broadcast ads to promote
our Web site.
 
Interest Expense
 
     The increase in interest expense has fluctuated over the periods due to
changes in the amount of advances from DBC.
 
RESULTS OF OPERATIONS -- DBC ONLINE/NEWS BUSINESS
 
Net Revenues
 
     Net revenues were $1.2 million, $607,000 and $0 for the period from January
1, 1997 through October 28, 1997, the year ended December 31, 1996 and for the
period from inception (October 1, 1995) through December 31, 1995, respectively.
The year ended December 31, 1996 was the first period in which DBC made its Web
site and the MarketWatch RT online service publicly available. The increase in
revenue during these time periods is primarily attributable to an increase in
the number of customers advertising on the Web site.
 
                                       25

Cost of Revenues
 
     Cost of revenues were $660,000, $451,000 and $0 for the period from January
1, 1997 through October 28, 1997, the year ended December 31, 1996 and for the
period from inception through December 31, 1995, respectively. Cost of revenues,
as a percentage of net revenues, for the period from January 1, 1997 through
October 28, 1997, the year ended December 31, 1996 and for the period from
inception through December 31, 1995, respectively, were 56%, 74% and 0%. The
decrease in cost of revenues, as a percentage of net revenues in the latter two
periods, is primarily attributable to advertising revenues increasing while a
portion of the costs associated with providing the advertising remained
relatively constant. Included in cost of revenues are costs allocated from DBC.
Allocated expenses were $191,000, $160,000 and $0 for the period from January 1,
1997 through October 28, 1997, the year ended December 31, 1996 and for the
period from inception through December 31, 1995, respectively.
 
Operating Expenses
 
     Product Development. Product development expenses were $885,000, $1.2
million and $210,000 for the period from January 1, 1997 through October 28,
1997, the year ended December 31, 1996 and for the period from inception through
December 31, 1995, respectively. Product development, as a percentage of net
revenues, were 76%, 191% and 0% for the period from January 1, 1997 through
October 28, 1997, the year ended December 31, 1996 and for the period from
inception through December 31, 1995, respectively. The decrease in product
development expenses in absolute dollars from inception (October 1, 1995)
through December 31, 1995 and the year ended December 31, 1996 compared to the
ten month period ended October 28, 1997 is primarily due to high product
development costs incurred during the period from October 1995 through April
1996 in the development of the Web site and the MarketWatch RT online service.
 
     General and Administrative. General and administrative expenses were
$943,000, $732,000 and $26,000 for the period from January 1, 1997 through
October 28, 1997, the year ended December 31, 1996 and for the period from
inception through December 31, 1995, respectively. General and administrative
expenses, as a percentage of net revenues, were 80%, 121% and 0% for the period
from January 1, 1997 through October 28, 1997, the year ended December 31, 1996
and for the period from inception through December 31, 1995, respectively.
General and administrative expenses as a percentage of net revenues, decreased
from the year ended December 31, 1996 in the later two periods due to costs
associated with the implementation of billing systems related to MarketWatch RT
incurred during 1996. Included in general and administrative expenses are costs
allocated from DBC. Allocated expenses were $115,000 and $135,000 and $9,000 for
the period from January 1, 1997 through October 28, 1997, the year ended
December 31, 1996 and for the period from inception through December 31, 1995,
respectively.
 
     Sales and Marketing. Sales and marketing expenses were $67,000, $132,000
and $0 for the period from January 1, 1997 through October 28, 1997, the year
ended December 31, 1996 and for the period from inception through December 31,
1995, respectively. Sales and marketing, as a percentage of net revenues were
6%, 22% and 0%, for the period from January 1, 1997 through October 28, 1997,
the year ended December 31, 1996 and for the period from inception through
December 31, 1995, respectively. Sales and marketing expenses decreased due to a
reduction in advertising costs associated with the initial promotion of the Web
site in 1996 and 1995. During 1997, substantially all sales and marketing
efforts were outsourced to a third-party firm in order to reduce costs
associated with maintaining an internal staff.
 
Interest Expense
 
     DBC funded the working capital requirements of the DBC Online/News Business
division based upon a centralized cash management system. Interest expense was
$181,000, $90,000 and $9,000 for the period from January 1, 1997 through October
28, 1997, the year ended December 31, 1996 and the
 
                                       26
<PAGE>   27
 
period from inception (October 1, 1995) through December 31, 1995, respectively.
The amounts due to DBC totaled $2.7 million at October 28, 1997 and interest on
amounts due to DBC is charged at The Chase Manhattan National Bank's prime plus
2% (10.50% at October 28, 1997).
 
INCOME TAXES
 
     No benefit for federal and state income taxes is reported in the financial
statements as MarketWatch.com has elected to be taxed as a partnership prior to
the merger of the limited liability company into a corporation. Therefore, for
the periods presented, the federal and state tax effects of the our tax losses
were recorded by the members of the LLC in their respective income tax returns.
Subsequent to the Reorganization, we will account for income taxes in accordance
with Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" ("SFAS No. 109"). Had we applied the provisions of SFAS No. 109 for the
period from inception (October 29, 1997) through December 31, 1997, the deferred
tax asset generated, primarily from net operating loss carryforwards, would have
been offset by a full valuation allowance.
 
     The DBC Online/News Business has accounted for income taxes in accordance
with SFAS No. 109. The operating losses of the DBC Online/News Business were
included in the consolidated tax returns of DBC and were used to offset taxable
income. Therefore, the DBC Online/News Business has reflected a current tax
benefit related to these tax losses.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Since inception on October 29, 1997, we have funded our operations
primarily from cash contributed and advanced by DBC and from revenues from
advertising sales. DBC contributed capital of $218,000 and $782,000 to us during
the period from inception (October 29, 1997) through December 31, 1997 and the
nine months ended September 30, 1998, respectively. As of September 30, 1998, we
had a working capital deficit of $3.9 million. Under the terms of the
Contribution Agreement, we received an additional $1.0 million capital
contribution from DBC on October 28, 1998.
 
     Cash used in operating activities was $2.9 million for the nine months
ended September 30, 1998 compared to $205,000 for the period from inception
(October 29, 1997) through December 31, 1997. Significant uses of cash in
operations for the nine months ended September 30, 1998 include costs associated
with increased sales and marketing activities to establish and to promote our
products and services and increased accounts receivable and deferred offering
costs, offset by accrued expenses for the costs of this offering.
 
     Cash used in investing activities was $889,000 for the nine months ended
September 30, 1998 compared to $13,000 for the period from inception (October
29, 1997) through December 31, 1997 and primarily reflects capital expenditures.
Cash from financing activities were $3.8 million for the nine months ended
September 30, 1998 compared to $218,000 for the period from inception (October
29, 1997) through December 31, 1997 and primarily reflects contributions and
advances from DBC.
 
     Capital expenditures were $889,000 for the nine months ended September 30,
1998 and $13,000 for the period from inception (October 29, 1997) through
December 31, 1997. The company does not have any commitments for capital
expenditures at September 30, 1998. However, as of September 30, 1998, we had
commitments under noncancellable operating leases of $1.5 million through March
31, 2003. In addition, under the terms of our agreements with Yahoo!, we are
committed to make payments for advertising and slotting of $870,000 through
1999. Upon completion of this offering, the minimum commitment increases from
$870,000 over a twelve month period to $1.6 million over a twelve month period,
beginning upon the closing of this offering. In addition, we are obligated to
pay Yahoo! a fee based on the amount of traffic directed to our Web site.
 
     To date, we continue to be substantially dependent on DBC for almost all of
our financial, administrative and operational services and related support
functions including cash management.

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
the infrastructure.
 
     Under the terms of the Limited Liability Company Agreement of the LLC
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 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, 1998, advances from DBC
were $3.0 million. We intend to use a portion of the net proceeds from this
offering to repay all outstanding advances from DBC. In addition, DBC
contributed $1.0 million to us in October 1998. See Note 7 to our financial
statements.
 
     At October 28, 1997 the DBC Online/News Business owed DBC $2.7 million for
working capital advances which we have not assumed. Subsequent to October 28,
1997, the amounts due to DBC by the DBC Online/News Business have been reduced
by the collection of accounts receivable existing prior to our formation. Any
remaining obligation has remained unpaid. See Note 3 to the predecessor
financial statements.
 
     We expect to incur significantly higher costs, particularly content
creation costs, and sales and marketing costs, in the future to grow our
business. We believe that the net proceeds from this offering, together with our
current cash and cash equivalents and commitments and borrowings from DBC, will
be sufficient to meet our anticipated cash needs for working capital and capital
expenditures for at least the next 12 months following the offering. Thereafter,
if cash generated from operations and borrowings under the DBC Credit Agreement
are insufficient to satisfy our liquidity requirements, we may need to raise
additional funds through public or private financing, strategic relationships or
other arrangements. There can be no assurance that such additional funding, if
needed, will be available on terms attractive to MarketWatch.com, or at all.
Strategic relationships, if necessary to raise additional funds, may require us
to provide distribution or rights to certain of its technologies. The failure to
raise capital when needed could have a material adverse effect on our business,
operating results and financial condition. If additional funds are 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 described under "Description of Capital Stock -- Rights of First Refusal,"
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 the Common Stock.
 
YEAR 2000 READINESS DISCLOSURE
 
     We rely on DBC's computer and communications networks for the operation of
its Web site, and on DBC's information systems for customer billing, accounting
and administration. 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. DBC is currently installing new billing,
accounting and administrative systems which are scheduled to be fully
operational during 1999 and which have been represented will be fully year 2000
compliant when fully operational. 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 compliance testing completed and
ongoing, 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. We also rely on
solutions provided by Doubleclick for the delivery of its advertising and
 
                                       28
<PAGE>   29
 
user measurement. We have been informed by them that their solutions are, or
will be, year 2000 compliant in all material respects.
 
     We have made no investigation of any of our embedded systems, such as
electrical, heating or telephones. However, if any year 2000 issues arose with
respect to these systems, we do not expect that they would have any materially
adverse effect on our business in the long term.
 
     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. Furthermore, the
purchasing patterns of 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 of operations and financial condition.
 
     We do not presently have a contingency plan for handling year 2000 problems
that are not detected and corrected prior to their occurrence. DBC has advised
us that it has developed certain contingency options in the event of a failure
due to year 2000 issues. Any failure to address any Year 2000 issue could
adversely affect our business, financial condition and results of operations. 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 had in the past. However, we may not be able to replace
DoubleClick with another vendor on reasonable terms, or we delivered advertising
ourselves, we would not be able to track or measure the advertising to the same
extent as DoubleClick.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131 ("SFAS 131"), "Disclosure about Segments
of an Enterprise and Related Information." SFAS 131 establishes new standards
for the way companies report information about operating segments in annual
financial statements. The disclosures prescribed by SFAS 131 are effective for
the year ending December 31, 1998. We do not believe it operates in more than
one segment.

     This Prospectus contains forward-looking statements that involve risks and
uncertainties. Our actual results may differ significantly from the results
discussed in these forward-looking statements. Factors that may cause such a
difference include, but are not limited to, those discussed in "Risk Factors."
Ownership of our securities by CBS or DBC should not be viewed as a
recommendation by either company to acquire or hold the Common Stock.
 
INDUSTRY BACKGROUND
 
     The Web as a New Medium
 
     The Web has rapidly become a significant global medium for communications,
news, information and commerce. Jupiter Communications, a new media research
firm which specializes in online research and analysis, estimates that the
number of Web users worldwide will grow from approximately 85 million at the end
of 1997 to approximately 250 million by the end of 2002. This growth is being
driven by a number of factors, including a growing base of PCs in the home and
workplace, improvements in network infrastructure, more convenient, faster and
inexpensive Internet access, advances in PCs and modems, increases in the
quantity and quality of content available on the Web and the overall increased
public awareness of the Web. The Web has also become an attractive medium for
advertisers, offering a level of targetability, flexibility, interactivity and
measurability not available in traditional media. Jupiter Communications
estimates that the amount of Web advertising in the U.S. will grow from $940
million in 1997 to over $7.6 billion by the year 2002. By advertising on the
Web, advertisers have the ability to gather demographic information and target
their messages to specific groups of consumers as well as to change their
advertisements frequently in response to market factors, current events and
consumer feedback. Moreover, advertisers can track more accurately the
effectiveness of their advertising messages by receiving reports of the number
of advertising "impressions" delivered to consumers, and the resulting "hit" or
"click through" rate to their Web sites.
 
     The Web allows content providers to deliver information and programming in
a manner not possible in the traditional broadcast and print media. Although
these traditional media can have large audiences, they are generally limited to
a specific geography, can deliver only limited content or are not effective in a
real-time environment. Print media is limited by the significant time delays
involved in its production and distribution and its inability to be updated on a
real-time basis. Broadcast media is limited by the relatively small number of
available frequencies or channels, the rigidity of its schedules and its
inherent capacity constraints, with each channel or frequency carrying only a
limited amount of information. By comparison, the Web allows users to rapidly
access, search and interact with a rich repository of content, regardless of
their location. In addition, despite the large amount of undifferentiated
information on many Web sites, users can utilize and manipulate information more
efficiently than in traditional media by conducting real-time, customized
searches.
 
     Demand for Business News and Financial Programming
 
     A number of trends have led to increased demand for comprehensive business
news and financial programming in all forms of media:
 
     - individuals are proactively managing their money and the American public
is investing an increasing percentage of their household wealth in securities;
 
     - the emergence of online trading of financial instruments has led many
investors to rely less on traditional brokers; and
 
     - U.S. companies increasingly compete globally, requiring increased
real-time knowledge of a broad range of financial information from around the
world.
 
                                       30
<PAGE>   31
 
     Business Week reports that more than 70 firms now offer online trading, up
from approximately 30 at the end of 1997, including most of the major U.S.
stockbrokers, with The Charles Schwab Corporation reporting that 52% of its
trading volume in the quarter ended June 30, 1998, was conducted online.
According to Business Week, Forrester Research, a publicly traded independent
research firm which provides analysis of a range of technology industries,
predicts that there were over three million online investing accounts at the end
of 1997, and Forrester Research predicts that this number will increase to 14.4
million by 2002.
 
     Driven by these factors, numerous traditional and online information
sources such as newspapers, magazines, broadcasters and specialized financial
Web sites are seeking to address the demand for timely and relevant financial
information. However, these companies are often unable to meet effectively
consumers' needs for high-quality, compelling and relevant, real-time business
information. Newspapers and magazines cannot offer real-time data and
information, and broadcasters are limited in the depth and availability of their
content. While there has been a proliferation of Web sites which include
financial information as part of their offerings, MarketWatch.com believes that
most sites offering such financial data suffer from a number of limitations.
Frequently, these sites do not offer high quality original content comparable to
that available from the best traditional financial media sources and do not
offer readily available tools on an organized, real-time basis. Furthermore,
these sites often offer large, undifferentiated collections of information that
require users to undertake time-consuming and multi-site searches to obtain all
of the information and tools they need.
 
     MarketWatch.com believes that a significant opportunity exists for a
company to provide easy access to real-time business news, financial programming
and analytic tools over the Internet. By integrating high quality editorial
content with the best available financial tools and data, a Web-based service
can enable its audience to keep abreast of current business developments, track
industry and competitive trends, make informed investment decisions and manage
their financial assets. MarketWatch.com believes that by assembling a loyal base
of users who actively follow business and financial news, a Web site can create
a targeted and demographically-desirable audience that is attractive to
financial and non-financial advertisers.
 
THE MARKETWATCH.COM SOLUTION
 
     Through our CBS.MarketWatch.com Web site, we are a leading Web-based
provider of comprehensive, real-time business news, financial programming and
analytic tools. The CBS.MarketWatch.com Web site presents clear, original,
authoritative and timely business coverage created in real-time by its team of
experienced business and financial journalists and commentators, our Web site
incorporates in-depth features and columns, market data feeds and sophisticated
analytical tools. Our experienced editorial staff presents our content in a
well-organized and approachable fashion, thereby enabling our audience to keep
abreast of current business developments, track competitors, make informed
investment decisions and manage their financial assets.
 
     We believe our strategic relationships with our principal investors, CBS
and DBC, allow us to differentiate our Web site as the preeminent brand for
real-time business news and financial programming on the Web. CBS will provide
us with $30 million rate card amount of television network and radio advertising
and promotion over the period from October 29, 1997, through October 29, 2002,
and will provide credibility with advertisers, its audience, and potential
business partners. DBC supplies us with a ready-made infrastructure for the
CBS.MarketWatch.com Web site, access to multiple domestic and international data
feeds and sophisticated analytic tools. We believe that the ongoing development
of a "one-stop-shop" for financially-oriented programming, news and data will
help establish the CBS.MarketWatch.com Web site as one of the premiere Web
sites.

STRATEGY
 
     Our objective is to create the leading branded Web site for comprehensive
real-time business news, financial programming and analytic tools. This strategy
is designed to maximize the quantity and quality of traffic on the
CBS.MarketWatch.com Web site and to develop a strong and loyal community,
thereby creating an audience which is highly attractive to companies advertising
and engaging in commerce over the Internet. Our strategy to achieve this
objective includes the following key elements:
 
     Build Traffic and Audience Loyalty. We believe that the CBS name and logo,
the advertising and promotion we receive from CBS, and our plans for
significantly increased marketing activities will provide us with increased
visibility among Web users and companies advertising and engaging in commerce
over the Internet. Additionally, we are aggressively pursuing distribution
relationships with high-traffic Web sites to strategically place its programming
and links to its Web site as another key element in building traffic. For
example, certain of our headlines are listed on Yahoo!, with links back to the
CBS.MarketWatch.com Web site for the full story. We are also seeking to build
our traffic with a national brand building campaign in traditional and online
media.
 
     Deliver Original, Authoritative and Timely Programming with High Editorial
Value. MarketWatch.com will continue to cover the financial markets and other
areas of interest to its audience and aggressively enhance this programming by
expanding its staff of journalists, columnists and selected third-party content.
Led by two experienced business journalists, Larry Kramer and Thom Calandra, our
editorial staff creates real-time, high quality news stories that inform,
educate and entertain its audience. Our editors continuously update the
CBS.MarketWatch.com site's "Front Page" throughout the trading day to emphasize
the most important stories of the moment. We believe that the journalistic
background of much of our senior management and their commitment to providing
compelling news stories offers us a significant competitive advantage.
 
     Leverage CBS's Name Recognition and Resources. We believe that our
strategic relationship with CBS helps attract users, facilitate advertising
sales and obtain interviews with high-profile personalities. We seek to leverage
this relationship and use the CBS name and logo in our marketing and throughout
the site. We also benefit from the prominent usage of our logos and URL during
CBS Television and Radio broadcasts, including the CBS Evening News, which
reaches approximately 10.2 million persons each weeknight according to the
National Nielsen Ratings for the television season through August 1998. In
addition, MarketWatch.com correspondents currently appear, and our content is
distributed, on the CBS Television Network and radio news programming. The
distribution of such content, and the usage of our logo and URL, occur through
an understanding we have with CBS. However, CBS is under no obligation to
continue this arrangement, and there can be no assurance that this arrangement
will continue in the future.
 
     Leverage DBC's Data and Analytic Tools. MarketWatch.com's strategic
relationship with DBC provides access to in-depth, real-time and historical data
from all of the major U.S. securities markets as well as sophisticated and
proprietary software tools for analyzing and manipulating such data. We
integrate such data and analytic tools with our news content to provide users a
differentiated and effective service. DBC hosts the CBS.MarketWatch.com Web site
and provides the necessary engineering and network infrastructure to support the
Web site's operations at DBC's marginal cost.
 
     Build and Capitalize on Attractive Audience Demographics. We believe our
Web site attracts users who as a group are more affluent and better educated
than users of many other Web sites and therefore represents an attractive medium
for companies that advertise and engage in commerce over the Internet. In order
to attract new users and grow a loyal audience that appeals to a broad range of
advertisers and business partners, we are investing in content, improved and
expanded features and advertising and promotional programs. We believe that this
strategy has helped to attract new advertisers on the CBS.MarketWatch.com Web
site including popular consumer brands such as American Airlines, AT&T, DeBeers,
Ford, Sprint, Toyota and Volvo.
                                       32
<PAGE>   33
 
     Pursue Additional Revenue Streams. We believe we have significant
opportunities to capitalize on our audience and content offerings to create
multiple revenue streams for future growth. In addition to advertising revenues,
we currently offer limited subscription services for certain market data and
analyst reports and intend to offer additional subscription services, such as
exclusive news, commentary and analytic tools. We are also aggressively pursuing
electronic commerce opportunities through strategic and marketing relationships
with retailers and service providers focused on Web distribution. For example,
we believe that our focused content and audience provides us with excellent
opportunities to build strategic commerce relationships with financial service
companies, such as marketers of credit cards, consumer and home loan companies
and insurance providers. We also believe that an opportunity exists to leverage
the MarketWatch.com brand and create strategic relationships in key
international markets.
 
THE CBS.MARKETWATCH.COM SITE
 
     The CBS.MarketWatch.com Web site is a comprehensive business and financial
Web site providing up-to-the-minute business news, financial programming and
analytic tools. Our staff of approximately 40 professional journalists,
including freelance journalists, offers real-time coverage of business and
financial news and in-depth commentary on market moving trends and events. We
also offer a wide range of other financial information and subscription services
as well as community features to provide a "one-stop-shop" for our audience.
Recent additions to the CBS.MarketWatch.com Web site include columns by
well-known commentators, enhanced personal portfolio tracking features, hosted
chat rooms, bulletin boards and messaging. We believe that offering
comprehensive business news, financial programming and analytic tools is
critical to its success as it enables us to increase audience loyalty and sense
of community, average usage time and repeat visits.
 
     News and Editorial Content
 
     The CBS.MarketWatch.com front page is carefully designed and regularly
updated throughout the trading day by our journalists and editors to inform our
audience of the important stories of the moment. Unlike many of our Web-based
competitors, we do not rely exclusively on automatic editing and display
systems; instead we leverage our journalistic expertise to add a strong
editorial framework to our content. From the CBS.MarketWatch.com Web site's
"front page," users can access news stories, columns and headlines written by
its reporters and third parties, such as Reuters, Associated Press, and PR
Newswire, as well as stock quotes and other business and financial data and
analytic tools. The CBS.MarketWatch.com Web site also offers limited audio and
video clips of news reports that were recently broadcast on the CBS Television
Network and CBS Radio by our correspondents. Users can also search a historical
database of news stories by company name and ticker symbol.

     We create and publish on the CBS.MarketWatch.com Web site real-time

and edits the CBS.MarketWatch.com Web site's mutual fund section. The Mutual
Fund Center section offers Lipper Mutual Fund Profiles and provides links to
other mutual fund listings, news headlines, quotes and charts. The
CBS.MarketWatch.com Web site also offers a "Fund University" section, which
provides various mutual fund educational information and links to other mutual

packages.

the leading names in research and news, such as Baseline, Hoover's, Inc.,
INVESTools, Inc., Investor Communications Business Inc. and Zacks Inc. We
receive a portion of any revenue generated from the sale of these products or
services, however, to date, we have not received material revenue from these
sources. Our reporters and editors also use information provided by these

     Securities Price Quotes. Utilizing data gathered and packaged for online
use by DBC customers, the CBS.Marketwatch.com Web site provides stock quotes
from all major U.S. stock markets. These quotes are offered on a minimum delay
of 15 minutes in the United States in accordance with exchange rules, and of
varying periods from foreign markets. Users can also subscribe to real-time
quote services, MarketWatch RT and MarketWatch Live, through the Web site.
Through these stock quote pages, our audience can link to other valuable
information about a particular company, including related MarketWatch.com news
stories, stories from other news services, summaries of SEC filings and annual
reports, summaries of analysts' information and a variety of fundamental and
technical information about its stock. The CBS.MarketWatch.com Web site also
provides information as to various market and industry indices, commodity
contracts and currency exchange rates.
 
     Portfolios. In an effort to offer the most complete and functional
portfolio tracking system on the Web, the CBS.MarketWatch.com Web site has a
sophisticated portfolio tracking service which offers a variety of features,
including the ability to:
 
     - track up to 200 ticker symbols in multiple portfolios;
 
     - access portfolios from any computer with Web access;
 
     - track options, mutual funds and stocks on all major U.S. and
       international exchanges;
 
     - monitor portfolios over a secure connection;
 
     - automatically update portfolio price views every five minutes; monitor
       short and long positions;
 
     - view transaction history and capital gains reports; and
 
     - download portfolio reports for use in spreadsheets, thus providing a
       wider set of choices for record-keeping.
 
     We are also developing additional features, such as an email alert when one
of a user's portfolio securities trades out of its normal range and
end-of-the-day emails summarizing the portfolio's activity that day. This
service is offered free of charge and users can enroll by completing a simple
online registration form.
 
     Data. The CBS.MarketWatch.com Web site offers a wide variety of data
including trading volume and dollar volume information, corporate share
repurchases, industry and customized local CBS affiliate indices, stock split
information and other data related to global and currency markets.
 
     Analytics. We have developed real-time news products utilizing proprietary
analytical tools. These services typically generate thousands of daily,
real-time headlines based on individual stock
 
                                       35
<PAGE>   36
 
activity. If, for example, a stock exhibits unusual volume or price activity,
the software generates a real-time headline that alerts investors to that
activity. The CBS.MarketWatch.com Web site also provides information relating to
fixed-income securities and commodities.
 
     Community Features
 
     We believe that providing a place for our audience, financial journalists
and experts in the financial world to meet and share ideas about investing will
help increase brand awareness, motivate users to return to the
CBS.MarketWatch.com Web site frequently and encourage our audience to spend more
time on its Web site. Additionally, because we intend to integrate related news,
market data and charts offered throughout our service, community members will be
able to gravitate towards others who share their specific interests, enabling
them to create niche user groups which can be targeted with relevant marketing
campaigns and transaction opportunities. In addition, because we plan to
integrate other content with these community features, community members will be
exposed to other areas of the site, increasing the awareness of the breadth of
our programming and other services. We believe that the personal and interactive
nature of communicating with other people who share similar interests will help
generate an affinity for the community and increased brand loyalty to
MarketWatch.com.
 
     Currently, we offer a bulletin board service where users can discuss
investments. In the first quarter of 1999, we intend to launch an array of
communication tools designed to facilitate the creation of a much larger and
more dynamic community. This suite of tools is intended to provide our audience
with the means for communicating either privately, using Web-based email and
instant messaging, or in affinity group message boards and chat rooms. In order
to participate and to assist us in targeting its advertising, users must
complete registration forms and provide demographic information about
themselves.
 
     Our community building efforts are centered on strengthening audience
loyalty, increasing page views across all areas of the site, and providing
opportunities for premium sponsorships, such as sponsoring moderated chat
events. Longer term, as we gather more information about the interests of its
community members, it intends to offer targeted advertising in specialized
discussion groups within the community and pursue electronic commerce
relationships with the goal of entering into revenue sharing relationships based
on transactions derived from community members.
 
EDITORIAL
 
     We maintain news bureaus in New York City, Washington D.C., San Francisco,
Los Angeles and London, England. Our journalists generate between 400 and 600
finance and business-related, real-time headlines on an average trading day. We
have also devoted additional staff to cover special areas of interest, including
initial public offerings, the fixed income markets, futures and options and
technology stocks. Also, we intend to expand our industry-based and real-time
capital markets coverage. For example, we recently added columns which cover the
telecommunications and the sports industries and introduced a "spot news" desk
to cover the major relevant stories of the day. MarketWatch.com also receives
live media feeds from PR Newswire and Business Wire, and has access to all major
financial wires and broadcast channels. We also work with CBS News' global
operations and presence to expand our coverage of international business and
financial news. In addition to providing news coverage for the
CBS.MarketWatch.com Web site, our journalists provide financial news to CBS
Television News and CBS Radio news programming. We believe that by providing
news reports for CBS and working with CBS News journalists, it will have the
opportunity to enhance our reputation and audience reach.
 
     Our staff of over 40 professional journalists, including freelance
journalists who write for us, are experienced editors, bureau chiefs and
reporters with high standards for reporting and editing. We believe our staff
provides us with a significant competitive advantage. For example, Larry Kramer,
our Chief Executive Officer, was Executive Editor of the San Francisco Examiner,
and a financial
 
                                       36
<PAGE>   37
 
reporter and Metro Editor of The Washington Post. Our staff also includes Thom
Calandra, our Editor-in-Chief, who has been a financial columnist for the San
Francisco Examiner, the London-based, lead markets editor for Bloomberg News and
Online Money Editor for USA Today Online; Paul Erdman, a renowned economist and
author; and Irwin Kellner, a former Chief Economist for Manufacturers Hanover
Trust Bank; as well as a number of other journalists who previously worked for
Bloomberg News, Associated Press, UPI, CBS Radio news, Fox News Internet and Dow
Jones Television. We believe that we are one of the few Web-based companies
which offers this level of journalism.
 
ADVERTISING AND SALES
 
     We are focused on providing our advertisers with a large, demographically
desirable audience. We believe that our Web site attracts users who as a group
are more affluent and better educated than users of many other Web sites and
therefore represents an attractive medium for companies that advertise and
engage in commerce over the Internet. Advertisements are displayed throughout
the Web site, when a user enters the service, reviews a news story or accesses a
quote or portfolio. Advertising revenues represented 56%, 59%, 68% and 74% of
our net revenues for the period from our inception (October 29, 1997) through
December 31, 1997 and the quarters ended March 31, June 30, and September 30,
1998, respectively.
 
     Prior to January 1998, we used a third-party service to sell advertising on
our Web site. We are building a direct sales force, which, as of November 30,
1998, consisted of fourteen members. We believe that having an internal direct
sales force allows us to better understand and meet advertisers' needs, increase
our access to potential advertisers and maintain strong relationships with our
existing advertising clients. Our in-house sales staff includes experienced
Internet sales personnel as well as those from traditional media. The staff
develops and implements its advertising strategies by creating value-added
packages for advertisers from the wide range of news columns, editorial opinions
and other tools and information on the CBS.MarketWatch.com Web site, including
identifying strategic accounts and developing presentations and promotional
materials and building relationships with advertising buyers. DoubleClick
provides advertising management and delivery services for the
CBS.MarketWatch.com Web site and provides advertisers with reports describing
the delivery of their advertisements. See "Risk Factors -- Risks Related to Our
Industry -- Risks Associated with Web Advertising."
 
     We currently derive, and expect to continue to derive, a substantial
majority of our revenue from advertising sales. We offer a variety of
advertising options that may be purchased individually or in packages such as
"run of site," targeted advertising and sponsorships. Currently we offer the
following advertising options on the CBS.MarketWatch.com Web site:
 
        Run of Site. Run of site rotations are banner advertisements that rotate
     on a random basis throughout the CBS.MarketWatch.com Web site, appealing to
     advertisers seeking to establish general brand recognition across
     MarketWatch.com's audience. Run of site rotations are typically sold in
     blocks of 1,000 impressions and generally are sold with a minimum of
     100,000 guaranteed impressions over the life of the advertising contract.
     MarketWatch.com's current rate card CPM ranges from $25 to $35 depending on
     length of contract and number of impressions purchased.
 
        Targeted Advertising. Targeted advertisements are banner advertisements
     that are displayed when a user browses through specific news and quote
     pages, allowing advertisers to target users based on ticker symbols
     requested or by specific areas of interest by advertising on particular
     columns. Advertisers can also deliver their advertisements by region or
     country, time of day, frequency of use, Internet Service Provider, type of
     operating system or browser. Like run of site rotations, targeted
     advertisements are sold in blocks of 1,000 impressions. Due to the greater
     selectivity of the audience and because users typically spend more time on
     news pages than on quote pages, MarketWatch.com's current rate card CPM for
     targeted advertisements is generally higher than for run of site rotations,
     generally ranging from $25 to $50. In order to
 
                                       37
<PAGE>   38
 
     enhance the effectiveness of ad targeting, we are building a database of
     our registered users through an email newsletter and securities portfolio
     tracking service.
 
        Sponsorships. Sponsorships allow advertisers to gain maximum exposure on
     the MarketWatch.com site by featuring "buttons" on certain pages. For
     example, seven online brokerage services (Datek, DLJ Direct, First Trade,
     Mr. Stock, ScoTTrade, Trading Direct and Web Street Securities) have
     purchased premium sponsorship placements to gain fixed positions within the
     CBS.MarketWatch.com Web site and thereby present a user with the
     opportunity to move directly to the advertisers site to establish an
     account or place an order. We offer other sponsorship opportunities
     throughout our entire site. Sponsorships are typically sold for a fixed
     monthly fee over the life of the contract and may include other advertising
     components such as general rotation or targeted banner advertisements.
 
        Content Sidebars. MarketWatch.com also offers fixed location bars, or
     content sidebars, on selected high traffic pages to provide advertisers
     with greater visibility in order to feature an advertiser's content,
     information or tools. MarketWatch.com typically charges premium rates for
     the placement of these content sidebars. Content sidebars can also be sold
     as part of a sponsorship arrangement.
 
     Historically, MarketWatch.com's advertisers have been from the technology
and financial services industry, but we have recently attracted advertisers from
brands outside of these industries, such as American Airlines, Bell South,
DeBeers, Sprint, Toyota and Volvo. MarketWatch.com believes that attracting
additional advertisers from businesses outside of the financial and technology
industries is important to our future success and revenue growth. See "Risk
Factors -- Risks Related to Our Business -- Dependence on Financial Industry
Advertisers." From November 1, 1997, through November 30, 1998, more than 100
organizations, including the following, have advertised on our Web site:

STRATEGIC RELATIONSHIPS
 
     We believe that our strategic relationships with our principal investors,
CBS and DBC, allow us to differentiate the CBS MarketWatch.com Web site as the
preeminent brand for real-time business news and financial programming on the
Web.
 
                                       38

     CBS
 
     License. In connection with the formation of the LLC, the LLC entered into
a five-year license agreement under which the Web site was renamed
"CBS.MarketWatch.com" and the LLC was granted the right to use the CBS name and
logo as well as CBS Television Network news content in connection with the
CBS.MarketWatch.com Web site during this period. This agreement, as it was
amended and restated immediately prior to the effectiveness of this offering,
which we call the Amended and Restated License Agreement, will expire on October
29, 2005. Under the terms of the Amended and Restated License Agreement,
MarketWatch.com will pay CBS a percentage of Gross Revenues generated by the
CBS.MarketWatch.com Web site. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations." The Amended and Restated License
Agreement will be subject to termination in the event that competitors of CBS
acquire specified amounts of our Common Stock and in other events. See "Certain
Transactions" for descriptions of events which could cause a termination of this
agreement. Subject to certain limitations, CBS will provide us with an aggregate
rate card amount of $30 million of network television, radio and Internet
advertising and promotion commencing from October 1997 through October 2002.
Internet advertising will be limited to five percent of the total promotion
delivered. CBS could terminate this advertising obligation if the Amended and
Restated License Agreement is terminated. See "Risk Factors -- Risks Related to
Our Relationship with CBS and DBC -- Dependence on CBS Relationship" and
"Certain Transactions" for a description of certain material risks associated
with the Amended and Restated License Agreement.
 
     Reporting. We believe we can increase our brand awareness by providing
financial news reports for CBS News and CBS Radio. Our New York City-based
bureau is located in CBS facilities and frequently works with CBS News staff to
generate stories for distribution over the CBS broadcast networks. We have two
television correspondents who file daily reports on CBS Up-to-the-Minute
overnight programming and CBS Newspath, which supplies CBS News video to CBS
affiliated television stations for use in their news programs. Both
correspondents also file customized daily reports to major CBS affiliates via
satellite links, and contribute to the CBS Morning News. Our Editor-in-Chief,
Thom Calandra, files live weekday morning reports on KPIX-TV, the CBS owned
television station in San Francisco, and files reports with CBS in New York for
CBS News. Our correspondents often file reports on CBS Radio news programming,
covering breaking financial stories for the top-of-the-hour CBS Radio news
report that is broadcast over several hundred radio stations nationwide. In
addition, Frank Barnako, one of our reporters, does a twice-daily version of his
Internet Daily column for use by CBS Radio affiliates. We do not receive any
payments from CBS for this reporting. However, all reports delivered by our
correspondents are identified as our reports. Our correspondents file these
reports or provide services to CBS through an understanding we have with CBS
which we believe helps to strengthen our brand awareness. 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.
 
     Non-Competition Provisions. The Amended and Restated License Agreement will
contain certain limited non-competition provisions. However, these provisions
will have certain exceptions and will not otherwise provide for an exclusive
relationship. As a result, there can be no assurance that CBS will not promote,
establish or otherwise provide content for a Web site or Internet service which
competes with MarketWatch.com. See "Risk Factors -- Risks Related to Our
Relationship with CBS and DBC -- Potential Competition from CBS and DBC."
 
     We are critically dependent on our relationship with CBS. See "Risk
Factors -- Risks Related to Our Relationship with CBS and DBC -- Dependence on
CBS Relationship," "-- Control by CBS and DBC," "Management" and "Certain
Transactions."
 
     DBC
 
     Initial Contribution. At our formation, DBC contributed certain assets
related to its DBC Online/News Business which had been operating as departments
within DBC since October 1995.
                                       39
<PAGE>   40
 
In addition, DBC assigned agreements for advertising and content, portions of
its award-winning Web site, dbc.com, and its related trademarks, including
"MarketWatch" and the MarketWatch.com Internet domain name.
 
     Data and hosting. DBC currently provides delayed financial data to
MarketWatch.com at no charge. It also provides real-time financial data to
MarketWatch.com for dissemination to subscribers of certain of MarketWatch.com
subscription services in exchange for a percentage of the subscription fee. In
addition, DBC hosts and manages the CBS.MarketWatch.com Web site infrastructure
and provides 24x7 network support.
 
     General Services. DBC will also provide MarketWatch.com with certain
general services, including cash management, accounting services and human
resources services. MarketWatch.com will reimburse DBC for its actual costs of
providing these services.
 
     Payments for News. Under the Amended and Restated Services Agreement, DBC
will also pay 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 will contain certain non-competition
provisions, these provisions will have certain exceptions and do not provide for
an exclusive relationship. See "Risk Factors -- Risks Related to Our
Relationship with CBS and DBC -- Potential Competition from CBS and DBC,"
"-- Dependence on DBC Relationship" and "Certain Transactions."
 
MARKETING AND DISTRIBUTION
 
     We are seeking to establish the MarketWatch.com brand as the Web's leading
provider of business and financial information. CBS will agree to provide the
CBS.MarketWatch.com Web site with promotion and advertising with an aggregate
rate card amount of $30 million through October 2002. This promotion and
advertising will be carried or disposed on CBS Television Network programming,
programming on CBS owned and operated television and radio stations and/or
banner advertising on CBS Web sites over the period from October 29, 1997,
through October 29, 2002. These advertising placements may take the form of 30,
15 or 10 second units, scrolls of the CBS.MarketWatch.com URL, on-air mentioning
of our Web site, banner advertising and/or in credit rolls or sign-offs, with
CBS having broad discretion as to the type and manner of placement. As of
September 30, 1998, CBS had delivered $5.0 million rate card amount of promotion
and advertising under this commitment. See "Risk Factors -- Risks Related to Our
Relationship with CBS and DBC -- Dependence on CBS Relationship."
 
     CBS has displayed our MarketWatch.com logo and domain name on the CBS
Evening News with Dan Rather, CBS This Morning and on the news programming of
the CBS Television Network and many affiliated television stations. The logo is
usually displayed when business or financial news is covered during the
broadcast. When they occur, these promotional activities give the
CBS.MarketWatch.com Web site national promotion to the over 10.2 million people
who, according to recent national Nielsen Ratings for the television season
through August 1998, watch the CBS Evening News as well as the millions of
additional viewers of other CBS News broadcasts. CBS is not obligated to
continue to display our logo or domain name in this particular manner.
 
     We use journalists' appearances on CBS Television and Radio news broadcasts
and on certain affiliate station broadcasts to highlight the CBS.MarketWatch.com
Web site and increase the association of the Web site with CBS. When making
appearances, our journalist is identified with the
                                       40
<PAGE>   41
 
MarketWatch brand. The CBS.MarketWatch.com Web site is also linked directly to
the Web sites of CBS and many of its affiliate television stations. Each time a
user at these Web sites clicks on the "Money" section he or she receives a
graphic or story from the CBS.MarketWatch.com Web site or one of its
correspondents and a direct link to the CBS.MarketWatch.com Web site.
 
     In addition to our CBS-related promotional activities, we advertise on a
number of heavily trafficked Web sites, such as Yahoo!, Lycos, Excite and
AltaVista, and conduct a variety of other marketing and public relations
programs. These programs include paid advertisements in print publications and
radio broadcasts and participation in personal finance, online journalism and
Internet-related conferences. We intend to increase advertising and marketing
expenditures over their historical levels to continue to build awareness with
its audience. To this end, we launched a national brand building campaign and
intend to make substantial expenditures to advertise our brand and the
CBS.MarketWatch.com Web site in traditional and online media.
 
     We have entered into a number of, and are aggressively pursuing additional,
distribution relationships to enhance our brand name recognition and audience
reach. Key distribution relationships include:
 
        Yahoo! Inc. Yahoo! has agreed to index certain of the
     CBS.MarketWatch.com news headlines in the Finance section of Yahoo! with
     links to the CBS.MarketWatch.com Web site for the full story. In addition,
     we will advertise on Yahoo! over the 12 month period following the closing
     of this offering. We also have a content distribution relationship with
     Yahoo! under which we will provide at no charge a version of our Market
     Snapshot Report on a daily basis to registered users of the Investment
     Challenge fantasy investment game on Yahoo!'s Finance section.
 
        Quicken.com. Intuit has agreed to display certain of our news columns
     and features in portions of its Quicken.com Web site. We will receive a
     share of any revenues from the sale of advertising on the Quicken.com pages
     which display this content.
 
        Universal Feature Syndicate. In June 1998, we entered into an agreement
     with Universal Feature Syndicate under which Universal Feature Syndicate
     will market certain of the CBS.MarketWatch.com editorial features to
     newspapers exclusively in North America and non-exclusively throughout the
     world for syndication in print and electronic editions.
 
        News Alert. In March 1998, we entered into an agreement with News Alert,
     Inc. under which News Alert will provide certain third-party news feed
     collection, databasing and display services for the CBS.MarketWatch.com Web
     site. In addition, News Alert may also make certain of the
     CBS.MarketWatch.com editorial content available as a news feed to certain
     of News Alert's other customers.
 
        Brand Label Quotes Pages. We also seek to increase our revenues and name
     recognition by hosting co-branded financial information pages, or Brand
     Label Quotes Pages, accessible to visitors of other companies' Web sites
     who wish to retrieve market quotations and financial news. The presence of
     links on the Brand Label Quotes Pages to relevant MarketWatch.com news
     stories also helps drive traffic to the CBS.MarketWatch.com Web site. Web
     sites with these Brand Label Quotes Pages include Web sites operated by
     American Express Financial Direct, Callaway Golf, Cigar Aficionado, Conde
     Naste's cnCurrency.com, Hoover's Inc., IPO Monitor, National Discount
     Broker, Proctor & Gamble, Rocky Mountain News, Muriel Siebert & Co.,
     SportsLine USA, and Wine Spectator, among others. Generally, we sell
     advertising on portions of, and receive hosting fees for these pages. To
     date, revenues from these Brand Label Quotes Pages have constituted less
     than 10% of our aggregate revenues.
 
     We believe that distribution relationships of this type are important to
our continued growth and to increase our exposure to our target audience. We
intend to continue to aggressively pursue additional distribution relationships.
See "Risk Factors -- Risks Related to Our Business -- Need to Establish and
Maintain Strategic Relationships with Other Web sites."

SUBSCRIPTION SERVICES
 
     While substantially all of the programming available on the
CBS.MarketWatch.com Web site is currently free of charge, the
CBS.MarketWatch.com Web site offers subscription-based third-party financial
data services which are targeted for sophisticated investors. These services are
currently created and provided by DBC on a non-exclusive basis under a revenue
sharing arrangement. See "-- Strategic Relationships." MarketWatch.com is
developing and, in the future, intends to introduce additional subscription
services, such as exclusive news, commentary and analytic tools.
 
     We act or will act as DBC's sales agent with respect to the following DBC
services in exchange for a fee for new subscribers obtained through the
CBS.MarketWatch.com Web site:
 
     MarketWatch RT. MarketWatch RT is a browser-based, real-time financial data
service providing on demand real-time quotes from the American and New York
Stock Exchanges and NASDAQ. The service is available for a $34.95 monthly fee
which includes non-professional exchange fees of $12.50 for those three
exchanges. Premium research from Baseline is also available through this
service. DBC pays MarketWatch.com a monthly royalty for each subscriber. DBC
provides all customer and MIS support for this service. In August 1998, we began
marketing MarketWatch RT Wireless, a product for use with hand-held computing
devices such as Windows CE devices and Palm Pilots. In the future, we do not
expect to derive a material amount of revenue from this service.
 
     MarketWatch LIVE. MarketWatch LIVE is a Windows-based, real-time financial
data service providing "streaming" real-time quotes over the Internet from all
major US equity and futures exchanges. The base fee for this product is $79 per
month. Premium research from Baseline is also available through this service.
DBC pays MarketWatch.com a monthly royalty on revenues derived from this
service. DBC provides all customer and MIS support for this service. In the
future, we do not expect to derive a material amount of revenue from this
service.
 
     Our Web site also offers, for a fee, third party financial data and other
services through the Web site, such as Hoover's, Inc., which provides company
profiles, Zacks Inc., which provides company earnings estimates, and Baseline,
which provides company research reports. We receive a portion of the revenue
from the sale of these products or services through the CBS.MarketWatch.com Web
site. We do not currently and, in the future do not intend to, derive a material
amount of revenue from these services.
 
INFRASTRUCTURE, OPERATIONS AND TECHNOLOGY
 
     The CBS.MarketWatch.com Web site is hosted at, and all of its network
operations are controlled from, DBC's facilities in Hayward, California. DBC
provides multiple Web servers which run Microsoft Windows and Microsoft NT
operating systems and use Microsoft Internet Information Server. Internet access
is maintained through multiple DS3 connections with three different tier one
ISPs, UUNET, Digex and MCI. The computer equipment used to operate the
CBS.MarketWatch.com Web site at DBC's facilities is powered by multiple
uninterruptible power supplies. Our operations are dependent upon our ability to
protect systems against damage from fire, earthquakes, power loss,
telecommunications failure, break-ins, computer viruses, hacker attacks and
other events beyond our control. Our insurance policies have low coverage limits
and therefore our insurance may not adequately compensate us for any losses that
may occur due to any failures or interruptions in our systems. DBC is also
developing a redundant network operations center in Salt Lake City, Utah.
However, we do not presently have a formal disaster recovery plan.
 
     We are expanding our internal development group to create new, and enhance
existing, services, tools and features. For example, this group recently
developed a database portfolio application that, among other features, allows
users to track up to 200 ticker symbols each in multiple portfolios and view the
portfolio information through a secure connection. We are also developing an
advanced charting application which is designed to provide intraday ticker and
interval charts. We also utilize third-party technology for certain of its
services and tools. For
 
                                       42
<PAGE>   43
 
example, we licensed news database technology to allow users to search for news
stories from multiple third-party sources by ticker symbol, keyword and news
source. We have also entered into an agreement with a software development firm
that will provide a new community application system, with functionality such as
message boards, chat and instant messaging. As of September 30, 1998, we had
nine personnel dedicated to product and content development, and for the nine
months ended September 30, 1998, our product development expenditures were
$1,036,000.
 
     Our market is characterized by rapidly changing technology, evolving
industry standards and frequent new product announcements. These are exacerbated
by the recent growth of the Web and the intense competition in our industry. To
be successful, we must adapt to our rapidly changing market by continually
improving the performance, features and reliability of our services. We could
also incur substantial costs if we need to modify our services or infrastructure
in order to adapt to these changes. Our business could be adversely affected if
we incurred significant costs without adequate results or cannot adapt to these
changes.
 
COMPETITION
 
     The market for Internet services and products is relatively new, intensely
competitive and rapidly changing. The number of Web sites on the Internet
competing for consumers' attention and spending has proliferated and we expect
that competition will continue to intensify. We compete, directly and
indirectly, for advertisers, viewers, members and content providers with the
following categories of companies:
 
     - publishers and distributors of traditional off-line media, such as
       television, radio and print, including those targeted to business,
       finance and investing needs, many of which have established or may
       establish Web sites, such as The Wall Street Journal, CNN and CNBC;
 
     - general purpose consumer online services such as America Online and
       Microsoft Network, each of which provides access to financial and
       business-related content and services;
 
     - online services or Web sites targeted to business, finance and investing
       needs, such as TheStreet.com and Motley Fool; and
 
     - Web search and retrieval and other online services, such as Excite, Inc.,
       Infoseek Corporation, Lycos, Inc., Yahoo! Inc., and other high-traffic
       Web sites, such as those operated by Netscape Communications Corporation,
       which offer quotes, financial news and other programming and links to
       other business and finance related Web sites.
 
     We anticipate that the number of direct and indirect competitors will
increase in the future. This could result in price reductions for its
advertising, reduced margins, greater operating losses or loss of market share,
any of which would materially adversely affect our business, results of
operations and financial condition.
 
     Although the Amended and Restated License Agreement and Stockholders'
Agreement will contain non-competition provisions, these provisions will have
certain exceptions. As a result, there can be no assurance that CBS or DBC will
not promote, establish or otherwise provide content for a competitive Web site
or Internet service. See "Risk Factors -- Risks Related to Our Relationship with
CBS and DBC -- Potential Competition from CBS and DBC" and "Certain
Transactions."
 
     We believe our programming and content compete favorably with our
competitors, as many of them do not primarily provide real-time coverage by
experienced journalists. However, many of our existing competitors, as well as a
number of potential new competitors, have longer operating histories in the Web
market, greater name recognition, larger customer bases and higher amounts of
user traffic and significantly greater financial, technical and marketing
resources. Such competitors may be able to undertake more extensive marketing
campaigns, adopt more aggressive pricing policies, make more attractive offers
to potential employees, distribution partners, advertisers and content providers
and may be able to respond more quickly to new or emerging technologies and
 
                                       43
<PAGE>   44
 
changes in Web user requirements. Further, there can be no assurance that they
will not develop services that are equal or superior to ours or that achieve
greater market acceptance than our offerings. Increased competition could also
result in price reductions, reduced margins or loss of market share, any of
which could materially adversely affect our business, results of operations and
financial condition.
 
     The Web, and MarketWatch.com specifically, also must compete with
traditional advertising media, such as print, radio and television, for a share
of advertisers' total advertising budgets. Web companies and MarketWatch.com
would lose revenue if the Web is not perceived as an effective advertising
medium. As a result, there can be no assurance that we will be able to compete
successfully against its current or future competitors or that competition will
not have a material adverse effect on our business, results of operations and
financial condition. See "Risk Factors -- Risks Related to Our
Business -- Intense Competition for Web-Based Business and Financial Content."
 
INTELLECTUAL PROPERTY
 
     We rely primarily on a combination of copyrights, trademarks, trade secret
laws, our user policy and restrictions on disclosure to protect our intellectual
property, such as our content, trademarks, trade names and trade secrets. We
also enter into confidentiality agreements with our employees and consultants,
and seek to control access to and distribution of our other proprietary
information. Despite these precautions, it may be possible for a third party to
copy or otherwise obtain and use the content on our Web site or our other
intellectual property without authorization. There can be no assurance that
these precautions will prevent misappropriation or infringement of our
intellectual property. A failure to protect our intellectual property in a
meaningful manner could have a material adverse effect on our business,
operating results and financial condition. In addition, we may need to engage in
litigation in order to enforce our intellectual property rights in the future or
to determine the validity and scope of the proprietary rights of others. Such
litigation could result in substantial costs and diversion of management and
other resources, either of which could have a material adverse effect on our
business, operating results and financial condition.
 
     We license the CBS logo, name and certain news content from CBS pursuant to
the Amended and Restated License Agreement. This agreement could terminate in
certain circumstances and also involves a number of other risks. See "Risk
Factors -- Risks Relating to Our Relationships with CBS and DBC -- Dependence on
CBS Relationship."
 
     We also use certain licensed third-party technology, such as software from
DoubleClick, and data and content from third parties. In these license
agreements, the licensors have generally agreed to defend, indemnify and hold us
harmless with respect to any claim by a third party that the licensed software
or content infringes any person's proprietary rights. There can be no assurance
that the outcome of any litigation between such licensors and a third party or
between us and a third party will not lead to royalty obligations for which we
are not indemnified or for which such indemnification is insufficient, or that
we will be able to obtain any additional license on commercially reasonable
terms if at all. In the future, we may seek to license additional technology or
content in order to enhance our current features or to introduce new services,
such as certain of the community features we may introduce. There can be no
assurance that any such licenses will be available on commercially reasonable
terms, if at all. The loss of or inability to obtain or maintain any of these
technology licenses could result in delays in introduction of new services until
equivalent technology, if available, is identified, licensed and integrated,
which could have a material adverse effect on our business, results of
operations and financial condition.
 
     Because we license some data and content from third parties, our exposure
to copyright infringement actions may increase because we must rely upon such
third parties for information as to the origin and ownership of such licensed
content. We generally obtain representations as to the origins and ownership of
such licensed content and generally obtain indemnification to cover any
 
                                       44
<PAGE>   45
 
breach of any such representations. However, there can be no assurance that such
representations will be accurate or that such indemnification will be sufficient
to provide adequate compensation for any breach of such representations.
 
     There can be no assurance that infringement or other claims will not be
asserted or prosecuted against us in the future whether resulting from our
internally developed intellectual property or licenses or content from third
parties. Any future assertions or prosecutions could materially adversely affect
our business, results of operations and financial condition. Any such claims,
with or without merit, could be time-consuming, result in costly litigation and
diversion of technical and management personnel or require us to introduce new
content or trademarks, develop non-infringing technology or enter into royalty
or licensing agreements. Such royalty or licensing agreements, if required, may
not be available on acceptable terms, if at all. In the event of a successful
claim of infringement and our failure or inability to introduce new content or
trademarks, develop non-infringing technology or license the infringed or
similar technology on a timely basis, our business, results of operations and
financial condition could be materially adversely affected.
 
EMPLOYEES
 
     As of November 30, 1998, there were 61 personnel dedicated full time to our
business, ten of these personnel worked in product and content development, 17
in sales and marketing, 25 in editorial and nine in administration. Such
personnel are currently on the payroll of DBC and are provided to us pursuant to
the Original Services Agreement with DBC. Effective as of January 1, 1999, such
personnel became our direct employees. We have never had a work stoppage and no
personnel are represented under collective bargaining agreements. We consider
our employee relations to be good.
 
     We believe that our future success will depend in part on its continued
ability to attract, integrate, retain and motivate highly qualified sales,
technical, and managerial personnel, and upon the continued service of our
senior management and key sales and technical personnel. None of our personnel
is bound by an employment agreement that prevents such person from terminating
his or her relationship at any time for any reason. Competition for qualified
personnel is intense, particularly in the San Francisco Bay Area, where our
headquarters is located. At times we have experienced difficulties in attracting
new personnel. There can be no assurance that we will successfully attract,
integrate, retain and motivate a sufficient number of qualified personnel to
conduct our business in the future. See "Risk Factors -- Risks Related to Our
Business -- Need to Expand Our Business and Related Problems."
 
FACILITIES
 
     Our principal administrative, sales, marketing and research development
facilities are located in approximately 11,000 square feet of office space in
San Francisco, California leased from CBS. See "Certain Transactions." We
believe that our current facilities will be adequate to meet our needs for the
foreseeable future. All of our communications and network infrastructure is
hosted at DBC's facilities in the San Francisco Bay Area, with a redundant site
in Salt Lake City, Utah. Any system failure at these locations could lead to
interruptions, delays or cessations in service to users of the
CBS.MarketWatch.com Web site, which could have a material adverse effect on our
business, results of operations and financial condition. See "Risk
Factors -- Risks Related to Our Relationship with CBS and DBC -- Dependence on
DBC Relationship" and "-- Risks Related to Our Business -- Risk of Increased
Users Straining Our Systems and Other System Malfunctions."

"Board") will initially be comprised of seven directors. Directors are elected
by the stockholders of each annual meeting of stockholders or until their
successors are duly elected and qualified. Six of the initial directors will be
appointed pursuant to the provisions of the Stockholders' Agreement described in
"Certain Transactions." Each of CBS and DBC will have the right to designate for
election to the Board:
 
     - three candidates, so long as it holds at least 30% of our outstanding
       voting securities;
 
     - two candidates, so long as it holds at least 20% but less than 30% of our
       outstanding voting securities; or
 
     - one candidate, so long as it holds at least 1% of our outstanding voting
       securities.
 
     So long as the Amended and Restated License Agreement remains in effect,
CBS will also have the right to nominate at least one candidate to our Board of
Directors, regardless of the number of our voting securities held by it. If the
size of the Board is increased, CBS and DBC will each have the right to nominate
a number of candidates to the Board based upon the percentage of our
                                       48
<PAGE>   49
 
outstanding voting securities then held by them. In addition, each of CBS and
DBC will be obligated to vote the voting securities held by it for the other
party's designated candidates. See "Risk Factors -- Risks Related to Our
Relationship with CBS and DBC -- Control by CBS and DBC." All executive officers
are elected by, and serve at the discretion of, the Board.
 
BOARD COMMITTEES
 
     The Audit Committee has the responsibility to review audited financial
statements and accounting practices of MarketWatch.com, and to consider and
recommend the employment of, and approve the fee arrangements with, independent
accountants for both audit functions and for advisory and other consulting
services. The Audit Committee is currently comprised of Messrs. Imperiale and
DePalma. The Compensation Committee reviews and approves the compensation and
benefits for our key executive officers, administers our employee benefit plans
and makes recommendations to the Board regarding such matters. The Compensation
Committee is currently comprised of Messrs. Heyward and Hirschfield.
 
DIRECTOR COMPENSATION
 
     Directors are entitled to reimbursement of all reasonable out-of-pocket
expenses incurred in connection with their attendance at Board and Board
committee meetings. In October 1997, MarketWatch.com granted to Mr. Kramer a
non-plan option to purchase a membership interest in the LLC, which will
represent an option to purchase 200,000 shares of Common Stock, with an exercise
price per share of $4.00 after the Reorganization.
 
     In September 1998, the Board adopted, subject to stockholder approval, the
1998 Directors Stock Option Plan (the "Directors Plan") and reserved a total of
50,000 shares of Common Stock for issuance thereunder. Members of the Board who
are not our employees or of any affiliated company are eligible to participate
in the Directors Plan. Option grants under the Directors Plan are automatic and
nondiscretionary. The exercise price of such options is the fair market value of
the Common Stock on the date of grant.
 
     Each eligible director who first becomes a member of the Board on or after
the effective date of the Registration Statement of which this Prospectus forms
a part will be granted an option to purchase 10,000 shares. At each annual
meeting of stockholders, each eligible director will automatically be granted an
additional option to purchase 2,000 shares if he has served continuously as a
member of the Board since the date of such director's initial grant. The options
have 10 year terms. They will terminate seven months following the date the
director ceases to be a director or a consultant of MarketWatch.com, 12 months
if the termination is due to death or disability. All options granted under the
Directors Plan will vest as to 33 1/3% of the shares on each anniversary of the
option grant date. Additionally, immediately prior to the dissolution,
liquidation of MarketWatch.com or a "change in control" transaction, the vesting
of the options will accelerate and the options will be exercisable for a period
of up to seven months following the transaction. After that time any unexercised
options will expire.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Prior to this offering, our Board did not have a compensation committee and
all compensation decisions were made by the full Board. Mr. Kramer did not
participate in Board deliberations with respect to his compensation. Upon
completion of this offering, the Compensation Committee will make all
compensation decisions. No interlocking relationship exists between the Board or
Compensation Committee and the board of directors or compensation committee of
any other company, nor has any such interlocking relationship existed in the
past.

EMPLOYMENT CONTRACTS AND CHANGE OF CONTROL ARRANGEMENTS
 
     Pursuant to Messrs. Kramer and Bardwick's employment agreements, the
vesting of their stock options will be accelerated upon certain changes of
control of MarketWatch.com. See "Certain Transactions."

(1) Options granted in 1997 and 1998 were granted outside of any plan. These
    options become exercisable with respect to 33 1/3% of the shares subject to
    such option on each anniversary of the grant date. These options have a term
    of ten years. See "-- Employee Benefit Plans" for a description of the
    material terms of these options.
 
(2) Potential realizable value is based on the assumption that the Common Stock
    of MarketWatch.com appreciates at the annual rate shown, compounded
    annually, from the date of grant until the expiration of the ten-year term.
    These numbers are calculated based on Securities and Exchange Commission
    requirements and do not reflect our projection or estimate of future stock
    price growth. Potential realizable values are computed by
 
     - multiplying the number of shares of Common Stock subject to a given
       option by the exercise price, or in the case of the 0% column for Mr.
       Bardwick, by $14.00, the fair market value on the date of his grant, as
       determined by the Board of Directors;
 
     - assuming that the aggregate stock value derived from that calculation
       compounds at the annual 0%, 5% or 10% rate shown in the table for the
       entire ten-year term of the option; and
 
     - subtracting from that result the aggregate option exercise price.
 
(3) MarketWatch.com granted options to purchase aggregates of 446,250 and
    429,500 shares of Common Stock to all employees during 1997 and 1998,
    respectively.
 
(4) Options were generally granted at an exercise price equal to the fair market
    value of our Common Stock, as determined by the management committee of the
    LLC. In determining the fair market value of the Common Stock on each grant
    date, the management committee considered, among other things, the value of
    assets contributed to MarketWatch.com from DBC, MarketWatch.com's absolute
    and relative levels of revenues and other operating results, the state of
    MarketWatch.com's Web site development, increases in operating expenses, the
    absence of a public trading market for MarketWatch.com's securities, the
    intensely competitive nature of MarketWatch.com's market and the
    appreciation of stock values of a number of generally comparable Internet
    companies. See "-- Director Compensation," "-- Employment Contracts and
    Change of Control Arrangements" and "-- Employee Benefit Plans" for a
    description of the material terms of these options.

     No options were exercised during 1998 by the Chief Executive Officer or any
other executive officer of MarketWatch.com. No compensation intended to serve as
incentive for performance to occur over a period longer than one year was paid
pursuant to a long-term incentive plan during 1998 to the Chief Executive
Officer or any other executive officer of MarketWatch.com. MarketWatch.com does
not have any defined benefit or actuarial plan under which benefits are
determined primarily by final compensation and years of service with the Chief
Executive Officer or any other executive officer of MarketWatch.com.
 
EMPLOYEE BENEFIT PLANS
 
     Since October 1997, MarketWatch.com has issued options to purchase
membership interests in the LLC. In connection with the Reorganization,
outstanding options were assumed by MarketWatch.com and represent the right to
purchase shares of Common Stock rather than membership interests of the LLC.
Each such option will be converted into an option to purchase Common Stock based
upon a ratio of 1,000 shares of Common Stock for each 0.01% membership interest.
The options to purchase LLC membership interests outstanding on November 30,
1998 were converted into options to purchase 863,500 shares of Common Stock and
they would have a weighted average exercise price of $6.25 per share (assuming
the Reorganization occurred as of such date). These options will be subject to
terms substantially similar to those described below with respect to options to
be granted under the 1998 Equity Incentive Plan described below. Shares covered
by any outstanding option that expires unexercised become available again for
grant under the 1998 Equity Incentive Plan described below.
 
     1998 Equity Incentive Plan. In September 1998, the Board adopted, subject
to stockholder approval, the 1998 Equity Incentive Plan. The total number of
shares of Common Stock reserved for issuance thereunder is 1,450,000 less the
number of shares of Common Stock subject to non-plan options outstanding on the
date of this Prospectus. If all non-plan options to purchase LLC membership
interests outstanding on November 30, 1998 remain outstanding they will be
converted into options to purchase 863,500 shares of Common Stock. In that case,
586,500 shares of Common
 
                                       52
<PAGE>   53
 
Stock will be reserved for issuance under the plan. The plan will become
effective on the date of this Prospectus. Shares will again be available for
issuance under the plan that:
 
     - are subject to issuance upon exercise of an option granted prior to
       adoption of the plan (including shares subject to non-plan options
       outstanding on the date of this Prospectus) or under the plan that cease
       to be subject to such option for any reason other than exercise of such
       option;
 
     - have been issued pursuant to the exercise of an option granted under the
       plan with respect to which our right of repurchase has not lapsed and are
       subsequently repurchased by us;
 
     - are subject to an award granted under the plan that are forfeited or are
       repurchased by us; or
 
     - are subject to stock bonuses granted under the plan that otherwise
       terminate without shares being issued.
 
     This plan will terminate in September, 2008, unless sooner terminated in
accordance with the terms of the plan.
 
     The plan authorizes the award of options, restricted stock awards and stock
bonuses. No person can receive more than 400,000 shares in any calendar year
pursuant to awards under the plan. However, new employees can receive up to
500,000 shares in the calendar year in which such employee commences employment.
The plan will be administered by the Compensation Committee of the Board of
Directors. The committee has the authority to interpret the plan and any
agreement made thereunder, grant awards and make all other determinations to
administer the plan.
 
     The plan provides for the grant of both incentive stock options, or ISOs,
that qualify under Section 422 of the Internal Revenue Code, and nonqualified
stock options or NQSOs. ISOs may be granted only to our employees or employees
of a parent or subsidiary. NQSOs and all other awards other than ISOs may be
granted to our employees, directors and other third parties who render services
to us or any parent or subsidiary that are not in connection with the offer and
sale of securities in a capital-raising transaction. The exercise price of ISOs
must be at least equal to the fair market value of the Common Stock on the date
of grant. The exercise price of NQSOs must be at least equal to 85% of the fair
market value of the Common Stock on the date of grant. Options granted under the
plan have a maximum term of 10 years. Awards granted under the plan may not be
transferred other than by will or by the laws of descent and distribution. They
generally must also be exercised during the lifetime of the optionee only by the
optionee.
 
     Options granted under the plan generally expire three months after the
termination of the optionee's service, except in the case of death or
disability, in which case the options generally may be exercised up to 12 months
following the date of death or termination of service. Options will generally
terminate immediately upon termination for cause. If MarketWatch.com is
dissolved or liquidated or has a "change in control" transaction, outstanding
awards may be assumed or substituted by the successor corporation, if any. If a
successor corporation does not assume or substitute the awards, the Compensation
Committee may accelerate the vesting of the awards prior to the effectiveness of
the transaction.
 
     401(k) Plan. Employees of MarketWatch.com participate in the Data
Broadcasting Corporation 401(k) Profit Sharing Plan, a defined contribution plan
intended to qualify under Section 401 of the Internal Revenue Code. All
personnel who have completed six consecutive months of service with
MarketWatch.com are eligible to participate and may enter the plan as of the
first day of January, April, July or October. Participants may make pre-tax
contributions to the plan of up to 15% of their eligible earnings, subject to a
statutorily prescribed annual limit. MarketWatch.com may make matching
contributions on a discretionary basis to the plan. Each Participant is fully
vested in his or her contributions, any matching contributions, and the
investment earnings thereon. Contributions by the participants or
MarketWatch.com, and the income earned on such contributions, are generally not
taxable to the participants until withdrawn. Contributions by MarketWatch.com,
if any,
 
                                       53
<PAGE>   54
 
are generally deductible by MarketWatch.com when made. Contributions are held in
trust as required by law. Individual participants may direct the trustee to
invest their accounts in authorized investment alternatives. MarketWatch.com
made no matching contributions to the plan as of September 30, 1998.
MarketWatch.com intends to implement its own 401(k) Plan after this offering.
 
INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY
 
     Our Amended and Restated Certificate of Incorporation includes a provision
that eliminates the personal liability of its directors for monetary damages for
breach of fiduciary duty as a director, except for liability:
 
     - for any breach of the director's duty of loyalty to MarketWatch.com or
       its stockholders;
 
     - for acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;
 
     - under the section 174 of the Delaware General Corporation Law regarding
       unlawful dividends and stock purchases; or
 
     - for any transaction from which the director derived an improper personal
       benefit.
 
These provisions are permitted under Delaware law.
 
     Our Bylaws provide that:
 
     - we must indemnify our directors and officers to the fullest extent
       permitted by Delaware law, subject to certain very limited exceptions;
 
     - we may indemnify our other employees and agents to the same extent that
       we indemnified our officers and directors, unless otherwise required by
       law, our Amended and Restated Certificate of Incorporation, our Bylaws or
       agreements; and
 
     - we must advance expenses, as incurred, to our directors and executive
       officers in connection with a legal proceeding to the fullest extent
       permitted by Delaware Law, subject to certain very limited exceptions.
 
     Prior to the completion of this offering, we intend to enter into Indemnity
Agreements with each of our directors and executive officers to give them
additional contractual assurances regarding the scope of the indemnification
described above and to provide additional procedural protections. In addition,
we intend to obtain directors' and officers' insurance providing indemnification
for our directors, officers and certain employees for certain liabilities. We
believe that these indemnification provisions and agreements are necessary to
attract and retain qualified directors and officers.
 
     The limitation of liability and indemnification provisions in our Amended
and Restated Certificate of Incorporation and Bylaws may discourage stockholders
from bringing a lawsuit against directors for breach of their fiduciary duty.
They may also have the effect of reducing the likelihood or derivative
litigation against directors and officers, even though such an action, if
successful, might otherwise benefit us and our stockholders. Furthermore, a
stockholder's investment may be adversely affected to the extent we pay the
costs of settlement and damage awards against directors and officers pursuant to
these indemnification provisions.
 
     At present, there is no pending litigation or proceeding involving any of
our directors, officers or employees regarding which indemnification is sought,
nor are we aware of any threatened litigation that may result in claims for
indemnification.

                              CERTAIN TRANSACTIONS
 
     Since the inception of the Predecessor Business, there has not been, nor is
there currently proposed, any transaction or series of similar transactions to
which we were or will be a party in which the amount involved exceeded or will
exceed $60,000 and in which any director, executive officer, holder of more than
5% of our Common Stock or any member of the immediate family of any of the
foregoing persons had or will have a direct or indirect material interest other
the compensation agreements and other arrangements, which are described where
required in "Management," and the transactions described below. The agreements
described below are included as exhibits to the Registration Statement of which
this Prospectus forms a part.
 
FORMATION TRANSACTIONS
 
     On October 29, 1997, CBS and DBC entered into a limited liability company
agreement and certain related agreements relating to the formation of the LLC.
 
     LIMITED LIABILITY COMPANY AGREEMENT
 
     CBS and DBC entered into a limited liability company agreement (the
"Limited Liability Company Agreement"). Each of CBS and DBC received a 50%
membership interest in the LLC in exchange for entering into the Limited
Liability Company Agreement and for their capital contributions under the
Contribution Agreement described below. DBC also agreed to loan the LLC until
October 2000, up to $5.0 million at an annual interest rate equal to The Chase
Manhattan National Bank's prime rate plus two percent. As of September 30, 1998,
the Company had borrowed approximately $3.0 million from DBC. Interest payments
to DBC during the nine months ended September 30, 1998 were $75,000. The Limited
Liability Company Agreement also contained provisions relating to, among other
things, the management of the LLC, allocations of profits and losses, transfer
restrictions and dispute resolution and covenants not to compete.
 
     CONTRIBUTION AGREEMENT
 
     Contemporaneously with the Limited Liability Company Agreement, CBS, DBC
and the LLC also entered into a Contribution Agreement (the "Contribution
Agreement"). Pursuant to the Contribution Agreement, CBS agreed to provide the
LLC with $50 million aggregate rate card amount advertising and promotion (the
"Advertising Commitment") over a period of five years over the CBS Television
Network, CBS owned and operated television and radio stations or on CBS Internet
sites, provided that no more than 5% of the total advertising could be on CBS
Internet sites. This commitment will be reduced to $30 million pursuant to the
Stockholders' Agreement. CBS exercised, and still holds, substantial control
over the allocation of the Advertising Commitment. DBC contributed to the LLC
all of its right, title and interest in certain assets relating to Online/ News
business as well as $1.0 million in cash. DBC also agreed to contribute an
additional $1.0 million to the LLC in October 1998. This additional contribution
was made on October 28, 1998.
 
     ORIGINAL SERVICES AGREEMENT
 
     Contemporaneously with the Limited Liability Company Agreement, DBC and the
LLC also entered into a Services Agreement, which we refer to as the "Original
Services Agreement," under which DBC provided us with a variety of support and
hosting services. Payments by the Company to DBC for these Services were $70,000
and $517,000 in 1997 and the nine months ended September 30, 1998, respectively.
DBC also agreed to pay MarketWatch.com a per subscriber fee for users of DBC's
PC-based and Quotrek subscribers of real-time quotes (the "Subscriber Payment").
Subscriber Payments to us by DBC under the Original Services Agreement were
$210,000 and $949,000 in 1997 and the nine months ended September 30, 1998,
respectively. From October 1997 through May 1998, DBC also provided us with
office space for our executive offices for no charge. DBC also pays us a fee
based upon net revenues from subscriptions to MarketWatch RT and MarketWatch
LIVE (the "Real-Time Fees"). DBC paid us $16,000 and $117,000 in 1997 and the
 
                                       55

nine months ended September 30, 1998, respectively, as Real-Time Fees. This
agreement will be superseded and replaced by the Amended and Restated Services
Agreement described below.
 
     ORIGINAL LICENSE AGREEMENT
 
     Contemporaneously with the Limited Liability Company Agreement, CBS and the
LLC also entered into a License Agreement (the "Original License Agreement").
Under this agreement CBS granted the LLC a non-exclusive license to utilize the
CBS marks "CBS(R)" and the CBS "eye" design for use in connection with the
operation of the MarketWatch.com site. CBS also granted the LLC a license to use
current CBS Television News content related to business and financial news on
the MarketWatch.com site, excluding sponsorships. The LLC paid CBS a royalty
based on amounts received for advertising on the CBS.MarketWatch.com site. There
were no payments to CBS under the Original License Agreement in 1997. We accrued
$148,000 under the Original License Agreement for the nine months ended
September 30, 1998, respectively. This agreement was superseded and replaced by
the Amended and Restated License Agreement described below.
 
REORGANIZATION TRANSACTIONS
 
     CONVERSION OF LLC
 
     MarketWatch.com converted its business form to a corporation in order to
have a business organization form that is more typical of other publicly-traded
entities in our market. The Reorganization was effected by merging the LLC into
MarketWatch.com. In connection with the Reorganization, the Limited Liability
Company Agreement will terminate, except for certain covenants that, by their
terms, require performance after the termination of such agreement, and each of
DBC and CBS will receive 4,500,000 shares of Common Stock in exchange for their
membership interests in the LLC. Additionally, all outstanding options to
purchase membership interests in the LLC were converted into options to purchase
Common Stock.
 
     AMENDED AND RESTATED LICENSE AGREEMENT
 
     We entered into an Amended and Restated License Agreement with CBS which
supersedes and replaces the Original License Agreement.
 
     Reasons for Amending and Restating the License. MarketWatch.com, CBS and
DBC agreed to amend the terms of the Original License Agreement because the
parties believed its terms would be appropriate only if the LLC remained as a
private limited liability company owned equally by CBS and DBC, with no outside
investors. As part of the conversion of the LLC to a corporation, the terms of
the Original License Agreement were amended to help make the business attractive
to outside investors. For example, MarketWatch.com believed that the royalty
equal to 30% of advertising revenues could adversely affect gross margins,
particularly if MarketWatch.com received a substantial portion of its revenues
from non-sponsorship advertising. As part of the agreement to modify the royalty
rate, other terms of the relationship with CBS were amended, including extending
the term of the license, modifying the amount of the CBS advertising commitment,
and the non-competition provisions.
 
     Term. The term of the Amended Restated License Agreement will expire on
October 29, 2005.
 
     Royalties. Under the Amended and Restated License Agreement, we will pay
CBS:
 
        During 1998:
 
        - 8% of Gross Revenues in excess of $1.0 million and up to and including
          $51.0 million; and
 
        - 6% of Gross Revenues in excess of $51.0 million.
 
        During 1999:
 
        - 8% of Gross Revenues in excess of $500,000 and up to and including
          $50.5 million; and
 
                                       56
<PAGE>   57
 
        - 6% of Gross Revenues in excess of $50.5 million.
 
        In subsequent years through October 29, 2005:
 
        - 8% of Gross Revenues up to and including $50.0 million; and
 
        - 6% of Gross Revenues in excess of $50.0 million.
 
     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 Revenue 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. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
     Control of Content by CBS. Under the Amended and Restated License
Agreement, CBS will retain significant editorial control over the use and
presentation of CBS television news content and the CBS logo. For example:
 
     - we must conform to CBS's guidelines for the use of its trademarks;
 
     - CBS has the right to approve all materials, such as marketing materials,
       which include any CBS trademarks; and
 
     - CBS has control over the visual and editorial presentation of its
       television news content on the CBS.MarketWatch.com Web site.
 
     As a result of these provisions, CBS will have the ability to prevent us
from displaying certain types of content on the CBS.MarketWatch.com Web site and
from producing materials, such as marketing materials, which it does not
approve. This control by CBS could prevent us from engaging in desired marketing
activities or from being perceived as an independent news organization, either
of which could adversely affect our brand awareness and brand name.
 
     Termination if CBS Competitors Acquire Our Securities. CBS will be able to
terminate our right to use the CBS name, logo and news content in the event
that:
 
     - a competitor of CBS directly or indirectly beneficially owns 15% or more
       of our outstanding Common Stock or voting power of MarketWatch.com; or
 
     - if we issue to a CBS competitor or actively participate in the
       acquisition by a CBS competitor a number of voting securities, such that
       after the issuance(s), such CBS competitor beneficially owns 9% or more
       of our voting securities.
 
     Notwithstanding the foregoing, the mere acquisition by a CBS competitor of
an interest in DBC that causes a DBC Change of Control shall not be deemed to
constitute the acquisition of an ownership interest in MarketWatch.com in the
absence of other facts demonstrating ownership of an interest in
MarketWatch.com.
 
     Other Grounds for Termination. The Amended and Restated License Agreement
will also be subject to termination if we:
 
     - breach a material term or condition of the Amended and Restated License
       Agreement;
 
     - become insolvent or subject to bankruptcy or similar proceedings; or
 
     - discontinue using the MarketWatch mark and does not establish a
       substitute mark acceptable to CBS in its sole discretion.
 
     Non-Competition Provisions. Under the terms of the Amended and Restated
License Agreement, CBS will not be permitted to license or authorize another to
license the use of the CBS logo or name to others in connection with promoting
any other Internet Service or Web site in the U.S. that
                                       57
<PAGE>   58
 
has 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, which we refer to as a "Business Site." The
following activities would not be prohibited:
 
     - licensing its logo or name to a Web site or Internet service that
       delivers general news, sports or entertainment, with a financial news
       segment or portion included;
 
     - licensing its name or logo to a Web site or Internet service outside the
       U.S.;
 
     - licensing its name or logo to Web sites that provide stock price ticker
       displays on the site;
 
     - any activity conducted by CBS and/or its affiliates prior to CBS's
       signing the Amended and Restated License Agreement;
 
     - any activities of non-CBS owned television and radio station affiliates;
 
     - any Internet services in which CBS has an interest prior to signing the
       Amended and Restated License Agreement;
 
     - any activity of Westwood One, Inc. if such activity does not produce a
       substantial portion of its revenues from a Business Site; or
 
     - any transmissions of any signal of any type by and if through CBS's cable
       television operations.
 
     As a result, if CBS were to license its name and logo to another Web site
or Internet service that delivers general news, sports or entertainment and that
also delivers financial news, such other Web site or service could be
competitive with our Web site.
 
     Also, CBS will not be prohibited from licensing its news content to, or
investing in, another Web site or Internet service, regardless of the theme of
that Web site or Internet service. See "Risk Factors -- Risks Related to Our
Relationship with CBS and DBC -- Potential Competition from CBS and DBC."
 
     AMENDED AND RESTATED SERVICES AGREEMENT
 
     DBC and MarketWatch.com entered into an Amended and Restated Services
Agreement which supersedes and replaces the Original Services Agreement.
 
     Reasons for Amending the Services Agreement. MarketWatch.com, CBS and DBC
agreed to amend the terms of the Original Services Agreement to extend the term,
provide for agreed upon network performance standards, grant non-exclusive
licenses to use DBC's trademark and data feeds and to document other changes in
our relationship with DBC which were not previously memorialized so that
MarketWatch.com could operate the Web site when it became an independent entity.
There were no material changes to the economic terms of the Original Services
Agreement.
 
     Services Provided. Under the Amended and Restated Services Agreement, DBC
will, upon request:
 
     - provide us with any employees needed to operate our business;
 
     - handle billing and collections for our subscription products;
 
     - provide computer programming and engineering services;
 
     - provide delayed commodities and stock data feeds as well as certain other
       data feeds free of charge; and
 
     - provide communications Web site hosting services pursuant to certain
       performance standards.
 
     These services will be provided at DBC's out-of-pocket cost. DBC will also
continue to pay MarketWatch.com the Subscriber Payments except with respect to
certain of DBC's commercial subscribers. The term of the Amended and Restated
Services Agreement will expire on October 29, 2005. However, DBC's Subscriber
Payments obligation will expire in October 2002.
 
     Currently, DBC does not provide similar services to any other third party.
 
                                       58
<PAGE>   59
 
     Non-Competition Provisions. The Amended and Restated Services Agreement
does not contain any exclusivity provisions or non-competition provisions. For
example, DBC could:
 
     - provide Web sites hosting services to other Web sites;
 
     - provide content or data to other Web sites including MarketWatch RT and
       MarketWatch Live; or
 
     - sell its services through other Web sites.
 
     CREDIT AGREEMENT
 
     MarketWatch.com and DBC entered into a Revolving Credit Agreement (the
"Credit Agreement") in order to evidence DBC's loan obligation under the Limited
Liability Company Agreement. Under the Credit Agreement, DBC will be obligated
to loan MarketWatch.com up to $5.0 million through October 2000. Borrowings
under the Credit Agreement will be unsecured and bear interest at a rate equal
to The Chase Manhattan National Bank's prime rate plus two percent per annum and
mature on October 29, 2000. MarketWatch.com's previous borrowings from DBC will
be included as indebtedness outstanding under the Credit Agreement. As of
September 30, 1998, MarketWatch.com had outstanding indebtedness to DBC of
$3,028,000.
 
     STOCKHOLDERS' AGREEMENT
 
     DBC, CBS and MarketWatch.com entered into a Stockholders' Agreement (the
"Stockholders' Agreement").
 
     CBS Advertising Commitment. The parties agreed to reduce the Advertising
Commitment provided for in the Contribution Agreement to an aggregate rate card
amount of $30 million during the period from October 29, 1997 through October
29, 2002 in return for a reduction in the percentage royalty to be paid to CBS
under the License Agreement. As of September 30, 1998, CBS had delivered $5.0
million rate card amount of advertising and promotion to us. This Advertising
Commitment is subject to termination upon termination of the Amended and
Restated License Agreement, in which event, CBS shall make a termination payment
in the amount of $500,000 per month for each full calendar month remaining from
the termination through October 2002.
 
     Board Members. The Stockholders' Agreement also provides that each of CBS
and DBC will be entitled to nominate up to three members to our Board of
Directors, so long as it holds at 30%, two, so long as it holds at least 20% but
less than 30%, or one, so long as it holds at least 1%, of our outstanding
voting securities. So long as the Amended and Restated License Agreement is in
effect, CBS shall have the right to appoint at least one member to our Board of
Directors, regardless of its percentage ownership of our Common Stock. If the
size of the Board of Directors is increased, CBS and DBC will each have the
right to nominate a number of candidates to the Board of Directors based upon
the percentage of our outstanding voting securities then held by them.
 
     Right of First Refusal. Pursuant to the Stockholders' Agreement, each of
CBS and DBC will have a right of first refusal in the event that either party
desires to sell any securities of the Company held by it to a third party. In
addition, each of CBS and DBC will have the right to purchase from us additional
shares of our Common Stock, other of our voting securities or securities
convertible into or exchangeable for such securities, which we call New
Securities, if we propose to issue New Securities. In such a case, they would be
able to purchase an amount, subject to certain limitations, necessary to
maintain its then current percentage ownership, not to exceed the party's
percentage ownership interest immediately after the closing of this offering.
See "Description of Capital Stock -- Rights of First Refusal."
 
     Non Competition Provisions for DBC. DBC agreed, inter alia, that until
October 29, 2005 and subject to certain exceptions:
 
     - it will not, nor will it authorize or permit another to, sell advertising
       on any other Web site that has as its primary function and its principal
       theme and format the delivering of comprehensive real-time or delayed
       stock quotations and financial news in the English language to consumers;
       or
 
                                       59
<PAGE>   60
 
     - it will not use the Internet to sell real-time stock-quotes in "snapshot"
       form.
 
     Therefore, DBC would be permitted to:
 
     - sell advertising on a general news, sports or entertainment Web site with
       a financial news segment;
 
     - provide data or content to any other Web site, regardless of its theme so
       long as it was not selling data and content that was real-time
       snap-quotes;
 
     - host any other Web site; or
 
     - invest in any other Web site so long as it held less than 5% of any stock
       or less than 10% of the indebtedness of that company.
 
     If DBC did any of these, our business could be adversely affected. See
"Risk Factors -- Risks Related to Our Relationship with CBS and DBC -- Potential
Competition from CBS and DBC."
 
     Our Non Competition Obligations. In addition, we will agree not, except
through DBC, to sell any product or service that offers streaming real-time
stock price quotes. This obligation expires on October 29, 2005 or, at such
earlier time:
 
     - as the Amended and Restated Services Agreement has terminated;
 
     - upon the occurrence of a DBC Change of Control; or
 
     - at such time as DBC shall hold less than 10% of our then-outstanding
       voting securities.
 
     REGISTRATION RIGHTS AGREEMENT
 
     CBS and DBC will have certain registration rights with respect to their
shares of Common Stock. See "Description of Capital Stock -- Registration
Rights."
 
OTHER RELATIONSHIPS WITH DBC
 
     Pursuant to an August 1998 Insertion Order Form, DBC has agreed to purchase
approximately $225,000 of advertising from the Company in 1998 and approximately
$500,000 of advertising from the Company in each of 1999 and 2000. This
commitment may be terminated by DBC on 30 days' notice.
 
EMPLOYMENT RELATED AGREEMENTS
 
     In October 1997, we granted Mr. Kramer an option to purchase 200,000 shares
of Common Stock at an exercise price of $4.00 per share. This option vests as to
one-third of the shares subject to the option on each anniversary of its date of
grant. We also entered into an employment agreement with Mr. Kramer effective
July 1, 1998. Mr. Kramer's employment agreement provides for a base salary of
$210,000 from the effective date through June 30, 1999, $225,000 through June
30, 2000, and $240,000 through June 30, 2001. Mr. Kramer is also eligible to
receive an annual bonus of up to 50% of his annual base salary. The employment
agreement has a term of three years.
 
     In July 1998, Mr. Bardwick was granted an option to purchase 100,000 shares
of Common Stock at an exercise price of $4.00 per share. This option vests as to
one-third of the shares subject to the option on each anniversary of Mr.
Bardwick's employment start date. We also entered into an employment agreement
with Mr. Bardwick effective July 1, 1998. Mr. Bardwick's employment agreement
provides for a base salary of $200,000 from the effective date through June 30,
1999, $210,000 through June 30, 2000, and $225,000 through June 30, 2001. Mr.
Bardwick is also eligible to receive an annual bonus of up to 50% of his annual
base salary. The employment agreement has a term of three years.
 
     If Mr. Kramer or Mr. Bardwick's employment is terminated or if he resigns
because of a constructive termination, he will be entitled to receive:
 
     - an amount equal to his then current base salary, payable in twelve
       monthly installments; and
 
     - his stock options will vest as to an additional one-third of the shares
       subject to the option.
 
                                       60
<PAGE>   61
 
     A constructive termination means:
 
     - a material change of position causing it to be of materially less stature
       or responsibility;
 
     - a salary reduction of more than 10%; or
 
     - relocating his place of employment outside the San Francisco Bay Area.
 
     If his employment is terminated without cause or if he resigns because of a
constructive termination within six months of a change of control, he will be
entitled to receive:
 
     - a lump sum payment in the amount of his current base salary plus his
       target bonus for the current year; and
 
     - his options will vest as to an additional one-third of the shares subject
       to the option.
 
     A change of control means:
 
        - the sale of substantially all of our assets to an entity other than
          CBS or DBC; or
 
        - any transaction or series of transactions that results in any person
          other than CBS, DBC or other affiliated entities with us, owning more
          than 50% of our voting power.
 
     This lump sum would equal $315,000 based on Mr. Kramer's current base
salary and $300,000 based on Mr. Bardwick's current base salary.
 
     Ms. Chaboudy's employment offer letter of April 23, 1998 provides for an
initial annual base salary of $100,000. Ms. Chaboudy was also granted an option
to purchase 50,000 shares of Common Stock at an exercise price of $11.00 per
share. This option vests as to one-third of the shares subject to the option on
each anniversary of Ms. Chaboudy's employment start date.
 
     Mr. McLernon's employment offer letter dated December 30, 1997 provided for
an initial base salary of $95,000. In addition, Mr. McLernon is entitled to
receive a commission in 1998 and 1999 in the amount of 3% of our advertising and
sponsorship sales and the Company has agreed to reimburse Mr. McLernon's
expenses, up to $15,000 per year, for working in San Francisco, California. We
agreed to renegotiate his compensation terms at the end of 1999 based on market
conditions and our operating projections. Mr. McLernon was also granted an
option to purchase 75,000 shares of Common Stock at a purchase price of $8.00.
This option vests as to one-third of the shares subject to the option on each
anniversary of Mr. McLernon's employment start date.
 
     Mr. Calandra, our Vice President of News, receives an annual base salary of
$100,000 and in October 1997, received a grant of an option to purchase 75,000
shares of Common Stock at a purchase price of $4.00 per share. This option vests
as to one-third of the shares subject to the option on each anniversary of its
date of grant.
 
OFFICE LEASE
 
     Since April 1, 1998, we occupied space in a CBS facility to house its
headquarters in San Francisco, California. We paid CBS a monthly rent of
approximately $6,000 for this space prior to September 1, 1998 for approximately
4,500 square feet. On August 27, 1998, we entered into a lease with CBS with
respect to an additional 7,000 square feet of space at the same facility and
this lease will expire in March 2003. We are obligated to pay monthly rent of
approximately $26,000 in the aggregate through the expiration date. We are also
obligated to pay its proportionate share of all electricity, heating,
ventilation and air conditioning costs for the leased premises.
 
     We believe that the terms of each of the transactions described above,
taken as a whole, were no less favorable than we could have obtained from
unaffiliated third parties. All future transactions with our officers, directors
and principal stockholders and their affiliates will be approved by a majority
of the Board of Directors, including a majority of the independent and
disinterested outside directors.

                          DESCRIPTION OF CAPITAL STOCK
 
     Our authorized capital stock consists of 30,000,000 shares of Common Stock,
$0.01 par value per share, and 5,000,000 shares of Preferred Stock, $0.01 par
value per share. As of November 30, 1998, assuming the conversion of our
business form into a corporation, and the simultaneous conversion of limited
liability company membership interests into shares of Common Stock, there were
outstanding 9,000,000 shares of Common Stock, each with a par value of $0.01,
held of record by two stockholders, and outstanding options to purchase 947,250
shares of Common Stock.
 
     MarketWatch.com's Amended and Restated Certificate of Incorporation,
Bylaws, the Stockholders' Agreement and the Registration Rights Agreement
described below are included as exhibits to the Registration Statement of which
this Prospectus forms a part.
 
COMMON STOCK
 
     Subject to preferences that may be applicable to any Preferred Stock
outstanding at the time, the holders of outstanding shares of Common Stock are
entitled to receive dividends out of assets legally available therefor at such
times and in such amounts as the Board from time to time may determine. Holders
of Common Stock are entitled to one vote for each share held on all matters
submitted to a vote of shareholders. Cumulative voting for the election of
directors is not authorized by MarketWatch.com's Certificate of Incorporation,
which means that the holders of a majority of the shares voted can elect all of
the directors then standing for election. The Common Stock is not entitled to
preemptive rights and is not subject to conversion or redemption. Upon
liquidation, dissolution or winding-up of, the assets legally available for
distribution to stockholders distributable ratably among the holders of the
Common Stock after payment of liquidation preferences, if any, on any
outstanding Preferred Stock and payment of other claims of creditors. Each
outstanding share of Common Stock is, and all shares of Common Stock to be
outstanding upon completion of this offering will be upon payment therefor, duly
and validly issued, fully paid and nonassessable.
 
PREFERRED STOCK
 
     The Board is authorized, subject to any limitations prescribed by Delaware
law, to issue Preferred Stock in one or more series. The Board can fix the
rights, preferences and privileges of the shares of each series and any
qualifications, limitations or restrictions thereon.
 
     The Board may authorize the issuance of Preferred Stock with voting or
conversion rights that could adversely affect the voting power or other rights
of the holders of Common Stock. The issuance of Preferred Stock, while providing
flexibility in connection with possible acquisitions and other corporate
purposes could, among other things, under certain circumstances, have the effect
of delaying, deferring or preventing a change in control of MarketWatch.com. We
have no current plan to issue any shares of Preferred Stock.
 
REGISTRATION RIGHTS
 
     We entered into a Registration Rights Agreement with CBS and DBC prior to
the closing of this offering. At any time after 180 days following the date of
this Prospectus, either of these companies may demand that we file a
registration statement under the Securities Act covering all or a portion of the
securities of MarketWatch.com held by either of them, their affiliates and their
permitted transferees. However, the securities to be registered must have a
reasonably anticipated aggregate public offering price of at least $3.0 million.
CBS and DBC can each effect two such demand registrations.
 
     When we are eligible to utilize a Registration Statement on Form S-3 to
register an offering of our securities, CBS and DBC may request that we file a
registration statement on Form S-3, covering all or a portion of securities of
MarketWatch.com held by either of CBS, DBC, their affiliates and
 
                                       63
<PAGE>   64
 
their permitted transferees, provided that the aggregate public offering price
is at least $1.0 million (a "S-3 Registration"). CBS and DBC each can request
one S-3 Registration per year.
 
     These registration rights will be subject to the Company's right to delay
the filing of a registration statement in certain circumstances, not more than
once in any 12-month period, for not more than 120 days.
 
     In addition, CBS and DBC will have certain "piggyback" registration rights.
If we propose to register any Common Stock under the Securities Act, other than
pursuant to the registration rights noted above, CBS and DBC may require us to
include all or a portion of their securities in such registration. However, the
managing underwriter, if any, of any such offering has certain rights to limit
the number of Registrable Securities proposed to be included in such
registration.
 
     We would bear all registration expenses incurred in connection with these
registrations. Each of CBS and DBC would pay all underwriting discounts, selling
commissions and stock transfer taxes applicable to the sale of its securities.
 
     The registration rights of CBS or DBC under the Registration Rights
Agreement will terminate when that company may sell all its shares in a
three-month period under Rule 144 promulgated under the Securities Act.
 
DBC CHANGE OF CONTROL
 
     Under the terms of the Stockholders' Agreement, upon the occurrence of a
DBC Change of Control, CBS may, in its sole discretion within 45 days after
receipt of written notice of the occurrence of such DBC Change of Control,
either:
 
     - purchase all of the MarketWatch.com securities held by DBC at the "fair
       market value" of the securities as of the date of the DBC Change of
       Control; or
 
     - require DBC, within 60 days, to place its securities in a trust managed
       by an independent trustee reasonably satisfactory to CBS, which would
       then dispose of the securities to persons who are not competitors of CBS
       with a view to maximizing the sale price while disposing of such share as
       promptly as reasonably practicable.
 
     In either event, DBC would forfeit its Board representation. No such
trustee shall vote any of the securities held by it without the prior written
consent of CBS. Any sales by such a trustee could have an adverse effect on the
market price of the Common Stock. There can be no assurance that after a DBC
Change of Control CBS would elect either such option, if any.
 
     A "DBC Change of Control" means the direct or indirect acquisition by a
competitor of CBS of:
 
     - more than 30% of the outstanding Common Stock or securities representing
       30% of the voting power of DBC; or
 
     - substantially all of DBC's assets
 
in each case at a time when DBC or its affiliates own a number of shares of
Common Stock equal to or greater than 10% of the Common Stock outstanding
immediately after this offering.
 
     Although DBC has advised us that it has no present plans or intentions to
effect a DBC Change of Control, DBC operates in a rapidly evolving industry and
there can be no assurance that it will not effect a change in control in the
future.
 
RIGHTS OF FIRST REFUSAL
 
     If either CBS or DBC desires to sell any shares held by it to a
non-affiliated third party, the other party will have a right of first refusal
under the Stockholders' Agreement to purchase those shares from the other, on
the same terms as the party proposes to sell the shares to the third party. In
the event that the other party does not exercise this right of first refusal,
the party who originally
                                       64
<PAGE>   65
 
proposed to transfer the shares will have 120 days or, in the case of a sale
pursuant to Rule 144 promulgated under the Securities Act, six weeks to
consummate the transfer, otherwise the rights of first refusal will be
reinstated.
 
     The Stockholders' Agreement also provides that in the event that we propose
to issue voting securities or securities convertible into or exchangeable for
Common Stock or other voting securities in the future, CBS and DBC will have the
right to purchase a number of securities from us on the same terms in an amount
necessary to maintain its percentage ownership of voting securities, not to
exceed a percentage equal to the percentage of the outstanding voting securities
held by such company upon the consummation of this offering (the "Initial
Percentage"). If we receive non-cash consideration for an issuance, the purchase
price for CBS and DBC will be a per share price equal to the "fair market value"
of the non-cash consideration.
 
     This purchase right will not apply to issuances by MarketWatch.com of up
to:
 
        - 1,500,000 shares in connection with incentive plans or employee stock
          options; or
 
        - 500,000 shares issuable for general corporate purposes.
 
     If in the opinion of the underwriters of our first public offering
following this offering, the public trading market for our Common Stock would be
significantly adversely affected by the exercise of this purchase right, CBS and
DBC have the right to exercise the purchase right in connection with that
offering only to the extent required to maintain ownership of up to 25% of the
outstanding voting securities. The underwriters of that offering could allow a
higher percentage, if in their opinion that higher percentage would not,
significantly adversely affect such offering. Each of CBS and DBC would then
have the right in connection with the next issuance to exercise the purchase
right to purchase a number of additional securities in an amount necessary to
maintain its percentage ownership of the voting securities of it held
immediately prior to that public offering, not to exceed a percentage of the
outstanding voting securities of the Company equal to the Initial Percentage.
 
     In addition, as a result of the purchase right and right of first refusal,
both CBS and DBC will have the ability to maintain collectively, ownership in
excess of 50% of our outstanding Common Stock; however, neither CBS nor DBC are
obligated to vote their shares in any manner, other than to vote for each
other's nominees to the Board of Directors or otherwise act collectively. These
rights could have the effect of delaying, deferring or preventing a change in
control of MarketWatch.com or to discourage bids for our Common Stock at a
premium over its market price.
 
DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER AND BYLAW PROVISIONS
 
     We are subject to the provisions of Section 203 of the Delaware General
Corporation Law regulating corporate takeovers. This section prevents certain
Delaware corporations, from engaging, under certain circumstances, in a
"business combination," which includes a merger or sale of more than 10% of the
corporation's assets, with any "interested stockholder," or a stockholder who
owns 15% or more of the corporation's outstanding voting stock, as well as
affiliates and associates of any such persons, for three years following the
date that such stockholder became an "interested stockholder" unless:
 
     - The transaction in which such stockholder became an "interested
       stockholder" is approved by the Board of Directors prior to the date the
       "interested stockholder" attained such status;
 
     - upon consummation of the transaction that resulted in the stockholder's
       becoming an "interested stockholder," the "interested stockholder" owned
       at least 85% of the voting stock of the corporation outstanding at the
       time the transaction commenced -- excluding those shares owned by persons
       who are directors and also officers; or
 
     - on or subsequent to such date the "business combination" is approved by
       the Board of Directors and authorized at an annual or special meeting of
       stockholders by the affirmative
                                       65
<PAGE>   66
 
       vote of at least two-thirds of the outstanding voting stock that is not
       owned by the "interested stockholder."
 
     Neither CBS nor DBC are subject to the restrictions imposed by this
statute. This statute could prohibit or delay mergers or other takeover or
change-in-control attempts with respect to MarketWatch.com and, accordingly, may
discourage attempts to acquire us.
 
     Our Bylaws provide that any action required or permitted to be taken by our
stockholders at an annual meeting or special meeting may only be taken if it is
properly brought before such meeting. The Amended and Restated Certificate of
Incorporation and the Bylaws provide that special meetings of the stockholders
may only be called by the Chairman of the Board, the Chief Executive Officer,
the Board or by any stockholder holding at least 25% of the outstanding Common
Stock. Such provisions may have the effect of delaying or preventing a
change-in-control.
 
LIMITATIONS ON LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
     Our Amended and Restated Certificate of Incorporation limits the liability
of directors to the fullest extent permitted by Delaware law. In addition, our
Amended and Restated Certificate of Incorporation and Bylaws provide that we
will indemnify directors and officers of the Company to the fullest extent
permitted by Delaware law. We intend to enter into separate indemnification
agreements with our directors and executive officers that provide such person
indemnification protection in the event the Amended and Restated Certificate of
Incorporation is subsequently amended.
 
     Our Amended and Restated Certificate of Incorporation and Bylaws provide
that we will indemnify officers and directors against losses that they may incur
in investigations and legal proceedings resulting from their services to the
Company, which may include services in connection with takeover defense
measures. Such provisions may have the effect of preventing changes in the
management.

Shareholder Services, L.L.C. Its address is 235 Montgomery Street, 23rd Floor,

<PAGE>   67
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial amounts of our Common Stock in the public market could
adversely affect prevailing market prices of our Common Stock. Furthermore,
since no shares will be available for sale shortly after this offering because
of certain contractual and legal restrictions on resale described below, sales
of substantial amounts of Common Stock in the public market after these
restrictions lapse could adversely affect the prevailing market price and our
ability to raise equity capital in the future.
 
     Upon completion of this offering, we will have outstanding an aggregate of
11,275,000 shares of our Common Stock, assuming no exercise of the Underwriters'
over-allotment option and no exercise of outstanding options. Of these shares,
all of the shares sold in this offering will be freely tradable without
restriction or further registration under the Securities Act, unless such shares
are purchased by "affiliates" as that term is defined in Rule 144 under the
Securities Act (the "Affiliates"). The remaining 9,000,000 shares of Common
Stock held by existing stockholders are "restricted securities" as that term is
defined in Rule 144 under the Securities Act. Restricted securities may be sold
in the public market only if registered or if they qualify for an exemption from
registration under Rule 144 or 701 promulgated under the Securities Act, which
rules are summarized below.
 
     As a result of the contractual restrictions described below and the
provisions of Rule 144 and 701, the restricted securities will be available for
sale in the public market on the date which is one year from the date of the
effectiveness of the Reorganization, subject to the volume limitations and other
conditions of Rule 144. The shares could be available for resale immediately
upon the expiration of such 180-day period in the event of a favorable
interpretation by the Securities and Exchange Commission of certain provisions
of Rule 144.
 
  Lock-Up Agreements
 
     All of our officers, directors and stockholders have signed Lock-Up
Agreements under which they agreed not to transfer or dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for shares of Common Stock, for a period of 180 days
after the date of this Prospectus. Transfers or dispositions can be made sooner:
 
     - with the prior written consent of BT Alex. Brown and Donaldson, Lufkin &
       Jenrette Securities Corporation; or
 
     - in the case of certain transfers upon a DBC Change of Control as provided
       in the Stockholders' Agreement.
 
  Rule 144
 
     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person who has beneficially owned shares of our
Common Stock for at least one year would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of:
 
     - 1% of the number of shares of Common Stock then outstanding, which will
       equal approximately 112,750 shares immediately after this offering; or
 
     - the average weekly trading volume of the Common Stock on the Nasdaq
       National Market during the four calendar weeks preceding the filing of a
       notice on Form 144 with respect to such sale.
 
     Sales under Rule 144 are also subject to certain manner of sale provisions
and notice requirements and to the availability of current public information
about us.
 
                                       67
<PAGE>   68
 
  Rule 144(k)
 
     Under Rule 144(k), a person who is not deemed to have been one of our
Affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an Affiliate, is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144. Therefore,
unless otherwise restricted, "144(k) shares" may be sold immediately upon the
completion of this offering.
 
  Rule 701
 
     In general, under Rule 701 of the Securities Act as currently in effect,
any of our employees, consultants or advisors who purchases shares from us in
connection with a compensatory stock or option plan or other written agreement
is eligible to resell such shares 90 days after the effective date of this
offering in reliance on Rule 144, but without compliance with certain
restrictions, including the holding period, contained in Rule 144.
 
  Registration Rights
 
     Upon completion of this offering, the holders of 9,000,000 shares of our
Common Stock, or their transferees, will be entitled to certain rights with
respect to the registration of such shares under the Securities Act. See
"Description of Capital Stock -- Registration Rights." After such a
registration, these shares becoming freely tradable without restriction under
the Securities Act. Neither CBS nor DBC will have any obligation or other
restrictions on resale with respect to any of our securities, other than
restrictions imposed by Lock-Up Agreements described above, the Right of First
Refusal and applicable securities laws. Any sales of securities by these
stockholders could have a material adverse effect on the trading price of our
Common Stock.
 
  Stock Options
 
     Immediately after this offering, we intend to file a registration statement
under the Securities Act covering 1,500,000 shares of Common Stock reserved for
issuance under our 1998 Equity Incentive Plan and the Directors Stock Option
Plan and the shares reserved for issuance upon exercise of outstanding non-plan
options. As of November 30, 1998, options to purchase 863,500 shares of Common
Stock were issued and outstanding. Upon the expiration of the Lock-Up Agreements
describe above, at least 233,237 shares of Common Stock will be subject to
vested options (based on options outstanding as of November 30, 1998). Such
registration statement is expected to be filed and become effective as soon as
practicable after the effective date of this offering. Accordingly, shares
registered under such registration statement will, subject to vesting provisions
and Rule 144 volume limitations applicable to our Affiliates, be available for
sale in the open market immediately after the 180-day Lock-Up Agreements expire.

     The underwriting agreement provides that the obligations of the several
Underwriters to purchase the shares of Common Stock offered hereby are subject
to certain conditions. The Underwriters are obligated to purchase all of the
shares of Common Stock offered hereby, other than those covered by the
overallotment option described below, if any of such shares are purchased.
 
     The Underwriters propose to offer the shares of Common Stock to the public
at the public offering price set forth on the cover page of this Prospectus and
to certain dealers at a price that represents a concession not in excess of
$0.71 per share under the public offering price. The Underwriters may allow, and
such dealers may re-allow, a concession not in excess of $0.10 per share to
certain other dealers. After the initial public offering, the offering price and
other selling terms may be changed by the representatives of the Underwriters.
 
     An electronic prospectus is available on the Web sites maintained by
DLJdirect Inc., a selected dealer and an affiliate of Donaldson, Lufkin &
Jenrette Securities Corporation, and Wit Capital Corporation, acting as
e-Manager(TM). The Underwriters have agreed to allocate a limited number of
shares to these underwriters for sale to their brokerage account holders. The
information on such Web sites relating to the MarketWatch.com offering is filed
as an exhibit to the Registration
 
                                       69
<PAGE>   70
 
Statement. Reference is made to the exhibit for a more complete description of
the information relating to the MarketWatch.com offering contained on such Web
sites.
 
     MarketWatch.com has granted to the Underwriters an option, exercisable not
later than 30 days after the date of this Prospectus, to purchase up to 412,500
additional shares of Common Stock at the public offering price less the
underwriting discounts and commissions set forth on the cover page of this
Prospectus. The Underwriters may exercise such option only to cover
over-allotments made in connection with the sale of the Common Stock offered
hereby. To the extent that the Underwriters exercise such option, each of the
Underwriters will become obligated, subject to certain conditions, to purchase
approximately the same percentage of additional shares of Common Stock as the
number of shares of Common Stock to be purchased by it in the above table bears
to 2,750,000. MarketWatch.com will be obligated, pursuant to the option, to sell
such shares to the Underwriters to the extent the option is exercised. If any
additional shares of Common Stock are purchased, the Underwriters will offer
additional shares on the same terms as those on which the shares are being
offered.
 
     MarketWatch.com has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act.
 
     Each of MarketWatch.com's officers, directors and stockholders has agreed
not to offer, sell, contract to sell or otherwise dispose of, or enter into any
transaction which is designed to, or could be expected to, result in the
disposition of any portion of, any Common Stock for a period of 180 days after
the effective date of the registration statement of which this Prospectus is a
part without the prior written consent of BT Alex. Brown Incorporated and
Donaldson, Lufkin & Jenrette Securities Corporation. Such consent may be given
at any time without public notice. MarketWatch.com has entered into a similar
agreement, except that we may issue, and grant options or warrants to purchase,
shares of Common Stock or any securities convertible into, exercisable for or
exchangeable for shares of Common Stock, pursuant to the exercise of outstanding
options and warrants and our issuance of options and stock granted under the
existing stock option and stock purchase plans. The restrictions described in
this paragraph do not apply to certain transfers of shares of Common Stock upon
a DBC Change of Control as provided in the Stockholders' Agreement.
 
     The representatives of the Underwriters have advised MarketWatch.com that
the Underwriters do not intend to confirm sales to any account over which they
exercise discretionary authority.
 
     In order to facilitate the offering of the Common Stock, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
market price of the Common Stock. Specifically, the Underwriters may over-allot
shares of the Common Stock in connection with this offering, thereby creating a
short position in the Common Stock for their own account. Additionally, to cover
such over-allotments or to stabilize the market price of the Common Stock, the
Underwriters may bid for, and purchase, shares of the Common Stock in the open
market. Finally, the representatives, on behalf of the Underwriters, also may
reclaim selling concessions allowed to an Underwriter or dealer if the
underwriting syndicate repurchases shares distributed by that Underwriter or
dealer. Any of these activities may maintain the market price of our Common
Stock at a level above that which might otherwise prevail in the open market.
The Underwriters are not required to engage in these activities and, if
commenced, may end any of these activities at any time.
 
PRICING OF THIS OFFERING
 
     Prior to this offering, there has been no public market for our Common

price were:

To the Board of Directors and Stockholders
of MarketWatch.com, Inc.
 
     In our opinion, the accompanying balance sheet and the related statements
of operations, of stockholders' equity (deficit) and of cash flows present
fairly, in all material respects, the financial position of MarketWatch.com,
Inc. at December 31, 1997 and June 30, 1998, and the results of its operations
and its cash flows for the period from inception (October 29, 1997) through
December 31, 1997 and the six months ended June 30, 1998 in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audits to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1 -- ORGANIZATION AND NATURE OF BUSINESS:
 
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 is jointly owned by Data Broadcasting Corporation ("DBC")
and CBS Broadcasting Inc. ("CBS") (collectively, the "Members"), with each
Member owning 50% of the Company. The operations of the Company are governed by
a limited liability company agreement dated October 29, 1997 (the "LLC
Agreement"). The Company's Web site, CBS.MarketWatch.com, delivers a wide range
of financial news and information, including real-time and delayed market prices
of stocks, bonds, options and mutual funds and original news and commentary from
financial and market analysts, economists and reporters, all of which is
available to viewers. However, certain proprietary information and real-time
market prices are available only through subscriptions to MarketWatch RT and
MarketWatch Live products. In September 1998, the Company's Board of Directors
approved the reorganization of the limited liability company into a corporation.
All share and per share data have been retroactively adjusted to reflect the
reorganization, which will take effect immediately prior to the closing of the
Company's initial public offering of Common Stock ("IPO") (See Note 8).
 
     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 is required to contribute 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 consists of customer contracts and intellectual
property in return for its ownership position. CBS will provide $50 million of
rate card amount advertising and promotions over a period of five years in
return for its ownership position. Under the terms of the Stockholders
Agreement, the $50 million rate card amount has been revised to $30 million upon
completion of the IPO (See Note 8).
 
     In addition, CBS and the Company have entered into a license agreement
dated October 29, 1997 (the "License Agreement") where CBS, in exchange for 30%
of net advertising revenue, as defined, has 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
charges the Company for certain general services, the Company receives payment
from DBC for supplying news and the Company receives a fee for licensing
MarketWatch RT and MarketWatch Live, respectively (See Notes 7 and 8).
 
     Immediately prior to the closing of its IPO, the Company entered into a
Stockholders' Agreement, Amended and Restated Services and License Agreements, a
Registration Rights Agreement and a Revolving Credit Agreement. (See Note 8).
 
ACCOUNTING FOR THE INITIAL CAPITALIZATION OF THE COMPANY
 
     The Company has recorded DBC's equity contributions under the Contribution
Agreement at the value of the cash contributed. DBC's contribution of the
intellectual property of the Online/ News business has been recorded at its
historical carrying amount, which is zero. DBC contributed none of the tangible
assets or liabilities of the Online/News business; only intellectual property.
The Company has recorded the contribution of the Online/News business at its
historical carrying

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
amount since the fair value of the business is not objectively determinable by a
corresponding contribution of monetary assets by CBS.
 
     As described above, CBS has committed to provide advertising and promotions
over a five-year period in return for its ownership position. The Company has
recorded the $50 million commitment by CBS as a contribution receivable and will
reduce the receivable and record an expense based on the rate card amount of the
advertising and promotion during the period provided. (See Note 7). Under the
terms of the Stockholders Agreement, the Company will record a $20 million
reduction to the contribution receivable and additional paid-in capital upon
completion of the IPO (See Note 8).
 
NEED FOR FUTURE CAPITAL AND INITIAL PUBLIC OFFERING
 
     The Company has sustained losses and negative cash flows from operations
since inception and expects these conditions to continue for the foreseeable
future. As of September 30, 1998, the Company has an accumulated deficit of
$8,250,000. The implementation of the Company's business plan is dependent on
obtaining additional financing through public or private financing, strategic
relationships or other arrangements. There can be no assurance that such
additional financing will be available on terms attractive to the Company, or at
all. Should additional financing not be available, management believes that the
Company's current growth plans would be curtailed and sufficient funds would be
available from operations, DBC and CBS to enable the Company to continue
operations through 1999.
 
     In September 1998, the Board of Directors authorized the Company to proceed
with the IPO.
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
Revenue recognition
 
     The Company generates its revenues from three primary sources: the sale of
advertising on the Company's Web site, subscriptions to premium services
available through the Web site and the sale of news to DBC.
 
     Advertising revenue, derived from the sale of banner advertisements and
sponsorships on the Company's Web site, is recognized ratably in the period the
advertising is displayed, provided that no significant Company obligations
remain and collection of the resulting receivable is probable. Company
obligations typically include guarantees of a minimum number of "impressions,"
or times that an advertisement is viewed by users of the Company's Web site.
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 at the
third-party Web site by linked customers. Such amounts are recognized as revenue
in the month earned.
 
     Subscription revenue relates to customer subscriptions to the DBC premium
online services, MarketWatch RT and MarketWatch Live, which provide subscribers
access to real time exchange data and premium analytical products and are sold
through the Company's Web site. Subscriptions 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.
 
     Revenue related to the sale of news to DBC is recognized in the month the
services are provided.

                             MARKETWATCH.COM, INC.
 
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
     Revenues from barter transactions are recognized in accordance with the
provisions of Accounting Principles Board Opinion No. 29 ("APB 29") during the
period in which the advertisements are displayed on the Company's Web site.
Under the provisions of APB 29, barter transactions are recorded at the fair
value of the goods or services received. To date, barter transactions have been
insignificant.
 
Property and equipment
 
     Property and equipment is recorded at cost and depreciated using the
straight-line method over its estimated useful life, ranging from three to five
years. Leasehold improvements are depreciated using the straight-line method
over the shorter of their useful lives or the remaining lease term.
 
Interim financial data
 
     The accompanying financial statements as of September 30, 1998 and for the
nine months then ended are unaudited. In the opinion of management, these
interim statements have been prepared on the same basis as the audited financial
statements and include all adjustments, consisting only of normal recurring
adjustments, necessary for the fair presentation of the results of the interim
periods. The financial and other data disclosed in these notes to the financial
statements for these periods are also unaudited. The results of the operations
for the interim periods are not necessarily indicative of the results to be
expected for any future periods.
 
Basic and diluted net loss per share
 
     The Company computes net loss per share in accordance with the provisions
of Statement of Financial Accounting Standards No. 128, "Earnings per Share"
("SFAS 128") and SEC Staff Accounting Bulletin No. 98 ("SAB 98"). Under the
provisions of SFAS 128 and SAB 98, basic and diluted net loss per share is
computed by dividing the net loss available to common stockholders for the
period by the weighted average number of common shares outstanding for the
period. The calculation of diluted net loss per share excludes shares of common
stock issuable upon exercise of employee stock options as the effect of the
exercise would be antidilutive.
 
Product development costs
 
     Product development costs primarily consist of costs attributable to the
development of new products and are expensed as incurred.
 
     The Company develops software which enables users to access information on
its Web site and subscription services. Development costs incurred prior to
technological feasibility are expensed as incurred. The Company defines
establishment of technological feasibility as the completion of a working model.
Software development costs incurred subsequent to the establishment of
technological feasibility through the period of market availability of products
are capitalized. Costs eligible for capitalization have been immaterial for all
periods presented.
 
Promotion and advertising
 
     Advertising costs are expensed as incurred. Promotion and advertising
provided by CBS under the Contribution Agreement, will be recognized as an
expense and capital contribution during the period in which the services are
provided based on the rate card value of such services (See Note 7). For the
period from inception (October 29, 1997) through December 31, 1997 promotion and
advertising services provided by CBS were not material. For the six months ended
June 30,

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
1998 and the nine months ended September 30, 1998, $3,423,000 and $5,000,000 was
expensed for promotion and advertising services provided by CBS, respectively.
 
Use of estimates in the financial statements
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect amounts reported in the financial statements. Actual
results could differ from those estimates.
 
Concentrations of credit risk
 
     Financial instruments that potentially subject the Company to a significant
concentration of credit risk consist primarily of cash and accounts receivable.
Management deposits all its cash with a single financial institution. Management
periodically performs credit evaluations of its customers' financial condition
and generally does not require collateral on accounts receivable. Most of the
Company's accounts receivable are from Internet-related businesses. As of
December 31, 1997, four customers comprised 53% of gross accounts receivable. As
of June 30, 1998, one customer comprised 16% of the gross accounts receivable
balance and as of September 30, 1998, another customer comprised 11% of the
gross accounts receivable balance. The fair value of accounts receivable
approximates cost due to their short-term nature.
 
Stock-based compensation
 
     The Company accounts for its stock-based employee compensation agreements
in accordance with the provisions of Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" and complies with the disclosure
provisions of Statement of Financial Accounting Standards No. 123, "Accounting
for Stock Based Compensation."
 
Recent accounting pronouncements
 
     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131 ("SFAS 131"), "Disclosure about Segments
of an Enterprise and Related Information." SFAS 131 establishes new standards
for the way companies report information about operating segments in annual
financial statements. The disclosures prescribed by SFAS 131 are effective for
the year ending December 31, 1998. The Company does not believe it operates in
more than one segment.

NOTE 4 -- OPTIONS:
 
     The Members and the management committee of the LLC authorized options to
purchase membership interests in the Company may be granted to officers and
employees of the Company. For the nine months ended September 30, 1998, the
Company recorded $1,390,000 of deferred compensation expense representing the
difference between the deemed fair value by the Company's Board of Directors of
the common stock on the date of grant and the option exercise price on the date
of grant. Deferred compensation will be amortized over the three year vesting
period of the options. During the nine months ended September 30, 1998, $131,000
of deferred compensation was recognized as expense. The fair market value of the
membership interest is determined by the Board of Directors on the date of
grant. In determining the fair market value of the membership interest on each
grant date, the Board of Directors considered, among other things, the value of
assets contributed to the Company from DBC, the Company's absolute and relative
level of revenues and other operating results, the state of the Company's
Website development, the absence of a public trading market for the Company's
securities, the intensely competitive nature of the Company's market and the
appreciation of stock values of a number of generally comparable Internet
companies. Each option will convert into an option to purchase the equivalent
percentage of Common Stock upon the reorganization of the limited liability
company into a corporation, as discussed in Note 8. The following table reflects
the option activity restated to reflect the reorganization.

     The Company applies APB No. 25 and related Interpretations in accounting
for its stock option plan. Had the Company's stock based compensation cost been
determined based on the minimum value at the grant date for awards under the
method prescribed by SFAS No. 123, the Company's net loss would have been
increased to the pro forma amounts indicated below:

     The Company calculated the value of each option grant using the minimum
value method with the following assumptions: no dividend yield, weighted average
expected option term of 5 years: risk free interest rates of 5.5% to 5.7%, 5.8%
to 6.4% and 5.5% to 6.4% for the period from inception (October 29, 1997)
through December 31, 1997, for the six months ended June 30, 1998 and for the
nine months ended September 30, 1998 (unaudited), respectively.
 
     Because the determination of fair value of all options granted after such
time as the Company becomes a public entity will include an expected volatility
factor in addition to the factors described in the preceding paragraph, the
above results may not be representative of future periods.
 
NOTE 5 -- INCOME TAXES:
 
     No benefit for federal and state income taxes is reported in the financial
statements as the Company has elected to be taxed as a partnership prior to the
reorganization of the limited liability company into a Corporation, which will
take effect immediately prior to the closing of the IPO (Note 8). Therefore, the
federal and state tax effects of the Company's results of operations are
recorded by the Members in their respective income tax returns.
 
     Subsequently, the Company will account for income taxes in accordance with
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" ("SFAS No. 109"). Had the Company applied the provision of SFAS No. 109
for the period from inception (October 1997)

through June 30, 1998, the Company would have recorded a deferred tax asset,
primarily from net operating loss carryforwards, and a full valuation allowance.
Net operating loss carryforwards generated during the period would have been
approximately $1,100,000.
 
NOTE 6 -- COMMITMENTS:
 
     Beginning in April 1998, the Company subleases office space for its
corporate headquarters in San Francisco, California from CBS. Rent expense under
the sublease was $19,000 for the six months ended June 30, 1998 and $58,000 for
the nine months ended September 30, 1998 (unaudited). Future annual minimum
lease payments under the leases were as follows:

     The Company has entered into employment agreements with two of its officers
which expire in June 2001. Such agreements provide for minimum annual salary
levels ranging from $200,000 to $240,000, as well as annual bonuses of up to 50%
of the base salary.
 
     The Company maintains agreements with independent content providers for
certain news, stock quotes and other information. The terms of these agreements
are generally one year, with optional extension periods ranging from one to
three years. Minimum payments under these agreements for the year ending
December 31, 1998 are $60,000.
 
NOTE 7 -- RELATED PARTY TRANSACTIONS:
 
     Under the LLC Agreement, DBC will advance the Company up to an aggregate of
$5,000,000 through October 29, 2000. Borrowings bear interest at a variable rate
per annum equal to The Chase Manhattan Bank's prime rate plus 2% (10.5% as of
June 30, 1998 and 10.25% at September 30, 1998) and are repayable at such time
as the Company has sufficient cash, as determined by the Members. Prior to the
formation of the Company and contribution of the intellectual property (See Note
1), the Online/News business owed DBC $2.7 million. The amounts due under this
intercompany obligation were not assumed by the Company.

a Services Agreement dated October 29, 1997, DBC will provide the Company with
certain general services which include cash management, accounting, network
operations and hosting of the Company's Web pages and data feeds. Charges for
these services and equipment usage are allocated based upon DBC management's
estimate of costs attributable to the operations of MarketWatch.com. Such fees
totaled $70,000 for the period from inception (October 29, 1997) through
December 31, 1997, $340,000 for the six months ended June 30, 1998 and $517,000
for the nine months ended September 30, 1998 (unaudited).
 
     The Company is required by the Services Agreement to share net revenue from
its current subscription services with DBC. The Services Agreement requires DBC
to pay the Company 25% and 75% of the Net Revenues of MarketWatch RT and
MarketWatch Live, respectively. The Services Agreement defines "Net Revenues" as
gross subscription fees collected, less various direct costs. These direct
charges included in cost of revenue and totaled $16,000 for the period from
inception (October 29, 1997) through December 31, 1997, $77,000 for the six
months ended June 30, 1998 and $117,000 for the nine months ended September 30,
1998 (unaudited).
 
     The Services Agreement also provides for the Company to sell its
proprietary news and commentary to DBC in exchange for a fee based on the number
of DBC subscribers. These fees amounted to $210,000 for the period from
inception (October 29, 1997) through December 31, 1997, $627,000 for the six
months ended June 30, 1998, and $949,000 for the nine months ended September 30,
1998 (unaudited). For the five years ending October 29, 2002, these fees are
subject to a monthly minimum of $100,000.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
     DBC provided office space at various facilities to the Company through June
30, 1998. The Company has recorded rent expense of $15,000 for the period from
inception (October 29, 1997) through December 31, 1997 and $50,000 for the six
months ended June 30, 1998 related to the rent provided by DBC based upon an
allocation methodology using its occupancy percentage and the rental amount paid
by DBC. Management believes the allocation methodology to be reasonable. Such
amounts have been recorded as capital contributions.
 
     Under the License Agreement, the Company is required to pay to CBS 30% on
certain net advertising revenues, as defined, in excess of the first $1,000,000
as compensation for licensing CBS' news content and trademarks. No amounts have
been accrued under the agreement for the period from inception (October 29,
1997) through December 31, 1997 and for the six months ended June 30, 1998.
$148,000 has been accrued at September 30, 1998 under the License Agreement
(unaudited).
 
     Under the terms of the Contribution Agreement, CBS will provide advertising
and promotions over a five year period. The Company will record an expense at
the time the advertising and promotion is provided based on the rate card value.
The Company has recorded advertising expense of $3,423,000 at rate card value
for the six months ended June 30, 1998 and $5,000,000 at rate card value for the
nine months ended September 30, 1998 (unaudited) related to advertising and
promotion provided by CBS. As of September 30, 1998, CBS is committed to provide
$25,000,000 rate card amount of advertising and promotions, assuming execution
of the Stockholders' Agreement prior to closing the IPO (See Note 8).
 
     An executive of the Company is also a member of the Board of Directors of a
customer. For the period from inception (October 29, 1997) through December 31,
1997 $40,000 of advertising revenues were attributable to this customer. For the
six months ended June 30, 1998 and nine months ended September 30, 1998 no
revenue was attributable to this customer.
 
     CBS provides office space at its facility in New York and association with
the CBS name to the Company in exchange for access to certain news content and
news personnel. The Company has not recorded any revenue or expense for this
barter transaction for the periods presented because such amounts are
insignificant.
 
     Under the terms of an insertion order, DBC has committed to purchase
approximately $225,000 of advertising from the Company in 1998 and approximately
$500,000 of advertising from the Company in each of 1999 and 2000. At September
30, 1998, DBC had purchased $108,000 of advertising under the insertion order.
This commitment may be terminated by DBC on 30 days' notice.

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.
 
     The terms of the Amended and Restated License will not prohibit CBS from
licensing its name and logo to certain other Web sites or Internet services. CBS

another Web site or Internet service.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1 -- ORGANIZATION AND NATURE OF BUSINESS:
 
     The accompanying financial statements and related notes reflect the
carve-out historical results of operations and financial position of the online
and news business ("DBC Online/News" or "Business") of Data Broadcasting
Corporation ("DBC"). The Statement of Operations includes all revenues and costs
directly attributable to DBC Online/News, including costs for facilities,
functions and services used by the Business at shared sites and allocations of
costs for certain administrative functions and services performed by centralized
departments within DBC. Cost have been allocated to the Business based on DBC
management's estimate of costs attributable to the operation of the online and
new business. Such costs are not necessarily indicative of the costs that would
have been incurred if DBC Online/News had been a separate entity.
 
     On October 29, 1997, DBC and CBS Broadcasting Inc. ("CBS") agreed to form a
limited liability company, Marketwatch.Com, LLC ("MarketWatch") for the purpose
of providing business information over the Internet. In connection with the
formation of MarketWatch, DBC and CBS entered into several agreements, including
a Limited Liability Company Agreement (the "LLC Agreement") and a Contribution
Agreement (the "Contribution Agreement"). Under the terms of the Contribution
Agreement, DBC has contributed the rights to certain assets associated with the
Business, and $2 million in cash in exchange for a 50% ownership interest. CBS
will provide, subject to termination on the occurrence of certain events, over a
period of five years, promotion and advertising time in exchange for a 50%
ownership interest. In addition, CBS has granted to the Company, subject to
certain licensing fees, the non-exclusive right and license to certain CBS news
contents and registered trademarks including the CBS "Eye" design, for five
years. These financial statements are not necessarily indicative of results that
would have occurred if DBC Online/News had been a separate stand-alone entity
during the periods presented or of the future results of MarketWatch.
 
     DBC Online/News provided a Web site (MarketWatch.com) that delivers a broad
range of financial news and information, including delayed market prices of
stocks, bonds, options and mutual funds and original news and commentary from
financial and market analysts, economists and reporters. DBC Online/News also
provided certain proprietary information and real-time market prices available
only through subscriptions to its MarketWatch RT online service.
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
REVENUE RECOGNITION
 
     DBC Online/News generates its revenues from two sources: the sale of
advertising on the Business' Web site and subscriptions to premium services
available through the Web site.
 
     Advertising revenue, which is derived from the sale of advertising on the
DBC Online/News Web site, is recognized in the period the advertising is
displayed, provided that no significant DBC Online/News obligations remain and
collection of the resulting receivable is probable. DBC Online/News obligations
typically include guarantees of a minimum number of "impressions", or times that
an advertisement is viewed by users of the Web site. As of December 31, 1996 and
October 28, 1997, DBC Online/News believes that no reserve is necessary for such
obligations.
 
     Subscription revenue relates to customer subscriptions to the Business'
premium online service, MarketWatch RT. MarketWatch RT provides subscribers
access to real time exchange data and premium analytical products through the
Business' Web site. Subscriptions are charged to customers' credit cards and are
billed in advance on a monthly basis. Revenue from subscriptions is

                             (PREDECESSOR BUSINESS)
 
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
recognized ratably over the subscription period. Deferred revenues relate to
subscription fees collected but for which revenue has not been recognized.
 
EQUIPMENT
 
     Equipment, which consists primarily of personal computers and general
business software for use by employees, is recorded at cost and depreciated
using the straight-line method over its estimated useful life, ranging from
three to five years. Accumulated depreciation was $63,000 and $149,000 at
December 31, 1996 and October 28, 1997, respectively.
 
PRODUCT DEVELOPMENT COSTS
 
     DBC Online/News develops software which enables users to access information
on its Web site and subscription service. Development costs incurred prior to
technological feasibility are expensed as incurred. DBC Online/News defines
establishment of technological feasibility as the completion of a working model.
Software development costs incurred subsequent to the establishment of
technological feasibility through the period of market availability of products
are capitalized. Costs eligible for capitalization have been immaterial for all
periods presented.
 
ADVERTISING
 
     Advertising costs are expensed as incurred. Total advertising expenses were
$0, $74,000 and $9,000 for the period from inception (October 1, 1995) through
December 31, 1995, the year ended December 31, 1996 and the period ended from
January 1, 1997 through October 28, 1997, respectively.
 
INCOME TAXES
 
     The taxable loss of DBC Online/News for the period from inception (October
1, 1995) through December 31, 1995, the year ended December 31, 1996 and period
ended from January 1, 1997 through October 28, 1997 was included in the DBC
consolidated tax returns. Separate income tax returns were not prepared or filed
for DBC Online/News. For all periods presented, deferred income taxes and
related tax expenses have been recorded by applying the asset and liability
approach to each component of DBC Online/New as if it were a separate taxpayer.
Under this approach, deferred tax assets and liabilities represent the expected
future tax consequences of carryforwards and temporary differences between the
carrying amounts and the tax bases of assets and liabilities.
 
     The current tax benefit has been determined as if DBC Online/News was a
separate taxpayer and is deemed to be receivable from DBC in the period it
arose.
 
INTERIM FINANCIAL DATA
 
     The accompanying statement operations and changes in owner's net deficit
for the nine months ended September 30, 1997 are unaudited. In the opinion of
management, these interim statements have been prepared on the same basis as the
audited financial statements and include all adjustments necessary for the four
presentation of the interim period.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
USE OF ESTIMATES IN THE FINANCIAL STATEMENTS
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect amounts reported in the financial statements. Actual
results could differ from those estimates.
 
CONCENTRATIONS OF CREDIT RISK
 
     Financial instruments that potentially subject DBC Online/News to a
significant concentration of credit risk consist primarily of accounts
receivable. Management periodically performs credit evaluations of its
customers' financial condition and generally does not require collateral on
accounts receivable. Most of DBC Online/News accounts receivable as of December
31, 1997 are from Internet-related business.
 
NOTE 3 -- RELATED PARTY:
 
     The accompanying financial statements include costs for cash management,
accounting, legal and network operations, that were provided to the Business by
DBC, in addition to allocated costs for facility charges at shares sites,
including rent and equipment usage. Costs for cash management accounting, legal
and network operations have been allocated to the Business based on DBC
management's estimated percentage of the time spent by DBC employees on the
Business to total department time. The costs for facility charges are based on
the percentage of usage by DBC Online/News to the overall costs. Such
allocations are not necessarily indicative of the costs that would have been
incurred if DBC Online/News had been a separate entity. However, management
believes the differences between the allocated costs and cost to obtain such
services from an outside third party would be insignificant.
 
     Charges allocated to DBC Online/News were $9,000, $295,000 and $306,000 for
the period from inception (October 1, 1995) to December 31, 1995, the year ended
December 31, 1996 and for the period from January 1, 1997 through October 28,
1997, respectively. Of the total charges for the period from inception (October
1, 1995) through December 31, 1995, $9,000 were included in general and
administrative expenses. For the year ended December 31, 1996, allocated charges
of $160,000 and $135,000 were included in cost of revenues and general and
administrative expenses, respectively. For the period January 1, 1997 through
October 28, 1997, allocated charges of $191,000 and $115,000 were included in
cost of revenues and general and administrative expenses, respectively.
 
     Other expenses charged by DBC included in the Statement of Operations
represent actual costs incurred by DBC which were directly attributable to the
Business primarily include payroll and related costs, consulting, commissions,
depreciation and access fees for information from various exchange markets.

     DBC funds the working capital requirements of the Business based upon a
centralized cash management system. Interest on amounts due to DBC is charged at
prime plus 2% (10.5% at October 28, 1997). An analysis of amounts due to DBC is

     Amounts due under the obligation to DBC were not assumed by MarketWatch
(See Note 1) upon formation. Subsequent to October 28, 1997, the amounts due to
DBC would be reduced by cash collected by DBC on existing accounts receivable.
Any remaining obligation has remained outstanding.
 
NOTE 4 -- INCOME TAXES:
 
     The operating results of DBC Online/News were included in the consolidated
tax returns of DBC. The methodology for allocating tax expense to DBC
Online/News is set forth in Note 2. For all periods presented, tax losses
generated by DBC Online/News were used to reduce DBC's taxable income, and
therefore, have been reflected as a current tax benefit.
 
     The benefit for income taxes consists of the following:
