     The information below is only a summary of more detailed information
included in other sections of this prospectus. This summary may not contain all
the information that is important to you or that you should consider before
buying shares in the offering. The other information is important, so please
read this entire prospectus carefully. Information contained on our Web site is
not part of this prospectus.

                          JUPITER COMMUNICATIONS, INC.

OUR BUSINESS


     We are a leading provider of research on Internet commerce, as measured by
both revenue and number of clients. Senior executives at client companies
utilize our research to make informed business decisions in a complex and
rapidly changing Internet economy. Our research, which is focused solely on the
Internet economy, provides our clients with comprehensive views of industry
trends, forecasts and best practices. Our analysis, supported by proprietary
data, emphasizes specific, actionable findings.


     Our research services are provided primarily through our continuous
subscription product, Strategic Planning Services, which we call SPS. SPS is a
combination of proprietary written analysis, supporting data and access to our
analysts. We typically bill clients annually in advance and deliver the products
and services over the term of the contract. We generate our research through
seven focused teams of research analysts and associates. Our proprietary
research is informed and supported by a dedicated data research group. We
increasingly deliver our products via the Internet.


     We have a highly diversified client base, including companies in the
Internet, media, telecommunications, technology, financial services, retail,
travel, consumer products and professional services industries. We have
successfully increased the number of SPS clients and our total contract value,
which is the annualized value of all SPS contracts at a given point in time. As
of June 30, 1999, we had 654 SPS contracts, an increase from 421 on December 31,
1998 and 145 on December 31, 1997. Our total contract value has increased from
$2.5 million on December 31, 1997, to $11.7 million on December 31, 1998 and to
$22.1 million on June 30, 1999. In addition, approximately 73% of the SPS
contracts that expired during the 12 months prior to June 30, 1999 were renewed.


     We also produce a wide range of conferences which offer senior executives
the opportunity to hear first-hand the insights of our analysts and the leading
decision makers in the Internet and technology industries. Because over 75% of
the attendees are not SPS clients, these conferences provide a unique
opportunity to promote our SPS research to potential clients. These conferences
also allow us to increase the public profile of our analysts, generate favorable
press and otherwise promote the Jupiter brand.


     Our revenues have increased from $8.5 million in 1997 to $14.8 million in
1998, and from $5.9 million in the six months ended June 30, 1998 to $14.4
million in the six months ended June 30, 1999. We have a limited operating
history, however, and have incurred net losses since our formation. As of June
30, 1999, we had an accumulated deficit of $5.8 million.


MARKET OPPORTUNITY


     We believe that the growth of the Internet, and the growth of Internet
commerce in particular, will continue to expand rapidly for the foreseeable
future both in the United States and abroad. A recent report by University of
Texas' Center for Research in Electronic Commerce estimated that the Internet
economy generated approximately $300 billion in U.S. revenue and was responsible
for 1.2 million jobs as of 1998. A recent study by the Organization for Economic
Cooperation and Development predicted that worldwide Internet commerce may grow
to $1 trillion by 2005. In addition, billion dollar markets are emerging on the
Internet for many different industry sectors. Specifically, for the U.S. we
project that by 2003 the online travel industry will grow to approximately $17
billion, online advertising will grow to approximately $12


                                        3
<PAGE>   5

billion, overall consumer online shopping will grow to approximately $43 billion
and that total assets held in online brokerage accounts will grow to
approximately $3 trillion.

     The rapid growth of Internet commerce and the related increase in
innovative products, services and technologies have made it difficult for
companies to understand and evaluate the steps they should take to engage in and
expand their Internet commerce activities, promote their online businesses and
compete effectively. Thus, demand is growing for timely and credible research to
assist companies in identifying revenue models and success criteria, analyzing
consumer adoption trends, developing effective sales and marketing strategies,
assessing market trends and analyzing the competitive landscape. Demand for
research, analysis and advice is also expected to increase as the growth in
Internet commerce and consumer use of new technologies impacts more industries
and expands into other geographic areas.

OUR STRATEGY

     Our objective is to be the premier global research company focusing on
Internet commerce. Key elements of our business strategy include the following:


     - Providing innovative research on Internet commerce;


     - Increasing our client base in the United States and abroad;

     - Increasing the level of sales to existing clients;

     - Pursuing international opportunities;

     - Continuing to strengthen the Jupiter brand;

     - Increasing the number of conferences that we produce; and

     - Enhancing our Web delivery platform.

(1) Pro forma basic and diluted net loss per common share is computed by
    dividing net loss by the pro forma weighted average number of shares of
    common stock. Pro forma weighted average number of shares of common stock
    gives effect to our reorganization from an LLC to a corporation as though
    the reorganization had occurred as of the beginning of each period
    indicated. Pro forma weighted average shares do not include any common stock
    equivalents because inclusion of common stock equivalents would have been
    anti-dilutive.



(2) The pro forma balance sheet data give effect to our reorganization from an
    LLC to a corporation as though the reorganization had occurred as of June
    30, 1999.



(3) Pro forma as adjusted amounts reflect the sale of 3,125,000 shares of common
    stock in this offering, after deducting estimated underwriting discounts and
    commissions and estimated offering expenses payable by us.


(4) Our working capital balances are typically negative because of the timing of
    cash collections from clients. SPS contracts are typically annual and paid
    in advance. Accordingly, a substantial portion of our billings is initially
    recorded as deferred revenue and amortized into revenue during the term of
    the contract to which such billings relate.

                                  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 events actually occurs, our
business and financial results may suffer. In this case, the market price of our
common stock could decline, and you could lose all or part of your investment in
our common stock.

IF WE ARE UNABLE TO ATTRACT AND RETAIN EXPERIENCED PERSONNEL, THE QUALITY OF OUR
RESEARCH PRODUCTS AND SERVICES MAY DECLINE, AND OUR ABILITY TO SELL OUR PRODUCTS
AND SERVICES MAY BE HARMED.

     Our success depends in large part on the continued contributions of our
senior management team, research analysts and sales representatives. As of June
30, 1999, we had 38 research analysts and 40 sales representatives. We expect to
increase our hiring of research analysts and sales representatives significantly
in the next few years. We face intense competition in hiring and retaining
personnel from, among others, technology and Internet companies, market research
and consulting firms, print and electronic publishing companies and financial
services companies. Many of these firms have substantially greater financial
resources than we do to attract and retain qualified personnel from a limited
pool of attractive candidates. In addition, some people that we may attempt to
hire could be subject to non-competition agreements that could impede our
recruitment efforts. To the extent that we are unable to retain our existing
management, research analysts or sales representatives or that we are unable to
increase the number of research analysts and sales representatives that we hire,
our business and financial results may suffer.

BECAUSE WE HAVE RECENTLY INTRODUCED MANY OF OUR PRODUCTS AND SERVICES, YOU HAVE
LIMITED INFORMATION UPON WHICH YOU CAN EVALUATE OUR BUSINESS.


     We have recently launched many of the practices and market modules that we
offer. As a result, we have a limited operating history upon which you can
evaluate our business and the products and services that we offer. Due to our
limited operating history, it is difficult or impossible for us to predict
future results of operations. Moreover, due to our limited operating history,
any evaluation of our business and prospects must be made in light of the risks
and uncertainties frequently encountered by companies in new and rapidly
evolving markets such as ours. Many of these risks and uncertainties are
discussed elsewhere in this section. We cannot assure you that we will be
successful in addressing these risks and uncertainties. Our failure to do so
could cause our business and financial results to suffer.


RAPID GROWTH IN OUR BUSINESS COULD STRAIN OUR MANAGERIAL, OPERATIONAL AND
FINANCIAL RESOURCES.


     The anticipated future growth of our business will place a significant
strain on our managerial, operational and financial resources. We had 61
employees at December 31, 1996, 88 employees at December 31, 1997, 142 employees
at December 31, 1998 and 194 employees at June 30, 1999. We anticipate hiring a
substantial number of research analysts, sales representatives and other
employees in the foreseeable future to expand our product and service offerings
and to expand our sales of such products and services. We may also decide to
open additional offices in the United States and abroad. As we expand, we expect
that we will need to continually improve our financial and managerial controls,
billing systems, reporting systems and procedures. In addition, as we expand we
will also need to increase our employee training efforts. If we are unable to
manage our growth effectively, our business and financial results may suffer.


WE HAVE A HISTORY OF OPERATING LOSSES WHICH MAY CONTINUE FOR THE FORESEEABLE
FUTURE.


     We have incurred substantial costs to create, market and distribute our
products and services, to retain qualified personnel, including management,
research analysts and sales representatives, and to grow our business. As a
result, we incurred net losses of approximately $613,000 in 1996, $2.3 million
in 1997, $2.1 million in 1998 and $130,000 for the six month period ended June
30, 1999. As a percentage of total

                                        8
<PAGE>   10


revenues, our net losses equaled 9.8% in 1996, 26.4% in 1997, 14.4% in 1998 and
0.9% for the six month period ended June 30, 1999. As of June 30, 1999, our
accumulated deficit totaled $5.8 million.


     We intend to invest heavily in new products and services, leasehold and
technology improvements, new research and sales personnel and international
expansion. As a result, we will need to achieve significant revenue increases to
achieve and maintain profitability. The number of clients for our research
products and services, as well as the number of attendees to our conferences,
may grow more slowly than we anticipate or may even decrease in the future. In
addition, even if we become profitable, we may not sustain or increase our
profits on a quarterly or annual basis in the future.

OUR OPERATING RESULTS MAY FLUCTUATE IN FUTURE PERIODS, WHICH MAY CAUSE
VOLATILITY OR A DECLINE IN THE PRICE OF OUR STOCK.


     Our revenues, expenses and operating results have varied in the past and
may fluctuate significantly in the future due to a variety of factors that are
outside of our control. These factors include, among others:



     - the level and timing of new business and renewals of subscriptions to our
       research products and services;


     - changes in the market demand for research products or analysis regarding
       Internet commerce;


     - the levels of attendance at our Internet conferences; and


     - the extent to which we experience increased competition.


     The above factors could affect our quarterly as well as long-term financial
results. In particular, changes in the demand for our products, competition or
the levels of attendance at our Internet conferences each could have both
short-term and long-term adverse effects on our business.



     Our revenues, expenses and operating results may also fluctuate
significantly in the future as a result of business decisions made by us. These
decisions include, among others:



     - the timing of the introduction and marketing of our new research products
       and services;



     - the timing of our conferences;



     - changes in operating expenses; and



     - the timing of acquisitions and the impact on our operations and our
       operating results.



     The sales of our research products and services and the success of our
conferences are difficult to forecast accurately. If our revenues fall short of
expectations, we may not be able to adjust our fixed expenses, which represented
approximately 45% of our total expenses for the six months ended June 30, 1999,
to compensate for this shortfall on a timely basis. Further, as a strategy for
remaining competitive, we may have to make pricing, service or marketing
decisions that could cause our business and financial results to suffer.



     Due to all the foregoing factors and other risks discussed in this section,
you should not rely on quarter-to-quarter comparisons of our results of
operations as an indication of future performance. It is possible that in some
future periods our results of operations may be below the expectations of
investors. In this event, the price of our common stock is likely to fall.


BECAUSE OUR REVENUES ARE SUBSTANTIALLY DEPENDENT ON THE SALE OF OUR STRATEGIC
PLANNING SERVICES, OUR BUSINESS MAY SUFFER IF WE HAVE DIFFICULTY IN ACQUIRING OR
RETAINING SUBSCRIBERS TO THIS PROGRAM.


     Our business and financial results are dependent on our ability to attract
and retain clients for our Strategic Planning Services. In addition, our
business model assumes that we will be able to increase the level of SPS sales
over time to our existing clients. Revenues from subscriptions to SPS, as a
percentage of our total revenues, were 41.8% in 1998 and 56.7% in the six months
ended June 30, 1999.


                                        9
<PAGE>   11

     Our ability to acquire and retain SPS clients and our ability to increase
sales to existing clients is subject to a number of risks, including the
following:

     - We may be unsuccessful in delivering high-quality and timely research
       analysis to our clients;

     - We may be unsuccessful in anticipating and understanding market trends
       and the changing needs of our clients;

     - The use of the Internet as a medium for commerce, both in the United
       States and abroad, may not continue to grow as we currently anticipate;

     - Our marketing programs designed to attract and retain clients may not
       succeed; and

     - We may not be able to hire and retain a sufficiently large number of
       research and sales personnel in a very competitive job market.

     If we are unable to retain existing clients, increase sales to existing
clients or attract a significant number of new SPS clients, our business and
financial results may suffer.

OUR BUSINESS MAY SUFFER IF WE PROVE UNABLE TO ANTICIPATE MARKET TRENDS OR IF WE
FAIL TO PROVIDE INFORMATION THAT IS USEFUL TO OUR CLIENTS.

     Our success depends in large part on our ability to anticipate, research
and analyze rapidly changing technologies and industries and on our ability to
provide this information in a timely and cost-effective manner. If we are unable
to continue to provide credible and reliable information that is useful to
companies engaged in online commerce, our business and financial results may
suffer.


     Our research products and services, as well as our conferences, focus on
Internet commerce. Internet commerce is relatively new and is undergoing
frequent and dramatic changes, including the introduction of new products and
the obsolescence of others, shifting business strategies and revenue models, the
formation of numerous new companies and high rates of growth. Because of these
rapid and continuous changes in the Internet commerce markets, we face
significant challenges in providing timely analysis and advice. Many of the
industries and areas on which we focus are relatively new, and it is very
difficult to provide predictions and projections as to the future marketplace,
revenue models and competitive factors. In addition, many companies have not
embraced the use of the Internet as a medium for commerce and are unclear as to
how to allocate corporate resources effectively. As a result, some companies may
conclude that our research products are not useful to their businesses. Further,
the need to continually update our research requires the commitment of
substantial financial and personnel resources.


     If our predictions or projections prove to be wrong, or if we are unable to
continually update our information, our reputation may suffer and demand for our
research products and services may decline. In addition, if companies do not
agree with our analysis of market trends and the areas on which we choose to
focus our efforts, our business and financial results may suffer.

WE FACE INTENSE COMPETITION IN PROVIDING OUR RESEARCH PRODUCTS AND SERVICES, AS
WELL AS IN PRODUCING CONFERENCES, AND SUCH COMPETITION IS LIKELY TO INCREASE IN
THE FUTURE.


     We may not be able to compete successfully against current or future
competitors, and the competitive pressures that we face may cause our business
and financial results to suffer. Our principal current competitor is Forrester
Research, Inc. Recently Gartner Group, Inc. announced its intention to compete
directly in providing research products related to Internet commerce. A number
of other companies compete with us in providing research and analysis related to
a specific industry or geographic area. In addition, our competitors include
information technology research firms, business consulting and accounting firms,
electronic and print publishing companies and equity analysts employed by
financial services companies.


     Our ability to compete both in the United States and abroad depends upon
many factors, many of which are outside of our control. We believe that the
primary competitive factors determining success in

                                       10
<PAGE>   12

our markets include the quality and timeliness of our research and analysis, our
ability to offer products and services that meet the changing needs of our
customers, the prices we charge for our various research products and general
economic conditions.

     We expect competition to increase because of the business opportunities
presented by the growth of Internet commerce around the world. Competition may
also intensify as a result of industry consolidation, because the markets in
which we operate face few substantial barriers to entry or because some of our
competitors may provide additional or complementary services, such as consulting
services. Increased competition may result in reduced operating margins, loss of
market share and diminished value in our products and services, as well as
different pricing, service or marketing decisions.

     Our current and potential competitors include many companies that have
substantially greater financial, information gathering and marketing resources
than we have. This may allow them to devote greater resources than we can to the
promotion of their brand and to the development and sale of their products and
services. We cannot assure you that we will be able to compete successfully
against current and future competitors.


WE EXPECT GARTNER GROUP, OUR LARGEST SHAREHOLDER, WHICH HAS BEEN PROVIDED WITH
CONFIDENTIAL AND PROPRIETARY INFORMATION, TO COMPETE DIRECTLY WITH US AND
POSSIBLY TO USE ITS VOTING POWER IN A WAY THAT WOULD NEGATIVELY AFFECT OUR
ABILITY TO OPERATE OUR BUSINESS.



     Gartner Group, which historically has focused on information technology
research, has recently announced its intention to begin offering broader
research products and services related to Internet commerce. These products and
services are likely to compete directly with the products and services that we
offer. Under the operating agreement governing Jupiter Communications, LLC,
Gartner Group has the right to appoint two of the five representatives of the
board of members and has the right to consent to various actions taken by us.
Following the closing of this offering, Gartner Group will not retain the right
to appoint a member of our board of directors or any other specific rights,
other than piggyback registration rights and limited indemnification rights.
Following this offering, Gartner Group will be our largest shareholder, owning
approximately 28.4% of our outstanding common stock. However, for a period of
one year following the closing of this offering, Gartner Group and its
affiliates may not acquire, directly or indirectly, any additional common stock,
if the acquisition would cause Gartner Group and its affiliates to own more than
32% of our common stock.


     Although Gartner Group has not been actively involved in our day-to-day
operations since it first invested in our company in October 1997, it has been
provided with our confidential and proprietary data during most of this period.
As a result, Gartner Group could use our confidential and proprietary data in
developing and marketing competing products and services. Gartner Group could
also use its voting power in a way that would negatively affect our ability to
operate our business or have the effect of delaying, deterring or preventing a
change in control, or impeding a merger, consolidation, takeover or other
business combination. Gartner Group has substantially greater financial
resources than we do, which may allow it to devote greater resources than we can
to the development and sale of their Internet commerce research.


IF INTERNET USAGE DOES NOT CONTINUE TO GROW, OUR BUSINESS AND FINANCIAL RESULTS
MAY SUFFER.



     Our future success depends on continued growth in the use of the Internet.
We cannot be certain that Internet usage will continue to grow at or above its
historical rates. Internet usage may be inhibited for a number of reasons,
including:


     - inadequate network infrastructure;

     - inconsistent quality of service; and


     - lack of availability of cost-effective, high-speed service.


                                       11
<PAGE>   13


OUR BUSINESS MAY SUFFER IF THE USE OF THE INTERNET AS A COMMERCIAL MARKETPLACE
DOES NOT CONTINUE TO GROW.



     Because our company focuses solely on Internet commerce, our future success
depends on the continued development and acceptance of the Internet as a viable
commercial medium. However, the continued development and acceptance of the
Internet as a widely-used medium for commerce and communication is uncertain. A
number of factors could prevent such continued development and acceptance,
including the following:


     - unwillingness of companies and consumers to shift their purchasing from
       traditional vendors to online vendors;

     - security and authentication concerns with respect to the transmission of
       confidential information, such as credit card numbers, over the Internet;

     - privacy concerns, including those related to the ability of Web sites to
       gather user information without the user's knowledge or consent; and

     - significant uncertainty about the demand and market acceptance for
       Internet advertising and the lack of standards to measure the
       effectiveness of Internet advertising.


LAWS AND REGULATIONS COULD SLOW THE GROWTH OF THE INTERNET AND NEGATIVELY AFFECT
THE ACCEPTANCE OF THE INTERNET AS A COMMERCIAL MEDIUM.



     Laws and regulations regarding Internet companies and commercial
transactions conducted over the Internet could slow the growth in use of the
Internet generally and decrease the acceptance of the Internet as a commercial
medium. For example, as the popularity and use of the Internet increases, it is
possible that a number of laws and regulations may be adopted in the United
States or in other countries covering issues such as taxation, intellectual
property matters, advertising and other areas. We cannot predict the impact, if
any, that future laws or regulations may have on our business.


WE COULD FACE ADDITIONAL RISKS AND CHALLENGES IF WE CONTINUE TO EXPAND
INTERNATIONALLY.

     Our business plan calls for increased international growth. Expansion into
new geographic territories requires considerable management and financial
resources and may negatively impact our near-term results of operations.

     Our current international operations, as well as any future international
operations, are subject to numerous challenges and risks, including, but not
limited to, the following:

     - political and economic conditions in various jurisdictions;

     - fluctuations in currency exchange rates;

     - tariffs and other trade barriers;

     - adverse tax consequences; and

     - difficulties in protecting intellectual property rights in international
       jurisdictions.

     We cannot assure you that one or more of these factors would not harm any
current or future international operations.

OUR BUSINESS MAY SUFFER IF WE ARE UNABLE TO MAINTAIN OR ENHANCE AWARENESS OF THE
JUPITER BRAND OR IF WE INCUR EXCESSIVE EXPENSES ATTEMPTING TO PROMOTE THE
JUPITER BRAND.

     We expect to use a portion of the proceeds of this offering to expand our
marketing activities to promote and strengthen the Jupiter brand. Promoting and
strengthening the Jupiter brand is critical to our efforts to attract and retain
clients for our research products, as well as to increase attendance at our
conferences. We believe that the importance of brand recognition will likely
increase due to the increasing

                                       12
<PAGE>   14

number of competitors entering our markets. In order to promote the Jupiter
brand, in response to competitive pressures or otherwise, we may find it
necessary to increase our marketing budget, hire additional marketing and public
relations personnel or otherwise increase our financial commitment to creating
and maintaining brand loyalty among our clients. If we fail to effectively
promote and maintain the Jupiter brand, or incur excessive expenses attempting
to promote and maintain the Jupiter brand, our business and financial results
may suffer.

WE FACE POTENTIAL LIABILITY FOR INFORMATION THAT WE PUBLISH, PROVIDE AT
CONFERENCES OR DISSEMINATE THROUGH OUR RESEARCH ANALYSTS.

     As a publisher and distributor of original research, market projections and
trend analyses, we face potential liability based on a variety of theories,
including defamation, negligence, copyright or trademark infringement or other
legal theories based on the nature, publication or distribution of this
information. Such claims, whether brought in the United States or abroad, would
likely divert management time and attention and result in significant cost to
investigate and defend, regardless of the merit of any such claims. The filing
of any such claims may also damage our reputation as a high-quality provider of
unbiased, timely analysis and result in client cancellations or overall
decreased demand for our products and services. In addition, if we become
subject to these types of claims and are not successful in our defense, we may
be forced to pay substantial damages. Our insurance may not adequately protect
us against these claims.

DISRUPTION OF OUR WEB SITE DUE TO SECURITY BREACHES AND SYSTEM FAILURES COULD
HARM OUR BUSINESS AND RESULT IN CLIENT CANCELLATIONS.

     Our infrastructure and the infrastructure of our service providers are
vulnerable to security breaches, computer viruses or similar disruptive problems
and system failures. These systems are also subject to telecommunications
failures, power loss and various other events. Any of these events, whether
intentional or accidental, could lead to interruptions or disruptions in the
general operation of our business. In addition, any of these events could also
lead to interruptions, delays or cessation of operation of our Web site, which
provides access to and distribution of many of our research products and
services. For example, many of our SPS clients pay us so that their employees
can read our research solely on our Web site. As a result, providing unimpeded
access to our Web site is critical to servicing our clients and providing
superior customer service. Our inability to provide continuous access to our Web
site could cause some of our clients to discontinue purchasing our research
products and services, prevent or deter some people from purchasing our research
products and services and harm our business reputation.

WE ARE DEPENDENT ON KEY MANAGEMENT PERSONNEL FOR OUR FUTURE SUCCESS.

     Our future success will depend in part on the continued service of a number
of key management personnel. We do not carry key person life insurance on any of
our management personnel. The loss of key management personnel, in particular
Gene DeRose, our Chief Executive Officer, or Kurt Abrahamson, our President and
Chief Operating Officer, could harm our business and financial results.

IF WE FAIL TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY OR FACE A CLAIM OF
INTELLECTUAL PROPERTY INFRINGEMENT BY A THIRD PARTY, WE MAY LOSE OUR
INTELLECTUAL PROPERTY RIGHTS AND BE LIABLE FOR SIGNIFICANT DAMAGES.


     We provide our proprietary research products to hundreds of different
companies throughout the world, including some companies that compete with us in
some manner. As a result, any protective steps we have taken may be inadequate
to protect our intellectual property and to deter misappropriation of the
original research and analysis that we develop. We also may be unable to detect
the unauthorized use of our intellectual property or take appropriate steps to
enforce our intellectual property rights. Moreover, effective trademark,
copyright and trade secret protection may not be available in every country in
which we offer our research products and services to the extent these
protections are available in the United States.


                                       13

     Our failure to adequately protect our intellectual property, either in the
United States or abroad, could harm the Jupiter brand or our trademarks, devalue
our proprietary research and analysis and affect our ability to compete
effectively. Defending our intellectual property rights could result in the
expenditure of significant financial and managerial resources, which could harm
our financial results.


     Furthermore, other parties may assert claims against us that we have
misappropriated a trade secret or infringed a patent, copyright, trademark or
other proprietary right belonging to them. Any infringement or related claims,
even if not meritorious, could be costly and time consuming to litigate, may
distract management from other tasks of operating the business and may result in
the loss of significant rights and the loss of our ability to operate our
business.


WE MAY NOT BE ABLE TO SUCCESSFULLY MAKE ACQUISITIONS OF OTHER COMPANIES,
SERVICES OR PRODUCTS.

     We have limited experience in acquiring other companies, services or
products. Although we have no present understanding or agreement relating to any
acquisition, we do anticipate making acquisitions in the future. We cannot
assure you, however, that we will be able to complete future acquisitions
successfully or to integrate an acquired entity with our current business. In
addition, the key personnel of the acquired company may decide not to work for
us. If we make other types of acquisitions, we could have difficulty
assimilating the acquired services or products. These difficulties could disrupt
our current business, distract our management and employees, increase our
expenses and adversely affect our results of operations. Furthermore, we may
incur debt or issue equity securities to pay for any future acquisitions. The
issuance of equity securities could be dilutive to our existing shareholders.

OUR DIRECTORS, OFFICERS AND PRINCIPAL STOCKHOLDERS WILL EXERCISE SIGNIFICANT
CONTROL OVER US FOLLOWING THIS OFFERING.


     Upon completion of this offering, our officers, directors and existing
stockholders who own greater than 5% of the outstanding common stock before this
offering, and entities affiliated with them, will, in the aggregate,
beneficially own approximately 74.2% of our common stock. In particular, Gartner
Group will own approximately 28.4% of our outstanding common stock. These
stockholders acting together will be able to exert substantial influence over
all matters requiring approval by our stockholders. These matters include the
election and removal of directors and any merger, consolidation or sale of all
or substantially all of our assets. In addition, they may dictate the management
of our business and affairs. This concentration of ownership could have the
effect of delaying, deferring or preventing a change in control, or impeding a
merger, consolidation, takeover or other business combination.


PROBLEMS RESULTING FROM THE YEAR 2000 PROBLEM COULD REQUIRE US TO INCUR
UNANTICIPATED EXPENSES AND COULD DIVERT MANAGEMENT'S TIME AND ATTENTION.


     The Year 2000 problem could harm our business and financial results. 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
interpret the date code "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 or replaced to comply with Year 2000
requirements or risk system failure or miscalculations causing disruptions of
normal business activities. Our failure to correct a Year 2000 problem could
result in an interruption in, or a failure of, aspects of our normal business
activities or operations. Any significant Year 2000 problem could require us to
incur significant unanticipated expenses to remedy these problems and could
divert management's time and attention. We consider the reasonably likely
worst-case scenario to be interruptions in telecommunications networks,
including the Internet. Due to our reliance on the Internet and other
telecommunications networks to keep in contact with our clients and for general
business uses, these interruptions could cause our business to suffer. We have
not developed a contingency plan to address Year 2000 issues. Please see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Year 2000 Compliance" for detailed information on our state of
readiness and potential risks regarding the Year 2000 issue.

FUTURE SALES OF OUR COMMON STOCK MAY NEGATIVELY AFFECT OUR STOCK PRICE.


     Following this offering, we will have a large number of shares of common
stock outstanding and available for resale beginning at various points of time
in the future. Our largest stockholder, Gartner Group, may be able to sell as
many as 3,515,624 shares of our common stock in the public market beginning 90
days after the date of this prospectus. The market price of our common stock
could decline as a result of sales of a large number of shares of our common
stock in the market following this offering, or the perception that such sales
could occur. In addition, these sales also might make it more difficult for us
to sell equity securities in the future at a price that we think is appropriate,
or at all. Please see "Shares Eligible for Future Sale."


THERE HAS BEEN NO PRIOR MARKET FOR OUR COMMON STOCK, AND OUR STOCK MAY
EXPERIENCE EXTREME PRICE AND VOLUME FLUCTUATIONS.

     The stock market has experienced extreme price and volume fluctuations. The
market prices of the securities of Internet-related companies have been
especially volatile. Prior to this offering, there has been no public market for
our common stock. We cannot predict the extent to which investor interest in
Jupiter will lead to the development of an active trading market or how liquid
that market might become. The market price of the common stock may decline below
the initial public offering price. The initial public offering price for the
shares will be determined by negotiations between us and the representatives of
the underwriters and may not be indicative of prices that will prevail in the
trading market. Please see "Underwriting."

     In the past, companies that have experienced volatility in the market price
of their stock have been the object of securities class action litigation. If we
were the object of securities class action litigation, it could result in
substantial costs and a diversion of our management's attention and resources.


WE WILL HAVE BROAD DISCRETION AS TO THE USE OF THE PROCEEDS FROM THIS OFFERING,
WHICH WE MAY NOT USE EFFECTIVELY.


     We intend to spend a significant portion of the net proceeds of this
offering for product development, international expansion, research, sales and
marketing expansion, leasehold and technology improvements, potential
acquisitions and general corporate purposes. Our management will have broad
discretion, however, over the allocation of a substantial portion of the net
proceeds from this offering as well as over the timing of our expenditures.
Investors may not agree with the way our management decides to spend these
proceeds. Please see "Use of Proceeds."

WE CANNOT PREDICT OUR FUTURE CAPITAL NEEDS, AND WE MAY NOT BE ABLE TO SECURE
ADDITIONAL FINANCING.

     We currently anticipate that the net proceeds of this offering, together
with available funds, will be sufficient to meet our anticipated needs for the
next 12 months. We may need to raise additional funds in the future to fund our
operations, to expand or enhance the range of products and services we offer or
to respond to competitive pressures and/or perceived opportunities. We cannot be
sure that additional financing will be available on terms favorable to us, or at
all. If adequate funds are not available when required or on acceptable terms,
we may be forced to cease our operations, and even if we are able to continue
our operations, our business and financial results may suffer.

WE HAVE ANTI-TAKEOVER PROVISIONS WHICH MAY MAKE IT DIFFICULT FOR A THIRD PARTY
TO ACQUIRE US.

     Provisions of our certificate of incorporation, our bylaws and Delaware law
could make it more difficult for a third party to acquire us, even if doing so
might be beneficial to our stockholders. Please see "Description of Capital
Stock."

INVESTORS IN THIS OFFERING WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION.

     Investors purchasing shares in this offering will suffer immediate and
substantial dilution in net tangible book value per share. To the extent
outstanding options to purchase common stock are exercised, there will be
further dilution. Please see "Dilution."


WE DO NOT PLAN TO PAY DIVIDENDS IN THE FORESEEABLE FUTURE.



     We have not declared or paid any cash dividends on our capital stock since
inception. We intend to retain any future earnings to finance the operation and
expansion of our business and do not anticipate paying any cash dividends in the
foreseeable future.


                           FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements which involve risks and
uncertainties. These forward-looking statements are usually accompanied by words
such as "believes," "anticipates," "plans," "expects" and similar expressions.
Our actual results could differ materially from those expressed or implied by
these forward-looking statements as a result of various factors, including the
risk factors described above and elsewhere in this prospectus.

                                USE OF PROCEEDS


     We estimate that we will receive net proceeds from the sale of the shares
of common stock in this offering of $45.4 million, assuming an initial public
offering price of $16.00 per share and after deducting estimated underwriting
discounts and commissions and estimated offering expenses. If the underwriters
exercise their over-allotment option in full, we estimate that our net proceeds
will be $52.4 million.



     As of the date of this prospectus, we have not made any specific
expenditure plans with respect to the proceeds of this offering. Therefore, we
cannot specify with certainty the particular uses for the net proceeds to be
received upon completion of this offering. Accordingly, our management will have
significant flexibility in applying the net proceeds of the offering.



     We currently intend to use the proceeds from this offering over time for
product development, international expansion, research, sales and marketing
expansion, leasehold and technology improvements, potential acquisitions and
general corporate purposes. We have no present commitments and are not currently
engaged in any negotiations with respect to such acquisitions. Pending any use,
we intend to invest the net proceeds of this offering in short-term,
interest-bearing securities.


                                DIVIDEND POLICY

     We have never declared or paid any cash dividends on our common stock. We
currently anticipate that we will retain any future earnings for the development
and operation of our business. Accordingly, we do not anticipate declaring or
paying any cash dividends in the foreseeable future.

offering price of $16.00 per share, after deducting estimated underwriting

                                    DILUTION


     Our net tangible book value as of June 30, 1999 was approximately
$(1,924,060), or $(0.18) per share of common stock. Net tangible book value per
share is determined by dividing the amount of our total tangible assets less
total liabilities by the weighted average pro forma number of shares of common
stock outstanding at that date. The pro forma weighted average number of shares
of common stock outstanding gives effect to the Company's reorganization from an
LLC to a corporation as though the reorganization had occurred as of June 30,
1999. Dilution in net tangible book value per share represents the difference
between the amount per share paid by purchasers of shares of common stock in
this offering and the net tangible book value per share of common stock
immediately after the completion of this offering.



     After giving effect to the issuance and sale of the shares of common stock
offered by us at an estimated initial public offering price of $16.00 per share
and after deducting estimated underwriting discounts and commissions and
estimated offering expenses payable by us, and the application of the estimated
net proceeds from this offering, our pro forma net tangible book value as of
June 30, 1999 would have been $43,475,940 or $3.12 per share. This represents an
immediate increase in pro forma net tangible book value to our existing
stockholders of $3.30 per share and an immediate dilution to purchasers in this
offering of $12.88 per share. If the initial public offering price is higher or
lower, the dilution to purchasers in this offering will be greater or less,
respectively.


     The following table illustrates this per share dilution:

</TABLE>



     Assuming the exercise in full of the underwriters' over-allotment option,
our adjusted pro forma net tangible book value at June 30, 1999 would have been
approximately $3.50 per share, representing an immediate increase in pro forma
net tangible book value of $3.68 per share to our existing stockholders and an
immediate dilution in pro forma net tangible book value of $12.50 per share to
purchasers in this offering.



     The following table summarizes, on a pro forma basis, as of June 30, 1999,
the differences between the number of shares of common stock purchased from us,
the aggregate cash consideration paid to us and the average price per share paid
by existing stockholders and new investors purchasing shares of common stock in
this offering. The calculation below is based on an assumed initial public
offering price of $16.00 per share, before deducting estimated underwriting
discounts and commissions and estimated offering expenses payable by us:

(1) Pro forma basic and diluted net loss per common share is computed by
    dividing net loss by the pro forma weighted average number of shares of
    common stock. Pro forma weighted average number of shares of common stock
    gives effect to our reorganization from an LLC to a corporation as though
    the reorganization had occurred as of the beginning of each period
    indicated. Pro forma weighted average shares do not include any common stock
    equivalents because inclusion of common stock equivalents would have been
    anti-dilutive.


(2) Our working capital balances are typically negative because of the timing of
    cash collections from clients. SPS contracts are typically annual and paid
    in advance. Accordingly, a substantial portion of our billings is initially
    recorded as deferred revenue and amortized into revenue during the term of
    the contract to which such billings relate.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

     You should read the following discussion of our financial condition and
results of operations together with our financial statements, the notes to those
statements and the other information in this prospectus. This discussion
contains forward-looking statements that involve risks and uncertainties. Please
see "Risk Factors."

OVERVIEW


     We are a leading provider of research on Internet commerce, as measured by
both revenue and number of clients. Senior executives at our client companies
utilize our research to make informed business decisions in a complex and
rapidly changing Internet economy. Our research, which is focused solely on the
Internet economy, provides our clients with comprehensive views of industry
trends, forecasts and best practices. Our analysis, supported by proprietary
data, emphasizes specific, actionable findings.



     Our revenues consist of SPS, conferences and other revenues. For the six
months ended June 30, 1999, SPS represented approximately 56.7% of our total
revenues. SPS is a combination of proprietary written analysis, supporting data
and access to our analysts. We typically bill clients annually in advance and
deliver the products and services over the term of the contract. We also produce
a wide range of conferences which offer senior executives the opportunity to
hear first-hand the insights of our analysts and the leading decision makers in
the Internet and technology industries. Conference revenues consist of revenues
from individual attendees, sponsors, which display their logo in our conference
program and/or host a reception, and exhibitors, which receive a booth to
promote their companies. For the six months ended June 30, 1999, conferences
represented approximately 31.6% of our total revenues. Other revenues, which
consist primarily of book-length studies, newsletters and custom research,
represented approximately 11.7% of our total revenues for the six months ended
June 30, 1999.


     SPS contracts are renewable contracts, typically annual, and payable in
advance. Accordingly, a substantial portion of our billings is initially
recorded as deferred revenue and amortized into revenue over the term of the
contract. Commission expense related to SPS is also initially deferred and
amortized into expense over the contract period in which the related revenues
are earned and amortized to income. Our contracts are non-cancelable and
non-refundable. Billings attributable to our conferences and other products and
services are initially recorded as deferred revenue and recognized upon the
completion of the event or project.


     We have experienced rapid growth since our organization, and particularly
since our decision in late 1996 to focus our business on SPS. Between 1995 and
1998, our total revenues have grown from $3.7 million to $14.8 million, a
compound annual growth rate of 59.2%. For the six months ended June 30, 1999,
our revenues were $14.4 million, representing an increase of 143.5% over
revenues of $5.9 million for the six months ended June 30, 1998. The number of
our SPS contracts has increased from 145 as of December 31, 1997 to 654 as of
June 30, 1999. Our total contract value has increased from $2.5 million on
December 31, 1997 to $22.1 million on June 30, 1999. We believe that total
contract value is a meaningful measure of the volume of our business. Total
contract value, however, does not necessarily correlate to deferred revenues.
Total contract value represents the annualized value of all outstanding SPS
contracts without regard to the remaining duration of such contracts, and
deferred revenue represents unamortized revenue remaining on all outstanding and
billed contracts.



     To date, a substantial portion of expiring SPS contracts have been renewed
for an equal or higher amount. Approximately 73% of contracts expiring during
the 12 months ended June 30, 1999 were renewed. Approximately 95% of the
contracts that were renewed in the first six months of 1999 were for an equal or
larger dollar amount. With this high customer renewal rate, we believe we have a
growing base of recurring revenues from SPS. However, this renewal rate is not
necessarily indicative of the rate of future retention of our revenue base.


                                       22
<PAGE>   24

     We have a highly diversified client base, including companies in the
Internet, media, telecommunications, technology, financial services, retail,
travel, consumer products and professional services industries. No client
accounts for more than 2% of our total annual revenues.

     Cost of services and fulfillment represents the costs associated with
production and delivery of our products and services, including the costs of
salaries, bonuses and related benefits for our research and conference
personnel, all associated editorial, travel and support services, and the costs
of producing our conferences. Sales and marketing expenses include salaries,
bonuses, employee benefits, travel expenses, promotional costs, sales
commissions and other costs incurred in marketing and selling our products and
services. General and administrative expenses include the costs of our finance
and technology groups and other administrative functions.


     We have incurred net losses since our formation. Our net loss was $613,000
in 1996, $2.3 million in 1997, $2.1 million in 1998 and $130,000 for the six
months ended June 30, 1999. We expect to incur a net loss for the full year
1999. As of June 30, 1999, we had an accumulated deficit of $5.8 million. We
expect to incur significant expenditures in the future associated with our
domestic and international expansion strategies. In particular, we intend to
continue to expand our research and sales personnel, and we intend to continue
to invest in technology, leasehold improvements and the development of
additional research practices and modules.

     The following table sets forth our results of operations for the years
ended December 31, 1996, 1997 and 1998 and the six months ended June 30, 1998

  COMPARISON OF SIX MONTHS ENDED JUNE 30, 1999 AND 1998



     Revenues.  Total revenues increased 143.5% to $14.4 million in the six
months ended June 30, 1999 from $5.9 million in the six months ended June 30,
1998. SPS revenues increased 309.3% to $8.2 million in the six months ended June
30, 1999 from $2.0 million in the six months ended June 30, 1998. This increase
is attributable primarily to an increase in the number of SPS contracts to 654
at June 30, 1999 from 219 at June 30, 1998 and an increase in average contract
value to $33,850 at June 30, 1999 from


                                       23
<PAGE>   25


$23,235 at June 30, 1998. These increases reflect an increase in the number of
users at, and research services purchased by, our client companies. Total
contract value increased to $22.1 million at June 30, 1999 from $5.1 million at
June 30, 1998.



     Conference revenues increased 130.1% to $4.6 million in the six months
ended June 30, 1999 from $2.0 million in the six months ended June 30, 1998.
These revenues reflect the results of four conferences in the six months ended
June 30, 1998 and five conferences in the six months ended June 30, 1999. The
increase is attributable to an increase in attendee, sponsor and exhibitor
revenues and the production of an additional conference in the six months ended
June 30, 1999.



     Other revenues decreased 13.3% to $1.7 million in the six months ended June
30, 1999 from $1.9 million in the six months ended June 30, 1998. This decrease
reflects our decision to focus our business on SPS.



     Cost of Services and Fulfillment.  Cost of services and fulfillment
increased 60.1% to $6.9 million in the six months ended June 30, 1999 from $4.3
million in the six months ended June 30, 1998. The increase in this period was
attributable to the overall growth of our business, in particular the increased
research staffing for new and existing research practices. Gross margin
increased to 52.4% in the six months ended June 30, 1999 from 27.6% in the six
months ended June 30, 1998 because the growth in our client base and new
business exceeded the growth in the cost of providing our research services and
conferences.



     Sales and Marketing.  Sales and marketing expenses increased 205.2% to $4.0
million in the six months ended June 30, 1999 from $1.3 million in the six
months ended June 30, 1998. As a percentage of total revenues, these expenses
increased to 27.8% in the six months ended June 30, 1999 from 22.2% in the six
months ended June 30, 1998. The increase in this period was primarily
attributable to an increased number of sales personnel and the corresponding
commission costs associated with increased revenues.



     General and Administrative.  General and administrative expenses increased
91.2% to $3.7 million in the six months ended June 30, 1999 from $1.9 million in
the six months ended June 30, 1998. As a percentage of total revenues, these
expenses decreased to 25.5% in the six months ended June 30, 1999 from 32.4% in
the six months ended June 30, 1998. The increase in this period was primarily
attributable to increased personnel for the finance, human resources and
operations areas, as well as costs associated with our new London office and
higher costs for staff travel and professional fees.


  COMPARISON OF THE YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996

     Revenues.  Total revenues increased 73.7% to $14.8 million in 1998 from
$8.5 million in 1997 and 36.3% to $8.5 million in 1997 from $6.3 million in
1996. SPS revenues increased by 234.2% to $6.2 million in 1998 from $1.9 million
in 1997. This increase is attributable primarily to an increase in the number of
SPS contracts to 421 at December 31, 1998 from 145 at December 31, 1997 and an
increase in average contract value to $27,700 at December 31, 1998 from $17,300
at December 31, 1997. SPS revenues increased by 227.1% to $1.9 million in 1997
from $566,000 in 1996. This increase is attributable primarily to an increase in
the number of SPS contracts to 145 at December 31, 1997 from 66 at December 31,
1996 and an increase in average contract value to $17,300 at December 31, 1997
from $14,000 at December 31, 1996.

     The increase in SPS revenues in these periods reflects an increase in the
number of users at, and research services purchased by, our client companies.
Total contract value increased to $11.7 million at December 31, 1998 from $2.5
million at December 31, 1997 and $923,000 at December 31, 1996.


     Conference revenues increased 42.7% to $4.9 million in 1998 from $3.4
million in 1997 and 27.6% to $3.4 million in 1997 from $2.7 million in 1996.
These increases are attributable to an increase both in the number of
conferences and in average attendee, sponsor and exhibitor revenues.


                                       24
<PAGE>   26

     Other revenues increased 14.9% to $3.7 million in 1998 from $3.2 million in
1997. This increase reflects an increase in revenues from custom research and
book-length studies, offset in part by a small decrease in newsletter revenues.
Other revenues increased 8.2% to $3.2 million in 1997 from $3.0 million in 1996.
This increase reflects an increase in revenues from book-length studies and
newsletter subscriptions, offset in part by a decrease in custom research.


     Cost of Services and Fulfillment.  Cost of services and fulfillment
increased 54.6% to $9.7 million in 1998 from $6.3 million in 1997. The increase
in this period was attributable to the overall growth of our business, in
particular the increased research staffing for new and existing research
practices. These expenses increased 33.5% to $6.3 million in 1997 from $4.7
million in 1996. The increase in this period was attributable to increased costs
for producing conferences and other direct products, and for increases in
research staffing. Gross margin increased to 34.6% in 1998 from 26.6% in 1997
and increased to 26.6% in 1997 from 25.0% in 1996 because the growth in our
client base and new business exceeded the growth in the cost of providing our
research services and conferences.


     Sales and Marketing.  Sales and marketing expenses increased 103.7% to $3.2
million in 1998 from $1.6 million in 1997. The increase in this period was
primarily attributable to an increased number of sales personnel and the
corresponding commission costs associated with increased revenues. Sales and
marketing expenses increased 202.7% to $1.6 million in 1997 from $514,000 in
1996. The expense increase in this period was primarily attributable to
increased personnel in the marketing area to support an increased direct mail
effort. As a percentage of total revenues, these expenses increased to 21.4% in
1998 from 18.3% in 1997 and increased to 18.3% in 1997 from 8.2% in 1996.

     General and Administrative.  General and administrative expenses increased
38.4% to $4.1 million in 1998 from $3.0 million in 1997 and 77.7% to $3.0
million in 1997 from $1.7 million in 1996. The increase in these periods was
primarily attributable to increased staffing for the finance, human resources
and operations areas, as well as increased expenses associated with basic office
operations, including rent, utilities, travel and printing. As a percentage of
total revenues, these expenses decreased to 27.6% in 1998 from 34.7% in 1997 and
increased to 34.7% in 1997 from 26.6% in 1996.

INCOME TAXES

     No provision or benefit for federal or state income taxes, actual or pro
forma, has been recorded for the net operating losses we incurred in the years
ended December 31, 1996, 1997 and 1998. In addition, no net operating losses
incurred in 1999 prior to the closing of this offering will be recorded on our
federal or state tax returns. Because our company was a limited liability
company for tax purposes during these periods, and will continue to be until the
closing of this offering, all taxable losses were, and will be, allocated to the
members for reporting on their income tax returns. As a result, we will not be
able to offset future taxable income, if any, against losses incurred prior to
the closing of this offering.

QUARTERLY RESULTS OF OPERATIONS DATA


     The following tables sets forth unaudited quarterly statement of operations
data for each of the six quarters ended June 30, 1999 and such data expressed as
a percentage of total revenues. We believe that we have prepared these data on
the same basis as our audited financial statements in this prospectus, and have
included all necessary adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of our results of operations for
these interim periods. You should read these interim financial data together
with our audited financial statements and the notes to those statements in this
prospectus. Our historical results of operations do not necessarily indicate the
results of operations we will achieve in the future, and our results of
operations for interim periods do not necessarily indicate the results of
operations for any future period. Our results of operations may fluctuate
significantly in the future as a result of a variety of factors, many of which
are beyond our control. See "Risk Factors--Our

                                       25

operating results may fluctuate in future periods which may cause volatility or
a decline in the price of our stock."

SEASONALITY


     Our conference revenues historically have been strongest during the third
quarter of the year, in which the largest number of our events are held. We also
have experienced a significant increase in SPS sales during the fourth quarter
of the year due primarily to the budget cycles of our SPS clients, the renewal
dates of existing SPS contracts and the effect of our annual sales quotas.

LIQUIDITY AND CAPITAL RESOURCES


     We have financed our operations since our organization on December 1, 1994
with a total of $4.2 million in member contributions. This includes $3.0 million
in private equity from Gartner Group in October 1997.



     Net cash provided by (used in) operating activities was $14,000 for the
year ended December 31, 1996, $(1.1) million for the year ended December 31,
1997, $(557,000) for the year ended December 31, 1998 and $3.2 million for the
six months ended June 30, 1999.



     Net cash used in investing activities was $257,000 in 1996, $232,000 in
1997, $838,000 in 1998 and $2.3 million for the six months ended June 30, 1999.
Investments were primarily in computer equipment, furniture and leasehold
improvements.



     Net cash provided by (used in) financing activities was $246,000 for the
year ended December 31, 1996, $2.9 million for the year ended December 31, 1997,
$(3,000) for the year ended December 31, 1998 and $375,000 for the six months
ended June 30, 1999. Cash provided by financing activities for the year ended
December 31, 1997 primarily resulted from the placement of private equity with
Gartner Group. In addition, during the six months ended June 30, 1999 two equity
members exercised unit investment options for $375,000.



     As of June 30, 1999, we had $1.6 million in cash and cash equivalents. We
have a $750,000 committed line of credit, secured by substantially all of our
assets, under which there were no outstanding balances as of June 30, 1999. We
have a commitment from our lender to increase this line to $3.0 million.



     We expect to spend approximately $4 million in 1999 and $7 million in 2000
on technology, including Web site enhancements, leasehold improvements,
expansion of operations and telecommunications upgrades. We anticipate that we
will continue to increase our capital expenditures and lease commitments
consistent with our anticipated growth in operations, infrastructure and
personnel. We also anticipate that we will continue to experience growth in our
operating expenses to support our revenue growth, including the continued
introduction of new practices and modules. While we have sufficient cash to fund
our current operations for the foreseeable future, the proceeds of this offering
are necessary to fund our anticipated growth. We believe that the net proceeds
of this offering, together with the unused line of credit, will be sufficient to
fund our operations for the next 2 years.


YEAR 2000 COMPLIANCE

     The Year 2000 problem is the result of computer programs being written
using two digits rather than four to identify a given year. Computer programs
that have time-sensitive software may interpret the date code "00" as the year
1900 rather than the year 2000. This could result in a disruption of operations
including a temporary inability to process transactions, send invoices or engage
in other normal business activities. We maintain a significant number of
computer software systems and operating systems across our entire organization
which are potentially subject to Year 2000 problems.

     Our Year 2000 concerns cover internal and external application and database
production software, internal and external production hardware, internal
infrastructure and external agents.


     Internal and external application and database production software includes
all software used either directly by our clients or indirectly in support of our
clients. We have upgraded or replaced all of these systems. All of the systems
are designed to pass Year 2000 compliance tests. System testing for Year 2000
compliance is anticipated to be completed by the end of the third quarter of
1999.



     Internal and external production hardware includes the hardware that we use
to directly host our Web site, our internal servers and network hardware and our
desktop systems. We have upgraded or replaced all hardware in direct support of
our Web site. We will upgrade or replace all internal servers, network hardware
and desktop systems by the end of the third quarter of 1999.


                                       27
<PAGE>   29


     Internal infrastructure consists of all hardware and software not described
above which is used in support of our internal staff. This includes all printers
and modems, the phone and voicemail systems and any common office automation
devices, including faxes and copiers. We upgraded the phone system in the second
quarter of 1999 and we will replace the voicemail system in the third quarter of
1999. We have upgraded or replaced all printers and modems. We will upgrade or
replace common office automation devices by the end of the third quarter of
1999.



     External agents includes all critical hardware, software and related
systems provided by third parties. Beginning in the second quarter of 1999, we
identified critical suppliers and equipment that we depend on for our day to day
business and surveyed these external vendors as to their Year 2000 compliance.
All of our critical external vendors have responded to our Year 2000 compliance
inquiries. 85% of these external vendors have indicated that they are Year 2000
compliant, 10% have indicated that they are in the process of upgrading or
replacing their systems and 5% have indicated that they are in the process of
assessing whether their systems are Year 2000 compliant. We keep a copy of all
third party Year 2000 compliance statements that we obtain.


     We expect that our employees will perform all significant work for the Year
2000 projects described above. We do not anticipate hiring any additional
employees nor do we anticipate incurring any significant consulting expenses for
the Year 2000 project. The cost of software tools and consulting expenses used
for detection of Year 2000 problems is not currently expected to exceed
$100,000.


     Contingency planning has not yet begun for all categories. We believe that
all critical systems are Year 2000 compliant as of September 1, 1999.



     The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, various normal business activities or
operations. Such failures could materially and adversely affect our results of
operations, liquidity and financial condition, and subject us to the risk of
litigation. Due to the general uncertainty inherent in the Year 2000 problem,
resulting in part from the uncertainty of the Year 2000 readiness of third-party
suppliers and customers, we are unable to determine at this time whether the
consequences of Year 2000 failures will have a material impact on our results of
operations, liquidity or financial condition.



     In addition, we cannot assure you that governmental agencies, utility
companies, internet access companies, third party service providers and others
outside our control will be Year 2000 compliant. The failure by those entities
to be Year 2000 compliant could result in a systematic failure beyond our
control, such as prolonged internet, telecommunications or electrical failure,
which could prevent us from providing our services or prevent users from
accessing our services.


RECENT ACCOUNTING PRONOUNCEMENTS

     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. SOP 98-1 will be effective for our
fiscal year ending December 31, 1999. The adoption of SOP 98-1 is not expected
to have a material impact on our financial statements.

     In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities" ("SOP 98-5"), which provides guidance on the financial reporting of
start-up costs and organization costs. It requires costs of start-up activities
and organization costs to be expensed as incurred. SOP 98-5 will be effective
for our fiscal year ending December 31, 1999. The adoption of SOP 98-5 is not
expected to have a material impact on our financial statements.

                                       28
<PAGE>   30

     In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 131, "Disclosures About Segments
of an Enterprise and Related Information" ("SFAS No. 131"), 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, and requires restatement of earlier periods presented. In the initial
year of application, comparative information for earlier years must be restated.
We have determined that we do not have any separately reportable business
segments.

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS No. 133"), 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, 2000. This statement is not expected to affect us as we currently
do not engage or plan to engage in derivative instruments or hedging activities.

MARKET OPPORTUNITY

  The Growth of Internet Commerce

     The Internet has emerged as a global medium that allows hundreds of
millions of people worldwide to obtain information, communicate and conduct
business electronically. The continued growth in Internet usage will be driven
by:

     - the large and growing number of personal computers installed in homes and
       offices;

     - easier, faster, more reliable and less expensive access to the Internet;

     - the availability of more and better content on the Internet;

     - improvements in network infrastructure; and

     - the increasing ability to access the Internet with devices like
       television and telephones.

     As the use of the Internet grows, businesses are increasing the breadth and
depth of their Internet products and services geared to consumers and other
businesses. Companies are also increasingly utilizing the Internet for functions
critical to their core business strategies and operations, such as sales and
marketing, customer service, supply chain management and overall project
coordination. As a result, numerous companies, including software development
firms, telecommunications and technology vendors and marketing and advertising
agencies, have developed products, services and technologies which support
consumers and businesses seeking to expand their use of the Internet or increase
their business efficiency.

     The unique interactive nature of the Internet has also led to its rapid
emergence as a convenient vehicle to buy and sell products and services.
Internet commerce can be fast, inexpensive and convenient, and a growing number
of users have used the Internet to trade securities, purchase goods and services
and pay bills. Retailers, advertisers and marketers have embraced the Internet
because it offers them the ability to:

     - reach broad, global audiences, thereby overcoming the limitations of
       brick-and-mortar businesses;

     - access new revenue streams;

     - target and cost-effectively market to consumers with specific sets of
       interests and desirable demographic characteristics; and

     - improve efficiencies in global corporate communications, supply chain
       management, technology implementation and overall operating expenses.


     We believe that the growth of the Internet, and the growth of Internet
commerce in particular, will continue to expand rapidly for the foreseeable
future both in the United States and abroad. A recent report by University of
Texas' Center for Research in Electronic Commerce estimated that the Internet
economy generated approximately $300 billion in U.S. revenue and was responsible
for 1.2 million jobs as of 1998. A recent study by the Organization for Economic
Cooperation and Development predicted that worldwide Internet commerce may grow
to $1 trillion by 2005. In addition, billion dollar markets are emerging on the
Internet for many different industry sectors.

     The graphs below illustrate our growth projections for various domestic
Internet markets. Our projections are based on a variety of research techniques,
including monthly tracking of online and non-online consumers, surveys of
leading executives at numerous Internet and technology companies, consumer
buying patterns in traditional retail markets and the historical development of
other markets and distribution channels.

  The Need for Timely, Unbiased and Affordable Advice

     The rapid growth of Internet commerce and the related increase of
innovative products, services and technologies have made it very difficult for
companies to keep pace with technological changes, to compete against new types
of companies and to generate research internally. Over the past few years,
numerous companies have been formed which focus solely on the delivery of
Internet access and online services, Internet commerce solutions and selling
products and services directly over the Internet. The emergence of these
Internet companies and the competitive challenges they pose have forced many
traditional companies, including financial services, telecommunications, media,
retail and consumer products companies, to make significant investments in
developing Internet-related businesses, services and strategies.


     We recently conducted an e-mail survey of 27 executives responsible for
their companies' Web initiatives. As part of the survey, we asked these
executives to indicate the extent to which their Web development budgets,
including staffing, hardware and software, have increased for 1999. 55% of the
27 executives indicated that their Web development budgets increased by more
than 75% for 1999, and 36% of the 27 executives indicated that their budgets
increased by more than 200% for 1999. Our research indicates that companies
today are spending between $500,000 for entry level marketing and branding Web
sites to more than $30 million for the most sophisticated Internet commerce
sites. In addition, many companies with no prior experience with Internet
commerce and Internet technology are increasingly attempting to understand the
rapid technological changes and to evaluate what steps they should take to
promote their businesses and compete effectively.

     There is tremendous uncertainty and anxiety among all of these types of
companies as to the future growth of Internet commerce and how it will affect
day-to-day decision-making and business development efforts. This uncertainty
and anxiety is not limited to technology personnel but is increasingly shared by
marketing and sales personnel, business development staff, senior executives and
boards of directors. Many companies do not have the technological knowledge or
the financial resources or personnel to research these issues and developments
internally. In addition, the abundance of conflicting information and
predictions regarding the growth of the Internet and the future marketplace are
very difficult for even experienced executives to decipher. Consequently, demand
is growing for timely and credible advice to assist companies in identifying
revenue models and success criteria, analyzing consumer adoption trends and
activity, developing effective sales and marketing operations, assessing market
trends and analyzing the competitive landscape and industry outlook. We expect
that demand for timely and credible advice will increase as use of the Internet
impacts new industries and expands into other geographic areas.

THE JUPITER SOLUTION

     We address the growing demand around the world for advisory research and
analysis on Internet commerce. All of our research is designed to help senior
executives at large and small companies in a wide range of industries make
difficult, complex and informed business decisions in the rapidly changing
Internet economy. Our research identifies revenue models and success criteria;
defines competitive landscapes; analyzes consumer demand for specific products
or Web sites; provides industry forecasts, markets projections and trend
analyses; and assesses the value of strategic partnerships and/or acquisitions.
Our Strategic Planning Services are provided on a subscription basis and
structured as a continuing information service for senior executives focused on
marketing, advertising, media and retail related to Internet commerce.

     Our solution provides the following key advantages:

     - OUR RESEARCH ENABLES SENIOR EXECUTIVES TO MAKE DIFFICULT AND COMPLEX
       BUSINESS DECISIONS.  Our research products and services enable companies
       to understand the rapid changes related to the growth of Internet
       commerce and to evaluate the steps they should take to promote their
       businesses and compete effectively. Our primary goal is to provide
       clients with prescriptive advice and practical business solutions. We
       support our research and analysis with extensive proprietary data,
       including market forecasts, executive surveys and surveys of Internet
       users and households. Our clients also have access to our research
       analysts to address specific business concerns, which enables them to
       make more informed business decisions and allows us to better understand
       and respond to their changing needs. We believe this interaction also
       allows us to sustain a high client retention rate and identify new
       research needs among our clients.


     - WE FOCUS SOLELY ON THE RAPIDLY EVOLVING INTERNET ECONOMY.  Our goal has
       been to position our company as the definitive proprietary resource for
       all Internet development efforts. Unlike many of our competitors which
       focus on information technology research, our research addresses the
       business and marketing strategies of companies grappling with Internet
       commerce. We typically cover the impact of new technology on traditional
       business models, the rate of return-on-investment and projections of
       consumer spending, not vendor selection or cost of implementation alone.
       As a result, our prospects and clients include chief executive officers
       and other senior executives, including sales, marketing, business
       development, operations and strategic planning executives.



     - OUR RESEARCH ANALYSTS ARE EXPERTS ON INTERNET COMMERCE.  Our analysts
       have years of relevant experience and are recruited from a variety of
       different industries, including management consulting and research firms,
       financial services, publishing, entertainment and advertising. Our
       analysts are frequently quoted in articles on the Internet and Internet
       commerce that appear in major newspapers, magazines and industry
       periodicals. In addition, our analysts are asked to speak at hundreds of
       non-Jupiter industry and corporate events. Because of their expertise,
       our analysts also have personal access to the leading decision makers in
       the Internet economy. We believe that the experience and prominence of
       our analysts allow us to provide original and prescriptive research which
       is unavailable elsewhere.


                                       32
<PAGE>   34


     - WE SUPPLEMENT OUR CORE PRACTICES WITH SPECIALIZED MARKET MODULES.  We
       supplement our seven core practices, which offer broad prescriptive
       advice relevant to all online ventures, with eleven market modules that
       target specific industries or geographic areas. By addressing market
       forecasts, competitive landscapes and business practices relating to
       specific industries and geographic areas, we are able to offer
       specialized insights to guide senior executives in their daily decision
       making.


     - WE PROVIDE DESKTOP ACCESS TO JUPITER RESEARCH THROUGH OUR WEB SITE.  Our
       Web site is an interactive platform that enables clients to access our
       products and services in a customized, easy-to-use manner. Our Web site
       allows users to search through our research and data libraries, send
       e-mails to client service representatives, access special content
       packages and register for conferences. In addition, our Web site offers
       analyst presentations and audio archives of analyst conference calls
       addressing the research reports that we publish.

OUR STRATEGY

     Our objective is to be the premier global research company focusing on
Internet commerce. Key elements of our business strategy include the following:


     - PROVIDING INNOVATIVE RESEARCH ON INTERNET COMMERCE.  We intend to
       continuously update, expand and refine our practices, market modules and
       data research capabilities to anticipate and meet the changing needs of
       business executives. We expect to add one practice and four market
       modules by the end of 1999, significantly expanding our research
       coverage. We also expect to continue to increase the number of our
       analysts and other research professionals.


     - INCREASING OUR CLIENT BASE IN THE UNITED STATES AND ABROAD.  We are
       committed to expanding our client base in the United States and abroad
       even further by expanding our research products and services, increasing
       our sales and marketing initiatives and personnel and focusing on client
       service. We intend to hire additional sales representatives who will be
       located in the targeted sales regions, as well as additional strategic
       account managers who specifically focus on sales to multinational
       companies. We also expect that the rapid changes in the Internet markets
       and our increased international focus will enable us to attract
       additional clients from new industries and geographic areas.

     - INCREASING THE LEVEL OF SALES TO EXISTING CLIENTS.  We are committed to
       increasing the total sales to our existing clients, as well as increasing
       the renewal rates for our SPS contracts. As Internet commerce continues
       to expand around the world, we expect that our existing clients will
       continue to need our research and advice and that they will purchase more
       of our research products. In addition, we intend to actively market all
       of our new practices and market modules to the executives already
       purchasing our products and services and to other executives at our
       current clients.

     - PURSUING INTERNATIONAL OPPORTUNITIES.  The growth of Internet commerce in
       foreign countries will present numerous opportunities for us to expand
       our international operations. We intend to add market modules and
       conferences that focus on specific geographic markets. We also expect to
       expand our London office which focuses on the European market, and we may
       open additional offices in foreign cities. We expect to enter into
       additional international distribution deals and strategic partnerships,
       and we will consider acquisitions of research firms to extend our
       international presence and research coverage.

     - CONTINUING TO STRENGTHEN THE JUPITER BRAND.  While we believe we have
       developed a strong brand name, we intend to engage in extensive public
       relations and marketing efforts to promote our business in the United
       States and abroad. These efforts will include an advertising campaign,
       continued enhancements to our Web site and an increase in the number of
       marketing events we sponsor for potential clients. We will also focus on
       expanding our press coverage and the exposure of our research analysts on
       television and at industry events.

     - INCREASING THE NUMBER OF CONFERENCES THAT WE PRODUCE.  We expect to
       expand the number of conferences that we produce, as well as update and
       refine our topics as the marketplace changes.

                                       33
<PAGE>   35

       We are currently exploring adding four additional conferences in the
       United States and abroad in 2000, including new events and regional
       versions of existing conferences. Our conferences offer excellent
       opportunities to showcase our research to potential clients, increase the
       public profile of our analysts, generate favorable press and otherwise
       promote the Jupiter brand.

     - ENHANCING OUR WEB DELIVERY PLATFORM.  We plan to continually upgrade our
       Web site to enable users to more easily access data, increase
       interactivity and enhance customization of delivery. In the fourth
       quarter of 1999, we plan to upgrade our Web site on a new platform which
       will enable clients to create more personalized views of their content
       and to search across all services more effectively. Our enhanced Web site
       will allow us to more effectively target specific research to clients,
       measure demand for our research and improve our customer service
       capabilities.

STRATEGIC PLANNING SERVICES

     Strategic Planning Services provides our clients with a wide range of
proprietary research, data and advisory analysis and is structured as a
continuous information service. We have designed our SPS research to enable
companies to make intelligent business decisions about Internet commerce and
consumer use of the Internet and related technologies. The core components of
our Strategic Planning Services are seven practices, which focus on issues vital
to all online ventures, and eleven market modules, which focus on discrete
industries and geographic areas. SPS contracts are renewable on an annual basis.
We also recently introduced our MindShare Senior Executive Program which is
targeted at chief executive officers and other senior executives. MindShare is
structured to combine forward-looking, broad strategic advice with focused
strategy sessions with our analysts. These research products and services
identify revenue models and success criteria, analyze consumer adoption trends
and provide advice, forecasts and industry trends for senior executives focused
on technology, content, advertising, entertainment and merchandising related to
Internet commerce.

     A key component of our Strategic Planning Services is access to our
research analysts for discussions and questions related to their published
reports. Our clients typically seek advice or have questions regarding new
business or marketing initiatives, best practices, new opportunities or
competitive threats, market forecasts and/or the value of mergers and strategic
partnerships. Clients submit inquiries to our dedicated client inquiry staff via
telephone, e-mail or our Web site. The client inquiry staff, which consists of
trained research professionals who are familiar with all of our products and
services, coordinates the responses and actively manages access to the analysts.


     The size of our SPS contracts varies depending on the number of practices
and market modules that are purchased and the number and type of users at the
client company. Some users have interactive access to our research and analysts
and receive hard copies of our research reports while other users only have the
ability to read research reports by accessing our Web site. Each Strategic
Planning Services contract includes at least one practice and passes to our
conferences. Additional practices, market modules and conference passes can be
added at a graduated cost. Participation in our MindShare program is purchased
separately for an annual fee.



     We have successfully expanded the number of clients for our Strategic
Planning Services, retained these clients when their contracts expire and
increased the level of sales to our clients. The number of SPS contracts has
increased from 145 on December 31, 1997, to 421 on December 31, 1998 and to 654
on June 30, 1999. In addition, 73% of the contracts that expired during the 12
months prior to June 30, 1999 were renewed. Approximately 95% of the contracts
that were renewed in the first six months of 1999 were for an equal or larger
dollar amount. Furthermore, the average size of our contracts with clients has
increased as well. Our average contract value was approximately $17,300 on
December 31, 1997, approximately $27,700 on December 31, 1998 and approximately
$33,850 on June 30, 1999. For our fifty largest clients, the average contract
value as of June 30, 1999 was $108,961.

- --------------------------------------------------------------------------------------------
</TABLE>


     We continually evaluate the market demand for additional practices and
expect to add one more practice by the end of 1999. We seek out and receive
input from our research analysts, the sales representatives that are in constant
contact with existing and potential clients and our marketing staff as to the
demand for specific research and our ability to provide coverage. We also
examine a variety of empirical data, including breadth of applicability,
uniqueness of the offering, competitive value and ease of communication.


     The SPS program is designed to provide business executives with the most
up-to-date research and analysis. We provide written reports on a regular basis
as well as ongoing access to our research analysts in order to answer specific
questions or clarify information relating to the practice topic. Specifically,
clients in any of the seven practices receive the following:

     - Monthly Analyst Reports.  Each monthly report examines a different
       industry, trend, product segment or business model relating to the
       specific practice.

     - Analyst Access.  Clients have access to Jupiter's research analysts for
       discussion, debate and additional advice. This service is available by
       phone or e-mail.

                                       36
<PAGE>   38

     - Weekly Analyst Notes.  Each week, clients receive a one-page briefing
       that analyzes topical issues related to the practice.

     - Digital Access.  Clients have password-only access to current research
       and a fully-searchable archive, which includes research, company profiles
       and slides from analyst presentations. Digital access to our Web site
       also includes a weekly "JupMail" e-mail that updates clients on recent
       research and upcoming events.

     - Monthly Teleconferences.  Each month, the research analysts from each of
       the practices conduct a "JupTel" telephone conference call that outlines
       the key findings from a recent monthly analyst report.

     - Conference Passes.  Clients are entitled to a specified number of passes
       to our conferences.

  MARKET MODULES

     In mid-1998, we began selling market modules which are designed to help
executives understand how the Internet is transforming the competitive landscape
and business practices in specific industries or geographic areas. As with our
practices, we provide subscribers with both written reports and access to our
research analysts for inquiries and insights. Specifically, subscribers to any
of the eleven market modules receive two semi-annual research reports, a
two-page monthly analyst note, access to our research analysts and digital
access to our Web site. The semi-annual research reports provide both an
overview of the key trends and business developments as well as comprehensive
reference materials, market forecasts, identification of key competitors and
information relating to strategic partnerships and acquisitions. The monthly
note highlights recent key trends or developments in the industry or country.

     Our market modules provide us with an excellent opportunity to market our
research to new clients and industries, as well as the ability to market new
products to our existing clients. The following is a list of the eleven market
modules in our SPS program, eight of which relate to specific industries and
three of which relate to specific geographic areas:

<TABLE>

             Television
               Travel
             Classifieds
</TABLE>

     As other industries and countries are affected by the growth of the
Internet, we anticipate expanding the number of our market modules which focus
on industries and geographic areas. Specifically, we expect to add four
additional geographic market modules by the end of 1999. As with our practices,
we examine on an ongoing basis the demand for new market modules.

  MINDSHARE SENIOR EXECUTIVE PROGRAM

     In February 1999, we launched our MindShare Senior Executive Program, which
is specifically targeted at chief executive officers and other senior executives
across all industries. This program combines forward-looking, broad strategic
advice with focused strategy sessions with our analysts. MindShare is designed
to enable these executives to better position and focus their companies,
prioritize business development opportunities, assess long-term competitive
threats and successfully integrate new technologies with Internet commerce.

                                       37
<PAGE>   39

     The cornerstone of our MindShare program is two half-day strategy sessions
with two research analysts per session at a location selected by the client. Our
MindShare clients also receive written reports that contain extensive
forward-looking research related to trends, changes and developments in the
Internet commerce marketplace. These quarterly reports are supplemented by
monthly briefings that focus on topical issues and major industry developments.
Furthermore, MindShare clients are invited to participate in our annual
executive forum, which is an invitation-only event targeted at a select group of
senior executive officers and technology leaders.

     In addition to providing significant value for our clients, MindShare helps
us to establish strong relationships with top executives at client companies. We
expect MindShare to enable us to bolster retention rates for SPS and to
strengthen our relationships with clients. We expect that the number of
MindShare clients will increase as we continue to expand the marketing of this
program and as the value of the products and services becomes more widely known.

JUPITER CONFERENCES

     We produce a wide range of conferences which provide comprehensive coverage
of issues relating to Internet commerce. These conferences offer senior
executives the opportunity to hear first-hand the insights of our analysts and
the leading decision makers in the Internet and technology industries. Our
events, which typically run for two to three days, provide an excellent
opportunity to showcase our research to current and potential clients, increase
the public profile of our research analysts, generate favorable press and
otherwise promote the Jupiter brand. Since over 75% of the attendees at our
conferences are not SPS clients, these events provide a unique opportunity to
promote our research products and services to potential customers. As a result,
our marketing staff and sales representatives attend each of our events and
conduct continuous promotional and direct sales efforts targeted at potential
clients. We believe that our events and the sales and marketing efforts at these
events have resulted in numerous SPS contracts.


     Our conferences, located in the United States and in Europe, are notable
for the senior level of attendees from all sectors of the online and media
industries. We produced eight conferences in 1997 and nine conferences in 1998.
We have scheduled ten conferences for calendar year 1999, six of which are large
events and four of which are small events. Paid attendance at our large events
typically ranges from 800-1,200 participants, while paid attendance at our small
events typically ranges from 400-600 participants. We also solicit sponsors and
exhibitors for each of our events. Exhibitors receive a booth at the conference
to promote their companies and are also listed in the conference program.
Sponsors receive prominent display of their corporate logos in the conference
program and the main meeting hall of the conference, and may host a reception
during the conference. We typically have approximately 50-75 sponsors and
exhibitors at our large events and 25 sponsors and exhibitors at our small
events.



     We have successfully increased attendance at our various conferences over
the past few years. For example, paid attendance at our seven conferences held
through August 1999 was 5,279, 95% above total paid attendance for all nine of
our conferences held in 1998. In addition, paid attendance at the six
conferences held so far in 1999 that were also held in 1998 has increased by
101%.

     As Internet commerce continues to grow, we anticipate that we will expand
the number of events that we produce as well as attract higher attendance at our
conferences. We also expect to devote more resources to promoting events outside
the United States or events with more of an international focus. Specifically,
in addition to the ten conferences described above, we plan to produce four
additional events during calendar year 2000, including conferences on health
care, European shopping and Latin America.

PUBLISHING AND CUSTOM RESEARCH

     We also provide other research products and services to clients, including
book-length research reports and customized research.

     We annually publish approximately fifteen book-length research studies that
are available for purchase through direct mail or on our Web site. Sales of
these studies are an important way to expose new companies and executives to our
research.

     We also perform customized, client-focused research projects relating to
Internet commerce on a limited basis. These projects allow our clients to take
advantage of the knowledge and experience of our research analysts and to
develop structured, detailed responses to specific issues relevant to their
business. Custom studies often form the basis to explore a new practice or
market module and, like our book-length studies, are an effective way to expose
new companies and executives to our research products and services.

CLIENTS


     Our client base has rapidly expanded since we launched SPS. In addition,
our client base has diversified from primarily technology and media companies to
include large and small companies in the Internet, media, telecommunications,
technology, financial services, consumer products, retail, travel and
professional services industries. Many of our clients have limited experience
with Internet commerce or operating an online business. The users of our
research products and services at our client companies hold diverse positions,
demonstrating the importance of Internet commerce to a company's overall
strategy and development. In addition to chief executive officers and
presidents, our users include marketing, business development, operations,
strategic planning and information technology executives.

     As of June 30, 1999, our clients included 78 of the Fortune 1000 companies,
22 of the AdWeek Top 100 Megabrands, 10 of the Fortune 50 commercial banks and
29 of Media Metrix's top 50 Web properties. Approximately 88% of these customers
are headquartered in the United States and the remainder are located primarily
in Europe. We expect that our client base will continue to expand as we
introduce new practices and market modules and increase our sales and marketing
initiatives. We also believe there is significant opportunity to increase our
penetration of large corporate clients. In addition, we expect the number of our
international clients to increase significantly as the use of the Internet grows
in other parts of the world and as we introduce additional products and services
targeted to international markets.

     To date, none of our clients have accounted for more than 2% of the total
annual revenues generated from SPS.


     As of June 30, 1999, we had 654 contracts for our Strategic Planning
Services. The following is a representative list of our larger clients:

RESEARCH METHODOLOGY

     Our research methodology enables us to deliver compelling, data-driven and
timely analysis across all seven practices and eleven market modules. Our
research products and services are generated by a growing team of research
professionals, including research analysts, an independent data research group
and a dedicated staff to handle client inquiries. These research professionals
are supported by in-house primary research tools and proprietary databases. In
addition, we have implemented a rigorous editorial and review process to ensure
that every report is accurate, well-written and useful to our clients.

     As of June 30, 1999, we employed a total of 74 research professionals,
including 38 analysts. The knowledge and experience of our research
professionals, particularly our analysts, are the crucial elements in our
ability to provide high-quality, timely and original research. Our analysts have
extensive industry

                                       40
<PAGE>   42

experience and varied backgrounds. We recruit them from a number of different
industries, including management consulting and research firms, financial
services, publishing, entertainment and advertising. We believe that the diverse
backgrounds and experiences of our analysts allow us to provide original and
prescriptive research and analysis which frequently challenges the conventional
wisdom and viewpoints promoted by others. We expect to significantly expand the
number of our research analysts as we grow the business and increase the number
of practices and market modules.

     The reports published by our analysts are supplemented with primary
research, data gathering, interviews and surveys of high-level industry
executives. To assist our analysts and their research activities, we have a
dedicated data research group that conducts discrete research and survey
projects, develops and maintains a series of econometric forecast models and
works with the analysts to provide a statistical foundation for their findings.

     Our analysts and our data research group have access to significant
proprietary data, including the following:

     - HOUSEHOLD SURVEYS.  Twice a year, we field a broad benchmarking survey of
       a large representative sample of United States households, including
       those that are not yet online. Data from these consumer surveys are
       incorporated into the body of our proprietary research products.

     - ONLINE USER SURVEYS.  Each month, we conduct focused, in-depth surveys of
       thousands of online consumers. As with the household surveys described
       above, the data from these surveys are incorporated into the body of our
       proprietary research products.

     - MARKET FORECASTS.  Our analysts forecast the future of various online
       markets to help guide clients' strategies and investments. Complementing
       our qualitative predictions, these forecasts measure the expected growth
       of many industry indicators and market sectors.

     - EXECUTIVE SURVEYS.  We conduct phone and written surveys with top
       industry executives to understand their strategies, attitudes and
       intentions. These data provide our research analysts with systematic and
       comprehensive insight into those leaders whose actions shape the online
       marketplace.


     We design the large-scale household and online user surveys described above
which are conducted through our arrangement with NFO Worldwide, one of the
largest worldwide research organizations. In exchange for these surveys, we pay
NFO Worldwide a fee and provide complementary sponsorships, exhibit booths and
speaking opportunities at many of our conferences. While NFO maintains the
panels, all of the questions and surveys that we prepare and provide NFO, as
well as all of the findings and results from these survey panels, remain our
proprietary data.


     All of our research products are subject to a stringent editorial and
review process to ensure the highest quality. We maintain consistency among the
formats of our research reports across the practices and market modules so as to
ensure clarity and readability by all of our clients. Each research topic is
first subject to a series of discussions and meetings to define the scope of the
topic, assess the relevance and importance of the research and highlight key
themes and questions. Prior to publication, each research report is subject to
ongoing review and comment from other analysts and research management.

SALES AND MARKETING

     We sell and market our research products and services primarily through our
direct sales force, which was comprised of 40 sales representatives as of June
30, 1999. This represents an increase from four sales representatives at the end
of 1997 and 21 sales representatives at the end of 1998. As with our research
analysts, our sales representatives have diverse backgrounds and experience in a
number of different industries. In addition, we have been very successful at
retaining our sales representatives. Of the 36 sales representatives hired
between January 1, 1998 and June 30, 1999, 35 are still employed with us.

     Our sales representatives currently consist of strategic account managers,
who are each responsible for 20 to 30 multinational companies, and geographic
account managers, who are each responsible for specific
                                       41
<PAGE>   43

territories. Our strategic account managers are focused on selling a broad array
of products and services across a global enterprise. Unlike many of our direct
and indirect competitors, we try, to the extent possible, to locate our sales
representatives in the geographic territories that they cover. Specifically, as
of June 30, 1999, 34 of our 40 sales representatives were located in the
territories that they cover. We believe that this allows us to develop stronger
relationships with our current and potential clients and to better understand
the changing needs of our clients. We have implemented a training program for
all of our new sales representatives and believe that this program has been
effective in enabling our sales representatives to quickly and effectively
solicit new clients. Sales representatives receive a base salary and are
eligible for commissions based on new business and renewals.

     We expect to significantly increase the number of our sales representatives
as we grow the business and increase our international operations. In addition
to our sales representatives, we use independent sales distributors to sell our
products and services in Australia and Israel. We are currently exploring
similar distribution arrangements in other countries and may enter into
additional agreements of this nature in the future.

     We have developed a number of strategies and programs to build awareness of
the Jupiter name and to position the company as the definitive research resource
for Internet commerce. We employ an active press relations team, which responds
to hundreds of press inquiries on a weekly basis, and an in-house
promotions/advertising staff, which is responsible for developing sales
literature and direct mail campaigns and managing our advertising efforts. Our
analysts are frequently quoted in articles on the Internet and e-commerce that
appear in major newspapers, magazines and industry periodicals. In addition, we
actively encourage our research analysts to speak at non-Jupiter industry and
corporate events in order to enhance our reputation and promote our diverse
products. For example, in the first six months of 1999, our research analysts
appeared at approximately 80 non-Jupiter events, conferences and forums around
the world, and we intend to increase this activity in the future. We estimate
that our analysts addressed approximately 36,000 people at these functions. We
also host numerous breakfast forums around the world which are targeted at
potential customers and designed to enhance our visibility and reputation.
During the first six months of 1999, we hosted a total of 38 forums which
collectively had over 2,300 guests. We also devote significant resources to
promoting our numerous research products and services to the thousands of
individuals attending our conferences. Lastly, we use our Web site as a tool to
market the Jupiter name and expose potential customers to our products.

COMPETITION

     We believe that the primary competitive factors determining success in our
markets include the quality and timeliness of our research and analysis, our
ability to offer products and services that meet the changing needs of our
customers, the prices we charge for our various research products and general
economic conditions. We believe that we compete favorably with respect to each
of these factors. In addition, we believe that we distinguish ourselves from our
competitors as a result of the depth and breadth of our Strategic Planning
Services, the extent to which we provide access to our research analysts, the
quality of our research analysts and sales representatives and the primary
research tools and proprietary databases that we have developed internally.


     Our principal current competitor is Forrester Research. Recently Gartner
Group announced its intention to compete directly in providing research products
related to Internet commerce. A number of other companies compete with us in
providing research and analysis related to a specific industry or geographic
area. In addition, our competitors include information technology research
firms, business consulting and accounting firms, electronic and print publishing
companies and equity analysts employed by financial services companies.


     We expect competition to increase because of the business opportunities
presented by the growth of Internet commerce around the world. Competition may
also intensify as a result of industry consolidation, because the markets in
which we operate face few substantial barriers to entry or because some of our

                                       42
<PAGE>   44

competitors may provide additional or complementary services, such as consulting
services. Our current and potential competitors include many companies that have
substantially greater financial, information gathering and marketing resources
than we have. This may allow them to devote greater resources than we can to the
promotion of their brand and to the development and sale of their products and
services. We cannot assure you that we will be able to compete successfully
against current and future competitors.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS


     To protect our rights to our intellectual property, we rely on a
combination of trademark and copyright law, trade secret protections and
confidentiality agreements and other contractual arrangements with our employees
and third parties. We have registered the Jupiter, Jupiter Communications and
Internet Business Report marks in the United States, and we have pending
trademark applications for certain other trademarks in the United States,
including SPS. We also have pending trademark applications for the Jupiter and
Jupiter Communications marks in various foreign jurisdictions. We provide our
proprietary research products to hundreds of different companies throughout the
world, including some companies that compete with us in some manner. As a
result, the protective steps we have taken may be inadequate to protect our
intellectual property and to deter misappropriation of the original research and
analysis that we develop. We also may be unable to detect the unauthorized use
of, or take appropriate steps to enforce, our intellectual property rights.
Moreover, effective trademark, copyright and trade secret protection may not be
available in every country in which we offer our research products and services
to the extent available in the United States.


     Our failure to adequately protect our intellectual property, either in the
United States or abroad, could harm the Jupiter brand or our trademarks, devalue
our proprietary research and analysis and affect our ability to compete
effectively. Defending our intellectual property rights could result in the
expenditure of significant financial and managerial resources, which could harm
our financial results.

     Furthermore, although we believe that our proprietary rights do not
infringe on the intellectual property rights of others, other parties may assert
claims against us that we have misappropriated a trade secret or infringed a
patent, copyright, trademark or other proprietary right belonging to them. Any
infringement or related claims, even if not meritorious, could be costly and
time consuming to litigate, may distract management from other tasks of
operating the business and may result in the loss of significant rights and the
loss of our ability to operate our business.

EMPLOYEES


     As of June 30, 1999, we had 194 full-time employees, including 40 sales
representatives and 74 research staff, of which 38 were analysts. Our
compensation policy promotes employee ownership, and we believe that this policy
contributes to the high retention rates of our research analysts and sales
representatives. Specifically, as of June 30, 1999, approximately 93% of our
employees, including all of our research analysts and sales representatives,
owned options to purchase our securities.


     All of our research analysts and sales representatives, as well as all of
our executive officers, have entered into agreements that prohibit them from
being employed by a competitive company for a period of one year following their
termination of employment with us. None of our employees are represented under
collective bargaining agreements. We believe that our relations with our
employees are good.

FACILITIES

     Our headquarters are located in a leased facility in New York, New York,
consisting of approximately 27,700 square feet of office space. We also lease
office space in London, England. We are in negotiations to lease additional
office space in New York, New York and in San Francisco, California.

LEGAL PROCEEDINGS

     We are not a party to any material legal proceedings.

COMPOSITION OF THE BOARD

     Upon the completion of this offering, we intend to file an amended and
restated certificate of incorporation pursuant to which our board of directors
will be divided into three classes, each of whose members will serve for a
staggered three-year term. Upon the expiration of the term of a class of
directors, directors in that class will be elected for three-year terms at the
annual meeting of stockholders in the year in which their term expires. Our
board of directors has resolved that                will be a Class I Director
whose term expires at the 2000 annual meeting of stockholders,
will be a Class II Director whose term expires at the 2001 annual meeting of
stockholders and                and                will be Class III Directors
whose terms expire at the 2002 annual meeting of stockholders. With respect to
each class, a director's term will be subject to the election and
disqualification of their successors, or their earlier death, resignation or
removal.

BOARD COMMITTEES

     The Audit Committee of the board of directors will be established prior to
the closing of this offering and will review, act on and report to the board of
directors with respect to various auditing and accounting matters, including the
recommendation of Jupiter's auditors, the scope of the annual audits, fees to be

accounting practices of Jupiter.

     The Compensation Committee of the board of directors will be established
prior to the closing of this offering and will recommend, review and oversee the
salaries, benefits and stock option plans for Jupiter's employees, consultants,
directors and other individuals compensated by Jupiter. The Compensation
Committee will also administer Jupiter's compensation plans.

DIRECTOR COMPENSATION

     Other than reimbursing directors for customary and reasonable expenses of
attending board of directors or committee meetings, Jupiter does not currently
compensate its directors. Under our 1999 Stock Incentive Plan, each individual
who first joins the Jupiter board after the effective date of this offering as a
non-employee board member will automatically receive a grant of an option on
that date to purchase        shares of common stock at the time of his or her
commencement of board service. In addition, on the date of each annual
stockholders' meeting beginning in 2000, each non-employee member of the board
of directors who is to continue to serve as a non-employee board member will
automatically be granted an option to purchase        shares of common stock.
Please see "--1999 Stock Incentive Plan."

(1) Each option represents the right to purchase one share of common stock. The
    options shown in these columns, which were originally granted pursuant to
    Jupiter Communications, LLC's 1997 Option Plan, vest at a rate of 25% after
    one year from the date of grant and 6.25% each quarter thereafter.

(2) Amounts represent hypothetical gains that could be achieved for the
    respective options if exercised at the end of the option term. The 5% and
    10% assumed annual rates of compounded stock price appreciation are mandated
    by rules of the Securities and Exchange Commission and do not represent our
    estimate or projection of our future common stock prices. These amounts
    represent certain assumed rates of appreciation in the value of our common
    stock from the fair market value on the date of grant. Actual gains, if any,
    on stock option exercise depend on the future performance of the common
    stock. The amounts reflected in the table may not necessarily be achieved.

    of $3.00 per share, less the applicable exercise price, multiplied by the

1997 OPTION PLAN


     Jupiter Communications, LLC adopted the 1997 Option Plan in June 1997. A
total of 2,750,000 units have been reserved for issuance under this plan. As of
August 31, 1999, options to purchase a total of 2,523,731 units were outstanding
under the 1997 Option Plan. Upon the merger of Jupiter Communications, LLC with
and into Jupiter Communications, Inc., the plan and each outstanding option will
be assumed by Jupiter Communications, Inc. and no further options will be
granted under this plan.


     Each option has a maximum term of seven years. The exercise price of each
option must be paid in cash. In the event of an acquisition of Jupiter, each
option may, at our discretion, be accelerated or assumed by the successor
corporation.

1999 STOCK INCENTIVE PLAN

     The 1999 Stock Incentive Plan will be adopted by the board of directors and
approved by our stockholders prior to the date of this offering. The 1999 Stock
Incentive Plan will be administered by our compensation committee.


     5,000,000 shares of common stock have been authorized for issuance under
the 1999 Stock Incentive Plan. However, in no event may one participant in the
1999 Stock Incentive Plan receive option grants or direct stock issuances for
more than      shares in the aggregate per calendar year.


     The 1999 Stock Incentive Plan will be divided into five separate programs:

     - the discretionary option grant program under which eligible individuals
       in the employ of Jupiter may be granted options to purchase shares of
       common stock at an exercise price determined by the plan administrator;

     - the stock issuance program under which eligible individuals may be issued
       shares of common stock directly, through the purchase of these shares at
       a price determined by the plan administrator or as a bonus tied to the
       performance of services;

     - the salary investment option grant program which may, at the plan
       administrator's discretion, be activated for one or more calendar years
       and, if so activated, will allow executive officers and other highly
       compensated employees the opportunity to use a portion of their base
       salary to acquire special below market stock option grants;

     - the automatic option grant program under which option grants will
       automatically be made at periodic intervals to eligible non-employee
       board members 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;
       and

     - the director fee option grant program under which non-employee board
       members may be given the opportunity to use a portion of any retainer fee
       otherwise payable to them in cash for the year to acquire special below
       market stock option grants.

     The 1999 Stock Incentive Plan will include the following features:

     - The exercise price for any options granted under the plan may be paid in
       cash or in shares of our 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.

     - The compensation committee will have the authority to cancel outstanding
       options under the discretionary option grant program 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
       common stock on the new grant date.

     - Stock appreciation rights may be issued under the discretionary option
       grant program. Such rights will provide the holders with the election to
       surrender their outstanding options for an appreciation distribution from
       Jupiter equal to the fair market value of the vested shares of common
       stock

                                       49
<PAGE>   51

       subject to the surrendered option less the exercise price payable for
       those shares. Jupiter may make the payment in cash or in shares of common
       stock.

     The 1999 Stock Incentive Plan will include change in control provisions
that may result in the accelerated vesting of outstanding option grants and
stock issuances:

     - In the event that Jupiter is acquired by merger or asset sale or a
       board-approved sale of more than 50% of Jupiter stock by its
       stockholders, each outstanding option under the discretionary option
       grant program that is not assumed or continued by the successor
       corporation will immediately become exercisable for all the option
       shares, and all unvested shares will immediately vest, except to the
       extent our repurchase rights with respect to those shares are to be
       assigned to the successor corporation.

     - The plan administrator may grant options which vest immediately upon an
       acquisition of Jupiter or upon a hostile change of control or upon the
       individual's termination of service following an acquisition that results
       in a change in control.


     The board will be able to amend or modify the 1999 Stock Incentive Plan at
any time, subject to any required stockholder approval. The 1999 Stock Incentive
Plan will terminate no later than October   , 2009.


1999 EMPLOYEE STOCK PURCHASE PLAN


     The 1999 Employee Stock Purchase Plan will be adopted by the board of
directors and approved by the stockholders prior to the date of this offering.
The plan will become effective immediately upon the execution of the
underwriting agreement for this offering. The plan is designed to allow eligible
employees of Jupiter and its participating subsidiaries to purchase shares of
our common stock, at semi-annual intervals, through their periodic payroll
deductions. A total of 500,000 shares of common stock may be issued under the
plan.


     The plan will have a series of successive offering periods, each with a
maximum duration of 24 months. However, the initial offering period will begin
on the day the underwriting agreement is executed in connection with this
offering and will end on the last business day in October 2001. The next
offering period will begin on the first business day in November 2001, and
subsequent offering periods will be set by our compensation committee.


     A participant may contribute up to 15% of his or her cash earnings through
payroll deductions and the accumulated payroll deductions will be applied to the
purchase of shares on the participant's behalf on each semi-annual purchase date
(the last business day in April and October of each year). The purchase price
per share will be 85% of the lower of the fair market value of our common stock
on the participant's entry date into the offering period or the fair market
value on the semi-annual purchase date. The first purchase date will occur on
the last business day in April 2000. In no event, however, may any participant
purchase more than           shares, nor may all participants in the aggregate
purchase more than                shares on any one semi-annual purchase date.
Should the fair market value of the common stock on any semi-annual purchase
date be less than the fair market value on the first day of the offering period,
then the current offering period will automatically end and a new offering
period will begin, based on the lower fair market value.


     The board will be able to amend or modify the plan at any time. The plan
will terminate no later than the last business day in October 2009.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

     The following description of our common stock and preferred stock and the
relevant provisions of our amended and restated certificate of incorporation and
amended and restated bylaws as will be in effect upon the closing of this
offering are summaries thereof and are qualified by reference to our amended and
restated certificate of incorporation and the amended and restated bylaws,
copies of which have been filed with the Securities and Exchange Commission as
exhibits to our registration statement, of which this prospectus forms a part.


     Upon the closing of this offering, our authorized capital stock will
consist of 100,000,000 shares of common stock, par value $0.001 per share, and
5,000,000 shares of preferred stock, par value $0.001 per share.


COMMON STOCK


     Upon the closing of this offering, and giving effect to the issuance of
3,125,000 shares of common stock in this offering and the merger of Jupiter
Communications, LLC with and into Jupiter Communications, Inc., there will be
14,160,335 shares of common stock outstanding. Holders of common stock are
entitled to one vote for each share held on all matters submitted to a vote of
stockholders and do not have cumulative voting rights. Accordingly, 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 ratably those dividends, if any, as may be
declared by the board of directors out of funds legally available therefor,
subject to any preferential dividend rights of any outstanding preferred stock.
Upon the liquidation, dissolution or winding up of Jupiter, the holders of
common stock are entitled to receive ratably the net assets of Jupiter available
after the payment of all debts and other liabilities and subject to the prior
rights of any outstanding preferred stock. Holders of the common stock have no
preemptive, subscription, redemption or conversion rights. The outstanding
shares of common stock are, and the shares offered by us in this offering will
be, when issued in consideration for payment thereof, fully paid and
nonassessable. 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 which we may designate and issue in the
future. Upon the closing of this offering, there will be no shares of preferred
stock outstanding.


PREFERRED STOCK

     Upon the closing of this offering, there will be no shares of preferred
stock 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 and to fix or alter the designations, preferences, rights and any
qualifications, limitations or restrictions of the shares of each series
thereof, including the dividend rights, dividend rates, conversion rights,
voting rights, terms of redemption, including sinking fund provisions,
redemption price or prices, liquidation preferences and the number of shares
constituting any series or designation of series. We have no present plans to
issue any shares of preferred stock. See "--Anti-Takeover Effects of Various
Provisions of Delaware Law and Jupiter's Certificate of Incorporation and
Bylaws."

OPTIONS


     Options to purchase a total of 7,750,000 shares of common stock may be
granted under the 1997 Option Plan and the 1999 Stock Incentive Plan. As of
August 31, 1999, there were outstanding options to purchase a total of 2,523,731
shares of common stock, of which options to purchase approximately 735,932 will
be exercisable upon the closing of this offering. In addition, there were
outstanding options to purchase a total of 174,992 shares of common stock upon
the exercise of non-plan options, of which options to purchase 166,992 shares
are currently exercisable. Since we intend 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


                                       53
<PAGE>   55


these options will be immediately available for sale in the public market,
subject to the terms of any lock-up agreements entered into with the
underwriters. See "Management--1997 Option Plan," "Management--1999 Stock
Incentive Plan" and "Shares Eligible for Future Sale."


REGISTRATION RIGHTS


     Pursuant to the terms of a registration rights agreement, after the closing
of this offering the holders of 10,956,335 shares of common stock will be
entitled to piggyback registration rights with respect to the registration of
their shares under the Securities Act, subject to various limitations. These
registration rights are subject to specific conditions and limitations, among
them the right of the underwriters of an offering to limit the number of shares
of common stock held by security holders with registration rights to be included
in a registration. Registration of any shares of the shares of common stock held
by security holders with registration rights would result in shares becoming
freely tradable without restriction under the Securities Act immediately upon
effectiveness of such registration.


ANTI-TAKEOVER EFFECTS OF PROVISIONS OF DELAWARE LAW AND JUPITER'S CERTIFICATE OF
INCORPORATION AND BYLAWS

     We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. Subject to some exceptions, Section 203 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 interested stockholder. Subject to
various exceptions, an "interested stockholder" is a person who, together with
affiliates and associates, owns, or within three years did own, 15% or more of
the 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 Jupiter and, accordingly, may discourage attempts to acquire Jupiter.

     In addition, various provisions of our amended and restated certificate of
incorporation and our amended and restated bylaws, which provisions will be in
effect upon the closing of the offering and are summarized 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.  Our amended and restated certificate of
incorporation 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 this removal with its own
nominees.

     STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS.  Our amended and
restated certificate of incorporation provides that stockholders may not take
action by written consent, but only at duly called annual or special meetings of
stockholders. The amended and restated certificate of incorporation further
provides that special meetings of stockholders of Jupiter may be called only by
the chairman of the board of directors, the chief executive officer or a
majority of the board of directors.

     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 various 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, corporate acquisitions and employee benefit plans. The existence of
authorized but unissued shares of common stock and preferred stock could make
more difficult or discourage an attempt to obtain control of us by means of a
proxy contest, tender offer, merger or otherwise.

                                       54
<PAGE>   56

     The Delaware General Corporation Law provides generally that the
affirmative vote of a majority of the shares entitled to vote on any matter is
required to amend a corporation's certificate of incorporation or bylaws, unless
a corporation's certificate of incorporation or bylaws, as the case may be,
requires a greater percentage.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is American Stock
Transfer & Trust Company, New York, New York.

                        SHARES ELIGIBLE FOR FUTURE SALE


     Sales of substantial amounts of our common stock in the public market could
adversely affect prevailing market prices of our common stock. Furthermore,
since no shares will be available for sale shortly after this offering because
of various contractual and legal restrictions on resale described below, sales
of substantial amounts of common stock in the public market after these
restrictions lapse could adversely affect the prevailing market price and our
ability to raise equity capital in the future.



     Upon the closing of this offering, we will have outstanding an aggregate of
14,160,335 shares of our common stock, assuming no exercise of the underwriters'
over-allotment option and no exercise of outstanding options. Of these shares,
all shares sold in this offering will be freely tradeable without restriction or
further registration under the Securities Act unless such shares are purchased
by "affiliates" as that term is defined in Rule 144 under the Securities Act.
This leaves 11,035,335 shares eligible for sale in the public market as follows:

LOCK-UP AGREEMENTS



     Stockholders holding an aggregate of                shares of common stock
and substantially all of our option holders have signed lock-up agreements under
which they agreed not to transfer or dispose of, directly or indirectly, any
shares of our common stock or any securities convertible into or exercisable or
exchangeable for shares of our common stock for 180 days after the date of this
prospectus. Transfers can be made sooner with the prior written consent of
Donaldson, Lufkin & Jenrette Securities Corporation, in the case of some
transfers to affiliates, or if made as a bona fide gift.



     Our largest stockholder, Gartner Group, has not signed a similar lock-up
agreement. The Company believes, however, that Gartner Group may be deemed an
"affiliate" as that term is defined in Rule 144 and therefore may not sell any
shares held by it until 90 days from the date of this prospectus and thereafter
may sell shares subject only to the Rule 144 volume limitations discussed below.
Gartner Group has advised us that it does not believe it will be an "affiliate"
following the closing of this offering. In the event Gartner Group is deemed not
to be an "affiliate" after this offering, it will be able to sell as many as
3,515,624 shares of our common stock in the public market without regard to
volume limitations beginning 90 days after the date of this prospectus, which
could adversely affect the price of our stock.


RULE 144


     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of 1% of
the number of shares of common stock then outstanding, which will equal
approximately                shares immediately after the offering, or the
average weekly trading volume of the common stock on the Nasdaq National Market
during the four calendar weeks preceding the filing of a notice on Form 144 with
respect to such sale. Sales under Rule 144 are also subject to specific
manner-of-sale provisions, notice requirements and the availability of current
public information about us.


                                       56
<PAGE>   58

RULE 144(k)

     Under Rule 144(k), a person who is not one of our affiliates at any time
during the 90 days preceding a sale and who has beneficially owned the shares
proposed to be sold for at least two years, including the holding period of any
prior owner other than an affiliate, is entitled to sell such shares without
complying with the manner of sale, public information, volume limitation or
notice provisions of Rule 144. Therefore, unless otherwise restricted, "144(k)"
shares may be sold immediately upon completion of this offering.

RULE 701


     In general, under Rule 701 of the Securities Act as currently in effect,
each of our employees, consultants or advisors who purchases shares from us in
connection with a compensatory stock plan or other written agreement is eligible
to resell such shares 90 days after the effective date of this offering in
reliance on Rule 144, but without compliance with various restrictions,
including the holding period, contained in Rule 144.


REGISTRATION RIGHTS


     After this offering, the holders of at least 10,956,335 shares of our
common stock will be entitled to various rights with respect to the registration
of those shares under the Securities Act. See "Description of Capital
Stock -- Registration Rights." After such registration, these shares of our
common stock become freely tradeable without restriction under the Securities
Act. These sales could have a material adverse effect on the trading price of
our common stock.


STOCK PLANS


     Immediately after this offering, we intend to file a registration statement
under the Securities Act covering 8,424,492 shares of common stock reserved for
issuance under our 1997 Option Plan, our 1999 Stock Incentive Plan, our Employee
Stock Purchase Plan and the shares reserved for issuance upon exercise of
outstanding non-plan options. We expect this registration statement to be filed
and to become effective as soon as practicable after the effective date of this
offering.



     As of August 31, 1999, options to purchase 2,698,223 shares of common stock
were issued and outstanding. All of these shares will be eligible for sale in
the public market from time to time, subject to vesting provisions, Rule 144
volume limitations applicable to our affiliates and, in the case of some
options, the expiration of lock-up agreements.

     The underwriting agreement provides that the obligations of the several
underwriters to purchase and accept delivery of the shares included in this
offering are subject to approval of specific legal matters by their counsel and
to various other conditions. The underwriters are obligated to purchase and
accept delivery of all the shares, other than those covered by the
over-allotment option described below, if they purchase any of the shares.



     The underwriters propose to initially offer some of the shares directly to
the public at the public offering price set forth on the cover page of this
prospectus and some of the shares to various dealers at the public offering
price less a concession not in excess of $     per share. The underwriters may
allow, and such dealers may re-allow, a concession not in excess of $     per
share on sales to other dealers. After the initial offering of the shares to the
public, the representatives may change the public offering price and such
concessions. The underwriters do not intend to confirm sales to any accounts
over which they exercise discretionary authority. An electronic prospectus is
available on the Web site maintained by DLJdirect Inc.


     The following table shows the underwriting fees to be paid to the
underwriters by us in connection with this offering. These amounts are shown
assuming both no exercise and full exercise of the underwriters' over-allotment
option described below.

     We will pay the offering expenses, estimated to be approximately $1.1
million.



     We have granted to the underwriters an option, exercisable for 30 days
after the date of this prospectus, to purchase up to 468,750 additional shares
at the public offering price less the underwriting fees. The underwriters may
exercise such option solely to cover over-allotments, if any, made in connection
with this offering. To the extent that the underwriters exercise such option,
each underwriter will become obligated, subject to various conditions, to
purchase a number of additional shares approximately proportionate to that
underwriter's initial purchase commitment.



     We have agreed to indemnify the underwriters against various civil
liabilities, including liabilities under the Securities Act of 1933, or to
contribute to payments that the underwriters may be required to make in respect
of any of those liabilities.


     We, all of our executive officers and directors, stockholders holding an
aggregate of           shares of common stock and substantially all of our
option holders have agreed, for a period of 180 days from the date of this
prospectus, not to, without the prior written consent of Donaldson, Lufkin &
Jenrette Securities Corporation: offer, pledge, sell, contract to sell, sell any

any option or contract to sell, grant any option, right or warrant to purchase
or otherwise transfer or dispose of, directly or indirectly, any shares of our
common stock or any securities convertible into or exercisable or exchangeable
for our common stock; or enter into any swap or other arrangement that transfers
all or a portion of the economic consequences associated with the ownership of
any common stock, regardless of whether any of these transactions is to be
settled by the delivery of common stock, or such other securities, in cash or
otherwise. In addition, during this 180-day period, we have agreed not to file
any registration statement with respect to, and each of our executive officers,
directors, stockholders and option holders has agreed not to make any demand
for, or exercise any right with respect to, the registration of any shares of
common stock or any securities convertible into or exercisable or exchangeable

Jenrette Securities Corporation.

     Outside the United States, neither we nor the underwriters have taken any
action that would permit a public offering of the shares of common stock
included in this offering in any jurisdiction that requires action for that
purpose. The shares included in this offering may not be offered or sold,
directly or indirectly, nor may this prospectus or any other offering material
or advertisement in connection with the offer and sale of any of these shares be
distributed or published in any jurisdiction, except under circumstances that
will result in compliance with the applicable rules and regulations of that
jurisdiction. We advise persons who receive this prospectus to inform themselves
about and to observe any restrictions relating to the offering of the common
stock and the distribution of this prospectus. This prospectus is not an offer
to sell or a solicitation of an offer to buy any shares of our common stock
included in this offering in any jurisdiction where that would not be permitted
or legal.


     In connection with this offering, some underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
common stock. Specifically, the underwriters may overallot this offering,
creating a syndicate short position. The underwriters may bid for and purchase
shares of our common stock in the open market to cover syndicate short positions
or to stabilize the price of the common stock. The underwriting syndicate may
reclaim selling concessions if the syndicate repurchases previously distributed
common stock in syndicate covering transactions, in stabilizing transactions or
in some other way or if Donaldson, Lufkin & Jenrette Securities Corporation
receives a report that indicates clients of such syndicate members have
"flipped" the common stock. These activities may stabilize or maintain the
market price of the common stock above independent market levels. The

     - our prospects for future earnings;

     - the recent market prices of securities of generally comparable companies;

     - the general condition of the securities markets at the time of the

     At our request, the underwriters have reserved for sale at the initial
public offering price up to 7% of the shares of common stock to be sold in this
offering for sale to our employees, friends and persons having business
relationships with us. Our employees who purchase more than 100 shares of common
stock in the initial public offering will sign lock-up agreements in connection
with those shares. To the extent these persons purchase the reserved shares, the
number of shares available for sale to the general public will be reduced. The
underwriters will offer any reserved shares not so purchased on the same basis
as the other shares offered by this prospectus.

                          INDEPENDENT AUDITORS' REPORT

The Board of Members and Members
Jupiter Communications, LLC:

     We have audited the accompanying balance sheets of Jupiter Communications,
LLC as of December 31, 1997 and 1998, and the related statements of operations
and members' equity (deficiency), and cash flows for each of the years in the
three-year period ended December 31, 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 Jupiter Communications, LLC
as of December 31, 1997 and 1998, and the results of its operations and its cash
flows for each of the years in the three-year period ended December 31, 1998, in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

                  DECEMBER 31, 1997 AND 1998 AND JUNE 30, 1999

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1998 IS UNAUDITED)

(1) ORGANIZATION

     Jupiter Communications, LLC ("Jupiter" or the "Company") was organized in
New York on December 1, 1994. Jupiter is a new media research firm that helps
companies make intelligent business decisions about consumer interactivity. The
Company's information services encompass Strategic Planning Services,
conferences, newsletters, book-length studies, and custom research reports and
provide clients and customers with focused research and strategic planning
support as they develop interactive products and services.

(2) SIGNIFICANT ACCOUNTING POLICIES


  (a) UNAUDITED INTERIM FINANCIAL INFORMATION AND UNAUDITED PRO FORMA BALANCE
SHEET



     The interim financial statements of the Company for the six months ended
June 30, 1998 and 1999 included herein have been prepared by the Company,
without audit, pursuant to the rules and regulations of the SEC. Certain
information and note disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to such rules and regulations relating to interim
financial statements.



     In the opinion of management, the accompanying unaudited interim financial
statements reflect all adjustments, consisting only of normal recurring
adjustments, necessary to present fairly the financial position of the Company
at June 30, 1999 and the results of its operations and its cash flows for the
six months ended June 30, 1998 and 1999.



     The accompanying pro forma balance sheet as of June 30, 1999 gives effect
to (i) the Company's pending reorganization from a limited liability company to
a corporation (see Note 2(f)) as though the reorganization had occurred as of
June 30, 1999, and (ii) the sale of 3,125,000 shares of common stock related to
the Company's proposed initial public offering ("IPO") (see Note 14 regarding
the proposed IPO) at an assumed initial public offering price of $16.00 per
share (less estimated underwriting discounts and offering expenses) as though
the IPO had occurred as of June 30, 1999.


  (b) CASH AND CASH EQUIVALENTS


     Cash equivalents of $1,613,015, $211,681 and $1,470,060 at December 31,
1997, December 31, 1998 and June 30, 1999, respectively, consist of a money
market account with an initial term of less than three months. For purposes of
the statements of cash flows, the Company considers all highly liquid debt
instruments with original maturities of three months or less to be cash
equivalents.


  (c) PREPAID EXPENSES AND OTHER ASSETS

     Prepaid expenses and other assets primarily consist of prepaid Strategic
Planning Services commissions and prepaid conference costs.

  (d) PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation is provided by the
straight-line method over the estimated useful lives of the respective assets,
which range from three to five years. Leasehold improvements are amortized on a
straight-line basis over the shorter of the lease term or their estimated useful
life. Additions and major improvements are capitalized, whereas the cost of
maintenance and repairs is charged to operations as incurred.

                                       F-7
<PAGE>   70
                          JUPITER COMMUNICATIONS, LLC

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

                  DECEMBER 31, 1997 AND 1998 AND JUNE 30, 1999

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1998 IS UNAUDITED)

  (e) INTANGIBLE ASSETS

     Intangible assets are stated at cost and are amortized over their useful
lives. The net book value of intangible assets is periodically evaluated by
management as to the realizability by the Company with any permanent impairment
in such value charged to operations in the year so determined.

  (f) INCOME TAXES


     Until completion of the proposed IPO (see Note 14 regarding the proposed
IPO), the Company will remain a New York limited liability company. Accordingly,
income or loss attributed to the Company's operations prior to the closing of
the IPO will be allocated to its members to be reported on their personal tax
returns. As a result, Jupiter will not be able to offset future taxable income,
if any, against losses incurred prior to the closing of the IPO.


     Upon completion of the proposed IPO, the Company's LLC status will be
terminated as a result of the Company reorganizing to a "C" corporation for tax
purposes. Effective on this date, income taxes will be accounted for under the
asset and liability method. Under this method, deferred tax assets and
liabilities are recognized for 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 the tax change occurs. Valuation
allowances are established, when necessary, to reduce deferred tax assets to the
amount expected to be realized.

  (g) REVENUE AND COMMISSION EXPENSE RECOGNITION

     Strategic Planning Services revenues are deferred and then reflected
proportionally in operations over the term of the service period, which is
generally up to one year. Conference revenues are reflected in operations when
the conference occurs. Newsletter subscriptions are deferred and then reflected
proportionally in operations over the term of the subscription, which is
generally up to one year. Book-length studies and custom research are reflected
in operations when the product is shipped.

     Deferred revenue is composed of prepaid Strategic Planning Services fees to
be earned in the future over the term of the service period, prepaid conference
sponsorship/exhibition fees to be earned from conferences held after the balance
sheet date, and prepaid newsletter subscriptions to be earned in the future over
the term of the subscriptions.

     The Company records prepaid commissions related to Strategic Planning
Services upon the signing of the contract and amortizes this corresponding
prepaid commission expense over the contract period in which the related
revenues are earned and amortized to income.


  (h) CONCENTRATION OF RISK



     The Company's customers are concentrated in the United States. The Company
performs ongoing credit evaluations of its customers' financial condition and
generally does not require collateral and establishes an allowance for doubtful
accounts based upon factors surrounding the credit risk of customers, historical
trends and other information. To date, such losses have been within management's
expectations.


                                       F-8
<PAGE>   71
                          JUPITER COMMUNICATIONS, LLC

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

                  DECEMBER 31, 1997 AND 1998 AND JUNE 30, 1999

         (ALL INFORMATION SUBSEQUENT TO DECEMBER 31, 1998 IS UNAUDITED)


     For each of the years in the three-year period ended December 31, 1998, no
customer accounted for more than 10% of revenues generated by the Company, or of
accounts receivable at December 31, 1998, 1997 and 1996.



  (i) USE OF ESTIMATES


     The accompanying financial statements are prepared in accordance with U.S.
generally accepted accounting principles (GAAP). In preparing financial
statements in conformity with GAAP, management is required to make estimates and
assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements and revenue and expenses during the reporting period. Actual results
could differ from those estimates.


  (j) FAIR VALUE OF FINANCIAL INSTRUMENTS


     The carrying amount of cash and cash equivalents, accounts payable and
accrued expenses approximated fair value because of the relatively short
maturity of these instruments.


  (k) STOCK-BASED COMPENSATION


     The Company adopted Statement of Financial Accounting Standards (SFAS) No.
123, "Accounting for Stock-Based Compensation," which permits entities to
recognize the fair value of all stock-based awards on the date of grant as
expense over the vesting period. Alternatively, SFAS No. 123 also allows
entities to continue to apply the provisions of APB Opinion No. 25, "Accounting
for Stock Issued to Employees," and provide pro forma net loss disclosures for
employee unit option grants made as if the fair value-based method defined in
SFAS No. 123 had been applied.

     Under APB Opinion No. 25, compensation expenses would be recorded on the
date of grant only if the current market price of the underlying units exceeded
the exercise price. The Company has elected to apply the provisions of APB
Opinion No. 25 and provide the pro forma disclosure provisions of SFAS No. 123.


  (l) PRO FORMA BASIC AND DILUTED NET LOSS PER COMMON SHARE



     Pro forma basic and diluted net loss per common share is computed by
dividing net loss by the pro forma weighted average number of shares of common
stock. Pro forma weighted average number of shares of common stock gives effect
to the Company's pending reorganization from a limited liability company to a
corporation (see Note 2(f)). Pro forma weighted average number of shares of
common stock does not include any common stock equivalents because inclusion of
common stock equivalents would have been anti-dilutive.



  (m) IMPAIRMENT OF LONG-LIVED ASSETS TO BE DISPOSED OF


     The Company applies the provisions of SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,"
which requires that long-lived assets and certain identifiable intangibles be
reviewed 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
an asset to future net cash flows expected to be generated by the asset. If such
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. Assets to be disposed of are reported at
the lower of the carrying amount or fair value less costs to sell. Adoption of
this Statement did not have a material impact on the Company's financial
position, results of operations or liquidity.


  (n) RECENT ACCOUNTING PRONOUNCEMENTS


     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. SOP 98-1 will be effective for the
Company's fiscal year ending December 31, 1999. The adoption of SOP 98-1 is not
expected to have a material impact on the Company's financial statements.

     In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities" ("SOP 98-5") which provides guidance on the financial reporting of
start-up costs and organization costs. It requires costs of start-up activities
and organization costs to be expensed as incurred. SOP 98-5 will be effective
for the Company's fiscal year ending December 31, 1999. The adoption of SOP 98-5
is not expected to have a material impact on the Company's financial statements.

     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, and requires
restatement of earlier periods presented. In the initial year of application,
comparative information for earlier years must be restated. The Company has
determined that it does not have any separately reportable business segments.

     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, 2000. This
statement is not expected to affect the Company as it currently does not engage
or plan to engage in derivative instruments or hedging activities.

(6) INVESTMENT IN METHODFIVE LLC



     Jupiter has an investment in Methodfive LLC ("Methodfive"), formerly the
Myriad Agency, LLC, a Web site design and consulting company. For the years
ended December 31, 1997 and 1998, Methodfive experienced a net loss from
operations and the Company recorded its share of the loss in the accompanying
statements of operations and members' equity (deficiency). Jupiter's cumulative
interest in Methodfive as of December 31, 1997 and 1998 was approximately 17.4%
and has been accounted for under the equity method.



     As of June 30, 1999 the Company has written down its investment as a result
of the current financial position and recurring losses of Methodfive. The
Company has no future funding responsibilities with respect to Methodfive and
has a 17.4% passive interest.


(7) MEMBERS' EQUITY

     The Company has three classes of members' equity: Class A, Class B and
Class C. Class A, Class B and Class C equity members own respectively 33.5%,
29.2% and 37.3% of the Company, as of December 31, 1998. All equity members have
substantially the same rights and privileges, except that Class B equity members
do not participate in the day-to-day management of the business. Class C equity
members, as well, do not participate in the day-to-day management of the
business; however, certain actions, as defined in the operating agreement,
require the consent of Class C equity members.

     During October 1997, Gartner Group, Inc. ("acquiror") purchased 3,515,624
Class C units of the Company for $8.0 million from both the Company and existing
members. The Company amended its operating agreement to allow current members to
sell all or part of their units to the acquiror. During 1997, existing members
sold 2,197,265 units for $5.0 million, and 1,318,359 units were purchased from
the Company for $3.0 million and recorded as capital contributions by the
Company, less $254,098 in offering costs. Class A and Class B units sold by
existing members to the acquiror automatically converted to Class C units upon
transfer on a one-for-one basis to the acquiror. Three members sold 100% of
their units to the acquiror. In addition, during 1997 capital contributions of
$250,273 were made by existing Class A and B equity members. During 1998, an
existing member sold 333,333 units for $1.25 million to the acquiror. After
completion of the transactions, the acquiror owned 37.3% of all outstanding
units as of December 31, 1998, and had two seats on the board of members.

     Profits and losses are shared by all members based on their respective
percentage ownership interests. No member shall be liable for any debts of the
Company or be required to contribute any additional capital related to deficits
incurred.

(8) OPTIONS

     During 1997, the Company established the 1997 Employee Unit Option Plan
(the "Plan"). Under the Plan, 1,590,000 Class B units shall be available for
grant. On March 1, 1999, the equity members authorized an increase in the number
of units reserved for issuance under the Plan from 1,590,000 to 2,500,000 (see
Note 14). Unit options may be granted to key employees of the Company upon
selection by the managing members. The exercise price of a unit option shall be
equal to the established fair market value of the unit at the time of grant, in
accordance with the provisions of the Plan. These options vest ratably over a
four-year period.

     All unit options have a fixed term determinable by the managing members,
but no option shall be exercisable more than seven years after the date of
grant. Option exercisability is subject to the terms and conditions as
determined by the managing members.

     Unit option activity under the Plan is as follows:

     The fair value of each unit option granted to employees during 1998 is
estimated using the Black-Scholes Option Pricing Model with the following
assumptions: dividend yield 0%, 1998 risk-free interest rate 6% and an expected
life of four years. As permitted under the provision of SFAS No. 123, and based
on the historical lack of a public market for the Company's units, no factor for
volatility has been reflected in the unit option pricing calculation.

     The Company applies APB Opinion No. 25 in accounting for its Plan and,
accordingly, no compensation cost has been recognized for its unit options in
the accompanying financial statements.

     Rent expense for the years ended December 31, 1996, 1997 and 1998 was
$111,433, $335,063 and $303,061, respectively.

     During April 1998, the Company entered into a seven-year operating lease
agreement for office space in London. The lease agreement calls for monthly
payments with no scheduled increase in succeeding periods.


     During January 1999, the Company terminated its existing New York operating
lease agreements that were due to expire in May 2000 and December 2001 and
signed a new five-year operating lease agreement with the same landlord. The new
lease agreement covers the same office space as the terminated lease agreement
as well as additional office space. In connection with this lease agreement, the
Company received two months of free rent. The agreement also calls for scheduled
increases in succeeding periods. As such, the Company records rent expense on a
straight-line basis. The future payments related to this new lease agreement are
reflected in the above schedule, and the deferred rent balance as of June 30,
1999 reflects the impact of the new lease.

(14) SUBSEQUENT EVENTS (UNAUDITED)

  a) INITIAL PUBLIC OFFERING

     In July 1999, the Class A equity members authorized the filing of a
registration statement with the Securities and Exchange Commission ("SEC") that
would permit the Company to sell shares of its common stock in connection with
the proposed IPO.

     Upon the completion of the proposed IPO, the Company will be reorganized
from a limited liability company (LLC) to a corporation, which will be treated
as a "C" corporation for tax purposes. All of the members of the LLC will
exchange their respective member interests in the LLC for shares of common stock
in the corporation.

     After the IPO, the members no longer retain the rights granted to them as
part of the Company's Operating Agreement, other than piggyback registration
rights and, with respect to the Class C equity member, limited indemnification
rights.

  b) LINE OF CREDIT

     During March 1999, the Company entered into an agreement for a line of
credit of $750,000 with the Silicon Valley Bank. Any unpaid balance is payable
on demand and bears an interest rate of prime plus 1%. All of the Company's
assets were listed as collateral in the event of default. No amounts were
outstanding as of March 31, 1999.

     During June 1999, the Company received a commitment to increase this line
of credit to $3.0 million. Any unpaid balance is payable on demand and bears an
interest rate of prime plus 1 1/2%. In the event that the Company raises an
additional $3 million of equity financing, the interest rate on the $3 million
line of credit will be reduced to prime plus  3/4%.

  c) ADVERTISING COMMITMENTS

     In 1999, the Company entered into certain advertising contracts and has
future advertising commitments with a publishing company in the amount of
approximately $500,000.

number of units reserved for issuance under the Plan from 2,500,000 to
2,750,000.

  e) CLASS B (NON-VOTING) UNITS

     In July 1999, the equity members authorized the Company to issue Class B
(Non-Voting) units which shall provide Jupiter with, among other things,
flexibility in the issuance of units in connection with mergers, acquisitions
and/or similar transactions and in the exercise of options. Holders of Class B
(Non-Voting) units shall have the same rights and privileges as holders of Class
B units, except for certain specified rights.

  f) ACQUISITION OF INTELLIGENCE SE AB

     In July 1999, the Company acquired all of the stock of Intelligence SE AB,
a Swedish research company, in exchange for 137,000 Class B (Non-Voting) units
at an aggregate value of $808,000.

existing equity members.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The registrant's certificate of incorporation in effect as of the date
hereof, and the registrant's amended and restated certificate of incorporation
to be in effect upon the closing of this offering (collectively, the
"Certificate") provide 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 non-monetary 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 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 intends to obtain liability insurance for its officers and directors
prior to the closing of this offering.

     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 DGCL
and provides that the registrant shall 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 such 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
                                      II-1
<PAGE>   82

and amounts paid in settlement actually and reasonably incurred by such person
in connection with such 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

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES

     Within the last three years, the registrant has sold and issued the
following securities:

     Units.  Between November 1996 and February 1997, the registrant sold
approximately 11% of the company to Kurt Abrahamson, Joshua A. Weinreich and
Narain Gehani, for an aggregate purchase price of $500,000. In addition, the
registrant granted these individuals options to purchase an additional 667,968
units at a weighted average exercise price of $0.75. In October 1997, Gartner
Group purchased 1,318,359 Class C units from Jupiter Communications, LLC for a
total of $3.0 million.

     Upon the closing of this offering, Jupiter Communications, LLC will merge
with and into Jupiter Communications, Inc. In connection with this merger, all
membership units in Jupiter Communications, LLC will be exchanged for shares of
common stock of Jupiter Communications, Inc. The sales of the above securities
were deemed to be exempt from registration pursuant to Section 4(2) of the
Securities Act of 1933, as amended.

     Options.  The registrant has from time to time granted options to purchase
units in Jupiter Communications, LLC in reliance upon exemptions from
registration pursuant to either Section 4(2) of the Securities Act of 1933, as
amended, or Rule 701 promulgated under the Securities Act of 1933, as amended.
The following table sets forth certain information regarding such grants:

ITEM 17.  UNDERTAKINGS

     The undersigned registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the underwriters 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
such indemnification is against public policy as expressed in the Securities
Act, and is, therefore, unenforceable. In the event that a claim for
indemnification against such 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 such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such 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

                                      II-3
<PAGE>   84

     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 the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

ninetieth (90th) day nor earlier than the close of business on the one hundred
twentieth (120th) day prior to the first anniversary of the date of the
preceding year's annual meeting; provided, however, that if either the date of
the annual meeting is more than thirty (30) days before or more than seventy
(70) days after such anniversary date, notice by the stockholder to be timely
must be so delivered not earlier than the close of business on the one hundred
twentieth (120th) day prior to such annual meeting and not later than the close
of business on the later of the ninetieth (90th) 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

                                       3

case pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (the "Exchange Act") and Rule 14a-11 thereunder
(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, the text of
the proposal or business (including the text of any resolutions proposed for
consideration and in the event that such business includes a proposal to amend
the By-laws of the Corporation, the language of the proposed amendment), 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, (ii) the class and number of
shares of capital stock of the Corporation which are owned beneficially and of
record by such stockholder and such beneficial owner, (iii) a representation
that the stockholder is a holder of record of stock of the Corporation entitled
to vote at such meeting and intends to appear in person or by proxy at the
meeting to propose such business or nomination, and (iv) a representation
whether the stockholder or the beneficial owner, if any, intends or is part of a
group which intends (a) to deliver a proxy statement and/or form of proxy to
holders of at least the percentage of the Corporation's outstanding capital
stock required to approve or adopt the proposal or elect the nominee and/or (b)
otherwise to solicit proxies from stockholders in support of such proposal or
nomination. The Corporation may require any proposed nominee to furnish such
other information as it may reasonably require to determine the eligibility of
such proposed nominee to serve as a director of the Corporation.

                    3. Notwithstanding anything in the second sentence of
paragraph (a)(2) of this Section 12 to the contrary, in the event that the
number of directors to be elected to 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 one hundred (100) days prior to the first anniversary of the
preceding year's annual meeting, a stockholder's notice required by this Section
12 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 notice provided for in
this Section 12 is delivered to the Secretary of the Corporation, who is
entitled to vote at the meeting and upon such election, who complies with the
notice procedures set forth in this Section 12. 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 entitled to vote in
such election of directors 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

                                       4
<PAGE>   5
required by paragraph (A)(2) of this Section 12 shall be delivered to the
Secretary at the principal executive offices of the Corporation not earlier than
the close of business on the one hundred twentieth (120) day prior to such
special meeting and not later than the later of (x) the close of business of the
ninetieth (90th) day prior to such special meeting or (y) the close of business
of the tenth (10th) day following the day on which public announcement is first
made of the date of such special meeting and of the nominees proposed by the
Board of Directors to be elected at such meeting. In no event shall the public
announcement of an adjournment or postponement of a special meeting commence a
new time period (or extend any time period) for the giving of a stockholder's
notice as described above.

                  C. General.

                    1. Only such persons who are nominated in accordance with
the procedures set forth in this Section 12 shall be eligible to be elected at
an annual or special meeting of stockholders of the Corporation 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 12. 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 (a) 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 12 (including
whether the stockholder or beneficial owner, if any, on whose behalf the
nomination or proposal is made solicited (or is part of a group which solicited)
or did not so solicit, as the case may be, proxies in support of such
stockholder's nominee or proposal in compliance with such stockholder's
representation as required by clause (A)(2)(c)(iv) of this Section 12) and (b)
if any proposed nomination or business was not made or proposed in compliance
with this Section 12, to declare that such nomination shall be disregarded or
that such proposed business shall not be transacted.

                    2. For purposes of this Section 12, "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
Sections 13, 14 and 15(d) of the Exchange Act.

                    3. Notwithstanding the foregoing provisions of this Section
12, 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 12 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 pursuant
to any applicable provisions of the Certificate of Incorporation.

                  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 12.

                  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 stockholders at the annual meeting of the stockholders, except as provided
in Section 2 of this Article. The Board shall be divided into three classes as
nearly equal in number as possible. The members of each class shall be elected
for a term of three years and until their successors are elected and qualified.
The Board of Directors shall be classified in accordance with the provisions of
the Corporation's Certificate of Incorporation. Directors need not be
stockholders.

                  Section 2. Vacancies and newly created directorships resulting
from any increase in the authorized number of directors may be filled by 66.67%
of the directors then in office, though less than a quorum, or by a sole
remaining director, and the directors so chosen shall hold office until the next
annual election at which such director's class is 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 by the Certificate of Incorporation or by these By-Laws directed or
required to be exercised or done by the stockholders.

Delaware.

                  Section 5. Regular meetings of the Board of Directors may be
held without notice at such time and at such place as shall from time to time be
determined by the Board. Members of the Board of Directors may participate in
regular or special meetings by means of conference telephone or similar
communications equipment by which all persons participating in the meeting can
hear each other. Such participation shall constitute presence in person.

                  Section 6. Special meetings of the Board may be called by the

shall be called by the president or secretary or chairman of the board in like
manner and on like notice on the written request of two directors unless the

and on like notice on the written request of the sole director.

                  Section 7. At all meetings of the Board a majority of the
directors fixed by Section 1 shall constitute a quorum for the transaction of
business and the act of a majority of the directors present at any meeting at
which there is a quorum shall be the act of the Board of Directors, except as
may be otherwise specifically provided by statute or by the Certificate of
Incorporation. If a quorum shall not be present at any meeting of the Board of
Directors, the directors present thereat may adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum
shall be present.

                  Section 8. Unless otherwise restricted by the Certificate of
Incorporation of these By-Laws, any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee thereof may be taken
without a meeting, if all members of the Board or committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the Board or committee.

                  Section 9. Unless otherwise restricted by the Certificate of
Incorporation 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 of one or more of the directors of the Corporation. The
Board may designate one or more directors as alternate members of any committee,
who may replace any 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.

                  Any such committee, to the extent provided in the resolution
of the Board of Directors, shall have and may exercise all the powers and
authority of the Board of Directors in the management of the business and
affairs of the Corporation, and may authorize the seal of the Corporation to be
affixed to all papers which may require it; but no such committee shall have the
power or authority in reference to amending the Certificate of Incorporation,
adopting an agreement of merger or consolidation, recommending to the
stockholders the sale, lease or
                                       7

exchange of all or substantially all of the Corporation's property and
assets, recommending to the stockholders a dissolution of the Corporation or a
revocation of a dissolution, or amending the By-Laws of the Corporation; and,
unless the resolution or the Certificate of Incorporation expressly so provide,
no such committee shall have the power or authority to declare a dividend or to
authorize the issuance of stock. Such committee or committees shall have such
name or names as may be determined from time to time by resolution adopted by
the Board of Directors.

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


         Compensation of Directors

                  Section 12. Unless otherwise restricted by the Certificate of
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.


         Removal of Directors

                  Section 13. Any director or the entire Board of Directors may

                  Section 1. Whenever, under the provisions of the statutes or
of the Certificate of Incorporation or of these By-Laws, notice is required to
be given to any director or stockholder, it shall not be construed to mean
personal notice, but such notice may be given in writing, by mail, addressed to
such director or stockholder, at his address as it appears on the records of the
Corporation, with postage thereon prepaid, and such notice shall be deemed to be
given at the time when the same shall be deposited in the United States mail.
Notice to directors may also be given by telecopy.


                  Section 2. Whenever any notice is required to be given under

entitled to said notice, whether before or after the time stated therein, shall
be deemed equivalent thereto.

each class of stock or series thereof and the qualification, limitations or

without a meeting unless expressly disallowed by the Certificate of
Incorporation, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in

date of such meeting, nor more than sixty (60) days prior to any other action. A
determination of stockholders of record entitled to notice of or to vote at a

express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                  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

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

                  Section 3. All checks or demands for money and notes of the
Corporation shall be signed by such officer or officers or such other person or
persons as the Board of Directors may from time to time designate.

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 more of the directors or officers are directors or officers, or have a
financial interest, shall be void or voidable solely for this reason, or solely
because such director or officer is present at or participates in the meeting of
the Board of Directors or a committee of the Board of Directors which authorizes
the contract or transaction or solely because his, her or their votes are
counted for such purpose, if:


                    (1) The material facts as to his or her relationship or
interest and as to the contract or transaction are disclosed or are known to the
Board of Directors or the committee, and the Board or committee in good faith
authorizes the contract or transaction by the affirmative vote of a majority of
the disinterested directors, even though the disinterested directors be less
than a quorum;

                    (2) The material facts as to his or her relationship or
interest and as to the contract or transaction are disclosed or are known to the
stockholders entitled to vote thereon, and the contract or transaction is
specifically approved in good faith by vote of the stockholders; or

<PAGE>   15
                    (3) The contract or transaction is fair as to the
Corporation as of the time it is authorized, approved or ratified, by the Board
of Directors, a committee of the Board of Directors, or the stockholders. Common
or interested directors may be counted in determining the presence of a quorum
at a meeting of the Board of Directors or of a committee which authorizes the
contract or transaction.

by the stockholders of the Corporation by vote 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 (provided
that notice of such proposed repeal, alteration, amendment or rescission is
included in the notice of such meeting). In addition, in accordance with the
Corporation's Certificate of Incorporation, the Board of Directors may repeal,
alter, amend or rescind these By-Laws by vote of 66.67% of the Board of
Directors.

                      Form S-1 (File No. 333-84175)


Ladies and Gentlemen:


                  We have acted as counsel to Jupiter Communications, Inc., a
Delaware corporation (the "Company"), in connection with the proposed issuance
and sale by the Company of up to 3,125,000 shares of the Company's Common Stock
(the "Shares") pursuant to the Company's Registration Statement on Form S-1 (the
"Registration Statement") filed with the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the "Act").


                  This opinion is being furnished in accordance with the
requirements of Item 16(a) of Form S-1.

                  We have reviewed the Company's charter documents and the
corporate proceedings taken by the Company in connection with the issuance and
sale of the Shares. Based on such review, we are of the opinion that the Shares
have been duly authorized, and if, as and when issued in accordance with the
Registration Statement and the related prospectus (as amended and supplemented
through the date of issuance) will be legally issued, fully paid and
nonassessable.

                  We consent to the filing of this opinion letter as Exhibit 5.1
to the Registration Statement and to the reference to this firm under the
caption "Legal Matters" in the prospectus which is part of the Registration
Statement. In giving this consent, we do not thereby admit that we are within
the category of persons whose consent is required under Section 7 of the Act,
the rules and regulations of the Securities and Exchange Commission promulgated
thereunder, or Item 509 of Regulation S-K.

                          JUPITER COMMUNICATIONS, INC.

                          REGISTRATION RIGHTS AGREEMENT

         This Registration Rights Agreement (this "Agreement") is made as of
September __, 1999 by and among Jupiter Communications, Inc., a Delaware
corporation (the "Company"), and the individuals and entities named as
Stockholders on the signature pages hereof (the "Stockholders").

         WHEREAS, the Stockholders previously entered into that certain Third
Amended and Restated Operating Agreement of Jupiter Communications, LLC, dated
as of October 22, 1997 (the "Operating Agreement"), which provides for certain
registration rights to be granted to the Stockholders;


         WHEREAS, in connection with the Company's proposed initial public
offering, the Company will effect a merger (the "Merger") pursuant to which
Jupiter Communications, LLC will be merged with and into the Company;


         WHEREAS, in connection with the Merger, the Stockholders will receive
shares (the "Shares") of the common stock, par value $0.001 per share (the
"Common Stock"), of the Company in exchange for the units of Jupiter
Communications, LLC currently owned by the Stockholders; and

         WHEREAS, the Company now wishes to grant the Stockholders certain
registration rights with respect to the Shares.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
promises set forth herein, the Company and the Stockholders agree as follows:

         1. EFFECTIVE DATE. This Agreement shall become effective upon the
consummation of the Merger.

         2. REGISTRATION RIGHTS.

                  (a) In the event that the Company contemplates a Public
Offering (as defined below), the Company shall so notify the Stockholders in
writing of its intention to do so at least thirty (30) days prior to the filing
of the registration statement related to such Public Offering. Each Stockholder
shall give written notice to the Company, within twenty (20) days of receipt of
such notice from the Company, of such Stockholder's desire to have any of its
Registrable Securities (as defined below) of the Company included in such
registration statement and may, subject to the provisions of this Section 2,
have its Registrable Securities so included. The Company shall file any required
amendments of or supplements to any registration statement related to such
Public Offering and otherwise use its best efforts to insure that such
registration statement remains in effect under the Securities Act of 1933, as
amended, until the earlier of the sale of all of the Registrable Securities
included in the registration or the expiration of one hundred twenty (120) days
from the effective date thereof.


                                       1
<PAGE>   2
                  For purposes of this Section 2, a "Public Offering" shall mean
a public offering by the Company of any class or classes of its securities under
the Securities Act of 1933, as amended, provided that the aggregate gross
proceeds of the offering of such securities (before reduction by underwriting
commissions and other expenses of sale) exceed $15,000,000.

                  (b) "Registrable Securities" shall mean shares of Common Stock
outstanding as of the date hereof or any equity securities into which such
shares of Common Stock may be converted or exchanged and which are included in
the registration statement being filed.

                  (c) If the Public Offering of which the Company gives notice
is for a registered public offering involving an underwriting, the Company shall
so advise the Stockholders as a part of the written notice given pursuant to
Section 2(a). In such event the right of a Stockholder to registration pursuant
to Section 2(a) shall be conditioned upon the Stockholder's participation in
such underwriting and the inclusion of the Stockholder's Registrable Securities
in the underwriting to the extent provided herein. If the managing underwriter
in such underwritten offering shall advise the Company that, due to marketing
limitations or other industry-accepted criteria, it declines to include a
portion or all of the securities requested by Stockholders and other persons
with piggyback registration rights to be included in the registration statement,
then all or a portion of the Registrable Securities requested for inclusion in
the registration statement (and offering, if applicable) may be excluded from
such registration statement (and offering, if applicable), in which case the
number of securities included in the registration statement on behalf of persons
other than the Company shall be allocated among the Stockholders and other
holders of registration rights in proportion to the respective numbers of
securities entitled to registration rights held by the Stockholders and other
holders requesting registration. In such event the Company shall give the
Stockholders prompt notice of the number of Registrable Securities excluded.
Should a Stockholder propose to distribute the Company's securities through such
underwriting, then the Stockholder shall (together with the Company and any
others distributing their securities through such underwriting) enter into an
underwriting agreement and related documents in customary form with the managing
underwriter selected for such underwriting by the Company (or by any other
person or entity who has demanded such registration), which may include, among
other things, indemnification, lock-up and expense sharing provisions.

                  (d) The Company shall have the right to terminate or withdraw
any registration initiated by it under this Section 2 prior to the effectiveness
of such registration whether or not any Stockholder or Stockholders have elected
to include securities in such registration.

                  (e) The Stockholders will cooperate with the Company in all
respects in connection with such registration statement, including, but not
limited to, timely supplying all information reasonably requested by the Company
and executing and returning all documents reasonably requested in connection
with the registration and sale of the Registrable Securities. It shall be a
condition to the Company's obligations to include Registerable Securities that
the Stockholder provide written information requested by the Company or the
managing underwriter in a timely manner.

                  (f) The Gartner Group, Inc. ("Gartner") hereby agrees that,
for a period of one (1) year following the first of any Public Offerings,
neither it or any Affiliate (as defined below) will acquire any additional
shares of common stock or other equity securities of the Company, if immediately
after such acquisition Gartner would own, directly or indirectly, more than
thirty-two percent (32%) of any class of common stock or other equity securities
of the Company.

                  For purposes of this Section 2(f), "Affiliate" shall mean,
with respect to any Person, any other Person, directly or indirectly,
controlling, controlled by, or under direct or indirect common control with,
such Person. For the purposes of this definition: "Person" shall mean an
individual, corporation, partnership, joint venture, association, trust,
unincorporated organization or other entity; "control," when used with respect
to any specified Person, shall mean the power to direct or cause the direction
of management and policies of such Person, directly or indirectly, whether
through ownership of voting securities or partnership or other ownership
interests, by contract or otherwise; and "controlling" and "controlled" shall
have correlative meanings.

         3.       MISCELLANEOUS.

                  3.1 GOVERNING LAW. This Agreement shall be governed in all
respects by the internal laws of the State of New York without regard to
conflicts of laws principles. The parties expressly stipulate that any
litigation under this Agreement shall be brought in the state courts of the
County of New York, New York or in the United States District Court for the
Southern District of New York. The parties agree to submit to the jurisdiction
and venue of those courts.

                  3.2 SUCCESSORS AND ASSIGNS. Except as otherwise provided
herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, assigns, heirs, executors and administrators of the
parties hereto.


                  3.3 TRANSFER OR ASSIGNMENT RIGHTS. The rights granted to the
Stockholders by the Company under this Agreement may only be transferred or
assigned by the Stockholders to a transferee or assignee of any of the Shares if
the Company is given notice by the Stockholders prior to the time of said
transfer or assignment, stating the name and address of said transferee or
assignee and identifying the securities with respect to which such rights are
being transferred or assigned; the transferee or assignee of such rights assumes
the obligations of the Stockholders under this Agreement, and provided that (i)
the transfer is in connection with a transfer of all securities of the Company
held by the transferor, (ii) the transferee after the transfer has an aggregate
of at least 100,000 shares of the Registrable Securities (in either case, as
adjusted for stock splits, stock dividends and events of a similar nature),
(iii) the transfer is from one Stockholder to another Stockholder, or (iv) the
transfer or assignment is to constituent partners or stockholders who agree to
act through a single representative.


                  3.4 ENTIRE AGREEMENT; AMENDMENT. This Agreement constitutes
the full and entire understanding and agreement between the parties with regard
to the subjects hereof


                                       3
<PAGE>   4
and thereof, and no party shall be liable or bound to any other party in any
manner by any warranties, representations or covenants except as specifically
set forth herein or therein. Except as expressly provided herein, neither this
Agreement nor any term hereof may be amended, waived, discharged or terminated
other than by a written instrument signed by the party against whom enforcement
of any such amendment, waiver, discharge or termination is sought; provided,
however, that holders of a majority of the Shares (as adjusted for stock splits,
stock dividends and similar events) may, with the prior written consent of the
Company, waive, modify or amend on behalf of all holders, any provisions hereof.

                  3.5 NOTICES, ETC. All notices and other communications
required or permitted in this Agreement shall be in writing, shall be effective

Stockholder's address as set forth on Exhibit A hereto, if to the Company to the
address set forth on the signature page hereto, or at such other address as a
party may designate by ten days' advance written notice to the other party
pursuant to the provisions above.

                  3.6 DELAYS OR OMISSIONS. Except as expressly provided herein,
no delay or omission to exercise any right, power or remedy accruing to any
Stockholder, upon any breach or default of the Company under this Agreement,
shall impair any such right, power or remedy of such holder nor shall it be
construed to be a waiver of any such breach or default, or an acquiescence
therein, or of or in any similar breach or default thereafter occurring; nor
shall any waiver of any single breach or default be deemed a waiver of any other
breach or default theretofore or thereafter occurring. Any waiver, permit,
consent or approval of any kind or character on the part of any holder of any
breach or default under this Agreement, or any waiver on the part of any holder
of any provisions or conditions of this Agreement, must be in writing and shall
be effective only to the extent specifically set forth in such writing. All
remedies, either under this Agreement or by law or otherwise afforded to any
holder, shall be cumulative and not alternative.

                  3.7 COUNTERPARTS. This Agreement may be executed in any number
of counterparts, each of which may be executed by less than all of the
Stockholders, each of which shall be enforceable against the parties actually
executing such counterparts, and all of which together shall constitute one
instrument.

                  3.8 SEVERABILITY. In the event that any provision of this
Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force and
effect without said provision; provided that no such severability shall be
effective if it materially changes the economic benefit of this Agreement to any
party.

                  3.9 TITLES AND SUBTITLES. The titles and subtitles used in
this Agreement are

         months before or at any time after the Review Date requiring the Rent
         to be increased with effect from the Review Date or stating that the
         Rent is not to be increased.

29.2     If the Landlord serves notice requiring the Rent to be increased
         ("Review Notice") the Landlord and the Tenant shall endeavour to agree
         the Open Market Rent as at the Review Date.

29.3     If the Landlord and the Tenant do not agree the Open Market Rent within
         three months after service of a Review Notice or by the date three
         months before the Review Date (whichever is the later) either may by
         notice to the other require the Open Market Rent as at the Review Date
         to be determined by a Chartered Surveyor having at least ten years'
         experience in assessing the rental value of premises similar to the
         Premises and acting as an expert.

<PAGE>   22
29.4     If the Landlord and the Tenant do not agree on the joint appointment of
         an expert the expert shall be nominated on the joint application of the
         Landlord and the Tenant (or if either of them neglects to concur in
         such application then on the sole application of the other) by the
         President or other chief officer or acting chief officer for the time
         being of the Royal Institution of Chartered Surveyors.

         four weeks after his appointment a valuation and representation and
         within a further two weeks written comments on or replies to the
         valuation and/or representations of the other Party but the expert
         shall not be limited or fettered by any submission by either Party and
         shall determine the market rent in accordance with his own judgment and
         his decision shall be binding on both the Landlord and the Tenant.

29.6     The expert shall within three months of his appointment or within such
         extended period as the Landlord may agree give to the Landlord and the
         Tenant written notice of the amount of the Open Market Rent as

         apparent that he will not be able to complete his duties in accordance
         with his appointment the Landlord and the Tenant may agree upon or
         either of them may apply for the appointment of another expert (which
         procedure may be repeated as often as necessary) pursuant to the
         provisions of this clause.

         which Rent was payable immediately prior to the Review Date; and

30.2     If the Rent when ascertained exceeds the Interim Rent then within
         fourteen days of the Rent being ascertained pay to the Landlord an
         amount equal to the aggregate of the sums by which each quarterly
         installment of Rent would have exceeded each installment if Interim
         Rent had the Rent been ascertained by the Review Date together with
         Interest on each of those sums from the date it would have been due to
         the date of payment at a rate 4% below the Interest Rate.

         Where Restrictions are in force at the Review Date the Landlord may
         give notice to the tenant at any time but not later than 28 days after
         the Review Date postponing the Review Date until such later date as the
         Landlord may by not less than three months prior notice specify and in
         that event the rent payable immediately prior to the Review Date that
         is postponed shall continue to be the Rent payable until increased upon
         review at the postponed Review Date.

interest, Owner may at Owner's option and without notice to Tenant add the

the same shall be payable to Owner as additional rent.

                  The parties hereto, for themselves, their heirs, distributees,
executors, administrators, legal representatives, successors and assigns, hereby
covenant as follows:

                  Occupancy: 1. Tenant shall pay the rent as above and as
hereinafter provided.

                  Use. 2. Tenant shall use and occupy demised premises for

                  Requirements of Law, Fire Insurance, Floor Loads: 6. Prior to
the commencement of the lease term, if Tenants is then in possession, and at all
times thereafter, Tenant shall, at Tenant's sole cost and expense, promptly
comply with all present and future laws, orders and regulations of all state,
federal, municipal and local governments, departments, commissions and boards
and any direction of any public officer pursuant to law, and all orders, rules
and regulations of the New York Board of Fire Underwriters, or the Insurance
Services Office, or any similar body which shall impose any violation, order or
duty upon Owner or Tenant with respect to the demised premises, whether or not
arising out of Tenant's use or manner of use thereof, or, with respect to the
building, if arising out of Tenant's use or manner of use of the demised
premises or the building (including the use permitted under the lease). Except
as provided in Article 30 hereof, nothing herein shall require Tenant to make
structural repairs or alterations unless Tenant has, by its manner of use of the
demised premises or method of operation therein, violated any such laws,
ordinances, orders, rules, regulations or requirements with respect thereto.
Tenant shall not do or permit any act or thing to be done in or to the demised
premises which is contrary to law, or which will invalidate or be in conflict
with public liability, fire or other policies of insurance at any time carried
by or for the benefit of Owner. Tenant shall not keep anything in the demised
premises except as now or hereafter permitted by the Fire Department, Board of
Fire Underwriters, Fire Insurance Rating Organization and other authority having
jurisdiction, and then only in such manner and such quantity so as not to
increase the rate for fire insurance applicable to the building, nor use the
premises in a manner which will increase the insurance rate for the building or
any property located therein over that in effect prior to the commencement of
Tenant's occupancy. If by reason of failure to comply with the foregoing the
fire insurance rate shall, at the beginning of this lease or at any time
thereafter, be higher than it otherwise would be, then Tenant shall reimburse
Owner, as additional rent hereunder, for that portion of all fire insurance
premiums hereafter paid by Owner which shall have been charged because of such
failure by Tenant. In any action or proceeding wherein Owner and Tenant are
parties, a schedule or "make-up" or rate for the building or demised premises
issued by a body making fire insurance rates applicable to said premises shall
be conclusive evidence of the facts therein stated and of the several items and
charges in the fire insurance rates then applicable to said premises. Tenant
shall not place a load upon any floor of the demised premises exceeding the
floor load per square foot area which it was designed to carry and which is
allowed by law. Owner reserves the right to prescribe the weight and position of
all safes, business machines and mechanical equipment. Such installations shall
be placed and maintained by Tenant, at Tenant's expense, in settings sufficient,
in Owner's judgement, to absorb and prevent vibration, noise and annoyance.

                  Subordination: 7. This lease is subject and subordinate to all
ground or underlying leases and to all mortgages which may now or hereafter
affect such leases or the real property of which demised premises are a part and
to all renewals, modifications, consolidations, replacements and extensions of
any such underlying leases and mortgages. This clause shall be self-operative
and no further instrument or subordination shall be required by any ground or
underlying lessor or by any mortgagee, affecting any lease or the real property
of which the demised premises are a part. In confirmation of such subordination,
Tenant shall execute promptly any certificate that Owner may request.

                  Property Loss, Damage, Reimbursement, Indemnity: 8. Owner of
its agents shall be liable for any damage to property of Tenant or of others
entrusted to employees of the building, nor for loss of or damage to any
property of Tenant by theft or otherwise, nor for any injury or damage to
persons or property resulting from any cause of whatsoever nature, unless caused
by or due to the negligence of Owner, its agents, servants or employees; Owner
or its agents shall not be liable for any damage caused by other tenants or
persons in, upon or about said building or caused by

                                       3
<PAGE>   4
operations in connection of any private, public or quasi public work. If at any
time any windows of the demised premises are temporarily closed, darkened or
bricked up (or permanently closed, darkened or bricked up, if required by law)
for any reason whatsoever including, but not limited to Owner's own acts, Owner
shall not be liable for any damage Tenant may sustain hereby and Tenant shall
not be entitled to any compensation therefor nor abatement or diminution of rent
nor shall the same release Tenant from its obligations hereunder nor constitute
an eviction. Tenant shall indemnify and save harmless Owner against and from all
liabilities, obligations, damages, penalties, claims, cost and expenses for
which Owner shall not be reimbursed by insurance, including reasonable
attorney's fees, paid suffered or incurred as a result of any breach by Tenant,
Tenant's agents contractors, employees, invitees, or licensees, of any covenant
or condition of this lease, or the carelessness, negligence or improper conduct
of the Tenant, Tenant's agents, contractor, employee, invitee or licensees.
Tenant's liability under this lease extends to the acts and omissions of any
sub-tenant. In case any action or proceeding is brought against Owner any reason
of any such claim, Tenant, upon written notice from Owner will, at Tenant's
expense, resist or defend such action or proceeding by counsel approved by Owner
in writing, such approval not to be unreasonably withheld.

                  Destruction, Fire and Other Casualty: 9. (a) If the demised
premises or any part thereof shall be damaged by fire or other casualty, Tenant
shall give immediate notice thereof to Owner and this lease shall continue in
full force and effect except as hereinafter set forth. (b) If the demised
premises are partially damaged or rendered partially unusable by fire or other
casualty, the damages thereto shall be repaired by and at the expense of Owner
and the rent, until such repair shall be substantially completed, shall be
apportioned from the day following the casualty according to the part of the
premises which is usable. (c) If the demised premises are totally damaged or
rendered wholly unusable by fire or other casualty, then the rent shall be
proportionately paid up to the time of the casualty and thenceforth shall cease
until the date when the premises shall have been repaired and restored by Owner,
subject to Owner's right to elect not to restore the same as hereinafter
provided. (d) If the demised premises are rendered wholly unusable (whether or
not the demised premises are damaged in whole or in part) the building shall be
so damaged that Owner shall decide to demolish it to rebuild it, then, in any of
such events, owner may elect to terminate this lease by written notice to
Tenant, given within 90 days after such fire casualty, specifying a date for the
expiration of the lease, which date shall not be more than 60 days after the
giving of such notice, and upon the date specified in such notice the term of
this lease shall expire as fully and completely as if such date were the date
set forth above for the termination of this lease and Tenant shall forthwith
quit, surrender and vacate the premises without prejudice however, to Owner's
rights and remedies against Tenant under the lease provisions in effect prior to
such termination, and any rent owing shall be paid up to such date and any
payments of rent made by Tenant which were on account of any period subsequent
to such date shall be returned to Tenant. Unless Owner shall serve a termination
notice as provided for herein. Owner shall make the repairs and restorations
under the conditions of (b) and (c) hereof, with all reasonable expedition,
subject to delays due to adjustment of insurance claims, labor troubles and
causes beyond Owner's control. After any such casualty, Tenant shall cooperate
with Owner's restoration by removing from the premises as promptly as reasonably
possible, all of Tenant's salvageable inventory and movable equipment,
furniture, and other property. Tenant's liability for rent shall resume five (5)
days after written notice from Owner that the premises are substantially ready
for Tenant's occupancy. (e) Nothing contained hereinabove shall relieve Tenant
from liability that may exist as a result of damage from fire or other casualty.
Notwithstanding the foregoing, each party shall look first to any insurance in
its favor before making any claim against the other party for recovery for loss
or damage resulting from fire or other casualty, and to the extent that such
insurance is in force and collectible and to the extent permitted by law, Owner
and Tenant each hereby releases and waives all right of recovery against the
other or any one claiming through or

                                       4
<PAGE>   5
under each of them by way of subrogation or otherwise. The foregoing release and
waiver shall be in force only if both releasors' insurance policies contain a
clause providing that such a release or waiver shall not invalidate the
insurance. If, and to the extent, that such waiver can be obtained only by the
payment of additional premiums, then the party benefiting from the waiver shall
pay such premium within ten days after written demand or shall be deemed to have
agreed that the party obtaining insurance coverage shall be free of any further
obligation under the provisions hereof with respect to waiver of subrogation.
Tenant acknowledges that Owner will not carry insurance on Tenant's furniture
and or furnishings or any fixtures or equipment, improvements, or appurtenances
removable by Tenant and agrees that Owner will not be obligated to repair any
damage thereto or replace the same. (f) Tenant hereby waives the provisions of
Section 227 of the Real Property Law and agrees that the provisions of this
article shall govern and control in lieu thereof.

                  Eminent Domain: 10. If the whole or any part of the demised
premises shall be acquired or condemned by Eminent Domain for any public or
quasi public use or purpose, then and in that event, the term of this lease
shall cease and terminate from the date of title vesting in such proceeding and
Tenant shall have no claim for the value of any unexpired term of said lease.

                  Assignment, Mortgage, Etc.: 11. Tenant, for itself, its heirs,
distributees, executors, administrators, legal representatives, successors and
assigns, expressly covenants that it shall not assign, mortgage or encumber this
agreement, nor underlet, or suffer or permit the demised premises or any part
hereof to be used by others, without prior written consent of Owner in each
instance. Transfer of the majority of the stock of a corporate Tenant shall be
deemed an assignment. If this lease be assigned, or if the demised premises or
any part thereof be underlet or occupied by anybody other than Tenant, Owner
may, after default by Tenant, collect rent from the assignee, under-tenant or
occupant, and apply the net amount collected to the rent herein reserved, but no
such assignment, underletting, occupancy or collection shall be deemed a waiver
of this covenant, or the acceptance of the assignee, under-tenant or occupant as
tenant, or a release of Tenant from the further performance by Tenant of
covenants on the part of Tenant herein contained. The consent by Owner to an
assignment or underletting shall not in any wise be construed to relieve Tenant
from obtaining the express consent in writing of Owner to any further assignment
or underletting.

                  Electric Current: 12. Rates and conditions in respect to
submetering or rent inclusion, as the case may be, to be added in RIDER attached
hereto. Tenant covenants and agrees that at all times its use of electric
current shall not exceed the capacity of existing leeders to the building or the
risers or wiring installation and Tenant may not use any electrical equipment
which, in Owner's opinion, reasonably exercised, will overload such
installations or interfere with the use thereof by other tenants of the
building. The change at any time of the character of electric service shall in
no wise make Owner liable or responsible to Tenant, for any loss, damages or
expenses which Tenant may sustain.

                  Access to Premises: 13. Owner or Owner's agents shall have the
right (but shall not be obligated) to enter the demised premises in any
emergency at any time, and, at other reasonable times, to examine the same and
to make such repairs, replacements and improvements as Owner may deem necessary
and reasonably desirable to any portion of the building or which Owner may elect
to perform in the premises after Tenant's failure to make repairs or perform any
work which Tenant is obligated to perform under this lease, or for the purpose
of complying with laws, regulations and other directions of governmental
authorities. Tenant shall permit Owner to use and maintain and replace pipes and
conduits in and through the demised premises and to erect new pipes and conduits
therein provided, wherever possible, they are within walls or otherwise
concealed.

                                       5
<PAGE>   6
Owner may, during the progress of any work in the demised premises, take all
necessary materials and equipment into said premises without the same
constituting an eviction nor shall the Tenant be entitled to any abatement of
rent while such work is in progress nor to any damages by reason of loss or
interruption of business or otherwise. Throughout the term hereof Owner shall
have the right to enter the demised premises at reasonable hours for the purpose
of showing the same to prospective purchasers or mortgagees of the building, and
during the last six months of the term for the purpose of showing the same to
prospective tenants and may, during said six months period, place upon the
premises the usual notices "To Let" and "For Sale" which notices Tenant shall
permit to remain thereon without molestation. If Tenant is not present to open
and permit an entry into the premises. Owner or Owner's agents may enter the
same whenever such entry may be necessary or permissible by master key or
forcibly and provided reasonable care is exercised to safeguard Tenant's
property, such entry shall not render Owner or its agents liable therefor, nor
in any event shall the obligations of Tenant hereunder be affected. If during
the last month of the term Tenant shall have removed all or substantially all of
Tenant's property therefrom. Owner may immediately enter, alter, renovate or
redecorate the demised premises without limitation or abatement of rent, or
incurring liability to Tenant for any compensation and such act shall have no
effect on this lease or Tenant's obligations hereunder.

                  Vault, Vault Space, Area: 14. No Vaults, vault space or area,
whether or not enclosed or covered, not within the property line of the building
is leased hereunder, anything contained in or indicated on any sketch, blue
print or plan, or anything contained elsewhere in this lease to the contrary
notwithstanding. Owner makes no representation as to the location of the
property line of the building. All vaults and vault space and all such areas not
within the property line of the building, which Tenant may be permitted to use
and/or occupy, is to be used and/or occupied under a revocable license, and if
any such license be revoked, or if the amount of such space or area be
diminished or required by any federal, state or municipal authority or public
utility, Owner shall not be subject to any liability nor shall Tenant be
entitled to any compensation or diminution or abatement of rent, nor shall such
revocation, diminution or requisition be deemed constructive or actual eviction.
Any tax, fee or charge of municipal authorities for such vault or area shall be
paid by Tenant, if used by Tenant, whether or not specifically leased hereunder.

                  Occupancy: 15. Tenant will not at any time use or occupy the
demised premises in violation of the certificate of occupancy issued for the
building of which the demised premises are a part. Tenant has inspected the
premises and accepts them as is, subject to the riders annexed hereto with
respect to Owner's work, if any. In any event, Owner makes no representation as
to the condition of the premises and Tenant agrees to accept the same subject to
violations, whether or not of record. If any governmental license or permit
shall be required for the proper and lawful conduct of Tenant's business, Tenant
shall be responsible for and shall procure and maintain such license or permit.

                  Bankruptcy: 16. (a) Anything elsewhere in this lease to the
contrary notwithstanding, this lease may be cancelled by Owner by sending of a
written notice to Tenant within a reasonable time after the happening of any one
or more of the following events: (1) the commencement of a case in bankruptcy or
under the laws of any state naming Tenant as the debtor; or (2) the making by
Tenant of an assignment or any other arrangement for the benefit or creditors
under any state statute. Neither Tenant nor any person claiming through or under
Tenant, or by reason of any statute or order of court, shall thereafter be
entitled to possession of the premises demised but shall forthwith quit and
surrender the premises. If this lease shall be assigned in

                                       6
<PAGE>   7
accordance with its terms, the provisions of this Article 16 shall be applicable
only to the party then owning Tenant's interest in this lease.

                  (b) It is stipulated and agreed that in the event of
termination of this lease pursuant to (a) hereof, Owner shall forthwith,
notwithstanding any other provisions of this lease to the contrary, be entitled
to recover from Tenant as and for liquidated damages an amount equal to the
difference between the rental reserved hereunder for the unexpired portion of
the term demised and the fair and reasonable rental value of the demised
premises for the same period. In the computation of such damages the difference
between any installment of rent becoming due hereunder after the date of
termination and the fair and reasonable rental value of the demised premises for
the period for which such installment was payable shall be discounted to the
date of termination at the rate of four percent (4%) per annum. If such premises
or any part thereof be relet by the Owner for the unexpired term of said lease,
or any part thereof, before presentation of proof of such liquidated damages to
any court, commission or tribunal, the amount of rent reserved upon such
reletting shall be deemed to be the fair and reasonable rental value for the
part or the whole of the premises so re-let during the term of the re-letting.
Nothing herein contained shall limit or prejudice the right of the Owner to
prove for and obtain as liquidated damages by reason of such termination, an
amount equal to the maximum allowed by any statute or rule of law in effect at
the time when, and governing the proceedings in which, such damages are to be
proved, whether or not such amount be greater, equal to, or less than the amount
of the difference referred to above.

                  Default: 17. (1) If Tenant defaults in fulfilling any of the
covenants of this lease other than the covenants for the payment of rent or
additional rent; or if the demised premises becomes vacant or deserted "or if
this lease be rejected under Section 35 of Title 11 of the U.S. Code (bankruptcy
code);" or if any execution or attachment shall be issued against Tenant or any
of Tenant's property whereupon the demised premises shall be taken or occupied
by someone other than Tenant; or if Tenant shall make default with respect to
any other lease between Owner and Tenant; or if Tenant shall have failed, after
five (5) days written notice, to redeposit with Owner any portion of the
security deposited hereunder which Owner has applied to the payment of any rent
and additional rent due and payable hereunder or failed to move into or take
possession of the premises within fifteen (15) days after the commencement of
the term of this lease, of which fact Owner shall be the sole judge; in any one
or more of such events, upon Owner serving a written five (5) days notice upon
Tenant specifying the nature of said default and upon the expiration of said
five (5) days, if Tenant shall have failed to comply with or remedy such
default, or if the said default or omission complained of shall be of a nature
that the same cannot be completely cured or remedied within said five (5) day
period, and if Tenant shall not have diligently commenced during such default
within such five (5) day period, and shall not thereafter with reasonable
diligence and in good faith, proceed to remedy or cure such default, then Owner
may serve a written three (3) days' notice of cancellation of this lease upon
Tenant, and upon the expiration of said three (3) days this lease and the term
thereunder shall end and expire as fully and completely as if the expiration of
such three (3) day period were the day herein definitely fixed for the end and
expiration of this lease and the term thereof and Tenant shall then quit and
surrender the demised premises to Owner but Tenant shall remain liable as
hereinafter provided.

                  (2) If the notice provided for in (1) hereof shall have been
given, and the term shall expire as aforesaid: or if Tenant shall make default
in the payment of the rent reserved herein or any item of additional rent herein
mentioned or any part of either or in making any other payment herein required:
then and in any of such events Owner may without notice, re-enter the demised
premises either by force or otherwise, and dispossess Tenant by summary
proceedings or otherwise, and the

                                       7
<PAGE>   8
legal representative of Tenant or other occupant of demises premises and remove
their effects and hold the premises as if this lease had not been made, and
Tenant hereby waives the service of notice of intention to re-enter or to
institute legal proceedings to that end. If Tenant shall make default hereunder
prior to the date fixed as the commencement of any renewal or extension of this
lease, Owner may cancel and terminate such renewal or extension agreement by
written notice.

                  Remedies of Owner and Waiver of Redemption: 18. In case of any
such default, re-entry, expiration and/or dispossess by summary proceedings or
otherwise, (a) the rent, and additional rent, shall become due thereupon and be
paid up to the time of such re-entry, dispossess and/or expiration, (b) Owner
may re-let the premises or any part or parts thereof, either in the name of
Owner or otherwise, for a term or terms, which may at Owner's option be less
than or exceed the period which would otherwise have constituted the balance of
the term of this lease and may grant concessions or free rent or charge a higher
rental than that in this lease. (c) Tenant or the legal representatives of
Tenant shall also pay Owner as liquidated damages for the failure of Tenant to
observe and perform said Tenant's covenants herein contained any deficiency
between the rent hereby reserved and or covenanted to be paid and the net
amount, if any, of the rents collected on account of the subsequent lease or
leases of the demised premises for each month of the period which would
otherwise have constituted the balance of the term of this lease. The failure of
Owner to re-let the premises or any part or parts thereof shall after making
reasonable efforts to do so not release or affect Tenant's liability for
damages. In computing such reasonable liquidated damages there shall be added to
the said deficiency such expenses as Owner may incur in connection with
re-letting, such as legal expenses, attorneys' fees, brokerage, advertising and
for keeping the demised premises in good order or for preparing the same for
re-letting. Any such liquidated damages shall be paid in monthly installments by
Tenant on the rent day specified in this lease and any suit brought to collect
the amount of the deficiency for any month shall not prejudice in any way the
rights of Owner to collect the deficiency for any subsequent month by a similar
proceeding. Owner, in putting the demised premises in good order or preparing
the same for re-rental may, at Owner's option, make such alterations, repairs,
replacements, and/or decorations in the demised premises as Owner, in Owner's
sole judgement, considers advisable and necessary for the purpose of re-letting
the demised premises, and the making of such alterations, repairs, replacements,
and/or decorations shall not operate or be construed to release Tenant from
liability hereunder as aforesaid. Owner shall in no event be liable in any way
whatsoever for failure to re-let the demised premises, or in the event that the
demised premises are re-let, for failure to collect the rent thereof under such
re-letting, and in no event shall Tenant be entitled to receive any excess, if
any, of such net rents collected over the sums payable by Tenant to Owner
hereunder. In the event of a breach or threatened breach by Tenant of any of the
covenants or provisions hereof, Owner shall have the right of injunction and the
right to invoke any remedy allowed at law or in equity as if re-entry, summary
proceedings and other remedies were not herein provided for. Mention in this
lease of any particular remedy, shall not preclude Owner from any other remedy,
in law or in equity. Tenant hereby expressly waives any and all rights of
redemption granted by or under any present or future laws.

                  Fees and Expenses: 19. If Tenant shall default in the
observance or performance of any term or covenant on Tenant's part to be
observed or performed under or by virtue of any of the terms or provisions in
any article of this lease, then, unless otherwise provided elsewhere in this
lease, Owner may immediately or at any time thereafter and without notice
perform the obligation of Tenant thereunder. If Owner, in connection with the
foregoing or in connection with any default by Tenant in the covenant to pay
rent hereunder, makes any expenditures or incurs any reasonable obligations for
the payment of money, including but not limited to attorney's fees, in
instituting, prosecuting or defending any action or proceedings, then Tenant
will reimburse Owner for

                                       8
<PAGE>   9
such sums so paid or obligations incurred with interest and costs. The foregoing
expenses incurred by reason of Tenant's default shall be deemed to be additional
rent hereunder and shall be paid by Tenant to Owner within five (5) days of
rendition of any bill or statement to Tenant therefor. If Tenant's lease term
shall have expired at the time of making such expenditures or incurring of such
obligations, such sums shall be recoverable by Owner as damages.

                  Building Alterations and Management: 20. Owner shall have the
right at any time without the same constituting an eviction and without
incurring liability to Tenant therefor to change the arrangement and or location
of public entrances, passageways, doors, doorways, corridors, elevators, stairs,
toilets or other public parts of the building and to change the name, number or
designation by which the building may be known. There shall be no allowance to
Tenant for diminution of rental value and no liability on the part of Owner by
reason of inconvenience, annoyance or injury to business arising from Owner or
other Tenant making any repairs in the building or any such alterations,
additions and improvements. Provided Owner shall not unreasonably interfere with
or prevent tenant access to the demised premises. Furthermore Tenant shall not
have any claim against Owner by reason of Owner's imposition of any controls of
the manner of access to the building by Tenant's social or business visitors as
the Owner may deem necessary for the security of the building and its occupants.

                  No Representations by Owner: 21. Neither Owner nor Owner's
agents have made any representations or promises with respect to the physical
condition of the building, the land upon which it is erected or the demised
premises, the rents, leases, expenses of operation or any other matter or thing
affecting or related to the demised premises or the building except as herein
expressly set forth and no rights, easements or licenses are acquired by Tenant
by implication or otherwise except as expressly set forth in the provisions of
this lease. Tenant has inspected the building and the demised premises and is
thoroughly acquainted with their condition and agrees to take the same "as is"
on the date possession is tendered and acknowledges that the taking of
possession of the demised premises by Tenant shall be conclusive evidence that
the said premises and the building of which the same form a part were in good
and satisfactory condition at the time such possession was so taken, except as
to latent defects. All understandings and agreements heretofore made between the
parties hereto are merged in this contract, which alone fully and completely
expresses the agreement between Owner and Tenant and any executory agreement
hereafter made shall be ineffective to change, modify, discharge or effect and
abandonment of it in whole or in part, unless such executory agreement is in
writing and signed by the party against whom enforcement of the change,
modification, discharge or abandonment is sought.

                  End of Term: 22. Upon the expiration or other termination of
the term of this lease, Tenant shall quit and surrender to Owner the demised
premises, broom clean, in good order and condition, ordinary wear and damages
which Tenant is not required to repair as provided elsewhere in this lease
excepted, and Tenant shall remove all its property from the demised premises.
Tenant's obligation to observe and perform this covenant shall survive the
expiration or other termination of this lease. If the last day of the term of
this Lease or any renewal thereof, falls on Sunday, this lease shall expire at
noon on the preceding Saturday unless it be a legal holiday in which case it
shall expire at noon on the preceding business day.

                  Quiet Enjoyment: 23. Owner covenants and agrees with Tenant
that upon Tenant paying the rent and additional rent and observing and
performing all the terms, covenants and conditions, on Tenant's part to be
observed and performed, Tenant may peaceably and quietly enjoy the premises
hereby demised, subject, nevertheless, to the terms and conditions of this lease

                                       9
<PAGE>   10
including, but not limited to, Article 34 hereof and to the ground leases,
underlying leases and mortgages hereinbefore mentioned.

                  Failure to Give Possession: 24. If Owner is unable to give
possession of the demised premises on the date of the commencement of the term
hereof, because of the holding-over or retention of possession of any tenant,
undertenant or occupants or if the demised premises are located in a building
being constructed, because such building has not been sufficiently completed to
make the premises ready for occupancy or because of the fact that a certificate
of occupancy has not been procured or if Owner has not completed any work
required to be performed by Owner, or for any other reason, Owner shall not be
subject to any liability for failure to give possession on said date and the
validity of the lease shall not be impaired under such circumstances, nor shall
the same be construed in any wise to extend the term of this lease, but the rent
payable hereunder shall be abated (provided Tenant is not responsible for
Owner's inability to obtain possession or complete any work required) until
after Owner shall have given Tenant notice that the premises are substantially
ready for Tenant's occupancy. If permission is given to Tenant to enter into the
possession of the demised premises or to occupy premises other than the demised
premises prior to the date specified as the commencement of the term of this
lease. Tenant Covenants and agrees that such occupancy shall be deemed to be
under all the terms, covenants, conditions, and provisions of this lease, except
as to the covenants to pay rent. The provisions of this article are intended to
constitute "an express provision to the contrary" within the meaning of Section
223-a of the New York Real Property Law.

                  No Waiver 25. The failure of Owner or other person to seek
redress for violation of, or to insist upon the strict performance of any
covenant or condition of this lease or of any of the Rules or Regulations, set
forth or hereafter adopted by Owner, shall not prevent a subsequent act which
would have originally constituted a violation from having all the force and
effect of an original violation. The receipt by Owner of rent with knowledge of
the breach of any covenant of this lease shall not be deemed a waiver of such
breach and no provision of this lease shall be deemed to have been waived by
Owner unless such waiver be in writing signed by Owner. No payment by Tenant or
receipt by Owner of a lesser amount than the monthly rent herein stipulated
shall be deemed to be other than on account of the earliest stipulated rent, nor
shall any endorsement or statement of any check or any letter accompanying any
check or payment as rent be deemed an accord and satisfaction, and Owner may
accept such check or payment without prejudice to Owner's right to recover the
balance of such rent or pursue any other remedy in this lease provided. All
checks tendered to Owner as and for the rent of the demised premises shall be
deemed payments for the account of Tenant. Acceptance by Owner of rent from
anyone other than tenant shall not be deemed to operate as an attornment to
Owner by the payor of such rent or as a consent by Owner to an assignment or
subletting by Tenant of the demised premises to such payor, or as a modification
of the provisions of this lease. No act or thing done by Owner or Owner's agents
during the term hereby demised shall be deemed an acceptance of a surrender of
said premises and no agreement to accept such surrender shall be valid unless in
writing signed by Owner. No employee of Owner or Owner's agent shall have any
power to accept the keys of said premises prior to the termination of the lease
and the delivery of keys to any such agent or employee shall not operate as a
termination of the lease or a surrender of the premises

                  Waiver of Trial by Jury: 26. It is mutually agreed by and
between Owner and Tenant that the respective parties hereto shall and they
hereby do waive trial by jury in any action, proceeding or counterclaim brought
by either or the parties hereto against the other (except for personal injury or
property damage) on any matters whatsoever arising out of or in any way
connected with this lease, the relationship of Owner and Tenant, Tenant's use of
or occupancy of

                                       10
<PAGE>   11
said premises, and any emergency statutory or any other statutory remedy. It is
further mutually agreed that in the event Owner commences any summary proceeding
for possession of the premises, Tenant will not interpose any counterclaim of
whatever nature or description in any such proceeding.

                  Inability to Perform: 27. This Lease and the obligation of
Tenant to pay rent hereunder and perform all of the other covenants and
agreements hereunder on part of Tenant to be performed shall in no wise be
affected, impaired or excused because Owner is unable to fulfill any of its
obligations under this lease or to supply or is delayed in supplying any service
expressly or impliedly to be supplied or is unable to make, or is delayed in
making any repair, additions, alterations or decorations or is unable to supply
or is delayed in supplying any equipment or fixtures if Owner is prevented or
delayed from so doing by reason of strike or labor troubles or any cause
whatsoever beyond Owner's sole control including, but not limited to, government
preemption in connection with a National Emergency or by reason of any rule,
order or regulation of any department of subdivision thereto     or by reason of
the conditions of supply and demand which have been or are affected by war or
other emergency.

                  Bills and Notices: 28. Except as otherwise in this lease
provided, a bill, statement, notice or communication which Owner may desire or
be required to give to Tenant, shall be deemed sufficiently given or rendered
it, in writing, delivered to Tenant personally or sent by registered or
certified mail addressed to Tenant at the building of which the demised premises
form a part or at the last known residence address or business address of Tenant

         set forth, or at such other place as Owner may designate in writing,
         without any setoff or deduction whatsoever and without any prior demand
         or notice except as may be otherwise expressly provided for in this
         lease. Failure to deliver any escalation or other statement to Tenant
         shall in no way modify or waive Tenant's obligation to pay any item of
         additional rent otherwise due under the lease.

(D)      All sums, amounts or charges other than annual rent, payable by Tenant
         pursuant to the provisions of this lease, shall be deemed items of
         additional rent, and the failure by Tenant to pay any such item of
         additional rent shall entitle Owner to exercise all remedies for such
         failure which it would be entitled to exercise at law or under this
         lease in respect of any failure to pay annual rent.

(E)      The Tenant shall pay no rent for the month of January 1997. Commencing
         February 1997 through April 1997, tenant shall pay two-thirds (2/3) of
         the monthly rent ($5,541.67) to cover the two month rent concession
         granted by the landlord.

(F)      Tenant shall have access to the premises to do construction work prior
         to the lease commencement date.

ARTICLE 43.                TAX ESCALATION

(A)      Tenant agrees to pay as additional rent eight and 33/100 percent
         (8.33%) of any and all increases in Real Estate Taxes (as hereinbelow
         defined) over and above the Real Estate Taxes payable for the July 1,
         1996 to June 30, 1997 final year (the "Base Tax Year") (such taxes as
         finally determined to be payable for such period, after any certiorari
         or other proceeding, if any, being hereinafter referred to as the "Base
         Taxes") imposed on the Property (as hereinafter defined) with respect
         to every calendar year or part thereof during the term of this lease,
         whether any such increase results from a higher tax rate or an increase
         in the assessed valuation of the Property, or both. "Property" shall
         mean the land and the Building, including any "air rights" or
         "development rights" thereof "Real Estate Taxes" shall mean all taxes,
         assessments, license vault fees, real estate impositions, real estate
         fees and all other governmental charges of any nature whatsoever,
         whether general or special, ordinary or extraordinary, foreseen or
         unforeseen, all of which are imposed upon or in respect of the Property
         (as finally determined to be payable for such period, after any
         Certiorari or other proceeding) including sewer rents and charges and
         water frontage charges (but not water meter charges and the sewer rents
         arising therefrom, if any, which are separately metered to the demised
         premises, and which are paid directly by Tenant or any other tenant of
         the Building), and any special assessment imposed thereon for any
         purpose whatsoever, including taxes payable by Owner to a ground
         lessor, if any, with respect thereto, and any and all expenses
         (including attorney's fees and disbursements) incurred by Owner in
         contesting such Taxes, which expenses shall be allocated to the period
         in which such expenses were


                                       2
<PAGE>   22
         incurred and shall be limited to the amount, if any, of any savings or
         reductions in Taxes resulting from such contest. If due to a change in
         the method of taxation any franchise, income, profit or other tax,
         however designated, shall be levied against Owner's interest in the
         Property in whole or in part for or in lieu of any tax which would
         otherwise constitute Real Estate Taxes, such change in method of
         taxation shall be included in the term "Real Estate Taxes" for purposes
         hereof "Tax Years" shall mean each period of twelve (12) months
         commencing on the first day of July, 1997. All such payments shall be
         appropriately prorated for any partial calendar years occurring during
         the first and last years of the term of this lease. A copy of the tax
         bill of the City of New York (or other governmental agency where
         appropriate) shall be sufficient evidence of the amount of Real Estate
         Taxes and for calculation of the amount to be paid by Tenant.

(B)      The amounts due under this Article shall be collected as additional
         rent without set-off deduction. Owner shall deliver to Tenant a
         statement setting forth the Real Estate Taxes for the Base Tax Year and
         the Real Estate Taxes for the Tax Year concerned or a portion thereof.
         Any adjustment in rent hereunder shall be effective as of the first day
         of the Tax Year concerned and, Tenant shall pay its share of increases
         in Real Estate Taxes within fifteen (15) days before the first day of
         the month in which the Real Estate Taxes for the Tax Year concerned
         become due, provided however, that if Real Estate Taxes for such Tax
         Year are paid by Owner in installments, then Tenant's payments for such
         Tax Year shall be likewise payable in proportionate installments, each
         such installment to be paid at least fifteen (15) days prior to the
         date upon which the corresponding installment of Real Estate Taxes for
         such Tax Year shall become due. In any event any Real Estate Taxes (or
         installment thereof) became due and payable by Owner prior to the
         furnishing to Tenant of a statement, Tenant shall pay Tenant's share of
         increases in Real Estate Taxes (or installments, thereof, if
         applicable) within ten (10) days of the furnishing to Tenant of a
         statement. Such additional rent shall be paid by Tenant notwithstanding
         the fact that Tenant may be exempt in whole or in part, from the
         payment of any Real Estate Taxes by reason of Tenant's diplomatic,
         charitable, non-profit or otherwise tax exempt status, or for any other
         reason whatsoever.

(C)      Owner's failure during the lease term to prepare and deliver any of the
         foregoing tax bills or statements, or Owner's failure to make a demand
         for payment shall not in any waive or cause Owner to forfeit or
         surrender its rights to collect any of the foregoing items of
         additional rent which may have become due during the term of this
         lease. Tenants liability for the amounts due under this Article shall
         survive the expiration of the term. In no event shall any adjustment
         pursuant to this Article result in any reduction in annual rent.

(D)      Upon request of Tenant, Owner agrees to deliver to Tenant a copy of the
         bill(s) for Real Estate Taxes in its possession for any year during the
         term of this lease.

(E)      It is expressly acknowledged that Tenant's failure to pay such tax
         escalation additional rent shall entitle Owner to exercise all remedies
         for such breach which it would be entitled to exercise at law or under
         this lease in respect of any failure to pay annual rent.


                                       3
<PAGE>   23
(F)      Any statement sent to Tenant with respect to escalations hereunder
         shall be biding upon Tenant, unless, within thirty (30) days after such
         statement is sent, Tenant shall send a written notice to Owner
         objecting to such statement and specifying the respects in which such
         statement is claimed to be incorrect. Pending the determination of such
         dispute, Tenant shall pay all additional rent shown on such statement
         and such statement and acceptance shall be without prejudice to
         Tenant's position.

ARTICLE 44.                AS IS; REPAIRS; MAINTENANCE

(A)      Neither Owner nor Owner's agents have made any representations,
         warranties, or promises, either express or implied, with respect to the
         physical condition of the Building or the demised premises, the use or
         uses to which the demised premises or any part thereof may be put, the
         operation of any of the mechanical, plumbing, electrical, ventilation
         or exhaust systems servicing the demised premises, the expenses of
         operation, except as expressly set forth in this lease; and no rights,
         easements, or licenses are acquired by Tenant by implication or
         otherwise except as expressly set forth herein. Tenant acknowledges
         that it has inspected the Building and the demised premises and is
         thoroughly acquainted with their condition, and agrees to take the same
         "as is" except that Landlord shall put the existing bathrooms in
         functional condition and deliver possession of the demised premises
         broom-clean, and except as otherwise set forth in Subarticle (B) below.
         Tenant further acknowledges that taking possession of the demised
         premises shall be conclusive evidence that the demised premises and the
         Building were in good and satisfactory condition at the time such
         possession was so taken. It is expressly understood that Owner shall
         not in any wise be liable for any latent or patent defects in the
         demised premises. Notwithstanding anything contained herein to the
         contrary, Owner shall be responsible for maintaining and repairing
         structural facilities, heating and ventilation (exclusive of air
         conditioning), provided that Tenant does not negligently cause harm to
         the foregoing. Owner shall also be responsible, during the term of this
         lease, for maintaining and repairing electrical, water, and heating
         systems from the source to and on the individual floor herein demised.

(B)      Tenant at its sole cost and expense, shall take good care of the
         demised premises and all improvements and personal property located
         therein, including, without limitation, all furniture, fixtures,
         machinery, equipment and all other personal property and stock
         purchased by Tenant and used in connection with the operation of its
         business at the demised premises, (all of the foregoing being
         hereinafter collectively referred to as "Tenants Property") and Tenant
         shall not suffer or commit any waste or injury thereto. Tenant shall
         make all necessary repairs (other than structural repairs) to the
         demised premises and/or Tenants Property, ordinary, as well as
         extraordinary, foreseen, as well as unforeseen; provided, however, that
         Tenant shall not be obligated to make any repairs including latent
         defects to the extent that the same are necessitated by the negligent
         acts or omissions of Owner, its agents, employees or contractors.
         Tenant shall not be responsible for remediation of environmental
         problems unless caused by Tenant, its agents, employees, contractors or
         visitors during Tenants occupancy of the demised premises.
         Nevertheless, any damage to the Building (including, without
         limitation, the demised premises and the roof), interior and agents,
         servants, employees, invitees or contractors) shall be repaired by
         Tenant, at exterior, arising from or caused by the


                                       4
<PAGE>   24
         negligence or omissions of Tenant or its sole cost and expense,
         regardless of whether such repairs are structural or nonstructural in
         nature.

(C)      When used in Subarticle (B) above, the term "repairs" shall include
         replacements and substitutions of all property when necessary, of a
         quality, class and value at least equal to the property replaced or
         substituted.

ARTICLE 45. SUPPLEMENTING ARTICLE 3 OF THE PRINTED FORM

(A)      Supplementing but not limiting the provisions of Article 3:

(i)           No alteration (as such term is hereinafter defined) shall be made
         that is of a character which involves changes to the steel framework or
         foundations of the Building or affects (a) any part of the Building
         outside of the demised premises, or (b) the proper functioning, or
         overloads the capacity, of the mechanical, electrical, plumbing,
         heating, ventilating, air conditioning or other service systems of the
         building inside or outside the demised premises. Tenant shall not make
         or allow to be made any alterations, additions or improvements to or on
         the demised premises without first obtaining the written consent of
         Owner which consent shall not be unreasonably withheld or delayed. Any
         such alterations, additions or improvements, including but not limited
         to wall covering, paneling and built-in cabinet work, but excepting
         movable furniture and trade fixtures, shall be made at Tenant's sole
         expense, according to plans and specifications approved in writing by
         Owner, in compliance with all applicable laws, by a licensed
         contractor, and in a good and workmanlike manner conforming in quality
         and design with the demised premises existing as of the Commencement
         Date, shall not diminish the value of the Building or the demised
         premises and shall at once become a part of the realty and shall be
         surrendered with the demised premises. Upon the expiration or sooner
         termination of the term hereof, Tenant shall, upon written demand by
         Owner, at Tenant's sole expense, with due diligence, remove any
         alterations, additions or improvements made by Tenant and designated by
         owner to be removed, and repair any damage to the demised premises
         caused by such removal. If Tenant shall fail to remove any of its
         property of any nature whatsoever from the demised premises or Building
         at the termination of this lease such property shall be deemed
         abandoned and Owner may remove and dispose of such property without
         liability for loss thereof such removal to be at the expense of Tenant.

(ii)          Owner will be furnished with a policy or certificate of public
         liability insurance covering Owner in limits of $1,000,000 for personal
         injuries in any one accident or disaster, and $500,000 for property
         damage. Such policy shall be maintained at all times during the
         progress of the work and shall provide that no cancellation shall be
         effective without at least fifteen (15) days prior written notice to
         Owner. Owner shall have the right from time to time during the term of
         this lease to require that Tenant increase the amounts of the coverage
         required to be maintained hereunder to such amounts that are
         customarily required by owners of similar properties in New York City.

                  The term "alteration" as used in this lease shall mean any
improvement, addition, change or installation of, in or to the demised premises,
including, without limitation, any of such involving electrical, air
conditioning, ventilation, heating, plumbing, ceilings, stairways,


                                       5
<PAGE>   25
partitions, demising walls within the demised premises, doors, gates, vaults,
paneling, molding, shelving, radiators, enclosures, floors and floor coverings,
whether or not the same are made in connection with the repair, replacement or
addition to trade fixtures, machinery or equipment, and shall not include
painting or similar decoration. Landlord agrees to not unreasonably withhold or
delay its consent to proposed wallcovering.

ARTICLE 46.                REPAIRS, MAINTENANCE

                  Owner will be notified of all alternations and/or renovations
to be done in the demised premises. Work that has been approved in advance by
both parties would have to be removed at the termination of the lease unless
agreed upon by both parties that such improvement, repair and/or renovation will
remain at the expiration of the said lease.

ARTICLE 47.                LIENS

                  Tenant shall keep the demised premises and the Building free
from any liens arising out of any work performed, materials ordered or
obligations incurred by or on behalf of Tenant, and Tenant hereby agrees to
indemnify and hold Owner, its agents, employees, independent contractors,
officers, directors, partners, and shareholders harmless from any liability,
cost or expense for such liens. Tenant shall cause any such lien imposed to be
released of record by payment or posting of the proper bond acceptable to Owner
within ten (10) days after the earlier of imposition of the lien or written
request by Owner. Tenant shall give Owner written notice of Tenant's intention
to perform work on the demised premises which might result in any claim of lien,
at least ten (10) days prior to commencement of such work. If Tenant fails to
remove any lien within the prescribed ten (10) day period, then Owner may do so
at Tenant's expense and Tenant's reimbursement to Owner for such amount,
including attorneys' fees and costs, shall be deemed additional Rent.

ARTICLE 48.                INSURANCE

         Tenant shall provide on or before the Commencement Date of the term
hereof at its own expense, and keep in force during the term hereof, for the
benefit of Owner, Owner's designees and Tenant a policy of Comprehensive General
Liability insurance with a Bodily Injury Limit of One Million Dollars
($1,000,000) and a Property Damage Limit of Five Hundred Thousand Dollars
($500,000), protecting Owner and Tenant against claims for bodily injury, or
death, and property damage, including water damage, occurring in, upon, or about
the demised premises or any appurtenances thereto. Such policy is to be written
by good and solvent insurance companies satisfactory to Owner. Such insurance
may be carried under a blanket policy covering the demised premises and other
locations of Tenant, if any. Prior to the time such insurance is first required
to be carried by Tenant, and thereafter at least fifteen (15) days prior to the
expiration of any such policy, Tenant agrees to deliver to Owner either a
duplicate original of the aforesaid policy or a certificate evidencing such
insurance, together with evidence of payment for the policy.

         All of the aforesaid insurance shall be in the name of Owner, and all
other designees of Owner, and all other designees of Owner, and Tenant, and
shall contain endorsements that: (I) such insurance may not be cancelled or
amended with respect to Owner (or its designees(s),



                                       6
<PAGE>   26
except upon twenty (20) days written notice by registered mail to Owner and such
designees by the insurance company); and (ii) Tenant shall be solely responsible
for payment of premiums and that Owner and its designees shall not be required
to pay any premiums for such insurance. The minimum limits of the comprehensive
general liability policy of insurance shall in no way limit or diminish Tenant's
liability under other provisions of this lease.

         Tenant's failure to provide and keep in force the aforementioned
insurance shall be regarded as a material default hereunder, entitling Owner to
exercise any or all of the remedies provided in this lease in the event of
Tenant's default.

         Owner shall have the right to require Tenant to increase the amount of
coverage under such policy or policies consistent with amounts customarily
required by owners of similar properties in New York City, provided, however,
that such amount shall not be increased by more than five percent (5%)
cumulative per annum.

         Any delay by Owner in exercising, failing to exercise, any right
hereunder shall not be deemed a waiver of said right.

ARTICLE 49.                ELECTRICITY

(A)      Tenant shall arrange for and pay as additional rent all charges for
         electricity used or consumed on the demised premises and shall hold
         Owner harmless from any and all liabilities, liens, costs and expenses
         arising therefrom. All electricity charges shall be paid directly by
         Tenant to the utility company.

                  Notwithstanding anything to the contrary contained in this
lease, Tenant shall, at Tenant's sole cost and expense, maintain and promptly
make all repairs, structural and nonstructural, to all components of the
electrical system from the meter socket and end-line connection for the floor to
and through the demised premises floor.

(B)      Owner shall not be liable for any loss suffered by Tenant by reason of
         interruption or discontinuance of electric service.

(C)      Tenant covenants and agrees that at all times its use of electric
         current shall never exceed the capacity of existing feeders to the
         demised premises or the capacity of the risers or wiring installation
         in the Building. Tenant agrees not to connect any additional electrical
         equipment to the building electric distribution system, other than
         computers, telephone, telefax machines, copying machines, typewriters
         and other office machines which consume comparable amounts of
         electricity, without Owner's prior written consent. In the event
         Tenant's electrical requirements require the installations of any
         additional risers, Tenant shall request Owner's written approval of
         same, which approval may be withheld by Owner for any reason
         whatsoever. If Owner approves such installation, Owner shall install
         such risers at Tenant's sole cost and expense provided that such
         installation will not cause permanent damage or injury to the Building
         or the demised premises or cause or create a dangerous or hazardous
         condition or entail excessive or unreasonable alterations, repairs or
         expense or interfere with or disturb other tenants or occupants of the
         Building. If Owner shall consent to the installation of such riser or
         risers, which consent can be withheld for any reason, Owner at Tenant's
         sole cost and



                                       7
<PAGE>   27
         expense, shall also install other equipment necessary and proper in
         connection therewith subject to the aforesaid terms and conditions.

ARTICLE 50.                LATE FEES

         Tenant hereby acknowledges that late payment to Owner of Rent,
Additional Rent or other sums due hereunder will cause Owner to incur costs not
contemplated by this lease, the exact amount of which will be extremely
difficult to ascertain. If any Rent, Additional Rent or other sum due from
Tenant is not received by Owner or Owner's designated agent within ten (10) days
of when due, then Tenant shall pay to Owner a late charge equal to five percent
(5%) of such overdue amount, plus any attorneys' fees and costs incurred by
Owner by reason of Tenant's failure to pay Rent and other charges within ten
(10) days of when due hereunder. The parties hereby agree that such late charges
represent a fair and reasonable estimate of the cost that owner will incur by
reason of Tenant's late payment. Owner's acceptance of such late charges shall
not constitute a waiver of Tenant's default with respect to such overdue amount
or estop Owner from exercising any of the other rights and remedies granted
hereunder.

ARTICLE 51.                DELAY IN VACATION OF DEMISED PREMISES

(A)      Tenant agrees it shall indemnify and save Owner harmless against all
         costs, claims, loss or liability resulting from delay by Tenant in
         surrendering the demised premises upon the expiration or earlier
         termination of this lease, including, without limitation, any claims
         made by any succeeding tenant founded on such delay.

(B)      The parties recognize and agree that the damage to Owner resulting from
         any failure by Tenant timely to surrender the demised premises will be
         substantial, will exceed the amount of monthly installments of annual
         rent theretofore payable hereunder, and will be impossible of accurate
         measurement. Tenant therefore agrees that if possession of the demised
         premises is not surrendered to Owner upon the expiration or earlier
         termination of the term of this lease, then and in such event Tenant
         shall pay Owner, as liquidated damages for each month and for each
         portion of any month during which Tenant holds over in the demised
         premises after the expiration or termination of the term of this lease,
         a sum equal to the greater of the (I) fair market rental at the
         expiration of the term and (ii) the highest annual rent and additional
         rent which was payable by Tenant per month under this lease. The
         provisions of this Subarticle (B) will not limit, reduce or otherwise
         affect the liability of Tenant under Subarticle (A) of this Article.

ARTICLE  52.               SUPPLEMENTING ARTICLE 11 OF THE PRINTED FORM

(A)      Without limiting the scope of Article 11 it is expressly acknowledged
         that any assignment or transfer of the shares of stock of any corporate
         tenant (by single or multiple transactions), the effect of which is a
         transfer of the majority of the issued and outstanding capital stock of
         the corporate tenant or the effect of which transfers control of such
         corporation to any person or persons who were not stockholders thereof
         at the time such corporate tenant acquired Tenant's leasehold estate
         hereunder, or any merger of a corporate tenant into, or consolidation
         of a corporate tenant with another corporation, shall be conclusively
         deemed an assignment under the terms of the lease. Owner may



                                       8
<PAGE>   28
         request at any time and Tenant shall deliver within ten (10) days after
         such request a list of the names and addresses of all stockholders,
         officers and directors of a corporate tenant, which lists shall be
         sworn to by the chief executive officer of Tenant.

                  Notwithstanding anything contained herein to the contrary in
the event of an arms-length bona fide sale of Tenant's business, Owner hereby
consents to the assignment of this lease to the purchaser of Tenant's business
or subletting of 30% of demised premises for the remainder of the term provided
that the assignee assumes all of the Tenant's obligations hereunder. Tenant
shall remain liable for all of its obligations under this lease notwithstanding
any assignment of this lease or subletting of the demised premises. Owner shall
not be entitled to the payment of any fees or concessions in the event of an
assignment of the lease or subletting of 30% of demised premises for the
remainder of the term entered into in connection with an arms-length bona fide
sale of Tenant's entire business.

(B)      In the event that Tenant shall at any time or times during the term of
         this lease desire to assign this lease or sublet all or a portion of
         the demised premises, Tenant shall give notice thereof to Owner and
         shall submit and otherwise comply with the following:

(i)      The name of the proposed assignee or sublessee and the
   character of its business;

(ii)     The activities to be conducted in and the use to be made of
    the demised premises by the proposed assignee or sublessee;

(iii)    The terms and conditions of the proposed assignment or
     subletting;

(iv)     In the case of a proposed subletting of a portion of the
    demised premises, a reasonably accurate floor plan of the portion of the
    demised premises and to be sublet;

(v)      Financial information or credit information pertaining to the
    proposed assignee (not required for sublessee) sufficient to enable Owner to
    evaluate its financial responsibility; and

(vi)     A representation that the proposed assignee or sublessee is
    not a tenant, subtenant or occupant of other space in the Building.

                  During the period of thirty (30) days after receipt by Owner
         of the foregoing information Owner will notify Tenant of its election
         either to grant or deny its consent to such assignment or subletting.
         Owner agrees not to unreasonably withhold or delay its consent to any
         proposed assignment or subletting.

                  If no such notice is given to Tenant, it shall be deemed that
         Owner has elected to refuse or withhold consent to the proposed
         assignment or subletting.

(C)      Any assignment or subletting made in contravention of the provisions of
         this Article shall not be binding upon Owner, and, at Owner's option,
         may be treated as a nullity, and of no force and effect whatsoever as
         against Owner. No assignment of this lease or subletting of the demised
         premises (whether with or without Owner's consent), shall operate or be
         construed to release or diminish Tenant's liability under this lease,
         and such liability shall continue in full force and effect. Moreover,
         no assignment or subletting (whether with or



                                       9
<PAGE>   29
         without  Owner's consent) shall operate to relieve Tenant of the
         necessary of compliance with all of the provisions of this Article with
         respect to any further assignment or subletting.

(D)      If the demised premises shall be sublet or occupied by any person or
         persons other than Tenant, Owner may, after default by Tenant, collect
         rent from the subtenant or occupant and apply the net amount collected
         to the rent herein reserved, but no such subletting, occupancy or
         collection of rent shall be deemed a waiver of the covenants in this
         Article, nor shall it be deemed an acceptance of the subtenant or
         occupant as a tenant, or a release of Tenant from the full performance
         by Tenant of all the terms, conditions and covenants of this lease.

(E)      In the event of a sublet consented to by Owner, one hundred percent
         (100%) of the Net Profit for each calendar year shall be paid quarterly
         to Owner, as additional rent. For the purpose of this Article, "Net
         Profit" for any calendar year shall mean the amount by which "Gross
         Receipts" actually paid to Tenant in connection with any subletting
         exceed "Gross Expenses" of Tenant with respect to the demised premises
         for such calendar year. The Net Profit and Gross Receipts shall be
         computed and paid with respect to all subleases in effect.



         "Gross Receipts" of Tenant shall mean all rentals and any other sums
paid to Tenant including, without limitation, sums paid to acquire the lease or
sublease, fixture fees, electricity charges, "key money," and any other
consideration paid by any subtenant with respect to the demised premises during
the calendar year in question.

         "Gross Expenses" of Tenant with respect to the demised premises for any
calendar year shall mean all rent, additional rent and other sums payable by
Tenant to Owner under this Lease for such calendar year and shall not include
any other expenditures paid or incurred by Tenant except customary brokerage
fees and reasonable attorneys' fees actually paid by Tenant in connection with
such subletting.

         Within thirty (30) days after the end of each quarter of each calendar
year during the term of this lease, Tenant shall deliver to Owner a statement
sworn to by an officer of Tenant setting forth the Gross Receipts and Gross
Expenses for such quarter and the computation of the Net Profit, if any, for
such quarter, together with any payment for any Net Profit which may be due
pursuant to this Article. If any such statement contains an untrue statement or
fails to include a complete statement of Gross Receipts, then Tenant shall be
deemed to be in material default under this lease and Owner shall be entitled to
terminate this lease in addition to exercising any other remedy available to it
in law or in equity.

         For the period of two (2) years after any statement required by this
Article has been sent by Tenant to Owner, Owner shall have the opportunity to
examine the books of Tenant at Tenant's office, upon reasonable notice to Tenant
and within reasonable hours, in order to determine the accuracy of such
statement(s).

         The obligations of Tenant under this subarticle (E) shall survive the
expiration or termination of this lease.


                                       10
<PAGE>   30
(F)      Each assignee shall assume and be deemed to have assumed this lease and
         shall be and remain liable for the payment of the rent and additional
         rent, and for the due performance of all the terms, covenants,
         conditions and agreements on Tenant's part to be performed during the
         term of this lease. No assignment shall be binding on Owner unless the
         assignee of Tenant shall deliver to Owner an instrument in recordable
         form which contains an assumption by the assignee, but the failure or
         refusal of the assignee to execute or deliver such instrument shall not
         relieve the assignee from liability as provided in this Subarticle.

(G)      Each sublessee shall be and remain liable for the payment of rent, and
         for the due performance of all the terms, covenants, conditions, and
         agreement on the sublessee's part to be performed during the term of
         the sublease. Every sublease shall contain a provision stating that the
         sublease is subject and subordinate to the estate created under as well
         as to the terms and provisions of this lease. In the event of a
         permitted subletting, the sublease shall contain a provision pursuant
         to which in the event of a termination of this lease for any reason
         whatsoever, Owner shall have the right, at its election, to require the
         subleasee to attom to and recognize Owner as the subleasee's owner as
         of the commencement date of the sublease. In the event of a permitted
         subletting of a portion of the demised premises, the sublease shall
         contain a provision whereby Tenant agrees, at its sole cost, to provide
         the subleasee with reasonably appropriate means of ingress to and from
         the space subleased and Tenant further agrees to restore the space to
         it original condition.

ARTICLE 53.                INDEMNITY

         Without limiting any other indemnity extended by Tenant to Owner under
the provisions of this lease, Tenant hereby indemnifies and agrees to hold Owner
harmless from and against any and all damage, judgment, loss, liability, claim,
cost and/or expense (including, without limitation, reasonable attorneys' fees
and disbursements) in connection with or arising from any default by Tenant
under this lease, Tenant's misuse or occupancy of the demised premises, and/or
any acts, omissions or the negligence of Tenant, its employees, servants,
contractors, agents, licensees and invitees in or about the demised premises,
the Building and sidewalks, if any, adjoining the Building.

ARTICLE 54.                SUPPLEMENTING ARTICLE 18 OF THE PRINTED FORM

         In the event of termination of this lease pursuant to Article 18,
Tenant shall pay to Owner immediately all rental and other charges payable
hereunder due and unpaid to the date of termination together with an amount
which is equal to the then-present value (using a discount rate equal to the
then-applicable discount rate at the Federal Reserve Bank nearest to the
location of the Building, plus two (2%) percent per annum) of the whole Rent for
the balance of the Term of this lease (including any extension terms which have
been elected) as hereinafter computed. In the event any judgment has been
entered against Tenant for any amount in excess of the total amount required to
be paid by Tenant to Owner hereunder, then the damages assessed under said
judgment shall be reassessed and a credit granted to the extent of such excess.
The parties hereto acknowledge that the damages to which Owner is entitled in
the event of a breach of this lease and termination by Owner are not easily
computed and are subject to many variable factors. The


                                       11
<PAGE>   31
parties have therefore agreed to the liquidated damages as herein provided in
order to avoid extended litigation in the event of default by Tenant and
termination of this lease.

         Rent for each year for the balance of the term, for the purpose of
computing the rent reserved hereunder for the unexpired portion of the Term,
shall be computed (I) for minimum annual rental, based upon the schedule for
minimum annual rental set forth in the lease, and (ii) for escalations and
Additional Rent, as equal to the yearly average of the escalations and
Additional Rent payable by Tenant for the last three (3) full calendar years
immediately preceding said Event of Default. If three (3) full calendar years
have not preceded the occurrence of said Event of Default, then the annual
average of escalations and Additional Rent payable by Tenant theretofore
required to be paid by Tenant shall be used, in the computation of the
escalations and rent.

ARTICLE 55.                ACCESS

         Tenant agrees to indemnify and hold harmless Owner from any costs,
expense, liability, damages, judgments, or fees, including legal fees, arising
out of or in connection with Tenant's negligence when entering, using or exiting
the building and demised premises. Tenant is responsible for repairing and
replacing any property vandalized, damaged or stolen if Tenant fails to properly
close the doors or is otherwise negligent.

ARTICLE 56.                SUPPLEMENTING ARTICLE 32 HEREOF

         Owner shall maintain the security deposit in an interest-bearing
account. Owner shall be entitled to an administrative fee of 1% of the amount of
the security deposit per annum, and, provided that Tenant is not then in default
hereunder, the interest shall be paid to the Tenant once a year on each
September 1.

ARTICLE 57.                MISCELLANEOUS

(A)      Owner and Tenant each represent and warrant to the other that no broker
         brought about the letting contemplated by this lease, and that they
         have not contacted any broker in connection with this transaction other
         than Tarter/Stats Realty (the "Broker"). Owner shall pay the commission
         due and payable to the Broker pursuant to a separate agreement. Tenant
         and Owner shall each indemnify and save the other harmless from and
         against all loss, claim, liability, damage or suit incurred or suffered
         by the other arising out of or in connection with any breach of the
         indemnifying party's representations set forth in this Subarticle (A).

(B)      Whenever the performance of any duties or obligations on the part of
         Tenant reasonably contemplates such performance or discharge after the
         termination of this lease, such duties and obligations shall survive
         any expiration or sooner termination of this lease.

(C)      Tenant agrees that its sole remedy in cases where Owner's
         reasonableness in exercising its judgment or withholding its consent or
         approval is applicable and in issue shall be those in the nature of an
         injunction, declaratory judgment or specific performance, the rights to
         any money damages or other remedies being hereby specifically waived.


                                       12
<PAGE>   32
(D)      Owner shall have the right to alter or to construct additions to the
         Building; provided however, that any such alteration or construction
         will not materially interfere with the demised premises or Tenant's
         business therein. In connection with any such alteration or
         construction, Owner shall have the right to utilize and hook up with
         all existing risers, conduits and other piping in the Building and to
         construct scaffolding as may be required by law, such work to be
         performed at Owner's expense.

(E)      Owner shall have the right from time to time to change the name, number
         or designation by which the Building is commonly known.

(F)      Without limiting anything otherwise set forth in the Rules and
         Regulations, no awning, canopy or other projections, whether they
         contain or do not contain advertising material may be attached to any
         portion of the Building without the prior written consent of Owner.
         Further, Tenant shall not post or erect or maintain outside the windows
         or show windows nor on any exterior construction, any signs, placards
         or other advertisements, except with the prior written approval of
         Owner. However, Tenant may post signs, placards or other advertisements
         to the interior of the windows if professionally prepared by a sign
         company. Tenant shall not make any use whatsoever of the area beyond
         the building line. No hanging outside sips will be approved nor will
         any papered signs posted on the windows or show windows of the demised
         premises be approved unless the same are required to be so posted at
         such location by law. If Tenant violates the provisions of this
         Subarticle, then in addition to and without limiting Owner's remedies
         under this lease, Owner may itself remove any such sign, placard,
         advertisement or display without liability or obligation to Tenant and,
         if necessary, to carry out the foregoing, Owner may enter the demised
         premises to effect such removal. The parties acknowledge that a breach
         of the provisions of this Subarticle shall be deemed a material breach
         of this lease.

(G)      Owner, its constituent partners and, if applicable, its shareholders
         and officers shall not have any personal liability to Tenant by reason
         of any default by Owner under any of Owner's covenants and agreements
         under this lease. In the event of such default Tenant shall look only
         to Owner's estate in the Building to recover any loss or damage
         resulting therefrom and Tenant shall have no right to assert any claim
         nor obtain any injunction against any recourse to Owner's other
         property or assets or that of any of the shareholders or officers of
         Owner to recover such loss or damage.

(H)      If any term, covenant, condition or provision of this lease, or the
         application thereof to any person or circumstances shall, to any
         extent, be invalid or unenforceable, the remainder of this lease, or
         the application of such term, covenant or provision to persons or
         circumstances other than those as to which it is held invalid or
         unenforceable, shall not be affected thereby and each term, covenant or
         condition of this lease shall be valid and enforceable to the fullest
         extent permitted by law.

(I)      Tenant shall at all times enforce good order among its employees.
         Subject to the provisions of Tenant's applicable union contract, Tenant
         will not employ any person or do anything which will cause union or
         labor difficulties or conflicts with the Building, Owner or Owner's
         employees. In case of such conflict, Tenant will comply with the


                                       13
<PAGE>   33
         reasonable direction of Owner and failure so to do shall be deemed a
         material breach of this lease.

(J)      All notices required or permitted to be given hereunder shall be sent
         by certified mail, return receipt requested, addressed as follows:

like manner. All notices shall be deemed given when mailed, except for notice of
change of address or party to receive notice, which shall be deemed given only

(K)      Wherever in this lease, Owner's consent is required, except where
         otherwise expressly set forth, such consent may be granted or withheld
         in Owner's sole and arbitrary discretion and such consent shall not be
         unreasonably withheld.

(L)      If more than one person or entity executes or otherwise assumes or
         becomes liable under this lease, the obligations of Tenant shall be the
         joint and several obligations of each of them.

(M)      Tenant covenants not to introduce any hazardous or toxic materials onto

         and b) complying with all applicable Federal, State and local laws or
         ordinances pertaining to the transportation, storage, use or disposal
         of such materials, including but not limited to obtaining proper
         permits. If Tenant's transportation, storage, use or disposal of
         hazardous or toxic materials on the demised premises results in the
         contamination of the demised premises or the Building, or the soil or
         surface or ground water or loss or damage to person(s) or property,
         then Tenant agrees to: 1) notify Owner immediately of any
         contamination, claim of contamination, loss or damage, 2) after
         consultation with Owner, clean up the contamination in full compliance
         with all applicable statutes, regulations and standards, and 3)
         indemnify, defend and hold Owner harmless from and against any claims,
         suits, causes of action, costs and fees, including attorneys' fees and
         costs, arising from or connected with any such contamination, claim of
         contamination, loss or damage. This


                                       14
<PAGE>   34
         provision shall survive termination of this lease. Nothing in this
         Article shall be construed to hold Tenant responsible for the cleanup
         required because of any spills or discharges of hazardous substances
`        caused by Owner, or its agents, contractors, employees or invitees or
         occurring prior to or after Tenant's occupancy of the demised premises.

(N)      Tenant shall not suffer or permit the demised premises or any part
         thereof to be used in any manner which would in any way (i) constitute
         a public or private nuisance; or (ii) impair or interfere with the use
         of any of the other areas of the Building by, or occasion discomfort,
         annoyance or inconvenience to, Owner or any of the other tenants or
         occupants of the Building, any such impairment or interference to be in
         the sole judgment of Owner. Tenant acknowledges that Tenant's failure
         to comply with the terms hereof shall constitute a material breach of
         this lease entitling Owner to all rights and remedies it may have under
         this lease and at law.

(O)      Prior to the execution of this lease by Owner, Tenant shall supply
         Owner with a copy of resolutions duly certified by the Secretary of
         Tenant, of the Board of Directors of Tenant, to the effect that:

(i)      Tenant is duly authorized and empowered to enter into this lease; and

(ii)     The President of Tenant has been duly authorized, empowered and
    directed by said Board of Directors to enter into this lease on behalf of
    Tenant.

(P)      This lease is offered to Tenant for signature with the understanding
         that it shall not be binding upon Owner unless and until Owner shall
         have executed and unconditionally delivered to Tenant a fully executed
         copy of the lease.

(Q)      Those provisions on the front page of the printed portion of this lease
         and in Article 17 concerning defaults by Tenant under any other lease
         between Tenant and Owner shall apply to any and all other leases
         between Owner and Tenant, whether or not such leases are subsidiary to
         this lease or for space adjacent to the demised premises.

(R)      Tenant agrees that the value of the demised premises and the reputation
         of Owner will be seriously injured if the demised premises are used for
         any obscene or pornographic purposes or any sort of commercial sex
         establishment. Tenant agrees that Tenant will not bring or permit any
         obscene or pornographic material on the demised premises, and shall not
         permit or conduct any obscene, nude, or semi-nude live performances on
         the demised premises, nor permit use of the demised premises for nude
         modeling, rap sessions, or as a so-called rubber goods shop, or as a
         sex club of any sort, or as a "massage parlor." Tenant agrees further
         that Tenant will not permit any of these uses by any sublessee of all
         or any portion of the demised premises or any assignee of this lease.
         This Article shall directly bind any successors in interest to the
         Tenant. Tenant agrees that if at any time Tenant violates any of the
         provisions of this Article, such violation shall be deemed a breach of
         a substantial obligation of the terms of this lease and objectionable
         conduct. Pornographic materials is defined for purposes of this Article
         as any written or pictorial matter with prurient appeal or any objects
         or instrument that are primarily concerned with


                                       15
<PAGE>   35
         lewd or prurient sexual activity. Obscene material is defined here as
         it is in Penal Law Section 235.00.

(S)      Owner shall provide one (1) directory listings for Tenant on each of
         the directories in the ground floor and 10th floor lobbies. Tenant may,
         at its sole cost and expense, affix to the entrance door to the demised
         premises a sign with Tenant's name, subject to Owner's prior written
         approval, which shall not be reasonably withheld, of the appearance,
         materials and size of such sign.

ARTICLE 58.

all necessary applications, plans and documents with the respective governmental
agencies and obtains written approval for all work from the governing
authorities. All work performed shall be done by licensed contractors and in
accordance with all NYC building codes and regulations and only in accordance
with written plans which must be submitted and approved by the landlord as well
as the governing authorities. Tenant agrees it shall indemnify and save owner
harmless against all costs, claims, loss or liability resulting from the
aforementioned work and shall provide written proof of insurance policies naming

any set off or deduction whatsoever, except that Tenant shall pay the first
monthly installment(s) on the execution hereof (unless this lease be a renewal).

                  In the event that, at the commencement of the term of this
lease, or thereafter, Tenant shall be in default in the payment of rent to Owner
pursuant to the terms of another lease with Owner or with Owner's predecessor in
interest, Owner may at Owner's option and without notice to Tenant add the
amount of such arrears to any monthly installment of rent payable hereunder and
the same shall be payable to Owner as additional rent.

                  The parties hereto, for themselves, their heirs, distributees,
executors, administrators, legal representatives, successors and assigns, hereby
convenant as follows:

                  Rent Occupancy:   1.      Tenant shall pay the rent as above

interior of the demised premises by using contractors or mechanics first
approved by Owner. Tenant shall, before making any alterations, additions,
installations or improvements, at its expense, obtain all permits, approvals and
certificates required by any governmental or quasi-governmental bodies and (upon

duplicates of all such permits,approvals and certificates to Owner and Tenant
agrees to carry and will cause Tenant's contractors and sub-contractors to carry
such workman's compensation, general liability, personal and property damage

partitions, railings and like installations, installed in the premises at any
time, either by Tenant or by Owner in Tenant's behalf, shall, upon installation,

demised premises unless Owner, by notice to Tenant no later than twenty days
prior to the date fixed as the termination of this lease, elects to relinquish
Owner's right thereto and have them removed by Tenant, in which event the same
shall be removed from the premises by Tenant prior to the expiration of the
lease, at Tenant's expense. Nothing in this Article shall be construed to give

furniture and equipment, but upon removal of any such from the premises or upon
removal of other installations as may be required by Owner, Tenant shall

Owner, at Tenant's expense.

         Maintenance and Repairs: 4.     Tenant shall, throughout the term of
this lease, take good care of the demised premises and the fixtures and
appurtenances therein. Tenant shall be responsible for all damage or injury to

may be responsible hereunder. There shall be no allowance to Tenant for
diminution of rental value and no liability on the part of Owner by reason of
inconvenience, annoyance or injury to business arising from Owner or others
making repairs, alterations, additions or improvements in or to any portion of
the building or the demised premises or in and to the fixtures, appurtenances or
equipment thereof. It is specifically agreed that Tenant shall not be entitled

         Window Cleaning: 5. Tenant will not clean nor require, permit, suffer
or allow any window in the demised premises to be cleaned from the outside in
violation of Section 202 of the Labor Law or any other applicable law or of the
Rules of the Board of Standards and Appeals, or of any other Board or body
having or asserting jurisdiction.

         Requirements of Law, Fire Insurance, Floor Loads: 6. Prior to the
commencement of the lease term, if Tenant is then in possession, and at all time
thereafter, Tenant, at Tenant's sole cost and expense, shall promptly comply
with all present and future laws, orders and regulations of all state, federal,
municipal and local governments, departments, commissions and boards and any
direction of any public officer pursuant to law, and all orders, rules and
regulations of the New York Board of Fire Underwriters, Insurance Services
Office, or any similar body which shall impose any violation, order or duty upon
Owner or Tenant with respect to the demised premises, whether or not arising out
of Tenant's use or manner of use thereof, (including Tenant's permitted use) or,
with respect to the building if arising out of Tenant's use or manner of use of
the premises or the building (including the use permitted under the lease).
Nothing herein shall require Tenant to make structural repairs or alterations
unless Tenant has, by its manner of use of the demised premises or method of
operation therein, violated any such laws, ordinances, orders, rules,
regulations or requirements with respect thereto. Tenant may, after securing
Owner to Owner's satisfaction against all damages, interest, penalties and
expenses, including, but not limited to, reasonable attorney's fees, by cash
deposit or by surety bond in an amount and in a company satisfactory to Owner,
contest and appeal any such laws, ordinances, orders, rules, regulations or
requirements provided same is done with all reasonable promptness and provided
such appeal shall not subject Owner to prosecution for a criminal offense or
constitute a default under any lease or mortgage under which Owner may be
obligated, or cause the demised premises or any part thereof to be condemned or
vacated. Tenant shall not do or permit any act or thing to be done in or to the
demised premises which is contrary to law, or which will invalidate or be in
conflict with public liability, fire or other policies of insurance at any time
carried by or for the benefit of Owner with respect to the demised premises or
the building of which the demised premises form a part, or which shall or might
subject Owner to any liability or responsibility to any person or for property
damage. Tenant shall not keep anything in the demised premises except as now or
hereafter permitted by the Fire Department, Board of Fire Underwriters, Fire
Insurance Rating Organization or other authority having jurisdiction, and then
only in such manner and such quantity so as not to increase the rate for fire
insurance applicable to the building, nor use the premises in a manner which
will increase the insurance rate for the building or any property located
therein over that in effect prior to the commencement of Tenant's occupancy.
Tenant shall pay all costs, expenses, fines, penalties, or damages, which may be
imposed upon Owner by reason of Tenant's failure to comply with the provisions
of this article and if by reason of such failure the fire insurance rate shall,
at the beginning of this lease, or at any time thereafter, be higher than it
otherwise would be, then Tenant shall reimburse Owner, as additional rent
hereunder, for that portion of all fire insurance premiums thereafter paid by
Owner which shall have been charged because of such failure by Tenant. In any
action or proceeding wherein Owner and Tenant are parties, a schedule or
"make-up" of rate for the building or demised premises issued by the New York
Fire Insurance Exchange, or other body making fire insurance rates applicable to
said premises shall be conclusive evidence of the facts therein stated and of
the several items and charges in the fire insurance rates then applicable to
said premises. Tenant shall not place a load upon any floor of the demised
premises exceeding the floor load per square foot area which it was designed to


                                       3
<PAGE>   4
carry and which is allowed by law. Owner reserves the right to prescribe the
weight and position of all safes, business machines, and mechanical equipment.
Such installations shall be placed and maintained by Tenant, at Tenant's
expense, in settings sufficient, in Owner's judgement, to absorb and prevent
vibration, noise and annoyance.

         Subordination: 7. This lease is subject and subordinate to all ground
or underlying leases and to all mortgages which may now or hereafter affect such
leases or the real property of which demised premises are a part and to all
renewals, modifications, consolidations, replacements and extensions of any such
underlying leases and mortgages. This clause shall be self-operative and no
further instrument of subordination shall be required by any ground or
underlying lessor or by any mortgagee, affecting any lease or the real property
of which the demised premises are a part. In confirmation of such subordination,
Tenant shall execute promptly any certificate that Owner may request.

         Property Loss, Damage, Reimbursement, Indemnity: 8. Owner or its agents
shall not be liable for any damage to property of Tenant or of others entrusted
to employees of the building, nor for loss of or damage to any property of
Tenant by theft or otherwise, nor for any injury or damage to persons or
property resulting from any cause of whatsoever nature, unless caused by or due
to the negligence of Owner, it agents, servants or employees. Owner or its
agents will not be liable for any such damage caused by other tenants or persons
in, upon or about said building or caused by operations in construction of any
private, public or quasi public work. If at any time any windows of the demised
premises are temporarily closed, darkened or bricked up (or permanently closed,
darkened or bricked up, if required by law) for any reason whatsoever including,
but not limited to Owner's own acts, Owner shall not be liable for any damage
Tenant may sustain thereby and Tenant shall not be entitled to any compensation
therefore nor abatement or diminution of rent nor shall the same release Tenant
from its obligations hereunder nor constitute an eviction. Tenant shall
indemnify and save harmless Owner against and from all liabilities, obligations,
damages, penalties, claims, costs and expenses for which Owner shall not be
reimbursed by insurance, including reasonable attorneys fees, paid suffered or
incurred as a result of any breach by Tenant, Tenant's agents, contractors,
employees, invitees, or licensees, of any covenant or condition of this lease,
or the carelessness, negligence or improper conduct of the Tenant, Tenant's
agents, contractors, employees, invitees or licensees. Tenant's liability under
this lease extends to the acts and omissions of any sub-tenant, and any agent,
contractor, employee, invitee or licensee of any sub-tenant. In case any action
or proceeding is brought against Owner by reason of any such claim, Tenant, upon
written notice from Owner, will, at Tenant's expense, resist or defend such
action or proceeding by counsel approved by Owner in writing, such approval not
to be unreasonably withheld.

         Destruction, Fire and Other Casualty: 9. (a) If the demised premises or
any part thereof shall be damaged by fire or other casualty, Tenant shall give
immediate notice thereof to Owner and this lease shall continue in full force
and effect except as hereinafter set forth. (b) If the demised premises are
partially damaged or rendered partially unusable by fire or other casualty, the
damages thereto shall be repaired by and at the expense of Owner and the rent,
until such repair shall be substantially completed, shall be apportioned from
the day following the casualty according to the part of the premises which is
usable. (c) If the demised premises are totally damaged or rendered wholly
unusable by fire or other casualty, then the rent


                                       4
<PAGE>   5
shall be proportionately paid up to the time of the casualty and thenceforth
shall cease until the date when the premises shall have been repaired and
restored by Owner, subject to Owner's right to elect not to restore the same as
hereinafter provided. (d) If the demised premises are rendered wholly unusable
or (whether or not the demised premises are damaged in whole or in part) if the
building shall be so damaged that Owner shall decide to demolish it or to
rebuild it, then, in any of such events, Owner may elect to terminate this lease
by written notice to Tenant, given within 90 days after such fire or casualty,
specifying a date for the expiration of the lease, which date shall not be more
than 60 days after the giving of such notice, and upon the date specified in
such notice the term of this lease shall expire as fully and completely as if
such date were the date set forth above for the termination of this lease and
Tenant shall forthwith quit, surrender and vacate the premises without prejudice
however, to Landlord's rights and remedies against Tenant under the lease
provisions in effect prior to such termination, and any rent owing shall be paid
up to such date and any payments of rent made by Tenant which were on account of
any period subsequent to such date shall be returned to Tenant. Unless Owner
shall serve a termination notice as provided for herein, Owner shall make the
repairs and restorations under the conditions of (b) and (c) hereof, with all
reasonable expedition, subject to delays due to adjustment of insurance claims,
labor troubles and causes beyond Owner's control. After any such casualty,
Tenant shall cooperate with Owner's restoration by removing from the premises as
promptly as reasonably possible, all of Tenant's salvageable inventory and
movable equipment, furniture, and other property. Tenant's liability for rent
shall resume five (5) days after written notice from Owner that the premises are
substantially ready for Tenant's occupancy. (e) Nothing contained hereinabove
shall relieve Tenant from liability that may exist as a result of damage from
fire or other casualty. Notwithstanding the foregoing, each party shall look
first to any insurance in its favor before making any claim against the other
party for recovery for loss or damage resulting from fire or other casualty, and
to the extent that such insurance is in force and collectible and to the extent
permitted bylaw, Owner and Tenant each hereby releases and waives all right of
recovery against the other or any one claiming through or under each of them by
way of subrogation or otherwise. The foregoing release and waiver shall be in
force only if both releasors' insurance policies contain a clause providing that
such a release or waiver shall not invalidate the insurance. If, and to the
extent, that such waiver can be obtained only by the payment of additional
premiums, then the party benefitting from the waiver shall pay such premium
within ten days after written demand or shall be deemed to have agreed that the
party obtaining insurance coverage shall be free of any further obligation under
the provisions hereof with respect to waiver of subrogation. Tenant acknowledges
that Owner will not carry insurance on Tenant's furniture and/or furnishing or
any fixtures or equipment, improvements, or appurtenances removable by Tenant
and agrees that Owner will not be obligated to repair any damage thereto or
replace the same. (f) Tenant hereby waives the provisions of Section 227 of the
Real Property Law and agrees that the provisions of this article shall govern
and control in lieu thereof.

         Eminent Domain: 10. If the whole or any part of the demised premises
shall be acquired or condemned by Eminent Domain for any public or quasi public
use or purpose, then and in that event, the term of this lease shall cease and
terminate from the date of title vesting in such proceeding and Tenant shall
have no claim for the value of any unexpired term of said lease and assigns to
Owner, Tenant's entire interest in any such award.


                                       5
<PAGE>   6
         Assignment, Mortgage, Etc.: 11. Tenant, for itself, its heirs,
distributees, executors, administrators, legal representatives, successors and
assigns, expressly covenants that it shall not assign, mortgage or encumber this
agreement, nor underlet, or suffer or permit the demised premises or any part
thereof to be used by others, without the prior written consent of Owner in each
instance. Transfer of the majority of the stock of a corporate Tenant shall be
deemed an assignment. If this lease be assigned, or if the demised premises or
any part thereof be underlet or occupied by anybody other than Tenant, Owner
may, after default by Tenant, collect rent from the assignee, under-tenant or
occupant, and apply the net amount collected to the rent herein reserved, but no
such assignment, underletting, occupancy or collection shall be deemed a waiver
of this covenant, or the acceptance of the assignee, under-tenant or occupant as
tenant, or a release of Tenant from the further performance by Tenant of
convenants on the part of Tenant herein contained. The consent by Owner to an
assignment or underletting shall not in any wise be construed to relieve Tenant
from obtaining the express consent in writing of Owner to any further assignment
or underletting.

         Electric Current: 12. Rates and conditions in respect to submetering or
rent inclusion, as the case may be, to be added in RIDER attached hereto. Tenant
covenants and agrees that at all times its use of electric current shall not
exceed the capacity of existing feeders to the building or the risers or wiring
installation and Tenant may not use any electrical equipment which, in Owner's
opinion, reasonably exercised, will overload such installations or interfere
with the use thereof by other tenants of the building. The change at any time of
the character of electric service shall in no wise make Owner liable or
responsible to Tenant, for any loss, damages or expenses which Tenant may
sustain.

         Access to Premises: 13. Owner or Owner's agents shall have the right
(but shall not be obligated) to enter the demised premises in any emergency at
any time, and, at other reasonable times, to examine the same and to make such
repairs, replacements and improvements as Owner may deem necessary and
reasonably desirable to the demised premises or to any other portion of the
building or which Owner may elect to perform. Tenant shall permit Owner to use
and maintain and replace pipes and conduits in and through the demised premises
and to erect new pipes and conduits therein provided they are concealed within
the walls, floor, or ceiling. Owner may, during the progress of any work in the
demised premises, take all necessary materials and equipment into said premises
without the same constituting an eviction nor shall the Tenant be entitled to
any abatement of rent while such work is in progress nor to any damages by
reason of loss or interruption of business or otherwise. Throughout the term
hereof Owner shall have the right to enter the demised premises at reasonable
hours for the purpose of showing the same to prospective purchasers or
mortgagees of the building, and during the last six months of the term for the
purpose of showing the same to prospective tenants. If Tenant is not present to
open and permit an entry into the premises, Owner or Owner's agents may enter
the same whenever such entry may be necessary or permissible by master key or
forcibly and provided reasonable care is exercised to safeguard Tenant's
property, such entry shall not render Owner or its agents liable therefore, nor
in any event shall the obligations of Tenant hereunder be affected. If during
the last month of the term Tenant shall have removed all or substantially all of
Tenant's property therefrom Owner may immediately enter, alter, renovate or
redecorate the demised premises without limitation or abatement of rent, or
incurring liability to Tenant for any compensation and such act shall have no
effect on this lease or Tenant's obligations hereunder.


                                       6
<PAGE>   7
         Vault, Vault Space, Area: 14. No Vaults, vault space or area, whether
or not enclosed or covered, not within the property line of the building is
leased hereunder, anything contained in or indicated on any sketch, blue print
or plan, or anything contained elsewhere in this lease to the contrary
notwithstanding. Owner makes no representation as to the location of the
property line of the building. All vaults and vault space and all such areas not
within the property line of the building, which Tenant may be permitted to use
and/or occupy, is to be used and/or occupied under a revocable license, and if
any such license be revoked, or if the amount of such space or area be
diminished or required by any federal, state or municipal authority or public
utility, Owner shall not be subject to any liability nor shall Tenant be
entitled to any compensation of diminution or abatement of rent, nor shall such
revocation, diminution or requisition be deemed constructive or actual eviction.
Any tax, fee or charge of municipal authorities for such vault or area shall be
paid by Tenant.

         Occupancy: 15. Tenant will not at anytime use or occupy the demised
premises in violation of the certificate of occupancy issued for the building of
which the demised premises are a part. Tenant has inspected the premises and
accepts them as is, subject to the riders annexed hereto with respect to Owner's
work, if any.

         Bankruptcy: 16. Anything elsewhere in this lease to the contrary
notwithstanding, this lease may be cancelled by Owner by the sending of a
written notice to Tenant within a reasonable time after the happening of any one
or more of the following events: (1) the commencement of a case in bankruptcy or
under the laws of any state naming Tenant as the debtor; or (2) the making by
Tenant of an assignment or any other arrangement for the benefit of creditors
under any state statute. Neither Tenant nor any person claiming through or under
Tenant, or by reason of any statute or order of court, shall thereafter be
entitled to possession of the premises demised but shall forthwith quit and
surrender the premises. If this lease shall be assigned in accordance with its
terms, the provisions of this Article 16 shall be applicable only to the party
then owning Tenant's interest in this lease.

         (b) it is stipulated and agreed that in the event of the termination of
this lease pursuant to (a) hereof, Owner shall forthwith, notwithstanding any
other provisions of this lease to the contrary, be entitled to recover from
Tenant as and for liquidated damages an amount equal to the difference between
the rent reserved hereunder for the unexpired portion of the term demised and
the fair and reasonable rental value of the demised premises for the same
period. In the computation of such damages the difference between any
installment of rent becoming due hereunder after the date of termination and the
fair and reasonable rental value of the demised premises for the period for
which such installment was payable shall be discounted to the date of
termination at the rate of four percent (4%) per annum. If such premises or any
part thereof, be relet by the Owner for the unexpired term of said lease, or any
part thereof before presentation of proof of such liquidated damages to any
court, commission or tribunal, the amount of rent reserved upon such reletting
shall be deemed to be the fair and reasonable rental value for the part or the
whole of the premises so re-let during the term of the re-letting. Nothing
herein contained shall limit or prejudice the right of the Owner to prove for
and obtain as liquidated damages by reason of such termination, an amount equal
to the maximum allowed by any statute or rule of law in effect at the time when,
and governing the proceedings in which, such damages are to be proved, whether
or not such amount be greater, equal to, or less than the amount of the
difference referred to above.


                                       7
<PAGE>   8
         Default: 17. (1) If Tenant defaults in fulfilling any of the covenants
of this lease other than the covenants for payment of rent or additional rent;
or if the demised premises become vacant or deserted; or if any execution or
attachment shall be issued against Tenant or any of Tenant's property whereupon
the demised premises shall be taken or occupied by someone other than Tenant; or
if this lease be rejected under Section 235 of Title 11 of the U.S. Code
(bankruptcy code); or then, in any one or more of such events, upon Owner
serving a written 21 day notice upon Tenant specifying the nature of said
default and upon the expiration of said 21 days, if Tenant shall have failed to
comply with or remedy such default, or if the said default or omission
complained of shall be of a nature that the same cannot be completely cured or
remedied within said 21 day period, and if Tenant shall not have diligently
commenced curing such default within such 21 day period, and shall not
thereafter with reasonable diligence and in good faith, proceed to remedy or
cure such default, then Owner may serve a written three (3) days' notice of
cancellation of this lease upon Tenant, and upon the expiration of said three
(3) days this lease and the term thereunder shall end and expire as fully and
completely as if the expiration of such three (3) day period were the day herein
definitely fixed for the end and expiration of this lease and the term thereof
and Tenant shall then quit and surrender the demised premises to Owner but
Tenant shall remain liable as hereinafter provided.

                  (2) If the notice provided for in (1) hereof shall have been
given, and the term shall expire as aforesaid; or if Tenant shall make default
in the payment of the rent reserved herein or any item of additional rent herein
mentioned or any part of either or in making any other payment herein required;
then and in any of such events Owner may without notice, re-enter the demised
premises either by force or otherwise, and dispossess Tenant by summary
proceeding or otherwise, and the legal representative of Tenant or other
occupant of demised premises and remove their effects and hold the premises as
if this lease had not been made, and Tenant hereby waives the service of notice
of intention to re-enter or to institute legal proceedings to that end. If
Tenant shall make default hereunder prior to the date fixed as the commencement
of any renewal or extension of this lease, Owner may cancel and terminate such
renewal or extension agreement by written notice.

                  Remedies of Owner and Waiver of Redemption: 18. In case of any
such default, re-entry, expiration and/or dispossess by summary proceedings or
otherwise, (a) the rent shall become due thereupon and be paid up to the time of
such re-entry, dispossess and/or expiration, (b) Owner may re-let the premises
or any part or parts thereof, either in the name of Owner or otherwise, for a
term or terms, which may at Owner's option be less than or exceed the period
which would otherwise have constituted the balance of the term of this lease and
may grant concessions or free rent or charge a higher rental than that in this
lease, and/or (c) Tenant or the legal representatives of Tenant shall also pay
Owner as liquidated damages for the failure of Tenant to observe and perform
said Tenant's covenants herein contained, any deficiency between the rent hereby
reserved and/or covenanted to be paid and the net amount, if any, of the rents
collected on account of the lease or leases of the demised premises for each
month of the period which would otherwise have constituted the balance of the
term of this lease. The failure of Owner to re-let the premises or any part or
parts thereof shall not release or affect Tenant's liability for damages. In
computing such liquidated damages there shall be added to the said deficiency
such expenses as Owner may incur in connection with re-letting, such as legal
expenses, attorneys' fees, brokerage, advertising and for keeping the demised
premises in good order or for preparing the same for re-letting. Any such
liquidated damages shall be paid in



                                       8
<PAGE>   9
monthly installments by Tenant on the rent day specified in this lease and any
suit brought to collect the amount of the deficiency for any month shall not
prejudice in any way the rights of Owner to collect the deficiency for any
subsequent month by a similar proceeding. Owner, in putting the demised premises
in good order or preparing the same for re-rental may, at Owner" option, make
such alterations, repairs, replacements, and/or decorations in the demised
premises as Owner, in Owner" sole judgement, considers advisable and necessary
for the purpose of re-letting the demised premises, and the making of such
alterations, repairs, replacements, and/or decorations shall not operate or be
construed to release Tenant from liability hereunder as aforesaid. Owner shall
in no event be liable in any way whatsoever for failure to re-let the demised
premises, or in the event that the demised premises are re-let, for failure to
collect the rent thereof under such re-letting, and in no event shall Tenant be
entitled to receive any excess, if any, of such net rents collected over the
sums payable by Tenant to Owner hereunder. In the event of a breach or
threatened breach by Tenant of any of the covenants or provisions hereof, Owner
shall have the right of injunction and the right to invoke any remedy allowed at
law or inequity as if re-entry, summary proceedings and other remedies were not
herein provided for. Mention in this lease of any particular remedy, shall not
preclude Owner from any other remedy, in law or in equity. Tenant hereby
expressly waives any and all rights of redemption granted by or under any
present or future laws in the event of Tenant being evicted or dispossessed for
any cause, or in the event of Owner obtaining possession of demised premises, by
reason of the violation by Tenant of any of the covenants and conditions of this
lease, or otherwise.

                  Fees and Expenses 19. If Tenant shall default in the
observance or performance of any term or covenant on Tenant's part to be
observed or performed under or by virtue of any of the terms or provisions in
any article of this lease, then, unless otherwise provided elsewhere in this
lease, Owner may immediately or at any time thereafter and without notice
perform the obligation of Tenant thereunder. If Owner, in connection with the
foregoing or in connection with any default by Tenant in the covenant to pay
rent hereunder, makes any expenditures or incurs any obligations for the payment
of money, including but not limited to attorney's fees, in instituting,
prosecuting or defending any action or proceeding, then Tenant will reimburse
Owner for such sums so paid or obligations incurred with interest and costs. The
foregoing expenses incurred by reason of Tenant's default shall be deemed to be
additional rent hereunder and shall be paid by Tenant to Owner within five (5)
days of rendition of any bill or statement to Tenant therefor. If Tenant's lease
term shall have expired at the time of making of such expenditures or incurring
of such obligations, such sums shall be recoverable by Owner as damages.

                  Building Alterations and Management: 20. Owner shall have the
right at anytime without the same constituting an eviction and without incurring
liability to Tenant therefore to change the arrangement and/or location of
public entrances, passageways, doors, doorways, corridors, elevators, stairs,
toilets or other public parts of the building and to change the name, number or
designation by which the building may be known. There shall be no allowance to
Tenant for diminution of rental value and no liability on the part of Owner by
reason of inconvenience, annoyance or injury to business arising from Owner or
other Tenants making any repairs in the building or any such alterations,
additions and improvements. Furthermore, Tenant shall not have any claim against
Owner by reason of Owner's imposition of such controls of the manner of access
to the building by Tenant's social or business visitors as the Owner may deem
necessary for the security of the building and its occupants.

<PAGE>   10
                  No Representations by Owner: 21. Except as otherwise provided
for herein neither Owner nor Owner's agents have made any representations or
promises with respect to the physical condition of the building, the land upon
which it is erected or the demised premises, the rents, leases, expenses of
operation or any other matter or thing affecting or related to the premises
except as herein expressly set forth and no rights, easements or licenses are
acquired by Tenant by implication or otherwise except as expressly set forth in
the provisions of this lease. Tenant has inspected the building and the demised
premises and is thoroughly acquainted with their condition and agrees to take
the same "as is" and acknowledges that the taking of possession of the demised
premises by Tenant shall be conclusive evidence that the said premises and the
building of which the same form a part were in good and satisfactory condition
at the time such possession was so taken, except as to latent defects. All
understandings and agreements heretofore made between the parties hereto are
merged in this contract, which alone fully and completely expresses the
agreement between Owner and Tenant and any executory agreement hereafter made
shall be ineffective to change, modify, discharge or effect an abandonment of it
in whole or in part, unless such executory agreement is in writing and signed by
the party against whom enforcement of the change, modification, discharge or
abandonment is sought.

                  End of Term 22. Upon the expiration or other termination of
the term of this lease, Tenant shall quit and surrender to Owner the demised
premises, broom clean, in good order and condition, ordinary wear and damages
which Tenant is not required to repair as provided elsewhere in this lease
excepted, and Tenant shall remove all its property. Tenant's obligation to
observe or perform this covenant shall survive the expiration or other
termination of this lease. If the last day of the term of this Lease or any
renewal thereof, falls on Sunday, this lease shall expire at noon on the
preceding Saturday unless it be a legal holiday in which case it shall expire at
noon on the preceding business day.

                  Quiet Enjoyment: 23. Owner covenants and agrees with Tenant
that upon Tenant paying the rent and additional rent and observing and
performing all the terms, covenants and conditions, on Tenant's part to be
observed and performed, Tenant may peaceably and quietly enjoy the premises
hereby demised, subject, nevertheless, to the terms and conditions of this lease
including, but not limited to, Article 31 hereof and to the ground leases,
underlying leases and mortgages hereinbefore mentioned.

                  Failure to Give Possession: 24. If Owner is unable to give
possession of the demised premises on the date of the commencement of the term
hereof, because of the holding-over or retention of possession of any tenant,
undertenant or occupants or if the demised premises are located in a building
being constructed, because such building has not been sufficiently completed to
make the premises ready for occupancy or because of the fact that a certificate
of occupancy has not been precured or for any other reason, Owner shall not be
subject to any liability for failure to give possession on said date and the
validity of the lease shall not be impaired under such circumstances, nor shall
the same be construed in any wise to extend the term of this lease, but the rent
payable hereunder shall be abated (provided Tenant is not responsible for
Owner's inability to obtain possession) until after Owner shall have given
Tenant written notice that the premises are substantially ready for Tenant's
occupancy. If permission is given to Tenant to enter into the demised premises
prior to the date specified as the commencement of the term of this lease,
Tenant covenants and agrees that such occupancy shall


                                       10
<PAGE>   11
be deemed to be under all the terms, covenants, conditions and provisions of
this lease except as to the covenant to pay rent. The provisions of this article
are intended to constitute "an express provision to the contrary" within the
meaning of Section 223-a of the New York Real Property Law.

                  No Waiver: 25. The failure of a party to seek redress for
violation of, or to insist upon the strict performance of any covenant or
condition of this lease or of any of the Rules or Regulations, set forth or
hereafter adopted by Owner, shall not prevent a subsequent act which would have
originally constituted a violation from having all the force and effect of an
original violation. The receipt by Owner of rent with knowledge of the breach of
any covenant of this lease shall not be deemed a waiver of such breach and no
provision of this lease shall be deemed to have been waived by Owner unless such
waiver be in writing signed by Owner. No payment by Tenant or receipt by Owner
of a lesser amount than the monthly rent herein stipulated shall be deemed to be
other than on account of the earliest stipulated rent, nor shall any endorsement
or statement of any check or any letter accompanying any check or payment as
rent be deemed an accord and satisfaction, and Owner may accept such check or
payment without prejudice to Owner's right to recover the balance of such rent
or pursue any other remedy in this lease provided. No act or thing done by Owner
or Owner's agents during the term hereby demised shall be deemed an acceptance
of a surrender of said premises, and no agreement to accept such surrender shall
be valid unless in writing signed by Owner. No employee of Owner or Owner's
agent shall have any power to accept the keys of said premises prior to the
termination of the lease and the delivery of keys to any such agent or employee
shall not operate as a termination of the lease or a surrender of the premises.
See paragraph 65(b).

                  Waiver of Trial by Jury: 26. It is mutually agreed by and
between Owner and Tenant that the respective parties hereto shall and they
hereby do waive trial by jury in any action, proceeding or counter-claim brought
by either of the parties hereto against the other (except for personal injury or
property damage) on any matters whatsoever arising out of or in any way
connected with this lease, the relationship of Owner and Tenant, Tenant's use of
or occupancy of said premises, and any emergency statutory or any other
statutory remedy. It is further mutually agreed that in the event Owner
commences any summary proceeding for possession of the premises, Tenant will not
interpose any counterclaim of whatever nature or description in any such
proceeding including a counterclaim under Article 4.

                  Inability to Perform 27. This Lease and the obligation of
Tenant to pay rent hereunder and perform all of the other covenants and
agreements hereunder on part of Tenant to be performed shall in no wise be
affected, impaired or excused because Owner is unable to fulfill any of its
obligations under this lease or to supply or is delayed in supplying any service
expressly or impliedly to be supplied or is unable to make, or is delayed in
making any repair, additions, alterations or decorations or is unable to supply
or is delayed in supplying any equipment or fixtures if Owner is prevented or
delayed from so doing by reason of strike or labor troubles or any cause
whatsoever including, but not limited to, government preemption in connection
with a National Emergency or by reason of any rule, order or regulation of any
department or subdivision thereof of any government agency or by reason of the
conditions of supply and demand which have been or are affected by war or other
emergency.

provided, a bill, statement, notice or communication which Owner may desire or
be required to give to Tenant, shall be deemed sufficiently given or rendered
if, in writing, delivered to Tenant personally or sent by registered or
certified mail addressed to Tenant at the building of which the demised premises
form a part or at the last known residence address or business address of Tenant
or left at any of the aforesaid premises addressed to Tenant, and the time of
the rendition of such bill or statement and of the giving of such notice or
communication shall be deemed to be the time when the same is delivered to
Tenant, mailed, or left at the premises as herein provided. Any notice by Tenant
to Owner must be served by registered or certified mail addressed to Owner at
the address first hereinabove given or at such other address as Owner shall
designate by written notice.

necessary elevator facilities on business days from 8 a.m. to 6 p.m. and on
Saturdays from 8 a.m. to 1 p.m. and have one elevator subject to call at all

any other purposes or in unusual quantities (of which fact Owner shall be the

to register such water consumption and Tenant shall pay for water consumed as
shown on said meter as additional rent as and when bills are rendered; (d)

provided that the same are kept in order by Tenant. If, however, said premises

shall be permitted to enter said premises or the building of which they are a
part for such purpose. Tenant shall pay Owner the cost of removal of any of

aforesaid hours except when air conditioning/cooling is being furnished as

services of the heating, elevators, plumbing, air-conditioning, power systems or
cleaning or other services, if any, when necessary by reason of accident or for
repairs, alterations, replacements or improvements necessary or desirable in the
judgement of Owner for as long as may be reasonable required by reason thereof.
If the building of which the demised premises are a part supplies
manually-operated elevator service, Owner at any time may substitute
automatic-control elevator service and upon ten days' written notice to Tenant,
proceed with alterations necessary therefore without in any wise affecting this
lease or the obligation of Tenant hereunder. The same shall be done with a
minimum of inconvenience to Tenant and Owner shall pursue the alteration with
due diligence.

expense which tenant may sustain or incur if either the quantity or character of

requirements as a result of causes beyond landlord's reasonable control. Any
riser or risers to supply Tenant's electrical requirements, upon written request
of Tenant, and written approval of Landlord may be installed by Tenant, at the
sole cost and expense of Tenant, if, in landlord's sole reasonable judgement,

event that such bills are not paid within five (5) business days after they are
rendered, Landlord may, after five (5) business days written notice to Tenant in
accordance with paragraph 59, discontinue the service electric current to the
demised premises. Since landlord is liable to Con Edison for payment of the
bills even in the event tenant defaults, landlord's election to employ this
remedy shall not be considered a breach of agreement and shall not entitle
tenant to any offset of rent.

             Landlord may also discontinue service of electric current to the
demised premises without cause upon thirty (30) days notice to Tenant, however,
in such event, Landlord will continue to supply electric service until tenant

and other appropriate wiring to insure that tenant's electrical service is not
interrupted.

this Lease. Such discontinuance shall not be deemed to be a lessening of
services within the meaning of any law, rule, or regulation now or hereafter
enacted, promulgated or issued. In the event of such discontinuance, tenant
shall arrange to receive such service directly from said public utility
corporation.

be unreasonably withheld and/or delayed, same shall be deemed an unauthorized
assignment. However, it is understood and agreed that in the event Landlord
consents to any such assignment, sublet of transfer same shall not diminish
tenant's obligation to perform all the terms, warranties, and covenants. Such

brokerage commissions legal fees and the cost of tenant's leasehold
improvements. Such excess shall be determined by dividing the rent (base and
additional) paid by tenant by the number of square feet of the demised premises
in order to determine a rent per square foot. If the rent per square foot
pursuant to the sublease or lease assignment exceeds the rent per square foot
pursuant to this Lease less the aforementioned expenses, Landlord shall be
entitled to one-half (1/2) if such excess.

partner, affiliated company or other alter-ego of Tenant, Tenant shall remain

premises free of any violations that may be imposed by the Department of

demand, as provided for hereinabove, it is understood and agreed that Landlord
shall be entitled to interest calculated at a daily periodic rate of .0411, an

agents and employees and all such persons shall use their best efforts not to
unreasonably interfere with the conduct of Tenant's business and Tenant's
occupancy of the demised premises. Tenant's failure to comply with this
provision shall be deemed a substantial breach of this Lease and sufficient
grounds for the summary termination of this Lease. Landlord agrees that except
in the event of an emergency requiring immediate entry, it will give Tenant
reasonable notice if Landlord desires to inspect or otherwise gain access to the
demised premises, provided that Tenant shall receive reasonable advance notice
thereof and that Landlord and its agents and employees and all such persons
shall use their best efforts not to unreasonably interfere with the conduct of
Tenant's business and Tenant's occupancy of the demised premises.

with access as provided for hereinabove and in the event Landlord, in its sole
