     The following information is furnished in connection with the solicitation
of proxies by the Board of Directors of the Corporation for the annual meeting
to be held on January 5, 2000. A copy of the annual report of the Corporation
for the fiscal year ended August 31, 1999 and a proxy for use at the meeting are
enclosed with this proxy statement. This proxy statement and the enclosed proxy
are initially being mailed to stockholders on or about November 22, 1999.

                              GENERAL INFORMATION

PROXY

     Stockholders are requested to provide their voting instructions on the
enclosed proxy by mail using the accompanying envelope, by the Internet, or by
telephone. Stockholders who hold their shares through a bank or broker can vote
by the Internet or by telephone if these options are offered by the bank or
broker. At any time before the proxy is voted, it may be revoked by written
notice to the Secretary of the Corporation. Proxies which are properly
delivered, and not revoked, will be voted in accordance with stockholders'
directions. Where no direction is specified, proxies will be voted for the
election of the nominees listed below as directors, for approval of the amended
and restated Long-Term Achievement Incentive Plan, and for ratification of the
appointment of Arthur Andersen LLP as independent auditors for the Corporation.

     Stockholders may deliver their proxy using one of the following methods:

     By the Internet.  Stockholders of record may give their voting instructions
by the Internet as described on the proxy card. Internet voting is also
available to stockholders who hold shares in the DirectService Plan, in the
Employee Stock Purchase Plan, or in a 401(k) plan sponsored by the Corporation.
The Internet voting procedure is designed to verify the voting authority of
stockholders. You will be able to vote your shares by the Internet and confirm
that your vote has been properly recorded. Please see your proxy card for
specific instructions.

     By Telephone.  Stockholders of record may give their voting instructions
using the toll-free number listed on the proxy card. Telephone voting is also
available to stockholders who hold shares in the DirectService Plan, in the
Employee Stock Purchase Plan, or in a 401(k) plan sponsored by the Corporation.
The telephone voting procedure is designed to verify the voting authority of
stockholders. The procedure allows you to vote your shares and to confirm that
your instructions have been properly recorded. Please see your proxy card for
specific instructions.

     By Mail.  Stockholders may sign, date, and mail their proxies in the
postage-paid envelope provided. If you sign, date, and mail your proxy card
without providing voting instructions on specific items, your proxy will be
voted as stated above.

STOCK OUTSTANDING AND VOTING RIGHTS

     As of November 8, 1999, the record date for the annual meeting, there were
40,690,942 shares of common stock outstanding and entitled to vote. The holders
of common stock, the only class of voting stock of the Corporation outstanding,
are entitled to one vote per share for the election of directors and on the
other matters presented.

VOTING PROCEDURE

     Votes cast by proxy or in person at the annual meeting will be tabulated by
the election inspector appointed for the meeting and will determine whether or
not a quorum is present. The election inspector will treat abstentions as shares
that are present and entitled to vote but as unvoted for purposes of determining
the approval of any matter submitted to the stockholders. If a broker indicates
on the proxy that it does not have discretionary authority as to certain shares
to vote on a particular matter, those shares will be considered as present but
not entitled to vote with respect to that matter.

SOLICITATION

     The cost of soliciting proxies is paid by the Corporation. Officers and
regular employees of the Corporation, at no additional compensation, may assist
in the solicitation of proxies. Solicitation will be by mail and perhaps by
telephone and personal contact.

                      ITEM NO. 1 -- ELECTION OF DIRECTORS

     At the annual meeting thirteen (13) directors of the Corporation will be
elected to hold office until the next annual meeting of stockholders and until
their successors are elected and qualified. To be elected, a nominee must
receive a plurality of the votes cast at the meeting. The persons named as
proxies in the accompanying proxy, or their substitutes, will vote for the
election of the nominees listed hereafter, except to the extent authority to
vote for any or all of the nominees is withheld. No nominee for election as a
director is proposed to be elected pursuant to any arrangement or understanding
between the nominee and any other person or persons. It is believed that all
such nominees are available for election. If any of the nominees are unable or
unwilling to serve, the persons named as proxies in the accompanying proxy, or
their substitutes, shall have full discretion and authority to vote or refrain
from voting for any substitute nominees in accordance with their judgment.

INFORMATION CONCERNING NOMINEES

     All of the nominees listed below, other than Leslie M. Baker, Jr., Ray M.

employee of the Corporation received an annual director fee of $40,000 and an
additional annual fee of $5,000 for serving as chairman of a committee, payable
quarterly in each case. Under the Nonemployee Director Deferred Stock Unit Plan,
each director was paid one-half of the annual fee, and may elect to receive
additional portions of the annual fee and the chairman fee, in deferred stock
units under the Plan. Nonemployee directors receive a one-time grant of 1,000
deferred stock units upon their election and an annual grant of 350 deferred
stock units. The value and return on deferred stock units is equivalent to the
value and return on NSI stock. The director's account is generally payable on or
after retirement; there is no other retirement plan for directors.

     Pursuant to the National Service Industries, Inc. 1992 Nonemployee
Directors' Stock Option Plan, stock options are granted annually on the day of
the Annual Meeting. Each nonemployee director received on January 6, 1999 a
grant of a nonqualified option for the purchase of 1,000 shares of common stock
at an exercise price of $37.375 per share, the fair market value on the grant
date. Each option grant is exercisable after one year and remains exercisable
for a period of ten years from the grant date.

     Directors may participate in the Corporation's Matching Gift Program. Under
this program, the Corporation will match charitable contributions up to a total

which business is conducted with these organizations are no less favorable than
those available from other organizations.

Corporation's directors and officers to file reports of ownership and changes in
ownership of the Corporation's stock with the Securities and Exchange
Commission, the New York Stock Exchange, and the Corporation. Based on a review
of the forms received by the Corporation during or with respect to the fiscal
year ended August 31, 1999, and written

                                        7

representations from certain reporting persons that no Form 5 reports were
required for those persons, the Corporation believes that all required Section
16(a) filings were made on a timely basis.

                             EXECUTIVE COMPENSATION

REPORT OF THE EXECUTIVE RESOURCE AND COMPENSATION COMMITTEE

     The Executive Resource and Compensation Committee of the Board of Directors
is composed entirely of nonemployee directors. The Committee is responsible for
approving the salary payable to the Chairman of the Board, President, and Chief
Executive Officer, subject to ratification by the full Board, for setting the
salary payable to each of the other executive officers of the Corporation, and
for administering the Management Compensation and Incentive Plan (the "Incentive
Plan"), subject to ratification of certain matters thereunder by the full Board.
The Committee had authority to grant awards under the Long-Term Incentive
Program (the "Long-Term Program") and now has that authority under the Long-Term
Achievement Incentive Plan (the "Long-Term Plan"). The Committee reviews and
makes recommendations to the Board with respect to any proposed awards to
executive officers under any other compensation plan, benefit plan, or
perquisite.

     Following below is a discussion of the compensation policies applicable to
the Corporation's executive officers, the executive officers' compensation
program for the last fiscal year, and the Chief Executive Officer's compensation
for the last fiscal year.

  Compensation Policies for Executive Officers

     The Corporation's compensation program is designed to attract, retain,
motivate, and reward qualified executives, with a linkage between the level of
an individual's compensation and the performance of the individual and the
Corporation. For the 1999 fiscal year, the principal compensation components
were base salary, bonus awards under the Incentive Plan, stock options granted
under the Long-Term Plan, and aspiration awards (described below) granted and
payable under the Long-Term Plan. Bonus awards, stock options, and aspiration
awards are generally granted on an annual basis. Salary adjustments are made
annually as merited or on promotion to a position of increased responsibilities.

     The Committee reviews the compensation of each executive officer utilizing
competitive compensation information prepared by an independent compensation
consultant and a performance review and recommendation by the Chief Executive
Officer for each other executive officer. The competitive compensation
information utilized by the Committee is for positions of comparable
responsibilities with comparably sized diversified companies, which are
representative of the companies with whom the Corporation competes for executive
talent. These companies are not necessarily the same as those included in the
peer index in the performance graph in this proxy statement.

     To the extent readily determinable and as one of the factors in its
consideration of compensation matters, the Committee considers the anticipated
tax treatment to the Corporation and to the executives of various payments and
benefits. Based on compensation arrangements currently in place, the Committee
does not reasonably anticipate that any executive officer's fiscal 1999 or 2000
compensation will be subject to the $1 million deductibility limitation of
Section 162(m) of the Internal Revenue Code. The Committee intends to retain the
deductibility of compensation pursuant to Section 162(m), but reserves the right
to provide non-deductible compensation if it determines that such action is in
the best interests of the Corporation and its stockholders.

 Executive Officers' 1999 Compensation

     The salary for fiscal 1999 of each executive officer (other than the Chief
Executive Officer, discussed below) was based on competitive compensation data
at the 75th percentile level and also considered the executive's performance,
experience, abilities, and expected future contribution.

     Bonuses for fiscal 1999 under the Incentive Plan were intended to provide
competitive total cash compensation at the 75th percentile level, subject to
achievement of the Corporation's target performance objectives. A bonus fund,
stated as a percentage of gross salary, was determined for each executive
officer based on the per-share earnings objective for the Corporation
established by the Committee and ratified by the Board of Directors at the
beginning of the fiscal year. The bonus fund increased or decreased in
relationship to earnings per share, with no bonus fund for earnings below a
threshold level. For fiscal 1999, the threshold level required the same level of
earnings per share as was achieved in fiscal 1998. Based on the Corporation's
                                        8
<PAGE>   11

earnings per share, adjusted downward for certain one-time amounts, the actual
bonus fund for each individual represented 180.0% of the target bonus fund.

     The compensation of executive officers for fiscal 1999 was further linked
with the Corporation's performance and to the increase in shareholder value
through long-term awards of stock options and aspiration awards granted under
the Long-Term Plan. Options provide compensation opportunities directly related
to, and contingent upon, the long-term performance of the Corporation and to the
increase in market value of its shares. Aspiration awards are long-term awards
designed to more clearly and quantifiably relate reward opportunities with
achievement of specific performance goals over a three-year cycle. The
performance measure is economic profit (adjusted after-tax profit minus a charge
for capital). The level of aspiration awards payable at the conclusion of the
cycle is expected to correlate with increases in stock price over time.
Long-term awards granted to executive officers in fiscal 1999 were based on
competitive long-term grants at approximately the 75th percentile level for
target level performance and are designed to provide higher compensation for
significantly higher performance.

     For the performance cycle ended August 31, 1999, executive officers earned
an aggregate aspiration award of 482.2% of target level, reflecting the high
level of economic profit achieved over the three-year cycle. Pursuant to an
amendment to the Long-Term Achievement Incentive Plan, and subject to approval
by stockholders of the amended and restated Plan, a portion of each officer's
earned award will be exchanged for stock options that are immediately
exercisable and have an exercise price per share equal to the fair market value
of a share on the date of the grant of the options. The remainder of the awards
were paid half in shares of stock and half in cash.

 Chief Executive Officer's 1999 Compensation

     For the 1999 fiscal year Mr. Balloun received base salary, an incentive
bonus, and stock options and an aspiration award under the Long-Term Plan. His
total compensation was based on competitive and merit factors. The Committee was
advised by an independent compensation consultant that Mr. Balloun's 1999 base
salary was competitive with the market third quartile, that his 1999 bonus
opportunity at target approximated the market median, and that his 1999
long-term incentive award value at target approximated the market median.

     The bonus paid to Mr. Balloun for fiscal 1999 was based on the
Corporation's earnings level, as specified by the Committee at the beginning of
the fiscal year and substantially as described above for executive officers. For
the performance cycle ended August 31, 1999, Mr. Balloun earned an aspiration
award of 482.2% of target level. Pursuant to an amendment to the Long-Term
Achievement Incentive Plan, and subject to approval by stockholders of the
amended and restated Plan, a portion of his earned award will be exchanged for
stock options that are immediately exercisable and have an exercise price per
share equal to the fair market value of a share on the date of the grant of the
options.

     Most of Mr. Balloun's compensation opportunity is provided through
performance-based bonus, aspiration awards, and stock options and is therefore
linked directly to performance on behalf of stockholders and to appreciation in
the market price of the Corporation's stock.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The directors serving on the Executive Resource and Compensation Committee
of the Board of Directors during the fiscal year ended August 31, 1999 were, for
the entire year, John L. Clendenin, Thomas C. Gallagher, James C. Kennedy, Betty
L. Siegel, and Barrie A. Wigmore, and for the portion of the year up to June 9,
1999, Charles W. McCall. None of these individuals are or have ever been
officers or employees of the Corporation. During the 1999 fiscal year, no
executive officer of the Corporation served as a director of any corporation
which any of these individuals served as an executive officer, and there were no
other

(1) Options have a ten-year term, subject to earlier termination upon certain
    events related to termination of employment, and vest in four equal annual
    installments beginning on the first anniversary of the grant date. The
    Executive Resource and Compensation Committee has discretion, subject to
    limitations in the Long-Term Incentive Program and the Long-Term Achievement
    Incentive Plan, to modify the terms of outstanding options and to reprice
    the options. Under the amended and restated Long-Term Achievement Incentive
    Plan being submitted for approval by stockholders, the Committee's authority
    to reprice options or grant options in substitution for surrendered options
    has been eliminated.
(2) The amounts shown were calculated using a Black-Scholes option pricing
    model. The estimated values assume a risk-free rate of return of 5.2%, a
    dividend yield of 2.63%, an option term of ten years, and stock price
    volatility having a standard deviation of .3620. The option values were not
    discounted to reflect the vesting period of the options or to reflect any
    exercise or lapse of the options prior to the end of the
    ten-year option period. The actual value, if any, that an executive may
    realize will depend upon the excess of the stock price over the exercise
    price on the date the option is exercised, so that there is no assurance the
    value realized by an executive will be at or near the value estimated by the
    Black-Scholes model.

(1) Aspiration awards will be payable based on the performance of the
    Corporation, as measured by cumulative economic profit (adjusted after-tax
    profit less a capital charge) over a three-year performance cycle ending
    August 31, 2001. Half of each payout will be in shares of stock and half
    will be in cash unless the Executive Resource and Compensation Committee
    determines otherwise.
(2) The numbers shown reflect the combined pro rata awards granted to Mr.
    Gilmore for certain performance cycles in progress as of June 1, 1999 (the
    date of his employment), based on the cumulative economic profit of the
    business units for which he is responsible. The respective threshold,
    target, and maximum payout amounts are as follows: for the performance cycle
    ending August 31, 2000, $22,500, $90,000, and $450,000; and for the
    performance cycle ending August 31, 2001, $40,500, $162,000, and $810,000.

EMPLOYMENT CONTRACTS, SEVERANCE ARRANGEMENTS, AND OTHER AGREEMENTS

     Pursuant to the Corporation's February 1, 1996 employment agreement with
Mr. Balloun and a related amendment to the Supplemental Retirement Plan for
Executives ("SERP"), Mr. Balloun will be credited with two years of service
under the SERP for each year of actual credited service and will be vested in
his SERP benefit after completing five years of employment.

     The employment agreement with Mr. Balloun provides for a lump sum severance
payment of $1.5 million in the event his employment is terminated after August
31, 1998. This provision does not apply in the event of voluntary termination,
termination upon death or disability, or termination for cause (as each such
term is defined in the agreement). In the event of termination in connection
with a Change in Control which would entitle Mr. Balloun to benefits under his
Severance Protection Agreement (described below), he would receive the greater
of the benefits under the Severance Protection Agreement or the severance
benefits set forth in his employment agreement.

     Pursuant to the Corporation's May 5, 1999 employment agreement with Mr.
Gilmore and a related amendment to the SERP, he will be credited with service
under the SERP for each year of actual service (from June 1, 1999 instead of
January 1, 2000) and vested in his SERP benefit after five years. The agreement
provides that in the event his employment is terminated by the Corporation on or
before June 1, 2000, (a) he will receive a severance payment, in semi-monthly
installments, equal to his then-current salary, from the date of termination
through June 1, 2002. In the event his employment is terminated by the
Corporation after June 1, 2000 but on or before June 1, 2009, he will receive a
severance payment, in 24 semi-monthly installments, equal to his then-current
salary. These provisions do not apply in the event of voluntary termination,
termination upon death or disability or for cause (as defined in the agreement),
or termination in connection with a Change in Control, discussed below.

     Pursuant to the Corporation's August 26, 1996 employment agreement with Mr.
Hattox and a related amendment to the SERP, he will be credited with service
under the SERP for each year of actual service (from September 18, 1996 instead
of January 1, 1998), vested in his SERP benefit after five years, and eligible
for early retirement at age 60.

     The Corporation has Severance Protection Agreements (the "Agreements") with
Messrs. Balloun, Gilmore, Hattox, Levy, and Searle. The Board intends for the
Agreements(which are similar) to provide the executives some measure of security
against the possibility of employment loss that may result following a change in
control in order that they may devote their energies to meeting the business
objectives and needs of the Corporation and its stockholders.

                                       13
<PAGE>   16

     The Agreement for Mr. Balloun is effective until his 65th birthday. The
Agreements for Messrs. Gilmore, Hattox, Levy, and Searle are effective for a
term of two years, which is automatically extended for one year at the end of
each year unless terminated by either party. However, the term of the Agreements
will not expire during a "Threatened Change in Control Period" (as defined in
the Agreements) or prior to the expiration of 24 months following a "Change in
Control" (as described below). If the employment of the officer is terminated
within 24 months following a Change in Control or in certain other instances in
connection with a Change in Control (1) by the Corporation other than for
"Cause" or "Disability" or (2) by the officer for "Good Reason" (as each term is
defined in the Agreements) or during the 60-day period commencing on the first
anniversary of the occurrence of a Change in Control, the officer will be
entitled to receive (a) a pro rata bonus for the year of termination, (b) a lump
sum cash payment equal to two times the sum of his base salary and bonus (in
each case at least equal to his base salary and bonus prior to a Change in
Control), subject to certain adjustments, (c) continuation of life insurance,
disability, medical, dental, and hospitalization benefits for a period of up to
24 months, and (d) a lump sum cash payment reflecting certain retirement
benefits he would have been entitled to receive had he remained employed by the
Corporation for an additional two years and a reduced requirement for early
retirement benefits. Additionally, all restrictions on any outstanding incentive
awards will lapse and become fully vested, all outstanding stock options will
become fully vested and immediately exercisable, and the Corporation will be
required to purchase for cash, on demand, at the then per-share fair market
value, any shares of unrestricted stock and shares purchased upon exercise of
options.

     The Agreements provide that the Corporation shall make an additional
"gross-up payment" to each officer to offset fully the effect of any excise tax
imposed under Section 4999 of the Internal Revenue Code of 1986, as amended (the
"Code"), on any payment made to him arising out of or in connection with his
employment. In addition, the Corporation will pay all legal fees and related
expenses incurred by the officer arising out of his employment or termination of
employment if, in general, the circumstances for which he has retained legal
counsel occurred on or after a Change in Control.

     Assuming a Change in Control had occurred on October 1, 1999 and their
employment had terminated on that date, the approximate cash payments that would
have been made under the Agreements (not including the gross-up payments) would
have been $4,810,003, $1,155,969, $1,582,316, $1,766,435, and $997,178 for
Messrs. Balloun, Gilmore, Hattox, Levy, and Searle, respectively. The amount of
the gross-up payment, if any, to be paid may be substantial and will depend upon
numerous factors, including the price per share of common stock of the
Corporation and the extent, if any, that payments or benefits made to the
officers constitute "excess parachute payments" within the meaning of Section
280G of the Code.

     A "Change in Control" includes (1) the acquisition (other than from the
Corporation) by any "person" (as that term is used for purposes of Sections
13(d) or 14(d) of the Exchange Act) other than a trustee of an employee benefit
plan maintained by the Corporation or certain related entities of beneficial
ownership of 20% or more of the combined voting power of the Corporation's then
outstanding voting securities, (2) a change in more than one-third of the
members of the Board who were either members as of September 21, 1989 or were
nominated or elected by a vote of two-thirds of those members or members so
approved, or (3) approval by stockholders of the Corporation of (i) a merger or
consolidation involving the Corporation if the stockholders of the Corporation
immediately before such merger or consolidation do not, as a result of such
merger or consolidation, own, directly or indirectly, more than seventy percent
(70%) of the combined voting power of the then outstanding voting securities of
the Corporation resulting from such merger or consolidation in substantially the
same proportion as their ownership of the combined voting power of the voting
securities of the Corporation outstanding immediately before such merger or
consolidation or (ii) a complete liquidation or dissolution of the Corporation
or an agreement for the sale or other disposition of all or substantially all of
the assets of the Corporation.

     Letter agreements issued to Messrs. Balloun, Gilmore, Hattox, Levy, and
Searle in conjunction with the Agreements provide that in the event of a Change
in Control, each such officer shall receive an annual cash bonus for that fiscal
year at least equal to the annual cash bonus paid to him in the prior fiscal
year if he remains in the employ of the Corporation for the full fiscal year.
The letter agreement with Mr. Balloun will expire on his 65th birthday. Each
other letter agreement has an initial term of 48 months and is subject to an
automatic one-year extension after each year unless terminated by the
Corporation, but in no event will the term expire following a Change in Control
until the Corporation's obligations as set forth therein have been satisfied.

PENSION AND SUPPLEMENTAL RETIREMENT BENEFITS

     The combined benefit under the Corporation's qualified defined benefit
retirement plan ("Pension Plan") and nonqualified supplemental retirement plan
for executives ("SERP"), as amended, is 45% of average base salary and bonus
(using the highest three consecutive years of remuneration out of the ten years
preceding the individual's retirement), less 50% of the individual's primary
social security benefit, and less the actuarial equivalent of the participant's
account in the 401(k) plan for corporate employees, assuming an annual
contribution of 4% of the individual's annual compensation over $15,000 (subject
to applicable limitations on eligible compensation), any applicable matching
contribution, and earnings on those amounts at 8% per annum.

     The following table shows the estimated aggregate annual benefits payable
to a covered participant at normal retirement age under the Pension Plan and
SERP, without the reduction under the SERP for the actuarial equivalent of
401(k) plan benefits (approximately $9,283 for Mr. Balloun, $28,559 for Mr.
Gilmore, $33,214 for Mr. Hattox, $11,747 for Mr. Levy, and $49,648 for Mr.
Searle):

     The remuneration specified in the table above consists of salary and annual
incentive bonus. Benefits shown above are based on payment of a single life
annuity with 10 years certain. Equivalent payment options are offered.

     The salary and bonus currently covered by the Pension Plan and the SERP for
each of the named executive officers substantially correspond to the amounts
disclosed in the Summary Compensation Table. The years of credited service for
each of the following named executive officers as of August 31, 1999 were: Mr.
Balloun, 3 years (6 years under the SERP); Mr. Gilmore, 0 years; Mr. Hattox, 2
years; Mr. Levy, 24 years; and Mr. Searle, 3 years.

               ITEM NO. 2 -- APPROVAL OF THE AMENDED AND RESTATED
                      LONG-TERM ACHIEVEMENT INCENTIVE PLAN

     In October 1999 , subject to approval of the Corporation's stockholders,
the Board of Directors adopted the amended and restated National Service
Industries, Inc. Long-Term Achievement Incentive Plan (the "Amended Plan") for
the benefit of officers and other key employees of the Corporation and its
subsidiaries (the "Participants"). Stockholder approval of the Amended Plan,
including the performance measures which may be utilized thereunder, is sought
(a) in order to qualify the Amended Plan under Section 162(m) of the Internal
Revenue Code of 1986 as amended ("Code") and to thereby allow the Corporation to
deduct for federal income tax purposes all compensation paid under the Amended
Plan to Named Executive Officers (generally, the executive officers who would be
listed for a fiscal year under the summary compensation table appearing on page
11 hereof) and (b) to satisfy the requirements of Section 422(b) of the Code so
that certain options issued under the Amended Plan may be "incentive stock
options."

     Approval of the Amended Plan requires the affirmative vote of a majority of
the shares of the Corporation's outstanding common stock present, in person or
by proxy, and entitled to vote at the Annual Meeting. In the event the Amended
Plan is not approved by the Corporation's stockholders, the Long-Term
Achievement Incentive Plan will continue without amendments incorporated in the
Amended Plan, and the Board of Directors will take such action with respect to
incentive awards as it considers to be in the best interests of the Corporation,
consistent with the compensation policies set forth in the Report of the
Executive Resource and Compensation Committee on page 8 of this proxy statement.

                                       15
<PAGE>   18

     The principal provisions of the Amended Plan are summarized below. This
summary is qualified in its entirety by reference to the full text of the
Amended Plan, which is attached hereto as Exhibit A.

PURPOSES OF THE AMENDED PLAN

     The general purposes of the Amended Plan are to provide additional
incentives to the Participants, whose substantial contributions are essential to
the continued growth and profitability of the Corporation's business, to
strengthen the commitment of the Participants to the Corporation and its
subsidiaries, to further motivate the Participants to perform their assigned
responsibilities diligently and skillfully, and to attract and retain competent
and dedicated individuals whose efforts will result in the long-term growth and
profitability of the Corporation and, over time, appreciation in the market
value of its stock.

NATURE OF THE AMENDMENTS

     The Amended Plan preserves the framework provided by the Long-Term
Achievement Incentive Plan approved by stockholders in January 1997. The
amendments incorporated in the Amended Plan modify the Plan in the following
ways: (a) shares authorized for issuance under the Plan are increased by
4,000,000 to 5,750,000; (b) grant size limitations are revised to the levels set
forth below in the descriptions of awards issuable under the Plan, are applied
with respect to each fiscal year of the Corporation (rather than with respect to
any twelve-month period), and are applied to all participants (not just Named
Executive Officers); (c) authority of the Committee administering the Plan to
reprice options or grant options in substitution for surrendered options is
eliminated; (d) an additional procedure (attestation) for exercising options is
authorized; (e) the number of shares to be issued in payment of an Aspiration
Achievement Incentive Award, and the payment of a Performance Unit in the form
of cash, is to be calculated in each case using the Fair Market Value determined
over the last ten trading days of the Performance Cycle (unless the Committee
provides otherwise in the Agreement setting forth the Award), rather than the
last day of the Performance Cycle; (f) the Committee is granted more flexibility
in setting the length of Performance Cycles for Aspiration Achievement Incentive
Awards, determining the effect of a Change in Control on payments of Aspiration
Achievement Incentive Awards and Performance Awards, and deferring payment of
Aspiration Achievement Incentive Awards; (g) the Committee is now required to
make adjustments for items or events that are "unusual" under generally accepted
accounting principles, as well as items or events that are "extraordinary"; (h)
restrictions that were originally in the Plan because of requirements of Section
16(b) of the Securities Exchange Act of 1934 (the "Exchange Act") and
regulations promulgated thereunder, or because of Section 162(m) of the Code,
but that are no longer necessary (because of amendments to or new
interpretations of those Sections or regulations) have been eliminated, but the
Amended Plan is still required to be interpreted and administered consistent
with Rule 16b-3 promulgated under the Exchange Act and is still drafted in a
manner such that grants and awards under the Amended Plan can be performance
based under Section 162(m) of the Internal Revenue Code.

DESCRIPTION OF THE PLAN

     The Amended Plan will be administered by a committee of at least three
directors (the "Committee"). The Committee currently designated is the Executive
Resource and Compensation Committee of the Board. The Amended Plan is a flexible
plan that will provide the Committee broad discretion to fashion the terms of
the following types of awards (described below): Stock Options (both Incentive
Stock Options and Nonqualified Stock Options), Aspiration Achievement Incentive
Awards, Restricted Stock, Performance Units, and Performance Shares
(individually and collectively, "Awards"). Not more than 30% of the maximum
number of Shares that may be issued or transferred pursuant to Awards under the
amended Plan may be in the form of Awards of Restricted Stock, Aspiration
Achievement Incentive Awards, Performance Shares, and Performance Units.

     The Committee will (a) select those Participants to whom Awards will be
granted and (b) determine the type, size and terms and conditions of Awards,
including the exercise price per Share for each Stock Option and the
restrictions or performance criteria relating to Aspiration Achievement
Incentive Awards, Restricted Stock, Performance Units and Performance Shares.
The Committee will administer, construe, and interpret the Amended Plan. Members
of the Committee will be ineligible to participate in the Amended Plan.

     5,750,000 shares of the Corporation's common stock ("Shares") may be issued
or transferred pursuant to the Amended Plan. In the event of any "Change in
Capitalization" (as defined in the Plan), the Committee may adjust the maximum
number and class of Shares with respect to which Awards may be granted, the

                                       16
<PAGE>   19

number and class of Shares which are subject to outstanding Awards (subject to
limitations imposed under Section 422 of the Code in the case of Incentive Stock
Options), and the purchase price therefor, if applicable.

     1,750,000 of the total 5,750,000 shares were approved by stockholders in
1997 under the Long-Term Plan and as of the record date are comprised as
follows: 1,140,331 option shares granted and outstanding; 181,658 shares issued
in payment of aspiration awards or upon exercise of options; and 428,011 shares
available for grant, subject to issuance in connection with outstanding
aspiration awards. The incremental 4,000,000 shares would be available for
future grants.

     The Amended Plan will terminate on September 18, 2006, the tenth
anniversary of the effective date of the Long-Term Achievement Incentive Plan.
The Board may terminate or amend the Amended Plan at any time (other than with
respect to the protections afforded to optionees and grantees upon a Change in
Control), unless such amendment or termination will adversely affect outstanding
Stock Options or Awards. However, to the extent legally required, no amendment
will be effective unless approved by stockholders.

AWARDS ISSUABLE UNDER THE PLAN

     Stock Options.  Both Incentive Stock Options and Nonqualified Stock Options
may be granted pursuant to the Amended Plan. The maximum number of Shares
subject to Stock Options which can be granted under the Amended Plan to any
Participant during a fiscal year of the Corporation is 500,000 Shares. All Stock
Options granted under the Amended Plan will have an exercise price per Share
equal to at least the fair market value of a Share on the date the Stock Option
is granted. The maximum term for all Stock Options granted under the Amended
Plan is ten years. Unless the Committee provides otherwise in the agreement
evidencing the Stock Options granted, Stock Options are nontransferable other
than by will or the laws of descent and distribution and during an optionee's
lifetime may be exercised only by the optionee or his guardian or legal
representative. Stock Options are exercisable at such time and in such
installments as the Committee may provide at the time the Stock Option is
granted. The Committee may accelerate the exercisability of any Stock Option at
any time, subject to any limitations required by Section 162(m) of the Code. The
purchase price for Shares acquired pursuant to the exercise of an Option must be
paid, as determined by the Committee, in cash, by check, or by transferring
Shares to the Corporation or attesting to ownership of shares upon such terms
and conditions as may be determined by the Committee. The terms and conditions
of the Stock Options relating to their treatment upon termination of the
optionee's employment will be determined by the Committee at the time the Stock
Options are granted.

     Upon a Change in Control, all outstanding Stock Options under the Amended
Plan on the date of a Change in Control will become immediately and fully
exercisable and the optionee may, during the 60-day period following the Change
in Control, surrender for cancellation any Stock Option (or portion thereof) for
a cash payment in respect of each Share covered by the Stock Option, or portion
thereof surrendered, equal to the excess of (1)(a) in the case of an Incentive
Stock Option, the per-Share Fair Market Value (as defined in the Plan) on the
date of surrender or (b) in the case of a Nonqualified Stock Option, the higher
of (x) the highest per-Share price at which Shares traded during the 90-day
period preceding the date of the Change in Control or (y) the price per Share
paid in any transaction (or series of transactions) constituting or resulting in
a Change in Control or (z) the per-Share Fair Market Value on the date preceding
the date of surrender, over (2) the purchase price of each Share.

     Aspiration Achievement Incentive Awards.  Aspiration Achievement Incentive
Awards ("Aspiration Awards") granted by the Committee will be payable based on
the level of achievement of the performance measure or measures specified by the
Committee, selected from the performance measures listed on Appendix A of the
amended Plan, over the performance period specified by the Committee (the
"Performance Cycle"). The performance measure may relate to the performance of
the Corporation or its subsidiaries or divisions, or any combination of the
foregoing, and the Performance Cycle will equal or exceed two years. Performance
measures and the length of the Performance Cycle will be determined by the
Committee at or near the beginning of the Performance Cycle when the Aspiration
Award is granted. Performance levels may be absolute or relative and may be
expressed in terms of a progression within a specified range. The agreement
setting forth the grant of an Aspiration Award may provide for such adjustments
to performance as the Committee deems appropriate and are not inconsistent with
Section 162(m) of the Code. Aspiration Awards may also include performance
levels that relate to individual achievements or goals. Except with respect to
Named Executive Officers, the Committee may establish performance measures in
addition to those specified in the Plan; moreover, the Committee may establish
additional performance measures with respect to Named Executive Officers without
stockholder approval if

                                       17
<PAGE>   20

laws change to give the Committee that discretion. No Participant may receive an
Aspiration Award in excess of $4 million with respect to a single Performance
Cycle.

     After the applicable Performance Cycle has ended, the Committee may adjust
the achieved performance levels to exclude the effects of unusual charges or
income items or other events, such as acquisitions or divestitures, which are
distortive of financial results for the Performance Cycle; provided that with
respect to Named Executive Officers, the Committee must, and can only, exclude
items with the effect of increasing the Aspiration Award payable if such items
constitute "extraordinary" or "unusual" events or items under generally accepted
accounting principles. The Committee will also adjust performance calculations
to exclude the unanticipated effect on financial results of changes in tax laws
or regulations. The Committee is allowed to decrease the Aspiration Award
otherwise payable if the performance during the Performance Cycle justifies such
adjustment, regardless of the extent to which the applicable performance measure
was achieved. The agreement evidencing the granting of an Aspiration Award may
provide the Committee with the right to revise performance levels and Aspiration
Awards payable if unforeseen events occur which have a substantial effect on
financial results and which in the Committee's judgment make the application of
the performance levels unfair; provided that for Named Executive Officers such
changes must be made in a manner not inconsistent with Section 162(m) of the
Code. Payment of an earned Aspiration Award will be made in cash, in Shares, or
in some combination of cash and Shares, as determined by the Committee. The
agreement evidencing the grant will also set forth the terms and conditions of
the Aspiration Award applicable in the event of termination of the Participant's
employment and in the event of a Change in Control.

     Restricted Stock.  The aggregate maximum number of Shares that may be
awarded under a Restricted Stock Award and an Award of Performance Shares and
Units to a Participant during any fiscal year of the Corporation is 100,000. The
terms of a Restricted Stock Award, including the restrictions placed on such
Shares and the time or times at which such restrictions will lapse, shall be
determined by the Committee at the time the Award is made. The Committee may
determine at the time an Award of Restricted Stock is granted that dividends
paid on Shares may be paid to the grantee or deferred. Deferred dividends
(together with any interest accrued thereon) will be paid upon the lapsing of
restrictions on Shares of Restricted Stock or forfeited upon the forfeiture of
Shares of Restricted Stock. The agreements evidencing Awards of Restricted Stock
shall set forth the terms and conditions of such Awards upon a grantee's
termination of employment. Unless the Committee provides otherwise in the
agreements, all restrictions on outstanding Shares of Restricted Stock will
lapse upon a Change in Control.

     Performance Units and Performance Shares.  Each Performance Unit will
represent one Share and payments in respect of vested Performance Units will be
made in cash, Shares, or Shares of Restricted Stock or any combination of the
foregoing, as determined by the Committee. Performance Shares are awarded in the
form of Shares of Restricted Stock. The vesting of Performance Units and
Performance Shares is based upon the level of achievement of the performance
measure or performance measures specified by the Committee, selected from the
performance measures listed on Appendix A of the amended Plan, over the
performance period specified by the Committee (the "Performance Cycle"). The
performance measure may relate to the performance of the Corporation or its
subsidiaries or divisions, or any combination of the foregoing. Performance
measures and the length of the Performance Cycle for Performance Units and
Performance Shares (which shall not be less than two years) will be determined
by the Committee at the time the Award is made. The Committee may make
adjustments to achieved performance levels and changes to performance measures
to the same extent described under Aspiration Achievement Incentive Awards
above. The agreements evidencing Awards of Performance Units and Performance
Shares will set forth the terms and conditions of such Awards, including those
applicable in the event of the grantee's termination of employment. The
aggregate maximum number of Performance Units, Performance Shares, and
Restricted Stock a Participant may be awarded for any fiscal year is 100,000.

     At the time an Award is made, the Committee will determine the total number
of Performance Shares subject to an Award and the time or times at which the
Performance Shares will be issued to the grantee. In addition, the Committee
will determine (a) the time or times at which the awarded but not issued
Performance Shares shall be issued to the grantee and (b) the time or times at
which awarded and issued Performance Shares shall become vested in or forfeited
by the grantee, in either case based upon the attainment of specified
performance objectives within the Performance Cycle. At the time the Award of
Performance Shares is made, the Committee may determine that dividends be paid
or deferred on the Performance Shares issued. Deferred dividends (together with
any interest accrued thereon) will be paid upon the lapsing of restrictions on
Performance Shares and forfeited upon the forfeiture of Performance Shares. Upon
a Change in Control, unless the Committee provides otherwise in the agreement
evidencing the Award,
                                       18
<PAGE>   21

(x) a percentage of Performance Units, as determined by the Committee at the
time an Award of Performance Units is made, will become vested and the grantee
will be entitled to receive a cash payment equal to the per Share adjusted Fair
Market Value multiplied by the number of Performance Units which become vested,
and (y) with respect to Performance Shares, all restrictions shall lapse on a
percentage of the Performance Shares, as determined by the Committee at the time
the Award of Performance Shares is made.

FEDERAL INCOME TAX CONSEQUENCES OF CERTAIN AWARDS

     An optionee will not recognize taxable income upon grant or exercise of an
Incentive Stock Option. However, upon the exercise of an Incentive Stock Option,
the excess of the fair market value of the Shares received over the exercise
price of the Shares subject to such Stock Option will be treated as an
adjustment to alternative minimum taxable income. Any dividends paid on Shares
will be taxable as ordinary income in the taxable year in which the dividend is
received. The Corporation and its subsidiaries will not be entitled to any
business expense deduction with respect to the grant or exercise of an Incentive
Stock Option, except as discussed below.

     In order for the exercise of an Incentive Stock Option to qualify for
favorable tax treatment, the optionee generally must be an employee of the
Corporation, parent, or a subsidiary (within the meaning of Section 422 of the
Code) from the date the Incentive Stock Option is granted through a date within
three months before the date of exercise. In the case of an optionee who is
disabled, the three-month period for exercise following termination of
employment may be extended to one year. In the case of an optionee's death, the
time for exercising Incentive Stock Options after termination of employment and
the holding period for stock received pursuant to the exercise of the Incentive
Stock Options are waived.

     If all of the requirements for Incentive Stock Option treatment are met and
the optionee has held the Shares for at least two years after the date of grant
and for at least one year after the date of exercise, upon disposition of the
Shares by the optionee, the difference, if any, between the sales price of the
Shares and the exercise price of the Stock Option will be treated as long-term
capital gain or loss. If the optionee does not hold the Shares in accordance
with the holding period rules set forth above, the optionee will recognize
ordinary income at the time of the disposition of the Shares, generally in an
amount equal to the excess of the fair market value of the Shares at the time
the Stock Option was exercised over the exercise price of the Stock Option. The
ordinary income recognized by an optionee upon the disposition of the Shares has
been determined by the IRS not to constitute wages for purposes of applicable
withholding tax requirements. The balance of the gain realized, if any, will be
long-term or short-term capital gain, depending upon whether or not the Shares
were sold more than one year after the Stock Option was exercised. If the
optionee sells the Shares prior to the satisfaction of the holding period rules
but at a price below the fair market value of the Shares at the time the Stock
Option was exercised, the amount of ordinary income will be limited to the
amount realized on the sale over the exercise price of the Stock Option. The
Corporation and its subsidiaries will be allowed a business expense deduction to
the extent the optionee recognizes ordinary income.

     An optionee to whom a Nonqualified Stock Option is granted will recognize
no income at the time of the grant of the Stock Option. Upon exercise of a
Nonqualified Stock Option, an optionee will recognize ordinary income in an
amount equal to the excess of the fair market value of the Shares on the date of
exercise over the exercise price of the Stock Option. If it complies with
applicable withholding requirements, the Corporation and its subsidiaries will
be entitled to a business expense deduction in the same amount and at the same
time as the optionee recognizes ordinary income. Upon a subsequent sale or
exchange of Shares acquired pursuant to the exercise of a Nonqualified Stock
Option, the optionee will have taxable gain or loss, measured by the difference
between the amount realized on the disposition and the tax basis of the shares
(generally, the amount paid for the Shares plus the amount treated as ordinary
income at the time the Stock Option was exercised).

     The Amended Plan provides that in satisfaction of the federal, state and
local income taxes and other amounts as may be required by law to be withheld
(the "Withholding Taxes") with respect to a Stock Option or Award, the optionee
or grantee may make a written election, which may be accepted or rejected in the
discretion of the Committee, to have withheld a portion of the Shares issuable
to him or her having an aggregate Fair Market Value equal to the Withholding
Taxes.

NEW PLAN BENEFITS

     The Committee may designate the employees eligible to participate in the
Plan each time it makes grants and awards under the Amended Plan. In the 1999
fiscal year, there were approximately 110 eligible employees under the Long-Term
Achievement Incentive Plan, including all five executive officers.

     Set forth in the table below are the numbers of options which have been
proposed to the Executive Resource and Compensation Committee for grant in
January 2000 for the persons and groups identified in the table.

     THE BOARD OF DIRECTORS BELIEVES IT IS IN THE BEST INTEREST OF THE
CORPORATION FOR THE STOCKHOLDERS TO APPROVE THE AMENDED AND RESTATED NATIONAL

     At the annual meeting, a proposal will be presented to ratify the

Corporation since 1964. Representatives of Arthur Andersen LLP are expected to
be present at the annual meeting, will have the opportunity to make a statement
if they desire, and are expected to be available to respond to questions of
stockholders. The total amount of fees charged by Arthur Andersen LLP for their
services during the fiscal year ended August 31, 1999, was $867,544,
substantially all of which was for services provided in connection with annual
audits, retirement plan audits, acquisition audits, and tax assistance.

The Corporation's By-laws, as amended effective immediately following the

meeting of stockholders any stockholder proposal which the Corporation is
permitted to exclude pursuant to the rules of the Securities and Exchange
Commission at the time such proposal is received.

     If a stockholder wishes to nominate a candidate for election as director at

Written notice of the stockholder's intent to make such nomination must be given

(A) the name and address of the stockholder and each person whom the stockholder
proposes to nominate as a director; (B) a representation that the stockholder is
a holder of record of stock of the Corporation entitled to vote at such meeting
and intends to appear in person or by proxy at the meeting to nominate the
person or persons specified in the notice; (C) a description of all arrangements

result in the long term growth and profitability of the Company and, over time,
appreciation in the market value of its stock. To accomplish these purposes, the
Plan provides that the Company may grant Incentive Stock Options, Nonqualified

and the terms and conditions of the Option shall be set forth in an Agreement.
The Committee shall have sole discretion in determining the number of Shares
underlying each Option to grant a Participant; provided, however, that in the
case of any Incentive Stock Option granted under the Plan, the aggregate Fair
Market Value (determined at the time such Option is granted) of the Shares to
which Incentive Stock Options are exercisable for the first time by the
Participant during any calendar year (under the Plan and all other incentive
stock option plans of the Company and any Subsidiary) shall not exceed $100,000.
The maximum number of Shares subject to Options which can be granted under the
Plan during a fiscal year of the Company to any Participant, including a Named
Executive Officer, is 500,000 Shares. Each Option and Agreement shall be subject
to the following conditions:

          (a) PURCHASE PRICE.  The purchase price or the manner in which the
     purchase price is to be determined for Shares under each Option shall be
     set forth in the Agreement, provided, that the purchase price per Share
     under each Option shall not be less than 100% of the Fair Market Value of a
     Share on the date the Option is granted (110% in the case of an Incentive
     Stock Option granted to a Ten-Percent Stockholder).

          (b) DURATION.  Options granted hereunder shall be for such term as the
     Committee shall determine, provided that no Option shall be exercisable
     after the expiration of ten (10) years from the date it is granted (five
     (5) years in the case of an Incentive Stock Option granted to a Ten-Percent
     Stockholder). The Committee may, subsequent to the granting of any Option,
     extend the term thereof, but in no event shall the term as so extended
     exceed the maximum term provided for in the preceding sentence.

          (c) NON-TRANSFERABILITY.  Unless the Committee otherwise provides in
     the Agreement, no Option granted hereunder shall be transferable by the
     Optionee, otherwise than by will or the laws of descent and distribution,
     and an Option may be exercised during the lifetime of such Optionee only by
     the Optionee or his guardian or legal representative. The terms of such
     Option shall be final, binding and conclusive upon the beneficiaries,
     executors, administrators, heirs and successors of the Optionee.

          (d) VESTING.  Subject to Section 6(h) hereof, each Option shall be
     exercisable in such installments (which need not be equal or the same for
     each Optionee) and at such times as may be designated by the Committee and
     set forth in the Agreement. To the extent not exercised, installments shall
     accumulate and be exercisable, in whole or in part, at any time after
     becoming exercisable, but not later than the date the Option expires. The
     Committee may accelerate the exercisability of any Option or portion
     thereof at any time.

          (e) METHOD OF EXERCISE.  The exercise of an Option shall be made only
     by a written notice delivered in person or by mail to the Secretary of the
     Company at the Company's principal executive office, specifying the number
     of Shares to be purchased and accompanied by payment therefor and otherwise
     in accordance with the Agreement pursuant to which the Option was granted.
     The purchase price for any Shares purchased pursuant to the exercise of an
     Option shall be paid in full upon such exercise, as determined by the
     Committee in its discretion, in cash, by check, or by transferring Shares
     to the Company or by attesting to the ownership of Shares upon such terms
     and conditions as determined by the Committee. The written notice pursuant
     to this Section 6(e) may also provide instructions from the Optionee to the
     Company that upon receipt of the purchase price in cash from the Optionee's
     broker or dealer, designated as such on the written notice, in payment for
     any Shares purchased pursuant to the exercise of an Option, the Company
     shall issue such Shares directly to the designated broker or dealer. Any
     Shares the Optionee transfers to the Company or attests to owning as
     payment of the purchase price under an Option shall be valued at their Fair
     Market Value on the day preceding the date of exercise of such Option. If
     requested by the Committee, the Optionee shall deliver the Agreement
     evidencing the Option to the Secretary of the Company who shall endorse
     thereon a notation of such exercise and return such Agreement to the
     Optionee. No fractional Shares shall be issued upon exercise of an Option
     and the number of Shares that may be purchased upon exercise shall be
     rounded to the nearest number of whole Shares.

          (f) RIGHTS OF OPTIONEES.  No Optionee shall be deemed for any purpose
     to be the owner of any Shares subject to any Option unless and until (i)
     the Option shall have been exercised pursuant to the terms thereof, (ii)
     the Company shall have issued and delivered the Shares to the Optionee and
     (iii) the Optionee's name shall have been entered as a stockholder of
     record on the books of the

                                       A-5
<PAGE>   29

     Company. Thereupon, the Optionee shall have full voting, dividend and other
     ownership rights with respect to such Shares.

          (g) TERMINATION OF EMPLOYMENT.  The Agreement shall set forth the
     terms and conditions of the Option upon the termination of the Optionee's
     employment with the Company, a Subsidiary or a Division (including an
     Optionee's ceasing to be employed by a Subsidiary or Division as a result
     of the sale of such Subsidiary or Division or an interest in such
     Subsidiary or Division), as the Committee may, in its discretion, determine
     at the time the Option is granted or thereafter, provided, however no
     Option shall be exercisable beyond its maximum term as described in Section
     6(b) hereof.

          (h) EFFECT OF CHANGE IN CONTROL.  Notwithstanding anything contained
     in the Plan or an Agreement to the contrary, in the event of a Change in
     Control, (i) all Options outstanding on the date of such Change in Control
     shall become immediately and fully exercisable and (ii) an Optionee will be
     permitted to surrender for cancellation within sixty (60) days after such
     Change in Control, any Option or portion of an Option to the extent not yet
     exercised and the Optionee will be entitled to receive a cash payment in
     the amount equal to the excess, if any, of (x) (A) in the case of a
     Nonqualified Stock Option, the greater of (1) the Fair Market Value, on the
     date preceding the date of surrender, of the Shares subject to the Option
     or portion thereof surrendered or (2) the Adjusted Fair Market Value of the
     Shares subject to the option or portion thereof surrendered or (B) in the
     case of an Incentive Stock Option, the Fair Market Value, at the time of
     surrender, of the Shares subject to the Option or portion thereof
     surrendered, over (y) the aggregate purchase price for such Shares under
     the Option.

          (i) MODIFICATION.  Subject to the terms of the Plan, the Committee
     may, in its discretion, modify outstanding Options. Notwithstanding the
     foregoing, (a) no modification of an Option shall adversely alter or impair
     any rights or obligations under the Agreement without the Optionee's
     consent, and (b) the Committee shall not have authority to modify
     outstanding options or accept the surrender of outstanding options and
     grant new options in substitution for them or to change the exercise price
     of any outstanding Option.

     7. ASPIRATION ACHIEVEMENT INCENTIVE AWARDS.

          (a) GRANT OF ASPIRATION AWARDS.  Subject to the terms of the Plan, the
     Committee may grant Aspiration Awards to Eligible Employees. The Committee
     shall have the discretion to determine the amount of each Aspiration Award
     and the other terms and conditions relating to the grant of such awards.

          (b) TERMS OF ASPIRATION AWARDS.  The following rules shall apply to
     the Aspiration Awards:

             (i) Prior to or at the beginning of the Performance Cycle (or
        within such time period as is permitted by Code Section 162(m) and the
        regulations thereunder), the Committee shall determine, based upon the
        Participant's salary and level of responsibility, the Aspiration Award
        applicable to the Participant. The Award will contain performance levels
        related to the Performance Measure(s) that will determine the actual
        award the Participant will receive at the end of the Performance Cycle.
        The Committee will select one or more of the Performance Measures listed
        on Appendix A (which objectives may be different for different
        Participants or Performance Cycles) for purposes of the Aspiration
        Awards under the Plan. Performance Measures may be in respect of the
        performance of the Company and its Subsidiaries on a consolidated basis,
        or a Subsidiary or a Division, or some combination of the foregoing.
        Performance levels with respect to a Performance Measure may be absolute
        or relative and may be expressed in terms of a progression within a
        specified range. The agreement for an Aspiration Award may provide for
        such adjustments to the financial performance of the Company (or a
        Division or Subsidiary) for the Performance Cycle as the Committee deems
        appropriate and are not inconsistent with Code Section 162(m).
        Aspiration Awards may also include performance levels that relate to
        individual achievements or goals. Except with respect to Named Executive
        Officers, the Committee may establish additional Performance Measures
        for purposes of Aspiration Awards under the Plan. Further, in the event
        that applicable tax and/or securities laws (including, but not limited
        to, Code Section 162(m) and Section 16 of the Exchange Act) change to
        permit Committee discretion to alter the governing Performance Measures
        for Named Executive Officers without obtaining stockholder approval of
        such changes, the Committee shall have sole discretion to make such
        changes without obtaining stockholder approval.

                                       A-6
<PAGE>   30

             (ii) No Participant may receive an Aspiration Award in excess of $4
        million with respect to a single Performance Cycle.

          (c) EARNING OF ASPIRATION AWARDS.  After the applicable Performance
     Cycle has ended, the Committee shall certify the extent to which the
     performance levels for the Performance Measure(s) have been achieved. In
     addition to any adjustments provided for by the Agreement, the Committee
     may, in determining whether the performance levels have been met, adjust
     the financial results for a Performance Cycle to exclude the effect of
     unusual charges or income items, or other events (such as acquisitions or
     divestitures and equity and other restructurings), which are distortive of
     financial results for the Performance Cycle; provided, that, with respect
     to Named Executive Officers, in determining financial results, items whose
     exclusion from consideration will increase the Award shall only have their
     effects excluded if they constitute "extraordinary" or "unusual" events or
     items under generally accepted accounting principles and all such events
     and items shall be excluded. The Committee shall also adjust the
     performance calculations to exclude the unanticipated effect on financial
     results of changes in the Code, or other tax laws, and the regulations
     thereunder. The Committee may decrease the amount of an Award otherwise
     payable if, in the Committee's view, the financial performance during the
     Performance Cycle justifies such adjustment, regardless of the extent to
     which the Performance Measure was achieved.

          The Agreement may provide the Committee with the right, during a
     Performance Cycle or after it has ended, to revise the performance levels
     for the Performance Measure and the Award amounts, if unforeseen events
     (including, without limitation, a Change in Capitalization, an equity
     restructuring, an acquisition or a divestiture) occur which have a
     substantial effect on the financial results and which in the judgment of
     the Committee make the application of the performance levels unfair unless
     a revision is made. For Named Executive Officers, such changes shall be
     made in a manner that is not inconsistent with Code Section 162(m).

          (d) FORM AND TIMING OF PAYMENT OF ASPIRATION AWARDS.  The Agreement
     shall set forth the manner in which payment of earned Aspiration Awards
     will be made. Payment will be made in cash or in Shares, or in a
     combination of cash and Shares, as determined by the Committee in the
     Agreement. Payment will be made as soon as practical after the end of the
     Performance Cycle to which the Award relates. Unless the Committee provides
     otherwise in the Agreement, for purposes of the portion of the Award paid
     in Shares, the Shares shall be valued as the average of their Fair Market
     Value for the last 10 trading days of the Performance Cycle.
     Notwithstanding the foregoing, the Committee may permit a Participant to
     elect to surrender all or a portion of an earned Aspiration Award in
     exchange for Options upon such terms and conditions as may be established
     by the Committee. The Committee may, in its sole discretion, defer payment
     of an Award or a portion thereof and provide for payment at a later date,
     if the Committee believes such payment if not deferred would violate
     Section 162(m).

          (e) TERMINATION OF EMPLOYMENT.  The Agreement shall set forth the
     terms and conditions of the Aspiration Award upon the termination of the
     Participant's employment with the Company, Subsidiary or a Division
     (including a Participant's ceasing to be employed by a Subsidiary or
     Division as a result of the sale of such Subsidiary or Division or an
     interest in such Subsidiary or Division), as the Committee may, in its
     discretion, determine at the time the Aspiration Award is granted or
     thereafter.

          (f) NONTRANSFERABILITY.  Unless the Agreement provides otherwise,
     Aspiration Awards may not be sold, transferred, pledged, assigned or
     otherwise alienated or hypothecated, other than, if amounts are payable
     after the Participant's death, by will or by the laws of descent and
     distribution.

          (g) EFFECT OF CHANGE IN CONTROL.  In the event of a Change in Control,
     the Participant shall earn and become entitled to payment of such portion
     of the Aspiration Award as set forth in the Agreement. The time of payment
     of the Aspiration Award and the form of such payment shall also be as set
     forth in the Agreement.

     8. RESTRICTED STOCK.  The Committee may grant Awards of Restricted Stock,
and may issue Shares of Restricted Stock in payment in respect of Aspiration
Awards or vested Performance Units (as hereinafter provided in Section 9(b)),
which shall be evidenced by an Agreement between the Company and the Grantee.
Each Agreement shall contain such restrictions, terms and conditions as the
Committee may, in its discretion, determine and (without limiting the generality
of the foregoing) such Agreements may require that an appropriate legend be
placed on Share certificates. Subject to the terms of the Plan, the Committee

                                       A-7
<PAGE>   31

may modify outstanding Awards of Restricted Stock. Notwithstanding the
foregoing, no modification of an award shall adversely alter or impair any
rights or obligations under the Agreement without the Grantee's consent. The
aggregate maximum number of Shares that may be awarded under a Restricted Stock
Award and an Award of Performance Shares and Performance Units to a Participant
during any fiscal year of the Company is 100,000 Shares and Units. Awards of
Restricted Stock shall be subject to the following terms and provisions:

          (a) RIGHTS OF GRANTEE.  Shares of Restricted Stock granted pursuant to
     an Award hereunder shall be issued in the name of the Grantee as soon as
     reasonably practicable after the Award is granted, provided that the
     Grantee has executed an Agreement evidencing the Award, the appropriate
     blank stock powers and, in the discretion of the Committee, an escrow
     agreement and any other documents which the Committee may require as a
     condition to the issuance of such Shares. If a Grantee shall fail to
     execute the documents which the Committee may require within the time
     period prescribed by the Committee at the time the Award is granted, the
     Award shall be null and void. At the discretion of the Committee, Shares
     issued in connection with a Restricted Stock Award shall be deposited
     together with the stock powers with an escrow agent designated by the
     Committee. Unless the Committee determines otherwise and as set forth in
     the Agreement, upon delivery of the Shares to the escrow agent, the Grantee
     shall have all of the rights of a stockholder with respect to such Shares,
     including the right to vote the Shares and to receive all dividends or
     other distributions paid or made with respect to the Shares.

          (b) NONTRANSFERABILITY.  Unless the Agreement provides otherwise,
     until any restrictions upon the Shares of Restricted Stock awarded to a
     Grantee shall have lapsed in the manner set forth in Section 8(c), such
     Shares shall not be sold, transferred or otherwise disposed of and shall
     not be pledged or otherwise hypothecated, nor shall they be delivered to
     the Grantee.

          (c) LAPSE OF RESTRICTIONS.

             (i) GENERALLY. Restrictions upon Shares of Restricted Stock awarded
        hereunder shall lapse at such time or times and on such terms and
        conditions as the Committee may provide in the Agreement.

             (ii) EFFECT OF CHANGE IN CONTROL. Unless the Agreement provides
        otherwise, in the event of a Change in Control, all restrictions upon
        any Shares of Restricted Stock (other than Performance Shares) shall
        lapse immediately and all such Shares shall become fully vested in the
        Grantee.

          (d) TERMINATION OF EMPLOYMENT. The Agreement shall set forth the terms
     and conditions that shall apply upon the termination of the Grantee's
     employment with the Company, a Subsidiary or a Division (including a
     forfeiture of Shares for which the restrictions have not lapsed upon
     Grantee's ceasing to be employed) as the Committee may, in its discretion,
     determine at the time the Award is granted or thereafter.

          (e) TREATMENT OF DIVIDENDS. At the time the Award of Shares of
     Restricted Stock is granted, the Committee may, in its discretion,
     determine that the payment to the Grantee of dividends, or a specified
     portion thereof, declared or paid on such Shares by the Company shall be
     (i) deferred until the lapsing of the restrictions imposed upon such Shares
     and (ii) held by the Company for the account of the Grantee until such
     time. In the event of such deferral, there shall be credited at the end of
     each year (or portion thereof) interest on the amount of the account at the
     beginning of the year at a rate per annum as the Committee, in its
     discretion, may determine. Payment of deferred dividends, together with
     interest accrued thereon, shall be made upon the lapsing of restrictions
     imposed on such Shares, and any dividends deferred (together with any
     interest accrued thereon) in respect of any Shares of Restricted Stock
     shall be forfeited upon the forfeiture of such Shares pursuant to Section
     8(d) or otherwise.

          (f) DELIVERY OF SHARES. Upon the lapse of the restrictions on Shares
     of Restricted Stock, the Committee shall cause a stock certificate to be
     delivered to the Grantee with respect to such Shares, free of all
     restrictions hereunder (except any restrictions under Section 17).

     9. PERFORMANCE AWARDS.

          (a) PERFORMANCE OBJECTIVES.  The Committee will select one or more of
     the Performance Measures listed on Appendix A attached hereto for purposes
     of Performance Awards under the Plan. Performance Measures may be in
     respect of the performance of the Company and its Subsidiaries (which may
     be on a consolidated basis), a Subsidiary or a Division, or any combination
     of
                                       A-8
<PAGE>   32

     the foregoing. Performance Awards may also include performance levels that
     relate to individual achievements or goals. Performance objectives may be
     absolute or relative and may be expressed in terms of a progression within
     a specified range, with the Grantee becoming vested in (i) a minimum
     percentage of such Performance Awards in the event the Minimum Acceptable
     Objective is met or, if surpassed, a greater percentage (ii) an
     intermediate percentage of such Performance Awards in the event the Good
     Objective is met or, if surpassed, a greater percentage and (iii) one
     hundred percent (100%) of such Performance Awards in the event the Maximum
     Realistic Objective is met or surpassed. In addition to adjustments
     provided for by the Agreement, the Committee may, in determining whether
     the performance levels have been met, adjust the financial results for a
     Performance Cycle to exclude the effect of unusual charges or income items,
     or other events (such as acquisition or divestitures and equity and other
     restructurings), which are distortive of financial results for the
     Performance Cycle; provided, that, with respect to Named Executive
     Officers, in determining financial results, items whose exclusion from
     consideration will increase the Award shall only have their effects
     excluded if they constitute "extraordinary" or "unusual" events or items
     under generally accepted accounting principles and all such events and
     items shall be excluded. The Committee shall also adjust the performance
     calculations to exclude the unanticipated effect on financial results of
     changes in the Code, or other tax laws, and the regulations thereunder. The
     Committee may decrease the amount of an Award otherwise payable if, in the
     Committee's view, the financial performance during the Performance Cycle
     justifies such adjustment, regardless of the extent to which the
     Performance Measure was achieved.

          The Agreement may provide the Committee with the right, during a
     Performance Cycle or after it has ended, to revise the performance levels
     for the Performance Measure and the Award amounts, if unforeseen events
     (including, without limitation, a Change in Capitalization, an equity
     restructuring, an acquisition or a divestiture) occur which have a
     substantial effect on the financial results and which in the judgment of
     the Committee make the application of the performance levels unfair unless
     a revision is made. For Named Executive Officers, such changes shall be
     made in a manner that is not inconsistent with Code Section 162(m).

          Except with respect to Named Executive Officers, the Committee may
     establish additional Performance Measures for purposes of Performance
     Awards under the Plan. Further, in the event that applicable tax and/or
     securities laws (including, but not limited to, Code Section 162(m) and
     Section 16 of the Exchange Act) change to permit Committee discretion to
     alter the governing Performance Measures for Named Executive Officers
     without obtaining stockholder approval of such changes, the Committee shall
     have sole discretion to make such changes without obtaining stockholder
     approval.

          The aggregate maximum number of Performance Units and Performance
     Shares and Shares of Restricted Stock a Participant may be awarded for any
     fiscal year of the Company shall be 100,000 Units and Shares.

          (b) PERFORMANCE UNITS.  The Committee may grant Performance Units, the
     terms and conditions of which shall be set forth in an Agreement between
     the Company and the Grantee. Each Performance Unit shall, contingent upon
     the attainment of specified performance objectives within the Performance
     Cycle, represent one (1) Share. Each Agreement shall specify the number of
     the Performance Units to which it relates, the performance objectives which
     must be satisfied in order for the Performance Units to vest, the
     Performance Cycle within which such objectives must be satisfied, and the
     form of payment in respect of vested Performance Units.

             (i) VESTING AND FORFEITURE.  A Grantee shall become vested with
        respect to the Performance Units to the extent that the performance
        objectives set forth in the Agreement are satisfied for the Performance
        Cycle. Subject to Section 9(d) hereof, if the Minimum Acceptable
        Objective specified in the Agreement is not satisfied for the applicable
        Performance Cycle, the Grantee's rights with respect to the Performance
        Units shall be forfeited.

             (ii) PAYMENT OF AWARDS.  Payment of Performance Units to Grantees
        in respect of vested Performance Units shall be made within sixty (60)
        days after the last day of the Performance Cycle to which such Award
        relates. Subject to Section 9(d), such payments may be made entirely in
        Shares, entirely in cash, or in such combination of Shares and cash as
        the Committee in its discretion, shall determine at any time prior to
        such payment, provided, however, that if the Committee in its discretion
        determines to make such payment entirely or partially in Shares of
        Restricted Stock, the Committee must determine the extent to which such
        payment will be in Shares of Restricted Stock at the time the Award is
        granted. Except as provided in Section 9(d),

                                       A-9
<PAGE>   33

        and except as the Committee otherwise provides in the Agreement, if
        payment is made in the form of cash, the amount payable in respect of
        any Share shall be equal to the average of the Fair Market Value of such
        Share for the last ten trading days of the Performance Cycle.

             (iii) TERMINATION OF EMPLOYMENT.  The Agreement shall set forth the
        terms and conditions of the Award of Performance Units upon the
        termination of the Grantee's employment with the Company, a Subsidiary,
        or a Division (including a Grantee's ceasing to be employed by a
        Subsidiary or Division as a result of the sale of such Subsidiary or
        Division or an interest in such Subsidiary or Division) as the Committee
        may, in its discretion, determine at the time the Award is granted or
        thereafter.

          (c) PERFORMANCE SHARES.  The Committee, in its discretion, may grant
     Awards of Performance Shares and shall be evidenced by an Agreement between
     the Company and the Grantee. Each Agreement shall contain such
     restrictions, if any, and the terms and conditions as the Committee may, in
     its discretion, require, and (without limiting the generality of the
     foregoing) such Agreements may require that an appropriate legend be placed
     on Share certificates. Awards of Performance Shares shall be subject to the
     following terms and provisions:

             (i) RIGHTS OF GRANTEE.  The Committee shall provide at the time an
        Award of Performance Shares is made, the time or times at which the
        Performance Shares granted pursuant to such Award hereunder shall be
        issued in the name of the Grantee; provided, however, that no
        Performance Shares shall be issued until the Grantee has executed an
        Agreement evidencing the Award, the appropriate blank stock powers and,
        in the discretion of the Committee, an escrow agreement and any other
        documents which the Committee may require as a condition to the issuance
        of such Performance Shares. If a Grantee shall fail to execute the
        documents which the Committee may require within the time period
        prescribed by the Committee at the time the Award is granted, the Award
        shall be null and void. At the discretion of the Committee, Shares
        issued in connection with an Award of Performance Shares shall be
        deposited together with the stock powers with an escrow agent designated
        by the Committee. Except as restricted by the terms of the Agreement,
        upon delivery of the Shares to the escrow agent, the Grantee shall have,
        in the discretion of the Committee, all of the rights of a stockholder
        with respect to such Shares, including the right to vote the shares and
        to receive all dividends or other distributions paid or made with
        respect to the shares.

             (ii) NONTRANSFERABILITY.  Unless the Agreement provides otherwise,
        until any restrictions upon the Performance Shares awarded to a Grantee
        shall have lapsed in the manner set forth in Sections 9(c)(3) or 9(d),
        such Performance Shares shall not be sold, transferred or otherwise
        disposed of and shall not be pledged or otherwise hypothecated, nor
        shall they be delivered to the Grantee. The Committee may also impose
        such other restrictions and conditions on the Performance Shares, if
        any, as it deems appropriate.

             (iii) LAPSE OF RESTRICTIONS.  Subject to Section 9(d), restrictions
        upon Performance Shares awarded hereunder shall lapse and such
        Performance Shares shall become vested at such time or times and on such
        terms, conditions and satisfaction of performance objectives as the
        Committee may, in its discretion, determine at the time an Award is
        granted.

             (iv) TERMINATION OF EMPLOYMENT.  The Agreement shall set forth the
        terms and conditions of the Award of Performance Shares upon the
        termination of the Grantee's employment with the Company, a Subsidiary
        or a Division (including a Grantee's ceasing to be employed by a
        Subsidiary or Division as a result of the sale of such Subsidiary or
        Division or an interest in such Subsidiary or Division) as the Committee
        may, in its discretion, determine at the time the Award is granted or
        thereafter.

             (v) TREATMENT OF DIVIDENDS.  At the time the Award of Performance
        Shares is granted, the Committee may, in its discretion, determine that
        the payment to the Grantee of dividends, or a specified portion thereof,
        declared or paid on Performance Shares issued by the Company to the
        Grantee shall be (i) deferred until the lapsing of the restrictions
        imposed upon such Performance Shares and (ii) held by the Company for
        the account of the Grantee until such time. In the event of such
        deferral, there shall be credited at the end of each year (or portion
        thereof) interest on the amount of the account at the beginning of the
        year at a rate per annum as the Committee, in its discretion, may
        determine. Payments of deferred dividends, together with interest

                                      A-10
<PAGE>   34

        accrued thereon as aforesaid, shall be made upon the lapsing of
        restrictions imposed on such Performance Shares, except that any
        dividends deferred (together with any interest accrued thereon) in
        respect of any Performance Shares shall be forfeited upon the forfeiture
        of such Performance Shares pursuant to Section 9(c)(iv) or otherwise.

             (vi) DELIVERY OF SHARES.  Upon the lapse of the restrictions on
        Performance Shares awarded hereunder, the Committee shall cause a stock
        certificate to be delivered to the Grantee with respect to such Shares,
        free of all restrictions hereunder.

          (d) EFFECT OF CHANGE IN CONTROL.  Unless the Agreement provides
     otherwise, in the event of a Change in Control:

             (i) With respect to the Performance Units, the Grantee shall (i)
        become vested in a percentage of Performance Unit as determined by the
        Committee at the time of the Award of such Performance Units and as set
        forth in the Agreement and (ii) be entitled to receive in respect of all
        Performance Units which become vested as a result of a Change in
        Control, a cash payment within ten (10) days after such Change in
        Control equal to the product of the Adjusted Fair Market Value of a
        Share multiplied by the number of Performance Units which become vested
        in accordance with this Section 9(d); and

             (ii) With respect to the Performance Shares, all restrictions shall
        lapse immediately on all or a portion of the Performance Shares as
        determined by the Committee at the time of the Award of such Performance
        Shares and as set forth in the Agreement.

          (e) NONTRANSFERABILITY.  Unless the Agreement provides otherwise, no
     Performance Awards shall be transferable by the Grantee otherwise than by
     will or the laws of descent and distribution.

          (f) DEFINITIONS.  For purposes of Performance Awards, the following
     definitions shall apply:

             (i) "GOOD OBJECTIVE" means a challenging and above average level of
        performance of the Company, a Subsidiary or a Division during a
        Performance Cycle for which a performance Award is granted, as
        determined by the Committee at the time such Performance Award is
        granted.

             (ii) "MAXIMUM REALISTIC OBJECTIVE" means an excellent level of
        performance of the Company, a Subsidiary or a Division during a
        Performance Cycle for which a Performance Award is granted, as
        determined by the Committee at the time such Performance Award is
        granted.

             (iii) "MINIMUM ACCEPTABLE OBJECTIVE" means a minimum level of
        performance of the Company, a Subsidiary or a Division during a
        Performance Cycle for which a Performance Award is granted, as
        determined by the Committee at the time such Performance Award is
        granted.

     10. LOANS.

          (a) The Company or any Subsidiary may make loans to a Grantee or
     Optionee in connection with the exercise of an Option, subject to the
     following terms and conditions and such other terms and conditions not
     inconsistent with the Program including the rate of interest, if any, as
     the Committee shall impose from time to time.

          (b) No loan made under the Program shall exceed the sum of (i) the
     aggregate purchase price payable pursuant to the Option with respect to
     which the loan is made, plus (ii) the amount of the reasonably estimated
     income taxes payable by the Optionee or Grantee with respect to the Option
     or Award. In no event may any such loan exceed the Fair Market Value, at
     the date of exercise, of any such Shares.

          (c) No loan shall have an initial term exceeding ten (10) years;
     provided, however, that loans under the Program shall be renewable at the
     discretion of the Committee.

          (d) Loans under the Program may be satisfied by an Optionee or
     Grantee, as determined by the Committee, in cash or, with the consent of
     the Committee, in whole or in part by the transfer to the Company of Shares
     whose Fair Market Value on the date preceding the date of such payment is
     equal to the cash amount for which such Shares are transferred.

          (e) A loan shall be secured by a pledge of Shares with a Fair Market
     Value of not less than the principal amount of the loan. After partial
     repayment of a loan, pledged Shares no longer required as

                                      A-11
<PAGE>   35

     security may be released into escrow or pursuant to the terms of the
     Option, Award or escrow agreement to the Optionee or Grantee.

     11. ADJUSTMENT UPON CHANGES IN CAPITALIZATION.

          (a) In the event of a Change in Capitalization, the Committee shall
     conclusively determine the appropriate adjustments, if any, to the maximum
     number and class of Shares or other stock or securities with respect to
     which Options or Awards may be granted under the Program, the number and
     class of Shares or other stock or securities which are subject to
     outstanding Options or Awards granted under the Program, and the purchase
     price therefor, if applicable.

          (b) Any such adjustment in the Shares or other stock or securities
     subject to outstanding Incentive Stock Options (including any adjustments
     in the purchase price) shall be made in such manner as not to constitute a
     modification as defined by Section 424(h)(3) of the Code and only to the
     extent otherwise permitted by Sections 422 and 424 of the Code.

          (c) If, by reason of a Change in Capitalization, a Grantee of an Award
     shall be entitled to, or an Optionee shall be entitled to exercise an
     Option with respect to, new, additional or different shares of stock,
     securities, Aspiration Awards, Performance Units or Performance Shares
     (other than rights or warrants to purchase securities), such new,
     additional or different shares shall thereupon be subject to all of the
     conditions, restrictions and performance criteria which were applicable to
     the Aspiration Awards, Performance Units or Performance Shares pursuant to
     the Award or Shares subject to the Option, as the case may be, prior to
     such Change in Capitalization.

     12. EFFECT OF CERTAIN TRANSACTIONS.  Subject to Sections 6(h), 7(g),
8(c)(ii) and 9(d), in the event of (i) the liquidation or dissolution of the
Company or (ii) a merger or consolidation of the Company (a "Transaction"), the
Plan and the Options and Awards issued hereunder shall continue in effect in
accordance with their respective terms and each Optionee and Grantee shall be
entitled to receive in respect of each Share subject to any outstanding Options
or Awards, as the case may be, upon exercise of any Option or Award or payment
or transfer in respect of any Award, the same number and kind of stock,
securities, cash, property, or other consideration that each holder of a Share
was entitled to receive in the Transaction in respect of a Share.

     13. RELEASE OF FINANCIAL INFORMATION.  A copy of the Company's annual
report to stockholders shall be delivered to each Optionee and Grantee at the
time such report is distributed to the Company's stockholders. Upon reasonable
request the Company shall furnish as soon as reasonably practicable, to each
Optionee and Grantee a copy of its most recent annual report and each quarterly
report and current report filed under the Exchange Act since the end of the
Company's prior fiscal year.

     14. TERMINATION AND AMENDMENT OF THE PLAN.

          (a) The Plan shall terminate on September 18, 2006, and no Option or
     Award may be granted thereafter. The Board may sooner terminate or amend
     the Plan (other than to reduce the rights of Optionees and Grantees, as the
     case may be, under Sections 6(h), 7(g), 8(c)(ii) and 9(d), at any time and
     from time to time; provided, however, that to the extent legally required,
     no amendment shall be effective unless approved by the stockholders of the
     Company in accordance with applicable law and regulations at an annual or
     special meeting.

          (b) Except as provided in Sections 11 and 12 hereof, rights and
     obligations under any Option or Award granted before any amendment of the
     Plan shall not be adversely altered or impaired by such amendment, except
     with the consent of the Optionee or Grantee, as the case may be.

     15. NONEXCLUSIVITY OF THE PLAN.  The adoption of the Plan by the Board
shall not be construed as amending, modifying or rescinding any previously
approved incentive arrangement or as creating any limitations on the power of
the Board to adopt such other incentive arrangements as it may deem desirable,
including, without limitation, the granting of stock options otherwise than
under the Plan, and such arrangements may be either applicable generally or only
in specific cases.

     16. LIMITATION OF LIABILITY.  As illustrative of the limitations of
liability of the Company, but not intended to be exhaustive thereof, nothing in
the Plan shall be construed to:

          (a) give any person any right to be granted an Option or Award other
     than at the sole discretion of the Committee;

                                      A-12
<PAGE>   36

          (b) give any person any rights whatsoever with respect to Shares
     except as specifically provided in the Plan;

          (c) limit in any way the right of the Company to terminate the
     employment of any person at any time (with or without Cause); or

          (d) be evidence of any agreement or understanding, expressed or
     implied, that the Company will employ any person in any particular position
     at any particular rate of compensation or for any particular period of
     time.

     17. REGULATION AND OTHER APPROVALS; GOVERNING LAW.

          (a) This Plan and the rights of all persons claiming hereunder shall
     be construed and determined in accordance with the laws of the State of
     Delaware without giving effect to the conflicts of laws principles thereof,
     except to the extent that such law is preempted by federal law.

          (b) The obligation of the Company to sell or deliver Shares with
     respect to Options and Awards granted under the Plan shall be subject to
     all applicable laws, rules and regulations, including all applicable
     federal and state securities laws, and the obtaining of all such approvals
     by governmental agencies as may be deemed necessary or appropriate by the
     Committee.

          (c) The Plan is intended to comply with Rule 16b-3 promulgated under
     the Exchange Act and the Committee shall interpret and administer the
     provisions of the Plan or any Agreement in a manner consistent therewith.
     Any provisions inconsistent with such Rule shall be inoperative and shall
     not affect the validity of the Plan.

          (d) The Board may make such changes as may be necessary or appropriate
     to comply with the rules and regulations of any government authority, or to
     obtain for Eligible Employees granted Incentive Stock Options the tax
     benefits under the applicable provisions of the code and regulations
     promulgated thereunder.

          (e) Each Option and Award is subject to the requirement that, if at
     any time the Committee determines, in its discretion, that the listing,
     registration or qualification of Shares issuable pursuant to the Plan is
     required by 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 grant of an Option
     or the issuance of Shares, no Options shall be granted or payment made or
     Shares issued, in whole or in part, unless listing, registration,
     qualification, consent or approval has been effected or obtained free of
     any conditions as acceptable to the Committee.

          (f) Notwithstanding anything contained in the Plan to the contrary, in
     the event that the disposition of Shares acquired pursuant to the Plan is
     not covered by a then current registration statement under the Securities
     Act of 1933, as amended, and is not otherwise exempt from such
     registration, such Shares shall be restricted against transfer to the
     extent required by the Securities Act of 1933, as amended, and Rule 144 or
     other regulations thereunder. The Committee may require any individual
     receiving Shares pursuant to the Plan, as a condition precedent to receipt
     of such Shares (including upon exercise of an Option), to represent and
     warrant to the Company in writing that the Shares acquired by such
     individual are acquired without a view to any distribution thereof and will
     not be sold or transferred other than pursuant to an effective registration
     thereof under said Act or pursuant to an exemption applicable under the
     Securities Act of 1933, as amended, or the rules and regulations
     promulgated thereunder. The certificates evidencing any of such Shares
     shall be appropriately legended to reflect their status as restricted
     securities as aforesaid.

          (g) In the event that changes are made to Code Section 162(m) to
     permit greater flexibility with respect to any Award or Option under the
     Plan, the Committee may, subject to this Section 17, make any adjustments
     it deems appropriate in such Award or Option.

     18. MISCELLANEOUS.

          (a) MULTIPLE AGREEMENTS.  The terms of each Option or Award may differ
     from other Options or Awards granted under the Plan at the same time, or at
     some other time. The Committee may also grant more than one Option or Award
     to a given Eligible Employee during the term of the Plan, either in
     addition to, or in substitution for, one or more Options or Awards
     previously granted to that Eligible Employee. The grant of multiple Options
     and/or Awards may be evidenced by a single Agreement or multiple
     Agreements, as determined by the Committee.

                                      A-13
<PAGE>   37

          (b) WITHHOLDING OF TAXES.

             (1) The Company shall have the right to deduct from any
        distribution of cash to any Optionee or Grantee, an amount equal to the
        federal, state and local income taxes and other amounts as may be
        required by law to be withheld (the "Withholding Taxes") with respect to
        any Option or Award. If an Optionee or Grantee is entitled to receive
        Shares upon exercise of an Option or pursuant to an Award, the Optionee
        or Grantee shall pay the Withholding Taxes to the Company prior to the
        issuance, or release from escrow, of such Shares. In satisfaction of the
        Withholding Taxes to the Company, the Optionee or Grantee may make an
        irrevocable written election (the "Tax Election"), which may be accepted
        or rejected in the discretion of the Committee, to have withheld a
        portion of the Shares issuable to him or her upon exercise of the Option
        or pursuant to an Award having an aggregate Fair Market Value equal to
        the Withholding Taxes.

             (2) If an Optionee makes a disposition, within the meaning of
        Section 424(c) of the Code and regulations promulgated thereunder, of
        any Share or Shares issued to him pursuant to his exercise of an
        Incentive Stock Option within the two-year period commencing on the day
        after the date of the grant or within the one-year period commencing on
        the day after the date of transfer of such Share or Shares to the
        Optionee pursuant to such exercise, the Optionee shall, within ten (10)
        days of such disposition, notify the Company thereof, by delivery of
        written notice to the Company at its principal executive office, and
        immediately deliver to the Company the amount of Withholding Taxes.

          (c) DESIGNATION OF BENEFICIARY.  To the extent applicable to the type
     of Award, each Grantee (other than an Optionee) may designate a person or
     persons to receive in the event of his or her death, any Award or any
     amount payable pursuant thereto, to which he or she would then be entitled
     under the terms of the Plan. Such designation will be made upon forms
     supplied by and delivered to the Company and may be revoked in writing.

          (d) DEFERRAL.  The Committee may permit a Participant to defer to
     another plan or program such Participant's receipt of Shares or cash that
     would otherwise be due to such Participant by virtue of the exercise of an
     Option, earning of an Aspiration Award, the vesting of Restricted Stock or
     the earning of Performance Awards. If any such deferral election is
     required or permitted, the Committee shall, in its sole discretion,
     establish rules and procedures for such payment deferrals.

     19. EFFECTIVE DATE.  This amended and restated Plan shall be effective
January 5, 2000 and shall apply to Awards made on or after that date. Except
where the Committee provides otherwise, Awards made prior to that date shall
remain subject to prior provisions of the Plan.
