            AMENDED AND RESTATED 1997 STOCK OPTION AND INCENTIVE PLAN

                                 APRIL 27, 2004

SECTION 1.  GENERAL PURPOSE OF THE PLAN; DEFINITIONS

     The name of the plan is the Affiliated Managers Group, Inc. Amended and
Restated 1997 Stock Option and Incentive Plan (the "Plan"). The purpose of the
Plan is to encourage and enable the officers, employees, Independent Directors
and other key persons (including consultants) of Affiliated Managers Group, Inc.
(the "Company") and its Subsidiaries upon whose judgment, initiative and efforts
the Company largely depends for the successful conduct of its business to
acquire a proprietary interest in the Company. It is anticipated that providing
such persons with a direct stake in the Company's welfare will assure a closer
identification of their interests with those of the Company, thereby stimulating
their efforts on the Company's behalf and strengthening their desire to remain
with the Company.

     The following terms shall be defined as set forth below:

     "ACT" means the Securities Exchange Act of 1934, as amended.

     "ADMINISTRATOR" is defined in Section 2(a).

value of the Stock determined in good faith by the Administrator; provided,
however, that (i) if the Stock is admitted to quotation on the National
Association of Securities Dealers Automated Quotation System ("NASDAQ"), the
Fair Market Value on any given date shall not be less than the average of the
highest bid and lowest asked prices of the Stock reported for such date or, if
no

bid and asked prices were reported for such date, for the last day preceding
such date for which such prices were reported, or (ii) if the Stock is admitted
to trading on a national securities exchange or the NASDAQ National Market
System, the Fair Market Value on any date shall not be less than the closing
price reported for the Stock on such exchange or system for such date or, if no
sales were reported for such date, for the last date preceding the date for such
a sale was reported. Notwithstanding the foregoing, the Fair Market Value on the
first day of the Company's initial public offering of Stock shall be the initial
public price as set forth in the final prospectus for the Company's initial
public offering.

     "INCENTIVE STOCK OPTION" means any Stock Option designated and qualified as
an "incentive stock option" as defined in Section 422 of the Code.

Company if each of the corporations or entities (other than the last corporation
or entity in the unbroken chain) owns stock or other interests possessing 50
percent or more of the economic interest or the total combined voting power of
all classes of stock or other interests in one of the other corporations or
entities in the chain.

SECTION 2.  ADMINISTRATION OF PLAN; ADMINISTRATOR AUTHORITY TO SELECT
            PARTICIPANTS AND DETERMINE AWARDS

     (a)    COMMITTEE. The Plan shall be administered by either the Board or a
committee of not less than two Independent Directors (in either case, the
"Administrator"). Each member of the Committee shall be an "outside director"
within the meaning of Section 162(m) of the Code and the regulations promulgated
thereunder and a "non-employee director" within the meaning of Rule
16b-3(b)(3)(i) promulgated under the Act, or any successor definition under said
rule.

     (b)    POWERS OF ADMINISTRATOR. The Administrator shall have the power and
authority to grant Awards consistent with the terms of the Plan, including the
power and authority:

            (i)     to select the individuals to whom Awards may from time to
time be granted;

                                        2
<Page>

            (ii)    to determine the time or times of grant, and the extent, if
any, of Incentive Stock Options and Non-Qualified Stock Options, or any
combination of the foregoing, granted to any one or more participants;

            (iii)   to determine the number of shares of Stock to be covered by
any Award;

            (iv)    to determine and modify from time to time the terms and
conditions, including restrictions, not inconsistent with the terms of the Plan,
of any Award, which terms and conditions may differ among individual Awards and
participants, and to approve the form of written instruments evidencing the
Awards;

            (v)     to accelerate at any time the exercisability or vesting of
all or any portion of any Award or the lapsing at any time of any restrictions
on transfer of all or any portion of any Award;

            (vi)    subject to the provisions of Section 5(a)(ii), to extend at
any time the period in which Stock Options may be exercised;

            (vii)   to determine at any time whether, to what extent, and under
what circumstances distribution or the receipt of Stock and other amounts
payable with respect to an Award shall be deferred either automatically or at
the election of the participant and whether and to what extent the Company shall
pay or credit amounts constituting interest (at rates determined by the
Administrator) or dividends or deemed dividends on such deferrals; and

          (viii)    at any time to adopt, alter and repeal such rules,
guidelines and practices for administration of the Plan and for its own acts and
proceedings as it shall deem advisable; to interpret the terms and provisions of
the Plan and any Award (including related written instruments); to make all
determinations it deems advisable for the administration of the Plan; to decide
all disputes arising in connection with the Plan; and to otherwise supervise the
administration of the Plan.

     All decisions and interpretations of the Administrator shall be binding on
all persons, including the Company and Plan participants.

     (c)    DELEGATION OF AUTHORITY TO GRANT AWARDS. The Administrator, in its
discretion, may delegate to the Chief Executive Officer of the Company all or
part of the Administrator's authority and duties with respect to the granting of
Awards at Fair Market Value, to individuals who are not subject to the reporting
and other provisions of Section 16 of the Act or Covered Employees. Any such
delegation by the Administrator shall include a limitation as to the amount of
Awards that may be granted during the period of the delegation and shall contain
guidelines as to the determination of the exercise price of any Option, the
conversion ratio or price of other Awards and the vesting criteria. The
Administrator may revoke or amend the terms of a delegation at any time but such
action shall not invalidate any prior actions of the Administrator's delegate or
delegates that were consistent with the terms of the Plan.

                                        3

SECTION 3.  STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION

     (a)    STOCK ISSUABLE. The maximum number of shares of Stock reserved and
available for issuance under the Plan shall be 7,875,000 (which amount gives
effect to the three-for-two stock split declared by the Board in January 2004
and effected by a stock dividend in March 2004). For purposes of this
limitation, the shares of Stock underlying any Awards which are forfeited,
cancelled, reacquired by the Company, satisfied without the issuance of Stock or
otherwise terminated (other than by exercise) shall be added back to the shares
of Stock available for issuance under the Plan. Subject to such overall
limitation, shares of Stock may be issued up to such maximum number pursuant to
any type or types of Award; provided, however, that Stock Options with respect
to no more than 1,050,000 shares (which amount gives effect to the three-for-two
stock split declared by the Board in January 2004 and effected by a stock
dividend in March 2004) of Stock may be granted to any one individual
participant during any one calendar year period. The shares available for
issuance under the Plan may be authorized but unissued shares of Stock or shares
of Stock reacquired by the Company and held in its treasury.

     (b)    CHANGES IN STOCK. If, as a result of any reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other similar change in the Company's capital stock, the outstanding
shares of Stock are increased or decreased or are exchanged for a different
number or kind of shares or other securities of the Company, or additional
shares or new or different shares or other securities of the Company or other
non-cash assets are distributed with respect to such shares of Stock or other
securities, the Administrator shall make an appropriate or proportionate
adjustment in (i) the maximum number of shares reserved for issuance under the
Plan, (ii) the number of Stock Options that can be granted to any one individual
participant, (iii) the number and kind of shares or other securities subject to
any then outstanding Awards under the Plan, and (iv) the price for each share
subject to any then outstanding Stock Options under the Plan, without changing
the aggregate exercise price (i.e., the exercise price multiplied by the number
of Stock Options) as to which such Stock Options remain exercisable. The
adjustment by the Administrator shall be final, binding and conclusive. No
fractional shares of Stock shall be issued under the Plan resulting from any
such adjustment, but the Administrator in its discretion may make a cash payment
in lieu of fractional shares.

     The Administrator may also adjust the number of shares subject to
outstanding Awards and the exercise price and the terms of outstanding Awards to
take into consideration material changes in accounting practices or principles,
extraordinary dividends, acquisitions or dispositions of stock or property or
any other event if it is determined by the Administrator that such adjustment is
appropriate to avoid distortion in the operation of the Plan, provided that no
such adjustment shall be made in the case of an Incentive Stock Option, without
the consent of the participant, if it would constitute a modification, extension
or renewal of the Option within the meaning of Section 424(h) of the Code.

     (c)    MERGERS. In contemplation of and subject to the consummation of a
consolidation or merger or sale of all or substantially all of the assets of the
Company in which outstanding shares of Stock are exchanged for securities, cash
or other property of an unrelated corporation or business entity or in the event
of a liquidation of the Company (in each case, a "Transaction"), the Board, or
the board of directors of any corporation assuming the obligations of the
Company, may, in its discretion, take any one or more of the following actions,
as to outstanding Awards:

                                        4
<Page>

(i) provide that such Awards shall be assumed or equivalent awards shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof), and/or (ii) upon written notice to the participants, provide that all
Awards will terminate immediately prior to the consummation of the Transaction.
In the event that, pursuant to clause (ii) above, Awards will terminate
immediately prior to the consummation of the Transaction, all vested Stock
Options shall be fully settled, in cash or in kind, in an amount equal to the
difference between (A) the consideration payable per share of Stock pursuant to
the business combination (the "Merger Price") times the number of shares of
Stock subject to such outstanding Stock Options (to the extent then exercisable
at prices not in excess of the Merger Price) and (B) the aggregate exercise
price of all such outstanding Stock Options; provided, however, that each
participant shall be permitted, within a specified period determined by the
Administrator prior to the consummation of the Transaction, to exercise all
outstanding Stock Options, including any that are not then exercisable; and,
provided further, that any restrictions on transfer then in effect with respect
to any Stock issued or issuable upon the exercise of outstanding Stock Options
shall lapse and be of no further force or effect, subject, in each case, to the
consummation of the Transaction.

     (d)    SUBSTITUTE AWARDS. The Administrator may grant Awards under the Plan
in substitution for stock and stock based awards held by employees of another
corporation who become employees of the Company or a Subsidiary as the result of
a merger or consolidation of the employing corporation with the Company or a
Subsidiary or the acquisition by the Company or a Subsidiary of property or
stock of the employing corporation. The Administrator may direct that the
substitute awards be granted on such terms and conditions as the Administrator
considers appropriate in the circumstances.

SECTION 4.  ELIGIBILITY

     Participants in the Plan will be such full or part-time officers and other
employees, Independent Directors and key persons of the Company and its
Subsidiaries who are responsible for or contribute to the management, growth or
profitability of the Company and its Subsidiaries as are selected from time to
time by the Administrator in its sole discretion.

SECTION 5.  STOCK OPTIONS

     Any Stock Option granted under the Plan shall be in such form as the
Administrator may from time to time approve.

     Stock Options granted under the Plan may be either Incentive Stock Options
or Non-Qualified Stock Options. Incentive Stock Options may be granted only to
employees of the Company or any Subsidiary that is a "subsidiary corporation"
within the meaning of Section 424(f) of the Code. To the extent that any Option
does not qualify as an Incentive Stock Option, it shall be deemed a
Non-Qualified Stock Option.

     No Incentive Stock Option shall be granted under the Plan after April 14,
2009.

     (a)    GRANT OF STOCK OPTIONS. The Administrator in its discretion may
grant Stock Options to employees, Independent Directors and key persons of the
Company or any Subsidiary. Stock Options granted pursuant to this Section 5(a)
shall be subject to the following

                                        5
<Page>

terms and conditions and shall contain such additional terms and conditions, not
inconsistent with the terms of the Plan, as the Administrator shall deem
desirable.

            (i)     EXERCISE PRICE. The exercise price per share for the Stock
covered by a Stock Option granted pursuant to this Section 5(a) shall be
determined by the Administrator at the time of grant but, except as provided in
the last sentence of this Section 5(a)(i), shall not be less than 100 percent of
the Fair Market Value on the date of grant. If an employee owns or is deemed to
own (by reason of the attribution rules of Section 424(d) of the Code) more than
10 percent of the combined voting power of all classes of stock of the Company
or any parent or subsidiary corporation and an Incentive Stock Option is granted
to such employee, the option price of such Incentive Stock Option shall be not
less than 110 percent of the Fair Market Value on the grant date. If the
Administrator so determines, Stock Options may be granted in lieu of cash
compensation at the participant's election, subject to such terms and conditions
as the Administrator may establish. Stock Options granted in lieu of cash
compensation may have an exercise price less than 100 percent of the Fair Market
Value on the date of grant.

            (ii)    OPTION TERM. The term of each Stock Option shall be fixed by
the Administrator, but no Stock Option shall be exercisable more than seven
years after the date the option is granted. If an employee owns or is deemed to
own (by reason of the attribution rules of Section 424(d) of the Code) more than
10 percent of the combined voting power of all classes of stock of the Company
or any parent or subsidiary corporation and an Incentive Stock Option is granted
to such employee, the term of such option shall be no more than five years from
the date of grant.

            (iii)   EXERCISABILITY; RIGHTS OF A STOCKHOLDER. Stock Options shall
become exercisable at such time or times and any Stock issued or issuable
thereunder shall become free of any restrictions on transfer, whether or not in
installments, as shall be determined by the Administrator at or after the grant
date; provided, however, that Stock Options granted in lieu of compensation
shall be exercisable in full and any Stock issued or issuable thereunder shall
be free of any restrictions on transfer as of the grant date. The Administrator
may at any time accelerate the exercisability of all or any portion of any Stock
Option and the lapsing of any restrictions on transfer on any Stock issued or
issuable thereunder, as the case may be. An optionee shall have the rights of a
stockholder only as to shares acquired upon the exercise of a Stock Option,
subject to any applicable restrictions on transfer on the issued Stock, and not
as to any unexercised Stock Options.

            (iv)    METHOD OF EXERCISE. Stock Options may be exercised in whole
or in part, by giving written notice of exercise to the Company, specifying the
number of shares to be purchased. Payment of the purchase price may be made by
one or more of the following methods to the extent provided in the Option Award
agreement:

                    (A)  In cash, by certified or bank check or other instrument
     acceptable to the Administrator;

                    (B)  Through the delivery (or attestation to the ownership)
     of shares of Stock that are not then subject to restrictions under any
     Company plan and that have been purchased by the optionee on the open
     market or have been beneficially owned by the

                                        6
<Page>

     optionee for at least six months, if permitted by the Administrator in its
     discretion. Such surrendered shares shall be valued at Fair Market Value on
     the exercise date;

                    (C)  By the optionee delivering to the Company a properly
     executed exercise notice together with irrevocable instructions to a broker
     to promptly deliver to the Company cash or a check payable and acceptable
     to the Company for the purchase price; provided that in the event the
     optionee chooses to pay the purchase price as so provided, the optionee and
     the broker shall comply with such procedures and enter into such agreements
     of indemnity and other agreements as the Administrator shall prescribe as a
     condition of such payment procedure; or

                    (D)  By the optionee delivering to the Company a promissory
     note if the Board, upon the advice of counsel, has expressly authorized the
     loan of funds to the optionee for the purpose of enabling or assisting the
     optionee to effect the exercise of his Stock Option; provided that at least
     so much of the exercise price as represents the par value of the Stock
     shall be paid other than with a promissory note.

     Payment instruments will be received subject to collection. The delivery of
     certificates representing the shares of Stock to be purchased pursuant to
     the exercise of a Stock Option will be contingent upon receipt from the
     optionee (or a purchaser acting in his stead in accordance with the
     provisions of the Stock Option) by the Company of the full purchase price
     for such shares and the fulfillment of any other requirements contained in
     the Stock Option or applicable provisions of laws. In the event an optionee
     chooses to pay the purchase price by delivery of previously-owned shares of
     Stock through the attestation method, the number of shares of Stock
     transferred to the optionee upon the exercise of the Stock Option shall be
     net of the number of shares attested to.

            (v)     ANNUAL LIMIT ON INCENTIVE STOCK OPTIONS. To the extent
required for "incentive stock option" treatment under Section 422 of the Code,
the aggregate Fair Market Value (determined as of the time of grant) of the
shares of Stock with respect to which Incentive Stock Options granted under this
Plan and any other plan of the Company or its parent and subsidiary corporations
become exercisable for the first time by an optionee during any calendar year
shall not exceed $100,000. To the extent that any Stock Option exceeds this
limit, it shall constitute a Non-Qualified Stock Option.

     (b)    RELOAD OPTIONS. At the discretion of the Administrator, Options
granted under the Plan may include a "reload" feature pursuant to which an
optionee exercising an option by the delivery of a number of shares of Stock in
accordance with Section 5(a)(iv)(B) hereof would automatically be granted an
additional Option (with an exercise price equal to the Fair Market Value of the
Stock on the date the additional Option is granted and with such other terms as
the Administrator may provide) to purchase that number of shares of Stock equal
to the number delivered to exercise the original Option with an Option term
equal to the remainder of the original Option term unless the Administrator
otherwise determines in the Award agreement for the original Option grant.

     (c)    NON-TRANSFERABILITY OF OPTIONS. No Stock Option shall be
transferable by the optionee otherwise than by will or by the laws of descent
and distribution and all Stock Options

                                        7
<Page>

shall be exercisable, during the optionee's lifetime, only by the optionee.
Notwithstanding the foregoing, the Administrator, in its sole discretion, may
provide in the Award agreement regarding a given Option that the optionee may
transfer, without consideration for the transfer, his Non-Qualified Stock
Options to members of his immediate family, to trusts for the benefit of such
family members, or to partnerships in which such family members are the only
partners, provided that the transferee agrees in writing with the Company to be
bound by all of the terms and conditions of this Plan and the applicable Option.

     (d)    TERMINATION. Except as may otherwise be provided by the
Administrator either in the Award agreement, or subject to Section 8 below, in
writing after the Award agreement is issued, an optionee's rights in all Stock
Options shall automatically terminate upon the participant's termination of
employment (or cessation of business relationship) with the Company and its
Subsidiaries for any reason.

SECTION 6.  TAX WITHHOLDING

     (a)    PAYMENT BY PARTICIPANT. Each participant shall, no later than the
date as of which the value of an Award or of any Stock or other amounts received
thereunder first becomes includable in the gross income of the participant for
Federal income tax purposes, pay to the Company, or make arrangements
satisfactory to the Administrator regarding payment of, any Federal, state, or
local taxes of any kind required by law to be withheld with respect to such
income. The Company and its Subsidiaries shall, to the extent permitted by law,
have the right to deduct any such taxes from any payment of any kind otherwise
due to the participant. The Company's obligation to deliver stock certificates
to any participant is subject to and conditioned on tax obligations being
satisfied by the participant.

     (b)    PAYMENT IN STOCK. Subject to approval by the Administrator, a
participant may elect to have the minimum tax withholding obligation satisfied,
in whole or in part, by (i) authorizing the Company to withhold from shares of
Stock to be issued pursuant to any Award a number of shares with an aggregate
Fair Market Value (as of the date the withholding is effected) that would
satisfy the minimum withholding amount due, or (ii) transferring to the Company
shares of Stock owned by the participant with an aggregate Fair Market Value (as
of the date the withholding is effected) that would satisfy the minimum
withholding amount due.

SECTION 7.  TRANSFER, LEAVE OF ABSENCE, ETC.

     For purposes of the Plan, the following events shall not be deemed a
termination of employment:

     (a)    a transfer to the employment of the Company from a Subsidiary or
from the Company to a Subsidiary, or from one Subsidiary to another; or

     (b)    an approved leave of absence for military service or sickness, or
for any other purpose approved by the Company, if the employee's right to
re-employment is guaranteed either by a statute or by contract or under the
policy pursuant to which the leave of absence was granted or if the
Administrator otherwise so provides in writing.

                                        8
<Page>

SECTION 8.  AMENDMENTS AND TERMINATION

     The Board may, at any time, amend or discontinue the Plan and the
Administrator may, at any time, amend or cancel any outstanding Award for the
purpose of satisfying changes in law or for any other lawful purpose, but no
such action shall adversely affect rights under any outstanding Award without
the holder's consent. If and to the extent determined by the Administrator to be
required by the Code to ensure that Incentive Stock Options granted under the
Plan are qualified under Section 422 of the Code or to ensure that compensation
earned under Stock Options qualifies as performance-based compensation under
Section 162(m) of the Code, if and to the extent intended to so qualify, Plan
amendments shall be subject to approval by the Company stockholders entitled to
vote at a meeting of stockholders. Except as provided in Section 3(b) or 3(c),
any action by the Board or the Administrator to reduce the exercise price of any
outstanding Stock Option or to cancel any outstanding Stock Option and re-grant
such Stock Option at a lower exercise price, shall be subject to approval by the
Company's stockholders entitled to vote at a meeting of stockholders. Nothing in
this Section 8 shall limit the Board's authority to take any action permitted
pursuant to Section 3(c).

SECTION 9.  STATUS OF PLAN

     With respect to the portion of any Award that has not been exercised and
any payments in cash, Stock or other consideration not received by a
participant, a participant shall have no rights greater than those of a general
creditor of the Company unless the Administrator shall otherwise expressly
determine in connection with any Award or Awards. In its sole discretion, the
Administrator may authorize the creation of trusts or other arrangements to meet
the Company's obligations to deliver Stock or make payments with respect to
Awards hereunder, provided that the existence of such trusts or other
arrangements is consistent with the foregoing sentence.

SECTION 10.  CHANGE OF CONTROL PROVISIONS

     Upon the occurrence of a Change of Control as defined in this Section 10:

     (a)    Except as otherwise provided in the applicable Award agreement, each
outstanding Stock Option shall automatically become fully exercisable and any
Stock issued or issuable thereunder shall become free of any restrictions on
transfer.

     (b)    "Change of Control" shall mean the occurrence of any one of the
following events:

            (i)     any "PERSON," as such term is used in Sections 13(d) and
14(d) of the Act (other than the Company, any of its Subsidiaries, or any
trustee, fiduciary or other person or entity holding securities under any
employee benefit plan or trust of the Company or any of its Subsidiaries),
together with all "affiliates" and "associates" (as such terms are defined in
Rule 12b-2 under the Act) of such person, shall become the "beneficial owner"
(as such term is defined in Rule 13d-3 under the Act), directly or indirectly,
of securities of the Company representing 25 percent or more of the combined
voting power of the Company's then outstanding securities having the right to
vote in an election of the Company's Board of Directors ("Voting Securities")
(in such case other than as a result of an acquisition of securities directly
from the Company); or

                                        9
<Page>

            (ii)     the stockholders of the Company shall approve (A) any
consolidation or merger of the Company where the stockholders of the Company,
immediately prior to the consolidation or merger, would not, immediately after
the consolidation or merger, beneficially own (as such term is defined in Rule
13d-3 under the Act), directly or indirectly, shares representing in the
aggregate 50 percent or more of the voting shares of the corporation issuing
cash or securities in the consolidation or merger (or of its ultimate parent
corporation, if any), (B) any sale, lease, exchange or other transfer (in one
transaction or a series of transactions contemplated or arranged by any party as
a single plan) of all or substantially all of the assets of the Company or (C)
any plan or proposal for the liquidation or dissolution of the Company.

     Notwithstanding the foregoing, a "Change of Control" shall not be deemed to
have occurred for purposes of the foregoing clause (i) solely as the result of
an acquisition of securities by the Company which, by reducing the number of
shares of Voting Securities outstanding, increases the proportionate number of
shares of Voting Securities beneficially owned by any person to 25 percent or
more of the combined voting power of all then outstanding Voting Securities;
PROVIDED, HOWEVER, that if any person referred to in this sentence shall
thereafter become the beneficial owner of any additional shares of Voting
Securities (other than pursuant to a stock split, stock dividend, or similar
transaction or as a result of an acquisition of securities directly from the
Company), then a "CHANGE OF CONTROL" shall be deemed to have occurred for
purposes of the foregoing clause (i).

SECTION 11.  GENERAL PROVISIONS

     (a)    NO DISTRIBUTION; COMPLIANCE WITH LEGAL REQUIREMENTS. The
Administrator may require each person acquiring Stock pursuant to an Award to
represent to and agree with the Company in writing that such person is acquiring
the shares without a view to distribution thereof.

     No shares of Stock shall be issued pursuant to an Award until all
applicable securities law and other legal and stock exchange or similar
requirements have been satisfied. The Administrator may require the placing of
such stop-orders and restrictive legends on certificates for Stock and Awards as
it deems appropriate.

     (b)    DELIVERY OF STOCK CERTIFICATES. Stock certificates to participants
under this Plan shall be deemed delivered for all purposes when the Company or a
stock transfer agent of the Company shall have mailed such certificates in the
United States mail, addressed to the participant, at the participant's last
known address on file with the Company.

     (c)    OTHER COMPENSATION ARRANGEMENTS; NO EMPLOYMENT RIGHTS. Nothing
contained in this Plan shall prevent the Board from adopting other or additional
compensation arrangements, including trusts, and such arrangements may be either
generally applicable or applicable only in specific cases. The adoption of this
Plan and the grant of Awards do not confer upon any employee any right to
continued employment with the Company or any Subsidiary.

     (d)    TRADING POLICY RESTRICTIONS. Option exercises and other Awards under
the Plan shall be subject to such Company's insider-trading-policy-related
restrictions, terms and

conditions as may be established by the Administrator, or in accordance with
policies set by the Administrator, from time to time.

     (e)    LOANS. The Board may, in its sole discretion, authorize the grant of
loans to selected key employees to be used solely for the purchase of shares of
Stock or payment of taxes in connection with Awards under the Plan. The terms of
such loans shall be determined at the sole discretion of the Board. Such loans
shall be secured by the shares of Stock, and may be made with or without
recourse against the employee.
