Item 1. Security and Subject Company.
 
  The name of the subject company is AG Associates, Inc., a California
corporation (the "Company"). The address of the principal executive offices of
the Company is 4425 Fortran Drive, San Jose, California 95134-2300. The title
of the class of equity securities to which this Solicitation/Recommendation
Statement on Schedule 14D-9 (this "Schedule 14D-9") relates is the common
stock, no par value, of the Company (the "Shares").
 
Item 2. Tender Offer of the Bidder.
 
  This Schedule 14D-9 relates to the cash tender offer (the "Offer") by MIG
Acquisition Corporation, a Delaware corporation ("Purchaser"), which is a
wholly owned subsidiary of STEAG Electronic Systems GmbH, a German business
entity ("Parent"), to purchase all of the issued and outstanding Shares at
$5.50 per Share, net to the seller in cash, without interest. The Offer is
described in the Tender Offer Statement on Schedule 14D-1 dated January 22,
1999, filed with the Securities and Exchange Commission (the "Commission") by
Parent and Purchaser. The terms and conditions of the Offer are set forth in
Purchaser's Offer to Purchase dated January 22, 1999, and the related Letter
of Transmittal (which together with any amendments or supplements thereto
constitute the "Offer Documents").
 
  The Offer is being made pursuant to the Agreement and Plan of Merger dated
as of January 18, 1999 (the "Merger Agreement"), by and among Parent,
Purchaser and the Company. Pursuant to the Merger Agreement, as soon as
practicable after consummation of the Offer and satisfaction or waiver, if
permissible, of all conditions set forth in the Merger Agreement, Purchaser
will be merged with and into the Company (the "Merger" and, together with the
Offer and other transactions contemplated by the Merger Agreement, the
"Transactions"), and the Company will become a wholly owned subsidiary of
Parent. At the effective time of the Merger (the "Effective Time"), each Share
outstanding immediately prior to the Effective Time, other than Shares held
(a) by a subsidiary of the Company, (b) by Parent or Purchaser (including
Shares purchased by Purchaser in the Offer), and (c) by Dissenting
Shareholders (as defined herein), will be converted into the right to receive,
upon surrender of the certificate formerly representing such Share, $5.50 in
cash or any higher price paid for a Share in the Offer (the "Offer Price"),
without interest. See Item 3 of this Schedule 14D-9 for a summary of the
Merger Agreement.
 
  The Offer Documents indicate that the principal offices of Parent are
located at Ruttenscheider Strabe 1-3, 45128 Essen, Germany, and the principal
offices of Purchaser are located at c/o Morrison & Foerster LLP, 425 Market
Street, San Francisco, California 94105.
 
Item 3. Identity and Background.
 
  (a) This Schedule 14D-9 is being filed by the Company. The business address
of the Company is 4425 Fortran Drive, San Jose, California 95134-2300.
 
  (b)(i) Agreements with Executive Officers, Directors and Affiliates.
 
  The Company has entered into certain contracts, agreements, arrangements and
understandings with its executive officers, directors and affiliates, which
are described under the headings "Directors' Compensation," "Compensation of
Named Officers," "Employment Agreements" and "Certain Relationships and
Related Transactions" in the Company's proxy statement dated January 26, 1998,
relating to the Annual Meeting of Shareholders of the Company held on February
26, 1998. A copy of the above-referenced portions of such proxy statement is
filed as an Exhibit to this Schedule 14D-9.
 
  The Company has agreed with Parent and Purchaser to cause all outstanding
options to purchase Shares that were granted under the Company's stock option
plans to be terminated and cancelled as of or prior to the Effective Time. As
a result, the Company intends to enter into agreements and other arrangements
with the persons who currently hold options ("Option Holders"), some of whom
are executive officers, directors and affiliates of the
 
                                       1
<PAGE>
 
Company. In consideration of the termination or cancellation of the options,
on the date which is twelve months following the Effective Time (the "Payment
Date"), each Option Holder employed by the Company on the Payment Date, or who
was terminated by the Company without cause prior to the Payment Date, will
receive a cash bonus equal to the product of (i) the number of vested options
that otherwise would have been held by the Option Holder as of the Effective
Time and (ii) the difference between $10.00 and the exercise price per share
of such options; provided, however, that the aggregate amount that the Company
will agree to pay under such agreements will not exceed $2,040,000. If the
aggregate amount payable by the Company exceeds $2,040,000, any cash bonus
payable to an Option Holder will be reduced pro rata to the extent of such
excess. The Company also may take other actions it deems appropriate to cause
all outstanding options to be terminated and canceled as of or prior to the
Effective Time.
 
  (ii) Agreements of Parent with Certain Shareholders.
 
  Parent has entered into the following agreements with the persons known to
the Company to beneficially own more than 5% of the Shares outstanding at the
time of such agreements. The following are summaries of the material terms of
the agreements. These summaries are not complete descriptions of the terms and
conditions of the agreements and are qualified in their entirety by reference
to the full text of the agreement summarized. Each of the agreements
summarized below is incorporated by reference herein and a copy of each
agreement has been filed as an Exhibit to this Schedule 14D-9.
 
  Voting Agreements with Specified Shareholders.
 
  Concurrently with or prior to the execution of the Merger Agreement, Dr.
Arnon Gat, Chairman of the Board and Chief Executive Officer of the Company,
Anita Gat, Dr. Gat's spouse and Vice President of Administration, Director of
Corporate Communications and Secretary of the Company, Nippon Typewriter
Company Ltd., Clal Electronics Industries Ltd. and Canon Sales Co., Inc.
(collectively, the "Specified Shareholders"), which collectively held
approximately 2,293,071 Shares representing 37% of the Shares outstanding as
of January 15, 1999, each entered into a voting agreement (the "Specified
Voting Agreements") with Parent pursuant to which such shareholder agreed to
tender pursuant to the Offer the Shares held by such shareholder, and granted
an irrevocable proxy to Parent to vote at any meeting of the shareholders of
the Company all Shares owned by such shareholder (i) in favor of the Merger,
and (ii) against any action or agreement which would impede, interfere with or
prevent the Merger, including any other extraordinary corporate transaction,
such as a merger, reorganization or liquidation involving the Company and a
third party or any other proposal of a third party to acquire the Company.
 
  Pursuant to the Specified Voting Agreements, the Specified Shareholders
agreed not to (i) transfer, or consent to any transfer of, any or all of the
Shares or any interest therein held by them, (ii) enter into any contract,
option or other agreement or understanding with respect to any transfer of any
or all of the Shares or any interest therein held by them, (iii) grant any
proxy, power-of-attorney or other authorization or consent in or with respect
to the Shares held by them, or (iv) take any other action that would in any
way restrict, limit or interfere with the performance of their obligations
under the Specified Voting Agreements. Additionally, in the event of any stock
split, stock dividend, merger, reorganization, recapitalization or other
change in the capital structure of the Company affecting the outstanding
Shares, or the acquisition of additional Shares or other securities or rights
of the Company by any Specified Shareholder, the number of Shares subject to
the Specified Voting Agreements will be adjusted appropriately, and the
Specified Voting Agreements and the obligations thereunder will attach to any
additional Shares or other securities or rights of the Company issued to or
acquired by the Specified Shareholders.
 
  The Specified Voting Agreements contain various representations and
warranties of the parties thereto, including representations by each Specified
Shareholder as to such shareholder's record and beneficial ownership of the
Shares held by such shareholder, due corporate organization and authority (to
the extent the Specified Shareholder is a corporate entity) to enter into the
Specified Voting Agreements, due authorization to enter into and the
enforceability of the Specified Voting Agreements, and the absence of
conflicts and encumbrances on the Shares held by them.
 
                                       2
<PAGE>
 
  The Specified Voting Agreements provide that (i) from and after the date of
the Specified Voting Agreements to the Effective Time, each Specified
Shareholder will not, and will not permit the Company to, make any elections,
or change any existing elections, with respect to taxes, without the prior
written consent of Parent, and (ii) from and after the date that Purchaser
will have purchased and paid for all of the Shares of such Specified
Shareholder, such Specified Shareholder will make available to Parent any and
all records and other materials in such Specified Shareholder's possession or
control that relate to any of the Company's filings or returns relating to
taxes affecting the Company, or any other records relating to taxes of the
Company or for which the Company may be responsible.
 
  The Specified Voting Agreements, and all rights and obligations of the
parties thereunder, will terminate immediately upon the earlier of (i) the
date upon which the Merger Agreement is terminated in accordance with its
terms, or (ii) the date that Purchaser will have purchased and paid for all of
the Shares of such Specified Shareholder; provided, however, that the
covenants set forth in the Specified Voting Agreements will survive without
limitation. Additionally, the irrevocable proxy given pursuant to each
Specified Voting Agreement will be automatically revoked and be of no further
force or effect, without further action on the part of any party hereto,
immediately upon the termination of such Specified Voting Agreement.
 
  Voting Agreement with Poalim.
 
  Immediately prior to the execution of the Merger Agreement, Poalim
Investments Ltd. ("Poalim"), which then held approximately 559,228 Shares
delivered a letter to Parent (together with the Specified Voting Agreements,
the "Voting Agreements") pursuant to which Poalim agreed to tender 520,000 of
its Shares in the Offer representing 8% of the Shares outstanding as of
January 15, 1999. Additionally, Poalim has represented to Parent the number of
Shares Poalim beneficially owns and holds of record and has agreed that it
will not, at any time prior to June 30, 1999, transfer or consent to transfer
any of such Shares to any person, enter into any contract, option or agreement
with respect to such Shares it owns or take any action that would in any way
restrict, limit or interfere with the tendering of such Shares into the Offer.
Poalim also has granted its proxy (which is irrevocable prior to June 30,
1999) to Dr. Gat to vote 520,000 of Poalim's Shares in favor of the Merger and
against any action or agreement which would impede, interfere with or prevent
the Merger.
 
  (iii) Agreements with Parent and Purchaser.
 
  The Company has entered into the following contracts, agreements,
arrangements and understandings with Parent and/or Purchaser. The following
are summaries of the material terms of the agreements. These summaries are not
complete descriptions of the terms and conditions of the agreements and are
qualified in their entirety by reference to the full text of the agreement
summarized. Each of the agreements summarized below is incorporated by
reference herein and a copy of each agreement has been filed as an Exhibit to
this Schedule 14D-9.
 
  The Merger Agreement.
 
  The Merger Agreement provides for the acquisition of the Company by Parent
in a two-step process: the Offer followed by the Merger. If, upon purchase of
the Shares tendered in the Offer, Purchaser owns at least 90% of the Shares
then outstanding (the "Minimum Condition"), then Purchaser will be able to
approve the Merger without a meeting of the shareholders of the Company. If
the Minimum Condition is not met but more than 50% of the Shares then
outstanding are tendered to Purchaser pursuant to the Offer, Purchaser has
agreed to amend the Offer to reduce the number of Shares subject to the Offer
to the number of Shares equal to 49.9% of the Shares then outstanding (the
"Revised Minimum Number"). In such event, if a greater number of Shares is
tendered into the Offer and not withdrawn, Purchaser will purchase the Revised
Minimum Number of Shares on a pro rata basis. Following such purchase, the
Company would call a shareholders' meeting to vote on the Merger. Capitalized
terms not otherwise defined herein have the meanings set forth in the Merger
Agreement.
 
  The Offer. Purchaser is making the Offer to purchase the Shares, as required
by Article I of the Merger Agreement. The Merger Agreement provides that
Parent will cause Purchaser to commence the Offer as promptly as reasonably
practicable, but in no event later than five business days, after the date of
the public announcement
 
                                       3
<PAGE>
 
of the terms of the Merger Agreement. The obligation of Purchaser and Parent
to accept for payment, and pay for, the Shares tendered pursuant to the Offer
is subject to the satisfaction of (i) the Minimum Condition or Revised Minimum
Number of Shares prior to the expiration of the Offer, and (ii) certain other
conditions described in the Merger Agreement. Subject to the terms and
conditions of the Merger Agreement and the applicable regulations of the
Commission, Purchaser and Parent also expressly reserve the right, at any time
and from time to time, (i) to delay acceptance for payment of, or, regardless
of whether such Shares were accepted for payment, payment for, any Shares
pending receipt of any regulatory approval specified in the Merger Agreement,
(ii) to terminate the Offer and not accept for payment any Shares upon the
occurrence of any of the conditions specified in the Merger Agreement prior to
the expiration date of the Offer (the "Expiration Date"), and (iii) to delay,
terminate or waive the Minimum Condition or any other condition or otherwise
amend the Offer including extending the Expiration Date in any respect.
Furthermore, Purchaser will not (i) impose conditions in addition to those set
forth in the Merger Agreement, (ii) reduce the Offer Price or the number of
Shares sought in the Offer, or (iii) change the form of consideration payable
in the Offer.
 
  Notwithstanding any other provision contained in the Merger Agreement, in
the event the Minimum Condition is not satisfied on any scheduled Expiration
Date, Purchaser will either extend the Expiration Date or amend the Offer to
provide that, in the event (i) the Minimum Condition is not satisfied at the
next scheduled Expiration Date (after giving effect to the issuance of any
Shares issued under the Stock Option Agreement, as defined under the caption
"Stock Option Agreement" below), and (ii) the number of Shares tendered
pursuant to the Offer and not withdrawn as of such next scheduled Expiration
Date is more than 50% of then outstanding Shares, Purchaser will waive the
Minimum Condition, reduce the number of Shares subject to the Offer to the
Revised Minimum Number of Shares and, if a greater number of Shares is
tendered in the Offer and not withdrawn, purchase, on a pro rata basis, the
Revised Minimum Number of Shares (it being understood that Purchaser shall not
in any event be required to accept for payment, or pay for, any Shares if less
than the Revised Minimum Number of Shares are tendered pursuant to the Offer
and not withdrawn at the Expiration Date).
 
  The Merger. Following completion of the Offer, Purchaser will own either (i)
more than 90% of the Shares or (ii) 49.9% of the Shares. Purchaser then will
be merged with and into the Company, either pursuant to a short-form merger
under the provisions of the California General Corporation Law (the "CGCL") or
a vote of the Company's shareholders at a meeting. See "Shareholders Meeting"
below. At the Effective Time, the separate corporate existence of Purchaser
will cease and the Company will continue as the surviving corporation (the
"Surviving Corporation") and will become a wholly owned subsidiary of Parent.
In the Merger: (i) each share of common stock, $1.00 par value, of Purchaser
issued and outstanding will be converted into and become one fully paid and
nonassessable share of common stock of the Surviving Corporation; and (ii)
each Share issued and outstanding, other than Shares held (a) by a subsidiary
of the Company, (b) by Parent or Purchaser (including Shares purchased by
Purchaser in the Offer), and (c) by shareholders who have demanded and
perfected, and have not withdrawn or otherwise lost, dissenters' rights, if
any, under the CGCL ("Dissenting Shareholders"), will be cancelled and
converted automatically into the right to receive, upon surrender of the
certificate formerly representing such Share, an amount in cash, without
interest, equal to $5.50 or any higher price that may be paid per Share in the
Offer (the "Merger Consideration"). Shares as to which dissenters' rights have
been validly exercised pursuant to the CGCL will not be converted into the
right to receive the Merger Consideration, but will be entitled to payment of
the fair market value of such Shares in accordance with the provisions of
Chapter 13 of the CGCL.
 
  Board Representation. Following completion of the Offer, Purchaser will have
the right to appoint new directors of the Company. The Merger Agreement
provides that upon the purchase by Purchaser of such number of Shares
satisfying the Minimum Condition or the Revised Minimum Number of Shares
pursuant to the Offer, Purchaser will be entitled, at its option, to designate
such number of directors, rounded up to the next whole number, on the Board of
Directors of the Company (the "Board") as will give Purchaser representation
on the Board equal to the product of (i) the total number of directors on the
Board (giving effect to any increase or decrease in the number of directors
pursuant to the Merger Agreement), and (ii) the percentage that the aggregate
number of Shares beneficially owned by Purchaser (including Shares accepted
for payment) and Parent bears to the total number of Shares issued and
outstanding. The Company will, at such time, use its best efforts to cause
 
                                       4
<PAGE>
 
Purchaser's designees to be appointed or elected to the Board, and to
constitute the same percentage as such individuals represent on the Board of
(a) each committee of the Board (other than any committee of the Board
established to take action under the Merger Agreement), (b) each board of
directors of each Subsidiary, and (c) each committee of each such board.
Notwithstanding the foregoing, until the Effective Time, such Board will
include at least two directors who are directors on the date of the Merger
Agreement and who are not employees of the Company or any of its Subsidiaries
or affiliates of Parent or Purchaser.
 
  Parent or Purchaser will supply to the Company any information with respect
to itself and such nominees, officers, directors and affiliates required by
Section 14(f) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act") and Rule 14f-1 promulgated thereunder. Upon any request by
Purchaser, the Company will file with the Commission and transmit to the
record shareholders of the Company such information with respect to the
Company and its officers and directors and Purchaser's designees as is
necessary to enable Purchaser's designees to be elected to the Board.
 
  From and after the Effective Time, the directors and officers of Purchaser
at the Effective Time will become the directors and officers of the Surviving
Corporation.
 
  Charter Documents. The Merger Agreement provides that, at the Effective
Time, the Certificate of Incorporation of Purchaser, as in effect at the
Effective Time, will be the Articles of Incorporation of the Surviving
Corporation until thereafter amended in accordance with its provisions and as
provided by the CGCL. The Merger Agreement also provides that the Bylaws of
Purchaser, as in effect at the Effective Time, will be the Bylaws of the
Surviving Corporation until thereafter amended in accordance with its
provisions, the provisions of the Articles of Incorporation of the Surviving
Corporation and as provided by the CGCL.
 
  Shareholders Meeting. If Purchaser does not hold at least 90% of the Shares
following completion of the Offer, under the CGCL, the Merger cannot be
effected without a vote of the Company's shareholders. In such event, the
Company will as promptly as practicable following the acceptance for payment
and purchase of Shares by Purchaser pursuant to the Offer, duly call, give
notice of, convene and hold a meeting of its shareholders (the "Special
Meeting") for the purpose of approving the Merger and adopting the provisions
relating to the Merger in the Merger Agreement. The Company will use its best
efforts to solicit from its shareholders proxies in favor of the approval of
the Merger, and will take all other action necessary or advisable to secure
the vote or consent of its shareholders required by the CGCL, its Articles of
Incorporation and Bylaws, and to obtain such approvals, subject to applicable
fiduciary duties of the Board.
 
  Under the CGCL, if Purchaser or Parent acquire at least 90% of the Shares,
Purchaser will be able to approve the Merger without a vote of the Company's
shareholders. In the event Purchaser or Parent acquires at least 90% of the
Shares, and provided that the other conditions set forth in the Merger
Agreement have been satisfied or waived, Purchaser, Parent and, at the request
of Parent, the Company will take all necessary and appropriate action to cause
the Merger to become effective as soon as practicable after expiration or
termination of the Offer without a meeting of the Company's shareholders in
accordance with the CGCL.
 
  Proxy Statement. If approval of the Merger and adoption of the Merger
Agreement by the Company's shareholders is required by applicable law, the
Company will prepare and file a proxy statement (the "Proxy Statement") with
the Commission and the Company and Parent will cooperate in responding to any
comments of the Staff of the Commission and the Company will cause the Proxy
Statement to be mailed to its shareholders after responding to all such
comments to the satisfaction of the Staff of the Commission. The Proxy
Statement will, subject to the Board's fiduciary duties, include a
recommendation of the Board to vote in favor of the approval of the Merger and
the adoption of the provisions relating to the Merger in the Merger Agreement.
 
  Employee Benefits. Parent has agreed that for a period of twelve months from
the Effective Time, it will cause the Surviving Corporation to provide active
employees of the Company and its Subsidiaries with benefits (including,
without limitation, welfare benefits) that are reasonably comparable to the
benefits provided under the Company's benefit plans (other than equity-based
plans) as in effect immediately prior to the Effective Time.
 
                                       5
<PAGE>
 
Additionally, Parent will cause the Surviving Corporation to provide a two-
month paid sabbatical to certain employees as identified by the Company.
Parent will provide such sabbatical if the Surviving Corporation is merged
with, or transfers all of its assets to, Parent or an affiliate of Parent.
 
  Conduct of Business. Pursuant to the Merger Agreement, the Company has
covenanted and agreed that, prior to the Effective Time, unless Parent
otherwise consents in writing or as otherwise expressly contemplated by the
Merger Agreement, the business of the Company will be conducted only in the
ordinary course. Subject to the foregoing limitations, the Company has also
covenanted and agreed that:
 
    Governing Documents; Stock Splits; Redemptions; Issuances of Securities.
  The Company will not, directly or indirectly: (i) amend or propose to amend
  its Articles of Incorporation or Bylaws or reincorporate in any
  jurisdiction; (ii) split, combine or reclassify any issued and outstanding
  shares of its capital stock, or declare, set aside or pay any dividend or
  other distribution (payable in cash, stock, property or otherwise) with
  respect to such shares; (iii) redeem, purchase, acquire or offer to acquire
  (or permit any Subsidiary to redeem, purchase, acquire or offer to acquire)
  any shares of its capital stock; or (iv) issue, sell, pledge, accelerate,
  modify the terms of or dispose of, or agree to issue, sell, pledge,
  accelerate, modify the terms of or dispose of, any additional shares of, or
  securities convertible or exchangeable for, or any options, warrants,
  calls, commitments or rights of any kind to acquire any shares of, its
  capital stock of any class or other property or assets, provided, that the
  Company (a) may issue Shares upon the exercise of options outstanding as of
  the date of the Merger Agreement, (b) may grant options under its 1993
  Employee Stock Option Plan to any new employee in amounts consistent with
  past practices, and (c) may enter into certain agreements or arrangements
  contemplated by the Merger Agreement.
 
    Dispositions; Acquisitions; Discharge of Liabilities; Settlement of
  Litigation. The Company will not (i) transfer, lease, license, sell,
  mortgage, pledge, dispose of or encumber any material assets, except in the
  ordinary course of business consistent with past practice, (ii) acquire (by
  merger, consolidation or acquisition of stock or assets) any corporation,
  partnership or other business organization or division thereof or any
  material assets, (iii) enter into or modify any material contract, lease,
  agreement or commitment, except in the ordinary course of business
  consistent with past practice, (iv) terminate, modify, assign, waive,
  release or relinquish any material rights or claims or amend any material
  rights or claims not in the ordinary course of business consistent with
  past practice, (v) pay, discharge or satisfy any material claims,
  liabilities or obligations, other than the payment, discharge or
  satisfaction of any such claims, liabilities or obligations, in the
  ordinary course of business, reflected or reserved against in, or
  contemplated by, the consolidated financial statements of the Company
  included in reports and registration statements filed with the Commission
  (the "SEC Reports"), or (vi) settle or compromise any material claim,
  action, suit or proceeding pending or threatened against it, or, if the
  Company may be liable or obligated to provide indemnification, against its
  directors or officers, before any court, governmental agency or arbitrator.
 
    Indebtedness. Except as provided in the Merger Agreement, the Company
  will not (i) incur or adversely modify any material indebtedness or other
  liability; provided, however, that the Company will be permitted to draw
  upon its existing credit lines as it may deem appropriate, (ii) assume,
  guarantee, endorse or otherwise become liable or responsible (directly or
  indirectly, contingent or otherwise) for the obligations of any other
  person, or (iii) make any loans, advances or capital contributions to, or
  investments in, any other person (other than to wholly owned Subsidiaries
  or customary loans or advances to employees in the ordinary course of
  business consistent with past practice).
 
    Employee Compensation. The Company will not grant any increase in the
  salary or other compensation of its employees, or grant any bonus to any
  employee or enter into any employment agreement or make any loan to or
  enter into any material transaction of any other nature with any employee
  of the Company or any Subsidiary, except in the ordinary course of business

  Merger Agreement or as may be required by applicable law or regulation or,
  in the case of employees who are not executive officers of
 
                                       6
<PAGE>
 
  the Company, in the ordinary course of business consistent with past
  practices (i) adopt, increase, accelerate the vesting of or payment of any
  amounts in respect of, or otherwise amend, in any respect, any collective
  bargaining, bonus, profit sharing, incentive or other compensation, stock
  option, stock purchase or restricted stock, insurance, pension, retirement,
  deferred compensation, employment or other employee benefit plan,
  agreement, trust, fund, plan or arrangement for the benefit or welfare of

  methods without providing advance notice to Parent in writing.
 
    Tax Elections. The Company will not make any tax election (other than in
  the ordinary course of preparing and filing its tax returns) or settle or
  compromise any tax liability or investigation.
 
    Company Relationships with Suppliers and Customers; Participation in
  Meetings. The Company will use its reasonable efforts, to the extent not
  prohibited by the Merger Agreement, to maintain its relationships with its
  suppliers, customers and employees, and, if and as requested by Parent or
  Purchaser, (i) to the extent permitted by applicable law, the Company will
  use its reasonable best efforts to make reasonable arrangements for
  representatives of Parent or Purchaser to meet with customers and suppliers
  of the Company or any Subsidiary, and (ii) the Company will schedule, and
  the management of the Company will participate to the extent requested in,
  meetings of representatives of Parent or Purchaser with employees of the
  Company or any Subsidiary.
 
  Access to Information. Subject to the requirements of any binding
confidentiality agreements with customers and subject to any applicable
limitations imposed by law, the Company will, prior to the Effective Time,
afford Parent reasonable access during regular business hours to its officers,
employees, agents, properties, books, records and work papers, and will
furnish Parent all financial, operating and other information and data as
Parent may reasonably request, provided, that in the event such access or the
furnishing of such information is prohibited or limited due to binding
customer agreements or applicable law, the Company will inform Parent and use
its reasonable best efforts to obtain any necessary consent to allow such
access or to provide such information. Additionally, Parent, Purchaser and the
Company agree that the confidentiality provisions agreed to in the Mutual Non-
Disclosure Agreement, dated as of August 6, 1998, as amended (the "Mutual Non-
Disclosure Agreement"), will remain binding and in full force and effect in
accordance with the terms of such agreement.
 
  Consents and Approvals. Each of the Company, Parent and Purchaser will take
all reasonable actions necessary to comply with all legal requirements which
may be imposed on it with respect to the Merger Agreement, the Stock Option
Agreement, the Common Stock Option (as defined under the caption "Common Stock
Option" below) and the Transactions and will cooperate with and furnish
information to each other in connection with any such requirements imposed on
any of them or their respective subsidiaries. Subject to the terms and
conditions of the Merger Agreement, the Company, Parent and Purchaser will use
all commercially reasonable efforts to take, or cause to be taken, all action
and to do, or cause to be done, all things necessary, proper or advisable to
consummate and make effective as promptly as practicable the Transactions,
including, without limitation, using all commercially reasonable efforts to
obtain all necessary waivers, consents and approvals. Nothing in the Merger
Agreement will require Parent or Purchaser to agree to make, or to permit the
Company to make, any divestiture of or grant any rights to a significant asset
in order to obtain any waiver, consent or approval.
 
  Shareholder Litigation. The Company will give Parent the opportunity to
participate in the defense and settlement of any shareholder litigation
against the Company or its directors or officers relating to any of the
Transactions and will not enter into any such settlement without Parent's
consent, which consent may not be unreasonably withheld.
 
  Non-Solicitation. Neither the Company nor its officers, directors or
representatives, or any of their respective affiliates will initiate, solicit
or encourage, directly or indirectly, or take any action to facilitate
inquiries or the making of any proposal with respect to or participation in
negotiations concerning any proposal with respect to
 
                                       7
<PAGE>
 
or participation in negotiations concerning any merger, consolidation,
acquisition of more than two percent of the capital stock of the Company, a
business combination involving the Company or the purchase of all or a
significant portion of the assets of the Company (an "Alternative
Transaction"), except that the Board may provide information to any third
person making a bona fide, written and unsolicited inquiry concerning an
Alternative Transaction that would result in the payment to the Company
shareholders of a higher price per share in cash than the Offer Price (a
"Superior Proposal"), provided that counsel to the Company has advised the
Board in writing that its fiduciary duties require it to consider the Superior
Proposal.
 
  The Merger Agreement provides that the Company will immediately notify
Parent if any proposal, offer, inquiry or other contact is received by, any
information is requested from, or any discussions or negotiations are sought
to be initiated or continued with, the Company by or from any person,
corporation, entity or "group" (as defined in Section 13(d) of the Exchange
Act) other than Parent and its affiliates, representatives and agents (each, a
"Third Party") in connection with any Alternative Transaction, and will, in
any such notice to Parent, indicate the identity of the Third Party and the
terms and conditions of any proposals or offers or the nature of any inquiries
or contacts, and thereafter will keep Parent informed, on a current basis, of
the status and terms of any such proposals or offers and the status of any
such discussions or negotiations. The Company will provide Parent with not
less than two Business Days' (defined as a weekday other than a public holiday
in the U.S. or Germany) notice prior to executing any definitive agreement
with respect to any Alternative Transaction or any public announcement
relating to any Alternative Transaction. Prior to furnishing any non-public
information to, or entering into negotiations with, any Third Party, the
Company will obtain an executed confidentiality agreement from such Third
Party on terms substantially the same as, or no less favorable to the Company
in any material respect than, those contained in the Mutual Non-Disclosure
Agreement. The Company will not release any Third Party from, or waive any
provision of, any such confidentiality agreement or any other confidentiality
or standstill agreement to which the Company is a party.
 
  Indemnification. The Merger Agreement provides that, subject to certain
limitations set forth therein, and subject to applicable law, for a period of
not less than four years from and after the Effective Time, the Surviving
Corporation (or any successor) will indemnify, defend and hold harmless the
present and former directors, officers, employees and agents of the Company
and its Subsidiaries against all losses, claims, damages, liabilities, fees,
costs and expenses (including reasonable fees and disbursements of counsel
approved by the Surviving Corporation in advance of disposition of judgments,
fines, losses, claims, liabilities and amounts paid in settlement (provided
that any such settlement is effected with the written consent of Parent or the
Surviving Corporation)) based in whole or in part on the fact that such person
is or was such a director, officer, employee or agent and arising out of
actions or omissions occurring at or prior to the Effective Time to the full
extent provided under the Company's Articles of Incorporation, Bylaws and
indemnification agreements as in effect on the date of the Merger Agreement
(including provisions relating to the advancement of expenses incurred in the
defense of any action or suit).
 
  Representations and Warranties. The Merger Agreement contains various
customary representations and warranties of the parties thereto including
representations by the Company as to its corporate organization and
qualification, its Subsidiaries, charter documents, capitalization, authority,
conflicts, consents, filings with the Commission and other governmental
authorities, compliance with applicable laws, required permits, SEC Reports,

approvals, brokers, financing, and information supplied to the Company.

permanent injunction or other order, decree or ruling issued by any court of

the Stock Option Agreement and the Voting Agreements may be terminated and the
Merger abandoned at any time prior to the Effective Time: (i) by mutual
written consent of Parent and the Company; (ii) by either Parent or the
Company, if (a) any Governmental Authority will have issued an order, decree
or ruling or taken any other action, in each case permanently restraining,

Transactions and such order, decree, ruling or other action will have become
final and non-appealable, or (b) the Merger will not have been completed by
June 30, 1999; (iii) by Parent, if (a) the Offer is terminated or expires
without the purchase of any Shares, unless such termination or expiration has

the Merger Agreement, (c) Parent and Purchaser will have failed to commence

                                       9
<PAGE>
 
written advice from legal counsel to the Board, that the failure to take such
action as described in the preceding clause (v)(a) would cause the Board to
violate its fiduciary duties to the Company's shareholders under applicable
law; and (c) given notice to Parent and Purchaser of its intent to terminate
the Merger Agreement and of the terms and conditions of the Alternative

  In the event of the termination of the Merger Agreement, the Common Stock
Option, the Stock Option Agreement or the Voting Agreements and the
abandonment of the Merger all strictly pursuant to the preceding paragraph,
such agreements will thereafter become void and have no effect, and no party
will have any liability to any other party or its shareholders or directors or
officers in respect thereof, except that nothing in the Merger Agreement will
relieve any party from liability for any willful breach of the Merger
Agreement. If Parent terminates the Merger Agreement, the Stock Option
Agreement or the Voting Agreements pursuant to the previous paragraph, or if
the Company terminates the Merger Agreement pursuant to the previous
paragraph, then the Company will pay to Parent, on the second business day
following any such termination, an amount equal to $1,023,000.
 
  Costs and Expenses. All costs and expenses incurred in connection with the
Merger Agreement and the Transactions will be paid by the party incurring such
costs and expenses, except that Parent and the Company will each pay one half
of the costs incurred in printing and distributing the Proxy Statement, if
any.
 
  Stock Option Agreement.
 
  Pursuant to a Stock Option Agreement between the Company, Parent and
Purchaser, dated as of January 18, 1999 (the "Stock Option Agreement"), the
Company granted to Purchaser an irrevocable option (the "Stock Option") to
purchase up to the number of Shares (the "Option Shares") that, when added to
the number of Shares owned by Purchaser and its affiliates following the
Offer, would equal 90% of the Shares then outstanding, at a cash purchase
price of $5.50 per Option Share, subject to the terms and conditions set forth
in the Stock Option Agreement; provided, however, that the Stock Option will
not be exercisable if (i) less than 80% of the Shares then outstanding has
been tendered upon the Expiration Date, and (ii) the number of Shares subject
thereto exceeds the number of authorized Shares available for issuance.
 
  The Stock Option Agreement provides that, subject to the conditions set
forth in the Stock Option Agreement and to any additional requirements of law,
the Stock Option may be exercised by Purchaser, in whole but not in part, at
any time or from time to time after the occurrence of an Exercise Event (as
defined below) and prior to the Termination Date (as defined below). For the
purpose of the Stock Option Agreement, an "Exercise Event" would occur if at
least 80% of the Shares then outstanding have been tendered upon the
Expiration Date, and the "Termination Date" would occur upon the first to
occur of any of the following: (i) the Effective Time; (ii) the date which is
10 business days after the occurrence of an Exercise Event (unless prior
thereto the Stock Option has been exercised); or (iii) the termination of the
Merger Agreement.
 
  The Stock Option Agreement provides that the obligation of the Company to
deliver Option Shares upon any exercise of the Stock Option is subject to the
following conditions: (i) such delivery would not in any material respect
violate, or otherwise cause the material violation of, Rule 4460(i)(1) of the
National Association of Securities Dealers Manual ("Rule 4460") or any
material applicable law, including, without limitation, the HSR Act,
applicable thereto; (ii) no preliminary or permanent injunction or other
final, nonappealable judgment by a court of competent jurisdiction preventing
or prohibiting such exercise of such Stock Option or the delivery of the
Option Shares; and (iii) the Company has available from its authorized Shares
such number of Shares as is sufficient to issue the Option Shares; provided,
however, that the Company will have fully complied with its obligations under
Rule 4460.
 
  The Stock Option Agreement contains various representations and warranties
of the parties thereto, including representations by the Company as to the
Company's corporate organization and authority relative to the Stock Option
Agreement, the Company's authority to issue the Option Shares and the absence
of any conflicts and the obtaining of all applicable filings and consents.
 
                                      10

  The Stock Option Agreement, other than certain obligations of the parties
specified in the Stock Option Agreement, will terminate on the Termination
Date.
 
  Loan to the Company.
 
  Subject to the limitations set forth in the Merger Agreement, in the event
that the Merger is not consummated on or before March 5, 1999, Parent will
make a loan to the Company (the "Loan") in the aggregate principal sum of
$3,000,000 (the "Principal"). Interest on the Principal will accrue at a
floating rate per annum equal to the internal rate of interest assessed by
Parent or its affiliates on intercorporate loans made to or among subsidiaries
of Parent (the "Interest"). All Principal and accrued Interest will become due
and payable two years from the date the Loan is made (the "Maturity Date").
Parent will not, however, be obligated to make the Loan if (i) the Offer has
not expired by its terms or, if the Offer has expired, the Shares tendered in
the Offer are insufficient to satisfy the Minimum Condition or the Revised
Minimum Number, (ii) any shareholder of the Company defaults under the Voting
Agreements, (iii) the Merger Agreement is terminated by Parent because the
Company has failed to comply in any material respect with any covenant or
obligation of the Merger Agreement, (iv) any representation or warranty made
by the Company under the Merger Agreement, the Common Stock Option or the
Stock Option Agreement is untrue at the time such representation or warranty
was made or is untrue on the date the Loan is made and such breach is caused
by an event that would constitute a Material Adverse Effect (as defined in the
Merger Agreement), (v) there is any preliminary or permanent injunction or
other order, decree or ruling issued by any court of competent jurisdiction or
any statute, rule, regulation or order entered, promulgated or enacted by any
governmental, regulatory or administrative agency or authority in effect that
would impact the effective operation of the business of the Company resulting
in a Material Adverse Effect from and after the Effective Time, (vi) any
waiting period under the HSR Act applicable to the purchase of Shares pursuant
to the Offer has not expired or terminated and the satisfaction of any
applicable foreign competition and antitrust statutes and regulations

(vii) there is pending any proceeding or litigation, initiated prior to or
after the date of the Merger Agreement, challenging the Merger or seeking to
prohibit, alter, prevent or materially delay the Merger, (viii) there is
pending or threatened against the Company any claim, action, suit, proceeding
or investigation which would or could reasonably be expected to have a
Material Adverse Effect, or (ix) the Company has terminated the Merger
Agreement prior to acceptance for payment of the Shares by Purchaser under the
Offer, and the Company has done each of the following: (a) entered into a
definitive written agreement with respect to an Alternative Transaction with a
third party; (b) determined, after receipt of written advice from legal
counsel to the Board that the failure to take such action as described in the
preceding clause (a) would cause the Board to violate its fiduciary duties to
the Company's shareholders under applicable law; and (c) given a notice to
Parent and Purchaser of its intent to terminate the Merger Agreement and of
the terms and conditions of the Alternative Transaction, and such notice was
given at least five Business Days prior to the date of termination of the
Merger Agreement.
 
  Common Stock Option.
 
  The Company granted to Parent an option (the "Common Stock Option") to
purchase an aggregate of 600,000 Shares at an exercise price of $2.00 per
share. The Common Stock Option will become exercisable as to 100,000 Shares if
and when the Loan is made by Parent to the Company. The remainder of the
Common Stock Option will become exercisable if and when a default occurs under
the Loan. The Common Stock Option will expire on March 5, 1999 (if the Loan is
not made) or on the first anniversary of the Maturity Date. The Company will
adjust the number of Shares subject to the Common Stock Option to maintain the
percentage of Shares subject to the Common Stock Option at the date of the
Merger Agreement if the Company causes or effects (i) a subdivision or
combination on its capital stock, (ii) a stock distribution or dividend on its
capital stock, or (iii) a recapitalization or reclassification of its capital
stock.
 
  AGI Option.
 
  Concurrently with the signing of the Merger Agreement, the Company and
Parent agreed to an option (the "AGI Option"). Pursuant to the AGI Option, if
(a) Parent shall purchase all of the ordinary and preferred shares
 
                                      11
<PAGE>
 
of AG Associates (Israel) Ltd., an entity formed under the laws of Israel (the
"Israeli Affiliate") that are not owned by the Company, (b) the closing of the
Merger does not occur, and (c) the Merger Agreement is terminated (the date on
which (a),  (b) and (c) will occur, the "Effective Date of the AGI Option"),
Parent will have the right to purchase, and the Company will be required to
sell, all but not less than all of the ordinary shares of the Israeli
Affiliate (as such number of shares may be increased or decreased as described
below) held by the Company (the "AGI Shares") for the aggregate purchase price
of $5,404,770 (the "AGI Purchase Price"), and the Company will have the right
to sell to Parent, and Parent will be required to purchase, all but not less
than all of the AGI Shares at the AGI Purchase Price (in either case, the
"Sale"), on the terms and subject to the conditions set forth therein. If the
Israeli Affiliate causes the AGI Shares to be subdivided or combined into a
greater or smaller number of shares, then the term "AGI Shares" herein shall
refer to such subdivided or combined shares and the AGI Purchase Price shall
remain the same.
 
  If either Parent or the Company elects to effect a Sale, written notice must
be sent to a trustee on or prior to the date which is 30 days following the
Effective Date of the AGI Option (the "Expiration Date of the AGI Option").
Additionally, the Company will not sell, pledge or otherwise transfer any of
the AGI Shares to any person other than Parent or one of Parent's affiliates
prior to the Expiration Date of the AGI Option, unless Parent shall have given
its prior written consent.
 
  The AGI Option contains various representations and warranties of the
Company, including representations by the Company as to the due authorization
and valid issuance of the ordinary shares of the Israeli Affiliate, the
absence of liens and encumbrances on the AGI Shares, the Company's authority
to issue the AGI Option, the enforceability of the AGI Option and the absence
of any conflicts with the Company's corporate charter documents, laws or other
agreements.
 
Item 4. The Solicitation or Recommendation.
 
  (a) The Board has unanimously approved the Merger Agreement and related
agreements, the Offer, the Merger and the other Transactions. The Board has
determined that the Merger Agreement and the Transactions (including the Offer
and the Merger) are fair to and in the best interest of the Company's
shareholders. The Board recommends that the Company's shareholders tender
their Shares to Purchaser pursuant to the Offer.
 
  (b) Background of the Offer; Reasons for the Recommendation.
 
  On January 30, 1998, the executive officers of the Company and Cecil Parker,
a consultant and director of the Company, met to analyze and discuss the
continued viability of the Company as an independent entity.
 
  On February 26, 1998, Dr. Arnon Gat, Chief Executive Officer of the Company,
presented to the Board the executive officers' recommendation, based in large
part on the January 30, 1998 meeting, that the Company seek a strategic
partner or acquirer. The Board authorized the executive officers of the
Company to engage an investment bank as its financial advisor and to enter
into discussions with potential strategic partners and acquirers.
 
  On March 25, 1998, the executive officers of the Company held an all day
strategic meeting, at which the executive officers affirmed their
recommendation to seek a strategic partner or acquirer. The executive officers
also determined that it would be in the Company's interests to continue to
invest heavily in research and development projects, so as to make the Company
more attractive to a potential strategic partner or acquirer.
 
  During March and April 1998, executive officers of the Company and the Board
met with representatives of three investment banking firms with respect to
engaging one of such firms in connection with the search for a strategic
partner or acquirer. At a meeting of the Board on April 24, 1998, the Board
determined not to select an investment banking firm at that time and directed
Dr. Gat to spearhead the effort to identify and evaluate opportunities to
maximize shareholder value and improve the viability of the Company.
 
  Following the April 24, 1998 meeting of the Board, Dr. Gat initiated and
engaged in detailed discussions with representatives of several companies that
Dr. Gat considered to be potential strategic partners or acquirers
 
                                      12
<PAGE>
 
for the Company. On May 12, 1998, Dr. Gat met with a number of executive
officers of one potential acquirer (the "First Prospect").
 
  On May 26, 1998, a special meeting of the Board was held, at which Dr. Gat
reported to the Board on the progress of the effort to identify and evaluate
opportunities to maximize shareholder value and improve the viability of the
Company. Dr. Gat and Mr. Parker indicated to the Board that a number of
companies that were contacted during April and May 1998 were not interested in
a strategic partnership or business combination with the Company.
 
  Following the May 26, 1998 meeting of the Board, Dr. Gat continued to engage
in detailed discussions with, and to give presentations to, representatives of
potential strategic partners or acquirers for the Company, including the First
Prospect.
 
  On June 4, 1998, representatives of the First Prospect met with Dr. Gat,
Julio L. Guardado, President and Chief Operating Officer of the Company, Kirk
W. Johnson, Vice President, Finance and Chief Financial Officer of the
Company, and Randhir Thakur, Vice President, Technology and Research &
Development, at the Company's offices in San Jose, principally to conduct
technical due diligence on the Company's products.
 
  On June 8, 1998, Dr. Gat met in Massachusetts with representatives of
another potential acquirer (the "Second Prospect").
 
  On June 19, 1998, Dr. Gat met with representatives of SoundView with respect
to Dr. Gat's efforts to find a strategic partner or acquirer, or to raise
capital, for the Company. Dr. Gat identified the First Prospect, the Second
Prospect and one other company (none of which was Parent) which he viewed as
potential strategic partners or acquirers for the Company, based on his
conversations with such companies.
 
  On June 22, 1998, representatives of the First Prospect met with Dr. Gat and
Messrs. Guardado and Johnson to discuss the Company's customer relationships
and financial forecasts.
 
  On June 25, 1998, the Company and SoundView entered into an engagement
agreement pursuant to which the Company hired SoundView as its exclusive
financial advisor in connection with the Company's search for a strategic
partner or acquirer. On June 29, 1998, SoundView advised the Company that the
First Prospect had engaged an investment banking firm to represent the First
Prospect in connection with a possible business combination with the Company.
 
  On July 8, 1998, Dr. Gat met with the chief executive officer and president,
and the executive vice president of the First Prospect. The executive officers
of the First Prospect expressed strong interest in pursuing a business
combination with the Company.
 
  On July 9, 1998, representatives of SoundView held conference calls with
executive officers of three companies (none of which was Parent or the
companies identified by Dr. Gat on June 19, 1998) with respect to a possible
business combination with the Company.
 
  On July 10, 1998, SoundView distributed to seven companies a confidential
memorandum relating to the Company, its business and its financial results and
prospects. On July 15, 1998, SoundView signed a confidentiality agreement with
the Second Prospect and delivered to such company a copy of the confidential
memorandum.
 
  On July 14 and 15, 1998, during the SEMICON/West conference in San
Francisco, California, Dr. Gat met with executive officers of each of the
companies (except for the Second Prospect) that had received the confidential
memorandum from SoundView, and Dr. Hans-Georg Betz, Chief Executive Officer of
Parent. Each of the executives that met with Dr. Gat expressed interest in
exploring a potential business combination with the Company.
 
  On July 16 and 17, 1998, the First Prospect engaged in comprehensive due
diligence, led by the First Prospect's investment bankers, with respect to
several aspects of the Company's business, operations and prospects.
 
                                      13
<PAGE>
 
  On July 17, 1998, SoundView delivered to Parent a copy of the confidential
memorandum relating to the Company.
 
  On July 22, 1998, SoundView sent a letter to Dr. Betz, describing certain
structures for a business combination between Parent and the Company.
 
  At a meeting of the Board on July 23, 1998, a representative of SoundView
reported to the Board on the firm's progress with respect to identifying an
acquirer for the Company. The representative of SoundView advised that recent
valuations of and premiums paid for comparable companies suggested that a
potential acquirer likely would offer the Company's shareholders approximately
$4.00 per Share. On July 23, 1998, the closing price for the Shares, as
reported on the Nasdaq National Market ("NASDAQ"), was $2.75 per Share.
 
  On July 30, 1998, Dr. Gat and Messrs. Guardado, Johnson and Thakur met with
representatives of the Second Prospect at the Company's offices in San Jose to
discuss general business issues, including valuation of the Company. The
representatives of the Second Prospect also toured the Company's manufacturing
facility.
 
  On July 31, 1998 and August 3, 1998, Mr. Hans-Joachim Wolf, Chief Financial
Officer of Parent, contacted Mr. Johnson to schedule preliminary due diligence
of the Company.
 
  From August 2 to 5, 1998, Dr. Gat and a representative of SoundView engaged
in a series of meetings in Japan with executive officers of the First
Prospect. A representative of Clal Electronics Industries Ltd. ("Clal
Electronics"), a holder of approximately 9% of the outstanding Shares, and
representatives of the investment banking firm engaged by the First Prospect
attended the meetings held on August 4, 1998.
 
  On August 6, 1998, Parent signed a mutual non-disclosure agreement with the
Company. On August 6 and 7, 1998, Parent, together with its advisors and
auditors, met and conducted preliminary due diligence at the Company, which
included presentations by management of the Company and a tour of the
Company's plant in San Jose. Representatives of SoundView also were present at
such meeting.
 
  At a telephonic meeting of the Board on August 6, 1998, Dr. Gat and a
representative of SoundView reported to the Board on the status of discussions
with the companies that had met with Dr. Gat at SEMICON/West on July 14 and
15, 1998. Dr. Gat indicated that the First Prospect and Parent were continuing
to conduct due diligence with respect to the Company, that one other company
remained moderately interested in pursuing a business combination with the
Company but was still assessing the risks and financial advantages of a
transaction with the Company, that two of the other companies had indicated
that they were not interested in pursuing a business combination with the
Company and that one of the companies was interested in pursuing a transaction
with the Company, but would make an offer to the Company and its shareholders
at a price per share approximately equal to the then current market price of
the Shares. On August 6, 1998, the closing price for the Shares, as reported
on NASDAQ, was $3.1875 per Share.
 
  From August 8 to September 8, 1998, Dr. Gat and representatives of SoundView
continued to respond to, and engage in meetings with respect to, technical,
legal and financial due diligence requests from the First Prospect, the Second
Prospect and Parent.
 
  On August 21, 1998, an executive officer of the First Prospect advised that
the board of directors of the First Prospect had authorized management to
effect a cash tender offer for the outstanding Shares. In addition, on the
same day, Dr. Gat and a representative of SoundView held a conference call
with representatives of the Second Prospect. Representatives of the Second
Prospect requested a live demonstration of the Company's Starfire products,
which demonstration was conducted on August 26 and 27, 1998.
 
  On August 22, 1998, the First Prospect terminated discussions with the
Company with respect to its proposed cash tender offer, citing "internal
factors."
 
  At a meeting of the Board on August 24, 1998, Dr. Gat and a representative
of SoundView reported to the Board on the status of discussions with the First
Prospect, the Second Prospect and Parent. Dr. Gat and the representative from
SoundView indicated that the First Prospect was not expected to continue to
pursue a
 
                                      14
<PAGE>
 
business combination with the Company, that the Second Prospect was continuing
its due diligence and likely would make a bid to acquire the Company during
the week of September 7, 1998, and that Parent likely would make a bid to
acquire the Company, although no time frame was estimated.
 
  On September 4, 1998, an executive officer of the Second Prospect advised
SoundView that the Second Prospect was not interested in pursuing a business
combination with the Company and that the executive officer would not be
presenting such possibility to the Second Prospect's board of directors.
 
  On September 8 and 9, 1998, Messrs. Guardado and Johnson met with Dr. Rolf
Thaler and Dr. Berthold Lutke-Daldrup, representatives of Parent, and a
representative of Harris Roja Corporation ("Harris Roja"), an investment
banking firm engaged by Parent to advise it in connection with the proposed
business combination with the Company, to discuss business issues and possible
transaction structures. Representatives of SoundView also participated in such
meetings. At such meetings, actual and forecast data of the Company and STEAG
AST Elektronik GmbH ("AST"), a wholly owned subsidiary of Parent which
designs, manufactures and distributes rapid thermal processing (RTP) systems,
were presented and discussed.
 
  From September 12 to October 19, 1998, representatives of the Company,
SoundView, Parent and Harris Roja continued to discuss possible transaction
structures, including a cash tender offer and a merger whereby Parent would
hold a majority of the then outstanding Shares and the remaining Shares would
continue to be held by the Company's public shareholders. During such period,
the closing prices of the Shares, as reported on NASDAQ, ranged between $2.00
and $2.875 per Share.
 
  On October 1, 1998, Clal Electronics sent a letter to the First Prospect
proposing that the First Prospect acquire a minority interest in the Company,
together with a one-year option to purchase additional Shares. The First
Prospect did not respond to Clal Electronic's letter.
 
  On October 8 and 9, 1998, Dr. Gat and Messrs. Johnson and Guardado visited
AST in Dornstadt, Germany. Management of AST gave a presentation which
included actual and projected financials of AST. The visit also included a
tour of the AST plant.
 
  On October 12, 1998, members of the management of Parent and a
representative of Harris Roja met with representatives of the Company and
SoundView in Essen, Germany. At the meeting the parties discussed alternative
transaction structures and the range of valuation ratios between the Company
and AST.
 
  On October 13, 1998, Dr. Gat and Mendy Erad, Chief Executive Officer of Clal
Electronics, met in Essen, Germany with representatives of STEAG
Aktiengesellschaft, a corporation organized under the laws of the Federal
Republic of Germany ("STEAG"), to discuss issues relating to the existing
contractual relationship between the Company and the Israeli Affiliate. Clal
Electronics is a shareholder of the Israeli Affiliate.
 
  STEAG held a management board meeting on October 16, 1998. After that
meeting, Dr. Betz discussed with Dr. Gat the range of valuation ratios between
the Company and AST that might be acceptable to Parent. Dr. Betz stated that
STEAG would consider proposing a cash tender offer of $5.50 per Share, subject
to a satisfactory resolution of certain due diligence issues.
 
  At a meeting of the Board on October 22, 1998, Dr. Gat and a representative
from SoundView reported to the Board on the status of discussions with the
First Prospect, the Second Prospect, Parent and one other potential acquirer.
Dr. Gat and the representative from SoundView indicated that the First
Prospect and the Second Prospect would not be pursuing any business
transaction with or investment in the Company, that one other company that had
expressed interest in acquiring the Company remained interested in pursuing a
transaction with the Company but would offer the Company and its shareholders
a small or no premium over the market price of the Shares, and that Parent had
offered to effect either a cash tender offer at $5.50 per Share or a merger
(which also valued the Shares at approximately $5.50 per Share) whereby Parent
would acquire a majority of the Shares. The representative from SoundView
provided the Board with various financial analyses reflecting the relative
 
                                      15
<PAGE>
 
advantages of a cash tender offer over the proposed merger and expressed
SoundView's opinion that the proposed cash tender offer would be more
advantageous to the shareholders of the Company than the proposed merger. The
Board and the representative from SoundView discussed some of the business and
strategic issues that would need to be addressed if the Company determined to
pursue a business combination with Parent, and ultimately the Board authorized
the executive officers of the Company to pursue the proposed business
combination with Parent. On October 22, 1998, the closing price of the Shares,
as reported on NASDAQ, was $2.1875 per Share.
 
  On October 23, 1998, Dr. Gat discussed the proposed transaction with Dr.
Betz. On November 3, 1998, Parent's U.S. legal counsel, delivered a draft term
sheet to the Company's legal counsel. The draft term sheet proposed that
Parent acquire the Company for cash consideration of $5.50 per Share subject
to the resolution of a number of diligence and business issues. From October
24 to November 19, 1998, representatives of the Company, Parent and their
respective investment bankers and legal counsel had numerous conversations and
meetings regarding due diligence and business issues with respect to the
proposed business combination, including the structure of the transaction and
the Company's agreements and arrangements with the Israeli Affiliate. Although
no letter of intent was signed, substantially all of the business issues
(other than the structure of the transaction and conditions to completing the
acquisition) were resolved at a meeting held on November 19, 1998, among Drs.
Gat and Betz, representatives of the Company's and Parent's respective legal
counsel and a representative of SoundView.
 
  On November 11 and 12, 1998, representatives of Parent visited the Israeli
Affiliate where management of the Israeli Affiliate gave a presentation and
conducted a plant visit.
 
  From November 16 to 20, 1998, representatives of Parent and its accountants,
legal counsel and investment bankers engaged in comprehensive due diligence at
the Company's offices in San Jose.
 
  On November 21, 1998, Parent's U.S. legal counsel distributed the first
draft of a merger agreement to the Company, Parent and their respective
investment bankers and legal counsel, which draft agreement provided for the
acquisition of the Company by Parent by way of a merger. On December 3, 1998,
Parent's U.S. legal counsel distributed another draft of the Merger Agreement
to the Company, Parent and their respective investment bankers and legal
counsel, which provided for the Offer, the Merger and other Transactions. The
terms of the Merger Agreement and related agreements, including the
transaction structure and conditions to completing the acquisition, were
negotiated during the period from November 21, 1998 to January 14, 1999.
 
  On November 25, 1998, to address market rumors and with the consent of
Parent, the Company issued a press release indicating that it was in
discussions with Parent concerning a possible cash acquisition of the Company.
At the time, the structure of the transaction and the conditions to completing
the acquisition had not been fully determined.
 
  On November 25, 1998, Drs. Gat and Betz, a representative of Clal
Electronics, representatives of the Israeli Affiliate, and an investor in the
Israeli Affiliate met in Essen, Germany. At the meeting, Parent and the
Israeli Affiliate agreed in principle to an arrangement pursuant to which,
concurrently with or immediately following the Merger, Parent would acquire
all of the outstanding capital stock of the Israeli Affiliate not owned by the
Company.
 
  At a meeting of the Board on December 2, 1998, a representative of the
Company's legal counsel described for the directors the general terms of the
proposed Merger Agreement, a copy of which had been provided to the directors
prior to the meeting. A representative of SoundView presented its analysis and
summary of the terms of the Offer, the Merger and other Transactions, and then
delivered its oral fairness opinion to the Company and informed the directors
that the consideration to be received by the shareholders of the Company
pursuant to the Merger Agreement is fair, from a financial point of view, to
the shareholders. The Board, with the assistance of the representatives of
SoundView and the Company's legal counsel, discussed the terms, benefits and
disadvantages of the proposed acquisition. Following such discussion, the
Board determined that the terms of the Merger Agreement, the Offer and the
Merger were fair to the Company's shareholders and that it was advisable and
in
 
                                      16
<PAGE>
 
the best interest of the shareholders for the Company to enter into such
transactions with Parent and for the Company's shareholders to tender their
Shares in the Offer. The Board authorized the Company's executive officers to
finalize, execute and deliver the Merger Agreement and any related agreements.
 
  On December 3, 1998, the Supervisory Board of STEAG met and approved the
general terms of the Merger Agreement and the Transactions, including the
Offer and the Merger.
 
  On January 5, 1999, SoundView confirmed its December 2, 1998 oral fairness
opinion and delivered to the Board its written opinion that, as of January 5,
1999, the consideration to be received by the shareholders of the Company
pursuant to the Merger Agreement is fair, from a financial point of view, to
such shareholders (the "Fairness Opinion").
 
  On January 18, 1999, the Company, Parent and Purchaser entered into the
Merger Agreement.
 
  Factors Considered by the Board; Reasons for the Merger. In approving the
Merger Agreement and the Transactions and recommending that the shareholders
of the Company tender their shares pursuant to the Offer, the Board considered
a number of factors, including:
 
  (i)the financial situation of the Company and its prospects of recovering
from the current recession in the semiconductor industry;
 
  (ii)the financial and other terms of the Merger Agreement and the
Transactions, including the provisions of the Merger Agreement allowing the
Company to respond to unsolicited written inquiries concerning an acquisition
of the Company, and the provisions which permit the Company to terminate the
Merger Agreement upon payment to Purchaser of a break-up fee in the event that
the Board determines that its fiduciary duties require it to withdraw its
recommendation that shareholders tender their Shares in the Offer;
 
  (iii)that the $5.50 Offer Price represents a premium of approximately 151%
over the closing price of the Shares on NASDAQ on October 22, 1998, the day
the Board first authorized the Company to pursue a business combination with
Parent;
 
  (iv)the presentation made to the Board by representatives of SoundView on
December 2, 1998, the oral opinion of SoundView that, as of such date, the
consideration to be received by the shareholders of the Company pursuant to
the Merger Agreement is fair, from a financial point of view, to such
shareholders, and the written Fairness Opinion;
 
  (v)the failure of the First Prospect, the Second Prospect and any other
potential bidders to submit a proposal having terms more favorable than the
terms proposed by Parent; and the view of the Board, based in part upon the
presentations of management to the Board on October 22, 1998, regarding the
unlikelihood of a superior offer arising;
 
  (vi)that alternative means of maximizing shareholder value and improving the
viability of the Company, such as raising additional capital through equity or
convertible debt, searching for a strategic partner to invest in the Company
or further reducing the Company's work force, would be less advantageous to
the Company's current shareholders than the Transactions will be;
 
  (vii)the Company's long-term and short-term capital needs;
 
  (viii)the history of the price of the Shares on NASDAQ over the last 18
months;
 
  (ix)the likelihood that the Transactions will be consummated, including the
fact that Parent's and Purchaser's obligations under the Offer are not subject
to any financing conditions;
 
  (x)Parent's financial condition and ability to cause Purchaser to meet its
obligations under the Merger Agreement;
 
  (xi)legal matters relating to the Transactions, including the review
provided for under the HSR Act with respect to the antitrust implications of
the Offer and the terms of the Offer and the Merger Agreement; and
 
  (xii)the willingness of certain shareholders of the Company to enter into
the Voting Agreements, pursuant to which, among other things, such
shareholders agreed to tender the Shares owned by them into the Offer.

  The foregoing discussion of the information and factors considered and given
weight by the Board is not intended to be exhaustive. In view of the variety
of factors considered in connection with its evaluation of the Merger
Agreement and the Offer, the Board did not find it practicable to, and did
not, quantify or otherwise assign relative weights to the specific factors
considered in reaching its determination. In addition, individual members of
the Board may have given different weights to different factors.
 
  The full text of SoundView's Fairness Opinion is incorporated by reference
herein and is attached as Appendix A to this Schedule 14D-9. The Fairness
Opinion does not constitute a recommendation of the Transactions over any
other alternative transactions which may be available to the Company and does
not address the underlying business decision of the Board to proceed with or
effect the Transactions. Shareholders are urged to read the Fairness Opinion
in its entirety, including the matters reviewed and considered, assumptions
made, limitations on and scope of the analyses by SoundView in arriving at its
opinion.
 
Item 5. Persons Retained, Employed or to be Compensated.
 
  Pursuant to a letter agreement, dated as of June 25, 1998, the Company
retained SoundView as its financial advisor in connection with the Offer and
the Merger. The Company has agreed to pay SoundView a transaction fee, if the
Transactions are consummated, based on (i) the aggregate consideration paid in
the Offer and the Merger to the shareholders of the Company, and (ii) the
amount of debt of the Company as of the closing of the Merger. Based on an
Offer Price of $5.50 per Share, the Company anticipates that SoundView will
receive a transaction fee of approximately $625,000. The Company has paid
$75,000 to SoundView in connection with its preparation of the Fairness
Opinion, which amount will be credited against the transaction fee if the
Transactions are consummated.
 
  The Company has agreed to reimburse SoundView for certain of its out-of-
pocket and incidental expenses, and has made an advance payment of $25,000 to
SoundView for such expenses. The Company also has agreed to indemnify
SoundView and certain related persons against certain liabilities in
connection with its engagement, including certain liabilities under the
federal securities laws.
 
  Except as set forth above, neither the Company nor any person acting on its
behalf has or currently intends to employ, retain, or compensate any person to
make solicitations or recommendations to the shareholders of the Company with
respect to the Offer and the Merger.
 
Item 6. Recent Transactions and Intent With Respect to Securities.
 
  (a) During the past sixty (60) days, no transactions in the Shares have been
effected by the Company or by any executive officer, director, affiliate or
subsidiary of the Company.
 
  (b) To the knowledge of the Company, all of the Company's executive
officers, directors and affiliates who own Shares presently intend to tender
to Purchaser pursuant to the Offer all of the Shares which are held of record
or beneficially owned by such persons.
 
Item 7. Certain Negotiations and Transactions by the Subject Company.
 
  (a) Except as set forth in this Schedule 14D-9, no negotiation is being
undertaken or is underway by the Company in response to the Offer which
relates to or would result in (1) an extraordinary transaction such as a
merger or reorganization, involving the Company or any subsidiary of the
Company, (2) a purchase, sale or transfer of a material amount of assets by
the Company or any subsidiary of the Company, (3) a tender offer for or other
acquisition of securities by or of the Company, or (4) any material change in
the present capitalization or dividend policy of the Company.
 
  (b) Except as set forth in this Schedule 14D-9, there are no transactions,
resolutions of the Board, agreements in principle or signed contracts in
response to the Offer that relate to or would result in one or more of the
matters referred to in Item 7(a)(1), (2), (3) or (4), above.
 
                                      18
<PAGE>
 
Item 8. Additional Information to be Furnished.
 
  If the Stock Option is exercised by Purchaser (resulting in Purchaser
acquiring 90% or more of the outstanding Shares), Parent will be able to
effect a short-form merger under the CGCL, subject to the terms and conditions
of the Merger Agreement.
 
  In the event that more than 50% of the Shares then outstanding are tendered
pursuant to the Offer and not withdrawn, but less than 90% of the Shares then
outstanding are acquired by Purchaser pursuant to the Offer and the Stock
Option, Purchaser will reduce the number of Shares subject to the Offer to the
Revised Minimum Number and, if a greater number of Shares is tendered into the
Offer and not withdrawn, Purchaser will purchase, on a pro rata basis, the
Revised Minimum Number of Shares (it being understood that Purchaser will not
in any event be required to accept for payment, or pay for, any Shares if less
than the Revised Minimum Number of Shares are tendered pursuant to the Offer
and not withdrawn by the Expiration Date).
 
  In such event, Purchaser would own upon consummation of the Offer 49.9% of
the Shares then outstanding and would thereafter solicit the approval of the
Merger Agreement by a vote of the shareholders of the Company. Under such
circumstances, a significantly longer period of time would be required to
effect the Merger.

                    TEXT OF THE SOUNDVIEW FAIRNESS OPINION
 
January 5, 1999
 
Board of Directors
AG Associates, Inc.
4425 Fortran Drive
San Jose, CA 95134
 
Ladies and Gentlemen:
 
  We understand that AG Associates, Inc. ("AG" or the "Company") is
considering entering into a merger agreement (the "Merger Agreement") whereby
STEAG will acquire all of the outstanding common stock of the Company. In
aggregate, the consideration to be paid for the Company will be approximately
$41.2 million, (the "Consideration"), consisting of $5.50 per share in cash
plus the assumption of approximately $7.1 million in net indebtedness. The
terms and conditions of the transaction (the "Proposed Transaction") are set
forth in more detail in the draft merger agreement (the "Draft Merger
Agreement") dated December 23, 1998, which has been furnished to us.
 
  We have been asked by the Board of Directors of the Company to render our
opinion as to whether the Consideration pursuant to the Draft Merger Agreement
is fair, from a financial point of view, to the Company's shareholders.
 
  In conducting our analysis and arriving at our opinion as expressed herein,
we have reviewed and analyzed, among other things, the following:
 
  (i)   the Draft Merger Agreement dated December 23, 1998 and the specific
        terms of the Proposed Transaction;
 
  (ii)  AG's financial and operating information for the three years ended
        September 30, 1998;
 
  (iii) certain financial and operating information regarding the business,
        operations and prospects of AG, including forecasts and projections,
        provided to us by the management of the Company;
 
  (iv)  a comparison of the historical and projected financial results and
        financial condition of AG with those of other companies and businesses
        that we deemed relevant; and
 
  (v)   a comparison of the financial terms of the Proposed Transaction with
        the financial terms of certain other selected transactions that we
        deemed relevant.
 
  In addition, in arriving at our opinion, we have held discussions with AG's
and STEAG's managements concerning their businesses, operations, assets,
financial conditions and prospects. We also undertook such other studies,
analyses and investigations, as we deemed appropriate.
 
  In arriving at our opinion, we have not made, obtained or assumed any
responsibility for any independent evaluation or appraisal of the properties
and facilities or of the assets and liabilities (contingent or otherwise) of
the Company. We have assumed and relied upon the accuracy and completeness of
the financial and other information supplied to or otherwise used by us in
arriving at our opinion and have not attempted independently to verify, or
undertaken any obligation to verify, such information. We have further relied
upon the assurances of the management of AG and STEAG that they were not aware
of any facts that would make such information inaccurate or misleading. In
addition, we have assumed that the forecasts and projections provided to
SoundView Technology Group, Inc. by the Company represent the best currently
available estimates and judgment of the Company's management as to the future
financial condition and results of operations of the Company, and have
 
                                      A-1
<PAGE>
 
assumed that such forecasts and projections have been reasonably prepared
based on such currently available estimates and judgments. We assume no
responsibility for and express no view as to such forecasts and projections or
the assumptions on which they are based.
 
  We have also taken into account our assessment of general economic, market
and financial conditions and our experience in similar transactions, as well
as our experience in securities valuation in general. Our opinion is
necessarily based upon conditions as they exist and can be evaluated on the
date hereof.
 
  We do not express any view as to what the value of the Company's stock will
be upon completion of the Proposed Transaction, or the price at which the
Company's stock will trade prior to the closing of the Proposed Transaction.
This letter is for the benefit and use of the Board of Directors of the
Company in its consideration of the Proposed Transaction. This letter does not
constitute a recommendation of the Proposed Transaction over any other
alternative transactions which may be available to the Company and does not

Dear Shareholders:
 
   On behalf of the Board of Directors of AG Associates, Inc., I am pleased to
inform you that on January 18, 1999, AG Associates entered into a definitive
agreement with STEAG Electronic Systems GmbH, located in Essen, Germany
("STEAG"), and a wholly owned subsidiary of STEAG, MIG Acquisition Corporation
("Purchaser"). The definitive agreement (the "Merger Agreement") provides for
the acquisition of AG Associates by STEAG through Purchaser. Purchaser has
commenced today a cash tender offer to purchase all of the outstanding shares
of AG Associates' common stock, at $5.50 per share, in cash, without interest
(the "Offer"). An Offer to Purchase, dated January 22, 1999, and other
materials relating to the Offer are enclosed with this letter.
 
   Following the successful completion of the Offer, upon approval by a
shareholder vote, if required, Purchaser will be merged with and into AG
Associates (the "Merger") and AG Associates will become a wholly owned
subsidiary of STEAG. If you do not tender your shares in the Offer, upon
completion of the Merger, you will receive $5.50, in cash, without interest,
for each share of common stock you then hold, unless you are entitled to and
properly exercise dissenters' rights with respect to the Merger.
 
   YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED THAT THE OFFER AND MERGER
ARE FAIR TO AND IN THE BEST INTERESTS OF THE SHAREHOLDERS OF AG ASSOCIATES AND
IS RECOMMENDING THAT THE SHAREHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES
IN THE OFFER.
 
   In arriving at its recommendation, the Board of Directors gave careful
consideration to a number of factors. These factors included the opinion of
SoundView Technology Group, Inc. that, as of January 5, 1999, the consideration
to be received by the shareholders in the Offer and Merger is fair, from a
financial point of view, to the shareholders. The factors considered by the
Board of Directors, including current market conditions, are described
beginning on page 17 in the Solicitation/Recommendation Statement on
Schedule 14D-9, which is enclosed with this letter. The text of the fairness
opinion is included in Appendix A to the Schedule 14D-9.
 
   The enclosed Offer to Purchase, dated January 22, 1999, and related
materials, including a Letter of Transmittal to be used to tender your shares
to the Purchaser, state the terms and conditions of the Offer and the Merger
and provide instructions as to how to tender your shares. I urge you to read
these materials carefully and, if you concur with the Board's recommendation,
tender your shares to Purchaser.
 
   If you have any questions as to this transaction, please call me at 408-935-
2001, or our CFO, Mr. Kirk Johnson, at 408-935-2004.
 
                                          Sincerely,
 
                                          /s/ ARNON GAT

DIRECTORS' COMPENSATION
 
  Directors do not receive cash compensation for serving as members of the
Company's Board of Directors, but are reimbursed for their expenses in
attending meetings of the Board and of Committees of the Board. Outside
Directors (directors who are not employed by the Company or any of its
subsidiaries and who do not represent a corporate strategic partner of the
Company) are eligible for automatic option grants under the 1994 Directors
Stock Option Plan (the "Directors Plan"). The Directors Plan provides for the
automatic grant of an option for 5,000 shares when an individual first becomes
an Outside Director. If the individual is still an Outside Director on each
anniversary of the date he or she joined the Board, he or she is automatically
granted an additional option for 1,000 shares. All options granted under the
Directors Plan have an exercise price equal to the fair market value of the
Company's common stock on the date of grant, become exercisable at a rate of
25% of the shares each year, and expire five years after the date of grant.
During fiscal 1997, the following options were granted under the Directors
Plan to Outside Directors of the Company: in January 1997, the Company granted
an option to purchase 1,000 shares of Common Stock to Cecil Parker, and in
February 1997, the Company granted an option to purchase 1,000 shares of
Common Stock to John Moore. Mr. Moore resigned from the Board in November
1997. All other options currently held by directors were granted prior to the
time the Directors Plan was adopted.
 
  The following options were held by the Company's directors as of September
30, 1997:

(1) Options granted in fiscal 1997 vest at the rate of 25% of the shares
    subject to the option annually from the date of grant. The exercise price
    was equal to the fair market value of the Common Stock on the date of
    grant. Under the terms of the option plan, the Compensation Committee
    retains discretion, subject to plan limits, to modify the terms of
    outstanding options.
(2) Percent of total options granted to employees in fiscal year is based on a
    total of 357,680 options granted to employees during fiscal 1997.
(3) In accordance with the rules of the Securities and Exchange Commission
    (the "Commission"), the table sets forth the hypothetical gains or "option
    spreads" that would exist for the options at the end of their respective
    terms. These gains are based on assumed rates of annual compound stock
    price appreciation of 5% and 10% from the date the option was granted to
    the end of the option term. The 5% and 10% assumed annual compound rates
    of stock price appreciation are mandated by the rules of the Commission
    and do not represent the Company's estimate or projection of future Common
    Stock prices. Actual gains, if any, on option exercises are dependent on
    the future performance of the Company's Common Stock.
(4) Mr. McCallister resigned from the Company in December 1997.
 
  The following table sets forth the number of shares of Common Stock
represented by outstanding stock options held by each of the Named Officers as

Officers exercised stock options during fiscal 1997.

EMPLOYMENT AGREEMENTS
 
  The Company has entered into an employment agreement with Mr. Guardado,
dated July 20, 1995, which specifies that he will be paid a base salary of
$14,585 per month (calculating to $175,000 annually) and will be eligible for
a bonus of up to 45% of annual base salary based on the Company meeting
performance goals to be agreed upon by Mr. Guardado with the Company's Chief
Executive Officer prior to the beginning of each fiscal year. In addition,
pursuant to the agreement, the Company has reimbursed Mr. Guardado $30,000 for
his actual and reasonable expenses to relocate to the San Jose area. The
Company and Mr. Guardado must each give the other six months' notice of
termination of Mr. Guardado's employment. In addition to other fringe benefits
offered to the Company's employees generally and pursuant to the terms of Mr.
Guardado's employment agreement, in July 1995, Mr. Guardado was granted an
option to purchase up to 100,000 shares of the Company's Common Stock under
the 1993 Plan exercisable at $21.63 per share. In June 1996, this option grant
was repriced and is now exercisable at $7.125 per share. In connection with
Mr. Guardado's employment agreement, in August 1995, the Company advanced Mr.
Guardado $60,000 pursuant to a promissory note that bears interest at the rate
of 8.75% per annum. During fiscal 1996, Mr. Guardado paid down the note, and
the note had a remaining balance of $25,655 plus accrued interest of $2,085 as
of July 1997. In fiscal 1997, the Company extended the note until July 1998
and added a provision to the note specifying that all payments and interest
due on the note would be canceled if Mr. Guardado is employed by the Company
through July 1998.
 
  In fiscal 1997, the executive officers of the Company each entered into an
employment agreement with the Company that provides for one year of salary
continuation and up to two years of option vesting following the closing of
certain change of control transactions.
 
                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
  See "Proposal No. 1--Election of Directors" above for a description of
directors' compensation arrangements and "Executive Compensation--Employment
Agreements" above for a description of compensation-related agreements entered
into by the Company with its officers.
 
  Other than these compensation arrangements, since October 1, 1996, there has
not been, nor is there currently proposed, any transaction or series of
transactions to which the Company was or is to be a party in which the amount
involved exceeds $60,000 and in which any director, executive officer, or
holder of more than 5% of the Company's Common Stock had or will have a direct
or indirect material interest except for the transactions described below.
 
CANON SALES CO., INC. ("CANON")
 
  In July 1989, Canon, Appex Corporation and Nippon Typewriter Corporation
(collectively, the "Purchasers") entered into Stock Purchase Agreements with
the Company. Under the Stock Purchase Agreements, the Purchasers acquired
approximately 799,999 shares of the Common Stock of the Company, or 37% of the
then-outstanding shares of the Company's Common and Preferred Stock for an
aggregate purchase price of approximately $3.8 million. In connection with
such purchase, the Purchasers were granted incidental registration rights at
the Purchasers' expense to include their shares in any registration of shares
held by shareholders in an amount up to 37% of the shares registered.
Subsequent to the purchase, Norio Kuroda's predecessor, who was then Managing
Director of Canon, was elected to the Company's Board of Directors.
Mr. Kuroda, Managing Director of Canon's Optical Product Group, now serves on
the Company's Board of Directors, although there is no obligation on the
Company's part to nominate a representative of Canon.
 
  In January 1994, the Company entered into an Improvements License Agreement
with Canon under which the Company granted Canon a non-exclusive, non-
transferable (except in a merger or sale of assets), royalty-free, fully paid
license to use the Company's technology (a) to make modifications to rapid
thermal processing ("RTP") systems purchased from the Company and to
distribute such modified units in Japan under any separate distribution
arrangement that may exist between the Company and Canon from time to time and
(b) to
 
                                       4

manufacture prototypes of component parts of RTP systems but only if such
parts are integrated into a system purchased from the Company. Title to the
resulting modifications is held jointly by Canon and the Company without the
right to sell or transfer rights in the same.
 
  In connection with the 1989 transactions described above, Canon entered into
an agreement (renewed in 1994) to act as the Company's exclusive distributor
in Japan. Sales to Canon amounted to $5.7 million under this arrangement in
fiscal 1997.
 
AGREEMENTS WITH CLAL ELECTRONICS
 
  Pursuant to a 1995 agreement among the Company, Dr. Arnon Gat, the Company's
Chairman of the Board, a director and a principal shareholder of the Company,
Anita Gat, an executive officer, director and principal shareholder of the
Company, AG Associates (Israel) Ltd, then a 49%-owned subsidiary of the
Company ("AG Israel"), Rapro Technology Inc., a wholly owned subsidiary of the
Company ("Rapro"), and Clal Electronics, Clal Electronics acquired
approximately 544,000 shares (then 9.9%) of the Company's outstanding shares
of Common Stock from existing shareholders. After May 15, 1998, Clal
Electronics may increase its ownership in the Company up to 12% and, if its
ownership exceeds 10%, it has the right to nominate a member for election to
the Company's Board of Directors. In the interim, Clal Electronics has the
right to nominate an observer to attend meetings of the Company's Board of
Directors.
 
  Clal Electronics and its assignees have also been granted the right to
require the Company to register the shares of the Company's Common Stock sold
in 1995 to Clal Electronics with the Securities and Exchange Commission and to
include such shares in any registration planned by the Company. These
registration rights were granted in order to enable the holder of the shares
to sell such shares in the public market and are exercisable at the expense of
the holders of the shares to be registered.
 
AGREEMENTS BETWEEN AG ISRAEL AND THE COMPANY
 
  In March 1996, the Company and AGI, Inc., the wholly owned subsidiary of AG
Israel, entered into a Transition Services Agreement whereby the Company
provides certain services to AGI, Inc. These services include: (1) providing
employment, operational and human resources services under the direction of
AGI, Inc., utilizing, in all cases, records and procedures separate from those
of the Company; (2) providing accounts payable services to AGI, Inc., and, at
the request of AGI, Inc., collecting accounts receivable and paying accounts
payable for AGI, Inc.; and (3) providing such other services as shall be
agreed to by the parties. As consideration for these services, AGI, Inc. pays
to the Company the incremental direct costs and out-of-pocket expenses derived
directly from the provision of the services. During fiscal 1997, AGI, Inc.
incurred expenses payable to the Company of $548,750 under the Transition
Services Agreement. The Transition Services Agreement has an indefinite term,
but either party may cancel any or all service or services provided pursuant
to the Transition Services Agreement on 90-days prior notice. As of December
31, 1997, all of the expenses due under the Transition Services Agreement at
the end of fiscal 1997 had been paid by AG Israel.
 
  The Company also subleases to AGI, Inc. 3,148 square feet of space that is
part of the Company's principal executive office facility. The rental charge
is $7,500 per month under the terms of a Sublease, dated, for reference
purposes only, August 20, 1996, among the Company, AGI, Inc. and AG Israel as
guarantor of AGI, Inc.'s obligations. The Sublease terminates on November 30,
1998, unless sooner terminated as provided in the Sublease, except that AGI,
Inc. has the option through October 2001 to extend and renew the Sublease upon
the same terms and conditions and at the same rental rate (as such may be
adjusted) for consecutive one year additional terms. During fiscal 1997, AGI,
Inc. incurred expenses payable to the Company of $440,000 under the Sublease.
As of December 31, 1997, all of the expenses due under the Sublease at the end
of fiscal 1997 had been paid by AG Israel. In addition, the Company and AGI,
Inc. agreed to share the cost of a research and development laboratory, and,
in connection with this agreement, AGI, Inc. incurred expenses payable to the
Company of $350,000 in fiscal 1997. As of December 31, 1997, all of the
expenses due under this research and development laboratory sharing agreement
at the end of fiscal 1997 had been paid by AG Israel.
 
                                       5

  In January 1997, the Company and AG Israel entered into a Technology
Agreement whereby the Company granted to AG Israel a license to use new
technology generated under the Company's next generation rapid thermal
processing research and development program in return for AG Israel's
obligation to pay the Company up to $2 million in royalties on AG Israel's
sale of products incorporating certain of the Company's technology. No
royalties were due under this Technology Agreement in fiscal 1997.
 
  During fiscal 1997, AG Israel completed a private placement of its ordinary
shares in which the Company did not participate, reducing the Company fully
diluted equity interest in AG Israel from approximately 45% to 25.2% and the
Company's voting interest in AG Israel from 49% to 28%. At that time, the
Company, Clal Electronics and AG Israel also modified certain additional
existing agreements as follows:
 
  (1) Fields of Use. During 1995 and until May 15, 2002, AG Israel and the
      Company had agreed to operate to the exclusion of the other in a
      defined "Field of Use." The Fields of Use for each of AG Israel and the
      Company were clarified during fiscal 1997 to make certain that both
      parties would be allowed to compete in certain chemical vapor
      deposition applications and that both parties could develop technology
      involving certain integrated circuit manufacturing processes. The
      effect of this clarification was to reduce the scope of both the
      Company's and AG Israel's exclusive Fields of Use and increase the
      number of markets and applications, including certain cluster tool
      applications, in which the Company and AG Israel can compete.
 
  (2) Options on AG Israel Stock. A five-year option held by the Company to
      purchase the Clal Electronics' ownership interest in AG Israel at a
      specified price, and a right of the Company to require the sale of such
      interest to the Company if AG Israel should become inactive, were each
      terminated.
 
  (3) AG Israel Corporate Governance. Certain 1995 agreements between Clal
      Electronics and the Company concerning the management, board
      representation and obligations to continue to fund AG Israel were
      terminated. In connection with AG Israel's 1997 closing of its new
      round of financing, Clal Electronics and AG Associates entered into an
      agreement with the new AG Israel investors concerning the corporate
      governance of AG Israel, replacing the 1995 corporate governance
      agreements. Under the new agreement, the Company is entitled to appoint
      up to two directors of AG Israel until its initial public offering. Dr.
      Gat serves as one of the directors.
 
  (4) AG Israel Indemnities. During 1995, at the time Clal Electronics
      invested in AG Israel, the Company, Dr. Gat, and Rapro made certain
      warranties to, and promised to indemnify, AG Israel and Clal
      Electronics with respect to the status and condition of the technology
      that is currently jointly owned by AG Israel and the Company. During
      1997, these warranties and indemnities were amended to release Dr. Gat
      from any obligation thereunder and to remove Clal Electronics as a
      beneficiary thereof, leaving the Company as the sole obligor thereunder
      and AG Israel as the sole beneficiary.
