        This Current Report on Form 8-K contains forward looking statements that
involve risks and uncertainties relating to the acquisition by Asyst
Technologies, Inc., a California corporation ("Asyst"), of Progressive System
Technologies, Inc., a Texas corporation ("PSTI") and the private placement of
625,000 shares of Asyst common stock. Actual results and developments may differ
materially from those described in this Current Report. For more information
about Asyst and risks relating to investing in Asyst, refer to Asyst's most
recent reports on Form 10-Q and Form 10-K.

Item 2. Acquisition or Disposition of Assets.

       On June 3, 1999, Asyst completed the acquisition of PSTI by merging PSTI
Merger Sub Acquisition Corp. ("Merger Sub") with and into PSTI with PSTI
surviving as the wholly owned subsidiary of Asyst. The acquisition was
accomplished pursuant to an Agreement and Plan of Merger and Reorganization,
dated as of June 2, 1999 (the "Reorganization Agreement") among Asyst, Merger
Sub, PSTI, Advent International Investor II, Envirotech Fund I and Global
Private Equity II. In connection with the acquisition, certain debt holders,
option holders and holders of PSTI capital stock outstanding on June 3, 1999
received shares of Asyst common stock. The purchase price was arrived at through
arms-length negotiations. The total number of shares of Asyst common stock
issued in connection with the acquisition was 500,000 shares. In addition to the
payment of shares of Asyst common stock, Asyst assumed certain outstanding
options to purchase PSTI common stock, which were converted into options to
purchase up to approximately 5,500 Asyst shares with exercise prices
significantly above Asyst's current price, and Asyst assumed and repaid PSTI's
bank debt of approximately $1.23 million. The acquisition will be accounted for
as a pooling of interests.

       PSTI is a supplier of substrate management systems for open-cassette,
SMIF-integrated wafer logistics and reticle automation. Asyst currently intends
to maintain PSTI as a wholly-owned subsidiary and to have PSTI continue to
conduct its business as historically conducted.

      A copy of the press release announcing the signing of the Letter of Intent
is attached hereto as Exhibit 99.1 and incorporated by reference herein. A copy
of the press release announcing the consummation of the acquisition is attached
hereto as Exhibit 99.2 and incorporated by reference herein.

Item 5. Other Events.

       On May 26, 1999, Asyst completed the private placement of 625,000 shares
of Asyst common stock to eight institutional investors. The private placement
was accomplished pursuant to a Common Stock Purchase Agreement, dated as of May
26, 1999, among Asyst and the purchasers thereto. The private placement was
priced at $18.00 per share, for aggregate proceeds to Asyst of approximately
$11.3 million. The purpose of the private placement was to untaint shares of
Asyst common stock to obtain pooling of interests accounting treatment for the
acquisition of PSTI. The proceeds will be used for general corporate purposes.

       A copy of the press release announcing the consummation of the private
placement is attached hereto as Exhibit 99.2 and incorporated by reference
herein.

                                   RECITALS

     the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
     amended (the "Code").  For accounting purposes, it is intended that the
     Merger be treated as a "pooling of interests."

  C. This Agreement has been approved by the respective boards of directors of
     Parent, Merger Sub, the Company and the Signing Shareholder.

                                   AGREEMENT

separate existence of Merger Sub shall cease. The Company will continue as the
surviving corporation in the Merger (the "Surviving Corporation").

this Agreement and in the applicable provisions of the Texas Business
Corporation Act.

     1.4  Payment of Proceeds.

          (a)  Subject to Sections 1.9(c) and 1.10, at the Closing Date, by
virtue of the Merger and without any further action on the part of Parent,

     1.6 Employee Stock Options. At the Closing Date, each stock option that is
then outstanding under the Company's 1995 Stock Option/Issuance Plan or any
other plan, whether vested or unvested (a "Company Option"), shall be assumed by
Parent in accordance with the terms (as in effect as of the date of this
Agreement) of the Company's 1995 Stock Option/Issuance Plan or any other plan,
whether vested or unvested (a "Company Option"), shall be assumed by Parent in
accordance with the terms (as in effect as of the date of this Agreement) of the
Company's 1995 Stock Option/Issuance Plan or any other plan and the stock option
agreement by which such Company Option is evidenced. All rights with respect to
Company Common Stock under outstanding Company Options shall thereupon be
converted into rights with respect to Parent Common Stock. Accordingly, from and
after the Closing Date, (a) each Company Option assumed by Parent may be
exercised solely for shares Parent Common Stock, (b) the number of shares of
Parent Common Stock subject to each such assumed Company Option shall be as set
forth on the attached Schedule 1.6, (c) the per share exercise price for the
Parent Common Stock issuable upon exercise of each such assumed Company Option
shall be as set forth on the attached Schedule 1.6, and (d) all restrictions on
the exercise of each such assumed Company Option shall continue in full force
and effect, and the term, exercisability, vesting schedule and other provisions
of such Company Option shall otherwise remain unchanged; provided, however, that
each such assumed Company Option shall, in accordance with its terms, be subject
to further adjustment as appropriate to reflect any stock split, reverse stock
split, stock dividend, recapitalization or other similar transaction effected by
Parent after the Closing Date.

     1.7  Closing of the Company's Transfer Books.  At the Closing Date,
holders of certificates representing shares of the Company's capital stock that
were outstanding immediately prior to the Closing Date shall cease to have any
rights as shareholders of the Company, and the stock transfer books of the
Company shall be closed with respect to all shares of such capital stock
outstanding immediately prior to the Closing Date. No further transfer of any
such shares of the Company's capital stock shall be made on such stock transfer
books after the Closing Date. If, after the Closing Date, a valid certificate
previously representing any of such shares of the Company's capital stock (a
"Company Stock Certificate") is presented to the Surviving Corporation or
Parent, such Company Stock Certificate shall be canceled and shall be exchanged
as provided in Section 1.8.

     1.8  Exchange of Certificates.

          (a) At or as soon as practicable after the Closing Date, Parent will
send to the holders of Company Stock Certificates (i) a letter of transmittal in
customary form and containing such provisions as Parent may reasonably specify,
and (ii) instructions for use in effecting the surrender of Company Stock
Certificates in exchange for certificates representing Parent Common Stock. Upon
surrender of a Company Stock Certificate to Parent for exchange, together with a
duly executed letter of transmittal and such other documents as may be
reasonably required by Parent, the holder of such Company Stock Certificate
shall be entitled to receive in exchange therefor a certificate representing the
number of whole shares of Parent Common Stock that such holder has the right to
receive pursuant to the provisions of this Section 1, and the Company Stock
Certificate so surrendered shall be canceled. Until surrendered as contemplated
by this Section 1.8, each Company Stock Certificate shall be deemed, from and
after the Closing Date, to represent only the right to receive upon such
surrender a certificate representing shares of Parent Common Stock (and cash in
lieu of any fractional share of Parent Common Stock) as contemplated by this
Section 1. If any Company Stock Certificate shall have been lost, stolen or
destroyed, Parent may, in its discretion and as a condition precedent to the

                                       3
<PAGE>

issuance of any certificate representing Parent Common Stock, require the owner
of such lost, stolen or destroyed Company Stock Certificate to provide an
appropriate affidavit and to deliver a bond (in such sum as Parent may
reasonably direct) as indemnity against any claim that may be made against
Parent or the Surviving Corporation with respect to such Company Stock
Certificate.

          (b) No dividends or other distributions declared or made with
respect to Parent Common Stock with a record date after the Closing Date shall
be paid to the holder of any unsurrendered Company Stock Certificate with
respect to the shares of Parent Common Stock represented thereby, and no cash
payment in lieu of any fractional share shall be paid to any such holder, until
such holder surrenders such Company Stock Certificate in accordance with this
Section 1.9 (at which time such holder shall be entitled to receive all such
dividends and distributions and such cash payment).

          (c) No fractional shares of Parent Common Stock shall be issued in
connection with the Merger, and no certificates for any such fractional shares
shall be issued. In lieu of such fractional shares, any holder of capital stock
of the Company who would otherwise be entitled to receive a fraction of a share
of Parent Common Stock (after aggregating all fractional shares of Parent Common
Stock issuable to such holder) shall, upon surrender of such holder's Company
Stock Certificate(s), be paid in cash the dollar amount (rounded to the nearest
whole cent), without interest, such fraction.

          (d) Parent and the Surviving Corporation shall be entitled to deduct
and withhold from any consideration payable or otherwise deliverable to any
holder or former holder of capital stock of the Company pursuant to this
Agreement such amounts as Parent or the Surviving Corporation may be required to
deduct or withhold therefrom under the Code or under any provision of state,
local or foreign tax law. To the extent such amounts are so deducted or
withheld, such amounts shall be treated for all purposes under this Agreement as
having been paid to the Person to whom such amounts would otherwise have been
paid.

          (e) Neither Parent nor the Surviving Corporation shall be liable to
any holder or former holder of capital stock of the Company for any shares of
Parent Common Stock (or dividends or distributions with respect thereto), or for
any cash amounts, delivered to any public official pursuant to any applicable
abandoned property, escheat or similar law.

     1.9  Dissenting Shares.

          (a) Notwithstanding anything to the contrary contained in this
Agreement, any shares of capital stock of the Company that, as of the Closing
Date, are or may become "dissenting shares" within the meaning of Texas Business
Corporation Act shall not be converted into or represent the right to receive
Parent Common Stock in accordance with Section 1.4 (or cash in lieu of
fractional shares in accordance with Section 1.8(c)), and the holder or holders
of such shares shall be entitled only to such rights as may be granted to such
holder or holders in Texas Business Corporation Act; provided, however, that if
the status of any such shares as "dissenting shares" shall not be perfected, or
if any such shares shall lose their status as "dissenting shares," then, as of
the later of the Closing Date or the time of the failure to perfect such status
or the loss of such status, such shares shall automatically be converted into
and shall represent only the right to receive (upon the surrender of the
certificate or certificates

                                       4
<PAGE>

representing such shares) Parent Common Stock in accordance with Section 1.4
(and cash in lieu of fractional shares in accordance with Section 1.8(c)).

          (b) The Company shall give Parent (i) prompt notice of any written
demand received by the Company prior to the Closing Date to require the Company
to purchase shares of capital stock of the Company pursuant to Texas Business
Corporation Act and of any other demand, notice or instrument delivered to the
Company prior to the Closing Date pursuant to the Texas Business Corporation
Act, and (ii) the opportunity to participate in all negotiations and proceedings
with respect to any such demand, notice or instrument. The Company shall not
make any payment or settlement offer prior to the Closing Date with respect to
any such demand unless Parent shall have consented in writing to such payment or
settlement offer.

     1.10  Articles of Incorporation and Bylaws; Directors and Officers.
Unless otherwise determined by Parent and the Company prior to the Closing Date:

          (a) the Articles of Incorporation of the Surviving Corporation shall
be the Articles of Incorporation of the Merger Sub except as amended by the
Certificate of Merger filed with the Texas Secretary of State;

          (b) the Bylaws of the Surviving Corporation shall be amended and
restated as of the Closing Date to conform to the Bylaws of Merger Sub as in
effect immediately prior to the Closing Date; and

          (c) the directors and officers of the Surviving Corporation
immediately after the Closing Date shall be the current directors and officers
of the Merger Sub.

     1.11 Tax Consequences.  For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368 of the
Code. The parties to this Agreement hereby adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.

     1.12 Accounting Treatment. For accounting purposes, the Merger is intended
to be treated as a "pooling of interests."

     1.13 Further Action. If, at any time after the Closing Date, any further
action is determined by Parent to be necessary or desirable to carry out the
purposes of this Agreement or to vest the Surviving Corporation or Parent with
full right, title and possession of and to all rights and property of Merger Sub
and the Company, the officers and directors of the Surviving Corporation and
Parent shall be fully authorized (in the name of Merger Sub, in the name of the
Company and otherwise) to take such action.

Parent and Merger Sub are required to comply with or to perform at or prior to
the Closing shall have been complied with and performed in all respects.

     7.3 Legal Opinions. A legal opinion of Cooley Godward LLP, dated as of the
Closing Date, in the form of Exhibit H; and

     7.4 No Restraints. No temporary restraining order, preliminary or permanent
injunction or other order preventing the consummation of the Merger shall have
been issued by any court of competent jurisdiction and remain in effect, and
there shall not be any Legal Requirement enacted or deemed applicable to the
Merger that makes consummation of the Merger illegal.

forth in this Agreement);

          (b) by the Company if the Company reasonably determines that the

forth in this Agreement or in any other agreement or instrument delivered to

          (c) by Parent if the Closing has not taken place on or before June 30,
1999 (other than as a result of any failure on the part of Parent to comply with
or perform any covenant or obligation of Parent set forth in this Agreement);

          (d) by the Company if the Closing has not taken place on or before
June 30, 1999 (other than as a result of the failure on the part of the Company

SECTION 9.   INDEMNIFICATION, ETC.

     9.1  Survival of Representations, Etc.

          (a) The representations and warranties made by the Company and the
Signing Shareholder (including the representations and warranties set forth in
Section 2 and the representations and warranties set forth in the Closing
Certificates) shall survive the Closing and shall expire on the nine (9) month
anniversary of the Closing Date; provided, however, that if, at any time prior
to the nine (9) month anniversary of the Closing Date, any Indemnitee (acting in
good faith) delivers to the Indemnitors and the Escrow Agent a written notice
alleging the existence of an inaccuracy in or a breach of any of the
representations and warranties made by the Company (and setting forth in
reasonable detail the basis for such Indemnitee's belief that such an inaccuracy
or breach may exist) and asserting a claim for recovery under Section 9.2 based
on such alleged inaccuracy or breach, then the claim asserted in such notice
shall survive the nine (9) month anniversary of the Closing until such time as
such claim is fully and finally resolved. All representations and warranties
made by Parent and Merger Sub shall terminate and expire as of the nine (9)
month anniversary of the Closing Date, and any liability of Parent or Merger Sub
with respect to such representations and warranties shall thereupon cease.

          (b) The representations, warranties, covenants and obligations of the
Company and the Signing Shareholder, and the rights and remedies that may be
exercised by the Indemnitees, shall not be limited or otherwise affected by or
as a result of any information furnished to, or any investigation made by or
knowledge of, any of the Indemnitees or any of their Representatives, unless
such information is included in the Disclosure Schedule.

          (c) For purposes of this Agreement, each statement or other item of
information set forth in the Disclosure Schedule or in any update to the
Disclosure Schedule shall be deemed to be a representation and warranty made by
the Company in this Agreement.

     9.2  Indemnification by the Indemnitors.

          (a) From and after the Closing Date (but subject to Section 9.1(a)),
the Indemnitors, shall hold harmless and indemnify each of the Indemnitees from
and against, and shall compensate and reimburse each of the Indemnitees for, any
Damages which are directly or indirectly suffered or incurred by any of the
Indemnitees or to which any of the Indemnitees may otherwise become subject
(regardless of whether or not such Damages relate to any third-party claim) and
which arise from or as a result of, or are directly or indirectly connected
with: (i) any inaccuracy in or breach of any representation or warranty set
forth in Section 2 or in the Closing Certificates (after giving effect to any
update to the Disclosure Schedule delivered by the Company to Parent prior to
the Closing); (ii) any breach of any covenant or obligation of the Company or
the Signing Shareholder (including the covenants set forth in Sections 4 and 5);
or (iii) any Legal Proceeding relating to any inaccuracy or breach of the type
referred to in clause "(i)" or "(ii)" above (including any Legal Proceeding
commenced by any Indemnitee for the purpose of enforcing any of its rights under
this Section 9).

          (b)  The Company acknowledges and agrees that, if the Surviving
Corporation suffers, incurs or otherwise becomes subject to any Damages as a
result of or in connection with any inaccuracy in or breach of any
representation, warranty, covenant or obligation, then

                                       31
<PAGE>

(without limiting any of the rights of the Surviving Corporation as an
Indemnitee) Parent shall also be deemed, by virtue of its ownership of the stock
of the Surviving Corporation, to have incurred Damages as a result of and in
connection with such inaccuracy or breach.

     9.3  Threshold.

          (a)  The Indemnitors shall not be required to make any indemnification
payment pursuant to Section 9.2(a) for any inaccuracy in or breach of any of
their representations and warranties set forth in Section 2 until such time as
the total amount of all Damages (including the Damages arising from such
inaccuracy or breach and all other Damages arising from any other inaccuracies
in or breaches of any representations or warranties) that have been directly or
indirectly suffered or incurred by any one or more of the Indemnitees, or to
which any one or more of the Indemnitees has or have otherwise become subject,
exceeds $50,000 in the aggregate. If the total amount of such Damages exceeds
$50,000 then the Indemnitees shall be entitled to be indemnified against and
compensated and reimbursed for the full amount of such damages (and not merely
the portion of such Damages exceeding $50,000).

     9.4  Escrow Fund; Ceiling.

          (a) Notwithstanding anything else herein, indemnification under this
Section 9 shall be satisfied solely from the Escrow Fund (described in Section
9.4(b) below). Except for any Damages from any fraud or intentional
misrepresentation, indemnification under this Section 9 shall be the sole and
exclusive remedy of the Indemnitees for any and all breaches of representations
and warranties contained in Section 2 hereof.

          (b) Each Indemnitor, Parent, the Company and a banking institution
selected by Parent as escrow agent ("Escrow Agent") shall enter into the Escrow
Agreement (modified as requested by the Escrow Agent), under which, on the terms
and conditions set forth therein, a portion of the amounts to be paid to the
Indemnitors hereunder will be escrowed to pay amounts payable to Parent or the
Company under this Section 9.

The Escrow Fund shall consist of the amount set forth in Section 1.6.  The
amount remaining in the Escrow Fund less the sum of any amounts payable from the
Escrow Fund that are subject to a claim made by Parent or the Company under this
Section 9 not yet resolved shall be distributed to the shareholders of the
Company on the nine (9) month anniversary of the Closing Date.

     9.5  Claim Procedure. Upon delivery to the Escrow Agent and the Indemnitors
in accordance with Section 11.5 on or before the last day of the period set
forth in Section 9.1(a) above of a certificate signed by any officer of Parent
(an "Officer's Certificate")

          (a) stating that Parent or the Company has paid or properly accrued or
reasonably anticipates that Parent or the Company will have to pay or accrue
Damages in an aggregate stated amount, and stating that Parent or the Company is
entitled to indemnity pursuant to this Agreement with respect to such amount,
and

          (b) specifying the individual items of Damages included in the amount
so stated, the date each such item was paid or properly accrued, or the basis
for such anticipated liability;

                                       32
<PAGE>

The Escrow Agent shall, subject to the provisions of Section 9.6 hereof, deliver
to Parent as promptly as practicable, an amount from the Escrow Fund sufficient
to fully indemnify Parent or the Company against such Damages.

     9.6  Objections to Claims.    At the time of delivery of any Officer's
Certificate to the Escrow Agent, a duplicate copy of such certificate shall be
delivered to the Indemnitors and for a period of thirty (30) days after such
delivery, the Escrow Agent shall make no delivery of cash pursuant to Section
9.5 hereof unless the Escrow Agent shall have received written authorization
from the Indemnitors to make such delivery.  After the expiration of such 30-day
period, the Escrow Agent shall make delivery of the amount requested in the
Officer's Certificate in accordance with Section 9.5 hereof, provided that no
such payment or delivery need be made if the Indemnitors who received a majority
of the Parent Company Stock in the Merger shall object in a written statement to
the claim made in the Officer's Certificate, and such statement shall have been
delivered to Parent (with a copy to the Escrow Agent) prior to the expiration of
such 30-day period.

     9.7  Resolution of Conflicts.

          (a) In case the Indemnitors who received a majority of the Parent
Company stock in the Merger shall so object in writing to the indemnity of
Parent or the Company in respect of any claim or claims made in any Officer's
Certificate, the Indemnitors who received a majority of the Parent Company stock
in the Merger and Parent (acting on its own behalf or on behalf of the Company)
shall attempt in good faith to agree upon the rights of the respective parties
with respect to each of such claims. If the Indemnitors who received a majority
of the Parent Company stock in the Merger and Parent should so agree, a
memorandum setting forth such agreement shall be prepared and signed by both
parties and shall be furnished to the Escrow Agent who shall thereupon promptly
pay the agreed upon amount of the claim to Parent.

          (b) If no such agreement can be reached after good faith negotiation,
the claim shall be submitted to non-binding mediation under the rules then in
effect under the American Arbitration Association, or such other forum as the
parties may select. Each party shall have in attendance at such mediation
persons who have actual authority to bind the party to any settlement reached.
If the matter cannot be settled through mediation, then the claim shall be
submitted to binding arbitration under the following rules:

               (i) Unless otherwise agreed by the parties, all such claims shall
be decided in San Jose, California by a single arbitrator, acting under the
Commercial Rules of the American Arbitration Association except as modified
herein. Either party may initiate the arbitration following failure of mediation
to resolve the issue by filing a demand for arbitration with the American
Arbitration Association, and simultaneously delivering a copy of such demand to
the other party.

              (ii) Unless the parties agree to a mutually acceptable arbitrator
within thirty (30) days of a demand for arbitration, the arbitrator shall be
selected by the American Arbitration Association.

                                       33
<PAGE>

             (iii) Unless otherwise agreed by the parties, the arbitrator shall
be a business attorney in practice for at least 10 years, with substantial
experience in the negotiating and drafting of business acquisition agreements.

              (iv) It is the intent of the parties that the arbitration be held
in an efficient, economical and expeditious manner. Accordingly, the parties
shall meet in a pre-hearing conference as promptly as practicable after
selection of the arbitrator to establish the scope and extent of all discovery
and the schedule of the arbitration. Discovery shall be limited to that
necessary to resolve the disputed issues, in the judgment of the arbitrator. If
any party wishes to take discovery, including document productions,
interrogatories or depositions, a request to do so must be submitted to the
arbitrator in accordance with the procedures determined at the pre-hearing
conference. The arbitrator in his sole discretion may allow limited discovery,
all of which must be completed within 20 business days of the arbitrator's
directive unless extended for good cause by the arbitrator.

               (v) The arbitrator shall not be bound by rules of evidence or
judicial procedures regarding the conduct of the hearing and shall be obligated
to follow California substantive law.

              (vi) The arbitrator's authority shall be limited to determining
whether the claim gives rise to a right to indemnification under the provisions
of this Section 9 and, if so, the amount of Damages as to such claim. No other
issue involving interpretation of this Agreement shall be submitted to the
arbitrator without the consent of both parties.

             (vii) The decision of the arbitrator as to the validity and amount
of Damages and the amounts in (c) below shall, subject to the above limitations,
be binding and conclusive upon the parties of this Agreement. The arbitrator
shall issue such decision, including a brief statement of the reasons for the
award and the calculation of damages awarded, within 25 days after completion of
the arbitration hearing and deliver such decision to the Escrow Agent.

          (c) Judgment upon any award rendered by the arbitrators may be entered
in any court having jurisdiction. The non-prevailing party shall pay the
reasonable expenses (including attorneys' fees) of the prevailing party and the
arbitrator fees and administrative expenses associated with the arbitration
(which expenses and fees, in the event the Parent is the prevailing party, shall
constitute Damages to be satisfied solely from the Escrow Fund).

     9.8  Defense of Third Party Claims.  In the event of the assertion or
commencement by any Person of any claim or Legal Proceeding (whether against the
Surviving Corporation, against Parent or against any other Person) with respect
to which the Company may become obligated to hold harmless, indemnify,
compensate or reimburse any Indemnitee pursuant to this Section 9, Parent shall
have the right, at its election, to proceed with the defense of such claim or
Legal Proceeding on its own.  If Parent so proceeds with the defense of any such
claim or Legal Proceeding:

          (a) all reasonable expenses relating to the defense of such claim or
Legal Proceeding shall be borne and paid exclusively by the Company and;

                                       34
<PAGE>

          (b) Parent shall have the right to settle, adjust or compromise such
claim or Legal Proceeding with the consent of the Indemnitors who received a
majority of the Parent Company Stock; provided, however, that such consent shall
not be unreasonably withheld.

     Parent shall give the Indemnitors prompt notice of the commencement of any
such Legal Proceeding against Parent or the Surviving Corporation; provided,
however, that any failure on the part of Parent to so notify the Indemnitors
shall not limit any of the obligations of the Company under this Section 9
(except to the extent such failure materially prejudices the defense of such
Legal Proceeding).

        9.9 Exercise of Remedies by Indemnitees Other Than Parent. No Indemnitee
(other than Parent or any successor thereto or assign thereof) shall be
permitted to assert any indemnification claim or exercise any other remedy under
this Agreement unless Parent (or any successor thereto or assign thereof) shall
have consented to the assertion of such indemnification claim or the exercise of
such other remedy.

SECTION 10. REGISTRATION OF THE PARENT COMMON STOCK; COMPLIANCE WITH THE
            SECURITIES ACT.

       10.1   Definitions. As used in this Section 10 the following terms shall
have the following respective meanings:

              (a) "Registrable Parent Common Stock" shall mean the Parent Common
Stock issued pursuant to this Agreement;

              (b) "Registration Statement" shall include any final prospectus,
exhibit, supplement or amendment included in or relating to the Registration
Statement referred to in Section 10.2; and

              (c) "Untrue Statement" shall include any untrue statement or
alleged untrue statement, or any omission or alleged omission to state in the
Registration Statement a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

      10.2   Registration Procedures and Expenses Parent is obligated to do the
following:

      Parent shall, within 75 days following the Closing Date:

             (a) prepare and file with the SEC a registration statement on Form
S-3 in order to register with the SEC under the Securities Act a sale by the
Shareholders on a delayed or continuous basis pursuant to Rule 415 under the
Securities Act any or all of the Registrable Parent Common Stock through the
automated quotation system of the Nasdaq National Market System or the
facilities of any national securities exchange on which Parent's Common Stock is
then traded, or in privately-negotiated transactions (a "Registration
Statement") (notwithstanding anything to the contrary expressed or implied
herein, if a registration statement on Form S-3, or any substitute form, is not
then available for registration of the Registrable Parent Common Stock, Parent
shall be obligated instead to prepare and file with the SEC a registration
statement on Form S-1 in order to register the Registrable Parent Common Stock
under the Securities Act

                                       35
<PAGE>

and such registration statement will be a "Registration Statement" for the
purposes of this Agreement);

            (b) use its best efforts, subject to receipt of necessary
information from the Shareholders, to cause such Registration Statement to
become effective as promptly after filing as practicable;

            (c) notify each Shareholder, at any time when a prospectus relating
to such Registration Statement is required to be delivered under the Securities
Act, of the happening of any event as a result of which the prospectus included
in or relating to such Registration Statement contains an untrue statement of a
material fact or omits to state any fact necessary to make the statements
therein not misleading;

            (d) prepare and file with the SEC such amendments and supplements to
such Registration Statement and the prospectus used in connection therewith as
may be necessary to keep such Registration Statement effective until termination
of such obligation as provided in Section 10.5 below;

            (e) furnish to each Shareholder such number of copies of
prospectuses in conformity with the requirements of the Securities Act, in order
to facilitate the public sale or other disposition of all or any of the
Registrable Parent Common Stock by the Shareholders;

            (f) file such documents as may be required of Parent for normal
securities law clearance for the resale of the Registrable Parent Common Stock
in which states of the United States as may be reasonably requested by each
Shareholder provided, however, that Parent shall not be required in connection
with this paragraph (e) to qualify as a foreign corporation or execute a general
consent to service of process in any jurisdiction;

            (g) use its best efforts to cause all Registrable Parent Common
Stock to be listed on each securities exchange, if any, on which equity
securities by Parent are then listed; and

            (h) bear all expenses in connection with the procedures in
paragraphs (a) through (f) of this Section 10.2, other than (i) fees and
expenses, if any, of counsel or other advisers to the Shareholders, and (ii) any
expenses relating to the sale of the Registrable Parent Common Stock by the
Shareholders, including broker's commission, discounts or fees and transfer
taxes.

     10.3  Indemnification

           (a) Parent agrees to indemnify and hold harmless each Shareholder
from and against any losses, claims, damages or liabilities to which such
Shareholder may become subject (under the Securities Act or otherwise) insofar
as such losses, claims, damages or liabilities (or actions or proceedings in
respect thereof) arise out of, or are based upon, any Untrue Statement on the
effective date of the Registration Statement, or arise out of any failure by
Parent to fulfill any undertaking included in the Registration Statement and
Parent will reimburse such Shareholder for any reasonable legal or other
expenses reasonably incurred in investigating, defending or preparing to defend
any such action, proceeding or claim; provided, however, that

                                       36
<PAGE>

Parent shall not be liable in any such case to the extent that such loss, claim,
damage or liability arises out of, or is based upon, an Untrue Statement made in
such Registration Statement in reliance upon and in conformity with written
information furnished to Parent by or on behalf of such Shareholder specifically
for use in preparation of the Registration Statement, or any statement or
omission in any prospectus that is corrected in any subsequent prospectus that
was delivered to the Shareholder prior to the pertinent sale or sales by the
Shareholder.

           (b) Each Shareholder, severally and not jointly, agrees to indemnify
and hold harmless Parent (and each person, if any, who controls Parent within
the meaning of Section 15 of the Securities Act, each officer of Parent who
signs the Registration Statement and each director of Parent) from and against
any losses, claims, damages or liabilities to which Parent (or any such officer,
director or controlling person) may become subject (under the Securities Act or
otherwise), insofar as such losses, claims, damages or liabilities (or actions
or proceedings in respect thereof) arise out of, or are based upon, any Untrue
Statement contained in the Registration Statement on the effective date thereof
if such Untrue Statement was made in reliance upon and in conformity with
written information furnished by or on behalf of such Shareholder specifically
for use in preparation of the Registration Statement, and such Shareholder will
reimburse Parent (or such officer, director or controlling person), as the case
may be, for any legal or other expenses reasonably incurred in investigating,
defending or preparing to defend any such action, proceeding or claim; provided
that in no event shall any indemnity by a Shareholder under this Section 10.3
exceed the net proceeds received by such Shareholder from the sale of the Parent
Common Stock covered by such Registration Statement.

          (c) Promptly after receipt by any indemnified person of a notice of a
claim or the beginning of any action in respect of which indemnity is to be
sought against an indemnifying person pursuant to this Section 10.3, such
indemnified person shall notify the indemnifying person in writing of such claim
or of the commencement of such action, and, subject to the provisions
hereinafter stated, in case any such action shall be brought against an
indemnified person and such indemnifying person shall have been notified
thereof, such indemnifying person shall be entitled to participate therein, and,
to the extent it shall wish, to assume the defense thereof, with counsel
reasonably satisfactory to such indemnified person. After notice from the
indemnifying person to such indemnified person of its election to assume the
defense thereof, such indemnifying person shall not be liable to such
indemnified person for any legal expenses subsequently incurred by such
indemnified person in connection with the defense thereof; provided, however,
that if there exists or shall exist a conflict of interest that would make it
inappropriate, in the opinion of counsel to the indemnified person, for the same
counsel to represent both the indemnified person and such indemnifying person or
any affiliate or associate thereof, the indemnified person shall be entitled to
retain its own counsel at the expense of such indemnifying person; provided,
however, that no indemnifying person shall be responsible for the fees and
expenses of more than one separate counsel for all indemnified parties.

           (d) If the indemnification provided for in this Section 10.3 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
in such

                                       37
<PAGE>

proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission; provided, that in
no event shall any contribution by a Shareholder hereunder exceed the net
proceeds received by such Shareholder from the sale of the Parent Common Stock
covered by the Registration Statement.

     10.4  Reporting Requirements.

           (a)  Parent agrees to use its best efforts to:

                (i) make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act;

                (ii) file with the SEC in a timely manner all reports and other
documents required of Parent under the Securities Act and the Securities
Exchange Act of 1934; and

                (iii) so long as any of the Shareholders own Registrable
Securities, to furnish to the Shareholders forthwith upon request (1) a written
statement by Parent as to whether it complies with the reporting requirements of
said Rule 144, the Securities Act and Securities Exchange Act of 1934, or
whether it qualifies as a registrant whose securities may be resold pursuant to
SEC Form S-3, (2) a copy of the most recent annual or quarterly report of

     Parent and such other reports and documents so filed by Parent, and (3)
such other information as may be reasonably requested in availing the
Shareholders of any rule or regulation of the SEC that would permit the selling
of the Registrable Securities without registration.

     10.5  Termination of Obligations   The obligations of Parent pursuant to
Sections 10.2 through 10.5 hereof shall cease and terminate upon the earlier to
occur of (i) such time as all of the Registrable Parent Common Stock have been
resold, or (ii) such time as all of the Registrable Parent Common Stock may be
sold during any 90 day period pursuant to Rule 144.

     10.6  Assignability of Registration Rights   The registration rights set
forth in this Section 10 are not assignable other than to an affiliate of a
Shareholder.

SECTION 11.  MISCELLANEOUS PROVISIONS

     11.1  Further Assurances.  Each party hereto shall execute and cause to be

expenses (including legal fees and accounting fees) that have been incurred or
that are incurred by such party in connection with the transactions contemplated
by this Agreement, including all fees, costs and expenses incurred by such party
in connection with or by virtue of (a) the investigation and review conducted by
Parent and its Representatives with respect to the Company's business (and the

such investigation and review), (b) the negotiation, preparation and review of
this Agreement (including the Disclosure Schedule) and all agreements,

          THIS ESCROW AGREEMENT (this "Escrow Agreement") is made and entered
into as of June 2, 1999, by and among Asyst Technologies, Inc., a California
corporation ("Parent"), PROGRESSIVE SYSTEM TECHNOLOGIES, INC., a Texas
corporation (the "Company"), the shareholders of the Company listed on Exhibit A
hereto (the "Shareholders"), and STATE STREET BANK AND TRUST COMPANY OF
CALIFORNIA, N.A., a national banking association (the "Escrow Agent").

                                    RECITALS

          A.  Parent, Merger Sub Acquisition Corp., a Texas corporation and
wholly-owned subsidiary of Parent ("Merger Sub"), the Company, and certain
shareholders of the Company have entered into an Agreement and Plan of Merger
and Reorganization, dated June 2, 1999 (the "Reorganization Agreement") which
provides that Merger Sub will be merged with and into the Company (the
"Merger"), with the Company being the surviving corporation, on the terms and
conditions set forth therein.  Capitalized terms used and not otherwise defined
in this Escrow Agreement shall have the meanings assigned to them in the
Reorganization Agreement, a copy of which is attached hereto.

          B.  The Reorganization Agreement contemplates the establishment of an
escrow arrangement to secure the indemnification obligations of the Shareholders
to each of the Indemnitees.  As a condition precedent to Parent's consummation
of the transactions contemplated by the Reorganization Agreement and related
agreements, Parent has required that the Company and the Shareholders enter into
this Escrow Agreement; and the Shareholders desire, and have agreed, to enter
into this Escrow Agreement in order to induce Parent to consummate the Merger.

          C.  By virtue of the Shareholders' execution of this Escrow Agreement,
the Shareholders have agreed to be bound by the terms of this Escrow Agreement,
including without limitation (i) the establishment of this escrow to secure
their indemnification obligations under Section 9.2 of the Reorganization
Agreement, (ii) the appointment of the Majority Shareholders (as defined in
Section 3(b)) as their representative for the purposes of this Escrow Agreement
and as attorney-in-fact and agent for and on behalf of each of the Shareholders,
and the taking by the Majority Shareholders of any and all actions and the
making of any decisions required or permitted to be taken or made by them under
this Escrow Agreement, and (iii) all of the other terms, conditions and
limitations in this Escrow Agreement.

                                   AGREEMENT

          The parties to this Escrow Agreement, intending to be legally bound,
agree as follows:

          1. Appointment of the Escrow Bank. Parent, the Company, the
Shareholders and the Majority Shareholders hereby appoint State Street Bank and
Trust Company of California, N.A. to act as the escrow agent under this Escrow
Agreement and State Street Bank and Trust Company of California, N.A. hereby
accepts such appointment.

                                       1

         2.  Deposit of Funds

                (a) Simultaneously with the Closing, 50,000 shares of Parent
Common Stock (the "Escrow Stock") will be deposited by Parent at the direction
of the Shareholders with the Escrow Agent. The amount delivered and deposited by
each Shareholder shall be as set forth opposite the names of the Shareholders on
Exhibit A hereto. The Escrow Stock will be registered in the names of the Escrow
Agent on behalf of the Shareholders who otherwise would be entitled to receive
them as a result of the Merger as set forth in Exhibit A.

                (b) The Escrow Agent shall acknowledge by written receipt on the
date hereof that the Escrow Stock has been delivered and deposited with the
Escrow Agent and that the Escrow Agent will hold the Escrow Stock in a separate
account (the "Escrow Fund") pursuant to the terms and conditions hereof.

                (c) The value of each share of Escrow Stock for purposes of this
Escrow Agreement shall be equal to $25.60, adjusted as appropriate to reflect
any stock split, reverse stock split, stock dividend or similar transaction
effected by the Company after the Closing Date (the "Valuation Price"). Parent
shall notify the Escrow Agent of any adjustment of the Valuation Price. Unless
and until the Escrow Agent receives written notice from Parent of any adjustment
of the Valuation Price, the Escrow Agent may assume without inquiry that no such
adjustment has been or is required to be made.

     3.   Distributions.

                (a) Dividends, Etc.  Any cash, securities or other property
distributable (whether by way of dividend, stock split or otherwise) in respect
of or in exchange for any shares of Escrow Stock (including ordinary dividends)
shall not be distributed to the Shareholders, but rather shall be distributed by
Parent to the Escrow Agent and held by the Escrow Agent in the Escrow Fund.  At
the time any shares of Escrow Stock are required to be released from the Escrow
Fund to any person pursuant to this Escrow Agreement, any cash, securities or
other property previously received by the Escrow Agent in respect of or in
exchange for such shares of Escrow Stock (including ordinary dividends) shall be
released from the Escrow Fund to such person.  Unless and until the Escrow Agent
shall receive cash, securities or other property distributable in respect of or
in exchange for any shares of Escrow Stock, the Escrow Agent may assume without
inquiry that no such property has been, or is required to be, distributed to it
and shall be obligated only to hold in the Escrow Fund the shares of Escrow
Stock and such other property as has actually been delivered to it.

                (b) Investment of Cash Received. The Escrow Agent shall invest
any cash received pursuant to Section 3(a) or any other provision of this Escrow
Agreement at, and pursuant to, the written direction of a majority in interest
of the Shareholders (based on the percentages set forth on Exhibit A hereto)
(the "Majority Shareholders") in Eligible Investments (as defined below) and
shall not be responsible or liable for any loss accruing from any investment
made in accordance herewith. All earnings received from the investment of the
cash in the Escrow Fund shall be credited to, and shall become a part of, the
Escrow Fund (and any losses on such investments shall be debited to the Escrow
Fund). The Escrow Agent shall have no liability for any investment losses,
including any losses on any investment required to be

                                       2
<PAGE>

liquidated prior to maturity in order to make a payment required hereunder.
"Eligible Investments" as used in this Section 3(b) means (i) obligations issued
or guaranteed by the United States of America or any agency or instrumentality
thereof (provided that the full faith and credit of the United States is pledged
in support thereof); (ii) obligations (including certificates of deposit and
banker's acceptances) of any domestic commercial bank having capital and surplus
in excess of $500,000,000; (iii) repurchase obligations for underlying
securities of the type described in clause (i); or (iv) shares of money market
funds rated in the highest rating categories by Moody's and Standard & Poor's.
In the absence of written direction from the Majority Shareholders as to how
cash in the Escrow Fund should be invested, the Escrow Agent shall invest such
cash in the SSgA U.S. Treasury Money Market Fund, which is a money market mutual
fund registered under the Investment Company Act of 1940, the principal of which
is invested in obligations issued or guaranteed by the United States government.
Interest on any such investment shall be allocated to the Shareholders in
accordance with their percentage interests in the Escrow Fund set forth in
Exhibit A.

     4. Voting of Escrow Shares. Each Shareholder shall be entitled to instruct
the Escrow Agent as to how shares of Escrow Stock attributable to such
Shareholder are to be voted. Each Shareholder may instruct the Escrow Agent with
respect to a percentage of the total shares of Escrow Stock held in the Escrow
Fund from time to time corresponding to such Shareholder's percentage interest
in the Escrow Fund set forth in Exhibit A. In the absence of such directions,
the Escrow Agent shall not vote the shares of Escrow Stock or take any other
action as registered owner of the Escrow Stock. The Escrow Agent need not
forward to the Shareholders or anyone else any copies of annual or quarterly
reports, proxies or other documents received by it. Parent agrees to furnish
such materials directly to the Shareholders, so that they, in turn, may exercise
their voting and other rights as beneficial owners of the Escrow Stock. The
Escrow Agent shall be under no obligation to itself preserve, protect or
exercise rights in the Escrow Stock, and shall be responsible only for
reasonable measures to maintain the physical safekeeping thereof, and otherwise
to perform and observe such duties on its part as are expressly set forth in
this Escrow Agreement.

     5. Transferability. The interests of Shareholders in the Escrow Fund and in
the Escrow Stock shall not be assignable or transferable, other than by
operation of law. No transfer of any of such interests by operation of law shall
be recognized or given effect until the Escrow Agent shall have received written
notice of such transfer.

     6. Legend. Each certificate representing a share of Escrow Stock shall be
imprinted with a legend in substantially the following form:

     THE TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT
     TO THE CONDITIONS SPECIFIED IN THE ESCROW AGREEMENT, DATED AS OF JUNE 2,
     1999 BETWEEN THE ISSUER AND THE ORIGINAL HOLDER THEREOF, AND THE ISSUER
     RESERVES THE RIGHT TO REFUSE THE TRANSFER OF SUCH SECURITIES UNTIL SUCH
     CONDITIONS HAVE BEEN FULFILLED WITH RESPECT TO SUCH TRANSFER. A COPY OF THE
     CONDITIONS SHALL BE FURNISHED BY THE ISSUER TO THE HOLDER HEREOF UPON
     WRITTEN REQUEST AND WITHOUT CHARGE.

                                       3

     7. Disbursement of Escrowed Funds.

        7.1  Claim Notice. If an Indemnitee determines in good faith that there
is or has been (a) any inaccuracy in or breach of any representation or warranty
made by the Company or the Signing Shareholder set forth in Section 2 of the
Reorganization Agreement, or in the Closing Certificates, (b) any breach of any
covenant or obligation of the Company or the Signing Shareholder (including the
covenants set forth in Sections 4 or 5 of the Reorganization Agreement), or (c)
any Legal Proceeding relating to any inaccuracy or breach of the type referred
to in clause "(a)" or "(b)" above (including any Legal Proceeding commenced by
any Indemnitee for the purpose of enforcing any of its rights under Section 9 of
the Reorganization Agreement) that entitles such Indemnitee to be indemnified
pursuant to Section 9 of the Reorganization Agreement (a "Claim") then Parent
shall deliver to both the Majority Shareholders and the Escrow Agent a written
notice of such Claim (a "Claim Notice"), setting forth (i) a brief description
of the circumstances supporting the Indemnitee's belief that such possible
inaccuracy, breach or Legal Proceeding exists or has occurred, and (ii) to the
extent possible, a non-binding, preliminary estimate of the aggregate dollar
amount of all Damages that have arisen and may arise as a result of such
possible inaccuracy or breach (such aggregate amount being referred to as the
"Claim Amount").

        7.2  Response Notice. Within thirty (30) days after the delivery of a
Claim Notice to the Majority Shareholders and the Escrow Agent, the Majority
Shareholders shall deliver to the Indemnitee, with a copy to the Escrow Agent, a
written notice (the "Response Notice") containing: (a) instructions to the
Escrow Agent to the effect that the Escrow Agent shall withdraw from the Escrow
Fund and pay to the Indemnitee an amount equal to the entire Claim Amount set
forth in such Claim Notice; or (b) instructions to the Escrow Agent to the
effect that the Escrow Agent shall withdraw from the Escrow Fund an amount equal
to a specified portion (but less than the entire amount) of the Claim Amount set
forth in such Claim Notice, together with a statement that the remaining portion
of such Claim Amount is being disputed; or (c) a statement that the Claim and
the entire Claim Amount set forth in such Claim Notice is being disputed. If no
Response Notice is received by the Indemnitee and the Escrow Agent from the
Majority Shareholders within thirty (30) days after the delivery of a Claim
Notice to the Majority Shareholders and the Escrow Agent, then the Majority
Shareholders shall be deemed to have given instructions to the Escrow Agent that
an amount of the Escrow Fund equal to the entire Claim Amount set forth in such
Claim Notice is to be withdrawn from the Escrow Fund and paid to the Indemnitee.

        7.3  Disbursement of Escrowed Funds to Indemnitee

             (a) If the Majority Shareholders give (or are deemed to have given)
instructions to the Escrow Agent to the effect that the Escrow Agent shall
withdraw from the Escrow Fund and pay to the Indemnitee an amount in shares of
Escrow Stock, valued at the Valuation Price, equal to the entire Claim Amount
set forth in a Claim Notice, then the Escrow Agent shall promptly, following the
required delivery date for the Response Notice, (i) transfer, and deliver to
Indemnitee such shares of Escrow Stock in such amount held in the Escrow Fund
(or such lesser amount of Escrow Stock as is then held in the Escrow Fund) and
(ii) the Escrow Agent shall continue to hold the remaining portion of the Escrow
Fund pursuant to this Escrow Agreement.

                                       4
<PAGE>

        (b) If a Response Notice delivered by the Majority Shareholders in
response to a Claim Notice contains instructions to the Escrow Agent to the
effect that the Escrow Agent shall withdraw from the Escrow Fund and pay to the
Indemnitee an amount equal to a specified portion (but not the entire amount) of
the Claim Amount set forth in such Claim Notice, then (i) the Escrow Agent shall
promptly following the required delivery date for the Response Notice transfer
and deliver to the Indemnitee such lesser amount (or such lesser amount of
Escrow Stock as is then held in the Escrow Fund) and (ii) the Escrow Agent shall
continue to hold the remaining portion of the Escrow Fund pursuant to this
Escrow Agreement.

        (c) If a Response Notice delivered by the Majority Shareholders in
response to a Claim Notice contains a statement that all or a portion of the
Claim Amount set forth in such Claim Notice is being disputed (such Claim Amount
or the disputed portion thereof being referred to as the "Disputed Amount"),
then, the Escrow Agent shall continue to hold in the Escrow Fund Escrow Stock
equal to the Disputed Amount or such lesser amount that remains in the Escrow
Fund.  Such Escrow Stock shall continue to be held in the Escrow Fund until
receipt by the Escrow Agent of (i) a notice executed by the Indemnitee and the
Majority Shareholders setting forth instructions to the Escrow Agent regarding
the release of such Escrow Stock or (ii)  a copy of a non-appealable court order
or a court order for which the appeal period has expired containing instructions
to the Escrow Agent regarding the release of such Escrow Stock.  The Escrow
Agent shall thereupon release the Escrow Stock from the Escrow Fund in
accordance with the instructions set forth in such notice or order.

        (d) Any distribution of Escrow Stock to the Shareholders pursuant to any
provision of this Escrow Agreement shall be made to them at their addresses and
in the percentage interests set forth in Exhibit A and shall be deemed to have
been made when the Escrow Agent instructs the stock transfer agent of the Escrow
Stock to issue and mail the appropriate number of shares of Escrow Stock.

     8. Majority Shareholders.

        8.1  The Shareholders hereby irrevocably appoint the Majority
Shareholders as their agent for purposes of this Escrow Agreement, and the
Majority Shareholders hereby accept such appointment as the Shareholders' agent.
Parent and the Escrow Agent shall be entitled to deal exclusively with the
Majority Shareholders on all matters relating to this Escrow Agreement, and
shall be entitled to rely conclusively (without further evidence of any kind
whatsoever) on any document executed or purported to be executed on behalf of
any Shareholder by the Majority Shareholders, and on any other action taken or
purported to be taken on behalf of any Shareholder by the Majority Shareholders,
as fully binding upon such Shareholder.  If for any reason there are no Majority
Shareholders at any time, all references herein to the Majority Shareholders
shall be deemed to refer to the Shareholders.

        8.2  Neither the Majority Shareholders nor any agent employed by them
shall be liable to any Shareholder relating to the performance of their duties
under the Reorganization Agreement or this Escrow Agreement for any errors in
judgment, negligence, oversight, breach of duty or otherwise except to the
extent it is finally determined in a court of competent jurisdiction by clear
and convincing evidence that the actions taken or not taken by the Majority
Shareholders constituted fraud or were taken or not taken in bad faith.  The
Majority

                                       5
<PAGE>

Shareholders shall be indemnified and held harmless by the Shareholders in the
amounts determined by applying the procedures specified in this Escrow Agreement
against all expenses (including attorneys' fees), judgments, fines and other
amounts paid or incurred in connection with any action, suit, proceeding or
claim to which the Majority Shareholders are made a party by reason of the fact
that they were acting as the Shareholders' agent pursuant to the Reorganization
Agreement or this Escrow Agreement; provided, however, that the Majority
Shareholders shall not be entitled to indemnification hereunder to the extent it
is finally determined in a court of jurisdiction by clear and convincing
evidence that the actions taken or not taken by the Majority Shareholders
constituted fraud or were taken or not taken in bad faith. The Majority
Shareholders shall be protected in acting upon any notice, statement or
certificate believed by it to be genuine and to have been furnished by the
appropriate person and in acting or refusing to act in good faith or any matter.

        8.3  A decision, act, consent or instruction of the Majority
Shareholders shall be made in writing and shall constitute a decision of all the
Shareholders, and shall be final, binding and conclusive upon each of the
Shareholders, and Parent, the Escrow Agent and the Company may rely upon any
decision, act, consent or instruction of the Majority Shareholders as being the
decision, act, consent or instruction of each and all of the Shareholders.
Parent, the Escrow Agent and the Company are hereby relieved from any liability
to any person for any acts done by them in accordance with such decision, act,
consent or instruction of the Majority Shareholders.

    9.  Release of Escrowed Funds

        9.1  If on March 2, 2000, there are no outstanding Claims, the Escrow
Agent shall release and pay to the Shareholders the Escrow Stock and any other
assets held in the Escrow Fund, such payment to be made to each Shareholder by
multiplying the aggregate amount of the Escrow Fund by the percentage set forth
opposite such Shareholder's name on Exhibit A hereto.  If, on such date, there
are one or more outstanding Claims, the Escrow Agent shall release and pay to
the Shareholders only an amount equal to the amount by which the Escrow Fund
exceeds the aggregate amount of the outstanding Claims and an amount equal to
all outstanding Claims will continue to be held until all such Claims have been
resolved.  If any funds remain in the Escrow Fund after the resolution and
payment provided for in the immediately preceding sentence, the Escrow Agent
shall release and pay such remainder to the Shareholders with each Shareholder
receiving an amount determined by multiplying such remainder by the percentage
set forth opposite such Shareholder's name on Exhibit A hereto.

        9.2  Upon release of the Escrow Fund pursuant to Section 9.1 of this
Escrow Agreement, any and all other assets remaining in the Escrow Fund, less
any taxes required under applicable law to be withheld by the Escrow Agent with
respect to the Escrow Fund or such other assets, shall be paid by the Escrow
Agent to the party or parties to whom such funds are being released.

    10. Fees and Expenses

        10.1 The Escrow Agent agrees to perform its duties hereunder in
accordance with the fee schedule attached as Exhibit B hereto, which may be
subject to change on an annual

                                       6
<PAGE>

basis (the "Escrow Agent Fees"). In addition to the Escrow Agent Fees, the
Escrow Agent shall be entitled to reimbursement on demand for all expenses
reasonably incurred in connection with the administration of the Escrow Fund
created hereby which are in excess of its compensation for normal services
hereunder, including without limitation, payment of any reasonable legal fees
incurred by the Escrow Agent in connection with resolution of any claim by any
party hereunder. Each of (a) Parent and (b) the Shareholders shall be liable for
one-half (1/2) of the Escrow Agent Fees and such other amounts due to Escrow
Agent and Parent shall be entitled to reimbursement from the Escrow Stock if any
such excess expenses are paid by Parent and not paid by the Shareholders within
thirty (30) days after written request for such payment is made by Parent
pursuant to Section 10.3.

        10.2 Except as may otherwise be provided herein, all expenses (including
attorneys' fees) incurred by any Shareholder in connection with this Escrow
Agreement shall be borne by such Shareholder.

        10.3 Thirty (30) days following the delivery of a notice in writing to
the Escrow Agent and the Majority Shareholders by Parent in respect of Section
10.1 or Section 11.5, unless the Majority Shareholders shall have paid the
Shareholders' portion of the Escrow Agent fees, the Escrow Agent shall transfer,
deliver and assign to Parent, in reimbursement of fees and expenses pursuant to
the last sentence of Section 10.1 or the first sentence of Section 11.5, such
amount of Escrow Stock held in the Escrow Fund as instructed by Parent.

    11. Duties of the Escrow Agent; Limitation of Escrow Agent's Liability

        11.1 The sole duty of the Escrow Agent, other than as herein specified,
shall be to receive and hold the Escrow Fund, subject to disbursement in
accordance with this Escrow Agreement, and the Escrow Agent shall be under no
duty to determine whether Parent, the Majority Shareholders or the Shareholders
are complying with the requirements of this Escrow Agreement or any other
agreement. Parent and the Shareholders acknowledge and agree that the Escrow
Agent (a) shall not be responsible for any of the agreements referred to herein
but shall be obligated only for performance of such duties as are specifically
set forth in this Escrow Agreement; (b) shall not be obligated to take any legal
or other action hereunder which might in its judgment involve any expense or
liability unless it shall have been furnished with acceptable indemnification;
(c) may rely on and shall be protected in acting or refraining from acting upon
any written notice, instruction, instrument, statement, request or document
furnished to it hereunder and believed by it to be genuine and to have been
signed or presented by the proper person, and shall have no responsibility for
determining the accuracy thereof, and (d) may consult counsel satisfactory to
it, and the opinion of such counsel, shall be full and complete authorization
and protection in respect of any action taken, suffered or omitted by it
hereunder in good faith and in accordance with the opinion of such counsel.

        11.2 Neither the Escrow Agent nor any of its directors, officers or
employees shall be liable to anyone for any action taken or omitted to be taken
by it or any of its directors, officers or employees hereunder except in the
case of Escrow Agent's willful misconduct or gross negligence.  In no event
shall the Escrow Agent be liable for incidental, consequential or punitive
damages.  Parent and the Shareholders, jointly and severally, covenant and agree
to

                                       7
<PAGE>

indemnify the Escrow Agent and its directors, officers and employees and hold
them harmless without limitation from and against any loss, liability or expense
of any nature incurred by the Escrow Agent arising out of or in connection with
this Escrow Agreement or with the administration of its duties hereunder,
including but not limited to reasonable legal fees and other costs and expenses,
except such loss, liability or expense caused by the Escrow Agent's willful
misconduct or gross negligence.

        11.3  Parent and the Shareholders, jointly and severally, agree to
assume any and all obligations imposed now or hereafter by any applicable tax
law with respect to the payment of Escrow Funds under this Escrow Agreement, and
to indemnify and hold the Escrow Agent and its directors, officers and employees
harmless from and against any taxes, additions for late payment, interest,
penalties and other expenses, that may be assessed against the Escrow Agent on
any such payment or other activities under this Escrow Agreement, except for
taxes payable by the Escrow Agent in respect of fees received by it hereunder.
Parent and the Shareholders undertake to instruct the Escrow Agent in writing
with respect to the Escrow Agent's responsibility for withholding and other
taxes, assessments or other governmental charges, certifications and
governmental reporting in connection with its acting as Escrow Agent under this
Escrow Agreement. Parent and the Shareholders, jointly and severally, agree to
indemnify and hold the Escrow Agent and its directors, officers and employees
harmless from any liability on account of taxes, assessments or other
governmental charges, including without limitation the withholding or deduction
or the failure to withhold or deduct same, and any liability for failure to
obtain proper certifications or to properly report to governmental authorities,
to which the Escrow Agent may be or become subject in connection with or which
arises out of this Escrow Agreement, including costs and expenses (including
reasonable legal fees), interest and penalties.

        11.4  The Escrow Agent shall have no more or less responsibility or
liability on account of any action or omission of any book-entry depository or
subescrow agent employed by the Escrow Agent than any such book-entry depository
or subescrow agent has to the Escrow Agent, except as to the extent that such
action or omission of any book-entry depository or subescrow agent was caused by
the Escrow Agent's own willful misconduct or negligence.

        11.5  As among themselves, each of (a) Parent and (b) the Shareholders
shall be liable for fifty percent (50%) of any amounts owed to the Escrow Agent
in satisfaction of any of the foregoing indemnification obligations and, subject
to the provisions of Sections 10.1 and 10.3 hereof, Parent shall be entitled to
reimbursement from the Escrow Fund of the Shareholders' share of any such loss,
liability or expense, if such share is paid by Parent.  The provisions of
Section 11.2 and 11.3 shall survive termination of this Escrow Agreement.

        11.6  In the event of any disagreement between Parent and the
Shareholders, or between them and any other person, resulting in adverse claims
or demands being made in connection with the assets hereunder, or in the event
that the Escrow Agent, in good faith, be in doubt as to what action it should
take hereunder, the Escrow Agent may, at its option, refuse to comply with any
claims or demands or it may refuse to take any other action hereunder, so long
as such disagreement continues or such doubt exists, and in any such event, the
Escrow Agent shall not be or become liable in any way or to any person for its
failure or refusal to act, and the Escrow Agent shall be entitled to continue so
to refrain from acting until (a) the rights of Parent

                                       8

<PAGE>

and the Shareholders shall have been fully and finally adjudicated by a court of
competent jurisdiction, or (b) all differences shall have been adjusted and all
doubt resolved by agreement between Parent or the Shareholders and the Escrow
Agent shall have been notified thereof in writing signed by or on behalf of all
such persons. The rights of the Escrow Agent under this Section 11.6 are in
addition to all other rights which it may have by law or otherwise.

    12. Replacement of the Escrow Agent.  The Escrow Agent may resign at any
time by giving sixty (60) days prior written notice to all parties hereto, but
will continue to serve until a successor is appointed by mutual agreement of the
Parent and the Majority Shareholders.  The Parent and the Majority Shareholders,
by mutual agreement, may at any time, and with or without cause, remove the
Escrow Agent by written notice to the Escrow Agent.  In the event the Escrow
Agent is removed or for any reason is unable to serve or fails to continue to
serve as the escrow agent hereunder, the Parent and the Majority Shareholders,
by mutual agreement, shall appoint a successor escrow agent.  Any successor
escrow agent shall execute and deliver an instrument accepting the appointment
as escrow agent hereunder and thereupon will have the same rights and duties as
the original Escrow Agent and be governed by the terms and conditions set forth
in this Escrow Agreement.

    13. General

        13.1  Other Agreements. Nothing in this Escrow Agreement is intended to
limit any of Parent's or the Shareholders' rights or obligations under the
Reorganization Agreement (or any agreement entered into in connection with the
transactions contemplated by the Reorganization Agreement).

        13.2  Governing Law. This Escrow Agreement shall be construed in
accordance with, and governed in all respects, by the internal laws of the State
of California (without giving effect to the conflict of laws).

        13.3  Successors and Assigns.  No party hereto may assign any of its
rights or obligations hereunder without the prior written consent of the other

its successors and assigns (if any); each undersigned Shareholder and his
respective personal representatives, executors, administrators, estates, heirs,
successors and permitted assigns (if any); Parent and its successors and
permitted assigns (if any); and the Escrow Agent and its successors and

        13.4  Severability.  In the event that if any provision of this Escrow
Agreement, or the application of any such provisions to any Person or set of
circumstances, shall be determined to be invalid, unlawful, void or
unenforceable to any extent, the remainder of this Escrow Agreement, and the
application of such provision to Persons or circumstances other than those as to
which it is determined to be invalid, unlawful, void or unenforceable, shall not
be impaired or otherwise affected and shall continue to be valid and enforceable
to the fullest extent permitted by law.

        13.5  Waiver.

              (a) No failure on the part of any Person to exercise any power,
right, privilege or remedy under this Escrow Agreement, and no delay on the part
of any Person in exercising any power, right, privilege or remedy under this
Escrow Agreement, shall operate as a waiver of such power, right, privilege or
remedy; and no single or partial exercise of any such power, right, privilege or
remedy shall preclude any other or further exercise thereof or of any other
power, right, privilege or remedy.

    Section 3.   General Representations and Warranties of the Company. The
Company hereby represents and warrants to, and covenants with, each Purchaser
that the following are and will be true and correct as of the date hereof and
as of the Closing Date.

            3.1  Organization; Qualification. The Company and each of its
subsidiaries is a corporation duly organized and validly existing under the laws
of the State of California (in the case of the Company) or other state of
incorporation and is in good standing under such laws. The Company and each of
its subsidiaries has all requisite corporate power and authority to own, lease
and operate its properties and assets, and to carry on its business as presently
conducted. The Company and each of its subsidiaries is qualified to do business
as a foreign corporation in each jurisdiction in which the ownership of its
property or the nature of its business requires such qualification, except where
failure to so qualify would not have a material adverse effect on the Company
and its subsidiaries taken as a whole.

            3.2  Capitalization. The authorized capital stock of the Company
consists of 20,000,000 shares of Common Stock, no par value, of which 11,536,075
shares were issued and outstanding on April 30, 1999, and 4,000,000 shares of
Preferred Stock, none of which are issued and outstanding as of the date hereof.
All issued and outstanding shares of Common Stock have been duly authorized and
validly issued and are fully paid and nonassessable.

            3.3  Authorization. The Company has all corporate right, power and
authority to enter into this Agreement and to consummate the transactions
contemplated hereby. All corporate action on the part of the Company, its
directors and shareholders necessary for the authorization, execution, delivery
and performance of this Agreement by the Company, the authorization, sale,
issuance and delivery of the Common Stock and the performance of the Company's
obligations hereunder has been taken. This Agreement has been duly executed and
delivered by the Company and constitutes a legal, valid and binding obligation
of the Company enforceable in accordance with its terms, subject to laws of
general application relating to bankruptcy, insolvency and the relief of debtors
and rules of law governing specific performance, injunctive relief or other
equitable remedies, and to limitations of public policy as they may apply to the
indemnification provisions set forth in Section 7.3 of this Agreement. Upon
issuance and delivery of the Share Certificates, the Shares will be validly
issued, fully paid and nonassessable and will be free of any liens or
encumbrances. The execution and delivery of this Agreement, and the issuance of
the Shares will not give rise to any preemptive right or right of first refusal
or right of participation on behalf of any person.

            3.4  No Conflict. The execution and delivery of this Agreement does
not, and the consummation of the transactions contemplated hereby will not,
conflict with, or result in any violation of or default (with or without notice
or lapse of time, or both), or give rise to a right of termination, cancellation
or acceleration of any obligation or to a loss of material benefit, under, any
provision of the Articles of Incorporation or Bylaws of the Company or any
material mortgage, indenture, lease or other material agreement or instrument,
permit, concession,

                                       2

franchise, license, judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to the Company and its subsidiaries or their properties or
assets.

as amended (the "Exchange Act"). All reports required to be filed by the Company
with the Securities and Exchange Commission ("SEC") during the period from March
31, 1998 to the date of this Agreement pursuant to Section 13(a) or 15(d) of the
Exchange Act, including the Company's Annual Report on Form 10-K for the fiscal
year ended March 31, 1998 (the "Form 10-K"), have been duly and timely filed,
were in compliance with the requirements of their respective forms, were
complete and correct in all material respects as of the dates at which the
information was furnished and as of their respective dates did not contain any
untrue statement of a material fact or omit to state a material fact necessary
to make the statements made therein, in the light of the circumstances under
which they were made, not misleading. Copies of the Form 10-K and the Form 10-Qs
required to be filed by the Company with the SEC during the period from March
31, 1998 to the date of this Agreement pursuant to Section 13(a) or 15(d) of the
Exchange Act (the "SEC Reports") have been furnished to the Purchasers. The
Company is an issuer eligible to use Form S-3 under the Securities Act of 1933

Shares (as that term is defined below in Section 7.1 (c)).

            3.6  Governmental Consent. No consent, approval or authorization of
or designation, declaration or filing with any governmental authority on the
part of the Company is required in connection with the valid execution and
delivery of the Agreement, or the consummation of any other transaction
contemplated hereby, except for any post-closing filings as may be required
under applicable federal or state securities laws, which will be timely filed
within the applicable periods therefor and except for the filing with the SEC of
a registration statement on Form S-3 for the purpose of registering the Common
Stock.

            3.7  Securities Act Exemption. Assuming and relying in part on the
truth and accuracy of Purchasers' representations and warranties in Section 4 of
this Agreement, the offer, sale and issuance of the Shares is exempt from
registration under the Securities Act and state securities laws.

     Section 4.  Representations, Warranties and Covenants of the Purchasers.
Each of the Purchasers represents and warrants to, and covenants with, the
Company that the following are and will be, true and correct as of the date
hereof and as of the Closing Date.

            4.1  Authority. Such Purchaser has full right, power, authority and
capacity to enter into this Agreement and to consummate the transactions
contemplated hereby. This Agreement has been duly executed and delivered by such
Purchaser and constitutes a legal, valid and binding obligation of such
Purchaser enforceable in accordance with its terms, subject to laws of general
application relating to bankruptcy, insolvency and the relief of debtors and
rules of law governing specific performance, injunctive relief or other
equitable remedies, and to limitations of public policy as they may apply to the
indemnification provisions set forth in Section 7.3 of this Agreement.

<PAGE>

            4.2  Investment Experience; Investment Intent, etc. (i) The
Purchaser, taking into account the personnel and resources it can practically
bring to bear on the purchase of the Shares contemplated hereby, is
knowledgeable, sophisticated and experienced in making, and is qualified to
make, decisions with respect to investments in shares presenting an investment
decision like that involved in the purchase of the Shares; (ii) the Purchaser is
acquiring the number of Shares to be purchased by it in the ordinary course of
its business and for its own account solely for investment and with no present
intention of distributing any of such Shares, and no arrangement or
understanding exists with any other person regarding the distribution of such
Shares; (iii) the Purchaser will not, directly or indirectly, offer, sell,
pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase
or otherwise acquire or take a pledge of) any of the Shares except in compliance
with the Securities Act, and the rules and regulations promulgated thereunder;
and (iv) the Purchaser is an "accredited investor" within the meaning of Rule
501 of Regulation D promulgated under the Securities Act.

            4.3  Purchaser Understanding and Agreements. The Purchaser
acknowledges and agrees that it will acquire the Shares being purchased by it in
transactions not involving a public offering and that such Shares are subject to
certain restrictions as to resale under the federal and state securities laws.
The Purchaser agrees and understands that until satisfaction of the conditions
set forth in Section 2(c), stop transfer instructions will be given to the
transfer agent for the Shares and each Share Certificate, and each certificate
delivered on transfer of or in substitution for any such certificate, shall bear
a legend in substantially the following form:

     The shares represented by this certificate are subject to restrictions
     imposed by the Securities Act of 1933, as amended, and applicable state
     securities law.  The shares may not be sold or transferred in the absence
     of registration or an exemption therefrom under the Securities Act of 1933
     and any applicable state securities laws.

     The Purchaser agrees that it will not sell, pledge, assign, transfer or
otherwise dispose (collectively, "Transfer") of any of the Shares unless the
Transfer will be made pursuant to an exemption from the registration
requirements of the Securities Act or pursuant to an effective registration
statement under the Securities Act and pursuant to an exemption from any
applicable state securities laws or an effective registration or other
qualification under any applicable state securities laws.  The Purchaser
understands that exemptions from such registration requirements are limited.
The Company is under no obligation to register the Shares except as provided in
Section 7.

            4.4  Transfer of Shares after Registration. The Purchaser hereby
covenants with the Company not to make any sale of the Shares after registration
without effectively causing the prospectus delivery requirement under the
Securities Act to be satisfied. The Purchaser acknowledges that there may be
times when the Company must suspend the use of the prospectus forming a part of
the Registration Statement (as defined below) until such time as an amendment to
the Registration Statement has been filed by the Company and declared effective
by the SEC, or until such time as the Company has filed an appropriate report
with the SEC pursuant to the Exchange Act. The Purchaser hereby covenants that
it will not sell any Shares pursuant to said prospectus during the period
commencing at the time at which the Company

                                       4
<PAGE>

gives the Purchaser notice of the suspension of the use of said prospectus and
ending at the time the Company gives the Purchaser notice that the Purchaser may
thereafter effect sales pursuant to said prospectus. Such period shall in no
event exceed 30 business days in any 12 month period.

            4.5  No Legal, Tax or Investment Advice. The Purchaser understands
that nothing in this Agreement or any other materials presented to the Purchaser
in connection with the purchase of the Common Stock constitutes legal, tax or
investment advice. The Purchaser has consulted such legal, tax and investment
advisors as it, in its sole discretion, has deemed necessary or appropriate in
connection with its purchase of the Common Stock.

     Section 5.  Conditions to Obligations of Purchaser at Closing Date.  The
obligation of each Purchaser to purchase the Common Stock is subject to the
fulfillment on or prior to the Closing Date of the following conditions, any or
all of which may be waived in writing at the option of all Purchasers:

            5.1  Representations and Warranties Correct. The representations and
warranties made by the Company in Section 3 shall be true and correct when made
and shall be true and correct in all material respects on the Closing Date with
the same force and effect as if they had been made on and as of said date.

            5.2  Covenants. All covenants, agreements and conditions contained
in this Agreement to be performed by the Company on or prior to such Closing
Date, shall have been performed or complied with in all material respects.

            5.3  No Order Pending. There shall not then be in effect any order
enjoining or restraining the transactions contemplated by this Agreement.

            5.4  No Law Prohibiting or Restricting Such Sale of Shares. There
shall not be in effect any law, rule or regulation prohibiting or restricting
sale of the Shares, or requiring any consent or approval of any person which
shall not have been obtained to issue the Shares.

            5.5  Legal Opinion. Each Purchaser shall have received a legal
opinion of Cooley Godward LLP, dated the Closing Date, to the effects set forth
in Exhibit A.

     Section 6.  Conditions to Obligations of Company at the Closing Date.  The
Company's obligation to execute and deliver the Share Certificates at the
Closing is subject to the fulfillment on or prior to the Closing Date of the
following conditions, any or all of which may be waived in writing at the option
of the Company:

            6.1  Representations and Warranties Correct. The representations and
warranties made by the Purchasers in Section 4 hereof shall be true and correct
when made, and shall be true and correct in all material respects on the Closing
Date with the same force and effect as if they had been made on and as of said
date.

     Section 7.  Registration of the Shares; Compliance with the Securities Act.

            7.1  Definitions. For the purpose of this Section 7 the following
terms shall have the following respective meanings:

                 (a)  the term "Registrable Shares" shall mean the shares of
Common Stock issued pursuant to this Agreement;

                 (b)  the term "Registration Statement" shall mean any
registration statement required to be filed by Section 7.2 below, and shall
include any preliminary prospectus, final prospectus, exhibit or amendment
included in or relating to such Registration Statement; and

                 (c)  the term "Untrue Statement" shall include any untrue
statement or alleged untrue statement, or any omission or alleged omission to
state in the Registration Statement a material fact required to be stated
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

            7.2  Registration Procedures and Expenses. The Company shall within
90 days following the Closing Date:

                 (a)  prepare and file with the SEC an S-3 registration
statement under the Securities Act (providing for shelf registration of the
Common Stock under SEC Rule 415) on a form which is appropriate to register all
of the Registrable Shares;

                 (b)  use its best efforts, subject to receipt of necessary
information from the Purchasers, to cause such Registration Statement to become
effective as promptly after filing as practicable and thereafter to use its best
efforts to keep such Registration Statement continuously effective for the
resale of the Registrable Shares until all such Registrable Shares are sold;

                 (c)  prepare and file with the SEC such amendments and
supplements to such Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective
until termination of such obligation as provided in Section 7.6 below;

                 (d)  furnish to each Purchaser (and to each underwriter, if
any, of such Common Stock) such number of copies of prospectuses in conformity
with the requirements of the Securities Act and such other documents as the
Purchasers may reasonably request, in order to facilitate the public sale or
other disposition of all or any of the Registrable Shares by the Purchasers;

                 (e)  prepare and file such documents as may be required of the
Company for normal securities law clearance for the resale of the Registrable
Shares in which states of the United States as may be reasonably requested by
each Purchaser provided, however, that the Company shall not be required in
connection with this paragraph (e) to qualify as a foreign corporation or
execute a general consent to service of process in any jurisdiction;

                                       6
<PAGE>

                 (f)  advise each Purchaser promptly:

                      (i)   of any request by the SEC for amendments to the
Registration Statement or amendments to the prospectus or for additional
information relating thereto:

                      (ii)  of the issuance by the SEC of any stop order
suspending the effectiveness of the Registration Statement under the Securities
Act or of the suspension by any state securities commission of the qualification
of the Registrable Shares for offering or sale in any jurisdiction, or the
initiation of any proceeding for any of the preceding purposes; and

                      (iii) of the existence of any fact and the happening of
any event that makes any statement of a material fact made in the Registration
Statement, the prospectus, and amendment or supplement thereto, or any document
incorporated by reference therein untrue, or that requires the making of any
additions to or changes in the Registration Statement or the prospectus in order
to make the statements therein not misleading;

                 (g) upon the occurrence of any event described in Section
7.2(f)(ii) above, use its commercially reasonable efforts to obtain the
withdrawal of any order suspending the effectiveness of any such Registration
Statement or the lifting of such suspension;

                 (h) use its best efforts to cause all Registrable Shares to be
listed on each securities exchange or automated interdealer quotation system, if
any, on which equity securities by the Company are then listed or quoted;

                 (i) bear all expenses in connection with the procedures in
paragraphs (a) through (g) of this Section 7.2 and the registration of the
Registrable Shares on such Registration Statement and the satisfaction of the
blue sky laws of such states, other than any (i) fees and expenses, if any, of
counsel or other advisors to the Purchasers and (ii) expenses relating to the
sale of the Registrable Shares by the Purchasers, including broker's commission,
discounts or fees and transfer taxes; and

                 (j) on or before the effective date of such Registration
Statement provide the transfer agent of the Company with printed share
certificates for the Registrable Shares.

       7.3  Indemnification.

                 (a) The Company agrees to indemnify and hold harmless each
Purchaser (and each of its officers, directors, partners or persons, if any, who
controls such Purchaser within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act) from and against any losses, claims, damages
or liabilities to which such Purchaser (and each of officers, directors,
partners or persons, if any, who controls such purchaser within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) may become
subject (under the Securities Act or otherwise) insofar as such losses, claims,
damages or liabilities (or actions or proceedings in respect thereof) arise out
of, or are based upon, any Untrue Statement on the effective date thereof, or
arise out of any failure by the Company to fulfill any undertaking included in
the Registration Statement, and the Company will, as

                                       7
<PAGE>

incurred, reimburse such Purchaser (and each of its officers, directors,
panniers or persons, if any, who controls such Purchaser within the meaning of
Section 5 of the Securities Act) for any legal or other expenses reasonably
incurred in investigating, defending or preparing to defend any such action,
proceeding or claim; provided, however, that the Company shall not be liable in
any such case to the extent that such loss, claim, damage or liability arises
out of, or is based upon, an Untrue Statement made in such Registration
Statement in reliance upon and in conformity with written information furnished
to the Company by or on behalf of such Purchaser specifically for use in the
Registration Statement.

            (b)  Each Purchaser, severally and not jointly, agrees to indemnify
and hold harmless the Company (and each person, if any, who controls the Company
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act, each officer of the Company who signs the Registration Statement
and each director of the Company), from and against any losses, claims, damages
or liabilities to which the Company (or any such officer, director or
controlling person) may become subject (under the Securities Act or otherwise),
insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon, any Untrue
Statement with respect to such Purchaser on the effective date thereof, if, and
to the extent, such Untrue Statement was made in reliance upon and in conformity
with written information furnished by or on behalf of such Purchaser
specifically for use in the Registration Statement, and such Purchaser will, as
incurred, reimburse the Company (and each of its officers, directors or
controlling persons) for any legal or other expenses reasonably incurred in
investigating, defending or preparing to defend any such action, proceeding or
claim; provided that in no event shall any indemnity by a Purchaser under this
Section 7.3 exceed the net proceeds received by such Purchaser from the sale of
the Registrable Shares by such Registration Statement.

            (c)  Promptly after receipt by any indemnified person of a notice of
a claim or the beginning of any action in respect of which indemnity is to be
sought against an indemnifying person pursuant to this Section 7.3, such
indemnified person shall notify the indemnifying person in writing of such claim
or of the commencement of such action, and, subject to the provisions
hereinafter stated, in case any such action shall be brought against an
indemnified person and such indemnifying person shall have been notified
thereof, such indemnifying person shall be entitled to participate therein, and,
to the extent that it shall wish, to assume the defense thereof, with counsel
reasonably satisfactory to such indemnified person. After notice from the
indemnifying person to such indemnified person of its election to assume the
defense thereof, such indemnifying person shall not be liable to such
indemnified person for any legal expenses subsequently incurred by such
indemnified person in connection with the defense thereof; provided, however,
that if there exists or shall exist a conflict of interest that would make it
inappropriate in the reasonable judgment of the indemnified person for the same
counsel to represent both the indemnified person and such indemnifying person or
any affiliate or associate thereof, the indemnified person shall be entitled to
retain its own counsel at the expense of such indemnifying person; provided,
however, that no indemnifying person shall be responsible for the fees and
expenses of more than one separate counsel for all indemnified parties.

            (d) If after proper notice of a claim or the commencement of any
action against the indemnified party, the indemnifying party does not choose to
participate, then

                                       8
<PAGE>

the indemnified party shall defend itself at its own cost and expense until
there is an adjudication at which point the indemnifying party shall then
reimburse the indemnified party for its costs and expenses.

            (e)  If the indemnification provided for in this Section 7.3 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged Untrue Statement of material fact or the omission
to state a material fact relates to information supplied by the indemnifying
party or by the indemnified party and the parties' relative intent, knowledge,
access to information, and opportunity to correct or prevent such statement or
omission; provided, that in no event shall any contribution by a Purchaser
hereunder exceed the net proceeds received by such Purchaser from the sale of
the Registrable Shares covered by the Registration Statement. No person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

     7.4  Prospectus Delivery. Each Purchaser hereby covenants with the Company
to comply with the prospectus delivery requirements in connection with the
resale of the Registrable Shares.

     7.5  Assignability of Registration Rights. The registration rights set
forth in this Section 7 are not assignable other than to an affiliate of a
Purchaser.

     7.6  Termination of Obligations. The obligations of the Company pursuant to
Sections 7.2 hereof shall cease and terminate upon the earlier to occur of (i)
such time as all of the Registrable Shares have been re-sold, or (ii) such time
as all of the Registrable Shares may be re-sold pursuant to Rule 144(k) of the
Securities Act.

     7.7  Reporting Requirements.

          (a)  With a view to making available the benefits of certain rules and
regulations of the SEC that may at any time permit the sale of the Shares to the
public without registration or a registration on SEC Form S-3, the Company
agrees to:

               (i)  make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act;

               (ii) file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

Securities, to furnish to the Purchasers forthwith upon request (1) a written
statement by the Company as to whether it complies with the reporting
requirements of said Rule 144, the Securities Act and Exchange Act, or whether
it qualifies as a registrant whose securities may be resold pursuant to SEC Form
S-3, (2) a copy of the most recent annual or quarterly report of the Company and
such other reports and documents so filed by the Company, and (3) such other
information as may be reasonably requested in availing the Selling Shareholders
of any rule or regulation of the SEC that would permit the selling of the
Registrable Shares without registration.

     Section 8.  Legal Fees and Expenses. Each of the parties shall pay its own
fees and expenses in connection with this Agreement and the transactions
contemplated hereby, except as provided in Section 7 with respect to the
Registrable Shares.

     Section 9.  Notices. All notices, requests, consents and other
communications hereunder shall be in writing, shall be telecopied or mailed by
first class registered or certified airmail (return receipt requested), postage
prepaid, and shall be deemed given when so telecopied or, if mailed, when

have been furnished by such transferee or transferees to the Company in writing.

(BW) (CA-ASYST-TECHNOLOGIES) (ASYT) Asyst Technologies to Acquire Progressive
System Technologies, Inc.

     Business Editors/High-Tech Writers

     FREMONT, Calif.--(BUSINESS WIRE)--April 19, 1999--

        Enhances Marketshare Leadership for Automated Wafer Management
             Systems and Strengthens Position in Emerging Reticle
                         Automation Management Market

     Asyst Technologies, Inc. (Nasdaq:ASYT), the leading supplier of Standard
Mechanical InterFace (SMIF) isolation and manufacturing automation solutions to
the semiconductor industry, announced today that it has signed a letter of
intent to acquire Progressive System Technologies, Inc. (PST) (Austin, Texas), a
supplier of substrate management systems for open-cassette, SMIF-integrated
wafer logistics and reticle automation.  With the acquisition, Asyst enhances
its position as a leading global supplier of automated wafer management
solutions and strengthens its position in the emerging reticle automation
management market.
     The anticipated transaction is to be accounted for as a pooling of
interests and, based on Asyst's current share price, the transaction would have
a value of approximately $10 million.
     According to industry analyst firm VLSI Research Inc. (San Jose, Calif.),
the automated wafer management systems market, which includes wafer/reticle
transfer systems and stockers, is projected to exceed $280 million in the year
2001.  This market is being driven by the need for increased levels of wafer
automation, SMIF and non-SMIF facility upgrades, and increased automation
requirements for 300 mm processing.  Increasing circuit complexity is driving
the need for reticle manufacturers to attain the same automation and
contamination control benefits SMIF now provides the semiconductor industry.
Reticles, which are quartz substrates with patterns used in conjunction with
wafer steppers to print sub-micron images on wafers, are sensitive to particle
contamination and subject to misprocessing -- just as are semiconductor wafers.
     Commenting on the acquisition, Asyst's President and Chief Operating
Officer Terry Moshier noted that PST's offerings are very synergistic with
Asyst's.  "Asyst's core competencies lie in automation and SMIF isolation
solutions for wafer processing, while PST's expertise lies in automated reticle
and wafer management -- particularly for open cassette applications.  Moshier
added, "This strategic step positions Asyst to offer a broader range of advanced
automation capabilities to both SMIF and open-cassette fab environments.  Asyst
will leverage its current global sales and service infrastructure to provide our
customers with solutions that enhance productivity and reduce cost of ownership.
The PST acquisition augments Asyst's strategic thrust to offer substrate
handling
<PAGE>

automation solutions to our customers, who include both OEM equipment suppliers
and IC manufacturers."
     Asyst, with PST, is uniquely positioned to offer the industry advanced
reticle management solutions.  Asyst will build upon its expertise in tool
front-end integration for wafer processing and integrate its current reticle
handling products, which include single and multiple reticle pods and loadport
transfer for reticles, with PST's reticle storage and handling systems.
According to Asyst, orders are pending for PST's substrate management systems
to customers located in North America, Asia and Europe.
     Tony DiNapoli, PST's founder, will assume the role of vice president,
reporting directly to Moshier.  DiNapoli will be chartered with managing the
Austin-based products group for Asyst.  The transaction is expected to be
finalized in the next few months.  Upon closing, Asyst and PST will rapidly
integrate sales, service and marketing efforts, as well as their respective
product offerings.
     Separately, Asyst announced that in connection with the merger with PST,
the Board of Directors of Asyst has rescinded the Company's stock repurchase
program.  As of March 31, 1999, the Company has repurchased 865,800 shares of
common stock at an aggregate cost of approximately $11.5 million, pursuant to
the repurchase program originally instituted in June 1998.
