                            REEBOK INTERNATIONAL LTD.
                          RESTRICTED STOCK CERTIFICATE
                  GRANTED UNDER THE 1994 EQUITY INCENTIVE PLAN

         This Restricted Stock Certificate (the "Certificate") evidences
Restricted Shares (defined below) granted by Reebok International Ltd., a
Massachusetts corporation ("Reebok" or the "Company"), to PAUL DUNCAN, an
employee of the Company or its subsidiaries (the "Employee"), pursuant to the
Company's 1994 Equity Incentive Plan (the "Plan").

         1. GRANT OF RESTRICTED STOCK. This Certificate evidences the grant by
the Company on FEBRUARY 2, 2000 to the Employee of a total of 50,000 shares of
Common Stock of the Company (the "Restricted Shares"), at the per share price of
$7.125, subject to the restrictions and other conditions set forth herein. The
Restricted Shares shall be subject to forfeiture by the Employee, and may not be
sold, assigned, transferred, pledged, encumbered or otherwise disposed of, until
they have vested in accordance with the following vesting schedule, and subject
to Section 6:

         (a)      One-third of the Restricted Shares will vest on the earlier
                  of: (i) the April 1 following the fiscal year in which the
                  Company's Earnings Per Share as set forth in the Company's
                  Audited Financial Statements included in its Annual Report on
                  Form 10-K ("EPS") is $1.50 or more; and (ii) the fifth trading
                  day in any ten trading day period on which the Company's stock
                  closes at $18.00 per share or more; and

         (b)      An additional one-third of the Restricted Shares will vest on
                  the earlier of: (i) the April 1 following the fiscal year in
                  which the Company's EPS is $2.25 or more; and (ii) the fifth
                  trading day in any ten trading day period on which the
                  Company's stock closes at $27.00 per share or more; and

         (c)      The remaining one-third of the Restricted Shares will vest on
                  the earlier of: (i) the April 1 following the fiscal year in
                  which the Company's EPS is $3.00 or more; and (ii) the fifth
                  trading day in any ten trading day period on which the
                  Company's stock closes at $36.00 per share or more;

         (d)      All Restricted Shares that have not previously vested pursuant
                  to the immediately preceding clauses (a), (b) and (c) will
                  vest on July 31, 2001.

The number of Restricted Shares to be vested on any vesting date hereunder shall
be adjusted appropriately by the Compensation Committee of the Board of
Directors (the "Committee"), or its designees, to reflect any additional
Restricted Shares (if applicable) received pursuant to Section 7 hereof. For
purposes of this section, "trading day" shall be defined as any day in which
shares are traded on the NYSE.

          2. STOCK CERTIFICATES. Prior to the vesting of any Restricted Shares,
the stock certificate(s) representing those Restricted Shares that have not yet
vested shall be held for the Employee by the Company or by a custodian
designated by the Company. The Employee shall receive all dividends (other than
stock dividends which shall be held in accordance with the terms of Section 7
below), stockholder communications and proxy materials with regard to the
Restricted Shares. Any certificate or certificates for Restricted Shares which
are forfeited in accordance with the provisions hereof shall be returned to the
Company. The Employee shall be entitled to any dividends or other distributions
(other than stock dividends which shall be held in accordance with the terms of
Section 7 below) attributable to forfeited Restricted Shares which are paid
after forfeiture of such Shares with respect to a record date prior to
forfeiture and shall have voting rights.

                                       1
<PAGE>   2
         On each date on which a portion of the Restricted Shares vest, as set
forth in Section 1 above, the Employee shall be entitled to delivery of the
certificate(s) representing those Restricted Shares which have vested, subject
to the other provisions hereof, and the Restricted Shares represented thereby
shall cease to be subject to forfeiture.

          3. DELIVERY OF RESTRICTED SHARES. The Employee shall cooperate to
effect delivery of any Restricted Shares which have vested in accordance with
the terms of all federal and state laws and regulations as interpreted by
counsel for the Company. Without in any way limiting the generality of the
foregoing, the Company may require that the certificate(s) representing
Restricted Shares bear a legend restricting the transfer thereof except upon
compliance with the conditions stated herein and the federal and state
securities laws and that the Employee, as a condition for delivery, make such
representation or agreement, if any, as may be required in the opinion of such
counsel to avoid violation of any laws or regulations, including without
limitation, the registration or other provisions of the Securities Act of 1933.

         4. WITHHOLDING. No Restricted Shares will be delivered to the Employee
unless and until the Employee remits to the Company an amount sufficient to
satisfy any federal, state or local withholding tax requirements (including,
without limitation, any amount required under FICA), or makes other arrangements
satisfactory to the Company with regard to the payment of such taxes.

         5. NONTRANSFERABILITY OF GRANT. No Restricted Shares, nor any interest
therein, may be transferred by the Employee (by sale, pledge, gift or otherwise)
prior to the vesting of such Shares and the Restricted Shares granted hereunder
shall be delivered only to the Employee, or in the case of death, the Employee's
estate. Notwithstanding the foregoing, if the Employee is incapacitated, the
Restricted Shares may be delivered to the person or persons legally appointed to
represent the Employee, provided that the Company is satisfied as to the
authority of such legal representative.

         6. TERMINATION OF EMPLOYMENT. Unless other agreements apply, if the
Employee's employment with the Company or its subsidiaries terminates for cause,
or a voluntary resignation or retirement before July 31, 2001, all Restricted
Shares which have not vested prior to the date of such separation of employment
shall be deemed to have been forfeited by the Employee and shall be returned to
the Company. In the event of a Change of Control (as defined in Section 8), the
Restricted Shares shall vest notwithstanding any termination of active
employment. For purposes herein, employment shall not be considered terminated:
(i) in the case of sick leave or other bona fide leave of absence approved for
purposes of the Plan by the Committee, so long as the Employee's right to
reemployment is guaranteed either by statute or by contract, or (ii) in the case
of a transfer of employment between the Company and a subsidiary or between
subsidiaries, or (iii) if the Company requests that the Employee leave prior to
July 31, 2001 for reasons other than for cause.

         7. ADDITIONAL RESTRICTED SHARES. Any shares of Common Stock of the
Company or other securities which the Employee may receive or be entitled to
receive as a result of the ownership of the Restricted Shares, whether the same
are issued as a result of a share split, stock dividend, recapitalization, or
other subdivision or consolidation of Shares effected without receipt of
consideration by the Company or the result of the merger or consolidation of the
Company or sale of assets of the Company, shall be treated for all purposes as
Restricted Shares hereunder and shall be held by the Company pursuant to Section
2 hereof until such Restricted Shares have vested.

         8. CHANGE OF CONTROL. If a Change in Control of Reebok occurs, the
Restricted Shares shall be accelerated such that all of the Restricted Shares
shall vest effective upon the date of such Change of Control. A Change of
Control will occur for purposes of this Certificate if: (i) any Person who does
not

                                       2
<PAGE>   3
currently own directly or indirectly 5% or more of the combined voting power
of the Company's outstanding securities becomes the "beneficial owner" (as
defined in Rule 13d-3 under the Act) of securities of the Company representing
more than 30% (or, if higher, the aggregate percentage of the combined voting
power of the Company's then-outstanding securities held by or for the benefit of
Paul Fireman and his family) of the combined voting power of the Company's
then-outstanding securities, (ii) there is a change of control of the Company of
a kind which would be required to be reported under Item 6(e) of Schedule 14A of
Regulation 14A promulgated under the Act (or a similar item in a similar
schedule or form), whether or not the Company is then subject to such reporting
requirement, (iii) the Company is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board in office immediately prior to such transaction or event
constitute less than a majority of the Board thereafter, or (iv) individuals
who, at the date hereof, constitute the Board (the "Continuing Directors") cease
for any reason to constitute a majority thereof, provided, however, that any
director who is not in office at the date hereof but whose election by the Board
or whose nomination for election by the Company's shareholders was approved by a
vote of at least two-thirds of the directors then still in office who either
were directors at the date hereof or whose election or nomination for election
was previously so approved shall be deemed to be a Continuing Director for
purposes of this Certificate.

         Notwithstanding the foregoing provisions of the above paragraph, a
Change of Control will not be deemed to have occurred if the initiation of any
of the events described in the preceding paragraph is by or with the concurrence
of the Company (acting by its Continuing Directors), nor shall a Change of
Control be deemed to have occurred solely because of: (i) the acquisition of
securities of the Company (or any reporting requirement under the Act relating
thereto) by an employment benefit plan maintained by the Company for its
employees, or (ii) the occurrence of a leveraged buy-out or re-capitalization of
the Company in which Executive participates as an equity investor so long as the
Employee's Restricted Stock was converted to equity securities on a basis no
less favorable than that generally adopted for other senior executives of the
Company.

         9. PROVISIONS OF THE PLAN. The grant is subject to the provisions of
the Plan, a copy of which is furnished to the Employee with this Certificate.

         IN WITNESS WHEREOF, the Company has caused this grant to be executed
under its corporate seal by its duly authorized officer. This grant shall take
effect as a sealed instrument.

                                 PROMISSORY NOTE

$166,546.88                                            STOUGHTON, MASSACHUSETTS
                                                       February 2, 2000

         FOR VALUE RECEIVED, the undersigned PAUL DUNCAN (hereinafter the
"Employee" or the "Borrower") hereby promises to pay to the order of Reebok
International Ltd., 100 Technology Center Drive, Stoughton, Massachusetts 02072
(hereinafter called "Reebok" or the "Company") the principal amount of ONE
HUNDRED SIXTY-SIX THOUSAND FIVE HUNDRED FORTY-SIX DOLLARS AND EIGHTY-EIGHT CENTS
($166,546.88) (the "Original Principal Amount"), together with interest on the
outstanding principal balance at a fixed rate per annum of 6.21% (but in no
event higher than the maximum permitted by law), in the manner set forth herein.
This Promissory Note (the "Note") and all principal and interest thereon matures
on July 31, 2001, or earlier, as set forth below.

         This Note and the indebtedness evidenced hereby are being provided
pursuant to the terms of the Restricted Stock Certificate dated February 2, 2000
(the "Certificate") and the Section 83(b) of the Internal Revenue Code election
between Employee and Reebok (the "Section 83(b) Election"). The proceeds of the
loan may be used only for the purpose of paying the federal and state income
taxes due as a result of Employee's making the Section 83(b) Election with
respect to the Certificate.

         Except as noted below, Employee shall pay to Reebok the principal
amount referenced above and the applicable interest in full on July 31, 2001.
This Note may be called and required to be paid in full if: (i) you fail to make
payments when due, or (ii) your employment with Reebok is terminated for cause,
or (iii) you voluntarily resign prior to February 2, 2001. The Restricted Shares
granted to you by the Certificate are hereby pledged as collateral for this
Note.

         Reebok shall have the right to set off any amounts that Employee owes
Reebok hereunder against any monies that Reebok or any of its subsidiaries may
owe to Employee, of any nature whatsoever, including without limitation, any
compensation (including bonus amounts) and any severance owed or any other
benefit owed to or held as an employee of Reebok or any of its subsidiaries, and
Employee hereby agrees to and authorizes any such setoff.

         If payment of the principal on this Note is not paid in accordance with
the terms aforementioned, then this Note shall be deemed to be in default and if
suit is brought to collect this Note, Reebok shall be entitled to collect, in
addition to any principal outstanding, all reasonable costs and expenses to
include, but not necessarily be limited to, reasonable attorneys' fees and
expenses.

         Presentment, notice of dishonor and protest are hereby waived by
Borrower. This Note shall be binding upon Borrower and his or her heirs,
executors, administrators, and legal representatives. No delay or omission on
the part of the Reebok in exercising any rights hereunder shall operate as a
waiver of such rights or of any other right of Reebok, nor shall any

                                       1
<PAGE>   2
delay, omission or waiver on any one occasion be deemed as a bar to, or waiver
of, the same or any other right on any future occasion. This Note may not be
changed or terminated orally. Borrower shall have the right to prepay the
principal and any accrued interest on this Note, in whole or in part, at any
time or times, without penalty.

         All rights and obligations hereunder shall be governed by, and
construed and enforced in accordance with, the substantive laws of the
Commonwealth of Massachusetts, and this Note is executed as, and shall have
effect of, a sealed instrument. If any provision of this transaction is
inconsistent with the laws and statutes of the Commonwealth of Massachusetts,
the rest of the transaction shall not be affected, and that part that is not in
accord with the said laws shall be adjusted to so comply.

         IN WITNESS WHEREOF, the undersigned has executed this Note as an
instrument under seal as of the date first set forth above.

                                           /s/ Paul Duncan
