    3.1 Administration. The Plan shall be administered by the Committee in
accordance with this Article 3. Subject to the terms and conditions of the Plan,
the Committee or the Section 162(m) Subcommittee as applicable shall have the
sole discretionary authority:

        (a) to authorize the granting of Restricted Stock Awards;

        (b) to select any Reporting Persons who are to be granted Restricted
    Stock under the Plan and to determine, subject to the limitations provided
    in Section 6.1 hereof, the number of shares of Restricted Stock to be
    granted to each Reporting Person;

        (c) to construe and interpret the Plan;

        (d) to establish and modify administrative rules for the Plan;

        (e) to impose such conditions and restrictions with respect to the
    Restricted Stock Awards, not inconsistent with the terms of the Plan, as it

        (f) to execute or cause to be executed Award Agreements; and

    contemplated hereunder.

    Action taken or not taken by the Compensation Committee on one or more
occasions shall be without obligation to take or not take such action on any
other occasion(s).

    The Committee may delegate to one or more Persons any of its powers, other
than its power to authorize the granting of Awards, hereinbefore or hereinafter
provided or conferred, or designate one or more Persons to do or perform those
matters to be done or performed by the Compensation Committee, including
administration of the Plan. Notwithstanding the foregoing, the Committee may not
delegate a power if the delegation of such power would cause the Plan to fail to
satisfy the plan administration requirements set forth in Rule 16b-3(c)
promulgated under the Exchange Act or section 162(m) of the Code and the
regulations promulgated thereunder. Any Person or Persons delegated or
designated by the Committee shall be subject to the same obligations and
requirements imposed on the Committee and its members under the Plan.

expenses of administering the Plan.

indemnification and reimbursement from the Corporation for any action or any
failure to act in connection with services performed by or on behalf of the
Committee for the benefit of the Corporation to the fullest extent provided or
permitted by the Corporation's Articles of Incorporation and by any insurance
policy or other agreement intended for the benefit of the Committee as a
committee of the Board of Directors or otherwise, or by any applicable law.

                                   ARTICLE 4

                   SHARES OF COMMON STOCK SUBJECT TO THE PLAN

    4.1 Shares Subject to the Plan. The Restricted Stock to be made the subject
of Awards granted under the Plan shall be shares of the Corporation's authorized
but unissued or reacquired Class B Common Stock. Subject to adjustment as
provided in Section 8.3 hereof, the aggregate number of shares of Class B Common
Stock that may be issued by the Corporation under the Plan is 2,000,000 shares
of Class B Common Stock. The aggregate number of shares of Restricted Stock
outstanding at any time shall not exceed the relevant number of shares of Class
B Common Stock remaining available for issuance under the Plan.

    4.2 Restricted Stock Subject to Forfeited or Terminated Awards. In the event
that any Restricted Stock with respect to an outstanding Award is forfeited,
surrendered, expires or is terminated for any reason before the Period of
Restriction has been satisfied, all shares of Restricted Stock allocable to the
forfeited or terminated portion of such Award shall again be available for
Awards subsequently granted under the Plan.

    4.3 Exchange of Options for Restricted Stock. Employees who were previously
granted certain Options under the Stock Option Plan may have a choice to
exchange those Options for Restricted Stock under the Plan pursuant to a
pre-determined conversion ratio as approved by the Compensation Committee (the
'Exchange Offer'). Options eligible for the exchange ('Eligible Options') will
also be determined by the Compensation Committee prior to the Date of Grant.
Only those Optionees who satisfy the following criteria are eligible for the
exchange:

        (a) Optionee must be actively employed by the Corporation or a
    Subsidiary (or on an approved leave of absence) on the Date of Grant and
    must not either have given notice of termination of employment or received
    notice of termination of employment as of the Date of Grant; and

        (b) Optionee must hold a certain number of Eligible Options which are
    unexercised and outstanding (i.e., have not expired). The number shall be
    determined by the Compensation Committee.

    An Optionee who satisfies the criteria under this Section 4.3 may have a
choice to exchange all Eligible Options; no partial exchange is permitted. The
number of Eligible Options and the number of shares of Restricted Stock granted
in exchange for cancellation of the Eligible Options will be set forth in the
Award Agreement for each Participant. Any Options which are exchanged for
Restricted Stock pursuant to this Section 4.3 shall be cancelled. Restricted
Stock granted in exchange for the cancelled Options shall be subject to all of
the terms and conditions of this Plan.

                                   ARTICLE 5

                                 PARTICIPATION

    Plan Participants shall be such Employees as the Compensation Committee may
select (who may include officers). In making such selections, the Committee may
take into account the nature of the services rendered by such Employees, their
present and potential contributions to the Corporation's success, and such other
factors as the Committee in its discretion shall deem relevant.

                                   ARTICLE 6

                                RESTRICTED STOCK

    6.1 Grant of Restricted Stock. The Compensation Committee will cause the
Corporation to issue Restricted Stock under the Plan in connection with an
Exchange Offer described in Article 4. The Compensation Committee may also from
time to time cause the Corporation to issue additional shares of Restricted
Stock under the Plan, subject to such restrictions, conditions and other terms
as the Compensation Committee may determine in addition to those set forth
herein. The maximum aggregate number of shares of Restricted Stock which may be
granted to any one Employee during a Fiscal Year shall be limited to 200,000
shares. For purposes of calculating the maximum number of shares of

                                       5




<Page>

Restricted Stock granted in any Fiscal Year to an Employee who is subject to
Code Section 162(m), any shares that are granted and subsequently cancelled or
surrendered during such Fiscal Year shall continue to be counted against the
maximum number of shares which may be granted to such Employee pursuant to the
Plan during such Fiscal Year. Notwithstanding the foregoing, to the extent an
adjustment is made to the Common Stock to reflect a change in the corporate
capitalization of the Corporation, the additional shares of Restricted Stock, if
any, shall not be counted against the maximum number of shares which may be
granted to the Participant.

    6.2 Restrictions. The Restricted Stock issued in connection with an Exchange
Offer shall be subject to the vesting schedule under Section 7.3 or such other
vesting schedule as the Compensation Committee determines. Restricted Stock
grants other than those made pursuant to an Exchange Offer, if any, will also be
subject to vesting under Section 7.3 unless the Compensation Committee
establishes a different Period of Restriction applicable to such Restricted
Stock. Each grant of Restricted Stock may be subject to a different Period of
Restriction as specified in the Award Agreement. The Compensation Committee may,
in its sole discretion, at the time a grant is made, prescribe restrictions in
addition to or other than the expiration of the Period of Restriction, including
the satisfaction of corporate or individual performance objectives, which shall
be applicable to all or any portion of the Restricted Stock. Such restrictions
shall be set forth in the Participant's Award Agreement.

    Except with respect to grants of Restricted Stock intended to qualify as
performance based compensation for purposes of Section 162(m) of the Code, the
Compensation Committee may also, in its sole discretion, shorten or terminate
the Period of Restriction or waive any other restrictions applicable to all or a
portion of such Restricted Stock. None of the Restricted Stock may be sold,
transferred, assigned, pledged or otherwise encumbered or disposed of prior to
the date on which such Restricted Stock vests in accordance with Section 7.3.

    6.3 Restricted Stock Share Certificates. Restricted Stock awarded to a
Participant may be held under the Participant's name in a book entry account
maintained by or on behalf of the Corporation. Upon vesting of the Restricted
Stock, the Corporation will establish procedures regarding the delivery of share
certificates or the transfer of shares in book entry form.

    6.4 Voting and Dividend Rights. Except as otherwise determined by the
Committee either at the time Restricted Stock is awarded or at any time
thereafter prior to the lapse of the restrictions, holders of Restricted Stock
shall have the right to vote such shares and the right to receive any dividends
with respect to such shares, whether or not the shares of Restricted Stock are
vested. All distributions, if any, received by an Employee with respect to
Restricted Stock as a result of any stock split, stock distributions,
combination of shares, or other similar transaction shall be subject to the
restrictions of the Plan.

                                   ARTICLE 7

                    TERMS AND CONDITIONS OF RESTRICTED STOCK

    7.1 Award Agreements. The terms of the Restricted Stock granted under the
Plan shall be as set forth in a written agreement (an 'Award Agreement') in such
form as the Committee shall from time to time determine. Each Award Agreement
shall comply with and be subject to the terms and conditions of the Plan and
such other terms and conditions as the Committee may deem appropriate. No Person
shall have any rights under the Plan unless and until the Corporation and the
Participant have executed an Award Agreement setting forth the grant and the
terms and conditions of the Restricted Stock.

    7.2 Plan Provisions Control Terms. The terms of the Plan shall govern all
Restricted Stock granted under the Plan. In the event that any provision of an
Award Agreement shall conflict with any term in the Plan as constituted on the
Date of Grant, the term in the Plan constituted on the Date of Grant of such
Option shall control.

    7.3 Vesting. Except in the case of the death, Disability, or Retirement of a
Participant, and subject to the provisions of Section 7.4 hereof, the Restricted
Stock Granted under the Plan will vest in accordance with the following
schedule:

                                       6

COMPLETED YEARS OF EMPLOYMENT      CUMULATIVE
     FROM DATE OF GRANT        VESTING PERCENTAGE
     ------------------        ------------------
                            
          1                            25%
          2                            50%
          3                            75%
          4 or more                   100%
</Table>

    Except as provided in this Section 7.3, in the event a Participant
terminates employment prior to 100% vesting, any shares of Restricted Stock
which are not vested shall be forfeited immediately and permanently. A
Participant shall be 100% vested in his Restricted Stock in the event he
terminates employment by reason of death, Disability, or Retirement, or in the
event of a Change in Control as described in Section 7.4.

    For purposes of this Section 7.3, account shall be taken of any adjustments
made to the shares of Restricted Stock as described in Section 8.3 hereof after
the Date of Grant of the Restricted Stock, such that the number of shares of
Restricted Stock with respect to which a Participant is vested shall be
redetermined at the time of an adjustment.

    7.4 Acceleration of Vesting.

        (a) Notwithstanding anything to the contrary in the Plan, including
    Sections 7.3, the Compensation Committee, in its discretion, may accelerate,
    in whole or in part the vesting schedule applicable to a grant of Restricted
    Stock.

        (b) In the event of a Change in Control (as defined in the Sotheby's
    Holdings, Inc. 1997 Stock Option Plan), Restricted Stock granted under the
    Plan shall become 100% vested on the date of the Change in Control.

    7.5 Taxes and Withholding. When a Participant incurs tax liability in
connection with the lapse of a restriction which tax liability is subject to tax
withholding under applicable tax laws, and the Participant is obligated to pay
an amount required to be withheld under applicable tax laws, the withholding tax
obligation will be satisfied by withholding from shares to be issued upon lapse
of such restriction that number of shares of Common Stock having a Fair Market
Value equal to the minimum amount required to be withheld (but in no event any
more than the minimum amount required to be withheld). The Corporation will
establish the procedures for selling shares needed to satisfy the tax
withholding liability, which procedures may include selling shares on the open
market or the Corporation's purchase of such shares or such other procedures as
the Corporation deems desirable. The Participant also has the option to make
payment in cash in United States dollars in lieu of the share withholding
described above pursuant to procedures established by the Corporation. The
amount of any such withholding shall be determined by the Corporation.

    7.6 Surrender of Restricted Stock. Any Restricted Stock granted under the
Plan may be surrendered to the Corporation for cancellation on such terms as the
Committee and the Participant agree.

    7.7 Restrictions on Ownership of Class B Common Stock; Incorporation by
Reference of Articles of Incorporation. Ownership of Class B Common Stock is
subject to all of the restrictions contained in the Articles of Incorporation,
including the automatic conversion of Class B Common Stock to Class A Common
Stock. The relevant provisions of the Articles of Incorporation are hereby
incorporated by reference.

    7.8 Issuance of Class A Common Stock. This Section 7.8 applies if at any
time that shares of any class of the Corporation's capital stock are listed on a
national securities exchange, the rules of such exchange or of any governmental
agency of the United States of America require the delisting of such shares if
the Corporation issues shares of Class B Common Stock. In that event, the
Corporation shall deliver the same number of shares of Class A Common Stock as
the number of shares of Class B Common Stock that is the subject of the
Restricted Stock.

           AMENDMENT AND TERMINATION OF THE PLAN; REORGANIZATIONS AND
                      RECAPITALIZATIONS OF THE CORPORATION

    8.1 Amendment of the Plan. The Compensation Committee may from time to time
suspend or discontinue the Plan or revise or amend the Plan in any respect
whatsoever; provided, however, that to the extent necessary and desirable to
comply with Rule 16b-3 under the Exchange Act and with section 162(m) of the
Code (or any other applicable law or regulation, including the requirements of
any stock exchange on which the Common Stock is listed or quoted), shareholder
approval of any plan amendment shall be obtained in such a manner and to such a
degree as is required by the applicable law or regulation. In the event of a
revision or amendment to the Plan, all outstanding Restricted Stock shall be
adjusted to be consistent with the terms and provisions of the Plan, as revised
or amended, and in such manner as the Compensation Committee may deem equitable
or as may be required pursuant to applicable law; provided, however, that except
with the written consent of a Participant or as otherwise specifically provided
herein with respect to a replacement plan, no amendment, suspension, termination
or modification of the Plan shall alter or impair the rights of a Participant
under any Award previously granted under the Plan.

    8.2 Termination of the Plan. The Compensation Committee, with the approval
or at the direction of the Board of Directors, and the Board of Directors shall
have the right and power to terminate the Plan at any time, and no Restricted
Stock shall be granted under the Plan after the termination of the Plan. The
termination of the Plan shall not have any other effect, and any outstanding
Restricted Stock shall be subject to the same terms and conditions, as provided
in Article 7 hereof, that would have applied to such Restricted Stock if the
Plan had not been terminated.

    8.3 Reorganizations and Recapitalizations of the Corporation.

        (a) The existence of this Plan and Restricted Stock granted hereunder
    shall not affect in any way the right or power of the Corporation or its
    shareholders to make or authorize any or all adjustments, recapitalizations,
    reorganizations or other changes in the Corporation's capital structure or
    its business, or any merger or consolidation of the Corporation, or any
    issue of bonds, debentures, preferred or prior preference stocks ahead of or
    affecting the shares or the rights thereof, or the dissolution or
    liquidation of the Corporation, or any sale or transfer of all or any part
    of its assets or business, or any other corporate act or proceeding, whether
    of a similar character or otherwise.

        (b) The issue by the Corporation of shares of stock of any class, or
    securities convertible into shares of stock of any class, for cash or
    property, or for labor or services, either upon direct sale or upon exercise
    of rights or warrants to subscribe therefor, or upon conversion of shares or
    obligations of the Corporation convertible into such shares or other
    securities, shall not affect, and no adjustment by reason thereof shall be
    made with respect to, the number of shares subject to Restricted Stock
    granted hereunder.

                                   ARTICLE 9

                   COMPLIANCE WITH OTHER LAWS AND REGULATIONS

    9.1 Registration or Qualification of Securities. The Plan and the grant of
Restricted Stock under the Plan shall be subject to all applicable federal and
state laws, rules, and regulations and to such approvals by any government or
regulatory agency as may be required. Each share of Restricted Stock shall be
subject to the requirement that if at any time the Compensation Committee shall
determine, in its discretion, that the listing, registration or qualification of
the shares covered thereby under any securities exchange or under any state or
federal law or the consent or approval of any governmental regulatory body is
necessary or desirable as a condition of, or in connection with, the granting of
such Restricted Stock, the Restricted Stock shall comply with any registration,
qualification, consent or approval requirements as imposed by the Compensation
Committee.

    9.2 Representation. The Compensation Committee may require that any Person
who is granted Restricted Stock under the Plan represent and agree in writing
that if the shares of Common Stock

                                       8




<Page>

made subject to the Restricted Stock are issuable under an exemption from
registration requirements, the shares will be 'restricted' securities which may
be resold only in compliance with the applicable securities laws, and that such
Person is acquiring the shares issued for investment purposes and not with a
view toward distribution.

    9.3 Exchange of Certificates. If, in the opinion of the Corporation and its
counsel, any legend placed on a stock certificate representing shares of Class B
Common Stock sold under the Plan is no longer required, the holder of such
certificate shall be entitled to exchange such certificate for a certificate
representing the same number of such shares but lacking such legend.

                                   ARTICLE 10

                            RESTRICTIONS ON TRANSFER

    A Participant's rights and interests under the Plan may not be assigned or
transferred other than by will or the laws of descent and distribution, and
during the lifetime of a Participant, only the Participant personally (or the
Participant's personal representative) may exercise his rights under the Plan.
No purported assignment, pledge or transfer of Restricted Stock granted under
the Plan, whether voluntary or involuntary, by operation of law or otherwise,
shall vest in the purported transferee or assignee any interest or right therein
whatsoever but immediately upon any such purported assignment or transfer, or
any attempt to make the same, such Restricted Stock thereunder shall terminate
and become of no further effect.

                                   ARTICLE 11

                               GENERAL PROVISIONS

    11.1 No Right to Continued Employment. No Employee or any other Person shall
have any claim or right to be issued Restricted Stock under the Plan. Neither
the adoption and maintenance of the Plan nor the granting of Restricted Stock
pursuant to the Plan shall be deemed to constitute a contract of employment
between the Corporation and any Employee or to be a condition of the employment
of any Person. The Plan and any Restricted Stock granted under the Plan shall
not confer upon any Participant any right with respect to continued employment
by the Corporation, nor shall they interfere in any way with the right of the
Corporation to terminate the employment of any Participant at any time, and for
any reason, with or without cause, it being acknowledged, unless expressly
provided otherwise in writing, that the employment of a Participant is and
continues to be 'at will.'

    11.2 Beneficiaries or Representatives of a Participant. The Compensation
Committee's determination of death or Disability and of the right of any Person
other than a Participant under the Plan shall be conclusive. The Compensation
Committee, in its discretion, may require from any Person, other than an a
Participant such security and indemnity as the Compensation Committee, in its
discretion, deems necessary or advisable.

    11.3 Elimination of Fractional Shares. If under any provision of the Plan
that requires a computation of the number of shares of Restricted Stock the
number so computed is not a whole number of shares of Restricted Stock, such
number of shares of Restricted Stock shall be rounded down to the next whole
number.

    11.4 Inspection of Records. Copies of the Plan, records reflecting each
Participant's Awards, and any other documents and records that a Participant is
entitled by law to inspect shall be open to inspection by the Participant and
his duly authorized representative(s) at the office of the Corporation at any
reasonable business hour.

    11.5 Word Meanings. The words such as 'herein,' 'hereinafter,' 'hereof,' and
'hereunder' refer to this Plan as a whole and not merely to a subdivision in
which such words appear unless the context otherwise requires.

    11.6 Section Titles. Section titles are for descriptive purposes only and
shall not control or alter the meaning of the Plan as set forth in the text.

                                       9

    11.7 Severability. Whenever possible, each provision in the Plan and all
Restricted Stock granted under the Plan shall be interpreted in such a manner as
to be effective and valid under applicable law, but if any provision of the Plan
or any Restricted Stock at any time granted under the Plan shall be held to be
prohibited or invalid under applicable law, then, (i) such provision shall be
deemed amended to accomplish the objectives of the provision as originally
written to the fullest extent permitted by law, and (ii) all other provisions of
the Plan and all other Restricted Stock at any time granted under the Plan shall
remain in full force and effect.

    11.8 Compliance with Section 16(b) of the Securities Exchange Act. With
respect to Reporting Persons, transactions under this Plan are intended to
comply with all applicable conditions of Rule 16b-3 or its successors under the
Exchange Act and in all events the Plan shall be construed in accordance with
Rule 16b-3. To the extent any provision of the Plan or action by the
Compensation Committee fails to so comply, it shall be deemed null and void to
the extent permitted by law and deemed advisable by the Compensation Committee.
The Compensation Committee, in its absolute discretion, may bifurcate the Plan
so as to restrict, limit or condition the use of any provision of the Plan to
participants who are officers or directors of the Corporation, subject to
Section 16 of the Exchange Act without so restricting, limiting or conditioning
the Plan with respect to other participants.

    11.9 Compliance with Code Section 162(m). This Plan is intended to comply
with all applicable provisions of section 162(m) of the Code. To the extent any
provision of the Plan or action by the Compensation Committee fails to so
comply, it shall be deemed null and void to the extent permitted by law and
deemed advisable by the Compensation Committee.

    11.10 Strict Construction. No rule of strict construction shall be implied
against the Compensation Committee, the Corporation or any other Person in the
interpretation of any of the terms of the Plan, any Restricted Stock granted
under the Plan or any rule or procedure established by the Compensation
Committee.

    11.11 Choice of Law. All determinations made and actions taken pursuant to
the Plan shall be governed by the internal laws of the State of Michigan and
construed in accordance therewith.

    To record the adoption of the Plan, the Corporation has caused the execution
hereof as of this 29th day of April, 2003.
