         WHEREAS, as of the date hereof Comerica Bank ("Comerica") is joining

         NOW, THEREFORE, the parties hereto, in consideration of their mutual
covenants and agreements hereinafter set forth and intending to be legally bound
hereby, covenant and agree as follows:

1. Definitions.

         Defined terms used herein unless otherwise defined herein shall have
the meanings ascribed to them in the Credit Agreement as amended by this
Amendment.

2. Amendment of Credit Agreement.

         (a)      Section 1.1 [Certain Definitions] is hereby amended by
                  amending and restating the definition of "Required Banks" as
                  follows:

                  "Required Banks shall mean

                           (i) if there are no Loans, Reimbursement Obligations
                  or Letter of Credit Borrowings outstanding; (x) Banks whose
                  Commitments aggregate at least 66 and 2/3% of the Commitments
                  of all of the Banks and (y) if there are more than two (2)
                  Banks that have Commitments hereunder and if a single Bank's
                  Commitments aggregate at least 66 and 2/3% of the Commitments
                  of all of the Banks, then an additional Bank;

                           (ii) if there are Loans, Reimbursement Obligations,
                  or Letter of Credit Borrowings outstanding; (x) Banks whose
                  Loans, Reimbursement Obligations and Letter of Credit

                  the total principal amount of all of the Loans,

<PAGE>   2

                  Reimbursement Obligations and Letter of Credit Borrowings then
                  outstanding and (y) and if more than two (2) Banks have Loans,
                  Reimbursement Obligations and/or Letter of Credit Borrowings
                  then outstanding and if a single Bank's Loans, Reimbursement
                  Obligations and Letter of Credit Borrowings then outstanding
                  aggregates at least 66 and 2/3% of the total principal amount
                  of all of the Loans, Reimbursement Obligations and Letter of
                  Credit Borrowings then outstanding, then an additional Bank.
                  Reimbursement Obligations and Letter of Credit Borrowings
                  shall be deemed, for purposes of this definition, to be in
                  favor of the Agent and not a participating Bank if such Bank
                  has not made its Participation Advance in respect thereof and
                  shall be deemed to be in favor of such Bank to the extent of
                  its Participation Advance if it has made its Participation
                  Advance in respect thereof."

         (b)      Section 2.10.1 of the Credit Agreement is hereby amended and
                  restated in its entirety as follows:

                  "2.10.1 Requests; Approval by All Banks.

                   No sooner than ninety (90) but not less than sixty
(60) days prior to the Expiration Date, the Borrower may request a 364-day
extension of the Expiration Date by written notice to the Agent and the Banks,
and the Banks agree to respond to the Borrower's request for an extension by the
later of forty-five (45) days following receipt of the request or September 30,
2001; provided, however, that the failure of any Bank to respond within such
time period shall not in any manner constitute an agreement by such Bank to
extend the Expiration Date. If all Banks elect to extend, the extension shall be
effective as of the Expiration Date and the Expiration Date shall be extended
for a period of 364 days. If one or more Banks decline to extend or do not
respond to Borrower's request, the provisions of Section 2.10.2 shall apply."

         (c)      Section 6.1.2 of the Credit Agreement is hereby amended and
                  restated in its entirety as follows:

                  "6.1.2 Capitalization and Ownership.

                  The authorized capital stock of the Borrower, as of the
Closing Date, consists of (a) 500,000,000 shares of Common Stock, par value $.01
per share, of which 38,107,009 shares (referred to herein as the "Common
Shares") are issued and outstanding; and (b) 5,000,000 shares of Preferred
Stock, par value $.01 per share, none of which are issued and outstanding. All

                                FREEMARKETS, INC.
                SECOND AMENDED AND RESTATED STOCK INCENTIVE PLAN

1.       PURPOSE OF THE PLAN.

         The purpose of the FreeMarkets, Inc. Second Amended and Restated Stock
Incentive Plan (originally named the FreeMarkets OnLine, Inc. 1998 Stock Option
Plan) (the "Plan") is to promote the interests of FreeMarkets, Inc. (the
"Company"), its subsidiaries and its stockholders by (i) attracting and
retaining employees, officers, directors, consultants and advisors of
outstanding ability, (ii) motivating such persons, by means of
performance-related incentives, to achieve long-range performance goals, and
(iii) enabling such persons to participate in the long-term growth and financial
success of the Company and its subsidiaries. The original effective date of the
Plan was March 2, 1998 ("Effective Date"); the Plan was subsequently amended and
restated as of June 30, 1999 ("Restated Effective Date") and was thereafter
amended to reflect a change in the Company"s name, and to clarify certain
aspects of Plan operation, effective as of the Restated Effective Date. The Plan
was amended, restated and renamed the "Second Amended and Restated Stock
Incentive Plan" as of January 2, 2001 to eliminate certain provisions of Section
12 of the Amended and Restated Stock Incentive Plan and to clarify certain
aspects of Section 12 thereof. Except as otherwise specifically provided herein,
the Plan as amended and restated applies generally to Options (as defined in
Section 3) granted prior to, as well as Options and Restricted Stock (as defined
in Section 3) granted on and after, the Restated Effective Date.

2.       ADMINISTRATION.

         (a) Subject to the following paragraphs, the Plan shall be administered
by the Company's Board of Directors (the "Board") or by a Compensation Committee
of the Board (the "Compensation Committee"). If the Board delegates to the
Compensation Committee the authority to administer the Plan, the Compensation
Committee shall be empowered to take all actions reserved to the Board under the
Plan. The Board is authorized to interpret the Plan, to prescribe, amend and
rescind rules and regulations to further the purposes of the Plan, and to make
all other determinations necessary for the administration of the Plan. All such
actions by the Board shall be conclusive, final and binding on all recipients of
grants hereunder ("participants").

         (b) Following registration by the Company of its Common Stock, par
value $.01 per share ("Common Stock") under Section 12 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), any Compensation
Committee to which Plan administration is delegated shall consist solely of
Board members who qualify as (i) "Non-Employee Directors" as defined under Rule
16b-3 under the Exchange Act and (ii) "outside directors" as defined under
Section 162(m) or any successor provision of the Internal Revenue Code of 1986,
as amended (the "Code") and applicable Treasury regulations thereunder, if and
to the extent such qualification is necessary so that grants made under the Plan
or the exercise of rights thereunder will qualify for any tax or other material
benefit to participants or the Company and its subsidiaries under applicable
law.

         (c) Notwithstanding the foregoing, the Board may, subject to any
limitations or restrictions the Board may impose from time to time, delegate to
the Chief Executive Officer the authority to administer the Plan, including the
authority to grant Options (as hereinafter defined) to employees, consultants or
advisors of the Company and its subsidiaries who are not subject, by reason of

<PAGE>   2

their position with the Company or its subsidiaries, to the requirements of
Section 16 of the Exchange Act and who are not expected to be subject to the
limitations of Code Section 162(m).

3.       GRANTS.

         Grants under the Plan may be in the form of options which qualify as
"incentive stock options" within the meaning of Code Section 422 or any
successor provision ("Incentive Stock Options"), options which do not so qualify
("Nonqualified Options" and, collectively with Incentive Stock Options,
"Options"), and stock which is subject to certain forfeiture risks and
restrictions on transferability ("Restricted Stock"). Incentive Stock Options
may be granted only to employees of the Company or its subsidiaries. Each grant
of an Option shall be designated in the applicable "Grant Instrument" (as
defined in Section 5) as an Incentive Stock Option or a Nonqualified Option, as
appropriate. If, notwithstanding its designation as an Incentive Stock Option,
all or a portion of any Option grant does not qualify under the Code as an
Incentive Stock Option, the portion which does not so qualify shall be treated
for all purposes hereunder as a Nonqualified Option.

4.       SHARES SUBJECT TO THE PLAN.

         Subject to adjustment as provided in Section 9, the maximum aggregate
number of shares of Common Stock that may be subject to grants made under the
Plan is 15,450,000 shares (plus any shares of Common Stock covered by any
unexercised portion of terminated stock options granted under the FreeMarkets
OnLine, Inc. 1996 Stock Incentive Plan (the "1996 Plan")), plus an automatic
annual increase on the first day of each fiscal year of the Company beginning on
or after January 1, 2001 and ending on or before December 31, 2008 equal to the
lesser of (i) 1,500,000 shares, (ii) 3% of the shares outstanding on the last
day of the immediately preceding fiscal year, or (iii) such lesser number of
shares as is determined by the Board. The Common Stock to be offered under the
Plan shall be authorized and unissued Common Stock or issued Common Stock which
shall have been reacquired by the Company and held in its treasury. The Common
Stock covered by any unexercised portion of terminated stock options granted
under the Plan or under the 1996 Plan, or by any grant of Restricted Stock which
is forfeited, may again be subject to new grants under the Plan. In the event
the purchase price of an Option is paid in whole or in part through the delivery
of Common Stock, only the net number of shares of Common Stock issuable in
connection with the exercise of the Option shall be counted against the number
of shares remaining available for grant under the Plan. At any time following
registration by the Company of its Common Stock under Section 12 of the Exchange
Act, no participant shall receive grants in respect of more than 2,000,000
shares of Common Stock in any calendar year (subject to adjustment as provided
in Section 9).

5.       PARTICIPANTS.

         The Board shall determine and designate from time to time those
employees, directors, consultants and advisors of the Company or its
subsidiaries who shall be granted Options or Restricted Stock under the Plan and
the number of shares of Common Stock to be covered by each such Option or
Restricted Stock grant; provided, that any such consultants or advisors who
receive grants under the Plan render bona fide services to the Company or its
subsidiaries that are not in connection with the offer or sale of securities in
a capital-raising transaction. In making its determinations, the Board shall
take into account the present and potential contributions of the respective
individuals to the success of the Company and its subsidiaries and such other
factors as the Board shall deem relevant in connection with accomplishing the
purposes of the Plan. Each grant shall be evidenced by a written Option or

                                       2
<PAGE>   3

Restricted Stock agreement or grant form ("Grant Instrument") as the Board shall
approve from time to time.

6.       FAIR MARKET VALUE.

         For all purposes under the Plan, the term "Fair Market Value" shall
mean, as of any applicable date, (i) if the principal securities market on which
the Common Stock is traded is a national securities exchange or The Nasdaq
National Market ("NNM"), the closing price of the Common Stock on such exchange
or NNM, as the case may be, or if no sale of the Common Stock shall have
occurred on such date, on the next preceding date on which there was a reported
sale; (ii) if the Common Stock is not traded on a national securities exchange
or NNM, the closing price on such date as reported by The Nasdaq SmallCap
Market, or if no sale of the Common Stock shall have occurred on such date, on
the next preceding date on which there was a reported sale; (iii) if the
principal securities market on which the Common Stock is traded is not a
national securities exchange, NNM or The Nasdaq SmallCap Market, the average of
the bid and asked prices reported by the National Quotation Bureau, Inc.; or
(iv) if the price of the Common Stock is not so reported, the Fair Market Value
of the Common Stock as determined in good faith by the Board.

7.       GRANTS OF OPTIONS.

         (a) Exercise Price of Options. Incentive Stock Options shall be granted
at an exercise price of not less than 100% of the Fair Market Value on the date
of grant; provided, however, that Incentive Stock Options granted to a
participant who at the time of such grant owns (within the meaning of Code
Section 424(d)) more than 10% of the voting power of all classes of stock of the
Company (a "10% Holder") shall be granted at an exercise price of not less than
110% of the Fair Market Value on the date of grant. Nonqualified Options shall
be granted at an exercise price as determined in each case by the Board.

         (b) Term and Termination of Options.

                  (1) The Board shall determine the term within which each
Option may be exercised, in whole or in part, provided that (i) such term shall
not exceed 10 years from the date of grant, (ii) the term of an Incentive Stock
Option granted to a 10% Holder shall not exceed 5 years from the date of grant,
and (iii) the aggregate Fair Market Value (determined on the date of grant) of
Common Stock with respect to which Incentive Stock Options granted to a
participant under the Plan or any other plan of the Company and its subsidiaries
become exercisable for the first time in any single calendar year shall not
exceed $100,000.

                  (2) Unless otherwise determined by the Board, all rights to
exercise Options shall terminate on the first to occur of (i) the scheduled
expiration date as set forth in the applicable Grant Instrument, (ii) 60 days
following the date of termination of employment for any reason other than the
participant"s death or permanent disability (as defined in Code Section
22(e)(3)), (iii) 1 year following the date of termination of employment or
provision of services by reason of the participant's death or permanent
disability (as defined in Code Section 22(e)(3)), or (iv) as may be otherwise
provided in the event of a Change of Control as defined in Section 11; provided,
however, that in the event that a participant ceases to be employed by or to
provide services to the Company and its subsidiaries due to a termination for
"cause" (as defined in Section 7(b)(3)), all rights to exercise Options held by

                                       3
<PAGE>   4

such participant shall terminate immediately as of the date such participant
ceases to be employed by or to provide services to the Company or its
subsidiaries.

                  (3) As used in this Plan, the term "cause" shall mean a
finding by the Board that the participant has engaged in conduct that is
fraudulent, disloyal, criminal or injurious to the Company or its subsidiaries,
including, without limitation, embezzlement, theft, commission of a felony or
dishonesty in the course of his or her employment or service, or the disclosure
of trade secrets or confidential information of the Company or its subsidiaries
to persons not entitled to receive such information.

         (c) Payment for Shares. Full payment for shares purchased upon exercise
of Options granted under the Plan shall be made at the time the Options are
exercised in whole or in part. Payment of the purchase price shall be made in
cash or in such other form as the Board may approve, including, without
limitation, (i) by the participant's delivery to the Company of a promissory
note containing such terms as the Board may determine, (ii) by the participant's
delivery to the Company of shares of Common Stock that have been held by the
participant for at least six months prior to exercise of the Options, valued at
the Fair Market Value of such shares on the date of exercise, or (iii) if the
Common Stock is publicly traded, pursuant to a cashless exercise arrangement
with a broker on such terms as the Board may determine; provided, however, that
if payment is made pursuant to clause (i), the then par value of the purchased
shares shall be paid in cash. No shares of Common Stock shall be issued to the
participant until such payment has been made, and a participant shall have none
of the rights of a stockholder with respect to Options held by such participant.

         (d) Other Terms and Conditions. The Board shall have the discretion to
determine terms and conditions, consistent with the Plan, that will be
applicable to Options, including, without limitation, performance-based criteria
for acceleration of the date on which certain Options shall become exercisable.
Options granted to the same or different participants, or at the same or
different times, need not contain similar provisions.

         (e) Substitution of Options. Options may be granted under the Plan from
time to time in substitution for stock options of other entities ("Acquired
Companies") in connection with the merger or consolidation of the Acquired
Company with the Company or its subsidiaries, the acquisition by the Company or
by its subsidiaries of all or a portion of the assets of the Acquired Company,
or the acquisition of stock of the Acquired Company such that the Acquired
Company becomes a subsidiary of the Company.

8.       GRANTS OF RESTRICTED STOCK.

         The Board may issue or transfer shares of Common Stock to employees,
directors, consultants or advisors under a grant of Restricted Stock, upon such
terms as the Board deems applicable, including the provisions set forth below:

         (a) General Requirements. Shares of Common Stock issued or transferred
pursuant to Restricted Stock grants may be issued or transferred for
consideration or for no consideration, and subject to restrictions or no
restrictions, as determined by the Board. The Board may establish conditions
under which restrictions on shares of Restricted Stock shall lapse over a period
of time or according to such other criteria (including performance-based
criteria) as the Board deems appropriate.

                                       4
<PAGE>   5

The period of time during which the Restricted Stock will remain subject to
restrictions will be designated in the Grant Instrument as the "Restriction
Period."

         (b) Number of Shares. The Board shall determine the number of shares of
Common Stock to be issued or transferred pursuant to a Restricted Stock grant
and the restrictions applicable to such shares.

         (c) Requirement of Employment. If a participant who has received a
Restricted Stock grant ceases to be employed by the Company and its subsidiaries
during the Restriction Period, or if other specified conditions are not met, the
Restricted Stock grant shall terminate as to all shares covered by the grant as
to which the restrictions have not lapsed, and those shares of Common Stock
shall be canceled in exchange for the purchase price, if any, paid by the
participant for such shares. The Board may provide, however, for complete or
partial exceptions to this requirement as it deems appropriate.

         (d) Restrictions on Transfer and Legend on Stock Certificate. During
the Restriction Period, a participant may not sell, assign, transfer, donate,
pledge or otherwise dispose of the shares of Restricted Stock. Each certificate
for a share of Restricted Stock shall contain a legend giving appropriate notice
of the applicable restrictions. The participant shall be entitled to have the
legend removed from the stock certificate covering the shares of Restricted
Stock subject to restrictions when all restrictions on such shares lapse. The
Board may determine that the Company will not issue certificates for shares of
Restricted Stock until all restrictions on such shares lapse, or that the
Company will retain possession of certificates for shares of Restricted Stock
until all restrictions on such shares lapse.

         (e) Right to Vote and to Receive Dividends. During the Restriction
Period, the participant shall have the right to vote shares of Restricted Stock
and to receive any dividends or other distributions paid on such shares, subject
to any restrictions deemed appropriate by the Board.

         (f) Lapse of Restrictions. All restrictions imposed on Restricted Stock
shall lapse upon the expiration of the applicable Restriction Period and the
satisfaction of all conditions imposed by the Board. The Board may determine, as
to any or all Restricted Stock grants, that the restrictions shall lapse without
regard to any Restriction Period.

9.       ADJUSTMENTS TO REFLECT CAPITAL CHANGES.

         The number and kind of shares subject to outstanding grants, the
exercise price applicable to Options previously granted, and the number and kind
of shares available subsequently to be granted under the Plan shall be
appropriately adjusted to reflect any stock dividend, stock split, combination
or exchange of shares or other change in capitalization with a similar
substantive effect upon the Plan or grants under the Plan. The Board shall have
the power and sole discretion to determine the nature and amount of the
adjustment to be made in each case. The adjustment so made shall be final and
binding on all participants.

                                       5
<PAGE>   6

10.      RIGHT OF FIRST REFUSAL; RIGHT TO REPURCHASE.

         (a) At any time prior to registration by the Company of its Common
Stock under Section 12 of the Exchange Act, the Company shall have a right of
first refusal with respect to any proposed sale or other disposition by
participants (and their successors in interest by purchase, gift or other mode
of transfer) of any shares of Common Stock issued to them under the Plan which
are transferable. This right of first refusal shall be exercisable by the
Company in accordance with the terms and conditions established by the Board.

         (b) At any time prior to registration by the Company of its Common
Stock under Section 12 of the Exchange Act, in the event that a participant's
employment or service is terminated for cause (as defined in Section 7(b)(3)),
the Company shall have the right, exercisable within 90 days following such
termination, to repurchase any shares of Common Stock issued to such participant
under the Plan for the purchase price paid by such participant for such shares
of Common Stock.

11.      DEFINITION OF CHANGE OF CONTROL.

         For purposes of this Plan, a "Change of Control" shall mean the
occurrence of any of the following events:

         (a) the acquisition, other than from the Company, by any individual,
entity or group (within the meaning of Section 13(d)(3) or Section 14(d)(2) of
the Exchange Act), other than the Company or an employee benefit plan of the
Company, of beneficial ownership (within the meaning of Rule 13d-3 promulgated
under the Exchange Act) of more than 50% of the combined voting power of the
then outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Voting Securities"); or

         (b) the approval by the Company's stockholders of a reorganization,
merger, consolidation or recapitalization of the Company (a "Business
Combination"), other than a Business Combination in which more than 50% of the
combined voting power of the outstanding voting securities of the surviving or
resulting entity immediately following the Business Combination is held by the
persons who, immediately prior to the Business Combination, were the holders of
the Voting Securities; or

         (c) the approval by the Company's stockholders of a complete
liquidation or dissolution of the Company, or a sale of all or substantially all
of the Company's assets; or

         (d) individuals who, as of the Restated Effective Date, constitute the
Board (the "Incumbent Board") cease for any reason to constitute at least a
majority of the Board; provided, that any individual becoming a director
subsequent to such date whose election or nomination for election by the
Company's stockholders was approved by a vote of at least a majority of the
directors then comprising the Incumbent Board shall be considered as though such
individual were a member of the Incumbent Board.

12.      CONSEQUENCES OF A CHANGE OF CONTROL.

         (a) Unless otherwise determined by the Board, upon a Change of Control,
(i) each outstanding Option shall be assumed by the Acquiring Corporation (as
defined below) or parent thereof or replaced with a comparable option or right
to purchase shares of the capital stock, or equity equivalent instrument, of the
Acquiring Corporation or parent thereof, or other comparable rights (such
assumed and comparable options and rights, together, the "Replacement Options")
and (ii) each share of Restricted Stock shall be converted to a comparable
restricted grant of capital stock, or equity equivalent instrument, of the
Acquiring Corporation or parent thereof or other comparable restricted property
(such assumed and comparable restricted grants, together, the "Replacement
Restricted Stock"); provided, however, that if the Acquiring Corporation or
parent thereof does not grant Replacement Options and Replacement Restricted
Stock, then all outstanding Options which have been granted under the Plan and
which are not exercisable as of the effective date of the Change of Control
shall automatically accelerate and become exercisable immediately prior to the
effective date of the Change of Control, and all restrictions and conditions on
any Restricted Stock shall lapse upon the effective date of the Change of
Control. The term "Acquiring Corporation" means the surviving, continuing,
successor or purchasing corporation, as the case may be. Notwithstanding
anything in the Plan to the contrary, the Board shall have discretion, in the
applicable Grant Instrument or an amendment thereof, to provide for the
acceleration of Options and the elimination of restrictions on Restricted Stock
upon a Change of Control. The Board may determine in its discretion (but shall
not be obligated to do so) that in lieu of the issuance of Replacement Options,
all holders of outstanding Options which are exercisable immediately prior to a
Change of Control (including those that become exercisable under this Section
12(a)) will be required to surrender them in exchange for a payment, in cash or
Common Stock as determined by the Board, of an amount equal to the amount (if
any) by which the then Fair Market Value of Common Stock subject to unexercised
Options exceeds the exercise price of those Options, with such payment to take
place as of the date of the Change of Control or such other date as the Board
may prescribe.

         (b) Any Options that are not assumed or replaced by Replacement
Options, exercised or cashed out prior to or concurrent with a Change of Control
will terminate effective upon the Change of Control or at such other time as the
Board deems appropriate.

         (c) Notwithstanding anything in the Plan to the contrary, in the event
of a Change of Control, no action described in the Plan shall be taken
(including, without limitation, actions described in subsections (a), (b) and
(c) above) if such actions would make the Change of Control ineligible for
"pooling of interests" accounting treatment or would make the Change of Control
ineligible for desired tax treatment if, in the absence of such actions, the
Change of Control would qualify for such treatment and the Company intends to
use such treatment with respect to such Change of Control.

         (d) Section 12, as herein amended and restated, applies to Options and
Restricted Stock granted prior to, on and after the Restated Effective Date,
except as set forth in the next sentence. Section 12(b) of the Amended and
Restated Stock Incentive Plan, as in effect prior to January 2, 2001, applies to
Options and Restricted Stock granted prior to January 2, 2001.

                                       7
<PAGE>   8

13.      TRANSFERABILITY OF OPTIONS.

         Unless otherwise determined by the Board with respect to Nonqualified
Options, Options granted under the Plan shall not be transferable other than by
will or the laws of descent and distribution and are exercisable during a
participant's lifetime only by the participant.

14.      WITHHOLDING.

         The Company shall have the right to deduct any taxes required by law to
be withheld in respect of grants under the Plan from amounts paid to a
participant in cash as salary, bonus or other compensation. In the Board's
discretion, a participant may be permitted to elect to have withheld from the
shares otherwise issuable to the participant, or to tender to the Company, a
number of shares of Common Stock the aggregate Fair Market Value of which does
not exceed the applicable withholding rate for federal (including FICA), state
and local tax liabilities. Any such election must be in a form and manner
prescribed by the Board.

15.      CONSTRUCTION OF THE PLAN.

         The validity, construction, interpretation, administration and effect
of the Plan and of its rules and regulations, and rights relating to the Plan,
shall be determined solely by the Board. Any determination by the Board shall be
final and binding on all participants. The Plan shall be governed in accordance
with the laws of the State of Delaware, without regard to the conflict of law
provisions of such laws.

16.      NO RIGHT TO GRANT; NO RIGHT TO EMPLOYMENT.

         No person shall have any claim of right to be granted an Option or
Restricted Stock under the Plan. Neither the Plan nor any action taken hereunder
shall be construed as giving any employee any right to be retained in the employ
of the Company or any of its subsidiaries or as giving any consultant, advisor
or director of the Company or any of its subsidiaries any right to continue to
serve in such capacity.

17.      GRANTS NOT INCLUDABLE FOR BENEFIT PURPOSES.

         Income recognized by a participant pursuant to the provisions of the
Plan shall not be included in the determination of benefits under any employee
pension benefit plan (as such term is defined in Section 3(2) of the Employee
Retirement Income Security Act of 1974) or group insurance or other benefit
plans applicable to the participant which are maintained by the Company or any
of its subsidiaries, except as may be provided under the terms of such plans or
determined by resolution of the Board.

18.      NO STRICT CONSTRUCTION.

         No rule of strict construction shall be implied against the Company,
the Board or any other person in the interpretation of any of the terms of the
Plan, any grant made under the Plan or any rule or procedure established by the
Board.

                                       8
<PAGE>   9

19.      CAPTIONS.

         All Section headings used in the Plan are for convenience only, do not
constitute a part of the Plan, and shall not be deemed to limit, characterize or
affect in any way any provisions of the Plan, and all provisions of the Plan
shall be construed as if no captions had been used in the Plan.

20.      SEVERABILITY.

         Whenever possible, each provision in the Plan and every grant under the
Plan shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of the Plan or any grant under the Plan
shall be held to be prohibited by or invalid under applicable law, then such
provision shall be deemed amended to accomplish the objectives of the provision
as originally written to the fullest extent permitted by law, and all other
provisions of the Plan and every other grant under the Plan shall remain in full
force and effect.

21.      LEGENDS.

         All certificates for Common Stock delivered under the Plan shall be
subject to such transfer and other restrictions as the Board may deem advisable
under the rules, regulations and other requirements of the Securities and
Exchange Commission, any stock exchange or quotation system upon which the
Common Stock is then listed or quoted and any applicable federal or state
securities laws, and the Board may cause a legend or legends to be put on any
such certificates to make appropriate references to such restrictions.

22.      AMENDMENT.

         The Board may, by resolution, amend or revise the Plan, except that
such action shall not be effective without stockholder approval if such
stockholder approval is required to maintain the compliance of the Plan and/or
grants made to directors, executive officers or other persons with Rule 16b-3
promulgated under the Exchange Act or any successor rule. The Board may not
modify any Options previously granted under the Plan in a manner adverse to the
holders thereof without the consent of such holders, except in accordance with
the provisions of Sections 9, 12 or 23.

23.      MODIFICATION FOR GRANTS OUTSIDE THE U.S.

         The Board may, without amending the Plan, determine the terms and
conditions applicable to grants of Options or Restricted Stock to participants
who are foreign nationals or employed outside the United States in a manner
otherwise inconsistent with the Plan if the Board deems such terms and
conditions necessary in order to recognize differences in local law or
regulations, tax policies or customs.

24.      EFFECTIVE DATE; TERMINATION OF PLAN.

         The Plan was originally effective on March 2, 1998. The Restated
Effective Date is June 30, 1999. The Plan shall terminate on March 1, 2008,
unless it is earlier terminated by the Board. Termination of the Plan shall not
affect previous grants under the Plan.
