Item 2.    ACQUISITION

On September 30, 1999, the Registrant acquired substantially all of the assets
and assumed certain of the liabilities of the Infab Division of Jenoptik AG
("Jenoptik") in exchange for 914,286 shares of the Registrant's common stock,
subject to adjustment pending the completion of a post closing review of the
purchased assets. The Infab Division is a worldwide supplier of advanced factory
automation systems headquartered in Germany. The assets purchased from the Infab
Division included fixed assets, usable inventory, collectible receivables,
patents and intellectual property. The Registrant intends to continue to use
these assets in connection with its conduct of the business of the former Infab
Division.

As part of this transaction, the Registrant appointed Jurgen Giessmann, an
executive officer of Jenoptik, to the Registrant's Board of Directors pursuant
to a Stockholder Agreement dated September 30, 1999 among the Registrant,
Jenoptik, a subsidiary of Jenoptik and Robert J. Therrien, the president and
chief executive officer of the Registrant and a member of the Registrant's Board
of Directors. Under the Stockholder Agreement, until Jenoptik no longer holds
all its shares purchased from the Registrant in this transaction, or until
September 30, 2004, whichever occurs first, the Registrant has agreed to
nominate a reasonably acceptable candidate of Jenoptik to the Registrant's Board
of Directors in each election of the Registrant's directors, Robert J. Therrien
agreed to vote all his shares in favor of such nominees for election to the
Board of Directors. Jenoptik, in turn, agreed to vote in favor of the other
candidates to the Registrant's Board of Directors and for other matters, in the
same proportion as the votes cast by the other holders of the Registrant's
common stock. Jenoptik also agreed not to buy or sell shares of the Registrant's
common stock except in specified circumstances. Jenoptik further agreed to share
information with the Registrant regarding upcoming projects and to give the
Registrant the right of first refusal as a supplier. The terms of the asset
purchase are more fully described in the Stockholder Agreement and the Master
Purchase Agreement dated as of September 30, 1999, among the Registrant,
Jenoptik and certain of their respective direct or indirect subsidiaries.

Except as otherwise summarized in this Report, there is no material relationship
between Jenoptik and the Registrant or any affiliate, director or officer of the
Registrant or any associate of any such director or officer. The terms of this
transaction and the consideration received by Jenoptik were as a result of
arms-length negotiations between representatives of Jenoptik and the Registrant.

Item 7.    FINANCIAL STATEMENTS AND EXHIBITS

           (a)    FINANCIAL STATEMENTS OF BUSINESS ACQUIRED

after the Closing at the request of Buyer and without further consideration
shall execute and deliver further instruments of transfer and assignment (in
addition to those delivered under Section 2.5(b) and (c)) and take such other
action as Buyer may reasonably require to more effectively transfer and assign
to, and vest in, Buyer each of the Purchased Assets. To the extent that the
assignment of any lease, contract, commitment or right shall require the consent
of other parties thereto, this Agreement shall not constitute an assignment
thereof; however, each of the Sellers shall use its reasonable best efforts
before and after the Closing to obtain any necessary consents or waivers to
assure Buyer of the benefits of such leases, contracts, commitments or rights.
If such consent is not obtained, Sellers agree to cooperate with Buyer in any
reasonable arrangement designed to provide for Buyer the benefits thereunder,
including, but not limited to, having (a) Buyer act as agent for Sellers and (b)
Sellers enforce for the benefit of Buyer any and all rights of Sellers against

otherwise. Each of the Sellers shall cooperate with Buyer to permit Buyer to
enjoy each of the Sellers' rating and benefits under the workman's compensation
laws and unemployment compensation laws of applicable jurisdictions, to the
extent permitted by such laws. Nothing herein shall be deemed a waiver by Buyer
of its right to receive at the Closing an effective assignment of each of the
leases, contracts, commitments or rights of Sellers.

                           (c) Each of the Infab Companies from time to time

shall execute and deliver further instruments of transfer and assignment (in
addition to those delivered under Section 2.6(b)) and take such other action as
Buyer may reasonably require to more effectively transfer and assign to, and
vest in, Buyer the Infab Shares.

                           (d) Buyer from time to time after the Closing at the
request of M+W and without further consideration shall execute and deliver

Sellers the Purchase Shares.

         ARTICLE III. AGGREGATE CONSIDERATION

                  3.1. AGGREGATE CONSIDERATION AND PAYMENT.

                           (a) Subject to the adjustment in Section 3.2, the
aggregate consideration to be paid by the Buyer to M+W (the "Aggregate
Consideration") in consideration of the sale of the Infab Business, the
Purchased Assets and the Infab Shares shall be equal to:

                                    (i) the aggregate amount of the Assumed
Liabilities as of the Closing; plus

                                    (ii) that number of the shares of Buyer
Common Stock which represents an aggregate value equal to $24,400,000 at the
Formula Price (the "Purchase Shares").

                           (b) The Aggregate Consideration shall be paid by
Buyer as follows:

                                    (i) that number of shares of Buyer Common
Stock which represents an aggregate value equal to $23,180,000 at the Formula
Price shall be paid to M+W at the Closing; and

                                    (ii) the balance of the Purchase Shares (the
"Holdback") shall be reserved for issuance pending adjustment in accordance with
Section 3.2 hereof.

                  3.2. DETERMINATION OF CLOSING NET BOOK VALUE; ADJUSTMENT OF
THE AGGREGATE CONSIDERATION.

                           (a) Not later than thirty (30) days after the Closing
Date, Sellers shall prepare and deliver to the Buyer (i) a balance sheet (the
"Closing Balance Sheet") which shall reflect the book value of both the
Purchased Assets and the Assumed Liabilities as of the Closing Date and (ii) a
statement (the "Closing Statement") indicating the difference between the
aggregate net book value of the Purchased Assets and the aggregate net book
value of the Assumed Liabilities (the "Closing Net Book Value"). The Closing
Balance Sheet shall be prepared in accordance with German GAAP. The Closing
Balance Sheet delivered to Buyer shall be accompanied by a certificate from KPMG
Peat Marwick, the accountants of the Sellers, that the Closing Balance Sheet has
been prepared in accordance with German GAAP. The Closing Balance Sheet shall
also be accompanied by all necessary and appropriate supporting work papers and
materials. If these work papers and materials have not been provided or

prepared in a professional and workmanlike manner, the Review Period referenced
in Section 3.2(b) hereof shall be extended to give Buyer's accountants
sufficient time to complete their audit of the Closing Balance Sheet. Inventory
shall be valued as provided in Section 5.11 hereof by Buyer as of the close of
business on the Closing Date based on a physical count undertaken on a mutually
agreed upon date that is on or near the Closing Date at which all parties or
their representatives may be present to observe. To the extent that the Closing
Net Book Value differs from the comparable net book value as derived from the
Base Asset Allocation listed on SCHEDULE 2.1(b) hereof (the "Base Net Book
Value"), then the Aggregate Consideration shall be adjusted up or down on a
dollar for dollar basis by the amount of such difference as hereinafter set
forth. The Base Net Book Value equals $24,400,000.

                           (b) Following receipt of the Closing Balance Sheet,
Buyer and Buyer's accountants will be afforded a period of 120 calendar days
(the "Review Period") to audit, at Buyer's cost, the Closing Balance Sheet.
During such Review Period, Buyer and Buyer's accountant will be afforded
reasonable access to any of Sellers' employees involved in the preparation of
the Closing Balance Sheet and the records, work papers, trial balances and
similar materials prepared by Sellers or their accountants in connection with
the preparation of the audit and certification of the Closing Balance Sheet;
provided, however, that Buyer shall provide reasonable prior notice of any such
investigation to Sellers so as not to unduly interfere with the operations of
Sellers. At or before the end of the Review Period, Buyer will either (i) accept
the Closing Balance Sheet and the Closing Statement in their entirety, in which
case the Closing Net Book Value will be deemed to be as set forth on the Closing
Statement, and the Closing Balance Sheet and the Closing Statement shall become
final, binding and conclusive on Sellers and Buyer, or (ii) deliver to Sellers
and Sellers' accountants a written notice in accordance with paragraph (d) of
this Section 3.2 disputing the Closing Balance Sheet or the Closing Statement.

                           (c) Within ten (10) days following the later of (x)
the date the Closing Balance Sheet and the Closing Statement is accepted by
Buyer or (y) the final, binding and conclusive determination of any dispute with
respect to the Closing Balance Sheet or the Closing Statement as provided in
paragraph (d) of this Section 3.2:

                                    (i) if the Closing Net Book Value is less
than the Base Net Book Value and such difference is less than or equal to the
Holdback, then Buyer shall pay to M+W an amount of Buyer Common Stock, based
upon the Formula Price, equal to (i) the Holdback minus (ii) such difference;

                                    (ii) if the Closing Net Book Value is less
than the Base Net Book Value and such difference is greater than the Holdback,
then M+W shall pay to Buyer an amount of Buyer Common Stock, based upon the
Formula Price, equal to (i) the Base Net Book Value minus (ii) the Closing Book
Value minus (iii) the Holdback;

                                    (iii) if the Closing Net Book Value is
greater than the Base Net Book Value, then Buyer shall pay to M+W an amount of
Buyer Common Stock, based upon the Formula Price, equal to the sum of (i) the
Holdback plus (ii) such difference; and

                                    (iv) if the Closing Net Book Value and the
Base Net Book Value are equal, then the Buyer shall pay to M+W an amount of
Buyer Common Stock, based upon the Formula Price, equal to the Holdback.

                           (d) In the event that any dispute shall arise as to
the manner of preparation or the accuracy of the Closing Balance Sheet or
Closing Statement prior to the expiration of the Review Period, the Buyer shall
provide Sellers with written notice of each disputed item. In the event of such
a dispute, Buyer and Sellers shall attempt to reconcile in good faith their
differences as to such items within twenty (20) calendar days (the "Resolution
Period") of Sellers' receipt of such notice, and any resolution by them as to
any disputed items shall be final, binding and conclusive on Sellers and Buyer.
If Buyer and Sellers are unable to reach a resolution with such effect within
the Resolution Period, Buyer and Sellers shall submit the dispute to the
Independent CPA. The determination of such dispute by the Independent CPA shall
be final, binding and conclusive on the parties. The fees and expenses of the
Independent CPA shall be assessed by the Independent CPA fifty percent (50%)
against the Sellers and fifty percent (50%) against the Buyer, and shall be paid
by each of them in those proportions.

                  3.3. ALLOCATION OF AGGREGATE CONSIDERATION. The Aggregate
Consideration shall be allocated among the Purchased Assets and the Infab Shares
in the manner set forth in SCHEDULE 3.3 annexed hereto, subject to any
adjustment to the Aggregate Consideration which shall be made pursuant to
Section 3.2 hereof. The parties hereto acknowledge and agree that such
allocation reflects the respective fair market values of the Purchased Assets
and the Infab Shares and that they will not take a position inconsistent with
such allocation for federal, state, provincial or local Tax purposes. SCHEDULE
3.3 also apportions the Purchased Assets and Infab Shares among the Buyer
Entities.

be held indefinitely unless they are subsequently registered under the

                  5.8. PAYMENT OF TAXES.

                           (a) The Companies have paid or made appropriate
reserves in the financial statements in Section 5.7 above for all Taxes due
related to the Infab Business. With respect to all Taxes or which have not yet
accrued or otherwise become due, to the Companies' knowledge, adequate provision
has been made in the pertinent financial statements referred to in Section 5.7
above. The provisions for Taxes reflected in the above-mentioned financial
statements are adequate to cover any liabilities of any of the Companies for
Taxes in respect of the operation of the Infab Business during the periods
covered by said financial statements and all prior periods. All Taxes and other
assessments and levies which any of the Companies is required to withhold or
collect on behalf of any Governmental Authority with respect to the Infab

the proper Governmental Authorities as required.

                           (b) Each of Infab (Ireland) and Infab (Scotland) has

(Ireland) and Infab (Scotland) for the most recent two (2) fiscal years are
attached to SCHEDULE 5.8. All Taxes shown to be due on the Tax Returns have been

SCHEDULE 5.8.

                           (c) Except as set forth on SCHEDULE 5.8, none of the
Tax Returns have been examined, reviewed or audited by any Governmental
Authority, nor are any of the Companies aware of any intention on the part of
any Governmental Authority to do so. No Governmental Authority in any relevant
jurisdiction is now asserting or, to the knowledge of any of the Companies,
threatening to assert, against Infab (Ireland) or Infab (Scotland) any claim for
additional Taxes, or interest thereon or penalties in connection therewith with
respect to the Infab Business or any other activities which may create any Lien
upon Infab (Ireland) or Infab (Scotland). None of Infab (Ireland) or Infab
(Scotland) has extended the time for the filing of any Tax Return or waived any
statute of limitations for the assertion of liability by any Governmental
Authority for any tax year, which extension or waiver is still in effect.

terms and conditions of each lease of Material Real Property or Material
Personal Property and no event has occurred nor, to the Companies' knowledge,
does any circumstance exist that (with or without notice or the passage of time
or both) would constitute a material violation or default under any such lease
and none of the Companies has given or received notice of any alleged violation
or of any default under any such agreement.

                           (e) Each of the Companies has good and marketable
title in fee simple to all of its owned personal property included in the
Purchased Assets. None of the Material Real Property or Material Personal
Property owned or used by each of the Companies is subject to any Lien (other
than for taxes not yet due and payable) of any kind against any such Company's
rights in such property and, to the extent such property is used by the Company
but owned by a third party, to the knowledge of the Companies there are no Liens
(other than for taxes not yet due and payable) of any kind against such third
party's rights in such property.

                           (f) All buildings, machinery and equipment used or
owned by any of the Companies in the operation of the Infab Business are in
satisfactory condition, presently working order and repair, normal wear and tear

Licensed Products were less than $300,000 for the twelve months ended August 31,
1999. Revenues of the Infab Business attributable to such Licensed Products are
expected to be less than $300,000 for the twelve months ended August 31, 2000
based upon backlog and business trends in the Infab Business to date. If the
Infab Business were to lose its rights to such Licensed Products, the only
adverse effect to the Infab Business would be the loss of revenue directly
attributable to such Licensed Products, which would not exceed $300,000 in the
next twelve months.

                           (g) No proceedings to which any Company is a party
are pending which (i) challenge the rights of any Company in respect of the
Intellectual Property required to be listed on SCHEDULE 5.12(b)(2), or (ii)
charge any Company with infringement of any other person's rights in
Intellectual Property. To the knowledge of each Company, no such proceeding to
which a Company is not a party has been filed or is threatened to be filed.

                           (h) None of the Companies is infringing upon any
valid Statutory Intellectual Property rights of any other person and, to the
knowledge of any of the Companies, none of the rights in Statutory Intellectual
Property required to be listed on SCHEDULE 5.12(b)(2) is being infringed by any
other person. None of the Companies is using or in any way making use of any
Trade Secrets of any third party, including without limitation a former employer
of any employee of a Company and, to the knowledge of any of the Companies, no
other person is using any Trade Secret of any Company without authorization.

                           (i) Neither Jenoptik nor M+W, nor any Company officer
or employee owns, directly or indirectly, in whole or in part, any Intellectual
Property right which any

                  7.4. ASSIGNMENT OF CONTRACTS. To the extent that the sale of
the Infab Shares or the Purchased Assets constitutes an assignment under the
terms of any contract to which any of the Companies is a party (including leases
for real property) or any Governmental Authorization which requires the consent
of another party, each Infab Company agrees to use its best efforts (with the
reasonable assistance of the Buyer to the extent necessary to obtain such
consents) to obtain the consent of such other party to an assignment in all
cases in which consent is required.

                  7.5. MAINTENANCE OF GOVERNMENT AUTHORIZATIONS. Each Infab

to preserve and maintain each of the Government Authorizations free and clear of
all Liens. Jenoptik, M+W and M+W (US) shall not take any action or permit any of
the Companies to take any action which would cause any Governmental Authority to
institute proceedings regarding any of the Government Authorizations or take any
other action which would result in any of the Companies being in noncompliance
in any material respect with the requirements of any Governmental Authority
having jurisdiction thereof.

                  7.6. COLLECTION OF RECEIVABLES.

                  Between the date hereof and the Closing Date, each of the

collect the Receivables so as not to jeopardize Buyer's future customer
relations.

                  7.7. RISK OF LOSS. Legal title and risk of loss with respect
to the Purchased Assets and the Infab Business shall not pass to Buyer until the
Closing. Prior to the Closing Date, if any of the assets of any of the
Companies, including the Purchased Assets, are destroyed or damaged by fire or
other casualty, Buyer may, at its option, if the amount of such destruction or
damage is in excess of $3,000,000, terminate this Agreement. In the event that
Buyer elects not to terminate this Agreement, the amount of any insurance
proceeds shall not be taken into account in connection with the determination of
any adjustment to the purchase price.

                           (a) Jenoptik, M+W and M+W (US) agree to cause the

                                    (ii) resulting from or arising out of any

Agreement or any Purchase Agreement;

                                    (iii) resulting from or arising out of

                  11.3. DEFENSE OF THIRD PARTY ACTIONS.

                           (a) Promptly after receipt of notice of any Third
Party Action, any person who believes he, she or it may be an Indemnified Person
will give notice to the potential Indemnifying Person of such action. The
omission to give such notice to the Indemnifying Person will not relieve the
Indemnifying Person of any liability hereunder unless it was prejudiced thereby,
nor will it relieve it of any liability which it may have other than under this
Article.

                           (b) Upon receipt of a notice of a Third Party Action,
the Indemnifying Person shall have the right, at its option and at its own
expense, to participate in and be present at the defense of such Third Party
Action, but not to control the defense, negotiation or settlement thereof, which
control shall remain with the Indemnified Person, unless the Indemnifying Person
makes the election provided in paragraph (c) below.

                           (c) By written notice within forty-five (45) days
after receipt of a notice of a Third Party Action, an Indemnifying Person may
elect to assume control of the defense, negotiation and settlement thereof, with
counsel reasonably satisfactory to the Indemnified Person; provided, however,
that the Indemnifying Person agrees (i) to promptly indemnify the Indemnified
Person for its expenses to date, and (ii) to hold the Indemnified Person
harmless from and against any and all Losses caused by or arising out of any
settlement of the Third Party Action approved by the Indemnifying Person or any
judgment in connection with that Third Party Action. The Indemnifying Persons
shall not in the defense of the Third Party Action enter into any settlement
which does not include as a term thereof the giving by the third party claimant
of an unconditional release of the Indemnified Person, or consent to entry of
any judgment except with the consent of the Indemnified Person.

                           (d) Upon assumption of control of the defense of a
Third Party Action under paragraph (c) above, the Indemnifying Person will not
be liable to the Indemnified Person hereunder for any legal or other expenses
subsequently incurred in connection with the defense of the Third Party Action,
other than reasonable expenses of investigation.

                           (e) If the Indemnifying Person does not elect to
control the defense of a Third Party Action under paragraph (c), the
Indemnifying Person shall promptly reimburse the Indemnified Person for expenses
incurred by the Indemnified Person in connection with defense of such Third
Party Action, as and when the same shall be incurred by the Indemnified Person.

                           (f) Any person who had the right hereunder but did
not assumed control of the defense of any Third Party Action shall have the duty
to cooperate with the party which assumed such defense.

                  11.4. MISCELLANEOUS.

                           (a) Buyer's Indemnified Persons shall be entitled to
indemnification under Section 11.1(a) and Sellers' Indemnified Persons shall be
entitled to indemnification under Section 11.2(a), regardless of whether the
matter giving rise to the applicable liability, payment, obligation or expense
may have been previously disclosed to any such person, unless expressly assumed
on the particular Schedule.

                           (b) If any Loss is recoverable under more than one
provision hereof, the Indemnified Person shall be entitled to assert a claim for
such Loss until the expiration of the longest period of time within which to
assert a claim for Loss under any of the provisions which are applicable.

                           (c) Buyer may, at its options, recover any amount
owing by Jenoptik for indemnification hereunder by setoff against any amounts
that may otherwise be due from the Buyer to Jenoptik, M+W, M+W(US) or the
Sellers, or any of them, whether hereunder or otherwise; provided that Buyer
shall not be required to recover such claims in such manner and may proceed
against the Indemnified Party at any time or times for recovery of
indemnification claims.

                  11.5. PAYMENT OF INDEMNIFICATION. Claims for indemnification
under this Article shall be paid or otherwise satisfied by Indemnifying Persons

shall not have been cured within 30 days after notice thereof has been given by

divulge any confidential, proprietary or secret information which they may
obtain from any of the other in connection with the transactions contemplated
herein, or pursuant to inspection rights granted hereunder, or reveal the
financial or other terms and conditions of this Agreement unless such
information is or hereafter becomes public information through means other than
a default hereof by such party or is required to be disclosed by applicable law,
including applicable securities laws or stock exchange rules or regulations. The
obligations of this Section 13.5 shall survive any termination of this
Agreement.

                  13.6. TIME PERIOD. The parties acknowledge that time is of the
essence with respect to the fulfillment of the respective obligations of the
parties hereto and the Closing of the Transaction as contemplated by this
Agreement.

                  13.7. ENTIRE AGREEMENT. This Agreement together with the other
Purchase Agreements and the Ancillary Documents (including all exhibits or
schedules appended to this Agreement and all documents delivered pursuant to or
referred to in this Agreement, all of which are hereby incorporated herein by
reference) constitutes the entire agreement between the parties, and all
promises, representations, understandings, warranties and agreements with
reference to the subject matter hereof and inducements to the making of this
Agreement relied upon by any party hereto, have been expressed herein or in the
documents incorporated herein by reference.

                  13.8. SEVERABILITY. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provision hereof.

                  13.9. ASSIGNABILITY. This Agreement may not be assigned
otherwise than by operation of law (a) by Buyer without the prior written
consent of M+W or (b) by Jenoptik or any Infab Company without the prior written
consent of Buyer. However, any or all rights of Buyer to receive performance
(but not the obligations of Buyer hereunder) and rights to assert claims against
Jenoptik, M+W or M+W(US) in respect of breaches of representations, warranties
or covenants of Jenoptik or any Infab Company hereunder, may be assigned by
Buyer to any direct or indirect subsidiary, parent or other affiliate of Buyer,
but any assignee of such rights shall take such rights subject to any defenses,
counterclaims and rights of setoff to which any member of the Infab Group might
be entitled under this Agreement. This Agreement shall inure to the benefit of
and be binding upon the parties hereto and their respective successors and
permitted assigns.

                  13.10. AMENDMENT. This Agreement may be amended only by a
written agreement executed by Buyer and M+W, for Jenoptik and each of the Infab
Companies.

                  13.11. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the Commonwealth of Massachusetts
(other than the choice of law principles thereof), except that any
representations and warranties with respect to real and tangible property shall
be governed by and construed in accordance with the laws of the jurisdiction
where such property is situated if other than in the Commonwealth of
Massachusetts.

                  13.12. REMEDIES. The parties hereto acknowledge that the
remedy at law for any breach of the obligations undertaken by the parties hereto
is and will be insufficient and

inadequate and that the parties hereto shall be entitled to equitable relief, in
addition to remedies at law. In the event of any action to enforce the
provisions of this Agreement, the parties shall waive the defense that there is
an adequate remedy at law. Infab (Germany) acknowledges that the Infab Shares
are unique and cannot be obtained on the open market. Without limiting any
remedies any party may otherwise have hereunder or under applicable law, in the
event any other party refuses to perform its obligations under this Agreement,
the first party shall have, in addition to any other rights at law or equity,
the right to specific performance.

                  13.13. COUNTERPARTS. This Agreement may be executed in
multiple counterparts, each of which shall be deemed an original but all of
which together shall constitute one and the same instrument.

                  13.14. EFFECT OF TABLE OF CONTENTS AND HEADINGS. Any table of
contents, title of an article or section heading herein contained is for
convenience of reference only and shall not affect the meaning of construction
of any of the provisions hereof.

                  13.15. DISPOSITION OF PURCHASE SHARES. Jenoptik and the Infab
Companies agree that they will not sell or otherwise dispose of any of the
Purchase Shares in violation of the registration requirements of the Securities
Act of 1933 or in violation of any other federal or state laws or regulations
governing the sale or other disposition of securities.

            IN WITNESS WHEREOF the parties hereto have caused this Agreement to
be executed as an instrument under seal in multiple counterparts as of the date
set forth above by their duly authorized representatives.

                              STOCKHOLDER AGREEMENT

         STOCKHOLDER AGREEMENT entered into as of the 30th day of September,
1999, by and among Brooks Automation, Inc., a Delaware corporation with its
principal place of business at 15 Elizabeth Drive, Chelmsford, Massachusetts
01824 (the "Company"), Robert J. Therrien in his capacity as a stockholder of
the Company ("Therrien"), Meissner + Wurst Zander Holding GmbH, a German
corporation with offices at Stuttgart, Germany ("Investor") and Jenoptik AG, a
German corporation and the parent corporation of the Investor ("Jenoptik").

                              W I T N E S S E T H:
                              - - - - - - - - - -

         WHEREAS, the Company, the Investor, Jenoptik, Jenoptik Infab GMBH,
Jenoptik Infab KK, Jenoptik Infab, Inc., Jenoptik Infab PLC ("Infab Ireland")
and Jenoptik Infab, Ltd. ("Infab Scotland"), direct or indirect subsidiaries of
the Investor, have on this date entered into a Master Purchase Agreement (the
"Master Purchase Agreement") whereby the Company has agreed to purchase all the
issued and outstanding common stock of Infab Scotland and Infab Ireland
(collectively, the "Infab Shares") and the Purchased Assets (as defined in the
Master Purchase Agreement) in exchange for shares of Common Stock of the Company
(the "Purchase Shares");

         WHEREAS, it is a condition to the Master Purchase Agreement that this
Stockholder Agreement be entered into; and

         WHEREAS, the Investor and the Company wish to enter into certain
agreements relating to the terms upon which the Purchase Shares shall be held
and transferred and other matters;

         NOW, THEREFORE, in consideration of the Master Purchase Agreement and
other good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, and intending to be legally bound, it is hereby agreed by
and between the parties as follows:

ARTICLE 1. COVENANTS OF THE COMPANY AND THERRIEN

         The Company agrees with the Investor that following the Closing:

         1.1 BOARD APPOINTMENT. The Company effective immediately upon the
Closing appoints Jurgen Giessman to serve on the Company's Board of Directors
until the Company's next annual meeting of stockholders.

         1.2 AGREEMENT TO VOTE. Until such time as the Investor and its
Affiliates no longer hold all of the Purchase Shares (after giving effect to the
post closing adjustments provided for in the Master Purchase Agreement) or until
five years from the date of this Agreement, whichever first occurs:

                  (a) In each election of directors (whether at special or
annual meeting or by written consent), the Board of Directors of the Company
will nominate as one of the nominees of the Board of Directors for election as a
director the person designated by the Investor as set forth in paragraph (b).
Therrien shall vote all shares of the Company's Common Stock controlled by him,
directly or indirectly, in favor of the election of such person to the Company's
Board of Directors.

         Execution Copy                 1


<PAGE>   4


                  (b) The Investor shall designate one person as its nominee to
be a director of the Company, which person shall be Mr. Jurgen Geissman or such
other person as may be designated by the Investor and (i) is acceptable to
Therrien and the other members of the Board of Directors of the Company in their
reasonable discretion and (ii) shall not be a Competitor. The nominee so
selected by the Investor shall be specified in a written notice delivered to
Therrien and the Board of Directors a reasonable period of time prior to
completion by the Company of its proxy materials. Therrien and the Board of
Directors shall indicate his and its approval or disapproval, as the case may
be, promptly after receipt of the written notice.

                  (c) Investor shall take such action as may be required so that
all Voting Securities owned by the Investor or any of the Affiliates are voted
for nominees to the Board of Directors of the Company and, unless the Company
otherwise consents in writing, on all other matters to be voted on by the
holders of Voting Securities, in the same proportion as the votes cast by other
holders of Voting Securities; PROVIDED that Voting Securities owned by the
Investor or any Affiliate may be voted as such persons determine in their sole
discretion on any Significant Event. The Investor and its Affiliates, as holders
of Voting Securities, shall be present, in person or by proxy, at all meetings
of shareholders of the Company so that all Voting Securities beneficially owned
by them may be counted for the purpose of determining the presence of a quorum
at such meetings.

                  (d) Each director selected and elected in accordance with
Sections 1.1 and 1.2 shall serve until his successor is designated, elected and
qualified or until his earlier resignation or removal. The designee of the
Investor may be removed during his term of office without cause only by vote of
the stockholders. Any vacancy in the office of the director selected by the
Investor shall be filled by the parties promptly in accordance with paragraph
(b) above, and his office shall not be filled by the directors other than by a
person designated by Investor.

ARTICLE 2. COVENANTS OF INVESTOR.

The Investor agrees with the Company that following the Closing:

         2.1 STANDSTILL AGREEMENT. Neither Investor nor any Affiliate of the
Investor will without the prior written consent of the Company, directly or
indirectly, acquire any Voting Securities (except by way of stock dividends or
other distributions or offerings made available to holders of Voting Securities
generally) if the effect of such acquisition would be to increase the aggregate
voting power in the election of directors of all Voting Securities then owned by
Investor and all its Affiliates to greater than the combined voting power of all
the Purchase Shares (after giving effect to the post closing adjustments in
connection with the Master Purchase Agreement); PROVIDED THAT:

                  (a) The Investor may acquire Voting Securities without regard
to the foregoing limitation if any of the following events (each a "Triggering
Event") shall occur: (i) a tender or exchange offer is made by any person or
Schedule 13D Group to acquire Voting Securities which, if added to any Voting
Securities (if any) already owned by such person or Schedule 13D Group, would
represent more than 25% of the total combined voting power of all Voting


- --------------------------------------------------------------------------------
         Stockholder Agreement
         Execution Copy                 2


<PAGE>   5


Securities then outstanding; (ii) it is publicly disclosed or Investor otherwise
learns that Voting Securities representing more than 25% of the total combined
voting power of all Voting Securities then outstanding have been acquired
subsequent to September 30, 1999, or are proposed (in a public announcement or
filing) to be acquired subsequent to such date by any person or Schedule 13D
Group; or (iii) any person or Schedule 13D Group shall beneficially own Voting
Securities representing more than 25% of the total combined voting power of all
Voting Securities than outstanding, and would be required (under rules and
regulations in effect on the date hereof) to file a statement on Schedule 13D
with the SEC reporting beneficial ownership of such Voting Securities.

                  (b) neither the Investor nor any Affiliate of the Investor
shall be obligated to dispose of any Voting Securities if the aggregate
percentage ownership of the Investor and its Affiliates is increased as a result
of a recapitalization of the Company, a repurchase by the Company of its Voting
Securities or any other action taken by the Company or its affiliates other than
the Investor and its Affiliates.

         2.2 PROXY SOLICITATIONS.

                  (a) Neither the Investor nor any Affiliate of the Investor
shall solicit proxies or become a "participant" in a "solicitation" (as such
terms are defined in Regulation 14A under the Exchange Act) in opposition to the
recommendation of the majority of the directors of the Company with respect to
any matter; PROVIDED THAT (i) if the Investor opposes any solicitation by the
Company's management with respect to any Significant Event, the Company shall
include in its proxy statement in connection with such solicitation the fact
that Investor opposes such solicitation and a brief statement provided by
Investor stating Investor's reasons for such opposition and (ii) if at any time
a designee of the Investor is serving as a member of the Company's Board of
Directors, the Investor shall not be deemed to be a "participant" solely by
reason of the membership of such designee on the Board of Directors of the
Company.

                  (b) Except in the case of a Triggering Event, neither the
Investor nor any Affiliate of the Investor shall join a partnership, limited
partnership, syndicate or other group, or otherwise act in concert with any
other person, for the purpose of acquiring, holding, voting or disposing of
Voting Securities, or otherwise become a "person" within the meaning of Section
13(d)(3) of the Exchange Act (in each case other than solely with the Investor
and its Affiliates). In the case of a Triggering Event, subject to the
limitations in this Section 2.2(b), Investor may join a partnership, limited
partnership, syndicate or other group, or otherwise act in concert with any
other person, for the purpose of acquiring, holding, voting or disposing of
Voting Securities or otherwise become a "person" within the meaning of Section
13(d)(3) of the Exchange Act. In no case shall Investor or any of its Affiliates
be permitted to join a partnership, limited partnership, syndicate or other
group with any person or Schedule 13D Group participating in the Triggering
Event or otherwise act in concert with any person or become a "person" within
the meaning of Section 13(d)(3) of the Exchange Act in either case in connection
with any person or Schedule 13D Group participating in the Triggering Event.

         2.3 VOTING AGREEMENTS. Neither the Investor nor any Affiliate of the
Investor shall deposit any Voting Securities in a voting trust or subject any
Voting Securities to any arrangement or agreement with respect to the voting of
such Voting Securities.

ARTICLE 3. RESTRICTION ON TRANSFERS.

         3.1 RESTRICTION ON TRANSFERS. Until five years after the date of this
Agreement, Investor may not transfer any interest in any Voting Securities
directly or indirectly owned by it (whether by way of gift, sale, transfer,
assignment, pledge, hypothecation, mortgage or otherwise). After five years from
the date of this Agreement, Investor may transfer any interest in any Voting
Securities directly or indirectly owned by it (whether by way of gift, sale,
transfer, assignment, pledge, hypothecation, mortgage or otherwise) provided (i)
such transfer is not to a Competitor and (ii) Investor shall have first offered
the Company a right of first refusal in the manner provided in this Article 3.
These restriction on transfer shall not apply to any offer or transfer of Voting
Securities: (a) to the Investor or one of its other Affiliates, provided that
any such transferee shall comply with Section 3.3, (b) to the Company or any
person or group approved in writing by the Company, (c) in response to (i) an
offer to purchase or exchange for cash or other consideration any Voting
Securities (A) which is made by or on behalf of the Company or (B) which is made

Exchange Act to advise the shareholders of the Company of the Board's position
on such offer, or (d) pursuant to a plan of liquidation of the Company.

         3.2 EXCEPTIONS. The first refusal right of this Article shall not apply
to any offer or transfer (a) to the Investor or one of its other Affiliates,
provided that any such transferee shall comply with Section 3.3, (b) after five
years from the date of this Agreement, pursuant to a rights offering or a
dividend or other distribution to stockholders of the Investor or any of its
Affiliates, (c) after five years from the date of this Agreement, unsolicited
brokerage transactions of less than the amount that would be permitted by Rule
144(e) under the Securities Act if it were applicable, (d) as a result of any
pledge or hypothecation to a bona fide financial institution to secure a bona
fide loan or the foreclosure of any lien or encumbrance which may be placed upon
any Voting Securities (whether voluntarily or involuntarily), (e) to the Company
or any person or group approved in writing by the Company, (f) in response to
(i) an offer to purchase or exchange for cash or other consideration any Voting
Securities (A) which is made by or on behalf of the Company or (B) which is made
by another person or group and is approved by the Board of Directors of the
Company within the time such Board is required pursuant to regulations under the
Exchange Act to advise the shareholders of the Company of the Board's position
on such offer or (g) pursuant to a plan of liquidation of the Company.

         3.3 AGREEMENT BY TRANSFEREE. No person shall receive an interest
pursuant to Section 3.2(a) in any Voting Securities now or hereafter held by the
Investor, whether such receipt was voluntary, involuntary or by operation of
law, unless such person shall first agree in writing to be bound by all of the
terms of this Agreement as if such transferee were the Investor hereunder.

         3.4 CERTIFICATES LEGENDED. Upon the execution of this Agreement, and
during the term of this Agreement, each certificate evidencing any of the Shares
held by Investor or any Affiliate shall be conspicuously legended as follows:

                  The stock evidenced by this certificate is subject to the
                  restrictions of, and is transferable only upon compliance with
                  the provisions of, a Stockholder Agreement dated September 30,
                  1999 between the corporation and the holders of certain
                  securities of the corporation. A copy of said agreement is on
                  file in

         Execution Copy                 4

                  the office of the corporation, and a copy thereof will be
                  mailed to the holder hereof without charge upon receipt of a
                  written request therefor.

         3.5 SALES TO THIRD PARTIES.

                  (a) Subject to Sections 3.1 and 3.2 hereof, if at any time
during the term of this Agreement the Investor proposes to transfer any Voting
Securities now or hereafter directly or indirectly beneficially owned by it
("Selling Stockholder") to a Proposed Transferee, it shall first submit a
written offer (the "First Refusal Offer") to sell such shares (the "Offered
Shares") to the Company as provided in this Article 3.

                  (b) The First Refusal Offer shall disclose the identity of
and, if available, information about the Proposed Transferee and the terms of
the Proposed Transfer, the number of shares proposed to be sold, the total
number of Voting Securities owned by the Investor, and the terms and conditions,
including without limitation price, of the Proposed Transfer. The Investor shall
also provide any other material facts relating to the Proposed Transfer which
may be reasonably requested by the Company. The First Refusal Offer shall
further state that the Company may acquire, in accordance with the provisions of
this Article, all or any part of the Offered Shares on terms and conditions,
including without limitation price, not less favorable to the Company than those
on which the Investor proposes to sell the Offered Shares to the Proposed
Transferee, including any deferred or installment payment provision.

                  (c) In the event the terms of the Proposed Transfer
contemplate the payment to the Investor of consideration other than cash, the
Fair Value of such non-cash consideration shall be determined in accordance with
Section 3.8 hereof.

         3.6 COMPANY'S RIGHT OF FIRST REFUSAL.

                  (a) If the Company desires to purchase all or any part of the
Offered Shares, the Company shall deliver a written notice of its election to
purchase to the Investor within 15 days after the date of receipt of the First
Refusal Offer by the Company. Such notice to purchase the Offered Shares, shall,
when taken in conjunction with the First Refusal Offer, be deemed to constitute
a valid, legally binding and enforceable agreement for the sale to, and purchase
by, the Company of the number of Offered Shares specified by the Company in such
notice and on the terms of the First Refusal Offer.

                  (b) The closing of the sale of Offered Shares to the Company
pursuant to this Section 3.6 shall be made at the offices of the Company on such
date as may be agreed upon by the Company and Investor, but no later than 45
days following the date the First Refusal Offer is received by the Company. Such
sale shall be effected by the Investor's delivery to the Company of a
certificate(s) evidencing the Offered Shares (or any portion thereof) to be
purchased by the Company, duly endorsed for transfer to the Company, against
payment to the Investor of the purchase price by the Company. The non-exercise
by the Company of its rights pursuant to this Section shall be without prejudice
to its rights under this Section 3.6 with respect to any future sales of Offered
Shares.

         3.7 SALES TO PROPOSED TRANSFEREE. In the absence of a valid election to
purchase, the Offered Shares may be sold by the Investor to the Proposed
Transferee at any time within 90


- --------------------------------------------------------------------------------
         Stockholder Agreement
         Execution Copy                 5


<PAGE>   8


days after the date of receipt of the First Refusal Offer by the Company. Any
such sale shall be at the same or greater price and upon other terms and
conditions, if any, not more favorable to the Proposed Transferee than those
specified in the First Refusal Offer. Any Offered Shares not sold within the
permitted time period shall continue to be subject to the requirements of a
prior offer and right of first refusal pursuant to this Article 3.

         3.8 DETERMINATION OF FAIR VALUE.

         For the purpose of this Agreement, Fair Value shall be determined as
follows:

                  (a) The Fair Value of any security then traded on any national
securities exchange or automated quotation system which has sale price
reporting, shall be the mean between the high and low sales prices, if any, on
such exchange or system on the date as of which Fair Value is being determined
or, if none, shall be determined by taking a weighted average of the means
between the highest and lowest sales prices on the nearest date before and the
nearest date after that date.

                  (b) If a security is then traded on an exchange or system
which does not have sale price reporting, the Fair Value of the security shall
be the mean between the average of the "bid" and the average the "ask" prices,
if any, as reported for such the date as of which Fair Value is being
determined, or, if none, shall be determined by taking a weighted average of the
means between the highest and lowest sales prices on the nearest date before and
the nearest date after such date.

                  (c) Fair Value for Voting Securities of the Company if it is
not publicly traded shall be determined by dividing the highest price (net of
total debt determined in accordance with generally accepted accounting
principles) for which the Company could be sold as a going concern to an
independent third party, assuming a reasonable time (up to 12 months) to
accomplish such sale by the number of fully diluted shares of Voting Securities
(calculated on an as converted basis, and assuming the exercise of all rights,
options, and warrants and conversion of all convertible securities) outstanding.
In order to determine the value for which the Company could be sold, the Company
and the Investor shall meet and use their best efforts to reach an agreement on
the Company's Fair Value. If such parties are unable to reach such agreement
within a reasonable amount of time, such parties will use their best efforts to
agree upon the selection of an independent appraiser or investment banking firm
of international standing within 30 business days after giving notice that
requires a determination of Fair Value. Such appraiser or investment banking
firm will have 30 business days in which to determine the Fair Value, and its
determination will be final and binding on all parties concerned. All costs of
such determination shall be borne equally by the parties.

                  (d) The Fair Value of any property other than cash or
securities offered as consideration by a Proposed Transferee for the Offered
Shares shall be the fair market value of such property. In order to determine
the fair market value of such property, the Company and the Investor shall meet
and use their best efforts to reach an agreement on the fair market value. If
such parties are unable to reach such agreement within a reasonable amount of
time, such parties will use their best efforts to agree upon the selection of an
independent appraiser within thirty business days after giving notice that
requires a determination of Fair Value. Such

<PAGE>   9


appraiser will have thirty business days in which to determine the Fair Value,
and this determination will be final and binding on all parties concerned. All
costs of such determination shall be borne equally by the parties.

ARTICLE 4. COVENANTS OF JENOPTIK

Jenoptik agrees as follows on behalf of itself and all members of the Jenoptik
Group to the extent permitted by applicable law:

         4.1 ACCESS TO INFORMATION ON PROJECTS.

                  (a) For as long as any member of the Jenoptik Group holds
Voting Securities, if any member of the Jenoptik Group is involved in providing
design, planning or other services with respect to the development of a
semi-conductor fabrication facility for any customer or potential customer,
Jenoptik with reasonably promptness shall provide notice to the Company, in
accordance with Section 6.2 hereof, including the following information:

                           (i) a general description of the proposed fabrication
facility;

                           (ii) the design or designs for such facility being
proposed by Jenoptik;

                           (iii) a description of the general types and
estimated number of pieces of equipment that will be required for the facility,
including any special capability, with particular reference to the types of
equipment or facilities then being offered by the Company or any of its
Affiliates; and

                           (iv) the estimated time schedule for construction of
the facility, ordering and delivery of equipment for such facility.

                  (b) Jenoptik shall provide the Company with a reasonable
opportunity to comment on the project for which it receives the notice and
information under paragraph (a) above and Jenoptik will continue to keep the
Company advised of the status of each such project as it progresses.

                  (c) The Jenoptik Group is not required to comply with this
Section 4.1 to the extent compliance would breach the Jenoptik Group's
confidentiality agreements. However, the Jenoptik Group shall use commercially
reasonable efforts to ensure that it will be permitted to comply with this
Section 4.1 in connection with any confidentiality agreements.

         4.2 PREFERRED SUPPLIER.

                  (a) For so long as any member of the Jenoptik Group holds

                           (i) Jenoptik Group shall specify the Company as a
preferred supplier;

                           (ii) If at any time any member of the Jenoptik Group
proposes to order from a third party products and applications similar to those
then offered by the Company or any Affiliate of the Company (the "Third Party
Proposal"), then the Jenoptik Group member shall first give the Company a
written notice (the "Jenoptik Offer") offering the Company, without

disclosing the identity of the third party, the opportunity to match the terms
and conditions of the Third Party Proposal. The Jenoptik Offer shall disclose
the terms and conditions of the Third Party Proposal and be delivered to the
Company in accordance with Section 6.2 hereof. If the Company desires to accept
the Jenoptik Offer, the Company shall deliver a written notice of its election
to accept the Jenoptik Offer within thirty days after the date of receipt of the
