COMPENSATION OF DIRECTORS



     Nonemployee directors of Brooks receive $1,000 cash compensation annually,
in addition to expenses reasonably incurred, for service on the board.
Nonemployee directors who are members of the audit or compensation committees
receive $4,000 per year for their services on each committee. If the merger with
PRI is approved, the annual cash compensation for nonemployee directors will
increase to $20,000 for service on the board, and $5,000 for service on each
committee. Each nonemployee director is granted options to purchase 10,000
shares of Brooks common stock on the date he is first elected a director and
options to purchase 5,000 shares of common stock on July 1 of each year
thereafter pursuant to Brooks' 1993 nonemployee director stock option plan. The
board of directors has amended the directors plan to increase the initial and
annual grants thereunder to 25,000 and 10,000 shares, of Brooks common stock,
respectively, and to provide an additional one-time grant of 15,000 shares to
existing nonemployee directors, subject to stockholder approval. Employee
directors may elect to participate in Brooks' 1995 employee stock purchase plan
and may be granted options under Brooks' 1992 combination stock option plan or
Brooks' 2000 combination stock option plan. Nonemployee directors may be granted
options under the 1992 combination stock option plan.



INDEMNIFICATION AGREEMENTS



     Brooks has entered into indemnification agreements with each of its
directors and anticipates that it will enter into similar agreements with any
future directors. Generally, the indemnification agreements attempt to provide
the maximum protection permitted by Delaware law with respect to indemnification
of the director.



     The indemnification agreements provide that Brooks will pay certain amounts
incurred by a director in connection with any civil or criminal action or
proceeding, specifically including actions by or in the name of Brooks
(derivative suits) where the individual's involvement is by reason of the fact
that he is or was a director or officer. Such amounts include, to the maximum
extent permitted by law, attorney's fees, judgments, civil or criminal fines,
settlement amounts, and other expenses customarily incurred in connection with
legal proceedings. Under the indemnification agreements, a director will receive
indemnification unless he is found not to have acted in good faith and in a
manner he reasonably believed to be in the best interests of Brooks.



EMPLOYMENT CONTRACTS



     Robert J. Therrien.  Effective October 1, 2001, Brooks entered into an
employment agreement with Robert J. Therrien, its president and chief executive
officer, that replaced Mr. Therrien's former agreement, which expired on
September 30, 2001. Under the agreement, Mr. Therrien will continue in his role
as president and chief executive officer of Brooks for four years. If Mr.
Therrien identifies his successor as president and chief executive officer, then
Mr. Therrien may become chairman of the board of directors.



     The agreement entitles Mr. Therrien to a minimum annual salary of $500,000.
Mr. Therrien's minimum salary will increase to $615,000 upon completion of the
proposed merger with PRI. The agreement entitles Mr. Therrien to annual
discretionary bonuses determined by the compensation committee.



     The agreement provides that Mr. Therrien will receive monthly supplemental
retirement benefits equal to Mr. Therrien's monthly salary in effect as of the
date he terminates employment with Brooks. The monthly supplemental retirement
benefits will be paid for a period equal to one and one-half times the number of
months Mr. Therrien serves Brooks after October 1, 1994. For purposes of
calculating these benefits the contract generally provides that Mr. Therrien's
annual salary will be no less than $500,000 ($41,667 monthly). As of September
30, 2001, Mr. Therrien had seven years, or 84 months, of credited service. In
the event of Mr. Therrien's death or permanent disability, he or his estate has
the option of receiving his supplemental retirement compensation over a period
of not less than four years. If the merger with PRI is completed, Mr. Therrien's
minimum annual salary for purposes of calculating his supplemental retirement
benefits will increase to $615,000 ($51,250 monthly) and his supplemental
retirement benefit will be paid in a single, lump-sum payment.


                                        5



     The table below describes the annual supplemental retirement benefits Mr.
Therrien would receive given different assumptions regarding his minimum annual
salary and time of service after October 1, 1994.

     Brooks has established a rabbi trust in connection with Mr. Therrien's
supplemental retirement benefits and purchased two insurance policies to fund
the payment of the supplemental retirement benefits. Currently, the rabbi trust
holds two whole life insurance policies with combined death benefits of
$5,000,000 and a combined cash surrender value of approximately $2,300,000. The
rabbi trust assets are unsecured and subject to the claims of creditors.



     In addition, Mr. Therrien will participate in all employee welfare and
benefit plans normally offered to other Brooks executives, except that he will
not participate in any retirement plan other than Brooks' 401(k) plan and will
only receive the supplemental retirement benefits. Mr. Therrien is entitled to
the use of an automobile during the term of his agreement.



     The employment agreement provides that if Mr. Therrien's employment is
terminated without "cause," or if Mr. Therrien terminates his employment for
"good reason," he will be entitled to receive his annual salary and bonus for
the remaining term of the agreement, continued life insurance coverage until
October 1, 2005 and medical, dental and vision insurance for life. The
employment agreement provides that cause means Mr. Therrien has: (i) habitually
neglected his material duties under the agreement; (ii) perpetrated fraud or
embezzlement; or (iii) been finally adjudicated to have committed a felony. The
agreement provides that good reason means Mr. Therrien has suffered, without his
consent, a reduction in his status at Brooks either through a demotion in his
duties or a change in his title.



     If Mr. Therrien is terminated for cause, he will only be entitled to
receive his then accrued salary and accrued vacation days and will forfeit all
benefits payable under the supplemental retirement benefit.



     In addition, if Mr. Therrien's employment is terminated or he resigns
following a change of control, as defined in the agreement, then Brooks is
obligated to pay Mr. Therrien a lump sum severance payment equal to three times
his base salary and bonus. Mr. Therrien is also entitled to receive other
payments and benefits including continuation of life insurance coverage until
October 1, 2005 and medical, dental and vision insurance for life.



     In the event of Mr. Therrien's termination or resignation following a
change of control, his resignation for good reason or his termination without
cause, his stock options will immediately vest and remain exercisable until the
earlier of 24 months following his termination or the expiration of the option
term. However, the extension of the option exercise period will not apply to any
options granted prior to September 30, 2001, if such extension would result in a
charge to earnings or other adverse accounting consequence.



     Mr. Therrien is entitled to reimbursement of any "parachute" excise tax
imposed on payments under the employment agreement.


                                        6



     Mr. Therrien's employment agreement also contains noncompetition,
nonsolicitation and confidentiality provisions. The noncompetition and
nonsolicitation provisions prohibit Mr. Therrien from directly or indirectly
competing with, or soliciting employees of, Brooks so long as he is an employee
of Brooks and for a period of two years thereafter.



     Ellen B. Richstone.  In October 1998, Brooks entered into an employment
agreement with Ellen B. Richstone, its Senior Vice President, Finance and
Administration and Chief Financial Officer, which entitles Ms. Richstone to a
base salary of $225,000 per year, and to participation in the discretionary
executive bonus program, as well as a guaranteed annual bonus of $10,000 and a
one-time "signing" bonus of $40,000. In the event Ms. Richstone's employment
with Brooks is terminated for reasons other than cause, the agreement provides
that Ms. Richstone will receive either one year of her then current base salary
or $250,000, whichever is greater, and the acceleration of all of her
outstanding options.



     The agreement also provides Ms. Richstone with certain other benefits,
including an automobile allowance of $15,000 per year, the opportunity to
participate in insurance plans, and other employment benefits as may be
generally available to senior executives of Brooks. Brooks has entered into an
indemnification agreement with Ms. Richstone on the same terms as Brooks'
directors. See "-- Indemnification Agreements."



CHANGE IN CONTROL ARRANGEMENTS



     On November 11, 1999, Brooks entered into change of control agreements with
certain key employees, including each of its named executive officers other than
Mr. Therrien, whose employment contract offers change of control benefits. The
board of directors determined that it was in the best interests of Brooks and
its stockholders to assure that Brooks have the continued dedication of these
persons, notwithstanding the possibility, threat, or occurrence of a change in
control of Brooks. The purpose of the agreements is to diminish the inevitable
distraction for these persons caused by the personal uncertainties and risks
created by a pending or threatened change of control and to encourage their full
attention and dedication to Brooks currently and in the event of any threatened
or pending change of control. The agreements have terms of five years and
automatically renew in five-year increments unless a party to the agreement
objects in writing in advance of the renewal. The agreements provide that in the
event of a change of control these persons will retain their then current
compensation and benefits for the lesser of one year or until terminated for
cause. The agreements also provide that the position of such person upon a
change of control shall be at least commensurate with the highest position held
by such person prior to the change of control, after completion of a six month
transitional period. Under the agreements, if the employee is terminated other
than for cause, disability or death or if the employee resigns for good reason
the employee is entitled to one year of salary in a lump sum payment and the
continuation of certain benefits for 18 months. Under Ms. Richstone's change of
control agreement, all of her options will vest immediately and she will receive
a lump sum payment equal to the greater of $250,000 or her then current base
salary if she is terminated other than for cause, disability or death or resigns
for good reason in connection with a change of control of Brooks. For purposes
of the agreements, cause means willful acts of dishonesty, repeated breaches by
the employee of the agreement or the conviction of a felony involving moral
turpitude. Good reason includes diminution of the responsibility or position of
the employee, Brooks' breach of the agreement or the involuntary relocation of
the employee.



INDEMNIFICATION AGREEMENTS



     In February 2000, Brooks entered into indemnification agreements with each
of its executive officers not previously covered by such agreements. The
indemnification agreements provide that Brooks will pay certain amounts incurred
by an officer in connection with any civil or criminal action or proceeding,
specifically including actions by or in the name of Brooks where the
individual's involvement is by reason of the fact that he is or was an officer.
Such amounts include, to the maximum extent permitted by law, attorney's fees,
judgments, civil or criminal fines, settlement amounts, and other expenses
customarily incurred in connection with legal proceedings. Under the
indemnification agreements, an officer will receive indemnification unless he or
she is found not to have acted in good faith and in a manner he or she
reasonably believed to be in the best interests of Brooks.

                                        7



BONUS PLAN



     Brooks maintains a bonus program for employees, including executive
officers, under which such employees may be awarded cash bonuses based upon
Brooks' overall financial performance.



STOCK PURCHASE PLAN



     In February 1996, Brooks adopted the 1995 employee stock purchase plan to
provide employees of Brooks with additional incentives by permitting them to
acquire an equity interest in Brooks through the purchase of shares of Brooks
common stock. The stock purchase plan is intended to qualify as an "employee
stock purchase plan" under Section 423 of the Internal Revenue Code.



STOCK OPTION PLANS



     The following tables set forth certain information with respect to the
stock options granted to and exercised by the named executive officers during
fiscal 2001 and the aggregate number of and value of options exercisable and

(1)The "value realized" reflects the appreciation on the date of exercise (based
   on the excess of the fair market value of the Brooks common stock on the date
   of exercise over the exercise price). However, because the named executive
   officers may keep the shares they acquired upon the exercise of the options
   (or sell them at a different price), these amounts do not necessarily reflect
   cash realized upon the sale of those shares.



(2)Based on the closing price of the Brooks common stock on September 28, 2001
   on the Nasdaq National Market of $26.59, minus the respective option exercise
   prices.



1992 COMBINATION STOCK OPTION PLAN



     Under Brooks' 1992 combination stock option plan, which is administered by
the compensation committee of the Brooks board of directors, Brooks may grant
both incentive stock options intended to qualify under Section 422 of the
Internal Revenue Code, and other options which are not qualified as incentive
stock options. Incentive stock options may only be granted to persons who are
employees of Brooks at the time of grant, which may include officers and
directors who are also employees. Nonqualified stock options may be granted to
persons who are officers, directors or employees of or consultants or advisors
to Brooks, or persons who are in a position to contribute to the long-term
success and growth of Brooks at the time of grant. Options granted under the
1992 plan generally vest over a period of four years. A total of 1,950,000
shares of Brooks common stock were reserved for issuance under the 1992 plan. Of
these shares, options on 727,305 shares have been granted and are outstanding
and 1,884 shares remain available for grant as of December 7, 2001. In order to
align the 1992 plan with its current practices, in January 2000 the board of
directors amended the 1992 plan to eliminate Brooks' ability to grant restricted
stock under the 1992 plan and to require that all options be granted with
exercise prices not less than fair market value.



1993 NONEMPLOYEE DIRECTOR STOCK OPTION PLAN



     The purpose of the 1993 nonemployee director stock option plan is to
attract and retain the services of experienced and knowledgeable independent
directors of Brooks for the benefit of Brooks and its stockholders and to
provide additional incentives for such independent directors to continue to work
for the best interests of Brooks and its stockholders.



1998 EMPLOYEE EQUITY INCENTIVE PLAN



     The purpose of the 1998 employee equity incentive plan, adopted by the
board of directors of Brooks in April 1998, is to attract and retain employees
and provide an incentive for them to assist Brooks to achieve long-range
performance goals, and to enable them to participate in the long-term growth of
Brooks. All employees of Brooks, other than its officers and directors,
(including contractors, consultants, service providers or others) who are in a
position to contribute to the long-term success and growth of Brooks, are
eligible to participate in the 1998 plan. As of September 30, 2001, 3,550,000
shares of Brooks common stock were reserved for issuance under the 1998 plan. On
October 1, 2001, the board amended the 1998 plan to increase


                                        9



the total number of shares reserved for issuance thereunder to 4,750,000. On
that date, the board granted options to purchase 1,605,440 shares under the 1998
plan. Of the shares reserved for issuance under the 1998 plan, options on
4,243,859 shares have been granted and are outstanding and 248,419 shares remain
available for grant as of December 7, 2001. In order to align the 1998 plan with
its current practices, in January 2000, the board of directors amended the 1998
plan to eliminate Brooks' ability to award nonqualified stock options with
exercise prices at less than fair market value.



2000 COMBINATION STOCK OPTION PLAN



     The purposes of the 2000 combination stock option plan are to attract and
retain employees and to provide an incentive for them to assist Brooks to
achieve long-range performance goals and to enable them to participate in the
long-term growth of Brooks. Under the 2000 plan Brooks may grant (i) incentive
stock options intended to qualify under Section 422 of the Internal Revenue
Code, and (ii) options that are not qualified as incentive stock options.



COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION



     The compensation committee of the board of directors consists of Messrs.
Emerick and Khoury. Neither Mr. Emerick nor Mr. Khoury is or was formerly an
officer or employee of Brooks. Mr. Therrien, the president and chief executive
officer of Brooks, has been delegated the authority to grant options to purchase
not more than 9,000 shares of Brooks common stock per employee per fiscal year
to employees who are not executive officers on terms that are consistent with
the 1992 plan, the 1998 plan and the 2000 plan. Mr. Therrien granted options to
purchase an aggregate of 6,750 shares of Brooks common stock in fiscal 2001.
Prior to November 1994, all decisions regarding compensation of executive
officers were made by the entire board of directors.



ITEM 12.  SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT



     The following table provides information regarding the beneficial ownership
of Brooks common stock as of December 7, 2001 by:



     - each director of Brooks;



     - each nominee for director of Brooks;



     - each person known by Brooks to be the beneficial owner of more than 5% of
      its common stock;



     - Brooks' named executive officers;



     - all current executive officers and directors of Brooks as a group; and



     - each of Mitchell G. Tyson and Kenneth M. Thompson (if the merger with PRI
      is completed, Brooks plans to appoint Messrs. Tyson and Thompson to its
      board of directors).



     Beneficial ownership is determined according to the rules of the SEC.
Except as indicated by footnotes and subject to community property laws, where
applicable, the persons named below have sole voting and investment power with
respect to all shares shown as beneficially owned by them. The "right to
acquire" column reflects beneficial ownership of shares subject to options that
may be exercised within 60 days after December 7, 2001.



     The percentage beneficially owned by each person is based upon 19,923,724
shares of Brooks common stock outstanding as of December 7, 2001. The shares
that a person has the right to acquire are deemed to be outstanding solely for
purposes of calculating that person's percentage ownership.



     The current directors and executive officers of Brooks have entered into
voting agreements with PRI in which they agreed to vote all of their shares of
Brooks common stock in favor of the approval and adoption of the merger
agreement and have executed irrevocable proxies with respect to their shares in
favor of PRI. Likewise, the current directors and executive officers of PRI have
entered into voting agreements with Brooks in which they agreed to vote all of
their shares of PRI common stock in favor of the approval and adoption of the
merger agreement and have executed irrevocable proxies with respect to their
shares in favor of Brooks.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS



LAM RESEARCH CORPORATION



     Purchases by Lam accounted for approximately 12%, 11% and 7% of Brooks'
revenues during fiscal 1999, 2000 and 2001, respectively. From 1982 until
January 2001, Roger D. Emerick, who serves on Brooks' board of directors, served
as a director on Lam's board of directors. There is no agreement or arrangement
requiring the election of Mr. Emerick or any other representative of Lam to
serve as a director of Brooks.



     Sales to Lam have been made in the ordinary course of Brooks' business, and
Brooks believes that the terms of its transactions with Lam have not been less
favorable to Brooks than could have been obtained from a party unaffiliated with
Brooks purchasing products of similar types and at comparable volumes.



FAIRCHILD SEMICONDUCTOR INTERNATIONAL, INC.



     On June 11, 2001, Brooks appointed Joseph Martin to its board of directors.
Mr. Martin also serves on the board of Fairchild Semiconductor International, a
customer of Brooks. Revenues generated from Fairchild Semiconductor for the
period from June 11, 2001 through September 30, 2001 were not material to
Brooks' consolidated results for fiscal 2001. There is no agreement or
arrangement requiring the election of Mr. Martin or any other representative of
Fairchild Semiconductor to serve as a director of Brooks.



     Sales to Fairchild Semiconductor have been made in the ordinary course of
Brooks' business, and Brooks believes that the terms of the transactions with
Fairchild Semiconductor have not been less favorable to Brooks than could have
been obtained from a party unaffiliated with Brooks purchasing products of
similar types and at comparable volumes.



JENOPTIK STOCKHOLDER AGREEMENT



     On September 30, 1999, Brooks acquired substantially all of the assets and
assumed certain of the liabilities of the Infab Division of Jenoptik AG in
exchange for 914,286 shares of Brooks common stock issued to Jenoptik's
subsidiary M+W, subject to a 5% holdback and to adjustment. As part of this
acquisition, Brooks appointed Juergen Giessmann, a member of the board of
directors of Jenoptik, to Brooks' board of directors pursuant to a stockholder
agreement dated September 30, 1999 among Brooks, Jenoptik, M+W, and Robert J.
Therrien. Under the stockholder agreement, until Jenoptik no longer holds all
its shares purchased from Brooks in this transaction, or until September 30,
2004, whichever occurs first, Brooks agreed to nominate a reasonably acceptable
candidate of Jenoptik to Brooks' board of directors in each election of Brooks'
directors, and Robert J. Therrien agreed to vote all his shares in favor of such
nominees for election to the board of directors. These voting obligations of
Brooks and Mr. Therrien expired in fiscal 2001 when Jenoptik sold some of its
shares of Brooks common stock. Jenoptik agreed to cause M+W to vote in favor of
the other candidates to Brooks' board of directors nominated by Brooks' existing
board. Jenoptik also agreed to cause M+W to vote for other matters in accordance
with the recommendation of a majority of the Brooks board. Jenoptik agreed not
to buy or sell shares of the common stock except in specified circumstances.
Jenoptik further agreed to share certain information with Brooks regarding
upcoming factory automation projects, to give Brooks a right of first refusal as
a supplier and to award Brooks an exclusive supply contract with guaranteed,
minimum gross margin of at least $15 million in connection with an upcoming
project.

                                        12



Jenoptik and Brooks also entered into a one year transitional services
agreement, pursuant to which Jenoptik agreed to allow Brooks to occupy space at
its Jena, Germany manufacturing facility and to receive support services from
Jenoptik. Brooks agreed to reimburse Jenoptik for the provision of space and
support services at cost. This transitional services agreement was extended
through December 2002.



     On October 16, 2000, the parties amended the agreement to permit the
removal of the transfer restrictions with respect to an aggregate of 868,572
shares of Brooks common stock held by Jenoptik, and the grant by Brooks of
certain registration rights under the Securities Act of 1933, as amended, with
respect to such shares. In consideration for a payment of $5.1 million, Brooks
released certain claims for indemnification against Jenoptik and agreed as soon
as commercially reasonable after January 15, 2001 to register 434,286 shares of
Brooks common stock held by Jenoptik. Brooks has further agreed to register an
additional 434,286 shares as soon as commercially reasonable after October 15,
2002. The amendment released Jenoptik from the requirement to award Brooks the
exclusive contract with guaranteed gross margins and Jenoptik released its
claims to the 5% holdback.



DAIFUKU STOCKHOLDER AGREEMENT



     On January 6, 2000, Brooks completed the acquisition of Auto-Soft
Corporation and AutoSimulations, Inc. from their sole stockholder, Daifuku
America Corporation, the U.S. affiliate of Daifuku Co., Ltd., for $27 million in
cash, 535,404 shares of Brooks common stock and issuance of a note in the amount
of $16 million which was repaid on January 5, 2001. The note was unsecured and
bore interest at 4% per year. As part of the transaction, Daifuku America
Corporation and Daifuku Co., Ltd. entered into a stockholder agreement with
Brooks under which they agreed to take such action as may be required so that
all voting securities of Brooks owned by them and their affiliates (i) are
represented at all meetings and (ii) are voted in accordance with the
recommendation of Brooks' board of directors. The stockholder agreement also
restricted Daifuku from buying or selling shares of Brooks common stock except
in specified circumstances. A separate registration rights agreement granted
Daifuku certain registration rights for the stock it received in the
transaction. The parties also entered into a series of technology
cross-licensing arrangements related to the technology of the two acquired
companies and Daifuku which, in some cases, provide most favored customer terms.
Daifuku America Corporation has sold all its shares of Brooks common stock.
