COUPON

         A coupon of $[      ] per ELKS will be paid in cash on April 2, 2002
and a coupon of $[      ] per ELKS will be paid in cash on October 2, 2002. The
April 2, 2002 coupon will be composed of $[      ] of interest and a partial
payment of an option premium in the amount of $[      ]. The [      ], 2002
coupon will be composed of $[      ] of interest and a partial payment of an
option premium in the amount of $[      ]. Coupon payments will be payable to
the persons in whose names the ELKS are registered at the close of business on
the Business Day preceding each Interest Payment Date. If an Interest Payment
Date falls on a day that is not a Business Day, the coupon payment to be made on
such Interest Payment Date will be made on the next succeeding Business Day with
the same force and effect as if made on such Interest Payment Date, and no
additional interest will accrue as a result of such delayed payment.

         "Business Day" means any day that is not a Saturday, a Sunday or a day
on which the AMEX or banking institutions or trust companies in the City of New
York are authorized or obligated by law or executive order to close.

         The interest portion of the coupon will represent interest accruing at
a rate of [      ]% per annum from [      ], 2001 or from the most recent
Interest Payment Date to which the interest portion of the coupon has been paid
or provided for until maturity. The interest portion of the coupon will be
computed on the basis of a 360-day year of twelve 30-day months.

PAYMENT AT MATURITY

         On the Stated Maturity Date, Holders of the ELKS will receive for each
ELKS the Maturity Payment described below.

DETERMINATION OF THE MATURITY PAYMENT

         The Maturity Payment for each ELKS equals either:

         -     a number of shares of Sun Microsystems common stock equal to the
               Exchange Rate, if the Trading Price of Sun Microsystems common
               stock on any Trading Day after [      ], 2001 up to and including
               the third Trading Day before the Stated Maturity Date is less
               than or equal to $[ ], or

         -     $10 in cash.

         In lieu of any fractional share of Sun Microsystems common stock
otherwise payable in respect of any ELKS, at the Stated Maturity Date, the
Holder of this Note will receive an amount in cash equal to the value of such
fractional share of Sun Microsystems common stock, based on the Closing Price of
Sun Microsystems common stock on the third Trading Day before the Stated
Maturity Date. The number of full shares of Sun Microsystems common stock, and
any cash in lieu of a fractional share, to be delivered at the Stated Maturity
Date to the Holder of this Note will be calculated based on the aggregate number
of ELKS held by such Holder.



                                       2
<PAGE>   3
         The "Closing Price" of Sun Microsystems common stock (or any other
security for which a Closing Price must be determined) on any date of
determination will be (1) if the common stock is listed on a national securities
exchange on that date of determination, the closing sale price or, if no closing
sale price is reported, the last reported sale price on that date on the
principal U.S. exchange on which the common stock is listed or admitted to
trading, (2) if the common stock is not listed on a national securities exchange
on that date of determination, or if the closing sale price or last reported
sale price is not obtainable (even if the common stock is listed or admitted to
trading on such exchange), and the common stock is quoted on the Nasdaq National
Market, the closing sale price or, if no closing sale price is reported, the
last reported sale price of one share of Sun Microsystems common stock on that
date as reported on the Nasdaq National Market, and (3) if Sun Microsystems
common stock is not quoted on the Nasdaq on that date of determination or, if
the closing sale price or last reported sale price is not obtainable (even if
the common stock is quoted on the Nasdaq), the last quoted bid price for Sun
Microsystems common stock in the over-the-counter market on that date as
reported by the OTC Bulletin Board, the National Quotation Bureau or a similar
organization. If no closing sale price or last reported sale price is available
pursuant to clauses (1), (2) or (3) of the preceding sentence because of a
Market Disruption Event or otherwise, the Closing Price on any date of
determination will be the arithmetic mean, as determined by the calculation
agent for the ELKS, of the bid prices of Sun Microsystems common stock obtained
from as many dealers in such stock (which may include Salomon Smith Barney Inc.
or any of the Company's other subsidiaries or affiliates), but not exceeding
three such dealers, as will make such bid prices available to the calculation
agent for the ELKS. A security "quoted on the Nasdaq National Market" will
include a security included for listing or quotation in any successor to such
system and the term "OTC Bulletin Board" will include any successor to such
service.

         The "Exchange Rate" will equal [      ].

         The "Initial Share Price" will equal $[     ], the price per share of
Sun Microsystems common stock at the market close on [       ], 2001.

         A "Trading Day" means a day, as determined by the calculation agent for
the ELKS, on which trading is generally conducted (or was scheduled to have been
generally conducted, but for the occurrence of a Market Disruption Event) on the
New York Stock Exchange, the AMEX, the Nasdaq National Market, the Chicago
Mercantile Exchange and the Chicago Board Options Exchange, and in the
over-the-counter market for equity securities in the United States.

         A "Market Disruption Event" means the occurrence or existence of any
suspension of or limitation imposed on trading (by reason of movements in price
exceeding limits permitted by any exchange or market or otherwise) of, or the
unavailability, through a recognized system of public dissemination of
transaction information, of accurate price, volume or related information in
respect of, (1) the shares of Sun Microsystems common stock on any exchange or
market, or (2) any options contracts or futures contracts relating to the shares
of Sun Microsystems common stock, or any options on such futures contracts, on
any exchange or market if, in each case, in the determination of the calculation
agent for the ELKS, any such suspension, limitation or unavailability is
material.



                                       3
<PAGE>   4
         The "Trading Price" of Sun Microsystems common stock (or any other
common stock for which a Trading Price must be determined) on any date of
determination will be (1) if the common stock is listed on a national securities
exchange on that date of determination, any reported sale price, regular way, of
the principal trading session on that date on the principal U.S. exchange on
which the common stock is listed or admitted to trading, (2) if the common
stock is not listed on a national securities exchange on that date of
determination, or if the reported sale price on such exchange is not obtainable
(even if the common stock is listed or admitted to trading on such exchange),
and the common stock is quoted on the Nasdaq National Market, any reported sale
price of the principal trading session on that date as reported on the Nasdaq,
and (3) if the common stock is not quoted on the Nasdaq on that date of
determination, or if the reported sale price on the Nasdaq is not obtainable
(even if the common stock is quoted on the Nasdaq), any reported price of the
principal trading session on the over-the-counter market on that date as
reported on the OTC Bulletin Board, the national Quotation Bureau or a similar
organization. The  determination of the Trading Price by the calculation agent
for the ELKS in the event of a Market Disruption Event may be deferred by the
calculation agent for the ELKS for up to five consecutive Trading Days on which
a Market Disruption Event is occurring. If no reported sale price of the
principal trading session is available pursuant to clauses (1), (2) or (3) above
or if there is a Market Disruption Event, the Trading Price on any date of
determination, unless deferred by the calculation agent for the ELKS as
described in the preceding sentence,  will be the arithmetic mean, as determined
by the calculation agent for the ELKS, of the bid prices of the common stock
obtained from as many dealers in such stock (which may include Salomon Smith
Barney Inc. or any of the Company's other subsidiaries or affiliates), but not
exceeding three such dealers, as will make such bid prices available to the
calculation agent for the ELKS. A security "quoted on the Nasdaq National
Market" will include a security included for listing or quotation in any
successor to such system and the term "OTC Bulletin Board" will include any
successor to such service.

DILUTION ADJUSTMENTS

         If Sun Microsystems, after the closing date of the offering of the
ELKS,

         (1)   pays a stock dividend or makes a distribution with respect to its
               common stock in shares of the stock,

         (2)   subdivides or splits the outstanding shares of its common stock
               into a greater number of shares,

         (3)   combines the outstanding shares of the common stock into a
               smaller number of shares, or

         (4)   issues by reclassification of shares of its common stock any
               shares of other common stock of Sun Microsystems,

then, in each of these cases, the Exchange Rate will be multiplied by a dilution
adjustment equal to a fraction, the numerator of which will be the number of
shares of common stock outstanding immediately after the event, plus, in the
case of a reclassification referred to in (4) above, the


                                       4
<PAGE>   5
number of shares of other common stock of Sun Microsystems, and the denominator
of which will be the number of shares of common stock outstanding immediately
before the event.

         If Sun Microsystems, after the closing date, issues, or declares a
record date in respect of an issuance of, rights or warrants to all holders of
its common stock entitling them to subscribe for or purchase shares of its
common stock at a price per share less than the Then-Current Market Price of the
common stock, other than rights to purchase common stock pursuant to a plan for
the reinvestment of dividends or interest, then, in each of these cases, the
Exchange Rate will be multiplied by a dilution adjustment equal to a fraction,
the numerator of which will be the number of shares of common stock outstanding
immediately before the adjustment is effected, plus the number of additional
shares of common stock offered for subscription or purchase pursuant to the
rights or warrants, and the denominator of which will be the number of shares of
common stock outstanding immediately before the adjustment is effected by reason
of the issuance of the rights or warrants, plus the number of additional shares
of common stock which the aggregate offering price of the total number of shares
of common stock offered for subscription or purchase pursuant to the rights or
warrants would purchase at the Then-Current Market Price of the common stock,
which will be determined by multiplying the total number of shares so offered
for subscription or purchase by the exercise price of the rights or warrants and
dividing the product obtained by the Then-Current Market Price. To the extent
that, after the expiration of the rights or warrants, the shares of common stock
offered thereby have not been delivered, the Exchange Rate will be further
adjusted to equal the Exchange Rate which would have been in effect had the
adjustment for the issuance of the rights or warrants been made upon the basis
of delivery of only the number of shares of common stock actually delivered.

         If Sun Microsystems, after the closing date, declares or pays a
dividend or makes a distribution to all holders of the common stock of any class
of its capital stock, the capital stock of one or more of its subsidiaries,
evidences of its indebtedness or other non-cash assets, excluding any dividends
or distributions referred to in the above paragraph, or issues to all holders of
its common stock rights or warrants to subscribe for or purchase any of its or
one or more of its subsidiaries' securities, other than rights or warrants
referred to in the above paragraph, then, in each of these cases, the Exchange
Rate will be multiplied by a dilution adjustment equal to a fraction, the
numerator of which will be the Then-Current Market Price of one share of the
common stock, and the denominator of which will be the Then-Current Market Price
of one share of the common stock, less the fair market value (as determined by a
nationally recognized independent investment banking firm retained for this
purpose by the Company, whose determination will be final) as of the time the
adjustment is effected of the portion of the capital stock, assets, evidences of
indebtedness, rights or warrants so distributed or issued applicable to one
share of common stock.

         Notwithstanding the foregoing, in the event that, with respect to any
dividend or distribution to which the above paragraph would otherwise apply, the
denominator in the fraction referred to in the above formula is less than $1.00
or is a negative number, then the Company may, at its option, elect to have the
adjustment provided by this paragraph not be made and in lieu of this
adjustment, at maturity, each Holder of the ELKS will be entitled to receive an
additional amount of cash equal to the product of the number of ELKS held by the
holder multiplied by the fair market value of the capital stock, indebtedness,
assets, rights or warrants


                                       5
<PAGE>   6
(determined, as of the date this dividend or distribution is made, by a
nationally recognized independent investment banking firm retained for this
purpose by the Company, whose determination will be final) so distributed or
issued applicable to a number of shares of Sun Microsystems common stock equal
to the Exchange Rate.

         If Sun Microsystems, after the closing date, declares a record date in
respect of a distribution of cash, other than any Permitted Dividends described
below, any cash distributed in consideration of fractional shares of common
stock and any cash distributed in a Reorganization Event referred to below, by
dividend or otherwise, to all holders of its common stock, or makes an Excess
Purchase Payment, then the Exchange Rate will be multiplied by a dilution
adjustment equal to a fraction, the numerator of which will be the Then-Current
Market Price of the common stock, and the denominator of which will be the
Then-Current Market Price of the common stock on the record date less the amount
of the distribution applicable to one share of common stock which would not be a
Permitted Dividend, or, in the case of an Excess Purchase Payment, less the
aggregate amount of the Excess Purchase Payment for which adjustment is being
made at the time divided by the number of shares of Sun Microsystems common
stock outstanding on the record date.

         For the purposes of these adjustments:

         A "Permitted Dividend" is any quarterly cash dividend in respect of Sun
Microsystems common stock, other than a quarterly cash dividend that exceeds the
immediately preceding quarterly cash dividend, and then only to the extent that
the per share amount of this dividend results in an annualized dividend yield on
the common stock in excess of 10%.

         An "Excess Purchase Payment" is the excess, if any, of (x) the cash and
the value (as determined by a nationally recognized independent investment
banking firm retained for this purpose by the Company, whose determination will
be final) of all other consideration paid by Sun Microsystems with respect to
one share of common stock acquired in a tender offer or exchange offer by Sun
Microsystems, over (y) the Then-Current Market price of the common stock.

         Notwithstanding the foregoing, in the event that, with respect to any
dividend or distribution or Excess Purchase Payment to which the fifth paragraph
in this section would otherwise apply, the denominator in the fraction referred
to in the formula in that paragraph is less than $1.00 or is a negative number,
then the Company may, at its option, elect to have the adjustment provided by
the fifth paragraph in this section not be made and in lieu of this adjustment,
at maturity, each Holder of the ELKS will be entitled to receive an additional
amount of cash equal to the product of the number of ELKS held by the Holder
multiplied by the sum of the amount of cash plus the fair market value of other
consideration (determined, as of the date this dividend or distribution is made,
by a nationally recognized independent investment banking firm retained for this
purpose by the Company, whose determination will be final) so distributed or
applied to the acquisition of the common stock in the tender offer or exchange
offer applicable to a number of shares of Sun Microsystems common stock equal to
the Exchange Rate.



                                       6
<PAGE>   7
         Each dilution adjustment will be effected as follows:

         -     in the case of any dividend, distribution or issuance, at the
               opening of business on the Business Day next following the record
               date for determination of holders of Sun Microsystems common
               stock entitled to receive this dividend, distribution or issuance
               or, if the announcement of this dividend, distribution, or
               issuance is after this record date, at the time this dividend,
               distribution or issuance was announced by Sun Microsystems,

         -     in the case of any subdivision, split, combination or
               reclassification, on the effective date of the transaction,

         -     in the case of any Excess Purchase Payment for which Sun
               Microsystems announces, at or prior to the time it commences the
               relevant share repurchase, the repurchase price per share for
               shares proposed to be repurchased, on the date of the
               announcement, and

         -     in the case of any other Excess Purchase Payment, on the date
               that the holders of the repurchased shares become entitled to
               payment in respect thereof.

         All dilution adjustments will be rounded upward or downward to the
nearest 1/10,000th or, if there is not a nearest 1/10,000th, to the next lower
1/10,000th. No adjustment in the Exchange Rate will be required unless the
adjustment would require an increase or decrease of at least one percent
therein, provided, however, that any adjustments which by reason of this
sentence are not required to be made will be carried forward (on a percentage
basis) and taken into account in any subsequent adjustment. If any announcement
or declaration of a record date in respect of a dividend, distribution, issuance
or repurchase requiring an adjustment as described herein is subsequently
canceled by Sun Microsystems, or this dividend, distribution, issuance or
repurchase fails to receive requisite approvals or fails to occur for any other
reason, then, upon the cancellation, failure of approval or failure to occur,
the Exchange Rate will be further adjusted to the Exchange Rate which would then
have been in effect had adjustment for the event not been made. If a
Reorganization Event described below occurs after the occurrence of one or more
events requiring an adjustment as described herein, the dilution adjustments
previously applied to the Exchange Rate will not be rescinded but will be
applied to the new Exchange Rate provided for below.

         The "Then-Current Market Price" of the common stock, for the purpose of
applying any dilution adjustment, means the average Closing Price per share of
common stock for the 10 Trading Days immediately before this adjustment is
effected or, in the case of an adjustment effected at the opening of business on
the Business Day next following a record date, immediately before the earlier of
the date the adjustment is effected and the related Ex-Date. For purposes of
determining the Then-Current Market Price, the determination of the Closing
Price by the calculation agent for the ELKS in the event of a Market Disruption
Event, as described in the definition of Closing Price, may be deferred by the
calculation agent for the ELKS for up to five consecutive Trading Days on which
a Market Disruption Event is occurring.



                                       7
<PAGE>   8
         The "Ex-Date" with respect to any dividend, distribution or issuance is
the first date on which the shares of the common stock trade in the regular way
on their principal market without the right to receive this dividend,
distribution or issuance.

         In the event of any of the following "Reorganization Events":

         -     any consolidation or merger of Sun Microsystems, or any surviving
               entity or subsequent surviving entity of Sun Microsystems, with
               or into another entity, other than a merger or consolidation in
               which Sun Microsystems is the continuing corporation and in which
               the common stock outstanding immediately before the merger or
               consolidation is not exchanged for cash, securities or other
               property of Sun Microsystems or another issuer,

         -     any sale, transfer, lease or conveyance to another corporation of
               the property of Sun Microsystems or any successor as an entirety
               or substantially as an entirety,

         -     any statutory exchange of securities of Sun Microsystems or any
               successor of Sun Microsystems with another issuer, other than in
               connection with a merger or acquisition, or

         -     any liquidation, dissolution or winding up of Sun Microsystems or
               any successor of Sun Microsystems,

each Holder of the ELKS will have the right to receive cash in an amount per $10
principal amount of ELKS equal to the Exchange Rate multiplied by the
Transaction Value (as defined below).

         The "Transaction Value" will be the sum of:

         (1)   for any cash received in a Reorganization Event, the amount of
               cash received per share of common stock,

         (2)   for any property other than cash or Marketable Securities
               received in a Reorganization Event, an amount equal to the market
               value on the date the Reorganization Event is consummated of that
               property received per share of common stock, as determined by a
               nationally recognized independent investment banking firm
               retained for this purpose by the Company, whose determination
               will be final, and

         (3)   for any Marketable Securities received in a Reorganization Event,
               an amount equal to the Closing Price per share of these
               Marketable Securities on the Trading Day immediately prior to the
               maturity date or Exchange Date multiplied by the number of these
               Marketable Securities received for each share of common stock.

         "Marketable Securities" are any perpetual equity securities or debt
securities with a stated maturity after the maturity date, in each case that are
listed on a U.S. national securities exchange or reported by the Nasdaq Stock
Market. The number of shares of any equity securities


                                       8
<PAGE>   9
constituting Marketable Securities included in the calculation of Transaction
Value pursuant to clause (3) above will be adjusted if any event occurs with
respect to the Marketable Securities or the issuer of the Marketable Securities
between the time of the Reorganization Event and maturity that would have
required an adjustment as described above, had it occurred with respect to the
Sun Microsystems common stock or Sun Microsystems. Adjustment for these
subsequent events will be as nearly equivalent as practicable to the adjustments
described above.

GENERAL

         This Note is one of a duly authorized issue of Debt Securities of the
Company, issued and to be issued in one or more series under a Senior Debt
Indenture, dated as of October 27, 1993, as supplemented by a First Supplemental
Indenture, dated as of November 28, 1997, a Second Supplemental Indenture, dated
as of July 1, 1999, and as further supplemented from time to time (the
"Indenture"), between the Company and The Bank of New York, as Trustee (the
"Trustee", which term includes any successor trustee under the Indenture), to
which Indenture reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the ELKS, and the terms upon which the ELKS are,
and are to be, authenticated and delivered.

         If an Event of Default with respect to the ELKS shall have occurred and
be continuing, the principal of the ELKS may be declared due and payable in the
manner and with the effect provided in the Indenture. In such case, the amount
declared due and payable upon any acceleration permitted by the Indenture will
be determined by the calculation agent for the ELKS and will be equal to, with
respect to this Note, the Maturity Payment calculated as though the Stated
Maturity Date of this Note were the date of early repayment. In case of default
at Maturity of this Note, this Note shall bear interest, payable upon demand of
the beneficial owners of this Note in accordance with the terms of the ELKS,
from and after Maturity through the date when payment of such amount has been
made or duly provided for, at the rate of [ ]% per annum on the unpaid amount
