                   SUBJECT TO COMPLETION, DATED MAY 20, 1998

                   5% CONVERTIBLE SUBORDINATED NOTES DUE 2006

     (AND THE SHARES OF COMMON STOCK ISSUABLE UPON CONVERSION OF THE NOTES)

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

         We issued $150,000,000 of notes in a private placement in March 1999.
This prospectus will be used by selling security holders to resell their notes
and the common stock issuable upon conversion of their notes.

         The notes are convertible at any time prior to maturity into common
stock, at an initial conversion rate of 15.355 shares of common stock per
$1,000 principal amount of notes which is equivalent to a conversion price of
approximately $65.125 per share, subject to adjustment in certain events. Our
common stock is quoted on the Nasdaq National Market under the symbol "SPLN."
On May 19, 1999, the closing price of our common stock was $34.00 per share.

         We will pay interest on the notes on April 1 and October 1 of each
year, beginning on October 1, 1999, at a rate of 5% per year. The notes will
mature on April 1, 2006 unless earlier converted or redeemed. The notes are
unsecured and are subordinated to our existing and future senior indebtedness.
As of March 31, 1999, we had no material indebtedness other than the notes.

         We may redeem the notes after April 2, 2002, at the declining
redemption prices listed in this prospectus, plus accrued interest. In
addition, if a repurchase event occurs, we must offer to repurchase the notes.

         We will not receive any proceeds from the sale by the selling security
holders of the notes or the common stock into which the notes are convertible.
We will pay all expenses of the registration of the notes and the common stock
other than selling commissions and fees and stock transfer taxes.

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

         SEE "RISK FACTORS" BEGINNING ON PAGE 5 FOR A DESCRIPTION OF CERTAIN
MATTERS THAT YOU SHOULD CONSIDER BEFORE INVESTING IN THE NOTES OR THE COMMON
STOCK INTO WHICH THE NOTES ARE CONVERTIBLE.

SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR

                             ABOUT THIS PROSPECTUS

      This prospectus is part of a registration statement that we filed with
the Securities and Exchange Commission utilizing a "shelf" registration
process. Under this shelf process, the selling security holders may sell up to
$150,000,000 aggregate principal amount of the notes or the applicable number
of shares of common stock which are issuable upon conversion of the notes. This
prospectus provides you with a general description of the notes and the common
stock into which the notes are convertible that the selling security holders
may offer. When the selling security holders sell the notes or the common
stock, we may provide, if necessary, a prospectus supplement that will contain
specific terms of that offering. The prospectus supplement may also add, update
or change information contained in this prospectus. You should read this
prospectus and any prospectus supplement together with the additional
information described under the heading "Where You Can Find More Information."

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

      This prospectus contains or incorporates by reference statements about
our future that are "forward-looking statements" within the meaning of the
Private Securities Litigation Reform Act of 1995. This act provides a "safe
harbor" for forward-looking statements to encourage companies to provide
prospective information about themselves so long as they identify these
statements as forward-looking and provide meaningful cautionary statements
identifying important factors that could cause actual results to differ from
the projected results. All statements other than statements of historical fact
we make in this prospectus or any other document incorporated by reference are
forward-looking. In some cases, you can identify these forward-looking
statements by terminology such as "believes," "expects," "may," "will,"
"should," "seeks," "approximately," "intends," "plans," "estimates," or
"anticipates" or the negative of those words or other comparable terminology.
In evaluating these statements, you should specifically consider various
factors, including the risks outlined under the caption "Risk Factors" in this
prospectus. You should pay particular attention to the cautionary statements
involving our limited operating history, the unpredictability of our future
revenues, the unpredictable and evolving nature of our business model, the
intensely competitive market for Internet services and products and the risks
associated with capacity constraints, systems development, management of
growth, acquisitions and international and domestic business expansion. These
factors may cause our actual results to differ materially and adversely from
any forward-looking statement.

                                                    business on the final maturity date of the notes, unless the

                                  RISK FACTORS

      You should carefully consider the following factors and other information
included or incorporated by reference in this prospectus before investing in
the notes or common stock.

WE HAVE ONLY BEEN OPERATING OUR BUSINESS SINCE AUGUST 1995

      We were incorporated in February 1994 and commercially introduced our
first Web site in August 1995. We first recognized revenue from operations in
the quarter ended September 30, 1995. Accordingly, we have a limited operating
history upon which you may evaluate us. You should consider our prospects in
light of the risks, expenses and difficulties frequently encountered by early
stage companies in new and rapidly evolving markets, including the
Internet-based advertising, information services and commerce markets. As an
early stage online content provider and commerce company, we have an evolving
and unpredictable business model, we face intense competition, we must
effectively manage our growth and we must respond quickly to rapid changes in
customer demands and industry standards. To address these risks, we must
provide compelling and original content to our users, we must maintain our
existing relationships and effectively develop new relationships with
advertisers, advertising agencies and other third parties, we must develop and
upgrade our technology and respond to competitive developments, and we must
attract, retain and motivate qualified personnel. We may not succeed in
addressing these challenges and risks.

WE HAVE AN ACCUMULATED DEFICIT AND WE ANTICIPATE FURTHER LOSSES

      We have incurred significant losses since we began doing business. To
date, we have achieved only limited revenue and our ability to generate
significant revenue is subject to substantial uncertainty. We may not ever
generate sufficient revenue to meet our expenses or achieve or maintain
profitability. We incurred net losses of $16.1 million during 1996, $34.2
million during 1997, $35.5 million during 1998, and $10.1 million during the
first quarter of 1999. As of March 31, 1999, we had an accumulated deficit of
$102.4 million. We expect to continue to incur losses for at least the next 24
to 36 months.

      Since inception, we have incurred substantial costs to develop and
enhance our technology, to create, introduce and enhance our service offerings,
to acquire and develop content, to build traffic on our Web sites, to acquire
members, to establish marketing relationships and to build an administrative
organization. We intend to continue these efforts and we plan to increase our
spending for marketing and for the development and acquisition of content. We
have entered into various licensing, royalty and consulting agreements with
content providers, vendors, athletes and sports organizations, which agreements
provide for consideration in various forms, including issuance of warrants to
purchase shares of our common stock and payment of royalties, bounties and
certain other guaranteed amounts on a per member and/or a minimum dollar amount
basis over terms ranging from one to ten years. Additionally, some of these
agreements provide for a specified percentage of advertising and merchandising
revenue to be paid to the athlete or organization from whose Web site the
revenue is derived. As of March 31, 1999, the minimum guaranteed payments we
were required to make under such agreements were $6,076,000. Our minimum
guaranteed payments are subject to reduction in the case of certain agreements
based upon the appreciation of warrants issued, the value of stock received on
exercise of such warrants and the amount of profit sharing earned under the
related agreements. Also, we recorded non-cash expense of $12,000,000 for the
year ended December 31, 1998 related to our agreement with CBS and will record
an additional $160,098,000 of non-cash expense over the remaining eight-year
term of our agreement with CBS. Additionally, non-cash expense under our
agreement with AOL will total $21,906,000 over the remaining term of that
agreement.

OUR QUARTERLY RESULTS MAY FLUCTUATE AND OUR FUTURE REVENUES ARE UNPREDICTABLE
AND MAY BE SEASONAL

      Due to our limited operating history and the unpredictability of our
industry, we cannot accurately forecast our revenue. Our revenues for the
foreseeable future will continue to come from a mix of advertising, merchandise
sales, membership and premium service fees, content licensing, Web site
development and syndication fees. We are likely to experience fluctuations in
quarterly revenue and operating results due to the level of advertising revenue
within each quarter. We base our current and future expense levels on our
investment plans and estimates of future revenues. Our expenses are to a large
extent fixed. We may not be able to adjust our spending quickly if our revenues
fall short of our expectations.






                                       5
<PAGE>   7

      Our revenues and operating results may vary significantly from quarter to
quarter due to a number of factors, including:

      o     the level of usage of the Internet,

      o     the level of traffic on our Web sites,

      o     demand for Internet advertising,

      o     seasonal trends in both Internet usage and advertising placements,

      o     the addition or loss of advertisers,

      o     the advertising budgeting cycles of individual advertisers,

      o     the number of users that purchase memberships, merchandise or
            premium services,

      o     the amount and timing of capital expenditures and other costs
            relating to the expansion of our operations,

      o     the introduction of new sites and services by us or our
            competitors,

      o     price competition or pricing changes in the industry, and

      o     general economic conditions and economic conditions specific to the
            Internet, electronic commerce and online media.

      Furthermore, we expect that our revenue will be higher leading up to and
during major U.S. sports seasons and lower at other times of the year,
particularly during the summer months. In addition, the effect of such seasonal
fluctuations in revenue could be enhanced or offset by revenue associated with
major sports events, such as the Olympics and World Cup events, although such
events do not occur every year. We believe that advertising sales in
traditional media, such as television, generally are lower in the first and
third calendar quarters of each year, and that advertising expenditures
fluctuate significantly with economic cycles. Depending on the extent to which
the Internet is accepted as an advertising medium, seasonality and cyclicality
in the level of Internet advertising expenditures could become more pronounced
in which case our revenues may be affected by such seasonal and cyclical
patterns.

         Due to all of the foregoing factors, we believe that
quarter-to-quarter comparisons of our operating results are not a good
indication of our future performance. It is possible that our operating results
may fall below the expectations of securities analysts or investors in some
future quarter which would likely cause the trading price of the notes and our
common stock to decline.

WE ARE DEPENDENT UPON OUR RELATIONSHIP WITH CBS TO EXECUTE OUR BUSINESS PLAN

      In March 1997, we entered into a five-year agreement with CBS, pursuant
to which our flagship Web site was renamed "cbs.sportsline.com." We amended our
agreement with CBS in February 1999 to extend the term through 2006. Over the
term of the agreement, we have the right to use certain CBS logos and
television-related sports content and will receive extensive network television
advertising and on-air promotions. This network television advertising and
on-air promotions, as well as the association of our brand with CBS, are
important elements of our strategy to increase awareness of the SportsLine
brand and build traffic on our Web sites. Under the agreement, CBS has the
right to receive specified percentages of our net revenues. The agreement
requires us to maintain and operate our flagship Web site, cbs.sportsline.com,
in accordance with certain guidelines and restrictions and to cease using any
content on cbs.sportsline.com which CBS determines conflicts, interferes with
or is detrimental to CBS's reputation or business or which becomes subject to
any third party restriction or claim which would prohibit, limit or restrict
the use of such content on the Internet. CBS has the right to terminate the
agreement upon the acquisition by a CBS competitor of 40% or more of the voting
power of our equity securities or in certain other circumstances, including if
we breach a material term or condition or the agreement or if we become
insolvent or subject to bankruptcy or similar proceedings.






                                       6
<PAGE>   8

      We cannot assure you that CBS will perform its obligations under the
agreement, or that the agreement will significantly increase consumer awareness
of our brand or build traffic on our Web sites. Any failure of CBS to perform
its material obligations under the agreement, or the termination of the
agreement prior to the end of its term, would have a material adverse effect on
our business, results of operations and financial condition.

WE RELY ON OTHER STRATEGIC RELATIONSHIPS IN ORDER TO EXECUTE OUR BUSINESS PLAN

      In addition to our relationship with CBS, we have entered into other
strategic relationships with sports superstars and personalities, sports
organizations, commercial online services (such as AOL), third party Web sites
(such as Excite, Netscape and InfoSpace) and developers of browsers and other
Internet-based products. We rely on these relationships to increase awareness
of our brand among consumers, to create revenue opportunities and to obtain
content for our Web sites. We cannot assure you that a party to any of our
strategic agreements will perform its obligations as agreed or that we will be
able to specifically enforce any such agreement. Many of the these strategic
agreements are short-term in nature and certain of these agreements may be
terminated by either party on short notice. Our failure to maintain or renew
these existing strategic relationships, to establish additional strategic
relationships or to fully capitalize on any such relationship could have a
material adverse effect on our business, results of operations and financial
condition.

WE MAY NOT BE ABLE TO COMPETE SUCCESSFULLY

      The market for Internet services and products is relatively new,
intensely competitive and rapidly changing. Since the Internet's
commercialization in the early 1990's, the number of Web sites on the Internet
competing for consumers' attention and spending has proliferated with no
substantial barriers to entry, and we expect that competition will continue to
intensify. Competition could result in less user traffic to our Web sites,
price reductions for our advertising, reduced margins or loss of market share,
any of which would have a material adverse effect on our business, results of
operations and financial condition.

      We compete for advertisers, viewers, members, content providers,
merchandise sales and rights to sports events with the following categories of
companies:

      o     online services or Web sites targeted to sports enthusiasts
            generally (such as ESPN.com, CNN and Sports Illustrated's CNN/SI
            and Fox Sports) or to enthusiasts of particular sports (such as Web
            sites maintained by Major League Baseball, the NFL, the NBA and the
            NHL),

      o     publishers and distributors of traditional off-line media (such as
            television, radio and print), including those targeted to sports
            enthusiasts, many of which have established or may establish Web
            sites,

      o     general purpose consumer online services such as AOL and Microsoft
            Network, each of which provides access to sports-related content
            and services,

      o     vendors of sports information, merchandise, products and services
            distributed through other means, including retail stores, mail,
            facsimile and private bulletin board services, and

      o     Web search and retrieval services and portals, such as AltaVista,
            Excite, InfoSeek, Lycos, Netscape and Yahoo!, and other
            high-traffic Web sites.

      Our ability to compete depends on many factors, many of which are outside
of our control. These factors include the quality of content provided by us and
by our competitors, the ease of use of services developed either by us or by
our competitors, the timing and market acceptance of new and enhanced services
developed either by us or by our competitors, and sales and marketing efforts
by us and our competitors.

      Based on our review of publicly available documents, we believe some of
our existing competitors, as well as potential new competitors, have longer
operating histories, significantly greater financial, technical and marketing
resources, greater name recognition and substantially larger user or membership
bases than we do. This may allow them to devote greater resources than we can
to the development and promotion of their services. In addition, some of these
competitors may be able to respond more quickly than us to new or emerging
technologies and changes in Internet user requirements and to devote greater
resources than us to the development, promotion and sale of their services.
There can be no assurance that our current or potential competitors will not
develop products and services comparable or superior to those developed by us
or adapt more quickly than us to new technologies, evolving industry trends or
changing Internet user preferences. In addition, as we expand internationally
we are likely to face new competition. There can be no assurance that we will
be able to compete successfully against current and future competitors, or that
competitive pressures would not have a material adverse effect on our business,
results of operations and financial condition.






                                       7
<PAGE>   9

WE ARE DEPENDENT ON CERTAIN CONTENT PROVIDERS AND ARE REQUIRED TO MAKE
SIGNIFICANT PAYMENTS TO SUCH CONTENT PROVIDERS

      We rely on independent content providers for sports news, scores,
statistics and other sports information. Our future success depends, in
significant part, on our ability to maintain and renew our relationships with
these content providers and to build new relationships with other content
providers. Our agreements with content providers generally are short-term and
may be terminated by the content provider if we fail to fulfill our obligations
under the applicable agreement. Some of our content providers compete with one
another and, to some extent, with us for advertising and members. Termination
of one or more significant content provider agreements would decrease the
availability of sports news and information which we can offer our customers
and could have a material adverse effect on our business, results of operations
and financial condition.

      Most of our agreements with content providers are nonexclusive, and many
of our competitors offer, or could offer, content that is similar or the same
as that obtained by us from such content providers. In addition, the growing
reach and use of the Internet have further intensified competition in this
industry. Consumers have gained free access to certain information provided
directly on the Internet by certain content providers. To the extent that
content providers, including but not limited to our current suppliers, provide
information to users at a lower cost than us or at minimal or no cost, our
business, results of operations and financial condition could be materially
adversely affected.

      Fees payable to content providers constitute a significant portion of our
cost of revenue. There can be no assurance that these content providers will
enter into or renew agreements with us on the same or similar terms as those
currently in effect. If we are required to increase the fees payable to our
content providers, such increased payments could have a material adverse effect
on our business, results of operations and financial condition.

EFFECTIVELY MANAGING OUR GROWTH MAY BE DIFFICULT

      We have rapidly and significantly expanded our operations and anticipate
that significant expansion of our operations will continue to be required in
order to address potential market opportunities. This growth is likely to place
a significant strain on our management, operational and financial resources and
systems. To manage our growth, we must implement systems and train and manage
our employees. In addition, it may become necessary to increase the capacity of
our software, hardware and telecommunications systems on short notice. We
cannot assure you that our management will be able to effectively or
successfully manage our growth.

OUR ACQUISITION STRATEGY HAS CERTAIN RISKS

      Our acquisition strategy is subject to the following risks:

      o     we may not be able to identify additional suitable acquisition
            candidates available for sale at reasonable prices,

      o     acquisitions may cause a disruption in our ongoing business,
            distract our management and other resources and make it difficult
            to maintain our standards, controls and procedures,

      o     we may not be able to consummate any acquisition or successfully
            integrate services, products and personnel of any acquisition into
            our operations,

      o     we may acquire companies in markets in which we have little
            experience, and

      o     we may be required to incur debt or issue equity securities, which
            may be dilutive to existing shareholders, to pay for acquisitions.







                                       8
<PAGE>   10

OUR STRATEGY TO EXPAND INTERNATIONALLY HAS CERTAIN RISKS

      We plan to continue to expand our business internationally and expect
that our international operations will be subject to most of the risks inherent
in our business generally. We can not assure you that revenue from
international operations will increase in the future or that operating losses
will not be incurred from such operations. In addition, there are certain risks
inherent in doing business in international markets, such as:

      o     changes in regulatory requirements, tariffs and other trade
            barriers,

      o     fluctuations in currency exchange rates,

      o     potentially adverse tax consequences,

      o     difficulties in managing or overseeing foreign operations, and

      o     differences in consumer preferences and requirements in different
            markets.

WE MAY NOT BE ABLE TO PROTECT OUR PROPRIETARY RIGHTS AND WE MAY INFRINGE THE
PROPRIETARY RIGHTS OF OTHERS

      Proprietary rights are important to our success and competitive position.
In 1996, we were issued a United States trademark registration for our former
SportsLine USA logo. We have applied to register in the United States our
current SportsLine USA logo and a number of other marks, several of which
include the term "SportsLine USA." We have filed applications to register
"SportsLine" marks in Australia, the United Kingdom and other countries. We can
not assure you that we will be able to secure adequate protection for these
trademarks in the United States or in foreign countries. Although we seek to
protect our proprietary rights, our actions may be inadequate to protect any
trademarks and other proprietary rights or to prevent others from claiming
violations of their trademarks and other proprietary rights. In addition,
effective copyright and trademark protection may be unenforceable or limited in
certain countries, and the global nature of the Internet makes it impossible to
control the ultimate destination of our work. We also license content from
third parties and it is possible that we could become subject to infringement
actions based upon the content licensed from those third parties. We generally
obtain representations as to the origin and ownership of such licensed content;
however, this may not adequately protect us. Any of these claims, with or
without merit, could subject us to costly litigation and divert the attention
of our technical and management personnel.

OUR BUSINESS IS AT RISK OF SYSTEM FAILURES, DELAYS AND INADEQUACY

      The performance of our Web sites is critical to our reputation and
ability to attract and retain users, advertisers and members. Services based on
sophisticated software and computer systems often encounter development delays
and the underlying software may contain undetected errors or failures when
introduced. Any system error or failure that causes interruption in
availability or an increase in response time could result in a loss of
potential or existing users, advertisers or members and, if sustained or
repeated, could reduce the attractiveness of our Web sites to users and
advertisers. A sudden and significant increase in the number of users of our
Web sites also could strain the capacity of the software, hardware or
telecommunications systems we deploy, which could lead to slower response time
or system failures. In addition, if the number of Web pages or users of our Web
sites increases substantially, our hardware and software infrastructure may not
be able to adequately handle the increased demand. Our operations also are
dependent upon receipt of timely feeds and computer downloads from content
providers, and any failure or delay in the transmission or receipt of such
feeds and downloads, whether on account of our system failure, our content
providers, the public network or otherwise, could disrupt our operations. Any
failure or delay that causes interruptions in our operations could have a
material adverse effect on our business, results of operations and financial
condition.

OUR SUCCESS IS DEPENDENT ON OUR KEY PERSONNEL

      Our future success depends, in part, upon the continued service of our
senior management and other key personnel. Although we are the beneficiary of a
key man life insurance policy covering Michael Levy, SportsLine USA's President
and Chief Executive Officer, and in June 1998 we entered into an employment
agreement with Mr. Levy which continues in effect through December 31, 2003,
the loss of his services or the services of one or more of our other executive
officers or key employees could have a material adverse effect on our business,
results of operations and financial condition. Our future success also depends
on our continuing ability to attract and retain highly qualified technical,
editorial and managerial personnel. Competition for such personnel is intense,
and we have, at times, experienced difficulties in attracting the desired
number of such individuals.

OUR BUSINESS DEPENDS ON THE GROWTH OF THE INTERNET

      Our market is new and rapidly evolving. Our success is highly dependent
upon continued growth in the use of the Internet generally and, in particular,
as a medium for advertising, information services and commerce.

Internet usage may be inhibited for a number of reasons, such as:

      o     the Internet infrastructure may not be able to support the demands
            placed on it, and its performance and reliability may decline as
            usage grows,

      o     security and authentication concerns with respect to the
            transmission over the Internet of confidential information, such as
            credit card numbers, and attempts by unauthorized computer users,
            so-called hackers, to penetrate online security systems,

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

      o     the lack of availability of cost-effective, high-speed services.

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

ADOPTION OF THE INTERNET AS AN ADVERTISING MEDIUM IS UNCERTAIN

      Our business, results of operations and financial condition would be
materially adversely affected if the Internet advertising market develops more
slowly than we expect or if we are unsuccessful in increasing our advertising
revenues. We derive a substantial portion of our revenue from the sale of
advertisements on our Web sites. Since the Internet advertising market is new
and rapidly evolving, we cannot yet gauge its effectiveness as compared to
traditional advertising media.

      The adoption of Internet advertising, particularly by those entities that
have historically relied upon traditional media for advertising, requires the
acceptance of a new way of conducting business, exchanging information and
advertising products and services. Advertisers that have traditionally relied
upon other advertising media may be reluctant to advertise on the Internet.
These businesses may find Internet advertising to be less effective than
traditional advertising media for promoting their products and services. Many
potential advertisers have little or no experience using the Internet for
advertising purposes. Consequently, they may allocate only limited portions of
their advertising budgets to Internet advertising.

       Advertisers may not advertise on our Web sites or may pay less for
advertising on our Web sites if they do not believe that they can reliably
measure the effectiveness of Internet advertising or the demographics of the
user viewing their advertisements. We use both internal measurements and
measurements provided to us by third parties. If these third parties are unable
to continue to provide these services, we would have to perform them ourselves
or obtain them from another provider. This could cause us to incur additional
costs or cause interruptions in our business while we are replacing these
services. In addition, we are implementing additional systems designed to
record demographic data on our users. If we do not implement these systems
successfully, we may not be able to accurately evaluate the demographic
characteristics of our users. Moreover, "filter" software programs that limit
or prevent advertising from being delivered to an Internet user's computer are
available. Widespread adoption of this software could adversely affect the
commercial viability of Internet advertising.

      To the extent that minimum guaranteed impression levels are not met
ratably over the contract period, we defer recognition of the corresponding
pro-rata portion of the revenues related to such unfulfilled obligation until
the guaranteed impression levels are achieved. Advertising based on
impressions, or the number of times an advertisement is delivered to users,
comprises virtually all of our current revenues. To the extent that minimum
impression levels are not achieved for any reason, we may be required to
provide additional impressions after the contract term, which would reduce our
advertising inventory.






                                      10
<PAGE>   12

      Our revenues could be adversely affected if we are unable to adapt to
other Internet advertising pricing models that are adopted as industry
standard. It is difficult to predict which, if any, pricing models for Internet
advertising will emerge as the industry standard. This makes it difficult to
project our future advertising rates and revenues.

WE MAY NOT BE ABLE TO ADAPT AS INTERNET TECHNOLOGIES AND CUSTOMER DEMANDS
CONTINUE TO EVOLVE

      To be successful, we must adapt to rapidly changing Internet technologies
by continually enhancing our Web sites and introducing new services to address
our customers' changing demands. We could incur substantial costs if we need to
modify our services or infrastructure in order to adapt to changes affecting
providers of Internet services. Our business, results of operations and
financial condition could be materially adversely affected if we incurred
significant costs to adapt, or cannot adapt, to these changes.

CONCERNS REGARDING SECURITY OF TRANSACTIONS AND TRANSMITTING CONFIDENTIAL
INFORMATION OVER THE INTERNET

      A significant barrier to electronic commerce and communications is the
secure transmission of confidential information over public networks. We rely
on encryption and authentication technology licensed from third parties to
provide the security and authentication necessary to effect secure transmission
of confidential information. We cannot assure you that advances in computer
capabilities, new discoveries in the field of cryptography or other events or
developments will not result in a compromise or breach of the algorithms we use
to protect customer transaction data. If any such compromise of our security
were to occur it could have a material adverse effect on our business, results
of operations and financial condition. If someone is able to circumvent our
security measures, such person could misappropriate proprietary information or
cause interruptions in our operations. We may be required to expend significant
capital and other resources to protect against the threat of such security
breaches or to alleviate problems caused by such breaches. Concerns over the
security of Internet transactions and the privacy of users may also inhibit the
growth of the Internet generally, and the Web in particular, especially as a
means of conducting commercial transactions. To the extent that our activities
or the activities of third party contractors involve the storage and
transmission of proprietary information, such as credit card numbers, security
breaches could expose us to a risk of loss or litigation and possible
liability. We cannot assure you that our security measures will prevent
security breaches or that failure to prevent such security breaches would not
have a material adverse effect on our business, results of operations and
financial condition.

REGULATORY AND LEGAL UNCERTAINTIES COULD HARM OUR BUSINESS

      Any new law or regulation pertaining to the Internet, or the application
or interpretation of existing laws, could decrease the demand for our service,
increase our cost of doing business or otherwise have a material adverse effect
on our business, results of operations and financial condition. There is, and
will be, an increasing number of laws and regulations pertaining to the
Internet. These laws or regulations may relate to liability for information
retrieved from or transmitted over the Internet, online content regulation,
user privacy, taxation and the quality of products and services. Moreover, the
applicability to the Internet of existing laws governing intellectual property
ownership and infringement, copyright, trademark, trade secret, obscenity,
libel, employment, personal privacy and other issues is uncertain and
developing.

      Our contests and sweepstakes may be subject to state and federal laws
governing lotteries and gambling. We seek to design our contest and sweepstakes
rules to fall within exemptions from such laws and restricts participation to
individuals over 18 years of age who reside in jurisdictions within the United
States and Canada in which the contests and sweepstakes are lawful. We cannot
assure you that our contests and sweepstakes will be exempt from such laws or
that the applicability of such laws to us would not have a material adverse
effect on our business, results of operations and financial condition.






                                      11
<PAGE>   13

WE MAY BE LIABLE FOR THE CONTENT WE MAKE AVAILABLE ON THE INTERNET

      We may be subject to legal claims relating to the content we make
available on our Web sites, or the downloading and distribution of such
content. For example, persons may bring claims against us if material that is
inappropriate for viewing by young children can be accessed from our Web sites.
Claims could also involve such matters as defamation, invasion of privacy and
copyright infringement. Providers of Internet products and services have been
sued in the past, sometimes successfully, based on the content of material.
Although we carry general liability insurance, our insurance may not cover
potential claims of this type or may not be adequate to cover all costs
incurred in defense of potential claims or to indemnify us for all liability
that may be imposed. Any costs or imposition of liability that is not covered
by insurance or in excess of insurance coverage could have a material adverse
effect on our business, results of operations and financial condition.
Implementing measures to reduce our exposure to this liability may require us
to spend substantial resources and limit the attractiveness of our service to
users.

OUR SYSTEMS MAY NOT BE YEAR 2000 COMPLIANT

      We utilize a significant number of computer software programs and
operating systems across our entire organization, including applications used
in operating our various Web sites, member services, e-commerce, and various
administrative and billing functions. To the extent that our software
applications contain source codes that are unable to appropriately interpret
the upcoming calendar year 2000, some level of modification, or even possible
replacement of such applications may be necessary.

      We have retained a consulting firm to help assess our Year 2000
compliance. The assessment is currently being conducted in four phases, the
first two of which have been completed. During Phase One, we analyzed
facilities, applications, network, distributed computing, infrastructure, and
data in order to determine the size, scope, and complexity of our exposure to
Year 2000. During Phase Two, specific strategies required to bring exposure
areas into compliance were formulated. Additionally, during Phase Two, we began
interviewing hardware, software, market feed, and firmware vendors for Year
2000 compliance plans. The results of the first and second phases were used to
develop a compliance/renovation approach, budget, and project plan which
includes an analysis of compliance strategies, cost parameters and timelines.
During Phase Three, which is currently in process, we will complete the
renovations of software and applications, implement hardware patches, develop
project contingencies and complete final testing. Phase Four will complete the
process with the development of a contingency plan for any hardware or software
failure. Phase Four is scheduled to begin in June 1999. We expect to be
substantially Year 2000 compliant by the end of June 1999 with respect to our
mission-critical computing infrastructure, associated applications, and
strategic vendors/suppliers.

      The costs we incurred during 1998 to address the Year 2000 compliance
were approximately $143,750. We estimate we will incur a maximum of $500,000 in
direct costs during 1999 to support our compliance initiatives. Although we
expect to be Year 2000 compliant on or before December 31, 1999, we cannot
assure you that we will not experience serious unanticipated negative
consequences and/or material costs caused by undetected errors or defects in
the technology used in our internal systems or by failures of our vendors and
partners to address their Year 2000 issues in a timely and effective manner.

      Should miscalculations or other operational errors occur as a result of
the Year 2000 issue, we, or the parties on which we depend, may be unable to
produce reliable information or to process routine transactions. Furthermore,
in the worst case, we, or the parties on which we depend, may, for an extended
period of time, be incapable of conducting critical business activities which
include, but are not limited to, the production and delivery of our Internet
sites, invoicing customers and paying vendors, which could have a material
adverse effect on our business, prospects, financial condition and operating
results.

WE MAY NOT BE ABLE TO ACQUIRE OR MAINTAIN EFFECTIVE WEB ADDRESSES

      We hold rights to various Web domain names, including
"cbs.sportsline.com," "golfweb.com" and "vegasinsider.com," among others.
Governmental agencies typically regulate domain names. These regulations are
subject to change. We may not be able to acquire or maintain appropriate domain
names in all countries in which we do business. Furthermore, regulations
governing domain names may not protect our trademarks and similar proprietary
rights. We may be unable to prevent third parties from acquiring domain names
that are similar to, infringe upon or diminish the value of our trademarks and
other proprietary rights.

THE PRICE OF THE NOTES AND OUR COMMON STOCK IS HIGHLY VOLATILE

      The trading price of the notes and our Common Stock fluctuates
significantly. For example, during the 52-week period ended March 31, 1999, the
reported closing price of our common stock on the Nasdaq National Market was as
high as $57.81 and as low as $7.69. Trading prices of the notes and the common
stock may fluctuate in response to a number of events and factors, such as:

      o     quarterly variations in operating results,

      o     announcements of technological innovations,

      o     new services, products and strategic developments by us or our
            competitors,

      o     changes in financial estimates or recommendations by securities
            analysts, and

      o     the operating and stock price performance of other companies.

      In addition, the stock market has experienced volatility that has
particularly affected the market prices of equity securities of companies
within certain industry groups such as technology companies and
Internet-related companies in particular, and that often has been unrelated to
the operating performance of such companies. These broad market fluctuations
may materially adversely affect the trading price of the notes and the common
stock, regardless of our operating performance.

THE NOTES ARE SUBORDINATED TO OUR SENIOR DEBT

      The notes are unsecured and subordinated to our existing and future
senior indebtedness. In the event of our bankruptcy, liquidation or
reorganization or acceleration of the notes due to an event of default, we will
pay our obligations on the notes only after we have paid all of our senior
indebtedness in full. Our assets may not be sufficient to cover amounts due on
any of the notes. The notes also will be effectively subordinated to the
liabilities, including trade payables, of any of our subsidiaries.

      As of March 31, 1999, we had no material indebtedness outstanding that
constituted senior indebtedness. Neither we nor our subsidiaries are prohibited
under the indenture from incurring additional debt. Additional debt could
prevent us from meeting our obligations on the notes. From time to time we and
our subsidiaries likely will incur additional debt, including senior
indebtedness. See "Description of Notes - Subordination of Notes."

REDEMPTION OF THE NOTES IS SUBJECT TO CERTAIN LIMITATIONS

      We may not have sufficient funds to pay the repurchase price in cash on a
repurchase event. In addition, a repurchase event may result in a default under
one or more agreements governing our senior indebtedness, whether the
repurchase price is paid in common stock or cash. In this event, the
subordination provisions may prevent us from making any cash payment on the
notes, including a payment of the repurchase price, unless we first obtained
the consent of the holders of defaulted senior indebtedness or repay the senior
indebtedness in full.

      The repurchase event may have the effect of delaying, deferring or
preventing a change of control or other attempt to acquire control of us. As a
result, the right may render more difficult a merger, consolidation or tender
offer, or an assumption of control by a holder of a large block of our shares
and the removal of incumbent management. The change of control repurchase
feature was a result of negotiations between us and the initial purchasers in
the initial private placement. The repurchase feature is not the result of our
knowledge of any specific effort to accumulate shares of common stock or to
obtain control of us by means of a merger, tender offer, solicitation or
otherwise, or part of a plan by us to adopt a series of anti-takeover
provisions. We have no present intention to engage in a transaction involving a
change of control, although it is possible that we would decide to do so in the
future.

THERE IS CURRENTLY NO PUBLIC MARKET FOR THE NOTES

      The initial purchasers of the notes, though they have advised us that
they intend to make a market in the notes, are not obligated to do so and may
discontinue market making at any time without notice. Their market-making
activity will be subject to the limits imposed by the securities laws. We
cannot guarantee that the market for the notes will be maintained. The trading
price of notes will decline if there ceases to be an active trading market for
them. We do not intend to apply for listing of the notes on any securities
exchange.

      SportsLine USA will not receive any proceeds from the sale of the notes
or the common stock by the selling security holders.

                       RATIO OF EARNINGS TO FIXED CHARGES

      The following table shows the amounts by which our earnings were
insufficient to cover fixed charges on a historical basis for the fiscal years
indicated, except for 1994, our initial year of operations, which began in
February 1994. Earnings consist of income before income taxes plus fixed
charges. Fixed charges consist of interest charges and the portion of rent
expense under operating leases representing interest, which is estimated to be
one-third of rent expense.

                              DESCRIPTION OF NOTES

      The notes were issued under an indenture dated as of March 15, 1999,
between us and State Street Bank and Trust Company, as trustee. Many of the
terms and conditions applicable to the notes are contained in the indenture.
The following summarizes some, but not all, of the provisions of the notes and
the indenture. Prospective buyers of notes should refer to the actual terms of
the notes and the indenture for the definitive terms and conditions. The
indenture and a form of the notes have been filed as exhibits to the
registration statement of which this prospectus is a part. As used in this
Description of notes, the words "we," "us," or "our" do not include any of our
subsidiaries.

GENERAL

      The aggregate principal amount of the notes is limited to $150,000,000.
The notes will be issued in fully registered form and denominated in integral
multiples of $1,000. The notes will mature on April 1, 2006 unless earlier
converted, redeemed or repurchased.

      The notes bear interest at an annual rate of 5%. Interest will be paid on
April 1 and October 1 of each year, commencing October 1, 1999, and upon
maturity, redemption and repurchase. The record dates for payment of interest
on the notes is March 15 and September 15. If any payment date falls on a day
that is not a business day, payment will be made on the next business day and
no additional interest will be paid. Interest will be computed the basis of a
360 day year comprised of twelve 30-day months.

      We will maintain an office in the Borough of Manhattan, State of New York
where notes may be presented for registration, transfer, exchange or
conversion. Initially this will be an office or agency of the trustee. Interest
payable on the notes will generally be paid by check and mailed to the holders
of record as of the close of business on the last Business Day before the
related record date. Holders of more than $2,000,000 of notes may request that
their interest be paid by wire transfer.

      We are not restricted under the indenture from entering into any
transaction or altering the nature of our business, even if the transaction or
alteration would be detrimental to the holders of the notes. For example, we
may incur substantial amounts of debt or sell our assets to an acquiror without
violating the terms of the indenture. If the transaction involves a "change of
control," a holder will have the right to require us to repurchase their notes,
in the manner described in "--Repurchase at Option of Holders Upon a Repurchase
Event." Dividends, stock splits and other distributions may result in an
adjustment to the conversion price of the notes.

      Holders will not be required to pay a service charge for registration or
transfer of their notes. However, we may require you to pay any tax or other
governmental charge in connection with the transfer. We are not required to
exchange or register the transfer of:

      o     any notes selected for redemption for a period of 15 days prior to
            redemption,

      o     any note or portion selected for redemption,

      o     any note or portion surrendered for conversion , or

      o     any note or portion surrendered for repurchase but not withdrawn in
            connection with a repurchase event.

      The notes will have no sinking fund. A sinking fund is a custodial or
similar account into which regularly scheduled deposits are made for purposes
of redeeming or repurchasing of securities.

CONVERSION

      Each holder may convert its notes, in whole or in part, into our common
stock at an initial conversion rate of 15.355 shares of common stock per $1,000
principal amount of notes, which is equivalent to a conversion price of
approximately $65.125 per share. A note may be converted at any time prior to
the close of business on the final maturity date of the notes. If the notes are
called for redemption, the holder's conversion rights on the called notes will
expire at the close of business of the last business day before the redemption
date. Any note that has been presented for repurchase following a repurchase
event may only be converted if the holder delivers a notice of withdrawal prior
to the close of business on the last business day before the repurchase date.





                                      16
<PAGE>   18

      A holder may exercise the right to convert their notes in denominations
of integral multiples of $1,000 by delivering their notes to the office of our
conversion agent accompanied by a conversion notice in the form required by the
indenture. If the date of conversion occurs on or after a record date, but
before the next interest payment date, and we have not called the notes for
redemption, the notes to be converted and conversion notice must be accompanied
by a payment equal to the amount of the interest payable on the next interest
payment date. Instead of issuing a fractional share upon conversion, we will
pay a cash adjustment based on the closing market price of the common stock on
the last business day before the date of conversion.

      A holder that presents a note for conversion will not be required to pay
any taxes or duties resulting from the issuance of our common stock, but a
holder will be required to pay any tax or duty resulting from the issuance of
common stock in the name of any person other than the holder.

      The conversion price shall initially be $1,000 divided by the conversion
rate of 15.355 and shall be adjusted upon certain events including:

      o     our issuing common stock as a dividend or distribution on our
            common stock,

      o     our dividing or combining our outstanding shares of common stock
            into a different number of shares,

      o     subject to certain exceptions, our issuing rights or warrants to
            all holders of our common stock to purchase common stock at less
            than the current market price of the common stock,

      o     our making a dividend or distribution to the holders of our common
            stock of capital stock or debt or assets, excluding:

            o     common stock distributions covered by the first bullet point,

            o     right or warrant distributions covered by the third bullet
                  point, and

            o     cash distributions covered by the next bullet point,

      o     our paying a cash dividend or distribution to all holders of our
            common stock or our repurchasing any shares of our common stock
            (whether by tender offer or otherwise) in a transaction in which
            all holders of our common stock are invited to participate if, when
            aggregated with all other dividends, distributions or repurchases
            during the prior 12 calendar months for which no adjustment to the
            conversion price has been made, the dividend, distribution or
            repurchase exceeds 10% of the Company's market capitalization
            (calculated by multiplying the current market price of its common
            stock by the number of outstanding shares of common stock, on a
            fully diluted basis), and

      o     payment on certain tender offers or exchange offers by a third
            party if, as of the closing date of the offer, our board of
            directors does not recommend rejection of the offer.

      We will only make an adjustment in the last bullet point if the tender
offer increases the person's ownership to more than 25% of our outstanding
common stock. We won't make any adjustment in the last bullet point if the
tender offer is a merger or transaction described below under "--Consolidation,
Merger or Assumption."

      If we implement a stockholders' rights plan that grants rights to the
holders of our common stock, the indenture requires that the plan also allow
the holders of notes to receive the same rights upon conversion of the notes
into common stock, on a share-for-share basis.

      In the event of any reclassification or other change in our common stock,
or our consolidation, merger, or combination with or into another entity or a
sale or conveyance to another person of our property and assets as an entirety
or substantially as an entirety, that results in the holders of our common
stock becoming entitled to receive stock, other securities, cash or other
property or assets on or in exchange for their shares of common stock, the
holders will generally be entitled to convert their notes into the type of
property or assets that they would have received had the notes been converted
immediately before such event. If the holders of common stock have the right to
chose between or among alternative types of property, the holders of notes will
receive the kind and amount of property received per share by a plurality of
non-electing shares. All references in this Description of notes to "common
stock" in the context of any holder's right to convert should be construed to
mean either our common stock or the other property into which the note is
convertible.





                                      17
<PAGE>   19

      The holders of notes or common stock issuable upon conversion of the
notes may, in certain circumstances, be deemed to have received a distribution
or dividend subject to United States income tax as a result of an adjustment
(or the nonoccurrence of an adjustment) to the conversion price. See "Certain
Federal Income Tax Considerations."

      We are permitted to reduce the conversion price of the notes for certain
periods of time, if our Board of Directors deems it advisable. Any such
reduction shall be effective for not less than 20 days. We may also reduce the
conversion price to avoid or diminish income tax to holders of our common stock
in connection with a dividend or distribution of stock or similar event. We are
required to give at least 15 days prior notice of any such reduction.

      No adjustment in the conversion price will be required unless it would
result in a change in the conversion price of at least 1%. Any adjustment not
made will be taken into account in subsequent adjustments.

OPTIONAL REDEMPTION BY US

      On or after April 2, 2002, we may elect to redeem all or part of the
notes. We will provide the holders at least 30 but not more than 60 days'
notice of our intent to redeem.

      If we elect to redeem the notes the redemption price will be as follows,
expressed as a percentage of the principal amount of the notes to be redeemed:

                                                                      Redemption
      Redemption Date                                                    Price
      ---------------                                                 ---------
      From April 2, 2002 through March 31, 2003........................102.857%
      From April 1, 2003 through March 31, 2004........................102.143
      From April 1, 2004 through March 31, 2005........................101.429
      From April 1, 2005 through March 31, 2006........................100.714

      and 100% at April 1, 2006.

      We will also pay accrued interest to, but excluding, the date of
redemption. If a redemption date occurs on an interest payment date, the
interest will be payable to the holder of record as of the record date.

      In the event of a partial redemption, the trustee will select the notes
to be redeemed by lot, or in its discretion, on a pro rata basis or by any
other method that the trustee considers fair and appropriate, as long as the
method chosen is not prohibited by any exchange or automated market. Partial
redemptions of any note must be in integral multiples of $1,000. A new note
will be issued having a principal amount equal to the unredeemed principal
portion of the old note. In the event that a holder partially converts a note
that has been called for a partial redemption, the conversion shall first
reduce the portion of the note called for redemption.

      In addition, we may at any time or from time to time repurchase notes in
the open market or in private transactions. We will cancel any notes that we
repurchase.

REPURCHASE AT OPTION OF HOLDERS UPON A REPURCHASE EVENT

      If a repurchase event occurs, each holder will have the right to require
us to repurchase all or part of its notes on the 40th calendar day after the
date that we mail a notice of repurchase to the holders. The purchase price
will be 100% of the principal amount of the notes. We will also pay accrued
interest to, but excluding, the repurchase date. However, if a repurchase date
occurs on an interest payment date, the interest becoming due on the interest
payment date will be payable to the holder of record on the Record Date, which
will satisfy our obligation to otherwise pay interest in connection with the
repurchase.

      At our option, instead of paying the repurchase price in cash, we may pay
the repurchase price in shares of our common stock, valued at 95% of the
average of the closing prices of our common stock for the five consecutive
trading days prior to such repurchase. We may not make payment in shares of our
common stock unless we satisfy certain conditions with respect to such payment
set forth in the indenture.





                                      18
<PAGE>   20

      We are required to mail a notice to each holder of record within 15
calendar days after the occurrence of a repurchase event. The notice must
describe the repurchase event, the holder's right to elect repurchase of the
notes and the repurchase date. We must deliver a copy of the notice to the
trustee and cause a copy, or a summary of the notice, to be published in a
newspaper of general circulation in the City of New York. A holder may exercise
its repurchase rights by delivering written notice to us and the trustee
indicating that the holder has elected to exercise its repurchase rights. The
notice is to be accompanied by the notes endorsed for transfer to us. The
exercise notice is to be delivered to us on or before the close of business on
the 35th calendar day after the date the repurchase notice is mailed.

      A "change in control" will be deemed to have occurred when:

      o     any person or group is or becomes the beneficial owner of shares
            representing more than 50% of our voting stock,

      o     our stockholders approve any plan or proposal for our liquidation,
            dissolution or winding up,

      o     we

           (A)   consolidate with or merge into any other corporation or any
                 other corporation merges into us and our outstanding common
                 stock is changed or exchanged for other assets or securities
                 unless our stockholders immediately before the transaction own
                 immediately following the transaction at least 51% of the
                 combined voting power of the corporation resulting from the
                 transaction in substantially the same proportion as their
                 ownership of our voting stock immediately before the
                 transaction, or

          (B)    convey, transfer or lease all or substantially all of our 
                 assets to any person, or

      o     any time continuing directors do not constitute a majority of our
            Board of Directors.

      A change in control will not be deemed to have occurred if:

      o     the last sale price of our common stock for any five trading days
            during the ten trading days immediately before any event listed in
            the bullet points above is at least equal to 105% of the conversion
            price in effect on that day, or

      o     in the case of a merger or consolidation, all of the consideration
            in such merger or consolidation constituting the change in control
            consists of common stock traded on a United States national
            securities exchange or quoted on the Nasdaq National Market and as
            a result of the transaction the notes become convertible solely
            into that common stock.

      The term "continuing director" means at any date a member of our Board of
Directors:

      o     who was a member of our Board of Directors on March 19, 1999, or

      o     who was nominated or elected by at least a majority of the
            directors who were continuing directors at the time of the
            nomination or election or whose election to our Board of Directors
            was recommended by at least a majority of the directors who were
            continuing directors at the time of the nomination or election or
            by the nominating committee comprised of our independent directors.

      The term "repurchase event" means a change in control or a termination of
trading.

      A "termination of trading" is considered to have occurred if our common
stock is neither listed for trading on a United States national securities
exchange nor approved for trading on an established automated over-the-counter
trading market in the United States.

      If the phrase "all or substantially all" used in the definition of change
in control were to be interpreted, the interpretation would likely depend on
the facts and circumstances existing at such time. As a result, there may be
uncertainty as to whether or not a sale or transfer of "all or substantially
all" of our assets has occurred.

      We may not have sufficient funds to pay the repurchase price in cash on a
repurchase event. In addition, a repurchase event may result in a default under
one or more agreements governing our senior indebtedness, whether the
repurchase price is paid in common stock or cash. In this event, the
subordination provisions may prevent us from making any cash payment on the
notes, including a payment of the repurchase price, unless we first obtained
the consent of the holders of defaulted senior indebtedness or repay the senior
indebtedness in full.

      The repurchase event may have the effect of delaying, deferring or
preventing a change of control or other attempt to acquire control of us. As a
result, the right may render more difficult a merger, consolidation or tender
offer, or an assumption of control by a holder of a large block of our shares
and the removal of incumbent management. The change of control repurchase
feature was a result of negotiations between us and the initial purchasers in
the initial private placement. The repurchase feature is not the result of our
knowledge of any specific effort to accumulate shares of common stock or to
obtain control of us by means of a merger, tender offer, solicitation or
otherwise, or part of a plan by us to adopt a series of anti-takeover
provisions. We have no present intention to engage in a transaction involving a
change of control, although it is possible that we would decide to do so in the
future.

      Rule 13e-4 under the Exchange Act requires the distribution of certain
information to security holders in the event of certain issuer tender offers
and may apply in the event of a repurchase. We will comply with this rule to
the extent applicable.

SUBORDINATION

      All payments under the notes are subordinate to the prior payment in full
of all existing and future senior indebtedness as provided in the indenture.
Upon any distribution of our assets upon any dissolution, winding up,
liquidation or reorganization of us, payments on the notes will be subordinated
in right of payment to the prior payment in full of all senior indebtedness.
However, if the notes are accelerated following an event of default, the
holders of any senior indebtedness then outstanding will be entitled to payment
in full before the holders of the notes are entitled to receive any payment on
the notes.

      In addition, we may not make any payments on the notes if:

      o     we fail to pay any payment on any designated senior indebtedness
            beyond any grace period, or

      o     any other default occurs and is continuing under any designated
            senior indebtedness that permits holders of the designated senior
            indebtedness to accelerate the maturity of any designated senior
            indebtedness and the holders of designated senior indebtedness send
            the trustee and us a payment blockage notice of the default.

      We may resume making payments on the notes

      o     in the case of a payment default, when the default is cured or
            waived or ceases to exist, and

      o     in the case of a nonpayment default, the earlier of when the
            default is cured or waived or ceases to exist or 179 days after
            receipt of the payment blockage notice.

      No new period of payment blockage may be commenced pursuant to a payment
blockage notice unless:

      o     365 days have elapsed since our receipt of the prior payment
            blockage notice, and

      o     all scheduled payments on the notes have been paid in full, or, if
            not paid in full, neither the trustee nor any of the holders of
            notes has begun proceedings to enforce the right of the holders to
            receive such payments.

      No default that existed on any senior indebtedness on the date of
delivery of any payment blockage notice may be the basis for a subsequent
payment blockage notice.

      The term "senior indebtedness" means the principal, premium, if any, and
interest on, including bankruptcy interest, and any other payment on the
following:

      o     all indebtedness of SportsLine for money borrowed that is evidenced
            by notes, debentures, bonds or other securities,

      o     all indebtedness of SportsLine due and owing with respect to
            letters of credit,






                                      20
<PAGE>   22

      o     all indebtedness or other obligations of SportsLine due and owing
            with respect to interest rate and currency swap agreements, cap,
            floor and collar agreements, currency spot and forward contracts
            and other similar agreements and arrangements,

      o     all indebtedness consisting of commitment or standby fees due and
            payable to lending institutions with respect to credit facilities
            or letters of credit available to SportsLine,

      o     all obligations of SportsLine under leases required or permitted to
            be capitalized under generally accepted accounting principles,

      o     all indebtedness or obligations of the type listed in the bullet
            points above assumed by or guaranteed by SportsLine or in effect
            guaranteed, directly or indirectly, by SportsLine through an
            agreement to purchase, and

      o     any amendments or modifications of indebtedness of type listed in
            the bullet points above.

      Senior indebtedness shall not include:

      o     any debt or amendment or modification that is not senior to or is
            on the same basis as the notes,

      o     any indebtedness to any or our subsidiaries,

      o     indebtedness for trade payables or the deferred purchase price of
            assets or services incurred in the ordinary course of business, or

      o     the notes.

      The term "designated senior indebtedness" means our obligations under any
senior indebtedness that expressly provides that it shall be designated senior
indebtedness.

      If the trustee or any holder of notes receives any payment or
distribution of our assets of any kind on the notes in contravention of any of
the terms of the indenture, then such payment or distribution will be held by
the recipient in trust for the benefit of the holders of senior indebtedness,
and will be immediately paid or delivered to the holders of senior indebtedness
or their representative or representatives.

      We are the sole obligor on the notes. If, in the future, a significant
portion of our consolidated operations is conducted through our subsidiaries,
the cash flow and our ability to service our debt may be dependent upon the
earnings of these subsidiaries and the distribution of those earnings to us.
Each subsidiary will be a separate legal entity, will not be required to
guaranty our obligations with respect to the notes and will have no obligation
to pay any amounts due on the notes or to make any funds available for payment
on the notes. In addition, the payment of dividends and the making of loans and
advances to us by our subsidiaries may be subject to statutory, contractual or
other restrictions. Our right to receive assets of any of our subsidiaries upon
its liquidation or reorganization will be effectively subordinated to the
claims of that subsidiary's creditors, including trade creditors and even if
those claims do not include "senior indebtedness" of that subsidiary, and that
subsidiary's preferred stockholders.

      The indenture will not prevent us from incurring additional indebtedness,
including senior indebtedness. As of March 31, 1999, we had no material
indebtedness outstanding which constituted senior indebtedness.

      The subordination provisions of the indenture and the notes will not
prevent the occurrence of any default or event of default or limit the rights
of any holder of notes to pursue any other rights or remedies with respect to
the notes.

      As a result of the subordination provisions, in the event of the
liquidation, bankruptcy, reorganization, insolvency, receivership or similar
proceedings, holders of the notes may receive less than other creditors on a
ratable basis.

EVENTS OF DEFAULT AND REMEDIES

      The following events constitute "events of default" under the indenture:

      o     our failure to pay the principal of, or premium, if any, on any of
            the notes when due,






                                      21
<PAGE>   23

      o     our failure to pay interest or liquidated damages on the notes when
            due if such failure continues for 30 days,

      o     our failure to deliver shares of our common stock required to be
            delivered upon conversion of a note if the failure continues for 5
            days,

      o     our failure to perform any covenant in the indenture if such
            failure continues for 60 days after notice is given by the trustee
            or by the holders of not less than 25% of the notes,

      o     our failure following a repurchase event to repurchase any notes,

      o     our failure to provide timely notice of a repurchase event,

      o     our failure or the failure of any of our significant subsidiaries
            to make any payments on any Indebtedness following any applicable
            grace periods, in an amount in excess of $15,000,000 and such
            amount has not been paid or discharged within 30 days after notice
            is given in accordance with the indenture,

      o     a default by us or any of our significant subsidiaries on any
            indebtedness that results in the acceleration of indebtedness in an
            amount in excess of $15,000,000 and such indebtedness or such
            acceleration has not been discharged for 30 days after notice is
            given in accordance with the indenture, or

      o     certain events involving bankruptcy, insolvency or reorganization
            of us or any of our significant subsidiaries.

      The trustee is generally required, within 90 days after its becoming
aware of a default, to provide the registered holders of the notes written
notice of the default. Except in the case of a payment default, the trustee
will not be required to deliver a default notice if it determines in good faith
that withholding the notice is in the best interest of the holders of the
notes.

      If an event of default has occurred and is continuing, the trustee, or
the holders of not less than 25% of the notes, may declare all amounts
outstanding on the notes to be immediately due and payable. If an event of
default occurs resulting from the bankruptcy, insolvency or reorganization of
us, all unpaid principal of and accrued interest on the outstanding notes would
become due and payable immediately without any declaration or other act on the
part of the trustee or holders of notes.

      Holders of a majority of the notes may direct the time, method and place
of conducting any proceeding for any remedy available to the trustee or
exercising any trust or power conferred on the trustee, subject to certain
limitations. Before proceeding to exercise any right or power under the
indenture at the direction of the holders, the trustee will be entitled to
receive from such holders reasonable security or indemnity against any costs,
expenses and liabilities that it might incur as a result. Following an event of
default for nonpayment, each holder to which such default pertains will have
the absolute right to institute suit to enforce payment of any notes held by
it.

      Generally, the holders of not less than a majority of the notes may waive
any default or event of default. However, the consent of all holders will be
required to waive any default and events of default relating to:

      o     a failure by us to make payment on any note,

      o     a failure by us to convert any note into common stock, or

      o     a failure by us to comply with any of the provisions of the
            indenture that would require the consent of affected holders to
            modify.

      We are required, within 120 days of the end of each fiscal year, to send
the trustee a statement of certain of our officers:

      o     stating whether or not to the best of their knowledge we are out of
            compliance with any terms of the indenture or the notes, and

      o     specifying, if any of them has any such knowledge that we are out
            of compliance, the nature of the default.

      We are also required to deliver to the trustee a statement specifying the
nature of any default of which we are aware and any action we have taken to
cure the default.






                                      22
<PAGE>   24

CONSOLIDATION, MERGER OR ASSUMPTION

      We may not consolidate or merge into another person or sell, lease,
convey or transfer all or substantially all of our assets to another person
unless:

      o     either

            (A)   in the case of a merger or consolidation that does not
                  involve a transfer of all or substantially all of our assets,
                  we are the surviving entity, or

            (B)   the resulting corporation is a U.S. corporation and expressly
                  assumes all of our obligations under the notes and the
                  indenture,

      o     no default or event of default exists or would occur, and

      o     certain other conditions are satisfied.

MODIFICATIONS OF THE INDENTURE

      With the consent of the holders of not less than a majority of the notes,
we and the trustee may modify the indenture, any supplemental indenture or the
notes. However, the following modifications require the consent of each holder:

      o     an extension of the maturity of any note,

      o     a reduction in the rate or an extension of the time or payment of
            interest on any note,

      o     a reduction in the principal amount of any note,

      o     a reduction in any amount payable upon redemption or repurchase of
            any note,

      o     any change in our obligation to repurchase any note upon a
            repurchase event if adverse to any holder,

      o     any change that adversely affects the right of any holder to
            institute suit for the payment of any note,

      o     any change in currency in which any note is payable,

      o     any adverse modification to the right to convert the notes,

      o     any adverse modification of the subordination provisions of the
            notes, or

      o     any change to the percentage required to consent to modifications
            and amendments.

SATISFACTION AND DISCHARGE

      We may discharge our obligations under the indenture while notes remain
outstanding if:

      o     all notes are within one year of their scheduled maturity or the
            date on which they are scheduled for redemption, and

      o     we have deposited with the trustee an amount sufficient to pay all
            outstanding notes on their scheduled maturity or redemption date.

REGISTRATION RIGHTS OF THE HOLDERS OF THE NOTES

      Under a registration rights agreement, we are generally required to keep
the shelf registration statement of which this prospectus is a part effective
until the earlier of (1) the sale of all the securities registered under this
prospectus and (2) the expiration of the holding period for the securities held
by people or entities that are not our affiliates under Rule 144(k) under the
Securities Act. We may suspend the use of this prospectus under certain
circumstances relating to pending corporate developments, public filings with
the Securities and Exchange Commission and similar events for a period not to
exceed an aggregate of 90 days in any period of 365 consecutive days. We must
pay predetermined liquidated damages (i) for the notes, at a rate per annum
equal to 0.5% of the principal amount of the notes, and (ii) for any shares of
common stock issued on conversion of the notes, at a rate per annum equal to
0.5% of the conversion price, if the prospectus is unavailable for periods in
excess of those permitted above.






                                      23
<PAGE>   25

      A holder who sells notes or common stock issued upon conversion of the
notes pursuant to this prospectus generally must be named as a selling holder,
deliver this prospectus to purchasers and be bound by certain provisions of the
registration rights agreement. We will pay all expenses of the shelf
registration statement, provide to each registered holder copies of such
prospectus and take certain other actions as are required to permit
unrestricted resales of the notes and the common stock.

      A copy of the registration rights agreement has been filed as an exhibit
to the registration statement of which this prospectus is a part.

GOVERNING LAW

      The indenture and the notes will be governed by the laws of the State of
New York without regard to conflicts of laws principles.

CONCERNING THE TRUSTEE

      State Street Bank and Trust Company, the trustee under the indenture, has
been appointed by us as the initial paying agent, conversion agent, registrar
and custodian with regard to the notes. An affiliate of the trustee is the
transfer agent for our common stock. We may maintain deposit accounts and
conduct other banking transactions with the trustee or its affiliates in the
ordinary course of business, and the trustee and its affiliates may from time
to time in the future provide banking and other services to us in the ordinary
course of their business.

      If the trustee becomes a creditor of us, the indenture and the Trust
Indenture Act of 1939, as amended, may limit the right of the trustee to obtain
payment on or realize on security for its claims. If the trustee develops any
conflicting interest with the holders of notes or us, it must eliminate the
conflict or resign.

                          DESCRIPTION OF CAPITAL STOCK

      Our authorized capital stock consists of 50,000,000 shares of common
stock, $.01 par value per share, and 1,000,000 shares of preferred stock, $0.01
par value per share. The following statements are brief summaries of certain
provisions relating to our capital stock contained in our Certificate of
Incorporation and Bylaws and in the laws of Delaware.

COMMON STOCK

      As of March 31, 1999, there were 22,384,266 shares of our common stock
outstanding. Holders of our 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 such 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 outstanding preferred stock. Upon our liquidation,
dissolution or winding up, holders of our common stock are entitled to receive
ratably our net assets available after the payment of all debts and other
liabilities and subject to the prior rights of any outstanding preferred stock.
Holders of our common stock have no preemptive, subscription, redemption or
conversion rights. The outstanding shares of common stock are 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.

PREFERRED STOCK

      As of March 31, 1999, we had no shares of preferred stock outstanding.
Our Board of Directors is authorized, without further shareholder approval, to
issue from time to time up to an aggregate of 1,000,000 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 such 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 designations of such series. We have no
present plans to issue any shares of preferred stock.






                                      24
<PAGE>   26

REGISTRATION RIGHTS

      Certain of our security holders are entitled to require us to register
under the Securities Act, up to a total of approximately 10.1 million shares of
our common stock (including 1.4 million shares of our common stock which is
issuable upon the exercise of warrants). In the event we propose to register
any of our securities under the Securities Act at any time, these security
holders, subject to certain exceptions, have the right to include their shares
in the registration. In addition, some of these security holders also have the
right, subject to certain conditions and limitations, to require us to prepare
and file a registration statement under the Securities Act with respect to
their shares. We are generally required to bear the expenses of all these
registrations, except underwriting discounts and commissions.

ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF DELAWARE LAW AND THE COMPANY'S
CERTIFICATE OF INCORPORATION AND BYLAWS

      We are subject to the provisions of Section 203 of the Delaware General
Corporation Law regulating corporate takeovers. Section 203 prevents certain
Delaware corporations, including those whose securities are listed on the
Nasdaq National Market, from engaging, under certain circumstances, in a
"business combination" (which includes a merger or sale of more than 10% of the
corporation's assets) with any "interested stockholder" (a stockholder who
acquired 15% or more the corporation's outstanding voting stock without the
prior approval of the corporation's board of directors) for three years
following the date that such stockholder became an "interested stockholder." A
Delaware corporation may "opt out" of Section 203 with an express provision in
its original certificate of incorporation or an express provision in its
certificate of incorporation or bylaws resulting from a stockholders' amendment
approved by at least a majority of the outstanding voting shares. We have not
"opted out" of the provisions of Section 203.

      In addition, certain provisions of our Certificate of Incorporation and
Bylaws may be deemed to have an anti-takeover effect and may delay, defer or
prevent a tender offer or takeover attempt that a shareholder might consider in
its best interest, including those attempts that might result in a premium over
the market price for the shares held by shareholders.

           CLASSIFIED BOARD OF DIRECTORS. Our Board of Directors is divided
      into three classes of directors serving staggered three-year terms. As a
      result, approximately one-third of our directors will be elected each
      year. These provisions, when coupled with the provision of our
      Certificate of Incorporation authorizing only the Board of Directors to
      fill vacant directorships or increase the size of the Board of Directors,
      may deter a shareholder from removing incumbent directors and
      simultaneously gaining control of the Board of Directors by filling the
      vacancies created by such removal with its own nominees.

           SHAREHOLDER ACTION; SPECIAL MEETING OF SHAREHOLDERS. Our Certificate
      of Incorporation provides that shareholders may not take action by
      written consent, but only at duly called annual or special meetings of
      shareholders. Our Certificate of Incorporation further provides that
      special meetings of our shareholders may be called only by the Chairman
      of the Board of Directors or a majority of the Board of Directors.

           ADVANCE NOTICE REQUIREMENTS FOR SHAREHOLDER PROPOSALS AND DIRECTOR
      NOMINATIONS. Our Bylaws provide that shareholders seeking to bring
      business before an annual meeting of shareholders, or to nominate
      candidates for election as directors at an annual meeting of
      shareholders, must provide timely notice in writing. To be timely, a
      shareholder's notice must be delivered to or mailed and received at our
      principal executive offices, not less than 120 days nor more than 150
      days prior to the first anniversary of the date of our notice of annual
      meeting provided with respect to the previous year's annual meeting. For
      example, the date of the notice for our 1999 Annual Meeting is May 14,
      1999. Accordingly, a shareholder's notice to bring business before our
      2000 Annual Meeting must be received by us by January 17, 2000. Our
      Bylaws also specify certain requirements for a shareholder's notice to be
      in proper written form. These provisions may preclude shareholders from
      bringing matters before the shareholders at an annual meeting or from
      making nominations for directors at an annual meeting.







                                      25
<PAGE>   27

           AUTHORIZED BUT UNISSUED SHARES. The authorized but unissued shares
      of our common stock and preferred stock are available for future issuance
      without shareholder approval. 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 and unreserved common
      stock and preferred stock may enable the Board of Directors to issue
      shares to persons friendly to current management which could render more
      difficult or discourage an attempt to obtain control by means of a proxy
      contest, tender offer, merger or otherwise, and thereby protect the
      continuity of our management.

      Delaware 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. Our Certificate of Incorporation requires the affirmative vote of
the holders of at least 80% of the combined voting power of the outstanding
shares of our capital stock entitled to vote for the election of directors to
amend or repeal any of the provisions of our Certificate of Incorporation
listed above. This 80% shareholder vote is also required to amend or repeal any
of the provisions of our Bylaws listed above, although these Bylaws provisions
may also be amended or repealed by a majority vote of the entire Board of
Directors. This 80% shareholder vote would be in addition to any separate class
vote that might in the future be required pursuant to the terms of any
preferred stock that might be outstanding at the time any such amendments are
submitted to stockholders.

LIMITATION OF LIABILITY AND INDEMNIFICATION

      Delaware law authorizes a Delaware corporation to eliminate or limit the
personal liability of a director to the corporation and its stockholders for
monetary damages for breach of certain fiduciary duties as a director. We
believe that such a provision is beneficial in attracting and retaining
qualified directors, and accordingly our Certificate includes a provision
eliminating liability for monetary damages for any breach of fiduciary duty as
a director, except as provided under Delaware law. Pursuant to Delaware law,
our directors are not insulated from liability for breach of their duty of
loyalty (requiring that, in making a business decision, directors act in good
faith and in the honest belief that the action was taken in the best interest
of the corporation), or for certain other claims. The foregoing provisions of
our Certificate may reduce the likelihood of success of derivative litigation
against directors for breaches of their fiduciary duties, even though such an
action, if successful, might otherwise have benefited us and our stockholders.

TRANSFER AGENT AND REGISTRAR

      The transfer agent and registrar for our common stock is EquiServe,
Canton, Massachusetts.

                 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

      This section summarizes the material United States federal income tax
consequences of purchasing, owning, and disposing of the notes and the common
stock into which you may convert the notes. This summary is not a complete
analysis of all the potential tax consequences that you may need to consider
before investing based on your particular circumstances.

      This summary is based on the Internal Revenue Code of 1986, as amended,
the applicable Treasury regulations promulgated or proposed under the Internal
Revenue Code, judicial authority and administrative rulings and practice. Any
of these may change, possibly on a retroactive basis.

      This summary deals only with beneficial owners of notes and common stock
who hold the notes and common stock as "capital assets." It does not address
tax consequences under any special tax rules. Special rules may apply, for
example, to banks, tax-exempt organizations, pension funds, insurance
companies, dealers in securities or foreign currencies, persons participating
in a hedging transaction or a "straddle" or "conversion transaction," or
persons that have a "functional currency" other than the U.S. dollar. In
addition, this discussion does not address the tax consequences to non-U.S.
holders. We have not sought any ruling from the Internal Revenue Service with
respect to the statements and conclusions in this summary. We cannot guarantee
that the IRS will agree with these statements and conclusions.

      Before you invest in the notes, you should consult your own tax adviser
to determine how the United States federal income and estate tax laws apply to
your particular situation and for information about any tax consequences
arising under the laws of any state, local or foreign taxing jurisdiction or
under any applicable tax treaty.

PAYMENT OF INTEREST

      You generally must include interest on a note in your income as ordinary
income at the time you receive or accrue the interest based on your method of
accounting for United States federal income tax purposes. We must pay liquidated
damages to holders of the notes in certain circumstances. According to Treasury
regulations, the possibility of liquidated damages being paid on the notes will
not affect the amount of interest income you recognize, in advance of the
payment of any liquidated damages, if there is only a remote chance as of the
date the notes were issued that you will receive liquidated damages. We believe
that the likelihood that we will pay liquidated damages is remote. Therefore, we
do not intend to treat the potential payment of liquidated damages as part of
the yield to maturity of any note. However, if we pay liquidated damages, you
would treat the payments as interest income when you receive them. Similarly, we
intend to take the position that the likelihood of a repurchase of the notes
upon a repurchase event is remote, and likewise do not intend to treat the
possibility of any premium payable on a repurchase as affecting the yield to
maturity of any note.

MARKET DISCOUNT

      If you purchase a note for an amount that is less than the principal
amount of the note, the difference will be "market discount" for United States
federal income tax purposes, unless the difference is less than one-fourth
(1/4) of one percent of the principal amount of the note multiplied by the
number of complete years to maturity (after you acquire the note). Under the
rules on market discount, you will be required to treat any partial principal
payment on a note, or any gain on a sale, exchange or redemption of a note, as
ordinary income up to the amount of the market discount that has accrued as of
the time of the payment or disposition, to the extent you have not previously
included such market discount in ordinary income. In addition, you may be
required to defer, until the earlier of the maturity date of the note or the
date you dispose of the note in a taxable transaction, the deduction of part or
all of the interest expense on any debt you may incur to purchase the note or
any debt you keep outstanding to carry the note.

      Any market discount on a note will accrue during the period starting on
the date you acquire the note and ending on the maturity date of the note. The
market discount will accrue ratably unless you make an election to accrue the
market discount on the note on a constant interest method. You also may elect to
include market discount in income for United States federal income tax purposes
as it accrues (on either the ratable or constant interest method). If you make
that election, the rule described above requiring the deferral of deductions for
interest expense will not apply. If you make an election to include market
discount in income currently, that election will apply to all market discount
obligations that you acquire on or after the first day of the first taxable year
to which your election applies, and the election may not be revoked without the
consent of the IRS.

AMORTIZABLE BOND PREMIUM

      If you purchase a note for an amount that is more than the principal
amount of the note, the excess will be "amortizable bond premium". You may
elect to amortize the premium over the remaining term of the note on a constant
yield method. However, if you purchase the note at a time when we may redeem the
note at our option for an amount greater than the note's principal amount, the
amount of amortizable bond premium will be determined based on the earlier call
date and the call price payable on that earlier call date, if the result of that
calculation would be a smaller amortizable bond premium. If an earlier call date
is used in calculating the amount of amortizable bond premium and the note is
not called on that date, the note will be treated as maturing on that call date
and then reissued on that date for an amount equal to the call price on that
date, with the amortizable bond premium being recalculated under these rules on
that date. Amortizable bond premium, as it accrues, will reduce the amount of
interest payments on the note on which you are taxable and will reduce your
adjusted tax basis in the note.

      Once you make an election to amortize bond premium on any debt
obligation, including the notes, that election will apply to all debt
obligations that you own on the first day of the taxable year to which the
election relates and to all debt obligations that you acquire after that day.
You make revoke the election only with the consent of the IRS. If you do not
elect to amortize bond premium, the amount of the premium will decrease the
amount of any gain or increase the amount of any loss you recognize on a
disposition of the note.

SALE, EXCHANGE OR REDEMPTION OF THE NOTES

      You generally will recognize gain or loss on the sale, exchange (other
than a conversion) or redemption of a note equal to the difference between (1)
the amount of cash proceeds and the fair market value of any property you
receive on the sale, exchange or redemption (except any portion that is accrued
interest income, which is taxable as ordinary income) and (2) your adjusted tax
basis in the note. Your adjusted tax basis generally will equal the cost of the
note to you, reduced by any principal payments you have received and any
amortizable bond premium you have taken into account and increased by any
market discount you have included in income. That gain or loss generally will
be capital gain or loss, except to the extent of any accrued market discount
(see "--Market Discount" above). Capital gain or loss will be long-term if you
have held the note for more than one year and will be short-term if you have
held the note for one year or less. Long-term capital gains for noncorporate
taxpayers, including individuals, are taxed at a maximum rate of 20%, and
short-term capital gains at a maximum rate of 39.6%. Corporate taxpayers pay a
maximum regular tax rate of 35% on all net capital gains and ordinary income.

CONVERSION OF THE NOTES

      You generally will not recognize any income, gain or loss on conversion
of a note into common stock, except for any cash you receive instead of a
fractional share of common stock. Your tax basis in the common stock will be
the same as your adjusted tax basis in the note at the time of conversion. For
capital gains purposes, your holding period for the common stock will generally
include the holding period of the note you converted.

      You should treat cash you receive instead of a fractional share of common
stock as a payment in exchange for the fractional share of common stock. This
will result in capital gain or loss (measured by the difference between the
cash you receive for the fractional share and your adjusted tax basis in the
fractional share).

DIVIDENDS ON COMMON STOCK

      Generally a distribution on common stock (probably including any 
liquidated damages) is treated as a dividend and taxed as ordinary income to the
extent of our current and/or accumulated earnings and profits. A distribution in
excess of earnings and profits is treated as a tax-free return of capital to the
extent of your tax basis in the common stock, on a share-by-share basis, and
then as gain from the sale or exchange of such stock.

      A dividend to a corporate holder may qualify for a deduction of 70% of the
dividend received, subject to limitations in certain cases, if the holder owns
less than 20% of the voting power and value of our stock (disregarding certain
nonvoting, nonconvertible, nonparticipating preferred stock). A corporate holder
that owns 20% or more of the voting power or value of our stock (similarly
disregarding such preferred stock) generally will qualify for an 80% dividends
received deduction.

ADJUSTMENTS TO CONVERSION PRICE

      The conversion price of the notes may change under certain circumstances.
In such a case, you may be treated as having received a constructive
distribution whether or not you ever exercise your conversion privilege. The
constructive distribution will be taxed as ordinary income, subject to a
possible dividends received deduction if you are a corporate holder, to the
extent of our current and/or accumulated earnings and profits, if, and to the
extent that, the adjustment in the conversion price increases your proportionate
interest in our assets or earnings and profits. Moreover, common stockholders
will generally be treated as having received a constructive distribution if
there is not a full adjustment to the conversion price of our notes to reflect a
stock dividend or other event increasing the proportionate interest of the
common stockholders in our assets or earnings and profits. In such an event, the
constructive distribution will be taxable as ordinary income (subject to a
possible dividends received deduction if you are a corporate holder) to the
extent of our current and/or accumulated earnings and profits. At this time, we
have a deficit in accumulated earnings and profits and have no current earnings
and profits.

SALE OF COMMON STOCK

      On the sale or exchange of common stock, you generally will recognize
capital gain or loss equal to the difference between (1) the amount of cash and
the fair market value of any property you receive on the sale or exchange and
(2) your adjusted tax basis in the common stock. This capital gain or loss will
be long-term if you have held the stock for more than one year and will be
short-term if you have held the stock for one year or less. Long-term capital
gains for noncorporate taxpayers, including individuals, are taxed at a maximum
rate of 20%, and short-term capital gains at a maximum rate of 39.6%. A
holder's basis and holding period in common stock received upon conversion of a
note are determined as discussed above under "Conversion of the Notes."
Corporate taxpayers pay a maximum regular tax rate of 35% on all net capital
gains and ordinary income.

INFORMATION REPORTING AND BACKUP WITHHOLDING TAX

      In general, a broker or we must report to the Internal Revenue Service
payments of principal, premium and interest on a note, payments of dividends on
common stock, payments of the proceeds of the sale or exchange of a note and
payments of the proceeds of the sale or exchange of common stock. The payer or
broker must backup withhold at the rate of 31% if

      o     the payee fails to furnish a taxpayer identification number to the
            payer or broker or establish an exemption from backup withholding,

      o     the IRS notifies the payer or broker that the number furnished by
            the payee is incorrect,

      o     the payee has underreported interest, dividends or original issue
            discount, or

      o     the payee has failed to certify under penalties of perjury that he
            or she is not subject to backup withholding under the Code.

      Certain holders, including all corporations, are exempt from backup
withholding. You may credit any amounts withheld under the backup withholding
rules against your United States federal income tax or receive a refund, if you
furnish the required information to the IRS.

      Treasury regulations that apply to payments made after December 31, 2000
will modify current information reporting and backup withholding procedures and
requirements. These regulations provide certain presumptions regarding the
status of holders when payments to the holders cannot be reliably associated
with appropriate documentation provided to the payer. For payments made after
December 31, 2000, holders must provide certification, if applicable, that
conforms to the requirements of the regulations, subject to certain
transitional rules permitting certification in accordance with current Treasury
regulations until December 31, 2000. Because the application of these
regulations may depend on your particular circumstances, we urge you to consult
your tax adviser regarding the application of these regulations.

(1)  Assumes conversion of all of the holder's notes at the initial conversion
     rate of 15.355 shares of common stock per $1,000 principal amount of
     notes. This initial conversion price may be adjusted under certain
     circumstances. As a result, the number of shares issuable upon conversion
     of the notes may increase or decrease.

(2)  Calculated pursuant to Rule 13d-3(d)(i) of the Exchange Act based on
     22,384,266 shares of common stock outstanding as of March 31, 1999. In
     calculating the percentage for each holder, we treated as outstanding the
     number of shares of common stock issuable upon conversion of all of the
     applicable holder's notes. However, we did not assume the conversion of any
     other holder's notes.

(3)  Information about other selling security holders will be set forth in
     prospectus supplements, if required.

      We prepared this table based on the information supplied to us by the
selling security holders named in the table.

      The selling security holders listed in the above table may have sold or
transferred, in transactions exempt from the registration requirements of the
Securities Act, some or all of their notes since the date on which the
information is presented in the above table. Information about the selling
security holders may change over time. Any changed information will be set
forth in prospectus supplements.

      Because the selling security holders may offer all or some of their notes
or the underlying common stock from time to time, we can not estimate the
amount of notes or the underlying common stock that will be held by the selling
security holders upon the termination of any particular offering. Please see
"Plan of Distribution" for additional information.

                              PLAN OF DISTRIBUTION

      We will not receive any of the proceeds of the sale of the notes and the
underlying common stock offered by this prospectus. The notes and the
underlying common stock may be sold from time to time to purchasers:

      o     directly by the selling security holders, or

      o     through underwriters, broker-dealers or agents who may receive
            compensation in the form of discounts, concessions or commissions
            from the selling security holders or the purchasers of the notes
            and the underlying common stock.

      The selling security holders and any such broker-dealers or agents who
participate in the distribution of the notes and the underlying common stock
may be deemed to be "underwriters." As a result, any profits on the sale of the
notes and the underlying common stock by selling security holders and any
discounts, commissions or concessions received by any such broker-dealers or
agents might be deemed to be underwriting discounts and commissions under the
Securities Act. If the selling security holders were deemed to be underwriters,
the selling security holders may be subject to certain statutory liabilities
of, including, but not limited to, Sections 11, 12 and 17 of the Securities Act
and Rule 10b-5 under the Exchange Act.

      If the notes and the underlying common stock are sold through
underwriters or broker-dealers, the selling security holders will be
responsible for underwriting discounts or commissions or agent's commissions.

      The notes and the underlying common stock may be sold in one or more
transactions at:

      o     fixed prices,

      o     prevailing market prices at the time of sale,

      o     varying prices determined at the time of sale, or

      o     negotiated prices.

      These sales may be effected in transactions:

      o     on any national securities exchange or quotation service on which
            the notes and underlying common stock may be listed or quoted at
            the time of the sale, including the Nasdaq National Market in the
            case of our common stock,

      o     in the over-the-counter market,

      o     in transactions otherwise than on such exchanges or services or in
            the over-the-counter market, or

      o     through the writing of options.

      These transactions may include block transactions or crosses. Crosses are
transactions in which the same broker acts as an agent on both sides of the
trade.

      In connection with sales of the notes and the underlying common stock or
otherwise, the selling security holders may enter into hedging transactions
with broker-dealers. These broker-dealers may in turn engage in short sales of
the notes and the underlying common stock in the course of hedging their
positions. The selling security holders may also sell the notes and underlying
common stock short and deliver notes and the underlying common stock to close
out short positions, or loan or pledge notes and the underlying common stock to
broker-dealers that in turn may sell the notes and the underlying common stock.

      Our common stock trades on the Nasdaq National Market under the symbol
"SPLN". We do not intend to apply for listing of the notes on any securities
exchange or for quotation through Nasdaq. Accordingly, no assurance can be
given as to the development of liquidity or any trading market for the notes.

      There can be no assurance that any selling security holder will sell any
or all of the notes or the underlying common stock pursuant to this prospectus.
In addition, any notes or underlying common stock covered by this prospectus
that qualify for sale pursuant to Rule 144 or Rule 144A of the Securities Act
may be sold under Rule 144 or Rule 144A rather than pursuant to this
prospectus.

      The selling security holders and any other person participating in such
distribution will be subject to the Exchange Act. The Exchange Act rules
include, without limitation, Regulation M, which may limit the timing of
purchases and sales of any of the notes and the underlying common stock by the
selling security holders and any other such person. In addition, Regulation M
of the Exchange Act may restrict the ability of any person engaged in the
distribution of the notes and the underlying common stock to engage in
market-making activities with respect to the particular notes and the
underlying common stock being distributed for a period of up to five business
days prior to the commencement of such distribution. This may affect the
marketability of the notes and the underlying common stock and the ability of
any person or entity to engage in market-making activities with respect to the
notes and the underlying common stock.

      Pursuant to the registration rights agreement that has been filed as an
exhibit to the registration statement of which this prospectus is a part, we
and the selling security holders will be indemnified by the other against
certain liabilities, including certain liabilities under the Securities Act, or
will be entitled to contribution in connection with these liabilities.

      We have agreed to pay substantially all of the expenses incidental to the
registration, offering and sale of the notes and underlying common stock to the
public other than commissions, fees and discounts of underwriters, brokers,
dealers and agents.

                                 LEGAL MATTERS

      Greenberg Traurig, P.A., Miami, Florida will provide us with an opinion

result in claims for indemnification by any officer or director.

ITEM 17. UNDERTAKINGS

      (a)  The undersigned registrant hereby undertakes:

           (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

                   (i) To include any prospectus required by section 10(a)(3)
                   of the Securities Act of 1933;

                   (ii) To reflect in the prospectus any facts or events arising
                   after the effective date of the registration statement (or
                   the most recent post-effective amendment thereof) which,
                   individually or in the aggregate, represent a fundamental
                   change in the information set forth in the registration
                   statement. Notwithstanding the foregoing, any increase or
                   decrease in volume of securities offered (if the total
                   dollar value of securities offered would not exceed that
                   which was registered) and any deviation from the low or high
                   end of the estimated maximum offering range may be reflected
                   in the form of prospectus filed with the Commission pursuant
                   to Rule 424(b) if, in the aggregate, the changes in volume
                   and price represent no more than a 20% change in the maximum
                   aggregate offering price set forth in the "Calculation of
                   Registration Fee" table in the effective registration
                   statement.

                   (iii) To include any material information with respect to
                   the plan of distribution not previously disclosed in the
                   registration statement or any material change to such
                   information in the registration statement.

           (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment 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.

           (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

      (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Company's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the securities offered thereby, and the offering of such securities
at the time shall be deemed to be the initial bona fide offering thereof.

      (c) Insofar as indemnification for liabilities arising under the
Securities Act 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 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







                                      II-3
<PAGE>   41

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 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.

                                   SIGNATURES

      Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-3 and has duly caused this
Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Fort Lauderdale, State of Florida, on May 20,
1999.

two days prior to the applicable record date. The term "record date" with
respect to any interest payment date shall mean the March 15 or September 15
preceding said April 1 or October 1, respectively.

         Interest on the Notes shall be computed on the basis of a 360-day year
comprised of twelve 30-day months.

         Any interest on any Note which is payable, but is not punctually paid
or duly provided for, on any said April 1 or October 1 (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Noteholder on
the relevant record date by virtue of his having been such Noteholder; and such
Defaulted Interest shall be paid by the Company, at its election in each case,
as provided in clause (1) or (2) below:

                  (1)    The Company may elect to make payment of any Defaulted
         Interest to the persons in whose names the Notes (or their respective
         Predecessor Notes) are registered at the close of business on a
         special record date for the payment of such Defaulted Interest, which
         shall be fixed in the following manner. The Company shall notify the
         Trustee in writing of the amount of Defaulted Interest to be paid on
         each Note and the date of the payment (which shall be not less than
         twenty-five (25) days after the receipt by the Trustee of such notice,
         unless the Trustee shall consent to an earlier date), and at the same
         time the Company shall deposit with the Trustee an amount of money
         equal to the aggregate amount to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the Trustee for
         such deposit prior to the date of the proposed payment, such money
         when deposited to be held in trust for the benefit of the persons
         entitled to such Defaulted Interest as in this clause provided.
         Thereupon the Trustee shall fix a special record date for the payment
         of such Defaulted Interest which shall be not more than fifteen (15)
         days and not less than ten (10) days prior to the date of the proposed
         payment and not less than ten (10) days after the receipt by the
         Trustee of the notice of the proposed payment. The Trustee shall
         promptly notify the Company of such special record date and, in the
         name and at the expense of the Company, shall cause notice of the
         proposed payment of such Defaulted Interest and the special record
         date therefor to be mailed, first-class postage prepaid, to each
         Noteholder as of such special record date at his address as it appears
         in the Note register, not less than ten (10) days prior to such
         special record date. Notice of the proposed payment of such Defaulted
         Interest and the special record date therefor having been so mailed,
         such Defaulted Interest shall be paid to the persons in whose names
         the Notes (or their respective Predecessor Notes) were registered at
         the close of business on such special record date and shall no longer
         be payable pursuant to the following clause (2).

                  (2)    The Company may make payment of any Defaulted Interest
         in any other lawful manner not inconsistent with the requirements of
         any securities exchange or automated quotation system on which the
         Notes may be listed or designated for issuance, and upon such notice
         as may be required by such exchange or automated quotation system, if,
         after notice given by the Company to the Trustee of the proposed
         payment pursuant to this clause, such manner of payment shall be
         deemed practicable by the Trustee.

         Section 2.4     Execution of Notes. The Notes shall be signed in the
name and on behalf of the Company by the facsimile signature of its President,
its Chief Executive Officer, any of its



                                     -11-
<PAGE>   16

Executive or Senior Vice Presidents, or any of its Vice Presidents (whether or
not designated by a number or numbers or word or words added before or after
the title "Vice President") and attested by the facsimile signature of any Vice
President, Secretary or any of its Assistant Secretaries (which may be printed,
engraved or otherwise reproduced thereon, by facsimile or otherwise). Only such
Notes as shall bear thereon a certificate of authentication substantially in
the form set forth on the form of Note attached as Exhibit A hereto, manually
executed by the Trustee (or an authenticating agent appointed by the Trustee as
provided by Section 17.11), shall be entitled to the benefits of this Indenture
or be valid or obligatory for any purpose. Such certificate by the Trustee (or
such an authenticating agent) upon any Note executed by the Company shall be
conclusive evidence that the Note so authenticated has been duly authenticated
and delivered hereunder and that the holder is entitled to the benefits of this
Indenture.

         In case any officer of the Company who shall have signed any of the
Notes shall cease to be such officer before the Notes so signed shall have been
authenticated and delivered by the Trustee, or disposed of by the Company, such
Notes nevertheless may be authenticated and delivered or disposed of as though
the person who signed such Notes had not ceased to be such officer of the
Company; and any Note may be signed on behalf of the Company by such persons
as, at the actual date of the execution of such Note, shall be the proper
officers of the Company, although at the date of the execution of this
Indenture any such person was not such an officer.

         Section 2.5     Exchange and Registration of Transfer of Notes; 
                         Restrictions on Transfer; Depositary.

                  (a)    The Company shall cause to be kept at the Corporate
         Trust Office a register (the register maintained in such office and in
         any other office or agency of the Company designated pursuant to
         Section 5.2 being herein sometimes collectively referred to as the
         "Note register") in which, subject to such reasonable regulations as
         it may prescribe, the Company shall provide for the registration of
         Notes and of transfers of Notes. Such register shall be in written
         form or in any form capable of being converted into written form
         within a reasonable period of time. The Trustee is hereby appointed
         "Note registrar" for the purpose of registering Notes and transfers of
         Notes as herein provided. The Company may appoint one or more
         co-registrars in accordance with Section 5.2.

                  Upon surrender for registration of transfer of any Note to
         the Note registrar or any co-registrar, and satisfaction of the
         requirements for such transfer set forth in this Section 2.5, the
         Company shall execute, and the Trustee shall authenticate and deliver,
         in the name of the designated transferee or transferees, one or more
         new Notes of any authorized denominations and of a like aggregate
         principal amount and bearing such restrictive legends as may be
         required by this Indenture.



                                     -12-
<PAGE>   17

                  Notes may be exchanged for other Notes of any authorized
         denominations and of a like aggregate principal amount, upon surrender
         of the Notes to be exchanged at any such office or agency. Whenever
         any Notes are so surrendered for exchange, the Company shall execute,
         and the Trustee shall authenticate and deliver, the Notes which the
         Noteholder making the exchange is entitled to receive, bearing
         registration numbers not contemporaneously outstanding.

                  All Notes presented or surrendered for registration of
         transfer or for exchange shall (if so required by the Company, the
         Trustee, the Note registrar or any co-registrar) be duly endorsed, or
         be accompanied by a written instrument or instruments of transfer in
         form satisfactory to the Company and duly executed, by the Noteholder
         thereof or his attorney-in-fact duly authorized in writing.

                  No service charge shall be charged to the Noteholder for any
         exchange or registration of transfer of Notes, but the Company may
         require payment of a sum sufficient to cover any tax, assessments or
         other governmental charges that may be imposed in connection
         therewith.

                  None of the Company, the Trustee, the Note registrar or any
         co-registrar shall be required to exchange or register a transfer of
         (a) any Notes for a period of fifteen (15) days next preceding any
         selection of Notes to be redeemed or (b) any Notes called for
         redemption or, if a portion of any Note is selected or called for
         redemption, such portion thereof selected or called for redemption or
         (c) any Notes surrendered for conversion or, if a portion of any Note
         is surrendered for conversion, such portion thereof surrendered for
         conversion or (d) any Notes, or a portion of any Note, surrendered for
         repurchase (and not withdrawn) in connection with a Repurchase Event.

                  All Notes issued upon any transfer or exchange of Notes in
         accordance with this Indenture shall be the valid obligations of the
         Company, evidencing the same debt, and entitled to the same benefits
         under this Indenture as the Notes surrendered upon such registration
         of transfer or exchange.

                  (b)    So long as the Notes are eligible for book-entry
         settlement with the Depositary, unless otherwise required by law, all
         Notes issued to QIBs pursuant to Rule 144A of the Securities Act to be
         traded on The Portal Market shall be represented by a Note in global
         form (the "Global Note") registered in the name of the Depositary or
         the nominee of the Depositary. The transfer and exchange of beneficial
         interests in the Global Note, which does not involve the issuance of a
         definitive Note, shall be effected through the Depositary (but not the
         Trustee or the Custodian) in accordance with this Indenture (including
         the restrictions on transfer set forth herein) and the procedures of
         the Depositary therefor.



                                     -13-
<PAGE>   18

                  Notes resold to persons who are not QIBs will be issued in
         definitive registered form and may not be represented by the Global
         Note. In addition, at any time at the request of a QIB that is a
         beneficial holder of an interest in the Global Note, such beneficial
         holder shall be entitled to obtain a definitive Note upon written
         request to the Trustee and the Custodian in accordance with the
         standing instructions and procedures existing between the Depositary
         and the Custodian for the issuance thereof. Upon receipt of any such
         request, the Trustee or the Custodian, at the direction of the
         Trustee, will cause, in accordance with the standing instructions and
         procedures existing between the Depositary and the Custodian, the
         aggregate principal amount of the Global Note to be reduced by the
         principal amount of the definitive Note issued upon such request to
         such beneficial holder and, following such reduction, the Company will
         execute and the Trustee will authenticate and deliver to such
         beneficial holder (or its nominee) a definitive Note or Notes in the
         appropriate aggregate principal amount in the name of such beneficial
         holder (or its nominee) and bearing such restrictive legends as may be
         required by this Indenture.

                  Any transfer of a beneficial interest in the Global Note
         which cannot be effected through book-entry settlement must be
         effected by the delivery to the transferee (or its nominee) of a
         definitive Note or Notes registered in the name of the transferee (or
         its nominee) on the books maintained by the Trustee in accordance with
         the transfer restrictions set forth herein. With respect to any such
         transfer, the Trustee or the Custodian, at the direction of the
         Trustee, will cause, in accordance with the standing instructions and
         procedures existing between the Depositary and the Custodian, the
         aggregate principal amount of the Global Note to be reduced by the
         principal amount of the beneficial interest in the Global Note being
         transferred and, following such reduction, the Company will execute
         and the Trustee will authenticate and deliver to the transferee (or
         such transferee's nominee, as the case may be), a Note or Notes in the
         appropriate aggregate principal amount in the name of such transferee
         (or its nominee) and bearing such restrictive legends as may be
         required by this Indenture.

                  (c)    So long as the Notes are eligible for book-entry
         settlement, unless otherwise required by law, upon any transfer of a
         definitive Note to a QIB in accordance with Rule 144A, unless
         otherwise requested by the transferor, and upon receipt of the
         definitive Note or Notes being so transferred, together with a
         certification from the transferor that the transferee is a QIB (or
         other evidence satisfactory to the Trustee), the Trustee shall make or
         direct the Custodian to make, an endorsement on the Global Note to
         reflect an increase in the aggregate principal amount of the Notes
         represented by the Global Note by the principal amount of the Note
         being transferred to the QIB, the Trustee shall cancel such definitive
         Note or Notes and cause, or direct the Custodian to cause, in
         accordance with the standing instructions and procedures existing
         between the Depositary and the Custodian, the aggregate principal
         amount of Notes represented by the Global Note to be increased
         accordingly; provided that no definitive Note, or portion thereof, in




                                     -14-
<PAGE>   19

         respect of which the Company or an Affiliate of the Company held any
         beneficial interest shall be included in the Global Note until such
         definitive Note is freely tradable in accordance with Rule 144(k);
         provided further that the Trustee shall authenticate and deliver Notes
         in definitive form upon any transfer of a beneficial interest in the
         Global Note to the Company or any Affiliate of the Company.

                  Upon any sale or transfer of a Note or the Common Stock
         issued upon conversion thereof that bears the restrictive legend set
         forth in Section 2.5(d) or Section 2.5(e), respectively, to an
         Institutional Accredited Investor (other than pursuant to a
         registration statement that has been declared effective under the
         Securities Act), such Institutional Accredited Investor shall, prior
         to such sale or transfer, furnish to the Company and/or the Trustee a
         signed letter containing representations and agreements relating to
         restrictions on transfer substantially in the form set forth in
         Exhibit B to this Indenture.

                  Any Global Note may be endorsed with or have incorporated in
         the text thereof such legends or recitals or changes not inconsistent
         with the provisions of this Indenture as may be required by the
         Custodian, the Depositary or by the National Association of Securities
         Dealers, Inc. in order for the Notes to be tradeable on The Portal
         Market or as may be required for the Notes to be tradeable on any
         other market developed for trading of securities pursuant to Rule 144A
         or required to comply with any applicable law or any regulation
         thereunder or with the rules and regulations of any securities
         exchange or automated quotation system upon which the Notes may be
         listed or traded or designated for issuance or to conform with any
         usage with respect thereto, or to indicate any special limitations or
         restrictions to which any particular Notes are subject.

                  (d)    Every Note that bears or is required under this 
         Section 2.5(d) to bear either of the legends set forth in this Section
         2.5(d) (together with any Common Stock issued upon conversion of the
         Notes and required to bear either of the legends set forth in Section
         2.5(e), collectively, the "Restricted Securities") shall be subject to
         the restrictions on transfer set forth in this Section 2.5(d)
         (including one of the legends set forth below), unless such
         restrictions on transfer shall be waived by written consent of the
         Company, and the holder of each such Restricted Security, by such
         holder's acceptance thereof, agrees to be bound by all such
         restrictions on transfer. As used in Sections 2.5(d) and 2.5(e), the
         term "transfer" encompasses any sale, pledge, transfer or other
         disposition whatsoever of any Restricted Security.

                  Until two (2) years after the original issuance date of any
         Note, any certificate evidencing such Note (and all securities issued
         in exchange therefor or substitution thereof, other than Common Stock,
         if any, issued upon conversion thereof which shall bear the legend set
         forth in Section 2.5(e), if applicable) shall bear a legend in
         substantially the following form (unless such Notes have been
         transferred pursuant to a registration statement that has been
         declared effective under the Securities Act (and 



                                     -15-

         which continues to be effective at the time of such transfer),
         pursuant to the exemption from registration provided by Rule 144 under
         the Securities Act, or unless otherwise agreed by the Company in
         writing, with notice thereof to the Trustee):

                  THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE
                  U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
                  ACT") OR ANY STATE SECURITIES LAWS, AND MAY NOT BE OFFERED OR
                  SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS
                  ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS
                  A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A
                  UNDER THE SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL
                  "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1), (2), (3)
                  OR (7) UNDER THE SECURITIES ACT) ("INSTITUTIONAL ACCREDITED
                  INVESTOR"); (2) AGREES THAT IT WILL NOT WITHIN TWO YEARS
                  AFTER THE ORIGINAL ISSUANCE OF THE NOTE EVIDENCED HEREBY
                  RESELL OR OTHERWISE TRANSFER THE NOTE EVIDENCED HEREBY OR THE
                  COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH NOTE EXCEPT (A)
                  TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED
                  INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
                  SECURITIES ACT, (C) TO AN INSTITUTIONAL ACCREDITED INVESTOR
                  THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO STATE STREET BANK
                  AND TRUST COMPANY, AS TRUSTEE, A SIGNED LETTER CONTAINING
                  CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE
                  RESTRICTIONS ON TRANSFER OF THE NOTE EVIDENCED HEREBY (THE
                  FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH TRUSTEE), (D)
                  PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE
                  144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (E) PURSUANT
                  TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE
                  UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE EFFECTIVE
                  AT THE TIME OF SUCH TRANSFER); AND (3) AGREES THAT IT WILL
                  DELIVER TO EACH PERSON TO WHOM THE NOTE EVIDENCED HEREBY IS
                  TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(E)
                  ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.
                  IN CONNECTION WITH ANY TRANSFER OF THE NOTE EVIDENCED HEREBY
                  WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE OF SUCH NOTE
                  (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(E)

                  ABOVE), THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH
                  ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER
                  AND SUBMIT THIS CERTIFICATE TO STATE STREET BANK AND TRUST
                  COMPANY, AS TRUSTEE. IF THE PROPOSED TRANSFER IS PURSUANT TO
                  CLAUSE 2(C) OR 2(D) ABOVE, THE HOLDER MUST, PRIOR TO SUCH
                  TRANSFER, FURNISH TO STATE STREET BANK AND TRUST COMPANY, AS
                  TRUSTEE, SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER
                  INFORMATION AS THE COMPANY MAY REASONABLY REQUIRE TO CONFIRM
                  THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION
                  FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
                  REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND WILL BE
                  REMOVED UPON THE EARLIER OF THE TRANSFER OF THE NOTE
                  EVIDENCED HEREBY PURSUANT TO CLAUSE 2(D) OR 2(E) ABOVE OR THE
                  EXPIRATION OF TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE
                  NOTE EVIDENCED HEREBY.

                  Any Note (or security issued in exchange or substitution
         therefor) as to which such restrictions on transfer shall have expired
         in accordance with their terms may, upon surrender of such Note for
         exchange to the Note registrar in accordance with the provisions of
         this Section 2.5, be exchanged for a new Note or Notes, of like tenor
         and aggregate principal amount, which shall not bear the restrictive
         legend required by this Section 2.5(d).

                  Notwithstanding any other provisions of this Indenture (other
         than the provisions set forth in this Section 2.5(d)), the Global Note
         may not be transferred as a whole or in part except by the Depositary
         to a nominee of the Depositary or by a nominee of the Depositary to
         the Depositary or another nominee of the Depositary or by the
         Depositary or any such nominee to a successor Depositary or a nominee
         of such successor Depositary.

                  The Depositary shall be a clearing agency registered under
         the Exchange Act. The Company initially appoints The Depository Trust
         Company to act as Depositary with respect to the Global Note.
         Initially, the Global Note shall be issued to the Depositary,
         registered in the name of Cede & Co., as the nominee of the
         Depositary, and deposited with the Trustee as custodian for Cede & Co.

                  If at any time the Depositary for the Global Note notifies
         the Company that it is unwilling or unable to continue as Depositary
         for such Note, the Company may appoint a successor Depositary with
         respect to such Note. If a successor Depositary for the Global Note is
         not appointed by the Company within ninety (90) days after the Company



                                     -17-

         receives such notice, the Company will execute, and the Trustee, upon
         receipt of an Officers' Certificate for the authentication and
         delivery of Notes, will authenticate and deliver, Notes in definitive
         form, in an aggregate principal amount equal to the principal amount
         of the Global Note, in exchange for the Global Note, and upon delivery
         of the Global Note to the Trustee the Global Note shall be canceled.

                  If a Note in certificated form is issued in exchange for any
         portion of a Global Note after the close of business on any record
         date at the office or agency where such exchange occurs and before the
         opening of business at such office or agency on the next succeeding
         interest payment date, interest will not be payable on such interest
         payment date in respect of such certificated Note, but will be payable
         on such interest payment date only with respect to the exchanged
         portion of the Global Note in accordance with the provisions of this
         Indenture.

                  Definitive Notes issued in exchange for all or a part of the
         Global Note pursuant to this Section 2.5(d) shall be registered in
         such names and in such authorized denominations as the Depositary,
         pursuant to instructions from its direct or indirect participants or
         otherwise, shall instruct the Trustee. Upon execution and
         authentication, the Trustee shall deliver such definitive Notes to the
         persons in whose names such definitive Notes are so registered.

                  At such time as all interests in the Global Note have been
         redeemed, converted, canceled, repurchased or transferred, the Global
         Note shall be, upon receipt thereof, canceled by the Trustee in
         accordance with standing procedures and instructions existing between
         the Depositary and the Custodian. At any time prior to such
         cancellation, if any interest in the Global Note is exchanged for
         definitive Notes, redeemed, converted, canceled, repurchased or
         transferred to a transferee who receives definitive Notes therefor or
         any definitive Note is exchanged or transferred for part of the Global
         Note, the principal amount of the Global Note shall, in accordance
         with the standing procedures and instructions existing between the
         Depositary and the Custodian, be appropriately reduced or increased,
         as the case may be, and an endorsement shall be made on the Global
         Note, by the Trustee or the Custodian, at the direction of the
         Trustee, to reflect such reduction or increase.

                  (e)    Until two (2) years after the original issuance date 
         of any Note, any stock certificate representing Common Stock issued
         upon conversion of such Note shall bear a legend in substantially the
         following form (unless such Common Stock has been sold pursuant to the
         exemption from registration provided by Rule 144 under the Securities
         Act or pursuant to a registration statement that has been declared
         effective under the Securities Act, and which continues to be
         effective at the time of such transfer, or such Common Stock has been
         issued upon conversion of Notes that have been transferred pursuant to
         a registration statement that has been declared effective under the

                  BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING

                  CONVERSION OF WHICH THE COMMON STOCK EVIDENCED HEREBY WAS

                  TRANSFER); (2) PRIOR TO ANY SUCH TRANSFER (OTHER THAN A

                  EFFECT OF THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON THE
                  EARLIER OF THE TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY
                  PURSUANT TO CLAUSE 1(D) OR 1(E) ABOVE OR THE EXPIRATION OF
                  TWO YEARS FROM THE ORIGINAL ISSUANCE OF THE NOTE UPON THE
                  CONVERSION OF WHICH THE COMMON STOCK EVIDENCED HEREBY WAS
                  ISSUED.

                  Any such Common Stock as to which such restrictions on
         transfer shall have expired in accordance with their terms may, upon
         surrender of the certificates representing such shares of Common Stock
         for exchange in accordance with the procedures of the transfer agent
         for the Common Stock, be exchanged for a new certificate or
         certificates for a like aggregate number of shares of Common Stock,
         which shall not bear the restrictive legend required by this Section
         2.5(e).

                  (f)    Any Note or Common Stock issued upon the conversion or
         exchange of a Note that, prior to the expiration of the holding period
         applicable to sales thereof under Rule 144(k) under the Securities Act
         (or any successor provision), is purchased or owned by the Company or
         any Affiliate thereof may not be resold by the Company or such
         Affiliate unless registered under the Securities Act or resold
         pursuant to an exemption from the registration requirements of the
         Securities Act in a transaction that results in such Notes or Common
         Stock, as the case may be, no longer being "restricted securities" (as
         defined under Rule 144).

                  (g)    Notwithstanding any provision of Section 2.5 to the
         contrary, in the event Rule 144(k) as promulgated under the Securities
         Act (or any successor rule) is amended to change the two-year period
         under Rule 144(k) (or the corresponding period under any successor
         rule), from and after receipt by the Trustee of the Officers'
         Certificate and Opinion of Counsel provided for in this Section
         2.5(g), (i) each reference in Section 2.5(d) to "two (2) years" and in
         the restrictive legend set forth in such paragraph to "TWO YEARS"
         shall be deemed for all purposes hereof to be references to such
         changed period, (ii) each reference in Section 2.5(e) to "two (2)
         years" and in the restrictive legend set forth in such paragraph to
         "TWO YEARS" shall be deemed for all purposes hereof to be references
         to such changed period and (iii) all corresponding references in the
         Notes and the restrictive legends thereon shall be deemed for all
         purposes hereof to be references to such changed period, provided that
         such changes shall not become effective if they are otherwise
         prohibited by, or would otherwise cause a violation of, the
         then-applicable federal securities laws. As soon as practicable after
         the Company has knowledge of the effectiveness of any such amendment
         to change the two-year period under Rule 144(k) (or the corresponding
         period under any successor rule), unless such changes would otherwise
         be prohibited by, or would otherwise cause a violation of, the
         then-applicable securities law, the Company shall provide to the
         Trustee



                                     -20-
<PAGE>   25

         an Officers' Certificate and Opinion of Counsel informing the Trustee
         of the effectiveness of such amendment and the effectiveness of the
         foregoing changes to Sections 2.5(d) and 2.5(e) and the Notes. The
         provisions of this Section 2.5(g) will not be effective until such
         time as the Opinion of Counsel and Officers' Certificate have been
         received by the Trustee hereunder. This Section 2.5(g) shall apply to
         successive amendments to Rule 144(k) (or any successor rule) changing
         the holding period thereunder.

         Section 2.6     Mutilated, Destroyed, Lost or Stolen Notes. In case 
any Note shall become mutilated or be destroyed, lost or stolen, the Company in
its discretion may execute, and upon its request the Trustee or an
authenticating agent appointed by the Trustee shall authenticate and deliver, a
new Note, bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated Note, or in lieu of and in substitution for the
Note so destroyed, lost or stolen. In every case the applicant for a
substituted Note shall furnish to the Company, to the Trustee and, if
applicable, to such authenticating agent such security or indemnity as may be
required by them to save each of them harmless for any loss, liability, cost or
expense caused by or connected with such substitution, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company, to
the Trustee and, if applicable, to such authenticating agent evidence to their
satisfaction of the destruction, loss or theft of such Note and of the
ownership thereof.

         The Trustee or such authenticating agent may authenticate any such
substituted Note and deliver the same upon the receipt of such security or
indemnity as the Trustee, the Company and, if applicable, such authenticating
agent may require. Upon the issuance of any substituted Note, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses connected
therewith. In case any Note which has matured or is about to mature or has been
called for redemption or is about to be converted into Common Stock shall
become mutilated or be destroyed, lost or stolen, the Company may, instead of
issuing a substitute Note, pay or authorize the payment of or convert or
authorize the conversion of the same (without surrender thereof except in the
case of a mutilated Note), as the case may be, if the applicant for such
payment or conversion shall furnish to the Company, to the Trustee and, if
applicable, to such authenticating agent such security or indemnity as may be
required by them to save each of them harmless for any loss, liability, cost or
expense caused by or connected with such substitution, and, in case of
destruction, loss or theft, evidence satisfactory to the Company, the Trustee
and, if applicable, any paying agent or conversion agent of the destruction,
loss or theft of such Note and of the ownership thereof.

         Every substitute Note issued pursuant to the provisions of this
Section 2.6 by virtue of the fact that any Note is destroyed, lost or stolen
shall constitute an additional contractual obligation of the Company, whether
or not the destroyed, lost or stolen Note shall be found at any time, and shall
be entitled to all the benefits of (but shall be subject to all the limitations
set forth in) this Indenture equally and proportionately with any and all other
Notes duly issued hereunder. To the



                                     -21-
<PAGE>   26

extent permitted by law, all Notes shall be held and owned upon the express
condition that the foregoing provisions are exclusive with respect to the
replacement or payment or conversion of mutilated, destroyed, lost or stolen
Notes and shall preclude any and all other rights or remedies notwithstanding
any law or statute existing or hereafter enacted to the contrary with respect
to the replacement or payment or conversion of negotiable instruments or other
securities without their surrender.

         Section 2.7     Temporary Notes. Pending the preparation of definitive
Notes, the Company may execute and the Trustee or an authenticating agent
appointed by the Trustee shall, upon written request of the Company,
authenticate and deliver temporary Notes (printed or lithographed). Temporary
Notes shall be issuable in any authorized denomination, and substantially in
the form of the definitive Notes but with such omissions, insertions and
variations as may be appropriate for temporary Notes, all as may be determined
by the Company. Every such temporary Note shall be executed by the Company and
authenticated by the Trustee or such authenticating agent upon the same
conditions and in substantially the same manner, and with the same effect, as
the definitive Notes. Without unreasonable delay the Company will execute and
deliver to the Trustee or such authenticating agent definitive Notes (other
than in the case of Notes in global form) and thereupon any or all temporary
Notes (other than any the Global Note) may be surrendered in exchange therefor,
at each office or agency maintained by the Company pursuant to Section 5.2 and
the Trustee or such authenticating agent shall authenticate and deliver in
exchange for such temporary Notes an equal aggregate principal amount of
definitive Notes. Such exchange shall be made by the Company at its own expense
and without any charge therefor. Until so exchanged, the temporary Notes shall
in all respects be entitled to the same benefits and subject to the same
limitations under this Indenture as definitive Notes authenticated and
delivered hereunder.

         Section 2.8     Cancellation of Notes Paid, Etc. All Notes surrendered
for the purpose of payment, redemption, repurchase, conversion, exchange or
registration of transfer, shall, if surrendered to the Company or any paying
agent or any Note registrar or any conversion agent, be surrendered to the
Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall
be promptly canceled by it, and no Notes shall be issued in lieu thereof except
as expressly permitted by any of the provisions of this Indenture. Upon written
instructions of the Company, the Trustee shall destroy canceled Notes and,
after such destruction, shall deliver a certificate of such destruction to the
Company. If the Company shall acquire any of the Notes, such acquisition shall
not operate as a redemption or satisfaction of the indebtedness represented by
such Notes unless and until the same are delivered to the Trustee for
cancellation.

                              REDEMPTION OF NOTES



                                     -22-
<PAGE>   27

         Section 3.1     Redemption Prices. The Company may, at its option, 
redeem all or from time to time any part of the Notes on any date prior to
maturity, upon notice as set forth in Section 3.2, and at the optional
redemption prices set forth in the form of Note attached as Exhibit A hereto,
together with accrued interest, if any, to, but excluding, the date fixed for
redemption, provided, however, that no such redemption shall be effected before
April 2, 2002.

         Section 3.2     Notice of Redemption; Selection of Notes. In case the
Company shall desire to exercise the right to redeem all or, as the case may
be, any part of the Notes pursuant to Section 3.1, it shall fix a date for
redemption, and it, or at its request (which must be received by the Trustee at
least ten (10) Business Days prior to the date the Trustee is requested to give
notice as described below unless a shorter period is agreed to by the Trustee),
the Trustee in the name of and at the expense of the Company, shall mail or
cause to be mailed a notice of such redemption at least thirty (30) and not
more than sixty (60) days prior to the date fixed for redemption to the holders
of Notes so to be redeemed as a whole or in part at their last addresses as the
same appear on the Note register (provided that if the Company shall give such
notice, it shall also give such notice, and notice of the Notes to be redeemed,
to the Trustee). Such mailing shall be by first class mail. The notice if
mailed in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not the holder receives such notice. In any case,
failure to give such notice by mail or any defect in the notice to the holder
of any Note designated for redemption as a whole or in part shall not affect
the validity of the proceedings for the redemption.

         Each such notice of redemption shall specify the aggregate principal
amount of Notes to be redeemed, the CUSIP number or numbers of such Notes, the
date fixed for redemption, the redemption price at which Notes are to be
redeemed, the place or places of payment, that payment will be made upon
presentation and surrender of such Notes, that interest accrued to, but
excluding, the date fixed for redemption will be paid as specified in said
notice, and that on and after said date interest thereon or on the portion
thereof to be redeemed will cease to accrue. Such notice shall also state the
current Conversion Price and the date on which the right to convert such Notes
or portions thereof into Common Stock will expire. If fewer than all the Notes
are to be redeemed, the notice of redemption shall identify the Notes to be
redeemed. In case any Note is to be redeemed in part only, the notice of
redemption shall state the portion of the principal amount thereof to be
redeemed and shall state that on and after the date fixed for redemption, upon
surrender of such Note, a new Note or Notes in principal amount equal to the
unredeemed portion thereof will be issued.

         On or prior to the redemption date specified in the notice of
redemption given as provided in this Section, the Company will deposit with the
Trustee or with one or more paying agents (or, if the Company is acting as its
own paying agent, set aside, segregate and hold in trust as provided in Section
5.4) an amount of money sufficient to redeem on the redemption date all the
Notes (or portions thereof) so called for redemption (other than those
theretofore surrendered for conversion into Common Stock) at the appropriate
redemption price, together with accrued



                                     -23-
<PAGE>   28

interest to, but excluding, the date fixed for redemption; provided that if
such payment is made on the redemption date it must be received by the Trustee
or paying agent, as the case may be, by 10:00 a.m. New York City time, on such
date. If any Note called for redemption is converted pursuant hereto, any money
deposited with the Trustee or any paying agent or so segregated and held in
trust for the redemption of such Note shall be paid to the Company upon its
request, or, if then held by the Company shall be discharged from such trust.

         If fewer than all the Notes are to be redeemed, the Company will give
the Trustee written notice in the form of an Officers' Certificate not fewer
than forty (40) days (or such shorter period of time as may be acceptable to
the Trustee) prior to the redemption date as to the aggregate principal amount
of Notes to be redeemed. If fewer than all the Notes are to be redeemed, the
Trustee shall select the Notes or portions thereof to be redeemed (in principal
amounts of $1,000 or integral multiples thereof), by lot or, in its discretion,
on a pro rata basis, or by a method the Trustee considers fair and appropriate
(as long as such method is not prohibited by the rules of any United States
national securities exchange or of an established automated over-the-counter
trading market in the United States on which the Notes are then listed). If any
Note selected for partial redemption is converted in part after such selection,
the converted portion of such Note shall be deemed (so far as is possible) to
be the portion to be selected for redemption. The Notes (or portions thereof)
so selected shall be deemed duly selected for redemption for all purposes
hereof, notwithstanding that any such Note is converted as a whole or in part
before the mailing of the notice of redemption.

         Upon any redemption of less than all Notes, the Company and the
Trustee may (but need not) treat as outstanding any Notes surrendered for
conversion during the period of fifteen (15) days next preceding the mailing of
a notice of redemption and may (but need not) treat as not outstanding any Note
authenticated and delivered during such period in exchange for the unconverted
portion of any Note converted in part during such period.

         Section 3.3     Payment of Notes Called for Redemption. If notice of
redemption has been given as above provided, the Notes or portion of Notes with
respect to which such notice has been given shall, unless converted into Common
Stock pursuant to the terms hereof, become due and payable on the date and at
the place or places stated in such notice at the applicable redemption price,
together with interest accrued to, but excluding, the date fixed for
redemption, and on and after said date (unless the Company shall default in the
payment of such Notes at the redemption price, together with interest accrued
to, but excluding, said date) interest on the Notes or portion of Notes so
called for redemption shall cease to accrue and such Notes shall cease, after
the close of business on the Business Day next preceding the date fixed for
redemption, to be convertible into Common Stock and, except as provided in
Sections 8.5 and 13.4, to be entitled to any benefit or security under this
Indenture, and the holders thereof shall have no right in respect of such Notes
except the right to receive the redemption price thereof and unpaid interest
to, but excluding, the date fixed for redemption. On presentation and surrender
of such Notes at a place of payment in said notice specified, the said Notes or
the specified portions



                                     -24-
<PAGE>   29

thereof to be redeemed shall be paid and redeemed by the Company at the
applicable redemption price, together with interest accrued thereon to, but
excluding, the date fixed for redemption; provided that, if the applicable
redemption date is an interest payment date, the semi-annual payment of
interest becoming due on such date shall be payable to the holders of such
Notes registered as such on the relevant record date subject to the terms and
provisions of Section 2.3 hereof.

         Upon presentation of any Note redeemed in part only, the Company shall
execute and the Trustee shall authenticate and deliver to the holder thereof,
at the expense of the Company, a new Note or Notes, of authorized
denominations, in principal amount equal to the unredeemed portion of the Notes
so presented.

         Notwithstanding the foregoing, the Trustee shall not redeem any Notes
or mail any notice of optional redemption during the continuance of a default
in payment of interest or premium on the Notes or of any Event of Default of
which, in the case of any Event of Default other than under Section 7.1(a), (b)
or (e), a Responsible Officer of the Trustee has knowledge. If any Note called
for redemption shall not be so paid upon surrender thereof for redemption, the
principal and premium, if any, shall, until paid or duly provided for, bear
interest from the date fixed for redemption at the rate borne by the Note and
such Note shall remain convertible into Common Stock until the principal and
premium, if any, shall have been paid or duly provided for.

         Section 3.4     Conversion Arrangement on Call for Redemption. In
connection with any redemption of Notes, the Company may arrange for the
purchase and conversion of any Notes not converted prior to the expiration of
such conversion right by an agreement with one or more investment bankers or
other purchasers to purchase such Notes by paying to the Trustee in trust for
the Noteholders, on or before the date fixed for redemption, an amount not less
than the applicable redemption price, together with interest accrued to the
date fixed for redemption, of such Notes. Notwithstanding anything to the
contrary contained in this Article III, the obligation of the Company to pay
the redemption price of such Notes, together with interest accrued to, but
excluding, the date fixed for redemption, shall be deemed to be satisfied and
discharged to the extent such amount is so paid by such purchasers. If such an
agreement is entered into, a copy of which, certified as true and correct by
the Secretary or Assistant Secretary of the Company will be filed with the
Trustee prior to the date fixed for redemption, any Notes not duly surrendered
for conversion by the holders thereof may, at the option of the Company, be
deemed, to the fullest extent permitted by law, acquired by such purchasers
from such holders and (notwithstanding anything to the contrary contained in
Article XV) surrendered by such purchasers for conversion, all as of
immediately prior to the close of business on the date fixed for redemption
(and the right to convert any such Notes shall be deemed to have been extended
through such time), subject to payment of the above amount as aforesaid. At the
direction of the Company, the Trustee shall hold and dispose of any such amount
paid to it in the same manner as it would monies deposited with it by the
Company for the redemption of Notes. Without the Trustee's prior written
consent, no arrangement between the Company and such purchasers for

the purchase and conversion of any Notes shall increase or otherwise affect any
of the powers, duties, responsibilities or obligations of the Trustee as set
forth in this Indenture, and the Company agrees to indemnify the Trustee from,
and hold it harmless against, any loss, liability or expense arising out of or
in connection with any such arrangement for the purchase and conversion of any
Notes between the Company and such purchasers, including the costs and expenses
incurred by the Trustee in the defense of any claim or liability arising out of
or in connection with the exercise or performance of any of its powers, duties,
responsibilities or obligations under this Indenture.

                                   ARTICLE IV

                             SUBORDINATION OF NOTES

         Section 4.1     Agreement of Subordination. The Company covenants and
agrees, and each holder of Notes issued hereunder by his acceptance thereof
likewise covenants and agrees, that all Notes shall be issued subject to the
provisions of this Article IV; and each person holding any Note, whether upon
original issue or upon transfer, assignment or exchange thereof, accepts and
agrees to be bound by such provisions.

         The payment of the principal of, premium, if any, and interest on all
Notes (including, but not limited to, the redemption price or repurchase price
with respect to the Notes to be redeemed or repurchased, as provided in this
Indenture) issued hereunder shall, to the extent and in the manner hereinafter
set forth, be subordinated to the prior payment in full, in cash or in such
other form of payment as may be acceptable to the holders of Senior
Indebtedness, of all Senior Indebtedness, whether outstanding at the date of
this Indenture or thereafter incurred or created.

         No provision of this Article IV shall prevent the occurrence of any
default or Event of Default hereunder.

         Section 4.2     Payments to Noteholders. No payment (including 
pursuant to any redemption or repurchase of Notes) shall be made with respect
to the principal of, or premium, if any, or interest (including Liquidated
Damages, if any) on the Notes, except payments and distributions made by the
Trustee as permitted by Section 4.6, if:

                  (1)    a default in the payment of principal, premium, if
         any, or interest or other payment due on Designated Senior
         Indebtedness occurs and is continuing beyond any applicable period of
         grace; or

                  (2)    any other default occurs and is continuing with
         respect to Designated Senior Indebtedness that then permits holders of
         the Designated Senior Indebtedness as to which such default related to
         accelerate its maturity and the Trustee and the Company 



                                     -26-
<PAGE>   31

         receive a notice of such default (a "Payment Blockage Notice") from a
         representative of Designated Senior Indebtedness or a holder of
         Designated Senior Indebtedness or the Company.

         The Company may and shall resume payments on the Notes (1) in the case
of a payment default, on the date upon which such default is cured or waived or
ceases to exist, and (2) in the case of a nonpayment default with respect to
Designated Senior Indebtedness, on the earlier of the date on which the
nonpayment default is cured or waived or ceases to exist or 179 days pass after
the date on which the applicable Payment Blockage Notice is received.

         No new period of payment blockage may be commenced pursuant to a
Payment Blockage Notice unless (A) at least 365 days shall have elapsed since
the first day of effectiveness of the immediately prior Payment Blockage Notice
and (B) all scheduled payments of principal, premium, if any, and interest on
the Notes that have come due have been paid in full in cash, or in such other
form of payment as may be acceptable to the holders of the Notes. No default
(whether or not such event of default is on the same issue of Designated Senior
Indebtedness) that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice.

         In addition, in the event of any acceleration of the Notes because of
an Event of Default, no payment or distribution (including with respect to any
redemption or repurchase of the Notes) shall be made to the Trustee or any
holder of Notes with respect to the principal of, premium, if any, or interest
(including Liquidated Damages, if any) on the Notes, except payments and
distributions made by the Trustee as permitted by Section 4.6, until all Senior
Indebtedness has been paid in full in cash or other payment satisfactory to the
holders of Senior Indebtedness or such acceleration is rescinded in accordance
with the terms of this Indenture. If payment of the Notes is accelerated
because of an Event of Default, the Company shall promptly notify holders of
Senior Indebtedness of the acceleration.

         Notwithstanding the foregoing, in the event that the Trustee or any
holder of Notes receives any payment or distribution of assets of the Company
of any kind in contravention of any term of this Indenture, whether in cash,
property or securities, including, without limitation, by way of setoff or
otherwise, before all Senior Indebtedness is paid in full, in cash or such
other form of payment as may be acceptable to the holders of Senior
Indebtedness, then such payment or distribution shall be held by the recipient
or recipients in trust for the benefit of, and shall immediately be paid over
or delivered to, the holders of Senior Indebtedness or their respective
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any Senior Indebtedness
may have been issued, as their respective interests may appear, as calculated
by the Company, for application to the payment of all Senior Indebtedness
remaining unpaid to the extent necessary to make payment in full, in cash or
such other form of payment as may be acceptable to the holders of Senior
Indebtedness, of all Senior Indebtedness remaining unpaid, after giving effect
to any concurrent payment or distribution, or provision therefor, to or for the
holders of such Senior Indebtedness.

         Nothing in this Section 4.2 shall apply to claims of, or payments to,
the Trustee pursuant to Section 8.6. This Section 4.2 shall be subject to the
further provisions of Section 4.6.

         Section 4.3     Bankruptcy and Dissolution, Etc. Upon any payment by
the Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to creditors upon any dissolution,
winding-up, liquidation or reorganization of the Company, whether voluntary or
involuntary or in bankruptcy, insolvency, receivership or other proceedings,
all amounts due or to become due upon all Senior Indebtedness shall first be
paid in full, in cash or in such other form of payment as may be acceptable to
the holders of Senior Indebtedness, before any payment is made on account of
the principal or premium, if any, and interest on the Notes (except payments
made pursuant to Article XIII from monies deposited with the Trustee pursuant
thereto prior to the happening of such dissolution, winding-up, liquidation or
reorganization or bankruptcy, insolvency, receivership or other such
proceedings); and upon any such dissolution, winding-up, liquidation or
reorganization or bankruptcy, insolvency, receivership or other such
proceedings, any payment by the Company, or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
which the holders of the Notes or the Trustee under this Indenture would be
entitled, except for the provision of this Article IV, shall (except as
aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other person making such payment or distribution,
or by the holders of the Notes or by the Trustee under this Indenture if
received by them or it, directly to the holders of Senior Indebtedness (pro
rata to such holders on the basis of the respective amounts of Senior
Indebtedness held by such holders, or as otherwise required by law or a court
order) or their respective representative or representatives, or to the trustee
or trustees under any indenture pursuant to which any instruments evidencing
any Senior Indebtedness may have been issued, as their respective interests may
appear, to the extent necessary to pay all Senior Indebtedness in full in cash
or in such other form of payment as may be acceptable to the holders of Senior
Indebtedness after giving effect to any concurrent payment or distribution to
or for the holders of Senior Indebtedness, before any payment or distribution
is made to the holders of the Notes or to the Trustee under this Indenture.

         Notwithstanding the foregoing, in the event that the Trustee or any
holder of Notes receives any payment or distribution of assets of the Company
of any kind in contravention of any term of this Indenture, whether in cash,
property or securities, including, without limitation, by way of setoff or
otherwise, before all Senior Indebtedness is paid in full, in cash or such
other form of payment as may be acceptable to the holders of Senior
Indebtedness, then such payment or distribution shall be held by the recipient
or recipients in trust for the benefit of, and shall immediately be paid over
or delivered to, the holders of Senior Indebtedness or their respective
representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any Senior Indebtedness
may have been issued, as their respective interests may appear, as calculated
by the Company, for application to the payment of all Senior Indebtedness
remaining unpaid to the extent necessary to make payment in full, in cash



                                     -28-
<PAGE>   33

or such other form of payment as may be acceptable to the holders of Senior
Indebtedness, of all Senior Indebtedness remaining unpaid, after giving effect
to any concurrent payment or distribution, or provision therefor, to or for the
holders of such Senior Indebtedness.

         For purposes of Section 4.2 hereof and this Section 4.3, the words
"cash, property or securities" shall not be deemed to include shares of stock
of the Company as reorganized or readjusted, or securities of the Company or
any other corporation provided for by a plan of reorganization or readjustment,
the payment of which is subordinated (at least to the extent provided in this
Article IV with respect to the Notes) to the payment of all Senior Indebtedness
which may at the time be outstanding; provided that (i) the Senior Indebtedness
is assumed by the new corporation, if any, resulting from such reorganization
or adjustment, and (ii) the rights of the holders of Senior Indebtedness (other
than leases which are not assumed by the Company or by the new corporation, as
the case may be) are not, without the consent of such holders, altered by such
reorganization or readjustment. The consolidation of the Company with, or the
merger of the Company into, another corporation or the liquidation or
dissolution of the Company following the conveyance or transfer of its property
as an entirety, or substantially as an entirety, to another corporation upon
the terms and conditions provided for in Article XII shall not be deemed a
dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 4.3 if such other corporation shall, as a part of such consolidation,
merger, conveyance or transfer, comply with the conditions stated in Article
XII.

         Nothing in this Section 4.3 shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 8.6. This Section 4.3 shall be subject
to the further provisions of Section 4.6.

         Section 4.4     Subrogation of Notes. Subject to the payment in full
in cash or in such other form of payment as may be acceptable to the holders of
Senior Indebtedness of all Senior Indebtedness, the rights of the holders of
the Notes shall be subrogated to the extent of the payments or distributions
made to the holders of such Senior Indebtedness pursuant to the provisions of
this Article IV (equally and ratably with the holders of all indebtedness of
the Company which by its express terms is subordinated to other indebtedness of
the Company to substantially the same extent as the Notes are subordinated and
is entitled to like rights of subrogation) to the rights of the holders of
Senior Indebtedness to receive payments or distributions of cash, property or
securities of the Company applicable to the Senior Indebtedness until the
principal of, and premium, if any, and interest on the Notes shall be paid in
full; and, for the purposes of such subrogation, no payments or distributions
to the holders of the Senior Indebtedness of any cash, property or securities
to which the holders of the Notes or the Trustee would be entitled except for
the provisions of this Article IV, and no payment over pursuant to the
provisions of this Article IV, to or for the benefit of the holders of Senior
Indebtedness by holders of the Notes or the Trustee, shall, as between the
Company, its creditors other than holders of Senior Indebtedness, and the
holders of the Notes, be deemed to be a payment by the Company to or on account
of the Senior Indebtedness; and no payments or distributions of cash, property
or securities to or for the benefit of the holders of the Notes pursuant to the
subrogation



                                     -29-
<PAGE>   34

provisions of this Article IV, which would otherwise have been paid to the
holders of Senior Indebtedness shall be deemed to be a payment by the Company
to or for the account of the Notes. It is understood that the provisions of
this Article IV are and are intended solely for the purposes of defining the
relative rights of the holders of the Notes, on the one hand, and the holders
of the Senior Indebtedness, on the other hand.

         Nothing contained in this Article IV or elsewhere in this Indenture or
in the Notes is intended to or shall impair, as among the Company, its
creditors other than the holders of Senior Indebtedness, and the holders of the
Notes, the obligation of the Company, which is absolute and unconditional, to
pay to the holders of the Notes the principal of, and premium, if any, and
interest on the Notes as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect the relative
rights of the holders of the Notes and creditors of the Company other than the
holders of the Senior Indebtedness, nor shall anything herein or therein
prevent the Trustee or the holder of any Note from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture,
subject to the rights, if any, under this Article IV of the holders of Senior
Indebtedness in respect of cash, property or securities of the Company received
upon the exercise of any such remedy.

         Upon any payment or distribution of assets of the Company referred to
in this Article IV, the Trustee, subject to the provisions of Section 8.1, and
the holders of the Notes shall be entitled to rely upon any order or decree
made by any court of competent jurisdiction in which such bankruptcy,
dissolution, winding-up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidating trustee,
agent or other person making such payment or distribution, delivered to the
Trustee or to the holders of the Notes, for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all
other facts pertinent thereto or to this Article IV.

         Section 4.5     Authorization by Noteholders. Each holder of a Note by
his acceptance thereof authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to effectuate the subordination
provided in this Article IV and appoints the Trustee his attorney-in-fact for
any and all such purposes.

         Section 4.6     Notice to Trustee. The Company shall give written 
notice to the Trustee of the issuance of any Designated Senior Indebtedness. In
addition, the Company shall give prompt written notice in the form of an
Officers' Certificate to a Responsible Officer of the Trustee and to any paying
agent of any fact known to the Company which would prohibit the making of any
payment of monies to or by the Trustee or any paying agent in respect of the
Notes pursuant to the provisions of this Article IV. Notwithstanding the
provisions of this Article IV or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any Senior
Indebtedness or of any default or event of default with



                                     -30-
<PAGE>   35

respect to any Senior Indebtedness or of any other facts which would prohibit
the making of any payment of monies to or by the Trustee in respect of the
Notes pursuant to the provisions of this Article IV, unless and until a
Responsible Officer of the Trustee shall have received written notice thereof
at the Corporate Trust Office from the Company (in the form of an Officers'
Certificate) or a holder or holders of Senior Indebtedness or from any trustee
thereof who shall have been certified by the Company or otherwise established
to the reasonable satisfaction of the Trustee to be such holder or trustee; and
before the receipt of any such written notice, the Trustee, subject to the
provisions of Section 8.1, shall be entitled in all respects to assume that no
such facts exist; provided that if on a date at least two (2) Business Days
prior to the date upon which by the terms hereof any such monies may become
payable for any purpose (including, without limitation, the payment of the
principal of, or premium, if any, or interest on any Note), the Trustee shall
not have received with respect to such monies the notice provided for in this
Section 4.6, then, anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to receive such monies and to
apply the same to the purpose for which they were received, and shall not be
affected by any notice to the contrary which may be received by it on or after
such prior date.

         Notwithstanding anything to the contrary hereinbefore set forth,
nothing shall prevent (a) any payment by the Company or the Trustee to the
Noteholders of amounts in connection with a redemption of Notes if (i) notice
of such redemption has been given to the Noteholders pursuant to Article III
prior to the receipt by the Trustee of written notice as aforesaid, and (ii)
such notice of redemption is given not earlier than sixty (60) days before the
redemption date, (b) any payment by the Company or the Trustee to the
Noteholders of amounts in connection with a repurchase of Notes if (i) notice
of such repurchase has been given pursuant to Article XVI prior to the receipt
by the Trustee of written notice as aforesaid, and (ii) such notice of
repurchase is given not earlier than forty (40) days before the repurchase
date, or (c) any payment by the Trustee to the Noteholders of monies deposited
with it pursuant to Section 13.1.

         The Trustee, subject to the provisions of Section 8.1, shall be
entitled to rely on the delivery to it of a written notice by a person
representing himself to be a holder of Senior Indebtedness (or a trustee on
behalf of such holder) to establish that such notice has been given by a holder
of Senior Indebtedness or a trustee on behalf of any such holder or holders. In
the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article IV, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such person, the extent to which such person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such person under this Article IV, and if such evidence is not furnished the
Trustee may defer any payment to such person pending judicial determination as
to the right of such person to receive such payment.

         Section 4.7     Trustee's Relation to Senior Indebtedness. The Trustee
and any agent of the Company or the Trustee in its individual capacity shall be
entitled to all the rights set forth in this Article IV in respect of any
Senior Indebtedness at any time held by it, to the same extent as any other
holder of Senior Indebtedness, and nothing in Section 8.13 or elsewhere in this
Indenture shall deprive the Trustee or any such agent of any of its rights as
such holder. Nothing in this Article IV shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 8.6.

         With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article IV, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness and, subject to the
provisions of Section 4.2 and Section 8.1, the Trustee shall not be liable to
any holder of Senior Indebtedness if it shall pay over or deliver to holders of
Notes, the Company or any other person money or assets to which any holder of
Senior Indebtedness shall be entitled by virtue of this Article IV or
otherwise.

         Section 4.8     No Impairment of Subordination. No right of any 
present or future holder of any Senior Indebtedness to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the Company
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof which any such holder may have or otherwise be charged with.

         Section 4.9     Certain Conversions and Repurchases Deemed Payment. 
For the purposes of this Article IV only, (1) the issuance and delivery of
junior securities upon conversion of Notes in accordance with Article XV or
upon repurchase of the Notes by the Company in the event of a Repurchase Event
in accordance with Article XVI shall not be deemed to constitute a payment or
distribution on account of the principal of (or premium, if any) or interest on
Notes or on account of the purchase or other acquisition of Notes, and (2) the
payment, issuance or delivery of cash (including cash paid for fractional
shares upon conversion of a Note or upon repurchase of a Note upon a Repurchase
Event), property or securities (other than junior securities) upon conversion
of a Note or upon repurchase of a Note on a Repurchase Event shall be deemed to
constitute payment on account of the principal of such Note. For the purposes
of this Section, the term "junior securities" means (a) shares of any stock of
any class of the Company and (b) securities of the Company which are
subordinated in right of payment to all Senior Indebtedness which may be
outstanding at the time of issuance or delivery of such securities to
substantially the same extent as, or to a greater extent than, the Notes are so
subordinated as provided in this Article. Nothing contained in this Article or
elsewhere in this Indenture or in the Notes is intended to or shall impair, as
among the Company, its creditors other than holders of Senior Indebtedness and
the holders of the Notes, the right, which is 



                                     -32-
<PAGE>   37

absolute and unconditional, of the holder of any Note to convert such Note in
accordance with Article XV.

         Section 4.10    Article Applicable to Paying Agents. If at any time
any paying agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term Trustee as used in this Article
IV shall (unless the context shall otherwise require) be construed as extending
to and including such paying agent within its meaning as fully for all intents
and purposes as if such paying agent were named in this Article in addition to
or in place of the Trustee; provided, however, that the first sentence of
Section 4.5 shall not apply to the Company or any Affiliate of the Company if
it or such Affiliate acts as paying agent.

                                   ARTICLE V

                      PARTICULAR COVENANTS OF THE COMPANY

         Section 5.1     Payment of Principal, Premium and Interest. The 
Company covenants and agrees that it will duly and punctually pay or cause to
be paid the principal of and premium, if any, and interest (including
Liquidated Damages, if any) on each of the Notes at the places, at the
respective times and in the manner provided herein and in the Notes. Each
installment of interest on the Notes due on any semi-annual interest payment
date may be paid by mailing checks for the interest payable to or upon the
written order of the holders of Notes entitled thereto as they shall appear on
the registry books of the Company, provided that, with respect to any holder of
Notes with an aggregate principal amount equal to or in excess of $2,000,000,
at the request of such holder in writing to the Company, interest on such
holder's Notes shall be paid by wire transfer in immediately available funds to
any bank located in the United States in accordance with the wire transfer
instructions supplied by such holder from time to time to the Trustee and
paying agent (if different from Trustee) at least two days prior to the
applicable record date.

         Section 5.2     Maintenance of Office or Agency. The Company will 
maintain in the Borough of Manhattan, The City of New York, an office or agency
where the Notes may be surrendered for registration of transfer or exchange or
for presentation for payment or for conversion, redemption or repurchase and
where notices and demands to or upon the Company in respect of the Notes and
this Indenture may be served. The Company will give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency not designated or appointed by the Trustee. If at any time the Company
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office or the
office or agency of the Trustee in the Borough of Manhattan, The City of New
York.

         The Company may also from time to time designate one or more other
offices or agencies



                                     -33-
<PAGE>   38

where the Notes may be presented or surrendered for any or all such purposes
and may from time to time rescind such designations; provided that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, The
City of New York, for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change
in the location of any such other office or agency.

         The Company hereby initially designates the Trustee as paying agent,
Note registrar, Custodian and conversion agent and the Corporate Trust Office
and the office or agency of the Trustee in the Borough of Manhattan, The City
of New York (which initially shall be State Street Bank and Trust Company,
N.A., an Affiliate of the Trustee, located at 61 Broadway, 15th Floor, New
York, New York 10006 (Attention: Corporate Trust Department--SportsLine USA,
Inc.-- 5% Convertible Subordinated Notes due 2006)) as one such office or
agency of the Company for each of the aforesaid purposes.

         So long as the Trustee is the Note registrar, the Trustee agrees to
mail, or cause to be mailed, the notices set forth in Section 8.10(a) and the
third paragraph of Section 8.11.

         Section 5.3     Appointments to Fill Vacancies in Trustee's Office. 
The Company, whenever necessary to avoid or fill a vacancy in the office of
Trustee, will appoint, in the manner provided in Section 8.10, a Trustee, so
that there shall at all times be a Trustee hereunder.

         Section 5.4     Provisions as to Paying Agent.

                  (a)    If the Company shall appoint a paying agent other than
         the Trustee or if the Trustee shall appoint such a paying agent, it
         will cause such paying agent to execute and deliver to the Trustee an
         instrument in which such agent shall agree with the Trustee, subject
         to the provisions of this Section 5.4:

                         (1)       that it will hold all sums held by it as
                  such agent for the payment of the principal of and premium,
                  if any, or interest on the Notes (whether such sums have been
                  paid to it by the Company or by any other obligor on the
                  Notes) in trust for the benefit of the holders of the Notes;

                         (2)       that it will give the Trustee notice of any
                  failure by the Company (or by any other obligor on the Notes)
                  to make any payment of the principal of and premium, if any,
                  or interest on the Notes when the same shall be due and
                  payable; and

                         (3)       that at any time during the continuance of
                  an Event of Default, upon request of the Trustee, it will
                  forthwith pay to the Trustee all sums so held in trust.

                  The Company shall, on or before each due date of the
         principal of, premium, if any, or interest on the Notes, deposit with
         the paying agent a sum sufficient to pay such principal, premium, if
         any, or interest, and (unless such paying agent is the Trustee) the

         Notes when the same shall become due and payable.

                  (c)    Anything in this Section 5.4 to the contrary

(to the extent that it may lawfully do so) that it shall not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage

know of any default or Event of Default that occurred during such period. If
they do, such Officers' Certificate shall describe the default or Event of
Default and its status.

         Section 5.9     Further Instruments and Acts. Upon request of the 
Trustee, the Company will execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more

                             DEFAULTS AND REMEDIES

         Section 7.1     Events of Default. In case one or more of the 
following Events of Default (whatever the reason for such Event of Default and

         Subsidiary to make any payment at maturity, including any applicable
         grace period, in respect of Indebtedness of, or guaranteed or assumed
         by, the Company or any Significant Subsidiary, in a principal amount
         then outstanding in excess of U.S. $15,000,000, and the continuance of
         such failure for a period of thirty (30) days after there shall have
         been given, by registered or certified mail, to the Company by the
         Trustee or to the Company and the Trustee by the holders of not less
         than 25% in aggregate principal amount of the Notes then outstanding,

         results in the acceleration of Indebtedness in a principal amount then
         outstanding in excess of U.S. $15,000,000, and such Indebtedness shall
         not have been discharged or such acceleration shall not have been

                                     -39-
<PAGE>   44

         case or other proceeding seeking liquidation, reorganization or other
         relief with respect to itself or its debts under any bankruptcy,
         insolvency or other similar law now or hereafter in effect or seeking
         the appointment of a trustee, receiver, liquidator, custodian or other
         similar official of it or any substantial part of its property, or
         shall consent to any such relief or to the appointment of or taking
         possession by any such official in an involuntary case or other
         proceeding commenced against it, or shall make a general assignment
         for the benefit of creditors, or shall fail generally to pay its debts
         as they become due; or

                  (j)    an involuntary case or other proceeding shall be
         commenced against the Company or any Significant Subsidiary seeking
         liquidation, reorganization or other relief with respect to it or its
         debts under any bankruptcy, insolvency or other similar law now or
         hereafter in effect or seeking the appointment of a trustee, receiver,
         liquidator, custodian or other similar official of it or any
         substantial part of its property, and such involuntary case or other
         proceeding shall remain undismissed and unstayed for a period of
         ninety (90) consecutive days;

then, and in each and every such case (other than an Event of Default specified
in Section 7.1(i) or (j) with respect to the Company), unless the principal of
all of the Notes shall have already become due and payable, either the Trustee
or the holders of not less than 25% in aggregate principal amount of the Notes
then outstanding hereunder determined in accordance with Section 9.4, by notice
in writing to the Company (and to the Trustee if given by Noteholders), may
declare the principal of and premium, if any, on all the Notes and the interest
accrued thereon to be due and payable immediately, and upon any such
declaration the same shall become and shall be immediately due and payable,
anything in this Indenture or in the Notes contained to the contrary
notwithstanding. If an Event of Default specified in Section 7.1(i) or (j)
occurs and is continuing with respect to the Company, the principal of all the
Notes and the interest accrued thereon shall be immediately due and payable.
This provision, however, is subject to the conditions that if, at any time
after the principal of the Notes shall have been so declared due and payable,
and before any judgment or decree for the payment of the monies due shall have
been obtained or entered as hereinafter provided, the Company shall pay or
shall deposit with the Trustee a sum sufficient to pay all matured installments
of interest upon all Notes and the principal of and premium, if any, on any and
all Notes which shall have become due otherwise than by acceleration (with
interest on overdue installments of interest (to the extent that payment of
such interest is enforceable under applicable law) and on such principal and
premium, if any, at the rate borne by the Notes, to the date of such payment or
deposit) and amounts due to the Trustee pursuant to Section 8.6, and if any and
all defaults under this Indenture, other than the nonpayment of principal of
and premium, if any, and accrued interest on Notes which shall have become due
by acceleration, shall have been cured or waived pursuant to Section 7.7, then
and in every such case the holders of a majority in aggregate principal amount
of the Notes then outstanding, by written notice to the Company and to the
Trustee, may waive all defaults or Events of Default and rescind and annul such
declaration and its consequences; but no such waiver or rescission and
annulment shall extend to or shall affect any



                                     -40-
<PAGE>   45

subsequent default or Event of Default, or shall impair any right consequent
thereon. The Company shall notify the Responsible Officer of the Trustee,
promptly upon becoming aware thereof, of any default or Event of Default and
shall deliver to the Trustee a statement specifying such default or Event of
Default and the action the Company has taken, is taking or proposes to take
with respect thereto.

         In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of such waiver or rescission and annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such
case the Company, the holders of Notes, and the Trustee shall be restored
respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the Company, the holders of Notes, and the Trustee shall
continue as though no such proceeding had been instituted.

         Section 7.2     Payments of Notes on Default; Suit Therefor. The 
Company covenants that (a) in case default shall be made in the payment by the
Company of any installment of interest upon any of the Notes as and when the
same shall become due and payable, and such default shall have continued for a
period of thirty (30) days, or (b) in case default shall be made in the payment
of the principal of or premium, if any, on any of the Notes as and when the
same shall have become due and payable, whether at maturity of the Notes or in
connection with any redemption or repurchase, by declaration under this
Indenture or otherwise, then, upon demand of the Trustee, the Company will pay
to the Trustee, for the benefit of the holders of the Notes, the whole amount
that then shall have become due and payable on all such Notes for principal and
premium, if any, or interest, or both, as the case may be, with interest upon
the overdue principal and premium, if any, and (to the extent that payment of
such interest is enforceable under applicable law) upon the overdue
installments of interest at the rate borne by the Notes; and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including reasonable compensation to the Trustee, its
agents, attorneys and counsel, and any expenses or liabilities incurred by the
Trustee hereunder other than through its negligence or bad faith. Until such
demand by the Trustee, the Company may pay the principal of and premium, if
any, and interest on the Notes to the registered holders, whether or not the
Notes are overdue.

         In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor on the Notes
and collect in the manner provided by law out of the property of the Company or
any other obligor on the Notes wherever situated the monies adjudged or decreed
to be payable.

         In the case there shall be pending proceedings for the bankruptcy or
for the reorganization



                                     -41-
<PAGE>   46

of the Company or any other obligor on the Notes under Title 11 of the United
States Code, or any other applicable law, or in case a receiver, assignee or
trustee in bankruptcy or reorganization, liquidator, sequestrator or similar
official shall have been appointed for or taken possession of the Company or
such other obligor, the property of the Company or such other obligor, or in
the case of any other judicial proceedings relative to the Company or such
other obligor upon the Notes, or to the creditors or property of the Company or
such other obligor, the Trustee, irrespective of whether the principal of the
Notes shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand
pursuant to the provisions of this Section 7.2, shall be entitled and
empowered, by intervention in such proceedings or otherwise, to file and prove
a claim or claims for the whole amount of principal, premium, if any, and
interest owing and unpaid in respect of the Notes, and, in case of any judicial
proceedings, to file such proofs of claim and other papers or documents and to
take such other actions as it may deem necessary or advisable in order to have
the claims of the Trustee and of the Noteholders allowed in such judicial
proceedings relative to the Company or any other obligor on the Notes, its or
their creditors, or its or their property, and to collect and receive any
monies or other property payable or deliverable on any such claims, and to
distribute the same after the deduction of any amounts due the Trustee under
Section 8.6; and any receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, custodian or similar official is hereby authorized
by each of the Noteholders to make such payments to the Trustee, and, in the
event that the Trustee shall consent to the making of such payments directly to
the Noteholders, to pay to the Trustee any amount due it for reasonable
compensation, expenses, advances and disbursements, including agents and
counsel fees incurred by it up to the date of such distribution. To the extent
that such payment of reasonable compensation, expenses, advances and
disbursements out of the estate in any such proceedings shall be denied for any
reason, payment of the same shall be secured by a lien on, and shall be paid
out of, any and all distributions, dividends, monies, securities and other
property which the holders of the Notes may be entitled to receive in such
proceedings, whether in liquidation or under any plan of reorganization or
arrangement or otherwise.

         All rights of action and of asserting claims under this Indenture, or
under any of the Notes, may be enforced by the Trustee without the possession
of any of the Notes, or the production thereof on any trial or other proceeding
relative thereto, and any such suit or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the holders of the Notes.

         In any proceedings brought by the Trustee (and in any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the
holders of the Notes, and it shall not be necessary to make any holders of the
Notes parties to any such proceedings.

         Section 7.3     Application of Monies Collected by Trustee. Any monies
collected by the Trustee pursuant to this Article VII shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution
of such monies, upon presentation of the several Notes, and stamping thereon
the payment, if only partially paid, and upon surrender thereof, if fully paid:

                  First: To the payment of all amounts due the Trustee under 
         Section 8.6;

                  Second: Subject to the provisions of Article IV, in case the

         unpaid, to the payment of interest on the Notes in default in the
         order of the maturity of the installments of such interest, with
         interest (to the extent that such interest has been collected by the
         Trustee) upon the overdue installments of interest at the rate borne
         by the Notes, such payments to be made ratably to the persons entitled
         thereto;

                  Third: Subject to the provisions of Article IV, in case the
         principal of the outstanding Notes shall have become due, by
         declaration or otherwise, and be unpaid, to the payment of the whole
         amount then owing and unpaid upon the Notes for principal and premium,
         if any, and interest, with interest on the overdue principal and
         premium, if any, and (to the extent that such interest has been
         collected by the Trustee) upon overdue installments of interest at the
         rate borne by the Notes; and in case such monies shall be insufficient
         to pay in full the whole amounts so due and unpaid upon the Notes,
         then to the payment of such principal and premium, if any, and
         interest without preference or priority of principal and premium, if
         any, over interest, or of interest over principal and premium, if any,
         or of any installment of interest over any other installment of
         interest, or of any Note over any other Note, ratably to the aggregate
         of such principal and premium, if any, and accrued and unpaid
         interest; and

                  Fourth: Subject to the provisions of Article IV, to the 
         payment of the remainder, if any, to the Company or any other person
         lawfully entitled thereto.

         Section 7.4     Proceedings by Noteholder. No holder of any Note shall
have any right by virtue of or by availing of any provision of this Indenture
to institute any suit, action or proceeding in equity or at law upon or under
or with respect to this Indenture, or for the appointment of a receiver,
trustee, liquidator, custodian or other similar official, or for any other
remedy hereunder, unless such holder previously shall have given to the Trustee
written notice of an Event of Default and of the continuance thereof, as
hereinbefore provided, and unless also the holders of not less than 25% in
aggregate principal amount of the Notes then outstanding shall have made
written request upon the Trustee to institute such action, suit or proceeding
in its own name as Trustee hereunder and shall have offered to the Trustee such
indemnity as may be reasonably satisfactory to the Trustee against the costs,
expenses and liabilities to be incurred therein or thereby, and the Trustee for
sixty (60) days after its receipt of such notice, request and



                                     -43-
<PAGE>   48

offer of indemnity, shall have neglected or refused to institute any such
action, suit or proceeding and no direction inconsistent with such written
request shall have been given to the Trustee pursuant to Section 7.7; it being
understood and intended, and being expressly covenanted by the taker and holder
of every Note with every other taker and holder and the Trustee, that no one or
more holders of Notes shall have any right in any manner whatever by virtue of
or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other holder of Notes, or to obtain or seek to
obtain priority over or preference to any other such holder, or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all holders of Notes (except as otherwise
provided herein). For the protection and enforcement of this Section 7.4, each
and every Noteholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

         Notwithstanding any other provision of this Indenture and any
provision of any Note, the right of any holder of any Note to receive payment
of the principal of and premium, if any, and interest on such Note, on or after
the respective due dates expressed in such Note, or to institute suit for the
enforcement of any such payment on or after such respective dates against the
Company shall not be impaired or affected without the consent of such holder.

         Anything in this Indenture or the Notes to the contrary
notwithstanding, the holder of any Note, without the consent of either the
Trustee or the holder of any other Note, in his own behalf and for his own
benefit, may enforce, and may institute and maintain any proceeding suitable to
enforce, his rights of conversion as provided herein.

         Section 7.5     Proceedings by Trustee. In case of an Event of Default
the Trustee may in its discretion proceed to protect and enforce the rights
vested in it by this Indenture by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any of such rights,
either by suit in equity or by action at law or by proceeding in bankruptcy or
otherwise, whether for the specific enforcement of any covenant or agreement
contained in this Indenture or in aid of the exercise of any power granted in
this Indenture, or to enforce any other legal or equitable right vested in the
Trustee by this Indenture or by law.

         Section 7.6     Remedies Cumulative and Continuing. Except as provided
in the last paragraph of Section 2.6, all powers and remedies given by this
Article VII to the Trustee or to the Noteholders shall, to the extent permitted
by law, be deemed cumulative and not exclusive of any thereof or of any other
powers and remedies available to the Trustee or the holders of the Notes, by
judicial proceedings or otherwise, to enforce the performance or observance of
the covenants and agreements contained in this Indenture, and no delay or
omission of the Trustee or of any holder of any of the Notes to exercise any
right or power accruing upon any default or Event of Default occurring and
continuing as aforesaid shall impair any such right or power, or shall be
construed to be a waiver of any such default or any acquiescence therein; and,
subject to the provisions of Section 7.4, every power and remedy given by this
Article VII or by law to the Trustee or to the Noteholders may be exercised
from time to time, and as often as shall be



                                     -44-
<PAGE>   49

deemed expedient, by the Trustee or by the Noteholders.

         Section 7.7     Direction of Proceedings and Waiver of Defaults by
Majority of Noteholders. The holders of a majority in aggregate principal
amount of the Notes at the time outstanding determined in accordance with
Section 9.4 shall have the right to direct the time, method, and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee; provided, however, that (a) such
direction shall not be in conflict with any rule of law or with this Indenture,
and (b) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction. The holders of not less than a
majority in aggregate principal amount of the Notes at the time outstanding
determined in accordance with Section 9.4 may on behalf of the holders of all
of the Notes waive any past default or Event of Default hereunder and its
consequences except (i) a default in the payment of interest or premium, if
any, on, or the principal of, the Notes when due, (ii) a failure by the Company
to convert any Notes into Common Stock or (iii) a default in respect of a
covenant or provisions hereof which under Article XI cannot be modified or
amended without the consent of the holders of all Notes then outstanding. Upon
any such waiver the Company, the Trustee and the holders of the Notes shall be
restored to their former positions and rights hereunder; but no such waiver
shall extend to any subsequent or other default or Event of Default or impair
any right consequent thereon. Whenever any default or Event of Default
hereunder shall have been waived as permitted by this Section 7.7, said default
or Event of Default shall for all purposes of the Notes and this Indenture be
deemed to have been cured and to be not continuing; but no such waiver shall
extend to any subsequent or other default or Event of Default or impair any
right consequent thereon.

         Section 7.8     Notice of Defaults. The Trustee shall, within ninety
(90) days after the occurrence of a default, mail to all Noteholders, as the
names and addresses of such holders appear upon the Note register, notice of
all defaults known to a Responsible Officer, unless such defaults shall have
been cured or waived before the giving of such notice; and provided that,
except in the case of default in the payment of the principal of, or premium,
if any, or interest on any of the Notes, including without limiting the
generality of the foregoing any default in the payment of any Repurchase Price
or in the payment of any amount due in connection with any redemption of Notes,
then in any such event the Trustee shall be protected in withholding such
notice if and so long as a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determines that the withholding of such
notice is in the interests of the Noteholders.

         Section 7.9     Undertaking to Pay Costs. All parties to this 
Indenture agree, and each holder of any Note by his acceptance thereof shall be
deemed to have agreed, that any court may, in its discretion, require, in any
suit for the enforcement of any right or remedy under this Indenture, or in any
suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of
such suit and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the



                                     -45-
<PAGE>   50

claims or defenses made by such party litigant; provided that the provisions of
this Section 7.9 shall not apply to any suit instituted by the Trustee, to any
suit instituted by any Noteholder, or group of Noteholders, holding in the
aggregate more than 10% in principal amount of the Notes at the time
outstanding determined in accordance with Section 9.4, or to any suit
instituted by any Noteholder for the enforcement of the payment of the
principal of or premium, if any, or interest on any Note (including, but not
limited to, the redemption price or repurchase price with respect to the Notes
being redeemed or repurchased as provided in this Indenture) on or after the
due date expressed in such Note or to any suit for the enforcement of the right
to convert any Note in accordance with the provisions of Article XV.

         Section 7.10    Delay or Omission Not Waiver. No delay or omission of
the Trustee or of any holder of any Note to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or any acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
holders of Notes may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the holders of Notes, as the case may
be.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE
 
         Section 8.1     Duties and Responsibilities of Trustee. The Trustee, 
prior to the occurrence of an Event of Default and after the curing or waiver
of all Events of Default which may have occurred, undertakes to perform such
duties and only such duties as are specifically set forth in this Indenture. In
case an Event of Default has occurred (which has not been cured or waived) the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

         No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct, except that

                  (a)    prior to the occurrence of an Event of Default and 
         after the curing or waiving of all Events of Default which may have
         occurred:

                         (1)       the duties and obligations of the Trustee
                  shall be determined solely by the express provisions of this
                  Indenture and, after it has been qualified thereunder, the
                  Trust Indenture Act, and the Trustee shall not be liable
                  except for the performance of such duties and obligations as
                  are specifically set forth in this Indenture and no implied
                  covenants or obligations shall be read into this Indenture



                                     -46-
<PAGE>   51

                  and the Trust Indenture Act against the Trustee; and

                         (2)       in the absence of bad faith and willful
                  misconduct on the part of the Trustee, the Trustee may
                  conclusively rely, as to the truth of the statements and the
                  correctness of the opinions expressed therein, upon any
                  certificates or opinions furnished to the Trustee and
                  conforming to the requirements of this Indenture; but, in the
                  case of any such certificates or opinions which by any
                  provisions hereof are specifically required to be furnished
                  to the Trustee, the Trustee shall be under a duty to examine
                  the same to determine whether or not they conform to the
                  requirements of this Indenture;

                  (b)    the Trustee shall not be liable for any error of 
         judgment made in good faith by a Responsible Officer or Officers of
         the Trustee, unless it shall be provided that the Trustee was
         negligent in ascertaining the pertinent facts;

                  (c)    the Trustee shall not be liable to any Noteholder with
         respect to any action taken or omitted to be taken by it in good faith
         in accordance with the direction of the holders of not less than a
         majority in principal amount of the Notes at the time outstanding
         determined as provided in Section 9.4 relating to the time, method and
         place of conducting any proceeding for any remedy available to the
         Trustee, or exercising any trust or power conferred upon the Trustee,
         under this Indenture; and

                  (d)    whether or not therein provided, every provision of
         this Indenture relating to the conduct or affecting the liability of,
         or affording protection to, the Trustee shall be subject to the
         provisions of this Section.

                  None of the provisions contained in this Indenture shall
require the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise
of any of its rights or powers, if there is reasonable ground for believing
that the repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it.

         Section 8.2     Reliance on Documents, Opinions, Etc. Except as 
otherwise provided in Section 8.1:

                  (a)    the Trustee may rely and shall be protected in acting
         upon any resolution, certificate, statement, instrument, opinion,
         report, notice, request, consent, order, bond, note, coupon or other
         paper or document believed by it in good faith to be genuine and to
         have been signed or presented by the proper party or parties;

                  (b)    any request, direction, order or demand of the Company
         mentioned herein shall be sufficiently evidenced by an Officers'
         Certificate (unless other evidence in



                                     -47-
<PAGE>   52

         respect thereof be herein specifically prescribed); and any resolution
         of the Board of Directors may be evidenced to the Trustee by a copy
         thereof certified by the Secretary or an Assistant Secretary of the
         Company;

                  (c)    the Trustee may consult with counsel and any advice of
         such counsel or Opinion of Counsel shall be full and complete
         authorization and protection in respect of any action taken or omitted
         by it hereunder in good faith and in accordance with such advice or
         Opinion of Counsel;

                  (d)    the Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Indenture at the
         request, order or direction of any of the Noteholders pursuant to the
         provisions of this Indenture, unless such Noteholders shall have
         offered to the Trustee reasonable security or indemnity against the
         costs, expenses and liabilities which may be incurred therein or
         thereby;

                  (e)    the Trustee shall not be bound to make any 
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture or other paper or document,
         but the Trustee, in its discretion, may make such further inquiry or
         investigation into such facts or matters as it may see fit, and, if
         the Trustee shall determine to make such further inquiry or
         investigation, it shall be entitled to examine the books, records and
         premises of the Company, personally or by agent or attorney; provided,
         however, that if the payment within a reasonable time to the Trustee
         of the costs, expenses or liabilities likely to be incurred by it in
         the making of such investigation is, in the opinion of the Trustee,
         not reasonably assured to the Trustee by the security afforded to it
         by the terms of this Indenture, the Trustee may require indemnity
         reasonably satisfactory to the Trustee from the Noteholders against
         such expenses or liability as a condition to so proceeding; the
         reasonable expenses of every such examination shall be paid by the
         Company or, if paid by the Trustee or any predecessor Trustee, shall
         be repaid by the Company upon demand; and

                  (f)    the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys and the Trustee shall not be responsible
         for any misconduct or negligence on the part of any agent or attorney
         appointed by it with due care hereunder.

In no event shall the Trustee be liable for any consequential loss or damage of
any kind whatsoever (including but not limited to lost profits), even if the
Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action other than through the Trustee's willful
misconduct or gross negligence.

         Section 8.3     No Responsibility for Recitals, Etc. The recitals 
contained herein and in



                                     -48-
<PAGE>   53

the Notes (except in the Trustee's certificate of authentication) shall be
taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Notes. The Trustee shall not be accountable for the use or application by the
Company of any Notes or the proceeds of any Notes authenticated and delivered
by the Trustee in conformity with the provisions of this Indenture.

         Section 8.4     Trustee, Paying Agents, Conversion Agents or Registrar
May Own Notes. The Trustee, any paying agent, any conversion agent or Note
registrar, in its individual or any other capacity, may become the owner or
pledgee of Notes with the same rights it would have if it were not Trustee,
paying agent, conversion agent or Note registrar.

         Section 8.5     Monies to Be Held in Trust. Subject to the provisions
of Section 13.4, all monies received by the Trustee shall, until used or
applied as herein provided, be held in trust for the purposes for which they
were received. Money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. The Trustee
shall be under no liability for interest on any money received by it hereunder
except as may be agreed from time to time by the Company and the Trustee.

         Section 8.6     Compensation and Expenses of Trustee. The Company 
covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, reasonable compensation for all services rendered by it
hereunder in any capacity (which shall not be limited by any provision of law
in regard to the compensation of a trustee of an express trust), and the
Company will pay or reimburse the Trustee upon its request for all reasonable
expenses, disbursements and advances reasonably incurred or made by the Trustee
in accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its agents and
counsel and of all persons not regularly in its employ) except any such
expense, disbursement or advance as may arise from its negligence, willful
misconduct or bad faith. The Company also covenants to indemnify the Trustee in
any capacity under this Indenture and its agents and any authenticating agent
for, and to hold them harmless against, any loss, liability or expense incurred
without negligence, willful misconduct or bad faith on the part of the Trustee
or such agent or authenticating agent, as the case may be, and arising out of
or in connection with the acceptance or administration of this trust or in any
other capacity hereunder, including the costs and expenses of defending
themselves against any claim of liability in the premises. The obligations of
the Company under this Section 8.6 to compensate or indemnify the Trustee and
to pay or reimburse the Trustee for expenses, disbursements and advances shall
be secured by a lien prior to that of the Notes upon all property and funds
held or collected by the Trustee as such, except, subject to the effect of
Sections 4.3 and 7.6, funds held in trust herewith for the benefit of the
holders of particular Notes prior to the date of the accrual of such unpaid
compensation or indemnifiable claim. The obligation of the Company under this
Section shall survive the satisfaction and discharge of this Indenture. The
indemnification provided in this Section 8.6 shall extend to the officers,
directors, agents and employees of the Trustee.



                                     -49-

<PAGE>   54
         When the Trustee and its agents and any authenticating agent incur
expenses or render services after an Event of Default specified in Section
7.1(i) or (j) occurs, the expenses and the compensation for the services are
intended to constitute expenses of administration under any bankruptcy,
insolvency or similar laws.

         Section 8.7     Officers' Certificate as Evidence. Except as otherwise
provided in Section 8.1, whenever in the administration of the provisions of
this Indenture the Trustee shall deem it necessary or desirable that a matter
be proved or established prior to taking or omitting any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence, willful misconduct, recklessness
and bad faith on the part of the Trustee, be deemed to be conclusively proved
and established by an Officers' Certificate delivered to the Trustee, and such
Officers' Certificate, in the absence of negligence, willful misconduct,
recklessness and bad faith on the part of the Trustee, shall be full warrant to
the Trustee for any action taken or omitted by it under the provisions of this
Indenture upon the faith thereof.

         Section 8.8     Conflicting Interests of Trustee. After qualification
under the Trust Indenture Act, if the Trustee has or shall acquire a
conflicting interest within the meaning of the Trust Indenture Act, the Trustee
shall either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to the provisions of, the Trust Indenture Act and this
Indenture.

         Section 8.9     Eligibility of Trustee. There shall at all times be a
Trustee hereunder which shall be a person that is eligible pursuant to the
Trust Indenture Act to act as such and has a combined capital and surplus
(together with its corporate parent) of at least $50,000,000. If such person
publishes reports of condition at least annually, pursuant to law or to the
requirements of any supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such person shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

         Section 8.10    Resignation or Removal of Trustee.

                  (a)    The Trustee may at any time resign by giving written
         notice of such resignation to the Company and by mailing notice
         thereof to the holders of Notes at their addresses as they shall
         appear on the Note register. Upon receiving such notice of
         resignation, the Company shall promptly appoint a successor trustee by
         written instrument, in duplicate, executed by order of the Board of
         Directors, one copy of which



                                     -50-
<PAGE>   55

         instrument shall be delivered to the resigning Trustee and one copy to
         the successor trustee. If no successor trustee shall have been so
         appointed and have accepted appointment sixty (60) days after the
         mailing of such notice of resignation to the Noteholders, the
         resigning Trustee may petition any court of competent jurisdiction for
         the appointment of a successor trustee, or any Noteholder who has been
         a bona fide holder of a Note or Notes for at least six months may,
         subject to the provisions of Section 7.9, on behalf of himself and all
         others similarly situated, petition any such court for the appointment
         of a successor trustee. Such court may thereupon, after such notice,
         if any, as it may deem proper and prescribe, appoint a successor
         trustee.

                  (b)    In case at any time any of the following shall occur:

                         (1)       the Trustee shall fail to comply with 
                  Section 8.8 within a reasonable time after written request
                  therefor by the Company or by any Noteholder who has been a
                  bona fide holder of a Note or Notes for at least six months,
                  or

                         (2)       the Trustee shall cease to be eligible in
                  accordance with the provisions of Section 8.9 and shall fail
                  to resign after written request therefor by the Company or by
                  any such Noteholder, or

                         (3)       the Trustee shall become incapable of 
                  acting, or shall be adjudged a bankrupt or insolvent, or a
                  receiver of the Trustee or of its property shall be
                  appointed, or any public officer shall take charge or control
                  of the Trustee or of its property or affairs for the purpose
                  of rehabilitation, conservation or liquidation,

         then, in any such case, the Company may by a Board resolution remove
         the Trustee and appoint a successor trustee by written instrument, in
         duplicate, executed by order of the Board of Directors, one copy of
         which instrument shall be delivered to the Trustee so removed and one
         copy to the successor trustee, or, subject to the provisions of
         Section 7.9, any Noteholder who has been a bona fide holder of a Note
         or Notes for at least six months may, on behalf of himself and all
         others similarly situated, petition any court of competent
         jurisdiction for the removal of the Trustee and the appointment of a
         successor trustee. Such court may thereupon, after such notice, if
         any, as it may deem proper and prescribe, remove the Trustee and
         appoint a successor trustee.

                  (c)    The holders of a majority in aggregate principal 
         amount of the Notes at the time outstanding may at any time remove the
         Trustee and nominate a successor trustee which shall be deemed
         appointed as successor trustee unless within ten (10) days after
         notice to the Company of such nomination the Company objects thereto,
         in which case the Trustee so removed or any Noteholder, upon the terms
         and conditions and otherwise as in Section 8.10(a) provided, may
         petition any court of competent jurisdiction for an



                                     -51-

         appointment of a successor trustee.

                  (d)    Any resignation or removal of the Trustee and 
         appointment of a successor trustee pursuant to any of the provisions
         of this Section 8.10 shall become effective upon acceptance of
         appointment by the successor trustee as provided in Section 8.11.

         Section 8.11    Acceptance by Successor Trustee. Any successor trustee
appointed as provided in Section 8.10 shall execute, acknowledge and deliver to
the Company and to its predecessor trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, duties and obligations of its predecessor hereunder, with like effect
as if originally named as trustee herein; but, nevertheless, on the written
request of the Company or of the successor trustee, the trustee ceasing to act
shall, upon payment of any amounts then due it pursuant to the provisions of
Section 8.6, execute and deliver an instrument transferring to such successor
trustee all the rights and powers of the trustee so ceasing to act. Upon
request of any such successor trustee, the Company shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming
to such successor trustee all such rights and powers. Any trustee ceasing to
act shall, nevertheless, retain a lien upon all property and funds held or
collected by such trustee as such, except for funds held in trust for the
benefit of holders of particular Notes, to secure any amounts then due it
pursuant to the provisions of Section 8.6.

         No successor trustee shall accept appointment as provided in this
Section 8.11 unless at the time of such acceptance such successor trustee shall
be qualified under the provisions of Section 8.8 and be eligible under the
provisions of Section 8.9.

         Upon acceptance of appointment by a successor trustee as provided in
this Section 8.11, each of the Company and the former trustee shall mail or
cause to be mailed notice of the succession of such trustee hereunder to the
holders of Notes at their addresses as they shall appear on the Note register.
If the Company fails to mail such notice within ten (10) days after acceptance
of appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company.

         Section 8.12    Succession by Merger, Etc. Any corporation or other 
entity into which the Trustee may be merged or converted or with which it may
be consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any corporation or
other entity succeeding to all or substantially all of the corporate trust
business of the Trustee (including the trust created by this Indenture), shall
be the successor to the Trustee hereunder without the execution or filing of
any paper or any further act on the part of any of the parties hereto, provided
that in the case of any corporation succeeding to all or substantially all of
the corporate trust business of the Trustee such corporation shall be qualified
under the provisions of Section 8.8 and eligible under the provisions of
Section 8.9.



                                     -52-
<PAGE>   57

         In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture, any of the Notes shall have been
authenticated but not delivered, any such successor to the Trustee may adopt
the certificate of authentication of any predecessor trustee or authenticating
agent appointed by such predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to the Trustee or an authenticating agent
appointed by such successor trustee may authenticate such Notes either in the
name of any predecessor trustee hereunder or in the name of the successor
trustee; and in all such cases such certificates shall have the full force
which it is anywhere in the Notes or in this Indenture provided that the
certificate of the Trustee shall have; provided, however, that the right to
adopt the certificate of authentication of any predecessor Trustee or to
authenticate Notes in the name of any predecessor Trustee shall apply only to
its successor or successors by merger, conversion or consolidation.

         Section 8.13    Limitation on Rights of Trustee as Creditor. If and
when the Trustee shall be or become a creditor of the Company (or any other
obligor upon the Notes), after qualification under the Trust Indenture Act, the
Trustee shall be subject to the provisions of the Trust Indenture Act regarding
the collection of the claims against the Company (or any such other obligor).

                                   ARTICLE IX

                           CONCERNING THE NOTEHOLDERS

         Section 9.1     Action by Noteholders. Whenever in this Indenture it
is provided that the holders of a specified percentage in aggregate principal
amount of the Notes may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other
action), the fact that at the time of taking any such action, the holders of
such specified percentage have joined therein may be evidenced (a) by any
instrument or any number of instruments of similar tenor executed by
Noteholders in person or by agent or proxy appointed in writing, or (b) by the
record of the holders of Notes voting in favor thereof at any meeting of
Noteholders duly called and held in accordance with the provisions of Article
X, or (c) by a combination of such instrument or instruments and any such
record of such a meeting of Noteholders. Whenever the Company or the Trustee
solicits the taking of any action by the holders of the Notes, the Company or
the Trustee may fix in advance of such solicitation, a date as the record date
for determining holders entitled to take such action. The record date shall be
not more than fifteen (15) days prior to the date of commencement of
solicitation of such action.

         Section 9.2     Proof of Execution by Noteholders. Subject to the
provisions of Sections 8.1, 8.2 and 10.5, proof of the execution of any
instrument by a Noteholder or his agent or proxy shall be sufficient if made in
accordance with such reasonable rules and regulations as may be



                                     -53-
<PAGE>   58

prescribed by the Trustee or in such manner as shall be satisfactory to the
Trustee. The holding of Notes shall be proved by the Note register or by a
certificate of the Note registrar. The record of any Noteholders' meeting shall
be proved in the manner provided in Section 10.6.

         Section 9.3     Who Are Deemed Absolute Owners. The Company, the
Trustee, any authenticating agent, any paying agent, any conversion agent and
any Note registrar may deem the person in whose name such Note shall be
registered upon the Note register to be, and may treat him as, the absolute
owner of such Note (whether or not such Note shall be overdue and
notwithstanding any notation of ownership or other writing thereon) for the
purpose of receiving payment of or on account of the principal of, premium, if
any, and interest on such Note, for conversion of such Note and for all other
purposes; and neither the Company nor the Trustee nor any paying agent nor any
conversion agent nor any Note registrar shall be affected by any notice to the
contrary. All such payments so made to any holder for the time being, or upon
his order, shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for monies payable upon any
such Note.

         Section 9.4     Company-Owned Notes Disregarded. In determining 
whether the holders of the requisite aggregate principal amount of Notes have
concurred in any direction, consent, waiver or other action under this
Indenture, Notes which are owned by the Company or any other obligor on the
Notes or by any person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company or any other obligor
on the Notes shall be disregarded and deemed not to be outstanding for the
purpose of any such determination; provided that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, consent, waiver or other action only Notes which a Responsible
Officer knows are so owned shall be so disregarded. Notes so owned which have
been pledged in good faith may be regarded as outstanding for the purposes of
this Section 9.4 if the pledgee shall establish to the satisfaction of the
Trustee the pledgee's right to vote such Notes and that the pledgee is not the
Company, any other obligor on the Notes or a person directly or indirectly
controlling or controlled by or under direct or indirect common control with
the Company or any such other obligor. In the case of a dispute as to such
right, any decision by the Trustee taken upon the advice of counsel shall be
full protection to the Trustee. Upon request of the Trustee, the Company shall
furnish to the Trustee promptly an Officers' Certificate listing and
identifying all Notes, if any, known by the Company to be owned or held by or
for the account of any of the above described persons; and, subject to Section
8.1, the Trustee shall be entitled to accept such Officers' Certificate as
conclusive evidence of the facts therein set forth and of the fact that all
Notes not listed therein are outstanding for the purpose of any such
determination.

         Section 9.5     Revocation of Consents; Future Holders Bound. At any 
time prior to (but not after) the evidencing to the Trustee, as provided in
Section 9.1, of the taking of any action by the holders of the percentage in
aggregate principal amount of the Notes specified in this Indenture in
connection with such action, any holder of a Note which is shown by the
evidence to be included in the Notes the holders of which have consented to
such action may, by filing



                                     -54-
<PAGE>   59

written notice with the Trustee at its Corporate Trust Office and upon proof of
holding as provided in Section 9.2, revoke such action so far as concerns such
Note. Except as aforesaid, any such action taken by the holder of any Note
shall be conclusive and binding upon such holder and upon all future holders
and owners of such Note and of any Notes issued in exchange or substitution
therefor, irrespective of whether any notation in regard thereto is made upon
such Note or any Note issued in exchange or substitution therefor.

                                   ARTICLE X

         of the Notes under any other provision of this Indenture or under
         applicable law; or

                  (5)    to take any other action authorized by this Indenture

<PAGE>   60

notices shall be mailed not less than twenty (20) nor more than ninety (90)
days prior to the date fixed for the meeting.

         Any meeting of Noteholders shall be valid without notice if the
holders of all Notes then outstanding are present in person or by proxy or if

outstanding, and if the Company and the Trustee are either present by duly
authorized representatives or have, before or after the meeting, waived notice.

         Section 10.3    Call of Meetings by Company or Noteholders. In case at
any time the Company, pursuant to a resolution of its Board of Directors, or
the holders of at least 10% in aggregate principal amount of the Notes then

by written request setting forth in reasonable detail the action proposed to be
taken at the meeting, and the Trustee shall not have mailed the notice of such

         Section 10.4    Qualifications for Voting. To be entitled to vote at
any meeting of Noteholders a person shall (a) be a holder of one or more Notes
on the record date pertaining to such meeting or (b) be a person appointed by

persons who shall be entitled to be present or to speak at any meeting of
Noteholders shall be the persons entitled to vote at such meeting and their
counsel and any representatives of the Trustee and its counsel and any
representatives of the Company and its counsel.

         Section 10.5    Regulations. Notwithstanding any other provisions of 
this Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Noteholders, in regard to proof of the holding of
Notes and of the appointment of proxies, and in regard to the appointment and
duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters
concerning the conduct of the meeting as it shall think fit.

         The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Noteholders as provided in Section 10.3, in which case the
Company or the Noteholders calling the meeting, as the case may be, shall in
like manner appoint a temporary chairman. A permanent chairman and a permanent
secretary of the meeting shall be elected by vote of the holders of a majority

         Subject to the provisions of Section 9.4, at any meeting each
Noteholder or proxyholder shall be entitled to one vote for each $1,000
principal amount of Notes held or represented by him; provided, however, that
no vote shall be cast or counted at any meeting in respect of any

be not outstanding. The chairman of the meeting shall have no right to vote
other than by virtue of Notes held by him or instruments in writing as

of Section 10.2 or 10.3 may be adjourned from time to time by the holders of a
majority of the aggregate principal amount of Notes represented at the meeting,
whether or not constituting a quorum, and the meeting may be held as so

chairman of the meeting shall appoint two inspectors of votes who shall count
all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports in
duplicate of all votes cast at the meeting. A record in duplicate of the
proceedings of each meeting of Noteholders shall be prepared by the secretary
of the meeting and there shall be attached to said record the original reports
of the inspectors of votes on any vote by ballot taken thereat and affidavits
by one or more persons having knowledge of the facts setting forth a copy of
the notice of the meeting and showing that said notice was mailed as provided
in Section 10.2. The record shall show the principal amount of the Notes voting

by the affidavits of the permanent chairman and secretary of the meeting and
one of the duplicates shall be delivered to the Company and the other to the
Trustee to be preserved by the Trustee, the latter to have attached thereto the
ballots voted at the meeting.

         Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

         Section 10.7    No Delay of Rights by Meeting. Nothing in this Article
X contained shall be deemed or construed to authorize or permit, by reason of
any call of a meeting of Noteholders or any rights expressly or impliedly
conferred hereunder to make such call, any hindrance or delay in the exercise
of any right or rights conferred upon or reserved to the Trustee or to the
Noteholders under any of the provisions of this Indenture or of the Notes.

                  (c)    to evidence the succession of another corporation to

                  (d)    to add to the covenants of the Company such further
         covenants, restrictions or conditions for the benefit of the holders

         Indenture as herein set forth; provided, however, that in respect of
         any such additional covenant, restriction or condition such
         supplemental indenture may provide for a particular period of grace
         after default (which period may be shorter or longer than that allowed

         changes for such purpose;

                  (f)    to cure any ambiguity or to correct or supplement any
         provision contained herein or in any supplemental indenture which may
         be defective or inconsistent with any other provision contained herein
         or in any supplemental indenture, or to make such other provisions in
         regard to matters or questions arising under this Indenture which
         shall not materially adversely affect the interests of the holders of
         the Notes;

         successor Trustee with respect to the Notes; or

         Indenture to such extent as shall be necessary to effect the
         qualifications of this Indenture under the Trust Indenture Act, or
         under any similar federal statute hereafter enacted.

          The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, to make any further appropriate
agreements and stipulations which may be therein contained and to accept the
conveyance, transfer and assignment of any property thereunder, but the Trustee
shall not be obligated to, but may in its discretion, enter into any
supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

         Any supplemental indenture authorized by the provisions of this
Section 11.1 may be executed by the Company and the Trustee without the consent
of the holders of any of the Notes at the time outstanding, notwithstanding any
of the provisions of Section 11.2.

         Section 11.2    Supplemental Indentures With Consent of Noteholders.
With the consent (evidenced as provided in Article IX) of the holders of not
less than a majority in aggregate principal amount of the Notes at the time
outstanding (determined in accordance with Section 9.4), the Company, when
authorized by the resolutions of the Board of Directors, and the Trustee may
from time to time and at any time enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or any
supplemental indenture or of modifying in any manner the rights of the holders
of the Notes; provided, however, that no such supplemental indenture shall (i)
extend the fixed maturity of any Note, or reduce the rate or extend the time of
payment of interest thereon, or reduce the principal amount thereof or premium,
if any, thereon, or reduce any amount payable on redemption or repurchase
thereof, impair, or change in any respect adverse to the holder of Notes, the
obligation of the Company to repurchase any Note at the option of the holder
upon the happening of a Repurchase Event, or impair or adversely affect the
right of any Noteholder to institute suit for the payment thereof, or change
the currency in which the Notes are payable, or impair or change in any respect
adverse to the Noteholders the right to convert the Notes into Common Stock
subject to the terms set forth herein, including Section 15.6, or modify the
provisions of this Indenture with respect to the subordination of the Notes in
a manner adverse to the Noteholders, without the consent of the holder of each
Note so affected, or (ii) reduce the aforesaid percentage of Notes, the holders
of which are required to consent to any such supplemental indenture, without
the consent of the holders of all Notes then outstanding.

         Upon the request of the Company, accompanied by a copy of the
resolutions of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of Noteholders as
aforesaid, the Trustee shall join with the Company in the execution of such



                                     -59-
<PAGE>   64

supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in is discretion, but shall not be obligated to, enter
into such supplemental indenture.

         It shall not be necessary for the consent of the Noteholders under
this Section 11.2 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

         Section 11.3    Effect of Supplemental Indentures. Any supplemental
indenture executed pursuant to the provisions of this Article XI shall comply
with the Trust Indenture Act, as then in effect. Upon the execution of any
supplemental indenture pursuant to the provisions of this Article XI, this
Indenture shall be and be deemed to be modified and amended in accordance
therewith and the respective rights, limitation of rights, obligations, duties
and immunities under this Indenture of the Trustee, the Company and the holders
of Notes shall thereafter be determined, exercised and enforced hereunder
subject in all respects to such modifications and amendments and all the terms
and conditions of any such supplemental indenture shall be and be deemed to be
part of the terms and conditions of this Indenture for any and all purposes.

         Section 11.4    Notation on Notes. Notes authenticated and delivered
after the execution of any supplemental indenture pursuant to the provisions of
this Article XI may bear a notation in form approved by the Trustee as to any
matter provided for in such supplemental indenture. If the Company or the
Trustee shall so determine, new Notes so modified as to conform, in the opinion
of the Trustee and the Board of Directors, to any modification of this
Indenture contained in any such supplemental indenture may, at the Company's
expense, be prepared and executed by the Company, authenticated by the Trustee
(or an authenticating agent duly appointed by the Trustee pursuant to Section
17.11) and delivered in exchange for the Notes then outstanding, upon surrender
of such Notes then outstanding.

         Section 11.5    Evidence of Compliance of Supplemental Indenture to Be

8.2, may receive an Officers' Certificate and an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant hereto
complies with the requirements of this Article XI.

Company shall not, directly or indirectly, consolidate with or merge with or
into any other Person or sell, lease, convey or transfer all its properties and
assets substantially as an entirety, whether in a single transaction or a
series of related transactions, to any Person or group of affiliated Persons
unless:

<PAGE>   65

                  (a)    either (i) in the case of a merger or consolidation
that does not involve a transfer of all or substantially all of the Company's
properties and assets, the Company is the surviving entity or (ii) in case the
Company shall consolidate with or merge into another Person or sell, lease,
convey or transfer all its properties and assets substantially as an entirety,
whether in a single transaction or a series of related transactions, to any
Person, the Person formed by such consolidation or into which the Company is
merged, or the Person which acquires by sale, conveyance or transfer, or which
leases the properties and assets of the Company substantially as an entirety,
shall be a corporation, limited liability company, partnership or trust, shall
be organized and validly existing under the laws of the United States of
America, any state thereof or the District of Columbia and shall expressly
assume, by an indenture supplemental hereto, executed and delivered to the
Trustee, in form satisfactory to the Trustee, the due and punctual payment of
the principal of, premium, if any, and interest (including Liquidated Damages,
if any) on all of the Notes as applicable, and the performance or observance of
every covenant of this Indenture on the part of the Company to be performed or
observed and shall have provided for the applicable conversion rights set forth
in Section 15.6 and the repurchase rights set forth in Article XVI;

                  (b)    immediately after giving effect to such transaction,
no Event of Default, and no event that after notice or lapse of time or both,
would become an Event of Default, shall have happened and be continuing; and

                  (c)    the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger, conveyance, transfer or lease and, if a supplemental indenture is
required in connection with such transaction, such supplemental indenture
comply with this Article and that all conditions precedent herein provided for
relating to such transaction have been complied with, together with any
documents required under Article IX.

         Section 12.2    Successor Corporation to Be Substituted. In case of 
any such consolidation, merger, sale, conveyance or lease in accordance with
Section 12.1, and, where required in accordance with Section 12.1(a) upon the
assumption by the successor corporation, by supplemental indenture, executed
and delivered to the Trustee and satisfactory in form to the Trustee, of the
due and punctual payment of the principal of and premium, if any, and interest
on all of the Notes and the due and punctual performance of all of the
covenants and conditions of this Indenture to be performed by the Company, such
successor corporation shall succeed to and be substituted for the Company, with
the same effect as if it had been named herein as the party of the first part.
Such successor corporation thereupon may cause to be signed, and may issue
either in its own name or in the name of SportsLine USA, Inc. any or all of the
Notes issuable hereunder which theretofore shall not have been signed by the
Company and delivered to the Trustee; and, upon the order of such successor
corporation instead of the Company and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall



                                     -61-
<PAGE>   66

authenticate and shall deliver, or cause to be authenticated and delivered, any
Notes which previously shall have been signed and delivered by the officers of
the Company to the Trustee for authentication, and any Notes which such
successor corporation thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All the Notes so issued shall in all respects have
the same legal rank and benefit under this Indenture as the Notes theretofore
or thereafter issued in accordance with the terms of this Indenture as though
all of such Notes had been issued at the date of the execution hereof. In the
event of any such consolidation, merger, sale, conveyance or lease, the person
named as the "Company" in the first paragraph of this Indenture or any
successor which shall thereafter have become such in the manner prescribed in
this Article XII may be dissolved, wound up and liquidated at any time
thereafter and such person shall be released from its liabilities as obligor
and maker of the Notes and from its obligations under this Indenture.

         In case of any such consolidation, merger, sale, conveyance or lease,
such changes in phraseology and form (but not in substance) may be made in the
Notes thereafter to be issued as may be appropriate.

         Section 12.3    Opinion of Counsel to Be Given Trustee. The Trustee,
subject to Sections 8.1 and 8.2, shall receive an Officers' Certificate and an
Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance or lease and any such assumption complies with the provisions
of this Article XII.

                                  ARTICLE XIII

                    SATISFACTION AND DISCHARGE OF INDENTURE

         Section 13.1    Discharge of Indenture. When (a) the Company shall 
deliver to the Trustee for cancellation all Notes theretofore authenticated
(other than any Notes which have been destroyed, lost or stolen and in lieu of
or in substitution for which other Notes shall have been authenticated and
delivered) and not theretofore canceled, or (b) all the Notes not theretofore
canceled or delivered to the Trustee for cancellation shall have become due and
payable, or are by their terms to become due and payable within one year or are
to be called for redemption within one year under arrangements satisfactory to
the Trustee for the giving of notice of redemption, and the Company shall
deposit with the Trustee, in trust, funds sufficient to pay at maturity or upon
redemption of all of the Notes (other than any Notes which shall have been
mutilated, destroyed, lost or stolen and in lieu of or in substitution for
which other Notes shall have been authenticated and delivered) not theretofore
canceled or delivered to the Trustee for cancellation, including principal and
premium, if any, and interest due or to become due to such date of maturity or
redemption date, as the case may be, and if in either case the Company shall
also pay or cause to be paid all other sums payable hereunder by the Company,
then this Indenture shall cease to be of further effect (except as to (i)
remaining rights of registration of 



                                     -62-
<PAGE>   67

transfer, substitution and exchange and conversion of Notes, (ii) rights
hereunder of Noteholders to receive payments of principal of and premium, if
any, and interest on, the Notes and the other rights, duties and obligations of
Noteholders, as beneficiaries hereof with respect to the amounts, if any, so
deposited with the Trustee and (iii) the rights, obligations and immunities of
the Trustee hereunder), and the Trustee, on demand of the Company accompanied
by an Officers' Certificate and an Opinion of Counsel as required by Section
17.5 and at the cost and expense of the Company, shall execute proper
instruments acknowledging satisfaction of and discharging this Indenture; the
Company, however, hereby agreeing to reimburse the Trustee for any costs or
expenses thereafter reasonably and properly incurred by the Trustee and to
compensate the Trustee for any services thereafter reasonably and properly
rendered by the Trustee in connection with this Indenture or the Notes.

         Section 13.2    Deposited Monies to Be Held in Trust by Trustee. 
Subject to Section 13.4, all monies deposited with the Trustee pursuant to
Section 13.1 shall be held in trust and applied by it to the payment,
notwithstanding the provisions of Article IV, either directly or through any
paying agent (including the Company if acting as its own paying agent), to the
holders of the particular Notes for the payment or redemption of which such
monies have been deposited with the Trustee, of all sums due and to become due
thereon for principal and interest and premium, if any.

         Section 13.3    Paying Agent to Repay Monies Held. Upon the 
satisfaction and discharge of this Indenture, all monies then held by any
paying agent of the Notes (other than the Trustee) shall, upon demand of the
Company, be repaid to it or paid to the Trustee, and thereupon such paying
agent shall be released from all further liability with respect to such monies.

         Section 13.4    Return of Unclaimed Monies. Subject to the 
requirements of applicable law, any monies deposited with or paid to the
Trustee for payment of the principal of, premium, if any, or interest on Notes
and not applied but remaining unclaimed by the holders of Notes for two years
after the date upon which the principal of, premium, if any, or interest on
such Notes, as the case may be, shall have become due and payable, shall be
repaid to the Company by the Trustee on demand and all liability of the Trustee
shall thereupon cease with respect to such monies; and the holder of any of the
Notes shall thereafter look only to the Company for any payment which such
holder may be entitled to collect unless an applicable abandoned property law
designates another person.

         Section 13.5    Reinstatement. If (i) the Trustee or the paying agent
is unable to apply any money in accordance with Section 13.2 by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application and (ii) the holders of at least a
majority in principal amount of the then outstanding Notes so request by
written notice to the Trustee, the Company's obligations under this Indenture
and the Notes shall be revived and reinstated as though no deposit had occurred
pursuant to Section 13.1 until such time as the Trustee or the paying agent is
permitted to apply all such money in accordance 



                                     -63-
<PAGE>   68

with Section 13.2; provided, however, that if the Company makes any payment of
interest on or principal of any Note following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the holders of
such Notes to receive such payment from the money held by the Trustee or paying
agent.

                    IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                             OFFICERS AND DIRECTORS

         Section 14.1    Indenture and Notes Solely Corporate Obligations. No
recourse for the payment of the principal of or premium, if any, or interest on
any Note, or for any claim based thereon or otherwise in respect thereof, and
no recourse under or upon any obligation, covenant or agreement of the Company
in this Indenture or in any supplemental indenture or in any Note, or because
of the creation of any indebtedness represented thereby, shall be had against
any incorporator, stockholder, employee, agent, officer or director or
subsidiary, as such, past, present or future, of the Company or of any
successor corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being
expressly understood that all such liability is hereby expressly waived and
released as a condition of, and as a consideration for, the execution of this
Indenture and the issue of the Notes.

                                   ARTICLE XV

                              CONVERSION OF NOTES

         Section 15.1    Right to Convert. Subject to and upon compliance with
the provisions of this Indenture, the holder of any Note shall have the right,
at his option, at any time following the date of original issuance of the Notes
and prior to the close of business on April 1, 2006 (except that, with respect
to any Note or portion of a Note which shall be called for redemption, such
right shall terminate, except as provided in the fifth paragraph of Section
15.2 and Section 3.4, at the close of business on the Business Day next
preceding the date fixed for redemption of such Note or portion of a Note
unless the Company shall default in payment due upon redemption thereof) to
convert the principal amount of any such Note, or any portion of such principal
amount which is $1,000 or an integral multiple thereof, into that number of
fully paid and non-assessable shares of Common Stock (as such shares shall then
be constituted) obtained by dividing the principal amount of the Note or
portion thereof surrendered for conversion by the Conversion Price in effect at
such time, by surrender of the Note so to be converted in whole or in part in
the manner provided in Section 15.2. A holder of Notes is not entitled to any
rights of a holder of Common Stock until such holder has converted his Notes to
Common Stock, and only to the extent such Notes are deemed to have been
converted to Common Stock under this Article XV. A Note with respect to which a
holder has delivered a notice in accordance with Section 16.2 regarding such
holder's election to require the Company to repurchase such holder's Notes
following the occurrence of a Repurchase Event may be converted in accordance
with this Article XV only if such holder withdraws such notice by delivering a
written notice of withdrawal to the Company prior to the close of business on
last Business Day prior to the day fixed for repurchase.

         Section 15.2    Exercise of Conversion Privilege; Issuance of Common 
Stock on Conversion; No Adjustment for Interest or Dividends. In order to
exercise the conversion privilege with respect to any Note in definitive form,
the holder of any such Note to be converted in whole or in part shall surrender
such Note, duly endorsed, at an office or agency maintained by the Company
pursuant to Section 5.2, accompanied by the funds, if any, required by the
penultimate paragraph of this Section 15.2, and shall give written notice of
conversion in the form provided on the Notes (or such other notice which is
acceptable to the Company) to the office or agency that the holder elects to
convert such Note or such portion thereof specified in said notice. Such notice
shall also state the name or names (with address) in which the certificate or
certificates for shares of Common Stock which shall be issuable on such
conversion shall be issued, and shall be accompanied by transfer taxes, if
required pursuant to Section 15.7. Each such Note surrendered for conversion
shall, unless the shares issuable on conversion are to be issued in the same
name as the registration of such Note, be duly endorsed by, or be accompanied
by instruments of transfer in form satisfactory to the Company duly executed
by, the holder or his duly authorized attorney.

         In order to exercise the conversion privilege with respect to any
interest in the Global Note, the beneficial holder must complete the
appropriate instruction form for conversion pursuant to the Depositary's
book-entry conversion program, deliver by book-entry delivery an interest in
the Global Note, furnish appropriate endorsements and transfer documents if
required by the Company or the Trustee or conversion agent, and pay the funds,
if any, required by the penultimate paragraph of this Section 15.2 and any
transfer taxes, if required pursuant to Section 15.7.

         As promptly as practicable after satisfaction of the requirements for
conversion set forth above (but in no event later than three (3) Business Days
after satisfaction of such requirements for conversion), subject to compliance
with any restrictions on transfer if shares issuable on conversion are to be
issued in a name other than that of the Noteholder (as if such transfer were a
transfer of the Note or Notes (or portion thereof) so converted), the Company
shall issue and shall deliver to such holder at the office or agency maintained
by the Company for such purpose pursuant to Section 5.2, a certificate or
certificates for the number of full shares of Common Stock issuable upon the
conversion of such Note or portion thereof in accordance with the provisions of
this Article and a check or cash in respect of any fractional interest in
respect of a share of Common Stock arising upon such conversion, as provided in
Section 15.3 (which payment, if any, shall be paid no later than three (3)
Business Days after satisfaction of the requirements for conversion set forth
above). In case any Note of a denomination greater than $1,000 shall be
surrendered for partial conversion, and subject to Section 2.3, the Company
shall execute and the Trustee shall authenticate and deliver to the holder of
the Note so surrendered, without charge to him, a new Note or Notes in
authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Note.



                                     -66-
<PAGE>   71

         Each conversion shall be deemed to have been effected as to any such
Note (or portion thereof) on the date on which the requirements set forth above
in this Section 15.2 have been satisfied as to such Note (or portion thereof),
and the person in whose name any certificate or certificates for shares of
Common Stock shall be issuable upon such conversion shall be deemed to have
become on said date the holder of record of the shares represented thereby;
provided, however, that any such surrender on any date when the stock transfer
books of the Company shall be closed shall constitute the person in whose name
the certificates are to be issued as the record holder thereof for all purposes
on the next succeeding day on which such stock transfer books are open, but
such conversion shall be at the Conversion Price in effect on the date upon
which such Note shall be surrendered.

         Any Note or portion thereof surrendered for conversion during the
period beginning after the close of business on the record date for any
interest payment date through the close of business on the Business Day next
preceding such interest payment date shall (unless such Note or portion thereof
being converted shall have been called for redemption pursuant to a redemption
notice mailed to the Noteholders in accordance with Section 3.2) be accompanied
by payment, in New York Clearing House funds or other funds acceptable to the
Company, of an amount equal to the interest otherwise payable on such interest
payment date on the principal amount being converted; provided, however, that
no such payment need be made if there shall exist at the time of conversion a
default in the payment of interest on the Notes. Except as provided above in
this Section 15.2, no adjustment shall be made for interest accrued on any Note
converted or for dividends on any shares issued upon the conversion of such
Note as provided in this Article.

         Upon the conversion of an interest in the Global Note, the Trustee, or
the Custodian at the direction of the Trustee, shall make a notation on the
Global Note as to the reduction in the principal amount represented thereby.

         Section 15.3    Cash Payments in Lieu of Fractional Shares. No 
fractional shares of Common Stock or scrip representing fractional shares shall
be issued upon conversion of Notes. If more than one Note shall be surrendered
for conversion at one time by the same holder, the number of full shares which
shall be issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Notes (or specified portions thereof to the
extent permitted hereby) so surrendered for conversion. If any fractional share
of stock otherwise would be issuable upon the conversion of any Note or Notes,
the Company shall calculate and pay a cash adjustment in lieu of such
fractional share at the current market value thereof to the holder of Notes.
The current market value of a share of Common Stock shall be the Closing Price
on the first Trading Day immediately preceding the day on which the Notes (or
specified portions thereof) are deemed to have been converted and such Closing
Price shall be determined as provided in Section 15.5(h).

         Section 15.4    Conversion Price. The conversion price shall be as
specified in the form of Note (herein called the "Conversion Price") attached
as Exhibit A hereto, subject to adjustment as provided in this Article XV.

         Section 15.5    Adjustment of Conversion Price. The Conversion Price 
shall be adjusted from time to time by the Company as follows:

                  (a)    In case the Company shall hereafter pay a dividend or
         make a distribution to all holders of the outstanding Common Stock in
         shares of Common Stock, the Conversion Price in effect at the opening
         of business on the date following the date fixed for the determination
         of stockholders entitled to receive such dividend or other
         distribution shall be reduced by multiplying such Conversion Price by
         a fraction of which the numerator shall be the number of shares of
         Common Stock outstanding at the close of business on the Record Date
         (as defined in Section 15.5(h)) fixed for such determination and the
         denominator shall be the sum of such number of shares and the total
         number of shares constituting such dividend or other distribution,
         such reduction to become effective immediately after the opening of
         business on the day following the Record Date. If any dividend or
         distribution of the type described in this Section 15.5(a) is declared
         but not so paid or made, the Conversion Price shall again be adjusted
         to the Conversion Price which would then be in effect if such dividend
         or distribution had not been declared.

                  (b)    In case the Company shall issue rights or warrants to
         all holders of its outstanding shares of Common Stock entitling them
         (for a period expiring within forty-five (45) days after the date
         fixed for the determination of stockholders entitled to receive such
         rights or warrants) to subscribe for or purchase shares of Common
         Stock at a price per share less than the Current Market Price (as
         defined in Section 15.5(h)) on the Record Date fixed for the
         determination of stockholders entitled to receive such rights or
         warrants, the Conversion Price shall be adjusted so that the same
         shall equal the price determined by multiplying the Conversion Price
         in effect at the opening of business on the date after such Record
         Date by a fraction of which the numerator shall be the number of
         shares of Common Stock outstanding at the close of business on the
         Record Date plus the number of shares which the aggregate offering
         price of the total number of shares so offered for subscription or
         purchase would purchase at such Current Market Price, and of which the
         denominator shall be the number of shares of Common Stock outstanding
         on the close of business on the Record Date plus the total number of
         additional shares of Common Stock so offered for subscription or
         purchase. Such adjustment shall become effective immediately after the
         opening of business on the day following the Record Date fixed for
         determination of stockholders entitled to receive such rights or
         warrants. To the extent that shares of Common Stock are not delivered
         pursuant to such rights or warrants, upon the expiration or
         termination of such rights or warrants the Conversion Price shall be
         readjusted to the Conversion Price which would then be in effect had
         the adjustments



                                     -68-
<PAGE>   73

         made upon the issuance of such rights or warrants been made on the
         basis of delivery of only the number of shares of Common Stock
         actually delivered. In the event that such rights or warrants are not
         so issued, the Conversion Price shall again be adjusted to be the
         Conversion Price which would then be in effect if such date fixed for
         the determination of stockholders entitled to receive such rights or
         warrants had not been fixed. In determining whether any rights or
         warrants entitle the holders to subscribe for or purchase shares of
         Common Stock at less than such Current Market Price, and in
         determining the aggregate offering price of such shares of Common
         Stock, there shall be taken into account any consideration received
         for such rights or warrants, the value of such consideration, if other
         than cash, to be determined by the Board of Directors.

                  (c)    In case the outstanding shares of Common Stock shall
         be subdivided into a greater number of shares of Common Stock, the
         Conversion Price in effect at the opening of business on the day
         following the day upon which such subdivision becomes effective shall
         be proportionately reduced, and conversely, in case outstanding shares
         of Common Stock shall be combined into a smaller number of shares of
         Common Stock, the Conversion Price in effect at the opening of
         business on the day following the day upon which such combination
         becomes effective shall be proportionately increased, such reduction
         or increase, as the case may be, to become effective immediately after
         the opening of business on the day following the day upon which such
         subdivision or combination becomes effective.

                  (d)    In case the Company shall, by dividend or otherwise,
         distribute to all holders of its Common Stock shares of any class of
         capital stock of the Company (other than any dividends or
         distributions to which Section 15.5(a) applies) or evidences of its
         indebtedness, cash or other assets (including securities, but
         excluding (1) any rights or warrants referred to in Section 15.5(b)
         and, (2) dividends and distributions (A) in connection with the
         liquidation, dissolution or winding up of the Company or paid (B)
         exclusively in cash and (3) any capital stock, evidences of
         indebtedness, cash or assets distributed upon a merger or
         consolidation to which Section 15.6 applies) (the foregoing
         hereinafter in this Section 15.5(d) called the "Securities")), unless
         the Company elects to reserve such Securities for distribution to the
         Noteholders upon conversion of the Notes so that any such holder
         converting Notes will receive upon such conversion, in addition to the
         shares of Common Stock to which such holder is entitled, the amount
         and kind of such Securities which such holder would have received if
         such holder had converted its Notes into Common Stock immediately
         prior to the Record Date (as defined in Section 15.5(h) for such
         distribution of the Securities) then, in each such case, the
         Conversion Price shall be reduced so that the same shall be equal to
         the price determined by multiplying the Conversion Price in effect
         immediately prior to the close of business on the Record Date (as
         defined in Section 15.5(h)) with respect to such distribution by a
         fraction of which the numerator shall be the Current Market Price
         (determined as provided in Section 15.5(h)) on such date less the fair
         market value (as determined by the



                                     -69-
<PAGE>   74

         Board of Directors, whose determination shall be conclusive and
         described in a Board Resolution) on such date of the portion of the
         Securities so distributed applicable to one share of Common Stock and
         the denominator shall be such Current Market Price, such reduction to
         become effective immediately prior to the opening of business on the
         day following the Record Date; provided, however, that in the event
         the then fair market value (as so determined) of the portion of the
         Securities so distributed applicable to one share of Common Stock is
         equal to or greater than the Current Market Price on the Record Date,
         in lieu of the foregoing adjustment, adequate provision shall be made
         so that each Noteholder shall have the right to receive upon
         conversion of a Note (or any portion thereof) the amount of Securities
         such holder would have received had such holder converted such Note
         (or portion thereof) immediately prior to such Record Date. In the
         event that such dividend or distribution is not so paid or made, the
         Conversion Price shall again be adjusted to be the Conversion Price
         which would then be in effect if such dividend or distribution had not
         been declared. If the Board of Directors determines the fair market
         value of any distribution for purposes of this Section 15.5(d) by
         reference to the actual or when issued trading market for any
         securities comprising all or part of such distribution, it must in
         doing so consider the prices in such market over the same period (the
         "Reference Period") used in computing the Current Market Price
         pursuant to Section 15.5(h) to the extent possible, unless the Board
         of Directors in a board resolution determines in good faith that
         determining the fair market value during the Reference Period would
         not be in the best interest of the Noteholder.

                  In the event that the Company implements a stockholder rights
         plan, such rights plan shall provide that upon conversion of the Notes
         the holders will receive, in addition to the Common Stock issuable
         upon such conversion, the rights issued under such rights plan
         (notwithstanding the occurrence of an event causing such rights to
         separate from the Common Stock at or prior to the time of conversion).
         Any distribution of rights or warrants pursuant to a stockholder
         rights plan complying with the requirements set forth in the
         immediately preceding sentence of this paragraph shall not constitute
         a distribution of rights or warrants for the purposes of this Section
         15.5(d).

                  Rights or warrants distributed by the Company to all holders
         of Common Stock entitling the holders thereof to subscribe for or
         purchase shares of the Company's capital stock (either initially or
         under certain circumstances), which rights or warrants, until the
         occurrence of a specified event or events ("Trigger Event"): (i) are
         deemed to be transferred with such shares of Common Stock; (ii) are
         not exercisable; and (iii) are also issued in respect of future
         issuances of Common Stock, shall be deemed not to have been
         distributed for purposes of this Section 15.5(d) (and no adjustment to
         the Conversion Price under this Section 15.5(d) will be required)
         until the occurrence of the earliest Trigger Event. If such right or
         warrant is subject to subsequent events, upon the occurrence of which
         such right or warrant shall become exercisable to purchase different
         securities, evidences of indebtedness or other assets or entitle the
         holder to purchase a



                                     -70-

         different number or amount of the foregoing or to purchase any of the
         foregoing at a different purchase price, then the occurrence of each
         such event shall be deemed to be the date of issuance and record date
         with respect to a new right or warrant (and a termination or
         expiration of the existing right or warrant without exercise by the
         holder thereof). In addition, in the event of any distribution (or
         deemed distribution) of rights or warrants, or any Trigger Event or
         other event (of the type described in the preceding sentence) with
         respect thereto, that resulted in an adjustment to the Conversion
         Price under this Section 15.5(d), (1) in the case of any such rights
         or warrants which shall all have been redeemed or repurchased without
         exercise by any holders thereof, the Conversion Price shall be
         readjusted upon such final redemption or repurchase to give effect to
         such distribution or Trigger Event, as the case may be, as though it
         were a cash distribution, equal to the per share redemption or
         repurchase price received by a holder of Common Stock with respect to
         such rights or warrants (assuming such holder had retained such rights
         or warrants), made to all holders of Common Stock as of the date of
         such redemption or repurchase, and (2) in the case of such rights or
         warrants all of which shall have expired or been terminated without
         exercise, the Conversion Price shall be readjusted as if such rights
         and warrants had never been issued.

                  For purposes of this Section 15.5(d) and Sections 15.5(a) and
         (b), any dividend or distribution to which this Section 15.5(d) is
         applicable that also includes shares of Common Stock, or rights or
         warrants to subscribe for or purchase shares of Common Stock to which
         Section 15.5(b) applies (or both), shall be deemed instead to be (1) a
         dividend or distribution of the evidences of indebtedness, assets,
         shares of capital stock, rights or warrants other than such shares of
         Common Stock or rights or warrants to which Section 15.5(b) applies
         (and any Conversion Price reduction required by this Section 15.5(d)
         with respect to such dividend or distribution shall then be made)
         immediately followed by (2) a dividend or distribution of such shares
         of Common Stock or such rights or warrants (and any further Conversion
         Price reduction required by Sections 15.5(a) and (b) with respect to
         such dividend or distribution shall then be made, except (A) the
         Record Date of such dividend or distribution shall be substituted as
         "the date fixed for the determination of stockholders entitled to
         receive such dividend or other distribution", "Record Date fixed for
         such determination" and "Record Date" within the meaning of Section
         15.5(a) and as "the date fixed for the determination of stockholders
         entitled to receive such rights or warrants", "the Record Date fixed
         for the determination of the stockholders entitled to receive such
         rights or warrants" and "such Record Date" within the meaning of
         Section 15.5(b) and (B) any shares of Common Stock included in such
         dividend or distribution shall not be deemed "outstanding at the close
         of business on the date fixed for such determination" within the
         meaning of Section 15.5(a).

                  (e)    In case the Company shall, by dividend or otherwise,
         distribute to all holders of its Common Stock cash (excluding any cash
         that is distributed upon a merger or consolidation to which Section
         15.6 applies or as part of a distribution referred to in



                                     -71-

         Section 15.5(d)), in an aggregate amount that, combined together with
         (1) the aggregate amount of any other such distributions to all
         holders of its Common Stock made exclusively in cash within the twelve
         (12) months preceding the date of payment of such distribution, and in
         respect of which no adjustment pursuant to this Section 15.5(e) has
         been made, and (2) the aggregate of any cash plus the fair market
         value (as determined by the Board of Directors, whose determination
         shall be conclusive and described in a Board Resolution) of
         consideration payable in respect of any tender offer by the Company or
         any of its subsidiaries for all or any portion of the Common Stock
         concluded within the twelve (12) months preceding the date of payment
         of such distribution, and in respect of which no adjustment pursuant
         to Section 15.5(f) has been made, exceeds 10% of the product of the
         Current Market Price (determined as provided in Section 15.5(h)) on
         the Record Date with respect to such distribution times the number of
         shares of Common Stock outstanding on such date, then, and in each
         such case, immediately after the close of business on such date, the
         Conversion Price shall be reduced so that the same shall equal the
         price determined by multiplying the Conversion Price in effect
         immediately prior to the close of business on such Record Date by a
         fraction (i) the numerator of which shall be equal to the Current
         Market Price on the Record Date less an amount equal to the quotient
         of (x) the excess of such combined amount over such 10% and (y) the
         number of shares of Common Stock outstanding on the Record Date and
         (ii) the denominator of which shall be equal to the Current Market
         Price on such date; provided, however, that in the event the portion
         of the cash so distributed applicable to one share of Common Stock is
         equal to or greater than the Current Market Price of the Common Stock
         on the Record Date, in lieu of the foregoing adjustment, adequate
         provision shall be made so that each Noteholder shall have the right
         to receive upon conversion of a Note (or any portion thereof) the
         amount of cash such holder would have received had such holder
         converted such Note (or portion thereof) immediately prior to such
         Record Date. In the event that such dividend or distribution is not so
         paid or made, the Conversion Price shall again be adjusted to be the
         Conversion Price which would then be in effect if such dividend or
         distribution had not been declared. Any cash distribution to all
         holders of Common Stock as to which the Company makes the election
         permitted by Section 15.5(n) and as to which the Company has complied
         with the requirements of such Section shall be treated as not having
         been made for all purposes of this Section 15.5(e)).

                  (f)    In case a tender offer made by the Company or any
         Subsidiary for all or any portion of the Common Stock shall expire and
         such tender offer (as amended upon the expiration thereof) shall
         require the payment to stockholders (based on the acceptance (up to
         any maximum specified in the terms of the tender offer) of Purchased
         Shares (as defined below)) of an aggregate consideration having a fair
         market value (as determined by the Board of Directors, whose
         determination shall be conclusive and described in a Board Resolution)
         that combined together with (1) the aggregate of the cash plus the
         fair market value (as determined by the Board of Directors, whose
         determination shall be conclusive and described in a Board
         Resolution), as of the expiration of such tender offer,



                                     -72-

         of consideration payable in respect of any other tender offers, by the
         Company or any of its subsidiaries for all or any portion of the
         Common Stock expiring within the twelve (12) months preceding the
         expiration of such tender offer and in respect of which no adjustment
         pursuant to this Section 15.5(f) has been made and (2) the aggregate
         amount of any distributions to all holders of the Company's Common
         Stock made exclusively in cash within twelve (12) months preceding the
         expiration of such tender offer and in respect of which no adjustment
         pursuant to Section 15.5(e) has been made, exceeds 10% of the product
         of the Current Market Price (determined as provided in Section
         15.5(h)) as of the last time (the "Expiration Time") tenders could
         have been made pursuant to such tender offer (as it may be amended)
         times the number of shares of Common Stock outstanding (including any
         tendered shares) on the Expiration Time, then, and in each such case,
         immediately prior to the opening of business on the day after the date
         of the Expiration Time, the Conversion Price shall be adjusted so that
         the same shall equal the price determined by multiplying the
         Conversion Price in effect immediately prior to close of business on
         the date of the Expiration Time by a fraction of which the numerator
         shall be the number of shares of Common Stock outstanding (including
         any tendered shares) on the Expiration Time multiplied by the Current
         Market Price of the Common Stock on the Trading Day next succeeding
         the Expiration Time and the denominator shall be the sum of (x) the
         fair market value (determined as aforesaid) of the aggregate
         consideration payable to stockholders based on the acceptance (up to
         any maximum specified in the terms of the tender offer) of all shares
         validly tendered and not withdrawn as of the Expiration Time (the
         shares deemed so accepted, up to any such maximum, being referred to
         as the "Purchased Shares") and (y) the product of the number of shares
         of Common Stock outstanding (less any Purchased Shares) on the
         Expiration Time and the Current Market Price of the Common Stock on
         the Trading Day next succeeding the Expiration Time, such reduction
         (if any) to become effective immediately prior to the opening of
         business on the day following the Expiration Time. In the event that
         the Company is obligated to purchase shares pursuant to any such
         tender offer, but the Company is permanently prevented by applicable
         law from effecting any such purchases or all such purchases are
         rescinded, the Conversion Price shall again be adjusted to be the
         Conversion Price which would then be in effect if such tender offer
         had not been made. If the application of this Section 15.5(f) to any
         tender offer would result in an increase in the Conversion Price, no
         adjustment shall be made for such tender offer under this Section
         15.5(f). Any cash distribution to all holders of Common Stock as to
         which the Company has made the election permitted by Section 15.5(n)
         and as to which the Company has complied with the requirements of such
         Section shall be treated as not having been made for all purposes of
         this Section 15.5(f).

                  (g)    In case of a tender or exchange offer made by a person
         other than the Company or any Subsidiary for an amount which increases
         the offeror's ownership of Common Stock to more than 25% of the Common
         Stock outstanding and shall involve the payment by such person of
         consideration per share of Common Stock having a fair



                                     -73-

         market value (as determined by the Board of Directors), whose
         determination shall be conclusive, and described in a resolution of
         the Board of Directors at the last time (the "Expiration Time")
         tenders or exchanges may be made pursuant to such tender or exchange
         offer (as it shall have been amended) that exceeds the Current Market
         Price of the Common Stock on the Trading Day next succeeding the
         Expiration Time, and in which, as of the Expiration Time the Board of
         Directors is not recommending rejection of the offer, the Conversion
         Price shall be reduced so that the same shall equal the price
         determined by multiplying the Conversion Price in effect immediately
         prior to the Expiration Time by a fraction of which the numerator
         shall be the number of shares of Common Stock outstanding (including
         any tendered or exchanged shares) on the Expiration Time multiplied by
         the current Market Price of the Common Stock on the Trading Day next
         succeeding the Expiration Time and the denominator shall be the sum of
         (x) the fair market value (determined as aforesaid) of the aggregate
         consideration payable to stockholders based on the acceptance (up to
         any maximum specified in the terms of the tender or exchange offer) of
         all shares validly tendered or exchanged and not withdrawn as of the
         Expiration Time (the shares deemed so accepted, up to any such
         maximum, being referred to as the "Purchased Shares") and (y) the
         product of the number of shares of Common Stock outstanding (less any
         Purchased Shares) on the Expiration Time and the Current Market Price
         of the Common Stock on the Trading Day next succeeding the Expiration
         Time, such reduction to become effective immediately prior to the
         opening of business on the day following the Expiration Time. In the
         event that such person is obligated to purchase shares pursuant to any
         such tender or exchange offer, but such person is permanently
         prevented by applicable law from effecting any such purchases or all
         such purchases are rescinded, the Conversion Price shall again be
         adjusted to be the Conversion Price which would then be in effect if
         such tender or exchange offer had not been made. Notwithstanding the
         foregoing, the adjustment described in this Section 15.5(g) shall not
         be made if, as of the Expiration Time, the offering documents with
         respect to such offer disclose a plan or intention to cause the
         Company to engage in any transaction described in Article XII.

                  (h)    For purposes of this Section 15.5, the following terms
         shall have the meaning indicated:

                         (1)       "Closing Price" with respect to any
                  securities on any day shall mean the closing sale price
                  regular way on such day or, in case no such sale takes place
                  on such day, the average of the reported closing bid and
                  asked prices, regular way, in each case on the Nasdaq
                  National Market or New York Stock Exchange, as applicable,
                  or, if such security is not listed or admitted to trading on
                  such National Market or Exchange, on the principal national
                  security exchange or quotation system on which such security
                  is quoted or listed or admitted to trading, or, if not quoted
                  or listed or admitted to trading on any national securities
                  exchange or quotation system, the average of the closing bid
                  and asked prices of 



                                     -74-
<PAGE>   79

                  such security on the over-the-counter market on the day in
                  question as reported by the National Quotation Bureau
                  Incorporated, or a similar generally accepted reporting
                  service, or if not so available, in such manner as furnished
                  by any New York Stock Exchange member firm selected from time
                  to time by the Board of Directors for that purpose, or a
                  price determined in good faith by the Board of Directors,
                  whose determination shall be conclusive and described in a
                  Board Resolution.

                           (2)     "Current Market Price" shall mean the 
                  average of the daily Closing Prices per share of Common Stock
                  for the ten (10) consecutive Trading Days immediately prior
                  to the date in question; provided, however, that (1) if the
                  "ex" date (as hereinafter defined) for any event (other than
                  the issuance or distribution requiring such computation) that
                  requires an adjustment to the Conversion Price pursuant to
                  Section 15.5(a), (b), (c), (d), (e), (f) or (g) occurs during
                  such ten (10) consecutive Trading Days, the Closing Price for
                  each Trading Day prior to the "ex" date for such other event
                  shall be adjusted by multiplying such Closing Price by the
                  same fraction by which the Conversion Price is so required to
                  be adjusted as a result of such other event, (2) if the "ex"
                  date for any event (other than the issuance or distribution
                  requiring such computation) that requires an adjustment to
                  the Conversion Price pursuant to Section 15.5(a), (b), (c),
                  (d), (e), (f) or (g) occurs on or after the "ex" date for the
                  issuance or distribution requiring such computation and prior
                  to the day in question, the Closing Price for each Trading
                  Day on and after the "ex" date for such other event shall be
                  adjusted by multiplying such Closing Price by the reciprocal
                  of the fraction by which the Conversion Price is so required
                  to be adjusted as a result of such other event, and (3) if
                  the "ex" date for the issuance or distribution requiring such
                  computation is prior to the day in question, after taking
                  into account any adjustment required pursuant to clause (1)
                  or (2) of this proviso, the Closing Price for each Trading
                  Day on or after such "ex" date shall be adjusted by adding
                  thereto the amount of any cash and the fair market value (as
                  determined by the Board of Directors in a manner consistent
                  with any determination of such value for purposes of Section
                  15.5(d), (f) or (g), whose determination shall be conclusive
                  and described in a Board Resolution) of the evidences of
                  indebtedness, shares of capital stock or assets being
                  distributed applicable to one share of Common Stock as of the
                  close of business on the day before such "ex" date. For
                  purposes of any computation under Sections 15.5(f) or (g),
                  the Current Market Price of the Common Stock on any date
                  shall be deemed to be the average of the daily Closing Prices
                  per share of Common Stock for such day and the next two
                  succeeding Trading Days; provided, however, that if the "ex"
                  date for any event (other than the tender offer requiring
                  such computation) that requires an adjustment to the
                  Conversion Price pursuant to Section 15.5(a), (b), (c), (d),
                  (e), (f) and (g) occurs on or after the Expiration Time for
                  the tender or exchange offer requiring such computation and

                  prior to the day in question, the Closing Price for each
                  Trading Day on and after the "ex" date for such other event
                  shall be adjusted by multiplying such Closing Price by the
                  reciprocal of the fraction by which the Conversion Price is
                  so required to be adjusted as a result of such other event.
                  For purposes of this paragraph, the term "ex" date, (1) when
                  used with respect to any issuance or distribution, means the
                  first date on which the Common Stock trades regular way on
                  the relevant exchange or in the relevant market from which
                  the Closing Price was obtained without the right to receive
                  such issuance or distribution, (2) when used with respect to
                  any subdivision or combination of shares of Common Stock,
                  means the first date on which the Common Stock trades regular
                  way on such exchange or in such market after the time at
                  which such subdivision or combination becomes effective, and
                  (3) when used with respect to any tender or exchange offer
                  means the first date on which the Common Stock trades regular
                  way on such exchange or in such market after the Expiration
                  Time of such offer. Notwithstanding the foregoing, whenever
                  successive adjustments to the Conversion Price are called for
                  pursuant to this Section 15.5, such adjustments shall be made
                  to the Current Market Price as may be necessary or
                  appropriate to effectuate the intent of this Section 15.5 and
                  to avoid unjust or inequitable results as determined in good
                  faith by the Board of Directors.

                           (3)     "fair market value" shall mean the amount 
                  which a willing buyer would pay a willing seller in an arm's
                  length transaction.

                           (4)     "Record Date" shall mean, with respect to 
                  any dividend, distribution or other transaction or event in
                  which the holders of Common Stock have the right to receive
                  any cash, securities or other property or in which the Common
                  Stock (or other applicable security) is exchanged for or
                  converted into any combination of cash, securities or other
                  property, the date fixed for determination of stockholders
                  entitled to receive such cash, securities or other property
                  (whether such date is fixed by the Board of Directors or by
                  statute, contract or otherwise).

                           (5)     "Trading Day" shall mean (x) if the 
                  applicable security is listed or admitted for trading on the
                  New York Stock Exchange or another national security
                  exchange, a day on which the New York Stock Exchange or
                  another national security exchange is open for business or
                  (y) if the applicable security is quoted on the Nasdaq
                  National Market, a day on which trades may be made thereon or
                  (z) if the applicable security is not so listed, admitted for
                  trading or quoted, any day other than a Saturday or Sunday or
                  a day on which banking institutions in the State of New York
                  are authorized or obligated by law or executive order to
                  close.

                  (i)    The Company may make such reductions in the Conversion
         Price, in addition to those required by Sections 15.5(a), (b), (c),
         (d), (e), (f) and (g), as the Board of Directors considers to be
         advisable to avoid or diminish any income tax to holders of Common
         Stock or rights to purchase Common Stock resulting from any dividend
         or distribution of stock (or rights to acquire stock) or from any
         event treated as such for income tax purposes.

                  To the extent permitted by applicable law, the Company from
         time to time may reduce the Conversion Price by any amount for any
         period of time if the period is at least twenty (20) days, the
         reduction is irrevocable during the period and the Board of Directors
         shall have made a determination that such reduction would be in the
         best interests of the Company, which determination shall be conclusive
         and described in a Board Resolution. Whenever the Conversion Price is
         reduced pursuant to the preceding sentence, the Company shall mail to
         the holder of each Note at his last address appearing on the Note
         register provided for in Section 2.5 a notice of the reduction at
         least fifteen (15) days prior to the date the reduced Conversion Price
         takes effect, and such notice shall state the reduced Conversion Price
         and the period during which it will be in effect.

                  (j)    No adjustment in the Conversion Price shall be 
         required unless such adjustment would require an increase or decrease
         of at least 1% in such price; provided, however, that any adjustments
         which by reason of this Section 15.5(j) are not required to be made
         shall be carried forward and taken into account in any subsequent
         adjustment. All calculations under this Article XV shall be made by
         the Company and shall be made to the nearest 1/1,000th of a cent or to
         the nearest 1/10,000th of a share, as the case may be. No adjustment
         need be made for a change in the par value or no par value of the
         Common Stock.

                  (k)    Whenever the Conversion Price is adjusted as herein
         provided, the Company shall promptly file with the Trustee and any
         conversion agent other than the Trustee an Officers' Certificate
         setting forth the Conversion Price after such adjustment and setting
         forth a brief statement of the facts requiring such adjustment.
         Promptly after delivery of such certificate, the Company shall prepare
         a notice of such adjustment of the Conversion Price setting forth the
         adjusted Conversion Price and the date on which each adjustment
         becomes effective and shall mail such notice of such adjustment of the
         Conversion Price to the holder of each Note at his last address
         appearing on the Note register provided for in Section 2.5, within
         twenty (20) days of the effective date of such adjustment. Failure to
         deliver such notice shall not effect the legality or validity of any
         such adjustment.

                  (l)    In any case in which this Section 15.5 provides that
         an adjustment shall become effective immediately after a Record Date
         for an event, the Company may defer until the occurrence of such event
         (i) issuing to the holder of any Note converted after



                                     -77-
<PAGE>   82

         such Record Date and before the occurrence of such event the
         additional shares of Common Stock issuable upon such conversion by
         reason of the adjustment required by such event over and above the
         Common Stock issuable upon such conversion before giving effect to
         such adjustment and (ii) paying to such holder any amount in cash in
         lieu of any fraction pursuant to Section 15.3.

                  (m)    For purposes of this Section 15.5, the number of
         shares of Common Stock at any time outstanding shall not include
         shares held in the treasury of the Company but shall include shares
         issuable in respect of scrip certificates issued in lieu of fractions
         of shares of Common Stock. The Company will not pay any dividend or
         make any distribution on shares of Common Stock held in the treasury
         of the Company.

                  (n)    In lieu of making any adjustment to the Conversion 
         Price pursuant to Section 15.5(e), the Company may elect to reserve an
         amount of cash for distribution to the holders of the Notes upon the
         conversion of the Notes so that any such holder converting Notes will
         receive upon such conversion, in addition to the shares of Common
         Stock and other items to which such holder is entitled, the full
         amount of cash which such holder would have received if such holder
         had, immediately prior to the Record Date for such distribution of
         cash, converted its Notes into Common Stock, together with any
         interest accrued with respect to such amount, in accordance with this
         Section 15.5(n). The Company may make such election by providing an
         Officers' Certificate to the Trustee to such effect on or prior to the
         payment date for any such distribution and depositing with the Trustee
         on or prior to such date an amount of cash equal to the aggregate
         amount the holders of the Notes would have received if such holders
         had, immediately prior to the Record Date for such distribution,
         converted all of the Notes into Common Stock. Any such funds so
         deposited by the Company with the Trustee shall be invested by the
         Trustee in marketable obligations issued or fully guaranteed by the
         United States government with a maturity not more than three (3)
         months from the date of issuance. Upon conversion of Notes by a
         holder, the holder will be entitled to receive, in addition to the
         Common Stock issuable upon conversion, an amount of cash equal to the
         amount such holder would have received if such holder had, immediately
         prior to the Record Date for such distribution, converted its Note
         into Common Stock, along with such holder's pro rata share of any
         accrued interest earned as a consequence of the investment of such
         funds. Promptly after making an election pursuant to this Section
         15.5(n), the Company shall give or shall cause to be given notice to
         all Noteholders of such election, which notice shall state the amount
         of cash per $1,000 principal amount of Notes such holders shall be
         entitled to receive (excluding interest) upon conversion of the Notes
         as a consequence of the Company having made such election.

         Section 15.6    Effect of Reclassification, Consolidation, Merger or
Sale. If any of the following events occur, namely (i) any reclassification or
change of the outstanding shares of



                                     -78-
<PAGE>   83

Common Stock (other than a change in par value, or from par value to no par
value, or from no par value to par value, or as a result of a subdivision or
combination), (ii) any consolidation, merger or combination of the Company with
another corporation as a result of which holders of Common Stock shall be
entitled to receive stock, securities or other property or assets (including
cash) with respect to or in exchange for such Common Stock, or (iii) any sale
or conveyance of the properties and assets of the Company as, or substantially
as, an entirety to any other corporation as a result of which holders of Common
Stock shall be entitled to receive stock, securities or other property or
assets (including cash) with respect to or in exchange for such Common Stock,
then the Company or the successor or purchasing corporation, as the case may
be, shall execute with the Trustee a supplemental indenture (which shall comply
with the Trust Indenture Act as in force at the date of execution of such
supplemental indenture if such supplemental indenture is then required to so
comply) providing that such Note shall be convertible into the kind and amount
of shares of stock and other securities or property or assets (including cash)
receivable upon such reclassification, change, consolidation, merger,
combination, sale or conveyance by a holder of a number of shares of Common
Stock issuable upon conversion of such Notes (assuming, for such purposes, a
sufficient number of authorized shares of Common Stock available to convert all
such Notes) immediately prior to such reclassification, change, consolidation,
merger, combination, sale or conveyance assuming such holder of Common Stock
did not exercise his rights of election, if any, as to the kind or amount of
securities, cash or other property receivable upon such consolidation, merger,
statutory exchange, sale or conveyance (provided that, if the kind or amount of
securities, cash or other property receivable upon such consolidation, merger,
statutory exchange, sale or conveyance is not the same for each share of Common
Stock in respect of which such rights of election shall not have been exercised
("non-electing share"), then for the purposes of this Section 15.6 the kind and
amount of securities, cash or other property receivable upon such
consolidation, merger, statutory exchange, sale or conveyance for each
non-electing share shall be deemed to be the kind and amount so receivable per
share by a plurality of the non-electing shares). Such supplemental indenture
shall provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article. If, in the case of
any such reclassification, change, consolidation, merger, combination, sale or
conveyance, the stock or other securities and assets receivable thereupon by a
holder of shares of Common Stock include shares of stock or other securities
and assets of a corporation other than the successor or purchasing corporation,
as the case may be, in such reclassification, change, consolidation, merger,
combination, sale or conveyance, then such supplemental indenture shall also be
executed by such other corporation and shall contain such additional provisions
to protect the interests of the holders of the Notes as the Board of Directors
shall reasonably consider necessary by reason of the foregoing, including to
the extent practicable the provisions providing for the repurchase rights set
forth in Article XVI herein.

         The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Notes, at his address appearing on the
Note register provided for in Section 2.5 of this Indenture, within twenty (20)
days after execution thereof. Failure to deliver



                                     -79-
<PAGE>   84

such notice shall not affect the legality or validity of such supplemental
indenture.

         The above provisions of this Section shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

         If this Section 15.6 applies to any event or occurrence, Section 15.5
shall not apply.

         Section 15.7    Taxes on Shares Issued. The issue of stock 
certificates on conversions of Notes shall be made without charge to the
converting Noteholder for any tax in respect of the issue thereof. The Company
shall not, however, be required to pay any tax which may be payable in respect
of any transfer involved in the issue and delivery of stock in any name other
than that of the holder of any Note converted, and the Company shall not be
required to issue or deliver any such stock certificate unless and until the
person or persons requesting the issue thereof shall have paid to the Company
the amount of such tax or shall have established to the satisfaction of the
Company that such tax has been paid.

         Section 15.8    Reservation of Shares; Shares to Be Fully Paid; 
Listing of Common Stock. The Company shall provide, free from preemptive
rights, out of its authorized but unissued shares or shares held in treasury,
sufficient shares to provide for the conversion of the Notes from time to time
as such Notes are presented for conversion.

         Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the shares of Common
Stock issuable upon conversion of the Notes, the Company will take all
corporate action which may, in the opinion of its counsel, be necessary in
order that the Company may validly and legally issue shares of such Common
Stock at such adjusted Conversion Price.

         The Company covenants that all shares of Common Stock issued upon
conversion of Notes will be fully paid and non-assessable by the Company and
free from all taxes, liens and charges with respect to the issue thereof.

         The Company further covenants that if at any time the Common Stock
shall be listed on the American Stock Exchange or any other national securities
exchange or automated quotation system the Company will, if permitted by the
rules of such exchange or automated quotation system, list and keep listed, so
long as the Common Stock shall be so listed on such exchange or automated
quotation system, all Common Stock issuable upon conversion of the Notes.

         Section 15.9    Responsibility of Trustee. The Trustee and any other
conversion agent shall not at any time be under any duty or responsibility to
any holder of Notes to determine whether any facts exist which may require any
adjustment of the Conversion Price, or with respect to the nature or extent or
calculation of any such adjustment when made, or with respect to the method
employed, or herein or in any supplemental indenture provided to be employed,
in 



                                     -80-
<PAGE>   85

making the same. The Trustee and any other conversion agent shall not be
accountable with respect to the validity or value (or the kind or amount) of
any shares of Common Stock, or of any securities or property, which may at any
time be issued or delivered upon the conversion of any Note; and the Trustee
and any other conversion agent make no representations with respect thereto.
Subject to the provisions of Section 8.1, neither the Trustee nor any
conversion agent shall be responsible for any failure of the Company to issue,
transfer or deliver any shares of Common Stock or stock certificates or other
securities or property or cash upon the surrender of any note for the purpose
of conversion or to comply with any of the duties, responsibilities or
covenants of the Company contained in this Article. Without limiting the
generality of the foregoing, neither the Trustee nor any conversion agent shall
be under any responsibility to determine the correctness of any provisions
contained in any supplemental indenture entered into pursuant to Section 15.6
relating either to the kind or amount of shares of stock or securities or
property (including cash) receivable by Noteholders upon the conversion of
their Notes after any event referred to in such Section 15.6 or to any
adjustment to be made with respect thereto, but, subject to the provisions of
Section 8.1, may accept as conclusive evidence of the correctness of any such
provisions, and shall be protected in relying upon, the Officers' Certificate
(which the Company shall be obligated to file with the Trustee prior to the
execution of any such supplemental indenture) with respect thereto.

         Section 15.10   Notice to Holders Prior to Certain Actions. In case:

                  (a)    the Company shall declare a dividend (or any other
         distribution) on its Common Stock (that would require an adjustment in
         the Conversion Price pursuant to Section 15.5); or

                  (b)    the Company shall authorize the granting to the 
         holders of its Common Stock of rights or warrants to subscribe for or
         purchase any share of any class or any other rights or warrants; or

                  (c)    of any reclassification of the Common Stock of the
         Company (other than a subdivision or combination of its outstanding
         Common Stock, or a change in par value, or from par value to no par
         value, or from no par value to par value), or of any consolidation or
         merger to which the Company is a party and for which approval of any
         shareholders of the Company is required, or of the sale or transfer of
         all or substantially all of the assets of the Company; or

                  (d)    of the voluntary or involuntary dissolution, 
         liquidation or winding-up of the Company;

the Company shall cause to be filed with the Trustee and to be mailed to each
holder of Notes at his address appearing on the Note register, provided for in
Section 2.5 of this Indenture, as promptly as possible but in any event at
least fifteen days prior to the applicable date hereinafter



                                     -81-
<PAGE>   86

specified, a notice stating (x) the date on which a record is to be taken for
the purpose of such dividend, distribution or rights or warrants, or, if a
record is not to be taken, the date as of which the holders of Common Stock of
record to be entitled to such dividend, distribution or rights are to be
determined, or (y) the date on which such reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation or winding-up is expected to
become effective or occur, and the date as of which it is expected that holders
of Common Stock of record shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.
Failure to give such notice, or any defect therein, shall not affect the
legality or validity of such dividend, distribution, reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.

                       REPURCHASE UPON A REPURCHASE EVENT

         Section 16.1    Repurchase Right.

                  (a)    If, at any time prior to April 1, 2006 there shall 
         occur a Repurchase Event, then each Noteholder shall have the right,
         at such holder's option, to require the Company to repurchase all of
         such holder's Notes, or any portion thereof (in principal amounts of
         $1,000 or integral multiples thereof), on the date (the "repurchase
         date") that is forty (40) calendar days after the date of the Company
         Notice (as defined in Section 16.2 below) of such Repurchase Event
         (or, if such 40th day is not a Business Day, the next succeeding
         Business Day). Such repurchase shall be made in cash at a price equal
         to 100% of the principal amount of Notes such holder elects to require
         the Company to repurchase, together with accrued interest, if any, to
         the repurchase date (the "Repurchase Price") (or, at the option of the
         Company, by delivery of Common Stock in accordance with the provisions
         of Section 16.3); provided, however, that if such repurchase date is
         April 1 or October 1 then the interest payable on such date shall be
         paid to the holder of record of the Note on the next preceding March
         15 or September 15, respectively. No Notes may be redeemed at the
         option of holders upon a Repurchase Event if there has occurred and is
         continuing an Event of Default, other than a default in the payment of
         the Repurchase Price with respect to such Notes on the repurchase
         date.

         Section 16.2    Notices; Method of Exercising Repurchase Right, Etc.

                  (a)    Unless the Company shall have theretofore called for
         redemption all of the outstanding Notes, on or before the fifteenth
         (15th) calendar day after the occurrence of a Repurchase Event, the
         Company or, at the written request of the Company, the Trustee, shall
         mail to all holders of record of the Notes a notice (the "Company
         Notice") in the form as prepared by the Company of the occurrence of
         the Repurchase Event and of the repurchase right set forth herein
         arising as a result thereof. The Company shall also deliver a copy of
         such notice of a repurchase right to the Trustee and cause a copy of
         such notice of a repurchase right, or a summary of the information
         contained therein, to be published once in a newspaper of general
         circulation in The City of New York. The Company Notice shall contain
         the following information:

                         (1)       the repurchase date,

                         (2)       the date by which the repurchase right must
                                   be exercised,

                         (3)       the last date by which the election to 
                                   require repurchase, if submitted, must be
                                   revoked;



                                     -83-

                         (4)       the Repurchase Price and whether the
                  Repurchase Price shall be payable in cash or Common Stock
                  and, if payable in Common Stock, the method of calculating
                  the amount of the Common Stock to be delivered upon the
                  repurchase as provided in Section 16.3(a);

                         (5)       a description of the procedure which a 
                  holder must follow to exercise a repurchase right, and

                         (6)       the Conversion Price then in effect, the 
                  date on which the right to convert the principal amount of
                  the Notes to be repurchased will terminate and the place or
                  places where Notes may be surrendered for conversion.

                  No failure of the Company to give the foregoing notices or
         defect therein shall limit any holder's right to exercise a repurchase
         right or affect the validity of the proceedings for the repurchase of
         Notes.

                  If any of the foregoing provisions are inconsistent with
applicable law, such law shall govern.

                  (b)    To exercise a repurchase right, a holder shall deliver
         to the Trustee on or before the thirty-fifth (35th) day after the
         Company Notice was delivered (i) written notice to the Company (or
         agent designated by the Company for such purpose) of the holder's
         exercise of such right, which notice shall set forth the name of the
         holder, the principal amount of the Notes to be repurchased, a
         statement that an election to exercise the repurchase right is being
         made thereby, and, in the event that the Repurchase Price shall be
         paid in shares of Common Stock, the name or names (with addresses) in
         which the certificate or certificates for shares of Common Stock shall
         be issued, and (ii) the Notes with respect to which the repurchase
         right is being exercised, duly endorsed for transfer to the Company.
         Election of repurchase by a holder shall be revocable at any time
         prior to, but excluding, the repurchase date, by delivering written
         notice to that effect to the Trustee prior to the close of business on
         the Business Day prior to the repurchase date.

                  (c)    If the Company fails to repurchase on the repurchase 
         date any Notes (or portions thereof) as to which the repurchase right
         has been properly exercised, then the principal of such Notes shall,
         until paid, bear interest to the extent permitted by applicable law
         from the repurchase date at the rate borne by the Note and each such
         Note shall be convertible into Common Stock in accordance with this
         Indenture (without giving effect to Section 16.2(b)) until the
         principal of such Note shall have been paid or duly provided for.

<PAGE>   89

                  (d)    Any Note which is to be repurchased only in part shall
         be surrendered to the Trustee duly endorsed for transfer to the
         Company and accompanied by appropriate evidence of genuineness and
         authority satisfactory to the Company and the Trustee duly executed
         by, the holder thereof (or his attorney duly authorized in writing),
         and the Company shall execute, and the Trustee shall authenticate and
         deliver to the holder of such Note without service charge, a new Note
         or Notes, containing identical terms and conditions, of any authorized
         denomination as requested by such holder in aggregate principal amount
         equal to and in exchange for the unrepurchased portion of the
         principal of the Note so surrendered.

                  (e)    On or prior to the repurchase date, the Company shall
         deposit with the Trustee or with a paying agent (or, if the Company is
         acting as its own paying agent, segregate and hold in trust as
         provided in Section 5.4) the Repurchase Price in cash for payment to
         the holder on the repurchase date; provided that if payment is to be
         made in cash, such cash payment is made on the repurchase date it must
         be received by the Trustee or paying agent, as the case may be, by
         10:00 a.m., New York City time, on such date; provided further that if
         the Repurchase Price is to be paid in shares of Common Stock, such
         shares of Common Stock are to be paid as promptly after the repurchase
         date as practicable.

                  (f)    Any issuance of shares of Common Stock in respect of 
         the Repurchase Price shall be deemed to have been effected immediately
         prior to the close of business on the repurchase date and the person
         or persons in whose name or names any certificate or certificates for
         shares of Common Stock shall be issuable upon such repurchase shall be
         deemed to have become on the repurchase date the holder or holders of
         record of the shares represented thereby; provided, however, that any
         surrender for repurchase on a date when the stock transfer books of
         the Company shall be closed shall constitute the person or persons in
         whose name or names the certificate or certificates for such shares
         are to be issued as the record holder or holders thereof for all
         purposes at the opening of business on the next succeeding day on
         which such stock transfer books are open. No payment or adjustment
         shall be made for dividends or distributions on any Common Stock
         issued upon repurchase of any Security declared prior to the
         repurchase date.

                  (g)    No fractions of shares shall be issued upon repurchase
         of Notes. If more than one Note shall be repurchased from the same
         holder and the Repurchase Price shall be payable in shares of Common
         Stock, the number of full shares which shall be issuable upon such
         repurchase shall be computed on the basis of the aggregate principal
         amount of the Notes so repurchased. Instead of any fractional share of
         Common Stock which would otherwise be issuable on the repurchase of
         any Note or Notes, the Company will deliver to the applicable holder
         its check for the current market value of such fractional share. The
         current market value of a fraction of a share is determined by
         multiplying the current market price of a full share by the fraction,
         and rounding the result to the nearest cent.

         For purposes of this Section, the current market price of a share of
         Common Stock is the Closing Price of the Common Stock on the Trading
         Day immediately preceding the repurchase date.

                  (h)    Any issuance and delivery of certificates for shares
         of Common Stock on repurchase of Notes shall be made without charge to
         the holder of Notes being repurchased for such certificates or for any
         tax or duty in respect of the issuance or delivery of such
         certificates or the securities represented thereby; provided, however,
         that the Company shall not be required to pay any tax or duty which
         may be payable in respect of (i) income of the holder or (ii) any
         transfer involved in the issuance or delivery of certificates for
         shares of Common Stock in a name other than that of the holder of the
         Notes being repurchased, and no such issuance or delivery shall be
         made unless and until the person requesting such issuance or delivery
         has paid to the Company the amount of any such tax or duty or has
         established, to the satisfaction of the Company, that such tax or duty
         has been paid.

                  (i)    All Notes delivered for repurchase shall be delivered
         to the Trustee to be canceled in accordance with the provisions of
         Section 2.8.

         Section 16.3    Conditions to the Company's Election to Pay the
Repurchase Price in Common Stock.

         The Company may elect to pay the Repurchase Price by delivery of
shares of Common Stock pursuant to Section 16.1 if and only if the following
conditions shall have been satisfied:

         (a)   The shares of Common Stock deliverable in payment of the
Repurchase Price shall have a fair market value as of the repurchase date of
not less than the Repurchase Price. For purposes of Section 16.1 and this
Section 16.3, the fair market value of shares of Common Stock shall be
determined by the Company and shall be equal to 95% of the average of the
Closing Prices of the Common Stock for the five consecutive Trading Days
immediately preceding and including the third Trading Day prior to the
repurchase date;

         (b)   The Repurchase Price shall be paid only in cash in the event any
shares of Common Stock to be issued upon repurchase of Notes hereunder (i)
require registration under any federal securities law before such shares may be
freely transferrable without being subject to any transfer restrictions under
the Securities Act upon repurchase and if such registration is not completed or
does not become effective prior to the repurchase date, and/or (ii) require
registration with or approval of any governmental authority under any state law
or any other federal law before such shares may be validly issued or delivered
upon repurchase and if such registration is not completed or does not become
effective or such approval is not obtained prior to the repurchase date;



                                     -86-
<PAGE>   91

         (c)   Payment of the Repurchase Price may not be made in Common Stock
unless such stock is, or shall have been, or approved for quotation on the
Nasdaq National Market or listed on a national securities exchange, in either
case, prior to the repurchase date; and

         (d)   All shares of Common Stock which may be issued upon repurchase
of the Notes will be issued out of the Company's authorized but unissued Common
Stock and, will upon issue, be duly and validly issued and fully paid and
non-assessable and free of any preemptive rights.

         If all of the conditions set forth in this Section 16.3 are not
satisfied in accordance with the terms thereof, the Repurchase Price shall be
paid by the Company only in cash.

         Section 16.4    Certain Definitions. For purposes of this Article XVI:

                  (a)    the term "beneficial owner" shall be determined in

         original execution of this Indenture, promulgated by the Securities
         and Exchange Commission pursuant to the Exchange Act;

                  (b)    the term "person" or "group" shall include any 
         syndicate or group which would be deemed to be a "person" under

                  (c)    the term "Continuing Director" means at any date a 
         member of the Company's Board of Directors (i) who was a member of
         such board on March 19, 1999 or (ii) who was nominated or elected by
         at least a majority of the directors who were Continuing Directors at
         the time of such nomination or election or whose election to the
         Company's Board of Directors was recommended or endorsed by at least a
         majority of the directors who were Continuing Directors at the time of
         such nomination or election or such lesser number comprising a
         majority of a nominating committee if authority for such nominations
         or elections has been delegated to a nominating committee whose
         authority and composition have been approved by at least a majority of
         the directors who were Continuing Directors at the time such committee
         was formed. (Under this definition, if the Board of Directors of the
         Company as of the date of this Indenture were to approve a new
         director or directors and then resign, no Change in Control would
         occur even though the current Board of Directors would thereafter
         cease to be in office).

                  (d)    the term "Repurchase Event" means a Change in Control
         or a Termination of Trading.

                  (e)    a "Change in Control" shall be deemed to have occurred
         when (i) any "person" or "group" (as such terms are used in Sections
         13(d) and 14(d) of the Exchange Act) is or becomes the "beneficial
         owner" (as defined in Rules 13-d3 and 13-d5 under the

         Exchange Act) of shares representing more than 50% of the combined
         voting power of the then outstanding securities entitled to vote
         generally in elections of directors of the Company (the "Voting
         Stock"); (ii) approval by stockholders of the Company of any plan or
         proposal for the liquidation, dissolution or winding up of the
         Company; (iii) the Company (A) consolidates with or merges into any
         other corporation or any other corporation merges into the Company,
         and in the case of any such transaction, the outstanding Common Stock
         of the Company is changed or exchanged into other assets or securities
         as a result, unless the stockholders of the Company immediately before
         such transaction own, directly or indirectly immediately following
         such transaction, at least 51% of the combined voting power of the
         outstanding voting securities of the corporation resulting from such
         transaction in substantially the same proportion as their ownership of
         the Voting Stock immediately before such transaction, or (B) conveys,
         transfers or leases all or substantially all of its assets to any
         person; or (iv) any time Continuing Directors do not constitute a
         majority of the Board of Directors of the Company (or, if applicable,
         a successor corporation to the Company); provided that a Change in
         Control shall not be deemed to have occurred if either (x) the Closing
         Price (as defined in Section 15.5(h)(1) hereof) of the Common Stock
         for any five (5) Trading Days during the ten (10) Trading Days
         immediately preceding the Change in Control is at least equal to 105%
         of the Conversion Price in effect on the date on which the Change in
         Control occurs or (y) in the case of a merger or consolidation
         otherwise constituting a Change in Control, all of the consideration
         (excluding cash payments for fractional shares) in such merger or
         consolidation constituting the Change in Control consists of common
         stock traded on a United States national securities exchange or quoted
         on the Nasdaq National Market (or which will be so traded or quoted
         when issued or exchanged in connection with such Change in Control)
         and as a result of such transaction or transactions such Notes become
         convertible solely into such common stock.

                  (f)    a "Termination of Trading" shall have occurred if the
         Common Stock (or other common stock into which the Notes are then
         convertible) is neither listed for trading on a United States national
         securities exchange nor approved for trading on an established
         automated over-the-counter trading market in the United States.

         Section 17.11   Authenticating Agent. The Trustee may appoint an 
authenticating agent which shall be authorized to act on its behalf and subject
to its direction in the authentication and delivery of Notes in connection with
the original issuance thereof and transfers and exchanges of Notes hereunder,
including under Sections 2.4, 2.5, 2.6, 2.7 and 3.3, as fully to all intents
and purposes as though the authenticating agent had been expressly authorized
by this Indenture and those Sections to authenticate and deliver Notes. For all
purposes of this Indenture, the authentication and delivery of Notes by the
authenticating agent shall be deemed to be authentication and delivery of such
Notes "by the Trustee" and a certificate of authentication executed on behalf
of the Trustee by an authenticating agent shall be deemed to satisfy any
requirement hereunder or in the Notes for the Trustee's certificate of
authentication. Such authenticating agent shall at all times be a person
eligible to serve as trustee hereunder pursuant to Section 8.9.

         Any corporation into which any authenticating agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any authenticating agent
shall be a party, or any corporation succeeding to the corporate trust business
of any authenticating agent, shall be the successor of the authenticating agent
hereunder, if such successor corporation is otherwise eligible under this
Section, without the execution or filing of any paper or any further act on the
part of the parties hereto or the authenticating agent or such successor
corporation.

         Any authenticating agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company. The Trustee may at any
time terminate the agency of any authenticating agent by giving written notice
of termination to such authenticating agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
any authenticating agent shall cease to be eligible under this Section, the
Trustee shall promptly appoint a successor authenticating agent (which may be
the Trustee), shall give written notice of such appointment to the Company and
shall mail notice of such appointment to all holders of Notes as the names and
addresses of such holders appear on the Note register.

         The Trustee agrees to pay to the authenticating agent from time to
time reasonable compensation for its services (to the extent pre-approved by
the Company in writing), and the Trustee shall be entitled to be reimbursed for
such pre-approved payments, subject to Section 8.6.

         The provisions of Sections 8.2, 8.3, 8.4, 9.3 and this Section 17.11
shall be applicable to any authenticating agent.

         Section 17.12   Execution in Counterparts. This Indenture may be 
executed in any number of counterparts, each of which shall be an original, but
such counterparts shall together constitute but one and the same instrument.

         State Street Bank and Trust Company hereby accepts the trusts in this
Indenture declared and provided, upon the terms and conditions hereinabove set
forth.

                              SPORTSLINE USA, INC.

                    5% Convertible Subordinated Note Due 2006


     This Note is one of a duly authorized issue of Notes of the Company,
designated as its 5% Convertible Subordinated Notes due 2006 (herein called the
"Notes"), limited to the aggregate principal amount of $150,000,000 (or
$200,000,000 if the option set forth in Section 2(b) of the Purchase Agreement
is exercised in full by the Initial Purchasers) all issued or to be issued under
and pursuant to an Indenture dated as of March 15, 1999 (herein called the
"Indenture"), between the Company and State Street Bank and Trust Company
(herein called the "Trustee"), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Company and the holders of the Notes.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of, premium, if any, and accrued
interest (including Liquidated Damages, if any) on all Notes may be declared,
and upon said declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions provided in the Indenture.

     The Indenture contains provisions permitting the Company and the Trustee in
certain limited circumstances, without the consent of the holders of the Notes,
and in other circumstances, with the consent of the holders of not less than a
majority in aggregate principal amount of the Notes at the time outstanding,
evidenced as in the Indenture provided, to execute supplemental indentures
adding any provisions to or changing in any manner or eliminating any of the
provisions of the Indenture or of any supplemental indenture or modifying in any
manner the rights of the holders of the Notes; provided, however, that no such
supplemental indenture shall (i) extend the fixed maturity of any Note, or
reduce the rate or extend the time of payment of interest thereon, or reduce the
principal amount thereof or premium, if any, thereon, or reduce any amount
payable on redemption or repurchase thereof, impair, or change in any respect
adverse to the holder of Notes, the obligation of the Company to repurchase any
Note at the option of the holder upon the happening of a Repurchase Event, or
impair or adversely affect the right of any Noteholder to institute suit for the
payment thereof, or change the currency in which the Notes are payable, or
impair or change in any respect adverse to the Noteholders the right to convert
the Notes into Common Stock subject to the terms set forth herein, including
Section 15.6, or modify the provisions of this Indenture with respect to the
subordination of the Notes in a manner adverse to the Noteholders, without the
consent of the holder of each Note so affected, or (ii) reduce the aforesaid
percentage of Notes, the holders of which are required to consent to any such
supplemental indenture, without the consent of the holders of all Notes then

                                      A-6

outstanding. It is also provided in the Indenture that, prior to any declaration
accelerating the maturity of the Notes, the holders of a majority in aggregate
principal amount of the Notes at the time outstanding may on behalf of the
holders of all of the Notes waive any past default or Event of Default under the
Indenture and its consequences except (i) a default in the payment of interest
or premium, if any, on, or the principal of, the Notes when due, (ii) a failure
by the Company to convert any Notes into Common Stock or (iii) a default in
respect of a covenant or provisions of the Indenture which under Article XI
cannot be modified or amended without the consent of the holders of all Notes
then outstanding. Any such consent or waiver by the holder of this Note (unless
revoked as provided in the Indenture) shall be conclusive and binding upon such
holder and upon all future holders and owners of this Note and any Notes which
may be issued in exchange or substitution hereof, irrespective of whether or not
any notation thereof is made upon this Note or such other Notes.

     The indebtedness evidenced by the Notes is, to the extent and in the manner
provided in the Indenture, expressly subordinate and subject in right of payment
to the prior payment in full in cash or other payment satisfactory to the
holders of Senior Indebtedness of all Senior Indebtedness of the Company, as
defined in the Indenture, whether outstanding at the date of the Indenture or
thereafter incurred, and this Note is issued subject to the provisions of the
Indenture with respect to such subordination. Each holder of this Note, by
accepting the same, agrees to and shall be bound by such provisions and
authorizes the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination so provided and appoints the Trustee
his attorney in fact for such purpose.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, premium, if any, and
interest on this Note at the place, at the respective times, at the rate and in
the lawful money herein prescribed.

     Interest on the Notes shall be computed on the basis of a 360-day year
comprised of twelve 30-day months.

     The Notes are issuable in registered form without coupons in denominations
of $1,000 principal amount and integral multiples thereof. At the office or
agency of the Company referred to on the face hereof, and in the manner and
subject to the limitations provided in the Indenture, without payment of any
service charge but with payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration or
exchange of Notes, Notes may be exchanged for a like aggregate principal amount
of Notes of other authorized denominations.

     The Notes will not be redeemable at the option of the Company prior to
April 2, 2002. On or after such date and prior to maturity the Notes may be
redeemed at the option of the Company as 

                                      A-7

a whole, or from time to time in part, upon mailing a notice of such redemption
not less than 30 nor more than 60 days before the date fixed for redemption to
the holders of Notes at their last registered addresses, all as provided in the
Indenture, at the following redemption prices (expressed as percentages of the
principal amount), together in each case with accrued interest, if any, to, but
excluding, the date fixed for redemption.

     If redeemed during the 12-month period beginning April 1 (April 2, 2002
through March 31, 2003 in the case of the first such period):

and 100% at April 1, 2006; provided that if the date fixed for redemption is a
April 1 or October 1, then the interest payable on such date shall be paid to
the holder of record on the next preceding March 15 or September 15,
respectively.

         The Notes are not subject to redemption through the operation of any
sinking fund.

         Upon the occurrence of a "Repurchase Event," the Noteholder has the
right, at such holder's option, to require the Company to repurchase all or any
portion of such holder's Notes on the 40th calendar day (or, if such 40th day is
not a Business Day, the next succeeding Business Day) after notice of such
Repurchase Event at a price equal to 100% of the principal amount of the Notes
such holder elects to require the Company to repurchase, together in each case
with accrued interest to the date fixed for repurchase; provided that if such
repurchase date is April 1 or October 1, then the interest payable on such date
shall be paid to the holder of record of the Note on the next preceding March 15
or September 15, respectively. The Company or, at the written request of the
Company, the Trustee shall mail to all holders of record of the Notes a notice
of the occurrence of a Repurchase Event and of the repurchase right arising as a
result thereof on or before the fifteenth (15th) calendar day after the
occurrence of such Repurchase Event. Payment of the repurchase price may be made
in shares of the Company's Common Stock under certain circumstances as provided
in Section 16.3 of the Indenture.

         Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time following the date of original issuance of the
Notes and prior to the close of business on 


                                       A-8
<PAGE>   105

April 1, 2006, (except that with respect to any Note or portion of a Note which
shall be called for redemption, prior to the close of business on the Business
Day next preceding the date fixed for redemption) (unless the Company shall
default in payment due upon redemption), to convert the principal hereof or any
portion of such principal which is $1,000 or an integral multiple thereof, into
that number of fully paid and non-assessable shares of Company's Common Stock,
as said shares shall be constituted at the date of conversion, obtained by
dividing the principal amount of this Note or portion thereof to be converted by
the conversion price of an amount equal to $1,000 divided by 15.355 or such
conversion price as adjusted from time to time as provided in the Indenture,
upon surrender of this Note, together with a conversion notice as provided in
the Indenture and this Note, to the Company at the office or agency of the
Company maintained for that purpose in the Borough of Manhattan, The City of New
York, or at the option of such holder, the Corporate Trust Office, and, unless
the shares issuable on conversion are to be issued in the same name as this
Note, duly endorsed by, or accompanied by instruments of transfer in form
satisfactory to the Company duly executed by, the holder or by his duly
authorized attorney. No adjustment in respect of interest or dividends will be
made upon any conversion; provided, however, that if this Note shall be
surrendered for conversion during the period from the close of business on any
record date for the payment of interest through the close of business on the
Business Day next preceding the following interest payment date, this Note
(unless the Note or the portion thereof being converted shall have been called
for redemption pursuant to a redemption notice mailed to the Noteholders in
accordance with Section 3.2 of the Indenture) must be accompanied by an amount,
in funds acceptable to the Company, equal to the interest otherwise payable on
such interest payment date on the principal amount being converted. No
fractional shares of Common Stock will be issued upon any conversion, but an
adjustment in cash will be paid to the holder, as provided in the Indenture, in
respect of any fraction of a share which would otherwise be issuable upon the
surrender of any Note or Notes for conversion.

         Any Notes called for redemption, unless surrendered for conversion on
or before the close of business on the date fixed for redemption, may be deemed
to be purchased from the holder of such Notes at an amount equal to the
applicable redemption price, together with accrued interest to the date fixed
for redemption, by one or more investment bankers or other purchasers who may
agree with the Company to purchase such Notes from the holders thereof and
convert them into Common Stock of the Company and to make payment for such Notes
as aforesaid to the Trustee in trust for such holders.

         Upon due presentment for registration of transfer of this Note at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, or at the option of the holder of this Note, at the Corporate Trust
Office, a new Note or Notes of authorized denominations for an equal aggregate
principal amount will be issued to the transferee in exchange thereof, subject
to the limitations provided in the Indenture, without charge except for any tax
or other governmental charge imposed in connection therewith.

         The Company, the Trustee, any authenticating agent, any paying agent,

be overdue and notwithstanding any notation of ownership or other writing hereon
made by anyone other than the Company or any Note registrar), for the purpose of
receiving payment hereof, or on account hereof, for the conversion hereof and
for all other purposes, and neither the Company nor the Trustee nor any other
authenticating agent nor any paying agent nor any other conversion agent nor any
Note registrar shall be affected by any notice to the contrary. All payments
made to or upon the order of such registered holder shall, to the extent of the
sum or sums paid, satisfy and discharge liability for monies payable on this
Note.

         No recourse for the payment of the principal of or any premium or
interest on this Note, or for any claim based hereon or otherwise in respect
hereof, and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any indenture supplemental thereto or in any
Note, or because of the creation of any indebtedness represented thereby, shall

or subsidiary, as such, past, present or future, of the Company or of any
successor corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

         Rule 501(a)(1), (2) or (3) under the Securities Act of 1933 (the
         "Securities Act") or an entity in which all of the equity owners are
         accredited investors within the meaning of Rule 501(a)(1), (2) or (3)
         under the Securities Act;

                      2. (A) any purchase of Notes by us will be for our own
         account or for the account of one or more other Institutional
         Accredited Investors (defined below) or as fiduciary for the account of
         one or more trusts, each of which is an "accredited investor" within
         the meaning of Rule 501(a)(7) under the Securities Act (such trusts,
         together with accredited investors within the meaning of Rule
         501(a)(1), (2) or (3) under the Securities Act, an "Institutional
         Accredited Investor") and for each of which we exercise sole investment
         discretion or (B) we are a "bank," within the meaning of Section

         acquire Notes having a minimum principal amount of not less than
         $100,000 for our own account or for any separate account for which we
         are acting;

                      4. we have such knowledge and experience in financial and
         business matters that we are capable of evaluating the merits and risks
         of purchasing the Notes; and

                      5. we are not acquiring Notes with a view to distribution
         thereof or with any present intention of offering or selling Notes or
         the Common Stock issuable upon conversion thereof, except as permitted
         below; provided that the disposition of our property and property of
         any accounts for which we are acting as fiduciary shall remain at all
         times within our control.

         We understand that the Notes are being offered in a transaction not
involving any public offering within the United States within the meaning of the
Securities Act and that the Notes and the shares of Common Stock issuable upon
conversion thereof (the "Securities") have not been registered under the
Securities Act, and we agree, on our own behalf and on behalf of each account
for which we acquire any Securities, that if in the future we decide to resell
or otherwise transfer such Securities, such Securities may be resold or
otherwise transferred only (i) to the Company or any subsidiary thereof, or (ii)
to a person who is a "qualified institutional buyer" (as defined in Rule 144A
under the Securities Act) in a transaction meeting the requirements of Rule
144A, or (iii) to an Institutional Accredited Investor that, prior to such
transfer, furnishes to the Trustee or transfer agent for such Securities a
signed letter containing certain representations and agreements relating to the
restrictions on transfer of such Securities (the form of which letter can be
obtained from such Trustee or transfer agent), or (iv) pursuant to the exemption
from registration provided by Rule 144 under the Securities Art (if applicable),
or (v) pursuant to a registration statement which has been declared effective
under the Securities Act, and in each case, in accordance with any applicable
securities laws of any State of the United States or any other applicable
jurisdiction and in accordance with the legends set forth on the Securities. We
further agree to provide any person purchasing any of the Securities other than
pursuant to clause (v) above from us a notice advising such purchaser that
resales of such securities are restricted as stated herein. We understand that
the Trustee for the Notes and/or the transfer agent for the Common Stock will
not be required to accept for registration of transfer any Notes or any shares
of Common Stock issued upon conversion of the Notes except upon presentation of
evidence satisfactory to the Company that the foregoing restrictions on transfer
have been complied with. We further understand that any Notes and any
certificates representing Common Stock will be in the form of definitive
physical certificates and that such certificates will bear a legend reflecting
the substance of this paragraph other than certificates representing Common
Stock transferred pursuant to clause (v) above.

         We acknowledge that the Company, others and you will rely upon our
confirmations, acknowledgments and agreements set forth herein, and we agree to
notify you promptly in writing if any of our representations or warranties
herein ceases to be accurate and complete.

                  underwritten registration or underwritten offering: A
registration in connection with which securities of the Company are sold to one
or more underwriters for reoffering to the public pursuant to an effective
Registration Statement.

                  References herein to the term "Holders of a majority in
aggregate principal amount of Transfer Restricted Securities" or words to a
similar effect shall mean, with respect to any request, notice, demand,
objection or other action by the Holders hereunder or pursuant hereto (each, an
"Act"), registered Holders of a number of shares of then-outstanding Common
Stock constituting Transfer Restricted Securities and an aggregate principal
amount of then outstanding Notes constituting Transfer Restricted Securities,
such that the sum of such shares of Common Stock and the shares of Common Stock
issuable upon conversion of such Notes constitutes in excess of 50% of the sum
of all of the then-outstanding shares of Common Stock constituting Transfer
Restricted Securities and the number of shares of Common Stock issuable upon
conversion of then-outstanding Notes constituting Transfer Restricted
Securities. For purposes of the preceding sentence, Transfer Restricted
Securities owned, directly or indirectly, by the Company or its Affiliates shall
be deemed not to be outstanding.

         2.       Shelf Registration Statement

                  (a) The Company agrees to file with the SEC on or prior to the
Filing Date a Registration Statement for an offering to be made on a continuous
basis pursuant to Rule 415 covering all of the Transfer Restricted Securities or
separate Registration Statements for an offering to be made on a continuous
basis pursuant to Rule 415 covering all of the Notes constituting Transfer
Restricted Securities and all of the Common Stock constituting Transfer
Restricted Securities, respectively (such Registration Statement or Statements,
collectively, the "Shelf Registration Statement"). Each Shelf Registration
Statement shall be on Form S-3 under the Securities Act or another appropriate
form selected by the Company permitting registration of such Transfer Restricted
Securities for resale by the Holders in the manner or manners reasonably
designated by Holders of a majority in aggregate principal amount of Transfer
Restricted Securities being sold (including, without limitation, up to three
underwritten offerings). The Company shall not permit any securities other than
the Transfer Restricted Securities to be included in any Shelf Registration
Statement. The Company shall use its best efforts to cause each Shelf
Registration Statement to be declared effective pursuant to the Securities Act
as promptly as is practicable following the filing thereof and to keep each
Shelf Registration Statement continuously effective under the Securities Act for
two years after the latest date of original issuance of 


                                      -5-
<PAGE>   6


any of the Notes (subject to extension pursuant to Sections 2(d) hereof) (the
"Effectiveness Period"), or such shorter period ending when there cease to be
any Transfer Restricted Securities outstanding.

                  (b) Supplements and Amendments. The Company shall use its best
efforts to keep each Shelf Registration Statement continuously effective by
supplementing and amending the Shelf Registration Statement if required by the
rules, regulations or instructions applicable to the registration form used for
such Shelf Registration Statement, if required by the Securities Act or if
reasonably requested by the Holders of a majority in aggregate principal amount
of the Transfer Restricted Securities or by any underwriter of such Transfer
Restricted Securities; provided, however, that the Effectiveness Period shall be
extended as provided in Section 2(d) hereof.

                  (c) Selling Securityholder Information. Each Holder of
Transfer Restricted Securities agrees that if such Holder wishes to sell
Transfer Restricted Securities pursuant to a Shelf Registration Statement and
related Prospectus, it will do so only in accordance with this Section 2. Each
Holder of Transfer Restricted Securities wishing to sell Transfer Restricted
Securities pursuant to a Shelf Registration Statement and related Prospectus
agrees to deliver a Notice and Questionnaire that includes such information
regarding the distribution of its Transfer Restricted Securities as is required
by law to be disclosed by the Holder in the applicable Registration Statement
(the "Requisite Information") to the Company prior to any intended distribution
of Transfer Restricted Securities under the Shelf Registration Statement. From
and after the date the Shelf Registration Statement becomes effective, the
Company shall, as promptly as is practicable after the date a Notice and
Questionnaire is delivered, and in any event within five (5) Business Days after
such date, (i) if required by applicable law, file with the SEC a post-effective
amendment to the Shelf Registration Statement or prepare and, if required by
applicable law, file a supplement to the related Prospectus or a supplement or
amendment to any document incorporated therein by reference or file any other
required document so that the Holder delivering such Notice and Questionnaire is
named as a selling securityholder in the Shelf Registration Statement and the
related Prospectus in such a manner as to permit such Holder to deliver such
Prospectus to purchasers of the Transfer Restricted Securities in accordance
with applicable law and, if the Company shall file a post-effective amendment to
the Shelf Registration Statement, use its reasonable best efforts to cause such
post-effective amendment to be declared effective under the Securities Act as
promptly as is practicable, but in any event by the date that is forty-five (45)
days after the date such post-effective amendment is required by this clause to
be filed; (ii) provide such Holder copies of any documents filed pursuant to
Section 2(c)(i); and (iii) notify such Holder as promptly as practicable after
the effectiveness under the Securities Act of any post-effective amendment filed
pursuant to Section 2(c)(i); provided, that if such Notice and Questionnaire is
delivered during the time a Holder receives a notice from the Company pursuant
to Section 2(d) that the use of the Prospectus shall be discontinued, the
Company shall so inform the Holder delivering such Notice and Questionnaire and
shall take the actions set forth in clauses (i), (ii) and (iii) above upon such
time the use of the Prospectus may be resumed, provided, further, that if under
applicable law the Company has more than one option as to the type or manner of
making any such filing, it will make the required filing or filings in the
manner or of a type reasonably expected to result in the earliest availability
of the Prospectus for effecting resales of Transfer Restricted Securities.

                  If any such Registration Statement refers to any Holder by
name or otherwise as the holder of any securities of the Company, then such
Holder shall have the right to require, in the event that such reference to such
Holder by name or otherwise is not required by the Securities Act or any 


                                      -6-

<PAGE>   7

similar Federal statute then in force, the deletion of the reference to such
Holder in such Registration Statement at any time subsequent to the time that
such reference ceases to be required.

                  (d) Certain Notices; Suspension of Sales. Each Holder agrees
by acquisition of such Transfer Restricted Securities that, upon receipt of any
notice from the Company of the happening of any event of the kind described in
Section 4(c)(ii), 4(c)(iii), 4(c)(v) or 4(c)(vi) hereof, such Holder will
forthwith discontinue disposition of such Transfer Restricted Securities covered
by such Registration Statement and Prospectus (other than in transactions exempt
from the registration requirements under the Securities Act) until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Sections 4(c)(i) and 4(k) hereof, or until it is advised in writing (the
"Advice") by the Company that the use of the applicable Prospectus may be
resumed, and, in either case, has received copies of any additional or
supplemental filings that are incorporated or deemed to be incorporated by
reference in such Prospectus. If the Company shall give any such notice, the
Effectiveness Period shall be extended by the number of days during such period
from and including the date of the giving of such notice to and including the
date when each Holder shall have received (x) the copies of the supplemented or
amended Prospectus contemplated by Sections 4(c)(i) and 4(k) hereof or (y) the
Advice, and, in either case, has received copies of any additional or
supplemental filings that are incorporated or deemed to be incorporated by
reference in such Prospectus.

         3.       Liquidated Damages

                  (a) The Company and the Purchasers agree that the Holders will
suffer damages if the Company fails to fulfill its obligations pursuant to
Section 2 hereof and that it would not be possible to ascertain the extent of
such damages. Accordingly, the Company hereby agrees to pay liquidated damages
("Liquidated Damages") under the circumstances and to the extent set forth
below:

                       (i)  to each Holder if the Shelf  Registration  Statement
                  has not been filed with the SEC on or prior to the Filing
                  Date; or

                      (ii)  to each Holder if each Shelf Registration Statement 
                  is not declared effective by the SEC on or prior to the
                  applicable Effectiveness Target Date;

                     (iii)  to each Holder any Shelf Registration Statement
                  ceases to be effective or usable at any time during the
                  Effectiveness Period (without being succeeded on the same day
                  immediately by a post-effective amendment or supplement to
                  such Registration Statement that cures such failure and that
                  is itself, in the case of post-effective amendment,
                  immediately declared effective) for a period of time which
                  shall exceed 90 days in the aggregate in any period of 365
                  consecutive days; or

                      (iv)  to the particular Holder affected by the Company's 
                  failure to perform its obligations set forth in Section 2(c)
                  within the time period required therein;

(any of the foregoing, a "Registration Default"); provided that the fact that a
Shelf Registration Statement is not usable by a particular Holder at any given
time solely as a result of the failure of such Holder to provide Requisite
Information with respect to it shall not be relevant for purposes of clause
(iii) above unless such Holder shall have provided such information to the
Company and the Company shall have 


                                      -7-
<PAGE>   8


failed to file an appropriate Prospectus supplement or post-effective amendment
to the Registration Statement. In the event of any such Registration Default,
the Company shall accrue Liquidated Damages to each applicable Holder during the
first 90-day period immediately in an amount equal to $.05 per week per $1,000
principal amount of Notes held by such Holder and, if applicable, on an
equivalent basis per share (subject to adjustment in the event of any stock
split, stock combination, stock dividends and the like) of Common Stock
constituting Transfer Restricted Securities held by such Holder for each week or
portion thereof that the Registration Default continues. The weekly rate at
which such Liquidated Damages accrue shall increase by an additional $.05 per
$1,000 principal amount of Notes and, if applicable, an equivalent amount per
week per share (subject to adjustment as set forth above) of Common Stock
constituting Transfer Restricted Securities for each subsequent continuing
90-day period following the occurrence of such Registration Default until all
Registration Defaults have been cured; provided, however, that Liquidated
Damages shall not at any time exceed $.25 per week per $1,000 principal amount
of Notes or, as applicable, an equivalent amount per week per share (subject to
adjustment as set forth above) of Common Stock constituting Transfer Restricted
Securities. Following the cure of all Registration Defaults, the accrual of
Liquidated Damages shall cease (without in any way limiting the effect of any
subsequent Registration Default). A Registration Default under clause (i) above
shall be cured on the date that the applicable Shelf Registration Statement is
filed with the SEC; a Registration Default under clause (ii) above shall be
cured on the date that the applicable Shelf Registration Statement is declared
effective by the SEC; a Registration Default under clause (iii) above shall be
cured on the date the applicable Shelf Registration Statement is declared
effective or otherwise usable; and a Registration Default under clause (iv)
above shall be cured on the date the applicable prospectus supplement to the
Shelf Registration Statement is filed or the post-effective amendment with
respect to such Shelf Registration Statement is declared effective.

                  (b) The Company shall notify the Trustee within one Business
Day after each and every date on which a Registration Default occurs. Liquidated
Damages shall be paid by the Company to the Record Holders on each Damages
Payment Date in the same manner as interest is paid under the Indenture, in the
case of the Notes, and by mailing checks to their registered addresses in the
register of the Company for the Common Stock, in the case of shares of Common
Stock; provided, however, that any Liquidated Damages accrued with respect to
any Note or portion thereof called for redemption on a redemption date,
repurchased in connection with a Repurchase Event (as defined in the Indenture)
on a repurchase date, or converted into shares of Common Stock on a conversion
date prior to the Damages Payment Date, shall, in any such event, be paid
instead to the Holder who submitted such Note or portion thereof for redemption,
repurchase or conversion on the applicable redemption date, repurchase date or
conversion date, as the case may be, on such date (promptly following the
conversion date, in the case of conversion of a Note). In no event shall the
Company be required to pay Liquidated Damages in excess of the applicable
maximum weekly amount set forth above, regardless of whether one or multiple
Registration Defaults shall exist.

                  (c) All of the Company's obligations set forth in this Section
3 which are unsatisfied to any extent with respect to any Transfer Restricted
Securities at the time such security ceases to be a Transfer Restricted Security
shall survive until such time as all such obligations with respect to such
security have been satisfied in full (notwithstanding the earlier termination of
this Agreement).


                                      -8-

<PAGE>   9

                  (d) Any payments due and payable pursuant to this Section 3
with respect to any Notes shall be subject to the provisions of Article IV of
the Indenture as if such payments were additional interest on the Notes.

                  (e) The parties hereto agree that the Liquidated Damages
provided for in this Section 3 constitute a reasonable estimate of the damages
that may be incurred by holders of record of Transfer Restricted Securities by
reason of the failure of the Shelf Registration Statement to be filed or
declared effective or unavailable (absolutely or as a practical matter) for
effecting resales of Transfer Restricted Securities in accordance with the
provisions hereof. Notwithstanding the foregoing, the parties agree that the
sole contractual damages payable for a violation of the terms of this Agreement
with respect to which Liquidated Damages are expressly provided shall be such
Liquidated Damages. Nothing in this Section 3(e), however, shall preclude a
holder of Transfer Restricted Securities from pursuing or obtaining specific
performance or other equitable relief with respect to the Company's failure to
pay Liquidated Damages pursuant to this Agreement.

         4. Registration Procedures. In connection with the Company's
registration obligations hereunder, the Company shall effect such registrations
on the appropriate form selected by the Company to permit the resale of Transfer
Restricted Securities in accordance with the intended method or methods of
disposition thereof, and pursuant thereto the Company shall as expeditiously as
reasonably possible:

                  (a) No fewer than five Business Days prior to the initial
filing of a Registration Statement or Prospectus and no fewer than two Business
Days prior to the filing of any amendment or supplement thereto (excluding,
unless requested, any document that would be incorporated or deemed to be
incorporated therein by reference), furnish to the registered (as of the most
recent reasonably practicable date which shall not be more than two Business
Days prior to the date such document is personally delivered, delivered to a
next-day courier, deposited in the mail or telecopied, as the case may be)
Holders, Special Counsel and the managing underwriters, if any, copies of all
such documents proposed to be filed (excluding, unless requested, those
incorporated or deemed to be incorporated by reference) and cause the officers
and directors of the Company, counsel to the Company and independent certified
public accountants to the Company to respond to such inquiries as shall be
necessary in connection with such Registration Statement, in the opinion of
Special Counsel and counsel to such underwriters, to conduct a reasonable
investigation within the meaning of the Securities Act. The Company shall not
file any such Registration Statement or related Prospectus or any amendments or
supplements thereto to which the Holders of a majority in aggregate principal
amount of the Transfer Restricted Securities, Special Counsel, or the managing
underwriters, if any, shall reasonably object on a timely basis;

                  (b) Prepare and file with the SEC such amendments, including
post-effective amendments, to each Registration Statement as may be necessary to
keep such Registration Statement continuously effective for the applicable time
period set forth in Section 2(a) hereof; cause the related Prospectus to be
supplemented by any required Prospectus supplement, and as so supplemented to be
filed pursuant to Rule 424 under the Securities Act and the Exchange Act with
respect to the disposition of all securities covered by such Registration
Statement during such period in accordance with the intended method or methods
of disposition by the Holder set forth in such Registration Statement as so
amended or in such Prospectus as so supplemented (including, without limitation,
the filing of any Prospectus supplement pursuant to Rule 424 in order to add or
change any selling security holder 

                                      -9-

<PAGE>   10

information (including any such supplements or amendments pursuant to Section
2(c) hereof, provided such Holder to which such change applies complies with the
Requisite Information requirements of Section 2(c) hereof));

                  (c) Notify the registered (as of the most recent reasonably
practicable date which shall not be more than two Business Days prior to the
date such notice is personally delivered, delivered to a next-day courier,
deposited in the mail or telecopied, as the case may be) Holders, Special
Counsel and the managing underwriters, if any, promptly (and in the case of an
event specified by clause (i)(A) of this paragraph in no event fewer than two
Business Days prior to such filing), and (if requested by any such person),
confirm such notice in writing, (i)(A) when a Prospectus or any Prospectus
supplement or post-effective amendment is proposed to be filed, and, (B) with
respect to a Registration Statement or any post-effective amendment, when the
same has become effective, (ii) of any request of the SEC or any other Federal
or state governmental authority for amendments or supplements to such
Registration Statement or related Prospectus or for additional information
related thereto, (iii) of the issuance by the SEC, any state securities
commission, any other governmental agency or any court of any stop order, order
or injunction suspending or enjoining the use or the effectiveness of the
Registration Statement or the initiation of any proceedings for that purpose,
(iv) if at any time any of the representations and warranties of the Company
contained in any agreement (including any underwriting agreement) contemplated
by Section 4(m) hereof are not true and correct in all material respects, (v) of
the receipt by the Company of any notification with respect to the suspension of
the qualification or exemption from qualification of any of the Transfer
Restricted Securities for sale in any jurisdiction, or the initiation or
threatening of any proceeding for such purpose, and (vi) of the existence of any
fact and the happening of any event that makes any statement made in such
Registration Statement or related Prospectus untrue in any material respect, or
that requires the making of any changes in such Registration Statement or
Prospectus so that in the case of the Registration Statement, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading and that, in the case of the Prospectus, such Prospectus will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading;

                  (d) Use its best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of any stop order or order enjoining or suspending
the use or effectiveness of a Registration Statement or the lifting of any
suspension of the qualification (or exemption from qualification) of any of the
Transfer Restricted Securities for sale in any jurisdiction, at the earliest
practicable moment;

                  (e) If requested by the Special Counsel, the managing
underwriters, if any, or the Holders of a majority in aggregate principal amount
of the Transfer Restricted Securities being sold in connection with such
offering, (i) promptly include in a Prospectus supplement or post-effective
amendment such information as the Special Counsel, the managing underwriters, if
any, and such Holders agree should be included therein, and (ii) make all
required filings of such Prospectus supplement or such post-effective amendment
as soon as reasonably practicable after the Company has received notification of
the matters to be included in such Prospectus supplement or post-effective
amendment; provided, however, that the Company shall not be required to take any
action pursuant to this Section 4(e) that would, in the opinion of counsel for
the Company, violate applicable law or which is not reasonably required to
comply with applicable securities laws;


                                      -10-

<PAGE>   11

                  (f) Furnish to each Holder who so requests, Special Counsel
and each managing underwriter, if any, without charge, at least one conformed
copy of each Registration Statement and each amendment thereto, including
financial statements (but excluding schedules, all documents incorporated or
deemed to be incorporated therein by reference and all exhibits, unless
requested in writing by such Holder, Special Counsel or managing underwriter);

                  (g) Deliver to each Holder, the Special Counsel, and the
underwriters, if any, without charge, as many copies of the Prospectus or
Prospectuses (including each form of Prospectus) and each amendment or
supplement thereto to as such persons may reasonably request; and, unless the
Company shall have given notice to such Holder pursuant to Section 4(c)(vi), the
Company hereby consents to the use of such Prospectus and each amendment or
supplement thereto by each of the selling Holders of Transfer Restricted
Securities and the underwriters, if any, in connection with the offering and
sale of the Transfer Restricted Securities covered by such Prospectus and any
amendment or supplement thereto, provided, however, that no Holder shall be
entitled to use the Prospectus unless and until such Holder shall have furnished
to the Company any and all Requisite Information pursuant to Section 2(c)
hereof;

                  (h) Use its best efforts to register or qualify, or cooperate
with the Holders of Transfer Restricted Securities to be sold or tendered for,
the underwriters, if any, and their respective counsel in connection with the
registration or qualification (or exemption from such registration or
qualification) of, such Transfer Restricted Securities for offer and sale under
the securities or Blue Sky laws of such jurisdictions within the United States
as any Holder or underwriter reasonably requests in writing, keep each such
registration or qualification (or exemption therefrom) effective during the
period such Registration Statement is required to be kept effective and do any
and all other acts or things necessary legally to enable the disposition in such
jurisdictions of the Transfer Restricted Securities covered by the applicable
Registration Statement; provided, however, that the Company shall not be
required to qualify generally to do business in any jurisdiction where it is not
then so qualified, take any action that would subject it to general service of
process in any such jurisdiction where it is not then so subject or subject the
Company to any tax in any such jurisdiction where it is not then so subject;

                  (i) In connection with any sale or transfer of Transfer
Restricted Securities that will result in such securities no longer being
Transfer Restricted Securities, cooperate with the Holders and the managing
underwriters, if any, to (A) facilitate the timely preparation and delivery of
certificates representing Transfer Restricted Securities to be sold, which
certificates shall not bear any restrictive legends, shall bear a CUSIP number
different from the CUSIP number for the Transfer Restricted Securities and shall
be in a form eligible for deposit with The Depository Trust Company and (B)
enable such Transfer Restricted Securities to be in such denominations and
registered in such names as the managing underwriters, if any, or Holders may
reasonably request at least two Business Days prior to any sale of Transfer
Restricted Securities;

                  (j) Use its best efforts to cause the offering of the Transfer
Restricted Securities covered by the Registration Statement to be registered
with or approved by such other governmental agencies or authorities within the
United States, except as may be reasonably required as a consequence of the
nature of a Holder's business, in which case the Company will cooperate in all
reasonable respects with the filing of such Registration Statement and the
granting of such approvals as may be reasonably 

                                      -11-

<PAGE>   12

necessary to enable the seller or sellers thereof or the underwriters, if any,
to consummate the disposition of such Transfer Restricted Securities; provided,
however, that the Company shall not be required to register the Transfer
Restricted Securities in any jurisdiction that would require the Company to
qualify to do business in any jurisdiction where it is not then so qualified,
subject it to general service of process in any such jurisdiction where it is
not then so subject or subject the Company to any tax in any such jurisdiction
where it is not then so subject or to;

                  (k) Upon the occurrence of any event contemplated by Section
4(c)(vi) hereof, as promptly as reasonably practicable, prepare a supplement or
amendment, including, if appropriate, a post-effective amendment, to each
Registration Statement or a supplement to the related Prospectus or any document
incorporated or deemed to be incorporated therein by reference, and file any
other required document so that, as thereafter delivered, such Prospectus will
not contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading;

                  (l) Prior to the effective date of the first Registration
Statement relating to the Transfer Restricted Securities, to provide a CUSIP
number for the Transfer Restricted Securities to be sold pursuant to the
Registration Statement;

                  (m) Enter into such agreements (including an underwriting
agreements in form, scope and substance as are customary in underwritten
offerings) reasonably satisfactory to the Company and take all such other
reasonable actions in connection therewith (including those reasonably requested
by the managing underwriters, if any, or the Holders of a majority in aggregate
principal amount of the Transfer Restricted Securities being sold) in order to
expedite or facilitate the sale of such Transfer Restricted Securities;
provided, however, that the Company is required to facilitate no more than two
underwritten offerings. In such connection, whether or not an underwriting
agreement is entered into and whether or not the registration is an underwritten
registration, (i) make such representations and warranties to the Holders of
such Transfer Restricted Securities and the underwriters, if any, with respect
to the business of the Company and its subsidiaries (including with respect to
businesses or assets acquired or to be acquired by any of them), and the
Registration Statement, Prospectus and documents, if any, incorporated or deemed
to be incorporated by reference therein, in each case, in form, substance and
scope as are customarily made by issuers to underwriters in underwritten
offerings and reasonably acceptable to the Company, and confirm the same if and
when requested; (ii) seek to obtain opinions of counsel to the Company and
updates thereof (which counsel and opinions (in form, scope and substance) shall
be reasonably satisfactory to the managing underwriters, if any, and Special
Counsel to the Holders of the Transfer Restricted Securities being sold,
addressed to each selling Holder of Transfer Restricted Securities and each of
the underwriters, if any, covering the matters customarily covered in opinions
requested in underwritten offerings (including any such matters as may be
reasonably requested by such Special Counsel and underwriters); (iii) use all
reasonable efforts to obtain customary "cold comfort" letters and updates
thereof from the independent certified public accountants of the Company (and,
if necessary, any other independent certified public accountants of any
subsidiary of the Company or of any business acquired by the Company for which
financial statements and financial data is, or is required to be, included in
the Registration Statement), addressed (where reasonably possible) to each
selling Holder of Transfer Restricted Securities and each of the underwriters,
if any, such letters to be in customary form and covering matters of the type
customarily covered in "cold comfort" letters in connection with underwritten
offerings; (iv) if an underwriting agreement is entered into, the same shall


                                      -12-

<PAGE>   13

contain indemnification provisions and procedures no less favorable to the
selling Holders of Transfer Restricted Securities and the underwriters, if any,
than those set forth in Section 6 hereof (or such other provisions and
procedures acceptable to Holders of a majority in aggregate principal amount of
the Transfer Restricted Securities covered by such Registration Statement and
the managing underwriters); and (v) deliver such documents and certificates as
may be reasonably requested by the Holders of majority in aggregate principal
amount of the Transfer Restricted Securities being sold, their Special Counsel
or the managing underwriters, if any, to evidence the continued validity of the
representations and warranties made pursuant to clause (i) of this Section 4(m)
and to evidence compliance with any customary conditions contained in the
underwriting agreement or other agreement entered into by the Company;

                  (n) Make available for inspection by a representative of the
Holders of Transfer Restricted Securities being sold, any underwriter
participating in any such disposition of Transfer Restricted Securities, if any,
and any attorney, consultant or accountant retained by such selling Holders or
underwriter, at the offices where normally kept, during reasonable business
hours, all financial and other records, pertinent corporate documents and
properties of the Company and its subsidiaries as they may reasonably request,
and cause the officers, directors, agents and employees of the Company and its
subsidiaries to supply all information in each case reasonably requested by any
such representative, underwriter, attorney, consultant or accountant in
connection with such Registration Statement, provided, however, that such
persons shall first agree in writing with the Company that any information that
is reasonably and in good faith designated by the Company in writing as

such information is required by court or administrative order or is necessary to

information is required by law (including any disclosure requirements pursuant
to Federal securities laws in connection with the filing of any Registration

failure to safeguard by any such person or (iv) such information becomes

the Transfer Restricted Securities; and in connection therewith, cooperate with
the Trustee and the Holders of Notes constituting Transfer Restricted Securities

Indenture to be so qualified in accordance with the terms of the TIA; and
execute, and use its best efforts to cause the Trustee to execute, all customary
documents as may be required to effect such changes, and all other forms and
documents (including Form T-1) required to be filed with the SEC to enable the
Indenture to be so qualified under the TIA in a timely manner.

                  (p) Comply with applicable rules and regulations of the SEC
and make generally available to its security holders earning statements

(ii) if not sold to underwriters in such an offering, commencing on the first
day of the first 

                                      -13-

<PAGE>   14

fiscal quarter after the effective date of a Registration Statement, which
statement shall cover said period, consistent with the requirements of Rule 158
of the Securities Act; and

                  (q) (i) list all shares of Common Stock covered by such
Registration Statement on any securities exchange on which the Common Stock is
then listed or (ii) authorize for quotation on the National Association of
Securities Dealers Automated Quotation System ("Nasdaq") or the National Market
of Nasdaq all Common Stock covered by such Registration Statement if the Common
Stock is then so authorized for quotation.

         5.       Registration Expenses

                  (a) All fees and expenses incident to the performance of or
compliance with this Agreement by the Company shall be borne by it whether or

Section 4(m)(iii) (including, without limitation, the expenses of any special

and (vii) fees and expenses of all other persons retained by the Company. In

shall pay all underwriting discounts and brokerage commissions with respect to
any Transfer Restricted Securities sold by it.

                  (b) In connection with any registration hereunder, the Company
shall reimburse the Holders of the Transfer Restricted Securities being
registered or tendered for in such registration for the reasonable fees and
disbursements of not more than one firm of attorneys representing the selling
Holders, which firm shall initially be Wilson Sonsini Goodrich & Rosati,
Professional Corporation, but which may, with the written consent of the Initial
Purchasers (which shall not be unreasonably withheld), 

                                      -14-

<PAGE>   15

be another nationally recognized law firm experienced in securities law matters
designated by the Company unless and until another Special Counsel shall have
been selected by a majority in aggregate principal amount of the Transfer
Restricted Securities and notice hereof shall have been given to the Company.

         6.       Indemnification

                  (a) The Company agrees to indemnify and hold harmless (i) the
Purchasers, (ii) each Holder, (iii) each person, if any, who controls (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) any of the foregoing (any of the persons referred to in this clause (iii)
being hereinafter referred to as a "controlling person"), and (iv) the
respective officers, directors, partners, employees, representatives and agents
of the Purchasers, the Holders (including predecessor Holders), or any
controlling person (any person referred to in clause (i), (ii), (iii) or (iv)
may hereinafter be referred to as an "Indemnified Person"), from and against any
and all losses, claims, damages, liabilities, expenses and judgments caused by
any untrue statement or alleged untrue statement of a material fact contained in
any Registration Statement or Prospectus or in any amendment or supplement
thereto or in any preliminary Prospectus, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or
supplement thereto, in light of the circumstances under which they were made)
not misleading, except insofar as such losses, claims, damages, liabilities,
expenses or judgments are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information relating to any
Indemnified Person furnished to the Company by or on behalf of such Indemnified
Person expressly for use therein; provided, however, that the foregoing
indemnity with respect to any preliminary Prospectus shall not inure to the
benefit of any Indemnified Person from whom the person asserting such losses,
claims, damages, liabilities, expenses and judgments purchased securities if
such untrue statement or omission or alleged untrue statement or omission made
in such preliminary Prospectus is eliminated or remedied in the Prospectus and a
copy of the Prospectus shall not have been furnished to such person in a timely
manner due to the wrongful action or wrongful inaction of such Indemnified
Person, whether as a result of negligence or otherwise.

                  (b) In case any action shall be brought against any
Indemnified Person, based upon any Registration Statement or any such Prospectus
or any amendment or supplement thereto and with respect to which indemnity may
be sought against the Company, such Indemnified Person shall promptly notify the
Company in writing and the Company shall assume the defense thereof, including
the employment of counsel reasonably satisfactory to such Indemnified Person and
payment of all fees and expenses. Any Indemnified Person shall have the right to
employ separate counsel in any such action and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Person, unless (i) the employment of such counsel shall have
been specifically authorized in writing by the Company, (ii) the Company shall
have failed to assume the defense and employ counsel or (iii) such Indemnified
Person or Persons shall have been advised by counsel that there may be a
conflict between the positions of the indemnifying party or parties and of the
indemnified party or parties in conducting the defense of such action or
proceeding or that there may be legal defenses available to such Indemnified
Person or Persons different from or in addition to those available to the
indemnifying party or parties (in which case the Company shall not have the
right to assume the defense of such action on behalf of such Indemnified Person,
it being understood, however, that the Company shall not, in connection with any
one such action or separate but substantially similar or related actions in 


                                      -15-

<PAGE>   16

the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the fees and expenses of more than one separate
firm of attorneys (in addition to any local counsel) for all such Indemnified
Persons, which firm shall be designated in writing by such Indemnified Persons,
and that all such fees and expenses shall be reimbursed as they are incurred).
The Company shall not be liable for any settlement of any such action effected
without its written consent but if settled with the written consent of the
Company, the Company agrees to indemnify and hold harmless any Indemnified
Person from and against any loss or liability by reason of such settlement. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in respect
of which any indemnified party is or could have been a party and indemnity could
have been sought hereunder by such indemnified party, unless such settlement
includes an unconditional release of such indemnified party from all liability
on claims that are the subject matter of such proceeding.

                  (c) In connection with any Registration Statement pursuant to
which any Holder (or predecessor Holder) sold or offered for resale Transfer
Restricted Securities, such Holder (or predecessor Holder) agrees, severally and
not jointly, to indemnify and hold harmless the Company, its directors, its
officers and any person controlling the Company within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act, to the same extent as
the foregoing indemnity from the Company to each Indemnified Person but only
with reference to information relating to such Indemnified Person furnished by
or on behalf of such Indemnified Person expressly for use in such Registration
Statement. In case any action shall be brought against the Company, any of its
directors, any such officer or any person controlling the Company based on such
Registration Statement and in respect of which indemnity may be sought against
any Indemnified Person, the Indemnified Person shall have the rights and duties
given to the Company (except that if the Company shall have assumed the defense
thereof, such Indemnified Person shall not be required to do so, but may employ
separate counsel therein and participate in defense thereof but the fees and
expenses of such counsel shall be at the expense of such Indemnified Person),
and the Company, its directors, any such officers and any person controlling the
Company shall have the rights and duties given to the Indemnified Person by
Section 6(b) hereof.

                  (d) If the indemnification provided for in this Section 6 is
unavailable to an indemnified party in respect of any losses, claims, damages,
liabilities, expenses or judgments referred to therein, then each indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities, expenses and judgments (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and each Indemnified Person on the other hand pursuant tot he Purchase
Agreement or from the offering for resale of the Transfer Restricted Securities
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company and each such Indemnified Person in connection with the statements
or omissions which resulted in such losses, claims, damages, liabilities,
expenses or judgments, as well as any other relevant equitable considerations.
The relative fault of the Company and each such Indemnified Person shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the Company or such Indemnified Person and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

                                      -16-

<PAGE>   17


                  The Company, the Holders and the Purchasers agree that it
would not be just and equitable if contribution pursuant to this Section 6(d)
were determined by pro rata allocation (even if the Indemnified Person were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to in the
immediately preceding paragraph. The amount paid or payable by an indemnified
party as a result of the losses, claims, damages, liabilities, expenses or
judgments referred to in the immediately preceding paragraph shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 6, no Indemnified Person shall be required to contribute any amount in
excess of the amount by which the total net profit received by it in connection
with the sale of the Transfer Restricted Securities pursuant to this Agreement
exceeds the amount of any damages which such Indemnified Person has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Indemnified Persons' obligations to contribute pursuant
to this Section 6(d) are several in proportion to the respective amount of
Transfer Restricted Securities included in and sold pursuant to any such
Registration Statement by each Indemnified Person and not joint.

         7.       Rules 144 and 144A

                  The Company shall to file the reports required to be filed by
it under the Securities Act and the Exchange Act in a timely manner and, if at
any time it is not required to file such reports but in the past had been
required to or did file such reports, it will, upon the request of any Holder,
make available other information as required by, and so long as necessary to
permit sales of, its Transfer Restricted Securities pursuant to Rule 144 and
Rule 144A. Notwithstanding the foregoing, nothing in this Section 7 shall be
deemed to require the Company to register any of its securities pursuant to the
Exchange Act.

         8.       Underwritten Registrations

                  If any of the Transfer Restricted Securities covered by any
Shelf Registration Statement are to be sold in an underwritten offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be investment bankers of recognized national
standing selected by the Holders of a majority in aggregate principal amount of
such Transfer Restricted Securities included in such offering, subject to the
consent of the Company (which will not be unreasonably withheld or delayed).

                  No person may participate in any underwritten registration
hereunder unless such person (i) agrees to sell such person's Transfer
Restricted Securities on the basis reasonably provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities underwriting agreements, lock-up agreements and other
documents reasonably required under the terms of such underwriting arrangements.

<PAGE>   18

         9.       Miscellaneous

                  (a) Remedies. In the event of a breach by the Company or by a
Holder of any of their respective obligations under this Agreement, each Holder
or the Company, in addition to being entitled to exercise all rights granted by
law, including, without limitation, recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each
Holder agree that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agree that, in the event of any action for specific
performance in respect of such breach, they shall waive the defense that a
remedy at law would be adequate. This Section 9(a) shall not apply to Section 3.

                  (b) No Inconsistent Agreements. The Company shall not enter
into any agreement with respect to its securities that is inconsistent with the
rights granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. The Company is not currently a party to any agreement
granting any registration rights with respect to any of its securities to any
person which conflicts with the Company's obligations hereunder or gives any
other party the right to include any securities in any Registration Statement
filed pursuant hereto, except for such rights and conflicts as have been
irrevocably waived. Without limiting the generality of the foregoing, without
the written consent of the Holders of a majority in aggregate principal amount
of the Transfer Restricted Securities, the Company shall not grant to any person
the right to request it to register any of its securities under the Securities
Act unless the rights so granted are subject in all respect to the prior rights
of the Holders set forth herein, and are not otherwise in conflict or
inconsistent with the provisions of this Agreement.

                  (c) No Adverse Action Affecting the Transfer Restricted
Securities. The Company will not take any action with respect to the Transfer
Restricted Securities which would adversely affect the ability of any of the
Holders to include such Transfer Restricted Securities in a registration
undertaken pursuant to this Agreement.

                  (d) No Piggyback on Registrations. After the date hereof, the
Company shall not grant to any of its security holders (other than the Holders
in such capacity) the right to include any of its securities in any Shelf
Registration Statement.

                  (e) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof,
may not be given, without the written consent of the Holders of a majority in
aggregate principal amount of the Transfer Restricted Securities; provided,
however, that, for the purposes of this Agreement, Transfer Restricted
Securities that are owned, directly or indirectly, by either the Company or an
Affiliate of the Company are not deemed outstanding. Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with respect
to a matter that relates exclusively to the rights of Holders whose Transfer
Restricted Securities are being sold pursuant to an underwritten offering and
that does not directly or indirectly affect the rights of other Holders may be
given by Holders of a majority in aggregate principal amount of the Transfer
Restricted Securities being sold by such Holders pursuant to such an
underwritten offering; provided, however, that the provisions of this sentence
may not be amended, modified, or supplemented except in accordance with the
provisions of the immediately preceding sentence.

                                                   May 20, 1999

SportsLine USA, Inc.
6340 N.W. 5th Way
Fort Lauderdale, Florida 33309

Ladies and Gentlemen:

         We have acted as counsel to SportsLine USA, Inc., a Delaware
corporation (the "Company"), in connection with the registration under the
Securities Act of 1933, as amended, of $150,000,000 aggregate principal amount
of 5% Convertible Subordinated Notes due 2006 (the "Notes") issued by the
Company and such indeterminate number of shares of the Company's Common Stock,
$0.01 par value per share, issuable upon conversion thereof (the "Shares," and
together with the Notes, the "Offered Securities"), each as described in the
Company's Registration Statement on Form S-3 (the "Registration Statement")
filed with the Securities and Exchange Commission on or about the date hereof
with respect to the resale of the Offered Securities by the holders thereof.

         In rendering this opinion, we have examined and relied upon such
documents and records of the Company and other documents as we have deemed
necessary for the expression of opinions herein contained. In making the
foregoing examinations, we have assumed the genuineness of all signatures and
the authenticity of all documents submitted to us as originals, and the
conformity to original documents of all documents submitted to us as certified
or photostatic copies. As to various questions of fact material to this opinion,
we have relied, to the extent we deem reasonably appropriate, upon
representations or certificates of officers or directors of the Company and upon
documents, records and instruments furnished to us by the Company, without
independently checking or verifying the accuracy of such documents, records and
instruments.

         Based upon the foregoing examination, we are of the opinion that (i)
the Notes have been duly and validly authorized and issued and, assuming due
authorization by the trustee for the Notes, constitute the legal and binding
obligations of the Company entitled to the benefits provided by the Indenture
(the "Indenture"), dated as of March 15, 1999, between the Company and State
Street Bank and Trust Company, as trustee, subject to applicable bankruptcy and
insolvency laws and the application of general principles of equity, and (ii)
the Shares have been duly and validly authorized, and when issued upon the due
conversion of the Notes in accordance with their terms and the Indenture, will
be validly issued, fully paid and nonassessable.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the caption "Legal
Matters" in the Prospectus forming a part of the Registration Statement. In
giving such consent, we do not admit that we come within the category of persons
whose consent is required by Section 7 of the Act or the rules and regulations
of the Commission thereunder.

                                     Sincerely,

                                     /s/ Greenberg Traurig, P.A.
