                             ---------------------
 
   
This is an initial public offering of our common stock. We are selling all of
the 3,000,000 shares offered under this prospectus. We anticipate that the
initial public offering price will be between $12.00 and $14.00 per share.
    
 
There is currently no public market for the shares. Our common stock has been
approved for quotation on the Nasdaq National Market under the symbol "MINE."
 
At the same time as we sell the shares offered by this prospectus, we will sell
shares of our common stock to Comcast Interactive Investments, Inc. for
$2,500,000 at a price per share equal to 93% of the initial public offering
price. Since these shares will be sold in a private placement, Comcast will not
be able to immediately resell the shares in the public market. See "Concurrent
Placement."
 
SEE "RISK FACTORS" BEGINNING ON PAGE 5 TO READ ABOUT RISKS THAT YOU SHOULD
CONSIDER BEFORE BUYING SHARES OF OUR COMMON STOCK.
 
NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY OTHER REGULATORY BODY HAS
APPROVED OR DISAPPROVED THESE SECURITIES OR PASSED UPON THE ACCURACY OR ADEQUACY
OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

OUR BUSINESS
 
   
    MININGCO.COM is a leading Internet news, information and entertainment
service. Our service is a network of over 600 web sites, each of which focuses
on a specific topic and is managed by a knowledgeable human guide. Through these
GuideSites-TM-, the guides create and maintain Internet directories that include
approximately 400,000 pre-screened links to other web sites, which are
summarized by the guides, enabling users to quickly find relevant Internet
content. The GuideSite network also provides original high-quality content,
consisting primarily of text, that is created regularly by the guides on
thousands of subjects. Additionally, since our GuideSites focus on specific
topics, users with like interests can form communities by communicating with
each other directly or through the guides. We believe that our service offers an
enjoyable and efficient Internet experience for users across a broad range of
topics, creating highly targeted marketing opportunities for advertisers and for
businesses that market their products and services over the Internet. We believe
that over 4.6 million unique users visited MININGCO.COM in January 1999, making
MININGCO.COM the sixth largest news/ information/entertainment Internet property
in terms of audience reach and the 26th largest Internet property overall in
that month.
    
 
    MININGCO.COM'S guides are located in over 40 states and 18 countries. We use
a work force of part-time independent contractors because we can draw upon a
broad experience base more cost-effectively than with a large internal editorial
staff. The guides complete a comprehensive 16-week training process and their
GuideSites are monitored for quality and consistency. We have exclusive online
rights to all of the guide-developed content. MININGCO.COM'S guides are
compensated based on the greater of a monthly guarantee or a percentage of
revenues generated by all of the GuideSites.
 
    We believe that our network of GuideSites provides a highly targeted
Internet platform for advertisers and marketers over a broad range of consumer
and business categories. Advertisers and electronic commerce partners have
significant flexibility in determining the level of targeting that they want to
achieve on MININGCO.COM. For several of our electronic commerce partners, we
have developed promotions that integrate original content from MININGCO.COM with
our partners' offerings. We believe these promotions create an engaging
purchasing environment for users, while enhancing the value of our service as an
electronic commerce platform. Some of our recent advertisers and electronic
commerce partners include Bertelsmann Music Group, eBay, IBM, Lowestfare.com,
Microsoft Network, Netscape, Office Max and Qwest.
 
OUR STRATEGY
 
    Our objective is to become a primary Internet destination and a leading
advertising and electronic commerce platform. We are focused on increasing the
number of users and page views on MININGCO.COM by:
 
    - Building brand awareness through expanded online and offline marketing
      campaigns;
 
    - Broadening existing and developing new distribution and syndication
      partnerships; and
 
    - Expanding MININGCO.COM'S functions, features and content.
 
                                       1
<PAGE>
    We also intend to convert user traffic into revenues by:
 
    - Broadening our base of advertisers and electronic commerce partners and
      optimizing our advertising rates by leveraging the increasing flow of user
      traffic in highly targeted sections within the GuideSite network; and
 
    - Expanding our internal advertising sales force, which will enable us to
      establish and maintain closer relationships with our advertisers,
      advertising agencies and electronic commerce marketers, and reduce
      advertising sales costs as a percentage of revenues.

                                  RISK FACTORS
 
    ANY INVESTMENT IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU
SHOULD CONSIDER CAREFULLY THE FOLLOWING INFORMATION ABOUT THESE RISKS, TOGETHER
WITH THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS, BEFORE YOU DECIDE TO
BUY OUR COMMON STOCK. IF ANY OF THE FOLLOWING RISKS ACTUALLY OCCUR, OUR
BUSINESS, RESULTS OF OPERATIONS OR FINANCIAL CONDITION WOULD LIKELY SUFFER. IN
THIS CASE, THE MARKET PRICE OF OUR COMMON STOCK COULD DECLINE, AND YOU MAY LOSE
ALL OR PART OF THE MONEY YOU PAID TO BUY OUR COMMON STOCK.
 
   
BECAUSE WE HAVE ONLY BEEN IN BUSINESS FOR A SHORT PERIOD OF TIME, THERE IS
  LIMITED INFORMATION UPON WHICH YOU CAN EVALUATE OUR BUSINESS.
    
 
    We were incorporated in June 1996 and launched MININGCO.COM in April 1997.
Accordingly, you can only evaluate our business based on our limited operating
history. As a young company, we face risks and uncertainties relating to our
ability to successfully implement our business plan. If we are unsuccessful in
addressing these risks and uncertainties, our business, results of operations
and financial condition will be materially adversely affected.
 
WE HAVE LOST MONEY EVERY QUARTER AND EVERY YEAR, AND WE EXPECT TO LOSE MONEY IN
  THE FUTURE.
 
   
    IF OUR REVENUES DO NOT INCREASE SUBSTANTIALLY, WE MAY NEVER BECOME
PROFITABLE. We have not generated enough revenues to exceed the substantial
amounts we have spent to create, launch and enhance MININGCO.COM and to grow our
business. Even if we do achieve profitability, we may not sustain or increase
profitability on a quarterly or annual basis in the future.
    
 
   
    A PORTION OF OUR HISTORICAL REVENUES HAVE BEEN DERIVED FROM AN ARRANGEMENT
WITH CITIBANK N.A. AND FROM BARTER AGREEMENTS. In 1998, approximately 12% of our
revenues were derived from an advertising arrangement with Citibank, N.A., which
ended on December 31, 1998. In 1998, approximately 10% of our revenues were
derived from agreements where we traded advertisements on MININGCO.COM in
exchange for advertisements on other web sites without receiving any cash
payments. We expect that these barter revenues will continue to account for
approximately 10% of our revenues in the future.
    
 
   
    OUR COSTS OF REVENUES COMBINED WITH OUR OPERATING EXPENSES HAVE EXCEEDED OUR
REVENUES FOR ALL QUARTERS. We have historically funded our operations by selling
our stock and not by generating income from our business. At December 31, 1998,
our accumulated deficit was $26.7 million. We expect to continue to lose money
for the foreseeable future because we plan to continue to incur significant
expenses.
    
 
   
FLUCTUATIONS IN OUR OPERATING RESULTS MAY NEGATIVELY IMPACT OUR STOCK PRICE.
    
 
    Our quarterly operating results may fluctuate significantly in the future
due to a variety of factors that could affect our revenues or our expenses in
any particular quarter. It is possible that in some future periods our results
of operations may be below the expectations of public market analysts and
investors. In this event, the price of our common stock is likely to fall.
 
   
    You should not rely on our results of operations during any particular
quarter as an indication of our results for a full year or any other quarter.
Factors that may affect our quarterly results include:
    
 
    - the demand for advertising on MININGCO.COM;
 
    - the number of users on, and the frequency of their use of, MININGCO.COM
      since our advertising revenues are typically based on user traffic;
 
    - our ability to attract and retain advertisers and electronic commerce
      partners;
 
    - our ability to meet the minimum numbers of advertisements that we are
      required to deliver to users by many of our advertising contracts, since
      our failure to do this would result in our
 
                                       5
<PAGE>
      deferring recognition of the related revenues and would reduce our
      available advertising inventory in subsequent periods;
 
    - changes in rates paid for advertising on MININGCO.COM;
 
    - the timing and amount of our costs related to advertising sales and
      marketing efforts; and
 
    - fees we may pay for distribution or content or other costs we may incur as
      we expand our operations.
 
   
    Our operating expenses are based on our expectations of our future revenues
and are relatively fixed in the short term. Given our limited operating history
and our difficulties in accurately estimating the user traffic historically
experienced on our website, user traffic on our website is difficult to forecast
accurately. Consequently, since revenues from Internet advertising will make up
a significant amount of our revenues for the foreseeable future, our revenues
are difficult to forecast accurately. In particular, we intend to expend
significant amounts to expand our internal advertising sales force and to build
brand awareness of MININGCO.COM. We may be unable to adjust spending quickly
enough to offset any unexpected revenue shortfall. If we have a shortfall in
revenues in relation to our expenses, or if our expenses precede increased
revenues, then our results of operations and financial condition would be
materially adversely affected.
    
 
SEASONAL FACTORS MAY AFFECT OUR QUARTERLY OPERATING RESULTS.
 
    Seasonality of our user traffic on MININGCO.COM and our advertising revenues
may cause our total revenues to fluctuate. User traffic on web sites has
typically declined during the summer and year-end vacation and holiday periods.
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. Similar seasonal or other patterns may develop in our business.
 
   
WE WILL ONLY BE ABLE TO EXECUTE OUR BUSINESS PLAN IF INTERNET USAGE GROWS.
    
 
    Our business would be adversely affected if Internet usage does not grow.
Internet usage may be inhibited for any of the following reasons:
 
    - the Internet infrastructure may not be able to support the demands placed
      on it, and its performance and reliability may decline as usage grows;
 
    - security and authentication concerns with respect to the transmission over
      the Internet of confidential information, such as credit card numbers, and
      attempts by unauthorized computer users, so-called hackers, to penetrate
      online security systems; and
 
    - privacy concerns, including those related to the ability of web sites to
      gather user information without the user's knowledge or consent.
 
   
WE WILL ONLY BE ABLE TO EXECUTE OUR BUSINESS PLAN IF INTERNET ADVERTISING
  INCREASES.
    
 
   
    OUR BUSINESS, RESULTS OF OPERATIONS AND FINANCIAL CONDITION WOULD BE
MATERIALLY ADVERSELY AFFECTED IF THE INTERNET ADVERTISING MARKET DEVELOPS MORE
SLOWLY THAN WE EXPECT OR IF WE ARE UNSUCCESSFUL IN INCREASING OUR ADVERTISING
REVENUES. Revenues from Internet advertising will make up a significant amount
of our revenues for the foreseeable future. Since the Internet advertising
market is new and rapidly evolving, we cannot yet gauge its effectiveness as
compared to traditional advertising media.
    
 
   
    THE ADOPTION OF INTERNET ADVERTISING, PARTICULARLY BY THOSE ENTITIES THAT
HAVE HISTORICALLY RELIED UPON TRADITIONAL MEDIA FOR ADVERTISING, REQUIRES THE
ACCEPTANCE OF A NEW WAY OF CONDUCTING BUSINESS, EXCHANGING INFORMATION AND
ADVERTISING PRODUCTS AND SERVICES. Advertisers that have traditionally relied
upon other advertising media may be reluctant to advertise on the Internet.
These businesses may find Internet
    
 
                                       6
<PAGE>
   
advertising to be less effective than traditional advertising media for
promoting their products and services. Many potential advertising and electronic
commerce partners have little or no experience using the Internet for
advertising purposes. Consequently, they may allocate only limited portions of
their advertising budgets to Internet advertising.
    
 
    ADVERTISERS AND ELECTRONIC COMMERCE MARKETERS MAY NOT ADVERTISE ON
MININGCO.COM OR MAY PAY LESS FOR ADVERTISING ON MININGCO.COM IF THEY DO NOT
BELIEVE THAT THEY CAN RELIABLY MEASURE THE EFFECTIVENESS OF INTERNET ADVERTISING
OR THE DEMOGRAPHICS OF THE USER VIEWING THEIR ADVERTISEMENTS. We use both
internal measurements and measurements provided to us by third parties. If these
third parties are unable to continue to provide these services, we would have to
perform them ourselves or obtain them from another provider. This could cause us
to incur additional costs or cause interruptions in our business while we are
replacing these services. In addition, we are implementing additional systems
designed to record demographic data on our users. If we do not implement these
systems successfully, we may not be able to accurately evaluate the demographic
characteristics of our users. Moreover, "filter" software programs that limit or
prevent advertising from being delivered to an Internet user's computer are
available. Widespread adoption of this software could adversely affect the
commercial viability of Internet advertising.
 
   
    TO THE EXTENT THAT MINIMUM GUARANTEED IMPRESSION LEVELS ARE NOT MET, WE
DEFER RECOGNITION OF THE CORRESPONDING REVENUES UNTIL GUARANTEED IMPRESSION
LEVELS ARE ACHIEVED. Advertising based on impressions, or the number of times an
advertisement is delivered to users, comprises virtually all of our current
revenues. To the extent that minimum impression levels are not achieved for any
reason, we may be required to provide additional impressions after the contract
term, which would reduce our advertising inventory.
    
 
   
    OUR REVENUES COULD BE ADVERSELY AFFECTED IF WE ARE UNABLE TO ADAPT TO OTHER
INTERNET ADVERTISING PRICING MODELS IF THEY ARE ADOPTED. It is difficult to
predict which, if any, pricing models for Internet advertising will emerge as
the industry standard. This makes it difficult to project our future advertising
rates and revenues.
    
 
WE MAY NOT BE ABLE TO ADAPT AS INTERNET TECHNOLOGIES AND CUSTOMER DEMANDS
  CONTINUE TO EVOLVE.
 
    To be successful, we must adapt to rapidly changing Internet technologies by
continually enhancing MININGCO.COM and introducing new services to address our
customers' changing demands. We could incur substantial costs if we need to
modify our services or infrastructure in order to adapt to changes affecting
providers of Internet services. Our business, results of operations and
financial condition could be materially adversely affected if we incurred
significant costs to adapt, or cannot adapt, to these changes.
 
REGULATORY AND LEGAL UNCERTAINTIES COULD HARM OUR BUSINESS.
 
    Any new law or regulation pertaining to the Internet, or the application or
interpretation of existing laws, could decrease the demand for our service,
increase our cost of doing business or otherwise have a material adverse effect
on our business, results of operations and financial condition. There is, and
will be, an increasing number of laws and regulations pertaining to the
Internet. These laws or regulations may relate to liability for information
retrieved from or transmitted over the Internet, online content regulation, user
privacy, taxation and the quality of products and services. Moreover, the
applicability to the Internet of existing laws governing intellectual property
ownership and infringement, copyright, trademark, trade secret, obscenity,
libel, employment, personal privacy and other issues is uncertain and
developing. Please see "Business--Government Regulation and Legal
Uncertainties."
 
                                       7
<PAGE>
WE MAY BE LIABLE FOR THE CONTENT WE MAKE AVAILABLE ON THE INTERNET.
 
    We make content available on MININGCO.COM and on the web sites of our
advertisers and distribution partners. The availability of this content could
result in claims against us based on a variety of theories, including
defamation, obscenity, negligence, copyright or trademark infringement. Other
claims may be brought based on the nature, publication and distribution of our
content or based on errors or false or misleading information provided on
MININGCO.COM, including information deemed to constitute professional advice
such as legal, medical, financial or investment advice. We could also be exposed
to liability for third-party content accessed through MININGCO.COM'S links to
other websites or posted by users in chat rooms or bulletin boards offered on
the GuideSites. Our financial condition could be materially adversely affected
if we were found liable for information that we make available. Implementing
measures to reduce our exposure to this liability may require us to spend
substantial resources and limit the attractiveness of our service to users.
Please see "Business--Government Regulations and Legal Uncertainties."
 
THE DEVELOPMENT OF OUR BRAND IS ESSENTIAL TO OUR FUTURE SUCCESS.
 
   
    If our brand marketing efforts are unsuccessful, our business, financial
condition and results of operations would be materially adversely affected. In
order to build our brand awareness, we must succeed in our brand marketing
efforts, provide high-quality services and increase user traffic on
MININGCO.COM. These efforts have required, and will continue to require,
significant expenses.
    
 
WE MUST INCREASE OUR INTERNAL ADVERTISING SALES FORCE TO SUPPORT OUR GROWTH.
 
   
    Our business, results of operations and financial condition will be
materially adversely affected if we do not develop and maintain an effective
internal advertising sales force. On January 31, 1999, our internal advertising
sales force had nine members. We need to substantially increase our internal
advertising sales force in the near future to support our growth. Our ability to
increase our sales force involves a number of risks and uncertainties,
including:
    
 
    - the competition we face in hiring and retaining advertising sales
      personnel;
 
    - our ability to integrate, train and motivate additional advertising sales
      and advertising sales support personnel;
 
    - our ability to manage a multi-location advertising sales organization; and
 
    - the length of time it takes new advertising sales personnel to become
      productive.
 
WE MAY NOT BE ABLE TO COMPETE SUCCESSFULLY.
 
   
    Competition could result in less user traffic to MININGCO.COM, price
reductions for our advertising inventory, reduced margins or loss of market
share, any of which would have a material adverse effect on our business,
results of operations and financial condition. We face intense competition for
users and for advertisers and electronic commerce marketers. We expect this
competition to increase because there are no substantial barriers to entry in
our market. Competition may also increase as a result of industry consolidation.
We may not be able to compete successfully.
    
 
    We compete for users, advertisers and electronic commerce marketers with the
following:
 
    - Internet retrieval companies, search engines and other Internet "portal"
      companies (such as Excite, InfoSeek, Lycos and Yahoo!);
 
    - online content web sites (such as C--net, ESPN.com and ZDNet.com);
 
    - online community web sites (such as iVillage);
 
                                       8
<PAGE>
    - online personal homepage services (such as GeoCities and theglobe.com);
 
    - publishers and distributors of television, radio and print (such as CBS,
      Disney, NBC and Time Warner);
 
    - general purpose consumer online services (such as America Online and
      Microsoft Network); and
 
    - web sites maintained by Internet service providers (such as AT&T Worldnet,
      Earthlink and MindSpring).
 
    Our ability to compete depends on many factors, many of which are outside of
our control. These factors include the quality of content provided by us and by
our competitors, the ease of use of services developed either by us or by our
competitors, the timing and market acceptance of new and enhanced services
developed either by us or by our competitors, and sales and marketing efforts by
us and our competitors.
 
    Many of our existing competitors, as well as potential new competitors, have
longer operating histories, greater name recognition, larger customer bases and
significantly greater financial, technical and marketing resources than we do.
This may allow them to devote greater resources than we can to the development
and promotion of their services. These competitors may also engage in more
extensive research and development, adopt more aggressive pricing policies and
make more attractive offers to existing and potential employees, guides,
distribution partners, and advertisers and electronic commerce partners. Our
competitors may develop services that are equal or superior to MININGCO.COM or
that achieve greater market acceptance than MININGCO.COM. In addition, current
and potential competitors have established or may establish cooperative
relationships among themselves or with third parties to increase the ability of
their services to address the needs of advertisers and electronic commerce
marketers. As a result, it is possible that new competitors may emerge and
rapidly acquire significant market share.
 
   
WE WOULD BE UNABLE TO PROVIDE CONTENT WITHOUT THE EFFORTS OF OUR NETWORK OF
  GUIDES.
    
 
   
    Our business, results of operations and financial condition would be
materially adversely affected if our guides fail to provide us with adequate
content or if we fail to successfully replace former guides on a timely basis.
We are substantially dependent on our network of guides for providing in-depth,
high-quality, up-to-date content that covers thousands of subjects. Our guides
may not continue to provide us with a sufficient amount of high-quality content
covering a broad enough range of subjects. Furthermore, any number of guides may
discontinue their relationship with us. In addition, since the guides are
independent contractors, we have less control over the content production
process than if the guides were our employees.
    
 
WE COULD INCUR SIGNIFICANT WITHHOLDING TAXES AND EMPLOYEE BENEFITS EXPENSES IF
  THE GUIDES WERE DEEMED TO BE OUR EMPLOYEES RATHER THAN INDEPENDENT
  CONTRACTORS.
 
   
    One or more jurisdictions or taxing authorities, including the Internal
Revenue Service, may seek to treat the guides as our employees rather than
independent contractors. As a result, they may seek to impose taxes, interest or
penalties on us. In addition, employees are generally entitled to healthcare and
other benefits that are typically unavailable to independent contractors. Since
we believe that the guides are independent contractors, we would vigorously
oppose any claim to the contrary. However, our efforts to do so might not be
successful. We have not estimated the minimum quantitative effect that these
taxes or employee benefit costs would have on us if the guides were deemed to be
employees. Our business, results of operations and financial condition would be
materially adversely affected if these claims are made and we do not prevail or
if we are required to treat the guides as employees for tax or employee benefit
purposes or otherwise. Please see "Business--Government Regulation and Legal
Uncertainties."
    
 
                                       9
<PAGE>
WE DEPEND ON RELATIONSHIPS WITH THIRD PARTIES.
 
   
    Our business, results of operations and financial condition could be
materially adversely affected if we do not establish and maintain distribution
relationships on commercially reasonable terms or if any of our distribution
relationships do not result in increased user traffic on MININGCO.COM. A portion
of the users who come to MININGCO.COM come from third-party web sites with which
we have non-exclusive, short-term distribution relationships. Since these web
sites may not attract significant numbers of users themselves, MININGCO.COM may
not receive a significant number of additional users from these relationships.
Moreover, we may have to pay significant fees to establish additional
relationships or maintain existing relationships in the future.
    
 
    In the future, we may also enter into agreements with advertisers,
electronic commerce marketers or other third-party web sites that require us to
exclusively feature these parties in certain sections or on certain pages of
MININGCO.COM. These exclusivity agreements may limit our ability to enter into
other advertising or sponsorship agreements or other strategic relationships.
Many companies we may pursue for strategic relationships also offer competing
services. As a result, these competitors may be reluctant to enter into
strategic relationships with us.
 
WE MAY NOT EFFECTIVELY MANAGE OUR GROWTH.
 
    In order to execute our business plan, we must grow significantly. This
growth will place a significant strain on our personnel, management systems and
resources. If we do not manage growth effectively, our business, results of
operations and financial condition would be materially adversely affected. We
expect that the number of our employees, including management-level employees,
will continue to increase for the foreseeable future. Some of our key employees
have recently been hired, including our Vice President--Marketing who was hired
in November 1998 and our Chief Financial Officer who was hired in January 1999.
These individuals do not have significant experience working with us or our
management team. In addition, we expect that the number of guides will continue
to increase as new GuideSites are established. We must continue to improve our
operational and financial systems and managerial controls and procedures, and we
will need to continue to expand, train and manage our workforce. We must also
maintain close coordination among our technical, accounting, finance, marketing,
sales and editorial organizations.
 
WE DEPEND ON OUR KEY PERSONNEL.
 
    Our future success depends, in part, on the continued service of our key
management personnel, particularly Mr. Scott P. Kurnit, our President and Chief
Executive Officer, and Mr. William C. Day, our Chief Operating Officer. Although
we are the beneficiary of a key person life insurance policy on Mr. Kurnit's
life, the loss of his services, or the services of other key employees, would
have a material adverse effect on our business, results of operations and
financial condition. Our future success also depends on our ability to attract,
retain and motivate highly skilled employees. Competition for employees in our
industry is intense. We may be unable to attract, assimilate or retain other
highly qualified employees in the future. We have from time to time in the past
experienced, and we expect to continue to experience in the future, difficulty
in hiring and retaining highly skilled employees with appropriate
qualifications.
 
THE PERFORMANCE OF MININGCO.COM IS CRITICAL TO OUR BUSINESS AND TO OUR
  REPUTATION.
 
    Any system failure, including network, software or hardware failure, that
causes an interruption in our service or a decrease in responsiveness of
MININGCO.COM could result in reduced user traffic on MININGCO.COM and reduced
revenue. MININGCO.COM has in the past experienced slower response times and
interruptions in service for a variety of reasons. MININGCO.COM could also be

limits and therefore our insurance may not adequately compensate us for any
losses that may occur due to any interruptions in our service.
 
   
    In January 1998, we entered into an Internet-hosting agreement with Frontier
Global Center ("Frontier") to maintain all of our production servers at
Frontier's Manhattan Data Center until February 1, 2000. Our operations depend
on Frontier's ability to protect its and our systems against damage from fire,
power loss, water damage, telecommunications failures, vandalism and other
malicious acts, and similar unexpected adverse events. Any disruption in the
Internet access provided by Frontier could have a material adverse effect on our
business, results of operations and financial condition.
    
 
    Our users and our guides depend on Internet service providers, online
service providers and other web site operators for access to MININGCO.COM. Each
of these providers has experienced significant outages in the past, and could
experience outages, delays and other difficulties due to system failures
unrelated to our systems.
 
WE MAY BE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS AND WE MAY BE
  LIABLE FOR INFRINGING THE INTELLECTUAL PROPERTY RIGHTS OF OTHERS.
 
    Third parties may infringe or misappropriate our patents, trademarks or
other proprietary rights, which could have a material adverse effect on our
business, results of operations or financial condition. While we enter into
confidentiality agreements with our material employees, guides, consultants and
strategic partners, and generally control access to and distribution of our
proprietary information, the steps we have taken to protect our proprietary
rights may not prevent misappropriation. In addition, we do not know whether we
will be able to defend our proprietary rights since the validity, enforceability
and scope of protection of proprietary rights in Internet-related industries is
uncertain and still evolving.
 
    Third parties may assert infringement claims against us. From time to time
in the ordinary course of business we have been, and we expect to continue to
be, subject to claims of alleged infringement of the trademarks and other
intellectual property rights of third parties. These claims and any resultant
litigation, should it occur, could subject us to significant liability for
damages. In addition, even if we prevail, litigation could be time-consuming and
expensive to defend, and could result in the diversion of our time and
attention. Any claims from third parties may also result in limitations on our
ability to use the intellectual property subject to these claims unless we are
able to enter into agreements with the third parties making these claims.
 
WE WOULD LOSE REVENUES AND INCUR SIGNIFICANT COSTS IF OUR SYSTEMS OR MATERIAL
  THIRD-PARTY SYSTEMS ARE NOT YEAR 2000 COMPLIANT.
 
    We have not yet devised a Year 2000 contingency plan. The failure of our
internal systems, or any material third-party systems, to be Year 2000 compliant
would have a material adverse effect on our business, results of operations and
financial condition. Although we believe that each of our material systems is
Year 2000 compliant, we will not conduct an end-to-end system test until the
second quarter of 1999. Accordingly, we do not yet know whether our internal
system, as a whole, is Year 2000 compliant. We are also contacting our
third-party vendors, licensors and providers of hardware, software and services
regarding their Year 2000 readiness. Although Frontier has represented to us
that its internal systems are Year 2000 compliant, their failure to be compliant
would adversely affect our ability to deliver our service. Please see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Impact of the Year 2000."

WE CANNOT PREDICT OUR FUTURE CAPITAL NEEDS AND WE MAY NOT BE ABLE TO OR OUR
  ABILITY TO SECURE ADDITIONAL FINANCING.
    
 
   
    We may need to raise additional funds in the future in order to fund more
aggressive brand promotion or more rapid expansion, to develop new or enhanced
services, to respond to competitive pressures or to make acquisitions. Any
required additional financing may not be available on terms favorable to us, or
at all. If adequate funds are not available on acceptable terms, we may be
unable to fund our expansion, successfully promote our brand, or take advantage
of acquisition opportunities, develop or enhance services, respond to
competitive pressures or take advantage of acquisition opportunities, any of
which could have a material adverse effect on our business, results of
operations and financial condition. If additional funds are raised by our
issuing equity securities, stockholders may experience dilution of their
ownership interest and the newly issued securities may have rights superior to
those of the common stock. If additional funds are raised by our issuing debt,
we may be subject to limitations on our operations, including limitations on the
payment of dividends. We currently anticipate that the net proceeds from this
offering and the concurrent placement, together with currently available funds,
will be sufficient to meet our anticipated needs for at least the next 12
months. Please see "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources."
    
 
FUTURE SALES OF COMMON STOCK BY OUR EXISTING STOCKHOLDERS COULD ADVERSELY AFFECT
  OUR STOCK PRICE.
 
    The market price of our common stock could decline as a result of sales by
our existing stockholders of shares of common stock in the market after this
offering, or the perception that these sales could occur. These sales also might
make it more difficult for us to sell equity securities in the future at a time
and at a price that we deem appropriate. Please see "Shares Eligible for Future
Sale."
 
AFTER THIS OFFERING AND THE CONCURRENT PLACEMENT, OUR OFFICERS AND DIRECTORS MAY
  STILL CONTROL US.
 
    Our executive officers and directors will, in the aggregate, beneficially
own approximately 38.3% of the common stock following this offering and the
concurrent placement. These stockholders may be able to exercise control over
all matters requiring approval by our stockholders, including the election of
directors and approval of significant corporate transactions. This concentration
of ownership may also have the effect of delaying or preventing a change in
control of us, which could have a material adverse effect on our stock price.
Please see "Principal Stockholders."
 
   
OUR SHARES MAY EXPERIENCE EXTREME PRICE AND VOLUME FLUCTUATIONS.
    
 
    The market for the stocks of Internet-related companies has experienced
extreme price and volume fluctuations. Following this offering, investor
interest in us may not lead to the development of an active or liquid trading
market. The market price of our common stock may be volatile, and may decline
below the initial public offering price. In the past, securities class action
litigation has often been instituted against a company following periods of
volatility in the market price of the company's securities. If instituted
against us, regardless of the outcome, litigation could result in substantial
costs and a diversion of our management's attention and resources and have a
material adverse effect on our business, results of operations and financial
condition.
 
YOU WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION.
 
    The initial public offering price per share will significantly exceed the
net tangible book value per share. Accordingly, investors purchasing shares in
this offering will suffer immediate and substantial dilution of their
investment. Please see "Dilution."

                              CONCURRENT PLACEMENT
 
    On February 23, 1999, MiningCo and Comcast Interactive Investments, Inc.
entered into a common stock purchase agreement pursuant to which MiningCo has
agreed to sell to Comcast shares of common stock for a total of $2,500,000.
Comcast will purchase the shares at a price equal to 93% of the initial public
offering price per share. Since Comcast will purchase the shares directly from
MiningCo in a private placement, the underwriters will not receive any discount
or commission on the sale of these shares. The closing of this concurrent
placement is contingent on, and is scheduled to close simultaneously with, the
closing of this offering.
 
    The shares being sold in the concurrent placement will not be registered for
immediate resale under the Securities Act. As a result, Comcast will not
immediately be able to sell its shares in the public market. However, Comcast
will become a party to MiningCo's amended and restated investors' rights
agreement. Pursuant to this agreement, Comcast will be able to have its shares
of common stock registered for resale under the Securities Act at various times
in the future. See "Description of Securities--Registration Rights" and "Shares
Eligible for Future Sale."
 
                    FORWARD LOOKING STATEMENTS; MARKET DATA
 
    Many statements made in this prospectus under the captions "Prospectus
Summary," "Risk Factors," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business" and elsewhere are
forward-looking statements that are not based on historical facts. Because these
forward-looking statements involve risks and uncertainties, there are important
factors that could cause actual results to differ materially from those
expressed or implied by these forward-looking statements, including those
discussed under "Risk Factors."
 
   
    This prospectus contains market data related to MiningCo and the Internet.
This market data includes projections that are based on a number of assumptions.
The assumptions include that:
    
 
    - no catastrophic failure of the Internet will occur;
 
    - the number of people online and the total number of hours spent online
      will increase significantly over the next five years;
 
    - the value of online advertising dollars spent per online user hour will
      increase;
 
    - the download speed of content will increase dramatically; and
 
    - Internet security and privacy concerns will be adequately addressed.
 
   
    If any one or more of the foregoing assumptions turns out to be incorrect,
actual results may differ from the projections based on these assumptions. The
failure of these markets to grow at these projected rates may have a material
adverse effect on MiningCo's business, results of operations and financial
condition, and the market price of MiningCo's common stock.

<PAGE>
                                USE OF PROCEEDS
 
   
    The net proceeds to MiningCo from the sale of the shares offered by this
prospectus and in the concurrent placement, after deducting underwriting
discounts and the estimated offering expenses payable by MiningCo, are estimated
to be approximately $37.4 million ($42.8 million if the underwriters'
over-allotment option is exercised in full), assuming an initial public offering
price of $13.00 per share. The principal purposes of this offering are to obtain
additional capital, to create a public market for the common stock and to
facilitate future access by MiningCo to public securities markets.
    
 
   
    MiningCo intends to use the net proceeds of this offering and the concurrent
placement to execute its business plan. As part of this plan, MiningCo expects
to increase its sales and marketing efforts and hire additional internal
advertising sales personnel. In addition, MiningCo expects to use a portion of
the proceeds to fund its capital expenditures. MiningCo estimates that its
capital expenditures will be approximately $4.0 million for 1999, which is
expected to be used for technical infrastructure improvements and for the
expansion of MiningCo's office space. While MiningCo may also use a portion of
the proceeds for acquisitions, MiningCo has no present understandings or
agreements relating to any acquisitions. Other than with respect to its expected
capital expenditures, MiningCo has not yet determined the amount of net proceeds
to be used specifically for any of the other foregoing purposes. Accordingly,
management will have significant flexibility in applying a significant portion
of the net proceeds of this offering and the concurrent placement. Pending any
such use, as described above, MiningCo intends to invest the net proceeds in
interest-bearing instruments.
    
 
                                DIVIDEND POLICY
 
    MiningCo has not declared or paid any cash dividends on its capital stock
since inception and does not expect to pay any cash dividends for the
foreseeable future. MiningCo currently intends to retain future earnings, if
any, to finance the expansion of its business.

                                 CAPITALIZATION
 
    The following table sets forth, as of December 31, 1998, the capitalization
of MiningCo:
 
       - on an actual basis;
 
       - on a pro forma basis to reflect the automatic conversion of all
         outstanding shares of convertible preferred stock into 6,139,640 shares
         of common stock and the automatic forgiveness and cancellation of
         $337,100 in unsecured promissory notes upon the closing of this
         offering and the concurrent placement; and
 
       - on a pro forma as adjusted basis to give effect to the sale of
         3,000,000 shares in this offering and 206,783 shares being sold in the
         concurrent placement after deducting underwriting discounts and the
         estimated offering costs payable by MiningCo, assuming an initial
         public offering price of $13.00 per share.
 
This information should be read together with MiningCo's financial statements
and the notes relating to those statements appearing elsewhere in this
prospectus.

(1) MiningCo expects that there will be 11,551,829 shares of common stock
    outstanding after this offering and the concurrent placement. This number
    includes, in addition to the adjustments described above, 2,848 shares
    issued upon option and warrant exercises that occurred after December 31,
    1998. After the closing of this offering and the concurrent placement, no
    shares of preferred stock will be issued or outstanding. See "Prospectus

                                    DILUTION
 
    The pro forma net tangible book value of MiningCo as of December 31, 1998
was $7,178,100, or $0.86 per share. MiningCo's pro forma net tangible book value
per share is equal to the amount of MiningCo's total assets less intangible
assets less total liabilities, divided by the pro forma number of shares of
common stock outstanding as of December 31, 1998.
 
    Assuming that MiningCo sells the 3,000,000 shares offered by this prospectus
at an initial public offering price of $13.00 per share and the 206,783 shares
being sold in the concurrent placement at a price of $12.09 per share (93% of
$13.00), after deducting the underwriting discounts and the estimated offering
expenses payable by MiningCo, the pro forma net tangible book value of MiningCo
as of December 31, 1998 would have been $44,548,100, or $3.86 per share. This
represents an immediate increase in pro forma net tangible book value of $3.00
per share to existing stockholders and an immediate dilution in pro forma net
tangible book value of $9.14 per share to investors purchasing shares in this
offering. The following table illustrates this per share dilution:

    None of the foregoing tables or calculations assume that any options or

outstanding options and warrants were exercised on the date of the closing of

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION OF THE FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF MININGCO SHOULD BE READ TOGETHER WITH THE FINANCIAL STATEMENTS AND
THE NOTES TO THOSE STATEMENTS INCLUDED ELSEWHERE IN THIS PROSPECTUS. THIS
DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. PLEASE SEE "RISK FACTORS" AND "FORWARD LOOKING STATEMENTS; MARKET
DATA."
 
OVERVIEW
 
    For the period from MiningCo's incorporation on June 27, 1996 through April
1997, MiningCo's operating activities related primarily to the initial
development of MININGCO.COM, recruitment of employees and guides, and the
establishment of MiningCo's organizational and technical infrastructure. Since
the launch of MININGCO.COM in April 1997, revenues and operating expenses have
increased as MiningCo enhanced its network of guides, expanded its editorial and
operating staff, improved MININGCO.COM's functions and features and promoted
MININGCO.COM to increase brand awareness. As part of its marketing efforts,
MiningCo has conducted online campaigns and, beginning in June 1998, an offline
campaign consisting of a national trade magazine print campaign, and outdoor and
radio advertisements in selected cities.
 
    To date, substantially all of MiningCo's revenues have been derived from the
sale of advertisements on MININGCO.COM. These sales have been made both to
companies that advertise their products and services over the Internet and to
electronic commerce marketers. MiningCo expects to derive its revenue
principally from the sale of advertising on MININGCO.COM for the foreseeable
future. MiningCo currently offers advertisers and electronic commerce partners
numerous sizes and types of advertising placement, including banner
advertisements, button advertisements and text links. MiningCo also offers
sponsorship programs and other promotional opportunities to build brand
awareness and drive user traffic to an advertiser's or electronic commerce
partner's web site. To date, sales of advertisements on MININGCO.COM have been
generated primarily by MiningCo's internal advertising sales organization and,
to a lesser extent, by third-party advertising sales representatives. For the
year ended December 31, 1998, a third-party Internet advertising sales
representative organization accounted for approximately 21% of MiningCo's total
revenues. As of January 31, 1999, MiningCo had an internal advertising sales
organization consisting of nine professionals. MiningCo believes that it needs
to significantly increase the size of its internal advertising sales
organization to successfully execute its growth strategy and, accordingly,
MiningCo intends to hire additional advertising sales professionals. By doing
so, MiningCo believes it can reduce its advertising sales costs as a percentage
of revenues and develop and maintain closer relationships with advertisers and
electronic commerce marketers.
 
    Revenues from advertising sales are recognized ratably in the period in
which the advertisement is displayed, provided that no significant MiningCo
obligations remain and collection of the resulting receivable is probable.
Payments received from advertisers prior to displaying their advertisements on
MININGCO.COM are recorded as deferred revenues and are recognized as revenues
ratably as the advertisements are displayed. Pursuant to its agreements with
advertisers, MiningCo generally guarantees a minimum number of impressions, or
times that an advertisement is delivered to users of MININGCO.COM, for a fixed
fee. To the extent these minimum guaranteed impression levels are not met,
MiningCo defers recognition of the corresponding revenues until the guaranteed
impression levels are achieved.
 
    For the year ended December 31, 1998, approximately 10% of MiningCo's
revenues were generated by agreements where MiningCo traded advertisements on
MININGCO.COM in exchange for advertisements on third-party web sites without
receiving any cash payment. The corresponding expenses from these barter
arrangements, which equal the amount of the barter revenues from these
arrangements, are included as a component of cost of revenues.
 
                                       19
<PAGE>
    Advertisers on MININGCO.COM enter into short-term agreements, typically one
to three months in duration. MiningCo's agreements with its electronic commerce
partners are typically longer in duration, ranging from six months to two years
and, in particular cases, these agreements entitle MiningCo to a share of
revenues generated by sales of merchandise and services over a particular
threshold resulting from direct links from MININGCO.COM. Through December 31,
1998, MiningCo had not recognized any material revenues from these revenue
sharing agreements. Any revenues MiningCo derives from these revenue sharing
agreements will be recognized by MiningCo upon notification from its advertisers
and electronic commerce partners of sales attributable to MININGCO.COM.
 
    Guides are currently compensated at an amount equal to the greater of a
monthly minimum guarantee or a percentage of net advertising revenues generated
by the entire GuideSite network, which is distributed among the guides based on
the user traffic on their respective GuideSites. For these purposes, net
advertising revenues has been defined as total advertising revenues received
less particular types of non-cash revenues, third-party advertising sales
representative organization fees and marketing costs. Guides are also currently
entitled to share a percentage of net transaction revenues and net syndication
revenues. In addition, management may distribute a semi-annual discretionary
bonus to guides. Guide compensation, including any compensation that may result
from the grant of stock options to the guides, is included as a component of
cost of revenues.
 
    MiningCo has recorded deferred compensation expense of approximately
$1,716,900 for the year ended December 31, 1998 in connection with the grant of
stock options to employees and directors, representing the difference between
the deemed value of the common stock at the date of grant for accounting
purposes and the exercise price of the related options. This expense is
amortized over the vesting period, typically four years, of the applicable
options. MiningCo currently expects to amortize the following amounts of
deferred compensation expense annually: 1999--$332,000; 2000--$332,000;
2001--$332,000; and 2002--$242,900. However, $92,000 of the deferred
compensation expense will amortize upon the closing of this offering as a result
of an automatic acceleration clause contained within the original terms of the
option plan for a portion of the outstanding options. Amortization of deferred
compensation expense was $478,000 for the year ended December 31, 1998, of which
$27,000 is related to deferred compensation expense for the grant of options to
operations personnel, has been included in cost of revenues.
 
    During January 1999, MiningCo entered into employment arrangements with two
employees. The employment arrangements provide for minimum salary levels, and
incentive compensation and severance benefits. MiningCo granted options to
purchase a total of 133,500 shares of common stock to the two employees. The
exercise price of the options is $4.21 per share. As a result, MiningCo expects
to record deferred compensation expense of approximately $1,173,000 in the first
quarter of 1999 relating to these options based on the difference between the
deemed fair value of the common stock for accounting purposes, in this case the
assumed initial public offering price of $13.00 per share, and $4.21 per share.
This deferred compensation expense will be amortized over the four-year vesting
period of the applicable options.
 
    Upon the closing of this offering, Mining Co intends to grant fully vested,
non-qualified stock options to purchase up to 200,000 shares of common stock to
a substantial majority of its guides. The exercise price per share of these
options is expected to be the initial public offering price of the common stock
and the options are expected to have two year terms. Since the guides are
independent contractors, MiningCo expects to record compensation expense of up
to approximately $1.9 million representing the fair market value of the options
at the date of grant. The resulting compensation expense will be included in
cost of revenues in the quarter in which this offering is consummated.
 
RESULTS OF OPERATIONS
 
    REVENUES.  Revenues consist primarily of advertising revenues on
MININGCO.COM. MININGCO.COM was launched in April 1997. Revenues were $0 for the
period from June 27, 1996 (inception) to
 
                                       20
<PAGE>
December 31, 1996, $391,000 for the year ended December 31, 1997, which included
$73,000 of barter revenues, and $3.7 million for the year ended December 31,
1998, which included $366,000 of barter revenues. During the year ended December
31, 1998, 12% of MiningCo's revenues were derived from an advertising
arrangement with Citibank N.A., which ended on December 31, 1998. The
period-to-period growth in revenues was primarily attributable to an increase in
the number of advertisers and the number of advertisements delivered to users.
MiningCo anticipates that revenues from advertising will continue to account for
substantially all of MiningCo's revenues for the foreseeable future, and that
barter revenues will remain relatively constant as a percentage of Mining Co's
total revenues.
 
    COST OF REVENUES.  Since the launch of MININGCO.COM in April 1997, cost of
revenues has consisted primarily of guide compensation, third-party Internet
advertising sales organization fees, salaries of operations personnel, site
hosting and depreciation costs and barter advertising expenses. In 1996,
MiningCo's first year of operation, cost of revenues consisted of guide fees,
site hosting and depreciation costs incurred in connection with developing
MiningCo's service. Cost of revenues was $91,000 for the period from June 27,
1996 (inception) to December 31, 1996, $1.8 million for the year ended December
31, 1997 and $4.0 million for the year ended December 31, 1998. This
period-to-period growth in cost of revenues was primarily attributable to an
increase in the fees paid to guides, which increased by $1.1 million from 1996
to 1997 and an additional $1.0 million from 1997 to 1998, and in site hosting
and operations costs, which increased by $492,000 from 1996 to 1997 and an
additional $570,000 from 1997 to 1998, which was due to growth in user traffic
on MININGCO.COM. Commencing in June 1998, MiningCo engaged a third-party
Internet advertising sales representative organization to supplement its
internal advertising sales force in selling MININGCO.COM'S advertising inventory
in exchange for a service fee. Fees paid to the third-party Internet advertising
sales organization accounted for an increase of $233,000 in cost of revenues
from 1997 to 1998.
 
    SALES AND MARKETING EXPENSES.  Sales and marketing expenses consist
primarily of online and offline advertising costs, salaries and commissions of
internal sales and marketing personnel, public relations costs, payments to
third-party Internet companies to drive user traffic to MININGCO.COM and other
marketing expenses. In 1996, MiningCo did not dedicate meaningful funds to sales
and marketing as MININGCO.COM was not launched until April 1997. Sales and
marketing expenses were $241,000 for the period from June 27, 1996 (inception)
to December 31, 1996, $1.7 million for the year ended December 31, 1997 and $7.7
million for the year ended December 31, 1998. The period-to-period increase in
sales and marketing expenses from 1996 to 1997 was primarily attributable to the
initiation of MiningCo's online advertising and other promotional expenditures,
which increased by $916,000, as well as increased sales and marketing personnel
and related expenses, which increased by $512,000. The period-to-period increase
in sales and marketing expenses from 1997 to 1998 was primarily attributable to
the initiation of MiningCo's offline marketing and the expansion of online
advertising efforts, which accounted for an increase of $4.9 million, of which
$817,000 was expense related to third-party Internet companies to drive user
traffic to MININGCO.COM, as well as increased sales and marketing personnel and
related expenses, which increased by $329,000. Sales and marketing expenses in
absolute dollars have increased as a result of the continued development and
implementation of MiningCo's branding and marketing campaigns. MiningCo expects
that sales and marketing expenses will continue to increase in absolute dollars
for the foreseeable future as MiningCo increases expenditures for marketing,
promotion and branding, expands its internal advertising sales force and hires
additional marketing personnel.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
consist primarily of salaries and related costs for general corporate functions,
including finance, accounting, facilities and legal expenses, and fees for
professional services. General and administrative expenses were $1.1 million for
the period from June 27, 1996 (inception) to December 31, 1996, $2.4 million for
the year ended December 31, 1997 and $3.7 million for the year ended December
31, 1998. The absolute
 
                                       21
<PAGE>
dollar increase in general and administrative expenses was primarily
attributable to increased salaries and related expenses associated with hiring
additional personnel, which increased by $694,000 from 1996 to 1997 and by
$622,000 from 1997 to 1998, and facility-related expenses, which increased by
$588,000 from 1996 to 1997 and by $622,000 from 1997 to 1998, to support the
growth of MiningCo's operations. MiningCo expects that it will incur additional
general and administrative expenses as it hires additional personnel and incurs
additional costs related to the growth of its business and its operation as a
public company, including directors' and officers' liability insurance of
approximately $175,000 per year, investor relations programs of approximately
$100,000 per year and professional service fees. Accordingly, MiningCo
anticipates that general and administrative expenses will continue to increase
in absolute dollars in future periods.
 
   
    PRODUCT DEVELOPMENT EXPENSES.  Product development expenses include
personnel and consulting costs associated with the design, development and
testing of MININGCO.COM and MiningCo's systems and editorial personnel costs.
MiningCo expenses its product development costs as incurred. Product development
expenses were $948,000 for the period from June 27, 1996 (inception) to December
31, 1996, $2.8 million for the year ended December 31, 1997 and $2.8 million for
the year ended December 31, 1998. MiningCo launched its site in April, 1997. The
increase in absolute dollars in product development expenses from 1996 to 1997
was primarily attributable to increased staffing levels required to design,
develop and test modifications and improvements to MININGCO.COM. Product
development expenses remained constant from 1997 to 1998 due to nonrecurring
consulting fees associated with the pre-launch development of MININGCO.COM
incurred during the first six months of 1997, offset by an increase in staffing
levels in 1998 to support the growth and development of MININGCO.COM. MiningCo
believes that timely deployment of new and enhanced features and technology are
critical to attaining its strategic objectives. Accordingly, MiningCo intends to
continue recruiting and hiring experienced product development personnel and to
make additional investments in product development. MiningCo expects that
product development expenditures will increase in absolute dollars in future
periods.
    
 
    AMORTIZATION OF DEFERRED COMPENSATION EXPENSE.  MiningCo has recorded
deferred compensation expense of $1,716,900 during 1998, for the difference
between the exercise price and the deemed fair value of stock options granted by
MiningCo to employees, consisting of operational and non-operational personnel,
and directors. This amount is being amortized over the vesting periods of the
individual stock options, which are typically four years. During 1998,
amortization of these charges for non-operational personnel amounted to
$451,000. During 1998, amortization of these charges for operational personnel
was $27,000, which amount is included in cost of revenues.
 
   
    OTHER INCOME (EXPENSE), NET.  Other income (expense), net includes interest
expense related to MiningCo's debt and capital lease obligations, net of income
from consulting activities and interest income from MiningCo's cash and cash
equivalents. Other income (expense), net was $(57,000) for the period from June
27, 1996 (inception) to December 31, 1996, $(299,000) for the year ended
December 31, 1997 and $(686,000) for the year ended December 31, 1998. The
change was primarily attributable to interest accrued on outstanding debt
obligations and amortization of debt discount. During 1997, MiningCo provided
consulting services to a major financial institution for an aggregate amount of
$450,000. Pursuant to its agreement with this financial institution, MiningCo
agreed to provide strategic assistance in creating, supporting and managing
customized web sites around which communities on specific areas of interest for
the financial institution's customers would be created. The term of the
agreement was from June 20, 1997 through December 15, 1997. Fees generated by
these services, net of expenses, have been recorded as other income, net of
which $350,000 was recorded for the year ended December 31, 1997. MiningCo did
not provide consulting services during 1998 and does not anticipate providing
consulting services in the future.
    
 
    CUMULATIVE DIVIDENDS AND ACCRETION OF CONVERTIBLE PREFERRED
STOCK.  Cumulative dividends on MiningCo's convertible preferred stock amounted
to $1,196,800 in 1998. In addition, MiningCo
 
                                       22
<PAGE>
   
accreted $33,700 of costs associated with the convertible preferred stock
issuances. Each share of convertible preferred stock was entitled to a
cumulative dividend at a rate of $0.135 per share per annum for the Series A
convertible preferred stock, $0.162 per share per annum for the Series B
convertible preferred stock and $0.176 per share per annum for the Series C
convertible preferred stock. Upon the closing of this offering, 3,346,715 shares
of Series A convertible preferred stock, 6,597,596 shares of Series B
convertible preferred stock and 7,301,811 shares of Series C convertible
preferred stock, representing all of the outstanding shares of convertible
preferred stock, shall automatically convert into 6,139,640 shares of common
stock.
    
 
QUARTERLY RESULTS OF OPERATIONS DATA
 
    The following table sets forth unaudited quarterly statement of operations
data for each of the eight quarters ended December 31, 1998. In the opinion of
management, this data has been prepared substantially on the same basis as the
audited financial statements appearing elsewhere in this prospectus, and
includes all necessary adjustments, consisting only of normal recurring
adjustments necessary for a fair presentation of such data. The quarterly data
should be read together with the financial statements and the notes to those
statements appearing elsewhere in this prospectus. The results of operations for
any quarter are not necessarily indicative of the results of operations for any
future period.
 
    MiningCo has a limited operating history upon which to evaluate its business
and to predict revenues and plan operating expenses. In order to be successful,
MiningCo must attract more user traffic to MININGCO.COM and generate significant
advertising revenues. MiningCo expects its quarterly operating results to vary
significantly in the future due to a variety of factors, many of which are
outside its control. Since MiningCo expects to be substantially dependent on
revenues from advertising for the foreseeable future, its quarterly revenues are
likely to be particularly affected by user traffic levels on MININGCO.COM.
MiningCo launched its service in April 1997 with a significant online marketing
campaign. As a result, MiningCo spent heavily on marketing in the second quarter
of 1997 to help support this launch. During the second half of 1997, MiningCo's
general and administrative expenses declined due to reductions in compensation
of MiningCo's officers. Following the completion of a private equity financing
in April 1998, MiningCo used a portion of the proceeds to begin its offline
marketing campaign. Please see "Risk Factors--Our quarterly operating results
may fluctuate."

LIQUIDITY AND CAPITAL RESOURCES
 
    Since inception, MiningCo has financed its operations primarily through the
private placement of equity securities and the incurrence of indebtedness. As of
December 31, 1998, MiningCo had $10.6 million in cash and cash equivalents.
 
    To date, MiningCo has experienced negative cash flows from operating
activities. Net cash used in operating activities was $6.0 million for the year
ended December 31, 1997 and $9.8 million for the year ended December 31, 1998.
Net cash used in operating activities for these periods was primarily
attributable to MiningCo's net losses during these periods, adjusted for certain
non-cash items, and a higher level of accounts receivable resulting from an
increase in MiningCo's revenues, which was partially offset by increases in
accounts payable, accrued expenses and deferred revenues. For the year ended
December 31, 1998, the increase in net cash used in operating activities was
primarily attributable to MiningCo's net operating loss of $15.6 million offset
by an increase in accounts payable and accrued expenses.
 
    Net cash used in investing activities was $148,000 for the year ended
December 31, 1997 and $2.9 million for the year ended December 31, 1998. All net
cash used in investing activities related to capital expenditures, primarily for
the acquisition of equipment.
 
    Net cash provided by financing activities was $4.8 million for the year
ended December 31, 1997 and $23.1 million for the year ended December 31, 1998.
Net cash provided by financing activities in 1997 was primarily attributable to
net proceeds received by MiningCo from the issuance of notes payable. Net cash
provided by financing activities in 1998 was primarily attributable to net
proceeds from the issuances of loans payable and preferred stock and the
exercise of warrants by investors in December 1998, and, to a lesser extent,
borrowings under a secured credit facility related to equipment financing. At
December 31, 1998, there was no additional availability under this credit
facility and the balance outstanding was $437,500, of which $154,000 is due in
1999, $157,000 in 2000 and $126,500 in 2001. In January and February 1999,
MiningCo entered into a lease line of credit for $781,300 to finance capital
equipment, of which $232,200 is due in 1999, $268,800 in 2000, $273,300 in 2001
and $7,000 in 2002.
 
    As of December 31, 1998, MiningCo's principal capital commitments consisted
of obligations outstanding under capital and operating leases. MiningCo has
spent approximately $3.4 million on capital expenditures since inception,
excluding capital lease agreements. MiningCo estimates that its capital
expenditures will be approximately $4.0 million for 1999. MiningCo currently
expects that its principal capital expenditures through 1999 will relate to
improvements to its technical infrastructure and expansion of MiningCo's office
space.
 
    MiningCo's ability to generate significant revenues is uncertain. MiningCo
has incurred substantial costs to create, launch and enhance MININGCO.COM and to
grow its business. MiningCo incurred net losses of $2.4 million for the period
from June 27, 1996 (inception) to December 31, 1996, $8.6 million for the year
ended December 31, 1997 and $15.6 million for the year ended December 31, 1998.
At December 31, 1998, MiningCo had an accumulated deficit of $27.9 million.
MiningCo expects losses from operations and negative cash flow to continue for
the foreseeable future as a result of its expansion plans and its expectation
that its operating expenses, particularly sales and marketing expenses, will
increase significantly in the next several years. Although MiningCo has
experienced revenue growth in recent periods, MiningCo's revenues may not remain
at their current level or increase in the future. If MiningCo's revenues do not
increase substantially, MiningCo may not achieve profitability, which would have
a material adverse effect on MiningCo's business, results of operations and
financial condition. Even if MiningCo achieves profitability, it may not sustain
or increase profitability on a quarterly or annual basis in the future.
 
    MiningCo currently anticipates that the net proceeds of this offering,
together with the net proceeds of the concurrent placement and available funds,
will be sufficient to meet its anticipated needs for at least the next 12
months. MiningCo may need to raise additional funds in the future in order to
 
                                       24
<PAGE>
fund more aggressive brand promotion or more rapid expansion, to develop new or
enhanced services, to respond to competitive pressures or to make acquisitions.
Any required additional financing may not be available on terms favorable to
MiningCo, or at all. If adequate funds are not available or not available on
acceptable terms, MiningCo may be unable to fund its expansion, successfully
promote its brand, develop or enhance services, respond to competitive pressures
or take advantage of acquisition opportunities, which could have a material
adverse effect on MiningCo's business, results of operations and financial
condition. If additional funds are raised by the issuance of MiningCo's equity
securities, stockholders may experience dilution of their ownership interest and
those securities may have rights superior to those of the holders of the common
stock. If additional funds are raised by the issuance of debt by MiningCo,
MiningCo may be subject to certain limitations on its operations, including
limitations on the payment of dividends.
 
IMPACT OF THE YEAR 2000
 
    Many currently installed computer systems and software products are coded to
accept or recognize only two-digit entries in the date code field. These systems
may recognize a date using "00" as the year 1900 rather than the year 2000. As a
result, computer systems and/or software used by many companies and governmental
agencies may need to be upgraded to comply with Year 2000 requirements or risk
system failure or miscalculations causing disruptions of normal business
activities.
 
    MiningCo is exposed to the risk that the systems on which it depends to
conduct its operations are not Year 2000 compliant.
 
    STATE OF READINESS. MiningCo has substantially completed the process of
determining the Year 2000 readiness of its information technology systems, which
includes the hardware and software necessary to provide and deliver
MININGCO.COM, and its non-information technology systems, including telephone
systems and other office equipment used internally. MiningCo's assessment plan
consists of the following steps:
 
    - evaluating MiningCo's date dependent code, software and hardware and
     evaluating external dependencies
 
    - quality assurance testing of MiningCo's internally-developed proprietary
     software and systems incorporated in MININGCO.COM
 
    - contacting third-party vendors and licensors of material hardware,
     software and services that are related to the delivery of MININGCO.COM
 
    - contacting vendors of material non-information technology systems used by
     MiningCo
 
    - formulating repair or replacement requirements and implementing corrective
     measures
 
    - evaluating the need for, and preparing and implementing, if required, a
      contingency plan
 
    To date, MiningCo's assessment has determined the following:
 
    - Internally developed software and systems have been checked for date
     dependent code, and all material files and systems are Year 2000 compliant.
     MiningCo believes that recently installed code is also Year 2000 compliant.
 
    - MiningCo has been informed by vendors of material hardware and software
     components of its information technology systems that the products used by
     MiningCo are currently Year 2000 compliant.
 
    - MiningCo's hosting service, Frontier Global Center, has certified that its
     systems are Year 2000 compliant.
 
    - Commercial software upon which MiningCo is dependent is either Year 2000
     compliant or will be upgraded to be compliant in the normal course of
     business through upgrades or installation of software patches.
 
    - Substantially all hardware used in MiningCo's network operations and all
     of the hardware used in its office operations has been certified as Year
     2000 compliant by its vendors.
 
                                       25
<PAGE>
    - MiningCo's telephone system, fax machines and mail systems have been
     certified as Year 2000 compliant.
 
    - MiningCo's landlords and third-party advertising sales representative and
     servicing organizations have not yet provided MiningCo with information
     regarding their Year 2000 compliance.
 
    While MiningCo has assessed the Year 2000 readiness of each of its material
internal systems, it will not conduct an end-to-end system test until the second
quarter of 1999. Accordingly, MiningCo cannot yet assess whether its internal
system, as a whole, is Year 2000 compliant. In addition, MiningCo will continue
to attempt to obtain verification from all remaining distributors, suppliers and
vendors that their systems are Year 2000 compliant. MiningCo intends to complete
its assessment, and the replacement or remediation of any non-Year 2000
compliant technologies, by the end of the third quarter of 1999.
 
    COSTS.  MiningCo estimates that the total cost for its Year 2000 compliance
efforts will be approximately $250,000. Most of these expenses relate to the
operating costs associated with time spent by employees in Year 2000 compliance
matters. If MiningCo encounters unexpected difficulties, or if it is unable to
obtain compliance information from material third parties, it may need to spend
additional amounts to ensure that its systems are Year 2000 compliant.
 
    RISKS.  Although MiningCo has received compliance information from its
material third-party vendors, it has not received compliance information from
all of its third-party vendors. In addition, it is possible that MiningCo's
third-party vendors were mistaken in certifying that their systems are Year 2000
compliant. In addition, MiningCo will not conduct an end-to-end system test
until the second quarter of 1999. The failure of MiningCo to fix its internal
systems or to fix or replace material third-party software, hardware or services
on a timely basis could result in lost revenues, increased operating costs and
other business interruptions, any of which could have a material adverse effect
on MiningCo's business, results of operations and financial condition. Moreover,
the failure to adequately address Year 2000 compliance issues could result in
claims of mismanagement and related litigation, which would be costly and
time-consuming to defend.
 
    In addition, there can be no assurance that governmental agencies, utility
companies, Internet access companies, third-party service providers and others
outside MiningCo's control will be Year 2000 compliant. The failure by those
entities to be Year 2000 compliant could result in a systemic failure beyond the
control of MiningCo, such as a prolonged Internet, telecommunications or
electrical failure, which could also prevent MiningCo from delivering
MININGCO.COM, decrease the use of the Internet or prevent users from accessing
MININGCO.COM, any of which would have a material adverse effect on MiningCo's
business, results of operations and financial condition.
 
    CONTINGENCY PLAN.  As discussed above, MiningCo is engaged in an ongoing
Year 2000 assessment and has developed no contingency plans to address the
worst-case scenario that might occur if technologies it is dependent upon
actually are not Year 2000 compliant. The results of MiningCo's Year 2000
simulation testing and the responses received from all third-party vendors and
service providers will be taken into account in determining the need for and
nature and extent of any contingency plans. MiningCo intends to develop any
required contingency plan by the end of the second quarter of 1999.
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
    In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use" ("SOP 98-1"), which provides guidance
for determining whether computer software is internal-use software and
accounting for the proceeds of computer software originally developed or
obtained for internal use and then subsequently sold to the public. SOP 98-1
also provides guidance on capitalization of the costs incurred for computer
software developed or obtained for internal use. MiningCo does not expect the
adoption of SOP 98-1 to have a material effect on its capitalization policy.

service. Our service is a network of over 600 web sites, each of which focuses
on a specific topic and is managed by a knowledgeable human guide. Through these
GuideSites, MININGCO.COM provides annotated Internet directories that include
approximately 400,000 pre-screened links to other web sites, enabling users to
quickly find relevant Internet content. The GuideSite network also provides
original high-quality content that is created regularly by the guides on
thousands of subjects. Additionally, our GuideSites provide focused forums
around which organized and moderated online communities develop. We believe that
our service offers an enjoyable and efficient Internet experience for users
across a broad range of topics, creating highly targeted marketing opportunities
for advertisers and for businesses that market their products and services over
the Internet. We believe that over 4.6 million unique users visited MININGCO.COM
in January 1999, making MININGCO.COM the sixth largest news/information/
entertainment Internet property in terms of audience reach and the 26th largest
Internet property overall for that month.
    
 
INDUSTRY BACKGROUND
 
   
    The Internet is a significant and rapidly growing global medium for
collecting and exchanging information, communicating, entertaining and
conducting business. The growth of this medium is being driven by the
development of compelling Internet content, increasing consumer awareness of the
Internet and inexpensive web access. MiningCo believes that the number of
Internet users worldwide exceeded 68 million in 1997 and will grow to over 319
million by 2002.
    
 
   
    INTERNET ADVERTISING AND ELECTRONIC COMMERCE.  Unlike most traditional
media, the Internet allows advertisers to target specific audiences while
tracking impression levels, user demographics and advertisement effectiveness.
MiningCo believes that online advertising revenues will grow from approximately
$940 million in 1997 to approximately $7.7 billion in 2002.
    
 
   
    Since online purchases of goods and services can be less expensive and more
convenient than traditional transactions, the Internet is becoming a powerful
electronic commerce platform. MiningCo believes that as the volume of electronic
commerce transactions expands, retailers will offer a greater variety of
products and services over the Internet. MiningCo believes that the amount of
goods and services purchased in online consumer transactions will grow from
approximately $2.6 billion in 1997 to approximately $37.5 billion in 2002.
    
 
    INTERNET NAVIGATION.  The rapid growth in the amount of information
available on the Internet presents significant challenges for users seeking
specific information and resources. A number of tools have emerged to enable
users to find this information, including Internet directories and search
engines. Internet directories generally list web sites by specific topics of
interest and by their Internet address, thus enabling an interested user to go
directly to the listed site by clicking on the address. However, with the growth
of the amount of content available on the Internet, these directories have
become increasingly difficult to build and maintain with a high level of
quality. Search engines typically use software that searches the Internet to
capture, store and index web site information in order to retrieve web site
listings in response to a query. These software programs have a limited ability
to accurately determine the quality or relevance of the web sites being
referenced. MiningCo believes that, as the Internet grows, the ability of
traditional Internet directories and search engines to provide current and
relevant references is likely to diminish, making these services less useful.
 
    CONTENT.  A vast amount of content is being added to the Internet every day
and the quality of this content varies significantly. MiningCo believes that
higher quality Internet content is typically found
 
                                       27
<PAGE>
on topic-specific sites, and is created by individuals who are knowledgeable
about their topics. Because these sites tend to be widely dispersed, users
generally must visit a number of unaffiliated sites in order to access
high-quality content on more than one topic. MiningCo believes that few Internet
services offer aggregated high-quality content across a wide range of topics.
 
    COMMUNITY.  Internet users often seek organized online communities where
they can interact with individuals who share similar interests and find related
information, products and services. MiningCo believes that few Internet services
provide a broad range of community features. For example, home page services
allow users to create their own web pages and interact with other users, but
often do not provide quality information, products and services. In addition,
home page services often lack paid individuals responsible for monitoring and
organizing the communities.
 
    MiningCo believes that Internet users are seeking Internet navigation that
enables users to efficiently locate relevant information, original content
developed by knowledgeable authors on a broad range of topics and moderated and
organized online communities. In addition, MiningCo believes that Internet
advertisers and electronic commerce marketers are seeking a highly targeted
audience with a propensity to purchase goods and services online.
 
THE MININGCO.COM SOLUTION
 
    MiningCo, through its network of knowledgeable and paid guides, offers
relevant, filtered Internet directories, high-quality original content on
thousands of subjects and hundreds of full-featured online communities. The
guides complete a comprehensive 16-week training process and are monitored for
quality and consistency. MiningCo believes that MININGCO.COM fosters brand
loyalty, repeat usage and increased duration of visits by providing an
enjoyable, efficient Internet experience. The breadth of the GuideSite network
and the focus of each GuideSite on MININGCO.COM provides advertisers and
electronic commerce marketers with highly targeted marketing opportunities
across numerous consumer and business categories.
 
    ENHANCED INTERNET NAVIGATION SERVICE.  MiningCo's network of over 600
GuideSites features annotated Internet directories that include approximately
400,000 links to other web sites. The guides regularly search the Internet to
find relevant content sites, or specific pages within a site, and evaluate their
quality and timeliness, saving the user from this time-consuming and often
frustrating task. In addition to pre-screening and selecting links, the guides
provide concise descriptions of the content on each link, enabling users to
quickly indentify relevant Internet content.
 
    HIGH-QUALITY, AGGREGATED CONTENT.  MiningCo's service provides original
content that is created by the guides on a regular basis. This content includes
features and newsletters. The aggregation of GuideSites allows users to find a
broad range of high-quality content within a single network. MiningCo has
exclusive online rights to all guide-developed content, which enables MiningCo
to increase both MININGCO.COM usage and related revenue opportunities. For
example, MiningCo is able to syndicate this content to other Internet services
to drive traffic to MININGCO.COM. Additionally, MiningCo can use this content to
create promotions for its electronic commerce partners that integrate this
content with content provided by the electronic commerce partner.
 
    RICHER COMMUNITY EXPERIENCE.  MiningCo believes that its GuideSites provide
focused forums around which online communities develop. Each GuideSite includes
a variety of community features that are moderated by the guides, including
bulletin boards, chat and events calendars, as well as quality information,
products and services. MiningCo believes that its knowledgeable and paid guides
maintain high-quality interaction and organization in their communities. Users
may also e-mail guides directly to seek information.
 
                                       28

    TARGETED ADVERTISING AND ELECTRONIC COMMERCE.  MiningCo believes that its
service provides advertisers and electronic commerce marketers with a broad
range of highly targeted marketing opportunities. MiningCo believes that, in
winter 1999, the percentage of MININGCO.COM users that purchased online was
higher than users of leading navigation sites in some of the largest electronic
commerce categories, including books, airline tickets/reservations, computer
hardware, general software, musical CDs/tapes, stocks and mutual funds, event
tickets, home banking software, flowers, Internet software and business
equipment.
    
 
THE MININGCO.COM STRATEGY
 
    MiningCo's objective is to become a primary Internet destination and a
leading Internet advertising and electronic commerce platform. The key elements
of MiningCo's strategy include:
 
    BUILDING BRAND AWARENESS.  MiningCo believes that establishing brand
awareness is critical to attracting and retaining users, advertisers and
electronic commerce partners. In June 1998, MiningCo augmented its online
marketing efforts with the initiation of its first significant offline marketing
campaign. MiningCo intends to build its brand awareness and user traffic by
significantly expanding its marketing efforts, including both offline and online
marketing initiatives. MiningCo also intends to build brand awareness through
distribution and syndication partnerships.
 
    INCREASING TRAFFIC THROUGH DISTRIBUTION AND SYNDICATION PARTNERSHIPS.  In
addition to its marketing and brand building initiatives, MiningCo believes that
distribution and syndication partnerships are a valuable way to drive traffic to
MININGCO.COM. Through these partnerships, MiningCo provides content to a
partner's web site, and users can link to MININGCO.COM by clicking on this
content. MiningCo has formed partnerships with Internet service providers such
as AT&T Worldnet, BellSouth.net and Earthlink; content web sites such as CBS
SportsLine and Weather.com; search engines/Internet directories such as
GoTo.com, LookSmart, Metacrawler and Netscape Communications' NetSearch; and
broadband cable-related sites such as AMC American Pop, American Movie Classics,
Bravo, Court TV, Home Box Office, Independent Film Channel, LifetimeTV.com,
Romance Classics and Showtime. MiningCo also intends to enter into relationships
with companies that could provide channel or section content to MiningCo.
MiningCo intends to expand its existing distribution and syndication
partnerships and to develop relationships with additional partners in the
future.
 
    INCREASING USAGE OF MININGCO.COM.  MiningCo believes that expanding the
functions, features and content of MININGCO.COM, as well as increasing internal
cross-promotion between GuideSites, will increase user loyalty, repeat usage and
duration per visit. MiningCo plans to further develop its registration and
personalization processes and to introduce programs to convert users to members.
 
    EXPANDING INTERNAL ADVERTISING SALES CAPABILITIES.  MiningCo believes that a
strong internal advertising sales organization is essential to effectively
generate revenues from MININGCO.COM. As of January 31, 1999, MiningCo had an
internal advertising sales staff of nine professionals. To supplement the
efforts of its internal advertising sales staff, MiningCo uses third-party
advertising sales representatives to sell advertisements. MiningCo intends to
significantly increase the size of its internal sales staff in order to maintain
closer relationships with its advertisers and electronic commerce partners, to
optimize its advertising rates and to reduce advertising sales costs as a
percentage of revenues.
 
    CONVERTING TRAFFIC INTO REVENUES.  MiningCo's service is designed to offer a
highly targeted platform for advertisers and electronic commerce partners.
MiningCo intends to increase its advertising revenues by focusing on a number of
key strategies, including broadening its base of advertisers and electronic
commerce partners and optimizing its advertising rates by leveraging the
increasing flow of traffic in highly targeted sections within the GuideSite
network.

    MiningCo has developed a template for consistent presentation of each
GuideSite's navigational features, content and community tools. This template
includes:
 
    - a welcome page that promotes various aspects of a GuideSite, including the
      guide's latest featured article;
 
    - the name, e-mail address and photograph of the guide managing the
      GuideSite;
 
    - an Internet directory that provides annotated links to the guide's
      selected third-party Internet content;
 
    - an archive of the guide's original content features;
 
    - a guide-created e-mail newsletter to allow GuideSite users to stay in
      touch with developments on the GuideSite and the GuideSite's topic;
 
    - a guide-moderated bulletin board where visitors can post questions,
      opinions or information;
 
    - a chat room for visitors that is used for regularly scheduled,
      guide-hosted chat sessions and unscheduled open chat;
 
    - an events calendar maintained by the guide that lists various activities
      and events related to the GuideSite's topic;
 
    - a guide biography page that provides users with background information
      regarding the guide; and
 
    - a feedback form for users to submit comments directly to the guide
      regarding a particular GuideSite.
 
In order to receive e-mail newsletters and to access GuideSite bulletin boards
and chat rooms, users first register with MININGCO.COM by providing basic
information.
 
    MiningCo's editors regularly identify noteworthy content features within the
GuideSites, and combine this content in a variety of formats for users. This
content is used to create daily features on pages within MININGCO.COM (e.g.,
"MININGCO TODAY"), and to develop e-mail newsletters. MiningCo believes that
these features and newsletters are effective site promotion and user retention
tools.
 
DISTRIBUTION AND SYNDICATION PARTNERSHIPS
 
    MiningCo believes that its distribution and syndication partnerships drive
traffic to MININGCO.COM. Through these partnerships, MiningCo provides content
to a partner's web site, and users can link to MININGCO.COM by clicking on the
content. The flexibility and breadth of MiningCo's content enables it to partner
with a broad range of Internet companies, including Internet service providers,
content web sites, search engines/Internet directories and broadband
cable-related sites. MiningCo has agreements to provide content to some of the
leading Internet service providers, such as AT&T WorldNet, BellSouth.net and
EarthLink. Additionally, MiningCo provides content to popular content web sites
such as CBS SportsLine and Weather.com. MiningCo also currently has agreements
with search engines/Internet directories such as GoTo.com, LookSmart,
Metacrawler and Netscape Communications' NetSearch. MiningCo also has agreements
with broadband cable-related sites such as AMC American Pop, American Movie
Classics, Bravo, Court TV, LifetimeTV.com, Home Box Office, Independent Film
Channel, Romance Classics and Showtime. These agreements typically require
MiningCo to make payments that are either fixed or are based on the amount of
user traffic directed from the partner's site to MININGCO.COM. In some
instances, MiningCo will display a partner's logo and/or color scheme to users
who are directed to MININGCO.COM by that partner.

ADVERTISING AND ELECTRONIC COMMERCE RELATIONSHIPS
 
    MiningCo believes its service provides a highly targeted platform for
advertisers and electronic commerce partners over a broad range of consumer and
business categories. To date, sales of advertisements on MININGCO.COM have been
generated primarily by MiningCo's internal advertising sales organization and,
to a lesser extent, by third-party advertising sales representatives. As of
January 31, 1999, MiningCo had an internal advertising sales organization
consisting of nine professionals, located in New York, Los Angeles and San
Francisco. MiningCo intends to significantly increase the size of its internal
advertising sales organization. MiningCo's internal advertising sales force
maintains close relationships with advertisers by consulting regularly with them
on design and placement of their Internet-based advertising, by providing them
with advertising measurement analysis and by providing a high level of customer
support. MiningCo's agreements with its third-party advertising sales
representatives are generally terminable by either party with 90 days' prior
written notice.
 
    MiningCo's advertisers enter into short-term agreements, typically one to
three months, under which they generally receive a guaranteed number of
impressions for a fixed fee. MiningCo's agreements with its electronic commerce
partners are typically longer in length, ranging from six months to two years
and, in particular cases, these agreements entitle MiningCo to a share of
revenues generated by sales of merchandise or services over a particular
threshold resulting from direct links from MININGCO.COM. Advertisers and
electronic commerce partners have significant flexibility in determining the
placement of their advertisements based on the level of targeting they want to
achieve. MiningCo offers advertisers and electronic commerce partners numerous
sizes and types of advertising placement, including banner advertisements,
button advertisements and text links. MiningCo also offers sponsorship programs
and other promotional opportunities to build brand awareness and to drive
traffic to the web sites of its advertisers and electronic commerce partners.
 
    ADVERTISING CUSTOMERS.  The following is a list of some of the advertisers
that advertised on MININGCO.COM during 1998:
 
    -  @Hand
 
    -  Auction Universe
 
    -  Bid.com
 
    -  Bell Atlantic's Big Yellow
 
    -  Citibank
 
    -  Dow Jones Interactive
 
    -  eBay
 
    -  HomeShark
 
    -  House.net
 
    -  IBM
 
    -  Intellipost
 
    -  Schering-Plough
 
    -  Tripod
 
    -  ValuPage
 
    -  Ziff Davis' ZD University
 
    ELECTRONIC COMMERCE PARTNERS.  As of January 31, 1999, MiningCo had
electronic commerce partnerships with the following entities:
 
    -  Bertelsmann Music Group (Music CD's)
 
    -  Beyond.com (Software)
 
    -  BigStar Entertainment (Videos)
 
    -  Buy.com (Computer hardware)
 
    -  iVillage (Baby supplies through iBaby)
 
    -  LowestFare.com (Travel)
 
    -  Office Max (Office supplies)
 
    -  Trading Direct (Online brokerage)
 
                                       32
<PAGE>
    MiningCo leverages its content to facilitate online sales of merchandise and
services. For several of its electronic commerce partners, MiningCo has
developed promotions that integrate original content from MININGCO.COM with
traditional commercial advertising. MiningCo provides links to these integrated
promotional web sites by prominently displaying an electronic commerce partner's
advertisement within MININGCO.COM. For example, MiningCo has developed an online
video store for BigStar that integrates BigStar's video offerings with movie
reviews independently written by MININGCO.COM guides. As part of this promotion,
guides can make recommendations for movies related to their GuideSites' topics
that are linked to the BigStar video store. As of December 31, 1998, over 130
guides had created annotated links to BigStar's video store within their
GuideSites. MiningCo believes these features create a more relevant, engaging
purchasing vehicle for users, while enhancing the value of MiningCo's service as
an electronic commerce platform.
 
MARKETING AND BRAND PROMOTION
 
    MiningCo believes that an aggressive brand promotion campaign will increase
usage of MININGCO.COM, as well as attract additional advertisers and electronic
commerce partners. MiningCo markets its service through online advertising. In
addition, MiningCo has been advertising in selected cities through traditional
offline media, including outdoor and radio advertisements, and a national trade
magazine campaign. MiningCo also utilizes public relations, trade shows and
ongoing customer communications programs. MiningCo intends to expand its
marketing and brand promotion initiatives.
 
THE GUIDE RELATIONSHIP
 
    As of January 31, 1999, MiningCo's 605 guides, 333 of which had been guides
for at least one year, were located in over 40 states and 18 countries. Through
the GuideSites, these independent contractors create annotated Internet
directories and original content, and moderate community tools such as bulletin
boards and chat.
 
    APPLICATION AND TRAINING.  MiningCo recruits its guides through various
methods, including searches of the Internet for topic-specific web sites run by
individuals, MININGCO.COM user inquiries, referrals by existing guides and
Internet-based classified job listings. Guide applications are available on
MININGCO.COM and are screened by a team of editors who read and evaluate the
applicant's sample feature and Internet directories, as well as assess the
applicant's knowledge of his or her topic. Once an application is accepted, the
applicant becomes an associate guide and is placed into a four-week preliminary
training class. During this period, the associate guide is taught how to
construct and maintain a GuideSite, how to administer a bulletin board and chat,
and how to create features and newsletters. At the same time, MiningCo reviews
the associate guide's feature articles and directories for quality of
organization, annotation, completeness, direct linking to relevant pages within
web sites and writing skills. If the associate guide meets certain qualification
criteria at the end of this period, his or her web site becomes a live GuideSite
and the associate guide becomes a guide.
 
    Following successful completion of the training class, each guide is placed
in a comprehensive 12-week follow-on training and quality control process.
During this period, the editorial staff provides guides with feedback on the
strengths and weaknesses of their GuideSites and makes recommendations for
further improvements of both quality and consistency. At the end of this 12-week
period, the quality of the GuideSite is rated. This rating is regularly
revisited by the editors and is one of the factors that determines a guide's
minimum compensation.
 
    GUIDE CONTRACTS.  Pursuant to the standard guide contract, MiningCo is
granted an exclusive perpetual license to use guide-developed MININGCO.COM
content on the Internet and on any other commercial online service, subject to
the guide sharing in any associated revenue. In addition, MiningCo also retains
the right, on a non-exclusive basis, to use the content in any offline media,
subject to the guide sharing in any associated revenue. The guides have agreed
to share with MiningCo
 
                                       33
<PAGE>
any revenue derived from the guide's use of this content in any offline media.
The standard guide contract is terminable by either party upon 15 days' prior
written notice.
 
    GUIDE COMPENSATION.  Guides are currently compensated based on the greater
of a monthly guarantee or a percentage of net advertising revenues generated by
all of the GuideSites on MININGCO.COM, which is distributed among the guides
based on the user traffic on each guide's respective GuideSite. By compensating
guides based on the net advertising revenues of all of the GuideSites, the
guides are provided incentives to help and encourage each other. Guides are also
currently entitled to share a percentage of net transaction revenues and net
syndication revenues. In addition, MiningCo may distribute a discretionary bonus
to guides based on outstanding content, exceptional performance and longevity.
Upon the closing of this offering, MiningCo intends to grant non-qualified stock
options to a significant majority of its guides to purchase up to an aggregate
of 200,000 shares of common stock at an exercise price per share equal to the
initial public offering price.
 
    EDITORIAL PROCEDURES.  The guides are directly supported by a team of 35
MiningCo employees, including 22 editors. Editors regularly monitor each
GuideSite to assess the relevance and quality of features, the management of
community tools and compliance with MiningCo policies. Editors also provide
weekly newsletters and host chats with guides to better communicate GuideSite
tips, including news, ideas for improving sites and marketing information.
 
    ONLINE GUIDE LOUNGE.  MiningCo provides relevant information to the guides
through a password-protected web site and via bulletin boards, chat and
newsletters. The guide lounge includes a library of reference information for
the guides, including MiningCo policies, publishing regulations and other useful
information. The guide lounge also enables guides to become members of their own
community.
 
OPERATING INFRASTRUCTURE
 
    MININGCO.COM's operating infrastructure is designed to provide timely and
efficient delivery of the service to users. In response to end-user requests,
each page on a GuideSite is generated and delivered by one of MiningCo's web and
applications servers. MiningCo's service uses Microsoft Windows NT and Sun
Solaris as operating systems, and Microsoft's Internet Index Server and
Netscape's Enterprise Web server software. MININGCO.COM's functions integrate
commercial and company-developed software. All of MiningCo's internally
developed applications utilize Active Server Page technology, and many interact
with various third-party applications licensed by MiningCo, including
Microsoft's Internet Index Server search function, Microsoft's SQL Server
database software, Proxicom's Forum Bulletin Board System, Paralogic's Parachat
and L-Soft's Listserv for e-mail newsletters. MiningCo intends to add to its
serving and technical capabilities as required to meet usage demands.
 
    The administrative control center is MiningCo's internally developed
Internet-based site management environment. This center enables MiningCo's
guides to remotely manage their GuideSites at any time via a password-protected
interface in order to preview and upload content, view usage and feedback
reports, and access administrative tools for newsletters, chat, bulletin boards
and events calendars.
 
    In March 1998, MiningCo entered into an Internet-hosting agreement with
Frontier to maintain all of MiningCo's production servers at Frontier's
Manhattan Data Center. This agreement terminates on February 1, 2000. Frontier
provides comprehensive facilities management services including human and
technical monitoring of all production servers 24 hours per day, seven days per
week. Frontier provides the means of connectivity for MININGCO.COM's servers to
end-users via the Internet through high capacity transmission wires. These
connections link to many different parts of the Internet via a combination of
public and private peering agreements. The facility has two independent
uninterruptible power supplies, which are battery-powered, as well as two
independent diesel generators designed to provide power to these systems within
seconds of a power outage. The diesel generators can supply the data center's
 
                                       34
<PAGE>
power for nine days before refueling is required. Frontier does not guarantee
that MiningCo's Internet access will be uninterrupted, error-free or secure.
MiningCo's operations are dependent on Frontier's ability to protect both
Frontier's and MiningCo's systems against damage from fire, power loss, water
damage, telecommunications failures, vandalism and other malicious acts, and
similar unexpected adverse events. Any disruption in the Internet access
provided by Frontier could have a material adverse effect on MiningCo's
business, results of operations and financial condition.
 
    MININGCO.COM must accommodate a high volume of traffic and MININGCO.COM has
in the past and may in the future experience slower response times and system
downtime for a variety of reasons. An increase in volume of users accessing
MININGCO.COM could lead to systems failures or slower response times and
adversely affect advertising revenues. Users may become dissatisfied by any
system failure that interrupts MiningCo's ability to provide MININGCO.COM to
them or results in slower response time. MININGCO.COM could also be affected by
computer viruses, electronic break-ins or other similar disruptions. MiningCo's
insurance policies have low coverage limits and therefore insurance may not
adequately compensate MiningCo for any losses that may occur due to any failures
in its system or interruptions in its service. MiningCo is in the process of
developing a comprehensive disaster recovery plan to respond to system failures.
MiningCo's business, results of operations and financial condition could be
materially adversely affected by any damage or failure that interrupts or delays
its operations.
 
    All of MiningCo's production data is copied to backup tapes each night and
these backup tapes are rotated to a third-party facility for off-site storage.
MiningCo keeps all of its production servers behind packet-filtered routers and
does not allow any outside access to any administrative functions. Strict
password management and physical security measures are followed.
 
    MiningCo's users and guides depend on Internet service providers, online
service providers and other web site operators for access to MININGCO.COM. Each
of these providers and operators has experienced significant outages in the
past, and could experience outages, delays and other difficulties due to system
failures unrelated to MiningCo's systems. Moreover, the Internet infrastructure
may not be able to support continued growth in its use. Any of these problems
could materially adversely affect MiningCo's business, results of operations and
financial condition.
 
GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES
 
    GENERAL.  There is an increasing number of laws and regulations pertaining
to the Internet. In addition, a number of legislative and regulatory proposals
are under consideration by federal, state, local and foreign governments and
agencies. Laws or regulations may be adopted with respect to the Internet
relating to liability for information retrieved from or transmitted over the
Internet, online content regulation, user privacy, taxation and quality of
products and services. Moreover, the applicability to the Internet of existing
laws governing issues such as intellectual property ownership and infringement,
copyright, trademark, trade secret, obscenity, libel, employment and personal
privacy is uncertain and developing. Any new legislation or regulation, or the
application or interpretation of existing laws, may decrease the growth in the
use of the Internet, which could in turn decrease the demand for MiningCo's
service, increase MiningCo's cost of doing business or otherwise have a material
adverse effect on MiningCo's business, results of operations and financial
condition.
 
    LIABILITY FOR INFORMATION RETRIEVED FROM MININGCO.COM AND FROM THE
INTERNET.  Content may be accessed on MININGCO.COM or on the web sites of
MiningCo's distribution partners, and this content may be downloaded by users
and subsequently transmitted to others over the Internet. This could result in
claims against MiningCo based on a variety of theories, including defamation,
obscenity, negligence, copyright or trademark infringement or other theories
based on the nature, publication and distribution of this content. These types
of claims have been brought, sometimes successfully, against providers of
Internet services in the past. MiningCo could also be exposed to liability with
respect to third-party content that may be posted by users in chat rooms or
bulletin boards offered on the GuideSites. It is
 
                                       35
<PAGE>
also possible that if any information, including information deemed to
constitute professional advice such as legal, medical, financial or investment
advice, provided on MININGCO.COM contains errors or false or misleading
information, third parties could make claims against MiningCo for losses
incurred in reliance on such information. MININGCO.COM contains approximately
400,000 human-filtered annotated links to other web sites. As a result, MiningCo
may be subject to claims alleging that, by directly or indirectly providing
links to other web sites, MiningCo is liable for copyright or trademark
infringement or the wrongful actions of third parties through their respective
web sites.
 
    The Communications Decency Act of 1996 (the "CDA") was enacted to prohibit
the transmission over the Internet of indecent, obscene or offensive content.
While selected parts of the CDA have been deemed unconstitutional, provisions
protecting providers of Internet services from claims related to third-party
content remain effective. Under the CDA, a provider of Internet services will
generally not be treated as a publisher or speaker of any information available
on its service but provided by a third-party content provider unless the
provider of Internet services exerts editorial control over the content or
embraces the content as its own. MiningCo's activities may prevent it from being
able to take advantage of this safe harbor provision. In particular, while
MiningCo does not edit the guide-developed content prior to its availability on
MININGCO.COM and only monitors this content to ensure compliance with MiningCo's
policies, MiningCo may be subjected to claims that it is the publisher of the
content available on the GuideSites. In addition, since MiningCo has exclusive
online rights to all guide-developed content on MININGCO.COM, it aggregates this
content for use on MININGCO.COM and for syndication and distribution to
third-party web sites and electronic commerce partners. MiningCo may be
subjected to claims that it is the publisher of this aggregated guide-developed
content. While MiningCo attempts to reduce its exposure to this potential
liability through, among other things, provisions in guide agreements, user
policies and disclaimers, the enforceability and effectiveness of such measures
are uncertain.
 
    MiningCo's general liability insurance may not cover all potential claims to
which MiningCo is exposed and may not be adequate to indemnify MiningCo for all
liability that may be imposed. Any imposition of liability that is not covered
by insurance or is in excess of insurance coverage could have a material adverse
effect on MiningCo's business, results of operations and financial condition.
Even to the extent that these claims do not result in liability to MiningCo,
MiningCo could incur significant costs in investigating and defending against
these claims. Potential liability for information disseminated through
MININGCO.COM could lead MiningCo to implement measures to reduce its exposure to
such liability, which may require the expenditure of substantial resources and
limit the attractiveness of MiningCo's service to users.
 
    STATUS OF THE GUIDES AS INDEPENDENT CONTRACTORS.  MiningCo treats the guides
as independent contractors for tax and employee benefit purposes. One or more
jurisdictions may deem the guides to be employees of MiningCo rather than
independent contractors and seek to impose taxes, interest and penalties to
MiningCo. MiningCo could have substantial tax and employee benefit liabilities
if it were ultimately determined that the guides are employees of MiningCo. See
"Risks Factors--We could incur significant withholding taxes and employee
benefits expenses if the guides were deemed to be our employees rather than
independent contractors."
 
    ONLINE CONTENT REGULATIONS.  Several federal and state statutes prohibit the
transmission of indecent, obscene or offensive content over the Internet to
particular groups of persons. In addition, pending legislation seeks to ban
Internet gambling and federal and state officials have taken action against
businesses that operate Internet gambling activities. The enforcement of these
statutes and initiatives, and any future enforcement activities, statutes and
initiatives, may result in limitations on the type of content and advertisements
available on MININGCO.COM. Legislation regulating online content could dampen
the growth in use of the Internet generally and decrease the acceptance of the
Internet as an advertising and electronic commerce medium, which could have a
material adverse effect on MiningCo's business, results of operations and
financial condition.
 
                                       36

    PRIVACY CONCERNS.  The Federal Trade Commission is considering adopting
regulations regarding the collection and use of personal identifying information
obtained from individuals when accessing web sites, with particular emphasis on
access by minors. These regulations may include requirements that companies
establish certain procedures to, among other things:
 
    - give adequate notice to consumers regarding information collection and
      disclosure practices;
 
    - provide consumers with the ability to have personal identifying
      information deleted from a company's database;
 
    - provide consumers with access to their personal information and with the
      ability to rectify inaccurate information;
 
    - clearly identify affiliations or a lack thereof with third parties that
      may collect information or sponsor activities on a company's web site; and
 
    - obtain express parental consent prior to collecting and using personal
      identifying information obtained from children under 13 years of age.
 
These regulations may also include enforcement and redress provisions. While
MiningCo is implementing programs designed to enhance the protection of the
privacy of its users, including children, there can be no assurance that these
programs will conform with any regulations adopted by the FTC. Moreover, even in
the absence of those regulations, the FTC has begun investigations into the
privacy practices of companies that collect information on the Internet. One
investigation resulted in a consent decree pursuant to which an Internet company
agreed to establish programs to implement the principles noted above. MiningCo
may become subject to a similar investigation, or the FTC's regulatory and
enforcement efforts may adversely affect the ability to collect demographic and
personal information from users, which could have an adverse effect on
MiningCo's ability to provide highly targeted opportunities for advertisers and
electronic commerce marketers. Any of these developments would have a material
adverse effect on MiningCo's business, results of operations and financial
condition.
 
    It is also possible that cookies, or information keyed to a specific server,
file pathway or directory location that is stored on a user's hard drive,
possibly without the user's knowledge, which are used to track demographic
information and to target advertising, may become subject to laws limiting or
prohibiting their use. A number of Internet commentators, advocates and
governmental bodies in the United States and other countries have urged the
passage of laws limiting or abolishing the use of cookies. Limitations on or
elimination of MiningCo's use of cookies could limit the effectiveness of
MiningCo's targeting of advertisements, which could have a material adverse
effect on MiningCo's business, results of operations and financial condition.
 
    The European Union has adopted a directive that imposes restrictions on the
collection and use of personal data. Under the directive, EU citizens are
guaranteed rights to access their data, rights to know where the data
originated, rights to have inaccurate data rectified, rights to recourse in the
event of unlawful processing and rights to withhold permission to use their data
for direct marketing. The directive could, among other things, affect U.S.
companies that collect information over the Internet from individuals in EU
member countries, and may impose restrictions that are more stringent than
current Internet privacy standard in the United States. In particular, companies
with offices located in EU countries will not be allowed to send personal
information to countries that do not maintain adequate standards of privacy. The
directive does not, however, define what standards of privacy are adequate. As a
result, the directive may adversely affect the activities of entities such as
MiningCo that engage in data collection from users in EU member countries.
 
    DATA PROTECTION.  Legislative proposals have been made by the federal
government that would afford broader protection to owners of databases of
information such as stock quotes and sports scores.
 
                                       37
<PAGE>
This protection already exists in the EU. If enacted, this legislation could
result in an increase in the price of services that provide data to web sites
and could create potential liability for unauthorized use of this data. Either
of these possibilities could have a material adverse effect on MiningCo's
business, results of operations and financial condition.
 
    INTERNET TAXATION.  A number of legislative proposals have been made at the
federal, state and local level, and by certain foreign governments, that would
impose additional taxes on the sale of goods and services over the Internet and
certain states have taken measures to tax Internet-related activities. Although
Congress recently placed a three-year moratorium on state and local taxes on
Internet access or on discriminatory taxes on electronic commerce, existing
state or local laws were expressly excepted from this moratorium. Further, once
this moratorium is lifted, some type of federal and/or state taxes may be
imposed upon Internet commerce. This legislation, or other attempts at
regulating commerce over the Internet, may substantially impede the growth of
commerce on the Internet and, as a result, adversely affect MiningCo's
opportunity to derive financial benefit from those activities.
 
    ARRANGEMENTS WITH ELECTRONIC COMMERCE PARTNERS.  MiningCo enters into
agreements with certain electronic commerce partners under which MiningCo may be
entitled to receive a share of certain revenue generated from the purchase of
goods and services through direct links from MININGCO.COM. These agreements may
expose MiningCo to additional legal risks and uncertainties, including potential
liabilities to consumers of those products and services by virtue of MiningCo's
involvement in providing access to those products or services, even if MiningCo
does not itself provide those products or services. Any indemnification provided
to MiningCo in its agreements with these parties, if available, may not be
adequate.
 
    DOMAIN NAMES.  Domain names are the user's Internet "addresses." The current
system for registering, allocating and managing domain names has been the
subject of litigation, including trademark litigation, and of proposed
regulatory reform. MiningCo has registered the domain name "MININGCO.COM."
Although MiningCo is seeking to register "MININGCO.COM" as a trademark in the
United States, it may not successfully obtain the registration and third parties
may bring claims for infringement against MiningCo for the use of this
trademark. There can be no assurance that MiningCo's domain names will not lose
their value, or that MiningCo will not have to obtain entirely new domain names
in addition to or in lieu of its current domain names if reform efforts result
in a restructuring in the current system.
 
    JURISDICTIONS.  Due to the global nature of the Internet, it is possible
that, although transmissions by MiningCo over the Internet originate primarily
in New York, the governments of other states and foreign countries might attempt
to regulate MiningCo's transmissions or prosecute MiningCo for violations of
their laws. These laws may be modified, or new laws enacted, in the future. Any
of the foregoing developments could have a material adverse effect on MiningCo's
business, results of operations and financial condition. In addition, as
MiningCo's service is available over the Internet in multiple states and foreign
countries, these jurisdictions may claim that MiningCo is required to qualify to
do business as a foreign corporation in each of these states or foreign
countries. MiningCo is qualified to do business only in California and New York,
and failure by MiningCo to qualify as a foreign corporation in a jurisdiction
where it is required to do so could subject MiningCo to taxes and penalties and
could result in the inability of MiningCo to enforce contracts in these
jurisdictions. Any new legislation or regulation, the application of laws and
regulations from jurisdictions whose laws do not currently apply to MiningCo's
business, or the application of existing laws and regulations to the Internet
and other online services could have a material adverse effect on MiningCo's
business, results of operations and financial condition.
 
                                       38
<PAGE>
INTELLECTUAL PROPERTY
 
    MiningCo seeks to protect its proprietary rights, but its actions may be
inadequate to protect its patents, trademarks or other proprietary rights or to
prevent others from claiming violations of their proprietary rights. MiningCo
has one United States patent pending, four patent applications on file with the
United States Patent and Trademark Office and one international patent
application. MiningCo enters into confidentiality agreements with its material
employees, guides, consultants and strategic partners, and generally controls
access to and distribution of its proprietary information. Despite MiningCo's
efforts to protect its proprietary rights from unauthorized use or disclosure,
parties may attempt to disclose, obtain or use its proprietary information. The
steps MiningCo has taken may not prevent misappropriation of its proprietary
information. Third parties may infringe or misappropriate MiningCo's proprietary
rights, which could have a material adverse affect on MiningCo's business,
results of operations and financial condition. The validity, enforceability and
scope of protection of proprietary rights in Internet-related industries is
uncertain and still evolving.
 
    Furthermore, third parties may assert infringement claims against MiningCo.
From time to time MiningCo has been, and MiningCo expects to continue to be,
subject to claims in the ordinary course of its business, including claims of
alleged infringement of the trademarks and other intellectual property rights of
third parties by MiningCo or its guides. These claims and any resultant
litigation, should it occur, could subject MiningCo to significant liability for
damages and could result in the invalidation of MiningCo's proprietary rights.
In addition, even if MiningCo prevails, any litigation could be time-consuming
and expensive to defend, and could result in the diversion of management's time
and attention, any of which could materially adversely affect MiningCo's
business, results of operations and financial condition. Any claims from third
parties may also result in limitations on MiningCo's ability to use the
trademarks and other intellectual property subject to those claims unless
MiningCo enters into agreements with the third parties responsible for those
claims, which may be unavailable on commercially reasonable terms.
 
COMPETITION
 
    MiningCo competes for users, advertisers and electronic commerce marketers
with the following:
 
    - Internet retrieval companies, search engines and other Internet "portal"
      companies (such as Excite, InfoSeek, Lycos and Yahoo!);
 
    - online content web sites (such as C--net, ESPN.com and ZDNet.com);
 
    - online community web sites (such as iVillage);
 
    - online personal homepage services (such as GeoCities and theglobe.com);
 
    - publishers and distributors of television, radio and print (such as CBS,
      Disney, NBC and Time Warner);
 
    - general purpose consumer online services (such as America Online and
      Microsoft Network); and
 
    - web sites maintained by Internet service providers (such as AT&T WorldNet,
      EarthLink and MindSpring).
 
    MiningCo believes that its ability to compete depends on many factors, many
of which are outside of its control. These factors include the quality of
content provided by MiningCo and its competitors, the ease of use of services
developed either by MiningCo or its competitors, the timing and market
acceptance of new and enhanced services developed either by MiningCo or its
competitors, and sales and marketing efforts of MiningCo and its competitors.
 
    MiningCo also competes with television, radio, cable and print (traditional
advertising media) for a share of advertisers' total advertising budgets. If
advertisers perceive the Internet or MININGCO.COM to be
 
                                       39
<PAGE>
a limited or ineffective advertising medium, advertisers may be reluctant to
devote a significant portion of their advertising budget to Internet advertising
or to advertise on MININGCO.COM.
 
    Please see "Risk Factors--We may not be able to compete successfully" for a
more detailed description of the risks of competition to MiningCo.
 
EMPLOYEES AND GUIDES
 
    As of January 31, 1999, MiningCo had 113 full-time employees, including 27
in marketing and sales, 35 in editorial and guide support, 12 in finance and
administration and 39 in product development, operations and technical support.
As of January 31, 1999, MiningCo had 605 guides and an additional 91 guides in
training. None of the guides are employed by MiningCo, but rather they are
engaged by MiningCo as independent contractors. None of MiningCo's employees are
represented by a union. MiningCo believes its relationship with its employees
and the guides is good.
 
FACILITIES
 
    MiningCo's headquarters are currently located in a leased facility in New
York City, consisting of approximately 12,000 square feet of office space that
is under a four-year lease with two years remaining. Annual rental payments
under this lease during 1998 was approximately $285,000, which amount is subject
to annual increases. MiningCo also entered into a six-month lease for
approximately 3,000 square feet of commercial space in Westchester, New York.
MiningCo believes that additional space will be available on commercially
acceptable terms.
 
LEGAL PROCEEDINGS
 
    MiningCo is not a party to any material legal proceedings.

(2) There was no public market for the common stock during 1998. For purposes of

(3) Amounts in these columns represent hypothetical gains that could be achieved
    for the respective options if exercised at the end of the option term. The
    0%, 5% and 10% assumed annual rates of compounded stock price appreciation
    are mandated by rules of the SEC and do not represent MiningCo's estimate or
    projection of MiningCo's future common stock prices. Actual gains, if any,
    on stock option exercises depend on MiningCo's future performance and
    overall stock market conditions. The amounts reflected in the table may be
    more or less than the amounts actually achieved.
 
AGGREGATED OPTION EXERCISES IN THE YEAR ENDED DECEMBER 31, 1998 AND YEAR-END
  OPTION VALUES
 
    The following table sets forth information concerning the value realized
upon exercise of options during 1998 and the number and value of unexercised
options held by each of the named executive officers at December 31, 1998. There
was no public trading market for the common stock as of December 31, 1998.
Accordingly, the values set forth below have been calculated on the basis of the
assumed initial public offering price of $13.00 per share, less the applicable
exercise price per share, multiplied by the number of shares underlying the
options.

(1) Solely for purposes of this calculation, the fair market value of the common
    stock at the time of the exercise was deemed to be the assumed initial
    public offering price of $13.00 per share. The exercise price of the options
    was $0.51 per share.
 
(2) Options to purchase 62,300 shares of common stock will accelerate and become
    exercisable when this offering closes. This will result in an increase in
    the value of Mr. Day's unexercised in-the-money exercisable options of
    $778,127.
 
(3) Options to purchase 53,400 shares of common stock will accelerate and become
    exercisable when this offering closes. This will result in an increase in
    the value of Mr. Wragg's unexercised in-the-money exercisable options of
    $666,966.
 
AMENDED AND RESTATED 1998 STOCK OPTION/STOCK ISSUANCE PLAN
 
   
    MiningCo's amended and restated 1998 stock option/stock issuance plan serves
as the successor equity incentive program to MiningCo's 1997 employee incentive
stock option plan. The 1998 stock option/stock issuance plan became effective on
July 2, 1998 upon adoption by the board of directors and was approved by the
stockholders on the same day. On February 1, 1999 the board approved the amended
and restated 1998 stock option/stock issuance plan, which was approved by the
stockholders on the same day. 1,886,800 shares of common stock were initially
authorized for issuance under the stock option plan. This initial share reserve
was comprised of the shares that remained available for issuance under the old
stock option plan on the effective date of the new stock option plan, including
the shares subject to outstanding options under that plan plus an increase of
890,000 shares. On February 5, 1999, the board authorized, and the stockholders
approved, an increase of 1,338,085 shares. Outstanding options under the old
stock option plan were incorporated into the new stock option plan upon the date
of the approval of the new stock option plan, and no further option grants are
being made under the old stock option plan. The incorporated options will
continue to be governed by their existing terms, unless the plan administrator
elects to extend one or more features of the new stock option plan to those
options.
    
 
                                       47
<PAGE>
    As of the date of this prospectus, there are outstanding options to purchase
a total of 2,075,267 shares of common stock under the new stock option plan, of
which options to purchase 508,222 shares are currently exercisable. Of the
options to purchase 1,567,045 shares of common stock that are not currently
exercisable, the options to purchase 372,936 shares of common stock, with a
weighted average exercise price of $0.51 per share, originally granted under the
old stock option plan shall immediately vest and become exercisable upon the
closing of this offering. Since MiningCo intends to file a registration
statement on Form S-8 as soon as practicable following the closing of this
offering, any shares issued upon exercise of these options will be immediately
available for sale in the public market, subject to the terms of lock-up
agreements entered into between substantially all of these optionholders and the
underwriters.
 
    Except as otherwise noted in the previous paragraph or below, the
outstanding options under the old stock option plan contain substantially the
same terms and conditions summarized below for the discretionary option grant
program in effect under the new stock option plan. The new stock option plan is
divided into three separate components:
 
    - the discretionary option grant program under which eligible individuals in
      MiningCo's employ or service (including officers, non-employee members of
      the board of directors, consultants and guides) may, at the discretion of
      the plan administrator, be granted options to purchase shares of common
      stock at an exercise price determined by the plan administrator;
 
    - the stock issuance program under which those individuals may, in the plan
      administrator's discretion, be issued shares of common stock directly,
      through the purchase of those shares at a price determined by the plan
      administrator or as a bonus tied to the performance of services; and
 
    - the automatic option grant program under which option grants will
      automatically be made at periodic intervals to eligible non-employee
      members of the board of directors to purchase shares of common stock at an
      exercise price equal to 100% of the fair market value of those shares on
      the grant date.
 
    In no event may any one participant in the new stock option plan receive
option grants or direct stock issuances for more than 267,000 shares in the
aggregate per calendar year. Under the old stock option plan, only employees
were eligible to receive option grants and the exercise price could not be less
than the fair market value per share on the grant date.
 
    The discretionary option grant program and the stock issuance program are
administered by the compensation committee of the board of directors. The
compensation committee as plan Administrator has complete discretion to
determine which eligible individuals are to receive option grants or stock
issuances, the time or times when option grants or stock issuances are to be
made, the number of shares subject to each grant or issuance, the status of any
granted option as either an incentive stock option or a non-statutory stock
option under the Federal tax laws, the vesting schedule to be in effect for the
option grant or stock issuance and the maximum term for which any granted option
is to remain outstanding. The administration of the automatic option grant
program is self-executing in accordance with the express provisions of that
program. Under the old stock option plan, only incentive stock options were
granted.
 
    The exercise price for the shares of common stock subject to option grants
made under the new stock option plan may be paid in cash or in shares of common
stock valued at fair market value on the exercise date. The option may also be
exercised through a same-day sale program without any cash outlay by the
optionee. In addition, the plan administrator may provide financial assistance
to one or more participants in the new stock option plan in connection with
their acquisition of shares, by allowing those individuals to deliver a
full-recourse, interest-bearing promissory note in payment of the option
exercise price and any associated withholding taxes incurred in connection with
that acquisition.

    In the event of an acquisition of MiningCo, whether by merger or asset sale
or a sale by the stockholders of more than 50% of the total voting power of
MiningCo that is recommended by the board of directors, each outstanding option
under the discretionary option grant program which is not to be assumed by the
successor corporation or otherwise continued will automatically accelerate in
full, and all repurchase rights relating to shares under the discretionary
option grant program and stock issuance program will immediately lapse, except
to the extent MiningCo's repurchase rights with respect to those shares are to
be assigned to the successor corporation or otherwise continued in effect. Under
the stock option plan, the plan administrator has the authority at the time of
grant to provide that the shares subject to options granted under the
discretionary option grant program will automatically vest:
 
    - upon an acquisition of MiningCo whether or not those options are assumed
      or continued, or
 
    - upon a hostile change in control of MiningCo effected through:
 
       - a tender offer for more than 50% of MiningCo's outstanding voting
         stock, or
 
       - a proxy contest for the election of the board of directors, or
 
       - if the individual is terminated involuntarily or resigns for good
         reason within 12 months following an acquisition in which the
         individual's options were assumed or otherwise continued in effect or
         following a hostile change in control.
 
The vesting of outstanding shares under the stock issuance program may be
accelerated upon similar terms and conditions. In addition, all outstanding
options under MiningCo's old stock option plan will be exercisable upon the
closing of this offering.
 
    Stock appreciation rights are authorized for issuance under the
discretionary option grant program, which rights provide the holders with the
election to surrender their outstanding options for an appreciation distribution
from MiningCo equal to the excess of the fair market value of the vested shares
of common stock subject to the surrendered option over the aggregate exercise
price payable for those shares. This appreciation distribution may be made in
cash or in shares of common stock. There are currently no outstanding stock
appreciation rights.
 
    The plan administrator has the authority to effect the cancellation of
outstanding options under the discretionary option grant program (including
options incorporated from the old stock option plan) in return for the grant of
new options for the same or different number of option shares with an exercise
price per share based upon the fair market value of the common stock on the new
grant date.
 
    Under the automatic option grant program, non-employee board of directors
members will be entitled to receive option grants. Each automatic grant will
have an exercise price equal to the fair market value per share of common stock
on the grant date and will have a maximum term of 10 years, subject to earlier
termination following the optionee's cessation of board of directors service.
Each automatic option will be immediately exercisable; however, any shares
purchased upon exercise of the option will be subject to repurchase, at the
option exercise price paid per share, should the optionee's service as a
non-employee member of the board of directors cease prior to vesting in the
shares. Each 20,000-share grant will vest in four equal and successive annual
installments over the optionee's period of board of director service. Each
annual 5,000-share grant will vest upon the optionee's completion of one year of
board of directors service measured from the grant date. However, each
outstanding option will immediately vest upon changes in control of MiningCo or
the death or disability of the optionee while serving as a board of directors
member. Please see "--Director Compensation."
 
    The board of directors may amend or modify the stock option plan at any
time, subject to any required stockholder approval. The stock option plan will
terminate on the earliest of:
 
    - July 1, 2008
 
                                       49

    - the date on which all shares available for issuance under the stock option
      plan have been issued as fully-vested shares
 
    - the termination of all outstanding options in connection with particular
      changes in control or ownership of MiningCo
 
1999 EMPLOYEE STOCK PURCHASE PLAN
 
    MiningCo's employee stock purchase plan will become effective when the
underwriting agreement for this offering is executed. The purchase plan is
designed to allow eligible employees of MiningCo and participating subsidiaries
to purchase shares of common stock, at semi-annual intervals, through their
periodic payroll deductions. 125,000 shares of common stock have been reserved
for issuance under the purchase plan.
 
    The purchase plan will be implemented in a series of successive purchase
periods, each with a duration of six months. Purchase periods will generally run
from the first business day in May to the last business day in October each year
and from the first business day in November to the last business day in April
the next year. However, the initial purchase period will begin on the
underwriting agreement's execution date and will end on October 31, 1999.
 
    Employees who are scheduled to work more than 20 hours per week for more
than five calendar months per year on the start date of any purchase period are
eligible to enter the purchase plan on that start date.
 
    Payroll deductions may not exceed 15% of the participant's cash earnings.
The accumulated payroll deductions of each participant will be applied to the
purchase of shares on the participant's behalf on each purchase date. The
purchase price per share will equal 85% of the lower of the fair market value of
the common stock on the start of the purchase period or the fair market value on
the purchase date. No participant may purchase more than 500 shares on any
purchase date.
 
    In the event MiningCo is acquired by merger or asset sale, all outstanding
purchase rights will automatically be exercised immediately prior to the
effective date of the acquisition. The purchase price will be equal to 85% of
the lower of the fair market value per share of common stock on the start of the
purchase period in which that acquisition occurs or the fair market value per
share of common stock immediately prior to the acquisition.
 
    The purchase plan will terminate on the earliest of:
 
    - October 31, 2009
 
    - the date on which all shares available for issuance under the purchase
      plan have been sold in accordance with the purchase plan
 
    - the date on which all purchase rights are exercised in connection with an
      acquisition of MiningCo by merger or asset sale
 
    Subject to stockholder approval for certain amendments, the board of
directors may at any time alter, suspend or discontinue the purchase plan.

    Between March 1997 and January 1998, MiningCo issued convertible promissory
notes in an aggregate principal amount of $4,950,000 to a number of investors,
including the investors set forth in the table below. Pursuant to their terms,
the principal amount due on these notes was either automatically convertible
into shares of MiningCo's capital stock upon the closing of the next equity
financing conducted by MiningCo or due and payable on the earlier of the fifth
anniversary of the delivery of the notes or upon an event of default under the
notes. These notes bore interest at a variable rate equal to the prime rate
published by a major financial institution plus 2% per annum. On April 23, 1998,
in consideration for the cancellation of the principal amount of these notes and
$70,000 in interest that accrued on these notes prior to August 12, 1997,
MiningCo issued to the noteholders a total of 3,346,715 shares of Series A
convertible preferred stock. The remaining interest on these notes was evidenced
by newly issued unsecured promissory notes that, by their terms, will be
forgiven and cancelled upon the closing of this offering. Upon the closing of
this offering, the outstanding shares of Series A convertible preferred stock
will convert into a total of 1,191,433 shares of common stock.
    
 
    At the time of the delivery of the convertible promissory notes, MiningCo
issued warrants to purchase a total of 309,748 shares of common stock to the
investors. Of these warrants, warrants to purchase 218,890 shares of common
stock had an exercise price of $0.03 per share and warrants to purchase 90,858

1998, all of the warrants to purchase common stock at an exercise price of $0.03
per share were exercised and warrants to purchase a total of 66,753 shares of
common stock at an exercise price of $4.21 per share were exercised. The
remaining warrant for 24,105 shares was cancelled.

MiningCo and Open Text amended this note to reduce the principal amount
outstanding under this note to $3,255,600. The remaining $650,000 in principal
was evidenced by a newly issued convertible subordinated promissory note that
was subsequently cancelled on April 23, 1998, in consideration for the issuance
of 433,333 shares of Series A convertible preferred stock. None of the
outstanding interest was evidenced by the newly issued convertible subordinated
promissory note. On April 23, 1998, MiningCo and Open Text amended the
 
                                       53
<PAGE>
promissory note to reduce the outstanding principal amount from $3,255,600 to
$1,555,600. This reduction of $1,700,000 in principal, as well as $305,800 of
interest, was simultaneously converted into 1,114,327 shares of Series B
convertible preferred stock. On November 13, 1998, MiningCo issued 913,856
shares of Series C convertible preferred stock in cancellation of the remaining
$1,555,600 in principal and $226,400 in interest outstanding under the
promissory note.
 
    On August 27, 1997, in connection with the execution of the convertible
subordinated promissory note, MiningCo issued Open Text warrants to purchase
24,105 shares of common stock at an exercise price of $4.21 per share. These
warrants were cancelled in December 1998. In January 1998, MiningCo issued Open
Text warrants to purchase 2,670 shares of common stock at an exercise price of
$4.21 per share. In June and July of 1998, MiningCo issued Open Text warrants to
purchase an aggregate of 6,230 shares of common stock at an exercise price of
$4.21 per share. These warrants to purchase an aggregate of 8,900 shares of
common stock remain outstanding.
 
AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT
 
    On April 23, 1998, MiningCo and the purchasers of its Series A convertible
preferred stock and Series B convertible preferred stock entered into an
investors' rights agreement. On November 13, 1998, the investors' rights
agreement was amended and restated to include the purchasers of MiningCo's
Series C convertible preferred stock. Under the terms of the amended and
restated investors' rights agreement, holders of MiningCo's Series A convertible
preferred stock, Series B convertible preferred stock and Series C convertible
preferred stock were granted registration rights with respect to the
registration under the Securities Act of the shares of common stock issuable
upon conversion of their respective shares of MiningCo's convertible preferred
stock. Comcast will become a party to the amended and restated investors' rights
agreement. As a result, it will receive rights to have its shares of common
stock registered for resale under the Securities Act. Please see "Description of
Securities--Registration Rights."

                           DESCRIPTION OF SECURITIES
 
    The following descriptions of the common stock, the preferred stock and
provisions of MiningCo's certificate of incorporation reflect changes that will
occur upon the filing of an amended and restated certificate of incorporation
prior to the closing of this offering. This document will be filed with the SEC
as an exhibit to MiningCo's registration statement, of which this prospectus
forms a part.
 
    The authorized capital stock of MiningCo consists of 50,000,000 shares of
common stock, par value $.001 per share, and 5,000,000 shares of preferred
stock, par value $.001 per share.
 
COMMON STOCK
 
    As of the date of this prospectus, there are 2,205,406 shares of common
stock outstanding and held of record by 51 stockholders. There will be
11,551,829 shares of common stock outstanding upon the closing of this offering
and the concurrent placement.
 
    Holders of common stock are entitled to one vote for each share on all
matters submitted to a vote of stockholders. Holders of a majority of the shares
of common stock entitled to vote in any election of directors may elect all of
the directors standing for election. Holders of common stock are entitled to
receive dividends, if, as, and when declared by the board of directors out of
funds legally available for such purposes, subject to any dividend preferences
of any outstanding preferred stock. Upon the liquidation, dissolution or winding
up of MiningCo, the holders of common stock are entitled to share ratably in the
assets of MiningCo available for distribution, subject to the preferential
rights of any outstanding preferred stock. Holders of the common stock have no
preemptive, subscription, redemption or conversion rights. Upon the closing of
this offering, there will be no shares of preferred stock outstanding. The
rights, preferences and privileges of holders of common stock are subject to,
and may be adversely affected by, the rights of the holders of shares of any
series of preferred stock that MiningCo may designate and issue in the future.
 
PREFERRED STOCK
 
    As of the date of this prospectus, there are 17,246,122 shares of
convertible preferred stock outstanding. All outstanding shares of convertible
preferred stock will be converted into a total of 6,139,640 shares of common
stock upon the closing of this offering. After the closing, these shares of
convertible preferred stock will no longer be authorized, issued or outstanding.
 
    Upon the closing of this offering, the board of directors will be
authorized, without further stockholder approval, to issue from time to time up
to an aggregate of 5,000,000 shares of preferred stock in one or more series.
The board of directors may fix or alter the designations, preferences, rights
and any qualifications, limitations or restrictions of the shares of each of
these series, including the dividend rights, dividend rates, conversion rights,
voting rights, terms of redemption, redemption price or prices, liquidation
preferences and the number of shares constituting any series or designations of
these series. MiningCo has no present plans to issue any shares of preferred
stock. Please see "--Anti-Takeover Effects of Certain Provisions of Delaware Law
and MiningCo's Certificate of Incorporation and Bylaws."
 
OPTIONS
 
    Options to purchase a total of 3,221,560 shares of common stock may be
granted under the stock option plan. As of the date of this prospectus, there
are outstanding under the stock option plan options to purchase a total of
2,075,267 shares of common stock, of which options to purchase 508,222 shares
are currently exercisable. Of the options to purchase 1,567,045 shares of common
stock that are not currently exercisable, the options to purchase 372,936 shares
of common stock originally granted under MiningCo's predecessor stock option
plan will immediately vest and become exercisable upon the closing of this
offering. In addition, as of the date of this prospectus, there are outstanding
options to
 
                                       57
<PAGE>
purchase a total of 49,787 shares of common stock which were not granted under
the stock option plan, none of which are currently exercisable. Since MiningCo
intends to file a registration statement on Form S-8 as soon as practicable
following the closing of this offering, any shares issued upon exercise of these
options will be immediately available for sale in the public market, subject to
the terms of lock-up agreements entered into between substantially all of these
optionholders and the underwriters. Please see "Management--Amended and Restated
1998 Stock Option/Stock Issuance Plan" and "Shares Eligible for Future Sale."
 
COMMON STOCK WARRANTS
 
    As of the date of this prospectus, MiningCo has outstanding warrants to
purchase a total of 65,860 shares of common stock, at an average exercise price
of $9.80 per share. Of these warrants, the holders of warrants to purchase a
total of 30,260 shares of common stock have entered into lock-up agreements with
the underwriters. The warrants contain anti-dilution provisions providing for
adjustments of the exercise price and the number of shares of common stock
underlying the warrants upon the occurrence of any recapitalization,
reclassification, stock dividend, stock split, stock combination or similar
transaction. The warrants grant to their holders registration rights, described
below, with respect to the common stock issuable upon their exercise. Please see
"Shares Eligible for Future Sale."
 
REGISTRATION RIGHTS
 
    Pursuant to the terms of the amended and restated investors' rights
agreement, after the closing of this offering and the concurrent placement the
holders of 6,779,276 shares of common stock will be entitled to demand that
MiningCo register their shares for resale under the Securities Act. The holders
of 50% or more of the shares of common stock to be issued upon the conversion of
each series of convertible preferred stock are entitled to demand that MiningCo
register their shares under the Securities Act, subject to certain limitations.
MiningCo is not required to effect more than one demand registration for each
group of holders. In addition, after the closing of this offering and the
concurrent placement, these holders and Comcast will be entitled to piggyback
registration rights with respect to the registration of shares of common stock
under the Securities Act. In the event that MiningCo proposes to register any
shares of common stock under the Securities Act, either for its account or for
the account of other security holders, the holders of shares having piggyback
rights are entitled to receive notice of that registration and are entitled to
include their shares in the registration, subject to limitations. Further, at
any time after MiningCo becomes eligible to file a registration statement on
Form S-3, the holders of 6,986,059 shares of common stock may require MiningCo
to file on two occasions Form S-3 registration statements under the Securities
Act with respect to their shares of common stock. These registration rights are
subject to conditions and limitations, among them the right of the underwriters
of an offering to limit the number of shares of common stock to be included in
the registration. MiningCo is generally required to bear all of the expenses of
these registrations, except underwriting discounts and selling commissions.
Registration of any of the shares of common stock held by security holders with
registration rights would result in those shares becoming freely tradable
without restriction under the Securities Act.
 
ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF DELAWARE LAW AND MININGCO'S
  CERTIFICATE OF INCORPORATION AND BYLAWS
 
    MiningCo is subject to the provisions of Section 203 of the Delaware General
Corporation Law (as amended from time to time, the "DGCL"). Section 203 of the
DGCL generally prohibits a publicly-held Delaware corporation from engaging in a
"business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an interested
stockholder, unless the interested stockholder attained that status with the
approval of the board of directors or unless the business combination is
approved in a prescribed manner. A "business combination" includes mergers,
asset sales and other transactions resulting in a financial benefit to the
 
                                       58
<PAGE>
interested stockholder. Subject to exceptions, an "interested stockholder" is a
person who, together with affiliates and associates, owns, or within three years
did own, fifteen percent (15%) or more of a corporation's voting stock. This
statute could prohibit or delay the accomplishment of mergers or other takeover
or change in control attempts with respect to MiningCo and, accordingly, may
discourage attempts to acquire MiningCo.
 
    In addition, certain provisions of the certificate and MiningCo's bylaws,
which will be in effect upon the closing of this offering and which are
described in the following paragraphs, may be deemed to have an anti-takeover
effect and may delay, defer or prevent a tender offer or takeover attempt that a
stockholder might consider in its best interest, including those attempts that
might result in a premium over the market price for the shares held by
stockholders.
 
    BOARD OF DIRECTORS VACANCIES.  The certificate authorizes the board of
directors to fill vacant directorships or increase the size of the board of
directors. This may deter a stockholder from removing incumbent directors and
simultaneously gaining control of the board of directors by filling the
vacancies created by that removal with its own nominees.
 
    STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS.  The certificate
provides that stockholders may not take action by written consent, but only at
duly called annual or special meetings of stockholders. The certificate further
provides that special meetings of stockholders of MiningCo may be called only by
the chairman of the board of directors or a majority of the board of directors.
 
    ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTOR
NOMINATIONS.  The bylaws provide that stockholders seeking to bring business
before an annual meeting of stockholders, or to nominate candidates for election
as directors at an annual meeting of stockholders, must deliver a written notice
to the principal executive offices of MiningCo within a prescribed time period.
The bylaws also specify requirements as to the form and content of a
stockholder's notice. These provisions may preclude stockholders from bringing
matters before an annual meeting of stockholders or from making nominations for
directors at an annual meeting of stockholders.
 
    AUTHORIZED BUT UNISSUED SHARES.  The authorized but unissued shares of
common stock and preferred stock are available for future issuance without
stockholder approval, subject to limitations imposed by the Nasdaq National
Market. These additional shares may be utilized for a variety of corporate
purposes, including future public offerings to raise additional capital,
acquisitions and employee benefit plans. The existence of authorized but
unissued and unreserved common stock and preferred stock could render more
difficult or discourage an attempt to obtain control of MiningCo by means of a
proxy contest, tender offer, merger or otherwise.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
    The certificate provides that, except to the extent prohibited by the DGCL,
MiningCo's directors shall not be personally liable to MiningCo or its
stockholders for monetary damages for any breach of fiduciary duty as directors
of MiningCo. Under the DGCL, the directors have a fiduciary duty to MiningCo
that is not eliminated by this provision of the certificate and, in appropriate
circumstances, injunctions and other nonmonetary relief will remain available.
This provision also does not affect the directors' responsibilities under any
other laws, including the Federal securities laws or state or Federal
environmental laws.
 
    Section 145 of the DGCL enables a corporation to indemnify its directors and
officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers. However, this provision does
not eliminate or limit the liability of a director:
 
    - for any breach of the director's duty of loyalty to the corporation or its
      stockholders,
 
                                       59
<PAGE>
    - for acts or omissions not in good faith or that involve intentional
      misconduct or a knowing violation of law,
 
    - for payments of dividends or approval of stock repurchases or redemptions
      that are prohibited by the DGCL or
 
    - for any transaction from which the director derived an improper personal
      benefit.
 
    MiningCo's certificate provides that it may fully indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding (whether civil, criminal, administrative
or investigative) by reason of the fact that the person is or was a director or
officer of MiningCo or is or was serving at the request of MiningCo as a
director or officer of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise, against expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by that person in connection with any threatened, pending or
completed action, suit or proceeding.
 
   
    MiningCo intends to enter into indemnification agreements with its directors
and executive officers. MiningCo believes that the provisions of its certificate
and bylaws and these agreements are necessary to attract and retain qualified
directors and executive officers. MiningCo's bylaws also permit it to secure
insurance on behalf of any officer, director, employee or other agent for any
liability arising out of his or her actions, regardless of whether the DGCL
would permit indemnification. MiningCo has obtained liability insurance for its
officers and directors.
    
 
    At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent for which indemnification will be required
or permitted under the certificate. MiningCo is not aware of any threatened
litigation or proceeding that may result in a claim for indemnification.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the common stock will be American Stock
Transfer & Trust Company, New York, New York.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this offering, there has not been any public market for the common
stock, and no prediction can be made as to the effect, if any, that market sales
of shares of common stock or the availability of shares of common stock for sale
will have on the market price of the common stock prevailing from time to time.
Nevertheless, sales of substantial amounts of common stock in the public market,
or the perception that such sales could occur, could adversely affect the market
price of the common stock and could impair MiningCo's future ability to raise
capital through the sale of its equity securities.
 
    Upon the closing of this offering and the concurrent placement, MiningCo
will have an aggregate of 11,551,829 shares of common stock outstanding,
assuming no exercise of the underwriters' over-allotment option and no exercise
of outstanding options or warrants. Of the outstanding shares, the 3,000,000
shares being sold in this offering will be freely tradable, except that any
shares held by "affiliates" of MiningCo may only be sold in compliance with the
limitations described below. The remaining 8,551,829 shares of common stock will
be deemed "restricted securities" that may be sold in the public market only if
registered or if they qualify for an exemption from registration under Rules
144, 144(k) or 701 promulgated under the Securities Act. These rules are
summarized below.
 
    Subject to the lock-up agreements described below and the provisions of
Rules 144, 144(k) and 701, additional shares will be available for sale in the
public market as follows:

    In general, under Rule 144, as currently in effect, a person (or persons
whose shares are required to be aggregated), including an affiliate, who has
beneficially owned shares for at least one year is entitled to sell, within any
three-month period commencing 90 days after the date of this prospectus, a
number of shares that does not exceed the greater of (i) 1% of the then
outstanding shares of common stock (approximately 115,518 shares immediately
after this offering and the concurrent placement) or (ii) the average weekly
trading volume in the common stock during the four calendar weeks preceding the
date on which notice of that sale is filed, subject to restrictions. In
addition, a person who is not deemed to have been an affiliate of MiningCo 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 is entitled to sell those
shares under Rule 144(k) without regard to the requirements described above. To
the extent that shares are acquired from an affiliate of MiningCo, the acquiring
person's holding period for the purpose of effecting a sale under Rule 144
commences on the date of transfer from the affiliate.
 
    As of the date of this prospectus, options to purchase a total of 2,125,054
shares of common stock are outstanding, of which options to purchase 508,222
shares are currently exercisable. Of the options to purchase 1,616,832 shares of
common stock that are not currently exercisable, options to purchase 372,936
shares of common stock shall immediately vest and become exercisable upon the
closing of this offering. Upon the closing of this offering, MiningCo intends to
file a registration statement to register for resale the 3,221,560 shares of
common stock reserved for issuance under the stock option plan and
 
                                       61
<PAGE>
the 125,000 shares of Common Stock authorized for issuance under the purchase
plan. That registration statement will automatically become effective upon
filing. Accordingly, shares issued upon the exercise of stock options granted
under the stock option plan will be eligible for resale in the public market
from time to time, subject to vesting restrictions and, in the case of some of
the options the lock-up agreements referred to below. Upon the closing of this
offering, 65,860 shares of common stock will be issuable upon the exercise of
outstanding warrants.
 
    Upon the closing of this offering, MiningCo intends to grant fully vested,
non-qualified stock options to purchase up to 200,000 shares of common stock to
a substantial majority of its guides. The exercise price per share of these
options is expected to be the initial public offering price of the common stock.
 
    MiningCo's directors and officers and stockholders who hold 8,524,259 shares
in the aggregate, together with the holders of options to purchase 2,069,927
shares of common stock and the holders of warrants to purchase 30,260 shares of
common stock, have agreed that they will not sell, directly or indirectly, any
shares of common stock without the prior written consent of Bear, Stearns & Co.
Inc. for a period of 180 days from the date of this prospectus. Please see
"Underwriting."
 
    MiningCo has agreed not to sell or otherwise dispose of any shares of common
stock during the 180-day period following the date of the prospectus, except
MiningCo may issue, and grant options to purchase, shares of common stock under
the stock option plan and the purchase plan. In addition, MiningCo may issue
shares of common stock in connection with any acquisition of another company if
the terms of that issuance provide that the common stock shall not be resold
prior to the expiration of the 180-day period referenced in the preceding
sentence.
 
    Following this offering, some holders of shares of common stock will have
rights to have their shares of common stock registered for resale under the
Securities Act. Please see "Description of Securities--Registration Rights."

</TABLE>
 
    The Underwriting Agreement provides that the obligations of the underwriters
are subject to approval of certain legal matters by counsel and to various other
conditions. The nature of the underwriters' obligations is that they are
committed to purchase and pay for all of the above shares of common stock if any
are purchased. This offering and the concurrent placement are contingent on each
other.
 
    The underwriters propose to offer the shares of common stock directly to the
public at the "initial public offering price" set forth on the cover page of
this prospectus and at that price less a concession not in excess of $  per
share of common stock to certain other dealers who are members of the National
Association of Securities Dealers, Inc. The underwriters may allow, and those
dealers may reallow, concessions not in excess of $    per share of common stock
to certain other dealers. After this offering, this offering price, concessions
and other selling terms may be changed by the underwriters.
 
    MiningCo has granted a 30-day over-allotment option to the underwriters to
purchase up to an aggregate of 450,000 additional shares of common stock of
MiningCo at the "initial public offering price" less the "underwriting
discounts", each as set forth on the cover page of this prospectus. If the
underwriters exercise this option in whole or in part, then each of the
underwriters will be severally committed, subject to certain conditions,
including the approval of certain matters by counsel, to purchase the additional
shares of common stock in proportion to their respective purchase commitments as
indicated in the preceding table.
 
    The underwriters, at the request of MiningCo, have reserved for sale at the
initial public offering price up to ten percent (10%) of the shares of common
stock to be sold in this offering for sale to employees and directors of
MiningCo and other persons designated by MiningCo. The number of shares
available for sale to the general public will be reduced to the extent that any
reserved shares are purchased. Any reserved shares not so purchased will be
offered by the underwriters on the same basis as the other shares offered
hereby.
 
    Wit Capital is making a prospectus in electronic format available on its
Internet web site. All dealers purchasing shares from Wit Capital in this
offering have also agreed to make a prospectus in electronic format available on
web sites maintained by each of the dealers. Other than the prospectus in
electronic format, the information on such web sites is not part of this
prospectus or the registration statement of which this prospectus forms a part,
has not been approved and/or endorsed by MiningCo or any underwriter in such
capacity and should not be relied on by prospective investors.
 
    The underwriters do not expect to confirm sales of common stock to any
accounts over which they exercise discretionary authority.
 
                                       63
<PAGE>
    The underwriting agreement provides that MiningCo will indemnify the
underwriters against certain liabilities under the Securities Act of 1933, as
amended, or will contribute to payments that the underwriters may be required to
make in respect thereof.
 
   
    MiningCo's directors and officers and stockholders who hold 8,524,259 shares
in the aggregate, together with the holders of options to purchase 2,069,927
shares of common stock and the holders of warrants to purchase 30,260 shares of
common stock, have agreed that they will not sell, directly or indirectly, any
shares of common stock without the prior written consent of Bear, Stearns & Co.
Inc. for a period of 180 days from the date of this prospectus. However, Bear,
Stearns & Co. Inc. may, in its sole discretion and at any time or from time to
time, without notice to MiningCo's stockholders or to Nasdaq, release all or any
portion of the securities subject to lock-up agreements.
    
 
    In addition, MiningCo has agreed that for a period of 180 days after the
date of this prospectus it will not, without the prior written consent of Bear,
Stearns & Co. Inc., offer, sell or otherwise dispose of any shares of common
stock except for the shares of common stock offered by this prospectus and in
the concurrent placement, the shares of common stock issuable upon exercise of
outstanding warrants and the shares issued and options granted pursuant to
MiningCo's stock option plan and purchase plan.
 
    Prior to this offering, there has been no public market for the common stock
of MiningCo. Consequently, the initial offering price for the common stock will
be determined by negotiations between MiningCo and the representatives of the
underwriters. Among the factors to be considered in those negotiations will be:
 
    - the results of operations of MiningCo in recent periods;
 
    - estimates of the prospects of MiningCo and the industry in which MiningCo
      competes;
 
    - an assessment of MiningCo's management;
 
    - the general state of the securities markets at the time of this offering;
      and
 
    - the prices of similar securities of generally comparable companies.
 
MiningCo's common stock has been approved for quotation on the Nasdaq National
Market under the symbol MINE. There can be no assurance, however, that an active
or orderly trading market will develop for the common stock or that the common
stock will trade in the public markets subsequent to this offering at or above
the initial offering price.
 
    In order to facilitate this offering, persons participating in this offering
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common stock during and after this offering, including
over-allotment, stabilizing and short-covering transactions and the impositions
of penalty bids. Persons participating in this offering may also engage in
passive market making transactions in the common stock on the Nasdaq National
Market. Specifically, the underwriters may over-allot or otherwise create a
short position in the common stock for their own account by selling more shares
of common stock than have been sold to them by MiningCo. The underwriters may
elect to cover this short position by purchasing shares of common stock in the
open market or by exercising the over-allotment option granted to the
underwriters. In addition, the underwriters may stabilize or maintain the price
of the common stock by bidding for or purchasing shares of common stock in the
open market and may impose penalty bids, under which selling concessions allowed
to syndicate members or other broker-dealers participating in this offering are
reclaimed if shares of common stock previously distributed in this offering are
repurchased in connection with stabilization transactions or otherwise. The
effect of these transactions may be to stabilize or maintain the market price at
a level above that which might otherwise prevail in the open market. The
imposition of a penalty bid may also affect the price of the common stock to the
extent that it discourages resales. No representation is made as to the
magnitude or effect of this stabilization or other transactions. These
transactions may be effected on the Nasdaq National Market or otherwise and, if
commenced, may be discontinued at any time.

MiningCo.com, Inc.:
 
    When the reverse stock split referred to in Note 14 of the Notes to
Financial Statements has been consummated, we will be in a position to render
the following report.
 
                                          KPMG LLP
 
                                          /S/ KPMG LLP
 
                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
MiningCo.com, Inc.:
 
    We have audited the accompanying balance sheets of MiningCo.com, Inc. as of
December 31, 1997 and 1998, and the related statements of operations,
stockholders' deficit and cash flows for the period from June 27, 1996
(inception) to December 31, 1996 and for the years ended December 31, 1997 and
1998. 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 in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of MiningCo.com, Inc. as of
December 31, 1997 and 1998, and the results of its operations and its cash flows
for the period from June 27, 1996 (inception) to December 31, 1996 and for the
years ended December 31, 1997 and 1998 in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1998 IS UNAUDITED)
 
(1)  ORGANIZATION AND BUSINESS
 
    MiningCo.com, Inc. ("MiningCo") was incorporated in New York on June 27,
1996 (inception) as General Internet Inc. and commenced operations on that date.
In December 1998, MiningCo reincorporated in Delaware. MiningCo's Internet
service, MININGCO.COM, is an Internet news, information and entertainment
service. MiningCo's network is comprised of numerous GuideSites, each of which
focuses on a particular topic and is managed by a human guide. The guides are
independent contractors who are compensated based on the greater of a monthly
guarantee or a percentage of advertising revenues generated by all of the
GuideSites. MiningCo's primary revenue source is the sale of advertising.
 
    MiningCo's business is characterized by rapid technological change, new
product and service development and evolving industry standards. Inherent in the
Company's business are various risks and uncertainties, including its limited
operating history, uncertain profitability, history of losses, anticipated
continuing losses, the dependence on the Internet and risks associated with
Internet advertising.
 
(2)  SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES
 
    (A) INITIAL PUBLIC OFFERING, CONCURRENT PLACEMENT AND UNAUDITED PRO FORMA
     BALANCE SHEET
 
    In December 1998, the Board of Directors authorized the filing of a
registration statement with the Securities and Exchange Commission ("SEC") that
would permit MiningCo to sell shares of MiningCo's common stock in connection
with a proposed initial public offering ("IPO").
 
    On February 23, 1999, MiningCo and Comcast Interactive Investments, Inc.
("Comcast") entered into a common stock purchase agreement pursuant to which
MiningCo has agreed to sell Comcast up to $2,500,000 of common stock. Since
Comcast will purchase the shares directly from MiningCo in a private placement
transaction, the underwriters will not receive any discount or commission
relating to the sale of the shares. As a result, Comcast will purchase the
shares at a price of 93% of the initial public offering price per share. The
closing of the concurrent placement and the IPO are contingent on each other.
 
    If the IPO is consummated under the terms presently anticipated, upon the
closing of the proposed IPO, each of the then outstanding shares of the
Company's convertible preferred stock will automatically convert into 0.356
shares of common stock (see note 10).
 
    The accompanying pro forma balance sheet as of December 31, 1998 gives
effect to (a) the automatic conversion of 3,346,715, 6,597,596 and 7,301,811
shares of Series A, B and C convertible preferred stock, respectively,
representing all outstanding shares of convertible preferred stock, into
6,139,640 shares of common stock (see note 10) and (b) the automatic forgiveness
and cancellation of $337,100 in unsecured promissory notes payable (see note 8),
both upon the closing of the IPO.
 
    (B) USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

three months or less to be cash equivalents, which principally consist of money
market accounts.
 
    (D) PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation is computed using the straight-line method over three
years, which is the estimated useful life of the related assets. Leasehold
improvements are amortized over their estimated useful lives, or the term of the
related lease, whichever is shorter. Equipment under capital leases is stated at
the present value of minimum lease payments and is amortized using the
straight-line method over the shorter of the lease term or the estimated useful
life of the assets.
 
    (E) DEBT ISSUANCE COSTS
 
    Amortization of debt issuance costs is calculated on the straight-line
method over the life of the related debt instrument.
 
    (F) IMPAIRMENT OF LONG-LIVED ASSETS
 
    MiningCo reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of the assets to future net cash flows
expected to be generated by the assets. If the assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the fair value of the assets. To date, no
impairment has occurred.
 
    (G) INCOME TAXES
 
    MiningCo accounts for income taxes using the asset and liability method.
Under this method, deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases and operating loss and tax credit carryforwards. Deferred
tax assets and liabilities are measured using enacted tax rates expected to
apply to taxable income in the years in which those temporary differences are
expected to be recovered or settled. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in results of operations in
the period that includes the enactment date.
 
    (H) REVENUE AND EXPENSE RECOGNITION
 
    REVENUE RECOGNITION
 
    To date, substantially all of MiningCo's revenues have been derived from the
sale of advertisements on MININGCO.COM. MiningCo offers numerous sizes and types
of advertising placement, including banner advertisements, button
advertisements, text links and sponsorship programs. Revenues from advertising
sales are recognized ratably in the period in which the advertisement is
displayed,

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1998 IS UNAUDITED)
 
(2)  SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
provided that no significant MiningCo obligations remain and collection of the
resulting receivable is probable. Payments received from advertisers prior to
displaying their advertisements on MININGCO.COM are recorded as deferred revenue
and are recognized as revenue ratably as the advertisements are displayed.
Pursuant to its agreements with advertisers, MiningCo generally guarantees a
minimum number of impressions (times that an advertisement appears in pages
viewed by the users of MININGCO.COM) for a fixed fee. To the extent minimum
guaranteed impression levels are not met, MiningCo defers recognition of the
corresponding revenues until guaranteed impression levels are achieved.
MiningCo's short-term advertising agreements are generally terminable by either
party upon relatively short notice. MiningCo's agreements with its electronic
commerce partners are typically longer in length, and in certain cases, entitle
MiningCo to a share of revenues generated by sales over a particular threshold
resulting from direct links from MININGCO.COM. To date, MiningCo has not
recognized any revenues from these revenue sharing agreements. MiningCo's
revenue derived from these revenue sharing agreements will be recognized by
MiningCo upon notification from its advertisers and electronic commerce partners
of sales attributable to MININGCO.COM.
 
    A portion of MiningCo's revenues are from barter advertisements (agreements
whereby MiningCo trades advertisements on MININGCO.COM in exchange for
advertisements on third-party web sites). Barter advertising revenues and
expenses are recorded at the fair market value of services provided or received,
whichever is more determinable in the circumstances. Revenue from barter
advertising transactions is recognized as income when advertisements are
delivered on MININGCO.COM. Barter expense is recognized when MiningCo's
advertisements are run on third-party web sites, which is typically in the same
period when barter revenue is recognized. Barter expense is included as a
component of cost of revenues. Barter advertising revenues and expenses were $0,
$72,500 and $365,700 for the period from June 27, 1996 (inception) through
December 31, 1996 and for the years ended December 31, 1997 and 1998,
respectively.
 
    At December 31, 1998, accounts receivable include approximately $417,300 of
unbilled receivables, $392,300 of which have been subsequently billed. Such
unbilled receivables represent the recognized sales value of short term
advertising contracts that were earned but not billable to customers at December
31, 1998. The terms of the related advertising contracts typically require
billing at the end of 30, 60 or 90 days from the signing of the contract.
 
   
    EXPENSE RECOGNITION--GUIDE COMPENSATION
    
 
    MiningCo's guides are compensated at an amount equal to the greater of a
monthly minimum guarantee or a percentage of net advertising revenues generated
by the entire GuideSite network, which is distributed among the guides based on
the user traffic on their respective GuideSites. Net advertising revenues has
been defined as total advertising revenues received less particular types of
non-cash revenues, third-party advertising sales representative organization
fees and marketing expenses. Guides are currently entitled to a percentage of
net transaction revenues and net syndication revenues. In addition, management
may distribute a semi-annual discretionary bonus to guides. Guide compensation
is included as a component of cost of revenues.

(2)  SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
   
    EXPENSE RECOGNITION--DISTRIBUTION AND SYNDICATION PARTNERSHIPS
    
 
   
    MiningCo has entered into distribution and syndication partnership
agreements that drive traffic to MININGCO.COM. Through these partnerships,
MiningCo provides content to a partner's web site, and users can link to
MININGCO.COM by clicking on the content. MiningCo has agreements to provide
content to some of the leading Internet service providers, content web sites,
search engines/Internet directories and broadband cable-related sites. These
short term agreements typically require MiningCo to make payments, which are
expensed, that are either fixed or are based on the amount of user traffic
directed from the partner's site to MININGCO.COM.
    
 
    (I) PRODUCT DEVELOPMENT EXPENSES
 
    Product development expenses include personnel and consulting costs
associated with the design, development and testing of MININGCO.COM and
MiningCo's systems and editorial personnel costs. MiningCo generally expenses
its product development expenses as incurred. Software development costs are
required to be capitalized when a product's technological feasibility has been
established by completion of a working model of the product. To date, completion
of a working model of MiningCo's service and general release have substantially
coincided. As a result, MiningCo has not capitalized any software development
costs since those costs have not been significant.
 
    (J) ADVERTISING EXPENSES
 
    MiningCo expenses the costs of advertising its service as incurred. These
costs amounted to $60,000, $510,900 and $5,262,800 for the period from June 27,
1996 (inception) through December 31, 1996 and for the years ended December 31,
1997 and 1998, respectively, and are included in sales and marketing in
MiningCo's statements of operations.
 
    (K) STOCK-BASED COMPENSATION
 
    MiningCo accounts for its employee stock option plans in accordance with the
provisions of Accounting Principles Board ("APB") Opinion No. 25, "Accounting
for Stock Issued to Employees," and related interpretations. Compensation
expense related to employee stock options is recorded only if, on the date of
grant, the fair value of the underlying stock exceeds the exercise price.
MiningCo adopted the disclosure-only requirements of Statement of Financial
Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation," which allows entities to continue to apply the provisions of APB
Opinion No. 25 for transactions with employees and provide pro forma net income
and pro forma earnings per share disclosures for employee stock as if the
fair-value-based method of accounting in SFAS No. 123 had been applied to these
transactions.
 
    MiningCo accounts for non-employee stock-based awards in which goods or
services are the consideration received for the equity instruments issued based
on the fair value of the consideration received or the fair value of the equity
instrument issued, whichever is more reliably measured.

(2)  SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    (L) BASIC AND DILUTED NET LOSS PER COMMON SHARE
 
    MiningCo adopted SFAS No. 128, "Computation of Earnings Per Share," during
the year ended December 31, 1997. In accordance with SFAS No. 128 and the SEC
Staff Accounting Bulletin No. 98, basic earnings per share is computed using the
weighted average number of common and dilutive common equivalent shares
outstanding during the period. Common equivalent shares consist of the
incremental common shares issuable upon the conversion of the convertible
preferred stock (using the if-converted method) and shares issuable upon the
exercise of stock options and warrants (using the Treasury Stock method); common
equivalent shares are excluded from the calculation if their effect is
anti-dilutive. Pursuant to SEC Staff Accounting Bulletin No. 98, all options,
warrants or other potentially dilutive instruments issued for nominal
consideration, prior to the anticipated effective date of an initial public
offering (including the IPO), are required to be included in the calculation of
basic and diluted net loss per share, as if they were outstanding for all
periods presented. As a result, MiningCo has included 218,890 shares of common
stock in the calculation of basic and diluted net loss per common share for all
periods presented which relate to certain investor warrants issued for nominal
consideration, all of which were exercised in December 1998 when MiningCo
exercised its right to call those warrants (see notes 8 and 10).
 
    Diluted net loss per common share for the period from June 27, 1996
(inception) through December 31, 1996, the years ended December 31, 1997, and
1998, does not include the effects of options to purchase 0, 818,638, and
1,178,436 shares of common stock, respectively, 0, 427,003, and 68,708 common
stock warrants, respectively, or 0, 0 and 6,139,640 shares of convertible
preferred stock on an "as if" converted basis, respectively, as the effect of
their inclusion is anti-dilutive during each period.
 
   
    The pro forma net loss per common share for the year ended December 31, 1998
is computed by dividing the net loss by the sum of the weighted average number
of shares of common stock outstanding and the shares resulting from the
automatic conversion of all of the outstanding convertible preferred stock into
6,139,640 shares of common stock, as if they had been outstanding for the entire
year ended December 31, 1998.
    
 
    (M) STOCK SPLIT
 
    In August 1996, MiningCo authorized and implemented a 1-for-40,000 common
stock split. Accordingly, all share and per share information in the
accompanying financial statements has been retroactively restated to reflect the
effect of the stock split (see note 14).
 
    (N) DEFERRED OFFERING COSTS
 
    At December 31, 1998, specific incremental costs directly attributable to
the IPO transaction have been deferred for an aggregate amount of $568,700.
 
    (O) RECENT ACCOUNTING PRONOUNCEMENTS
 
    As of January 1, 1998, MiningCo adopted the provisions of SFAS No. 130,
"Reporting Comprehensive Income", which establishes standards for reporting and
displaying comprehensive
 
                                      F-12

(2)  SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
income and its components in a full set of general purpose financial statements.
The adoption of this standard has had no impact on MiningCo's financial
statements. Accordingly, MiningCo's comprehensive net loss is equal to its net
loss for all periods presented.
 
    In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information", which establishes standards for the way
that a public enterprise reports information about operating segments in annual
financial statements, and requires that those enterprises report selected
information about operating segments in interim financial reports issued to
shareholders. It also establishes standards for related disclosures about
products and services, geographic areas and major customers. SFAS No. 131 is
effective for fiscal years beginning after December 15, 1997. In the initial
year of application, comparative information for earlier years must be restated.
MiningCo has determined that it does not have any separately reportable business
segments.
 
    In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use" ("SOP 98-1"), which provides guidance
for determining whether computer software is internal-use software and on
accounting for the proceeds of computer software originally developed or
obtained for internal use and then subsequently sold to the public. It also
provides guidance on capitalization of the costs incurred for computer software
developed or obtained for internal use. MiningCo does not expect the adoption of
SOP 98-1 to have a material effect on its capitalization policy.
 
    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities", which establishes accounting and reporting
standards for derivative instruments, including derivative instruments embedded
in other contracts, and for hedging activities. SFAS No. 133 is effective for
all fiscal quarters of fiscal years beginning after June 15, 1999. This
statement is not expected to affect MiningCo as MiningCo currently does not
engage or plan to engage in derivative instruments or hedging activities.
 
(3)  BUSINESS AND CREDIT CONCENTRATIONS
 
    Financial instruments which subject MiningCo to concentrations of credit
risk consist primarily of cash and cash equivalents, accounts receivable,
accounts payable and accrued liabilities. The carrying amounts of these
instruments approximate fair value. The carrying amount of MiningCo's capital
leases and other equipment financing obligations approximates the fair value of
these instruments based upon management's best estimate of interest rates which
are similar to the rates obtained in its January and February 1999 lease line of
credit (see note 13).
 
    MiningCo maintains cash and cash equivalents with a domestic financial
institution. MiningCo performs periodic evaluations of the relative credit
standing of this institution. From time to time, MiningCo's cash balances with
this financial institution may exceed Federal Deposit Insurance Corporation
insurance limits.
 
    MiningCo's customers are concentrated in the United States. MiningCo
performs ongoing credit evaluations, generally does not require collateral and
establishes an allowance for doubtful accounts based upon factors surrounding
the credit risk of each customer, historical trends and other information; to
date, such amounts have been within management's expectations.

(3)  BUSINESS AND CREDIT CONCENTRATIONS (CONTINUED)
    For the period from June 27, 1996 (inception) to December 31, 1996, there
were no customers that accounted for over 10% of total revenues generated by
MiningCo, or of gross accounts receivable at December 31, 1996.
 
    For the year ended December 31, 1997, one customer accounted for
approximately 19% of total revenues generated by MiningCo. No customers
accounted for over 10% of gross accounts receivable at December 31, 1997. As of
December 31, 1997, MiningCo had receivables in excess of $10,000 from three
separate customers totaling approximately $43,000.
 
    For the year ended December 31, 1998, one customer accounted for
approximately 12% of total revenues generated by MiningCo. This advertising
arrangement ended on December 31, 1998. For the year ended December 31, 1998, a
third-party Internet advertising sales representative organization accounted for
approximately 21% of MiningCo's total revenues and accounted for approximately
35% of gross accounts receivable at December 31, 1998, totaling approximately
$376,000.
 
    In June 1997, MiningCo entered into a consulting agreement with a major
financial institution pursuant to which MiningCo agreed to provide consulting
assistance in connection with the development of micro communities for an
aggregate amount of $450,000. Fees in connection with this agreement have been
recognized as performance occurred under the terms of the agreement, net of any
expenses, and have been recorded as other income for the year ended December 31,
1997. In connection with this agreement, MiningCo issued the financial
institution a warrant to purchase 35,600 shares of common stock at $14.05 per
share with an expiration date of December 31, 1999. The fair value of the
warrants, using the Black-Scholes model based upon the following assumptions:
risk-free interest rate of 6%; dividend yield of 0%; expected life of 2.5 years;
and volatility of 0%, was deemed insignificant on the date of grant.

(5)  INCOME TAXES
 
    No provision for US federal or state income taxes has been recorded for any
period as MiningCo has incurred operating losses since inception.
 
    Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
MiningCo's deferred tax assets for federal and state income taxes are as
follows:

</TABLE>
 
    Realization of deferred tax assets is dependent upon future earnings, if
any. MiningCo has recorded a full valuation allowance against its deferred tax
assets since management believes that it is not more likely than not that these
assets will be realized. No income tax benefit has been recorded for all periods
presented because of the valuation allowance.
 
    During the period from June 27, 1996 (inception) to December 31, 1996, the
years ended December 31, 1997 and 1998, the valuation allowance for the deferred
tax assets increased by $1,121,000, $3,967,000, and $7,159,000, respectively.
 
    As of December 31, 1997 and 1998, MiningCo had net operating loss
carryforwards for federal income tax purposes of approximately $10.6 million and
$26.3 million, respectively. There can be no assurance that MiningCo will
realize the benefit of the net operating loss carryforwards. The federal net
operating loss carryforwards are available to offset future taxable income and
expire at various dates beginning in fiscal year 2011 through 2013 if not
utilized.
 
    Due to the "change in ownership" provisions of the Internal Revenue Code,
the availability of MiningCo's net operating loss and credit carryforwards may
be subject to an annual limitation against taxable income in future periods,

into a convertible note payable (see note 8). During 1998, Mr. Kurnit elected to
defer an additional $67,000 of compensation, which at December 31, 1998 totaled
$181,700.
 
   
    On April 20, 1998, MiningCo and a director of an investor in MiningCo
executed an advisory agreement, pursuant to which, the individual agreed to
provide consulting and advisory services to MiningCo including, but not limited
to, introducing MiningCo to members of the investment community and assisting
MiningCo with respect to financial and strategic matters. In consideration for
his services under the advisory agreement, the individual was issued a warrant
to purchase up to an aggregate of 21,360 shares of MiningCo's common stock, at
an exercise price of $5.06 per share. The warrant is exercisable at any time
during the 10-year period commencing on the date of the closing of a qualified
initial public offering (which would include the IPO). The fair value of the
warrants, using the Black-Scholes model and the following assumptions: (1)
risk-free interest rate of 6%, dividend yield of 0%, expected life of ten years,
and volatility of 0%, resulted in a compensation charge of $36,000 during 1998.

    On October 17, 1996, MiningCo executed a secured 8.25% Promissory Note
("8.25% Note") in the original principal amount of $3,905,600. On August 27,
1997, the 8.25% Note was amended to, among other things, reduce the principal
amount outstanding thereunder to $3,255,600, reflecting a reduction of $650,000
which was converted into a convertible note payable. In connection with the
execution of the convertible note payable (see note 8), MiningCo issued warrants
to purchase 24,105 shares of MiningCo's common stock at an exercise price of
$4.21 per share. The fair value of the warrants, using a Black-Scholes model and
the following assumptions: risk-free interest rate of 5.7%, dividend yield of
0%, expected life of ten years and volatility of 0%, was deemed insignificant on
the date of grant.

    On April 23, 1998, the 8.25% Note was amended again to, among other things,
(i) reduce the principal amount outstanding thereunder to $1,555,600, reflecting
a reduction of $1,700,000 which was simultaneously converted into 944,444 shares
of Series B convertible preferred stock ("Series B Preferred") (see notes 9 and
10), (ii) reduce the interest amount outstanding thereunder by $305,800, which
was simultaneously converted into 169,883 shares of Series B Preferred, and
(iii) provide that the remaining principal and interest would automatically
convert into shares of MiningCo's Series C convertible preferred stock ("Series
C Preferred") upon the closing of the next financing conducted by MiningCo if
the next sale of equity to new investors on or prior to March 31, 1999 was at a
price per share less than $3.00 per share (on a pre-split basis), otherwise the
note was due and payable on March 31, 1999. On November 13, 1998, MiningCo
issued 913,856 shares of MiningCo's Series C Preferred at $1.95 per preferred
share in consideration for the cancellation of the remaining $1,555,600 of
principal and $226,400 of interest outstanding under the 8.25% Note.
 
    In January, June and July 1998, MiningCo issued to the holder of the 8.25%
Note warrants to purchase an additional 2,670, 2,111 and 4,119 shares of
MiningCo's common stock at an exercise price of $4.21 per share in consideration
for entering into a subordination agreement with another creditor of MiningCo.
The value attributed to the warrants, using a Black-Scholes pricing model and
the following assumptions: risk-free interest rate of 6.0%, dividend yield of
0%, expected life of ten years and volatility of 0%, was $18,000 in the
aggregate, based upon the respective grant dates, which was recorded as
additional interest expense in 1998.
 
    NOTES PAYABLE--CREDIT FACILITY
 
    During January 1998, MiningCo entered into an asset backed credit facility
with Phoenix Leasing Incorporated ("Phoenix") which was funded as MiningCo
pledged fixed assets as security to Phoenix. During the year ended December 31,
1998, MiningCo received a total loan of $507,700 and pledged $507,700 of fixed
assets as security. The effective interest rate of the credit facility is 18%.
As of December 31, 1998, the balance outstanding was $437,500 of which $154,000
is due in 1999, $157,000 in 2000 and $126,500 in 2001.

    Between March 27, 1997 and January 15, 1998, MiningCo issued several secured
subordinated notes, which converted into Series A Notes ("Series A Notes"), for
an aggregate principal amount of $4,950,000, which amount included (i) the
conversion of $650,000 from the 8.25% Notes and (ii) the conversion of $300,000
of deferred compensation owed to Mr. Kurnit. These notes bore interest at a
variable rate equal to the prime rate plus two percent per annum. At December
31, 1997, prime rate plus 2% was 10.5%. Pursuant to their terms, the principal
due on the Series A Notes were automatically convertible into shares of
MiningCo's common stock or convertible preferred stock upon the closing of the
next equity financing conducted by MiningCo. The conversion price for these
notes, as provided for in the original note agreement, was $1.50 per preferred
share.
 
    In connection with the issuance of this debt, MiningCo issued warrants to
purchase 218,890 shares of MiningCo's common stock at an exercise price of $0.03
per share and 90,858 shares of MiningCo's common shares at an exercise price of
$4.21 per share (which includes warrants to purchase 24,105 shares relating to
the conversion of $650,000 from the 8.25% Notes), all of which expire ten years
from their date of issuance; provided that, under certain circumstances,
MiningCo could cancel the warrants after providing the holders thereof a
reasonable period of time to exercise the warrants prior to their cancellation.
The value attributed to the warrants was $106,000 for warrants issued with an
exercise price of $0.03 and $31,000 for warrants issued with an exercise price
of $4.21 per share. These values were estimated, using a Black-Scholes pricing
model, based on the following assumptions: risk-free interest rate of 6.0%,
dividend yield of 0%, expected life of 10 years and volatility of 0%. These

amounts were recorded as an original issue debt discount and amortized to
interest expense over the life of the loans. In December 1998, MiningCo
exercised its right to call certain investor warrants which resulted in the
issuance of 218,890 shares of common stock at $0.03 per share and 66,753 shares
of common stock at $4.21 per share for net cash proceeds of approximately
$287,600. The remaining 24,105 warrants with an exercise price of $4.21 per
share were cancelled.
 
    On April 23, 1998, MiningCo issued an aggregate of 3,346,715 shares of
Series A Preferred, at a purchase price of $1.50 per preferred share, to holders
of the Series A Notes, in consideration for the cancellation of all principal
owed under the Series A Notes and $70,000 of interest accrued under the Series A
Notes prior to August 12, 1997. All remaining interest under the Series A Notes
up through April 23, 1998 was evidenced by newly issued unsecured promissory
notes of MiningCo which amounted to $337,100 as of December 31, 1998. The notes
bear interest at 6% and have no due date. In accordance with the terms of the
note upon the closing of a qualified initial public offering (including the
IPO), all amounts due under these unsecured promissory notes will automatically,
by its original terms, be forgiven and canceled. Accordingly, such amount shall
be recorded as a contribution to additional paid in capital upon the closing of
the IPO.

    Between November 1997 and February 1998, MiningCo issued several secured
subordinated notes ("Series B Notes") for an aggregate principal amount of
$2,800,000, of which $1,000,000 bore interest at a variable rate equal to the
prime rate plus two percent per annum and $1,800,000 bore interest at 10%
percent per annum and were due on demand. At December 31, 1997, prime rate plus
2% was 10.5%. Pursuant to their terms, the Series B Notes were automatically
convertible into shares of MiningCo's Series B Preferred upon the closing of the
next equity financing conducted by MiningCo. The conversion price for these
notes, as provided for in the original note agreement, was $1.80 per preferred
share.
 
    In connection with the issuance of this debt, MiningCo issued warrants to
purchase 250,192 shares of MiningCo's common stock at an exercise price of $5.06
per share, all of which expire ten years from their date of issuance; provided
that, under certain circumstances, MiningCo may cancel the warrants after
providing the holders thereof a reasonable period of time to exercise the
warrants prior to their cancellation. The fair value of the warrants, using the
Black-Scholes model and the following assumptions: risk-free interest rate of
6.0%, dividend yield of 0%, expected life of 10 years and volatility of 0%, was
$150,000 and recorded as additional interest expense. In December 1998, MiningCo
exercised its right to call certain investor warrants which resulted in the
issuance of 250,192 shares of common stock at $5.06 per share for net cash
proceeds of approximately $1,266,000.
 
    On April 23, 1998, MiningCo issued 1,594,380 shares of Series B Preferred,
at a purchase price of $1.80 per share, to holders of the Series B Notes, in

    On April 23, 1998, MiningCo issued an aggregate of 6,597,596 shares of
Series B Preferred, at a purchase price of $1.80 per share, to (i) holders of
the Series B Notes in consideration for the cancellation of all indebtedness of
MiningCo under the Series B Notes, amounting to $2,869,900, (ii) the 8.25% Note
holder, in consideration for the cancellation of $1,700,000 in principal and
$305,800 in accrued interest, and (iii) $7,000,000 from other investors.
 
    In connection with the issuance of the Series B Preferred, MiningCo issued
warrants to purchase 107,695 shares of MiningCo's common stock at an exercise
price of $7.02 per share, all of which expire ten years from their date of
issuance; provided that, under certain circumstances, MiningCo may cancel the
warrants after providing the holders with a reasonable period of time to
exercise the warrants prior to their cancellation. In December 1998, MiningCo
exercised its right to call certain investor warrants which resulted in the
issuance of 103,801 shares of common stock at $7.02 per share for net cash
proceeds of approximately $702,800. The warrant for the remaining 3,894 shares
was cancelled.
 
    On October 5, 1998, MiningCo delivered a number of convertible promissory
notes ("Series C Notes") in the aggregate principal amount of $1,081,000.
Pursuant to their terms, the Series C Notes were automatically convertible into
shares of MiningCo's Series C Convertible Preferred Stock ("Series C
Preferred"), at a conversion price equal to the lesser of $3.60 per share of
Series C Preferred or the purchase price per share of the Series C Preferred,
upon the closing of the next equity financing conducted by MiningCo. The
conversion price for the notes was $1.95 per preferred share which was the
highest price paid for the Company's preferred stock during such time period.
 
    On November 13, 1998 and December 4, 1998, MiningCo issued an aggregate of
7,301,811 shares of Series C Preferred, at a purchase price of $1.95 per share,
to (i) holders of the Series C Notes in consideration for the cancellation of
all indebtedness of MiningCo under the Series C Notes, amounting to $1,089,900
(ii) the holders of the Series C Notes in consideration for the payment of
$2,322,000, (iii) the 8.25% Note holder, in consideration for the cancellation
of $1,782,000 in principal and accrued interest, and (iv) other investors in
consideration for the payment of $9,044,600, including $762,600 from existing
stockholders pursuant to participation rights granted to those stockholders.
 
    The following summarizes the Convertible Notes Payable--Series C Notes
activity during 1998:

payment of any cash dividend on common stock, when and as declared by the Board
of Directors of MiningCo. Upon the closing of a qualified initial public

number of whole shares of common stock into which the shares of preferred stock
are convertible into on the date of the vote.
 
    Each share of Series A Preferred, Series B Preferred and Series C Preferred
is convertible into 0.356 shares of common stock, as adjusted for dilutive
issuances of stock and other securities. In the event of any liquidation or
dissolution of MiningCo, including certain mergers, consolidations and asset
sales, holders of the Series A Preferred, Series B Preferred and Series C
Preferred will receive a liquidation preference if the total proceeds of the
sale or liquidation are less than $60,000,000. Series A Preferred, Series B
Preferred and Series C Preferred stockholders first receive the purchase price
of their Series A Preferred, Series B Preferred and Series C Preferred shares,
as applicable, plus all accrued and/or declared but unpaid dividends, before
sharing the balance of the proceeds on an as-converted basis with common
stockholders. At the option of the stockholders, Series A Preferred, Series B
Preferred and Series C Preferred may be converted into shares of common stock;
however, those shares automatically convert into common shares in the event of a
qualified initial public offering (including the IPO) resulting in proceeds to
MiningCo of not less than $15 million and at an offering price per share equal
to at least $10.00 per common share. If the IPO is consummated under the terms
currently anticipated, upon the closing of the proposed IPO, 3,346,715,
6,597,596 and 7,301,811 shares of Series A, B and C convertible preferred stock,
respectively, representing all of the outstanding shares of convertible
preferred stock, shall automatically convert into 6,139,640 shares of common
stock.

    COMMON STOCK
 
    During 1996, MiningCo issued shares of common stock to its founders and
original employees at approximately $0.03 per share. MiningCo's right to
repurchase these shares in certain circumstances was to lapse over a period of
three years. During 1997, MiningCo's Board of Directors approved a resolution to
cancel these shares in exchange for incentive stock options. Accordingly, on
March 20, 1997, MiningCo canceled 367,802 common shares and exchanged these
shares on a one-for-one basis for participation in the 1997 Employee Stock
Incentive Plan. These incentive stock options were granted with an exercise
price equal to their fair market value, or $0.51 per share, at the date of grant
as determined by an independent valuation.

(10)  CAPITALIZATION (CONTINUED)
    At December 31, 1998, there were 68,708 shares of common stock reserved for
issuance upon exercise of outstanding warrants at a weighted average exercise
price of $9.66 per share, of which 2,848 warrants in the aggregate with an
exercise price of $6.32 per share were exercised on January 11, 1999.
 
   
    The weighted-average fair value of warrants granted during 1997 and 1998 was
$0.25 and $1.03, respectively, on the date of grant using a Black Scholes
pricing model with the following weighted-average assumptions for 1997 and 1998:
(i) risk-free interest rate-6.0% for both years; (ii) dividend yield-0.0% for
both years; (iii) expected life-10 years for both years.
    
 
    As of December 31, 1998, the following number of warrants to purchase common
stock remain outstanding: 8,900 shares at $4.21 per share; 21,360 shares at
$5.06 per share; 2,848 shares at $6.32 per share (which where exercised on
January 11, 1999); and 35,600 shares at $14.05 per share.
 
(11)  STOCK OPTION PLAN
 
    MiningCo's Board of Directors has authorized 996,800 shares at December 31,
1997 and 1,886,800 shares at December 31, 1998 of its common stock for issuance
pursuant to its 1998 Stock Option/Stock Issuance Plan (successor plan to
MiningCo's 1997 Employee Incentive Stock Option Plan). On February 1, 1999, the
Board of Directors and shareholders increased the authorized number of shares
authorized under the plan by 890,000 shares, effectively authorizing 2,776,800
in the aggregate. These options have ten year terms and have been issued at the
fair market value of MiningCo's common stock on the date of the applicable grant
(except for certain 1998 options issued with exercise prices less than the
deemed fair value at the date of grant). Incentive options granted to
stockholders who own more than 10% of the outstanding stock of MiningCo must be
issued at 110% of the fair market value of the stock on the date that the
options are granted.

    outstanding stock of MiningCo.
 
    The weighted-average remaining life of the 1,128,649 options outstanding at
December 31, 1998 is 8.75 years.
 
    For the twelve months ended December 31, 1998, MiningCo recorded deferred
compensation expense of approximately $1,716,900, in connection with the grant
of certain options to employees and directors, representing the difference
between the deemed fair value of MiningCo's common stock at the date of grant
for accounting purposes and the exercise price of the related options. This
amount is presented as a reduction of stockholders equity (deficit) and
amortized over the vesting period, typically four years, of the applicable
options. MiningCo granted approximately 485,921 options at a weighted average
exercise price of $1.43 per share; all of which were granted at less than the
deemed fair value at the date of grant. MiningCo has amortized $478,000 of
deferred compensation for the year ended December 31, 1998 of which $27,000 has
been included in cost of revenues. MiningCo expects to amortize the following
amounts of deferred compensation annually: 1999--$332,000; 2000--$332,000;
2001--$332,000; and 2002--$242,900. However, $92,000 of the deferred
compensation will amortize upon the closing of a qualified initial public

acceleration clause contained within the original terms of 372,936 options under
the original option plan.
 
    In September 1997, MiningCo recorded compensation expense of approximately
$3,300 in connection with options granted to consultants to purchase 49,787
shares of common stock at an exercise price of $0.51 per share. The fair value
of the options was determined using the Black-Scholes model and the following
assumptions: risk-free interest rate of 5.7%, dividend yield of 0%, expected
life of 10 years and volatility of 0%.
 
    MiningCo also recorded compensation expense of approximately $23,000 in
connection with options granted to consultants under the Plan in December 1998
to purchase 5,340 shares of common stock at an exercise price of $4.21 per
share. The fair value of the options was determined using the Black-Scholes
model and the following assumptions: risk-free interest rate of 6.0%, dividend
yield of 0%, and volatility of 0%.
 
    Had MiningCo determined compensation expense based on the fair value on the
grant date for its stock options issued to employees under SFAS No. 123,
MiningCo's net loss would have been adjusted to the pro forma amounts indicated
below:

    The per share weighted-average fair value of stock options granted during
1997 and 1998 was $0.09 and $3.87, respectively, on the date of grant using the
Black Scholes option pricing model with the following weighted-average
assumptions for 1997 and 1998: (i) risk-free interest rate--5.7% and 6%
respectively; (ii) dividend yield--0.0% for both years; and (iii) expected
life--3.4 and 4.4 years, respectively. As permitted under the provisions of SFAS
No. 123, and based on the historical lack of a public market for MiningCo's
options, no factor for volatility has been reflected in the option pricing
calculation.

    (B) EMPLOYMENT AGREEMENTS
 
    MiningCo has employment agreements with two senior employees which provide
for severance benefits, among other items. In the event these agreements are
terminated, MiningCo may be liable for severance up to $420,000 payable during
the year following that termination.
 
(13)  SUBSEQUENT EVENTS--UNAUDITED
 
    Effective upon the closing of the IPO, MiningCo will be authorized to issue
50,000,000 shares of common stock and 5,000,000 shares of undesignated preferred
stock.
 
    During January 1999, MiningCo entered into employment arrangements with two
employees. The employment arrangements provide for minimum salary levels, and
incentive compensation and severance benefits, among other items. MiningCo
granted 133,500 options in the aggregate to the two employees. The exercise
price of the options is $4.21 per share. As a result, MiningCo expects to record
deferred compensation expense in the first quarter of 1999 relating to the
133,500 options for the difference between the deemed fair value of MiningCo's
common stock (the initial public offering price for accounting purposes) and the
exercise price of that option at the date of grant of $4.21 per share. This
amount will be presented as a reduction of stockholders' equity and amortized
over the four-year vesting period of the applicable options.
 
    In January and February 1999, MiningCo entered into a lease line of credit
for $781,300 to finance capital equipment, of which $232,200 is due in 1999,
$268,800 in 2000, $273,300 in 2001, and $7,000 in 2002. The effective interest
rate of the credit facility was 16%.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The registrant's Amended and Restated Certificate of Incorporation in effect
as of the date hereof, and the registrant's Second Amended and Restated
Certificate of Incorporation to be in effect upon the closing of this offering
(collectively, the "certificate") provides that, except to the extent prohibited
by the Delaware General Corporation Law, as amended (the "DGCL"), the
registrant's directors shall not be personally liable to the registrant or its
stockholders for monetary damages for any breach of fiduciary duty as directors
of the registrant. Under the DGCL, the directors have a fiduciary duty to the
registrant which is not eliminated by this provision of the certificate and, in
appropriate circumstances, equitable remedies such as injunctive or other forms
of nonmonetary relief will remain available. In addition, each director will
continue to be subject to liability under the DGCL for breach of the director's
duty of loyalty to the registrant, for acts or omissions which are found by a
court of competent jurisdiction to be not in good faith or involving intentional
misconduct, for knowing violations of law, for actions leading to improper
personal benefit to the director, and for payment of dividends or approval of
stock repurchases or redemptions that are prohibited by the DGCL. This provision
also does not affect the directors' responsibilities under any other laws, such
as the Federal securities laws or state or Federal environmental laws. The
registrant has applied for liability insurance for its officers and directors.
 
    Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers, provided that this provision
shall not eliminate or limit the liability of a director: (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) arising under Section 174 of the DGCL, or (iv)
for any transaction from which the director derived an improper personal
benefit. The DGCL provides further that the indemnification permitted thereunder
shall not be deemed exclusive of any other rights to which the directors and
officers may be entitled under the corporation's bylaws, any agreement, a vote
of stockholders or otherwise. The certificate eliminates the personal liability
of directors to the fullest extent permitted by Section 102(b)(7) of the
 
                                      II-1
<PAGE>
DGCL and provides that the registrant may fully indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding (whether civil, criminal, administrative or
investigative) by reason of the fact that that person is or was a director or
officer of the registrant, or is or was serving at the request of the registrant
as a director or officer of another corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise, against expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with any threatened, pending or
completed action, suit or proceeding.
 
    At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the certificate. The registrant is not aware of any
threatened litigation or proceeding that may result in a claim for any
indemnification.

ITEM 17. UNDERTAKINGS
 
    The undersigned registrant hereby undertakes to provide to the Underwriter
at the closing specified in the Underwriting Agreement, certificates in those
denominations and registered in those names as required by the Underwriter to
permit prompt delivery to each purchaser.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
this indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
those liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by that
director,
 
                                      II-4
<PAGE>
officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether this indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
that issue.
 
    The undersigned registrant hereby undertakes that:
 
        (1)  For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424 (b)(1) or
    (4), or 497(h) under the Securities Act of 1933, shall be deemed to be part
    of this registration statement as of the time it was declared effective.
 
        (2)  For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and this offering of these securities at
    that time shall be deemed to be the initial BONA FIDE offering thereof.

Dear Sirs:

            MiningCo.com, Inc., a corporation organized and existing under the
laws of the State of Delaware (the "Company"), proposes, subject to the terms
and conditions stated herein, to issue and sell to the several underwriters
named in Schedule I hereto (the "Underwriters") an aggregate of 3,000,000 shares
(the "Firm Shares") of its common stock, par value $.001 per share (the "Common
Stock"), and, for the sole purpose of covering over-allotments in connection
with the sale of the Firm Shares, at the option of the Underwriters, up to an
additional 450,000 shares (the "Additional Shares") of Common Stock. The Firm
Shares and any Additional Shares purchased by the Underwriters are referred to
herein as the "Offered Shares." The Company also proposes to issue and sell
[206,783] shares of Common Stock (the "Comcast Shares") to Comcast Interactive
Investments, Inc. ("Comcast") pursuant to a Common Stock Purchase Agreement
dated as of February 23, 1999 (the "Comcast Purchase Agreement"), between the
Company and Comcast. The Offered Shares and the Comcast Shares are collectively
referred to herein as the "Shares." The Shares are more fully described in the
Registration Statement referred to below.

      1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents
and warrants to, and agrees with, the Underwriters that:

            (a) The Company has filed with the Securities and Exchange
      Commission (the "Commission") a registration statement on Form S-1 (No.
      333-69881), and may have filed an amendment or amendments thereto, for the
      registration of the Offered Shares under the Securities Act of 1933, as
      amended (the "Act"). Such registration statement, including the
      prospectus, financial statements and schedules, exhibits and all other
      documents filed as a part thereof, as amended at the time of effectiveness
      of the registration statement, including any information deemed to be a
      part thereof as of the time of effectiveness pursuant to paragraph (b) of
      Rule 430A or Rule 434 of the Rules 


<PAGE>

      and Regulations of the Commission under the Act (the "Regulations"), is
      herein called the "Registration Statement" and the prospectus, in the form
      first filed with the Commission pursuant to Rule 424(b) of the Regulations
      or filed as part of the Registration Statement at the time of
      effectiveness if no Rule 424(b) or Rule 434 filing is required, is herein
      called the "Prospectus." The term "preliminary prospectus" as used herein
      means a preliminary prospectus as described in Rule 430 of the
      Regulations.

            (b) At the time of the effectiveness of the Registration Statement
      or the effectiveness of any post-effective amendment to the Registration
      Statement, when the Prospectus is first filed with the Commission pursuant
      to Rule 424(b) or Rule 434 of the Regulations, when any supplement to or
      amendment of the Prospectus is filed with the Commission and at the
      Closing Date and the Additional Closing Date, if any (as hereinafter
      respectively defined), the Registration Statement and the Prospectus and
      any amendments thereof and supplements thereto complied or will comply in
      all material respects with the applicable provisions of the Act and the
      Regulations and does not or will not contain an untrue statement of a
      material fact and does not or will not omit to state any material fact
      required to be stated therein or necessary in order to make the statements
      therein (i) in the case of the Registration Statement, not misleading and
      (ii) in the case of the Prospectus, in light of the circumstances under
      which they were made, not misleading. When the preliminary prospectus
      dated March 3, 1999 relating to the Offered Shares was first filed with
      the Commission (whether filed as part of the registration statement for
      the registration of the Offered Shares or any amendment thereto or
      pursuant to Rule 424(a) of the Regulations) and when any amendment thereof
      or supplement thereto was first filed with the Commission, such
      preliminary prospectus and any amendments thereof and supplements thereto
      complied in all material respects with the applicable provisions of the
      Act and the Regulations and did not contain an untrue statement of a
      material fact and did not omit to state any material fact required to be
      stated therein or necessary in order to make the statements therein in
      light of the circumstances under which they were made not misleading. No
      representation and warranty is made in this subsection (b), however, with
      respect to any information contained in or omitted from the Registration
      Statement or the Prospectus or any related preliminary prospectus or any
      amendment thereof or supplement thereto in reliance upon and in conformity
      with information furnished in writing to the Company by or on behalf of
      any Underwriter through the Representatives as herein stated expressly for
      use in connection with the preparation thereof. If Rule 434 is used, the
      Company will comply with the requirements of Rule 434.

            (c) KPMG LLP, who have certified the financial statements and
      supporting schedules included in the Registration Statement, are
      independent public accountants as required by the Act and the Regulations.

            (d) Subsequent to the respective dates as of which information is
      given in the Registration Statement and the Prospectus, except as set
      forth in the Registration Statement and the Prospectus, there has been no
      material adverse change or any development involving a prospective
      material adverse change in the business, prospects, properties,
      operations, condition (financial or other) or results of operations of the
      Company, whether or not arising from transactions in the ordinary course
      of business, 


                                       2

<PAGE>

      and since the date of the latest balance sheet presented in the
      Registration Statement and the Prospectus, the Company has not incurred or
      undertaken any liabilities or obligations, direct or contingent, whether
      or not arising from transactions in the ordinary course of business, which
      are material to the Company, except for liabilities or obligations that
      are reflected in the Registration Statement and the Prospectus.

            (e) This Agreement, the Comcast Purchase Agreement and the
      transactions contemplated herein and therein have been duly and validly
      authorized by the Company and this Agreement and the Comcast Purchase
      Agreement have been duly and validly executed and delivered by the
      Company.

            (f) The Company is not in violation of its certificate of
      incorporation or by-laws (or other organizational documents) or in default
      in the performance of any obligation, agreement or condition contained in
      any agreement, instrument, franchise, license, permit, judgment, order or
      decree to which the Company is a party or by which it or any of its
      properties or assets is bound, which default would have a material adverse
      effect on the Company's business, prospects, properties, operations,
      condition (financial or other) or results of operations (a "Material
      Adverse Effect").

            (g) The execution, delivery and performance of this Agreement and
      the Comcast Purchase Agreement and the consummation of the transactions
      contemplated hereby and thereby do not and will not (i) conflict with or
      result in a breach of any of the terms and provisions of, or constitute a
      default (or an event which with notice or lapse of time, or both, would
      constitute a default) under, or result in the creation or imposition of
      any lien, charge or encumbrance upon any property or assets of the Company
      pursuant to, any material agreement, instrument, franchise, license or
      permit to which the Company is a party or by which any of its properties
      or assets may be bound or (ii) violate or conflict with any provision of
      applicable law or the certificate of incorporation or by-laws (or other
      organizational documents) of the Company or (iii) violate or conflict with
      any judgment, decree, order, statute, rule or regulation of any court or
      any public, governmental or regulatory agency or body having jurisdiction
      over the Company or any of its properties or assets, which violation or
      conflict would have a Material Adverse Effect. No consent, approval,
      authorization, order, registration, filing, qualification, license or
      permit of or with any court or any public, governmental or regulatory
      agency or body having jurisdiction over the Company or any of its
      properties or assets is required for the execution, delivery and
      performance of this Agreement or the Comcast Purchase Agreement or the
      consummation of the transactions contemplated hereby and thereby,
      including the issuance, sale and delivery of the Shares to be issued, sold
      and delivered by the Company hereunder and thereunder, except the
      registration under the Act of the Offered Shares and such consents,
      approvals, authorizations, orders, registrations, filings, qualifications,
      licenses and permits as may be required under state securities or Blue Sky
      laws in connection with the purchase and distribution of the Offered
      Shares by the Underwriters. The issuance and sale of the Comcast Shares
      pursuant to the Comcast Purchase Agreement is exempt from the registration
      requirements of the Act by virtue of Section 4(2) of the Act.


                                       3

            (h) All of the outstanding shares of Common Stock are duly and
      validly authorized and issued, fully paid and nonassessable and were not
      issued and are not now in violation of or subject to any preemptive
      rights. The Shares, when issued, delivered and sold in accordance with
      this Agreement or the Comcast Purchase Agreement, as the case may be, will
      be duly and validly issued and outstanding, fully paid and nonassessable,
      and will not have been issued in violation of or be subject to any
      preemptive rights. The Company had, at December 31, 1998, an authorized
      and outstanding capitalization as set forth in the Registration Statement
      and the Prospectus. The Common Stock, the Firm Shares, the Additional
      Shares and the Comcast Shares conform to the descriptions thereof
      contained in the Registration Statement and the Prospectus.

            (i) The Company does not own, directly or indirectly, any stock,
      partnership interest or joint venture interest in, or any security issued
      by, any other entity.

            (j) Each promissory note issued by the Company that was convertible
      into preferred stock of the Company has, prior to the date hereof, been
      converted into such preferred stock. All of the outstanding Series A,
      Series B and Series C Convertible Preferred Stock (collectively, the
      "Preferred Stock") of the Company has been duly and validly authorized and
      is validly issued and outstanding, fully paid and nonassessable and was
      not issued in violation of any preemptive rights and the shares of Common
      Stock issuable upon conversion thereof have been duly and validly
      authorized and reserved for issuance upon such conversion and, upon
      conversion of the Preferred Stock on the Closing Date, the shares of
      Common Stock issuable upon such conversion will be validly issued and
      outstanding, fully paid and nonassessable and will not have been issued in
      violation of or be subject to any preemptive rights. All outstanding
      warrants (the "Warrants") to purchase Common Stock of the Company, have
      been duly and validly authorized, executed and delivered by the Company
      and constitute valid and binding obligations of the Company and the shares
      of Common Stock issuable upon exercise of such Warrants have been duly and
      validly authorized and reserved for issuance upon such exercise and, upon
      payment of the exercise price thereof upon exercise of such Warrants, such
      shares of Common Stock will be validly issued and outstanding, fully paid
      and nonassessable and will not have been issued in violation of or be
      subject to any preemptive rights. Except as described in or expressly
      contemplated by the Registration Statement and the Prospectus, there are
      no outstanding rights, warrants or options to acquire, or instruments
      convertible into or exchangeable for, any shares of capital stock or other
      equity interests in the Company or any of its subsidiaries, or any
      contract, commitment, agreement, understanding or arrangement (including
      without limitation preemptive rights) of any kind relating to the issuance
      of any capital stock of the Company or any such subsidiary, or any such
      convertible or exchangeable securities or any such rights, warrants or
      options.

            (k) The Company has been duly incorporated and is validly existing
      as a corporation in good standing under the laws of the state of Delaware.
      The Company is duly qualified and is in good standing as a foreign
      corporation in each jurisdiction in which the character or location of its
      properties (owned, leased or licensed) or the nature or conduct of its
      business makes such qualification necessary, except for those failures to


                                       4

<PAGE>

      be so qualified or in good standing which will not, individually or in the
      aggregate, have a Material Adverse Effect. The Company has all requisite
      corporate power and authority, and all necessary consents, approvals,
      authorizations, orders, registrations, qualifications, licenses and
      permits of and from all public, regulatory or governmental agencies and
      bodies, to own, lease and operate its properties and conduct its business
      as now being conducted and as described in the Registration Statement and
      the Prospectus, except as would not result in a Material Adverse Effect,
      and no such consent, approval, authorization, order, registration,
      qualification, license or permit contains a materially burdensome
      restriction not adequately disclosed in the Registration Statement and the
      Prospectus.

            (l) Except as described in the Prospectus, there is no litigation or
      governmental proceeding to which the Company is a party or to which any
      property of the Company is subject or which is pending or, to the
      knowledge of the Company, contemplated against the Company which, if
      determined adversely to the Company, might individually or in the
      aggregate have a Material Adverse Effect, or which is required to be
      disclosed in the Registration Statement and the Prospectus, and there are
      no statutes, regulations, contracts or other documents that are required
      to be described in the Registration Statement or the Prospectus or to be
      filed as exhibits to the Registration Statement that are not described or
      filed as required.

            (m) The Company has not taken and will not take, directly or
      indirectly, any action designed to cause or result in, or which
      constitutes or which might reasonably be expected to constitute, the
      stabilization or manipulation of the price of the shares of Common Stock
      to facilitate the sale or resale of the Offered Shares.

            (n) The financial statements, including the notes thereto, and
      supporting schedules included in the Registration Statement and the
      Prospectus present fairly the financial position of the Company as of the

      procedures), patents, copyrights, and other intellectual property
      reasonably necessary to conduct the business now operated by it, or
      presently employed by it, and has not received any notice of infringement

      in the Prospectus (exclusive of any amendments or supplements thereto
      subsequent to the date of this Agreement), the Company has not sold,

      Registration Statement and the Prospectus which is not so described.

            (aa) The merger of General Internet, Inc, a New York corporation
      ("General Internet"), with and into the Company (the "Merger") has become

      agreements herein contained, but subject to the terms and conditions
      herein set forth, the Company agrees to sell to the Underwriters and the
      Underwriters, severally and not jointly, agree to purchase from the

      for, the Firm Shares shall be made at the offices of Brobeck, Phleger &
      Harrison LLP, 1633 Broadway, 47th Floor, New York, New York 10019, or at
      such other place as shall be agreed upon by the Representatives and the
      Company, at 9:00 A.M. on the third or fourth business day (as permitted
      under Rule 15c6-1 under the Exchange Act) (unless postponed in accordance
      with the provisions of Section 9 hereof), following the date of the
      effectiveness of the Registration Statement (or, if the Company has
      elected to rely upon Rule 430A of the Regulations, the third or fourth
      business day (as permitted under Rule 15c6-1 under the Exchange Act) after
      the determination of the initial public offering price of the Offered
      Shares), such time and date of payment and delivery being herein called
      the "Closing Date." Payment shall be made to the Company by wire transfer
      in same day funds, against delivery to the Representatives for the
      respective accounts of the Underwriters of the Offered Shares to be
      purchased by them. Certificates for the Offered Shares shall be registered
      in such name or names and in such authorized denominations as the
      Representatives may request in writing at least two full business days
      prior to the Closing Date. The Company will permit you to examine and
      package such certificates for delivery at least one full business day
      prior to the Closing Date.

            (c) In addition, the Company hereby grants to the Underwriters
      options to purchase up to an aggregate of 450,000 Additional Shares at the
      same purchase price per share to be paid by the Underwriters to the
      Company for the Firm Shares as set forth in this Section 2, for the sole
      purpose of covering over-allotments in the sale of Firm Shares by the
      Underwriters. These options may be exercised at any time and from time to
      time, in whole or in part, on or before the thirtieth day following the
      date of the Prospectus, by written notice by the Representatives to the
      Company. Each such notice shall set forth the aggregate number of
      Additional Shares as to which an option is being exercised and the date
      and time, as reasonably determined by the Representatives, when the
      Additional Shares are to be delivered (each such date and time being
      herein sometimes referred to as the "Additional Closing Date"); PROVIDED,
      HOWEVER, that no Additional Closing Date shall be earlier than the Closing
      Date or earlier than the second full business day after the date on which
      the option shall have been exercised nor later than the eighth full
      business day after the date on which the option shall have been exercised
      (unless such time and date are postponed in accordance with the provisions
      of Section 9 hereof). Certificates for Additional Shares shall be
      registered in such name or names and in such authorized denominations as
      the Representatives may request in writing at least two full business days

      full business day prior to the applicable Additional Closing Date.


                                       8

<PAGE>

      The number of Additional Shares to be sold to each Underwriter on an
Additional Closing Date shall be the number which bears the same ratio to the
aggregate number of Additional Shares being purchased on such Additional Closing
Date as the number of Firm Shares set forth opposite the name of such
Underwriter in Schedule I hereto (or such number increased as set forth in
Section 9 hereof) bears to 3,000,000 subject, however, to such adjustments to
eliminate any fractional shares as the Representatives in their sole discretion
shall make.

      Payment for the Additional Shares shall be made by wire transfer in same
day funds at the offices of Brobeck, Phleger & Harrison LLP, 1633 Broadway, 47th
Floor, New York, New York 10019, or such other location as may be mutually
acceptable, upon delivery of the certificates for the Additional Shares to the
Representatives for the respective accounts of the Underwriters.

      3. OFFERING.

            (b) The Company and the Underwriters hereby agree that up to 300,000
      of the Firm Shares to be purchased by the Underwriters (the "Directed
      Shares") shall be reserved for sale by the Underwriters to eligible
      employees of and certain persons designated by the Company (the "Directed
      Shares Purchasers"), as part of the distribution of the Offered Shares by
      the Underwriters subject to the terms of this Agreement, the applicable
      rules, regulations and interpretations of the National Association of
      Securities Dealers, Inc. and all other applicable laws, rules and
      regulations, PROVIDED, HOWEVER, that under no circumstances will Bear,
      Stearns & Co. Inc. or any other Underwriter be liable to the Company or to
      any of the -------- ------- Directed Shares Purchasers for any action
      taken or omitted in good faith in connection with transactions effected
      with regard to the Directed Shares Purchasers. To the extent that such
      Directed Shares are not orally confirmed for purchase by such persons by
      the end of the first day after the date of this Agreement, such Directed
      Shares will be offered to the public as part of the underwritten offering
      contemplated hereby.

      4. COVENANTS OF THE COMPANY. The Company covenants and agrees with the
Underwriters that:

            (a) If the Registration Statement has not yet been declared
      effective, the Company will use its best efforts to cause the Registration
      Statement and any amendments thereto to become effective as promptly as
      possible, and if Rule 430A is used or the filing of the Prospectus is
      otherwise required under Rule 424(b) or Rule 434, the Company will file
      the Prospectus (properly completed if Rule 430A has been used) pursuant to
      Rule 424(b) or Rule 434 within the prescribed time period and will provide
      evidence satisfactory to the Representatives of such timely filing. If the
      Company elects to rely on Rule 434, the Company will prepare and file a
      term sheet that complies with the requirements of Rule 434.


                                       9

<PAGE>

      The Company will notify the Representatives as promptly as possible (and,
if requested by you will confirm such notice in writing) (i) when the
Registration Statement and any amendments thereto become effective, (ii) of any
request by the Commission for any amendment of or supplement to the Registration
Statement or the Prospectus or for any additional information, (iii) of the
mailing or the delivery to the Commission for filing of any amendment of or
supplement to the Registration Statement or the Prospectus, (iv) of the issuance
by the Commission of any stop order suspending the effectiveness of the
Registration Statement or any post-effective amendment thereto or of the
initiation, or the threatening, of any proceedings therefor, (v) of the receipt
of any comments from the Commission, and (vi) of the receipt by the Company of
any notification with respect to the suspension of the qualification of the
Shares for sale in any jurisdiction or the initiation or threatening of any
proceeding for that purpose. If the Commission shall propose or enter a stop
order at any time, the Company will make every reasonable effort to prevent the
issuance of any such stop order and, if issued, to obtain the lifting of such
order as soon as possible. The Company will not file any amendment to the
Registration Statement or any amendment of or supplement to the Prospectus
(including the prospectus required to be filed to Rule 424(b) or Rule 434) that
differs from the prospectus on file at the time of the effectiveness of the
Registration Statement before or after the effective date of the Registration
Statement to which the Representatives shall reasonably object in writing after
being timely furnished in advance a copy thereof.

            (b) If at any time when a prospectus relating to the Offered Shares
      is required to be delivered under the Act any event shall have occurred as
      a result of which the Prospectus as then amended or supplemented would, in
      the judgment of the Underwriters or the Company, include an untrue
      statement of a material fact or omit to state any material fact required
      to be stated in order to make any statement therein, in light of the
      circumstances under which it was made, not misleading, or if it shall be
      necessary, in the judgment of the Underwriters or the Company, at any time
      to amend or supplement the Prospectus or the Registration Statement to
      comply with the Act or the Regulations, the Company will notify the
      Representatives promptly and prepare and file with the Commission an
      appropriate amendment or supplement (in form and substance satisfactory to
      the Representatives) which will correct such statement or omission and
      will use its best efforts to have any amendment to the Registration
      Statement declared effective as soon as possible.

            (c) The Company will promptly deliver to the Representatives two
      signed copies of the Registration Statement, including exhibits and all
      amendments thereto, and the Company will promptly deliver to each of the
      Underwriters such number of copies of any preliminary prospectus, the
      Prospectus, the Registration Statement and all amendments of and
      supplements to such documents, if any, as the Representatives may
      reasonably request.

            (d) The Company will endeavor in good faith, in cooperation with the
      Representatives, at or prior to the time of effectiveness of the
      Registration Statement, to qualify the Offered Shares for offering and
      sale under the securities laws relating to the offering or sale of the
      Shares of such jurisdictions as the Representatives may designate 


                                       10

<PAGE>

      and to maintain such qualification in effect for so long as required for
      the distribution thereof, except that in no event shall the Company be
      obligated in connection therewith to qualify as a foreign corporation or
      to execute a general consent to service of process.

            (e) The Company will make generally available (within the meaning of
      11(a) of the Act) to its security holders and to the Representatives as
      soon as practicable, but not later than 45 days after the end of its
      fiscal quarter in which the first anniversary date of the effective date
      of the Registration Statement occurs, an earnings statement (in form
      complying with the provisions of Rule 158 of the Regulations) covering a
      period of at least twelve consecutive months beginning after the effective
      date of the Registration Statement.

            (f) During the period of 180 days from the date of the Prospectus,
      the Company will not, without the prior written consent of Bear, Stearns &
      Co. Inc., issue, sell, offer or agree to sell, grant any option for the
      sale of, pledge, make any short sale, establish an open "put equivalent
      position" within the meaning of Rule 16a-1(h) under the Securities
      Exchange Act of 1934, as amended, or otherwise dispose of, any Common
      Stock (or any securities convertible into, exercisable for or exchangeable
      for Common Stock) of the Company or (ii) enter into any swap, derivative
      transaction or other arrangement that transfers to another, in whole or in
      part, any of the economic consequences of ownership of the Common Stock,
      whether any such transaction described in clause (i) or (ii) above is to
      be settled by delivery of Common Stock or such other securities, in cash
      or otherwise, PROVIDED that the foregoing shall not apply to (A) the
      Shares, (B) the issuance of Common Stock upon conversion of the Preferred
      Stock on the -------- Closing Date, (C) the issuance by the Company of
      shares of Common Stock upon the exercise of any warrant outstanding on the
      date hereof and disclosed in the Prospectus, (D) the issuance by the
      Company of shares of Common Stock or options to purchase Common Stock
      pursuant to any stock option or incentive plan described in the Prospectus
      and (E) the issuance by the Company of shares of Common Stock in
      connection with any acquisition of another company if the terms of such
      issuance provide that such shares shall not be resold prior to the
      expiration of the 180-day period from the date of the Prospectus; and the
      Company will obtain the undertaking of each of its officers and directors
      and such of its stockholders as have been heretofore designated by the
      Representatives and listed on Schedule II attached hereto not to engage in
      any of the aforementioned transactions on their own behalf.

            (g) During a period of three years from the effective date of the
      Registration Statement, the Company will furnish to the Representatives,
      copies of (i) all reports to its stockholders; and (ii) all reports,
      financial statements and proxy or information statements filed by the
      Company with the Commission or any national securities exchange.

            (h) The Company will apply the proceeds from the sale of the Shares
      as set forth under "Use of Proceeds" in the Prospectus.

            (i) The Company will use its best efforts to cause the Shares to
      continue to qualify for inclusion in the Nasdaq National Market System.


                                       11
<PAGE>

            (j) The Company will use its best efforts to ensure that the
      Directed Shares are restricted as required by the National Association of
      Securities Dealers Inc. or the National Association of Securities Dealers
      Inc. rules from sale, transfer, assignment, pledge or hypothecation for a
      period of three (3) months following the date of this Agreement. The
      Underwriters will notify the Company as to which persons will need to be
      so restricted. At the request of the Underwriters, the Company will direct
      the transfer agent to place a stop transfer restriction upon such
      securities for such a period of time. Should the Company release, or seek
      to release, from such restrictions any of the Directed Shares, the Company
      agrees to reimburse the Underwriters for any reasonable expenses
      (including, without limitation, legal expenses) they incur in connection
      with such release.

      5. PAYMENT OF EXPENSES. Whether or not the transactions contemplated in
this Agreement are consummated or this Agreement is terminated, the Company
hereby agrees to pay all costs and expenses incident to the performance of the

                  (ii) The authorized capital stock of the Company is as set
            forth in the Registration Statement and the Prospectus. All of the
            outstanding shares of Common Stock (including the shares of Common
            Stock issued on the Closing Date upon conversion of the Preferred
            Stock) are duly authorized and validly issued, are fully paid and
            nonassessable and were not issued in violation of any preemptive
            rights arising under the Delaware General Corporation Law or, to
            such counsel's knowledge, similar rights that entitle or will
            entitle any person to acquire any shares of capital stock of the
            Company upon the issuance and sale of the Shares by the Company. The
            Shares to be sold by the Company on the Closing Date have been duly
            authorized and, when issued and delivered to the Underwriters or
            Comcast, as applicable, against payment therefor in accordance with
            this Agreement or the Comcast Purchase Agreement, as applicable,
            will be validly issued, fully paid and nonassessable and will not
            have been issued in violation of any preemeptive rights arising
            under the Delaware General Corporation Law or, to such counsel's
            knowledge, similar rights that entitle or will entitle any person to
            acquire any shares of capital stock of the Company upon the issuance
            and sale of the Shares by the Company. The Common Stock, the Firm
            Shares, the Additional Shares and the Comcast Shares conform as to
            legal matters to the descriptions thereof contained in the
            Registration Statement and the Prospectus.

                  (iii) All outstanding Warrants to purchase Common Stock of the
            Company have been duly authorized, executed and delivered by the
            Company and constitute 


                                       13

<PAGE>

            valid and binding obligations of the Company, enforceable against it
            in accordance with their terms, subject to applicable bankruptcy,
            insolvency, reorganization, moratorium or other similar laws
            relating to or affecting creditors' rights and remedies generally,
            and subject, as to enforceability, to general equitable principles
            (whether relief is sought in a proceeding at law or in equity) and
            except as rights to indemnification and contribution thereunder may
            be limited by applicable law or public policy relating thereto. The
            shares of Common Stock issuable upon exercise of such Warrants have
            been duly reserved for issuance upon such exercise and, upon payment
            of the exercise price thereof upon exercise of such Warrants, such
            shares of Common Stock will be validly issued and outstanding, fully
            paid and nonassessable and will be free of any preemptive rights
            arising under the Delaware General Corporation Law or, to such
            counsel's knowledge, similar rights that entitle or will entitle any
            person to acquire any shares of capital stock of the Company upon
            the issuance and sale of such shares of Common Stock by the Company.

                  (iv) This Agreement and the Comcast Purchase Agreement have
            been duly and validly authorized, executed and delivered by the
            Company.

                  (v) To such counsel's knowledge, (i) there is no litigation or
            governmental or other action, suit, proceeding or investigation
            before any court or before or by any public, regulatory or
            governmental agency or body pending or, threatened against, or
            involving the properties or business of, the Company, which is of a
            character required to be disclosed in the Registration Statement and
            the Prospectus which has not been properly disclosed therein and
            (ii) there are no statutes, regulations, contracts or other
            documents that are required to be described in the Registration
            Statement or the Prospectus or to be filed as exhibits to the
            Registration Statement that are not described or filed as required.

                  (vi) The execution, delivery and performance of this Agreement
            and the Comcast Purchase Agreement and the consummation of the
            transactions contemplated hereby and thereby by the Company do not
            and will not (A) conflict with or result in a breach of any of the
            terms and provisions of, or constitute a default (or an event which
            with notice or lapse of time, or both, would constitute a default)
            under, or result in the creation or imposition of any lien, charge
            or encumbrance upon any properties or assets of the Company pursuant
            to, any agreement, instrument, franchise, license or permit known to
            such counsel to which the Company is a party or by which any of its
            properties or assets may be bound or (B) violate or conflict with
            any provision of applicable law or the certificate of incorporation
            or by-laws (or other organizational documents) of the Company, or
            any statute, rule or regulation, or to the best knowledge of such
            counsel, any judgment, decree or order, of any court or any public,
            governmental or regulatory agency or body having jurisdiction over
            the Company or any of its properties or assets. No consent,
            approval, authorization, order, registration, filing, qualification,
            license or permit of or with any court or any public, governmental
            or regulatory agency or body having jurisdiction over the Company or
            any of its properties or assets is required for the execution,
            delivery and 


                                       14

<PAGE>

            performance of this Agreement or the Comcast Purchase Agreement or
            the consummation of the transactions contemplated hereby or thereby,
            except for (1) such as may be required under state securities or
            Blue Sky laws in connection with the purchase and distribution of
            the Offered Shares by the Underwriters (as to which such counsel
            need express no opinion) and (2) such as have been made or obtained
            under the Act. The issuance and sale of the Comcast Shares pursuant
            to the Comcast Purchase Agreement is exempt from the registration
            requirements of the Act by virtue of Section 4(2) of the Act.

                  (vii) The statements (A) in the Prospectus under the captions
            "Business-- Government Regulation and Legal Uncertainties,"
            "Management -- Employment, Severance and Other Agreements," "--1998
            Stock Option/Stock Issuance Plan," "Description of Securities" and
            "Shares Eligible for Future Sale" and (B) in the Registration
            Statement in Items 14 and 15, in each case insofar as such
            statements constitute summaries of the legal matters, documents or
            proceedings referred to therein, provide a fair summary of such
            legal matters, documents and proceedings in all material respects.

                  (viii) The Company is not, and upon consummation of the
            transactions contemplated hereby and by the Comcast Purchase
            Agreement, will not be, an "investment company" as such term is
            defined in the Investment Company Act of 1940, as amended.

                  (ix) The Registration Statement and the Prospectus and any
            amendments thereof or supplements thereto (except for the financial
            statements and the schedules and the other financial and statistical
            data included in the Registration Statement and the Prospectus, as
            to which no opinion need be rendered) comply as to form in all
            material respects with the requirements of the Act and the
            Regulations.

                  (x) The Registration Statement has been declared effective
            under the Act, and, to the knowledge of such counsel, no stop order
            suspending the effectiveness of the Registration Statement or any
            post-effective amendment thereof has been issued and no proceedings
            therefor have been initiated or threatened by the Commission and any
            required filing of the Prospectus pursuant to Rule 424(b) of the
            Regulations has been made in accordance with Rule 424(b).

                  (xi) To such counsel's knowledge, except as described in the
            Prospectus, no holder of any security of the Company has the right,
            not effectively satisfied or waived, to require inclusion of shares
            of Common Stock or any other security of the Company in the
            Registration Statement.

                  (xii) The Merger has become effective and the Corporate Rights
            of General Internet will continue in effect and be unimpaired by the
            Merger, and the Corporate Rights of General Internet have been
            merged with and into the Company, which is, as the surviving
            corporation, fully vested therewith. All consents, approvals, orders
            and authorizations of, and all registrations, 


                                       15

<PAGE>

            declarations and filings with, all persons (governmental and, to
            such counsel's knowledge, private) required to be obtained or made
            in connection with the consummation of the Merger have been so
            obtained or made. The Merger qualifies as a reorganization under the
            provisions of Section 368 of Internal Revenue Code.

      In addition, such opinion shall also contain a statement that such counsel
has participated in conferences with certain officers and representatives of the
Company, its independent public accountants, the Underwriters and the
Underwriters' counsel at which the contents of the Registration Statement and
the Prospectus and related matters were discussed. Such counsel need not,
however, pass upon, or assume any responsibility for, and such counsel may state
that it has not independently checked or verified, the accuracy, completeness or
fairness of the information contained in the Registration Statement and the
Prospectus. Such counsel shall state, however, that based upon its participation
as described in the preceding two sentences, (i) it confirms that it has no
reason to believe that the Registration Statement (other than the financial
statements, including the notes and schedules thereto, and the other financial
and statistical data included in the Registration Statement, as to which such
counsel need not express any belief), at the time the Registration Statement
became effective, contained any untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading; and (ii) it confirms that it has no reason to
believe that the Prospectus (other than the financial statements, including the
notes and schedules thereto, and the other financial and statistical data
included in the Prospectus, as to which such counsel need not express any
belief), on the date of such opinion, contains any untrue statement of a
material fact or omits to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

      In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws other than the laws of the United States, the
General Corporation Law of the State of Delaware, the laws of the State of New
York, to the extent such counsel deems proper and to the extent specified in
such opinion, if at all, upon an opinion or opinions (in form and substance
reasonably satisfactory to Underwriters' Counsel) of other counsel reasonably
acceptable to Underwriters' Counsel, familiar with the applicable laws; (B) as
to matters of fact, to the extent they deem proper, on certificates of
responsible officers of the Company and certificates or other written statements
of officers of departments of various jurisdictions having custody of documents
respecting the corporate existence or good standing of the Company, provided
that copies of any such statements or certificates shall be delivered to
Underwriters' Counsel. The opinion of such counsel for the Company shall state
that the opinion of any such other counsel is in form satisfactory to such
counsel and, in their opinion, you and they are justified in relying thereon.

      The opinion of Brobeck, Phleger & Harrison LLP described in this Section
6(b) shall be rendered to the Underwriters at the request of the Company and
shall so state therein.

            (c) All proceedings taken in connection with the sale of the Shares
      as herein contemplated and as contemplated in the Comcast Purchase
      Agreement shall be satisfactory in form and substance to you and to
      Underwriters' Counsel, and the Underwriters shall have received from said
      Underwriters' Counsel a favorable opinion, 


                                       16

<PAGE>

      dated as of the Closing Date with respect to the issuance and sale of the
      Offered Shares, the Registration Statement and the Prospectus and such
      other related matters as the Representatives may reasonably require, and
      the Company shall have furnished to Underwriters' Counsel such documents
      as they request for the purpose of enabling them to pass upon such
      matters.

            (d) At the Closing Date, you shall have received a certificate of
      the Chief Executive Officer and Chief Financial Officer of the Company,
      dated the Closing Date to the effect that (i) the condition set forth in
      subsection (a) of this Section 6 has been satisfied, (ii) as of the date
      hereof and as of the Closing Date, the representations and warranties of
      the Company set forth in Section 1 hereof are accurate, (iii)
      simultaneously with the Closing, the sale of the Comcast Shares pursuant
      to the Comcast Purchase Agreement shall have been consummated and the
      Company shall have received $2,500,000 as a result of such sale, (iv) as
      of the Closing Date, the obligations of the Company to be performed
      hereunder and under the Comcast Purchase Agreement on or prior thereto
      have been duly performed and (v) subsequent to the respective dates as of
      which information is given with the Registration Statement and the
      Prospectus, the Company has not sustained any material loss or
      interference with its business or properties from fire, flood, hurricane,
      accident or other calamity, whether or not covered by insurance, or from
      any labor dispute or any legal or governmental proceeding, and there has
      not been any material adverse change, or any development involving a
      material adverse change, in the business, prospects, properties,
      operations, condition (financial or otherwise), or results of operations
      of the Company, except in each case as described in or contemplated by the
      Prospectus.

            (e) At the time this Agreement is executed and at the Closing Date,
      you shall have received a letter from KPMG LLP, independent public
      accountants for the Company, dated, respectively, as of the date of this
      Agreement and as of the Closing Date addressed to the Underwriters and in
      form and substance satisfactory to the Representatives, to the effect
      that: (i) they are independent certified public accountants with respect
      to the Company within the meaning of the Act and the Regulations and
      stating that the answer to Item 10 of the Registration Statement is
      correct insofar as it relates to them; (ii) stating that, in their
      opinion, the financial statements and schedules of the Company included in
      the Registration Statement and the Prospectus and covered by their opinion
      therein comply as to form in all material respects with the applicable
      accounting requirements of the Act and the applicable published rules and
      regulations of the Commission thereunder; (iii) on the basis of procedures
      consisting of a reading of the latest available unaudited interim
      consolidated financial statements of the Company, a reading of the minutes
      of meetings and consents of the stockholders and board of directors of the
      Company and the committees of such board subsequent to December 31, 1998,
      inquiries of officers and other employees of the Company who have
      responsibility for financial and accounting matters of the Company and its
      subsidiaries with respect to transactions and events subsequent to
      December 31, 1998 and other specified procedures and inquiries to a date
      not more than five days (three days in the case of the letter delivered on
      the Closing Date) prior to the date of such letter, nothing has come to
      their attention that would cause them to believe that: (A) the unaudited
      consolidated financial statements and schedules of the Company presented
      in the Registration Statement and the 


                                       17

<PAGE>

      Prospectus do not comply as to form in all material respects with the
      applicable accounting requirements of the Act and the applicable published
      rules and regulations of the Commission thereunder or that such unaudited
      consolidated financial statements are not fairly presented in conformity
      with generally accepted accounting principles applied on a basis
      substantially consistent with that of the audited consolidated financial
      statements of the Company included in the Registration Statement and the
      Prospectus; (B) with respect to the period subsequent to December 31, 1998
      there were, as of the date of the most recent available monthly financial
      statements of the Company and as of a specified date not more than five
      days (three days in the case of the letter delivered on the Closing Date)
      prior to the date of such letter, any changes in the capital stock or
      long-term indebtedness of the Company or any decrease in the net current
      assets or stockholders' equity of the Company, in each case, as compared
      with the amounts shown in the most recent balance sheet presented in the
      Registration Statement and the Prospectus, except for changes or decreases
      which the Registration Statement and the Prospectus disclose have occurred
      or may occur or which are set forth in such letter or (C) that during the
      period from January 1, 1999 to the date of the most recent available
      monthly financial statements of the Company and to a specified date not
      more than five days (three days in the case of the letter delivered on the
      Closing Date) prior to the date of such letter, there was (1) any
      decrease, as compared with the corresponding period in the prior fiscal
      year, in total revenues, or any increase, as compared with the
      corresponding period in the prior fiscal year, in operating loss or the
      total or per share net loss or (2) any decrease, as compared with the
      corresponding period in the prior fiscal quarter, in revenues, except in
      any such case for decreases or increases which the Registration Statement
      and the Prospectus disclose have occurred or may occur or which are set
      forth in such letter; (iv) nothing has come to their attention that would
      cause them to believe that the pro forma financial information included in
      the Registration Statement do not comply in all material respects with the
      applicable accounting requirements of Rule 11-02 of Regulation S-X or that
      the pro forma adjustments have not been properly applied to the historical
      amounts in the compilation of such financial information; and (v) stating
      that they have compared specific dollar amounts, numbers of shares,
      percentages of revenues and earnings, and other financial information
      pertaining to the Company set forth in the Registration Statement and the
      Prospectus, which have been specified by the Representatives prior to the
      date of this Agreement, to the extent that such amounts, numbers,
      percentages and information may be derived from the general accounting and
      financial records of the Company or from schedules furnished by the
      Company, and excluding any questions requiring an interpretation by legal
      counsel, with the results obtained from the application of specified
      readings, inquiries and other appropriate procedures specified by the
      Representatives set forth in such letter, and found them to be in
      agreement.

            (f) Prior to the Closing Date, the Company shall have furnished to
      you such further information, certificates and documents as you may
      reasonably request.

            (g) The Representatives shall have received from each person who is
      a director or officer of the Company or stockholder that has been
      heretofore designated by the Representatives and listed on Schedule II
      hereto an agreement to the effect that such person will not, directly or
      indirectly, without the prior written consent of Bear, Stearns

      whether any such transaction described in clause (i) or (ii) above is to
      be settled by delivery of Common Stock or such other securities, in cash
      or otherwise, for a period of 180 days after the date of the Prospectus.

      If any of the conditions specified in this Section 6 shall not have been
fulfilled when and as required by this Agreement, or if any of the certificates,
opinions, written statements or letters furnished to you or to Underwriters'
Counsel pursuant to this Section 6 shall not be in all material respects
reasonably satisfactory in form and substance to the Representatives and to
Underwriters Counsel, all obligations of the Underwriters hereunder may be
cancelled by the Representatives at, or at any time prior to, the Closing Date
and the obligations of the Underwriters to purchase the Additional Shares may be

      7. INDEMNIFICATION.

            (a) The Company agrees to indemnify and hold harmless each
      Underwriter and each person, if any, who controls any Underwriter within
      the meaning of Section 15 of the Act or Section 20(a) of the Securities
      Exchange Act of 1934, as amended (the "Exchange Act"), against any and all
      losses, liabilities, claims, damages and expenses whatsoever as incurred
      (including but not limited to attorneys' fees and any and all expenses
      whatsoever incurred in investigating, preparing or defending against any
      litigation, commenced or threatened, or any claim whatsoever, and any and
      all amounts paid in settlement of any claim or litigation), joint or
      several, to which they or any of them may become subject under the Act,
      the Exchange Act or otherwise, insofar as such losses, liabilities,
      claims, damages or expenses (or actions in respect thereof) arise out of
      or are based upon any untrue statement or alleged untrue statement of a
      material fact contained in the registration statement for the registration
      of the Offered Shares, as originally filed or any amendment thereof, or
      any related preliminary prospectus or the Prospectus, or in any supplement
      thereto or amendment thereof, or arise out of or are based upon the
      omission or alleged omission to state therein a material fact required to
      be stated therein or necessary to make the statements therein not
      misleading; PROVIDED, HOWEVER, that the Company will not be liable in any
      such case to the extent but only to 


                                       19

<PAGE>

      the extent that any such loss, liability, claim, damage or expense arises
      out of or is based upon any such untrue statement or alleged untrue
      statement or omission or alleged omission made therein in reliance upon
      and in conformity with written information furnished to the Company by or
      on behalf of any Underwriter through the Representatives expressly for use
      therein. This indemnity agreement will be in addition to any liability
      which the Company may otherwise have, including under this Agreement.

            (b) Each Underwriter severally, and not jointly, agrees to indemnify
      and hold harmless the Company, each of the directors of the Company, each
      of the officers of the Company who shall have signed the Registration
      Statement, and each other person, if any, who controls the Company within
      the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act,
      against any losses, liabilities, claims, damages and expenses whatsoever
      as incurred (including but not limited to attorneys' fees and any and all
      expenses whatsoever incurred in investigating, preparing or defending
      against any litigation, commenced or threatened, or any claim whatsoever,
      and any and all amounts paid in settlement of any claim or litigation),
      jointly or severally, to which they or any of them may become subject
      under the Act, the Exchange Act or otherwise, insofar as such losses,
      liabilities, claims, damages or expenses (or actions in respect thereof)
      arise out of or are based upon any untrue statement or alleged untrue
      statement of a material fact contained in the registration statement for
      the registration of the Shares, as originally filed or any amendment
      thereof, or any related preliminary prospectus or the Prospectus, or in
      any amendment thereof or supplement thereto, or arise out of or are based
      upon the omission or alleged omission to state therein a material fact
      required to be stated therein or necessary to make the statements therein
      not misleading, in each case to the extent, but only to the extent, that
      any such loss, liability, claim, damage or expense arises out of or is
      based upon any such untrue statement or alleged untrue statement or
      omission or alleged omission made therein in reliance upon and in
      conformity with written information furnished to the Company by or on
      behalf of any Underwriter through the Representatives expressly for use
      therein; PROVIDED, HOWEVER, that in no case shall any Underwriter be
      liable or responsible for any amount in excess of the underwriting
      discount applicable to the Shares purchased by such Underwriter hereunder.
      This indemnity will be in addition to any liability which any Underwriter
      may otherwise have, including under this Agreement. The Company
      acknowledges that the statements set forth in the third, seventh and
      twelfth paragraphs under the caption "Underwriting" in the Prospectus
      constitute the only information furnished in writing by or on behalf of
      any Underwriter expressly for use in the registration statement relating
      to the Offered Shares as originally filed or in any amendment thereof, any
      related preliminary prospectus or the Prospectus or in any amendment
      thereof or supplement thereto, as the case may be.

            (c) In connection with the offer and sale of the Directed Shares,
      the Company agrees, promptly upon a request in writing, to indemnify and
      hold harmless the Underwriters from and against any and all losses,
      liabilities, claims, damages and expenses incurred by them as a result of
      the failure of the Directed Shares Purchasers to pay for and accept
      delivery of the Directed Shares which, by the end of the day following the
      date of this Agreement, were subject to a properly confirmed agreement to
      purchase such Directed Shares.


                                       20

            (d) Promptly after receipt by an indemnified party under subsection
      (a) or (b) above of notice of the commencement of any action, such
      indemnified party shall, if a claim in respect thereof is to be made
      against the indemnifying party under such subsection, notify each party
      against whom indemnification is to be sought in writing of the
      commencement thereof (but the failure so to notify an indemnifying party
      shall not relieve it from any liability which it may have under this
      Section 7). In case any such action is brought against any indemnified
      party, and it notifies an indemnifying party of the commencement thereof,
      the indemnifying party will be entitled to participate therein, and to the
      extent it may elect by written notice delivered to the indemnified party
      promptly after receiving the aforesaid notice from such indemnified party,
      to assume the defense thereof with counsel satisfactory to such
      indemnified party. Notwithstanding the foregoing, the indemnified party or
      parties shall have the right to employ its or their own counsel in any
      such case, but the fees and expenses of such counsel shall be at the
      expense of such indemnified party or parties unless (i) the employment of
      such counsel shall have been authorized in writing by one of the
      indemnifying parties in connection with the defense of such action, (ii)
      the indemnifying parties shall not have employed counsel to have charge of
      the defense of such action within a reasonable time after notice of
      commencement of the action, or (iii) such indemnified party or parties
      shall have reasonably concluded that there may be defenses available to it
      or them which are different from or additional to those available to one
      or all of the indemnifying parties (in which case the indemnifying parties
      shall not have the right to direct the defense of such action on behalf of
      the indemnified party or parties), in any of which events such fees and
      expenses shall be borne by the indemnifying parties. Anything in this
      subsection to the contrary notwithstanding, an indemnifying party shall
      not be liable for any settlement of any claim or action effected without
      its written consent; PROVIDED, HOWEVER, that -------- ------- such consent
      was not unreasonably withheld.

      8. CONTRIBUTION. In order to provide for contribution in circumstances in
which the indemnification provided for in Section 7 hereof is for any reason
held to be unavailable from any indemnifying party or is insufficient to hold
harmless a party indemnified thereunder, the Company, and the Underwriters shall
contribute to the aggregate losses, claims, damages, liabilities and expenses of
the nature contemplated by such indemnification provision (including any
investigation, legal and other expenses incurred in connection with, and any
amount paid in settlement of, any action, suit or proceeding or any claims
asserted, but after deducting in the case of losses, claims, damages,
liabilities and expenses suffered by the Company any contribution received by
the Company from persons, other than the Underwriters, who may also be liable
for contribution, including persons who control the Company within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act, officers of the
Company who signed the Registration Statement and directors of the Company) as
incurred to which the Company, and one or more of the Underwriters may be
subject, in such proportions as is appropriate to reflect the relative benefits
received by the Company and the Underwriters from the offering of the Offered
Shares or, if such allocation is not permitted by applicable law or
indemnification is not available as a result of the indemnifying party not
having received notice as provided in Section 7 hereof, in such proportion as is
appropriate to reflect not only the relative benefits referred to above but also
the relative fault of the Company and the Underwriters in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative benefits received 


                                       21

<PAGE>

by the Company and the Underwriters shall be deemed to be in the same proportion
as (x) the total proceeds from the offering of the Offered Shares (net of
underwriting discounts and commissions but before deducting expenses) received
by the Company and (y) the underwriting discounts and commissions received by
the Underwriters, respectively, in each case as set forth in the table on the
cover page of the Prospectus. The relative fault of the Company and of the
Underwriters shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or the Underwriters and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.
The Company and the Underwriters agree that it would not be just and equitable
if contribution pursuant to this Section 8 were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this Section 8, (i) in no case shall any Underwriter be liable or responsible
for any amount in excess of the underwriting discount applicable to the Shares
purchased by such Underwriter hereunder, and (ii) no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. Notwithstanding the provisions of this Section 8 and the
preceding sentence, no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Offered Shares
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages that such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. For purposes of this Section 8, each person, if any, who
controls an Underwriter within the meaning of Section 15 of the Act or Section
20(a) of the Exchange Act shall have the same rights to contribution as such
Underwriter, and each person, if any, who controls the Company within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each
officer of the Company who shall have signed the Registration Statement and each
director of the Company shall have the same rights to contribution as the
Company, subject in each case to clauses (i) and (ii) of this Section 8. Any
party entitled to contribution will, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim for contribution may be made against another party or parties,
notify each party or parties from whom contribution may be sought, but the
omission to so notify such party or parties shall not relieve the party or
parties from whom contribution may be sought from any obligation it or they may
have under this Section 8 or otherwise. No party shall be liable for
contribution with respect to any action or claim settled without its consent;
PROVIDED, HOWEVER, that such consent was not unreasonably withheld.

      9. DEFAULT BY AN UNDERWRITER.

            (a) If any Underwriter or Underwriters shall default in its or their
      obligation to purchase Firm Shares or Additional Shares hereunder, and if
      the Firm Shares or Additional Shares with respect to which such default
      relates do not (after giving effect to arrangements, if any, made by you
      pursuant to subsection (b) below) exceed in the aggregate 10% of the
      number of Firm Shares or Additional Shares, to which the default relates
      shall be purchased by the non-defaulting Underwriters in proportion to the
      respective proportions which the numbers of Firm Shares set forth opposite
      their 


                                       22

<PAGE>

      respective names in Schedule I hereto bear to the aggregate number of Firm
      Shares set forth opposite the names of the non-defaulting Underwriters.

            (b) In the event that such default relates to more than 10% of the
      Firm Shares or Additional Shares, as the case may be, the Representatives
      may in their discretion arrange for the Representatives or for another
      party or parties (including any non-defaulting Underwriter or Underwriters
      who so agree) to purchase such Firm Shares or Additional Shares, as the
      case may be, to which such default relates on the terms contained herein.
      In the event that within five calendar days after such a default the
      Representatives do not arrange for the purchase of the Firm Shares or
      Additional Shares, as the case may be, to which such default relates as
      provided in this Section 9, this Agreement or, in the case of a default
      with respect to the Additional Shares, the obligations of the Underwriters
      to purchase and of the Company to sell the Additional Shares shall
      thereupon terminate, without liability on the part of the Company with
      respect thereto (except in each case as provided in Section 5, 7(a) and 8
      hereof) or the Underwriters, but nothing in this Agreement shall relieve a
      defaulting Underwriter or Underwriters of its or their liability, if any,
      to the other Underwriters and the Company for damages occasioned by its or
      their default hereunder.

            (c) In the event that the Firm Shares or Additional Shares to which
      the default relates are to be purchased by the non-defaulting
      Underwriters, or are to be purchased by another party or parties as
      aforesaid, the Representatives or the Company shall have the right to
      postpone the Closing Date or the applicable Additional Closing Date, as
      the case may be, for a period, not exceeding five business days, in order
      to effect whatever changes may thereby be made necessary in the
      Registration Statement or the Prospectus or in any other documents and
      arrangements, and the Company agrees to file promptly any amendment or
      supplement to the Registration Statement or the Prospectus which, in the
      opinion of Underwriters' Counsel, may thereby be made necessary or
      advisable. The term "Underwriter" as used in this Agreement shall include
      any party substituted under this Section 9 with like effect as if it had
      originally been a party to this Agreement with respect to such Firm Shares
      and Additional Shares.

      10. SURVIVAL OF REPRESENTATIONS AND AGREEMENTS. All representations and
warranties, covenants and agreements of the Underwriters and the Company
contained in this Agreement, including the agreements contained in Section 5,
the indemnity agreements contained in Section 7 and the contribution agreements
contained in Section 8, shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of any Underwriter or any
controlling person thereof or by or on behalf of the Company, any of its
officers and directors or any controlling person thereof, and shall survive
delivery of and payment for the Shares to and by the Underwriters. The
representations contained in Section 1 and the agreements contained in Sections
5, 7, 8 and 11(d) hereof shall survive the termination of this Agreement,
including termination pursuant to Section 9 or 11 hereof.

      11. EFFECTIVE DATE OF AGREEMENT; TERMINATION.

            (a) This Agreement shall become effective upon the later of when (i)
      the Representatives and the Company shall have received notification of
      the effectiveness of the Registration Statement and (ii) the execution of
      this Agreement. If either the initial public offering price or the
      purchase price per Offered Share has not been agreed upon prior to 5:00
      P.M., New York time, on the fifth full business day after the Registration
      Statement shall have become effective, this Agreement shall thereupon
      terminate without liability to the Company or the Underwriters except as
      herein expressly provided. Until this Agreement becomes effective as
      aforesaid, it may be terminated by the Company by notifying you or by the
      Representatives notifying the Company. Notwithstanding the foregoing, the
      provisions of this Section 11 and of Section 1, 5, 7 and 8 hereof shall at
      all times be in full force and effect.

            (b) You shall have the right to terminate this Agreement at any time
      prior to the Closing Date or the obligations of the Underwriters to
      purchase Additional Shares at any time prior to the applicable Additional
      Closing Date, as the case may be, if (A) any domestic or international
      event or act or occurrence has materially disrupted, or in the opinion of
      the Representatives will in the immediate future materially disrupt, the
      market for the Company's securities or securities in general; or (B) if
      trading on the New York Stock Exchange or the Nasdaq Stock Market shall
      have been suspended, or minimum or maximum prices for trading shall have
      been fixed, or maximum ranges for prices for securities shall have been
      required, on the New York Stock Exchange or the Nasdaq Stock Market by the
      New York Stock Exchange, the National Association of Securities Dealers,
      Inc. or by order of the Commission or any other governmental authority
      having jurisdiction; or (C) if a banking moratorium has been declared by a
      state or federal authority or if any new restriction materially adversely
      affecting the distribution of the Firm Shares or the Additional Shares, as
      the case may be, shall have become effective; or (D) (i) if the United
      States becomes engaged in hostilities or there is an escalation of
      hostilities involving the United States or there is a declaration of a
      national emergency or war by the United States or (ii) if there shall have
      been such change in political, financial or economic conditions, if the
      effect of any such event in (i) or (ii) as in the judgment of the
      Representatives makes it impracticable or inadvisable to proceed with the
      offering, sale and delivery of the Firm Shares or the Additional Shares,
      as the case may be, on the terms contemplated by the Prospectus.

            (c) Any notice of termination pursuant to this Section 11 shall be
      by telephone, telex or telegraph, confirmed in writing by letter.

            (d) If this Agreement shall be terminated pursuant to any of the
      provisions hereof (otherwise than pursuant to (i) notification by the
      Representatives as provided in Section 11(a) hereof or (ii) Section 9(b)
      or 11(b) hereof), or if the sale of the Offered Shares provided for herein
      is not consummated because any condition to the obligations of the
      Underwriters set forth herein is not satisfied or because of any refusal,
      inability or failure on the part of the Company to perform any agreement
      herein or comply with any provision hereof, the Company will, subject to
      demand by the Representatives, reimburse 


                                       24

                    CORPORATION LAW OF THE STATE OF DELAWARE

          MiningCo.com, Inc. (the "Corporation"), a corporation organized and

               Each 2.809 shares of the Corporation's Common Stock, par value 
      $.001 per share, issued and outstanding immediately prior to 6:00 P.M. on
      a date prior to the initial public offering of the Corporation's common
      stock, as determined by the officers of the Corporation, shall be

      Stock issued and outstanding is hereby converted and reclassified. No
      fractional interests resulting from such conversion shall be issued but,
      in lieu thereof, the Corporation will round the number of shares of the
      Corporation's Common Stock issuable to each holder up to the nearest whole
      share of Common Stock.

            The purpose of the Corporation is to engage in any lawful act or

                                   ARTICLE IV

                                  Capital Stock

      A.    CLASSES OF STOCK. The Corporation is authorized to issue two 
classes of stock to be designated, respectively, "Common Stock" and 
"Preferred Stock." The total number of shares which the Corporation is 
authorized to issue is 55,000,000 shares. 50,000,000 shares, par value $0.001 
per share, shall be Common Stock and 5,000,000 shares, par value $0.001 per 
share, shall be Preferred Stock. The consideration for the issuance of the 
shares shall be paid to or received by the Corporation in full before their 
issuance and shall not be less than the par value per share. The number of 
authorized shares of Common Stock may be increased or decreased (but not 
below the number of shares thereof then outstanding) by the affirmative vote 
of the holders of a majority of the stock of the Corporation entitled to 
vote, irrespective of the provisions of Section 242(b)(2) of the General 
Corporation Law of Delaware.

      B.    COMMON STOCK.

            (1) GENERAL. All shares of Common Stock will be identical and will
entitle the holders thereof to the same rights, powers and privileges. The
rights, powers and privileges of the holders of the Common Stock are subject to
and qualified by the rights of holders of any then outstanding Preferred Stock.

            (2) DIVIDENDS. Dividends may be declared and paid on the Common
Stock from funds lawfully available therefor as and when determined by the Board
of Directors and subject to any preferential dividend rights of any then
outstanding Preferred Stock.


<PAGE>

            (3) DISSOLUTION, LIQUIDATION OR WINDING UP. In the event of any
dissolution, liquidation or winding up of the affairs of the Corporation,
whether voluntary or involuntary, each issued and outstanding share of Common
Stock shall entitle the holder thereof to receive an equal portion of the net
assets of the Corporation available for distribution to the holders of Common
Stock, subject to any preferential rights of any then outstanding Preferred
Stock.

            (4) VOTING RIGHTS. Except as otherwise required by law or this
Amended and Restated Certificate of Incorporation, each holder of Common Stock
shall have one vote in respect of each share of stock held of record by such
holder on the books of the Corporation for the election of directors and on all
matters submitted to a vote of stockholders of the Corporation. Except as
otherwise required by law or provided herein, holders of Preferred Stock shall
vote together with holders of Common Stock as a single class, subject to any
special or preferential voting rights of any then outstanding Preferred Stock.
There shall be no cumulative voting.

            (5) REDEMPTION. The Common Stock is not redeemable.

            C. PREFERRED STOCK. The Board of Directors is authorized, subject to
limitations prescribed by law, by the rules of a national securities exchange,
if applicable, and by the provisions of this ARTICLE IV, to provide for the
issuance of the shares of Preferred Stock in series, and by filing a certificate
pursuant to the applicable law of the State of Delaware, to establish from time
to time the number of shares to be included in each such series, and to fix the
designation, powers, preferences, and rights of the shares of each such series
and the qualifications, limitations or restrictions thereof.

            The authority of the Board with respect to each series shall
include, but not be limited to, determination of the following:

            (1) The number of shares constituting that series and the
distinctive designation of that series;

            (2) The dividend rate on the shares of that series, whether
dividends shall be cumulative, and, if so, from which date or dates, and the
relative rights of priority, if any, of payment of dividends on shares of that
series;

            (3) Whether that series shall have voting rights, in addition to the
voting rights provided by law, and, if so, the terms of such voting rights;

            (4) Whether that series shall have conversion privileges, and, if
so, the terms and conditions of such conversion, including provision for
adjustment of the conversion rate in such events as the Board of Directors shall
determine;

            (5) Whether or not the shares of that series shall be redeemable,
and, if so, the terms and conditions of such redemption, including the date or
dates upon or after which they shall be redeemable, and the amount per share
payable in case of redemption, which amount may vary under different conditions
and at different redemption dates;


<PAGE>

            (6) Whether that series shall have a sinking fund for the redemption
or purchase of shares of that series, and, if so, the terms and amount of such
sinking fund;

            (7) The rights of the shares of that series in the event of
voluntary or involuntary liquidation, dissolution or winding up of the
Corporation, and the relative rights or priority, if any, of payment of shares
of that series; and

            (8) Any other relative rights, preferences and limitations of that
series.

            Dividends on outstanding shares of Preferred Stock shall be paid or
declared and set apart for payment before any dividends shall be paid or
declared and set apart for payment on the Common Stock with respect to the same
dividend period.

            If upon any voluntary or involuntary liquidation, dissolution or
winding up of the Corporation, the assets available for distribution to holders
of shares of Preferred Stock of all series shall be insufficient to pay such
holders the full preferential amount to which they are entitled, then such
assets shall be distributed ratably among the shares of all series of Preferred
Stock in accordance with the respective preferential amounts (including unpaid
cumulative dividends, if any) payable with respect thereto.

            D. PREEMPTIVE RIGHTS. No holder of any of the shares of any class or
series of stock or of options, warrants or other rights to purchase shares of
any class or series of stock or of other securities of the Corporation shall
have any preemptive right to purchase or subscribe for any unissued stock of any
class or series, or any unissued bonds, certificates of indebtedness, debentures
or other securities convertible into or exchangeable for stock of any class or
series or carrying any right to purchase stock of any class or series; but any
such unissued stock, bonds, certificates or indebtedness, debentures or other
securities convertible into or exchangeable for stock or carrying any right to
purchase stock may be issued pursuant to resolution of the Board of Directors of
the Corporation to such persons, firms, corporations or associations, whether or
not holders thereof, and upon such terms as may be deemed advisable by the Board
of Directors in the exercise of its sole discretion.


                                    ARTICLE V

                                    Directors

            A. NUMBER. The number of directors of the Corporation shall be such
number, not less than five (5) nor more than fifteen (15) (exclusive of
directors, if any, to be elected by holders of preferred stock of the
Corporation, voting separately as a class), as shall be set forth from time to
time in the bylaws. Vacancies in the Board of Directors of the Corporation,
however caused, and newly created directorships shall be filled by a vote of a
majority of the directors then in office, whether or not a quorum, and any
director so chosen shall hold office for a term expiring at the annual meeting
of stockholders at which the term of the class to which the director has been
chosen expires and when the director's successor is elected and qualified.


<PAGE>

            B. REMOVAL OF DIRECTORS. Notwithstanding any other provisions of
this Certificate or the By-laws of the Corporation, any director or the entire
Board of Directors of the Corporation may be removed, at any time, but only for
cause and only by the affirmative vote of the holders of not less than 66.67% of
the outstanding shares of capital stock of the Corporation entitled to vote
generally in the election of directors (considered for this purpose as one
class) cast at a meeting of the stockholders called for that purpose.
Notwithstanding the foregoing, whenever the holders of any one or more series of
preferred stock of the Corporation shall have the right, voting separately as a
class, to elect one or more directors of the Corporation, the preceding
provisions of this ARTICLE V shall not apply with respect to the director or
directors elected by such holders of preferred stock.



                                   ARTICLE VI

                              Stockholder Meetings

            Meetings of stockholders may be held within or without the State of
Delaware, as the By-laws may provide. The books of the Corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the By-laws of the Corporation. The stockholders of the
Corporation may not take any action by written consent in lieu of a meeting.



                                   ARTICLE VII

                       Limitation of Directors' Liability

            Except to the extent that the General Corporation Law of Delaware
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty, no director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, notwithstanding any provision of law imposing such
liability. If the General Corporation Law is amended after approval by the
stockholders of this ARTICLE VII to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of a director of the Corporation shall be eliminated or limited to the fullest
extent permitted by the General Corporation Law of the State of Delaware, as so
amended. No amendment to or repeal of this provision shall apply to or have any
effect on the liability or alleged liability of any director of the Corporation
for or with respect to any acts or omissions of such director occurring prior to
such amendment.



                                  ARTICLE VIII

                                 Indemnification


<PAGE>

            The Corporation may, to the fullest extent permitted by Section 145
of the General Corporation Law of Delaware, as amended from time to time,
indemnify each person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that he
is or was, or has agreed to become, a director or officer of the Corporation, or
is or was serving, or has agreed to serve, at the request of the Corporation, as
a director, officer or trustee of, or in a similar capacity with, another
corporation, partnership, joint venture, trust or other enterprise (including
any employee benefit plan) (all such persons being referred to hereafter as an
"Indemnitee"), or by reason of any action alleged to have been taken or omitted
in such capacity, against all expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by him or
on his behalf in connection with such action, suit or proceeding and any appeal
therefrom. Indemnification may include payment by the Corporation of expenses in
defending an action or proceeding in advance of the final disposition of such
action or proceeding upon receipt of an undertaking by the Indemnitee to repay
such payment if it is ultimately determined that such person is not entitled to
indemnification under this ARTICLE VIII, which undertaking may be accepted
without reference to the financial ability of such person to make such
repayment.

            The Corporation shall not indemnify any such person seeking
indemnification in connection with a proceeding (or part thereof) initiated by
such person unless the initiation thereof was approved by the Board of Directors
of the Corporation.

            The indemnification rights provided in this ARTICLE VIII (i) shall
not be deemed exclusive of any other rights to which Indemnitees may be entitled
under any law, agreement or vote of stockholders or disinterested directors or
otherwise, and (ii) shall inure to the benefit of the heirs, executors and
administrators of such persons. The Corporation may, to the extent authorized
from time to time by its Board of Directors, grant indemnification rights to
other employees or agents of the Corporation or other persons serving the
Corporation and such rights may be equivalent to, or greater or less than, those
set forth in this ARTICLE VIII.



                                   ARTICLE IX

                               Amendment of Bylaws

            In furtherance of and not in limitation of powers conferred by
statute, the Board of Directors of the Corporation is expressly authorized to
adopt, repeal, alter, amend and rescind the bylaws of the Corporation by vote of
66.67% of the Board of Directors.


<PAGE>

                                    ARTICLE X

                            Amendment of Certificate

            The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this Second Amended and Restated Certificate of
Incorporation, in the manner now or hereafter prescribed by statute and this
Second Amended and Restated Certificate of Incorporation, and all rights
conferred upon stockholders herein are granted subject to this reservation.
Notwithstanding the foregoing, the provisions set forth in ARTICLES VII, VIII,
IX and this ARTICLE X may not be repealed, altered, amended or rescinded in any
respect unless the same is approved by the affirmative vote of the holders of
not less than 66.67% of the outstanding shares of capital stock of the
Corporation entitled to vote generally in the election of directors (considered
for this purpose as a single class) cast at a meeting of the stockholders called
for that purpose (provided that notice of such proposed repeal, alteration,
amendment or rescission is included in the notice of such meeting).

                                    *  *  *


            FOURTH: That said amendments were duly adopted in accordance with
the provisions of Section 242 and 245 of the General Corporation Law.

meeting, (b) by or at the direction of the Board of Directors or (c) by any
stockholder of the Corporation who was a stockholder of record at the time of
giving of notice provided for in this Section 11, who is entitled to vote at the
meeting and who complies with the notice procedures set forth in this Section
11.

          2. For nominations or other business to be properly brought before an
annual meeting by a stockholder pursuant to clause (c) of paragraph (a)(1) of
this Section 11, the stockholder must have given timely notice thereof in
writing to the Secretary of the Corporation and such other business must
otherwise be a proper matter for stockholder action. To be timely, a
stockholder's notice shall be delivered to the Secretary at the principal
executive offices of the Corporation not later than the close of business on the
one hundred twentieth (120th) day nor earlier than the close of business on the
one hundred fiftieth (150th) day prior to the first anniversary of the date of
the proxy statement delivered to stockholders in connection with the preceding
year's annual meeting; provided, however, that if either (i) the date of the
annual meeting is more than thirty (30) days before or more than sixty (60) days
after such an anniversary date or (ii) no proxy statement was delivered to
stockholders in connection with the preceding year's annual meeting, notice by
the stockholder to be timely must be so delivered not earlier than the close of
business on the ninetieth (90th) day prior to such annual meeting and not later
than the close of business on the later of the sixtieth (60th) day prior to such
annual meeting or the close of business on the tenth (10th) day following the
day on which public announcement of the date of such meeting is first made by
the Corporation. Such stockholder's notice shall set forth (a) as to each person
whom the stockholder proposes to nominate for election or reelection as a
director, all information relating to such person that is required to be
disclosed in solicitations of proxies for election of directors, or is otherwise
required, in each case pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (the "Exchange Act") (including such person's written
consent to being named in the proxy statement as a nominee and to serving as a
director it elected); (b) as to any other business that the stockholder proposes
to bring before the meeting, a brief description of the business desired to be
brought before the meeting, the reasons for conducting such business at the
meeting and any material interest in such business of such stockholder and the
beneficial owner, if any, on whose behalf the proposal is made; and (c) as to
the stockholder giving the notice and the beneficial owner, if any, on whose
behalf the nomination or proposal is made (i) the name and address of such
stockholder, as they appear on the Corporation's books, and of such beneficial
owner and (ii) the class and number of shares of capital stock of the
Corporation that are owned beneficially and held of record by such stockholder
and such beneficial owner.

          3. Notwithstanding anything in the second sentence of paragraph (a)(2)
of this Section 11 to the contrary, in the event that the number of directors to
be elected to 


                                       3

<PAGE>

the Board of Directors of the Corporation is increased and there is no public
announcement by the Corporation naming all of the nominees for director or
specifying the size of the increased Board of Directors at least seventy (70)
days prior to the first anniversary of the preceding year's annual meeting (or,
if the annual meeting is held more than thirty (30) days before or sixty (60)
days after such anniversary date, at least seventy (70) days prior to such
annual meeting), a stockholder's notice required by this Section 11 shall also
be considered timely, but only with respect to nominees for any new positions
created by such increase, if it shall be delivered to the Secretary at the
principal executive office of the Corporation not later than the close of
business on the tenth (10th) day following the day on which such public
announcement is first made by the Corporation.

      B.  SPECIAL MEETINGS OF STOCKHOLDERS. Only such business shall be
conducted at a special meeting of stockholders as shall have been brought before
the meeting pursuant to the Corporation's notice of meeting. Nominations of
persons for election to the Board of Directors may be made at a special meeting
of stockholders at which directors are to be elected pursuant to the
Corporation's notice of meeting (a) by or at the direction of the Board of
Directors or (b) provided that the Board of Directors has determined that
directors shall be elected at such meeting, by any stockholder of the
Corporation who is a stockholder of record at the time of giving of notice of
the special meeting, who shall be entitled to vote at the meeting and who
complies with the notice procedures set forth in this Section 11. If the
Corporation calls a special meeting of stockholders for the purpose of electing
one or more directors to the Board of Directors, any such stockholder may
nominate a person or persons (as the case may be), for election to such
position(s) as specified in the Corporation's notice of meeting, if the
stockholder's notice required by paragraph (A)(2) of this Section 11 shall be
delivered to the Secretary at the principal executive offices of the Corporation
not earlier than the ninetieth (90th) day prior to such special meeting not

      C.  GENERAL.

          1. Only such persons who are nominated in accordance with the
procedures set forth in this Section 11 shall be eligible to serve as directors
and only such business shall be conducted at a meeting of stockholders as shall
have been brought before the meeting in accordance with the procedures set forth
in this Section 11. Except as otherwise provided by law, the Certificate of
Incorporation or these By-Laws, the chairman of the meeting shall have the power
and duty to determine whether a nomination or any business proposed to be
brought before the meeting was made or proposed, as the case may be, in
accordance with the procedures set forth in this Section 11 and, if any proposed
nomination or business is not incompliance herewith, to declare that such
defective proposal or nomination shall be disregarded.

          2. For purposes of this Section 11, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or comparable national news service or in a document publicly filed by the
Corporation with the Securities and Exchange Commission pursuant to Section 13,
14 and 15(d) of the Exchange Act.

          3. Notwithstanding the foregoing provisions of this Section 11, a
stockholder shall also comply with all applicable requirements of the Exchange
Act and the rules and regulations thereunder with respect to the matters set
forth herein. Nothing in this Section 11 shall be deemed to affect any rights
(i) of stockholders to request inclusion of proposals in the Corporation's proxy
statement pursuant to Rule 14a-8 under the Exchange Act or (ii) of the holders
of any series of Preferred Stock to elect directors under specified
circumstances.

      Notwithstanding any other provision of law, the Certificate of
Incorporation or these By-Laws, and notwithstanding the fact that a lesser
percentage may be specified by law, the affirmative vote of the holders of at
least 66.67% of the votes which all the stockholders would be entitled to cast
at any annual election of directors or class of directors shall be required to
amend or repeal, or to adopt any provision inconsistent with, this Section 11.

                                    DIRECTORS

      Section 1. The number of directors which shall constitute the whole Board
shall be determined by resolution of the Board of Directors or by the

election at which directors are to be elected and until their successors are
duly elected and shall qualify, unless sooner displaced. If there are no
directors in office, then an election of directors may be held in the manner
provided by statute. If, at the time of filling any vacancy or any newly created
directorship, the directors then in office shall constitute less than a majority
of the whole Board (as constituted immediately prior to any such increase), the
Court of Chancery may, upon application of any stockholder or stockholders
holding at least ten percent (10%) of the total number of the shares at the time
outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office.

      Section 3. The business of the Corporation shall be managed by or under
the direction of its Board of Directors which may exercise all such powers of
the Corporation and do all such lawful acts and things as are not by statute or

or these By-Laws, members of the Board of Directors, or any committee designated
by the Board of Directors, may participate in a meeting of the Board of
Directors, or any committee, by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

                             Committees of Directors

      Section 10. The Board of Directors may, by resolution passed by a majority
of the whole Board, designate one or more committees, each committee to consist

absent or disqualified member at any meeting of the committee.

      In the absence of disqualification of a member of a committee, the member
or members thereof present at any meeting and not disqualified from voting,
whether or not such member or members constitute a quorum, may unanimously
appoint another member of the Board of Directors to act at the meeting in the
place of any such absent or disqualified member.

      Section 11. Each committee shall keep regular minutes of its meetings and
report the same to the Board of Directors when required.

Incorporation or these By-Laws, the Board of Directors shall have the authority
to fix the compensation of directors. The directors may be paid their expenses,
if any, of attendance at each meeting of the Board of Director and may be paid a
fixed sum for attendance at each meeting of the Board of Directors or a stated
salary as director. No such payment shall preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor. Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

<PAGE>

                                  ARTICLE VIII

                                    DIVIDENDS

      Section 1. Dividends upon the capital stock of the Corporation, subject to

the Board of Directors at any regular or special meeting, pursuant to law.
Dividends may be paid in cash, in property, or in shares of the capital stock,
subject to the provisions of the Certificate of Incorporation.

      Section 2. Before payment of any dividend, there may be set aside out of
any funds of the Corporation available for dividends such sum or sums as the
directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the Corporation, or for such other
purposes as the directors shall think conducive to the interest of the
Corporation, and the directors may modify or abolish any such reserve in the

the Board of Directors may from time to time designate.

                                   Fiscal Year

      Section 4. The fiscal year of the Corporation shall end on December 31,

                                      Seal

      Section 5. The Board of Directors may adopt a corporate seal having

facsimile thereof to be impressed or affixed or reproduced or otherwise.

                                 Indemnification

      Section 6. The Corporation shall, to the fullest extent authorized under
the laws of the State of Delaware, as those laws may be amended and supplemented
from time to time, indemnify any director or officer made, or threatened to be
made, a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of being a director or officer of the
Corporation or a predecessor corporation or, at the Corporation's request, a


                                       12

<PAGE>

director or officer of another corporation, provided, however, that the
Corporation shall indemnify any such agent in connection with a proceeding
initiated by such agent only if such proceeding was authorized by the Board of
Directors of the Corporation. The indemnification provided for in this Section 6
shall: (i) not be deemed exclusive of any other rights to which those
indemnified may be entitled under any bylaw, agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in their official
capacities and as to action in another capacity while holding such office, (ii)
continue as to a person who has ceased to be a director, and (iii) inure to the
benefit of the heirs, executors and administrators of such a person. The
Corporation's obligation to provide indemnification under this Section 6 shall
be offset to the extent of any other source of indemnification or any otherwise
applicable insurance coverage under a policy maintained by the Corporation or
any other person.

      Expenses incurred by a director or officer of the Corporation in defending
a civil or criminal action, suit or proceeding by reason of the fact that such
individual is or was a director of the Corporation (or was serving at the
Corporation's request as a director or officer of another corporation) shall be
paid by the Corporation in advance of the final disposition of such action, suit
or proceeding upon receipt of an undertaking by or on behalf of such director to
repay such amount if it shall ultimately be determined that such individual is
not entitled to be indemnified by the Corporation as authorized by relevant
sections of the General Corporation Law of Delaware. Notwithstanding the
foregoing, the Corporation shall not be required to advance such expenses to an
agent who is a party to an action, suit or proceeding brought by the Corporation
and approved by a majority of the Board of Directors of the Corporation which
alleges willful misappropriation of corporate assets by such agent, disclosure
of confidential information in violation of such agent's fiduciary or
contractual obligations to the Corporation or any other willful and deliberate
breach in bad faith of such agent's duty to the Corporation or its stockholders.

      The foregoing provisions of this Section 6 shall be deemed to be a
contract between the Corporation and each director who serves in such capacity
at any time while this bylaw is in effect, and any repeal or modification
thereof shall not affect any rights or obligations then existing with respect to
any state of facts then or theretofore existing or any action, suit or
proceeding theretofore or thereafter brought based in whole or in part upon any
such state of facts.

      To assure indemnification under this Section 6 of all directors and
officers who are determined by the Corporation or otherwise to be or to have
been "fiduciaries" of any employee benefit plan of the Corporation which may
exist from time to time, Section 145 of the General Corporation Law of Delaware
shall, for the purposes of this Section 6, be interpreted as follows: and "other
enterprise" shall be deemed to include such an employee benefit plan, including
without limitation, any plan of the Corporation which is governed by the Act of
Congress entitled "Employee Retirement Income Security Act of 1974," as amended
from time to time; the Corporation shall be deemed to have requested a person to
serve an employee benefit plan where the performance by such person of his
duties to the Corporation also imposes duties on, or otherwise involves services
by, such person to the plan or participants or beneficiaries of the plan; excise
taxes assessed on a person with respect to an employee benefit plan pursuant to
such Act of Congress shall be deemed "fines."

                      Transactions with Interested Parties

      Section 7. No contract or transaction between the Corporation and one or
more of the directors or officers, or between the Corporation and any other
corporation, partnership, association, or other organization in which one or

MiningCo.com, Inc.
220 East 42nd Street, 24th Floor
New York, NY  10017

Ladies and Gentlemen:

      We have assisted in the preparation and filing by MiningCo.com, Inc. (the
"Company") of a Registration Statement on Form S-1, as amended through March 17,
1999 (the "Registration Statement"), with the Securities and Exchange
Commission, relating to the sale of up to 3,450,000 shares (the "Shares") of
Common Stock, $.001 par value (the "Common Stock"), of the Company. A form of
underwriting agreement (the "Underwriting Agreement") is filed as an exhibit to
the Registration Statement.

      We have examined such records and documents and have made such examination
of laws as we considered necessary to form a basis for the opinion set forth
herein. In our examination, we have assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals, and the
conformity with the originals of all documents submitted to us as copies
thereof.

      Based upon and subject to the foregoing, we are of the opinion that the
Shares have been duly authorized and, when sold and paid for in accordance with
the terms of the Underwriting Agreement, will be validly issued, fully paid and
nonassessable.

      We hereby consent to the use of our name in the Registration Statement
under the caption "Legal Matters" in the related Prospectus and consent to the
filing of this opinion as an exhibit thereto.

                                          Very truly yours,


                                          /s/ Brobeck, Phleger & Harrison LLP

                GLOBALCENTER Master Service Agreement No. ____

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

            This Master Services Agreement (this "Agreement") is entered into as
the 27th day of January, 1998 ("Effective Date") by and between the entity
indicated on the Services Order form attached hereto, with an office at the
address listed on the Services Order Form, ("Client"), and GlobalCenter Inc., a
corporation with offices at 88 Pine Street, New York, New York ("GlobalCenter")
and describes the terms and conditions pursuant to which GlobalCenter shall
license to Client certain Software and provide certain Services (as defined
below).

            In consideration of the mutual promises and upon the terms and
conditions set forth below, the parties agree as follows

1. NATURE OF AGREEMENT This is an Agreement for the provision by GlobalCenter of
Internet connectivity services (the "Bandwidth"), the lease of equipment to
provide such services (the "Hardware"), the availability of space to store and
operate such Hardware ("Space") and the licensing of software to provide such
Services (the "Software"), together comprising an Internet connectivity and
collocation package to be provided by GlobalCenter under this Agreement
(together, the "Services").

2. SERVICE ORDERS

2.1. Orders. Client may issue one or more service orders describing the
Bandwidth, Space, Hardware, and Software that Client desires ("Service Order").
Each Service Order Exhibit I will set forth the prices, initial term of Services
and other information in the form set forth in the Service Order Form. No
Service Order shall be effective until accepted by GlobalCenter. All Service
Orders will be subject to the terms and conditions of this Agreement, and the
terms of this Agreement shall supersede any terms and conditions which may
appear on Client's order form, or purchase order unless GlobalCenter signs such
order and thereby agrees to such amendment, in which event such amendment shall
supersede this agreement.

2.2. Cancellation. In the event that Client cancels or terminates a Service
Order at any time for any reason whatsoever other than expiration of a Service
Order, a Service Interruption (as defined below), or after the first sixty (60)
days of the agreement, Client agrees to pay GlobalCenter a cancellation fee
equaling two (2) months of the Monthly Recurring Charges specified in the
Service Order which shall become due and owing as of the effective date of
cancellation or termination.

2.3. IP Addresses. GlobalCenter may assign on a temporary basis a reasonable
number of Internet Protocol Addresses ("IP Addresses") from the address space
assigned to the GlobalCenter by InterNIC. Client acknowledges that the IP
Addresses are the sole property of GlobalCenter are assigned to Client as part
of the Service, and are not "portable," as such term is used by InterNIC.
GlobalCenter reserves the right to change the IP Address assignments at any
time; however, GlobalCenter shall use reasonable efforts to avoid any disruption
to Client resulting from such renumbering requirement. GlobalCenter will give
Client reasonable notice of any such renumbering. Client agrees that it will
have no right to IP Addresses upon termination of this Agreement, and that any
renumbering required of Client after termination shall be the sole
responsibility of Client.


                                                                               1

falsifying one's network identity for improper or illegal purposes, sending
unsolicited mass e-mailings, propagation of computer worms and viruses, and
using the network to make unauthorized entry to any other machine accessible via
the network. If GlobalCenter has reasonable grounds to believe that Client or a
User is utilizing the Services for any such illegal or disruptive purpose,

such problem and an opportunity to cure. Client shall defend, indemnify, hold

GlobalCenter Value-Added Services                                     EXHIBIT #2
- --------------------------------------------------------------------------------

Items 1. to VII. are included in the costs outlined in the GlobalCenter
proposal:

I.    The NY GlobalCenter Network Operations Center will provide constant
      monitoring of server output 24 hours a day, 7 days a week, 365 days a
      year.

      ICMP, HTTP, and process monitoring will be performed by GlobalCenter via
      SNMP and NT Performance counter querying. In addition, specific URLs will
      be checked through the standard HTTP query process..

II.   ICMP checks will be performed every minute and http checks every 5 minutes
      by the NOC. URL checking will take place at 10-15 minute intervals
      (dependent upon the number of URL s that are to be checked). This interval
      can be modified at any time to meet changing MiningCo requirements.

III.  The GlobalCenter NOC will monitor the following conditions and will take
      appropriate action (to be agreed between MiningCo and GlobalCenter - see
      below) when the stated conditions are met:

      1)    ICMP tests fail for more than 5 minutes
      2)    HTTP checks fail for more than 5 minutes
      3)    If server CPU usage stays above 70% for 5 minutes or longer.
      4)    If server available memory remains below 10 Megabytes for 5 minutes
            or longer.
      5)    If server hard drive space falls below 1 gigabyte.

      In addition, GlobalCenter can monitor specific server processes as
      MiningCo require. With these processes we can monitor:

      6)    If the process is running on the server.
      7)    If the process exceeds a certain threshold of virtual bytes used.
      8)    If any process thread count increases above a certain threshold.

IV.   First level NOC staff, in the event of a fault condition, will attempt to
      solve the problem immediately. This excludes any specific events requiring
      immediate notification of MiningCo - this can be done automatically from
      our monitoring systems via e-mail or pager; alternatively, NOC personnel
      can call a nominated MiningCo contact. After 15 minutes, the outage will
      be escalated to the appropriate level 2 technician, and if not resolved in
      another 15 minutes time (30 minutes total), MiningCo will be notified and
      a decision will be made on a further course of action.

V.    At all times, NOC personnel will use mutually agreed upon procedures to
      move toward resolution of the problem GlobalCenter will perform tape
      rotation on a regular basis as required. System restores can be carried
      out by GlobalCenter NOC or TAM as instructed by MiningCo personnel, to
      mutually agreed upon procedures.

VI.   GlobalCenter will provide a web-interface to MiningCo which will deliver a
      real-time view of Bandwidth usage, GlobalCenter DS3 useage and a current
      status of all servers at GC facilities.

<PAGE>

VII.  GlobalCenter will provide a dedicated Primary Technical Account Manager
      for support, failure resolution, and scope of work performance who will
      be:

      - Educated in MiningCo's operations and configuration
      - Directly reachable during normal business hours (8AM to 5PM EST) via
        phone or pager.
      - Familiar with scope of work and contractual issues.

VII.  (a)   GlobalCenter will provision a T-1 circuit from The Mining Company's
            office located at 220 East 42nd street to GlobalCenter's data center
            located at 60 Hudson Street.

      (b)   GlobalCenter will provision a T-1 circuit from The Mining Company's
            office located at 20 Harlem Avenue in White Plains N.Y. to
            GlobalCenter's data center located at 60 Hudson Street.

      (c)   The cost of migration of servers from The Mining Company's office to
            GlobalCenter's data center is covered by the start up costs which
            are covered in the "Installation" portion of Exhibit #1, Title:
            Globalcenter Service order.

      (d)   Configuration of Mining Company's servers will be done by employees
            of The Mining Company for the initial installation into
            GlobalCenter's data center, and assisted by GlobalCenter TAMS if
            necessary. For all servers moved to GlobalCenter at future dates, a
            standard configuration will be established between the GlobalCenter
            TAM, Sara, and Olga of the Mining Company.

      (e)   Rebooting of Servers will be established based on either human or
            automatic reboot procedures to be established at the Migration
            meeting, prior to moving equipment to 60 Hudson.

      (f)   Servers to be installed at the GlobalCenter Data center are: Index
            server(s), Mail server(s), Net Gravity server(s), boards machine(s).
            All machines migrated to the GlobalCenter Data center will be
            cataloged by The Mining Company and GlobalCenter by serial number,
            Brand name, and number of each type of server being moved.

      (g)   GlobalCenter will be responsible for secondary DNS for The Mining
            Company.

      (h)   Back-up currently run every evening by The Mining Company.
            GlobalCenter will run back-up on times agreed by The Mining Company
            and the GlobalCenter TAM.

      (i)   All specifics that were not covered in the above areas (a-h) will be
            covered at length during the Migration Meeting. A thorough plan will
            be in place before a single server is moved from The Mining
            Company's office. A migration meeting will be set for a time that is
            reasonable for both parties to discuss in depth all aspects of the
            migration.

<PAGE>

      Items covered under Section Vlll. would be provided as additional services
      with an associated additional cost, usually billed in number of TAM hours
      used.

VIII. GlobalCenter has the capability to provide value added services, such as;

      - a content monitoring system
      - server load-balancing
      - server mirroring (Express Mirror is a Unix based product) 
      - mail system upgrades
      - database replication consultancy etc.

      These services are available upon request and execution of a service order
      by MiningCo. This service will involve an extra cost to MiningCo.

95th Percentile Rule

Every GlobalCenter customer purchases a certain amount of guaranteed bandwidth
on GC/ISl's Internet Backbone per month for an entire year. We realize that
there are certain instances that your Web Site will burst over your purchased
amount of bandwidth. Therefore, we have devised a billing method to accommodate
for bandwidth burst over your subscribed amount using the "95th Percentile
Rule."

First of all, you will be billed monthly for the bandwidth you have committed to
each month. GlobalCenter's SNMP bandwidth monitoring will sample (take a data
point reflecting how much bandwidth you are utilizing at that particular
instance) your Internet connection every 5 minutes and store those samples for a
period of one month.

At the end of the month, all the data samples ABOVE the amount of bandwidth you
have committed to will be collected and then be sorted from highest to lowest
and the top 5% will be discarded. The remaining data sample will then be
referred to as the "95th Percentile" number. This number will then be used as
the basis in computing the additional bandwidth rate for that particular month
over what bandwidth you have already purchased.

Service Order subject to a GlobalCenter Master Service Agreement. Service Order
serves as a Purchase Order when signed by an authorized representative. Please
send or FAX signed Service Order to the above address.

provide such services (the "Hardware"), the availability of space to store and
operate such Hardware ("Space") and the licensing of software to provide such
Services (the "Software"), together comprising an Internet connectivity and
collocation package to be provided by GlobalCenter under this Agreement
(together, the "Services").

Service Order shall be effective until accepted by GlobalCenter. All Service
Orders will be subject to the terms and conditions of this Agreement, and the
terms of this Agreement shall supersede any terms and conditions which may
appear on Client's order form, or purchase order unless GlobalCenter signs such
order and thereby agrees to such amendment, in which event such amendment shall
supersede this agreement.

2.2. Cancellation. In the event that Client cancels or terminates a Service
Order at any time for any reason whatsoever other than expiration of a Service
Order, a Service Interruption (as defined below), or after the first sixty (60)
days of the agreement, Client agrees to pay GlobalCenter a cancellation fee
equaling two (2) months of the Monthly Recurring Charges specified in the
Service Order which shall become due and owing as of the effective date of
cancellation or termination.

of the Service, and are not "portable," as such term is used by InterNIC.
GlobalCenter reserves the right to change the IP Address assignments at any
time; however, GlobalCenter shall use reasonable efforts to avoid any disruption
to Client resulting from such renumbering requirement. GlobalCenter will give
Client reasonable notice of any such renumbering. Client agrees that it will
have no right to IP Addresses upon termination of this Agreement, and that any
renumbering required of Client after termination shall be the sole
responsibility of Client.

6. SERVICE INTERRUPTIONS

6.1. 99% Uptime Guarantee. In the event of Downtime (as defined below), the
monthly fee payable for the Services shall be reduced as follows:

        6.1.1. if the total Downtime in the calendar month is more than two (2)
        hours, but does not exceed four (4) hours, the monthly fee for that
        month shall be reduced by one-third (33.3%);

        6.1.2. if the total Downtime in the calendar month is more than four (4)
        hours, but does not exceed eight (8) hours, the monthly fee for that
        month shall be reduced by two-thirds (66.6%);

        If the total Downtime in the calendar month is more than eight (8)
        hours, the monthly fee for that month shall be waived.

For the purposes of this Section, Downtime shall mean any interruption of one
(1) minute or more in the availability to users of any Web site residing on the
Hardware and made available through the Services, only if such interruption is
due to either (i) failure by GlobalCenter to manage a server anomaly as agreed
in Exhibit II so as to avoid interruption in Web availability, or (ii) a
disruption in the connection between any such server and the Internet. For
purposes of this Section. the Internet is deemed to consist of services that
commence where GlobalCenter transmits a Client's content to GlobalCenter's
carrier(s) at the GlobalCenter border router port(s). Such carriers provide
GlobalCenter with private and dedicated bandwidth. GlobalCenter undertakes no
obligation for the circuit or link between GlobalCenter's facilities and such
carrier's services. If router packet loss is excess of seventy percent (70%) and
is sustained for sixty (60) seconds or more, GlobalCenter will classify this an
"outage." If an "outage" continues for a time period of more than two (2)
minutes, then such outage will be deemed Downtime.

6.2. Investigation of Service Interruptions. GlobalCenter will investigate any
report of Downtime, and attempt to remedy any Downtime expeditiously.
GlobalCenter reasonably 


                                                                               4
<PAGE>

                GLOBALCENTER Master Service Agreement No. ____

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

determines that all facilities, systems and equipment furnished by GlobalCenter
are functioning properly, and that Downtime arose from some other cause.
GlobalCenter reserves the right to recover labor and materials cost for services
actually performed at the usual and customary rates for similar services
provided by GlobalCenter to clients in the same locality.

6.3. Termination. Client may terminate a Service Order in the event of Downtime
of either twenty-four (24) hours of cumulative time during any continuous twelve
(12) month period, or any continuous Downtime of eight (8) hours or more.

6.4. Sole Remedy. The terms and conditions of this Section 6 shall Client's sole
remedy and GlobalCenter's sole obligation for any Downtime.

7. USER CONTENT GlobalCenter acknowledges that GlobalCenter shall have no right,
title or interest in or to any of the services, any postings, data or
transmission using the services (the "Content"). Disruptions include without
limitation distribution of unsolicited advertising or chain letters, repeated
harassment of other network users, wrongly impersonating another such user,
falsifying one's network identity for improper or illegal purposes, sending
unsolicited mass e-mailings, propagation of computer worms and viruses, and
using the network to make unauthorized entry to any other machine accessible via
the network. If GlobalCenter has reasonable grounds to believe that Client or a
User is utilizing the Services for any such illegal or disruptive purpose,
GlobalCenter may suspend or terminate Services immediately upon notice to Client
provided that GlobalCenter shall attempt to give client reasonable notice of
such problem and an opportunity to cure. Client shall defend, indemnify, hold
harmless GlobalCenter from and against all liabilities and costs (including
reasonable attorney's fees) arising from any and all claims by any person
arising out of Client's use of the Services, including without limitation any
content.

95th Percentile Rule

Every GlobalCenter client purchases a certain amount of guaranteed bandwidth on
GC/ISl's Internet Backbone per month for an entire year. We realize that there
are certain instances that your Web Site will burst over your purchased amount
of bandwidth. Therefore, we have devised a billing method to accommodate for
bandwidth burst over your subscribed amount using the "95th Percentile Rule."

First of all, you will be billed monthly for the bandwidth you have committed to
each month. GlobalCenter's SNMP bandwidth monitoring will sample (take a data
point reflecting how much bandwidth you are utilizing at that particular
instance) your Internet connection every 5 minutes and store those samples for a
period of one month.

At the end of the month, all the data samples ABOVE the amount of bandwidth you
have committed to will be collected and then be sorted from highest to lowest
and the top 5% will be discarded. The remaining data sample will then be
referred to as the "95th Percentile" number. This number will then be used as
the basis in computing the additional bandwidth rate for that particular month
over what bandwidth you have already purchased.

Service Order subject to a GlobalCenter Master Service Agreement. Service Order
serves as a Purchase Order when signed by an authorized representative. Please

                               MININGCO.COM, INC.
                        1999 EMPLOYEE STOCK PURCHASE PLAN


         I.       PURPOSE OF THE PLAN

                  This 1999 Employee Stock Purchase Plan is intended to promote
the interests of MiningCo.com, Inc., a Delaware corporation, by providing
eligible employees with the opportunity to acquire a proprietary interest in the
Corporation through participation in a payroll-deduction based employee stock
purchase plan designed to qualify under Section 423 of the Code.

                  Capitalized terms herein shall have the meanings assigned to
such terms in the attached Appendix.

         II.      ADMINISTRATION OF THE PLAN

                  The Plan Administrator shall have full authority to interpret
and construe any provision of the Plan and to adopt such rules and regulations
for administering the Plan as it may deem necessary in order to comply with the
requirements of Section 423 of the Code. Decisions of the Plan Administrator
shall be final and binding on all parties having an interest in the Plan.

         III.     STOCK SUBJECT TO PLAN

                  A. The stock purchasable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares of Common
Stock purchased on the open market. The maximum number of shares of Common Stock
which may be issued over the term of the Plan shall not exceed One Hundred
Twenty-Five Thousand (125,000) shares.

                  B. Should any change be made to the Common Stock by reason of
any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a
class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and class of securities
issuable under the Plan, (ii) the maximum number and class of securities
purchasable per Participant on any one Purchase Date and (iii) the number and
class of securities and the price per share in effect under each outstanding
purchase right in order to prevent the dilution or enlargement of benefits
thereunder.

         IV.      OFFERING PERIODS

                  A. Shares of Common Stock shall be offered for purchase under
the Plan through a series of successive offering periods until such time as (i)
the maximum number of shares of Common Stock available for issuance under the
Plan shall have been purchased or (ii) the Plan shall have been sooner
terminated.

                  B. Each offering period shall be of such duration (not to
exceed twenty-four (24) months) as determined by the Plan Administrator prior to
the start date of such offering period. However, the initial offering period
shall commence at the Effective Time and terminate 


<PAGE>

on the last business day in April 2001. Subsequent offering periods shall
commence as designated by the Plan Administrator.

                  C. Each offering period shall be comprised of a series of one
or more successive Purchase Intervals. Purchase Intervals shall run from the
first business day in May each year to the last business day in October of the
same year and from the first business day in November each year to the last
business day in April of the following year. However, the first Purchase
Interval in effect under the initial offering period shall commence at the
Effective Time and terminate on the last business day in October 1999.

                  D. Should the Fair Market Value per share of Common Stock on
any Purchase Date within an offering period be less than the Fair Market Value
per share of Common Stock on the start date of that offering period, then that
offering period shall automatically terminate immediately after the purchase of
shares of Common Stock on such Purchase Date, and a new offering period shall
commence on the next business day following such Purchase Date. The new offering
period shall have a duration of twenty (24) months, unless a shorter duration is
established by the Plan Administrator within five (5) business days following
the start date of that offering period.

                  E. Notwithstanding anything to the contrary herein, should the
total number of shares of Common Stock to be purchased on any particular date
exceed the number of shares then available for issuance under the Plan, then the
Plan Administrator shall have the right to terminate the offering period during
which such purchase occurs and to determine when a new offering period shall
commence.

         V.       ELIGIBILITY

                  A. Each individual who is an Eligible Employee on the start
date of the initial offering period under the Plan may enter that offering
period on such start date or on any subsequent Semi-Annual Entry Date within
that offering period, provided he or she remains an Eligible Employee.

                  B. Each individual who is an Eligible Employee on the start
date of any subsequent offering period under the Plan may enter that offering
period on such start date or on any subsequent Semi-Annual Entry Date within
that offering period, provided in each case that he or she has completed at
least thirty (30) days of continuous employment with the Corporation or a
Corporate Affiliate prior to such date.

                  C. Each individual who first becomes an Eligible Employee
after the start date of an offering period may enter that offering period on any
subsequent Semi-Annual Entry Date within that offering period on which he or she
is an Eligible Employee, provided he or she has completed at least thirty (30)
days of continuous employment with the Corporation or a Corporate Affiliate
prior to such Semi-Annual Entry Date.

                  D. The date an individual enters an offering period shall be
designated his or her Entry Date for purposes of that offering period.


                                       2

<PAGE>

                  E. To participate in the Plan for a particular offering
period, the Eligible Employee must complete the enrollment forms prescribed by
the Plan Administrator (including a stock purchase agreement and a payroll
deduction authorization) and file such forms with the Plan Administrator (or its
designate) on or before his or her scheduled Entry Date.

         VI.      PAYROLL DEDUCTIONS

                  A. The payroll deduction authorized by the Participant for
purposes of acquiring shares of Common Stock during an offering period may be
any multiple of one percent (1%) of the Cash Earnings paid to the Participant
during each Purchase Interval within that offering period, up to a maximum of
fifteen percent (15%). The deduction rate so authorized shall continue in effect
throughout the offering period, except to the extent such rate is changed in
accordance with the following guidelines:

                         (i)    The Participant may, at any time during the 
         offering period, reduce his or her rate of payroll deduction to
         become effective as soon as possible after filing the appropriate
         form with the Plan Administrator. The Participant may not, however,
         effect more than one (1) such reduction per Purchase Interval.

                         (ii)   The Participant may, prior to the commencement 
         of any new Purchase Interval within the offering period, increase
         the rate of his or her payroll deduction by filing the appropriate
         form with the Plan Administrator. The new rate (which may not exceed
         the fifteen percent (15%) maximum) shall become effective on the
         start date of the first Purchase Interval following the filing of
         such form.

                  B. Payroll deductions shall begin on the first pay day
following the Participant's Entry Date into the offering period and shall
(unless sooner terminated by the Participant) continue through the pay day
ending with or immediately prior to the last day of that offering period. The
amounts so collected shall be credited to the Participant's book account under
the Plan, but no interest shall be paid on the balance from time to time
outstanding in such account. The amounts collected from the Participant shall
not be required to be held in any segregated account or trust fund and may be
commingled with the general assets of the Corporation and used for general
corporate purposes.

                  C. Payroll deductions shall automatically cease upon the
termination of the Participant's purchase right in accordance with the
provisions of the Plan.

                  D. The Participant's acquisition of Common Stock under the
Plan on any Purchase Date shall neither limit nor require the Participant's
acquisition of Common Stock on any subsequent Purchase Date, whether within the
same or a different offering period.

         VII.     PURCHASE RIGHTS

                  A. GRANT OF PURCHASE RIGHT. A Participant shall be granted a
separate purchase right for each offering period in which he or she
participates. The purchase right shall be granted on the Participant's Entry
Date into the offering period and shall provide the 


                                       3

<PAGE>

Participant with the right to purchase shares of Common Stock, in a series of
successive installments over the remainder of such offering period, upon the
terms set forth below. The Participant shall execute a stock purchase agreement
embodying such terms and such other provisions (not inconsistent with the Plan)
as the Plan Administrator may deem advisable.

                  Under no circumstances shall purchase rights be granted under
the Plan to any Eligible Employee if such individual would, immediately after
the grant, own (within the meaning of Code Section 424(d)) or hold outstanding
options or other rights to purchase, stock possessing five percent (5%) or more
of the total combined voting power or value of all classes of stock of the
Corporation or any Corporate Affiliate.

                  B. EXERCISE OF THE PURCHASE RIGHT. Each purchase right shall
be automatically exercised in installments on each successive Purchase Date
within the offering period, and shares of Common Stock shall accordingly be
purchased on behalf of each Participant (other than Participants whose payroll
deductions have previously been refunded pursuant to the Termination of Purchase
Right provisions below) on each such Purchase Date. The purchase shall be
effected by applying the Participant's payroll deductions for the Purchase
Interval ending on such Purchase Date to the purchase of whole shares of Common
Stock at the purchase price in effect for the Participant for that Purchase
Date.

                  C. PURCHASE PRICE. The purchase price per share at which
Common Stock will be purchased on the Participant's behalf on each Purchase Date
within the offering period shall be equal to eighty-five percent (85%) of the
LOWER of (i) the Fair Market Value per share of Common Stock on the
Participant's Entry Date into that offering period or (ii) the Fair Market Value
per share of Common Stock on that Purchase Date.

                  D. NUMBER OF PURCHASABLE SHARES. The number of shares of
Common Stock purchasable by a Participant on each Purchase Date during the
offering period shall be the number of whole shares obtained by dividing the
amount collected from the Participant through payroll deductions during the
Purchase Interval ending with that Purchase Date by the purchase price in effect
for the Participant for that Purchase Date. However, the maximum number of
shares of Common Stock purchasable per Participant on any one Purchase Date
shall not exceed Five Hundred (500) shares, subject to periodic adjustments in
the event of certain changes in the Corporation's capitalization.

                  E. EXCESS PAYROLL DEDUCTIONS. Any payroll deductions not
applied to the purchase of shares of Common Stock on any Purchase Date because
they are not sufficient to purchase a whole share of Common Stock shall be held
for the purchase of Common Stock on the next Purchase Date. However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable on the Purchase Date
shall be promptly refunded.

                  F. TERMINATION OF PURCHASE RIGHT. The following provisions
shall govern the termination of outstanding purchase rights:

                         (i)    A  Participant may, at any time prior to the 
         next scheduled Purchase Date in the offering period, terminate his
         or her outstanding 


                                       4

<PAGE>

         purchase right by filing the appropriate form with the Plan
         Administrator (or its designate), and no further payroll deductions
         shall be collected from the Participant with respect to the
         terminated purchase right. Any payroll deductions collected during
         the Purchase Interval in which such termination occurs shall, at the
         Participant's election, be immediately refunded or held for the
         purchase of shares on the next Purchase Date. If no such election is
         made at the time such purchase right is terminated, then the payroll
         deductions collected with respect to the terminated right shall be
         refunded as soon as possible.

                         (ii)   The termination of such purchase right shall be 
         irrevocable, and the Participant may not subsequently rejoin the
         offering period for which the terminated purchase right was granted.
         In order to resume participation in any subsequent offering period,
         such individual must re-enroll in the Plan (by making a timely
         filing of the prescribed enrollment forms) on or before his or her
         scheduled Entry Date into that offering period.

                         (iii)  Should the Participant cease to remain an
         Eligible Employee for any reason (including death, disability or
         change in status) while his or her purchase right remains
         outstanding, then that purchase right shall immediately terminate,
         and all of the Participant's payroll deductions for the Purchase
         Interval in which the purchase right so terminates shall be
         immediately refunded. However, should the Participant cease to
         remain in active service by reason of an approved unpaid leave of
         absence, then the Participant shall have the right, exercisable up
         until the last business day of the Purchase Interval in which such
         leave commences, to (a) withdraw all the payroll deductions
         collected to date on his or her behalf for that Purchase Interval or
         (b) have such funds held for the purchase of shares on his or her
         behalf on the next scheduled Purchase Date. In no event, however,
         shall any further payroll deductions be collected on the
         Participant's behalf during such leave. Upon the Participant's
         return to active service (i) within ninety (90) days following the
         commencement of such leave or, (ii) prior to the expiration of any
         longer period for which such Participant's right to reemployment
         with the Corporation is guaranteed by either statute or contract,
         his or her payroll deductions under the Plan shall automatically
         resume at the rate in effect at the time the leave began. However,
         should the Participant's leave of absence exceed ninety (90) days
         and his or her re-employment rights not be guaranteed by either
         statute or contract, then the Participant's status as an Eligible
         Employee will be deemed to terminate on the ninety-first (91st) day
         of that leave, and such Participant's purchase right for the
         offering period in which that leave began shall thereupon terminate.
         An individual who returns to active employment following such a
         leave shall be treated as a new Employee for purposes of the Plan
         and must, in order to resume participation in the Plan, re-enroll in
         the Plan (by making a timely filing of the prescribed enrollment
         forms) on or before his or her scheduled Entry Date into the
         offering period.

                  G. CORPORATE TRANSACTION. Each outstanding purchase right
shall automatically be exercised, immediately prior to the effective date of any
Corporate Transaction, by applying the payroll deductions of each Participant
for the Purchase Interval in which such 


                                       5

<PAGE>

Corporate Transaction occurs to the purchase of whole shares of Common Stock at
a purchase price per share equal to eighty-five percent (85%) of the LOWER of
(i) the Fair Market Value per share of Common Stock on the Participant's Entry
Date into the offering period in which such Corporate Transaction occurs or (ii)
the Fair Market Value per share of Common Stock immediately prior to the
effective date of such Corporate Transaction. However, the applicable
limitations on the number of shares of Common Stock purchasable per Participant
and in the aggregate shall continue to apply to any such purchase.

                  The Corporation shall use its best efforts to provide at least
ten (10)-days prior written notice of the occurrence of any Corporate
Transaction, and Participants shall, following the receipt of such notice, have
the right to terminate their outstanding purchase rights prior to the effective
date of the Corporate Transaction.

                  H. PRORATION OF PURCHASE RIGHTS. Should the total number of
shares of Common Stock to be purchased pursuant to outstanding purchase rights
on any particular date exceed the number of shares then available for issuance
under the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

                  I. ASSIGNABILITY. The purchase right shall be exercisable only
by the Participant and shall not be assignable or transferable by the
Participant.

                  J. STOCKHOLDER RIGHTS. A Participant shall have no stockholder
rights with respect to the shares subject to his or her outstanding purchase
right until the shares are purchased on the Participant's behalf in accordance
with the provisions of the Plan and the Participant has become a holder of
record of the purchased shares.

         VIII.    ACCRUAL LIMITATIONS

                  A. No Participant shall be entitled to accrue rights to
acquire Common Stock pursuant to any purchase right outstanding under this Plan
if and to the extent such accrual, when aggregated with (i) rights to purchase
Common Stock accrued under any other purchase right granted under this Plan and
(ii) similar rights accrued under other employee stock purchase plans (within
the meaning of Code Section 423) of the Corporation or any Corporate Affiliate,
would otherwise permit such Participant to purchase more than Twenty-Five
Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value per share on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.

                  B. For purposes of applying such accrual limitations to the 
purchase rights granted under the Plan, the following provisions shall be in
effect:

                         (i)    The right to acquire Common Stock under each 
         outstanding purchase right shall accrue in a series of installments
         on each successive Purchase Date during the offering period on which
         such right remains outstanding.


                                       6

<PAGE>

                         (ii)   No right to acquire Common Stock under any
         outstanding purchase right shall accrue to the extent the
         Participant has already accrued in the same calendar year the right
         to acquire Common Stock under one (1) or more other purchase rights
         at a rate equal to Twenty-Five Thousand Dollars ($25,000) worth of
         Common Stock (determined on the basis of the Fair Market Value per
         share on the date or dates of grant) for each calendar year such
         rights were at any time outstanding.

                  C. If by reason of such accrual limitations, any purchase
right of a Participant does not accrue for a particular Purchase Interval, then
the payroll deductions which the Participant made during that Purchase Interval
with respect to such purchase right shall be promptly refunded.

                  D. In the event there is any conflict between the provisions
of this Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

         IX.      EFFECTIVE DATE AND TERM OF THE PLAN

                  A. The Plan was adopted by the Board on __________, 1999 and

statement filed with the Securities and Exchange Commission), all applicable
listing requirements of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock is listed for trading and all other
applicable requirements established by law or regulation. In the event such
stockholder approval is not obtained, or such compliance is not effected, within
twelve (12) months after the date on which the Plan is adopted by the Board, the
Plan shall terminate and have no further force or effect, and all sums collected
from Participants during the initial offering period hereunder shall be
refunded.

                  B. Unless sooner terminated by the Board, the Plan shall
terminate upon the EARLIEST of (i) the last business day in April 2009, (ii) the
date on which all shares available for issuance under the Plan shall have been
sold pursuant to purchase rights exercised under the Plan or (iii) the date on
which all purchase rights are exercised in connection with a Corporate
Transaction. No further purchase rights shall be granted or exercised, and no
further payroll deductions shall be collected, under the Plan following such
termination.

         X.       AMENDMENT/TERMINATION OF THE PLAN

                  A. The Board may alter, amend, suspend or terminate the Plan
at any time to become effective immediately following the close of any Purchase
Interval. However, the Plan may be amended or terminated immediately upon Board
action, if and to the extent necessary to assure that the Corporation will not
recognize, for financial reporting purposes, any compensation expense in
connection with the shares of Common Stock offered for purchase 


                                       7

<PAGE>

under the Plan, should the financial accounting rules applicable to the Plan at
the Effective Time be subsequently revised so as to require the recognition of
compensation expense in the absence of such amendment or termination.

                  B. In no event may the Board effect any of the following
amendments or revisions to the Plan without the approval of the Corporation's
stockholders: (i) increase the number of shares of Common Stock issuable under
the Plan or the maximum number of shares purchasable per Participant on any one
Purchase Date, except for permissible adjustments in the event of certain
changes in the Corporation's capitalization, (ii) alter the purchase price
formula so as to reduce the purchase price payable for the shares of Common
Stock purchasable under the Plan or (iii) modify eligibility requirements for
participation in the Plan.

         XI.      GENERAL PROVISIONS

                  A. Nothing in the Plan shall confer upon the Participant any
right to continue in the employ of the Corporation or any Corporate Affiliate
for any period of specific duration or interfere with or otherwise restrict in
any way the rights of the Corporation (or any Corporate Affiliate employing such
person) or of the Participant, which rights are hereby expressly reserved by
each, to terminate such person's employment at any time for any reason, with or
without cause.

                  B. All costs and expenses incurred in the administration of
the Plan shall be paid by the Corporation; however, each Plan Participant shall
bear all costs and expenses incurred by such individual in the sale or other
disposition of any shares purchased under the Plan.

                  C. The provisions of the Plan shall be governed by the laws of
the State of New York without regard to that State's conflict-of-laws rules.
