                          PURPOSE OF THE TENDER OFFER

     The purpose of the Tender Offer is to enable the Company to eliminate or
reduce the debt evidenced by the Notes at a substantial discount. All of the
Notes purchased by the Company upon the consummation of the Tender Offer will be
retired by the Company. Assuming all of the outstanding Notes are tendered to
and purchased by the Company pursuant to the Tender Offer, upon such retirement,
the Company's total
                                        5
<PAGE>   6

indebtedness will be reduced from approximately $90.2 million to $0.2. In August
1999, the Company repurchased $60.0 million in principal amounts of Notes. These
repurchases occurred in unsolicited open market transactions with persons who
were not affiliates of the Company for an aggregate purchase price of
approximately $36.4 million.

     The Tender Offer also gives Holders who are considering the sale of all or
some of their Notes the opportunity to sell their Notes for a higher price than
may have been available in the open market immediately prior to the announcement
of the Tender Offer and without the usual transaction costs associated with
market sales. There may be adverse consequences to holder of Notes who do not
tender them in the Tender Offer. See "Certain Considerations Relating to the
Tender Offer."

     Under the terms of the Tender Offer, Notes acquired by the Company will be
purchased by the Company at a substantial discount to their stated principal
amount. Accordingly, if the Company acquires all $90.0 million principal amount
of the Notes currently outstanding, the Company will recognize an extraordinary
gain, after giving effect to unamortized debt issuance costs and transaction
costs, of approximately $18.7 million in addition to the extraordinary gain of
approximately $22.5 million the Company recognized on the repurchases of $60.0
million principal amount Notes in August 1999. Such extraordinary gain
represents the excess of the stated principal amount of the Notes over their
respective purchase prices. As of June 30, 1999, the Company had, for income tax
purposes, an accumulated net operating loss carryforward of approximately $108.0
million. If the Company has taxable income before applying net operating losses,
the Company may have a current regular tax liability due to the limitation on
the use of the net operating losses under the change of ownership rules. The
Company could also be subject to the alternative minimum tax due to the
limitation on the use of the net operating losses. Transaction costs with
respect to the Tender Offer, including fees to be paid to the Dealer Manager,
are expected to be approximately $1.1 million, and the Company expects to use
cash on hand and cash generated by the sale of short-term investments or other
cash-equivalents to purchase the Notes in the Tender Offer and to pay such
expenses. Any Notes purchased pursuant to the Tender Offer will be retired by
the Company.

                             tender Notes should contact promptly such
                             registered Holder. A beneficial owner of Notes that
                             are held of record by a custodian bank, depositary,
                             broker, trust company or other nominee must
                             instruct such entity to tender the Notes on the
                             beneficial owner's behalf. An Instruction Form is
                             included in the Tender Offer materials provided
                             along with this Offer to Purchase, which may be
                             used by a beneficial owner to give such
                             instructions to its nominee. See "The Tender
                             Offer -- Procedures for Tendering Notes -- Proper
                             Tender of Notes" and the Letter of Transmittal.

Certain Consequences Of Not
  Tendering................  The trading market for Notes not tendered in
                             response to the Tender Offer is likely to be very
                             limited, due to the reduction in the amount of
                             Notes outstanding. In addition, there can be no
                             assurance that the Company will have sufficient
                             cash available upon the maturity of the Notes to
                             repay the principal and accrued interest of the
                             Notes outstanding on such date. See "Certain
                             Considerations Relating to the Tender
                             Offer -- Diminished Market and Trading of the
                             Notes" and "Market and Trading Information."

Brokerage Commission.......  No brokerage commissions are payable by Holders to
                             the Dealer Manager, the Information Agent, the
                             Company or the Depositary.

Dealer Manager.............  The Company has retained BancBoston Robertson
                             Stephens Inc. to act as the Dealer Manager in
                             connection with the Tender Offer. In its capacity
                             as the Dealer Manager, BancBoston Robertson
                             Stephens Inc. may contact Holders regarding the
                             Tender Offer and may request brokers, dealers and
                             other nominees to forward this Offer to Purchase
                             and related materials to beneficial owners of
                             Notes.

Depositary.................  The Depositary for the Tender Offer is State Street
                             Bank and Trust Company.

Information Agent..........  The Information Agent for the Tender Offer is
                             Morrow & Co., Inc. Questions, requests for
                             assistance and requests for additional copies of
                             the Offer to Purchase or the Letter of Transmittal
                             and requests for Notices of Guaranteed Delivery
                             should be directed to the Information Agent.

              CERTAIN CONSIDERATIONS RELATING TO THE TENDER OFFER

     In deciding whether to participate in the Tender Offer, each Holder should
consider carefully, in addition to the other information contained or
incorporated by reference herein, the information appearing in the Company's
Annual Report on Form 10-K for the year ended December 31, 1998 under the
caption "Risk Factors that May Affect Future Results" in "Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations," which
information is incorporated herein by reference. Each such Holder should also
consider the following factors when making a decision about whether or not to
tender Notes in the Tender Offer:

     Diminished Market and Trading of the Notes.  The Notes are currently traded
over-the-counter, and trading in the Notes has been limited. Although the
Company expects Notes that are not tendered may continue to be traded, to the
extent that Notes are tendered and accepted for payment in the Tender Offer, the
trading market for Notes that remain outstanding will be very limited, which may
adversely affect the liquidity of the Notes. An issue of securities with a
smaller float may trade at lower prices than would a comparable issue of
securities with a greater float. Accordingly, the market price for Notes that
are not tendered in the Tender Offer may be adversely affected to the extent
that the amount of the Notes purchased pursuant to the Tender Offer reduces the
float. The reduced float may also have the effect of causing the trading prices
of the Notes that are not tendered or purchased to be more volatile. As a
result, there can be no assurance that there will be an active trading market
for the Notes after consummation of the Tender Offer.

     History of Losses; Repayment of Notes Uncertain.  The Company has
experienced significant operating losses in each period since inception and, as
of June 30, 1999, had an accumulated deficit of $114.9 million. Accordingly,
there can be no assurance that the Company will achieve profitability at a level
sufficient to assure repayment of Notes that remain outstanding following the
Tender Offer. In addition, the Indenture imposes no significant restrictions on
the Company's ability to spend its available cash or other resources, including
long-term investments in product lines or other businesses that may not produce
returns on the Company's investment over the near term. The Indenture also
imposes no restrictions on the Company's ability to incur Senior Indebtedness to
which the Notes will be subordinate. The incurrence by the Company of any such
Senior Indebtedness may have the result of making repayment of the Notes upon
maturity less probable. Accordingly, there can be no assurance that the Company
will have sufficient cash on hand or available from the liquidation of other
assets, or that other sources of funding will be available, to pay interest on
the Notes prior to maturity, or principal and accrued interest on the Notes at
maturity.

                                   THE NOTES

     The following summary of certain terms of the Notes does not purport to be
complete and is qualified in its entirety by reference to the Indenture.

The Notes..................  $90.0 million outstanding aggregate principal
                             amount of 5% Convertible Subordinated Notes due
                             2006.

Interest...................  Interest on the Notes is payable semi-annually on
                             April 1 and October 1 of each year.

Maturity...................  April 1, 2006.

Conversion.................  Convertible at the holder's option into Common
                             Stock at any time through the close of business on
                             the final maturity date of the Notes, unless
                             previously redeemed or repurchased, at an initial
                             conversion rate of 15.355 shares of Common Stock
                             per $1,000 principal amount of Notes (equivalent to
                             a conversion price of approximately $65.125 per
                             share).

Optional Redemption........  The Notes are not redeemable at the option of the
                             Company prior to April 2, 2002. Thereafter, the
                             Notes are redeemable on at least 30 days' notice at
                             the option of the Company, in whole or in part at
                             any time at the redemption prices set forth in the
                             Indenture.

Repurchase at Option of
Holders Upon a Repurchase
  Event....................  In the event that a Repurchase Event (as defined in
                             the Indenture) occurs, each holder of Notes may
                             require the Company to repurchase all or a portion
                             of such Notes for cash or, at the Company's option,
                             Common Stock (valued at 95% of the average of the
                             closing prices for the five trading days
                             immediately preceding and including the third
                             trading day prior to the repurchase date) at a
                             repurchase price of 100% of the principal amount of
                             the Notes to be repurchased, plus accrued and
                             unpaid interest to the repurchase date.

Ranking....................  The Notes are subordinate to all existing and
                             future Senior Indebtedness (as defined in the
                             Indenture) of the Company and effectively
                             subordinated to all liabilities, including trade
                             payables, of the Company's subsidiaries. As of June
                             30, 1999, the Company had no material indebtedness
                             outstanding that would have constituted Senior
                             Indebtedness. The Indenture contains no limitations
                             on the incurrence of additional Senior Indebtedness
                             or other indebtedness by the Company or any
                             subsidiary.

                         MARKET AND TRADING INFORMATION

     The Notes are currently traded over-the-counter basis. There is no
established reporting system for trading in the Notes. Therefore, the Company is
unable to determine the trading history of the Notes. However, the Company
believes that trading in the Notes has been limited and sporadic. Although the
Company expects any untendered Notes may continue to be traded after the
consummation of the Tender Offer, to the extent that the Notes are traded, the
prices of Notes may fluctuate greatly depending on the trading volume and the
balance between buy and sell orders. The Company believes that the trading
market for the Notes that remain outstanding after the Tender Offer will be very
limited. See "Certain Considerations Relating to the Tender Offer -- Diminished
Market and Trading of the Notes."

     In August 1999, the Company repurchased $60.0 million in principal amount
of Notes. These repurchases occurred in unsolicited open market transactions
with persons who were not affiliates of the Company for an aggregate purchase
price of approximately $36.4 million.

     The Common Stock is currently traded on the Nasdaq National Market. On
September 20, 1999, the last reported sale price of the Common Stock on the
Nasdaq National Market was $25.38 per share.

     The following table sets forth certain information relating to the trading
history of the Common Stock on the Nasdaq National Market during the period from
March 24, 1999 (the original issue date of the Notes) through September 20,
1999.

     The Company and its affiliates, including its executive officers and
directors, will be prohibited under applicable Federal securities laws from
repurchasing additional Notes outside of the Tender Offer until at least the
tenth business day after the Expiration Date. Following such time, if any Notes
remain outstanding after the completion of the Tender Offer, the Company may
purchase additional Notes in the open market, in private transactions, through a
subsequent tender offer, or otherwise, any of which may be consummated at
purchase prices higher or lower than that offered in the Tender Offer. The
decision to repurchase additional Notes, if any, will depend upon many factors,
including the market price of the Notes, the results of the Tender Offer, the
Company's business and financial position and general economic and market
conditions. Any such repurchase may be on the same terms or on terms more or
less favorable to Holders than the terms of the Tender Offer.

as of June 30, 1999, and as adjusted to give effect to the Tender Offer,

                                THE TENDER OFFER

PRINCIPAL TERMS OF THE TENDER OFFER

     Upon the terms and subject to the conditions set forth in this Offer to
Purchase and in the accompanying Letter of Transmittal, the Company is offering
to purchase any and all outstanding Notes for a cash purchase price of $750 per
$1,000 principal amount plus accrued and unpaid interest from October 1, 1999 up
to, but not including, the date of payment (the "Payment Date").

EXPIRATION DATE; EXTENSION; TERMINATION; AMENDMENTS

     The Tender Offer will expire on the Expiration Date. The Company expressly
reserves the right to extend the Tender Offer on a daily basis or for such
period or periods as it may determine in its sole discretion from time to time
by giving written or oral notice to the Depositary and by making a public
disclosure prior to 9:00 a.m., New York City time, on the next business day
following the previously scheduled Expiration Date. During any extension of the
Tender Offer, all Notes previously tendered and not accepted for purchase will
remain subject to the Tender Offer and may, subject to the terms and conditions
of the Tender Offer, be accepted for purchase by the Company.

     The Company expressly reserves the absolute right, in its sole discretion,
to (i) waive any condition to the Tender Offer, (ii) amend any terms of the
Tender Offer, subject to the Holders' withdrawal rights, or (iii) modify the
Tender Offer. Any waiver or amendment applicable to the Tender Offer will apply
to all Notes tendered regardless of when or in what order such Notes were
tendered. If the Company makes a material change in the terms of the Tender
Offer or if it waives a material condition of the Tender Offer, the Company will
extend the Tender Offer. The minimum period for which the Tender Offer will be
extended following a material change or waiver, other than a change in the
amount of the Notes being sought for tender or in the consideration offered,
will depend upon the facts and circumstances, including the relative materiality
of the change or waiver. With respect to a change in the amount of the Notes
being sought or in the consideration offered, the Tender Offer will be extended
for a minimum of ten business days following public announcement of such change.
If the Company amends the terms of the Tender Offer, such amendment will apply
to all Notes tendered pursuant thereto regardless of when or in what order such
Notes were tendered.

     The Company expressly reserves the right, in its sole discretion, to
terminate the Tender Offer if any of the conditions applicable thereto set forth
under "-- Conditions of the Tender Offer" exist and has not been waived by the
Company. Any such termination will be followed promptly by public announcement
thereof. In the event the Company terminates the Tender Offer, it will give
immediate notice thereof to the Depositary, and all Notes theretofore tendered
pursuant to the Tender Offer will be returned promptly to the tendering Holders
thereof. See "-- Withdrawal of Tenders" and "-- Conditions of the Tender Offer."

     Any extension, waiver of a condition, delay, termination or amendment of
the Tender Offer will be disseminated by such means that the Company deems
appropriate, which may include dissemination by press release. Any such
dissemination, if not in the form of a press release, will be followed as
promptly as practicable by a press release or other public announcement thereof,
such announcement in the case of an extension to be issued no later than 9:00
a.m., New York City time, on the next business day after the previously
scheduled Expiration Date. Without limiting the manner by which the Company may
choose to make such announcement, the Company will not, unless otherwise
required by law, have any obligation to publish, advertise or otherwise
communicate any such announcement.

ACCEPTANCE OF NOTES FOR PURCHASE; PAYMENT FOR NOTES

     Upon the terms and subject to the conditions of the Tender Offer, promptly
after the Expiration Date, the Company will, subject to the satisfaction or
waiver of all relevant conditions, accept for purchase, and pay for, all Notes
validly tendered and not withdrawn under the Tender Offer on or prior to the
Expiration Date.

     The Company expressly reserves the right, in its sole discretion, to delay
acceptance for purchase of Notes tendered under the Tender Offer or the payment
for Notes accepted for purchase (subject to

                                       13
<PAGE>   14

Rule 14e-1(c) under the Exchange Act, which requires that the Company pay the
consideration offered or return the Notes deposited by or on behalf of the
Holders promptly after the termination or withdrawal of the Tender Offer), or to
terminate the Tender Offer and not accept for purchase any Notes not theretofore
accepted for purchase, if any of the conditions set forth under "-- Conditions
of the Tender Offer" shall not have been satisfied or waived by the Company or
in order to comply in whole or in part with any applicable law. In all cases,
payment for Notes purchased pursuant to the Tender Offer will be made only after
timely receipt by the Depositary of (i) such Notes, or timely confirmation of a
book-entry transfer (a "Book-Entry Confirmation") of such Notes into the
Depositary's account at DTC pursuant to the procedures set forth below in
"Procedures for Tendering Notes," (ii) a properly completed and duly executed
Letter of Transmittal (or an Agent's Message in lieu thereof) and (iii) all
necessary signature guarantees and any other documents required by the Letter of
Transmittal. See "-- Procedures for Tendering Notes" for a description of the
procedures for tendering Notes pursuant to the Tender Offer.

     For purposes of the Tender Offer, the Company will be deemed to have
accepted for payment (and therefore purchased) Notes when and if it gives oral,
to be followed by written, notice to the Depositary of its acceptance of such
Notes for payment pursuant to the Tender Offer. Payment for Notes purchased
pursuant to the Tender Offer will be made by the Company on the Payment Date by
depositing the Tender Offer Consideration therefor with the Depositary, which
will act as agent for tendering Holders for the purpose of receiving Tender
Offer Consideration from the Company and transmitting Tender Offer Consideration
to the tendering Holders.

     Tenders with respect to the Notes pursuant to the Tender Offer will be
accepted only in principal amounts equal to $1,000 or integral multiples
thereof.

     The Company does not expect to increase or decrease the consideration
offered in the Tender Offer, but if the consideration offered in the Tender
Offer is increased, all tendering Holders whose Notes are accepted for payment
pursuant to the Tender Offer will be given the increased consideration
regardless of when or in what order such Notes were tendered.

     Under no circumstances will any interest be payable because of any delay in
the transmission of funds to the Holders of purchased Notes. If any tendered
Notes are not accepted for payment for any reason pursuant to the terms and
conditions of the Tender Offer or if certificates are submitted evidencing more
Notes than are tendered, certificates evidencing unpurchased Notes will be
returned, without expense, to the tendering Holder (or, in the case of Notes
tendered by book-entry transfer into the Depositary's account at DTC, the
account maintained at DTC designated by the participant therein who so delivered
such Notes), unless otherwise requested by such Holder under "Special Delivery
Instructions" in the Letter of Transmittal, promptly following the Expiration
Date or the termination of the Tender Offer.

     The Company intends to conduct the Tender Offer in accordance with the
applicable requirements of the Exchange Act and the rules and regulations of the
Commission thereunder.

     Tendering Holders whose Notes are purchased in the Tender Offer will not be
obligated to pay brokerage commissions or fees or to pay transfer taxes with
respect to the purchase of their Notes unless the box entitled "Special Payment
Instructions" or the box entitled "Special Delivery Instructions" in the
respective Letter of Transmittal has been completed, as described in the
instructions thereto. The Company will pay all other charges and expenses in
connection with the Tender Offer. See "-- Depositary" and "-- Miscellaneous."

PROCEDURES FOR TENDERING NOTES

     Proper Tender of Notes.  For Notes to be properly tendered pursuant to the
Tender Offer, (i) such Notes, in physical certificated form, together with a
properly completed and duly executed Letter of Transmittal (or manually signed
facsimile thereof), and any other documents required by the Letter of
Transmittal, must be received on or prior to the Expiration Date by the
Depositary at one of the addresses set forth on the back cover of this Offer to
Purchase, or (ii) such Notes, in book-entry form, must be tendered pursuant to
the procedure for book-entry transfer described below under the caption
"Book-Entry Delivery" and a Book-Entry Confirmation, including an Agent's
Message, must be received by the Depositary, in each

                                       14
<PAGE>   15

case on or prior to the Expiration Date, or (iii) the tendering Holder must
comply with the guaranteed delivery procedures described below under the caption
"Guaranteed Delivery." Holders whose Notes are registered in the name of a
nominee are urged to contact such nominee promptly if they wish to accept the
Tender Offer. A beneficial owner of Notes that are held of record by a custodian
bank, depositary, broker, trust company or other nominee must instruct such
entity to tender the Notes on the beneficial owner's behalf. An Instruction Form
is included in the Tender Offer materials provided along with this Offer to
Purchase, which may be used by a beneficial owner to give such instructions to
its nominee. LETTERS OF TRANSMITTAL SHOULD BE SENT ONLY TO THE DEPOSITARY, AND
NOT TO THE COMPANY, THE TRUSTEE, THE INFORMATION AGENT OR THE DEALER MANAGER.

     Except as provided below under the captions "Book-Entry Delivery" and
"Guaranteed Delivery," unless the Notes being tendered are deposited with the
Depositary on or prior to the Expiration Date (accompanied by a properly
completed and duly executed Letter of Transmittal and any other documents
required by the Letter of Transmittal), the Company may, at its option, reject
such tender. If less than the entire principal amount of any Notes evidenced by
a submitted certificate(s) is to be tendered, the tendering Holder should fill
in the principal amount tendered in the appropriate box on the Letter of
Transmittal. The entire principal amount represented by all Notes deposited with
the Depositary will be deemed to have been tendered unless otherwise indicated.

     In all cases, notwithstanding any provision hereof, the payment for Notes
tendered and accepted for payment pursuant to the Tender Offer will be made only
after the timely receipt by the Depositary of (i) certificates for such Notes or
a timely Book-Entry Confirmation, (ii) the Letter of Transmittal (or a manually
signed facsimile thereof) properly completed and duly executed, or an Agent's
Message, and (iii) any required signature guarantees or other documents required
by such Letter of Transmittal.

     Method of Delivery.  ALL LETTERS OF TRANSMITTAL, NOTICES OF GUARANTEED
DELIVERY AND NOTES SHOULD BE DELIVERED ONLY BY COURIER, HAND DELIVERY OF
TRANSMITTED BY MAIL. DELIVERIES SHOULD BE MADE ONLY TO THE DEPOSITARY, AND NOT
TO THE COMPANY, THE TRUSTEE, THE INFORMATION AGENT OR THE DEALER MANAGER. THE
METHOD OF DELIVERY OF CERTIFICATES FOR NOTES AND ALL OTHER REQUIRED DOCUMENTS IS
AT THE OPTION AND RISK OF THE TENDERING HOLDER, AND DELIVERY WILL BE DEEMED TO
BE MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF CERTIFICATES OF NOTES
ARE SENT BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED.

     Signature Guarantees.  No signature guarantees are required on the Letter
of Transmittal if the Letter of Transmittal is signed by the registered holder
of the Notes tendered herewith and payment is to be made directly to such
registered holder, or if Notes are tendered for the account of an institution
that is a member of a Signature Guarantee Program recognized by the Depositary
(i.e., the Securities Transfer Agent Medallion Program (STAMP), the Stock
Exchanges Medallion Program (SEMP) and the New York Stock Exchange Medallion
Program (MSP)) (each such entity being hereinafter referred to an as "Eligible
Institution"). In all other cases, all signatures on the Letter of Transmittal
must be guaranteed by an Eligible Institution. See Instruction 3 of the Letter
of Transmittal. If a Note is registered in the name of a person other than the
person signing a Letter of Transmittal, or if payment is to be made or Notes not
purchased or tendered are to be issued, to a person other than the registered
holder, then such Notes must be endorsed or accompanied by a written instrument
or instruments of transfer in a form satisfactory to the Company, in either
case, executed by the registered holder with the signature guarantees by an
Eligible Institution.

     Book-Entry Delivery.  The Depositary will establish an account or accounts
with respect to the Notes at DTC for purposes of the Tender Offer within two
business days after the date of the commencement of the Tender Offer, and any
financial institution that is a participant in DTC's system may make book-entry
delivery of the Notes by causing DTC to transfer such Notes into the
Depositary's account at DTC in accordance with DTC's procedure for such
transfer. With respect to tenders of Notes effected through book-entry transfer
at DTC, an Agent's Message, in lieu of a completed and duly executed Letter of
Transmittal, must be transmitted to and received by the Depositary on or prior
to the Expiration Date, or the Holder must comply with the guaranteed delivery
procedures described below.

                                       15
<PAGE>   16

     The term "Agent's Message" means a message transmitted by DTC and received
by the Depositary and forming a part of a Book-Entry Confirmation that states
that DTC has received an express acknowledgment from a participant in DTC
tendering the Notes that such participant has received the Letter of Transmittal
and agrees to be bound by the terms of the Letter of Transmittal (or, in the
case of an Agent's Message relating to a guaranteed delivery, that such
participant has received and agrees to be bound by the Applicable Notice of
Guaranteed Delivery) and the Company may enforce such agreement against such
participant.

     Guaranteed Delivery.  If a Holder desires to tender Notes pursuant to the
Tender Offer and such Holder's certificates are not immediately available or
time will not permit all required documents to reach the Depositary on or prior
to the Expiration Date, or such Holder cannot complete the procedures for
book-entry transfer on a timely basis, such Notes may nevertheless be tendered
provided that all of the following conditions are satisfied:

          (a) The tender is made by or through an Eligible Institution;

          (b) On or prior to the Expiration Date, the Depositary receives from
     such Eligible Institution at one of the addresses for the Depositary set
     forth on the back cover of this Offer to Purchase, a properly completed and
     duly executed Notice of Guaranteed Delivery (by mail, hand delivery or
     facsimile). Such Notice of Guaranteed Delivery shall (i) be substantially
     in the form made available by the Company, (ii) set forth the name and
     address of the Holder, (iii) describe the Notes and the principal amount of
     the Notes tendered, (iv) state that the tender is being made thereby and
     (v) guarantee that, within three New York Stock Exchange trading days after
     the date of execution of such Notice of Guaranteed Delivery, a duly
     executed Letter of Transmittal (or a manually signed facsimile thereof) or
     an Agent's Message together with the certificates representing such Notes
     (or appropriate Book-Entry Confirmation) and any other documents required
     by the Letter of Transmittal and the instructions thereto will be deposited
     by the Eligible Institution with the Depositary; and

          (c) The certificates for the tendered Notes in proper form for
     transfer (or confirmation of book-entry transfer into the Depositary's
     account at DTC), together with a properly completed and duly executed
     Letter of Transmittal (or a manually signed facsimile thereof), or
     confirmation of a book-entry transfer of such Notes into the Depositary's
     account with DTC as described above, including an Agent's Message in
     connection therewith, and all other documents required by the Letter of
     Transmittal and the instructions thereto, are received by the Depositary
     within three New York Stock Exchange trading days after the execution of
     such Notice of Guaranteed Delivery.

     In all cases, payment for Notes tendered and accepted for payment pursuant
to the Tender Offer will be made only after timely receipt by the Depositary of
certificates for such Notes or confirmation of book-entry transfer into the
Depositary's account at DTC a properly completed and duly executed Letter of
Transmittal (or manually signed facsimile thereof) or Agent's Message and any
other documents required by the Letter of Transmittal.

     Tender Constitutes an Agreement.  The proper tender of Notes pursuant to
any of the procedures described above will constitute a binding agreement
between the tendering Holders and the Company upon the terms and subject to the
conditions of the Tender Offer, and a representation that (i) such Holder owns
the Notes being tendered and is entitled to tender such Notes as contemplated by
the Tender Offer, all within the meaning of Rule 14e-1 under the Exchange Act
and (ii) the tender of such Notes complies with Rule 14e-4 under the Exchange
Act.

     Determination of Validity; Rejection of Notes; No Obligation to Give Notice
of Defects.  All questions as to the principal amount of Notes to be accepted,
the validity, form, eligibility (including the time of receipt) and acceptance
for payment of any tender of Notes pursuant to the procedures described herein
and the form and validity (including time of receipt of notices of withdrawal)
of all documents will be determined by the Company in its sole discretion, which
determination shall be final and binding on all parties. The Company reserves
the absolute right to reject any or all tendered Notes determined by it not to
be in proper form or the acceptance of or payment for which may be unlawful. The
Company also reserves the absolute right to waive any of the conditions of the
Tender Offer and any defect or irregularity in the tender of any particular
Notes.

                                       16
<PAGE>   17

The Company's interpretation of the terms and conditions of the Tender Offer
(including without limitation the instructions in the Letter of Transmittal)
shall be final and binding. No alternative, conditional or contingent tenders or
deliveries will be accepted. Unless waived, any irregularities in connection
with tenders of Notes must be cured within such time as the Company shall
determine. None of the Company, the Trustee, the Depositary, the Dealer Manager,
the Information Agent or any other person will be under any duty to give
notification of any defects or irregularities in such tenders of Notes or will
incur any liabilities for failure to give such notification. Tenders of Notes
will not be deemed to have been made until such irregularities have been cured
or waived. Any Notes received by the Depositary that are not properly tendered
and as to which the irregularities have not been cured or waived will be
returned by the Depositary to the tendering Holders (in the case of Notes
tendered by book-entry transfer into the Depositary's account at DTC, by
crediting the account maintained at DTC from which such Notes were delivered),
unless such Holders have otherwise provided in the Letter of Transmittal, as
promptly as practicable following the Expiration Date.

     Lost or Missing Certificates.  If a Holder desires to tender a Note
pursuant to the Tender Offer, but the Note has been mutilated, lost, stolen or
destroyed, such Holder should write to or telephone the Trustee at the address
listed below, about procedures for obtaining replacement certificates for such
Notes, arranging for indemnification or any other matter that requires handling
by such Trustee:

CONDITIONS OF THE TENDER OFFER

     Notwithstanding any other provision of the Tender Offer, the Company shall
not be required to accept for purchase, or to pay for, the Notes tendered
pursuant to the Tender Offer, and may terminate, extend or amend the Tender
Offer or delay or refrain (subject to Rule 14e-1(c) under the Exchange Act)
acceptance for purchase or payment of Notes so tendered, if, as of the
Expiration Date, any of the General Conditions have not been satisfied.

     The General Conditions shall be deemed to have been satisfied unless any of

of the Notes tendered pursuant to the Tender Offer (each of (1) through (7), a
"General Condition" and collectively, the "General Conditions"):

          (1) there shall have been threatened, instituted or pending any action
     or proceeding by or before any court or governmental regulatory or

     Tender Offer or otherwise relates in any manner to the Tender Offer;

          (2) a statute, rule, regulation, judgment, order, stay, decree or
     injunction shall have been threatened, proposed, sought, promulgated,
     enacted, entered, enforced or deemed to be applicable by any court or
     governmental regulatory or administrative agency, authority or tribunal,
     domestic or foreign, which, in the sole judgment of the Company, would or
     might directly or indirectly prohibit, prevent, restrict or delay
     consummation of the Tender Offer;

          (3) there shall have occurred or be likely to occur any event
     affecting the business or financial affairs of the Company that would or
     might prohibit, prevent, restrict or delay consummation of the Tender Offer
     or that will, or is reasonably likely to, materially impair the
     contemplated benefits of the Tender Offer to the Company or otherwise

     best interests of the Company;

     substantial state, national, or international calamity or emergency if the

     makes it impractical or inadvisable in the Company's view for the Company
     to proceed with the Tender Offer;

          (5) any change in the general political, market, economic or financial
     conditions in the United States or abroad that in the Company's opinion has
     or may have a material adverse effect with respect to the Company's
     business, operations or prospects or the trading in the securities of the
     Company, or any significant decline in either the Dow Jones Industrial
     Average or the Standard and Poor's Index of 500 Industrial companies in the

     consummation of the Tender Offer;

          (7) the Trustee under the Indenture shall have objected in any respect
     to, or taken any action that could, in the sole judgement of the Company,
     materially adversely affect the consummation of the Tender Offer, or shall
     have taken any action that challenges to validity or effectiveness of the
     procedures used by the Company in (a) making the Tender Offer or (b)

     Company, has or may have a material adverse effect on the Company or that
     would or might prohibit, prevent, restrict or delay consummation of the
     Tender Offer.

     The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company, in its sole discretion, regardless of the circumstances
giving rise to any such condition or may be waived by the Company in whole or in
part at any time and from time to time in the Company's sole discretion. The
failure by the Company at any time to exercise any of the foregoing rights shall
not be deemed a waiver of any such right and each such right shall be deemed an
ongoing right which may be asserted at any time.

one of the procedures described in "-- Procedures for Tendering Notes" at any
time on or prior to the Expiration Date.

     All questions as to the form and validity (including time of receipt) of
any notice of withdrawal will be determined by the Company, in its sole
discretion, which determination shall be final and binding. None of the Company,

BancBoston Robertson Stephens Inc. will receive a fee for their services as
Dealer Manager in connection with the Tender Offer that will depend on the
percentage of the aggregate principal amount of the Notes tendered for purchase
in the Tender Offer.

     The fee will be paid for each $1,000 principal amount of Notes tendered,

principal amount of Notes tendered above specified thresholds. The fee scale
ranges from $7.00 per $1,000 principal amount up to a maximum of $27.50 per
$1,000 principal amount if more than 90% of the aggregate principal amount of

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     The following summary is a general description of certain U.S. Federal
income tax consequences that apply to a sale of a Note pursuant to this Offer to
Purchase. This summary describes the tax consequences only to a Holder that is a
"U.S. Holder". For this purpose, a U.S. Holder is a beneficial owner of a Note
that is (i) a citizen or individual resident of the United States, (ii) a
corporation created or organized under the laws of the United States or any
State thereof (including the District of Columbia), (iii) an estate the income
of which is includible in gross income for U.S. Federal income tax purposes
regardless of its source or (iv) a trust the administration over which a U.S.
court is able to exercise primary supervision and all of the substantial
decisions of which one or more United States persons have the authority to
control.

     This summary does not purport to consider all the possible U.S. Federal
income tax consequences of a sale of a Note pursuant to this Offer to Purchase
and is not intended to reflect the individual tax position of any beneficial
owner. It deals only with a Note held as a capital asset. Moreover, it does not
address U.S. Holders with a special tax status or special tax situation, like
financial institutions, insurance companies, tax-exempt organizations, deferred
compensation plans or individual retirement accounts, dealers in securities or
currencies, persons whose functional currency is not the U.S. dollar, persons
subject to the alternative minimum tax or persons who hold a Note as part of a
straddle with other investments or as part of a "synthetic security" or other
integrated investment (including a "conversion transaction") comprised of a Note
and one or more other investments. This summary is based upon the U.S. Federal
income tax laws and regulations as now in effect and as currently interpreted
and does not take into account possible changes in those tax laws or
interpretations, any of which may apply retroactively. This summary does not
include any description of the tax laws of any state, local or foreign
governments that may apply to a Note or the Holder thereof. ALL HOLDERS ARE
URGED TO CONSULT THEIR OWN TAX ADVISERS AS TO THE PARTICULAR TAX CONSEQUENCES TO
THEM OF TENDERING A NOTE, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE,
LOCAL OR FOREIGN TAX LAWS.

     Sales of Notes Pursuant to the Tender Offer.  Subject to the market
discount rules discussed below, a U.S. Holder who receives cash for a Note
pursuant to the Tender Offer will recognize capital gain or loss equal to the
difference between the amount of cash received (excluding any amount
attributable to accrued interest, which will be taxable as ordinary income) and
the U.S. Holder's adjusted tax basis in the Note sold. Generally, a U.S.
Holder's adjusted tax basis in a Note will be the cost of the Note to the U.S.
Holder. A U.S. Holder's adjusted tax basis in a Note will increase by the amount
of market discount, if any, includible in income by the U.S. Holder pursuant to
an election to include market discount in gross income as it accrues, and
generally will decrease by the accrual of amortizable bond premium, if any, that
the U.S. Holder elects or has elected to offset against interest income on the
Note. Capital gain recognized on a sale of a Note held for more than one year
will be long-term capital gain. The excess of net long-term capital gain over
net short-term capital loss of certain noncorporate taxpayers for a taxable year
is subject to a maximum Federal income tax rate of 20 percent. In general,
limitations apply to the deductibility of capital losses.

     A U.S. Holder who acquired a Note at a market discount in excess of a de
minimis amount generally will be required to treat any gain on a sale of the
Note pursuant to the Tender Offer as ordinary income rather than capital gain to
the extent the gain does not exceed the market discount accrued on the Note as
of the date of sale, unless the U.S. Holder makes or has made an election to
include market discount on debt obligations in income as it accrues. In the case
of a Note, the amount of market discount generally will equal the excess of the
stated redemption price at maturity of the Note over the U.S. Holder's initial
tax basis in the Note. The amount of market discount is de minimis if it is less
than one quarter of one percent of the stated redemption price at maturity of
the Note multiplied by the number of complete years to maturity after the U.S.
Holder acquired the Note.

     Backup Withholding.  Backup withholding at the rate of 31% will apply to
the gross proceeds from the sale of a Note that is tendered and accepted for
payment unless the U.S. Holder (i) is a corporation or other exempt recipient
and, when required, establishes that exemption or (ii) accurately completes the
Substitute Form W-9 included in the Letter of Transmittal. A U.S. Holder that
does not provide his or its correct taxpayer identification number may be
subject to penalties imposed by the Internal Revenue Service (the

                                       21
<PAGE>   22

"IRS"). Any amount withheld under these rules will be refunded or credited
against the U.S. Holder's Federal income tax liability, provided certain
required information is reported to the IRS. See "Important Tax Information" in
the Letter of Transmittal.

     Information Reporting.  The Company will provide information statements to
tendering U.S. Holders and to the IRS reporting the cash payments, as required
by law.

Ladies and Gentlemen:

     By execution hereof, the undersigned acknowledges receipt of the Offer to
Purchase dated September 21, 1999 (the "Offer to Purchase") of SportsLine USA,
Inc., a Delaware corporation ("SportsLine"), relating to SportsLine's 5%
Convertible Subordinated Notes due 2006 (the "Notes") and this Letter of
Transmittal (the "Letter of Transmittal" and, together with the Offer to
Purchase, the "Offer Documents"), which together constitute SportsLine's offer
(the "Tender Offer") to purchase for cash any and all outstanding Notes, upon
the terms and subject to the conditions set forth in the Offer Documents. As of
September 21, 1999, $90.0 million aggregate principal amount of the Notes was
outstanding.

     Upon the terms and subject to the conditions of the Tender Offer, the
undersigned hereby tenders to SportsLine the principal amount of Notes indicated
above.

     Subject to, and effective upon, the acceptance for purchase of, and payment
for, the principal amount of Notes tendered with this Letter of Transmittal, the
undersigned hereby sells, assigns and transfers to, or upon the order of,
SportsLine all right, title and interest in and to the Notes that are being
tendered hereby. The undersigned hereby irrevocably constitutes and appoints the
Depositary the true and lawful agent and attorney-in-fact of the undersigned
(with full knowledge that the Depositary also acts as the agent of SportsLine)
with respect to such Notes, with full power of substitution (such
power-of-attorney being deemed to be an irrevocable power coupled with an
interest) to (i) present such Notes and all evidences of transfer and
authenticity to, or transfer ownership of, such Notes on the account books
maintained by DTC to, or upon the order of, SportsLine, (ii) present such Notes
for transfer of ownership on the books of the relevant security registrar, and
(iii) receive all benefits and otherwise exercise all rights of beneficial
ownership of such Notes, all in accordance with the terms of and conditions to
the Tender Offer as described in the Offer to Purchase.

     The undersigned understands that tenders of Notes may be withdrawn by
written notice of withdrawal received by the Depositary at any time prior to the
Expiration Date, and, thereafter, if the Tender Offer is terminated without any
Notes being purchased thereunder and as set forth below. In the event of a
termination of the Tender Offer, certificates representing Notes tendered
pursuant to the Tender Offer will be returned to the tendering Holder promptly
(or in the case of Notes tendered by book-entry transfer, such Notes will be
credited to the account maintained at DTC from which such Notes were delivered).
If, prior to the Expiration Date, SportsLine increases the Tender Offer
Consideration, any such changes in consideration would be applicable to all
Holders whose Notes are accepted for payment pursuant to the Tender Offer. In
addition, if at the time notice of any such change is first published, sent or
given to Holders, the Tender Offer is scheduled to expire at any time prior to
the tenth business day from and including the date that such notice is first
published, sent or given, the Tender Offer would be extended at least until the
expiration of such ten business day period.

     The undersigned understands that valid tenders of Notes pursuant to any of
the procedures described in the Offer to Purchase and in the instructions hereto
will constitute a binding agreement between the undersigned and SportsLine upon
the terms and subject to the conditions of the Tender Offer.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Notes tendered
hereby, and that when such Notes are accepted for purchase and payment by
SportsLine, SportsLine will acquire good title thereto, free and clear of all
liens, restrictions, charges and encumbrances and not subject to any adverse
claim or right. The undersigned will, upon request, execute and deliver any
additional documents deemed by the Depositary or by SportsLine to be necessary
or desirable to complete the sale, assignment and transfer of the Notes tendered
hereby.

     For purposes of the Tender Offer, the undersigned understands that
SportsLine will be deemed to have accepted for purchase validly tendered Notes
(or defectively tendered Notes with respect to which SportsLine has waived such
defect), if, as and when SportsLine gives oral (confirmed in writing) or written
notice thereof to the Depositary.

                                        4
<PAGE>   5

     The undersigned understands that, under certain circumstances and subject
to certain conditions of the Tender Offer (each of which SportsLine may waive)
set forth in the Offer to Purchase, SportsLine would not be required to accept
for purchase any of the Notes tendered. Any Notes not accepted for purchase will
be returned promptly to the undersigned at the address set forth above (or in
the case of Notes tendered by book-entry transfer, such Notes will be credited
to the account maintained at DTC from which such Notes were delivered), unless
otherwise indicated herein under "Special Delivery Instructions" below.

     All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death or incapacity of the undersigned and every
obligation of the undersigned under this Letter of Transmittal shall be binding
upon the undersigned's heirs, personal representatives, executors,
administrators, successors, assigns, trustees in bankruptcy and other legal
representatives.

     The undersigned understands that the delivery and surrender of the Notes is
not effective, and the risk of loss of the Notes does not pass to the
Depositary, until receipt by the Depositary (whether through DTC's ATOP
procedures for transfer or otherwise) of this Letter of Transmittal (or an
Agent's Message in the case of an ATOP transfer), or a manually signed facsimile
hereof, properly completed and duly executed, together with all accompanying
evidences of authority and any other required documents in form satisfactory to
SportsLine. All questions as to the form of all documents and the validity
(including time of receipt) and acceptance of tenders and withdrawals of Notes
will be determined by SportsLine, in its sole discretion, which determination
shall be final and binding.

     Unless otherwise indicated herein under "Special Issuance Instructions,"
the undersigned hereby requests that any Notes representing principal amounts
not tendered or not accepted for purchase be issued in the name(s) of the
undersigned (and in the case of Notes tendered by book-entry transfer, by credit
to the account at DTC), and checks for payments of the Tender Offer
Consideration, as the case may be, to be made in connection with the Tender
Offer be issued to the order of the undersigned. Similarly, unless otherwise
indicated herein under "Special Delivery Instructions," the undersigned hereby
requests that any Notes representing principal amounts not tendered or not
accepted for purchase and checks for payments of the Tender Offer Consideration
to be made in connection with the Tender Offer be delivered to the undersigned
at the address(es) shown above. In the event that the "Special Issuance
Instructions" box or the "Special Delivery Instructions" box is, or both are,
completed, the undersigned hereby requests that any Notes representing principal
amounts not tendered or not accepted for purchase be issued in the name(s) of,
certificates for such Notes be delivered to, and checks for payments of the
Tender Offer Consideration to be made in connection with the Tender Offer be
issued in the name(s) of, and be delivered to, the person(s) at the addresses so
indicated. The undersigned recognizes that SportsLine has no obligation pursuant
to the "Special Issuance Instructions" box or "Special Delivery Instructions"
box to transfer any Notes from the name of the registered Holder(s) thereof if
SportsLine does not accept for purchase any of the principal amount of such
Notes so tendered.

                                  INSTRUCTIONS

          FORMING PART OF THE TERMS AND CONDITIONS OF THE TENDER OFFER

     1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES FOR NOTES OR
BOOK-ENTRY CONFIRMATIONS; GUARANTEED DELIVERY PROCEDURES; WITHDRAWAL OF
TENDERS. To tender Notes in the Tender Offer, physical delivery of certificates
for Notes or a confirmation of any book-entry transfer into the Depositary's
account with DTC of Notes tendered electronically, as well as a properly
completed and duly executed copy or manually signed facsimile of this Letter of
Transmittal, and any other documents required by this Letter of Transmittal,
must be received by the Depositary at one of its addresses set forth herein on
or prior to the Expiration Date. The Depositary and DTC have confirmed that the
Tender Offer is eligible for ATOP. Accordingly, DTC participants may
electronically transmit their acceptance of the Tender Offer by causing DTC to
transfer Notes to the Depositary in accordance with DTC's ATOP procedures for
transfer in lieu of delivering this Letter of Transmittal. DTC will then send an
Agent's Message (as defined in the Offer to Purchase) to the Depositary. The
method of delivery of this Letter of Transmittal, Notes and all other required
documents to the Depositary is at the election and risk of Holders. If such
delivery is by mail, it is suggested that Holders use properly insured
registered mail with return receipt requested, and that the mailing be made
sufficiently in advance of the Expiration Date to permit delivery to the
Depositary prior to such date. No alternative, conditional or contingent tenders
of Notes will be accepted. HOLDERS DESIRING TO TENDER NOTES ON THE EXPIRATION
DATE SHOULD NOTE THAT SUCH HOLDERS MUST ALLOW SUFFICIENT TIME FOR COMPLETION OF
THE ATOP PROCEDURES DURING THE NORMAL BUSINESS HOURS OF DTC ON THAT DATE. Except
as otherwise provided below, the delivery will be deemed made when actually
received or confirmed by the Depositary. THIS LETTER OF TRANSMITTAL AND THE
NOTES SHOULD BE SENT ONLY TO THE DEPOSITARY, NOT TO SPORTSLINE, THE TRUSTEE, THE
INFORMATION AGENT OR THE DEALER MANAGER. DELIVERY OF DOCUMENTS TO DTC DOES NOT
CONSTITUTE DELIVERY TO THE DEPOSITARY.

     If a Holder desires to tender Notes pursuant to the Tender Offer and (a)
certificates representing such Notes are not lost but are not immediately
available, (b) time will not permit this Letter of Transmittal, certificates
representing such Notes and all other required documents to reach the Depositary
on or prior to the Expiration Date, or (c) the procedures for book-entry
transfer cannot be completed on or prior to the Expiration Date, a tender may be
effected if all the following are complied with:

          (a) such tender is made by or through an Eligible Institution;

          (b) on or prior to the Expiration Date, the Depositary has received
     from such Eligible Institution at one of the addresses of the Depositary
     set forth on the first page of this Letter of Transmittal, a properly
     completed and validly executed Notice of Guaranteed Delivery (by manually
     signed facsimile transmission, mail or hand delivery) in substantially the
     form provided with the Offer to Purchase, setting forth the name(s) and
     addressees of the registered Holder(s) and the principal amount of Notes
     being tendered and stating that the tender is being made thereby and
     guaranteeing that, within three New York Stock Exchange ("NYSE") trading
     days after the date of execution of the Notice of Guaranteed Delivery, the
     applicable Letter of Transmittal properly completed and validly executed
     (or a manually signed facsimile thereof or Agent's Message in lieu
     thereof), together with certificates representing the Notes (or
     confirmation of book-entry transfer of such Notes into the Depositary's
     account with DTC) and any other documents required by the Letter of
     Transmittal and the instructions thereto, will be deposited by such
     Eligible Institution with the Depositary; and

          (c) this Letter of Transmittal (or a manually signed facsimile
     thereof), properly completed and validly executed with any required
     signature guarantees or Agent's Message in lieu thereof, together with
     certificates for all Notes in proper form for transfer (or confirmation of
     book-entry transfer of such Notes into the Depositary's account with DTC),
     and any other required documents are received by the Depositary within
     three NYSE trading days after the date of execution of such Notice of
     Guaranteed Delivery.

                                        8
<PAGE>   9

     Tenders of Notes may be validly withdrawn at any time on or prior to the
Expiration Date. Holders who wish to exercise their right of withdrawal with
respect to the Tender Offer must give written notice of withdrawal delivered by
mail, hand delivery or manually signed facsimile transmission, which notice must
be received by the Depositary at one of its addresses set forth on the first
page of this Letter of Transmittal on or prior to the Expiration Date. In order
to be valid, a notice of withdrawal must specify the name of the person who
deposited the Notes to be withdrawn (the "Depositor"), the name in which the
Notes are registered (or, if tendered by book-entry transfer, the name of the
DTC participant whose name appears on the security position listing as the owner
of such Notes), if different from that of the Depositor, and the principal
amount of Notes to be withdrawn. If certificates have been delivered or
otherwise identified (through confirmation of book-entry transfer of such Notes)
to the Depositary, the name of the Holder and the certificate number or numbers
relating to such Notes withdrawn must also be furnished to the Depositary as
aforesaid prior to the physical release of the certificates for the withdrawn
Notes (or, in the case of Notes transferred by book-entry transfer, the name and
number of the account at DTC to be credited with withdrawn Notes). The notice of
withdrawal must be signed by the Holder in the same manner as this Letter of
Transmittal (including, in any case, any required signature guarantees), or be
accompanied by evidence satisfactory to SportsLine that the person withdrawing
the tender has succeeded to be the beneficial owner of such Notes. Withdrawals
of tendered Notes may not be rescinded and any Notes withdrawn will thereafter
be deemed not validly tendered for purposes of the Tender Offer. However,
validly withdrawn Notes may be retendered by following the procedures therefor
described in the Offer to Purchase at any time on or prior to the Expiration
Date.

     2. PARTIAL TENDERS. Tenders of Notes pursuant to the Tender Offer will be
accepted only in respect of principal amounts equal to $1,000 or integral
multiples thereof. If less than the entire principal amount of any Notes
evidenced by a submitted certificate is tendered, the tendering Holder must fill
in the principal amount tendered in the last column of the box entitled
"Description of Notes" herein. The entire principal amount represented by the
certificates for all Notes delivered to the Depositary will be deemed to have
been tendered unless otherwise indicated. If the entire principal amount of all
Notes is not tendered or not accepted for purchase, Notes representing such
untendered or unaccepted amount will be sent (or if tendered by book-entry
transfer, returned by credit to the account at DTC designated herein) to the
Holder unless otherwise provided in the appropriate box on this Letter of
Transmittal (see Instruction 4), promptly after the Notes are accepted for
purchase.

     3. SIGNATURES ON THIS LETTER OF TRANSMITTAL, BOND POWERS AND ENDORSEMENT;
GUARANTEE OF SIGNATURES. If this Letter of Transmittal is signed by the
registered Holder(s) of the Notes tendered hereby, the signature(s) must
correspond with the name(s) as written on the face of the certificate(s) without
alteration, enlargement or any change whatsoever. If this Letter of Transmittal
is signed by a DTC participant whose name is shown as the owner of the Notes
tendered hereby, the signature must correspond with the name shown on the
security position listing, as the owner of the Notes.

     If any of the Notes tendered hereby are registered in the name of two or
more Holders, all such Holders must sign this Letter of Transmittal. If any
tendered Notes are registered in different names on several certificates, it
will be necessary to complete, sign and submit as many separate copies of this
Letter of Transmittal and any necessary accompanying documents as there are
different names in which certificates are held.

     If this Letter of Transmittal is signed by the Holder, and the certificates
for any principal amount of Notes not tendered or not accepted for purchase are
to be issued (or if any principal amount of Notes that is not tendered or not
accepted for purchase is to be reissued or returned) to or, if tendered by
book-entry transfer, credited to the account at DTC of the Holder, and checks
for payments of the Tender Offer Consideration to be made in connection with the
Tender Offer are to be issued to the order of the Holder, then the Holder need
not endorse any certificates for tendered Notes, nor provide a separate bond
power. In any other case (including if this Letter of Transmittal is not signed
by the Holder), the Holder either must properly endorse the certificates for
Notes tendered or transmit a separate properly completed bond power with this
Letter of Transmittal (in either case, executed exactly as the name(s) of the
registered Holder(s) appear(s) on such Notes, and, with respect to a DTC
participant whose name appears on a security position listing as the owner of
Notes, exactly as the name(s) of the participants appear(s) on such security
position
                                        9

listing), with the signature on the endorsement or bond power guaranteed by an
Eligible Institution, unless such certificates or bond powers are executed by an
Eligible Institution.

     If this Letter of Transmittal or any certificates for Notes or bond powers
are signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting, in a fiduciary, or representative
capacity, such persons should so indicate when signing and proper evidence
satisfactory to SportsLine of their authority so to act must be submitted with
this Letter of Transmittal.

     Endorsements on certificates for Notes and signatures on bond powers
provided in accordance with this Instruction 3 by registered Holders not
executing this Letter of Transmittal must be guaranteed by an Eligible
Institution, unless the signature is that of an Eligible Institution.

     No signature guarantee is required if (i) this Letter of Transmittal is
signed by the registered Holder(s) of the Notes tendered herewith (or by a DTC
participant whose name appears on a security position listing as the owner of
Notes) and the payment of the Tender Offer Consideration is to be made, or if
any Notes for principal amounts not tendered or not accepted for purchase are to
be issued, directly to such Holder(s) (or, if tendered by a DTC participant, any
Notes for principal amounts not tendered or not accepted for purchase are to be
credited to such participant's account at DTC) and neither the "Special Issuance
Instructions" box nor the "Special Delivery Instructions" box of this Letter of
Transmittal has been completed or (ii) such Notes are tendered for the account
of an Eligible Institution. In all other cases, all signatures on Letters of
Transmittal and endorsements on certificates, signatures on bond powers
accompanying Notes must be guaranteed by an Eligible Institution, unless the
signature is that of an Eligible Institution.

     4. SPECIAL PAYMENT AND SPECIAL DELIVERY INSTRUCTIONS. Tendering Holders
should indicate in the applicable box or boxes the name and address to which
Notes for principal amounts not tendered or not accepted for purchase or checks
for payment of the Tender Offer Consideration to be made in connection with the
Tender Offer are to be issued or sent, if different from the name and address of
the registered or acting Holder signing this Letter of Transmittal. In the case
of issuance in a different name, the taxpayer identification or social security
number of the person named must also be indicated. If no instructions are given,
Notes not tendered or not accepted for purchase will be returned to the
registered or acting Holder of the Notes tendered. Any Holder tendering by
book-entry transfer may request that Notes not tendered or not accepted for
purchase be credited to such account at DTC as such Holder may designate under
the caption "Special Issuance Instructions." If no such instructions are given,
any such Notes not tendered or not accepted for purchase will be returned by
crediting the DTC account designated above.

     5. SUBSTITUTE FORM W-9. Each tendering Holder is required to provide the
Depositary with the Holder's correct taxpayer identification number ("TIN") and
federal employer identification number, on Substitute Form W-9, which is
provided under "Important Tax Information" below, or, alternatively, to
establish another basis for exemption from backup withholding. A Holder must
cross out item (2) in the Certification box on Substitute Form W-9 if such
Holder is subject to backup withholding. Failure to provide the information on
the form may subject the tendering Holder to 31% federal income tax backup
withholding on the payments made to the Holder or other payee with respect to
Notes purchased pursuant to the Tender Offer. The box in Part 3 of the form
should be checked if the tendering Holder has not been issued a TIN and has
applied for a TIN or intends to apply for a TIN in the near future. If the box
in Part 3 is checked and the Depositary is not provided with a TIN, thereafter
the Depositary will withhold 31% on all such payments of the Tender Offer
Consideration until a TIN is provided to the Depositary.

     6. TRANSFER TAXES. SportsLine will pay all transfer taxes applicable to the
purchase and transfer of Notes pursuant to the Tender Offer, except in the case
of deliveries of certificates for Notes for principal amounts not tendered or
not met that are registered or issued in the name of any person other than the
registered or acting Holder of Notes tendered thereby. Except as provided in
this Instruction 6, it will not be necessary for transfer tax stamps to be
affixed to the certificates listed in this Letter of Transmittal.

     7. IRREGULARITIES. All questions as to the form of all documents and the
validity (including time of receipt) and acceptance of tenders and withdrawals
of Notes will be determined by SportsLine, in its sole discretion, which
determination shall be final and binding. ALTERNATIVE, CONDITIONAL OR CON-

                                       10
<PAGE>   11

TINGENT TENDERS WILL NOT BE CONSIDERED VALID. SportsLine reserves the absolute
right to reject any or all tenders of Notes that are not in proper form or the
acceptance of which would, in SportsLine's opinion, be unlawful. SportsLine also
reserves the right to waive any defects, irregularities or conditions of tender
as to particular Notes. SportsLine's interpretations of the terms and conditions
of the Tender Offer (including the instructions in this Letter of Transmittal)
will be final and binding. Any defect or irregularity in connection with tenders
of Notes must be cured within such time as SportsLine determines, unless waived
by SportsLine. Tenders of Notes shall not be deemed to have been made until all
defects or irregularities have been waived by SportsLine or cured. All tendering
Holders, by execution of this Letter of Transmittal or a manually signed
facsimile hereof, waive any right to receive notice of the acceptance of their
Notes for purchase. None of SportsLine, the Depositary, the Dealer Manager, the
Information Agent, the Trustee or any other person will be under any duty to
give notice of any defects or irregularities in tenders of Notes, or will incur
any liability to Holders for failure to give any such notice.

     8. WAIVER OF CONDITIONS. SportsLine expressly reserves the absolute right,
in its sole and absolute discretion, to amend or waive any of the conditions to
the Tender Offer in the case of any Notes tendered, in whole or in part, at any
time and from time to time.

     9. MUTILATED, LOST, STOLEN OR DESTROYED CERTIFICATES FOR NOTES. Any Holder
whose certificates for Notes have been mutilated, lost, stolen or destroyed
should write to or telephone the Trustee at the address or telephone number set
forth in the Offer to Purchase.

     10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions relating to the
procedure for tendering Notes and requests for assistance or additional copies
of the Offer to Purchase and this Letter of Transmittal may be directed to the
Information Agent whose address and telephone number appear below. A Holder may
also contact such Holder's broker, dealer, commercial bank, trust company or
nominee for assistance concerning the Tender Offer.

                                       11
<PAGE>   12

                           IMPORTANT TAX INFORMATION

     Under federal income tax law, a Holder whose tendered Notes are accepted
for purchase or exchange is required to provide the Depositary with such
Holder's current TIN on Substitute Form W-9 below. If such Holder is an
individual, the TIN is his social security number. If the Depositary is not
provided with the correct TIN, the Holder or other payee may be subject to a $50
penalty imposed by the Internal Revenue Service. In addition, any Offer
Consideration paid to such Holder or other payee with respect to Notes purchased
pursuant to the Offer may be subject to 31% backup withholding tax.

     Certain Holders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, that Holder must submit to the Depositary a properly completed
Internal Revenue Service Form W-8 (a "Form W-8") signed under penalties of
perjury, attesting to that individual's exempt status. A Form W-8 can be
obtained from the Depositary. See the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for additional
instructions.

     If backup withholding applies, the Depositary is required to withhold 31%
of any Offer Consideration paid to the Holder or other payee. Backup withholding
is not an additional tax. Rather, the federal income tax liability of persons
subject to backup withholding will be reduced by the amount of tax withheld. If
withholding results in an overpayment of taxes, a refund may be obtained from
the Internal Revenue Service.

PURPOSE OF SUBSTITUTE FORM W-9

     To prevent backup withholding on any Offer Consideration paid to a Holder
or other payee with respect to Notes purchased pursuant to the Offer, the Holder
is required to notify the Depositary of the Holder's current TIN (or the TIN of
any other payee) by completing the form below, certifying that (i) the TIN
provided on Substitute Form W-9 is correct (or that such Holder is awaiting a
TIN) and that (ii) the Holder is not subject to backup withholding because (a)
the Holder has not been notified by the Internal Revenue Service that the Holder
is subject to backup withholding as a result of failure to report all interest
or dividends or (b) the Internal Revenue Service has notified the Holder that
the Holder is no longer subject to backup withholding.

WHAT NUMBER TO GIVE THE DEPOSITARY

     The Holder is required to give the Depositary the TIN (e.g., social
security number or employer identification number) of the record owner of the
Notes. If the Notes are registered in more than one name or are not registered
in the name of the actual owner, consult the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9," for
additional guidance on which number to report.

Exempt Payees described above should file form W-9 to avoid possible erroneous
backup withholding. FILE THIS FORM WITH THE PAYER, FURNISH YOUR TAXPAYER
IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, AND RETURN IT TO
THE PAYER. IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE DIVIDENDS, ALSO
SIGN AND DATE THE FORM.

     Certain payments other than interest, dividends, and patronage dividends,
that are not subject to information reporting are also not subject to backup
withholding. For details, see the regulations under sections 6041, 6041(A)(a),

     PRIVACY ACT NOTICE. -- Section 6109 requires most recipients of dividend,
interest or other payments to give taxpayer identification numbers to payers who
must report the payments to IRS. IRS uses the numbers for identification
purposes. Payers must be given the numbers whether or not recipients are
required to file tax returns. Beginning January 1, 1993, payers must generally
withhold 31% of taxable interest, dividend, and certain other payments to a
payee who does not furnish a taxpayer identification number to a payer. Certain
penalties may also apply.

(1) PENALTIES FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. -- If you
fail to furnish your taxpayer identification number to a payer, you are subject
to a penalty of $50 for each such failure unless your failure is due to a
reasonable cause and not to willful neglect.

(2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS. -- If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
underpayment attributable to that failure unless there is clear and convincing
evidence to the contrary.

(3) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING -- If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.

(4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION. -- Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.
